Shi Yu had a lot of complaints in his heart but could

n't vent them. He had been worshipping honestly and sincerely for half a month, and he kept repeating in his heart, "It is our duty to recast the glory of the Iron-eating Beast", but the site didn't react at all .

On the contrary, after slightly denying the Iron-eating Beast's evolution, the "spirit" of the site immediately couldn't sit still.

What's this?

It's not as easy to talk to as the stone statue in Pingcheng.

Perhaps, the "spirits" born from different relics, ruins, and ancient objects also have different personalities?

If he had known this, he should have shouted "The Iron-eating Beast has no evolution at all, come and argue if you don't agree" on the first day he came here.

...

This time, the historical images that Shi Yu saw were still very brief.

He saw a tribe full of flaming furnaces.

In the tribe, there was a group of strong men with bare chests.

They were like blacksmiths, using batches of rare metals that Shi Yu found familiar to them to forge armor.

Dong! Dong! Dong!

The sound of iron hammering kept coming into Shi Yu's ears.

Then, a group of iron-eating beasts put on the alloy armor.

After the iron-eating beasts put on the armor, they seemed to use superb hardening to wrap the armor with external hardening materials, making the armor and themselves completely integrated.

There are many types of armor. Some iron-eating beasts wear complete armor, some iron-eating beasts are just equipped with alloy claws on both arms, and some iron-eating beasts even hold shields. They have different images, but they all use superb hardening to connect themselves and the armor into one.

During this process, as the armor was fused, their momentum seemed to be dramatically enhanced, and their size continued to grow under a burst of light.

A moment later, hundreds of iron-eating beasts wearing various armors appeared on the screen. They were neatly arranged in formation, which was extremely shocking. This group of iron-eating beasts was like a well-trained army preparing to go to war.

At the end of the video, the iron-eating beasts used their hardened claws to start engraving special symbols on the armor. At this moment, their whole bodies flashed with light again...

The picture stopped abruptly.

...

In reality.

Eleven probes looked at the silent Shi Yu, not understanding what happened.

At this time, Shi Yu was in a very subtle mood.

He didn't know what language to use to express his feelings at the moment.

No wonder the 11th Bureau absorbed him into the organization without saying a word when they encountered a beast tamer like him who had the talent to listen to the voice of history.

This ability is indeed a bit buggy.

While other archaeologists were still exploring the mysteries of the ancient times, archaeologists with this talent directly explored history like watching a movie. This is not cheating.

"So those metals are not used for eating." Shi Yu fell into deep thought.

It turned out that they were made into alloy armor and then armed with the iron-eating beast, and then connected with superb hardening.

Don't tell him that this is how the iron-eating beast evolves.

In the picture, Shi Yu also saw the materials for forging the alloy armor.

From the appearance, it feels like the metals detected by the metal sheet.

If this is the case, then the way the iron-eating beasts evolved is simpler than Shi Yu had imagined.

However, it is still unknown whether modern forging and processing technology can turn those metal minerals into alloy armor like in ancient times. So

, what should this way of evolution be called?

Tool-based evolution?

As for armed evolution, it is not uncommon for existing pets.

The evolution method of artificial mechanical life is mostly armed evolution.

However, there is still a small difference between the two.

"Wait a minute, this is not the point!"

Shi Yu only saw the way the iron-eating beasts evolved, and he always felt that he did not get a glimpse of the full picture of history.

What are these iron-eating beasts going to do after wearing armor and completing their evolution? War?

What do the different symbols they engraved on their bodies in the end mean?

Why is there such a symbol on Earth?

In the end, Shi Yu felt that he knew something, but he didn't know it completely...

Never mind... Let's start with the study of the evolved form of the Iron-eating Beast.

...

"What happened."

As Shi Yu listened to the voice of history, the stone wall seemed to have exhausted its "life" and many cracks appeared. The trembling sound of   "boom" just now   also

directly attracted Panda Senior and the Seven Heroes of Archaeology.

After they came over, they immediately saw the stone wall full of cracks and Shi Yu with   his back to them.

Ah ah

...   If it said that they just said a few words to the stone wall and the stone wall exploded, would you believe it? ? ?   "Shit, what happened."   The stone wall exploded, and Zheng Yingjie and others were also shocked.   Although the iron-eating beast ruins were not very important before, it was their basic responsibility to keep such ancient relics intact, but now... something big has happened.   They looked at Shi Yu who turned around slowly. Could it be that Shi Yu couldn't figure out anything after half a month, and finally lost his mind and smashed the stone wall directly?

"Don't panic."

At this time, Shi Yu turned his head and looked at the panicked crowd, and comforted them.

Stay calm.

"There is a gain." Shi Yu laughed at the confused expressions of the crowd.

