Wu City Preparatory Academy's resources were naturally fully open to Chen Nan. He came to the library and entered its highest floor, the archive that housed T-grade cultivation techniques.
T-grade cultivation techniques were already the highest-grade techniques within Wu City Preparatory Academy's authority. Unless one was a special student, one could not select them.
Chen Nan wandered about inside, picking through the T-grade cultivation techniques with an absent-minded air.
The truth was, the techniques here held no particular appeal for him.

In a sense, Chen Nan had thoroughly optimized Thunderclap Art, elevating it into something of a higher grade. Here, there was not much talk of elemental counters, so mastering an attack of one attribute was enough for most situations.

Pure defense consumed more in every respect than offense.
