Hungry, cold, and hurt, before he could figure out the situation, a cold mechanical voice exploded in his mind: [Ding! The immortal system is successfully bound! Congratulations to the host for gaining eternal life! Immortal! Eternal and everlasting! When the catastrophe came and swept across the heavens, the being who had been behind the scenes for eternity slowly opened his eyes. No one knows that the master of the Tianji Pavilion who stirred up the storm, the mysterious alchemist whose inheritance was lost, the nameless passerby who left legends in the ancient ruins...
