Actually, Song Yun didn't know. Although the super-grade potion is good, it doesn't instantly enhance someone's power to such a degree. If it did, wouldn't everyone become a Super Saiyan?
A super-grade potion, if given to someone like Lord Ghost King, could increase their power by about fifteen to twenty percent, and for someone like the Divine Calculator, it could increase by around seventy percent.
This varies from person to person, depending on an individual's potential and to what extent that potential has been developed. The more potential has been developed, the less there is to develop, so the increase after using the potion is less. Conversely, the less potential has been developed, the more the power increases after taking the potion.
Initially, Song Yun had almost fully developed his potential.
But Song Yun took two bottles at once, and that was overwhelming.
