The next morning, the sun was shining, and the calls of birds and green silkworms echoed in the surroundings.

Shi Yu woke up naturally, then groggily got out of bed. After mechanically washing up, he lay back down.

"Right, I need to go out later." He muttered to himself.

At this time, his condition had mostly recovered. He checked the Skill Index, and the eight-hour cooldown had also cleared, indicating he could use the Skill Index teaching skill again.

Today, he planned to try teaching the Harden skill, but if a skill with no rank required eight hours to recover, the consumption of a low-rank skill would definitely be greater.

So, he planned to go out and buy some nutritional supplements to use after teaching the skill.

Whether it was summoning, recalling, using beast-taming talent to strengthen pets, or pets growing in the beast-taming space, the beast-tamer would experience some consumption.

Therefore, not only do pets have various nutritional products and medicines, but there are also many supplements on the market for beast-tamers.

Shi Yu had just become a beast-tamer and didn't know much about this, but he was sure he could buy them, as the small ads for these medicines were almost everywhere.

He researched the Skill Index's cooldown time yesterday. The time should be calculated based on normal rest.

If he consumed supplements or meditated, the time would accelerate. It wasn't a completely fixed cooldown time, only related to his current state.

When the Skill Index determined his physical condition had recovered enough, he could proceed to the next round of teaching.

Actually, this was much friendlier. In the future, he could carry a water cup with him, soak some otherworldly wolfberries, and carry a box of tonic pills in his pocket. Teaching mid- and high-level skills might not be impossible.

Moreover, after becoming a beast-tamer, his physique would become stronger and stronger. The situation where teaching skills was difficult might only be limited to now.

In short... he had to control himself. Shi Yu didn't want to participate in a beast-taming competition in the future and need an Iron-Eating Beast to push his wheelchair into battle.

"Eleven, keep sleeping in there. I'll let you out after I buy something."

After notifying the little Iron-Eating Beast through telepathy, Shi Yu resisted the temptation to take a nap and chose to go out.

"Right, I forgot to say hello to you."

After Shi Yu walked out of the room and into the yard, he suddenly remembered something and looked at the persimmon tree.

In the birdcage hanging on the branch of the persimmon tree on the left, the Green Silkworm had already woken up.

It was quite detached... leisurely eating leaves inside. At this time, there was a pile of persimmon leaves inside, and some were half-eaten.

Shi Yu thought, this should be the Green Silkworm using its silk to roll them over. With its silk skill proficiency reaching the proficient level, it was easy to do this.

At this time, the Green Silkworm ignored Shi Yu, just blankly munching on leaves and looking at the sky.

Why was it, a silkworm, locked in a birdcage?

But from another perspective, it could be seen as locking the birds outside the cage... greatly improving safety.

"Speaking of which, this Green Silkworm is a bit strange..." Shi Yu muttered to himself before leaving.

Other Green Silkworms ran towards nutritious plants, pursuing growth and evolution, but this one was fine, completely without any pursuit, running to eat the leaves of his free-range persimmon tree, content with the world.

No wonder this Green Silkworm was malnourished.

If he hadn't used the Skill Index on this Green Silkworm and taught it Silk, it probably wouldn't have been able to undergo a second metamorphosis until the end of its lifespan.

"I'll pick some more common plants on the roadside when I come back to improve its diet..."

He couldn't afford the spiritual plants and rare fruits that could promote the growth of Green Silkworms in the breeding base. There were plenty of ordinary plants on the roadside.

As his future silk supplier, it couldn't die too quickly due to malnutrition...

Hang in there, the Green Silkworm race has a chance to evolve into a cocoon after its growth level reaches level ten.

At that time, they would spit silk to wrap themselves into a cocoon. The higher the silk skill proficiency, the higher the probability of successful evolution, and the greater the individual differences.

So, as long as this Green Silkworm stayed obediently in Shi Yu's birdcage, it was entirely possible to defy fate in the future...

...

"It's changed a lot compared to my memory."

After going out, Shi Yu walked on the streets of Pingcheng, once again marveling at the changes here. What best reflected these changes were the high-rise buildings and the pedestrians on the roadside.

Whether they were beast-tamers or not, raising a pet seemed to have become a trend in this world.

The more prosperous the beast-taming culture, the closer the relationship between people and pets.

