When ordinary happiness was shattered by the roar of alien beasts, young Qin Yang, burdened with the scars and despair of the death of his loved ones, grasped the silver dagger of fate - the Evolved Truster. He is not the chosen one, but a survivor who was brought to the forefront by tragedy, but he inherited the light of Nexus, which symbolizes the "bond".
From then on, he walked on the border between light and darkness. On one side is the fragile daily life that must hide its identity and maintain its appearance; on the other side are the terrifying alien beasts lurking in the shadows of the city, constantly evolving and devouring people. He transformed into a silver-gray giant, expanded the realm of the tower, and fought to protect it in solitude. However, the reappearance of light has also attracted a deeper peek - the TLT Night Raid Team, a secret human organization that adheres to "absolute sanity", regards him as an "isolated" risk that needs to be controlled; while the ancient darkness "Zaki" lurking in the gaps of dimensions regards him as a thorn in the side that must be extinguished.
