Swoosh!
Uno swam through the sea without any restrictions as if were a sea creature himself. With the Underwater Breathing Pill that he had consumed earlier, he did not encounter any problems along the way.
As for fighting, Uno did not encounter any sea monsters along the way, which made his journey quite smooth and easy.
He traveled for at least two days (in-game time), wandering in the sea of nothingness and spending one more pill that let him breathe underwater.
The sea was quite deep, but he did not explore too deep on it as the pressure was getting stronger and he was unable to withstand its strength the further he advanced. He could only stay on the level where the pressure was where he could withstand while spreading his senses in every direction to scan the surroundings.
He was also using a special method to see further ahead as he tried to find the said temple.
