To the east of Mangshan Mountain, on the surface of the Yellow River, a bridge flows north and south, and the natural barrier becomes a thoroughfare. This is an unprecedented Yellow River bridge with a total length of nearly six miles. It is a truss structure and a reinforced concrete bridge deck.

The Yellow River Bridge, which was completed in five years, has 107 bridge holes and 108 bridge piers. The piers penetrate the silt of the riverbed and reach the mud-bottom rock layer. The underground length is more than ten feet, which is extremely firm.

Whether during the flood season or the ice season, the piers of the Yellow River Bridge have withstood the tests. The railway tracks laid on the bridge deck have vehicles traveling between the north and the south every day.

What kind of car is it? Steam train.

The steam train departing from Xiakou, pulling a long carriage full of cargo and passengers, arrives on the north bank of the Yangtze River through the Yangtze River Bridge, and then crosses Tongbai Mountain along the railway, enters the boundary of Henan, and heads north.

Enter the boundary of Hebei through the Yellow River Bridge.

The locomotive roared, constantly spraying thick smoke, pulled the long carriage through the Yanzhao land, crossed the Yanshan Mountains, entered the western boundary of Liaoning along the Lulong Railway, and then turned to Liaodong.

In the special waiting carriage, he was eating hot pot and drinking wine, looking at the black soil in the northeast outside the window, and humming happily: "Our no-ga is all Northeast silver..."

"Dang, dang, dang..."

As Huang Zhong said, the scene in front of him changed and became distorted. Yu Wen Wen opened his eyes and found that he was indeed dreaming.

In his dream, he built a "Beijing-Han Railway" with picy acid explosives, which was connected to the railway "outside the pass", from then on, and could not be separated.

The dream is fake, the bell sounds are real, and it is the time to be reported on the bell tower on campus, urging students to get up.

Although the distance was a little farther, you could still hear the bells in the palace. Yu Wenwen turned his head and looked at the bell and found that it was exactly six o'clock.

At about six o'clock, it is time for the students to get up. After washing, they packed up their textbooks and homework books, carried their schoolbags to the canteen for breakfast, and then went to the classroom to take morning reading classes.

Yuwen Wen sat up and saw Zhang Lihua who was still sleeping beside him, gently put on her clothes and slowly got off the bed.

He opened the window and sat by the window, breathing the fresh air, feeling the birds singing and flowers outside the window, and felt the feeling of relaxation and happiness.

Autumn begins in the blink of an eye. Yuwen Wen has been in a good mood for a while. He has been in Yecheng for more than two months and has done a lot of things. He has met with talented people from all over Hebei, recruited talents, inspected the construction site of Yongji Canal, and visited the surrounding people's conditions.

He fulfilled the obligations that an emperor deserved very well.

What made him happiest was that he received the good news yesterday - picy and sour, which was "copied".

Pyric acid is explosives, which was accidentally made out by the dyeing workshop technician. Yuwen Wen obtained the experimental records of these "pioneers" and then asked the chemical workshop in Xiyang, Huangzhou to "take medicine according to the prescription".

The technicians took a month to successfully "copy" the picric acid. After experiments, it was confirmed that this thing is amazingly powerful.

It's really expensive.

The same weight of picric acid is more expensive than silver.

Due to the quality and yield of nitric acid, sulfuric acid, the yield of picric acid will not be large in the near future.

But for Yuwen Wen, the problem that can be solved with money is not a problem. You can still make money after spending money. Explosive, something that transcends the times, is a priceless treasure and is worth investing a lot of money to produce.

Yu Wen Wen was very happy to receive the good news. In addition to being extremely excited last night, he had a "very yellow and violent" game with Zhang Lihua who was "rotten".

After a night of hard work, Zhang Lihua was exhausted, but Yuwen Wen was energetic because his excitement had not passed.

With explosives, some major projects that you never dared to think of before can be carried out. Of course, this requires a large-scale construction to be carried out while sympathizing with the people's strength, but the bright prospects still make Yuwen Wen very excited.

Even if you are excited, you have to walk step by step and eat food one by one.

What ambition is to make sure that the process of making picric acid can be practical.

Then he has to reduce the production cost, otherwise he will not be able to afford it at all.

Even though there is still a long way to go to practicalize picric acid, Yuwen Wen is still full of confidence. He wants to make this era different, so he will never shrink from some difficulties.

After putting away the notes, Yuwen Wen asked the palace maid to prepare breakfast. He sat alone in front of the desk, looked at the official documents, and began to think about the current situation.

