My Sniper Rifle's Power Doubles Every Day, and I Take Out Everything

A 90-year-old man awakens a System, and his sniper rifle's power doubles every day!

After transmigrating for ninety years, Lin Changming has ended up as a security guard who can't even scrape together the 100,000 yuan in tuition for his grandson.

He thought this was how his life would end, but who could have guessed that the cheat he had waited ninety years for would finally arrive!

[Sniper Rifle Doubling System bound!]

[Core function: The sniper rifle's attributes double every day!]

On the first day, the doubled sniper rifle blows an elite martial artist's target to pieces with one shot, leaving the entire crowd in stunned silence!

On the second day, he gains the god-tier talent [Bloodthirsty Sniping], which permanently steals the vitality of his slain enemies and uses it to strengthen him!

On the tenth day, its power has multiplied 1,024 times, and one shot obliterates a commander-class beast horde!

On the thirtieth day, its power has multiplied 1.1 billion times...

When the myriad races invade and the gods descend, seeking to wipe out human civilization,

a hunched 90-year-old man quietly raises a sniper rifle of dark red metal.

“So I hear you're a god?”

“Let's see if you can withstand one shot from this old man.”
