Reborn as a Door: Mistaken for a Supernatural Anomaly and Sealed Away from the Start

[High Martial Arts World + Supernatural Invasion + Nonhuman Protagonist + System Leveling + the Myriad Worlds]

Yan Shouyi is reborn in a high martial arts world as an old, battered wooden door.

As it happens, doors are the only passage through which supernatural beings can invade the human world.

So from the start, he is mistaken for one of them and sealed away.

"Hey! I'm not a supernatural being! Why are you sealing me?"

"Huh? This door's pretty creepy! Why can't we seal it?!"

"I'm the one who suppresses supernatural beings! Of course you can't seal me!"

While others cultivate martial arts, he cultivates as a door. While others fear the supernatural, the supernatural fear him.

The doors warriors cannot guard, he will guard. The supernatural beings humanity cannot suppress, he will suppress.

Under the Door's Laws, I am the rules.

Within the Door's Domain, no supernatural being may pass.

When the end comes knocking and the Old Ones awaken, watch him suppress the Myriad Worlds with a single door!
