Wei Zheng and Fang Xuanling nodded when they heard this, and Li Haochen began to talk about Li Shimin's sudden retreat of ten miles, and the two top strategists of the Tang Dynasty couldn't understand what happened to make Li Shimin do such an unreasonable thing. However, the two talked for a while and came to the conclusion that Li Shimin must have encountered something.

At this time, Li Haochen suddenly patted his head and said: "This has been marching for days, and I almost forgot about this matter, it should be like this!" ”

Li Haochen's sudden move surprised Wei Zheng and Fang Xuanling, and his later words directly made the two of them feel the fog cover of the clouds and mountains, and they couldn't understand what they meant.

Wei Zheng was afraid of losing his identity, although he was puzzled in his heart, he didn't say anything, and Fang Xuanling didn't have so many estimates, so he asked directly: "Marshal, what do you mean by this?" ”

Li Haochen only reacted at this time, glanced at the two of them, and saw that both of them looked at him with puzzled expressions, so he laughed and said: "Here's the thing, I expected that Li Shimin might raise troops a few years ago, so I arranged in advance for Zhang Han to take the trap camp to Tongguan to deploy in the name of military exercises. We don't need to think twice! ”

Wei Zheng and Fang Xuanling listened to all this arranged by Li Haochen in advance, and the heart that was still hanging just now was put down at this moment, but it was just a blink of an eye, Wei Zheng frowned and said: "Although the plan of the suspicious soldiers can scare Li Shimin and dare not act rashly, but you must know that Li Shimin has an army of 150,000, and there are only 5,000 soldiers in the trapped camp, Li Shimin only needs to let the army attack, this trapped camp can't resist at all, this military plan is useless, how can you scare Li Shimin away, so that he does not dare to act rashly, I don't think we can be blindly optimistic! ”

After listening to Wei Zheng's words, Li Haochen nodded and said: "What Brother Wei said is extremely true, but big brother, you only know one thing, you don't know the other, I asked Zhang Han, on the mountain near Tongguan, to prepare an ambush in advance, prepare more rolling stones and falling trees, hide in the grass, hide your body, and when Li Shimin's army passed, it was instantaneous, let the soldiers beat drums and shout, and at the same time threw all the rolling stones and trees down the mountain. In this way, with the cover of mountains and bushes, Li Shimin must not know the truth and reality, and dare not act rashly, his team will inevitably panic under this sudden ambush, and the best choice for temporarily withdrawing from the army, and at the same time, in this way, we can also tell Li Shimin that we have actually been prepared, so that Li Shimin will throw a mouse trap and dare not act rashly! Give us time to react. ”

After Wei Zheng listened to Li Haochen's explanation, a sudden expression leaked on his face, and he nodded again and again to praise Li Haochen's strategy, and the matter was just as Li Haochen guessed, Li Shimin's withdrawal was really related to Zhang Han's suspicious tactics.

Yesterday, Li Shi's militia Lintong Pass, I don't know if it was because of the obedience of the state capital along the way, or because he was overconfident, he didn't have any preparation at all, and marched directly to Tongguan, who knew that this team, just marched to the front of the mountain outside the Tong Pass, Zhang Han jumped out all of a sudden, and broke out, Li Shimin responded to the battle in a hurry, and these 150,000 soldiers were mostly recruits, and when they encountered such a thing, they directly became a pot of porridge, and they didn't listen to Li Shimin's command at all, Li Shimin had no choice but to take his personal guards to resist the attack on the mountain, On the other side, he hurriedly retreated, and Li Shimin suffered heavy losses in this battle, so he could only temporarily retreat and think about countermeasures.
