{The rating for this work has just come out! It will rise later~}
[Delta Force background story and world view] + [System] + [Refreshing read]
Eighteen years have passed in a single moment!
It wasn't until Reis sold to the Tower of Babel that Zhang Zhao realized—this was actually Delta World!
Zhang Zhao was in a panic, facing the extremely high mortality rate of brain-computer interface experiments!
Fortunately, the Hafcoin instant kill system has been awakened!
One Half Coin at the start instantly kills the Shadow Skill Pack!
Become an even more perfect ReLink brain-computer interface user than Wuming!
Hafk, believing he had complete control over Zhang Zhao, sent him to infiltrate GTI!
At that time, the selection process for the GTI Golden Generation had just begun.
The Tower of Babel operation has not yet taken place;
Saeed has not yet captured Dam Zero;
Reis is also planning the Diamond Queen Hotel;
Demoulan was not disfigured yet;
Hudson was not yet the ambitious performance minister;
Gheros has just arrived at Tidal Prison;
......
after many years,
The will of the world descends, and players invade, only to discover a figure standing atop the Tower of Babel!
"My name is Zhang Zhao, the sharpest blade in the world..."
"There's no boss in the Tower of Babel; perhaps I can make up for that!"
