Prince Binglong and princess Fengsu didn''t think much about it. They had already seen that Qin Feng was different, but after cherishing each other, they separated.

    Qin Feng went forward alone and sacrificed the soul evil sword. He no longer only used the spirit body of the sword, but also used the evil spirit released from the soul evil sword to combine with his own evil spirit to push back the fire wave.

    He made rapid progress, and wanted to take in a top six grade beast, or even a high grade wild beast.

    Breaking through the sea of fire, Qin Feng has already reached the depth. It''s getting hotter and hotter all around. Originally, he is sweating, but here, even his sweat is completely evaporated.

    "Roar!"

    A Yin Yang Jiao suddenly rushes out from the deep of the sea of fire and attacks Qin Feng without saying a word.

    The spirit beasts in the sea of fire are very aggressive to outsiders.

    Qin Feng''s eyes fell on him. He found that he was a first-time seven grade wild animal. He immediately urged the soul evil sword to attack. His accomplishments broke out in an all-round way, and his powerful fighting power was revealed.

    Around him, there appeared a golden body outside the law, carrying the sword spirit body to attack together, forming a left-right attack.

    "Boom!"

    The sound of fighting came out, and it swept the sea of fire and turned into waves of fire overflowing.

    "Cover the sky pupil technique!" Qin Feng used his magic at the critical moment to make the Yin Yang Jiao fall into a dreamland. The golden body outside the Dharma immediately approached him and struck him with a sword, causing him heavy damage.

    Qin Feng quickly hands, cast "magic formula", let the law outside the gold body to control it.

    Before long, Qin Feng accepted this extraordinary Yin Yang Jiao, who had just entered the seven grade wild beast.

    "Master." Yin Yang Jiao turned into a middle-aged man, standing in the sea of fire, kneeling down to Qin Feng.

    Qin Feng nodded slightly and asked, "do you know how this sea of fire came from?"

    Before that, he was quite curious about the cause of the sea of fire. He asked Lan Yu, Prince Binglong and princess Fengsu, but their answers were different.

    There are many versions of the sea of fire. Some say that it was caused by a powerful fire spiritual cultivation. Some say that there is a sacred beast corpse with fire attribute buried in this deep place. What''s more, this sea of fire is a treasure released.

    Qin Feng is more and more curious about it, so he asks for it at the first time after accepting the beast.

    "Master, I have lived in this sea of fire since I was born, but I have never stepped into the deepest part of it. I don''t know why. But I have heard the elders of the clan mention that at the end of ancient times, there was a spirit saint with Yin and Yang spirit body who came here, and the birth of our clan may be related to it. " Yin Yang Jiao said.

    "Ancient spirit? "Yin Yang spirit body?" Qin Feng eyebrows slightly pick, did not expect to hear a new version, looking at the endless depths of the fire, said to himself, "it seems that if you want to reveal the answer, only to go to the deepest look, I do not know whether there are immortal beasts?"

    Listen to Qin Feng''s self talk, that Yin Yang Jiao urgent way: "master, absolutely must not, the deepest place inhabits our clan''s elder strong person as well as the flaming fish''s strong person, my fire sea demon domain immortal beast guards there."

    "Oh?" Qin Feng slightly a Zheng, did not expect to really have immortal beast, but also has at least two.

    At this time, he suddenly frowned and looked to the depth. His mental power actually detected that there were four figures flying fast.

    And through the mental force to see the appearance of two of them, not from a Zheng, immediately a trace of cold on the face.
