The Blood Shadow was indeed Xiong Wanchuan. After obtaining the fist technique fragment from Muo Chen, he hid within the Blazing Flame Race Territory, beginning to comprehend the fist technique shown on the fragment.
Meanwhile, he awaited others to join forces against the Blazing Flame Tribe.
He calculated that the Xiaoyang Race would use the Strongest Fist Technique to attract other Human Race Tribes.
Why should he be the one to stand out?
After a period of realization, the fragment he obtained from Muo Chen seemed exceptionally profound. It was both like and unlike the Marquis' inherited fist technique, making him increasingly uncertain.
This time, the commotion from the Blazing Flame Tribe's festival roused the hidden Xiong Wanchuan from his meditation.
He originally thought that with such a large festival scene, someone would most likely come to ambush the Blazing Flame Tribe, intending to hide away and reap the benefits as a bystander.
