Shi Yu had a mouthful of complaints he couldn't voice.

He had honestly and sincerely worshipped for half a month, constantly chanting "Revitalize the glory of the Iron-Eating Beast, it is our duty," but the ruins showed no reaction at all.

On the contrary, as soon as he slightly denied the evolution form of the Iron-Eating Beast, the "spirit" of the ruins couldn't sit still.

What was this all about?

It was not as easy to talk to as the stone statue in Pingcheng at all.

Perhaps the "spirits" born from different relics, ruins, and antiques also had different personalities?

If he had known this, he should have shouted "The Iron-Eating Beast has no evolution form, debate me!" on the first day he arrived here.

……

This time, the historical image Shi Yu saw was still very brief.

He saw a tribe full of flaming furnaces.

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

Like blacksmiths, they were forging armor with batches of rare metals that Shi Yu found familiar.

Dong! Dong! Dong!

The sound of hammering iron kept ringing in Shi Yu's ears.

Then, alloy armor was put on by a group of Iron-Eating Beasts.

After the Iron-Eating Beasts put on the armor, they seemed to be using hardening at the level of perfection, releasing hardening substances to wrap the armor, making the armor completely integrated with themselves.

There were many types of armor. Some Iron-Eating Beasts wore complete armor, some Iron-Eating Beasts only had alloy giant claws equipped on their arms, and some Iron-Eating Beasts even picked up shields. They had different images, but they all used hardening at the level of perfection to connect themselves and the armor into one.

During this process, as they fused with the armor, their aura seemed to be greatly enhanced, and their size continued to increase under a burst of light.

After a while, the scene showed hundreds of Iron-Eating Beasts wearing various armors. They were neatly arranged in formation, which was extremely shocking. This group of Iron-Eating Beasts was like a well-trained army, ready to go on an expedition.

At the end of the image, the Iron-Eating Beasts used hardened claws to begin engraving special symbols on the armor. At this moment, their whole bodies flashed again...

The picture ended abruptly.

……

In reality.

Eleven poked its head to look at the silent Shi Yu, not understanding what had happened.

At this time, Shi Yu's mood was very subtle.

He didn't know what language to use to express his current mood.

No wonder Eleven Bureau absorbed him into the organization without saying a word when they encountered a Beast Tamer with the talent to listen to the sounds of history like him.

This ability was indeed a bit of a bug.

While other archaeologists were still exploring the mysteries of ancient times, archaeologists with this talent directly peeked into history like watching a movie. Wasn't this cheating?

"So, those metals aren't for eating." Shi Yu fell into deep thought.

They were actually forged into alloy armor and equipped on the Iron-Eating Beasts, and then connected with hardening at the level of perfection.

Don't tell him that this was the evolution method of the Iron-Eating Beast.

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

From the appearance, it felt like those metals detected by the metal piece.

If this was the case, then the evolution method of the Iron-Eating Beast was simpler than Shi Yu had imagined.

However, whether modern forging technology could turn those metal minerals into alloy armor like in ancient times was still unknown.

Then, what should this evolution method be called?

Item-equipped evolution?

There were also cases of equipped evolution among existing pets.

The evolution methods of artificial mechanical life were mostly equipped evolution.

However, there was still a slight difference between the two.

"Wait, that's not the point!"

Having only seen the evolution method of the Iron-Eating Beast, Shi Yu always felt that he hadn't glimpsed the full picture of history.

What were these Iron-Eating Beasts wearing armor and completing evolution going to do? War?

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

Why were there such symbols on Earth as well?

In the end, Shi Yu felt that he knew something, but not completely...

Forget it... let's start by studying the evolution form of the Iron-Eating Beast first.

……

"What happened?"

As Shi Yu listened to the sounds of history, this stone wall seemed to have exhausted its "life" and developed many cracks.

The "boom" tremor just now also directly attracted Panda Senior and the Seven Heroes of Archaeology.

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

Ahhhhhh!!!!

Everyone: w(ﾟДﾟ)w???

So, what happened!!!

"Ying."

Before Shi Yu could turn around, Eleven on Shi Yu's shoulder turned around first, revealing an innocent expression.

If it said that they just dissed the stone wall a few times and the stone wall exploded, would you believe it???

"Damn, what's going on."

The stone wall exploded, and Zheng Yingjie and the others' mentality also exploded.

Although the Iron-Eating Beast ruins were not very important before, it was their basic responsibility to keep such antiques intact, but now... something big had happened.

They looked at Shi Yu, who was slowly turning around. Could it be that Shi Yu hadn't been able to research anything for half a month and finally broke down and smashed the stone wall directly?

