The huge pressure rushed towards Xu Chuan, and he was not afraid, and even had a leisurely stroll.

Boom!

The water pressure was squeezing on Xu Chuan's body, and it couldn't cause him any harm.

He walked out of the passage step by step and came to the outside of the submarine, and at this time the passage of the submarine had long been tightly closed.

Xu Chuan smiled at Yue Ying through the glass of the submarine, revealing a mocking expression.

Didn't you say that he would be crushed to death by water pressure, and now there is nothing at all!

Yue Ying was completely dumbfounded.

At this time, she had to admit that in the virtual world, Xu Chuan was a god!

Xu Chuan turned to leave, seemingly slowly but extremely fast into the distance, leaving Yue Ying with a majestic figure.

Her heart was beating uncontrollably, as if she had touched a string buried in the deepest depths, and her eyes were full of worship for Xu Chuan.

But in the end, that feeling disappeared.

Xu Chuan left Minister Yue and went straight to the seabed iron mine, which was deep in the cracks on the seabed, and a large amount of iron ore was exposed on the surface, which was definitely a rich mine.

"I don't know if I can bring it to the real world."

It has always been Xu Chuan's dream to bring valuable things in the virtual world to the real world.

For example, these iron ores, if they can be taken out at will, Xu Chuan will not be rich.

There's a whole world of resources here!

"Give it a try." Xu Chuan's mind moved, and he teleported out with a piece of iron ore, but only he was teleported to the real world, and the piece of iron ore was not teleported at all.

"It still doesn't work." Xu Chuan shook his head and came to the virtual world again.

"Master, the iron ore can't be teleported, so what about after purification?" Xiaohong suddenly appeared, she was still wearing a red dress, a pair of red shoes on her feet, and her shoulder-length head fluctuated with the sea, which looked very cute.

But her eyes were full of the cunning of a little girl all the time, and she looked like a disobedient child.

"Then let's try." Xu Chuan's mind moved, and he smelted this piece of iron ore into iron, and with another thought, the purity of this piece of iron was almost raised to the limit.

Then, he took the iron and teleported it again, but it still failed.

"Not at all." Xu Chuan returned to the underwater world with a helpless expression.

"Master, maybe ordinary iron can't be teleported, but high-grade iron can't be teleported?" Xiaohong said curiously.

This is a reminder to Xu Chuan.

An iron ore not only contains a large number of ordinary ores, but also contains a small number of high-quality ores, which are called refined iron and dark iron in ancient times, but few people mention this high-quality iron in modern times.

"Try it." Xu Chuan hurriedly unfolded his divine sense and began to search.

About half an hour later, he really found a high-quality iron ore, but Xu Chuan didn't know whether it was refined iron ore or dark iron ore, so he temporarily named it refined iron ore.

The weight of this piece of refined iron ore is at least ten times greater than that of ordinary ore of the same volume!

Xu Chuan hurriedly smelted this piece of refined iron ore into refined iron, and then continued to purify it, and finally planned to bring it to the real world, but it still failed.

"Don't be discouraged, keep looking for higher quality iron ore." Xiaohong cheered up.

"And higher quality iron ore?" Xu Chuan frowned a little and said, refined iron ore is already very rare, it may not be visible in the real world, I didn't expect it to be more powerful than this.

"Master, you are lonely, the universe is not as big as you can imagine." Xiaohong said with some disdain.

"Uh......" was despised by children, and Xu Chuan could only shake his head.

Subsequently, he followed Xiaohong's advice and began to work hard to find that higher grade iron ore.

Almost the entire iron mine was searched, and just when Xu Chuan was about to give up, a piece really appeared.

This piece of iron ore is special!

It is not solid, but liquid, but firmly condensed together and does not disperse.

In the hand, its weight is at least a hundred times heavier than ordinary ore of the same volume!

"This should be the Chromite?" Xu Chuan didn't dare to confirm its name, so let's call it that.

The virtual world can produce dark iron, but can the real world also produce it?

Unknown.

This kind of dark iron must be a special item, maybe you can take it out!

"Master, why don't you hurry up and refine?" Xiaohong looked impatient, and was also full of curiosity about this piece of dark iron.

Xu Chuan hurriedly began refining.

Although the dark iron ore is liquid, since it is a mine, it must be refined, and after refining, it is the dark iron.

"Purify me!" After the refining was completed, Xu Chuan began to purify again.

It was not easy to purify this kind of dark iron, even if Xu Chuan was the creator, it took more than an hour to succeed.

Ordinary ore and iron ore can be purified in just a moment.

At this time, the dark iron is still liquid, but it is more transparent, and it cannot be seen unless you look carefully.

If it weren't for the faint green light scattered in the dark iron, it would definitely be as transparent as water, and it wouldn't be visible in front of you.

"Let's hope it will work out this time."

Xu Chuan was full of expectations, he was not so rare as this piece of dark iron, but wanted to know more about the secrets of the virtual world.

"Teleport!"

Xu Chuan took this piece of dark iron and immediately teleported out.

This time it was a success, and Xuantie was successfully brought back to the real world!

"Success?"

Until this time, Xu Chuan looked incredible, he really succeeded, it was completely an epoch-making event!

Enough to go down in history!

Whether the virtual world is illusory or real is already a huge question mark.

"Congratulations to the owner for getting a treasure...... Belch...... It doesn't seem to be of much use. Xiaohong's brow furrowed.

"Who said it's useless, it can be turned into energy!"

Very few people know that the raw material of Kitahara's battery is not electricity at all, but iron!

The company can convert iron into an energy source through a complex process, and the performance of this energy source is very similar to that of electrical energy, which can not only power any electrical appliance, but also does not power people.

This is where the so-called energy battery comes in.

"Hee-hee, you can use it to make a spaceship battery." Xiaohong looked like an epiphany.

Syllable.

Xu Chuan knocked Xiaohong's forehead and said, "Smart." ”

At present, the energy batteries produced by Beiyuan Company are only primary and secondary energy batteries, and one

The grade battery can only supply small appliances such as mobile phones, and the grade battery can be supplied to the car.

The third stage can supply large equipment, and only the fourth level and above can supply spacecraft.

The characteristic of high-grade batteries is the high purity of energy.

A metal like dark iron can be directly manufactured into high-grade batteries with little to no purification!

Moreover, the energy they contain is huge, just this piece in Xu Chuan's hand can make a fourth-level battery, and a fourth-level battery can support the operation of a small spacecraft for a month!

It's also a rare good thing.

"Master, master, let's hurry up and see if there is anything like this." Xiaohong is looking forward to it, if she can dig a large amount of Xuantie, it will also be a lot of income. "Good!" Xu Chuan is also looking forward to it and re-entering the virtual world.
