The Protagonist Is Invisible

Yun Shen traveled to a soul crystal in the Soul Master Continent, and then discovered that upgrading to fight monsters, snatching resources, intrigues... All had nothing to do with him from now on. He just needs to hide quietly behind the host, move out a small bench, eat, complain, lie down and drink. The only problem is: What should I do if my host is too noob? Should you consider changing it? Small ones are hidden in the mountains, large ones are hidden in the city, and finally they are hidden and cannot be found. Irfa: "I died miserably in my previous life, and I am about to die young in this life as well. I couldn't find someone to express my last words to, both times. Life is so difficult..." Yun Shen: "Oh, then come on." Leader of Black Shark: "The upgrade was not successful today. If we continue like this, even a bunch of young men will be shocked. Life is so difficult..." Yun Shen: "No way, no way, no discussion, I still refuse today." Reinak: "Recently I always feel like someone is spying on me, but unfortunately I have no evidence." Yun Shen: "That's your illusion. I was obviously looking at it openly." The above is the crooked version. For detailed plot, please refer to the main text. Concept: A story of journey and adventure.
