The moment he was reborn before slaying the dragon, Li Xiao tightened his grip on the blade, but turned around to protect Gu Jin behind him - the boy he once regarded as his old enemy turned out to be the incarnation of a dragon soul that had been sealed for thousands of years. All the immortals wanted to kill the dragon to prove the way of heaven, but only Li Xiao saw through it: What showed in Gu Jin's eyes was not evil, but a thousand years of loneliness. He was willing to bear the name of betrayal, tear up the sacrificial formation, and use his own essence and blood as a guide to reverse the dragon contract. When the flames burned the sky and the divine soldiers poured out, Li Xiao and Gu Jin stood back to back on the collapsed altar. One vowed to protect the enemy to the death, and the other finally called out "brother" for the first time. This is no longer a dragon-slaying battle, but two souls torn apart by fate, working together to rewrite the beginning of the sky.
