Wang Tao had thought that all crystal cores came with side effects, but that did not seem to be the case so far.
Every crystal core contained impurities, but that did not necessarily mean it had side effects—the side effects here referred to obvious ones, such as light-sensitive eyes or excessive obesity.
Impurities themselves were a kind of side effect—if too much accumulated, there was a risk of turning into a zombie! But that was the result of long-term accumulation. The two were not the same...
As for this crystal core, Wang Tao had been surprised to see that it had no side effects. But the moment he saw the ability description, he understood.
No wonder the ability was called Self-Destruct—this was a damn self-destruct ability! It could only be used once in a lifetime! To Wang Tao himself, this Self-Destruct Crystal Core was just as useless as the Glutton Crystal Core he had already used up as material.
In any case, neither of these two crystal cores was something Wang Tao would choose to fuse with.
Of course, these two crystal cores would definitely still be useful to other people.
After all, becoming an Esper would significantly enhance one's physical fitness. Even without using the ability, it would not be a loss.
Then Wang Tao thought back over the differences between these crystal cores.
So far, he had obtained a total of four Zombie Crystal Cores.
They were two Shockwave Crystal Cores, one Glutton Crystal Core, and today's Self-Destruct Crystal Core.
Other than their different types, all four crystal cores had different qualities. Only their purity was the same—all were 50%...
So Wang Tao had reason to guess that Tier 1 Crystal Cores were probably all 50% pure. As for higher-tier crystal cores, he did not know whether their
