My father, Li Shimin, requests Your Majesty to become the Retired Emperor.

Li Chenggan knew that Fuyu Long was lying.

However, upon further reflection, he realized there was no need to expose him directly.

Li Chenggan, with his hands behind his back and his head held high, paced back and forth in the hall, and slowly said, "Fuyu Long, there are some things I didn't want to say, but if I don't say them, they'll feel stuck in my throat, and I have to get them out."

"Your Highness, please feel free to speak your mind." Buyeo Long's expression became more respectful.

"First of all, you must understand a very simple truth: brotherhood is the most precious kinship in the world."

We must cherish our brothers.

Here are a few examples for you:

Back in the Spring and Autumn and Warring States periods, the crown prince of the State of Jin was Shen Sheng.

later,

Duke Xian of Jin favored Li Ji, and they had a son named Xi Qi.

Xi Qi wanted to become the crown prince, so he and his mother murdered Shen Sheng.

He believed that by becoming the crown prince, he could inherit the throne in the future.

After Duke Xian of Jin died, Xi Qi indeed became king as he had wished.

but,

Not long after, he was executed by his own ministers.

Hu Hai was not originally qualified to inherit the throne.

However, under Zhao Gao's instigation, he began to have improper thoughts.

He assassinated Fusu and became the Second Emperor of Qin.

but,

After he became emperor, he did not think about how to benefit the people, but instead thought about how to kill his own brothers.

He thought that after killing all his brothers, no one would be competing with him for the throne, and he could rest easy.

However, after the uprising broke out,

Xianyang was besieged, but no one came to the emperor's aid. In the end, he died at the hands of Zhao Gao.

Let's not talk about things from far away, let's talk about things closer to home.

The original crown prince of the Sui Dynasty was Yang Yong.

Although Yang Yong wasn't particularly outstanding, he didn't make any obvious mistakes either.

If he inherits the throne, he should have no problem being a ruler who maintains the status quo.

However, Yang Guang wanted to become the crown prince.

Therefore, he colluded with the ministers in the court.

Ultimately, he caused Yang Yong's death and became the crown prince himself.

After Emperor Wen of Sui passed away, he succeeded to the throne and became Emperor Yang of Sui.

After Emperor Yang of Sui ascended the throne, he had his own brothers Yang Jun, Yang Xiu, and Yang Liang all killed.

However, to his surprise, being an emperor was not so easy.

Due to years of locust plagues, insect infestations, and droughts, the Wagang Uprising broke out across the country.

Immediately afterwards, the Longxi aristocratic group, represented by Yang Xuangan, rebelled against the court and attacked Emperor Yang of Sui from behind while he was attacking Goguryeo.

Ultimately, Emperor Yang of Sui was killed in Jiangdu by his minister Yuwen Huaji, and so on. There are countless other examples like this.

History is like a mirror.

It's almost fair to say that anyone who turns against their own brother never ends well.

Unexpectedly, Yeon Gaesomun said after hearing this: "Li Chenggan, in my opinion, what you said is just a coincidence. According to you, didn't your father also kill Crown Prince Li Jiancheng?"

Does this mean your father won't have a good ending either?

Upon hearing this, Li Chenggan's heart trembled, because the cause of the Xuanwu Gate Incident was very complicated, and his father had been forced to do so.

However, Li Chenggan felt there was no need to explain these things to them: "Yeon Gaesomun, do you know that as a subject, you must observe the proper etiquette of a subject?"

"Was it really Gao Jianwu who sent you to the Wa Kingdom this time?"

"this--."

Yuan Gaisu was speechless.
