After the experiment, Shi Yu was hungry, tired, and sleepy.

Originally, he planned to clean the courtyard and rooms first, but looking at his current state, he decided to just make do for one night, and definitely do it tomorrow.

"It's getting late, I'll go prepare dinner now."

"Eleven, you rest for a while, I'll call you when dinner's ready."

Shi Yu turned his head and said to Eleven.

The Iron-eating Beast behind the tree: ｜д•´)!!

Rest?

It shook its head vigorously.

How could that be?

It finally awakened the Hardening skill, how could it rest?

It was already too far behind its peers.

It had to hurry up and train.

It wouldn't feel comfortable eating dinner without completing two hours of training.

Shi Yu, who had telepathy: ???

Shi Yu was shocked. The zookeeper Lin Xiuzhu was right, this Iron-eating Beast was indeed a bit strange.

It clearly wanted to eat delicious food, but felt uneasy eating dinner because it hadn't trained yet???

You're too disciplined.

"There's no need to be so anxious. Today is a special situation, it's okay to rest well," Shi Yu advised.

The Iron-eating Beast shook its head violently.

"Never mind..."

"Then you can practice the Hardening skill in the yard first," Shi Yu said.

"Awoo—" Eleven nodded, completely forgetting that Shi Yu wanted to eat its bamboo shoots, and its expression gradually became serious.

As soon as it said practice, it started... It looked at the surrounding walls.

This gaze startled Shi Yu.

"Wait a minute, first practice maintaining and controlling the Hardening skill."

"Strive to quickly harden a certain part of your body in the shortest amount of time."

"Put the other things aside for now."

How to practice the Hardening skill was actually very simple.

The training methods for this kind of low-level skill were generally very basic.

The breeding manual that Lin Xiuzhu gave him had a clear record.

The proficiency of the Hardening skill was divided into four directions.

Duration, coverage area, control speed, and Hardening strength!

The Iron-eating Beast's gaze just now clearly meant it wanted to practice Hardening strength.

The basic method for practicing Hardening strength was something Eleven had already mastered at the breeding base, which was to temper the normal body and the hardened body like steel.

In other words, keep getting beaten or using your body to destroy things.

Eleven was fine before it mastered Hardening, but now that it had learned Hardening, if Shi Yu allowed it to practice Hardening strength here, his home wouldn't be safe!

So Shi Yu quickly stopped the restless Iron-eating Beast and asked it to practice the maintenance and control of Hardening first, skills that wouldn't cause too much commotion.

"We'll talk about Hardening strength training later."

After Shi Yu advised it, Eleven scratched its face and nodded, alright then.

At the same time, Shi Yu felt relieved.

However, he felt a little tired.

It was a good thing that his pet was self-disciplined, but why did he still feel tired? So strange...

"Huff."

After arranging the Iron-eating Beast, Shi Yu stopped thinking too much. He glanced at the green caterpillar in the corner, found a bundle of wire from his house, and used tools to make a simple birdcage to raise it.

After conducting an experiment with the green caterpillar and seeing the skill proficiency of the green caterpillar's silk increase, Shi Yu had an idea to make money.

Depending on the breeding method, the green caterpillar's silk had a wide range of uses.

The clothing field, the medical field, and the industrial field all used the green caterpillar's silk.

Therefore, whether in Pingcheng or Icefield City, there were specialized breeding bases for raising green caterpillars to produce silk.

However, although the quality of silk produced by this kind of assembly line was not low, it was not very high.

The highest quality silk was often produced by Pet Tamers who specialized in breeding green caterpillars.

Many channels were willing to buy the silk produced by these Pet Tamers' pets at high prices.

The higher the quality of the silk, the higher the purchase price!

This kind of thing was actually very common. Not only silk, but many parts of pets' bodies had a wide range of uses. There were not a few Pet Tamers who regarded raising pets as a business.

Pet Tamers who contracted with Wood-type pets would ripen spiritual plants, and Pet Tamers who contracted with healing-type pets would help people see doctors. These were all ways for Pet Tamers to earn extra money.

So Shi Yu thought, since he didn't need to put in much effort to improve the green caterpillar's skill proficiency, and silk acquisition was the most common business on the market, why couldn't he first use this method to earn a pot of gold?

When training the Iron-eating Beast... take the time to train this green caterpillar as well. Anyway, this guy can currently eat ordinary plant leaves, which are everywhere just like green caterpillars.

When he had piled up its silk proficiency to the Perfect level, the quality of the silk would definitely not be low.

In this way, selling a bundle of silk could instantly alleviate the family's financial pressure.

"Ji—" The green caterpillar in the cage lay down dejectedly.

Shi Yu looked at it with a smile and said, "Sorry, I'm really forced by life."

It was a pity that the green caterpillar didn't have high intelligence. Otherwise, if it were any other pet, it would definitely rush to take advantage of this good thing that could quickly increase skill proficiency.

…

Night.

Shi Yu and the Iron-eating Beast were both very tired after dinner.

Constantly using the Hardening skill during training had consumed a lot of Eleven's physical strength.

After it finished eating, it immediately fell asleep, its round body spread out in a ball.

Although it had come to an unfamiliar environment, it slept soundly and peacefully, and after falling asleep, it revealed a smile it didn't have when awake.

Shi Yu smiled as he watched the Iron-eating Beast smack its lips even in its sleep.

Being able to develop this personality was partly due to talent, but perhaps the different experiences caused by individual differences were indeed what it cared about.

It clearly liked to eat, but it wasn't willing to eat unless it completed its training. Was it worried that it would be abandoned again if it didn't perform well?

As the Iron-eating Beast's Pet Tamer, Shi Yu could vaguely feel its thoughts. In Eleven's view, the reason why its previous Pet Tamer didn't choose it and didn't recognize it was because it performed too poorly.

"Don't worry, I won't abandon you no matter what."

It was very common for Pet Tamers to change pets, especially some Pet Tamers who had grown up. They would choose to replace their previously contracted low-race pets with higher-race pets. Shi Yu didn't know what level of Pet Tamer he could become, but he was determined that he wouldn't abandon every contracted pet.

It didn't matter even if the contracted pet's race level was low. At worst, he would risk being drained to secretly learn two Divine Skills!

Speaking of which... did Iron-eating Beasts have an evolution path? Shi Yu really didn't know this.

Next, Shi Yu recalled Eleven into the Beast Space. Resting there would allow it to recover and rest better than outside, and it could sleep more comfortably.

After that, Shi Yu himself lay on the bed and fell into deep thought.

"How about not summoning it back? I haven't experienced sleeping with a giant panda as a pillow yet..."
