"Wait, all the holes have been checked!"

"The depth is fine, and the holes are all wiped clean with thatch according to your request......

Pei Mi and the others reported one after another, and they all looked at Wei Ming with blank eyes, and their eyes were almost like beggars waiting for the immortals to turn stones into gold.

Not only Pei Mi and others, but also Li Jiao, Zeng Fanzhi, Wu Dong and even Chen Dong and other craftsmen, the people are also eager to wear it......

The slight difference is that Li Jiao, Zeng Fanzhi, Wu Dong and others have the same thoughts as Pei Mi and others, all hoping that Wei Ming can turn decay into magic, while Chen Dong and others all have strange expressions and let out bursts of strange laughter from time to time......

People who know the contradictions between a few people and Wei Ming, I am afraid that they can guess with their toes, and these guys are afraid that they are all cursing in circles in their hearts, and they wish that Wei Ming's method would not work.

Wei Ming naturally knew about these, but his appearance still seemed unhurried.

"You wait for the helpers, take these black powder, and wait for half of each hole!"

After handing over the black powder to Pei Mi, Hu Lijun, Wan'an and others, and explaining that they first filled half of the black powder in each cannon hole for later use, Wei Ming slowly began to move.

Half of the sulfur and half of the nitrate, grind into a fine powder, and then mix.

When mixing the fine powder of saltpeter sulfur, Wei Ming's expression finally became a little nervous.

Because when these two things exist separately, there is no danger at all except flammability, but once they are mixed together, they become extremely dangerous explosives, and their properties are extremely unstable......

If you're not careful, it's a boom!

After mixing, Wei Ming took a small portion of each of these fine powders and wrapped them in flexible mulberry paper and intercepted fire twists at one end to form a long garlic-like thing......

In this way, one of the most rudimentary explosive devices was formed.

At the same time, Pei Mi, Hu Lijun and others also came back to report, saying that the gunpowder had been loaded according to Wei Ming's instructions, and it was time to proceed to the next step!

"Grab these things and come with me!"

Wei Ming pointed to the explosive device that had just been made with a fire twist, and asked a few people to take him to the work surface.

"This is the key to breaking the mountain and breaking the rocks?"

Seeing these things, Li Jiao asked, and was quite curious and ready to pick it up and take a look......

"King Ping, be careful!"

Wei Ming hurriedly stopped it, after all, the amount of it could only cause a small explosion, but if it hurt Li Jiao......

Even if it's just a drop of hair, the consequences are unimaginable!

When he reloaded, Wei Ming was obviously careful, not only keeping irrelevant people away, but also doing everything himself.

The detonating device made of fire twist is filled into the hole filled with half of the black powder, and then half of the black powder is added, and then the top layer is filled with stone crushing powder, etc., and a blast hole is considered to be loaded.

Because it was the first experiment, the stonemasons only chiseled five holes, so in less than a moment, they were all loaded.

Wei Ming examined it and ordered Pei Mi and the others to cover the four of the already loaded cannon holes with stones, leaving only the cannon muzzle that was ignited first.

Such a purpose, of course, is because the fire twister is not a fuse or something else, and the explosion sequence can be controlled by using the length or even numerical control......

The gun emplacements were carefully selected, using the principles of mechanics to maximize the power of the explosion.

Once the order of the explosions is not right, the rocks will not be blown up at all.

Therefore, Wei Ming had to use the most primitive method, that is, after the first cannon was exploded, the second cannon was fired to detonate it.

The purpose of the cover-up is, of course, to prevent the impact of stones and other stones that have been blown up by previous detonation from affecting the muzzles of the guns that have not yet been ignited.

After everything was prepared, Wei Ming breathed a sigh of relief, and said to Li Jiao, Zeng Fanzhi, Wu Dong, and Xu Jin: "Why don't you want the king of Guangping or a few officials, or a few words?" ”

"It's just a mountain and a rock, what can you talk about?"

Several people glared at Wei Ming dissatisfiedly and said, "Hurry up, I can't wait to see the power of this explosive method waiting for you!" ”

"This is the first explosion in the world!"

Wei Ming said after a few words, such as the influence of using the original playful things in production and life: "The traditional method of opening mountains and chiseling stones will be replaced by the method of blasting from now on, and at this moment, maybe it will be left famous in history - King Ping and several Shangguan, don't you really plan to say a few words?" ”

Without waiting for Wei Ming to finish speaking, Zeng Fanzhi and the others looked solemn, and said to Li Jiao: "Such a meaningful moment, a certain person is not qualified for this, please King Ping!" ”

"It's a pity that the emperor and Aya are not there, so I can only be disrespectful!"

Li Jiao bowed his hand in the direction of Chang'an a few times, and then pulled Yao Shun and the like, and finally shouted at the top of his voice under Wei Ming's prompting: "Shoot the cannon ......"

"It's fired, everyone is hiding!"

After a burst of shouting one after another, Zhang Ziyu took a burning wooden stick and lit the fire twist, and at the moment when the fire twist emitted green smoke, he began to run wildly!

"Shinto!"

Seeing this scene, Chen Dong and the others were disdainful, and snorted and stared at Wei Ming, who was far away, and sneered: "Do these tricks, if you can't explode later, I want to see how his kid ends......"

Before the words fell, I heard a thunderbolt on a sunny day!

A large area of the ground suddenly arched like an earth dragon turning over, and then in the midst of the smoke and dust, a large amount of rubble roared up, smashing into all directions like a fire rain meteor!

That earth-shattering scene, I don't know how many people are crying wolves, damn it!

Even Zeng Fanzhi and the others, who were 100 meters away, trembled in fright and fell to the ground one after another!

Li Jiao also screamed as a ghost, and he was about to fall down.

Fortunately, Wei Ming was prepared, and he grabbed Li Lilian and said in a low voice: "King Ping, it's okay - image, pay attention to the image!" ”

"Oooh oh ......"

Li Jiao, who was shaking like chaff, made a sound for a long time, and noticed that the explosion had subsided, so he calmed down a little......

However, seeing most of the overturned rocks, Li Jiao still couldn't help but say with a pale face: "This kind of power is comparable to the power of heaven!" ”

Wei Ming was speechless, and he really wanted to remind Li Li not to be heavenly and mighty at every turn!

What he should pay more attention to is the increase in work efficiency brought by the use of explosives!

Just the mountain rocks that were blown up by this cannon were afraid that hundreds of people on the top would use hammers and hoes to smash the effect of a whole day!

In the same way, it would be much simpler to dig a hole in a dozen stonemasons every day, then blast the rocks with cannons, and the rest of the work, such as transferring the shattered rocks......

In comparison, the work efficiency has increased by more than 100 times!
