Even a rough man like Li Da shed tears, and while wiping it, he made excuses about why the wind and sand were so big.

Lu Xiaoyu hadn't experienced these things with them, and he might not have been able to comprehend the true meaning of this, and the Supreme Treasure on the side had already burst into tears.

"General, we are sad because we are touching the scene, why are you crying?" Li Yi wiped his tears and asked.

"I've had the same experience before, so I'm excited to empathize with it, and everyone laughs." Supreme Treasure wiped his tears embarrassedly and said.

On the contrary, Lu Xiaoyu stood up and comforted everyone: "Don't be sad and sad, although our ivory tower life no longer exists, isn't there a more important task waiting for us to complete?" If we can complete all these tasks wonderfully, the sense of accomplishment will not be less than the memories from before. ”

"Xiaoyu is right, let's follow the general to work hard, and this memory will be precious in the future, and the meaning will be even more far-reaching." Supreme Treasure said.

It is as if a new hope is being shown in front of everyone, and they are about to open the door of this new century and move towards a better tomorrow.

However, the Supreme Poke not only carried out a lot of reforms on people's livelihood issues, but also forgot that the purpose of their blitzkrieg was to relieve the pressure on the Henan People's Liberation Army, so as to achieve the result of occupying Wu Yue and attacking Xiang Yu on both sides. Therefore, a large amount of saltpeter and sulfur mined in Huaiyue before are still being made into explosive bags and shells in Huaiyue and sent to Jiangcheng County.

Now there is no need for the supervision of the Supreme Treasure, each step is completed by the craftsman of the assembly line, and there are special quality inspectors to do the final confirmation, so the probability of each shell and explosives package manufactured is very low, and each one is kept improving.

With these advanced weapons, coupled with the Supreme Treasure's reassembly of the armored combat vehicles that had been dismantled and used as the construction of the Shenji Cannon, the iron ore of the two cities was used to make the previously strong iron plates more unbreakable, and a full five armored combat vehicles were pushed into the barracks to open the way. The Shenji cannon inevitably blew up several times during the last two sieges, and then the Supreme Treasure ordered the craftsman to rebuild several Shenji cannons according to the drawings he took, but the problem of the explosion was never well solved, and the Supreme Treasure was also thinking hard about how to solve this problem.

Fortunately, the electronic encyclopedia he brought with him lived up to his hopes, and it clearly recorded how the problem of cannon explosion was improved in the Ming and Qing dynasties.

The first is the simplest thickened barrel, which is still easy to achieve, and the next is hollow water injection, cooling self-tightening. This method is more difficult to understand, and Supreme Treasure also deliberately flipped through the science and technology books brought by Lu Xiaoyu, and finally found an article that recorded this method.

Originally, the hollow water injection method was to set up an adjustable valve core in the inner hole at the water outlet hole of the upper body, and the opening of the water outlet hole was changed through the axial movement of the adjustable valve core in the inner hole of the upper body, so as to realize the adjustment of the water injection flow. The invention changes the opening of the water outlet hole through the axial movement of the adjustable valve core in the upper body bore to realize the regulation of the water injection flow. There is no need to repeatedly cast and fish tests, reduce the workload of fish testing, and ensure the success of the test and commissioning. The present invention can be compatible with the original water distributor structure in the use process, and the drive motor will not occur the phenomenon of blocked rotation, and the sealing ring located on the upper body and the lower body adopts a T-shaped sealing ring, and can prevent the sealing ring from falling off in the underground by being embedded in the T-shaped groove.

The third point is iron fan casting, which reduces porosity. This is easy to understand is to strengthen the level of craftsmanship.

The fourth point is to add iron hoops, that is, it is common to put iron hoops on the barrel to make it more firm.

The fifth point is to cast copper cannons, which have a low melting point and are easy to cast, good quality, and not easy to blow up, which is also what Supreme Treasure has been trying constantly, but at that time it was all bronze, and it was necessary to continuously improve the process.

There is also the iron cannon copper core, the reason is the same as above, the above methods can be achieved in the case of extremely low technology, but in the Ming Dynasty, the ancient people in addition to polishing, adding iron hoops, copper cannons and thickening, nothing else came up with it, especially to say that the iron fan casting was invented by the people of the Celestial Dynasty after the Opium War, it was the only place where the Celestial Empire artillery casting technology was more advanced than foreign countries at that time, the technology was extremely low, cheap and fast, and the effect was outstanding.

With this latest non-explosive technology, the efficiency of this magic cannon has increased by I don't know how many times, and I am no longer afraid of accidental injuries caused by exploding.

Everything was ready, and on the second day, when Master Guan and Supreme Treasure agreed on the time, the People's Liberation Army quietly sneaked into the land of Gaochun County after the Lin County Order took the county orders to Maoshan Yumai. And the entire Gaochun County was surrounded in a semicircle, leaving no gaps. On the other side, Li Da had already accepted the order of the Supreme Treasure, and with a thousand sharp knife troops, he came to the back of the Maoshan Yumai according to the map drawn by Liu Bang, which was the opposite direction that Lin County ordered them to come, so they would not notice it at all.

A large group of people gathered in a newly built Taoist temple on this mountain, and two Taoist children reported that Guan Daxian was refining pills inside, and it was a critical time. Lord Lin and the others didn't dare to make a loud noise, and quietly came to the alchemy room, and saw Master Guan wearing a Taoist robe and chanting words in a righteous mind, and holding a banana fan in his hand and incitement towards a stove.

Master Guan didn't seem to see Lin Xian order them to come, and he didn't come out to salute, but just closed his eyes and continued to refine the pill there. It's really a real person who doesn't show his face, and the more Master Guan pretends to be this kind of mysterious, the more people believe it.

"Xiao Tong, what are you doing now?" Lin Xian Ling asked in a low voice to the children who were protecting the Dharma on both sides of Master Guan.

The two little boys didn't know where Master Guan found them, they stood next to him very professionally, and when they saw someone coming in, they first put their index fingers to their mouths and signaled everyone to be quiet. At the same time, he replied in a low voice: "A few adults, please don't make a loud noise, my master is refining the pill, and it has reached the most critical step, if something goes wrong, you can't afford it, and the golden pill that you want to give to several adults will all be in the soup."

When the county magistrates heard that this alchemy had reached the most critical point, they naturally didn't dare to slack off, so they watched quietly on the sidelines so patiently, for fear of disturbing Master Guan, and Master Guan was concentrating on really alchemy there!
