"That makes sense! It doesn't sound like nonsense!" Taishang Laojun nodded, "Go on, have you encountered a blind spot in knowledge?"

"Okay, okay, I said, don't interrupt!" Huang Tongzi had a contemplative expression, "There are many ways to extract this oxygen, and the most suitable method for our immortals is water electrolysis and liquid air distillation......"

Huang Tongzi carefully recounted, and Lao Jun nodded after hearing it, "Such an important knowledge should be memorized backwards, speed up!"

Let's explain the principle of various chemical reactions, this water electrolysis is a decomposition reaction, uh...... This liquid air distillation is a physical method, and physics is another discipline, oops, don't worry, master, wait for me to turn the book~"

Paga slapped him again, "it, I can't remember this thing! Whether it's physics or chemistry, we need to understand it thoroughly! Will you learn more things will hurt you?" Lao Jun was so angry that he almost squirted out chili pepper water, "You kid has nothing to do and work hard, don't think about the beauties of the mortal world all day long! If you become a talent as soon as possible and take charge of yourself, what are you missing?"

"Spit out everything you've learned!" Lao Jun urged.

"Master, don't underestimate me, the first place in chemistry in the University of Literacy is me!" Huang Tongzi pointed his thumb at his brain when he said this.

"How many points?"

"Sixty!"

Lao Jun twitched his mouth again, and said in his heart, this blind university can't produce talents. As soon as possible, Lao Jun was very disdainful, Huang Tongzi still dragged his stomach to spit out half of the ink, and explained to Lao Jun all the subjects he studied in the University of Literacy. He is best at teaching chemistry from the periodic table and the most basic local programs, which are the basic knowledge of chemistry.

In the process of explaining, Huang Tongzi also wrote down the important content, which was a bit distorted, and the equation that lacked beauty gave people a sense of disorganization.

"That's all there is to it?"

"This is the chemistry knowledge of the third year of junior high school, and the next class will start to call it the first year of high school. Huang Tongzi's face was very red, obviously he was lecturing and being a master, but Lao Jun pointed out a big mistake on the side. What made Huang Tongzi puzzled was that the mistakes that Lao Jun found out were all made by himself in learning.

"Just learn such a thing?" Lao Jun was so angry that he slapped him and slapped him again, "You are still the first in chemistry, you make so many mistakes, and you will be embarrassed if you don't have the ability!"

After grinding in the Malatang shop for more than an hour, Taishang Laojun's small universe finally broke out, and expounded all the knowledge that Huang Tongzi said before, and all the knowledge was slow, and the things in the textbook were well combined with the common sense of the Three Realms. Everyone present was amazed, all of them had strange eyes, old prodigy!

"Ziyi, Lao Jun has spoken so well! Completely beyond the teaching level of a teacher at the University of Illiteracy!" Dong Yong took the lead in clapping his hands, looking at the old man in front of him with adoring eyes. Purple is also empathetic.

Min Jun's style of acting is obscene, the red clothes are like everyone's beautiful style, and the couple are heads and faces in the Three Realms. And Ziyi and Dong Yong are not so lucky, although the Jade Emperor promised them to live in the heavenly realm, but they can't set foot in the royal gate, the two can open this small shop in the food street or the queen mother loves her daughter to intercede behind her back. Dong Yongren is good in all aspects, simple, upright, and polite, but it is a pity that he is a mortal and cannot be appreciated and reused by the Heavenly Realm Royal.

"Lao Junda, you are amazing! tell everyone again!" Ziyi was like a little girl, cheerful. Other customers also clapped their hands excitedly and cheered for Lao Jun.

"Lao Jun, tell everyone again!" With a shout, he poked his head out, and the barefoot fairy walked in with two boxes ......of stinky tofu, "In the future, Lao Jun will be my only fart customer, and I will give these stinky tofu for free today."

Before the words were finished, the two boxes of stinky tofu from the barefoot Daxian had already flown back to the stall. Taishang Laojun's mana is boundless, but he really doesn't dare to eat barefoot stinky tofu.

