Ancient Capital University, student dormitory.

At noon, Shi Yu returned to the campus.

After returning, Shi Yu took an ice shower, ate a popsicle, and lay down on the bed with satisfaction.

"Hmm."

Eleven also held a bowl of milk-flavored ice cream and ate it with relish.

This is an ice cream made from the breast milk of a female iron-eating beast. It is produced by Senior Panda Sister's family. The iron-eating beast said it was good after eating it.

"Aiya~burp~"

As for Shen Baobao, he gulped down the ice soda.

If the food that Eleven eats is still nutritious, then what it drinks is pure garbage happy water.

But in the words of Shen Baobao, it itself is already very nutritious, and the water source and so on, just drink it for fun.

Along the way, Shi Yu and his friends were all influenced by Little Red Eyes and were eager for something cool.

Unfortunately, the bug has no mouth, so it can only continue to paint the world's famous paintings. The bug is sleeping.

"Meow~"

After arriving in the new environment, Little Red Eyes undoubtedly went into the refrigerator again, holding its ice energy crystal .

Shi Yu didn't care whether the refrigerator was in danger of being burned. He yawned and looked at the courses that would be held after school officially started the day after tomorrow.

But as he was looking at it, a video call box suddenly popped up on his phone.

"Huh."

Shi Yu glanced at the ID, and after finding out that it was Senior Panda, he swiped to answer it directly.

A moment later, Lin Xiuzhu's face appeared on the screen.

Her face was very close, her expression looked very excited, and her eyes revealed joy.

"Big, big, big super big discovery!"

Lin Xiuzhu said directly, "There are two good news, which one do you want to hear?"

Shi Yu blinked.

"Listen to the second best one first."

Lin Xiuzhu smiled and said, "I have researched a method to let the Iron-eating Beast awaken the "Giant" skill steadily before evolution."

"Really??" Shi Yu was surprised.

"Well, the resources used are more expensive, but compared to the evolution materials, it's not bad."

After determining that the amount of evolution materials determines the potential of the Iron-eating Beast after evolution, Lin Xiuzhu has been researching a method to let the Iron-eating Beast awaken the gigantic skill before evolution.

If it can be researched, it will be a very important improvement for the potential of the Iron-eating Beast clan.

This means that as long as there is money, every Iron-eating Beast has a chance to reach the high-level king race.

"Amazing, awesome." Shi Yu praised.

Master Lin Hongnian has developed a skill secret book that allows Iron-eating Beast to learn Thunder Palm and Cannon Fist.

Now Lin Xiuzhu has developed a skill secret book for Iron-eating Beast to awaken and become giant.

This father and daughter are really talented in their research on Iron-eating Beast.

The price of Iron-eating Beast has increased by +1, so he just needs to wait and collect the money.

"Wait, is there better news than this?" Shi Yu discovered the blind spot.

"Hehe." Lin Xiuzhu looked proud and said, "I have also found a way to quickly improve the 'hardening' proficiency of the Iron-eating Beast."

"In the breeding base, a young Iron-eating Beast used this method, and in just one week, its hardening level reached the mastery level."

If Shi Yu was just slightly surprised when Senior Panda said that she had developed a method of awakening to gigantism, then now, he was very surprised.

"How did you do it?" Shi Yu was stunned. Senior Panda was too strong.

The four years of studying in the breeding and research departments were not in vain.

If a method is really found to quickly improve the proficiency of hardening, then Iron-eating Beasts can be evolved in batches.

By then, the status of Iron-eating Beasts will rise again!

Shi Yu originally planned to do some research on his own when he had time, but firstly, he didn't have time for the time being, and secondly, he had more important tasks at the moment, such as exploring the second stage of the evolution of the Iron-eating Beast.

However, in the blink of an eye, Senior Panda has figured it out?

"Do you remember that the research paper on the evolution of the Iron-eating Beast mentioned that the hardened material of the Jiuli War Beast has a slightly different internal structure than the hardened material of the Iron-eating Beast?"

Shi Yu nodded.

"This is the key point."

"The hardening of the Jiuli War Beast has a 'nourishing' effect on the hardening of ordinary Iron-eating Beast."

"With the characteristics of the superb hardening, such as the release, flow, and application, the Jiuli War Beast can use its own hardening material to nourish the small Iron-eating Beast."

"Under nourishment, as long as the hardening energy flows through the body of the small Iron-eating Beast, the amount of hardening of the small Iron-eating Beast and the ability to control the hardening can be rapidly improved."

"I have already experimented with my father's Jiuli War Beast. Its hardening can even promote and strengthen the perfect hardening of my Iron-eating Beast."

