Because he didn't know the specific effects of each tonic, Shi Yu didn't dare buy too much at once.

After careful selection, he chose three kinds of tonics, buying a little of each.

Five ginseng baby whiskers, worth 250,000 yuan (minimum purchase of five).

A small bottle of hundred-flower queen bee royal jelly, worth 300,000 yuan.

Five not-so-full Divine Beans, worth 500,000 yuan (minimum purchase of five).

Shi Yu spent 1,050,000 yuan all at once... Nearly one-tenth of his initial 10 million yuan was gone.

Shi Yu felt a pang of pain; how could he be so extravagant?

However, when he thought that he might be able to teach Eleven all the high-level skills with these tonics, and by the way, max out the proficiency of several skills, he accepted it.

Money is meant to be spent!

Moreover, this million yuan might not have as great an effect as buying tonics for himself compared to buying food and nutritional products for Eleven.

"This is still the cheapest batch of tonics..."

Shi Yu sighed. After placing the order, he fell asleep again.

When he woke up again, it was already evening.

If he stayed up late meditating or playing on his phone at night, it might affect his condition during the day.

Shi Yu decided to continue sleeping, but the problem was that after sleeping for an afternoon, he wasn't very sleepy anymore.

So, after preparing dinner for the two pets, Shi Yu could only teach the Green Silkworm in the birdcage in the yard the Bug Silk skill.

Only after his stamina declined did sleepiness strike again.

This Skill Encyclopedia seemed to also have the function of treating insomnia; not bad.

The next day, the sun was shining brightly.

Shi Yu woke up refreshed. He had originally planned to go to the Zhushi Martial Arts Hall today, but a text message changed his mind.

The tonics he bought yesterday were already being delivered and had arrived in Bingyuan City, and would arrive today.

"The efficiency is really fast..."

"In that case, I'll just wait at home today."

In the morning, Eleven was pondering Thunder Palm in the yard, the Green Silkworm continued to sleep, and Shi Yu was meditating.

Around noon, when Shi Yu was about to prepare lunch, the door of their house was knocked on.

"You have a package."

"Coming."

Because of the experience of the community's warmth delivery last time, Shi Yu quickly responded, afraid that his house would be blown up again.

He opened the door and saw a young man in a blue delivery uniform. Next to him was a giant bird more than two meters tall, fully armed.

The giant bird had strong muscles, gorgeous golden-brown feathers, and sharp eyes. Although it looked domineering, it was currently just doing the work of a tool pet, with a huge package box hanging on its body.

[Name]: Sky-Piercing Wings

[Attribute]: Wind

[Race Level]: High-level Transcendent

[Race Skills]: Wind Wings, Tearing Claws, Super Vision, Wind Blade

The young man took the box containing the tonics from the package box hanging on the Sky-Piercing Wings and handed it to Shi Yu.

"Please sign for it."

Shi Yu: "..."

They actually used a Transcendent-level creature to deliver packages.

Sky-Piercing Wings was the bird-type pet with the highest level and comprehensive strength among creatures of the Transcendent race.

"Are you a professional Beast Tamer, young man?"

Shi Yu asked casually while signing the form.

"Yes, I just joined the job this year. Please take care of me if there's anything I don't do well." the young man said.

Shi Yu received the goods and felt depressed.

Is the threshold for the delivery industry so high these days? But the salary must be very high, after all, the resources delivered by that website are all high-end goods.

After signing, Shi Yu handed the delivery form over.

The delivery boy took the delivery form and then looked at Shi Yu.

This little customer... is a trainee Beast Tamer, right?

Speaking of which, why did he buy so many advanced tonics... Even he, a professional-level, doesn't need so much.

Well, never mind, never mind, forget it. He couldn't possibly be lacking at this level, right?

"Then I wish you a pleasant life."

"Thank you."

The bird-riding delivery boy and Shi Yu thanked each other, and this order was considered complete.

Afterward, in the yard, Shi Yu began to take out the tonics one by one, handling them carefully, for fear of scratching or breaking them.

He first took out a bottle containing five green little beans. After looking at the accompanying instructions, Shi Yu called Eleven over.

"Eleven, come here quickly."

"Ying?"

Eleven, who was playing with electricity in the yard, ran over happily.

At this time, with the more advanced tonics, Shi Yu's heart surged.

[Skill]: Multiplication

[Skill Level]: High-level

[Introduction]: Special type ability, can shrink or enlarge the body. In the shrunk state, strength is weakened and energy recovery speed is accelerated. In the enlarged state, energy consumption increases and strength increases.

[State]: Can be taught

Shi Yu planned to teach Eleven the Multiplication skill first.

As for why it wasn't the Intimidation skill that could give Eleven the qualifications of a king, or Absolute Sleep, which could improve his and Eleven's training efficiency, it was simple... because the Multiplication skill was more interesting!

Anyway, with so many tonics, it's all the same whether he teaches the three high-level skills sooner or later. Shi Yu chose the Multiplication skill, which he found more interesting, first.

