The reason that he had allowed a venomous creature to inject its toxins into his body was to prove his deduction to Zhao Ya, as well as to feel how the antidote within the pond neutralized the toxins of the venomous creatures.
He had swiftly realized that the antidote worked in a similar manner to his Heaven's Path zhenqi.
Other than Kong shi, he could not think of anyone else who possessed such an ability. That was also why he had thought of making a fishing rod with his own zhenqi. To be honest, he had not really been sure whether it would work out or not!
"It's indeed Kong shi's unique zhenqi, but… why do you possess the same ability as him?" the koi fish asked questioningly.
"It's because I'm a Celestial Master Teacher as well!" Zhang Xuan answered with a chuckle.