"That is to say, as long as one Jiuli warbeast devotes all its energy to continuously strengthening and hardening another Ironbeast, then the hardening improvement speed of that Ironbeast will theoretically be very fast, and the upper limit of the improvement is very high, depending on the hardening level of the Jiuli warbeast!"

Shi Yu: "!!!"

"This is indeed a super big discovery..." He was stunned and said to the screen.

What's the difference between this and the power transmission and body tempering in martial arts novels!

Can hardening skills be played like this?

No wonder there are so many Ironbeasts mastering high-level hardening in the images on the stone wall.

As long as there is a big guy to lead the upgrade, a highly skilled Ironbeast army can indeed be cultivated with some time!

"Is there anything I can do?" Shi Yu asked.

"Doesn't the Iron-eating Beast Research Institute at the Ancient Capital University still raise three Iron-eating Beast cubs?"

"Zheng Yingjie and his team are taking care of them."

"Yes." Shi Yu nodded.

Lin Xiuzhu: "Can you take them to verify again and see if Eleven can help them improve their hardening level?"

"Sure." Shi Yu nodded. Even without Lin Xiuzhu's advice, he would try it.

The superb hardening can help Iron-eating Beasts strengthen the hardening material, so what about the full-level hardening of his own Eleven?

He felt that among the Iron-eating Beast Legion he saw, there must be at least one Jiuli War Beast that has mastered the full-level hardening.

"Please."

"Then I'll go now. If possible, senior sister, please come to the ancient capital again when you have time. I'll let Eleven help your little flower to improve its hardening proficiency." Shi Yu said. "

Okay." Lin Xiuzhu smiled.

...

"Eleven!!"

Eleven had just finished eating a bowl of milk ice cream and was about to do a 10,000-meter high altitude drop training when he was stopped by Shi Yu.

"Yeah!!" Eleven shook his head.

What's wrong.

"Don't train yet. Come with me to do an experiment to see if you have the potential to take care of a baby."

"Huh?" Eleven was at a loss.

It's only two years old, and it's a baby itself.

"Let's go, and I'll get you a student card by the way. When the time comes, you can go to the gravity room, charging room, competition tower and other training facilities by yourself."

"!!" Eleven's eyes lit up.

"

Ah

...

​

​

Next, Shi Yu started to head to the Iron-eating Beast Research Institute.

Because he was worried about leaving Akato at home alone, he also pulled the sleeping little sword spirit up from the pile of ice cream.

Hardening can lead to hardening...

Along the way, Shi Yu first felt magical, and then found it understandable.

Judging from various historical traces, the Iron-eating Beast should be a group-based military style of warfare.

They are closely connected to each other, as can be seen from the skill "Solid as a Rock".

Although Shi Yu has not had time to add points to "Solid as a Rock" to Eleven, Shi Yu has already understood the characteristics of this skill.

This gold skill is described as being protected by the power of gold, enhancing all-round resistance. Solid as a Rock has resistance to elemental, physical, mental, and soul damage.

This is undoubtedly a very powerful skill, but if that's all, wouldn't it be more appropriate to call it "Golden Guardian" than "Solid as a Rock"?

The reason why the ancients named this skill Solid as a Rock is simple, because after reaching the mastery level, it will become a resonance skill.

There is nothing special about a pet using Solid as a Rock, but if there is another pet next to it that also uses Solid as a Rock, then the Solid as a Rock skills of both parties will resonate. Although it cannot achieve the exaggerated effect of stacking the effects, it will strengthen each other.

Moreover, the resonance effect and the number of resonant skills will increase with the increase of skill proficiency.

Imagine if there is a pet army of hundreds, thousands, or even tens of thousands of beasts, all of which have mastered the Solid as a Rock skill. When they fight, the power of 10,000 Solid as a Rock strengthens each other, how terrifying would the effect be? Although this is only a high-level skill, its tactical value is not inferior to any super-level skill!

This is a skill that becomes more powerful the more people use it. It is a legion skill specially designed for war. With the combination of Inward Edge, Giantization, and Hardening, it can easily create an invincible army.

In ancient times, Solid as a Rock refers to a solid city wall or a well-defended moat. It is undoubtedly very appropriate to compare a pet army that has mastered this skill to this.

"It's a pity that I only plan to train one Iron-eating Beast, so the skill of Solid as a Rock is useless."

He can't train an army of Iron-eating Beasts just for a skill, just like he wants to start a war. Thinking about it, Shi Yu sighed.

This is a high-level skill for a single unit, a super-level skill for a group... Only group combat can bring out the maximum effect.

"Unless..." Shi Yu thought for a while. It is not impossible to save it. One is to let Chong Chong cooperate with a bunch of teammates who have mastered Solid as a Rock, and the other is to teach Eleven a matching clone skill...
