Datang: My private money was exposed by Li Shimin

"Whoosh..."

Accompanied by the crisp sound of piercing through the air, the crossbow arrow flew across quickly and hit the trunk of the small tree accurately.

With Li Shimin's ability, it's nothing to do this. The key is that he was very relaxed during the process and didn't spend too much time aiming.

Just like what Wang Xuan said just now, with the scope on it, it is easier to hit the target.

and.

He now suspects that the crossbow in his hand has been modified, because it does not have the strange feeling of holding an ordinary crossbow in his hand at all.

To know.

Regardless of any weapon, it takes a long time for people to get used to holding it in their hands. Only when all conditions are right can they exert their greatest power.

But from the moment I held the crossbow, I didn't feel that jerky.

"Zhijie, try it!" In order to confirm his feelings, Li Shimin personally handed over the crossbow to Cheng Yaojin. He is an expert in this field and should be able to experience different feelings.

really.

After Cheng Yaojin took over the bow and crossbow, he also targeted the small tree. After some operations, the crossbow arrow still hit the trunk of the small tree accurately.

When Cheng Yaojin put down his bow and crossbow, he couldn't help frowning slightly.

Sure enough, he also felt that unusual feeling!

"Your Majesty, this crossbow is extraordinary. Your Highness must have made some changes. When I used it, I didn't have that jerky feeling at all. It's so smooth!" Cheng Yaojin seemed to have sensed Li Shimin's thoughts, and said after a little hesitation .

"It looks like...we have found something good to strengthen the army again!" Li Shimin laughed very proudly.

Now he can almost be sure that his son is Datang's future hope.

The situation is developing in the direction I imagined, and it will not be long before Datang will become the real overlord of the world.

And I... will become an emperor through the ages!
Thinking of that situation, even Li Shimin couldn't help getting excited.

Isn't it just for this goal that he has done so much back and forth?
After discovering so many good things, their actions certainly did not stop. In the following time, a mirror that was clearer than the bronze mirror was found here.

This seems to be very similar to the glass I saw at the beginning, but the difference is that in this kind of mirror, you can see your own face clearly without any other hues.

Replicated everything exactly and looks pretty amazing!

only.

Compared with the things they discovered just now, this mirror looks a bit ordinary.

of course.

After discovering so many good things in the laboratory, what Li Shimin was most concerned about was the explosive iron ball.

This not only has an extremely powerful impact on vision and hearing, but also has an unimaginable influence.

If that thing can be discovered and mass-produced, it will completely change the situation, even the mere Turks.

At this time, the one who understands Li Shimin's thoughts best is Cheng Yaojin.

In the process of searching for the good treasure, he has been paying attention to the clues about the mysterious iron ball. Unfortunately, he searched the entire laboratory, but found nothing related.

Just when he was about to give up, suddenly, next to a certain box, he found something like a lead wire, which was very similar to the burning thing on the mysterious iron ball.

Cheng Yaojin was excited and quickly picked it up, but soon he was disappointed.

This is not the mysterious iron ball, but a much smaller elongated object. The whole body is wrapped with paper, but a lead wire is left on the head.

"Did you find something?" Li Shimin has been paying attention to Cheng Yaojin's actions all the time, of course he discovered his abnormality immediately.

I thought he really found a clue related to the iron ball!
"It's not that thing, it's just a resemblance!" Cheng Yaojin pointed at the wire and shook his head slowly.

"Your Majesty, this thing is called a firecracker. If I remember correctly, His Highness failed many times to make this thing!" Wang Xuan also walked over, looking at the thing in Cheng Yaojin's hand and explained.

Regarding these little things, he used to hear Li Jian mention them often, and he knew them relatively well.

"Firecrackers?" Li Shimin raised his eyebrows.

"It's just that when this fuse is ignited, there will be a relatively violent sound, and even bursts of sparks will appear. Your Highness said that this kind of thing is usually used during festive occasions!" Wang Xuan continued to explain.

In fact.

He was also quite excited when he saw the firecrackers. He just wanted Li Shimin to test it on the spot, so that he could learn a lot from it.

really.

Hearing that this thing would make a noise, and it might even be the explosion of the mysterious iron ball, Li Shimin immediately became excited.

He immediately asked Emperor Xuan to bring a torch, ready to test it himself.

But before he could make a real move, Cheng Yaojin hastily held the firecracker in his hand.

"Your Majesty, you can't try it casually. This thing is quite dangerous. If you are not careful, you may threaten yourself. Your Majesty can see the state of the subject..." Cheng Yaojin said nothing to let Li Shimin try it himself.

Now no one knows how much noise this firecracker can make. If it is more powerful than the mysterious iron ball, wouldn't it put Li Shimin in danger?
Hearing the argument between the two, Fang Xuanling involuntarily took two steps back. He is not willing to try such a dangerous thing. If he is like Cheng Yaojin, whose buttocks are constantly bleeding, it will be a big mess joke!
In the end, Cheng Yaojin volunteered and decided to test the power of the firecrackers.

Anyway, I've already been injured, so I'll do it again!
then.

Cheng Yaojin held all the firecrackers he found in his hands, took out one first, went outside the laboratory, and lit the fuse on the torch.

Seeing that the fuse was burning, he threw the firecracker out without hesitation.

With the experience of that mysterious iron ball, he used his full strength this time.

The firecrackers were thrown far away, and the smoke drew an arc in the air, but after falling on the ground, there was no response for a long time, but the smoke continued to rise.

Nearly a quarter of an hour passed, and everyone still didn't wait for any reaction. Li Shimin's original anticipation dissipated a lot at once.

The firecrackers didn't seem to be as powerful as expected, but it was just a burst of smoke.

Cheng Yaojin was a little unconvinced, so he took out another ignited fuse, and threw it out with a little force.

This time, it was the same as before, a lot of thick smoke started to come out, and then there was a soft noise, and a small light flashed, and then there was no movement...
