"After the artillery battle of Taiyuan failed, how did you take it down?" Wanyan Wushu suddenly spoke, but he asked Balisu a question that he already knew the answer for.

"Lock the city!" Balisu didn't know that his idea of ​​withdrawing troops had been rejected. In addition, he was angry with Han Chang, so he felt a tightness in his chest for a while, but he could only respond.

"How to lock the city?" Wuzhu asked seriously.

"We will build another city outside the city to lock Taiyuan from all sides. Then, when the situation is settled and the city is out of ammunition and food, we will concentrate our main forces to capture the city..." At this point, Balisu couldn't help but hold his injured arm and lowered his voice to try to answer. "Fourth Prince, the method of locking Taiyuan can't be used in Nanyang!"

"Why?" Wanyan Wushu raised his eyebrows.

"Although we lost the battle in Taiyuan, we didn't lose to such an extent today. When we locked the city, the artillery carts in the city had no more stones to use, so we were able to calmly attack the city!" Ba Lisu continued in a low voice. "And now Nanyang's artillery carts are sharp, how can we lock the city under the enemy's artillery?"

"You can build the city outside the range of the artillery!" Han Chang suddenly interrupted.

"How big a project would that be?" Balisu felt it was getting more and more absurd.

"It doesn't have to be completely locked up," Han Chang replied calmly. "Just build some strong walls for the long term!"

"Does this mean to keep the city under siege for a long time?" Balisu suddenly came to his senses, but he looked at Wanyan Wushu again, because he had guessed that this was most likely the Fourth Prince's intention, and Han Chang was just responsible for saying it... and today's military meeting was also meant to subdue him.

"What do you think, General Balisu?" Wanyan Wushu did not say anything more, and Han Chang continued to ask. "After a long siege, when the city is exhausted and Marshal Talan leads his troops to gather, we can capture the city!"

"I don't think so!" Balisu answered simply.

"Why?" Han Chang continued to ask. "Taiyuan was also surrounded for half a year."

"Nanyang is really different from Taiyuan." Balisu sighed, but still faced Wanyan Wushu earnestly. "Fourth Prince, please think about it carefully... One is the supplies in the city. Taiyuan was besieged suddenly that day, and people almost cannibalized each other when the city was broken. Nanyang is the secondary capital of Song, and there will be no shortage of food and military supplies in the city; the other is the climate. Nanyang is different from Taiyuan. This place is almost at the Han River, and the ice will not freeze until the middle of this month. The place is humid and hot. If it is difficult to get down for a long time, when the weather gets hot next year, the soldiers will definitely be unbearable; the other is that there is a Song emperor in the city. With him, the morale will definitely be full! With these three things, plus the powerful artillery carts in the city, we can't fire the artillery. Even if Marshal Talan gathers troops, how can we break it?"

Wanyan Wushu was also a little shaken for a moment.

"Nanyang is indeed difficult to attack, but if this city can be captured, I'm afraid the blame will be on the Emperor of Song!" Han Chang lowered his head and thought for a moment, but his words were shocking, and even Wanyan Wushu frowned for a moment.

Han Chang was not vague and directly expressed his thoughts:

"Please think about this, Fourth Prince. The reason why Taiyuan was captured was partly due to the frustration of the people in the city after losing all the reinforcements. Now that the Emperor of Song is sitting in Nanyang, after a while, the troops from all over the country will not hesitate to come to Nanyang. By then, we only need to defeat the reinforcements one by one under the city, and then the people in the city will gradually become unstable, right?!"

When Wanyan Wuzhu heard this, it was as if the clouds had cleared and the sun came out, and Balisu was choked for a moment.

"As for besieging the city, I just thought about it. Just as General Balisu said, Nanyang and Taiyuan are completely different. We should not copy the same method, but do the opposite." Han Chang continued. "As long as we build camps in the north and west of the city, we can ensure that the war horses have a place to graze and the supplies are continuously transported. The rest of the east side will remain empty, and the south side can be completely opened up... It just so happens that General Chizhanhui has passed away and no more Wanhu are promoted. We can go directly to the north and be directly under the command of the Fourth Prince."

"I understand that there is a lack of one side, but why do you want to completely let go of one side?" Bali Su paused for a while, but couldn't help asking out of curiosity. "Isn't it to restore communication between the city and the outside world?"

"If we can't restore communication between Nanyang and the outside world, it will be useless!" Han Chang sneered. "If you want to surround the three sides and force the Emperor of Song to leave Nanyang, let alone how to annihilate the troops who come to support the emperor in the future, just now, we have to let the people in the city know the bad news, right? Otherwise, wouldn't he be sitting back and relaxing?"

"This is a strategy to attack the heart." Wanyan Wushu finally spoke, but he made up his mind while touching the short knife in his arms. "Balisu, you can't say that this strategy can't be tried, right?"

Wanyan Bali thought about it again and again, but could not refute it.
