Douluo: People Kill Indiscriminately in the World

[System] [Do not wash] The world is so vast that life is difficult to comprehend, so seek to be ordinary and have long-lasting peace. "My name is Yu Chang'an, extra Yu, long and long, safe and peaceful. I am more socially anxious." When Yu Changan, an ordinary, socially fearful young man, gave up his youthful fantasies and settled for mediocrity, he was selected by a system. "Ding, the invincible pretense system has been successfully bound. Please ask the host to prove it." "6, I refuse." "Rejection is invalid, please pretend to prove it!" "Come on, I'll lie down for a while." "..." "Ding, the host's request has been approved, and a star train will be provided for the host to travel on his behalf." But he finally accepted being ordinary, so he decisively rejected the system. All pretentiousness and protagonists have nothing to do with me. Whoever likes to toss can go. So the system gave him a star train and let him go home on his own. It's a pity that the system is so stupid that it actually asked him to complete tasks in every world to earn fares... "6, You are really 6! Gou's batch, your system!" The Nine Sun Holy Body that was loaded with a time bomb was of no use, and its head was lowered. The only golden pupil felt like two small light bulbs at night. System, can you trick me a little bit? Yu Changan was furious and chose to lie down, but he felt it was inappropriate and could only force himself to work hard. So he began his wonderful journey across the world.
