Zhao Hai kept diving. After a while, he felt the wave-like thing. He knew that he was about to enter the flame space. It was really strange. Above the wave-like boundary, one wouldn't know that there was another space below. It was full of flames, so one couldn't see it from above. However, as long as one passed the boundary, they would see a huge space filled with flames. If an ordinary person were to enter this space, they would most likely be immediately turned into ashes.
Zhao Hai entered the flaming space and looked around. There was nothing to see here. It was like an independent space, half the size of the sky. However, it was strange to be surrounded by flames, but it didn't affect Zhao Hai. He had the bloodline of the Phoenix, so the flames only made him feel comfortable and warm. They wouldn't cause him any harm.
