Potion Tower

Jacob left the bank building after he was done with his bank account matter and his concerns.

In the end, he even bought that Zodiac Money Transfer Device for twenty thousand gold coins, since it could come in handy frequently.

Furthermore, he now had a deeper understanding of Zodiac Taurus Bank and how advanced the Rare Region was compared to the Uncommon Region, despite still being in the uncommon region.

Afterward, Jacob decided to visit that Potion Tower before calling it a day.

When he reached the Potion Tower, those two burly guards' eyes narrowed. They instantly recognized Jacob from his getup, who 'mocked' them early.

However, before they could berate him and chase him away, Jacob showed them five gold coins, "I want in."

"Go." Unwillingly, they took the coins and let him pass.

They didn't want to cause a scene without any good reason. Since Jacob was paying the entrance fee, they can't stop him or they will suffer terribly.
