Shi Tong took a bronze mirror, refracted a ray of sunlight from the outside, and shone on the jade porcelain tube: "This thing is only slightly transparent, you can just look at it." ”

Zhang Xiangzhong asked, "How can you not use glass?" ”

Su You asked, "Is there glass now?" ”

Zhang Xiangzhong pointed to the glass river outside the door: "Without glass, why is the river outside the city named?" ”

Su You was choked again: "Ahem, cough, cough...... I'm talking about high-temperature glass, which is a subject to high temperatures......

"This is the principle of pumping lead to smelt mercury and transporting it with fire......"

"Shut up! Uh, I'm sorry, I'm sorry...... Listen to me first, in short, this glass needs to withstand fire before it can be used...... Wow, let's get back to learning! ”

Zhang Xiangzhong finally shut up and nodded again and again.

Su You said: "According to the dream, water is synthesized from hydrogen and oxygen, which is a stable substance. If it is synthesized from hydrogen and oxygen, then in terms of valency, it can only be two parts hydrogen and one part oxygen, right? ”

Zhang Xiangzhong nodded and said, "That's the case." ”

Su You said: "Look, the two tubes of gas we have collected now ......"

Zhang Xiangzhongyi compared: "Two to one!" If the extrapolation is correct, this tube is hydrogen, this tube is oxygen! ”

Su You said: "Now that the gas has been prepared, let's test the activity of the two gases. ”

Seal the hydrogen pipe with your thumb under the surface of the water, move it to the furnace and let go, with a soft bang, a flame is instantly generated, and it disappears in a blink of an eye.

The firelight reflected Zhang Xiangzhong's face, and it was fleeting, and Zhang Xiangzhong looked sluggish: "This ...... That's gone......"

Su You said: "Look, with such a little hydrogen, the reaction is so violent, so it is a very unstable substance. Next, we experiment with oxygen. ”

The oxygen test was also very simple, and the burning stick was gently put in, and a bright fire ignited in an instant.

Su You said, "Brother, the experiment is done. Now we know that water can be electrolyzed into two substances, a phenomenon that can be called 'electrolysis'. After electrolysis, water becomes hydrogen and oxygen, which are composed of two to one, which is determined by their chemical valence. ”

Zhang Xiangzhong rubbed his hands: "The avenue lasts forever...... The avenue lasts forever...... This chemistry is the basis for my teachings. It can let the world know that the way of nature is all-encompassing, and only mediocre people do not notice it......"

After speaking, he paced back and forth in the room: "What the way of heaven is mysterious, and ordinary people don't know it, or think it's vain...... As everyone knows, the erosion of iron into rust and the burning of charcoal into ash are the principles of heavenly fortune, which can be deduced and proven...... Wait, quality has quantity, virtuous brother, this heavenly machine, or the quantity of material can be re-examined, right? ”

Su You admired the cleverness of this brother so much that he threw himself into the ground: "My brother has deep roots and can see through a word." ”

Zhang Xiangzhong looked up to the sky and laughed: "Hahaha...... Hurry! Hurry! ”

After speaking, he slapped the table: "In this life's career, you should complete this table!" ”

Su You waved his hand again and again: "Brother, this ...... It's too much, it's not a generation, so it's better for us to take our time......"

Zhang Xiangzhong thought about it for a while, and said with a smile: "The foolish brother has miscalculated, thank you for the guidance of the virtuous brother, I am almost about to fall into the demon path, and I will never recover!" ”

The two wiped their sweat together, and Su You said: "In fact, as long as you deduce it slowly, every time you find it, it will be of some use to the world, which is already very powerful." ”

"For example, this oxygen can support combustion, and ordinary charcoal can also burn. Can we speculate that there is oxygen in the atmosphere around us? ”

"If we increase the flow of the atmosphere and keep feeding new atmosphere into the flames, is that putting in a lot of oxygen to help burn? Isn't this the reason for the wind to fuel combustion? ”

Zhang Xiangzhong said: "Wait, according to your theory, after charcoal is burned, a new substance will be generated, which is very stable and will no longer burn, right?" ”

Su You smiled: "This experiment is easy to do, come on, let's do it again......"

After a while, Zhang Xiangzhong's eyes straightened again: "Brother Xian, I can also make the lime water turbid by blowing. That is, there is a fire burning in my body? Wait, is this the true fire of samadhi, which is the essence of man, the qi, and the gods in the body, all refined by this fire? ”

After speaking, he shook his head happily: "Dao Ke Dao, very Dao, famous name, very famous." The avenue is deep, and today you can see a hole, wonderful, wonderful......"

