Luo Shixin was looking forward to the coach's order to siege the city every day, but this order was unwilling to come down, which made him extremely anxious. He paid out of his own pocket to hold a siege strategy competition among the soldiers with a bounty of 500 stag, so that the soldiers could all participate in the advice. He actually hoped that this kind of competition would change the coach's will and thus issue a siege order.

Luo Shixin hurriedly said: "There are indeed many good ways, and it is easy to break through the city."

Although Zhang Xuan did not want to conquer the city, he was very interested in Luo Shixin's idea of ​​taking the mass line, so he smiled and said, "Give an example!"

Luo Shixin was excited and thought for a while and said, "Soldiers proposed to attack with fire and throw a large number of flammable objects into the city with a catapult. After igniting the fire, the city was burned. Then we attacked the city at the top of the city and there was basically no obstacle."

"What else?"

"Some soldiers proposed poison smoke schemes, using the east wind to burn poisonous branches in the upper wind direction to produce a large amount of poisonous smoke, causing the city to be covered with poisonous smoke."

This reminded Zhang Xuan of the poison smoke scheme used by Lai Hu'er when attacking Beishe City. It was estimated that the soldier also participated in the battle. He smiled and asked, "What else?"

"There are also soldiers who have been infected with the disease and throw the body of the disease into the city. In less than ten days, the Goguryeo soldiers in the city will die."

Everyone laughed and said, "This strategy is too vicious, it is simply a desperate plan. And if you forget that your army will get sick, killing three thousand enemies will hurt you by yourself, which is too loss."

Pei Xingyan next to him smiled and said, "Old Luo, tell me a few more reliable strategies."

Luo Shixin disturbed his head, "Then I will talk about three strategies to win the bounty!"

Everyone was interested and surrounded him and said with a smile: "Let's talk about the strategy of getting a bounty."

"The first one is the method of piled soil!"

Luo Shixin pointed to Tushan and said, "Tushan is only five feet away from the city wall. We can continuously pour soil down the mountain, and then the soil will soon accumulate on the top of the city, and we can directly kill from the mountain to the top of the city."

Everyone nodded. This plan is more reliable and the effect is very good. No wonder he can win the reward. Zhang Xuan was also a little moved and asked with a smile: "What about the second and third ones?"

"The second thing is to use fire to burn. The bricks of Yancheng Wall are made of stones. The walls are burned red with fire and then poured with cold water. The bricks will immediately crack and collapse. I have done experiments and the effect is really good."

Zhang Xuan pondered for a moment, not discussing the plan, and he said again: "Let's talk about the third plan."

Luo Shixin smiled and said, "The third strategy was the idea of ​​a local soldier. He won 300 stagnant coins. I think it can be implemented."

He pointed to the White Wolf Water several miles away from the north, "We can use the White Wolf Water to flood Yancheng. Have you noticed that Yancheng is located in a low-lying place. I heard that the old Yancheng was flooded after several consecutive days of heavy rain. If we dig the Bailang Water River embankment, Yancheng will be flooded. Even if we cannot submerge the whole city, most of the food will be destroyed."

"What a clever plan!"

Du Ruhui next to him couldn't help but praise: "This method is completely feasible. From the terrain, Yancheng is in a depression and is easily flooded. And what's more coincidental is that I carefully looked at Yunse. There was indeed heavy rain in Liaodong in recent days. After it rained heavily, and at the same time, the Bailangshui River embankment was dug, Yancheng would be finished."

Zhang Xuan pondered for a long time and finally nodded slowly, "This method is feasible!"

The White Wolf Water originates from Yanshan Mountain and flows eastward. There are many water sources along the way and the flow is extremely large. It is the second most important river in Liaodong area besides the Liaohe River. The White Wolf Water crosses Liucheng County, flows into Yan County and then turns southward to Yancheng North and finally flows into the Bohai Sea. Yancheng is located at the turn of the White Wolf Water.

Because Yiwulu Mountain is heading north and south, Yancheng is located in a low-lying place several miles away. More than 40 years ago, Yancheng was flooded due to continuous heavy rain, causing the White Wolf Water to burst the dam, killing thousands of people.

However, due to the long time, few people except the local elderly people have known the flooding history of Yancheng. Luo Shixin's reward for siege strategy finally made the local soldiers tell this past.

