The Insect Expelling Technique left by Han Yuan of the Thousand Spirit Sect was indeed very exquisite and profound.
This so-called Insect Expelling Technique included not only secret methods for commanding Demon Insects in battle, but also many secret techniques related to insect breeding.
Beast Taming and Insect Expelling might seem similar at a glance, but upon detailed examination, there are significant differences between the two.
For Beast Taming Cultivators, as long as the bloodline of the Demon Beast is high-grade, there is no need to put much effort into beast rearing.
But Insect Expelling is completely different.
Apart from a very few Demon Insects with extremely bizarre and powerful individual capabilities, the majority of Demon Insects need to rely on numbers to exhibit formidable combat strength.
How to expand the populations of Demon Insects and how to command more Demon Insects overwhelm the Insect Cultivators' breeding capabilities.
