The Feathers wanted to use Han Sen to boost their reputation, but Han Sen ignored them. He stuck to practicing with his geno arts and his knifeskills.
Because his core talents were so good, Han Sen's progress with Under the Sky was coming along quickly. When he practiced with Yun Suyi, however, he suppressed it.
He continued to practice with her because she could be a witness for him. If anyone doubted his ability to learn and correct Under the Sky, she would be able to speak in support of him. He really did only learn it faster than others.
Having been at Sky Palace for three months now, Han Sen's Jadeskin was finally going to ascend. A strange power flowed inside his bones and flesh. Leveling up to Earl meant generating a spirit.
Jadeskin's power had a light element. As the power increased, a jade light would cast a shadow across Han Sen at all times. It was very weird.
