Signing in to the Great Desolation: from Breath of Chaos to Creation Authority

My name is Chen Xuan. I was once the laziest bastard in the ancient world. After death, I was reborn back to the beginning of the universe. In this world, the saints have not yet emerged and the heaven and earth have just opened. I just want to lie down and live my life. But if I don't sign in every day, I feel uncomfortable all over. I accidentally got a sign-in system, and I can become stronger by checking in every day. Next to the Chaos Qinglian, you can get the "Chaos Breathing Method", and pick up the Sky Ax fragments from the Pangu ruins. Others have been practicing hard for thousands of years, but I reached my full level by signing in while sleeping. I squatted outside the door when Sanqing was preaching, and I squatted in the corner to pick up leaks during the Lich War. He secretly accumulated magic weapons and magical powers, and his strength has already broken through the ceiling. The saint thinks that I am a nobody, but in fact I have fully understood the great truth. Now that calamity is about to begin and all races are competing, I still pretend to be weak. But after ten years of signing in, I already have the authority to create the world. It's time for me to set the rules in this primitive world.
