In the golden autumn of October of 1341 AD, the grain in the territory was once again harvested, and Cheng Pan still sent people to voluntarily hand over this year's autumn expedition. Local governments in Jiangbei and Jiangnan completely turned a blind eye to the Cheng Pan armed forces. Of course, Cheng Pan would not suffer any loss. He handed over the grain on the surface and won the image of a good baby. In secret, Cheng Pan went out to do business every month, and doubled the food he sent. The transportation volume of 225 cubic meters also required several trains in later generations.

Based on the principle of making a fortune in silence, Cheng Pan began to lie dormant, waiting for the cultivation of junior science talents in the territory to successfully enter the industrial chain. So far, all the science and technology trees in the territory were learned by Cheng Pan from this era and explored and practiced step by step based on the information descriptions of later generations. Cheng Pan spent a lot of energy on this production system that seemed extremely crude in later generations, but with the development of the industrial system step by step, all aspects were constantly improved, the development of the science and technology trees had touched the knowledge system becoming more and more detailed and wider. Cheng Pan was an ordinary person after all, although he had passed the cruel college entrance examination in later generations. However, Cheng Pan's knowledge depth was not broad enough, and Cheng Pan had not worked in chemical factories, steel factories, and machinery factories. His personal brain power must be poor. Cheng Pan was no exception. Although Cheng Pan now practiced his internal skills, his energy was strong and his thinking was super fast. But a person could not take responsibility for the whole thing because of his cultivation of internal skills, his energy was strong and his thinking was super fast.

The technological progress of the industrial revolution. The rapid scientific and technological advancement in Cheng Pan's territory gradually stagnated. However, with the addition of a group of junior science and engineering talents, they took on breakthroughs in various fields, such as the establishment of steelmaking reflectors. Cheng Pan only mentioned this concept. Li He, the industrial group, and several newly graduated junior students completed the construction of physical objects after three months of hard work, further improving the quality of steelmaking. Cheng Pan improved the treatment of several R&D on the spot.

And the concept of patent fees was proposed. Every factory that uses this steelmaking technology, every ton of steel made with this technology will pay a sum of money as a patent fee to several R&Ds, which lasts for ten years. Why only lasts for ten years? Patent fees are a reasonable compensation for encouraging R&Ds to create new technologies, but they are not a tool for R&Ds to make money. If R&Ds can collect money for a lifetime and can be passed on to the next generation, then what is the difference between it and landlords sitting at home collecting rent?

Sun Gang was one of the first batch of disciples who passed the junior high school entrance examination. He studied the Department of Chemistry.

Cheng Pan is now talking to Sun Gang's research team. Speaking of this chemistry laboratory, it was built by Cheng Pan with gritted his teeth. It is not that the laboratory needs to be so luxurious, but that the chemicals in it have been used to waste Cheng Pan's various brains. Among them, hydrogen is made by the water-gas method. A reactor and ceramic conduit are produced by the water-gas method. A special porcelain burner requires a special porcelain burner to work for several days. Everyone in the laboratory has a set of full-body armor, which is to prevent various explosions in the laboratory. As a scarce gunpowder raw material, saltpeter, the consumption level of this laboratory is equal to a team of 100-person muskets. This laboratory also brought benefits to Cheng Pan.

Cheng Pan is now listening to their latest research results.

This is the thing. Last month, a furnace of iron produced by the steel group was found to be of excellent quality after solidification, and the tools produced could cut other steel. The steel group was ecstatic and began to summarize experience, but no matter how they adjusted the proportion of coal and iron and the time of release, this excellent steel only appeared intermittently and irregularly. Just when everyone was at a loss, a careful employee finally found that the iron ore that produced excellent steel was not locally produced.

.It was transported downstream from the upstream Jingxiang land, which is now Hubei. The steel team remembered the element theory mentioned by Cheng Pan and handed over the iron ore to the chemical laboratory. The chemical laboratory used a large amount of sulfuric acid and nitric acid tried to analyze the elements in it through the replacement reduction theorem. Finally, it turned it into a weak acid root with caustic soda and used hydrogen to reduce it, and then it was separated. By comparing the molar mass and referring to the periodic table of elements, its identity was determined.

