What Shu Liangjun brought out was a special Insect Beast named Sand Bee Queen.
This Insect Beast was fundamentally different from the ones that Fang Mu was currently familiar with.
Typically, insect beast masters form contracts with Guardian Beasts through spiritual power, generally keeping the beasts stored in the Destiny Guidebook on a day-to-day basis.
However, a contract could be made with the Sand Bee Queen without having to wake up the Destiny Guidebook.
To make a contract, one first nurtures the Sand Bee Queen with their own blood to induce her dependency on it.
Then the contracting party entices the Sand Bee Queen to nest inside their own body.
During this process, the contractor is subject to immense pain, and a contract of mutual life and death is signed between the Sand Bee Queen and the contractor while she nests.
From then on, should the Sand Bee Queen die, the contractor would die as well.
The reverse is also true.
