Chen Nan sat motionless and cultivated.
Around two o'clock in the morning, his spiritual realm continued to break through, finally stepping into the Fourth Layer Heaven of Taming Heaven.
Chen Nan felt somewhat excited.
He had only started cultivating the Heavenly Sound of 'Om' last night, totaling about thirty hours by now. Although he had barely taken any breaks during this period, entering the Fourth Layer of Taming Heaven so quickly was already heaven-defying.
If he could continue at this pace, his spiritual power might soon break through to the Earth Penetration Realm, or even the Heavenly Realm.
The more Chen Nan thought about it, the more excited he became. He calmed his mind and continuously tempered his spiritual power with the Heavenly Sound, hoping to make further breakthroughs in a short time.
However, ideals are full-bodied, reality is bony.
