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

Fang Xuanling shook his head: "The past was the past, and the present is the present."

In this world, there are no permanent friends or permanent enemies, only permanent interests!

At that time, our common enemy was Li Jiancheng.

If we don't bring down Li Jiancheng and Li Yuanji, we'll all die!

The situation is different now.

Fang Yi'ai scratched his head: "Dad, do you think there's anything different now compared to back then?"

"I'll tell you a piece of history and you'll understand."

Back then, Xiang Yu and Liu Bang were ordered by King Huai of Chu to attack the Qin state to the west.

Their agreement was that whoever entered Guanzhong first would be king. Later, Liu Bang entered Xingyang first, but Xiang Yu was very dissatisfied.

Originally, Liu Bang intended to stay in Qin Shi Huang's palace and not leave.

However, on the advice of Zhang Liang and Fan Kuai, he moved out of the palace and stationed his troops at Ba Shang, with 100,000 soldiers.

Xiang Yu stationed his army at Hongmen, with 400,000 troops.

If Xiang Yu had followed Fan Zeng's plan and launched the campaign to destroy Liu Bei the following morning,

Therefore, Liu Bang was destined to lose, and Xiang Yu would become the ruler of the world.

However, Xiang Yu was a fool; he failed to see the situation clearly.

When their common enemy, the Qin state, was destroyed, his relationship with Liu Bang had already changed from allies to enemies; it was a fight to the death.

Liu Bang foresaw this beforehand, but at the time, Liu Bang was weak, so he went to the Feast at Hongmen.

At the Feast at Hongmen, Liu Bang flattered Xiang Yu profusely.

Xiang Yu spared him.

Later, when Liu Bang's power grew, he forced Xiang Yu to his death at the Wujiang River.

Now, Changsun Wuji and I also have this kind of relationship.

When Li Jiancheng and Li Yuanji were alive, they were our common enemy.

Once Li Jiancheng and Li Yuanji were eliminated, my relationship with Changsun Wuji changed from allies to enemies.

However, Changsun Wuji was also quite cunning.

He resigned from his official post, seemingly living a life of seclusion, but in reality, he was manipulating things behind the scenes.

He secretly supported Li Zhi.

Li Zhi was too young and had a weak personality. If he became emperor in the future, it would mean that he would have the final say in everything.

Only if we support Li Tai in seizing the position of Crown Prince and becoming Emperor in the future will our Fang family have any hope.

Do you understand this principle now?

Fang Yi'ai nodded, seemingly understanding but not quite: "Father, what you said seems to make some sense."

"Li Chenggan is different from them. He is exceptionally intelligent and brave, and he cannot tolerate any wrongdoing. If he becomes emperor in the future, how could you possibly manipulate him?"

In other words, the day Li Chengqian becomes emperor will be the end for our Fang family.

"Father, I understand now. In any case, it's all up to you. Whatever you say goes."

Fang Xuanling glared at him: "And your relationship with Princess Gaoyang is also a headache."

Princess Gaoyang was no pushover either. It's said that when Chang'an was besieged this time, she went to the Emperor and suggested that he open the city gates and surrender.

"Huh?" Fang Yi'ai was also taken aback. "This woman is really crazy. How could she do such a foolish thing?"

Your Majesty is wise and mighty. How can we hand over the empire that you have conquered with great difficulty to others?

Is this a joke?

Fang Xuanling picked up his teacup and took a sip: "As for those rumors, I'm too lazy to even talk about them."

In short, you must do everything you can to improve your relationship with Princess Gaoyang.

If problems arise between you two, it won't just be a problem between the two of you; it could even drag the entire Fang family into it, do you understand?

"Yes, yes, Father, you're absolutely right. I'll definitely pay attention from now on."
