Chapter 670

However, it is good to have a lot of people, just to popularize the knowledge of chemistry to customers.

"Boss, what are you going to do?" Yao Ziyan also followed and asked curiously.

"There is a special gas in Sprite and Coke, you should all know it." Luo Chuan said.

The customers nodded.

"Boss, you are preparing..." Yao Huichen seemed to have guessed something.

Luo Chuan nodded: "Make that gas."

Everyone showed a "so it is" expression.

Luo Chuan began to think.

By the way, how is carbon dioxide produced?

Luo Chuan's memory is very good, otherwise it would be impossible to write a novel of Earth China.

Soon, Luo Chuan found the corresponding memory.

According to the current situation, the simplest way is the reaction between limestone and water.

As for some other chemical reactions, it's a bit of a hassle.

Well, it's because Luo Chuan is lazy...

"First of all, we need some stones." Luo Chuan said.

"Boss, I'll help you!" Bu Lige said excitedly.

"I'll go as well!"

A dozen people ran to the rocky beach not far away.

Not long after, a hill made of stones appeared in the clearing.

"The second step is calcination." Luo Chuan said.

Don't forget Luo Chuan's occupation in the casual mode - the Dark Flame Demon Lord, also known as the Dark Flame Envoy.

Luo Chuan stretched out his right arm to Shidui.

"I always feel that the boss is going to release some particularly powerful skills." Yueling's expression was excited.

"What a terrifying temperature, much more powerful than my fireball technique." Gu Yunxi sighed.

Everyone stared at Luo Chuan, for fear of missing something.

The temperature of Luo Chuan's palm rose rapidly.

The scene there is distorted visible to the naked eye.

Traces of black flames rose from his arms.

"Be devoured by the dark flames!"

A low voice sounded.

Luo Chuan's expression changed.

This is not what he said.

What's the matter with this narration of the second breath?

Hey, hey, the system, it must be yours! It must be!

When the narration sounded, flames emerged from Luo Chuan's hands.

Everyone's attention was also diverted from the narration.

The black flame that condensed into a dragon head charged towards the stone pile in front.

Immediately, an explosion occurred.

Smoke billows everywhere.

When the smoke and dust dissipated, a charred black pit with a diameter of several meters appeared on the spot.

The edge of the pit is in the shape of glass, which is the state of sand condensing after being melted at high temperature.

As for the pile of stones, it has long since disappeared.

Luo Chuan pondered.

This power seems to be a bit beyond his expectations.

The crowd was silent.

"Boss, is this calcination?" Bu Lige broke the silence.

Luo Chuan: "... A little mistake, I didn't control the power well. Go and get some rocks."

"Oh, I know the boss." Bu Lige responded.

More than a dozen people acted as coolies.

"Just now, I seem to have heard something." Liu Rumei said with a frown.

There was a hint of vigilance in Luo Chuan's eyes.

No, you don't.

. "Oh, I heard it too." The third elder nodded, then thought, "It seems to be something... swallowed up by the dark flames..."

Luo Chuan's gaze fell on the third elder.

Three elders, dangerous.

But he didn't seem to notice it himself.

"How do you say, you don't feel this way of speaking, it's very powerful. After listening to it, it makes people's blood boil." Chen Mo's expression was excited.

"That's right."

"right!"

Many young students expressed their approval.

You are all middle schoolers.

. Luo Chuan made a diagnosis for them.
