A thousand-year-old family begins with one fighting against ten thousand.

Huang Yi's words silenced Zhang Chong; he really couldn't guarantee that.

"Send our deductions to my second uncle and ask him to check if anyone is betraying us."

After Zhang Chong finished speaking, he looked at Zheng Hu and said, "Uncle Hu, we need to investigate this place as well."

"Young master, you mustn't."

Huang Yi quickly stopped him.

"At this point, these are all just our speculations, and we shouldn't investigate them openly."

"Once this kind of thing is investigated, it will definitely cause panic in the military. Everyone will worry that there might be a traitor in their lives, and the combat effectiveness will not be able to be raised from 10 points to 5 points."

"Just remind General Zhang to be more careful. General Zhang is a veteran, so he naturally knows what to do."

"Just do as Huang Yi says."

Although Zhang Chong really wanted to find this traitor right now, considering the bigger picture, he decided to put aside his own feelings for now and wait until after the final battle to find this person and tear him to pieces.

"Uncle Tiger, those in charge of opening and closing the various city gates must be people with clean and trustworthy backgrounds, preferably old men who have followed my father in starting out."

Zhang Chong said to Zheng Hu.

Zheng Hu looked at Zhang Chong and Huang Yi with a somewhat dazed expression.

He seemed to see Zhang Huai and Huang Ce from the past, just like before, one offering suggestions and the other controlling the direction and making decisions, step by step leading them to where they are now.

He smiled with relief. "Don't worry, young master, I will arrange everything properly."

Many of the fellow villagers who followed Zhang Huai in his early days died in battle, but some remained active in the army and were deeply trusted by Zhang Huai.

These people were Zhang Huai's foundation and the least likely to betray him. Although most of them were taken away by Zhang Huai, some remained to assist Zhang Chong.

"Also, arrange for someone to send a messenger to inform Father of what has happened here as quickly as possible."

Zhang Chong arranged everything here methodically, while Huang Mo quietly provided guidance from the side.

Outside the city, where the imperial army was stationed, a resolute-faced figure looked up at Yunzhou City.

"Is everything ready?"

"Everything is ready. It will definitely liven up the entire Yunzhou City."

The man with the resolute face nodded. "Give the order, it will begin tonight."

"Here you go!"

The soldiers around him obeyed and left. The man shook his head, picked up a book from the table, and began to read. He didn't seem to care much about the war.

Just as the imperial order reached the frontier, unusual activity occurred on the border. A large foreign army was pressing in, preventing them from sending more troops south.

They knew this was to restrain them, allowing Zhang Huai and others to create more chaos in the Tang Dynasty and weaken its strength.

If, by any chance, Zhang Huai actually succeeds, it would be an absolutely fantastic thing for them.

They will only have a chance if China descends into chaos.

"A bunch of clowns."

The man shook his head, seemingly unconcerned about the impending war, as if the book before him was more important.

After all, this war was just a show from the very beginning.

The purpose was simply to force Zhang Huai and his men to return, so that the imperial court could allocate more troops to encircle and suppress them.

It doesn't need to be very intense; it just needs to look tragic and heroic enough.

In the man's view, such a war was simply a waste of his time. If it weren't for the commander offering him a military treatise as payment, he wouldn't have bothered heading south.

If Zhang Chong and Huang Yi knew that their battle of wits was just a battle against thin air, they would probably be so angry that they would spit blood three feet away.

Because the city had made thorough preparations, the Tang army's night raid was discovered immediately, and a large number of troops were mobilized to the city walls, ready for battle.

Zhang Chong and Huang Yi also got dressed early and came to the city wall, only to be completely dumbfounded by what they saw.

The Tang army, with only 5 men, actually divided into four routes and attacked from all four sides of the city wall, showing that they were determined to fight Yunzhou to the death and would not return until the city wall was breached.

Who besieges a city like this? It's never written like this in any book!

Zhang Chong and Huang Yi looked at each other, somewhat puzzled.

"Could this be a tactic to wear down the enemy?"

Huang Yi speculated, "The Tang army is attacking from all sides, and we will have to mobilize a large number of troops to defend. As a result, the soldiers will not be able to sleep well at night and will not be able to concentrate during the day. In the long run, they may be able to take advantage of the situation."

"Although the Tang army will also get tired, they are the offensive side. They have figured out that we are mainly on the defensive, so they dare not go out to attack. The initiative is in their hands."

"They could choose to send a small number of people to harass the enemy one night, while the rest of them conserve their strength and launch a full-scale attack during the day."

"Or they could rest during the day and launch a major attack at night when people are most tired, hoping to capture the city in one fell swoop."

"Well-reasoned and convincing."

Zhang Chong nodded. Zheng Hu was a reckless man who knew nothing about military strategy. He thought that Huang Yi, being Huang Ce's son, must be better than him in this regard.

Both of them agreed with Huang Yi's guess and went further and further down the path of outsmarting thin air.

"So what should we do?"

Zhang Chong asked.

Huang Yi stroked his chin, and late at night, he took out a folding fan from his pocket, opened it, and gently fanned himself. "I have a plan."

"What plan? Tell me quickly!"

Zhang Chong asked impatiently.

"General Zheng, how many men do you need at the very least to defend Yunzhong City?"

Huang Yi asked Zheng Hu.

"Although the enemy has 5 troops, attacking a city is different from defending it. We only need a portion of our forces, 3. With 3 troops, I can defend Yunzhong City."

"good!"

Huang Yi suddenly slammed the folding fan shut, startling Zhang Chong.

"Isn't the enemy just taking advantage of our reluctance to leave the city?"

"The troops left in the city are a military secret, and the enemy certainly doesn't know about them."

"For the past two days, we have pretended that there are only 30,000 garrison troops in the city to deceive the enemy, while the remaining 20,000 elite cavalry have been resting and recuperating."

"I'm afraid the enemy wouldn't have expected that we, as the defenders of the city, would actually be leading 2 elite cavalry."

"At that time, as long as we lead 2 elite cavalry out at the crucial moment and charge straight into the enemy camp, we will surely win a great victory by waiting in ambush."

"With 3 troops garrisoning the city, even if we fail, we don't need to worry about losing Cloud City."

"Brilliant, brilliant, brilliant! This plan is absolutely ingenious!"

Zhang Chong praised them, saying that the two young men hit it off immediately and decided to proceed with the plan.

Zheng Hu couldn't argue with that. In any case, 3 troops were enough to defend Yunzhou City, so it wouldn't hurt to let the remaining 2 troops try.

Thinking of this, Zheng Hu no longer objected and nodded in agreement to hand over the 2 elite cavalry to Zhang Chong.

"My lord, you must promise me one thing: you are absolutely forbidden from personally leading troops into battle. You must remain in the city to oversee the situation!"

Looking at Zheng Hu's determined gaze, Zhang Chong sighed and nodded in agreement.
