Akina Little Moon

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?”

I Became Invincible After Sweeping The Floor For 70 Years

[Congratulations, host. You have checked in to the five-colored altar. You have received the reward, the Silver Moon Scroll!]

[Silver Moon Scroll: A one-time consumable item, a failed product forged by an ancient great emperor. It can release an attack comparable to a quasi-emperor-realm expert, and it can also devour mysterious substances to make itself stronger.]

Qin Chen had never imagined that the thing in his hand was a failed product of an ancient great emperor.

That being said, he didn't have any leeway to choose at this point. He was already very happy to be able to obtain this Silver Moon Scroll.

Qin Chen recalled that the Silver Moon Scroll seemed to be able to devour mysterious substances, which would allow its power to become even stronger than just akin to a quasi-emperor.

However, he currently didn't have any other thoughts.
