Chapter 671

Customers have turned their attention to Luochuan.

They already understood what was going on with that sound.

Luochuan's face did not change: "the special ability of the profession."

With a narrator, it's a special ability.

The crowd nodded suddenly, without much thought.

Luochuan shut down the BGM brought by the profession.

Look at the second heap.

The production of carbon dioxide can be realized by directly calcining stones at high temperature.

Calcium carbonate decomposes into calcium oxide and carbon dioxide at high temperature.

Calcium oxide reacts with water to form calcium hydroxide, which is used to test carbon dioxide.

The meaning of the previous chapter is roughly the same.

Well, yes, that's it.

Luochuan stressed.

He won't admit that the author's memory is wrong

This time, Luochuan controlled the power of the black flame.

Then, he started to burn the pile.

As time went by, the stone gradually turned red.

However, there seems to be a bit of an accident in the current situation.

The stone just turned red under the black paint fire.

From the beginning to the end, let alone carbon dioxide, there was no trace of other gases!

Is the temperature not enough?

Luochuan raised the temperature of the flame.

The color of the stone changes from bright red to blazing red.

A few minutes went by.

The original location of the pile, there is a hole.

There's magma flowing in it.

Luochuan thinks about the reasons for the current situation.

Calcium carbonate is found in most rocks in nature.

There's no reason why so many kinds of stones have been calcined at high temperature without even producing any gas.

The cause of the flame?

Or Why is the world today?

"And then, boss?" Bu Li Ge asked.

As Luochuan said just now, the second step is calcination.

According to the current situation, we should be able to proceed to the next step.

People have doubts looking at Luochuan.

Luochuan thought for a moment and said, "there's something wrong with doing experiments in the game. Change places. "

Then it disappeared.

People looked at each other, not quite understand the operation of Luochuan.

Luochuan has been offline, because of curiosity, they all quit the game.

Take off the helmet, Luochuan look to step away song.

"Stone? Don't worry, the boss. I'll be right back. " Step away from the song beat the chest should be under.

Step away from the original mall, the original more than a dozen students followed up.

Before long, many stones were piled up in front of the original mall.

"Boss, do you still want to burn it?" Asked Yueling.

Luochuan nodded.

"How about letting me come this time?" Yao Huichen said with a smile.

Luochuan looked at the drug dust, nodded: "yes."

As a pharmacist, the medicine dust can control the fire perfectly.

There was a red flame in his hand.

"Pay attention to the power of control, not too much." Luochuan added.

"I see." Medicine should return to dust.

Surrounded by many people, those Medicine Valley disciples look excited.

"This is the headmaster's red lotus fire, which is said to have come from ancient relics."

"It's said that the flame can even burn karma. I don't know if it's true."

"What a terrible flame..."

The crowd was amazed.

Chen Yingfeng, chuyang, these old venerable, face dignified.

As worshippers, they can clearly feel the power in the fire.

Although suppressed, there is energy deep enough to destroy heaven and earth.
