Because of this failure, Li Shimin did not rush to arrange again.

After all, with foresight, although the thunder punishment is powerful, Luo Cheng is not an easy person. He will never fall for it easily, and it will undoubtedly be a waste if he arranges it without certainty.

Although Li Yuan sent some thunder penalties to Li Shimin, they were also limited materials. Li Shimin can't afford to be too profligate, and in this situation, it is necessary for him to be careful.

The failure of the ambush made the generals look a little depressed, after all, this was a great opportunity. Now that it has failed, Yan Yun's army is even more powerful, which makes people extremely stressed.

Li Shimin naturally saw the reaction of the generals, Luo Cheng's record was so terrifying that everyone couldn't resist at all, but their morale was inexplicably low.

But this is not a way, no matter how the generals can't think of fighting with Luo Cheng, since they are in Tongguan at this moment, there is no other way to retreat, if there is no Li Shimin's order, it is obviously a certain death.

is thinking of escaping Tongguan, it is better to honestly obey Li Shimin's orders. Even if he couldn't beat Luo Cheng, he delayed the time as much as possible, and it was also meritorious.

Luo Cheng's army arrived at Tongguan, but did not attack rashly.

The generals were anxious in their hearts, so they came to ask Li Shimin how to deal with it. Although Li Shimin is the commander-in-chief, this battle is related to the danger of the three armies, and they cannot be ignorant of it.

Seeing the nervous and panicked look on the faces of the generals, Li Shimin knew in his heart, how could he not know his intentions, so he bowed his head and said: "Although the Yanyun army is strong, it is not invincible in the world. ”

"Now that we occupy Tongguan, we don't need to fight to the death, just delay as much time as possible. When the army is no longer able to support it, you can evacuate this place, and you need not worry. Li Shimin comforted everyone.

Although his words did not have any practical significance, the generals were still slightly relieved when they heard it. At least they don't have to fight the enemy here, and that's a good thing.

Seeing that Yan Yun's army was so strong, they were immediately terrified in their hearts, although there were people who were not afraid of death, but not all of them were like this. There are always people who think about their own safety.

Although Li Shimin explained that the generals were relieved, they were still worried and asked: "Now that Yanyun is menacing, and it is difficult for the army to stop the enemy, I don't know if the second prince can deal with it?" ”

When asked this, Li Shimin shook his head and said, "As you said, Yan Yun's army is extremely strong, and it is not so easy for us to deal with it, so we can only take one step at a time." ”

At this time, even if you brag, it's useless, I'm afraid that under Luo Cheng's strong attack, it will soon be revealed, and it is better to explain directly and decisively at this moment.

After everyone heard about it, the atmosphere was a little lower, but Li Shimin was so sincere that he still gave everyone some confidence. This second son has always been very strategic, maybe there is a turning point in this matter.

After worrying, Li Shimin quickly expelled all the restlessness in his heart, he directly led people to the top of the Guan Tower, and when he saw Yanyun's army from a distance, his face suddenly changed slightly, and his heart was shocked.

Slowly exhaling a breath of turbidity, Li Shimin was both helpless and a little emotional. He knew that Yan Yun's soldiers were strong, but he never thought that the three armies were all so elite, almost crushing the existence of Li Tang's soldiers and horses.

But now Li Shimin had no choice, he tightened his gaze, looked a little dignified, and shouted: "The three armies are under martial law, and the enemy must not be allowed to take advantage of it. ”

Li Shimin's tone was extremely decisive, the war was about to break out, what else could he do? It is nothing more than a stable army, no matter what happens, to stabilize the front.

When the defenders heard this, their expressions immediately became solemn, Li Shimin was extremely strict in governing the army, and they had no doubt about his determination. Now they can only obey Li Shimin's orders, and they don't know how the situation will develop.

……

Li Shimin in Tongguan is paying attention to Luo Cheng, and Luo Cheng is also planning how to take Tongguan as soon as possible.

After all, Luo Cheng had made arrangements before, and attacking Tongguan at this moment could be applied.

But when planning to tackle key problems, Luo Cheng did not gather others, but only with Xu Maogong.

After all, such a strategic matter, it is not reliable to find others, and it is still necessary to rely on Xu Maogong. With the help of his art of war, Luo Cheng's military strategy is also much stronger.

"Now Li Shimin is sticking to Tongguan, although this city wall has already made means, but Li Shimin must also have investigated, and if he wants to use it, I'm afraid it is not so easy." After thinking about it, Luo Cheng said in a deep voice.

When Xu Maogong heard this, his expression was calm as usual, and he said to Luo Cheng: "Even if Li Shimin can find clues, it is impossible to repair the entire wall, at most it is just to reinforce. ”

Hearing this, Luo Cheng nodded slightly, and showed a thoughtful look again. Maybe Xu Maogong already has a countermeasure, but he can't think about nothing, he still has to use his brain.

In fact, as Xu Maogong guessed, after Li Shimin attacked Xiatong Pass, he vaguely noticed that something was wrong. But he didn't know where the feeling came from, and he was in a trance.

Therefore, Li Shimin sent people to strengthen all sides of Tongguan, but he did not find Yao Ping's arrangement of the wall. As long as the offensive is fierce enough, this wall will not last long and will surely collapse.

It seemed that Luo Cheng was deliberately considered, Xu Maogong slowed down for a while before continuing: "If you want to successfully break the wall, the prince doesn't have to do it from the outside, you should break it from the inside." ”

Luo Cheng said with deep sympathy: "Although Luo Cheng has brought trebuchets and other equipment to Tongguan in this battle, it is not yet time to use it at this moment, if you lose the opportunity, it will be difficult to have miraculous effects." ”

Xu Maogong naturally knew what Luo Cheng meant, and the existence of gunpowder could not be exposed. Such weapons must be used at the critical time to achieve miraculous results.

If it is used in Tongguan, it will be much more difficult to attack Chang'an at that time, and Luo Cheng will naturally have some arrangements. The most important thing now is to find a way to take down Tongguan.

Xu Maogong pondered for a moment and continued: "If the prince attacks Tongguan with an elite, Li Shimin will definitely not sit still. Like before, gunpowder will not continue to be hidden. ”

"As long as it can be forced to use gunpowder under the defense of the city, such a big momentum will inevitably make the wall frustrated again, and when the time comes, with the help of throwing stones, it will be easy to break the pass." Xu Maogong said suddenly.

Luo Cheng nodded slightly, he understood what Xu Maogong meant, as long as he used the catapult, it was enough, and the gunpowder and the like should be left to Chang'an City, Xu Maogong's words were all here, and the strategy was out.

Thinking about this, Luo Cheng nodded and got up, and said: "What the military advisor said is very true, as long as Li Shimin is induced to use gunpowder, there is no need for us to bother with it, it is really a clever plan." ”
