Invincible at the Start

Read manhua Invincible at the Start:

“Ding, the unbeatable field has been unlocked by the host! As long as the presenter is unbeatable in the arena… As a nerd, Chen Changan chooses not to leave his indestructible zone before becoming immortal. He faces several creatures and ghosts from the outer world as he goes through the fantasy realm. Occasionally, when he’s bored, he rears a few adorable and kind apprentices, and by chance, he developed them into spiritual leaders who flipped the world upside down.
