And further north, Chencang Ancient Road was about to rush into Shangguan City of Dasanling, there was also a scene of soldiers and horses running around in chaos. Balls of arrows, wood and stones were transported to the top of the city, and many blood-stained wounded and corpses were transported down.

Looking down from the broken braces on both sides of the city, as most of the rebels who came from outside the pass, pressing large platoons in groups, and under the attack of the car crash and long ladders, it became increasingly precarious.

Although outside the gate tower of Guancheng, there were already piles of broken equipment and blood flowing into corpses, the people from the camp below still rushed up with endless impacts.

Again, among the deaths and injuries caused by arrows and stones like rain, rolling wood and dust bottles, the struggle to climb onto the city wall became increasingly sparse and became increasingly weak.

Every time they climbed to the top of the city, it means that the official army suffered another tragic casualties in the melee, as well as more destroyed and destroyed city defense facilities. As the guard general who insisted on being on the top of the city, Lu Hongyan has become a bloodless person.

There was even an arrow that he couldn't pull out, which was the price he cut down a thief who raised the flag first and broke the flag and threw it out.

The personal soldiers gathered around him also became sparse, and everyone was injured and could not hide their fatigue and depressed colors; the look of looking at him was still firm and trustworthy.

However, Lu Hongyan forced himself to face their eyes; because he promised and promised again and again that their reinforcements would definitely arrive. But in fact, he didn't know where the so-called reinforcements were.

As the last stronghold for the official army to guard the pass, at its peak, there were 67,000 soldiers including the Right Shence Army, Zhongwu Badu, Xichuan Huangtou and Shenji Army, Tu Zhengying, Shanxi Shenjian Army and Zitong Army.

However, Xinshijiu went on a sudden turn. First, he left Wudu with the mutiny of Zhongwu and only recovered Han Jian's troops; then, the Shanxi Jiedushi Niu Xu was expelled by Song Hao, and Shanxi Shenjian Army left on his own worried about his family.

Then, Yang Shili, the governor of Dongchuan, refused to become a minister. As a result, all the Zitong soldiers in the pass were disarmed and the establishment was disbanded and the other troops were added to the other troops. As a result, many of them ran away overnight.

Then came the news that Chen Jingxuan, the governor of Xichuan, robbed the emperor of rebellion. The Huangtou Army immediately collapsed in civil strife. The remaining Shenji Army suddenly controlled the situation under the purging of Er Yang.

Then, under the leadership of Yang Shumi, most of the troops were divided into two groups and headed south to serve the king; so now there are only three Zhongwu, some Huangtou Army, as well as the gang trainers who were transferred from Fengzhou to make up the numbers.

But at least it was the beginning of spring all winter, and the thieves in the pass suffered heavy losses and were powerless. Therefore, they had a rare time to recuperate and recuperate, and even built the city walls and guardrails near Chencang (now Baoji City).

As a result, just as the summer approached, suddenly a vast army of thieves attacked, and Fengxiang Town, which was supposed to serve as a support and arriving at the corner, did not even issue any warnings or signs.

Moreover, these thieves were generally highly morale and well-equipped than those of the official army; not to mention that they were mixed with Fengxiang, Yanning and Weibei Army, and the military camps they first came into contact with were easily deceived and captured.

As a result, the official army, which originally had nearly 15,000 members, was caught off guard and lost a small part of the defeats along the way. By the time the bandit army reached the foot of Dasanling, there were less than ten thousand defenders in the city.

As the strongest generals of the Huangtou Army, the two generals of the official army, fled to death and then elected him, the number one general of Zhongwu, to the sickbed of Xiao Yang's governor, and became the leader now.

However, now his various means have been exhausted; including asking people to organize civilians from Liangquan County to waving flags in the rear, and making a large number of military and Malay aid strategies, which were easily seen through by the thief army back then.

So he didn't know how long he could last, whether he would die in the next round or in the next few rounds of the thief attack. Thinking of this, he couldn't help but call his own soldiers and asked:

"Have Xiao Yang's carriage and horse set off?"

"I returned to the capital, and the capital magistrate vowed to live with Guancheng, and they scolded us..."

However, this personal soldier showed a kind of sad expression:

"Then you just think of some ways, even if you send the person to the state city first just in case..."

Lu Hongyan didn't have any energy to do it:

At this time, the military in charge of looking out on the city suddenly shouted loudly while beating the gong:

"Be careful... cannon stone..."

However, before he finished speaking, he heard the whistling sound in the air coming immediately; but as he carried a large row of black and covered the thieves, many stones of different sizes smashed on the walls and the ground, splashing a lot of dust.

