A Plants vs. Zombies Achievement: Kill 10 Giant Zombies

No way.

Wang Yu quickly activated an Ice Mushroom Card.

"Boom!"

A Huge Ice Mushroom sprouted and exploded.

The Elite Giant Zombie in the distance was just breaking free from the freeze when Wang Yu's Ice Mushroom froze it again.

Still, he had no intention of doing that. Brute force wasn't the answer.

He needed to think
