Prehistoric, I Refused the Free Gift, and My Organs Turned Black.

Traveling through the prehistoric world, Xuantian transformed into a high-risk species in the prehistoric times, the Black Sea Turtle. Perhaps the resentment of refusing to give in vain was too strong, so he actually awakened the organ blackening system! From then on, there was a mysterious power in the ancient world! Kunpeng saw it and walked around it! Nuwa saw it and refused to mend the sky! Leader Tongtian was even worse, even his Qingping sword was broken! Even the aloof Hongjun Daozu complained endlessly! Even if his body conforms to the way of heaven, he still can't do anything with this big and hard black turtle! This novel and its characters are purely fictitious.
