In the alchemy room, the heat is blowing on the face, and the surging heat wave makes people feel like walking into a furnace.

If ordinary people come here, they won't last a few minutes. Even if you are a martial artist, you can't stay here for a long time, only a grandmaster can stay for a long time.

Alchemy is indeed not an easy task. Many people can't stand this environment alone.

However, Ye Jun was quite satisfied.

Because, this alchemy room is completely made of fire ore, isolated from the outside world, and the temperature of the hot gas inside has reached a balance, which is very stable.

The root of all this comes from underground lava.

In front of Ye Jun, an alchemy furnace was completely made of Huoyuan stone.

Underneath the alchemy furnace is a well. The well was not flowing with water, but with lava.

It is this living lava that ensures the stability of the environment.

Even in the realm of cultivating immortals, not every sect has such a good alchemy environment. The vast majority of them use formations to maintain the environment of the alchemy room.

There is this stable lava earth fire here, which is enough to increase the probability of alchemy success by one percent, and if you lay out a suitable formation, it is not impossible to increase it by two percent!

Don't underestimate this probability of two percent, it can often play a key role.

Moreover, if a large amount of alchemy is alchemized for a long time, this probability of two percent can also greatly save the cost of alchemy.

"I originally planned to collect the Fire Element Stone and build an alchemy furnace, but I never thought that all the Fire Ore and Fire Element Stone collected by the Worm Valley would be used here. It saved me a lot of trouble! Ye Jun bowed slightly, quite satisfied: "With this alchemy room, it will be convenient for me to refine the pill in the future." ”

Although it is said that Ye Jun can use an ordinary alchemy furnace or even a large iron pot to refine the Spiritual Qi Pill.

However, the elixir that is really in the grade is different.

Still need to find a suitable place and take it seriously.

Otherwise, even if it can be successful, it will be much less efficient. The medicinal materials that could have produced ten pills may only have three or five pills in one furnace.

If it was here, Ye Jun would be sure that he would not only be 100% successful and not waste any materials, but also be able to refine a high-quality elixir.

Even if Ye Jun returns to Gusu and wants to refine the pill in the future, he can come here. Although it is thousands of miles away, with the current means of transportation, it can be reached in one day.

Next, it's alchemy.

Ye Jun was not in a hurry.

Instead, he walked up in the alchemy room, and from time to time, carved symbols on the ground and walls.

After a few minutes, the walls were almost filled with various runes.

Ye Jun stomped his foot violently!

Just listening to the sound of "hum", the entire alchemy room shook slightly.

Immediately, a ray of light appeared.

One by one, the symbols lit up, like resurrected tadpoles, connected head to tail, and finally, formed a huge formation with the runes on the ground.

Suddenly, all the hot air in the entire alchemy room was absorbed by the formation, and it converged towards the alchemy furnace in the middle.

Airplanes!

The alchemy furnace suddenly seemed to be on fire, and the whole body was red.

And in the alchemy room, in an instant, it became much cooler.

This is because, originally, the air was filled with the fire qi that escaped from the lava, but now, these fire qi have been sucked away by the formation, and although the air is still a little hot, it is no longer so terrifying. Even ordinary people can accept it, at most they just feel a little hot.

That's where the formation comes in.

Before, although the temperature of the alchemy room was balanced and the heat was full, after all, it was still not stable enough after all. If there are people coming in and out, the air from the outside world will definitely be affected. This is also the reason why the Presbyterian Council does not like outsiders to come here. Even before Ye Jun opened the alchemist, Elder Chang almost turned his face in anger, which couldn't be blamed on him.

Now, there's no need to worry about that. All the hot gas was controlled by the formation, and all of it was maintained on the alchemy furnace, which was completely stabilized. It does not affect the outside world and is not affected by the surrounding air.

Immediately, Ye Jun waved his hand, and the door of the alchemy room opened.

Outside, all the elders listened to the movement from inside, their faces were different, especially Elder Chang was even more worried, although they knew that Ye Jun knew how to make alchemy, but they were still afraid that Ye Jun was too young and reckless, and there would be problems inside.

At this time, everyone heard Ye Jun's voice from inside, and immediately, they saw the door open.

"You can come in!"

Elder Chang couldn't hold back any longer, and was the first to rush in.

As soon as he entered, Elder Chang's complexion changed.

Sure enough, something went wrong.

There was no heat in it.

Can this still be called an alchemy room?

The other elders also walked in at this time, and they all looked around curiously.

Few of these elders have actually entered here. In the past, Elder Chang was like a treasure, not being seen by people, even if he begged him to refine the pill, he could only wait outside.

"Nothing unusual, isn't it? And I used so much fire ore, it's no different from the outside! Someone said.

"It was different, but now, it's all ruined by him!" Elder Chang wanted to cry without tears.

The other elders were surprised, Ye Jun had been busy for so long, just to cause sabotage?

"Take a good look at it!" Ye Jun was expressionless and said lightly.

Elder Chang looked at it carefully. There was no heat, but there were a lot of runes on the walls.

"This is a formation?"

"This is Danwen?"

Elder Chang wiped his eyes. Somewhat incredulous, he looked closely along the wall.

In the end, his gaze fell on the alchemy furnace, looking at the alchemy furnace that was transparent red all over, Elder Chang was a little incredulous, and said, "Could it be that you used the formation to gather all the heat sources on the alchemy furnace?" ”

"It seems that you are not stupid either!" Ye Jun's expression was indifferent, as if he had done something worthless.

But seeing Elder Chang jump up suddenly, his expression must be excited, and said, "Can you still do this?" How can this be? But how to control the temperature of the alchemy furnace? Alchemy is not completely high! ”

"It's not easy!" Ye Jun stomped his feet.

The surrounding formations began to operate, and the red color on the alchemy furnace began to slowly fade.

Then, Ye Jun played another trick.

Airplanes!

Under the alchemy furnace, in the lava, a fire erupted.

The size of the flame, the temperature and the temperature, are completely controlled by the formation.

"Can it still be like this?"

"Wonderful! Wonderful! ”

Elder Chang first fell into a stupor, and then he was ecstatic, shouting: "With this formation, I can easily control the temperature, control the heat at will, and the success rate of alchemy can be increased by at least two percent!" And there's no longer any need to look at the fire. ”

You must know that in the past, he almost didn't dare to leave half a step for the sake of alchemy. Because the fire is unstable, if you are not careful, the fire may burn the medicinal herbs when it is big, and the power is not enough if the fire is small. Sometimes, you have to add charcoal to control!

Now that there is a formation, it is simply a manual home appliance replaced by a smart home.

Although the other elders couldn't see how this formation could help alchemy, such a complex and perfect formation was actually laid out in just a few minutes, which was enough to shock them.
