After returning home, Han Sen showed Yan the tutorial of Holy Angel and asked her to memorize it.
With the holographic demonstration, it was not difficult to learn. Being intelligent, Yan memorized Holy Angel after watching just a few times.
On the next day, the geno solution compatible with Holy Angel was delivered to their home by the staff of Saint Hall. Han Sen asked Yan to drink it in accordance with the instructions.
Because practicing hyper geno arts could generate a burden on one’s body and each hyper geno art had different effects, most hyper geno arts would have to be practiced along with the using of its correspondent geno solution.
An S-Class hyper geno art usually came with three bottles of geno solution, so it could be practiced by up to three persons.
If the matching geno solution was not used, Saint Hall would be exempt from any obligations and medical bills if there was an accident during the practice.
