Early the morning of the second day, Cao Ergou, who had drunk the juice of artemisia, was as lively as ever, and Ouyang Xuan's body was not abnormal, but he felt that he was lightweight. He guesses it's because the fresh juice is rich in vitamins that are beneficial to the human body. After confirming that the artemisia grass picked was not poisonous, Ouyang Xuan instructed the soldiers who took care of Yu Zhu to squeeze out the juice of the remaining artemisia and feed it to Yu Zhu, and then arranged for someone to go to the mountain to collect artemisia again.

After Huang Dagen and the others further discussed the cooperation with Lu Dezhi and other elders, the various fires yesterday had already made sufficient preparations. Early in the morning, some fires have already moved, such as the industrial team, led by Chen Hu and blacksmith Li San'er, went to the blacksmith shop in the cottage to discuss the production of ironware. Regarding the titles of each professional team, Ouyang Xuan asked to change the name to "industrial team, mining team, business team..... because the profession not only has local fire personnel, but also copycat personnel. At first, everyone still called it "fire", but at Ouyang Xuan's insistence, everyone slowly got used to the title of "team". In the change of title, only Yang Xiu saw Ouyang Xuan's face not only for the sake of the cottage, but also his ambition, or the ambition to make a big career in this mountain.

Ouyang Xuan understands that the direction and principles of development are particularly important at the beginning of this career. He is determined to use his 21st century ideas and scientific and technological knowledge to guide the development of various professional teams. Because he understood that only technology could cope with the imminent large-scale invasion of the Mongols. During this time, he always reminded himself in his heart that it was May 1257 AD, and soon after, the Mongolian marshal Niu Ling was ordered to invade Sichuan, and in October, Liu Heima and others occupied Chengdu, and then the Mongol Khan Mengshouge personally conquered Sichuan. Only by arming ourselves with modern science and technology can we survive in this troubled era, can we call on and lead more people to confront the Mongols who are armed at an explosive level, and can we save more people from the iron hooves of the Mongolian army.

Ouyang Xuan plans to discuss with various professional teams one by one in the coming days to discuss the development direction and technical difficulties. Although he majored in chemistry, he was called a "little encyclopedia" by his classmates when he was a child, and he worked in the library before, and he also dabbled in the knowledge of iron smelting, steelmaking and forging, although some of the details are not very clear, but the general principles and key points are still remembered. Especially since he traveled to this troubled world, the dangerous environment and the pressure of survival have stimulated his potential, and the knowledge he has learned and dabbled in before has slowly poured out in his mind and gradually become clear after not eating, drinking, and being distracted by the bright lights. More importantly, he has a concept and vision beyond the millennium of this era, and understands the direction and general trend of development, which is the most important thing in science and technology and the development of industry. After all, research and innovation are hard, but imitation and imitation are much easier.

Ouyang Xuan's first discussion was the industrial team. The place of the discussion was chosen in the only blacksmith shop in Liuliba, and the owner's surname was Hu. Ouyang Xuan first took a closer look around the blacksmith shop, and the blacksmith Hu of Mu Ne followed closely behind, but he did not speak, but the deputy captain Li San'er made an explanation. In Ouyang Xuan's opinion, this is not so much a blacksmith shop, but rather a simple shed built by Blacksmith Hu next to his home, in addition to a large stove and iron hammers, anvils, a few iron hammers and iron tongs and other small tools, there are still a lot of rough iron, but the quality is very worrying. In addition to Blacksmith Hu, the blacksmith is his three sons, whose names are very easy to remember, respectively called Hu Da Hammer, Hu Er Hammer, and Hu San Hammer.

After looking at the blacksmith shop, Chen Hu invited Ouyang Xuan to sit down, and the rest of the people found a place to sit down in the shed. Ouyang Xuan saw that in addition to Chen Hu's ten people, there were also ten people from the village, and with the addition of Hu Blacksmith's father and son, there were 23 people in the industrial team. Except for the four blacksmiths Hu and his son and the deputy captain Li San'er, the rest of the people did not know how to make iron, but there were several carpenters, potters, etc., as well as a pottery master, which was the craftsman that Ouyang Xuan and Lu De needed at the beginning. It's just that the making of ironware is the top priority, and the topic starts with the making of ironware. Hu blacksmith father and son four introverted personalities, do not speak, the rest of the people said that the tools are unfavorable, the shape is rough, the product is not refined and other generalities, only Li San'er said useful improvement suggestions, such as equipped with sheepskin blower equipment, increase stoves, customized production molds and add a batch of forging tools. In the end, Li San'er also proposed methods to improve the quality of forging, such as frying steel and 100 steel, which was greatly admired by everyone, and Yang Xiucai, who was recording on the side, whispered to Ouyang Xuan that this Li San'er was a non-conformist person, and he was engaged in repeated innovations that caused the blacksmith shop to be damaged, and was sent to the government by the master because he could not afford to compensate.

After Li San'er finished speaking, everyone stopped talking, and Chen Hu asked Ouyang Xuan, who had been listening carefully, to speak. Ouyang Xuan briefly sorted out his thoughts and explained his considerations: first, in the place where the cottage was allocated to the residence of the officials and soldiers, and a place close to the stream that was easy to be dammed, a large blacksmith shop, a carpentry workshop, a hydraulic mill and a kiln workshop were newly built. The importance of the blacksmith and carpentry workshop is not overstated, and this water-powered mill can greatly improve the efficiency of sawing wood and save manpower, in addition to grinding grain. The dam was built here to store water, and the foundation was laid for the construction of a hydraulic calciner here, which was necessary for the production of fine gun barrels for mass production. As for the kiln workshop, it is used for firing pottery and charcoal, and it can also be used for burning coke after transformation. Second, according to what Li San'er said, immediately increase the number of stoves, blower equipment and forging tools. The third is to establish a quality control system, and a special person is responsible for testing the quality. The equipment made by the industrial team should be uniformly numbered and can only be used after passing the test. Especially in terms of custom molds, Ouyang Xuan emphasized that mold specifications and dimensions must be precise and uniform.

Ouyang Xuan especially emphasized that the coal from the nearby mines, that is, the charcoal in the mouth of the blacksmith, could not be used for forcination, but only charcoal. The main factors affecting the quality of steel are the impurities and carbon content in the iron, Ouyang Xuan just saw that the fuel used in the blacksmith shop is charcoal, which has a high sulfur content, and the local siderite also contains sulfur, so that the quality of the iron produced is very poor. In fact, coal is a very good fuel for forging because of its large output and high calorific value, but it must be desulfurized first and then turned into coke, which is the first choice for the production of high-quality steel, but now there is no desulfurization condition for the time being, so only charcoal can be used.

Everyone thought that although Ouyang Xuan was a monk before joining the army, although he had a broad vision, he must not understand the way of such craftsmen, but he knew that the content of his speech, the uniqueness of his vision, and the sharpness of his thinking were far beyond everyone's imagination, which not only surprised Chen Hu and others, but even the blacksmith Hu who had not spoken could not help but applaud, and everyone admired it in their hearts. At that moment, everyone refined and supplemented the matters raised by Ouyang Xuan, and put forward dozens of specific landing measures. When there was nothing new in his speech, Chen Hu ended the discussion. Ouyang Xuan asked Chen Hu to leave Li San'er and Hu Blacksmith father and son, and he wanted them to try out a few grenades. After everyone left one after another, Ouyang Xuan dictated the requirements for the shape of the grenade shell he wanted to build. Unexpectedly, as soon as he finished speaking, Yang Xiucai, who was beside him, asked suspiciously: "Brother Xuan, what you want to do is thunder?" ”