The next morning, the main force of the Sui army besieged the city of Sui crossed the White Wolf Water and evacuated northward. Cheers suddenly sounded from the top of Yancheng. Yuan Gaisuwen could not hide his inner joy and said to Yizhi Wende: "Is the Sui army forced to retreat because of insufficient food?"

But Yizhi Wende was always steady. He shook his head and said, "The Sui army has no reason to retreat. They are luring us out of the city and then annihilated us on the west bank of the Liaoshui River."

Yizhi Wende couldn't help but sigh again, "What's the point of even if we kill to Liaoshui? There is not even a sheepskin raft across the river."

The joy that Yoon Gaisuwen had just felt was extinguished by two words from Eji Wende. He stayed for a long time and said viciously: "It would be better to fight to the death, which is better than being trapped in the city!"

He turned around and walked towards the west wall. As he walked, he shouted to the soldiers: "Go and level the earth mountain!"

That night, it started to rain. The rainy season was the turn of spring and summer, but the rain came particularly fiercely, with lightning and thunder, and heavy rain, and the rain continued for two consecutive days.

The Sui army was stationed on the north bank of the higher Bailang Water. The large tent stretched for more than twenty miles and was very spectacular. However, the heavy rain for two consecutive days also made the Sui soldiers live like their New Year. The bedding and clothes in the large tent were wet, and there was an unpleasant smell in the large tent. It was very uncomfortable to sleep. Moreover, the soldiers could not leave the tent, so it was boring to stay in the tent.

That morning, Zhang Xuan came to the bank of the White Wolf River with dozens of generals. The rain had become smaller, but the raindrops were still very dense. Zhang Xuan and the generals were wearing straw hats and standing on the high slopes to look at the White Wolf Water.

The white wolf water is about twenty feet wide and has a high terrain. Due to the rain for several days, the water is turbid and the water flows very fast. From a distance, Yancheng is indeed located in a low-lying place, and it has already flooded its calves just after rain. At this time, Xu Shiji said on the side: "Master, it's not enough to dig the river embankment in the north. You must also dig the river embankment in the east. When you release water on both sides, only the city wall is left."

Zhang Xuan looked for a moment and turned to Luo Shixin and said, "This is your plan, you can complete it! As General Xu said, dig the mouth from the north and the east at the same time, and the time will be tonight."

Luo Shixin was overjoyed. He finally waited for this moment and quickly clasped his fists and said, "I am humble and obey the order!"

At night, it started to rain heavily again, and gloomy dark clouds covered the earth, making the night particularly dark. Lightning followed by lightning illuminated the riverbed of the White Wolf Water. There were countless Sui soldiers standing on the riverbed, holding a large shovel in their hands and digging the soil. The river water roared and rolled with white foam, which seemed particularly surging under the lightning.

Yancheng, several miles away, was still very quiet. The inside and outside the city were pitch black. The torches inserted on both sides of the city gate were extinguished. Half of the earthen mountains outside the west city had been cut off, and mud and water were flowing in the gullies.

Nearly a thousand Goguryeo soldiers patrolled back and forth on the top of the city, vigilantly paying attention to the movement outside the city. Most of the soldiers in the city fell asleep. The rain kept the city from flooding to their knees for days, making life very inconvenient, and the soldiers were extremely tired.

Yuan Gaisuwen couldn't fall asleep, and he was patrolling the city walls. He was very anxious. The heavy rains lasted for several days and flooded the granary. At least 30% of the food was soaked in the water and it would soon become moldy. He wanted to talk to Yizhi Wende again. After the rain stopped, they had to break through. Even if they could not cross the Liao River, they could still go north and use the power of the Khitan to cross the Liao River.

At this moment, Yuan Gaisuwen suddenly heard a strange sound, just like the whistle of a strong wind blowing through the mountains and forests. Other soldiers also heard it and lay on the walls and looked out.

"General, it's a flood, and a mountain torrent has broken out!"

A soldier pointed at the city and shouted. At this time, Yuan Gaisuwen also saw the surging water flowing under the city. The water level rose rapidly and had already flowed through the city gate. Yuan Gaisuwen's scalp exploded. There was no such thing as a mountain torrent, but the white wolf water broke the dam.

He shouted badly and shouted, "Roll the alarm bell quickly!"

‘Dang!Dang!Dang!’ The alarm bell rang rapidly on the top of the city.
Chapter completed!
