A veteran player of “Starry Abyss” and a Meteor Fall Master known as Ace Bro, Li Zi came to the game world with his system template, arriving at the era of the game's beta version.This was the worst of times.Cosmic forces and financial magnates colluded, causing The Gate to the cosmos to be shut, planets' resources exhausted, even sunlight monopolized.It was also the best of times.All the Extraordinary Systems had just started, and in this era, only he possessed the final version patch as a Meteor Fall Master.While people reveled in the smoke of plasma cannons, Li Zi had already torn apart warships with Gravity.As Special Ability users proudly indulged in their awakened abilities, Moonlight had already become a servant to Li Zi.When the Interstellar Fleet crossed the Galaxy, Li Zi had just ignited the forty-second Stellar, illuminating the entire cosmos.“People have been trapped on the ground for too long and have forgotten that this Starry Sky should belong to us all,” he said gently, holding a black hole in his hand while facing an indescribable native Evil God.
