Chapter 21 Grandma Zhang enters the Grand View Garden (10) to apprentice

Soon, the group came to the field. A few practical assistants brought out the iron, thermite, and other things and rearranged them.

Zuo Ci's apprentice Ge Xuan is now in charge of other research institutes, has his own research projects, and no longer acts as Zuo Ci's assistant. Liu Bei sent a few "assistants" to Zuo Ci for the purpose of stealing teachers, Liu Hou still thought that the manpower was insufficient, so he sent him a few more people, and now there are more than a dozen assistants in Zuo Cishi's room.

Generally, magnesium strips are used to ignite thermite, but now even aluminum has not been refined, let alone refined this metal whose properties are more active than aluminum, so Zuo Ci thought of a way, that is, to use gunpowder to ignite. For safety, in addition to sprinkling gunpowder on top of the thermite, Zuo Ci also took out a long lead and placed it on the test object. So that the person can light the fire 2 or 3 meters away.

It was still Zhang Xingcai who was holding a torch and preparing to light the fire, Liu Hou could see that Guan Yinping was also eager to try, but with her subtle character, of course, it was impossible to compete with Zhang Xingcai openly.

I saw that she pressed the torch on the lead without hesitation, and then quickly stepped back to everyone's side, staring at the test object 3 or 4 meters away with curious eyes. The lead sang a cheerful song and burned forward, and in a short time it reached the end.

I saw a "bang", and a fire rose on the iron, accompanied by a burst of black smoke, that is, the gunpowder was ignited. Then, with a "snort", a dazzling and brilliant spark bloomed. That's molten iron thrown around! Each beam of molten iron is projectile into the air for tens of centimeters, and then crosses a graceful parabola and sputters around the iron.

Countless parabolas spread out in all directions, forming a spark that is constantly blooming. The center of this spark emitted an unusually bright and dazzling light, and under the strong light, everyone couldn't help but squint their eyes, and they didn't even dare to stare at it for a long time.

"It's so beautiful!" Zhang Xingcai clapped his two little hands, jumped up happily, and his two eyes were completely bent into two eyebrows. Guan Yinping couldn't help but smile brightly, contrasting with the bright sparks a few meters away.

The spark continued to bloom for a while, and finally exhausted the last of its energy and gradually extinguished. The two little Loli ran over first, and when they were about to reach out to touch a bunch of black things in it, Liu Hou hurriedly stopped: "Don't move, you can't touch it, it's very hot." ”

Fortunately, he called in time to stop their reckless behavior and avoid injuries to their little hands. Otherwise, Liu Houzhen couldn't imagine what kind of scene their white and tender little hands would have been like when they touched this test object with a temperature of thousands of degrees.

The group gathered around, only to see that the middle of the large iron block was completely pierced, and a pool of red molten iron fell on the sand underneath, and as time passed, the red began to slowly fade, revealing a dark color.

The hole was surrounded by sputtered iron filings, the farthest of which was a step away from the hole in the center of the reaction.

Everyone was stunned, and their mouths opened in an O-shape. "This, this is terrible, it really burns through the iron in an instant. It looks like it's an inch thick. It was Zhang Xingcai who sighed first.

"Hehe, this is really comparable to Samadhi's real fire." Zuo Ci stroked his beard and smiled.

"Wow! That's great! It's amazing, it's amazing! Zhang Xingcai happily hugged someone's arm and jumped up. But this time it was not Liu Hou's arm, but Zuo Ci's. "Master Zuo, your spells are too powerful, teach me, you must teach me."

"Well, this ......, no......" Zuo Ci wanted to shirk, he was a research maniac, and he didn't want to waste any time elsewhere, if it wasn't for Liu Hou forcing him, he wouldn't even go to the school to give lectures regularly, and it would be even more difficult for him to accept apprentices. Otherwise, with his reputation as one of the three great immortals in the late Han Dynasty, there would not be only one apprentice Ge Xuan.

