Godslayer: from Terra, but Pre-Civilization

[Heart-throb+Arknights+God-killing+all-directed+all-member-directed] Li Yuan, whose real name is Ragrit, codenamed Idealist, is a researcher of former civilizations. But in fact, in his previous life, he was an ordinary college student who loved reading novels and playing with porridge. Until one day, he was hit by a truck while reading novels and was reborn in a new world. He originally thought that he was reincarnated into a world with extremely advanced technology, but when he saw Precious and the doctor, he knew that this civilization was probably going to end. As expected, his own civilization suffered a disaster. He followed the Doctor and Precious to Terra. After he successfully produced the extra-dimensional crystal, he brought out several bosses from the previous game Sakaz Meat Pigeon for experimental results, and he also happened to get some helpers for himself. After hearing that Demon King Amiya wanted to find a way to save the world by observing different worlds, maybe for his own dream of ascending to another dimension, or maybe to prevent Demon King Rabbit from being so tired, he resolutely took over this noble task. Who knew that something would happen to him when he traveled across the world for the first time, and he came to the world in the novel God Killing in his previous life. Fortunately, he accidentally met the god Cthulhu. Fortunately, he failed to defeat him and chose to escape. Fortunately, he accidentally fell in front of Ye Fan. But... Is all this really a coincidence? (This work is for love. Due to the personal issues of some authors, the update time is very erratic. If you mind, please leave.)
