While Baron Leo and Baron Eldo were preparing to leave the city, Vincent finished explaining his method to try and cure the young lady.
Alfred was doubtful at first but this is much better than waiting for the Divine Doctor to cure Dennise after three months.
"My potions are really effective… They just take time to mature. I already have a healing potion here and I already modified them. I'm just waiting for the modification I made to take effect." Vincent explained.
Obviously, he wouldn't concoct a potion while on the carriage. He can only lie that he already made a potion and waiting for its maturity to create the best healing effect.
After all, he knows that it takes time to create a +9 potion as well. Although his success rate had increased tremendously after his Enhancement Ability became level 9, there are still chances of failure, especially during +8 and +9.
More than that, he's planning to prepare not only one +9 potion but as many as he can.
