Because on the day of the new year, he stayed with Liu Hanyan, but when he came back the next day, he was almost blocked by He Bijun, although he finally succeeded in hiding the truth, but he always felt a little sorry for this little queen! So during this time, Li Guanqi has been deliberately increasing the time spent with He Bijun, and Li Xiuxin is also deliberately running to Kunning Palace......

Therefore, when Xiao Ying ran to Kunning Palace to spread the message that Zhao Zheng of the Bingjia Research Institute was asking to see the emperor, Li Xiuxin's reaction was faster than Li Guanqi, and she stood up in a hurry, and she finally had the opportunity to meet her beloved man again.

"Zhao Zheng is here?" Li Guanqi stood up and said, "There must be some new progress on the side of the Armor Research Institute, and I will pass." ”

"I'm going too!" Li Xiuxin pursed her mouth.

"I'm going too! I'm suffocating to death every day! I'm going to go out with you for a walk! He Bijun also pouted.

"Huh? The Armor Research Institute is a military forbidden place, so it's inconvenient for the two of you, right? Li Guanqi said with a bitter face.

"No matter! You have to figure it out! The two beauties played the scoundrel in unison.

Li Guanqi had no choice but to let the two change into the clothes of the guards, mingle among the guards, and follow him.

What Zhao Zheng brought this time was great news - according to Li Guanqi's suggestion, the Armor Research Institute had successfully broken through another topic - hand-throwing firearms.

Zhao Zheng said with a happy face: "The ministers have made improvements on the basis of Lei Zhenzi. By refining nitrate, sulfur, and charcoal, and then testing their formulas, some people tried to increase the proportion of nitrate, and the result was that the power of gunpowder was greatly increased. We began to develop a smaller Lei Zhenzi according to the emperor's idea, and added iron beads to it. There is also pepper, which is very powerful and has a pungent taste...... We've also added a wooden handle to this small thunderbolt, so that the soldier can hold the wooden handle and throw it as long as the fuse is lit......"

"Did you really succeed in developing a grenade?" Li Guanqi was suddenly overjoyed!

"A grenade?" Zhao Zheng was stunned for a moment and said. "I haven't named it yet, I've been calling it Xiao Lei Zhenzi, but the name of the grenade ...... It's really quite vivid, good name! ”

"What are you doing? Hurry up and take me to see. When Li Guanqi heard that he had really made a grenade, he couldn't wait to rush over immediately.

When he came to the school yard of the Armor Research Institute, a sergeant held a firearm that had just been named "grenade" by Li Guanqi and lit it. I threw it out hard, and I heard a loud "bang", a cloud of black smoke rose, and a pit appeared on the ground.

Li Guanqi stepped forward, took a closer look, and found that this grenade had the same problem as Lei Zhenzi - the movement was large, and the power was small. Although gunpowder has been further improved, it is still far from powerful. And judging by the effect of the explosion, the shell of this grenade is almost split in two. So there is no shrapnel killing.

"Hey, it would be nice if we could research butter explosives, the power of black powder is still limited after all!" Looking at the traces left by the grenade explosion in front of him, Li Guanqi let out a sigh. But he also understood that in the current state of the times, he wanted to succeed in inventing butter explosives. It's almost impossible. He remembered that he needed glycerin, nitric acid, and sulfuric acid to prepare butter explosives. Glycerin is okay, but the key is where do you get nitric acid and sulfuric acid?

After thinking about it carefully, Li Guanqi realized that perhaps he had let the Ordnance Research Institute focus on firearms research, which was indeed fueled by the seedlings. Due to the conditions, thunder shocks and grenades are almost the most powerful firearms that can be invented in this era.

"Hey! What are you thinking? Not a word! A guard standing behind Li Guanqi asked in a low voice.

Zhao Zheng was stunned for a moment when he heard it. Xindao: Why is this little guard so big and small? actually dared to talk to the emperor, but he was also concerned about Li Guanqi's opinion on this grenade, so he didn't care much, but asked Li Guanqi: "Your Majesty, how is this grenade?" Can it be used in real combat? ”

Li Guanqi came back to his senses from his contemplation, and asked instead of answering, "How much does this grenade cost?" ”

"Almost five taels a piece!" Zhao Zheng answered cleanly, obviously having done the corresponding accounting in advance.

"This thing is thrown out and gone, and considering the various protections in the transportation process, the cost of this is still too expensive!" Li Guanqi let out a sigh, and then asked, "If I prepare for your mass production, how much can the output reach?" ”

"If the manpower and materials are up to date, about 1,000 pieces can be produced every month!" There was a little excitement in Zhao Zheng's tone.

Li Guanqi nodded lightly and said: "Then produce three thousand pieces first, and then produce another three hundred Lei Zhenzi filled with new gunpowder, after the production is completed, all of them will be transported to the front line, and Hedong, Guannei and Longyou will each be equipped with a thousand grenades and a hundred Lei Zhenzi." ”

"Yes!" Zhao Zheng replied excitedly. Since he played him to return to Li Guanqi, he finally has real credit.

"You have to be careful when transporting it, so you don't have an accident. In addition, you should send someone to the front line to act as an instructor and guide them on how to use it, so as not to accidentally get hurt! Li Guanqi instructed again.

After arranging the grenade and Lei Zhenzi, Li Guanqi gathered Zhao Zheng, Gao Tiangong and other elites of the Ordnance Research Institute to hold a technical exchange meeting, and re-issued a new task -- gunpowder research continued, but the process of firearms development was suspended, and the focus of the work of the Ordnance Research Institute should first be shifted to ironmaking and steelmaking.

Li Guanqi has poured out all the memories of blast furnaces, open hearth furnaces and blowers in his previous life, although it is only a very rough framework, but now he can only hope for the common wisdom and efforts of these elites.

At the end of the meeting, Li Guanqi hesitated for a long time, but still brought up the matter of butter explosives, although he didn't think that it could really be developed successfully in this era, but it was always good to have one more research direction, besides, what if it succeeded......

After finishing his business, Li Guanqi smiled and said to Zhao Zheng: "The scenery here is good, I want to travel to the mountains, you can be a guide, right?" ”

"Huh?" Zhao Zheng was stunned for a moment, and asked suspiciously, "Didn't Your Majesty see it before?" And now there is snow on the mountain, there is nothing to see! ”

Li Guanqi glanced at a guard next to him, and said with a slightly wry smile: "It's this snowy scene in the mountains, I haven't appreciated it yet!" Don't be wordy, let's go!" (To be continued......)
