Han Sen did not purchase any hyper geno art on the evolver level before he reported to Daphne, because he had no idea he would end up in such remote areas and lose the access to the Saint Hall.
Although on Daphne there were also hyper geno arts provided to soldiers for free, Han Sen was not interested in the ordinary stuff.
This S-Class Saint Hall license was different from an ordinary license in that he was able to use it on Daphne to trade for the hyper geno arts and geno solutions stored on the warship.
Han Sen did not hesitate and chose hyper geno art. When he was picking, he had a slight trouble.
Because Daphne was not the Saint Hall, only 3 to 4 types of S class hyper geno arts were stored on board, so Han Sen had not too many options.
Normally speaking, hyper geno arts on the evolver level were all focused on changing the structure of one’s body cells.
