It was also because Zhou Tian happened to glance across that world at the time that he obtained a conclusion he would otherwise have had absolutely no way of reaching.
According to Zhou Tian's earliest assumption, it was because he was a living being from a Different World that Heavenly Thunder was drawn down to attack him back then. In that case, if it were living beings native to that world, then by Zhou Tian's theory they naturally could not possibly receive the same treatment he did, being constantly bombarded by those bolts of Heavenly Thunder.
Yet in fact, at the beginning Zhou Tian did not understand the situation. But after he had let those Heavenly Thunder strikes rain down hundreds of times, by chance he discovered that the living beings within that world at the time also seemed to be enduring the attacks of Heavenly Thunder. Once Zhou Tian discovered this, it inevitably had a corresponding impact on his actions.
