Qin Tian also supported the investigation of Duan Lun's rebellion.

After all, judging from Duan Lun's transportation of iron tools outside, he must have conspired with others.

Duan Lun was very worried that the matter would find out to the king of Huainan, but now in this situation, if he retorts, it will be tantamount to saying that he has rebelled, and if he bears the charge of rebellion, Li Shimin will kill him.

After thinking for a while, Duan Lun could only be silent and let them say that Li Shimin would investigate if he wanted to, and if he didn't investigate, he wouldn't investigate, anyway, he insisted that he didn't rebel.

At this time, the ministers were still talking about it.

Some shouted that they must investigate, and some said that Duan Lun was a rebel, anyway, it was very noisy above the main hall.

Li Shimin here, after thinking for a moment, shouted: "Okay, I will send someone to investigate this matter, put Duan Lun in prison, and wait for the matter to be investigated, and then send it out." ”

This kind of rebellion should have been eagerly sent to investigate, after all, for Li Shimin, it is too dangerous for someone to rebel, but now that the Tang Dynasty soldiers and horses are resting, if it is really found that the king of Huainan is rebelling, he will have to use troops again.

And the king of Huainan rebelled, and the other vassal kings were afraid that they were also ready to move.

Therefore, the best way at present is to stabilize the king of Huainan first, and then deter him, and then consider the problem of these vassal kings after he Li Shimin's soldiers and horses are trained.

After Li Shimin finished saying this, someone escorted Duan Lun down, and when Duan Lun went down, he kept shouting that he had been wronged.

And by this time, the matter was almost over.

But Gao Shilian was a little dissatisfied, and he stood up again.

"Holy Lord, since this matter has to be investigated again, then Duan Lun is detained, and Qin Tian should also be detained, he slandered and rebelled."

Gao Shilian was a little reluctant, but Li Shimin's eyebrows were slightly condensed: "Gao Aiqing thinks that Duan Lun is right to use troops against Qin Tian?" ”

"This ...... Holy Lord, Your Minister......"

Gao Shilian was speechless for a while, and at this time, Li Shimin was already a little impatient: "I believe in Qin Aiqing, he patrols the whole country instead of me, whoever does it to him is to do it to me, it is to rebel, I let Duan Lun investigate the rebellion is another matter, and Duan Lun is indeed rebelling now, which is another thing." ”

To do it to Qin Tian is to rebel.

Li Shimin's words have been made very clear, even if the rebellion of King Huainan is found, that Duan Lun must be a rebellion, and it is a real rebellion, but he, Li Shimin, doesn't want to deal with Duan Lun now.

King Huainan's affairs may still be useful for Duan Lun.

Gao Shilian suddenly understood what Li Shimin meant, he felt that it was a bit bad for him to make such a play, but now that the matter had happened, he had no choice but to quickly accept the order.

He is a little uneasy now, for fear that he will not be able to save Duan Lun, and that Duan Lun will break the jar and break it, and then confess his affairs.

In that case, you'll be in danger.

It's too dangerous to have too close contact with a rebel, or even make some deals.

The early dynasty was finally over, and the ministers were already hungry with their chests and backs, so after leaving the main hall, everyone hurried home.

Qin Tian was here, but he was called to the imperial study by Li Shimin.

"Holy Lord, is there anything wrong with calling the ministers?"

Li Shimin said: "Qin Aiqing, tomorrow you will go to the East Palace to teach the prince." ”

Qin Tian thought that Li Shimin came to him for Duan Lun's matter, but he didn't expect it to be for Li Chengqian, Qin Tian smiled lightly and said, "Take the order." ”

"The prince now has some deviant behavior, which makes me very worried, so after you go to the East Palace, you must discipline him well, here I will give you a ring ruler, the prince can do anything that makes you unsatisfactory."

This ring ruler is not an ordinary ring ruler, but a ring ruler that can be used to beat the prince.

This is a bit similar to beating the king with a whip or something like that, you can beat the king unconscious, and you can beat the traitorous minister.

Of course, the ring ruler that Li Shimin gave Qin Tian could only beat the crown prince Li Chengqian.

To put it bluntly, it is to let Qin Tian discipline Li Chengqian well, and he doesn't have to care about Li Chengqian's identity.

It's just that in the face of such a ring ruler, Qin Tian is a little tangled, it stands to reason that with a ring ruler, he can indeed teach Li Chengqian casually, but Li Chengqian is the prince, if he becomes the Son of Heaven in the future, then what he taught him, will he hold a grudge for the rest of his life?

Li Shimin is simply cheating him by doing this.

But now he couldn't refuse this ring ruler, so he could only quickly take it.

After the two ministers said something about the crown prince, Qin Tian turned around and left the palace.

It was early spring, and the wind in Chang'an City was still cool.

Qin Tian rushed home with the ring ruler, thinking about how to teach the prince.

To be honest, he really doesn't know how to teach his children, after all, he has never been a gentleman, and he has to be a prince's teacher, if he doesn't teach that bit well, then it's all his own fault.

And, in the history of his time and space, Li Chengqian did not become the Son of Heaven in the end, and in case Li Chengqian here did not become the Son of Heaven either, and even rebelled, then what should he do as the prince?

Teach Li Chengqian well, what will the development of the Tang Dynasty be, maybe there is no Wu Zhou usurping the Tang Dynasty, right?

At this moment, Qin Tian's heart was really a little entangled, and he didn't know what to do.

During the Chinese New Year, Empress Changsun came to him to talk about this, and he didn't feel anything, but now that he is really going to become the prince, he found that there are many problems, and if he is not careful, he will cause a lot of trouble to himself.

The ring ruler kept flapping in his hand, and Qin Tian returned to the house like this.

After returning to the house, Qin Tian told the Ninth Princess about the situation, and after listening to it, the Ninth Princess's expression sank slightly, and then she sighed again, and said: "When the prince was young, he was very smart and very endearing, but I don't know why, as he grows older, he has become more and more rebellious in the past two years, which is really a bit distressing. ”

For Li Chengqian, the ninth princess is still very optimistic, and her relationship with Li Chengqian seems to be not bad.

After she said this, she glanced up at Qin Tian and said, "Xianggong is a capable person, after you become the prince's teacher, you will definitely be able to pull him back, right?" ”

This is the expectation and wish of the ninth princess, Qin Tian saw the appearance of the ninth princess, and his heart suddenly felt a little touched.

"Your Royal Highness the princess, don't worry, since I am the prince's teacher, I must help him do what a prince should do."
