"I congratulate the 14th Prince on his appointment as the title of king!" After a day and night, Nan Mingren and his group finally caught up with Yinzhen and entered the house. Nan Mingren congratulated Yinzhen with a smile on his face.

"Haha! Lord Nan, when did you learn this set of common etiquette? Since you said that, I would like to thank you!" Yinzhen saw Nan Mingren congratulating him and couldn't help but make fun of him first and then accept the gratitude from the foreigner.

"Master Nan, how many small artillery pieces have been brought this time!" Yinzhen said with a serious look when he looked at Nan Mingren in front of him.

"Fourth Prince, this batch of artillery was built in a very hidden mountainous place under the capital firearm battalion. I have supervised the construction of thirty-two of them, of which only twenty-two were qualified, but after artillery experiments, only fifteen finished products, and the shells were almost passed the full mark!" Nan Mingren said to Yinzhen in front of him with a serious face.

"It's hard to start with! The first casting will inevitably lead to some failures. But your General Administration of Fire and Machinery Manufacturing needs to continuously improve and explore. Also, I have sent all the experts and craftsmen who have withdrawn from Suzhou, Jiangning to the Northeast. They will go to the northwest region with me in more than three months. Don't go back, just enjoy a rare holiday with me here!" Yinzhen said with a smile to Nan Mingren in front of him.

"I obey the order!" Nan Mingren bowed to Yinzhen in front of him and replied.

"Let's go! Let's see how powerful the mortars built through hardships!" Yinzhen said, then said to Nan Mingren in front of him and walked out. Nan Mingren walked out immediately.

"Hello, brother-in-law!" Zhou Ze saw Yinzhen coming out of the room and greeted him enthusiastically.

"What I didn't expect about this mission was that you were escorting here. Why is it very hard?" Yinzhen looked at Zhou Ze in front of him and patted his shoulder with a little surprised smile.

"It's okay! I didn't feel tired, but I just didn't know what was inside, and I was a little curious!" Zhou Ze said curiously at Yinzhen in front of him, looking at the three carriages that had been surrounded by the Zhengbai Banner Army.

"You move all the boxes in the car! Remember that the boxes in the two carriages at the end must be taken care of easily! If you have any negligence, behead them all!" Yinzhen said loudly at the Zhengbai Banner soldier who was carrying the boxes in front of him and looked at the scene in front of him with a nervous expression.

"Zhe!" The soldiers of Zhengbai Banner saw the serious Zhengbai Banner soldiers who saw their prince who rarely spoke harshly in front of them and couldn't help but feel serious and responded loudly.

"Bang!" Yinzhen came to the box that was unloaded from the first car, bent down, pulled out a dagger from behind the boots, pried open the box, and saw what he wanted to see. He couldn't help but reach out and took out the long cannon barrel from the box and assembled it according to the steps he saw in later generations in military books. A quarter of an hour later, a strange cannon was born in Yinzhen's hand. At this moment, the strange cannon was tilted toward the sky with its neck tilted towards the sky.

"You two bring that box over." Yinzhen looked up and saw two flag soldiers unloading the last shells, and waved their hand and summoned them over. When the two put the box on the ground, they imitated Yinzhen's actions and pulled out the dagger and pried it open along the gap next to them. They peeled off the oil paper and presented it to everyone. Yinzhen took out a shell from it, weighed it first and said to the people behind him.

"Everyone retreated and left me at least ten steps away!"

"Zhe!" All the soldiers of Zhengbai Banner looked at each other first and immediately executed the order.

"Bang~" I saw Yinzhen holding the shell in both hands and sliding the shell into the cannon barrel. I saw a smooth chamber sound, then I saw a beautiful parabola forty or fifty meters away from him, and then there was a burst of explosion of earth and rocks cracking. I saw the cannon barrel in front of Yinzhen spraying with radiation medicine and slight smoke.

"Well! The quality and power are really nothing to say! Master Nan, your Fire and Machinery Manufacturing Bureau has made another great contribution this time!" Yinzhen stood up and said happily and satisfied to Nan Mingren who had already jogged in front of him.

"It's just a pity! The output of this mortar is really too low! You have to know that this mortar is a powerful weapon on the battlefield in the future. If the output is so low, how can it meet the needs of the battlefield!" Yinzhen complained solemnly to Nan Mingren in front of him.

"Fourth Prince, you also know that the production of this kind of cannon is quite time-consuming and requires a large amount of labor to transport saltpeter, steel and a lot of materials. In addition, the steel made of this batch of mortars was transported from Jiangning, and the transportation route is very inconvenient, so I can only let them transport more at once, but it still cannot withstand the consumption! Not only that, our technicians can only rely on a few short people transferred from the Ministry of Works, which are all the costs that restrict the production speed of mortars!" Nan Mingren said with a grievance, and pointed out the disadvantages in front of Yinzhen.

"As long as I solve all the problems you mentioned, how many mortars can you create for me!" Yinzhen asked with a serious look at Nan Mingren in front of him.

"There are at least 300 balls per month and there are more than 50,000 shells, but these three conditions are not easy. In my opinion, it is better for Your Highness to act carefully?" Nan Mingren was a little embarrassed to always find problems for Yinzhen, but when he saw Yinzhen in front of him, he couldn't help but follow his ambitions, but he still advised him.

"You don't have to worry about this matter. Just do what you said. Lang Tuo. Summon five Niu Lu's Ezhen to gather the flag soldiers who had used red cannons in Niu Lu immediately form a separate temporary system. Lord Nan Mingren personally teaches the use of this cannon. There are also precautions. This newly established team only needs 45 people, and no one person is missing!" Yinzhi first said to Nan Mingren in front of him, and turned his head and said to Lang Tuo, who was full of nervousness on the side.

"Master Nan, these forty-five people can be said to be people who know artillery calculations, so please worry! As long as they are taught, they will drive the next group. Over time, a considerable artillery unit can be established. Although it is still a long time now, it will definitely be realized in the future!" Yinzhen said seriously to Nan Mingren in front of him, but a firmness revealed in his eyes that made Nan Mingren, who wanted to say something, swallow it back.

"I will definitely do my best!" Nan Mingren replied respectfully to Yinzhen, who looked confident.
