Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

The snake, Yu Yaoyao, transmigrated into a third-rate actress who was only a pitiful cannon fodder in the novel.

This little actress met a dark accident, her diamond husband was robbed, her son died miserably, and she was at the lowest peak of her career. Ultimately, she became paralyzed in the end.

Yu Yaoyao is determined to change everything!

From there on, she became a mistress, a loving mother and practiced the art of acting through multitasking!

At the other end of the line…

The male lead looked patiently at Yu Yaoyao straddling his waist: Get off!

Yu Yaoyao: I won’t! Husband, that film emperor is extremely ugly! I’m so scared I can’t even sleep at night properly ~ let’s make a second child—calm down, don’t be frightened!

Yu Yaoyao: …Isn’t that me?

Director: As an actor, when I say ‘start’ your tears should immediately fall…oh, that’s enough, there’s no need to cry more.

Yu Yaoyao: It’s nothing.

Qin Chen was transmigrated to the Taiyi Holy Land where he became a servant in charge of sweeping the floor. However, on his 16th birthday, he was rewarded with a system where he was rewarded whenever he signed in at a new place.

When he signed in at the Empire Ruin, he was rewarded with the strongest Chaotic Holy Body and the Chaos Emperor Scripture.

When he signed in at the Demon Sealing Land, he was rewarded with the Probationary Royal Armies.

When he signed in at the Alchemy Palace, he was rewarded with the Divine-grade Alchemy.

When he signed in at the Herb Garden, he was rewarded with an Immortality Elixir.

When he signed in at the Empire Palace, he was rewarded with the Emperor-grade Divine Art, Revival.

…

Qin Chen thought he could just spend the rest of his life signing in at different places until he became invincible.

However, when the ruin of the Great Kingdom appeared inside the holy land, people from other holy lands, prestigious families, and even ancient empires gathered to defeat the All-Powerful Demon King who appeared with the ruin. The Demon King had killed countless people and had planned to destroy the Taiyi Holy Land.

Qin Chen was left with no choice but to step up. When he killed the Demon King with a single slap, he sighed, “Why do you guys have to force a mere servant to act?”

Transmigrating into a poor and mistreated young lady's body, what will the craziest alchemist of the seven realms now do?
