Letting Song Yingxing study explosives is really the right person, although this guy has not yet started compiling "Heavenly Creations", but professional people do professional things, this must be right.

"Boom"

With a loud bang, snow flew into the sky, and the snow on the trees near the explosion site was shaken off, revealing bare branches.

A large crater with a diameter of more than three zhang appeared on the white snowfield with black smoke.

"Squire, did we succeed?"

Song Yingxing stretched out his little finger and plucked his ears vigorously, and said to his subordinates:

"What are you talking about, I can't hear ......"

Everyone's brains were buzzing, Song Yingxing regretted a little, His Majesty said that when testing explosives, you must withdraw to a far place, and you must hide behind the bunker, and plug your ears with cork, if you are too close, you will either be easily injured or easily deaf.

Song Yingxing pinched his nose with his hand, closed his mouth and began to puff up, this is also what His Majesty taught him, if he is shocked and can't hear the sound clearly, use this trick, if this trick is not good, then ...... It must be hearing loss.

Fortunately, Song Yingxing felt a pop in his ears, as if a membrane was bulging outward.

Then the whole world sounded back to the same as before.

"Pinch your nose with your hands, shut up and puff out, watch my movements ......"

Song Yingxing gestured to the people around him, and everyone followed suit, and finally said that they could hear the voice.

"Let's go, let's see ......"

Song Yingxing led people to the side of the big pit, this is the explosives made with the ratio given by His Majesty, the fuse is made of an extended firecracker twist, in order to be safe, outside the explosives bag, Song Yingxing also ordered someone to wrap a thick layer of yellow mud.

"Lord Song, this kind of firecracker can blow up the mountain, and in the future, mining will not need to spend a lot of manpower to excavate."

"Lord Song, if the outside of this black powder is not wrapped in yellow mud but gravel, it will definitely be more powerful and lethal if it explodes."

Everyone began to gossip, Song Yingxing nodded slightly, this is also what His Majesty said, don't underestimate these craftsmen, their ingenuity is not only not lost to those literati who have read poetry and books, but also better.

The ratio of explosives is strictly confidential, so the process of making explosives bags was completed by Song Yingxing independently.

"Lord Song, what kind of formula are you using, and how can it be so powerful?"

Song Yingxing said with a smile:

"This recipe was told to me by His Majesty, it is top secret, you better not inquire, now, let's study what kind of container should be used to hold and preserve these explosives."

Song Yingxing led people to find the place where the coal mine was found, and made ten explosives bags.

"Clear the snow from the mountain, let the Khitan slaves dig holes along the mountain, and let's test if we can blow up this mountain directly."

After several days of preparation, hundreds of Khitan slaves dug several holes in this mountain that could barely be drilled into people, ranging from a few meters to a dozen meters deep.

This time, Song Yingxing did not wrap the yellow mud on the outside of the explosive bag, but personally stuffed the explosive bag into the hole one by one and connected the fuse.

To be on the safe side, three fuses were connected to each explosive package, and after Song Yingxing carefully checked it, he ordered everyone to withdraw to a far away.

The people responsible for lighting the fuse are all soldiers of the Great Zhou Guards, and they are all young and strong and fast.

"You guys, after lighting the fuse, you must run to us quickly, and you can't delay a minute......

"Everyone, plugging their ears with cork, hid behind cover, and counted the explosions carefully."

"Subordinates obey Lord Song's orders."

All the work was ready, and Song Yingxing gave the order to light the fuse.

The fuse was lit, and several young soldiers began to run wildly to the perimeter, quickly running behind cover and hiding.

"Boom"

"Boom"

There were several loud explosions in succession, and everyone who was hiding behind the cover clearly felt that the ground beneath their feet began to tremble.

"Boom"

……

Song Yingxing counted them one by one, and sometimes, there were two explosions in succession.

Finally, the earth stopped trembling and the explosions stopped.

"Lord Song, the number of lowly posts is nine."

"Lord Song, the number of lowly positions is also nine sounds."

Song Yingxing's brows furrowed, he made ten explosive packets, and he counted nine explosions just now.

"Wait, don't go ......"

As everyone continued to hide behind the bunker, they could faintly hear the rumbling sound of large rocks rolling down and the clatter of sliding stones from the direction of the test explosion mountain.

"Boom"

The tenth explosion finally sounded, and he stayed for a while, and when all the sounds stopped, Song Yingxing arranged again:

"You, in groups of three, go over to investigate in turn, and after finding a safe route, plant a red flag as a mark, we don't know what the mountain will be blown up into, and whether there will be a secondary landslide, these are all things that must be paid attention to."

"Inferior obedience."

The fifteen people of the first echelon were divided into five groups to investigate the situation of the bombing of the mountain.

Soon, the news came back, only part of the mountain had collapsed, and part of it had been blown loose, and part of the larger area had not moved.

Song Yingxing led the people along the safe route into the area of the bombing mine and carefully investigated.

Overall, the explosion was a success, and a large amount of black coal was blown open and scattered within a radius of the explosion area.

But Song Yingxing still sighed in his heart.

His Majesty also said that explosives can only be used in the early stage of mining, and once the design is not thorough, the amount of explosives required for the explosion cannot be accurately measured, and the unreasonable design of the depth of the hole will affect the effect of the explosion.

"Send someone to inform the Ministry of Industry and ask them to organize people to start mining, here, leave 500 soldiers to garrison, need to be warmed, you can burn coal, but you must pay attention to ventilation."

All of these were told to Song Yingxing by the little emperor, what carbon monoxide poisoning, Song Yingxing didn't understand, and later the little emperor told him that he must pay attention to ventilation when burning coal, and it is enough to remember this.

Guo Zongxun was very happy to learn that Song Yingxing had successfully tested explosives in Huaizhou, and that he had successfully blown up a mountain, and that the coal that had been blown up and scattered on the spot was enough to be mined for a while.

"Spread my will, let Song Yingxing take people to Taiyuan City with supplies, and hit him a few times with explosives, I won't believe it, and Liu Jun will not surrender."

Before all the tests were completely completed, Guo Zongxun asked Song Yingxing that the ratio of explosives could only be known by himself, and all the explosives packages could only be made by him alone.

"Liu Aiqing, I have taken care of the literati who have sold books and betrayed the country, and now, the problem is again, the preparation of explosives, the production of grenades and explosives bags, the manufacture of ballista carts and catapults...... How do you keep it a secret? ”
