Inside Ling Han's body were two spiritual oceans, one on the bottom as earth, and one on top as heaven, symbolizing the yin and yang.
When he allocated his Origin Power, he could choose one of the two spiritual oceans, but if necessary, the two large spiritual oceans could both circulate at the same time. One yin and one yang, although opposites, it could give terrifying bursts of spiritual power, making his power skyrocket to the seventh layer of the Spiritual Ocean Tier.
Against a nobody like Zhao Hong Cheng, he naturally didn't have to use his full strength; the earth spiritual ocean circulating was enough of a power support.
He mainly experienced the subtle changes in the War Elephant Fist, improving upon his fist path.
All arts in the world aimed for the the same end, so if he could form seven flashes of Sword Qi, then it also meant he could reach seven flashes of Fist Qi. However, there had to be a process, and he was reducing that process now by battling Zhao Hong Cheng.