"I seem to know how the iron-eating beast evolved."

"What?!!"

Hearing Shi Yu's words, everyone was more shocked than seeing the cracks in the stone wall. They all widened their eyes and looked at Shi Yu.

Is it true or false?

"Well, let's go out first." Shi Yu said.

Next, everyone came to the empty outside world.

They all looked at Shi Yu, their expressions were very expectant and excited.

So, what did Shi Yu discover?

"The six metal components detected in that metal piece are indeed the key to the evolution of the Iron-Vein."

"Our most common guess before was to let the Iron-Vein eat these metals, and in fact the real situation is similar." "

The way for the Iron-Vein to evolve is to make these six metal minerals into alloy armor, then equip the Iron-Vein, and finally, let the Iron-Vein use its superb racial skills to harden it, perfectly wrapping and integrating the power of the armor."

"The Iron-Vein's hardened material and this alloy should produce a special reaction, helping them to improve their life level."

Several people were obviously stunned.

Lin Xiuzhu said, "What about the principle?"

Shi Yu: "Why do we need that thing?"

"Then how did you know for sure?"

"Uh..." Shi Yu was stunned, and said, "Intuition?"

Everyone was dumbfounded, as if Shi Yu had said nothing.

To put it bluntly, it was still a guess, and they had one more guess based on their previous guesses.

"Can those six metals really be made into alloys?" Zheng Yingjie was at a loss.

"We have been looking up data and analyzing their properties these days, and there is absolutely nothing in common."

Lin Yuer said, "So this method still requires superb hardening..."

Everyone looked at Lin Xiuzhu.

Among the known iron beast tamers, there are not many iron beasts that have mastered superb hardening.

Lin Xiuzhu said that her father, the owner of the Lin Hongnian Gym, trained the Iron-eating Beast for 21 years before training this skill to the superb level.

And Lin Xiuzhu, when she was 10 years old, she began to grow up with her Iron-eating Beast.

Although there was no contract at that time, she also began to cultivate feelings with the Iron-eating Beast since childhood, and then carried out preliminary training and running-in.

As a result, today, more than ten years later, her Iron-eating Beast's hardening skill, based on her father's training experience, is only at the perfect level, far from the superb level of proficiency.

If one of the conditions for the evolution of the Iron-eating Beast is really a hardening with a sufficient level of proficiency, then this condition seems to be a bit difficult to achieve.

When the silk of the green cottonworm reaches the skilled level, it is enough to mark the evolution, but the iron beast requires the full-level racial skills... It's simply a rip-off.

Moreover, the evolution materials of the iron beast are basically rare metals above level 5. The price of using these metals to build a set of armor can be imagined.

It can be said that even if the evolution method of the iron beast is made public, there seem to be very few beastmasters who can meet this evolution condition.

Everyone had a stomachache. Is Shi Yu

's inference reliable? "Well, why not trust my intuition?"

Shi Yu actually wanted to experiment.

But unfortunately, he has no evolution materials, and he doesn't know how to make these materials into alloys. There are technical difficulties.

In addition, Eleven's skill proficiency is not up to standard.

Besides, he has not yet decided whether to let Eleven evolve. He will feel strange with a piece of iron on his shoulder in the future. It is also heavy, and he will get shoulder disease sooner or later.

"Even if it is true, where can we try to forge alloy armor, where can we find a skilled Iron-eating Beast to experiment..." Zheng Yingjie said with a headache.

Although there is a definite experimental route, it sounds like a large project with a research budget of hundreds of millions...

"It doesn't matter. It's a good thing to find a breakthrough."

Senior Panda thought for a moment, looked at Shi Yu and said, "I believe you. Do you want to do some research? Our Zhushi Martial Arts School will bear the cost of the evolutionary materials. For a master-level proficiency Iron-eating Beast, you can also use my father's Iron-eating Beast as a guinea pig."

Shi Yu: ...

Everyone called her a filial daughter.

Senior Panda sold her father well.

"The main reason is that it seems that only my father's Iron-eating Beast meets the requirements. In order to study the evolution of Iron-eating Beast, he invested a lot of money. This time it sounds more reliable than his previous mess." Senior Panda shook her head.

"If he knew, he would definitely be willing, and even take the initiative to ask to come over to cooperate."

Shi Yu was silent for a moment and said, "Then I will ask if the Ancient Capital University can provide some technical assistance."

"As for the forging of alloy armor, there should be more professional people here at the university."

Shi Yu and Senior Panda looked at each other, nodded to each other, and hit it off.

Shi Yu contacted Ancient Capital University for technical assistance.

Senior Panda contacted her father to be a guinea pig for the experiment.

Whether the iron-eating beasts can soar to the sky and whether they can increase their prices depends on this wave.
