[At this time, you had already undergone nineteen rounds of the baptism of thunder power in small lightning zones.]
[Your physical body had been greatly strengthened, increasing by more than double from before.]
[However, your body also neared its limit.]
[You knew you were not far from breaking your limits.]
[Even more delightfully, your Heavenly Thunder Physique was continuously being perfected under the constant tempering of the thunder power... You felt a new force emerging within your body!]
[As your body approached its limit, you began searching for more small lightning zones.]
[But at this time, small lightning zones were nearly impossible to find; you couldn't locate any.]
[Worse yet, as time passed, even the number of medium-sized lightning zones decreased continuously.]
[You understood that if you delayed any longer, you would have no choice but to venture into large lightning zones.]
