Li Shimin's decree to transfer back the generals was soon issued from Chang'an.

After receiving the holy decree, the generals also led the soldiers supporting the border to return to Chang'an as soon as possible.

Even Cheng Yanjin, who was in Mobei, returned to Chang'an half a month after the holy decree was issued.

After Cheng Yanjin returned to Chang'an, he was summoned by Li Shimin as soon as possible.

"Qing is finally back."

Li Shimin looked at Cheng Yanjin with a little emotion.

To tell the truth, Li Shimin was very glad that the general he sent to Fengzhou was Cheng Yanjin.

Otherwise, if other generals went to Fengzhou, they were afraid that they would miss Li Yan, and they would never find out that Li Yan was their eldest son who had been separated for many years so early.

"Your Majesty, in this battle, the old minister is frightened!"

Cheng Yanjin has now returned to Chang'an, and naturally reverts to the bastard image he usually shows.

"Your Majesty, don't you know that this Li Yan's way of fighting is called a unique ......"

Cheng Yanjin began to broadcast the experience of the Northern Expedition to Li Shimin in his own unique way.

Cheng Yanjin knew that Li Shimin was most concerned about this Northern Expedition than Li Yan!

Therefore, Cheng Yanjin naturally knew how to describe it in order to cause Li Shimin's mood swings, and he specially deleted all kinds of useless experiences and directly began to brag about Li Yan's achievements.

"During the battle to defend the city in winter, the minister saw that this Li Yan was brave and fearless, and his Fang Tian painting halberd, which weighed one hundred and twenty-eight pounds, was even more ......."

"Later, His Majesty Shengming issued an order for the Northern Expedition, and Li Yan led 1,200 cavalry alone and went deep into the grassland......"

"When the minister arrived at the Turkic royal city, Li Yan was injured, and he didn't know that he had killed thousands of Turks, and the iron armor on his arms was torn......

Li Yan was covered in blood, and there was such a long wound on his arm, but he was unmoved, and the old minister vaguely seemed to see His Majesty's posture when he led the old minister to fight......

As an insider of Li Yan's identity, Cheng Yanjin didn't mind connecting Li Yan and Li Shimin when he talked to Li Shimin alone.

Such a unique way of describing made Li Shimin have a new feeling.

So......

Li Shimin regretted it even more!

He now feels like he had a brain problem more than half a month ago!

Why did he let Li Yan, his extremely outstanding son, go!

How could he agree to Li Yan's resignation!

Li Shimin couldn't wait to give himself a slap in the face, retract his a few days ago, and then arrest Li Yan back to the court, and then personally adjust his son's mental health problems.

"Enough, don't talk about it!"

In a mood of regret and irritability, Li Shimin slapped the table violently, startling Cheng Yanjin.

Cheng Yanjin hurriedly reviewed his description to see if he had said something wrong.

"Your Majesty, the minister is guilty!"

In the case that he really couldn't think of what he said wrong, Cheng gritted his teeth and directly confessed.

When Li Shimin heard this, he was directly stunned.

He was just about to give Cheng Yanjin a step down, saying that this wave of madness was his own problem, but Cheng Yanjin pleaded guilty.

"Tell me what your sin is."

So, Li Shimin, who didn't want to lose face, had no choice but to follow Cheng Yanjin's words.

"Your Majesty, Your Majesty...... Minister...... During the Northern Expedition, the minister should not have marched slowly, causing Marshal Li Yan to resist the Turkic army of more than 10,000 people alone for an hour, and was finally injured. ”

Cheng Biting Jin held back for a long time, as long as he found a reason casually.

To be honest, Cheng Yanjin still doesn't understand why Li Shimin is mad.

"In that case, I'll punish you for a month."

Li Shimin borrowed the slope to get off the donkey and ended the topic of his madness.

The conversation between the two monarchs and ministers was almost over, and Li Shimin waved his hand after a few regular greetings with Cheng Yanjin, signaling Cheng Yanjin to leave on his own.

"Wang De, send Lu Guogong out of the palace."

Li Shimin was still regretting Li Yan's affairs, which caused him to be irritable and wanted to stay alone, and even Wang De, an incomplete person, didn't want to stay by his side for the time being, so he casually found an interface and sent him away.

"Yes, Your Majesty."

As an old eunuch, Wang De knew that implementing the emperor's orders was the essence, so he decisively withdrew from the imperial study and followed Cheng Yanjin to send him out of the palace.

On the way, the more Cheng Yanjin thought about it, the more aggrieved he felt, and he always felt that Li Shimin's madness was a little wrong today.

"Princess, you are the old man next to Your Majesty, can you help me take a look, I said something wrong just now, so that Your Majesty suddenly went crazy?"

Cheng Yanjin could also see that his confession had little to do with Li Shimin's willingness to go crazy, so he could only choose to consult the old eunuch.

"Oh, Lu Guogong, don't embarrass me, the holy will can't be guessed."

Wang De doesn't have the courage to bite Jin, his skills for surviving in the palace have been carved into his bones, so he doesn't dare to "on-demand" important ministers at will.

Seeing this, Cheng Biting Jin took out a gold leaf from his pocket and stuffed it to Wang De.

"Eh, Lu Guogong, actually, Your Majesty has been in a bad mood for the past two days, and when Dingbei Hou faced the saint before, he didn't know what to think, so he actually resigned."

"Your Majesty doesn't know what to think, but you agreed!"

"To be honest, Your Majesty has regretted it a lot in the past two days."

Although Wang De was loyal to Li Shimin, Li Yan's matter was not a secret, and he still said a few words to Cheng Yanjin.

"Yes, I understand Lao Cheng."

Cheng Yanjin suddenly thought of Li Yan's strange appearance before leaving Mobei, and immediately understood the situation.

It turned out that Li Yan said that he would no longer command the army, but that was what he meant.

This kid quit at the age of nineteen!

No wonder Li Shimin was in a bad mood, and his feelings were that he hit the muzzle of the gun when he was blowing it.

"Isn't this a trick for my old Cheng?"

The corners of Cheng Jin's mouth pulled out a wry smile.

Maybe others don't understand Li Shimin's mood, but as a person who knows the inside story, Cheng Yanjin can still understand something.

"Eh, that's it, it's just a month's worth of money."

Cheng Yanjin shook his head, no longer thought about the royal affairs, obediently left the imperial city, and returned to his Lu State Mansion.

……

At the same time, in the imperial study, after Li Shimin was stimulated by Cheng Biting Jin, he completely lost the mood of reviewing and reading.

Anyway, today's most important recital has been watched, and Li Shimin allowed himself to wander for half an hour.

"After all, how can I do business, my child......"

"At the age of nineteen, he was named a wolf Juxu, could it be that he disliked the title of Marquis of Dingbei too small? Should I just make a prince of the country......"

"Yes, it must be that the knighthood is too small, my son must have great ambitions! I must find another chance for him to make a meritorious achievement! ”

"But, he's resigned......"

Li Shimin muttered to himself, his emotions kept changing, and his brain was faintly painful.
