There Is a Mountain at the Beginning, I Rely on the Mountain to Eat the Mountain

[Survival game + swallowing fusion + single male protagonist + no cp + exotic pets] [This is the first time for a young author to write a long novel. Don't be surprised if his writing is bad. It's a bit heavy-handed, because it involves gluttony, so there are descriptions of eating yourself, so if you can't accept it, don't read it. The bad news is that Jiang Yu accidentally ate poisonous mushrooms that he picked and fried himself while eating at a farmhouse. His face suddenly turned blue, foaming at the mouth, and he lay there with a burp. Even worse news is that all young and middle-aged humans on the earth have been transported into the doomsday game, and they can only rely on themselves to survive. The good news is that the second he died happened to be the moment the teleportation started, so he didn't die. As soon as he opened his eyes, Jiang Yu found himself in a broken hut on the mountainside. He had also awakened a special poisonous characteristic, which was equivalent to being immune to all poisons and could eat anything. A side effect is that you get hungry very easily, and if you are too hungry, you will fall into an unconscious state. Originally, he thought that he would be safe now that he had come, but Jiang Yu said that he could just pick up some random things to fill his stomach and survive. As a result, Jiang Yu had to work hard to develop in order to have a full stomach and for the two-person duel that happened once every ten days in the novice stage, and then he accidentally became the number one in the entire list, and also became the strongest in his plane. But this is not the end...
