This Host Is Obviously Invincible but Is Too Nerdy

"With the keyboard in the left hand and the mouse in the right hand, I am the best otaku!" "You said I was just eating and waiting to die? That's because you don't understand how happy a salted fish is!" Chen Changan, who has just graduated from college, has just started his happy life at home, but who would have thought that he would travel through time all of a sudden! You don't have a male protagonist character yourself? I'm afraid I won't be able to get out of the Novice Village if I go out to level up! "Ding, the host has opened the invincible field! As long as the host is in the field, he is invincible!" System: "Host, please go out and complete the mission as soon as possible." Chen Changan: "Get out? It's impossible to get out. It's safe and comfortable in here, and the system talks nicely, so why should we get out?" System: Can I restart and change the male protagonist?
