After a big battle, it can be determined that under the strong impact of Li Yuanba, this wave of enemy offensive was successfully repulsed.

But Li Shimin did not have the slightest sense of relief on his face, and in the face of an attack by the enemy, they almost had to go all out. This is not what Li Shimin wants to see.

If it continues like this, I am afraid that if it lasts less than a day, Tongguan will be taken by the enemy. Coming to close the upper floor, Li Yuanba's role cannot be fully revealed.

Li Shimin knows very well that Li Yuanba's personal combat power is extremely strong, in fact, he is now subject to many restrictions and cannot fully display it. After all, there is no sideways push on the battlefield.

Faced with the dilemma at this moment, Li Shimin fell into contemplation, if Tongguan was broken too quickly. The enemy army can approach Chang'an unexpectedly, what a familiar plot this is.

Recalling last year, Luo Cheng won Tongguan with lightning speed. Then the army approached Chang'an, suppressing Li Yuan so much that he did not dare to fight, and he left only after taking the limelight.

Li Shimin naturally didn't want Tongguan to be lost, let alone let the previous plot happen again. Fortunately, he still has a turning point, as long as he can make good use of the thunder penalty, he may be able to save the decline.

But do you really want to use it now?

Li Shimin fell into deep thought, there is no doubt that the thunder penalty is their strongest hole card. Once it is used at this moment, how should we deal with the next big war, wouldn't we just have to sit back and wait?

After thinking about it, Li Shimin suddenly became helpless, it was really not that he didn't want to solve it. It's really that Tongguan's situation is too embarrassing now, and it can't play much role at all.

Although Tongguan is a key checkpoint for entering Chang'an, it is indeed an easy place to defend and difficult to attack. But this is just for ordinary soldiers, this Yanyun army is too terrifying.

Originally, Li Shimin thought that Luo Cheng would gather all the people to oppose the king, and another wave of alliances would attack. But he never thought that Luo Cheng would completely abandon external forces and only use Yanyun's elite to reach Tongguan.

In the face of such a strong army, Tongguan's advantage has been lost. With such a posture of looking at death as home, they have already broken through several layers of defense, and their physical fitness is stronger than that of ordinary soldiers, so it is not a problem to kill at the juncture.

If it weren't for Li Yuanba's action, I'm afraid Tongguan would really not be able to take a blow. Not to mention this place, even if Li Yuan makes proper arrangements, Chang'an, which has many arrangements, may not be able to hold on.

When he had never seen Yanyun's army, Li Shimin was still very confident in his own army. Seeing the momentum of Yan Yun's army, the irresistible aura of slaughter was coming, and he knew how he was sitting in the well and watching the sky.

The previous speculation about Yan Yun was still too conservative, and they had completely fallen into the inferior.

It was Li Shimin who quickly made a decision, the war had come to this point, did he have any other choice?

If these thunder punishments are not used again, I am afraid that there will be no chance, and now they will take decisive action to deter the enemy's spirit, and may be able to delay for a few more days, after weighing the pros and cons, Li Shimin's eyes gradually condensed.

"General Du, immediately punish Guanzhong Lei." Li Shimin ordered directly.

Du You, who was not far from Li Shimin's side, was also sent here by Li Yuan to help in the war. When he heard Li Shimin's order, he was a little surprised, but when he saw the fierce might of the enemy, he understood what Li Shimin meant.

Du You didn't dare to delay, and hurriedly led people forward.

After a while, a team of strange things wrapped tightly in black cloth were brought up. These are the thunder punishments made by Li Yuan, although the power of a single is limited, but a wave of strong attacks is still extremely effective.

Just like the previous ambush, although it was unsuccessful, it showed its great might, which gave Li Shimin confidence in his heart. Otherwise, he would have to think about how to run away now.

It's really not that Li Shimin is too cowardly, but that the gap in strength is too great today. If they still forcibly guard the gates, they are just giving away people's heads, and they will not be able to play any role at all.

Seeing the thunder punishment coming, Li Shimin's eyes froze, these are all his hole cards. It's a shame that the last ambush had already consumed some of it, but it didn't achieve any results!

After pondering for a while, Li Shimin looked at Du You and said loudly: "The enemy's offensive is strong, and now we can only rely on thunder punishment, and later the enemy army will attack again, and General Du will light the thunder punishment." ”

This is Li Shimin's order, Li Yuan is not in Tongguan at this moment, his order is the first. Du You didn't have the idea of disobedience, so he promised to do it slightly, and he would not be dishonored.

Although the situation is urgent at the moment, Li Shimin has some expectations in his heart. He couldn't wait to see how much of a role the lightning punishment could play and whether it would achieve his goal.

It's just that Li Shimin never thought that the thunder punishment did play a great role in this battle. It's a pity that this effect is diametrically opposed to what he imagined, not only did it not help guard the pass, but it tricked them.

Outside Tongguan, Luo Cheng also led the generals to watch the battle.

Looking at the situation on the Guan Tower, Luo Cheng nodded thoughtfully and said: "Presumably, Li Shimin can't hold it anymore, and Fang Yuanqing has already achieved the goal of Liwei by killing Guan Lou." ”

"As long as one more wave of people is sent to attack, Li Shimin will inevitably make a move, this is a great opportunity."

After speaking, Luo Cheng turned back thoughtfully, looked at the general and said: "Li Shimin is ready, how is the catapult situation now, is there an accident?" ”

The general saluted Luo Cheng respectfully, and said: "Marshal rest assured, the catapult has been prepared, and as soon as the marshal's order comes out, it can be used to attack Tongguan." ”

Luo Cheng nodded slightly, and seemed to be relieved.

……

At this time, Luo Cheng's second wave of offensive began.

Pei Yuanqing is outside Tongguan, although he has not achieved much success in killing Shangguanlou, but being able to retreat with his whole body is already a goal, and whether the plan can succeed depends on the next charge.

As a reckless existence, Pei Yuanqing has always been stingy in charging into battle. He himself is not strong and does not like to plan strategies, so it is perfect to lead troops to tackle key problems as a pioneer.

Although they had only just withdrawn, after resting, they had to continue to brew a second wave of offensive. Compared with before, Luo Cheng had already ordered it, and it would be much more dangerous.

But Pei Yuanqing is not afraid, and his days on the battlefield are the most thrilling. Ordinary people are fighting for wealth with their lives, but he has long been rich and noble, just to pursue fighting and fighting.

Looking up at the enemy army that was still in full array, Pei Yuanqing was ready. Since this battle is dangerous, of course Luo Cheng will not let them die, and should deal with it as soon as possible.

The drums beat behind him, Pei Yuanqing knew that the time had come, so he did not hesitate to lead the army to kill, and once again fiercely pounced on the Tongguan, like a tiger descending the mountain.
