In 2077 AD, a "mountain and sea catastrophe" suddenly occurred around the world. Unknown cosmic rays penetrated the atmosphere and awakened the energy of the alien beasts from the "Book of Mountains and Seas" sleeping deep in the earth. Modern civilization collapsed instantly. Zombies, aberrant beasts and the alien beasts from the Book of Mountains and Seas coexisted. Cities were reduced to ruins. Secret realms, spiritual veins, and ancient ruins were spread all over the world. Human beings awakened to various superpowers, and the law of the jungle became the only law. The source of the disaster points directly to the dragon veins of the Kunlun Mountains. The level of the alien beasts and the strength of the secret realm are all bound to the Mountains and Seas region. The closer you get to Kunlun, the greater the risks and opportunities.