"Why not, you can accept Xiao Adou as an apprentice, why don't you accept me, hmph, don't you look down on me?" Zhang Xingcai crossed his waist, ready to explode.

But how can the apprentice have her attitude, so arrogant, so domineering, when she meets someone with a backbone, it is strange that she is willing to accept you as an apprentice. With Zhang Fei's status in Liu Bei's group, Zhang Xingcai's identity is not much different from that of a princess, which also causes Zhang Xingcai's unscrupulous personality.

But who is Zuo Ci, people even dare to tease Cao Cao and Sun Quan, and they still care about you as a little kid? That's right, in his eyes, Zhang Xingcai is no different from a little kid.

"This, accepting apprentices, is to pay attention to fate and Huigen's ......" Zuo Ci put his two hands behind his back, his wide Taoist robe fluttered with the wind, and posed as a fairy wind and bones, ready to talk eloquently, explaining the concept of fate and Huigen and the importance of accepting apprentices, so that this little kid can understand what is a master's demeanor.

"You just look down on me, huh!" Zhang Xingcai blocked back the high-minded talk he had prepared in one sentence. While speaking, he stepped forward and pointed at Zuo Ci's nose and scolded: "You bull nose, what's the big deal......

"Hmph, I don't know what to say!" Zuo Ci snorted coldly, waved his sleeves, brushed Zhang Xingcai's fingers away, continued to put his hands behind his back, and left the scene pretending to be a master in the world.

The person left the scene, and the person who scolded was gone, and the object of the scolding lost the meaning of scolding. So she had to stop scolding. "Hmph, what's the big deal, if you don't learn, you won't learn." Zhang Xingcai has no one to vent to, so he can only be angry with the things in front of him. I saw her angrily kick on the iron block with a hole in the middle of the test, but her foot jumped painfully.

Liu Hou frowned, and thought to himself: "This is not right, not only is it a barbaric girlfriend, but also a gentleman." If it continues to develop like this, will it become a bully of men and women everywhere when the time comes, and after the incident, I said that my dad is so-and-so. Something is wrong, I have to find a way to discipline her. ”

Secretly decided, Liu Hou walked up to the little female tyrannosaurus who was still squatting there and rubbing her sore toes, pushed the reverse bun on her head and said, "Get up, Master Zuo has promised to accept you as an apprentice." ”

"What? Are you serious? Didn't he refuse? Little Adou, how did you learn to deceive people? I saw Zhang Xingcai standing up after hearing Liu Hou's words, staring at him with burning eyes and asking.

"Really, why are you lying to you, didn't you listen to what Master Zuo just said, do you need fate and Huigen? It's fate that you see him, and Master Zuo is also asking questions to test whether you have Huigen. ”

"Where? When did he come up with the problem? Zhang Xingcai hurriedly asked.

"Didn't he just dump you with his sleeve? Then he walked away with his hands behind his back. What he meant was to ask you to go to the backyard to find him at a time of change. "Needless to say, this is Liu Hou's plagiarism of the Journey to the West where Sun Wukong and Bodhi Patriarch learn spells, but it is just changing three to one.

The shameless Liu Hou once again completely misinterpreted Zuo Ci's meaning and imposed his will on him. Zuo Ci can only lament in his heart, who wants him to be a real apprentice? Apprentices can only listen to the master's words, this is an era of respecting the teacher!

"Really? You didn't lie to me, did you? Zhang Xingcai looked at Liu Hou with a puzzled look. I can't think of how Zuo Ci can express such a rich meaning in those two strokes, is there such a far difference between himself and Xiao Adou? How can he understand the meaning of the old way, and he can't figure it out himself?

"Believe it or not, I believe it anyway." Liu Hou said, "If it's true, you can try it at night to find out." After speaking, Liu Hou arranged for a few female soldiers to take them back to the "Houlu" to rest. He hurried to find Zuo Ci in order to impose his will on him.

