Although a lot of vicious snakes were placed on the training field, they were all non-poisonous snakes such as Beauty Rat Snakes, lndian Wolf Snakes, Red Banded Snakes, Mandarin Rat Snakes, Mock Vipers, King Rat Snakes, Sawtooth Neck Bronzeback Snakes, Brahminy Blind Snakes, and etc. In order to create confusion, some venomous snakes such as Cobras and Stejnegeri Pit Vipers with their fangs removed were placed together with those non-venomous ones. Under such circumstances, even if someone was able to identify a few non-venomous snake species, they would be startled and panic from the sight of those venomous snakes that were placed intentionally.
Yan Liqiang bought those snakes from the medicinal merchants in Pingxi City. Getting the rats was even easier since the people of Pingxi City only needed to send the rats caught by the traps.