After speaking, he jumped up and rolled up the things on the table, laughed and said, "Buy and leave, these are all my Heavenly Master." The Taoist skills of the outcasts in the city will be given to the virtuous brother, and in a few days, there will be a good thing to send, and the foolish brother will go! Foolish brother go too! ”

The baby's steps were brisk, and he went out in a blink of an eye, and Su You hurriedly shouted: "Brother! Don't go wow! If you don't give them an account, how can they believe me? ”

A shiny thing was thrown far away from Zhang Xiangzhong's hand, crossed a strange arc, passed through the iron grid at the top of the door, and landed on the table in front of Su You with a "clanging bell", gurgling, and then lying down.

It was the silver gossip brand on Zhang Xiangzhong's neck before, Su You looked at the text on it, and the front was written "Zhengyi League, Sword Seal Fu, Impeachment and Summoning Hundred Gods, Yangping Dugong." ”

Flip over a line of small characters: "Awarded the twenty-seventh generation of Heavenly Master Zhang Xiangzhong, Fu Xuan is good at protecting chastity and Duanning." ”

Su You was startled, jumped to the door and shouted, "Brother, think twice!" Even if it is the Zhang family, pretending to be a heavenly master is also a big crime! On your brand, the word Mr. is missing! You can tell at a glance that it's fake! ”

I saw Zhang Xiang stumbling in the distance, and then Shi Tong, who had been petrified for a long time, was so frightened that he came back to his senses, and pulled Su You's back of the neck and lifted him into the room: "Come in, Master!" ”

"Uh...... cough cough ......" Su You's face was red and coughing again and again, and after standing still, he rubbed his neck with his hands: "You! You dare to deceive the teacher and destroy the ancestors! ”

Shi Tong knelt down with a puff: "Master, the apprentice is in a hurry, and he will be beaten and punished...... But, but the little fairy really can't be offended...... The one just now is really the Heavenly Master of this generation, my Dao Sect......"

Su You beckoned: "Get up and speak!" How to kneel at every turn! ”

Shi Tong stood up in a daze, and restrained his hands and feet: "Master, you ...... Are you alright? ”

Su You twisted his neck: "It's good to cover your mouth next time, don't you know that the child's neck is tender?" ”

Shi Tong bowed again and again: "Yes, yes, I won't dare to kill me next time." ”

Su You said: "You said just now, he is really Zhang Tianshi?" Why doesn't this sign have the word "sir"? ”

Shi Tong said: "It is true that the heavenly masters of all dynasties have the word Mr., but the heavenly masters of this generation, Dao Miao Xuantong, was only seven years old when he first met the official family, which is too young, so the official family did not give the word 'sir', which is ...... It's really not safe! ”

Su You couldn't help but smile dumbly: "So that's the case?" It's that simple? ”

Shi Tong saw that Su You was not angry, and said with a smile: "Isn't it that simple?" But things are simple, but people are not simple. ”

"This generation of heavenly masters, born in three months, can speak, in May. At the age of seven, he was summoned to Que, and now he is given to sit and consult, and the Tao is very wonderful, and he agrees with the will. Specially given purple clothes, sprinkled Chenhan, to the town of Futing. After the bundle of silk and gold vessels. This year's thirteenth, Yinghui is very, broadly versatil, especially Taoism. ”

Su You was stunned at the beginning when he heard it, and the rest didn't listen at all: "You can leave in three months, and you can talk in five months?" ”

Shi Tong nodded triumphantly, as if he was praising him.

Su You couldn't help beating his chest: "I knew that I would speak in March!" Maybe you won't need this broken name! ”

Shi Tong hurriedly comforted: "Master don't be jealous, although you are talented and intelligent, but after all, there is no Taoist immortal method, and the Heavenly Master has a method that has been passed down from the lineage, which is definitely different from Master's situation." You're good enough. ”

Su You rolled his eyes: "You know what I am jealous of when you understand something?!" ”

What I thought in my heart was that I had been worried for so long, and I didn't dare to let others know that I was too demonic, but as a result, this Great Song Dynasty was originally a world where demons were rampant!

Now relieved, rummaging through the sign: "So this is true?" ”

Shi Tongmei sneered: "Of course it's true!" In the future, there will be a record, you and the Heavenly Master today to discuss the elements of the Tao, peeking into the mysteries, will definitely bring a sentence, it is Shi Tong Shi Dazhi's attendant on the side, I am a big measure, but I am also a person in the history books. ”

Su You couldn't laugh anymore: "Ouch, you're so beautiful!" ”

Shi Tong picked up the rag and began to wipe the table: "This table has to be enshrined, the two division commanders preached at this table in the small shop, although I don't understand, but I just think it's amazing!" Absolutely precious......"

Su You finally couldn't listen anymore: "It's up to you!" I've got to go find those orphans! ”
