Five days after the No. 2 blast furnace was put into operation, Cheng Pan gathered the blacksmith group in a classroom, and as Wang Tianzhu's outsourcing team continued to recruit people, Cheng Pan now managed a thousand people to eat. The blacksmith team has also been expanded to 8o people. Some of them are new recruits from the young men, and some of them are students recruited from the academy. As a result of the cooperation between the education group and the various groups to run night schools, the literacy rate of Cheng Pan's subordinates has been greatly improved, and Cheng Pan has made great efforts to compile a simple simplified Chinese pinyin dictionary, and after several transcriptions, each working group has a copy. Although most of the obscure words are not included, this dictionary is indeed a tool for literacy.

Eighty percent of the blacksmith group in front of Cheng Pan got rid of the illiterate hat, and the rest of them were also hurrying to study, because once they passed the guò character assessment, their wages and benefits would be higher.

At this time, Cheng Pan began his flickering teaching again.

"Don't hide it from you, I was adopted by my master when I was born, my master is a master who adopted me when he was already 13oo years old, he has gone through the practice of qi, building the foundation, knotting the Dan, Yuan Ying, distracting the gods, and after the three great realms of cultivation through the three great realms of heavenly thunder, karmic fire, and Xuanfeng, he does not jump out of the five elements in the Three Realms. Not controlled by the gods and Buddhas. When he was about to step into the immortal realm, there was a trace of heaven and earth. Cheng Pan looked at the bottom and listened to his nonsense with relish, secretly thinking that his own teaching was still quite able to concentrate the students' attention. So he went on to compile "Although the family master has practiced for thousands of years, a trace of the Great Dao is so rare that even the Buddha and the Jade Emperor and the Three Qing Dao Ancestors want to seek the Great Dao but can't. What the Great Dao is is the law of the universe. Why did the tutor see this avenue? It turns out that this is due to the competition between humanity and heaven, the way of heaven is the embodiment of the will of heaven and earth, heaven and earth will not let a certain race be strong all the time, it will shroud the luck in which race, which race will rise, once a certain race is too strong, suppressing other races, the way of heaven will rain disasters, the dragon clan, the witch clan, and the demon clan are the protagonists of heaven and earth, but they all suffered unforeseen disasters because they were too strong" Cheng Pan looked at the people below talking about the way of heaven, and they all showed awe, and then his voice mentioned, "But, what is humanity, Humanity is the unremitting will of self-improvement left by the ancestors of the human race from generation to generation. The people below felt a little unnatural when they heard this, it was the unnaturalness of the conflict between the ancestors and God. "Why does the struggle between heaven and humanity allow the family teacher to see through that trace of the avenue?" Cheng Pan whetted the appetite of the people below and said, "Because humanity wants the human race to know that trace of the avenue, as long as the human race understands that trace of the avenue, the human race will become the protagonist of heaven and earth without cultivation, and completely and forever dominate the position of the protagonist of heaven and earth. After learning the cause of the conflict between humanity and heaven, the tutor resolutely dictated this avenue to me. Let me pass it on to the Terrans. Just after the master's last preaching, because the master was deeply favored by heaven and earth, after betraying the way of heaven, he was punished by heaven and was swallowed by his own mana and died and was reincarnated under the protection of humanity, and I did not practice the art of immortality, my own yang life was long, protected by the law of the great avenue, and the way of heaven could not help me. Cheng Pan continued, "Now I will pass on this silk road to you, and you will pass it on to students more in the future."

At this time, one of the blacksmiths below said: "Young Master Cheng, although the sages, that is, humanitarians, hope that we will accept the teachings, but will this make God angry and thunder and smash us?"

For a while, everyone thought of this and looked at Cheng Pan. Cheng Pan thought, "Make up a mythical story to make these buns pay more attention to the discipline they teach, but it seems to have gone too far and scared them." Cheng Pan continued to flicker, "Don't worry, if the Heavenly Dao wants to punish people, it must be in accordance with the rules, you are all mortals, and you have no mana, and you have not received the additional benefits of the Heavenly Dao." Although you eat and drink water by the grace of the Heavenly Dao, this is what the Heavenly Dao should do. If the Heavenly Dao does this, it will be incompetent, and it will violate the Great Dao and will be punished by the Great Dao. Now not only does the Heavenly Dao not dare to punish you, but even your luck does not dare to diminish. As long as you pass on the great road I have given you to more people, you will enjoy the incense of future generations after a hundred years." After flickering through the last knot in the hearts of the blacksmiths. Cheng Pan began to preach.

