The just-begun Heavenly Tribulation was still sporadic, with clumps east and patches west, and each having different attributes—some were Purple Cloud Thunder, some were Qingxiao Thunder, some were Wind Fire Thunder, and some were Heavenly Gang Thunder.
Gradually, the summoned tribulation clouds increased in number; they repelled and attracted each other based on different attributes, producing various wonderful uses and gathering together.
Small patches merged into large ones, and the area covered grew; once different attributes of tribulation clouds fused, they produced unexpected changes, generating even more powerful Heavenly Thunder.
Each person's situation varied, with differences in the time and intensity of the summoned Heavenly Thunder—some thunder arrived first, some later, in dribs and drabs, eventually leading to ever-growing accumulations of tribulation clouds.
