Yu Wan's eyes darkened. "Is there really no other way?"
Yan Jiuchao said calmly, "The only way to save him is to break through to the ninth level of the Longevity Technique."
Yu Wan pondered and said, "This should be very difficult. I remember Great-Grandpa saying that he's been lingering at the eighth level for many years, but he's still unable to do it."
Yan Jiuchao said, "Find someone who has already reached the ninth level and give him his strength."
This was impossible. In this world, no one from the Sikong Clan had cultivated the Longevity Technique to the ninth level. Even the Ghost Clan's Ghost King had only cultivated it to the sixth level.
Yan Jiuchao continued, "Or we can use the Ten Thousand Gu King as medicine and use poison to urge it. There might be a chance of breaking through to the ninth level."
Yu Wan was stunned. "You mean… to kill Great Grandpa's Gu King?"
