Lin Feng looked speechlessly at the massive creature blocking the cave entrance—a colossal eagle with nine heads, each head showcasing icy cold eyes staring intently at him.
The nine-headed thunder eagle, a fierce bird descendant from primordial variants, had claws that could easily penetrate a cultivator's body.
Most importantly, the nine-headed thunder eagle excelled in dreadful Thunder Attacks, capable of launching such attacks from each of its nine heads.
Lin Feng had only read about and seen descriptions of the nine-headed thunder eagles in the "Classic of Mountains and Seas"; this was his first time encountering a real one.
Even cultivators from the Yin Yang Realm wouldn't engage in battle with such a fierce bird.
Because the nine-headed thunder eagle was not only fiercely aggressive but also extremely fast. Its speed was such that it could even dodge attacks from cultivators of the Yin Yang Realm.