Looking at the piles of believers who were eager for knowledge, Lao Jun sighed, "As the saying goes, people are ugly and study more! I want to applaud the students of the University of Illiteracy, and here I remind you that the knowledge taught in the University of Literacy is not a system, in fact, as long as you understand it, it is very simple! The mouth is a little dry, get me a bowl of spicy soup! I will give every customer a spicy hot pot of six yuan, which is counted in the old man's account!

"Thank you, Junda!" said Ziyi with a smile, and then hurried over. Dong Yong also hurriedly got out of the pot and filled every customer with food as soon as possible.

"Uh...... Boy in purple, let's put less chili peppers!" Several fairies and heavenly soldiers shook their heads, they didn't dare to fight with chili peppers as presumptuously as Lao Jun!

"Many of you will think that what you learn at the University of Literacy is too new and completely out of your understanding. Actually, no, they just changed their names. In addition, many things in the knowledge system of our immortals are planned in a very general way, and the university for literacy divides them into each subject. For example, the last time I did a water electrolysis experiment with Huang Tongzi, we just looked at the hydrogen with the naked eye, and we couldn't see any clues, but we used him in ignorance to make such a big move, and the alchemy room of Tushi Palace was destroyed in one fell swoop. While teaching, Lao Jun also glanced at Huang Tongzi with his spare eyes, and it was very clear who the word ignorance meant.

After a pause, Lao Jun stroked a handful of silver beards and continued: "Whether it is physics or chemistry, many knowledge points between the two are complementary to each other, and many knowledge points are subtly linked.

Huang Tongzi, who ranked first in chemistry, buried his head down, Master, you are hitting the confidence of the apprentice, you are speaking so politely.

Everyone also nodded, they only knew how to memorize the knowledge points hard, so pay attention to the problem? Besides, such a boring study can recruit so many students, all thanks to generous scholarships. The other is to improve their academic qualifications, and at the same time pretend to be forced, they will gild themselves with a layer of gold.

"Hehe, if the old man's guess is correct, the world in which this god of three thoughts lives is completely different from ours. I'm focusing on the macrocosm, and theirs is expanding into the onlookers' world. Lao Jun is a little stuck when he says this, and his understanding is really one-sided.

"Is the direction of progress in that world more bullish?" everyone has been led into the ditch by Lao Jun.

Looking at the person's expression, Lao Jun laughed twice, "The world is the same, different paths are the same!haha~"

"I just said that it's all this fur, and the old man is more interested in the knowledge points later. For example, the knowledge of hydrogen atoms is already hungry and thirsty, but the courses of this blind university are opening too slowly!" said Lao Jun with an expectant expression.

Everyone admired in their hearts, Lao Jun's learning ability was too terrifying, and after taking so many classes in the University of Illiteracy, everyone almost followed the rhythm in a fog. And Lao Jun just listened to Huang Tongzi, not only pointed out the mistakes, but also explained them one by one with vivid sentences

- Genius!

"This is the knowledge of another world, and it is normal for you to be uncomfortable. When you get used to this environment, it's actually quite simple. Lao Jun said.

"How do you know so much, Lao Jun?" asked Lu Dongbin.

"That's a good question. Lao Jun drank a cup of tea and continued, "All things are based on spirit, whether it is cultivation or not, alchemy ......."

"Master, master, let's talk about chemistry first. Seeing that Lao Jun was about to make a long fallacy, Huang Tongzi hurriedly interrupted.

"it! You're tired of hearing it, and everyone still wants to hear it!" Lao Jun scolded with a smile, "Have you ever thought about it, with the knowledge of thinking twice about God, I think there should be a specific discipline for people, otherwise it will be incomplete!" But why didn't he start a class?"

Lao Jun lowered his eyebrows and pondered for a long time, "Yes, it should be like this, it is impossible for God to give you all the things you have, and you still have a hand!"

Thinking about the gods is mysterious and unpredictable, Lao Jun can guess that the gods are already capable people, and everyone thought to themselves.

The Nine Heavens was originally a food street selling snacks, but it became the personal forum of Taishang Laojun. During this period, some ignorant questions raised by many heavenly soldiers and fairies were sprayed bloodied by the erudite and talented old man!
