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

Li Chengan thought of his brother Li Tai, whom he both loved and hated.

Back then, Li Shimin launched the Xuanwu Gate Incident, killing Crown Prince Li Jiancheng and Prince Qi Li Yuanji, which became a lifelong regret for Li Shimin.

Although Li Shimin had his reasons for doing so, and was forced into it,

At that time, if he hadn't taken action, the entire Qin Prince's Mansion would have fallen apart, and civil officials like Fang Xuanling and Du Ruhui, as well as military generals like Cheng Yaojin, Qin Shubao, Li Jing, and Li Ji, would have all left him.

Li Shimin will also die without a burial place.

but,

Li Shimin personally killed his own brother, which was a lifelong regret for him.

People have many opinions about this, with many believing that Li Shimin was too ruthless and showed no regard for brotherly affection.

That time,

Li Chengan visited Li Yuan at Yong'an Palace and sensed that Li Yuan was deeply saddened and still harbored resentment over the Xuanwu Gate Incident.

What father doesn't love his child?

Li Chengan then recalled what his mother had once told him: brothers must get along harmoniously.

She had promised her mother that no matter what Li Tai did to wrong her, she would forgive him.

Li Chengan felt a chill run down his spine when he thought about how Li Tai had set traps to kill him on several occasions.

Li Chenggan did not want to end up like Emperor Wen of Han, Liu Heng, or Cao Pi, who could not even tolerate their own brothers.

at this time,

He heard that Buyeo Yong had been persuaded by Yeon Gaesomun to come to the Wa Kingdom.

Buyeo Long actually suggested to King Sumin that he kill his brother, Buyeo Pungjang.

Isn't that vicious?

That time,

When Li Chenggan was in Baekje, he already felt that Buyeo Long was not a good person.

In an attempt to kill himself, Fuyu Long nearly burned Fuyu Fengmei to death. Unexpectedly, this time, he turned on Fuyu Fengzhang. It seems he is the second Huhai.

Li Chengqian stared intently at Princess Tianyan: "Your Highness, may I ask what else they discussed? Did they reach any agreement?"

Princess Tianyan gently stroked her hair, her beautiful eyes turning to Li Chenggan:

"Your Highness, they also say that your Tang Dynasty's origins are illegitimate."

"What do you mean?" Li Chenggan frowned.

"They said that your grandfather and your father were both meritorious officials of the Sui Dynasty."

Moreover, your grandfather and Yang Guang were cousins.

It was because of this relationship that Emperor Yang of Sui valued Li Yuan and sent your grandfather to Jinyang to guard against the Turks. Unexpectedly, after arriving in Jinyang, Li Yuan used his power to recruit soldiers and expand his army, plotting rebellion.

Ultimately, Li Yuan raised an army and captured Chang'an, which was the fundamental reason for the demise of the Sui Dynasty.

In other words, your Li family is very unruly.

Taking advantage of others' misfortunes to plot against them, they have no sense of gratitude whatsoever.

The Western Regions countries respectfully address your father as "Heavenly Khan," but that was out of necessity.

Your father is ambitious and constantly develops military power.

It is said that the military strength of your Great Tang Dynasty surpasses that of any other dynasty in ancient times, and is far more powerful than that of the Sui Dynasty.

Your father is vigorously developing military power with the aim of annexing all the surrounding countries, including those in the Western Regions and the Eastern countries.

That naturally includes our Wa (Japanese) country as well.

Yeon Gaesomun and Buyeo Long were quite surprised to hear that an alliance had been formed between Wa and Yanqi.

finally,

They were willing to put aside all hatred and unpleasantness, form an alliance, and work together to deal with the Tang Dynasty.

They said, "Your father still loves you very much. If he kills you, the Tang Dynasty will definitely send troops to punish the Japanese."

"Including Baekje and Goguryeo, we'll take them all down together."

Li Chengan was speechless after hearing what Princess Tianyan said. It seemed that no matter how he explained, it would be useless. Perhaps in their eyes, the Tang Dynasty had always been about conquering the world.

Li Chenggan was also secretly surprised.

The alliance between Wa and Yanqi was already a headache enough, but unexpectedly, Goguryeo, Baekje and Wa reached an agreement to unite against the Tang Dynasty. Wouldn't that put the Tang Dynasty in a precarious situation?
