MTL - The Villain’s White Lotus Halo - Chapter 4 condemn

Ye Xiao was a superior cultivator in his previous life. The three factions of the realm kill millions of people every time they attempt to seize cultivation resources. Wealthy towns turn to wastelands in just a single night. They cover up their crime with an assertion that the towns were suffering from pestilence and disasters.

They forcibly hold all the resources for cultivation, monopolize all valuable practice materials, and keep outsiders from cultivating so that only their three factions could cultivate in the realm. Ye Xiao declared war against the three factions in retaliation for their actions. He fought alone and ended up dying in vain. However, he is reborn into the mortal body of a 16-year-old boy. He will use the powers he cultivated in his last life and slaughter his way back into the Realm. The story begins!

- Description from Novelupdates

Wang Ye transmigrated to a world of summoning pet monsters and made a contract with an ordinary little green sparrow as his pet monster. To his surprise, he awakened the Pet Simulator talent that allowed him to evolve his pet monster through simulations. The pet monster would evolve based on the ultimate evolution form set by its master.

[0 years old. Little green sparrow was born. It practiced flying on a cliff. It encountered a strong current and dropped from the cliff. It was covered in wounds.]

[1 year old. Little green sparrow learned how to fly after much hard work.]

[2 years old. Little green sparrow saw a mysterious bird dancing in the air and sank into deep contemplation.]

[5 years old. Little green sparrow got better at flying. It comprehended the skill of Sky Dancing.]

[5.5 years old. Little green sparrow got bolder and attempted to learn how to swim. It plummeted into a spring from the cliff and drowned. It acquired the personality of Unstoppable Courage.]

After the simulation ended, the pet monster could acquire either the skill or the personality it mastered during its life in the simulation.

After going through a certain number of simulations, the pet monster had a chance of evolving into the predetermined ultimate evolution form.

Wang Ye took a glance at his little green sparrow that was pecking away at rice. Without hesitation, he decided on its ultimate evolution form – the divine beast Angewomon.

His little green sparrow looked at him with a look of confusion.
