Nangong Invincible's pupils contracted, and he recalled his master's words: "Invincible, it's a pity, it's a pity that the alchemy furnace is too slow to raise temperature, so the teacher has not been able to practice the fourth-order pill!"

Seeing that Nangong Invincible didn't speak, Wu You thought that Nangong Invincible didn't agree with Qin Yu's words.

Wu You sneered: "The surname is Qin, don't be funny, the Liufang Ding is an artifact, and the heat transfer performance is very good! If the Liufang Ding is slow to raise temperature, then there is no alchemy furnace in this world that can raise temperature quickly!"

Qin Yu sighed lowly: "Brother Wu, say that you are frizzy, you are really frizzy! Now it seems that you are not only frizzy, but also have a bad memory! When did I say that it was the problem of the Liufang Ding? I clearly said just now that it was because of the earth fire!"

"The surname is Qin, you ......"

"Shut up!" Wu You was about to speak, but was rudely interrupted by Nangong Invincible! Wu You was so frightened that he didn't dare to say a word!

Nangong Invincible's eyes were shining, he looked at Qin Yu with excitement, and asked in a trembling voice: "Qin Xiaoyou, Mo Fei, do you know the way to speed up the temperature of the Liufang Ding?"

"Of course. Qin Yu smiled slightly.

"Really?Qin Xiaoyou, what can you do?" Nangong Invincible trembled with excitement and grabbed Qin Yu's arm!

Nangong's invincible performance made everyone stunned, what the hell? Qin Yu didn't talk nonsense? Su Ziyan's eyes were shining, her husband was amazing!

Wu You's mouth opened and he couldn't say a word, he felt that he couldn't understand the conversation between Nangong Invincible and Qin Yu.

Xiang Wentian asked in a deep voice, "Brother Nangong, why are you so excited?"

"Brother Xiang, do you know that a very important factor that restricts the alchemist is the purification of the medicinal materials! The faster the alchemy furnace is warmed, the more thorough the purification will be! If the temperature is raised too slowly, there will be some other changes when the medicinal materials are turned into liquids. ”

Xiang Wentian suddenly realized, turned his head to look at Qin Yu and asked, "Qin Yu, how can you speed up the temperature increase?

"It's very simple, you just need to purify the earthfire. Qin Yu smiled slightly.

"Purify the earth fire?" Nangong Invincible looked confused.

Wu You rolled his eyes, how could this surnamed Qin dare to say anything? How can the earth fire be purified? Isn't it funny?

"The surname is Qin, don't be grandstanding! Do you know what the earth fire is? How to purify the earth fire? You can really talk about it!"

Qin Yu said with a smile: "Of course I know what the earth fire is, the earth fire is composed of all kinds of biogas and all kinds of natural gas underground!"

"Now that you know what earth fire is, how do you purify it? It's just hilarious!"

Qin Yu said lightly: "The earth fire contains various alkanes such as methane and ethane, as well as various alkenes such as ethylene propylene, stupid and hydrogen sulfur gas.

Most of these gases are not cold to an inert substance, and when they encounter this inert substance, they will take a detour, and only benzene is very close to this substance. ”

Qin Yu's words made everyone look confused, only Su Ziyan's face showed an expression of sudden realization!

"Even if there is really such a substance, how can Qin Xiaoyou be sure that the temperature increase of the alchemy furnace can be accelerated? If the old man understands correctly, purifying the earth fire will make the gas passing through the earth fire pipe less!The temperature increase of the alchemy furnace should be slowed down!" Nangong Invincible looked at Qin Yu with a puzzled expression.

This time, there was no need for Qin Yu to speak, Su Ziyan said with a smile: "Nangong Valley Lord, it's like this, among all kinds of biogas and natural gas, only benzene and pentane have the highest combustion value, and the combustion value of both is around thirty-seven thousand.

The combustion value of other gases is generally less than 10,000, and the content of benzene occupies half of the total gas content in the fire, even if only half of the benzene is left, the heat generated is much higher than the original!

What's more, after purification, the content of benzene passing through the groundfire pipe will not be less than half of the total gas content, and the heat generated will definitely not be reduced. ”

Nangong Invincible opened his mouth and said with a sigh on his face: "I suddenly envy you young people! It's good to be educated!"

I remember a long time ago, there was a disciple who once discussed chemistry or something with the old man, but the old man didn't give him a good face at all!

If he had known about today, the old man should have had a good discussion with that disciple at that time. Perhaps, the old man has already made a breakthrough in alchemy. ”

"Master, it's not certain that the surname Qin is accurate, don't be presumptuous, what has been handed down by the ancestors for thousands of years must be reasonable, how can it be so easy to be denied?"

"If it is so easy to be exposed, why would Qin Yu say such a thing? Isn't this lifting a stone to shoot himself in the foot? Wu You, can you be humble?"

Reprimanded Wu You angrily, Nangong Invincible sighed faintly, no longer bothered with his apprentice, turned his head to look at Qin Yu and said, "Qin Xiaoyou, please." ”

Wu You's face turned blue and white for a while when he was reprimanded, and he could only look at Qin Yu coldly, hoping that Qin Yu would fail!

Unfortunately, Wu You's hopes were destined to be disappointed, and Qin Yu summoned a black stone from the Ziwei Star Ring, and at the same time summoned the Xuanyuan Divine Sword.

Qin Yu carved this black stone with the Xuanyuan Divine Sword, carved it into the shape of a T-shaped tube, and soon, Qin Yu finished carving.

Under the gaze of everyone, Qin Yu put the T-shaped pipe into the earth fire pipe, and then clapped his hands and said, "Okay! ”

Everybody was stunned, that's fine? Just put such a black thing?

Although he was a little confused, Xiang Wentian still followed what Qin Yu said, and opened the Earth Fire Valve! As soon as he opened the Earth Fire Valve, everyone was dumbfounded!

Poof! Poof! A wave of heat is coming! The temperature is more than n higher than just now! Everyone hurriedly took two steps back!

Nangong Invincible stared at it, the flames at the bottom of the alchemy furnace were obviously not as strong as just now!

Wu You's mouth is so big that he can almost swallow a goose egg! Nima's, what the hell? 500 degrees, 600 degrees, 700 degrees? This is too perverted, isn't it? It's only a few seconds?

"I'm convinced! It would take at least a quarter of an hour for the old man to raise the Liufang Ding to a thousand degrees before! But now, it doesn't even take ten breaths, right? If my master is still alive! If he can have such a high temperature raising efficiency! Maybe he can be successfully promoted to a god-level alchemist!"

Speaking of this, tears flowed from Nangong's invincible eyes! Master, it's a pity for your old man!

At the same time, there was still a trace of happiness in Nangong Invincible's tears! Thanks to him for coming here! Otherwise, he would not know how to improve the efficiency of temperature raising for the rest of his life!

Knowing this method, his Nangong Invincible is no longer far away from a god-level alchemist!
