I Tame Beasts by Feeding

Others rely on talent for Cultivation; he relies on feeding meals for it.

Transmigrated as a servant disciple of the Wanxiang Sect, he accidentally discovers that feeding Spirit Beasts continuously grants rewards.

Upgrading Cultivation Techniques, Evolving Spirit Beasts, Devouring Bloodlines, Fusing into Progenitors...

While his fellow disciples are still worrying about forming a Contract with a single Spirit Beast.
Yu Changsheng gazes at the courtyard full of mutated immortal pets and falls into deep thought.
A fire-breathing Mystic Water Turtle, a Thunder-Manipulating Iron-Eating Beast, a mixed-fur fox that has grown nine tails.

"How can that servant's Spiritual Snake summon wind and rain?"
"Oh no! The Sect-Protecting Divine Beast is chasing that servant disciple, begging for food!"
"Why can a crow from the back mountain's servant courtyard spit out Sword Intent?"

No matter what Low Tier Demon Beast it is, he can raise it into an immortal pet!

Yu Changsheng silently tucks the "Bloodline Devouring Great Technique" back into his robes, looking at the Sect Elders kneeling and begging for his Beast Taming Secret Technique, while gently stroking the Vermilion Bird on his shoulder, which has transformed into a sparrow.
"I said this was all an accident... do you believe me?"
