The fourth update is here, please give me some monthly tickets!

The letter of help from Wu Yu, the lord of Cangyan City, was sent to Gaimu City.

The city lord Yang Wanchun looked at it for a long time, and finally his eyes fell on the face of the sender. After staring for a long time, he suddenly drew his sword and stabbed the messenger to death with a sword.

"City Lord?" everyone exclaimed.

Yang Wanchun drew his sword, threw it aside, and said coldly, "Cangyan City has been lost. You can tell from this letter that the black-feathered dog thief has already surrendered to Sui, just like the Lord of Xuantu City Wen Shan."

The Goguryeo civil and military officials couldn't help but feel thunder rolling by.

"This Luo Cheng and the Sui army had just taken Cangyan City less than half a day after they had taken the Sui army?"

There are also people who said, "Don't Luo Cheng go to the new city? Why do you go to the Cangyan City?"

Compared with the important town of Xincheng, which is more than ten miles around, Cangyan is just a small mountain city, and its location is relatively remote, without heavy troops or a large amount of food, grass and weapons storage. Luo Cheng flew into a fictitious shot and ran to capture Cangyan City, which was meaningless.

Some people also think that Yang Wanchun made a wrong judgment.

Luo Cheng is very powerful, so how can he have such ability? He will take Cangyan City if he wants to seize Cangyan City? With his marching speed, he will be at most just at Cangyan City. Even if Wu Yu has no backbone, can't he be able to defend for a moment? He is not just waiting for Luo Cheng to surrender.

"City Lord, what if Cangyan City has not yet descended?"

Yang Wanchun sneered a few times, "Wu Yu is a timid man, who doesn't know? He is just a civil servant, and he doesn't know about the soldiers at all. Now there are only a thousand old men and weak people in Cangyan City. How can he defend? Another thing is that he and the Lord of Xuantu City Wen Shan are friends, and they have also been in the same school. If Wen Shan can surrender, Wu Yu will surely surrender."

"There is another one. If Wu Yu really hasn't surrendered, do you think that Luo Chengzhen is going to take an army of 10,000 to besiege Cangyan City, and Wu Yu still has the chance to send someone to a letter of help?"

"So, there is only one possibility. Wu Yu has surrendered to Sui. This letter of request for help is false. In fact, it is to lure us out of the city to help, and then ambush us halfway. I will never be fooled and pass the orders. Without my orders, no one will be allowed to go out of the city to rescue."

The officials looked at each other.

Especially the officers from Cangyan City, they felt that this decision was too hasty.

"Or what if we send our troops to inquire."

However, some have raised other concerns.

"The city lord, although there are few soldiers in Cangyan City, there are no large amount of food, grass and weapons. However, this mountain city was originally a detour to guard the Xuantu City from Xuantu City to the Xincheng. Although Gaimu City is strong now, when Cangyan comes, Luo Cheng will no longer be blocked by us. From Cangyan to Xuantu, it is only sixty miles away. Without passing through my Gaimu City, Luo Cheng occupied Cangyan City and could bypass our Gaimu City and attack the Xincheng directly. The grain road and the rear road are also smooth."

This is indeed a problem.

The role of Cangyan City is to guard this sideways. It can be said that if Gaimu City is the west gate of the new city, then Cangyan City is a northwest gate.

Although the door is still there, the side door has been opened.

Luo Cheng now has a large amount of food, grass and weapons from Xuantu City, and the mountain city of Cangyan City is almost in danger, and has also won an important passage.

"Cangyan City must be taken back!" an officer shouted.

But Yang Wanchun gave him a blank look.

"What to take? This season is not a good season for siege. What's more, Luo Cheng is now strong and strong. He relies on the mountain city to seize Cangyan City. Unless there are tens of thousands of people, then cut off the connection between Cangyan City and Xuantu City and surround him for a year or two, then let's not talk about regaining Cangyan City."

However, they do not have these conditions now, so it is actually nonsense to take back Cangyan City.

After all, it was difficult for Luo Cheng to seize Cangyan, but the problem was that Yuan Jiantu transferred the defenders of Cangyan City several times before. Until now, Cangyan City is not only weak and unable to defend, but also Xincheng, Gamu and other cities cannot support it, which gave Luo Cheng the opportunity to take advantage of it.