Sun Gang was wearing a armor uniform and was reporting carefully: "Sir, the metal element is chromium, the outermost electron layer is three, that is, the positive trivalent, the molar mass is 52 grams and the density is 7.20 grams/cubic centimeter. It will greatly improve the quality of steel with steel. We have calculated that this alloy steel can only be cut with stainless steel stone."

After listening to all this, Cheng Pan said, "Can it be made in large quantities?"

Sun Gang replied: "This month, the foreign trade team discovered the origin of the iron ore and purchased a large number of raw ore. However, a large number of other ores of this ore are associated with it. They can only be produced in a small amount in the laboratory and cannot be produced on an industrial scale."

Cheng Pan continued to ask whether he had tested the best alloy steel formula.

Sun Gang took out a curve table and said, "This is a curve table that gradually increases the hardness and ductility of steel that are hard and ductility."

Cheng Pan carefully observed how many chromium elements are now.

Sun Gang said: "Now 16.351 kilograms have been made."

Cheng Pan said: "Give me six kilograms and discuss the rest with the industrial group to make cutting tools. Recruit people from the industrial group to expand the reactor, and use the laboratory method to produce small quantities to make high-quality tools."

Sun Gang: "Yes."

After discussing the production of chromium steel, Cheng Pan said: "How is the research on manganese steel?"

Sun Gang replied: "We are now experimenting step by step, but we found that the higher the content of manganese in the steel, the more brittle the steel seems to be."

Cheng Pan said: "Continue to experiment step by step, the properties of a certain proportion of manganese steel will become special."

When Sun Gang heard the eyes lit up, he said, "Sir, we will pay attention seriously."

Cheng Pan came out of the laboratory with six kilograms of chromium. The reason why Cheng Pan wanted these chromiums was only prepared to cast a weapon. Cheng Pan was very upset since the sharpness of the Yitian Sword last time. Although Cheng Pan defeated Mie Jue with clever sword technique, Cheng Pan's favorite way of playing was to fight head-on and put it against his opponent in a dignified way. Cheng Pan didn't mind the trick of taking tricks, but Cheng Pan would definitely not be willing to take tricks if he could openly. Cheng Pan had no choice but to use the mysterious power of the center sharp attribute of the Yitian Sword, but next time he had the chance to meet the magic weapon at the level of the Yitian Sword Dragon Slaying Sword, Cheng Pan wanted to use the hardness of the chromium steel to make several gaps in the magic weapon.

It’s just that only six kilograms of chromium cannot be made of pure chromium steel swords. If the chromium content is reduced, it is ordinary stainless steel. It is unrealistic for Cheng Pan to want factory-cutting weapons. Finally, it is adhering to the principle of using good steel on the blades of the ancients. Only high chromium steel is used on the blades. The sword body is made of alloy steel with 20% chromium. The sword body is used for 5 kilograms of chromium. It’s not that Cheng Pan doesn’t want to reduce the chromium content of the sword body. If the chromium is reduced to a certain level, it will not be resistant to corrosion.

When the steel was combined with the sword blade in the mold and gradually solidified, Cheng Pan suddenly put his hand on the red sword hilt. With a sting, a burnt smell appeared on Cheng Pan's hand, and the true energy of the sun quickly repaired the wound. Cheng Pan showed joy regardless of the scar on his hand. Cheng Pan found that he had just touched the hilt of his hand, a trace of sun power remained on the sword. Cheng Pan felt that he had discovered the method of manufacturing divine weapons. Cheng Pan was a practical school, and he endured the severe pain and started to do experiments.

After a while, Cheng Pan learned about the general situation. The power of the sun does not stay on the sword's body, but dissipates with the cooling of the sword body. However, the input of the sun's power is not without effect. After inputting the maximum amount of sun power, even if the sword body cools down, the maximum amount of sun power can be easily inputted. The input exceeding the maximum amount of sun power is the hotter the sword body, the better. In other words, the divine weapon made by Cheng Pan currently needs to be charged, unlike the mysterious force with sharpness that will not be reduced like the Yitian Sword. If Cheng Pan wants to expand the "battery capacity" of this divine weapon, he must bear the punishment of cannon-branding, and the spacing of cannon-branding cannot be long, otherwise the sun power in the sword body will have to be output to the top after it has dissipated.