"Don't panic."

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

Stay calm.

"There are gains." Under the confused expressions of the crowd, Shi Yu smiled.

"I seem to know what the evolution method of the Iron-Eating Beast is."

"What?!"

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

Really?

"Well, let's go out and talk about it first," Shi Yu said.

Next, the crowd came to the open outside world.

They all looked at Shi Yu, their expressions full of anticipation and excitement.

So, what exactly did Shi Yu discover?

"The six metal components detected by that metal piece are indeed the key to the evolution of the Iron-Eating Beast."

"Before, we guessed the most that we should let the Iron-Eating Beast eat these metals. In fact, the real situation is similar."

"The evolution method of the Iron-Eating Beast should be to forge these six metal minerals into alloy armor, and then equip the Iron-Eating Beast with it. Finally, let the Iron-Eating Beast use the race skill Hardening at the level of perfection to perfectly wrap and fuse the power of the armor."

"The Iron-Eating Beast's hardening substance and this alloy should produce a special reaction to help them improve their life level."

The few people were obviously stunned.

Lin Xiuzhu said, "What's the principle?"

Shi Yu: "What do you want that for?"

"Then how did you determine it?"

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

Everyone was dumbfounded, feeling that Shi Yu hadn't said anything at all.

In the final analysis, it was still a guess. Based on their previous guesses, there was one more.

"Can those six metals really be forged into an alloy?" Zheng Yingjie asked blankly.

"We have been researching their properties and analyzing their properties these days, and there is no common ground at all."

Lin Yuer said, "So this method still requires hardening at the level of perfection..."

Everyone looked at Lin Xiuzhu.

Among the known Iron-Eating Beast Beast Tamers, there were really not many Iron-Eating Beasts that had mastered hardening at the level of perfection.

Lin Xiuzhu once said that her father, the curator Lin Hongnian, trained the Iron-Eating Beast for 21 years before training this skill to the level of perfection.

There was also Lin Xiuzhu. She started growing up with her Iron-Eating Beast when she was 10 years old.

Although she didn't contract at the time, she also started cultivating feelings with the Iron-Eating Beast from a young age and carried out preliminary training and running-in.

As a result, more than ten years later, her Iron-Eating Beast's hardening skill, based on her father's training experience, was only at the perfect level, and it was still far from the level of perfection.

If one of the evolution conditions of the Iron-Eating Beast was really hardening at full proficiency, then this condition seemed to be a bit difficult to achieve.

It was enough for the Green Silkworm's silk to reach the proficient level to meet the evolution mark, but the Iron-Eating Beast actually required a max-level race skill... It was simply a scam.

Moreover, the evolution materials of the Iron-Eating Beast were basically rare metals above level five. The price of making a set of armor with these metals was conceivable.

It could be said that even if the evolution method of the Iron-Eating Beast was made public, there seemed to be very few Beast Tamers who could meet this evolution condition.

Everyone had a stomachache. Was Shi Yu's reasoning reliable?

"Well, how about believing in my intuition?"

Shi Yu actually wanted to experiment too.

But unfortunately, he didn't have the evolution materials, and he didn't know how to turn these materials into alloys. There were technical difficulties.

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

Moreover, he hadn't made a decision on whether to let Eleven evolve. He would feel very strange if he had an iron lump standing on his shoulder in the future, and it would be heavy, and he would get shoulder problems sooner or later.

"Even if it's true, where do we go to try forging alloy armor, and where do we find an Iron-Eating Beast with hardening at the level of perfection to experiment..." Zheng Yingjie said with a headache.

Although there was a definite experimental route, it sounded like a big project with a research funding of hundreds of millions...

"It's okay, it's good to find a breakthrough."

Panda Senior thought for a while and looked at Shi Yu, saying, "I believe you. Do you want to study it? Our Zhushi Martial Arts Hall will bear the funding for the evolution materials. You can also use my father's Iron-Eating Beast as a guinea pig for the Iron-Eating Beast with hardening at the level of perfection."

Shi Yu: ...

Everyone called her a great filial daughter.

Panda Senior sold her father well.

"Mainly because it seems that only my father's Iron-Eating Beast meets the conditions. He has invested a lot of money in researching the evolution form of the Iron-Eating Beast. This time, it sounds more reliable than his previous random tinkering." Panda Senior shook her head.

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

Shi Yu was silent for a while and said, "Then I'll ask if Gu Du University can provide some technical help."

"The university should have more professional people in the forging of alloy armor."

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

Shi Yu contacted Gu Du University to seek technical help.

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

Whether the Iron-Eating Beast clan could soar into the sky and whether the price could increase depended on this wave.