The process of persuading Zuo Ci was not easy, and when he heard Liu Hou say that he wanted to accept Zhang Xingcai as an apprentice, Zuo Ci was bitter and extremely reluctant. When he heard Liu Hou say that he not only wanted him to teach Zhang Xingcai scientific and cultural knowledge, but also to give her ideological and moral lessons to change her barbaric habits, Zuo Ci's face was bitter more bitter than bitter melon.

Zuo Ci was extremely dissatisfied with Liu Hou's arrest of him as a nanny, but he could only give in under Liu Hou's strong suppression. But he said that he was afraid that Zhang Xingcai would be brutal and would not be able to govern her. Liu Hou told him that he would use heavy rules to govern the troubled times, and promised him that he could treat her strictly.

Liu Hou's original words were: "You don't have to give me face, just die." As he said this, Liu Hou silently prayed for Zhang Xingcai and Zuo Ci, hoping that his chief scientific officer would not be tormented by his savage girlfriend.

As for how Zuo Ci reluctantly went to the backyard at the first watch (19:00-21:00) according to Liu Hou's wishes, pretended to appreciate Zhang Xingcai as an apprentice, and how he was angry with her and planned to give her a hard time, I won't say much here.

In short, Liu Hou is a matter of his heart, and he has taken a solid step in the cultivation plan of intellectual beautiful girls. laid the groundwork for a happy life after marriage.

Then, Liu Hou talked to Zuo Ci about aluminum for a while. When I learned that there was only a little bit of aluminum left, I also lamented in my heart. Although it is said that aluminum is a very useful metal, and in later generations it is the second largest metal after iron, but the little bit of aluminum that is left is useless at all, and Zuo Ci knows nothing about the refining method of aluminum.

Liu Hou knew that aluminum could be refined by electrolysis, but it was still very far from the electric era. "Looks like we're going to have to hurry up and get the electricity out." Liu Hou thought.

"Old Dao, I told you about electricity before, do you remember?" Liu Hou asked.

"Remember! It's the same kind of electricity as the thunder and lightning in the sky, I remember, is the master finally going to teach me how to surrender electricity? When Zuo Ci heard Liu Hou mention the electricity, he immediately became excited. Obviously, being able to subdue Thunder and Lightning has an infinite attraction for him.

"Five Thunder Righteous Method" is a Taoist supreme spell, in the eyes of the world's top Taoist Zuo Ci, this is undoubtedly a fairy method, and it is something that he dreams of. Now that "thunder" has been realized in the form of gunpowder, if you can still hold "electricity" in your hands, it is really a lifelong wish!

"If you want to refine this aluminum, you need electricity. You melt the calcined alum into water, an electric current is introduced, and aluminum is obtained on one side of the electrode. This method is called electrolysis. ”

"Well, that's how aluminum is refined, I see." Zuo Ci said, scribbling it down in his notebook.

Liu Hou knew that he didn't know the principle, so he explained:

"The principle of electrolysis is that the substances in the solution are all in an ionic state, and the ions are either positively charged or negatively charged, which you can understand as yin and yang. The incoming current needs to have two electrodes, one negative and one anode. The current flows into the negative electrode (cathode), and the positively charged positive ions in the solution migrate to the cathode and combine with the electrons to become neutral elements or molecules; The negatively charged negative ions migrate to another electrode (anode), donating electrons, becoming neutral elements or molecules. ”

"Why does the negative electrode attract positive ions and the anode attracts cations?" Zuo Ci asked.

"You can understand that the same sex repels each other, and the opposite sex attracts, just like a magnetic field."

"Uh-huh." Zuo Ci suddenly realized, and nodded while the chick pecked the rice and recorded it quickly.

"That's probably how it works, when there's electricity, you can figure out how to produce aluminum. In addition, this electrolysis method is widely used and can produce many substances, for example, electrolysis of water can get oxygen and hydrogen, electrolysis of salt water can get chlorine, etc., etc., you can study this slowly in the future. ”

It is impossible for Liu Hou to remember too many specific examples, so he can only point out a path for Zuo Ci, and more things need to be explored slowly. After all, scientific things take time to accumulate, and they can't be summarized in one or two sentences.
