Qin Zheng took the musket given by the old craftsman, looked at it carefully, and could see that this was a model from the early Ming Dynasty, but it was actually a musket, not a world-famous arquebus.

This is made according to the materials of the early Ming Dynasty, and there is also the participation of Huibu craftsmen, but the quality is really average.

Problems such as exploding, overheating, etc., can't be solved by looking at the map, but fortunately, Qin Zheng didn't plan to equip the troops now, so he just showed them to everyone.

At this time, all the ministers also gathered around, and they all looked at this black iron "burning stick" with curious eyes.

Qin Zheng was not ambiguous, and directly threw the fire gun to them to play with, and then turned his head and motioned to the old craftsman to prepare for a test launch.

Everyone present didn't have much research on machinery except Zilian, and they couldn't see any doorways after taking turns to touch it for a while, but Zhao Gao, who was careful, heard the name Huoji, and vaguely felt that it had something to do with Tianlei.

Zhao Gao's idea was soon verified, and the old craftsman first took away the firecracker, filled it with lead wrapped in black powder and silk, compacted it, and tied it to a crossed wooden shelf.

Then he asked everyone to step back, and he took the lit incense to touch the fire door medicine room, and then heard only "Bang! With a bang, the gunpowder exploded violently, and the lead bullet was sprayed out of the barrel of the gun, and it went straight ahead, and at once it was on the thin wooden target used for the bow and arrow.

Yingyi and his party didn't even have time to cover their ears, they were so frightened that their faces turned white and their hearts were desolate, and they couldn't speak for a long time, just staring at the fire gun.

Presumably, the "embarrassed" old craftsmen of Yingyi and others are not much better, after all, this fire gun is a handmade product, and the materials used are also old craftsmanship, and they have not caught up with the good materials of the blast furnace.

The only one who was more calm was Qin Zheng, who not only stayed away from the explosion range in advance, but also blocked his ears, and checked the target not far away as soon as possible after launching.

The result is that Qin Zheng's mentality is very complicated now, although this test launch was successful, Daqin finally solved the problem of firearms from scratch (not counting those monkeys).

However, this shot was only more than 20 meters away from the target and did not hit the bull's-eye, and the preparation time was also long, and the whole field was in a mess after the shot, and it was impossible to estimate every few minutes if you wanted to fire it again.

This level is suicide when used on the battlefield, so don't look at the fact that this gun is quite decent, but the level is not as good as the three-eyed gun of the Ming Dynasty, and the gap with the Japanese Tanegashima iron cannon is even greater.

Yingyi, who finally came back to his senses, hurriedly flattered: "Your Majesty, my Great Qin army is really empowered by such a divine object!" ”

Immediately, everyone also opened their mouths to congratulate, even if Qin Zheng was not satisfied, it was not good to hit everyone, so he nodded in cooperation and asked the old craftsman to clean up the venue. Then he was fetched another invention on which he had high hopes.

It was a black iron ball, and there was a small hole in it, and a lead wire was deep in the hole, which looked like a black melon from a distance.

However, this melon is only a little bigger than a fist, and it is actually a Song Dynasty grenade "thunder" made by Qin Zheng according to the "General Essentials of the Martial Arts".

Compared with the fire door gun, Qin Zheng is more optimistic about this "thunder thunder", this thing has been used since the Northern Song Dynasty, and it is much less limited than the fire door gun.

This time, Qin Zheng didn't need the old craftsman, he directly let everyone disperse, took the incense to light it himself, quickly put it in place after ordering, turned around and ran.

With the experience just now, everyone hid far away this time, and their ears were blocked very tightly, just waiting for Qin Zheng's "big guy" to roar.

As a result, Qin Zhengdu has been retreating for a long time, and the big guy is in the same place, just smoking and not exploding. Qin Zheng immediately understood that this was a dud, either the gunpowder was damp or there was a problem with the lead.

He couldn't help but think: this garden is clean enough and hidden, but the humidity is too much to be a long-term place, and it seems that future development will have to find a new place.

When Qin Zheng was thinking, the old craftsman was already sweating profusely, Qin Zheng finally inspected it once, and brought almost all the important ministers, but the experiment of a weapon failed, where to put the face when it was passed out?

Thinking of this, the old man fell to his knees with a thud, and said while trembling in fright: "Your Majesty, the little people are guilty!" Please be gracious, Your Majesty! ”

Qin Zheng also knew that Qin Guo attached great importance to factory production before, and craftsmen who made too many defective products were not punished lightly, so they could achieve assembly line production and interchange of parts.

Qin Zheng will definitely continue to focus on quality in the future, but he also knows that there is no failure in the development of new technologies, if he fails once and cuts a worker, then Daqin will have no one available in a few years, right?

So Qin Zheng hurriedly put on a kind smile, stretched out his hand to pick up the old craftsman, and said with relief: "It's okay, it's okay, it's new, you have to experiment a few more times, you have contributed so much to the country, it's too late for me to reward, how can you be punished?"

There is still no stock, take another one, I still have to try, I want to see what the problem is, I must not let the soldiers go to the battlefield and say that it can't be used! ”

The old man was about to burst into tears after hearing this, he had lived in the Warring States with different nobles and lows all his life, and it was rare for a noble monarch to be as generous as Qin Zheng.

The old man hurriedly saluted and said, "Your Majesty! Thank you, Your Majesty, for your grace! There are still thunderstorms, we have made a total of three, and one of them has already exploded, so Xiaomin will go and get the other. ”

Qin Zheng nodded, the old man seemed to be dozens of years younger all of a sudden, and quickly turned around to look for it, and after a while, he took back a "Thunderbolt" that was almost identical to the previous one.

Then he lit another incense stick, respectfully handed it to Qin Zheng, and turned around and took the dud. Qin Zheng then smoothed out, put another "Thunder Thunder", and continued to order it.

As soon as the sound of "Zilazila" sounded, Qin Zheng immediately retreated into the crowd, and everyone was also ready, the lead became shorter and shorter, and finally entered the inside of the body.

"Boom!" A loud bang came, and the entire "thunderstorm" was instantly blown into dozens and hundreds of pieces, flying around, fortunately, everyone was far enough away and not within the explosion range, otherwise how could they be an iron hedgehog!

The old man had already taken his shield and stood in front of Qin Zheng, and he was relieved when he saw this scene, and Qin Zheng had already left everyone without being able to receive it, and stepped forward to observe the crater left by the explosion.

In fact, this copycat version of the Song Dynasty's "thunder" is quite loud, but the power is not so terrifying, and the explosion crater is not too big.

And the fragmentation damage of the grenade is very important, and this "thunder" fragmentation is still relatively not enough, not far enough.

Qin Zheng picked up one of the still hot fragments and analyzed: "It's okay to deal with a dense enemy. ”

The people next to him had already followed, and after hearing Qin Zheng's words, they couldn't help but worry about Great Qin's enemies, if this thing could explode in their dense formation, how terrible would the damage be?

Especially Zhao Gao, who had seen the thunder, thought that this thing was used on bed crossbows and trebuchets, wouldn't it really become a thunderbolt that could blast into the enemy formation?

At this time, everyone's eyes looking at the "thunder" were full of two words: "fear"!
