After visiting the medical center, Ryzel went back to his laboratory and continued reading the research results of Mr. Hanes' experiments on cleansing potions.
It seems that just like other researchers the results weren't ideal. It was clearly shown that Mr. Hanes used different materials and even used different dosages, but the result stayed the same.
If the results of his mother's experiments were also the same, then he could proceed with his idea first before focusing on making a cleansing potion.
When reading countless research results by different research he noticed that some herbs would always have the same function.
When he researched them further when he was still at the academy all the herbs have a calming effect.
Even the research of Mr. Hanes, which also uses different materials, has such herbs in them.