The Liaodong strategy is proceeding in an orderly manner. The Goguryeo Army's counterattack on the Liaodong Peninsula was repelled by the armed forces of the Beiyang Trading Company, and the official army has officially stationed several cities to strengthen its defensive forces.

The construction of Lushun Port is very smooth. Now it is just about autumn. Some of the grain harvested in Henan will be loaded into the sea through the Yellow River and transported to Lushun for stockpiling.

The pre-war preparations for Gao Gouli were in an orderly manner, but "the tree wants to be quiet but the wind does not stop", the northwest, which had been calm for several years, began to become restless.

Not long ago, two groups of envoys came to Yecheng one after another and brought the same request, that is, marriage.

The first group of envoys came from Tuyuhun. For the Khan Murong Fuyun of Tuyuhun, he proposed to the Emperor of Great Zhou, hoping to marry the princess of Zhou and make in-laws between the two countries.

The second group of envoys, from the Turks, came from the Turks, who proposed to the Emperor of Great Zhou for marriage, hoping to marry the princess of Zhou and continue the "traditional friendship" between the two countries.

A cheap son-in-law came to propose marriage. Yuwen Wen's reaction was the same as that of fathers from ancient times to the present and in China and abroad: Want to kidnap my daughter? Who are you?

Apart from this emotion, Yu Wen Wen actually had a conflict with the marriage. Of course, he did not have any opinions about the man who was trapped in the horse. He also knew that marriage was actually normal these days. In general, it was not a loss of power and humiliation of the country, but he just was not happy.

Because just relying on marriage, friendly relations between the two countries cannot be maintained at all.

This is true for the country and among the families. At that time, there were so many princes in the Yuwen family. As a result, in the second year of the elephant, how many people stood up?

Should I fight or fight, should I grab or grab, should I turn against you, and should I turn against you.

Since this is the case, he sent his daughter to marry him, but in fact there was no practical significance and could not play much role. The northwest border was still in peace.

Not to mention that although Yuwen Wen has many daughters, he now has no daughter who is suitable for marriage.

In addition to stepdaughter Yuwen Eying, among Yuwen Wen's biological daughters, the eldest daughter Yuwen Yueying (born by Xiao Jiuniang) reached the age of marriage last year, so she got married, and the second daughter Yuwen Huaying (born by Yang Lihua) also reached the age of marriage this year and is also married.

The "third brother" Yuwen Yuying was born by Yuchi Chifan. She is only seven years old now, so of course it is impossible to get married.

The princess is not suitable, and the royal family is also not suitable. The younger generation of royal family girls are Yuwen Wen's niece and the sister of Qi Wang Yuwen Li, who are already married.

Zhou State has informed the Turks that Tuyuhun was coming to this situation, but the other party still hopes to get married. The intention is actually very clear: for the sake of diplomatic relations between the two countries, whether it is true or false, let’s have a princess of Zhou!

The two countries' unanimous requests illustrate one problem, that is, their monarch urgently needs to marry Zhou State to gain political benefits, and they should be trying to use Zhou State as a tiger skin to scare the powerful and powerful in the country.

In other words, this is a face-saving project. It doesn’t matter whether the princess is really, as long as the person involved doesn’t say it out loud.

So Yuwen Wen can appreciate his face, learn from Wang Zhaojun's story, and make the two relatives princesses, and marry Turks and Tuyuhun respectively. Everyone is happy, and at least make the border stable for a few years.

Based on reality, this is the correct choice, and the officials of the Zhengshitang have no objection to this.

But Yuwen Wen just wasn't happy.

If Zhou State is at a time of internal and external troubles, it is understandable to make concessions. The problem is that Zhou State has unified the Central Plains and has recovered after several years of cultivation and rest.

Of course, Yuwen Wen hopes that the border will be peaceful and is sincerely willing to establish good relations with the Turks and Tuyuhun so that he can live a peaceful life for the people in the country, so that he can prepare for war.

Peace is very important, but it is too cowardly to sacrifice women to exchange for peace in the frontier years.

Therefore, Yuwen Wen politely declined the proposal of marriage between the two countries and made it clear to the envoys of the two countries: the princesses of the Great Zhou Dynasty were already married, while those who were not married were underage.

Such a decision may lead to the resurgence of war on the frontier, but Yuwen Wen is not afraid.

His army has begun to equip artillery and is still servile to engage in marriage. How cowardly would it be?

......

In the afternoon, Yuwen Wen finished the reception. After a short rest, he returned to the case and looked at a stack of information, then looked at the map, thinking about how to "train" Tuyuhun.

