After Time Travel, I Relied on Gems to Become a Saint in the World of Demon Cultivation.

An ordinary person's story of survival in another world, a legend about protection and seclusion. Chen Ziqi, a 19-year-old milk tea shop worker, woke up and found that he had traveled through time. Lying naked in the deep mountains and old forests, he was picked up by a village girl named Liu Qingqing and brought back to the woodshed. There is no law or morality in this world. Monks regard mortals as nothing, and killing people to seize treasures is commonplace. He thought he would not survive more than three days. Until he discovered a blue pendant on his chest - it could control water, heal wounds, and sense underground rivers. There is also a string of black beads on the wrist - twelve, as black as ink, unresponsive, like a decoration. An immortal master who measures spiritual roots arrives, and Liu Qingqing is found to have double spiritual roots and is about to be forcibly taken away. "Are you coming with me?" He asked. She looked at him with firm eyes. "Where you go, I go." So, he hugged her and jumped into the underground river. Three thousand miles of underground escape, countless narrow escapes to death. He met the remnant soul of Tianjizi and obtained the Origin of Space; he walked into the Valley of All Spirits and obtained the Origin of Wood; he passed through the Flame Mountain, King Kong Valley, and Lei Ze, and collected the twelve origins step by step. But he also discovered a shocking secret—— All of this is a trap set up by an old monster from the upper world who has lived for hundreds of thousands of years. He is the seventh generation "Chosen One", and the World Pearl is his "Petri Dish". When he gathers the twelve origins, the other party will come and take everything away.
