On the eighth floor of the base, a spacious, fully enclosed hall with dim lights inside. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The hall was empty, with little equipment inside, except for the scattered metal brackets and bunkers of various shapes. These bunkers are non-stationary, can be moved to any position, and are very sturdy, with a metal internal structure and a soft, thick material wrapped on the outside.

The walls and floors are covered with a 30 cm thick and elastic protective compartment, which, according to the Manual, is not only sound and shockproof, but also fireproof and heat-absorbing.

Sang Nan, Gong Yehan, and a few craftsmen wore helmets and goggles, hiding behind a thick bunker, silently watching Runye in the center of the hall.

At this time, Runye, wearing a protective suit that looked extremely bulky, stood in front of a pit in the center of the hall, and several shiny metal brackets were placed around the pit.

In his right hand, he also held a short black rod, thick at the front, thin at the back, and a huge pull tab at the end.

This is a place to test the effect of the explosion, and the object of the test is the black short stick in Junno's hand. This object is called a grenade, and it is the same weapon as the previous mines and mines, but the structure is much more complicated.

"Everyone, hide, I'm going to start!"

Runye looked a little nervous, shouted to the people behind the cover, and after hearing everyone's drink, he used the middle finger of his left hand to put the pull ring at the end of the grenade, and pulled it off violently, and then saw a faint light smoke suddenly coming out of the place where the pull ring fell off.

Runye shook his hand, threw the grenade into the pit in front of him, and quickly hid behind a bunker beside him, silently counting in his heart:

One, two, three, four, five......

Rumble!!!

The pit burst into flames, and the grenade was blown apart at once, and the fragments flew out fifteen or sixteen meters, hitting the surrounding bunkers with a thumping sound, and several metal supports were also blown to pieces and scattered on the ground.

A wisp of smoke rose and the surroundings were calm. Everyone was speechless with the sheer power of the grenade.

It's a success! It's a success! Runye was the first to wave his hands and shouted excitedly. Sang Nan and the others were also so surprised that their eyes lit up, and they rushed to the crater to check the traces of the explosion.

I saw that the open space around the pit was littered with pieces of broken iron, and some were deeply embedded in the surface of the bunker. Most of the metal frames were toppled by the concussion of the explosion, and only two were bent and deformed by the explosion.

Powerful!

Seeing the mess in front of him, Sang Nan smiled from ear to ear, and the word instantly came to mind in his mind.

Moreover, this is only the power of a grenade, if 10, 20, 100 explode at the same time, what will be the effect?

He finally let go of a boulder in his heart.

It turned out that Sang Nan agreed to Emperor Xingchen's request, and at the same time raised a lot of problems to face. Among them, the one he feared the most was the penance of the metal skeleton of the temple. If it was just a gap in the realm, he might be able to find a way to make up for it, but the other party's metal skeleton was simply the nemesis of a ninth-level martial artist, if it weren't for Sang Nan's star qi that destroyed his metal structure, he was afraid that Ji Tieyi and Ji Poyu would die in his hands. If this problem is not solved, the entire Northern Demon Plain will not be the opponent of the Temple.

For this reason, Sang Nan bargained with Xingchen Tysenon for a long time before grinding a design drawing of a grenade, Sennon confessed that the design on this drawing is just a technology eliminated by the Blue Sea Starmen in the future, but it is very powerful and has once equipped the whole army. It should be more than enough to deal with the kind of modified person who has a metal skeleton.

And Sennon also told him that although this kind of transformation is strong, the number is not very large, first, this transformation process is very painful, not everyone can bear it, and second, the probability of success of transformation is not very high, and it is rarely used now.

When Gongye Han and Runye came to the base, Sang Nan confessed to the two of them, putting the production of this grenade in the first place, and it must be completed as soon as possible, for this reason, Gongye Han and his subordinates studied the drawings and related processing equipment day and night, and finally with the help of Yu, they successfully made three samples.

The production process of the grenade is not complicated, otherwise it is impossible to equip the whole army on a large scale, but it has a lot of parts, including the bullet body, the pull ring, the steel pipe, the copper sleeve, the friction coil, the brushed copper wire chassis, the extension pipe, the brass sleeve and the threaded bottom cover of more than a dozen parts, the shape is like a short rod, the projectile body is cast of pig iron, which is filled with explosive materials based on yellow clay, and a large number of steel balls.

According to the drawings, this kind of grenade uses a pull delay trigger fuse, which greatly improves stability and safety compared with the direct triggering of mines and falling mines in the past, and is also convenient to carry.

The point is that this grenade is simple to use and can be used with a little training. Moreover, it has a handle, which makes it easier to control the landing point, and the throwing distance is relatively far, and it is not easy to slide after landing.

"Childe, I was able to successfully make a grenade this time, thanks to Yu's help, otherwise those machines and equipment would be enough for the two of us to be busy, you have to thank people!" Gongye said to Sang Nan with a smile.

"Thank you, you must thank you!" Sang Nan also said with a smile. He's in a good mood right now and he's happy with the results against Lei.

"How long does it take to make a grenade like this, and is there enough material?"

"If you take the assembly line operation, 300 craftsmen can produce about 300 pieces per day!" Gong Yehan calculated carefully and said to Sang Nan:

"The shell materials are very ordinary, except that the main ammunition is made of five-colored soil! But we still have a lot of five-color soil! ”

"That's good!" Sang Nan said calmly: "Immediately implement manpower, and rush to produce a large number of such grenades, the more the better." Be careful with confidentiality and security, though! ”

"Okay! I'll arrange it! Gong Yehan led the people away with an excited face.

At this time, Runye, who had just taken off his protective clothing, came to Sang Nan and said in a deep voice: "Childe, I still have an idea!" ”

"What thoughts?" Sang Nan asked with interest.

"This grenade shell is all standard modeling, there is no difference. So I thought, can you properly swap the explosive components inside, such as adding some flammable ingredients, ingredients with blinding substances and irritants, or adding an appropriate amount of hot melt, so that it can be used on the battlefield, isn't it more flexible? Runye said a lot of thoughts at once, which was obviously related to his continuous research over the years.

"Oh? What is a hot melt? ”

"When a hot melt and a kind of iron powder are ignited, they can continuously release high temperatures and turn into molten iron, which can ignite or melt anything they touch!"

"Runye, you're a killer!" (To be continued.) )
