Zhang Nan and Liu Bing returned to the house and told Cui Yue that they were going to chase the army.

"Lang Jun, didn't you say that the emperor agreed that you would not go to the battlefield? Why do you want to go with it now? Cui Yue asked with a strange expression.

"That's right, but the emperor asked me to announce the decree, if I don't go, I can't do it, if I don't go, it will be a disobedience." Zhang Nan said with emotion, there is no way, people are under the eaves, they have to bow their heads, and what Li Er said is quite right, even if Liu Bing is sent to announce the decree, Li Chengqian may still not believe it, this task seems to be really necessary for himself.

"Then Lang Jun, when will you come back?" Cui Yue asked.

"After the decree is announced, I will come back, soon, it will be about three or five days, Yue'er, you don't have to worry." Zhang Nan said with a smile.

"Then Lang Jun, you have to be careful, are you going to leave now?" Cui Yue said worriedly.

"Yes, I'm here to tell you, I'm about to leave, it's okay, I won't go to the battlefield, I'm just going to make a decree." Zhang Nan said.

Cui Yue was also relieved when he heard Zhang Nan say this, after all, Zhang Nan just ran an errand in the past, and the army had just set out, and when Zhang Nan finished announcing his decree, the army had not yet reached the grassland, so Cui Yue was not particularly worried.

When Zhang Nan said goodbye to Cui Yue, Liu Bing took Zhang Nan to the outside of Chang'an City

"Master Zhang, our family will send you here, you can drive it yourself." Liu Bing looked at the airbag of the hot air balloon that had been inflated and said.

"Aren't you going with me?" Zhang Nan asked.

"Our family won't follow, the emperor didn't let our family go to announce the decree." Liu Bing said and sent Zhang Nan to the hot air balloon.

"Eh, let's be polite, come on." After Zhang Nan finished speaking, he pulled Liu Bingye up with his hand.

"Lord Zhang, you ......." As he spoke, Zhang Nan loosened the rope tied to the hot air balloon, and the hot air balloon slowly rose into the air.

"I see, the prince will not come back, so I will definitely stay, if I stay there, what will happen to this hot air balloon, so you follow me, if I stay there, you will get this thing back, don't tell me that you won't make it, you will definitely do it." After Zhang Nan finished speaking, he sat aside and signaled that Liu Bing could start manipulating.

"Eh, that's okay, our family will send you over, if His Royal Highness the Crown Prince is unwilling to come back, Lord Zhang will let our family come back." Liu Bing is also helpless, the hot air balloon has already taken off, so he can't jump off by himself.

"Don't worry, when it comes to doing what you say, if the prince is not in the middle of the army, we will have to look for it all the way." Zhang Nan said with a smile.

"Why is Lord Zhang so sure that His Royal Highness the Crown Prince is in the middle of the army? If His Royal Highness the Crown Prince doesn't want His Majesty to find him, it is possible to go all the way to the army. Liu Bing asked while controlling the flight of the hot air balloon.

At this time, Zhang Nan's back appeared in his mind again, not that Li Chengqian's back was distinctive, but this person who had been trained in the military academy was still different from ordinary soldiers, and Zhang Nan guessed that the little soldier in black armor was Li Chengqian, so Zhang Nan flew straight to the middle of the army.

"Because...... That's my guess. Zhang Nan said with a smile, looking at Liu Bing's black line, Zhang Nan smiled even happier.

Flying all the way, Zhang Nan sat on the hot air balloon and looked at the snow scene below, which was a little interesting at first, but after watching it for a long time, it was all white, and Zhang Nan felt that it was not interesting.

"Liu Bing, why do you say that the emperor doesn't have a very good relationship with His Royal Highness the Crown Prince? It stands to reason that the prince is the eldest son. Zhang Nan thought about the father-son relationship between Li Chengqian and Li Er, and asked strangely, in fact, this is also Zhang Nan has nothing to say, it is too boring to sit alone, so Zhang Nan decided to gossip about things in the palace.

"This ...... Maybe it's because the emperor's requirements for the crown prince are too high. Liu Bing thought for a while and said.

"By the way, how come I've never seen any other prince? Is it so hard that they study all day? Zhang Nan continued to ask.

"Yes, all the princes of the emperor's age went to study in the Hongwen Pavilion, except for the prince who can study in the East Palace, the rest of the princes and princesses are studying in the Hongwen Pavilion, and the daily schoolwork is very heavy, and our family feels tired after watching it." Liu Bing looked ahead and said.

Hearing Liu Bing say this, Zhang Nan even understood why Li Er was a good emperor and not a good father, after all, children's nature is to love to play, but Li Er arranged so many courses for them, and Li Er himself was also very busy, and it was impossible to accompany his children every day, so it was understandable that these children were rebellious, just like the real Li Chengqian in history, as well as Princess Gaoyang, Li You, Li Su and others, needless to say, it is simply a waste of waste.

Then Zhang Nan quietly inquired about the secrets in the palace, and finally listened to a lot of gossip, Liu Bing didn't want to say anything, after all, if you say too much, you will die, Zhang Nan looked unfinished, who said that only women like gossip, if this man gossips, but he is more powerful than women.

The hot air balloon flew until dark, and Zhang Nan finally saw the army of fiery dragons in front of him.

"Quick, Liu Bing, hurry up and fly over, it's going to be there soon." Zhang Nan urged, and Liu Bing flew towards the middle of the army in a hot air balloon.

Seeing Li Jing and Wei Chigong sitting on their horses and walking forward, Zhang Nan and Liu Bing had already flown to the top of their heads.

"Huh? Brother Yao, did you hear any strange noises? Yu Chigong gouged out his ears and said. Although the hot air balloon flew quite high, the sound of the gas tank still attracted Wei Chigong's idea.

"Well, the old man heard it too, but why is this sound so familiar?" Li Jing stroked his beard, but he couldn't remember where he had heard this voice.

"You don't hear it like a hot air balloon." Wei Chigong thought about it and said.

Li Jing thought about it carefully, it was true, so he immediately gave the order to go down, and the army stopped advancing.

"Check immediately to see if someone has lifted the hot air balloon into the air without permission." Li Jing commanded to the herald beside him.

At this time, Zhang Nan and Liu Bing lowered the hot air balloon to a part of the height, and Zhang Nan lay on the basket of the hot air balloon and shouted loudly: "General Li doesn't need to look at it, it's me." ”

At this time, Li Jing and Wei Chigong could barely see where Zhang Nan and Liu Bing were.

Under the gaze of everyone, Zhang Nan and Liu Bing slowly fell into the middle of the army, as soon as Zhang Nan landed, he stepped out of the basket and said with a smile: "The two generals haven't seen each other for a long time." ”

When Wei Chigong and Li Jing heard it, their faces were full of black lines, where have they not seen each other for a long time, haven't they only seen it in the morning?
