Su Chengyu pulled over and parked the car by the side of the road, then walked along the small path to the stream at the foot of the Bull Mountain. He found a stone where he sat cross-legged, starting his Tai Shang Xuan Qing cultivation technique to absorb nature's spiritual energy.
Su Chengyu cultivated until past five in the morning, only then waking up from his focused state.
"My cultivation is becoming more robust, but if I rely solely on absorbing nature's spiritual energy for my breakthrough, I'm afraid it might take at least two or three months. Moreover, the spiritual energy around Bull Mountain is simply not sufficient for such prolonged cultivation," he thought.
There was too little spiritual energy, it was simply not enough to meet Su Chengyu's cultivation needs.
He returned to his car, drove back to the city, and on his way, he stopped to buy some breakfast for Su Xiaoxiao.
"Big Brother, when did you come back last night?" Su Xiaoxiao asked while eating a bun.
