Nationwide Tower Defense: I Can Upgrade Defense Towers Without Limit!

Su Chen transmigrated to a bizarre world where everyone played tower defense.

In this world, humanity was trapped in perilous high-rises and couldn't take a single step outside.

Every day, countless dark creatures attacked humanity: zombies, witches, undead, strange beasts...

Beyond the high-rises lay endless darkness.

After transmigrating, Su Chen awakened an Infinite Upgrade System from the start!

"Ding! The Alloy Arrow Tower has killed 100 monsters and can be upgraded to an Alloy Arrow Fortress!"

"Ding! The Super Turret has killed 1,000 monsters and can be upgraded to an Infinite Cannon!"

"Ding! The Shield Hero has killed 5,000 monsters and can be upgraded to an Iron Warrior!"

While everyone else trembled in the darkness, Su Chen had already built his own city!

While everyone else struggled desperately to survive, Su Chen had already launched a counterattack against the darkness!

Super-evolved titanium alloy warriors!

A galactic fleet!

Laser starships!

Su Chen had turned the whole world's tower defense game into a feast of monster slaughter!
