Sequence adventurers roaming between two worlds

In the Potions Sequence, I dominate with my inherent power; in the Adventure Continent, I subdue others with my extraordinary mechanics! ...A Primordial Mirror granted Leo the ability to travel between the two worlds. Initially, he was cautious, but soon, discovering the strengths and weaknesses of each world, his eyes gleamed with a strange light: In the Potions Sequence world, extraordinary abilities were unparalleled, but various extraordinary resources were scarce, making advancement difficult. In the Adventure Continent, resources were unimaginably abundant, but the class skill mechanics were outdated, making him weaker among those of the same level. "Since that's the case, then I'll take the essence and discard the dross." Relying on potions, he became invincible among those of the same level in the Adventure Continent, seizing abundant resources! Utilizing his class rank, in the Potions Sequence world, he "crushed those of higher levels" from top to bottom! "I am the pinnacle of the gods, and the ultimate source of absolute unity and the overflow of all things." "Now, I lack nothing!" [Two Worlds] × [Potion Sequence] × [Fantasy Adventurer]
