"A unique way? Do you not know what it is?" Xu Xinyuan asked.
"I do not know what it is," Miao Xinhe said. "That's the biggest secret in our stockade. It has been handed down for hundreds of years. Such a secret is only in the hands of a few people."
"Can it be considered the core secret of the Valley of Thousands of Medicine?"
"You could describe that way."
Being 80 with the body of a 40-year-old or even younger sounded unbelievable. How did he do it?
"Who else has this ability besides your chief?" Xu Xinyuan asked.
"Some elders in the stockade."
"How old are they?"
"80 to 90 years old."
"Are they in good health?"
"They are very healthy. They can probably live for another 30 years without a problem," Miao Xinhe said. "At least, it was like that when I left."
