Call Me the Ghost Messenger

After the eternal night, terror resurfaces.

Ten miles of desolate graves, eerie singing.

An old man searching for his arms, a headless infant...

They ceaselessly piece together their bodies, erupting with even more terrifying auras.

In the barren lands, a single severed hand can destroy heaven and earth.

In this dark, despairing environment, a dimly visible post office appears...

A mysterious young man, a postal vehicle traveling through the void...

One blood-red letter after another becomes a taboo whispered among the people...

----The Ghost Messenger.

PS: No female lead or a single female lead (don't guess wildly, at least it's not Zhou Han)

Main characters: Wang Ye, Zhou Han,
