The reason Zheng Hai is so confident is because his innate ability is the unparalleled "Innate Divine Eye".
With this talent in his possession, not only is his eyesight extraordinary, but abilities like long-distance vision and night vision are extremely easy for him.
Moreover, the Innate Divine Eye greatly enhances the cultivation of eye secret skills. Any eye secret skill he practices will develop rapidly, and when used, their power surpasses others'.
Thus, Zheng Hai has cultivated many types of eye secret skills, including one called "Charming Electric Eyes", which possesses a strong charm effect, used to seduce women with guaranteed success.
Except for a few women with exceptionally strong willpower, most women would fall for his electrifying eyes.
However, Zheng Hai has typically used this on women, and against Secret Spirits, it wasn't particularly effective.
After all, this ability only works on the opposite sex, and isn't very useful on various other Secret Spirits.
