Now Zhou Tian doesn't have much room for activity, so if he wants to detonate the crystal bombs, it poses no issue whatsoever. But for Zhou Tian, detonating those crystal bombs may be a trivial matter, yet the consequences of detonating that heap of crystal bombs will certainly require his attention.
If Zhou Tian detonates only a small number of crystal bombs, then the destructive power he causes won't be too significant at that time. In the end, it's hard to say Zhou Tian's action would be entirely meaningless, but even if he detonates the crystal bombs, it would probably result in the same outcome as before. And obviously, Zhou Tian is certainly unwilling for his detonation of the crystal bombs to have no effect.
