Lu Yuan traveled through the prehistoric era and turned into a black-feathered crow! The starting hell difficulty is: sealed in a small cave, waiting for death in despair. A turning point has arrived - the "Tribulation Simulator" is activated! Rely on simulation and deduction again and again. The shocking conspiracy of the big guys at the top of the ancient pyramid was gradually revealed by him! I originally wanted to lead my little brother to become the King of Crows, but he couldn't help but get involved in layers of murders. What's even more embarrassing is that the system doesn't have a manual! It's all about your own research. When the "Choose Three from Six" reward interface popped up, Lu Yuan was so excited that he almost took off. But when he saw the options clearly, he was dumbfounded: "If you didn't give me six options, how could I do it? What's the use of these 'rags'?" It wasn't until later that he realized that these "tatters"... Were truly heaven-defying opportunities! ............ The Crow-Eating Beast covered his face: "Brother... Brother, stop smoking. We have no grudges." Ancestor Styx was heartbroken: "Half of my blood river has dried up in one go?! Hou Tu was surprised: "I never expected that a being like you could be born in the world today. " Nuwa was puzzled: "How come your understanding suddenly rises and then falls? " Zhunti and Jieyin said: "This boy has a predestined relationship with Western religion. " Dao Ancestor Hongjun was surprised and doubtful: "This son... Is not included in the deduction of Heavenly Dao? Strange! " Leader Tongtian looked confused: "I just want you to revive Jiejiao... How did you become a saint? ! " Follower Jiang Tuantuan: "Boss, I want to be with you forever! " Lu Yuan: Thank you for the invitation. I am in the ancient times and have just left the Demon Suppressing Monument. I just want to lie down, but the bosses are forcing me to turn over! From the prisoners under the Demon-Suppressing Monument to the strange figures that make all the saints pay attention. Emulator? I simulate all over the world!
