Human Cannonball was quite fast, but even so, the red spot was still pointing east after Roland flew for two hours.
He stopped and built a small building to take a rest.
After his mana was recovered, he continued his journey to the east.
His magic regeneration was slower than his consumption. So, without using the Mind-Calming Necklace, Roland could only fly two hours and rest five hours in order to replenish himself.
It was because the capacity of his mana had soared after his level-up. Though his magic regeneration had been slightly increased by Roland's Zeal, it couldn't catch up with the growth of Roland's total mana.
After all, he had added all his stat points on Intelligence, which decided the basic damage of his spells as well as the upper limit of his mana.
Based on the direction of the black gem, Roland kept flying eastward.
