Prehistoric Times: a Wisp of Filthy Air Turns into a Saint

Traveling through the wilderness, the beginning turned into a wisp of turbidity. Pangu opened the sky, the clear air rose to become the sky, and the turbid air descended to become the earth. And he is the first ray of filthy air born between heaven and earth. Extraordinary? No, he can't even transform. A vicious beast that just passes by can make it disappear into ashes. There is no entity, no technique, and even a sneeze from the ancient ferocious beast can make him fly away. Fortunately, it is bundled with a god-level sign-in system! Sign in once a day and rewards will be distributed randomly! The first day, one year of cultivation. The tenth year: a hundred years of cultivation + low-grade acquired spiritual treasure. The 100,000th year: Hongmeng level skills + absolute defense dojo! Bite! It is detected that the host is at the birthplace of the first turbid air, triggering a critical strike in a rare location! [Ding! Obtain a special medium-grade innate spiritual treasure, the Namo Gatling gun! Yu Tian held Gatling in his hand, pointed at the beast and pulled the trigger. "Namo Gatling Bodhisattva, with six pure and depleted uranium bullets, saves the world with great mercy!" In ten breaths, the three thousand-foot ferocious beast was physically transformed into a pulp. All innate saints: "... What kind of monster is hiding under this stinking quagmire?!" He just wanted to live in peace and quiet until the end of time, but the sign-in rewards were too great.
