Li Yunxing always felt that this incident was strange, and such an abnormal behavior of the Xiongnu definitely had some connection with this war.

He thought about it for a long time, and finally decided to recall the dark chess he had laid before to the capital.

You must prepare in advance, there are anti-thieves in Jingzhou, and the Huns are ready to move.

Li Yunxing could not pin all his hopes on the forbidden army in the imperial city, and he had to be surrounded by multiple forces.

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

"Tell His Royal Highness the Crown Prince, someone asks to see you."

Li Yunxing looked at the mountains of official documents, and only felt that this batch of readings was already a very headache, and he had to deal with these open guns and hidden arrows.

"Who's visiting? If it doesn't matter, let him go back. ”

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

The fifth prince Li Fengke? Li Yunxing didn't have any objection to him.

I love to do some carpenter's skills every day, but ......

Li Yunxing's eyes suddenly lit up.

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

Then he asked softly, "His Royal Highness the Prince, will the five princes be sent away?" ”

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

"No, please come in."

Li Yunxing asked the eunuch Jin Xi to sort out all the folds.

He is the crown prince of the prison country, and he has the right to approve all the ministers' recitals, but Li Fengke is only a prince who has not opened the palace, and even a glance at the content of the recital is enough to be killed.

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

After leaving the cold palace, the ghost came to the East Palace in a daze.

What can he do when he comes to the crown prince?

The useless prince of waste, how dare he ask His Royal Highness the Crown Prince for favors.

The five princes clenched their fists and began to pray in their hearts, praying that His Royal Highness the Crown Prince would not agree.

Then he can breathe a sigh of relief and continue to hide back to be his own shrunken turtle.

But the forbidden army came to reply, "His Royal Highness the Fifth Prince, His Royal Highness the Crown Prince announced that you will go in and wait for you in the study." ”

Li Fengke sighed in his heart, it was impossible to leave at this time.

He was so timid that he bowed to the forbidden army who had come to pass the news, indicating that he understood.

Then he walked slowly to the East Palace, thinking about Xiao Jiujiu in his heart, how to explain it to His Royal Highness the Crown Prince in a while.

I told him directly that I wanted to ask His Royal Highness the Crown Prince to let his mother live.

Or do you just say that you will come to see the royal brother, sit down for a while and go back directly?

After Li Fengke walked away, the forbidden army outside the door whispered.

"What are these five princes bowing to us? Is he mentally abnormal? One said softly.

The forbidden army, who was in charge of spreading the word just now, heard the words and said with a cold face, "The fifth prince is willing to give us face, do you really dare to climb up the pole?" ”

"Hey! Captain Luo, don't be angry, aren't we 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 the Prince. The palace is talking about the prince in private, this is a capital crime of killing the head! Luo Zipao said sharply.

The others didn't have the heart to talk about it anymore, after all, they had also witnessed the last time the East Palace had an accident.

Although Luo Zipao said it ugly, the truth in his words was correct.

The forbidden army has returned to its previous solemnity and solemnity, and is dedicated to guarding the safety of the East Palace.

Inside the East Palace, Li Fengke was still thinking about how to tell the prince, and the distance of a few hundred steps was almost a stick of incense.

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

Jinxi, the eunuch who was in charge of grinding ink next to him, reminded him softly when he saw that the fifth prince had come in.

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

Only then did Li Yunxing raise his head and look at himself, and Li Fengke was ready to bow down and resign immediately.

"His Royal Highness the Prince, the younger brother will ...... if he has something"

Because his voice was so small as a mosquito and fly, Li Yunxing directly ignored what he said.

"Fifth Emperor Brother, come up and see how this picture of this palace is."

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

This painting ...... What is the drawing?

The lines are crooked, the ink is splashing, and it's hard to see what it is.

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

"What? Can't read it? ”

Li Fengke was already timid, and he thought that he was so stupid that he angered His Royal Highness the Prince, and he became stuttering again for a while.

"I, I ......"

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

He himself thinks that the painting is okay, maybe Li Fengke doesn't know much about these chariots.

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

Jinxi is the same as Li Fengke, in fact, he didn't understand what His Royal Highness the Crown Prince was painting at the beginning.

was asked by the prince, and he could only pay for a smile that was more ugly than crying, "His Royal Highness the prince, slave maid ......"

Li Yunxing felt that his head was full of black lines, and he couldn't understand such a simple and clear catapult draft!

Is your drawing skill so bad?

Suddenly thinking of painting potatoes to Zuliya, the princess of the Great Moon Clan in the Western Regions, the other party was also at a loss.

It's not that I haven't seen it, but my painting skills are too poor?

Li Yunxing sighed.

When I picked up the paper, I wanted to crumple it and throw it away.

At this time, Li Fengke suddenly stepped forward to stop him, "It's too ...... His Royal Highness the Prince. ”

"What's wrong?"

"Brother Huang painted it, but it's a catapult?" Li Fengke said hesitantly.

Li Yunxing nodded, Li Fengke saw it, and sure enough, he didn't see the wrong person!

"Exactly! This is a catapult that has been improved by the main shrine, which is more powerful and requires less manpower. ”

Li Fengke really didn't dare to compliment Li Yunxing's paintings, he just looked at the crooked side, which seemed to be the rocker arm of a catapult.

But in general, it was very different from the catapults he had seen before.

"His Royal Highness the Prince, it's better for the younger brother to write it, and you can dictate it, okay?"

Li Yunxing nodded, "Yes." ”

Immediately, Li Yunxing told Li Fengke of the modified version of the catapult.

In this dynasty, it is unlikely that Li Yunxing wants to build rocket cannons, after all, he is not a physical high-achieving student, but he still knows such a trivial thing as improving catapults.

In the Mengyuan period, the stone thrower reached its peak in development, and once erected 5,000 return cannons overnight, allowing the Jin people to break through the gate in one fell swoop.

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

Li Fengke listened to Li Yunxing's description while drawing the figure of the catapult.

"His Royal Highness the Crown Prince...... The younger brother thought that there was still room for improvement in this catapult. ”

"Oh?" Li Yunxing looked at Li Fengke in surprise, "But it's okay to say it." ”

"Add one more ...... here, and you can increase the power tenfold."