This is a protracted battle. Cheng Pan's character is to be content with enjoyment. Cheng Pan usually considers such a chore. For a magic weapon, Cheng Pan decided to do it. Although he was burned and felt pain every day, he felt that the capacity of the magic weapon continued to expand. Cheng Pan gritted his teeth and persevered. People can constantly see their own results in doing things, which provides the motivation to continue to do things. But the process was too difficult. Cheng Pan wanted to give up several times. However, thinking about the cold light of the sky, and then the rewards generated by what he was doing and the suffering he suffered before, Cheng Pan decided to grit his teeth and fill the heavy sword in front of him to the limit. Cheng Pan decided to compete with it.

Cheng Pan has been in the sword-making room for three months, and Cheng Pan has all the things in the entire territory to the administrative group. He only makes decisions in the general direction. Cheng Pan keeps eating for three months, meditates under the sun, and then outputs the power of the sun, and takes out bits of time to read official documents every day. The power of the sun repairs the severely burned hands again and again, and Cheng Pan puts the recovered hand on the sword again and again. Finally, his hard work pays off. Three months later, Cheng Pan suddenly found that the capacity of the sword body reached a limit. Cheng Pan finally increased his strength and inputs the power of the sun. It seemed that the meridians were opened in the sword body, and the power of the sun was in the sword body.

A cycle formed in the sword body. The rolling sun power was moving in the sword body. The dissipation of the sun power dropped very slowly compared to the previous speed. Only one-twentieth of the uncirculated cycle. The entire sword seemed to have come alive. The injected sun power emitted a light golden light. Yes, the sword body was indeed emitting light. Cheng Pan tried the capacity of the sun power of the sword body, which had reached its limit, which was ten times the capacity of the sun power in Cheng Pan's body. Hard work pays off. In the past three months, Chang Pan has been tense in order to complete this work. In these days, both himself and people in the territory have advised him not to suffer such suffering, or to let him complete half of it.

That's fine, there's no need to do it so perfectly. Today Cheng Pan succeeded. Cheng Pan felt that his soul had been sublimated once, and his willpower had greatly improved. Cheng Pan had had this experience before, that was, he worked hard to repeat the college entrance examination for one year. He could not experience the joy of success without experiencing pain. Cheng Pan calculated the time and entered the power of the sun for the first time to succeed in 9981 days. Cheng Pan quenched and polished a series of processes such as heavy swords. The whole sword body was as bright as a mirror, and it deserved its reputation as stainless steel. Cheng Pan picked up the sword and observed that the sword weighed 81.3 kilograms, and the hilt was 1.9

The widest part of the sword body (not counting the guard) is twelve centimeters, and the thickest ridge is 3 centimeters. The outside of the sword body is chrome steel with 20% chrome content, and the inside is made of low-carbon steel and water. The blade is high-chrome steel. This heavy sword is not sharp, but Cheng Pan initially attacked the imperfectionism that caused a certain magic weapon to collapse several gaps, and the blade was opened. The whole sword and the hilt were all metal. The appearance was stainless steel (13% to 25% chrome steel) and looked very gorgeous. As for such a large piece of iron, it was a weapon to smash people, not to mention that it had a blade. Only Cheng Pan, a superman who could carry a ton of weight, could spread it.

Cheng Pan held the sword and walked out of the sword-casting room with a high temperament. The sun shining in the early winter was warm. Cheng Pan was stunned for a moment and then was ecstatic. If Cheng Pan's sword was filled with the power of the sun, it would take ten days to be dissipated in the sword-casting room before the power of the sun would be exhausted. However, Cheng Pan just discovered that the sword was in the sun. The total amount of the power of the sun was not decreasing but growing. Cheng Pan used a super sense to observe that the cycle of the sun's power kept going from the sword body illuminated by the sun to the supplement. The speed of this supplement was only one-tenth of that of Cheng Pan when practicing in the sun, but it was still objective. In other words, after two hours of illumination under the sun, the sword was fully charged. Cheng Pan was happy to find that this sword could be compared with the Dragon Slaying Sword in this way.
