Li Qingxian began studying the <Nine Heavens Divine Firmament Thunder City Grand Momentum Configuration>, exchanging insights with Xiao Shenfeng as he learned.
This momentum configuration was far more complex than every one before it. Yet Li Qingxian's foundations ran deep; he learned slowly, but without strain.
Only after studying it over and over, hundreds and thousands of times, did Li Qingxian formally begin refining the momentum configuration city.
