Datang: My private money was exposed by Li Shimin

Cheng Yaojin was just frightened just now, and he didn't react for a while.

Since that mysterious iron ball can cause such a big movement and almost cause him fatal damage, it can be completely applied to the battlefield.

Just imagine.

The densely packed enemy troops are rushing madly, and I have a certain number of iron balls. If I use them at the same time, how much damage will it have?

Li Shimin himself is a veteran in the battlefield, so naturally he immediately understood what Cheng Yaojin meant.

Yes!

Just one of those mysterious iron balls can make such a big hole in the ground, and almost seriously injured Cheng Yaojin. If it can be used on the battlefield, it will become a terrifying weapon that can control the situation.

"The kind of iron he mentioned just now...that kind of iron ball or iron ball, what exactly is it, do you know how much Jian'er has studied?" Li Shimin, who had reacted, immediately turned around and asked Wang Xuan.

Here, only he knows something about the mysterious laboratory. If there are really a lot of these things, or, like those glass products, can be mass-produced, then this time it will be a big profit!

however.

However, Wang Xuan smiled wryly and shook his head, "Your Majesty, I really don't know much about the things in this laboratory, even the mysterious iron ball that the general mentioned, I only just knew about it!"

Hearing his words, Cheng Yaojin and Li Shimin couldn't help showing disappointment on their faces.

but.

Since it is something Li Jian has researched, it must be in this mansion, and it may even be in the so-called laboratory, and maybe it will be harvested soon.

"Then... where is the laboratory you mentioned?" Li Shimin asked the most concerned question.

Without any hesitation, Wang Xuan turned around and led the two of them towards a room not far away. When Cheng Yaojin saw this place, the pain on his face also eased a bit.

Sure enough, it was the place where he found the mysterious iron ball. Maybe there are a lot of such explosive iron balls hidden in it.

If he can really discover something that can change the war today, then his credit will be great, and the injuries on his body will not be in vain.

soon.

Under Wang Xuan's personal leadership, Li Shimin followed him into the mysterious laboratory, and Cheng Yaojin, like a crab, tried hard to follow along sideways.

in fact.

According to the doctor's opinion, Cheng Yaojin shouldn't do too many movements now, it's better to be able to raise him with peace of mind, but how could he be able to stay at this moment?
Walking into the closed door, what was presented to everyone was a very messy room. There were many things in it, but they were not arranged in an orderly manner as they had discovered before.

Not only that.

There is also a special smell in the air, full of mystery.

Even Wang Xuan looked around curiously when he walked in, if the emperor hadn't come here in person today, even he wouldn't be able to come in and out at will.

Speaking of which, I still had their honor to get a glimpse of this mysterious laboratory!

Li Shimin walked in the front and saw the horseshoe on the table at a glance.

This is the only thing they can recognize!
The difference is that the horseshoes are placed on the table very casually, it seems to be the simplest thing invented by Li Jian, and he doesn't pay much attention to it.

"This is indeed the place where Jian'er studies things. We haven't seen it for a long time!" Li Shimin said with emotion while looking at the various things here curiously.

He originally thought that this time it would be the same as before, and he could discover something special, but he didn't expect that he came directly to the laboratory where Li Jian made the invention.

Any item here, I am afraid that it will have a shocking effect if taken out.

"Isn't this the glass developed by His Highness?" Cheng Yaojin accidentally saw a pile of round glass pieces piled up in the corner.

Judging from the size, it is completely different from what they have found before. If I remember correctly, the biggest use of glass is to install it on windows.

What special effect can this glass, which is the size of a shard, have?

Li Shimin and Fang Xuanling were immediately attracted, and hurried over to examine it carefully.

really.

There are piles of glass the size of shards here, and they have all been polished into a round shape, which seems to be a little uneven.

"It shouldn't be installed on the window, and it's not big enough!" Fang Xuanling casually picked up a piece, and looked at it in front of his eyes.

It was this random movement, Hao Xuan didn't let him sit on the ground.

Good guy.

Just now through this small piece of glass, for some reason, I saw those things on the table, which inexplicably became a lot bigger.

He rubbed his eyes vigorously, afraid that he might have made a mistake just now, so he deliberately looked through the glass again, and it was true.

Li Shimin noticed his abnormality instantly, frowned and asked, "What's wrong? What's wrong with this?"

Noticing that the two of them seemed to be abnormal, Cheng Yaojin quickly picked up a piece of glass and waved it in front of his eyes just like Fang Xuanling, but there seemed to be nothing abnormal.

"Your Majesty, take a good look, just put it at this distance!" Fang Xuanling personally signaled, and placed the piece of glass in front of Li Shimin's eyes.

really.

Those objects that were normal in front of him suddenly became several times larger through the round glass. If he hadn't seen it with his own eyes, he would never have believed such a weird thing would happen.

He also carefully studied the glass he discovered before, and through that glass, it was no different from what he usually saw.

How did this get so different?
Instinctively turned his head to look at Wang Xuan, and found that the other party also shook his head with a wry smile.

"This is really strange..." Li Shimin looked carefully at the round glass in his hand.

He had a feeling that Li Jian did not do it casually, and there must be some mystery hidden in it, but he hadn't discovered it yet.

Holding the piece of glass and trying it out, Li Shimin found something strange beside it.

This is a very long cylinder!

The size of the two sides is completely different, and as the length extends, the shape becomes larger and larger, and the round glass in the hand seems to be installed on both sides.

No wonder they just discovered that among the pile of glass, the sizes of the circles are different.

"This kind of glass should be used to install this kind of cylinder. The key is what is the use of it?" Li Shimin picked up the cylinder without hesitation, and played with it a few times in his hand.

"Your Majesty, would you like to take a look?" Fang Xuanling immediately reminded him with the experience just now.

Since the piece of glass just now can hold ordinary things several times, it must have a more wonderful effect when installed on this weird cylinder...
