As the saying goes, hard work pays off, on December 22, when Li Guanqi came to the Armor Research Institute again, he met Zhao Zheng and Gao Tiangong, who were beaming, coming back from the test site side by side.

"What's so happy? Speaking out also makes me happy and happy! Li Guanqi's smile was slightly far-fetched, it has been more than two months since the establishment of the Armor Research Institute, and it has always been like spending money, but until now the most valuable research results are just a new type of blower, plus the East Turk-Turks above the border pass are getting stronger and stronger, and there is a tendency to invade in a big way after the New Year, he wants to be a little unhappy. So for a while, he didn't come to the armor research institute as often as he did at the beginning, and the reason why he came here today was just because he was going to celebrate the New Year, so he came to appease everyone.

"Your Majesty is here?" Zhao Zheng and Gao Tiangong saw Li Guanqi at this time, and hurriedly wanted to salute.

"Excuse me!" Li Guanqi smiled slightly and said, "Ming'er is a young man, I will come to see you." By the way, if there is nothing important, Ming'er can let everyone take a day off. ”

"Huh? Ming'er is a young man? I've been busy with Lei Zhenzi's affairs, and I forgot the time. Zhao Zheng and Gao Tiangong smiled at each other and said.

"Lei Zhenzi? Who is it? Li Guanqi frowned, and almost didn't say the three words of the god list.

"Back to Your Majesty! Lei Zhenzi is not a human being, but a kind of firearm that we have newly developed. Zhao Zheng said excitedly, "I have tested it several times, and the power is very good, but we all think that the gunpowder formula still needs to be further improved!" ”

"You've developed powerful firearms?" Li Guanqi's eyes suddenly lit up.

"yes!" Zhao Zheng nodded and said, "The first test was successful seven days ago, and the power is very powerful. However, the cost is a bit high, so everyone is still working on improvement! ”

"Take me to see it!" Li Guanqi said anxiously. "And the test item, right?"

"Yes! Some! Gao Tiangong turned around and led the way, "After the first test was successful, we tried to produce a total of fifty pieces, and some of them were used in the past few days, and there are still twenty-two pieces. Judging from the tests in the past few days, the power should be no problem. It's just that the cost is really too high, and the cost of a thunderbolt costs ten taels of silver, which is enough for half a year's expenses for the villagers! So it's not practical yet, but we're working on it! ”

In front of Li Guanqi was a large black iron ball, the size of a watermelon, with a long fuse attached to it.

"This is Lei Zhenzi!" Gao Tiangong excitedly reported to Li Guanqi.

To be honest, the appearance of this Lei Zhenzi is indeed difficult to impress Li Guanqi, because both its size and weight are really a bit large, and it is difficult for a single soldier to operate. There is still a considerable distance from the practical firearms he imagined, at most they are landmines, and they don't know how powerful they are.

At this time, dozens of people had gathered in the test site, including Zhao Zheng and Gao Tiangong, who were extremely excited, and obviously they still had a sense of accomplishment in being able to invent this "Lei Zhenzi".

Li Guanqi didn't want to dampen their enthusiasm, so he nodded and said, "Let's start, let me see the power of this thunder shock!" ”

Zhao Zheng agreed, turned around and went to arrange for the sergeant to prepare the fire. Gao Tiangong turned around and saw that Li Guanqi was still standing in place. He kindly reminded: "Your Majesty, please stay away." It's best to cover your ears, this thunder shaker is too much......"

Li Guanqi shook his head and said, "It's okay, I want to look more carefully!" His current position was about a hundred steps away from Lei Zhenzi, and he didn't believe that Lei Zhenzi's power could reach that far.

A sneering lead sounded, and the sergeant in charge of the ignition immediately spread his feet and ran back, a few seconds later. An earth-shattering loud bang was heard, and a thick cloud of black smoke rose from the test site.

"Wow!" The people from the Armor Research Institute who were present erupted in cheers.

Li Guanqi rubbed his buzzing ears and grinned, this thunder shock was really shocked, just listening to the sound. It's no different from modern landmines, if not better.

But Li Guanqi still wanted to see the true power of this thunder shock, so when the smoke gradually cleared, he was the first to walk towards the scene of the explosion. When I walked to the front, I saw that the four dummies that were placed next to Lei Zhenzi just now had been blown to pieces, and if it was a real person, it would definitely not survive. However, the explosion was not ideal, Li Guanqi squatted down, carefully inspected the traces of the explosion, and found that the damage radius was only more than two meters, not even three meters.

"The sound is enough, but the damage radius is a little smaller!" Li Guanqi bit his lip and silently calculated in his heart, when suddenly a flash of inspiration flashed in his mind, and he got up and said to Zhao Zheng, "How long does it take to make a thunder shock?" ”

"If you have all the things, you can make one in half an hour!" Zhao Zheng immediately replied, "However, the current cost is still too high to be suitable for large-scale manufacturing!" ”

"I'm not going to make it on a large scale, I want you to make another additive!" A mysterious smile appeared on the corner of Li Guanqi's mouth and said, "I'm waiting here, you guys go and assemble another Lei Zhenzi immediately, and this time you will put some sharp little things in it, such as thistle terrestris and the like." ”

After listening to Li Guanqi's words, Zhao Zheng immediately showed a smile on his face, and nodded happily: "Understood, Chen understood!" There is no extra gunpowder for the time being, but the minister can take apart an existing thunderbolt and modify it. After speaking, I personally went to guide the craftsmen to modify Lei Zhenzi.

While waiting, Li Guanqi ordered people to re-place the human-shaped target in the test field, but this time he did not only put four, but several rounds.

Not long after the target was arranged, Zhao Zheng rushed over with a few sergeants who carefully carried a reprocessed Lei Zhenzi.

The effect of the second test explosion was as Li Guanqi expected, and the damage radius was increased by more than four meters, although it was not directly blown up at this position, but was injured by the iron thistle in Lei Zhenzi, and his life was worry-free, but in this way, the power of Lei Zhenzi was greatly enhanced.

Li Guanqi nodded with satisfaction, and said to Zhao Zheng: "Ming'er is a young year, I plan to invite the envoys of various countries in Beijing, and Abu will also come when he arrives." I hadn't thought about what gift to give to their Khan, but now that I've decided, I'll give this Lei Zhenzi! (To be continued......)