He saw an uncle riding a four-wheeled vehicle, with a leashed icefield dog resembling a husky pulling him along.

Good heavens, real green travel, natural and pollution-free, just a bit hard on the dog.

Well, besides dog-walkers, there were also cat-walkers.

Shi Yu saw a girl chasing a gem cat all over the place.

If walking a dog was like riding a horse, then walking a cat was like bullfighting. Basically, it wasn't the person walking it, but it walking the person.

This uncontrollable situation... most likely the cat owner wasn't a beast-tamer, and the two hadn't signed a contract. The gem cat was being kept as a pet.

The gem cat resembled the ragdoll cat on Earth, very beautiful, and stronger in combat than the Green Silkworm.

And similar to the Green Silkworm, its evolution method was public, and the upper limit was not low.

As long as you had a rare "cat's eye gem", you could allow the gem cat to gain different racial abilities based on the type of gem, completing the evolution.

The rarer the cat's eye gem used, the stronger the power the gem cat would gain.

Basically, gem cats without cat's eye gems could only be pets, while gem cats with cat's eye gems were high-quality battle pets.

Shi Yu didn't linger his gaze for long. That was an ordinary gem cat, without signs of evolution, probably in the basic training stage.

After all, the price of cat's eye gems was more expensive than the gem cat itself.

Gems were natural resources, extremely scarce, but cats could continue to breed. Over time, the price of cat's eye gems went up, and the price of gem cats went down...

At this time, while experiencing the current atmosphere of Pingcheng, Shi Yu was looking for a pharmacy.

Finally, he came to a place called "Baicao Hall Pharmacy," four thousand meters away from his home.

The layout here was no different from pharmacies on Earth. After entering, Shi Yu saw various boxed and canned medicines in various glass cabinets. If he had to find a difference, it might be that pharmacies in this world were for both humans and beasts.

Due to cultural differences, even doctors who specialized in treating humans knew a little about treating animals.

For no other reason than to make money. It was just a matter of taking an extra certificate, and the income would at least double.

"Is there anything you need?"

After Shi Yu entered the pharmacy, the young physician at the front desk asked.

"Do you also buy silkworm silk here?"

Shi Yu immediately noticed a sign in the pharmacy, which listed various medicinal materials that the pharmacy could buy, one of which was the silk of the Green Silkworm.

"Yes, but we need silkworm silk spun by Green Silkworms that feed on several special medicinal materials, and the quality must reach high-grade. After the ingredient detection is qualified, we can directly purchase it here."

"The types of medicinal materials are written above. You can take a look."

"Okay." Shi Yu nodded and seriously looked at it.

Depending on the food they ate, the properties of the silk spun by Green Silkworms were also different. For example, the silk required by some clothing factories required the silk to have various anti-cold and heat-insulating properties.

Clothes made of anti-cold silk were very expensive. Like the snow-capped mountains outside Icefield City, an anti-cold exploration suit was essential for ordinary beast-tamers who wanted to explore there.

The cultivation direction of the silkworm silk purchased by this pharmacy for medicinal purposes was, of course, that the silk needed to have specific ingredients.

As for the so-called high-grade quality, it could probably be equivalent to requiring the Green Silkworm's silk skill proficiency to reach the master level. If the silk skill proficiency reached the perfect level, the price would be several times higher.

After looking at the purchase price, Shi Yu swallowed. Counting the inheritance and various subsidies, considering that he had to repay the loan every month, he and the Iron-Eating Beast could only last for a year at most.

If he didn't make a name for himself within a year, such as becoming a professional beast-tamer, he would have to honestly find a breeding base to work and clock in, and the funding chain for cultivating the Iron-Eating Beast would be broken.

However, if he could stack the Green Silkworm's silk to perfect quality, even considering the cost of food, he could completely afford to raise the Iron-Eating Beast with just one worm. Opening a Green Silkworm breeding farm would directly lead to financial freedom.

It seemed he had really found a business opportunity. The bug-catching boy was actually himself.

"Are you a beast-tamer? Do you intend to sell silkworm silk?"

When Shi Yu was studying carefully, the young physician casually asked, bringing him back to reality.

"Not for now. Please get me two bottles of that medicine." Shi Yu pointed to a partition.
