At night, Xin Ling was sitting inside the cave hollow he used for sleeping. Now, he was following Ning Long's advice.
"Slowly absorb qi. You have to merge the qi power you absorb from the Sun's power during the day with the yin in this cave," said Bai Zhe.
Xin Ling frowned and tried to separate yin and yang power in his Dantian. After he followed Ning Long's instruction, he found that when the two powers combined, they would cause a powerful qi current.
"Calm down. Gradually increase the qi that is combined together until I tell you to stop," said Bai Zhe.
Xin Ling obeyed without protest; he was in pain from having to suppress the qi in his Dantian.
"Ack. Ning, I cannot hold it back any longer." Xin Ling felt that he was starting to be unable to control the power.
"Not yet. You have to increase the qi." Bai Zhe sent his power to help so the energy channels would not be damaged.
