Leonardo touched his chin while thinking, "Can you concoct a pill that could preserve youth and extend lifespan instead? We can take things one step at a time…"
Leo realized that Merlin still had at least seventy to eighty years of life, there was no reason to be in a rush.
"That's more reasonable," the old man also nodded. He liked flexible clients the most.
"Prolonging lifespan will have side effects that would prove counterproductive in the future, those medicines are better left alone until someone is really old, or are unable to make any further breakthrough in cultivation. As for youth preservation, I can concoct a third-tier Frost Nether Nectar pill, the usage is quite simple; dissolve the pill inside clear water and let the person soak in it for a prolonged period of time."
As the old man spoke, he began to rummage through his medicinal herbs for the suitable ingredients, humming lightly to himself as he did.
