Under normal circumstances, whether he is cultivating insects or birds and beasts, he would tame them first before breeding them.
Because if they're not tamed, they're uncontrollable.
The stronger they are, the harder they are to control.
Even Qin Niu himself could be killed by them.
Such tragedies have occurred several times. Some bold Insect Masters or Beast Tamers, overly confident in their abilities, capture wild beasts or poisonous insects which they continuously fail to tame. So, they think of first showing goodwill to build a relationship.
It will then be much easier to tame them later.
But after they've nurtured the creatures to become more powerful, the creatures break out of their enclosures and turn on their 'masters'.
Qin Niu conducted this experiment to see if he could pave a new way for wealth.
