5 parts Ongoing Han Xiao, a hardcore gamer from "Star Sea", was transported into the game by a mysterious force from the east, turning his player panel into an NPC. He went back to the time before the game's public release and chose the most difficult profession - Machinist. Warships sailed across the starry sea, starlight mechs danced like dragons, and the devastating energy cannons destroyed the heavens and the earth. There were also endless mechanical armies waiting quietly in his inventory. One person, a whole legion! If it weren't for the appearance of players, this book would be a serious and solemn story about crossing into a different world... As an NPC, he had all the normal functions of an NPC towards players... issuing quests? Adjusting affection levels? Teaching skills? The number one beauty in esports only wanted to learn skills? Sorry, I sell my body, not my skills. Wait, I know all these players. Alright, it seems the real world has also gone back in time to ten years ago.
