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.

I woke up in my sleep, and a strange door appeared in my home…Behind every door is a strange world.

In the nightmare world, Jiang Cheng added the news from the strong man to the fat man, and he almost cried when he heard the latter, “If you die here, the whole family will stand upside down and bleed?”

“Is such that.”

“Then I don’t think you are too scared?” The fat man widened his eyes.

Jiang Cheng turned his head and said in a very formal tone: “Because I am an orphan.”
