[Decisive killing! Invincible! No Madonna plot! 】

When a thunderbolt tore through the night and a blood moon descended, the world changed from then on, all beasts evolved, vegetation grew wildly, and wisdom was opened.

In just one night, the whole world fell into bloody chaos. The powerless human beings couldn’t stop the mutated beasts and the plants that started the evolution of Ganoderma lucidum, and countless human beings became their meals.

However, the people with the tattoos were horrified to find that the tattoos on their body surface also revived, giving them incomparably powerful power.

Gu Changqing travels back to the eve of the world’s mutation three years after the world’s mutation.

In his previous life, he was reduced to a low-level laborer because he had no tattoos on his body. Now he has traveled back and survived the troubled times. The first thing he did was to invite the world’s top tattoo masters to engrave the world’s top ten demon tattoos: Rahu, Qilin, White Tiger, Black Dragon, Death, Shura, God, Skeleton, Great Sage, Nezha!

Because he knew that engraving tattoos after the changes in the world would not awaken them and become powerful combat forces.