Although only a few of them hit Guancheng, the land collapsed and the walls were cracked, and they peeled off one after another, bursting out a large piece of rammed earth.

There was also a wooden arrow tower with a straight wooden look at the building. Several archers were covered in blood in the debris and ruins before they could even scream and scream.

Seeing this scene, Lu Hongyan couldn't help but be stunned. Obviously, under the cost of transporting and transporting the thief army, they actually recovered the ruggedness of the narrow and long valley roads, and transported all the stone cannons and other equipment to Guancheng.

This was undoubtedly a heavy blow to the morale and fighting spirit that the official army could only maintain; with the second round of bombardment that followed, it fell into the crowd of wives gathered in the city, and suddenly ran away in scattered like a blast.

At first there were soldiers in charge of guarding, who were yelling and beating and trying to drive them back again; but as several civilians knocked down, the officers and soldiers intercepted on the fence behind the back fence flew into the field, and things suddenly became out of control.

"Shoot the arrow quickly..."

Lu Hongyan, who had just turned around, shouted loudly when he knew something was wrong, but it was too late.

Before the archers who turned around and opened their bowstrings, the officers and soldiers in charge of guarding the city also turned around and pushed them down when they saw that the situation was not good, chopped open the fence, and entered the footsteps of the fleeing civilians.

At this time, the thieves who had cleared the passage in front of the door also began to make violent sounds of hitting the door.

——I am the dividing line—

Outside Jiangning City, boats gathered again and showed a trend of returning home with a full load. Zhou Huaian, standing on the deck of the ship, looked at the scenery of Jiangbei vaguely among the fireworks on the other side, and sighed with regret.

Well, this time I took advantage of the opportunity to make "The Seven-character Scripture: Taiping Army Occupies Liuhe", and I will miss it like this. At least in the short term, the Taiping Army is no longer suitable to attack Huainan on a large scale.

He originally planned to take the women who were new to visit the scenery and historical sites in Jiangnan that were still a long history even in this era. As a result, after the incident of Xiajiang, he had to come and go back home in a hurry.

On the one hand, this is because of the cycles needed to digest and consolidate the basic Jiangdong market. On the other hand, it is because I cannot leave the Grand Commander Center in Jiangling for too long, resulting in a deviation in the economic and military center of gravity.

Because over time, some problems that have been concealed by a series of achievements after the victory are gradually emerging; such as delays in execution and response mechanisms, and the imbalance trend of power structure and economic circulation.

This time, Yuzhou is in a hurry, which is the best example. If these accumulated factors continue to break out, it will not be so easy to clean up and rectify. Therefore, no matter how good the wind and things in Jiangdong are, we can only ask for it for the time being.

After all, the current political core and economic system of the Taiping Army General Office are still based on the transportation capacity and transportation convenience provided by the Jianghan-middle and lower reaches of the Yangtze River-Xiangshui-Zhujiang River and other water systems to operate and regulate.

Therefore, the location of Jiangling, Jingzhou, which is a central hub, is still irreplaceable. However, in Jiangdong, unless the laying of wall signal tower outlets and the transformation of local social structure and economic foundations is completed, the economic center cannot be shifted no matter how you say it is.

Thinking of this, Zhou Huaian is increasingly looking forward to the small-scale experiment and trial cable telegraph network in the Pearl River Basin in Lingnan. In a sense, the threshold for this primitive electrical signal propagation method is not high, but there are many problems in the details of the trial.

For example, wiring and poles on the flat ground are relatively simple. These new lines can be arranged side by side with the original station and signal tower system and managed and operated with ready-made manpower, or this can obtain some subsidy projects on the spot.

The copper, zinc, metal, and catalysts such as green alum/sulfuric acid required for water tank reaction batteries have ready-made industrial output; not to mention the wire and glue that are wires, they also have ready-made batch products.

However, when encountering the paving of cross-river and cross-river routes, as well as subsequent patrol and maintenance methods, it is a time-consuming and laborious thing that requires continuous debugging and exploration; it can be said that the relatively complex terrain and trends south of the Five Ridges, as well as seasonal mountain torrents and wind disasters, are all potential threats and challenges.

However, once the first long-distance network cable is completed, the various problems and potential development bottlenecks encountered by the Grand Governor's Office after the great expansion of its rule can be solved at once.

Needless to say, the coastal areas along the Yangtze River from Yuzhou to Runzhou can achieve an efficiency that can be heard in a flash and can be seen day and night. The bonus of dominance and execution efficiency and countermeasure responses has not only increased a few times.

