When the internal impurities reach 100%, one will definitely become a zombie. But this doesn't mean that if it's not 100%, there won't be a problem.
The first time he saw the Zombie Core, the prompt was very clear—the more impurities inside, the greater the chance of becoming a zombie!
Wang Tao didn't know how high the probability of Shao Yong becoming a zombie with 70% impurities in his body was, but even if there was a 1% chance of turning into a zombie, that would be like a ticking time bomb! You never know when it might go off...
So now, it's time to take the issue of internal impurities seriously.
Wang Tao speculated that the reason why Shao Yong had accumulated so many impurities might be due to his fusing with too many Zombie Cores!
He had a whopping 4000 Mana, which at the very least meant fusing with 40 Zombie Cores, but in reality, it was definitely more than that, perhaps even double or more!
