When King Ning and Mei Sen attacked Fei Hou, they summoned their Martial Souls.
King Ning's Martial Soul was a gigantic spider with eight legs, its body shimmering with multicolored light patterns. It was the Seven-Colored Spider among Martial Souls, known for its extremely potent poison.
The virulence of its poison was so intense that mingled with the air currents, it could kill a peak of the Tenth Order Late Stage expert with just a trace breathed in, causing death from terrible toxin within a dozen breaths.
As King Ning summoned his Martial Soul, he underwent Soul Transformation instantly. His arms became covered in multicolored light patterns and grew poison stingers resembling spider legs. When he fiercely punched towards Fei Hou, his arms and their poison stingers flared widely.
As for Mei Sen, his Martial Soul was a kind of black vine with long spines, which was obviously poisonous as well. Following King Ning, Mei Sen underwent Soul Transformation and attacked Fei Hou.
