After Being Sealed for Ten Thousand Years, I Woke up in a World of Low Martial Arts

Lin Jin, the ancient world-destroying demon lord, has been sealed away by his sworn enemy for ten thousand years. After the archaeological team broke the seal, he was dumbfounded. There was no aura in this world, only dense "iron boxes" and dazzling "luminous squares". This generation of mortals actually used the strange power called "science" to set up a peerless formation covering the world? ! His soul was severely damaged, and he was forced to escape into the body of a dying twelve-year-old boy named Lin Jin. I wanted to restore my strength in a low-key manner, but I found that the spiritual energy in this world was exhausted, and my cultivation speed was as fast as a turtle crawling. Fortunately, he knows that the fairy grass can refine medicine and set up spirit-gathering formations. This world is full of demons and ghosts. Slaying demons can actually increase your cultivation and restore your strength. As a result, the twelve-year-old child became an evil and evil being within a radius of hundreds of miles. In order to sneak into the museum and get close to the sacred stone that is displayed as a cultural relic. The World-Destroying Demon Lord had no choice but to pick up the textbook and embark on a thorny road full of five-year college entrance examination and three-year simulation. Study during the day and slay demons at night. The Eternal Demon Lord lived a different life. When he finally passed the examination and became a member of the museum, he discovered that in this world, spiritual energy was reviving, ancient seals were loosening, and evil footprints had quietly penetrated. What made him even more unsettled was that Su Wanqing, the beautiful agent from Bureau 749 who was chasing him, looked at him more and more wrongly. And his biological sister in this body, the little girl who was born with a spiritual body and was extremely dependent on him, was actually chosen by the resurrected ancient evil god to be the perfect "cauldron" to come to the world... This time, he didn't want to destroy the world, he just wanted to protect it. Protect this world with family, her, and thousands of lights.
