Most of the miscellaneous research in Li Shen's research institute was put forward by Li Shen and then let these people ponder it slowly.

It's also about accumulating some basic data.

The three-bow bed crossbow is one of them, which was also proposed by Li Shen himself, this kind of crossbow is based on the strong crossbow with two strong bows to achieve two positive and one negative.

The winch is used to draw the line, and the arrows used are similar to the spears used by soldiers, except that the front end is a Mitsubishi arrowhead.

It takes about twenty people to pull.

Later, Li Shen installed a few pulley sets, and increased the hardness and tension of the strong bow, although it still takes about 20 people to operate, but the range can indeed reach 1,000 steps.

It played a great role on the battlefield of Goguryeo, and with such a large projectile power, it was not at all difficult to bring the fire oil catapult to the city wall at a distance of three or four hundred steps.

Li Shen actually didn't report it, but forgot to report it, and Wang Xuance, the chief historian of his house, saw Li Shen so calm and relaxed.

I thought that my son had said hello to my father, so I didn't meddle with anything.

That's why there was such a big misunderstanding.

In fact, not only these, Li Shen's guard battalion is also equipped with a lot of things, equipped with different weapons and equipment according to the battlefield,

For example, in Chang'an City, the guards are equipped with small hand crossbows, although the range is short, but the winding is fast, small and lightweight.

Like going to Goguryeo, Li Shen's 2,000 men were equipped with long-range compound crossbows and compound bows.

Li Shen is very persistent in long-range strikes, and the compound crossbow goes down in waves, and then he can ride a horse and fly a kite with a compound bow.

There are also various types of swords, shields, armor, and much more.

"Lord Wang, since there is nothing to do, the old slave will be taken away." Wang De saw Li Shen falling into thought and said softly,

Then he waved his hand at Li Zhiming next to him, meaning to hurry up, while King Ji had not repented.

Li Zhiming understood and quickly ordered his subordinates to load the cart quickly, and soon Li Zhiming took people to drive the carriage away.

Wang De saw the carriage going away, and also said to Li Shen:

"Lord Wang, the old slave has also retired."

"Wait." Li Shen came back to his senses and said.

"Lao Wang, you go back and tell Aye, I will immediately personally copy all the drawings of the research institute and send them to the palace."

This matter is indeed Li Shen's negligence, but there is still a chance to make amends.

In fact, ordinary swords, as a prince, it doesn't matter if you want to play, you want to study how you want.

But a strong crossbow is not good, especially a three-bow strong crossbow like Li Shen, or a composite three-bow strong crossbow, which is extremely powerful.

Even if his father trusts him, there are still rules.

Wang De nodded with a smile, and then looked left and right.

Li Shen comprehended and waved his hand, and the guards around him walked out ten steps, and Wang Decai approached Li Shen and said in a low voice:

"Lord Wang, be careful, someone is staring at you, Your Majesty received a secret fold, but it was not signed, and I don't know who put it in Zhongshu Province.

It impeached you for secretly manufacturing large weapons and equipping private armies, and said that you had great intentions and intended to rebel, and found an opportunity to prepare for a mutiny and assassinate Your Majesty and the Crown Prince.

Your Majesty is using this method to remind you not to be too frizzy, to be cautious, and this time it is just to teach you a lesson.

Because the secret fold compares you to Sima Yi. ”

After Wang De finished speaking, he turned around and got on his horse and walked away.

"I'm grass," Li Shen roared.

"Which bastard wants Lao Tzu to die?"

Although Li Shen is not a historian, he has not read much TV dramas and novels, and in history, none of the defendants who are said to be Sima Yi have a good end.

This is all caught up with Sima Yi's curse technique.

Li Shen scolded all kinds of modern words in his heart for a quarter of an hour before he finally calmed down, this matter must have been done by someone who had an enmity with him,

Then who has an enmity with himself, the family of scholars.

There were many generals of the Eastern Expeditionary Army who went to Goguryeo, and in Chang'an, there were countless pairs of eyes staring at him.

Including all his estates.

"Rengui, the research institute has sent more manpower, and all craftsmen must be equipped with special cars and special personnel to protect them when they go out. No one is allowed to approach within three miles of the Institute. ”

Li Shen ordered to Xue Rengui next to him,

Xue Rengui understands in seconds, obviously for protection, but in fact for surveillance.

Li Shen didn't have the heart to go to the barracks to inspect anymore, so he chatted with Xue Rengui roughly, and said that Yuanzheng's reward would come soon.

Li Shen got into the carriage and rushed to the palace.

He went back to get the drawings and sent them to the palace to Li Shimin today.

And we also have to test Li Shimin's attitude, this matter can be big or small, if you believe it, you will have it, and if you don't believe it, you will not have it.

In history, high-ranking officials and ministers who were unjustly killed, the prince and the prince will have it, and he doesn't want to be a part of it.

It's really not good, he would rather give up some benefits, it doesn't matter, money is something that can be made when it is gone.

He knows very well that the royal family has any family affection, and Li Shimin's family relationship with him is based on his ability.

Li Shimin has fourteen sons, why should he kiss you.

Because you are useful.

Li Shen is actually an upstart, and in his previous life, he was just a crowd of sapient beings.

Therefore, it caused Li Shen's attachment to money after his reincarnation and the pleasure of enjoying squandering.

Li Shen returned to the palace and went directly to the study, and took out a box from the dark compartment of the bookshelf.

This box has been with him for more than ten years, and it is full of useful drawings and information.

Li Shen found out the design of the three-bow crossbow, and walked out of the palace again and went straight to the palace.

In the Liangyi Palace, Wang De came back to restore his life.

"What is the attitude of the old ten?" Li Shimin asked.

"Back to Your Majesty, as Your Majesty expected, His Royal Highness King Ji is still the same as usual, there has been no change at all, and he is still so arrogant and domineering,

If it weren't for the timely departure of the old slave, Li Zhiming would not have been able to deal with it.

And King Ji also said that His Majesty would pay 200,000 yuan to buy it. Wang De replied with a smile as always.

Li Shimin nodded, he asked Wang De to go to test Li Shen's reaction,

"You said someone accused him of rebellion, how did he react?"

"Back to Your Majesty, King Ji didn't react at all, but when the old slave left, he vaguely heard the scolding of His Royal Highness King Ji." Wang De answered truthfully.

Li Shimin nodded again, Li Shen's reaction was relatively normal, and when a normal person heard such a big thing, his first reaction was to be confused.

Then there is anger, if Li Shen really has a problem, he will also show panic as soon as possible.

Li Shen is only sixteen years old, Li Shimin doesn't believe that his son will have such a city, in the past ten years, Li Shen has always been a person who is moody.

His son was just smart, but not shrewd. Unlike those officials in the court, they are all human spirits.

"Did you do what I asked you to do?" Li Shimin asked again.

"Back to Your Majesty, the old slaves have all been done, dozens of carriages entered from the east gate, and after half a circle, they returned to the Beiya military camp.

The car didn't cover anything, and it didn't drive the people away. Everyone could see that the car was loaded with weapons and armor. Wang De continued.

"Well, that's good."
