Just as everyone was still immersed in the shock and aftermath of the third Heavenly Thunder, the sky once again changed dramatically, with an unprecedented violent energy surging within the clouds.
The fourth Heavenly Thunder appeared in the night sky, different from the previous three.
The fourth Heavenly Thunder turned crimson, like burning flames, fiercely striking towards Xu Wendong.
This crimson Heavenly Thunder not only had a strange color but its might was also unprecedented.
It seemed to contain the purest fire element in the world, with every ray shining as if it were a scorching flame, able to burn everything.
Under its illumination, the surrounding air became distorted and hot as if even breathing could feel that scorching power.
All the vegetation below quickly ignited at this moment, forming a sea of fire stretching for miles, the terrifying high temperature causing the human race and demon race powerhouses thousands of miles away to reveal fearful eyes.
