Earth traveler Mo Yuan awakened the power of chaos on Blue Star's eighteenth birthday, bound it to the Classic of Mountains and Seas system, and started the legend of guardianship of the two realms. As the son of the richest man in the Dragon Kingdom, he unlocked the Hongmeng Xuanjia, conquered the Chaos Divine Beast, Xi Yao Candle Dragon and other exotic beasts, and created spiritual beast armor.
Ye Chen, who is also a time traveler, was possessed by the remnant soul of Taotie and formed an army of dark alien beasts, coveting the ultimate power of the Book of Mountains and Seas, and conspired to sweep Blue Star. Mo Yuan and his partners worked step by step: from the first battle with the alien beasts in the capital city to the trial of the divine beasts in Kunlun Mountain; they established the Shanhai Group to integrate their forces and summoned eight series of armor summoners to fight against Ye Chen's Ghost Devourer side by side, crack the dark spore crisis, destroy the Arctic Ice Nest mother nest, and finally defeat the dark forces in the Kunlun Temple.
When the darkness of Blue Star dissipated, the passage to the world of mountains and seas unexpectedly opened, and alien beasts from the void attacked. Mo Yuan's troops were divided into two groups, one side guarding the Blue Star, and the other side aiding the mountains and seas, fulfilling their promise of protection with the ultimate power of "unifying the mountains and seas". In this adventure that combines Eastern mythology and supernatural battles, armor is faith, conquering strange beasts is a medal of growth, and Mo Yuan has transformed from an ordinary traveler into a guardian of two realms.
