All the eunuchs from the East Palace were dispatched and conducted a carpet-style search in the East Palace. Li Er sat on the chair and waited for Kong Yingda, but there was no news about Li Chengqian. At the end, Li Er listened to the sound of "Your Highness of the Crown Prince" coming from the courtyard, and his patience was finally exhausted, and he slapped the table and stood up.

"Liu Bing, where have you died? Why don't you come here for me quickly?" Li Er said angrily.

At this time, Liu Bing was standing in the courtyard of the East Palace and talking to Zhang Nan. Hearing Li Er's roar, he quickly ran to Li Er.

"Liu Bing, the messenger started looking for me within the palace, but I still didn't believe it. Cheng Qian could run away? Without my warrant, he couldn't even leave the palace. He must be in the palace and searched for me." Li Er said angrily.

"Yes, yes, yes, villain will do it now." Liu Bing finished his greeting and prepared to leave.

"Wait, let me find Qianniu, who was guarding the gate of the East Palace this morning, and I have something to ask him." Li Er suddenly remembered something again and ordered.

Liu Bing bowed, and soon a Qianniuwei wearing armor came to Li Er.

"See the Emperor." Qianniuwei saluted Li Er.

"No need to be polite. I ask you, have the prince left the Eastern Palace today? I ask you to look at the prince. Have you ever left your post without permission?" Li Eryi asked glared at him.

Hearing Li Er say this, Qianniuwei quickly explained: "I didn't say anything to the emperor. The prince didn't even miss the face today."

"No missing face? This is strange. Why is Chengqian not in the Eastern Palace? Could it be that Chengqian can fly out?" Li Er said to himself. "By the way, fly!" Li Er was shocked. The Tang Dynasty is different from the past. If you want to fly out, Li Chengqian is really possible.

"Come on, go to the warehouse in the palace to see if the hot air balloon I reserved is still there." Li Erdao, the palace servant came to report soon and said that the hot air balloon was lying in the warehouse.

When Li Er heard that the hot air balloon was still there, he began to think again. Where did Li Chengqian go? Could it be that he would fly away from the sky and escape? After getting rid of this unrealistic idea, Li Er began to think about how to punish the unruly prince after he caught Li Chengqian. Now Li Er is angry.

But until the sun rose and time came to noon, Li Er still did not receive any news about Li Chengqian.

Zhang Nan was walking around in the yard, as if looking for something. When Li Er saw Zhang Nan's strange behavior, he was very puzzled and walked out and asked, "Qingquan, what are you wandering around? If there is nothing to do, I will follow him to find Cheng Qian's whereabouts."

The prince was lost. What a big deal. Why did Zhang Nan start to take a walk in the East Palace?

"I am looking for the emperor's words." Zhang Nan bowed his hand and said.

"The East Palace has been confirmed that Chengqian is gone, so what else do you want to find here?" Li Er asked.

"I want to know where the prince came from. Since I haven't gone out from the main gate, the prince must have used another method." Zhang Nan said while looking at the wall.

In the end, Zhang Nan saw footprints rubbing on the wall at the east wall, and Zhang Nan's guess was finally confirmed.

Li Chengqian ran over the wall. In fact, the inner wall of the palace was not very high. The outer wall of Chang'an City was very high. The inner wall of the palace, especially the walls of each palace, were not high, which was just over two meters. The height of the 400-meter barrier in the military academy was two meters high. The inner wall of these two meters above was really difficult for Li Chengqian, the prince who had been trained.

Moreover, when Zhang Nan saw the different eyes on the wall, Zhang Nan already understood in his heart.

Seeing Zhang Nan silent in front of the wall for a long time and began to stare blankly, Li Er asked, "Qingquan, do you have any ideas? Do you know where Chengqian has gone?"

Zhang Nan said with a wry smile: "Prince, the prince must have passed away by the wall."

"Have you run over the wall? Then where is he now?" Li Er continued to ask.

"I guess, Your Highness the Crown Prince should be among the 100,000 troops now. As for the army along the way, I don't know." Zhang Nan continued to smile bitterly, and in his heart he cursed Li Chengqian and said, "Li Chengqian, Li Chengqian, you are really brave. Now I can believe that you can do something to launch a coup."

"Why are you so sure that Chengqian must have left the palace? Without my order, Chengqian would not have left the palace. If you say that Chengqian can climb out of this wall, I still believe it, but if Chengqian can climb out of this outer wall, I don't believe it at all." Li Erdao.

"Your Highness the Crown Prince is determined to participate in this battle, and he must have been involved in the army. Needless to say, as for leaving the palace, I guess His Highness the Crown Prince should have gone out under the banner of your emperor," Zhang Nan guessed.

"Impossible, come here, please come and find the guards on duty in the palace today." Li Er obviously didn't believe that Li Chengqian could leave the palace without a warrant. But in the end, the guards on night shift at night finally proved that Zhang Nan was not wrong at all. Li Chengqian did go out under the banner of Li Er, and went out under the "notify the soldiers at the door in advance for the father's emperor."

The guards on duty did not dare to ask too much. After all, this was Li Chengqian, and today was the day for the soldiers to go to war. The guards let him go without asking him in detail. After all, he deceived people under the banner of the emperor, which was unexpected by the guards on duty.

"It's really a bastard. I'm so angry. Liu Bing quickly sent people to various troops to search. After finding Chengqian, he brought Chengqian back to me."

"Your Majesty, I think you may not be able to find someone you sent to find." Zhang Nan said with a smile.

"Why can't you find it? The 100,000 troops can be found one by one, just look at each other." Li Er asked.

"What the emperor said is, but how can the emperor guarantee that you can go to the prince with such a big fanfare, and the prince will not run away? He can even run out of the palace, let alone the camping army? Besides, the prince is not a person organized in the army at all, and it is impossible to investigate. Even if he hides, ordinary soldiers don't know him at all. So how can I find it? If I find it, I guess the army has already arrived in the grassland." Zhang Nan said.

When Li Er heard Zhang Nan’s explanation, he thought about it and found that it was really what Zhang Nan said. It was too easy to hide someone in such a huge military camp.

"Then you tell me, what should I do?" Li Er asked Zhang Nan.