In the enlarged state, Eleven can increase its combat power. In the shrunk state, it can accelerate the recovery of physical strength. It's not a loss to learn this skill first.

Shi Yu took out a Divine Bean and put it in his mouth.

"Encyclopedia, teach!"

As Shi Yu chose to teach, his right hand once again filled with a white halo.

At this time, seeing this familiar scene, Eleven was stunned.

It panicked.

Is the Beast Tamer... going to let it gain without effort again?

"Aowu!"

It had just independently learned Thunder Palm, and the Beast Tamer was going to use a cheat to erode its mind... it was really...

Eleven took the initiative to stretch its head over. Since it couldn't resist, it might as well choose to enjoy it.

At worst, it would work harder afterward to make up for it.

In this way, the white light representing the experience of the Multiplication skill flowed into Eleven's body, and Shi Yu's legs began to weaken continuously.

[Cooldown Time]: 168 hours

The cooldown time for the skill Bug Silk, which is unrated, is around 8 hours.

The cooldown time for low-level skills is around 24 hours.

The cooldown time for mid-level skills is around 48 hours.

Shi Yu originally thought that the cooldown time for high-level skills was 72 hours, but... it more than doubled.

In a state of extreme weakness, Shi Yu felt like he was going to die. He quickly swallowed the Divine Bean.

In the next second, a surge of energy began to flow in Shi Yu's body.

Just as the introduction said, in a very short period of time, this Divine Bean burst out with massive nutrients and began to nourish Shi Yu's body.

One second, two seconds, three seconds... A surge of power suddenly gushed out of Shi Yu's body.

[Cooldown Time]: 48 hours.

Although it didn't completely restore Shi Yu, it immediately reduced the consumption to a range he could bear.

Suddenly, Shi Yu felt like he hadn't taught a high-level skill, but rather a mid-level skill.

Based on his experienced weakness after teaching mid-level skills, Shi Yu immediately felt better again.

It seems... that high-level skills are his current teaching limit. Before his physique has a significant leap, even if he has more powerful tonics, he must never touch super-level skills...

"This is simply killing me—"

Shi Yu breathed out a long breath, not caring about the dirt on the ground, and sat down on the spot, looking at Eleven in front of him.

At this time, Eleven was closing its eyes slightly, digesting the experience of the high-level skill Multiplication.

Shi Yu stared at it for nearly a minute before Eleven came back to its senses.

"Did you master it?" Shi Yu asked.

Eleven nodded vigorously.

"Then show me what it looks like to get bigger."

As Shi Yu spoke, the chubby Eleven nodded seriously and solemnly used the Multiplication skill.

In the next second...

Buzz!

Eleven seemed to emit ripples around its body. Accompanied by the ripples, its body began to tremble slightly. Then, as the vibration of the transparent ripples increased, its body began to enlarge in circles!

Buzz!

Buzz!

It didn't suddenly become larger, but rather the body size gradually increased in proportion. Limbs, torso, head, and fur were all changing at this moment!

"Aowu!!!"

After a while, an Eleven that was still chubby and not much different from before, but with a height and size that had doubled, appeared in front of Shi Yu.

At this time, Eleven slowly waved its unaccustomed arms, only feeling that the energy in its body was rapidly being consumed. But at the same time, its strength seemed to have increased by more than just a little.

It was probably the difference in strength between a young panda and an adult giant panda in reality.

In this state, Eleven felt that if it encountered those long-spiked wild boars again, it could slap them away by more than ten meters!

Eleven's eyes were full of fighting spirit.

"Gulu Gulu..."

However, its stomach had no fighting spirit.

Eleven: ..@_@|||||..

In less than ten seconds, Eleven began to feel dizzy, after all, it had consumed a lot of physical strength during training just now.

"Alright, alright, shrink back quickly."

Called Multiplication, there is one times, two times, three times, naturally there is also one-half times, one-quarter times... that is, the so-called shrunk state.

After Shi Yu, as a Beast Tamer, sensed Eleven's power after enlarging, he quickly told it to shrink back to restore its stamina.

In the next second, Eleven was like a deflated balloon, first quickly shrinking back to its normal size, which was about one meter tall.

Then, it continued to shrink, and soon, it shrunk to become a half-meter-tall, round and short real chubby ball.

In this state, it was closer to Eleven's appearance when it was younger. It looked harmless to humans and animals, and its big eyes revealed innocence.

"Ying." Eleven touched its stomach and made a grievance cry.

It was still hungry even after shrinking.

"Cough, it seems that for entry-level Multiplication, increasing the volume by one times and shrinking to one-half times is already the limit."

There was still some proficiency missing from Shi Yu's envisioned giant Iron-eating Beast the size of Ultraman, and the mini Iron-eating Beast the size of a key chain that could stand on his shoulder.

But it was already very good, after all, it had just learned it.

"Alright, let's have dinner then." Looking at the small Iron-eating Beast, Shi Yu was in a good mood.

"Let's eat like this in the future, it'll probably save a lot of food expenses." He joked.

Eleven: (｡◕vev◕｡)??? What!!!