"Everything in heaven and earth is made up of vital energy. Genki is made up of Genko". Speaking of this, Cheng Pan pointed to the periodic table of elements that had already been drawn on the blackboard (this table was originally printed on the clothes he had crossed) and said: "Now there are more than 200 yuan in heaven and earth, and there are unknown yuan in the back of more than 200, but the time of these yuan in the world has dropped sharply from decades to a few moments, and the life span of the yuan in the back is shorter, so it is not marked in the heaven and earth yuan table."

In everyone's amazement, Cheng Pan continued, "Is it Jue, there are many kinds of heaven and earth yuanzi, but these hundreds of yuanzi are all composed of three substances."

Cheng Pan continued to throw out the fierce material "Yin, Yang, and neutrons make up each kind of yuanzi".

"Each nucleus is divided into the inner nucleus and the outer nucleus, in which some yang and neutrons are closely combined to become yang neutrons. Yang neutrons and neutrons together form the nucleus of the atom. Since all things in heaven and earth are in harmony, the number of yang neutrons in the nucleus and the number of yin in the periphery are the same. ”

Cheng Pan pointed to the periodic table again and said, "On this table, the number of internal yang neutrons and neutrons in the core of each type of element has been marked."

And for each kind, the yin outside the yuan is also arranged according to the law, the smallest yuan hydrogen helium outermost layer of electrons are one and two respectively, to the second column and the outermost layer of the last column up to eight. Of course, if you want to understand the specific electron shell arrangement of each kind of atom, I still have 200 specific diagrams, and I will tell you about them after class. ”

"These two hundred elements can be combined with each other, just as water is composed of hydrogen and oxygen"

At this time, the person below chimed in, "I thought that water was made up of a single element."

Cheng Pan was glad that someone could keep up with his rhythm and said, "Water is still relatively simple, and civil engineering is composed of millions of substances, each of which is composed of a variety of elements, which will be discussed later."

Cheng Pan continued, "Let's talk about iron ore, iron ore is composed of oxygen and iron yuan, of which the outermost yin of iron is six, and the outermost yin of oxygen is two. They use the outermost yin to make the outermost yin of each yuan reach the perfect number of eight. ”

Cheng Pan drew the electronic bonds of ferric tetroxide on the blackboard

Then he said, "The main component of coal is carbon, which is a kind of element. Its outermost electrons are four. At high temperatures, carbon reacts with oxygen molecules to form carbon dioxide and carbon monoxide. Cheng Pan drew the chemical bonds of the two molecules.

Cheng Pan finally said, "The oxygen yuan was taken away, and only the iron yuan was left, and the tens of millions of iron yuan were the molten iron we smelted, and this process is a chemical reaction, and the name of the avenue I passed on is chemistry."

Everyone who heard this place had a feeling of entering the Tao from art, and in the middle of the following month, Pan kept talking about chemistry. None of the content goes beyond high school chemistry. However, the chemistry mentioned by Cheng Pan is already a complete system of disciplines. In the future, those who studied chemistry have also heard the teacher tell the second-rate myths and stories compiled by Cheng Pan, and the previous generations of chemistry researchers have been passing on chemistry to as many students as possible with the attitude of passing on the torch. As new materials are developed, the charm of chemistry blooms. Everyone reread this myth. Whether this myth is true or not, chemistry is indeed a glimmer of avenue for human beings to dominate the world and dominate the world.

Two hundred years later, the world has entered the information age. And the origin of chemistry has always been a mystery. One of the biggest doubts is how Cheng Pan came up with a complete periodic table of Yuanzi and how he knew the specific structure of Yuanzi in such a poor era. Some of these radioactive elements have only emerged in recent decades. The last two Yuanzi, who were not named by Cheng Pan back then, only recently appeared in the real yàn room. Could it be that Cheng Pan's master is really a true immortal?
