Datang: My private money was exposed by Li Shimin

Li Shimin stared fixedly at the blueprint...

Think back then.

After he found the blueprint in that small temple, he successfully made the drum car, which provided great help to the people's production.

nowadays.

In this specialized research laboratory, the same blueprint appeared again, and one didn't need to think about it to know that there were definitely good things recorded on it.

Therefore, without any hesitation, Li Shimin immediately picked up the blueprint, put it on the table beside him and slowly spread it out.

now.

Cheng Yaojin, Fang Xuanling and Wang Xuan also walked over, and everyone's eyes were focused on this blueprint.

I see.

On this blueprint, there are two wheels and a huge long tube. Next to it is the mysterious iron ball they were looking for just now, as well as related production methods.

It turns out that the mysterious iron ball is called a cannonball, and the mysterious object drawn on the blueprint is called the Cannon of General Shenwei.

Although the above is only a detailed drawing of the production process, it does not describe the function and power.

but.

After witnessing the power of the mysterious iron ball, everyone knew in their hearts that this thing called General Shenwei's cannon must have extraordinary power.

No need to think about it, this is also one of the weapons made by Li Jian.

"Your Majesty, according to the statement above, the iron ball I discovered before is just a part of this weapon. Even a part of it is so powerful. If it cooperates with each other, what kind of scene will it be? ?" Cheng Yaojin looked at the blueprint in front of him and said excitedly.

He is a person who has experienced the whole thing, and he can best understand the true feelings!

the most important is.

According to this blueprint, the mysterious iron ball can indeed be produced in batches, and the method is right in front of them.

"Great..." Li Shimin suppressed the excitement in his heart, carefully put away the drawing, and put it in his arms.

He hasn't fully figured out the above things, but he can be sure that this thing called General Shenwei's cannon absolutely has shocking power.

Such things must be kept by himself. After Li Jian returns, he will immediately start large-scale production, and he will accept everything that can improve the combat capabilities of the army.

There is silence in the laboratory...

at this time.

The faces of people like Empress Changsun and Cheng Yaojin were filled with endless shock.

Li Jian refreshed their cognition again and again, which is simply too scary!

It seems that there is nothing he can't do, from the simple gold and silver treasures at the beginning, to the current Shenwei General's cannon, each of these piles is full of mystery and horror.

Cheng Yaojin's respect for Li Jian reached its peak.

"With the help of His Royal Highness Sheng Wang, the power of the Tang Dynasty is just around the corner. Sooner or later we will wipe out the mere Turkic border troubles!" Cheng Yaojin was full of pride, and it was even more difficult to restrain his expectations for the future.

As soon as these words came out, perhaps to express his emotions, or perhaps instinctively, he punched the wall next to him.

"boom……"

Accompanied by a slight noise, a dark space suddenly popped up under the wall.

This sudden change shocked everyone present.

Cheng Yaojin thought it was some kind of hidden weapon, and instinctively used his body to block Li Shimin and Empress Changsun, because his buttock was injured and it was very inconvenient to move.

Coupled with the fact that the accident happened too suddenly, his appearance was quite funny.

Seeing his current state, everyone couldn't help but smile.

But soon their attention was focused on the hidden box that popped up, and their mood became tense.

obviously.

What good things are hidden in this secret compartment!

Just imagine.

They discovered these things just now, each of them is enough to shock the world, and these are all items on the surface.

It's hard to imagine how good something like this is carefully hidden in the secret compartment!
Li Shimin swallowed hard, stepped forward very cautiously, came to the side of the dark pavilion, took a deep breath and opened the lid on it himself.

He was already mentally prepared, and the things inside could definitely refresh their cognition again.

however.

When the secret compartment was opened, the contents inside looked ordinary, but they were just square jade-carved boards, all of the same size.

the difference is.

There are different patterns carved on it, which looks a bit mysterious, but Li Shimin can be sure that this thing should not be of much use.

Maybe it's some kind of ornamental item!
Li Shimin was a little disappointed. Cheng Yaojin and others stepped forward to see the same thing. Their hopes were too high. Seeing the things inside now, there would naturally be a gap.

"This is a toy invented by His Highness. It's called Mahjong. According to His Highness, it is for four people to play together, and the mystery is endless!" Wang Xuan finally walked over. smiled.

At the beginning, he also thought that there was something huge and good hidden in it.

But I didn't expect that it was just something made by Li Jian to pass the time.

He was lucky enough to experience it back then, and this thing is indeed quite mysterious. There are very few things that can be entertained in this era, and things like mahjong can perfectly fill this gap.

He was very sure that when people like Li Shimin discovered the mystery, they would never be able to escape the magic power.

"Toys?" Li Shimin frowned.

For so long, everything they have discovered can bring great benefits to the court or the world, and nothing has been produced purely for individuals.

Moreover.

Doesn't this thing look like a toy?

"You said just now that you want four of us together, we have enough here, why don't you just come and experience it?" Empress Changsun seemed to be in high spirits, she looked at Wang Xuan with a smile and said.

Hearing what Empress Changsun said, Wang Xuan immediately became interested. He hadn't played mahjong for a long time, and today he just took advantage of this opportunity to have a good time.

then.

He immediately had the table moved, and benches were placed in all four directions.

Seeing this scene, Cheng Yaojin immediately felt numb...

He knew that no matter what happened next, it had nothing to do with him, because it was impossible to sit down because of the injury on his buttocks.

soon.

Wang Xuan then took out the mahjong from the secret compartment and placed them all on the table.

While operating, he explained the mystery of mahjong to everyone.

At the beginning, Wang Xuan didn't have a good way to deal with the confusion of these rule-type people, so he could only let them pass on their experience while fighting...
