Zhang Heng managed to talk to Betty for a short while during the storm. She told him the similar story she told Seth. Betty claimed she was an ancient Celtic God, and had the power to protect all sailors out at sea. She would grant her followers the power of controlling storms. This power, however, was limited for now, and Zhang Heng could only use it once a month.
According to Betty, the world had almost forgotten her name. If Zhang Heng could recruit more disciples for her, she would eventually be powerful enough to grant Zhang Heng more abilities. Once she was restored to her pinnacle, she would be able to make Zhang Heng the lord of the ocean. In order for it to come true, the goddess would need millions of disciples. This was why she targeted Zhang Heng all the while after noticing his extraordinary leadership skills.
