Yu Tian was suddenly enlightened when he heard Tao Jun’s words.
This kid had thrown out a few hundred flying needles just now as if he was throwing trash. It turned out that they were all poisoned.
Of course, Poison Needles did not need to pursue any lethality. They only needed to hit the enemy.
There were many lethal toxins in this era. Many chemical compounds only needed an extremely small dose to easily take a person’s life.
Even if only the flying needles were used to quench the poison, that little dose was enough.
It was very difficult for ordinary people to obtain all kinds of poisons and chemicals, but an ancient martial arts practitioner like Tao Jun was naturally able to easily obtain all kinds of poisons and all kinds of raw materials to make poisons.
However, what he refined on these flying needles were not lethal poisons, but anesthetics.
This was the practice of poisoning weapons in the martial arts world.
