"Oh?"
Jian Wushuang was surprised.
He only knew that the Blood Mountain Sword needed to merge with unique skills to enhance its power, but he did not expect that the Blood Mountain Sword had such a high fusion requirement.
"It means that the power of the Blood Mountain Sword can't soar in a short period of time," Jian Wushuang said inwardly.
He had just created an advanced rank one skill, so he did not know when he would be able to create a superior rank one skill, let alone create a supreme one.
"Take it slow," Gu King said.
"You have to go step by step, Jian Wushuang. You still have not cultivated for very long, so you have more room for growth. Don't worry."
"Understood." Jian Wushuang nodded.
At this point...
"Hmm?" Jian Wushuang raised his eyebrows.
"What's wrong?" asked Gu King.