He rejected the other party's request for marriage, and the consequence might be that Tuyuhun raided the border, which was not a big problem for the Zhou army with artillery.

But I am not afraid of thieves not coming, but I am afraid of thieves thinking about it. Yuwen Wen thinks that if the Liangzhou General Administration is always harassed by Tuyuhun, how can the people live and work in peace and contentment? Where can I dare to go to the business and travelers?

The people, business and tourism are not at peace, the direct consequence is that the economy is bad, the agricultural and animal husbandry industries are not developing smoothly, and the number of households cannot increase, which means that there are not enough rents and transfers. The Liangzhou General Administration Office cannot support a larger number of garrisons, and can only rely on the court to continuously "transfusions" on blood.

The imperial court had to spend a lot of money. Yuwen Wen wanted to reduce the burden on the central government, planned to enhance the "hematopoietic function" of the Liangzhou General Administration, and racked his brains to find ways to develop the economy there.

In order to create a good "investment environment", we must find ways to solve the "difficult" problem of Tuyuhun. Although we are not done now, we must prepare in advance.

The officials he had just met were from the Liangzhou General Administration Office. This time he accompanied Tuyuhun envoys to the Central Plains, so Yuwen Wenshun met these local officials and listened to the other party's introduction to the situation in Tuyuhun.

Tuyuhun, whose founding monarch Murong Tuyuhun was named the country and clan name. Murong Tuyuhun originally belonged to the Murong tribe in Liaodong. After parting ways with his brother Murong Ting, he led his tribes to travel thousands of miles westward to settle in the Hehuang Valley (the land of Hehuang).

The Hehuang Valley refers to the area where the Yellow River and Huangshui River converge. It has fertile land and abundant water and grass. It is located on the west side of the eastern end of the Hetao Corridor and is the eastern gateway to the Qinghai-Tibet Plateau.

Murong Tuyuhun and his subordinates took root here, scattered branches and leaves, and stood firm.

The Murong Yan Kingdom (Former Yan) established by the descendants of Murong Wujiu has long been destroyed, and the country established by the descendants of Murong Tuyuhun is named after Tuyuhun and has survived to this day.

Tuyuhun's strength seems not strong, but since he can still live stubbornly until now, it means that his strength is not too bad.

The most important point is that it occupies a good place in Hehuang Valley.

In Yuwen's view, the territory of Tuyuhun was the Qinghai region in later generations, and its location in Hehuang was very important. The Xihai (Qinghai Lake), which produces a large amount of salt, was also under the control of Tuyuhun. Therefore, the economic strength of the Murong regime is still good.

The Hehuang Valley is really critical. In the future, it will be a key node for the Tubo invasion of Hexi Corridor and Longyou.

Therefore, it is best to control it in the hands of the Central Plains court.

The problem is that Tuyuhun looks delicious and doesn't seem to be difficult to eat, but after eating it in the stomach, it will be unable to digest it and will sooner or later vomit it out.

Tuyuhun's life span was very long in history. From the late Western Jin Dynasty, he lived until the Tang Dynasty. His national destiny of more than 300 years was much stronger than that of the Central Plains dynasty.

How did such a small country live so long?

The reason is very simple. Tuyuhun's vitality is tenacious, and like Luma, it hinders the master and has the "attribute" that defeats the sect leader.

When Tuyuhun emerged, the Fu Qin State (Former Qin) was in its moment of prosperity. The Qin army attacked the land of Liang State (Former Liang) and later took Qiuchi, which caused Tuyuhun next door to be shocked. He quickly sent envoys to send gifts to express respect in exchange for the Qin State's reward.

When Qin State was destroyed, another Qin State appeared. It was the Western Qin of Qifu clan, which seriously threatened Tuyuhun's survival. Tuyuhun quickly followed the routine and received a reward.

There were recurring times during this period, Tuyuhun was dissatisfied and was taught a lesson by the Western Qin Dynasty, and kneeled even more piously.

When the Western Qin of Qifu clan was destroyed by the Later Qin, Tuyuhun took the opportunity to occupy part of the old land of Western Qin, but was beaten to vomit blood by the restored Western Qin.

If you can't beat it, then kneel down. Tuyuhun followed the routine and paid tribute and saved his life. When the Western Qin declined, Tuyuhun took the opportunity to expand.

The Western Qin Dynasty was destroyed by Hao Lianbo's Xia Kingdom. After Tuyuhun, a yellow bird came to destroy the Xia Kingdom of Hao Lian's family, and offered prisoners of the Northern Wei Dynasty, and was granted the title of the Northern Wei Dynasty.
