Li Yunxing always felt that this incident was strange. Such abnormal behavior of the Xiongnu must have some connection with this war.

He thought for a long time and finally decided to recall the secret chess he had laid out to the capital.

We must prepare in advance. There are rebels in Jingzhou and the Huns are ready to move.

Li Yunxing could not place all his hopes on the Imperial City's Imperial Guards, he had to guard against being surrounded by multiple forces.

At this moment, the forbidden troops outside the door suddenly came to report.

"Report to His Highness the Crown Prince that someone wants to see you."

Li Yunxing looked at the mountains of official documents and felt that reviewing the memorials was already a very troublesome task, and he had to deal with all these overt and covert attacks.

"Who is visiting? If it is not important, let him go back."

"Reporting to His Royal Highness the Crown Prince, it is His Royal Highness the Fifth Prince."

Fifth Prince Li Fengke? Li Yunxing doesn't have any dislike for him.

I like to do some carpentry crafts every day, but...

Li Yunxing's eyes suddenly lit up.

The guards waiting outside the door did not hear Li Yunxing's reply for a long time, thinking that the prince did not want to see him.

Then he asked softly, "Your Highness, how can you send the fifth prince away because of your humble position?"

At this time, Li Yunxing came back to his senses.

"No, please come in, the fifth prince."

Li Yunxing asked his eunuch Jinxi to organize all the memorials.

He was the crown prince and had the right to review the memorials submitted by all ministers. However, Li Fengke was only a prince who had not yet established a palace. Even a glance at the contents of the memorial was enough to be beheaded.

When Li Fengke was waiting outside the door, he realized that he had made a big mistake.

After leaving the Cold Palace, he came to the East Palace in a state of confusion.

What can he do if he comes to the prince?

How dare the useless prince ask for favors from His Highness?

The fifth prince clenched his fists and began to pray in his heart, praying that His Highness the Crown Prince would not agree.

Then he can breathe a sigh of relief and continue to hide and be his own little tortoise.

However, the Imperial Guard came to write a letter, "Your Highness the Fifth Prince, Your Highness the Crown Prince invites you to come in and wait for you in the study."

Li Fengke's heart thumped, leaving now was impossible.

He timidly bowed to the imperial guards who came to inform him, showing that he understood.

Then he walked slowly into the East Palace, thinking about how Xiao Jiujiu should explain to His Highness the Crown Prince.

She told him directly that she wanted to ask His Highness the Crown Prince to free his mother's life.

Or should you just say that you came to see the emperor, sit down for a while and then go back directly?

After Li Fengke walked away, the Imperial Guards outside the door began to discuss quietly.

"Why is this fifth prince bowing to us? Is he out of his mind?" someone said softly.

The imperial guard who had just been responsible for delivering the message heard this and said with a cold face, "The fifth prince is willing to give us face, but do you really dare to climb up the pole?"

"Hey! Captain Luo, don't be angry, aren't we just talking casually?"

"It's not okay to talk casually. There are many people in this palace, and every word we say represents the face of His Royal Highness. Talking about the prince in private in the palace is a capital crime of beheading!" Luo Zipao said sternly.

Others had no intention of talking anymore. After all, they had witnessed the last incident in the East Palace.

Although what Luo Zipao said was unpleasant, the truth behind his words was correct.

The Forbidden Army returned to its previous solemnity and solemnity, guarding the safety of the East Palace with all its heart.

In the East Palace, Li Fengke was still thinking about how to tell the prince, but the distance of several hundred steps took almost a stick of incense.

When he walked into the study, he realized that the prince was drawing something on the desk and had no time to pay attention to him.

Jinxi, the eunuch in charge of ink research next to him, saw the fifth prince coming in and reminded him softly.

"His Royal Highness the Crown Prince, His Royal Highness the Fifth Prince has arrived."

Li Yunxing then raised his head and looked at himself, and Li Fengke was about to bow and resign immediately.

"Your Highness the Crown Prince, if I need anything, please..."

Because his voice was as low as a mosquito or fly, Li Yunxing simply ignored what he said.

"Fifth Emperor Brother, come up quickly and see how this painting looks like."

Li Fengke's words were interrupted, and he could only bite the bullet and approach the table again.

What is this painting... about?

The lines are crooked and the ink is spattered, making it really hard to see what it is.

Li Yunxing was originally very excited, but when he saw that Li Fengke's expression was not right, he was also a little confused.

"What? Can't you understand?"

Li Fengke was already timid, and thought that he had offended His Highness the Crown Prince by being so stupid, so he suddenly became stammering again.

"I, I..."

"Don't be nervous." Li Yunxing comforted him in a deep voice.

He himself felt that the painting skills were pretty good, but maybe Li Fengke didn't understand these chariots very well.

Li Yunxing turned to look at Jin Xi again, raised his eyebrows and asked him if he could understand?

Jin Xi was the same as Li Fengke. In fact, he didn't understand what the Crown Prince was painting at the beginning.

When asked by the prince, he could only smile with a smile that was uglier than crying, "Your Highness, my servant..."

Li Yunxing felt that his head was full of black lines. He could not understand such a simple and clear draft of a catapult!

Are your painting skills that bad?

It suddenly occurred to me that when I painted potatoes for Princess Zulia of the Dayue Kingdom in the Western Regions, she also looked confused.

Is it not that I haven’t seen it before, but that my painting skills are too poor?

Li Yunxing sighed.

When I picked up the drawing paper, I wanted to crumple it into a ball and throw it away.

At this time, Li Fengke suddenly stepped forward to stop him, "Your Majesty... Your Highness."

"What's wrong?"

"Brother Huang painted a catapult?" Li Fengke said hesitantly.

Li Yunxing nodded, and Li Fengke saw it. Sure enough, he was right!

"Exactly! This is the catapult that I have improved upon. It is more powerful and consumes less manpower."

Li Fengke really couldn't compliment Li Yunxing's paintings. He just looked at the crooked horizontal line, which seemed to be the rocker of a catapult.

But generally speaking, it was very different from the catapults he had seen before.

"Your Highness, how about I let my younger brother write the writing and you dictate it?"

Li Yunxing nodded, "Okay."

Li Yunxing then dictated the improved version of the catapult to Li Fengke.

In this dynasty, it is impossible for Li Yunxing to want to build rockets and cannons. After all, he is not a top student in physics, but he still knows about such trivial matters as improving catapults.

During the Mongolian and Yuan Dynasties, the trebuchet reached its peak in development. It once set up 5,000 turrets in one night, allowing the Jin people to break through the gate in one fell swoop.

Now that Li Yunxing has made this thing in advance, it can be regarded as an invention that is several centuries ahead of its time.

While listening to Li Yunxing's description, Li Fengke drew the shape of a catapult.

"His Royal Highness... I think this catapult can be improved."

"Oh?" Li Yunxing looked at Li Fengke in surprise, "But it doesn't matter."
