So only divine flesh, energy water, or mind fragments can be traded in the trading platform.
Legion-10 came to the conclusion that only items composed mainly of spirituality can enter and leave the virtual world. So only such items can be traded.
After getting the information they wanted, Legion-10 returned to the selling trading platform with his mind and approached the stall with the rank 4 divine flesh that they needed.
There was also the divine flesh of the pathway of slavery. There was more than one seller of the divine flesh of slavery.
Legion-10 was surprised at first to see this, but then he remembered that telepaths are the least afraid of slavers. Telepaths can protect their minds and can even destroy the minds of slavers, so they have nothing to be afraid of about strengthening slavers.
Besides this logical reason, there was also the fact that this place was the best place to sell the divine flesh of slavers that they killed or happened to stumble upon.
