Teng Yi unexpectedly arrived in the Three Kingdoms period at the end of the Eastern Han dynasty, but this world was a little different: evil spirits ran rampant, and the common people suffered terribly. By chance, Teng Yi awakened an Armor Summoning System. Using the power of the Emperor Armor, Zi-O, and Decade, he rescued Cao Cao, Liu Bei, and Sun Quan and became sworn brothers with them. He granted them the power to summon armor, and together they fought the evil spirits and drove them into the wilderness.
Before long, however, alien creatures and interstellar monsters descended one after another, invading Earth. The group was unable to stand against them, but fortunately, the mythical beasts from the Classic of Mountains and Seas awoke, along with the ancient gods of both the East and the West. They helped Teng Yi and the others defend their home planet. Through their tireless efforts, they eventually sealed evil at the edge of the universe and ushered in peace.
