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

"The area surrounding the Tang Dynasty is not peaceful at present."

War could break out at any time.

For example, Zhu Di's three campaigns against Goguryeo failed to conquer it.

This glorious yet arduous historical mission will surely be accomplished in our lobby in the future.

This is the mission that Heaven bestowed upon the Tang Dynasty.

"If you are capable of both civil administration and military affairs, why would you fear not having the opportunity to distinguish yourselves in the future?" Su Wan said.

Fang Yiai praised, "You're absolutely right."

I have completely reformed my ways.

Strive to be a useful person to the Tang Dynasty.

Su Wan rested her chin on her hand: "What you're saying is useless; the key is your actual performance."

Changsun Chong thought for a moment, then said, "Crown Princess, what I'm worried about now is whether Father Emperor will spare us?"

"That depends on your luck."

night.

Zichen Palace.

Li Shimin sat at the desk, reading the Zizhi Tongjian (Comprehensive Mirror for Aid in Government).

Wei Zheng stood respectfully to one side with his hands at his sides.

However, recently, Li Shimin discovered that the Zizhi Tongjian compiled by Li Chenggan and others was also excellent.

In some aspects, it is described in more detail than the "Essentials of Governance from Various Books," with clear viewpoints and is very instructive.

Li Shimin also loved it dearly.

At this moment, Li Shimin put down the Zizhi Tongjian in his hand and looked up at Wei Zheng.

"My dear minister, I have a question for you."

"What is the problem? Please instruct me, Your Majesty."

When the Han Dynasty was first established, it implemented a policy of heqin (marriage alliance) with the Xiongnu. But was this policy actually beneficial to the development of the Han Dynasty?

Wei Zheng stroked his beard and said, "Judging from the situation at the time, the policy of marriage alliances played a positive role in stabilizing the relationship between the Han Dynasty and the Xiongnu."

Back then, after Emperor Gaozu of Han, Liu Bang, seized power, he was furious to hear that the Xiongnu were causing trouble in the north.

He then led an army of 32 to conquer the Xiongnu.

One of his ministers, Liu Jing, advised him against it.

If we go to conquer them, we will surely fail.

Liu Bang was unconvinced, thinking to himself that the Qin Dynasty had unified the six kingdoms.

The Qin army was known as a fierce and powerful force, yet they were still defeated by him.

Xiang Yu was even more extraordinary, known as the Hegemon-King of Western Chu, a war god who was invincible in every battle.

Didn't he also beat himself to the point of committing suicide in the Wujiang River?

He simply couldn't believe that the Xiongnu were that powerful. Could they be more powerful than the Qin Dynasty or Xiang Yu?

Therefore, Liu Bang believed that Liu Jing was too timid and afraid of trouble.

So he did not heed his advice.

What was the result of sending troops to attack the Xiongnu?

They were besieged by the Xiongnu Chanyu on Baideng Mountain for seven days and seven nights, and were almost surrounded and killed.

Later, Liu Bang adopted Chen Ping's plan and bribed Modu Chanyu's wife.

Maodun then released him.

It seems that Liu Bang overestimated himself and underestimated his opponent.

Wei Zheng shook his head and continued, "Liu Bang wanted to find four horses of the same color to pull his carriage, but he couldn't find any. However, the army of the Xiongnu Chanyu Modu..."

The east side is all black horses, the west side is all white horses, the south side is all blue horses, and the north side is all brown horses.

Their cavalry was mighty and powerful, controlling over 40 men.

It was then that Liu Bang realized the difference in their abilities.

After returning to Chang'an, he reflected deeply on his mistake and commended Liu Jing.

Li Shimin stood up and paced back and forth in the hall with his hands behind his back: "In that case, Liu Bang is still much stronger than Yuan Shao."

"When Yuan Shao was about to launch the Battle of Guandu, his strategist Tian Feng vehemently opposed it, saying that this was an unjust army and that they should not fight against Cao Cao. He believed that if they sent troops, they would surely be defeated."

Yuan Shao was furious, believing that Tian Feng was spreading rumors and sowing discord among the troops, so he imprisoned him.

Later, Yuan Shao indeed suffered a defeat. After returning, the jailer in the prison believed that Tian Feng would definitely be released. Why?

Because Tian Feng's calculations were quite accurate, everything was within his expectations.

However, who could have imagined how Yuan Shao treated Tian Feng?
