The improvement of the carriage is not in a hurry.

What Liu Mingqi really did quietly was TNP explosives.

The picy acid was extracted and the successful production of the simple detonator was successful, so the picy acid explosive came to this world hundreds of years in advance.

During the experiment, Liu Mingqi was so afraid of death, so he asked Dazhu to wait outside, and ran into the bushes alone, detonating the picy acid explosive.

"Boom boom boom..."

When Liu Mingqi ran out in a panic, a deafening roar came from the woods, and the entire ground was shaking.

Even if it was raining lightly now, you could clearly see a huge stream of blue smoke and fire mixed together and rose to the sky.

Mushroom cloud...

There is naturally no mushroom cloud.

But this scene also scared Dazhu, who has always been very brave.

Except for subconsciously rushing towards Liu Mingqi at the first time, his mind was blank.

"Peng!"

The boy who had just escaped in a panic was thrown to the ground by Dazhu before he could even be glad, and almost fainted from pain.

He was so painful that he couldn't speak. Only Dazhu found that there was nothing strange around him, and the woods became quiet again, so he got up.

At this time, Liu Mingqi was almost dying.

He was helped up by Dazhu, and after a while, he could pass this breath.

He can't blame Dazhu for being reckless. He told Dazhu that when encountering such an explosion, the best way is to lie underground and not run around, otherwise the splashed fragments will easily kill people.

Dazhu remembered it firmly, so he threw Liu Mingqi to the ground and covered Liu Mingqi's body by himself. No matter how dangerous it was, he would be the one who was unlucky, not Liu Mingqi.

Sitting on the soil, Liu Mingqi looked at the woods where black smoke was still coming out, and then at the light rain falling in the sky, but she was not worried about the fire.

When he had the strength, the boy walked inside again.

Dazhu was so scared that he shouted: "Your Highness, it's dangerous inside!"

"Not dangerous. After the explosives explode, there is nothing left." Liu Mingqi smiled, "Come on, follow me, I'll let you see what the power of the explosion in the industrial age is."

Seeing the little master say this, Dazhu gritted his teeth and could only keep up, and followed closely.

He made up his mind that if there was any movement, he would run out with his little master on his back.

At that time, nothing the little master said was useless, but this was specially instructed by the princess.

The two walked into the woods, but in fact, Liu Mingqi didn't dare to go deeper into it, so she didn't have enough time to run out, so she only went in more than ten meters.

Dazhu was shocked to see that the three trees adjacent to the woods that were not close to each other, and fell down.

The two ends of a big tree are burnt black at both ends and smoke is still emitting.

The other two trees collapsed even more miserable, as if they were cut off from the middle by huge force.

However, their fractures are relatively clean.

But the open space among the three big trees was also blown up with a big hole.

The whole thing gave Dazhu the feeling that it was like a prehistoric beast raging here.

He also smelled a pungent smell.

Dazhu didn’t know that this was the smell of gunpowder.

As a PhD in Physics and Chemistry, Liu Mingqi missed the taste of this industry very much and took a deep breath.

Yes, it's very tasty!

The boy squatted down and began to investigate the deep pits and big holes on the ground and the damage to three trees.

He tied the picric bomb to a tree with ropes.

From the current level, although this equivalent of explosives is powerful, it will definitely not be enough to face the reef that is still strong by flowing water for thousands of years.

"Dazhu, let's go there."

Liu Mingqi greeted Dazhu and walked in another direction.

After a while, they arrived in a forest parallel to the place just now.

This place is different from what I just said. In the middle of several big trees, a large stone that is at least two meters high and has a diameter of two meters.

A small hole is faintly exposed under the big stone, which can be reached into one hand.

"Get things... take a big piece!"

Liu Mingqi ordered.

Dazhu hesitated for a moment and took out a picy bomb with about an adult fist from his backpack.

The outer skin of the bomb was wrapped in iron, and a copper tube was inserted into it, and the end of the copper tube was an opening.

Liu Mingqi first stuffed the picy acid bomb into the hole under the big stone, and then stuffed a fuse into the opening of the copper tube.

The fuse is five meters long, which shows how careful the young man is.

When Dazhu saw that Liu Mingqi started making fire again, he quickly said, "Your Highness, I'll light the fire this time! You go out first."

"I'll do it!"

Liu Mingqi thought for a while and said, "Don't worry, now I will teach you, see how I do it. When I reach the gates of hell, I can only rely on you. You must pay attention to safety."

"yes."

Seeing that Liu Mingqi was speaking solemnly, Dazhu nodded himself.

He could see clearly the power of the explosion just now, but in fact he felt a little more awe in his heart.

The deterrent power of this kind of explosion is much simpler and more practical than that of humans.

Liu Mingqi lit the fire note and said while approaching the lead, "You have also tried this lead at home. Remember to run immediately as soon as you see it, the farther you run, the better... I don't know what's going on in the environment of the Gate of Hell, but you have to think about it carefully and be sure to protect yourself."

"yes."

Dazhu said seriously.

Liu Mingqi can't swim by herself, but the original owner of this body is an expert in swimming, otherwise she wouldn't have dived in the river.

Just because such a big thing happened and after being rescued, Liu Mingqi said that she had a psychological shadow and could not swim anymore, and no one doubted it.

Besides, Princess Yu also made strict regulations, so Dazhu saw that Liu Mingqi wanted to get into the water, so he tied him up and went home.

Seeing the big pillar being solemnly opposed, Liu Mingqi pressed her heart and lit the lead with a fire fold.

"Sizi..."

Sparks splashed, and the leads burned forward rapidly.

Liu Mingqi just threw down the fire pie and wanted to turn around and run away. Suddenly, a huge force came. Dazhu suddenly carried Liu Mingqi on his shoulders and ran out of the woods like a flying.

Although Dazhu was carrying someone, his speed was much faster than Liu Mingqi just now, and he rushed left and right, just like a frightened rabbit.

Liu Mingqi wanted to shout, don’t expose me to the air. If the pieces fly over, wouldn’t I want to be in a state of rebirth?

But as soon as he opened his mouth, the cool breeze poured into his throat, choking him and coughing.

"Boom boom boom..."

"Bang bang bang..."

The pillar ran around for more than 30 meters, and then he heard a huge vibration behind him, accompanied by constant impact.

Because the distance was very close, the strong vibration on the ground was also felt by the pillars, and the vibration also spread to Liu Mingqi.

A wave of heat immediately gushed over. Seeing that the situation was not good, Dazhu fell to the ground cleanly again, and Liu Mingqi, a poor man, was naturally suppressed by him.

This time the explosion was obviously much more fierce than the last time.

In addition to the huge explosion, there are also knocking sounds and trees keep falling.

After a while, these complicated sounds slowly stopped.

Only then did Dazhu stand up with confidence.

When Liu Mingqi sat up, she coughed violently, but she smelled a very pungent smell again, and the cough became even worse.

He turned around and saw that Dazhu, who was looking at the source of the explosion, remained stunned.

When he stood up, he saw at least twenty or thirty big trees falling around him, messy, and bursts of thick smoke kept pouring out from the center.

Even if it rains lightly, it cannot block the mixed firelight.

It can also be seen that gravels of all sizes are embedded in big trees that have fallen or not.

Many are inlaid very deeply, and some even make a hole in the big tree.

Liu Mingqi raised her foot and wanted to walk inside, but Dazhu grabbed him: "Your Highness, you are dangerous, don't go!"

Dazhu is really a little scared.