Unfortunately, things like the science and technology tree can certainly take shortcuts through predicted factors; but if you want to transform from handmade products in the laboratory into industrial products that are sufficient for mass production, you need to constantly accumulate enough experience in trial and error of various solutions to achieve natural qualitative changes.

On the other hand, the problems encountered in the implementation of further firearming in the eleven regular military orders were encountered; the main reason was that the relatively standardized gun cannon production technology and equipment plan, and the source of raw materials in gunpowder production gradually approached a basic upper limit;

At least before opening up more sources of sulfur and saltpeter (such as Japan), it is impossible to make a breakthrough. After all, there are not many minerals such as saltpeter sulfur in the south, and the mining efficiency is not high (salt ore with biological organisms).

Therefore, as a further upgrade product, the production of various nitrates has not been satisfactory; at present, we can only prioritize the production of explosive raw materials for engineering blasting and military attacks; as a remote projection launcher, it still relies on the refined and purified granulated black gunpowder pack to continue carrying the beam.

On the other hand, after obtaining the land and population in such a large area of ​​Jiangdong, it is also a huge burden and source of negative growth in a short period of time. Especially when the Taiping Army Governor's Office does not intend to let them die on their own, but rather organizes them to resume production as much as possible.

In addition to the expenses required to maintain local military presence and public security elimination, there are also a large number of good varieties, livestock and agricultural tools allocated and invested, as well as the planning and implementation of specific production division of labor and organization.

Fortunately, the demand for other aspects is good, and there are ready-made materials and objects to be adjusted; but the most important thing is that the production quota of agricultural fertilizers in Xintunzhuang is inevitable.

As a basic element mainly based on nitrogen, phosphorus and potassium, traditional nitrogen fertilizer can be made by collecting aquatic plants, silt and crop rhizomes and leaves on site, and fermenting green manure; phosphorus fertilizer can be supplemented by searching for years of struvite from coastal islands.

But there is really no way to potassium fertilizers. They can only be prepared from raw materials such as natural minerals and hard salt ores through industrialization and means; such as potassium sulfate in salt lake crystals and potassium chloride extracted from bitter brine in salt wells.

This requires collecting from the Xiajiang Road in the upper reaches of the Yangtze River, then releasing it down the Jiangdong Road, and further processing is carried out by local hydraulic workshops and workshops to gradually meet the basic needs of various places for field and villages.

Therefore, the same is true for pesticides that can effectively kill pests and diseases, such as realgar water, Bordeaux liquid, lime sulfur mixture, and even organic ingredients tobacco (grass) tar, pine resin, pyrethrum, vines, etc.

After all, in this era where there are no chemical fertilizers and pesticides, and can only rely on precise cultivation to maximize the output, once these auxiliary means are invested in the gain effect in agricultural production, it is almost an explosive result of increased yields.

In a sense, this is also part of the "destiny of heaven" that the Taiping Army has declared and firmly believed in; because as long as it is the Tunzhuang established by the Taiping Army, whether it is land production or production efficiency, it will have a lot of benefits in the surrounding areas.

On the one hand, this greatly enhanced the attractiveness of attracting and reclaiming the corresponding cultivation; on the other hand, it also cracked down on and weakened the remnants of the traditional powerful and landlords, and the power and influence of the villages that had once controlled.

After all, ordinary poor people may not be able to read and cannot understand any principles or opinions; but they can truly feel the benefits of land production increase; this is much more effective than just empty talk and white teeth advocating and promoting it ten thousand times.

Then, people will naturally take the initiative to contact and try to communicate with them in order to find or explore the secret of corresponding abundant yields. In this way, the influence spreading with each village as the center will easily become a strong support point for stabilizing the local situation.

What's even better is that these key lifelines and materials for increasing production and harvest are all controlled by the Taiping Army's production system; even if others want to secretly imitate and imitate, they cannot learn it at all.

In this way, if local people who come from local backgrounds want to obtain these gains and benefits, they can only actively seek opportunities for cooperation and learning from the Taiping Army's settlement system; even in the form of enlistment and acceptance of corvee, they gradually became part of the Taiping Army's ruling system and order.

Although there are many complicated things and projects, although there are generally mature systems to operate, Zhou Huaian still needs to provide guidance and judgments in the corresponding general direction at many key nodes; in order to avoid development incorrectly or going back to the right direction.

Therefore, although later generations have complained about the person who likes to point fingers at the frontline and slightly interfere with the grassroots troops, Zhou Huaian is eager to be unable to split up his body to solve and guide these endless problems one by one.

Then, a soft body was pressed from Zhou Huaian's back and said:
Chapter completed!
