The Demon Mercenary Corps is the mortal enemy of Ren Feng's Wind Mark Mercenary Corps.
Back in the day, after Ren Feng founded the Wind Mark Mercenary Corps, their ranking skyrocketed, quickly climbing to second place, directly threatening the number one ranked Demon Mercenary Corps.
So, both sides had friction, and the tension between them accumulated over time, finally exploding during a mission. During that mission, the Demon Mercenary Corps plotted against Ren Feng.
In that ambush, the Demon Mercenary Corps allied with several other Mercenary Corps to take down Ren Feng because the rise of the Wind Mark Mercenary Corps disrupted their entrenched interests.
But unexpectedly, Ren Feng's strength was astonishing. In Sand City in the Sahara, he maneuvered alone against five major Mercenary Corps!
Moreover, in the end, he single-handedly slaughtered all one thousand one hundred and fifty-four members of the five major Mercenary Corps.
