However, Xie Biao also gained substantial benefits.

Just Lin Zheyu's guidance was immensely rewarding for him.

Although they did not have the title of master and apprentice, Lin Zheyu's guidance was enough to consider him Xie Biao's mentor.

"Help me purchase some herbs."

Lin Zheyu took out the Identity Token and a sheet of paper listing the herbs and handed them over.

These herbs were required for his daily cultivation.

Although the Primordial Infinite True Skill had already been cultivated to the Second-Layer Perfection, he still needed to keep appearances.

Moreover, the purchased herbs could not only be used for cultivating the Primordial Infinite True Skill, but also be configured into formulas for cultivating other techniques.

"Yes, Uncle Master." Xie Biao responded respectfully.

After Xie Biao left, Lin Zheyu grabbed the unconscious fierce beast on the ground and walked into the miscellaneous room.

The magical puppet he captured last time had been imprisoned for so long that its inner Yin evil power had dropped to an extremely low level.

And then it stopped decreasing.

Sensing, Lin Zheyu could perceive that the magical puppet's body could very slowly absorb the Yin evil power from the air.

Although slow, it allowed it to maintain its body consumption.

Lin Zheyu unlocked the chains binding the magical puppet's hands and placed the fierce beast beside it.

Bang—

After being unlocked, the magical puppet didn't attack the beast but lunged at Lin Zheyu, who slapped it flying.

"Enjoy it well, tomorrow you will feel the taste being roasted by flames."

Lin Zheyu smiled as he spoke to the magical puppet, which was crazily biting the fierce beast.

He had asked Xie Biao to prepare the Red Flame Stone, intending to use it to start a fire to roast the magical puppet.

The Red Flame Stone is a special mineral that can burn and emit a temperature far higher than ordinary flames.

Lin Zheyu planned to use the flames from burning Red Flame Stone to test the magical puppet's tolerance to high temperatures.

After feeding the fierce beast to the magical puppet, Lin Zheyu returned to the yard to continue perusing cultivation technique manuals.

This particular cultivation technique is called the Yin-Yang Harmony Skill, a legendary Dual Cultivation Skill.

Lin Zheyu definitely wasn't planning to cultivate it, he was simply curious about how the Martial Dao could achieve the attraction of Yin and replenishment of Yang.

"It's truly miraculous!"

"Qi Blood Attraction, Yin-Yang Resonance, Yin replenishing Yang... The imagination involved is exceptionally exquisite!" Lin Zheyu exclaimed.

The Martial Dao is vast and profound; there's nothing you can't imagine, only what you can't achieve.

Recently, Lin Zheyu had purchased many odd and peculiar cultivation techniques, widening his horizons.

However, he didn't cultivate them.

These techniques were indeed 'strange,' but they weren't of much help in boosting his strength.

Lin Zheyu merely wanted to expand his understanding of the human body and Martial Dao through these unique skills, exploring the limits of Martial Dao and the human body.

At night.

Lin Zheyu fed another fierce beast to the magical puppet.

He discovered that after consuming blood meat, the Yin evil power inside the magical puppet didn't increase, but it was no longer as weak and dispirited as before.

"It seems that apart from Yin evil power, there's similar biological energy within the magical puppet that provides it energy."

Lin Zheyu muttered to himself.

The next morning.

Lin Zheyu finished his routine cultivation and came to the miscellaneous room. Seeing that the magical puppet had almost digested the fierce beast fed to it in the morning, he decided to start the experiment.

"The concentration of Yin evil power in the magical puppet's body has decreased, but its strength has recovered significantly."

"It seems apart from Yin evil power, consuming blood meat is also one of the ways for a magical puppet to enhance its strength."

Lin Zheyu muttered to himself.

He unlocked another curiosity in his heart, generally understanding why the magical puppet had such strong Qi blood.

But it was only a general understanding; the specifics couldn't be further researched due to the world's conditions and his abilities.

This made him feel quite regretful.

"Uncle Master!"

"Uncle Master!"

"There's a big event in the afternoon, with many extremely talented geniuses and famed beauties attending. Uncle Master, are you going?"

Huang Youwei shouted noisily.

Before he even arrived, his voice was already coming in from outside the courtyard.

"Hmm?"

"Uncle Master, are you planning a barbecue in the courtyard? Such leisurely elegance?"

Huang Youwei entered the courtyard, saw Lin Zheyu preparing to ignite the Red Flame Stone, and asked with some curiosity.

"Yes, I'm planning a barbecue, would you like to join me?"

"I guarantee you've never tasted it before."

Lin Zheyu glanced at Huang Youwei and joked.

"I've never tasted it?"

"Then I absolutely must taste it."

"I've tasted almost all the delicious foods in Wuling City since I was a child, but there's food I haven't tried? I don't believe it."

Huang Youwei said.

He joined in, helping Lin Zheyu arrange the Red Flame Stone into a pile.

"Uncle Master, you won't be grilling fierce beasts of the Transforming Force level, will you?"

"No, Transforming Force level beasts don't require Red Flame Stone as fuel, could it be a terrifying Grandmaster-level fierce beast?"

"Uncle Master, where did you get this…"

"..."

Huang Youwei rambled on.

But Lin Zheyu ignored him, confirmed the Red Flame Stone was ignited, and stood up to enter the miscellaneous room.

Seeing Lin Zheyu stand up, Huang Youwei looked over curiously, feeling deeply curious about the fierce beast his uncle master was about to barbecue.

"Whoa!"

"This is what you're grilling!"

"Whoa!!"

Seeing Lin Zheyu come out with the magical puppet bound tightly, Huang Youwei was instantly stunned and couldn't help but swear in front of Lin Zheyu.

"Uncle Master, don't follow Uncle Master Chen Ding. Magical puppet meat can't be eaten; it'll cause problems." Huang Youwei couldn't help but say.

Lin Zheyu, hearing this, was stunned.

"What?"

"Did you say Brother Chen Ding ate magical puppet meat?"
