The Global Monster Cave Is Coming: My System Is Going Crazy

Two hundred years ago, a strange rain of blood descended on the world without warning. After the rain stopped, countless space cracks turned into ferocious caves, spreading all over the world. Bloodthirsty monsters surged out like a tide, and human civilization was in danger. After using almost all destructive weapons, the world was able to hold on to the last line of defense. In the end, the top leaders of both human and demon parties made a bloody agreement for a hundred years, and the winner will dominate the future of the world. In order to survive, the old order and restrictions have been completely broken, and countries around the world have devoted their resources: on the one hand, they have made martial arts and Taoism public to all people, rekindling the fire of humankind; on the other hand, they have rapidly promoted scientific and technological research and development to create sharp blades and shields to deal with demonic disasters. Eighteen years after the end of the first human-monster war, in an era of scarred but tenacious rebirth, where crises and opportunities coexist - the story of young Chen Fan begins here.
