"This ......" Taishang Laojun hesitated, Liangchen, it's not that I look down on you, it's really your identity as a second-grade pharmacist here, how can I communicate with you?

Liangchen knew that Taishang Laojun was hesitating, if there was a tool to conduct a field experiment, he could definitely blind the eyes of all immortals, but he also did not have the tools to conduct an experiment on the spot, so he had to use theoretical knowledge to win the trust of Taishang Laojun.

"Lao Jun, let me ask you, do you know what kind of gas is here?" Liangchen grabbed a handful of void in his hand.

"Immortal energy, aura, ordinary gas for breathing. "Taishang Laojun is very strange, such a simple topic, do you look down on my wisdom?

Liangchen shook his head, "No, no, there is indeed immortal aura, but the ordinary gas you said actually contains a variety of gases, and the overall mixture is called air, which is divided into oxygen, nitrogen, carbon dioxide and other gases." Oxygen is the gas we need to breathe in, while carbon dioxide is the gas we exhale. ”

Immortal aura is too thin in the human world, anyway, the current technology in the human world has not been detected.

When Taishang Laojun heard this, the air was easy to understand, but it was really the first time he had heard of oxygen, carbon dioxide, nitrogen, etc.

Just this point, Taishang Laojun changed his opinion of Liangchen, although he didn't know what Liangchen said, but listening to his nouns was so professional, it didn't look like nonsense, so he believed eight points!

"It turns out that I'm lonely and unheard!Liangchen, why don't you accompany me to my Tushi Palace, and we can study and study it well?" Taishang Laojun was itching in his heart, he was very interested in new knowledge, which was related to the refining of the super-grade elixir.

Even if you can't learn a better way to refine a super-grade elixir from Liangchen in the end, you can also refer to it and improve the current alchemy method!

"This, I still need to see the store here, and it's not easy to doppelganger. "Liangchen had no choice but to say, Tushi Palace, it must be in the Heavenly Court, the place where Taishang Laojun refines pills, and this is also a great opportunity to make friends with Taishang Laojun.

"You don't need to worry here, Ling Feng, right? He will give me face, and with Jingwei and Xiao Er here, you don't have to worry. "Lao Jun is too anxious, can you be more anxious than the great cause of alchemy?

Liangchen was shocked when he heard this, this breath is so big! And how can Lao Jun still know Ling Feng? Mom, it seems that Ling Feng's backstage is not ordinary!

But...... "What about the Heavenly Court?" Liangchen is a little immortal, who belongs to the lowest level, where is he qualified to enter the Heavenly Court. It's like a small merchant in ancient times who was not qualified to enter the palace.

Who knew that Taishang Laojun said, "You don't have to worry, I will take you to my Tushi Palace, and the Jade Emperor will not dare to ask!"

Hiss...... It seems that Taishang Laojun is not a courtier of the Jade Emperor, but in this heavenly court, Taishang Laojun has no quarrel with others, and he doesn't care about power. And he is one of the Three Qings, if he is placed in the human world, he is a retired power, and the Jade Emperor is the one who really governs/governs/governs/governs.

"Alright, I'll go with you. "Liangchen has decided, Tushi Palace is such a good place, the alchemy room, maybe you can pick up a few elixirs, and there is a great god of Taishang Laojun covered, what are you afraid of?

Luck is too good today, isn't it? Three great gods have visited in a row...... Ignore Jingwei's girl, she's a child.

"Let's go now. Taishang Laojun grabbed Liangchen's hand and swished, Liangchen felt that in the blink of an eye, he actually appeared in a completely unfamiliar place.

Damn, didn't you say that you were going to pass through the East Heavenly Gate, that is, the gate to enter the Heavenly Court? Why didn't it seem to stop?

But Liangchen didn't know that Tushi Palace was actually not in the Heavenly Court, and Tushi Palace was located in the Thirty-third Heaven, which was the residence of Taishang Laojun.

And you don't need to go through the East Heavenly Gate to go to Tushi Palace, so naturally you don't need to stop. As for what to do when Liangchen asked Heavenly Court before, Taishang Laojun thought that Liangchen was worried that he would be questioned by the Jade Emperor when he went to Tushi Palace.

The Jade Emperor is in the Nine Heavens, and he is not qualified to manage the Thirty-Three Heavens.

Look at this Tushi Palace again, the palace is very large, resplendent in gold, five and then rise, supported by nine pillars, symbolizing the imperial palace of the Supreme of the Ninety-Five!

And the surroundings are very empty, and there are three huge Ding furnaces in the middle, to be precise, Dan furnaces. One golden, one silver, both of which are used for alchemy. In addition, the largest one is called the Bagua Furnace, which can be used for both alchemy and refining tools, such as golden hoop sticks, nine-tooth nail rakes, etc., all from this Bagua furnace.

In Journey to the West, Sun Wukong was used by Taishang Laojun to refine the pill here, but it made Sun Wukong refine his fiery eyes, right?

I don't know if I can also jump in and practice, can I refine my fiery eyes? Liangchen thought about it, but felt a chill down his back, or forget it, he is so weak, I am afraid that he will be wiped out as soon as he touches that samadhi true fire.

"Liangchen, tell me now what oxygen is, what carbon dioxide is, and what nitrogen is. "Taishang Laojun is eager to study.

"This ...... "Liangchen is so helpless, Lao Jun, where can you let me find oxygen to show you at this time? You don't have any tools here."

However, carbon dioxide should be relatively easy to obtain. "You prepare me a couple of transparent containers, water, and lime. ”

Taishang Laojun changed his hand casually, and all the things that Liangchen wanted were done. Liangchen secretly stammered, a great god is a great god, and anything can be at his fingertips, although Liangchen doesn't know if Lao Jun took it out of the Qiankun bag or conjured it out of thin air.

Liangchen first explained the principle to Taishang Laojun, "Lime will react violently when it encounters water, you should know this, and the reaction will generate carbon dioxide, when the reaction is a while, can you use a spell to introduce gas into this cup?"

"I know that lime reacts when it encounters water, and I also know that it generates gas, because water bubbles, but is there any difference in the gas generated?" asked Lao Jun, casting a spell while channeling the gas very simply.

"But you put this cup like this, won't carbon dioxide come out of it?" Lao Jun said strangely, Liangchen directly put a transparent cup very casually, there was no lid on it, and it was not sealed with a spell.

Ha, you don't understand this, sometimes you don't have to use spells for everything. Liangchen smiled and asked him to do the same.

Liangchen put the lime down in the water, the lime reacted violently and bubbled, and then in the conduit made of spells, the gas was introduced into the cup, and Liangchen also asked Lao Jun to extend this conduit to the bottom of the cup, whether it could collect carbon dioxide, which was a very critical step.

Liangchen didn't know if the carbon dioxide in the cup was full, so he guessed the time for a while, and then brought another cup, both of which were open upwards, and didn't seal the cup with anything.

"Well, now is the time to witness the miracle. Liangchen pretended to be mysterious, but in fact, he didn't have a bottom, after all, this method of collecting carbon dioxide was too rough, and there was still a lot of magazine gas.

But it doesn't matter, as long as carbon dioxide takes up the majority, it's enough.

"Liangchen, how do you know that the gas in this cup is carbon dioxide?" Lao Jun was puzzled, shouldn't the two cups be the same?
