Shall we go to open up the wasteland together tomorrow?

In order to study this unknown gas.

The four of them came to the Lone Tower Laboratory together.

"Clark, you should be able to control these gases."

Clark nodded, then took out a magic wand from his arms and waited for it.

"Let me ask you a few questions first."

"Can you feel the existence of this gas?"

Clark nodded.

"... It exists around, but it feels very weak, and the amount is too small, so it cannot be controlled."

Ethan nodded.

It's easy to feel it, it must be a substance in the air.

"Since it can't be controlled, where did you get this small bottle of substance..."

Ethan pointed to the crystal bottle in front of him.

Clark told the story.

"My hometown is located in a small village in Titan City in the north of the Federation, where there is a huge abandoned mining area.

Once I accidentally fell into a cave, and when I came out, I had awakened to the extraordinary."

It seems that Clark also had an adventure. It is likely that he was able to awaken because he passed the baptism in the abandoned mining area.

"And this small bottle of material was also collected from there."

"Abandoned mining area..."

Ethan repeatedly confirmed his guess.

"What kind of mine was the mining area originally?"

"Coal mine. The steam train from Behemoth City to Zion City would transport a lot of coal when passing through there. My ancestors for three generations were miners."

"But more than a decade ago, for some unknown reason, a large amount of black water suddenly emerged from the bottom of the coal mine, and one section of the mine suddenly collapsed, leaving many miners inside, so it was abandoned later."

"I see."

Ethan nodded.

The black water that Clark mentioned is most likely the oil that the miners dug deep underground.

Generally speaking, the gas that exists with oil is most likely natural gas.

But according to the volume of natural gas, it is impossible to have only a little in this small bottle.

Ethan suspected that the gas that Clark could control had to be found in the appendages of natural gas.

In short, as long as it exists in the air, Ethan will definitely be able to find a way to separate it.

It's just that the air content in this world should be different from that in the previous life.

Ethan still couldn't be sure of the composition of the gas.

Colorless, odorless, and tasteless can exclude many types, such as alkanes, alcohols, ammonia, sulfides, etc.

But there are still many other gases that meet the requirements, such as natural gas, oxygen, carbon dioxide, hydrogen, nitrogen, etc.

Ethan flipped his left palm, and the residual lamp appeared in his hand.

First, the flammability of this gas must be tested. Since it was found in the mining area, it should have the ability to burn to a large extent.

Ethan signaled Clark to control a trace of gas to appear above the flame.

But when the dark yellow flame came into contact with the gas, the gas not only did not burn, but its shape kept changing. As Clark moved it, the flame in front of him began to jump.

Not flammable?

Ethan increased the output of telekinesis, but still could not affect this gas.

Instead, the flame was confused by this gas.

Cannot burn, nor can it help combustion...

Then hydrogen, oxygen, carbon monoxide, etc. can be excluded.

Ethan found some lime powder, dissolved it in water, and asked Clark to introduce the gas in the small bottle into the water.

The clear lime water did not become turbid.

Then carbon dioxide was excluded.

But the remaining... nitrogen?

Ethan was in trouble for a moment.

Nitrogen is a very stable gas, and it is generally difficult to change its properties.

Ethan shook his head, which should not be right.

Because the content of nitrogen in the air is also very high.

And if it is nitrogen, it should have reacted chemically with the oxygen in the air under Ethan's ultra-high temperature burning.

But now these gases still have no reaction.

The most important thing is that if these gases are really nitrogen, Clark cannot collect only such a small bottle.

Because the proportion of nitrogen in the air is very large, even in the high concentration of natural gas in nature, the content of nitrogen can account for about 2%.

Ethan turned off the remaining lights, and then signaled Clark to collect these gases into the crystal bottle.

He sat in front of the experimental table and pondered.

Colorless, odorless, insoluble in water, extremely inactive, still unable to undergo redox reactions under ultra-high temperature combustion.

At this time, the name of a class of substances flashed through his mind: inert gas.

Helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn, radioactive), (gas Og, radioactive, artificial element).

The last one is an artificial element, which is very easy to decay and is unlikely to appear in this world.

Radon is also radioactive and widely present in natural stone. It will decay into alpha particles only after being inhaled by humans, which is the key factor causing lung cancer.

This substance exists in many decoration materials in the previous life. Ethan has been in contact with such patients so he has some understanding.

But this substance is also rare in natural gas.

Among the remaining helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe), Ethan thinks the biggest possibility is helium!

"Clark, when you don't control this gas, does it float up or sink down?"

"Float up, and run very fast~"

After getting Clark's answer, Ethan's eyes lit up, it was indeed helium.

First of all, helium is one of the rare gases commonly found in natural gas. Secondly, helium has a small atomic sequence and is very light, second only to hydrogen. It always floats in the top layer of air or natural gas.

It is not an exaggeration to say that it leaked from cracks in the mining area.

Moreover, it is colorless, odorless, tasteless, and not easy to burn. It is the only substance that cannot solidify under standard atmospheric pressure.

This series of conditions all meet the characteristics of helium.

And helium was widely used in the previous life.

First of all, the inactive nature of helium is very suitable for use as a protective gas, and it is easy to use it to make syringes.

Secondly, liquid helium will vaporize rapidly at room temperature and pressure, absorbing a large amount of heat, and is often used in ultra-low temperature cooling technology.

Finally, during the vaporization process, the volume of helium increases instantly, so it will generate strong air pressure, and coupled with its own inactive nature, it is often used as a booster gas for rockets.

Similar to the principle of liquid nitrogen acceleration, liquid helium acceleration is even more brutal.

But Ethan values ​​the light weight of helium the most. In the previous life, the streets were full of helium-filled balloons, and there were helium aircraft researched by many countries.

In other words, mastering helium seems to be able to master airship technology! Strong pressure boost technology!

These two technologies can be fully applied to the hull of the ‘Dawn of the World’, which can fly and run!

In one word... Absolute.

Thinking of this, Ethan's eyes changed when he looked at Clark.

It seems a bit of a waste of talent for this guy to just help himself make syringes.
