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

At this point, Zhang Zhongjian no longer cared about the lives of Li Yuanli's army.

"Retreat immediately!"

With his command, the army of Buyeo withdrew from Chang'an and engaged in fierce fighting with Li Chengqian's army that was coming towards them.

Li Chengan took the lead, shouting, "Zhang Zhongjian, where do you think you're going?"

Zhang Zhongjian realized that his side was now attacked from both sides.

He looked up and saw a colossal creature behind Li Chenggan's army that had almost completely destroyed the Iron Pagoda he had brought.

Zhang Zhongjian had no time to deal with Li Chenggan.

Seeing Li Chengan heading towards him, he turned his horse and rode away!

With King Zhang Zhongjian gone, who in the Buyeo army would risk their lives here?

As the saying goes, a defeated army collapses like a landslide; the Buyeo army fled, leaving behind thousands of corpses.

Li Yuanli's army was not so lucky.

Of Li Yuanli's 50,000 troops, several thousand were killed, and the rest surrendered.

Li Shimin and his son Li Chenggan, working together from within and without, achieved a great victory.

Someone brought up Li Yuanli, Li Fan, and Li Zhen, father and son.

Upon seeing Li Shimin, the three men knelt down.

His generals requested permission to execute Li Yuanli.

Li Yuanli lowered his head, and sweat beaded on his forehead.

Li Shimin looked at Li Yuanli with great pain: "What can I say about you?"

Because we are brothers, I trust and value you greatly, so I have sent you to Xuzhou to serve as governor.

Xuzhou is a vast and resource-rich area, and also a strategically important military location.

Think about it, among these brothers...

Who else gets such good treatment as you?

Li Yuanli didn't say a word. Then, Li Shimin said, "Father has worried himself sick for us. He had no choice but to invite him to the city wall to earnestly persuade you."

But you simply won't listen.

You treat your brother as an enemy, and Zhang Zhongjian as a good person.

What was the result?

You've been tricked, haven't you?

You're charging ahead, but they've pulled away your ladder.

Did they even care whether you lived or died?

Li Jing bowed and said, "Your Majesty, Li Yuanli colluded with Zhang Zhongjian, the King of Fuyu, to besiege Chang'an, causing our army to suffer heavy losses."

"Your Majesty, please issue an order to execute them, father and sons!"

Upon hearing this, Li Yuanli, Li Fan, and Li Zhen, father and sons, trembled all over.

Li Shimin, with his hands behind his back, looked up at the sky and sighed: "The pain of the Xuanwu Gate Incident is still in my heart and can never be erased."

My father is already old and frail; how can he bear the pain of losing his son?

Li Mao, Li Fan, and Li Zhen were all beloved grandsons of the emperor.

Now that Li Mao is dead, how can I bear to harm them?

"Alright then, imprison the three of them, father and sons, in the Dali Temple jail for now, pending my report to the Emperor for further action!"

"Your Majesty is wise!"

At this moment, warriors took Li Yuanli, Li Fan, and Li Zhen, father and son, away.

Li Chenggan approached, knelt on the ground, and said, "Father, I am late in coming to your rescue. Please forgive me!"

Li Shimin looked down at him, his face darkening, and asked, "Why have you been so late? Are you intentionally stalling for time, hoping to watch Chang'an fall?"

Li Chenggan crawled forward two steps on his knees: "Your Majesty, it is not that I do not wish to return."

When I learned that Chang'an was besieged, I was extremely anxious and wished I could fly to my father's side immediately.

However, the Yanqi army clashed with us.

Getting rid of them isn't so easy.

Furthermore, the journey to Yanqi involves traversing deserts, swamps, mountains, and rivers, making the roads rugged and difficult to travel.

Your son has finally shaken off the Yanqi army and is rushing back day and night without daring to slacken his pace.

After a hurried journey, we finally arrived in Chang'an.
