My name is Xuanfeng. I am a modern ordinary person who traveled to a prehistoric world where chaos first emerged. The Hongmeng has not yet been judged, the heaven and the earth have not yet existed, the energy of chaos is permeated, ferocious beasts are rampant, and survival is difficult. As soon as he woke up, he was involved in the dangerous place of the fairy mountain. He had no cultivation and his life was hanging by a thread. I accidentally got a check-in system, and you can become stronger by checking in every day. Sign in to the fairy mountain to get the Qigong method, sign in to the secret realm to get the innate spiritual treasure. Others' ten years of hard work are not as good as what I get from signing in in one day. While my peers are still struggling to build foundations, I have mastered the power of chaos. From a minor practice in refining qi to conquering the heavens, no one can rival him. After signing in hundreds of millions of times, I finally became the Lord of Chaos, in charge of the origin of all realms. This novel and its characters are purely fictitious.
