Time passed by second by second, and Liu Chen noticed that his Dantian was initially full, but at this moment, less than half of the Spiritual Energy remained. However, this Spiritual Energy was completely different from before.
The previous Spiritual Energy was somewhat gray-white, but now it had turned milky white. Liu Chen realized that half of the Spiritual Energy in his Dantian was impurities or not true Spiritual Energy, which he had completely filtered out. The remaining energy was actually very pure Spiritual Energy.
He tried to manipulate a breath, and indeed the higher purity of the energy made a difference. The energy flowed much more smoothly through his meridians, and the power was noticeably enhanced.
"Amazing, that old beggar actually sold me a great book!"
