Demons Are Rampant, I'm the Only One Who Can't Sign In

Huang Tao traveled through time and came to a world where demons were rampant. Here, there is a beast with a body as big as a mountain and eyes like the sun. Here, there are monsters that devour the sky and the earth, and there are immortal blood demons. The human race is weak and relies on the treasures left by the immortals to grow. Everyone can open Xianzang every day, similar to a sign-in system, and receive rewards. Huang Tao accidentally discovered that he could swallow Xianzang. From then on, everyone else who signed in was working for him. "Sign in and get the Wind Spirit Step!" "I have swallowed other people's treasures and obtained the true body of the wind spirit!" "Sign in to get the Blood Demon Immortal Body!" "I have devoured other people's treasures and obtained a gluttonous body!" So what if you can sign in? They are all working for me!
