After seven years of fiefdom, Li Shimin asked me to return and become the crown prince.

"Report..."Your Majesty, there is a letter from the court!"

Bored Li Kuan was about to draw a microscope design. If the steam engine was the starting point of the industrial age, then the microscope was the turning point of the medical age.

But just when Li Kuan was thinking about how to increase the magnification, a clerk hurried in.

Li Kuan paused.

A letter from the court?

Didn't he just write a letter to the court a few days ago? Here comes another letter, and the reply is too fast, which caught him off guard.

When did he get so much attention?

But I think it should be a boast of his bravery.

Taking the envelope, Li Kuan opened it indifferently:

My son is brave!

You are worthy of being my baby tiger. Don't worry, I have begun to coordinate with the generals in the army. It won't be long before Cheng Yaojin, Duke of Lu, will go to Lingnan to guard Lingnan for you.

You can rest assured, and then you can return to Chang'an to recuperate!

"I wipe...Am I kidding myself?"

Li Kuan's heart skipped a beat when he saw the letter. Did his father have a change of heart? When did he treat him so well?

"Quick... bring paper and pen!"

Li Kuan hurriedly asked Zhao Xin to bring paper and pen. He couldn't let Cheng Yaojin come, so he began to write furiously:

"Your Majesty, I am concerned about you. I am grateful to you. But please don’t trouble Duke Lu. Thanks to my bravery, the chieftains of Lingnan have been defeated step by step. I think we can defeat them soon!

I am fine, please don’t worry!"

After writing, Li Kuan handed it to Zhao Xin:"Please send it to Chang’an as soon as possible within five days!"

Five days later, in Ganlu Palace, Chang'an City.

Li Shimin was discussing matters with several ministers. Recently, Tuyuhun often invaded Liangzhou, Shanzhou and other places, but each time they just plundered some villages and left, making the people miserable.

Every time they plundered the villages, they ran away. It was a waste of military strength to send troops to conquer them. Fang

Xuanling, Changsun Wuji, and several other ministers were a little worried and could not come up with any countermeasures.

At this time, a letter from Lingnan was delivered directly to Ganlu Palace. Li Shimin had notified before that letters or memorials from Lingnan could be delivered directly.

Li Shimin thought that Li Kuan should accept his fate this time and return to Chang'an City.

However, when he opened the envelope again, Li Shimin's face turned black again.

Bang!

"How unreasonable, how unreasonable, this kid Li Kuan is simply lawless!"

Li Shimin was so angry that he overturned his own imperial table. After venting his anger, he saw that the ministers were still there. He waved his hand and said,"Today's matter will be discussed another day. You can leave first!"

But when everyone left, he rubbed his head and said,"Dao Zong, Yao Jin, you two stay."

The ministers looked at each other, and only Li Dao Zong and Cheng Yao Jin were left.

"Your Majesty, calm down. His Royal Highness the King of Chu.."Li Daozong wanted to explain, but this time he didn't know what was written in the letter, which made Li Shimin angry in public.

"Look at what this kid said." Li Shimin threw the letter directly to Li Daozong and the other two, and asked them to read it.

After reading the letter, the two were speechless.

His Highness the Prince of Chu is determined not to come to Chang'an.

"Didn't he say that the Tusi would be defeated by him? Give him half a month. If he still doesn't come, Cheng Yaojin, you personally lead 100,000 troops to capture Li Kuan and bring him to me. Take paper and pen, I will write it myself!"

Li Shimin vented his anger. Although he said this, his tone changed after he put pen to paper:

"Kuan'er is brave. I will give you another half a month. If the battle is not over yet, I will order Duke Lu to lead an army of 100,000 to help you defeat the enemy and settle Lingnan!"

"......."

Outside the Ganlu Palace,

"Duke of Zhao {Changsun Wuji}, what happened to His Majesty?"Some ministers who were preparing to report on official business outside the Ganlu Palace heard Li Shimin's rage and did not dare to go in. Seeing Changsun Wuji coming out, they asked cautiously in a low voice.

Changsun Wuji smiled and said,"I don't know, but it should be the King of Chu in Lingnan who angered His Majesty. I heard about the hardship in Lingnan a few days ago, and the attacks by the chieftains and bandits made His Majesty furious. This time, it should be the King of Chu's poor handling, which aroused His Majesty's anger again!"

Naturally, Changsun Wuji would not say anything good about King Chu Li Kuan.

"So that's how it is. The King of Chu has no talent for commanding troops, so it's only right that he failed!"

"Leaving Duke Lu behind should be to prepare him to go to Lingnan to assist Li Kuan. Really, this King of Chu has never contributed a bit to the Tang Dynasty, but instead caused a lot of trouble for the court!"

"What a waste, no wonder he was sent to Lingnan since he was young!"

Changsun Wuji listened to the increasingly incoherent words of the few people, and said with a sullen face:"Be careful with your words!"

After that, he left Taiji Palace, but his face was somewhat proud.

Lingnan City, Chu Palace!

When Li Kuan saw the letter from his father, he wanted to cry but had no tears. Li Shimin's sudden concern caught him off guard. He was also planning to send Cheng Yaojin to lead 100,000 troops for support? If they came, wouldn't it be exposed?

"Your Majesty, what should we do next?" Zhao Xin also read the letter and looked at Li Kuan hesitantly.

Li Kuan was helpless:"What else can we do? Let's pack up and return to Chang'an in a few days...."

With determination, Li Kuan also began to write his letter;

"Thank you for your concern, Father. I have fought bravely in Lingnan and have already defeated the Tusi coalition. I will be back to Chang'an soon......."
