Listening to the delightful notification sounds from the system, Noah felt elated. Sitting at home, experience points were falling from the sky. He sold nearly a hundred electromagnetic railgun defense turrets, making a neat profit of 10 billion catalysts. Each time these turrets killed a zombie, he would gain the corresponding experience points, just as if he had killed the zombies himself. His character level rose from 6 to 8.
Not only was he leveling up while lying down, but the speed of leveling was also quite fast. He believed he would definitely reach the maximum level of 10 before the end of the third phase. In the third phase, the first four days featured relatively fewer zombies of lower levels, providing humanity with one last period for reaction and preparation.