After thinking for a long time, Yang Wanchun had to say, "Now Gaimu City has lost its important role as the barrier of the new city. I plan to leave five thousand men to continue to station in Gaimu City. I will bring seven thousand men back to the new city to garrison. No matter what, the new city cannot be lost. If the new city is lost, then I will be completely unable to defend the northeast of Goguryeo Liao."

In Cangyan City.

Luo Cheng, Wei Zheng and others were studying the map.

"After Yang Wanchun received the letter, there were probably only three choices. One, he really brought troops to help Cangyan City, two, he couldn't see through it, three, he led his troops to reinforce the new city."

"Tell me, how do we deal with it?"

Siye still had a straightforward approach, "Wu Yu said that there are only three thousand defenders left in the new city. I think we can take a risk and attack the new city directly."

"It's too risky. Although there are few soldiers in Xincheng, the city is strong, the food is strong and the machinery is profitable. There are many people in the city. We can summon thousands of young and strong people to defend the city at any time. If we kill, we lack siege equipment. There may not be any good way for such a strong city. If Yang Wanchun from Gaimu City comes here, we will still suffer."

Luo Cheng doesn't like to suffer losses.

Sun Tzu's Art of War is a good military book, but in this military book, it actually does not talk about all kinds of strange strategies, nor does it mean that the weak defeats the strong and defeats the more. On the contrary, Sun Tzu's Art of War begins with calculations rather than strategies.

Grandson advocates that when fighting, you have to fight a regular battle. You should calculate more before fighting, first calculate how much winning rate there is, how to improve the winning rate, and then fight when the winning rate can reach a certain level. If the winning rate is too low, then don’t fight.

I always think about taking a different approach to the sword. Although there are times when I succeed occasionally, I still fail more often. Now it is not a last resort. Luo Cheng, who has tens of thousands of people, will not easily put himself in that dangerous place.

"We should wait until the arrival of important cities in Xincheng, Liaodong, and Fuyu. We are just vanguards and are not here to attack the toughest, so there is no need to take this risk."

Wei Zheng spoke out, "Gaimu City may come to support Cangyan or guard the new city, so there is a high chance of leaving the city. We may be able to intercept and ambush on the road."

However, Cangyan City is north of Gaimu and the new city is east of Gaimu. This ambush can only be chosen one of two.

"Who do you think if Gaimu City sends troops, which side would you choose?"

"It's hard to say, if you don't go out, you can go out of Cangyan or Xincheng."

"But if we ambush, we can only choose one of three, and it is impossible to ambush three ways."

It's dark.

Sancha River Camp.

Yuwen Cheng was back with a frost on his face.

"Entertainment Father."

"Chengdu is back, what's going on with Luo Zhe? But he returned without success?"

"Returning to his adopted father, Luo Cheng led his army to the city of Gaimu. As a result, Gaimu City was prepared for a long time. Luo Cheng sent troops to attack the city, with more than a hundred casualties and he was defeated without success."

When Yu Wenhuaji heard this, he laughed, "I have known for a long time that this Luo Thief really thought he could do everything. He is always at a disadvantage now, hahaha."

Yuwen Chengdu waited for him to laugh enough before he said, "After adoptive father, Luo Cheng failed to succeed in Gaimu City, he led his army around Gaimu to go deeper. Then, he turned north and raided Cangyan City. The Lord of Cangyan City opened the city and surrendered. Luo Cheng's troops captured Cangyan City without bloodshed, and now the entire army is stationed in Cangyan City."

The laughter came to an abrupt end.

Yu Wen and his face were terrifying, with their eyes wide open.

The next moment, Yu Wenhua and he began to smash things in the tent like crazy, hysterically.

"This is impossible, this is impossible, this is impossible!"

"Entertainment Father!"

Yuwen Cheng waited for him to vent his anger before he went over and hugged him.

"I'm losing troops and generals in Dadonggou. It's okay if he came here to pick up the bargain and grab the merits. Why should he seize another city now? Why?"—
