The Iron Blood Brotherhood had grown to around five million troops. Of those, three million were its main fighting force, while another 1.6 million came from the Children of Stone and Chaos Warrior clans.

After Zhuojiu and Bai Shi reported the situation, Lu Yang discussed it with Malthus and the others. They decided that not every soldier needed to learn the Origin Battle Form. Thus, they selected the melee bloodlines most suited to using it and brought them into Blood Purgatory with Lu Yang.
The Qingtian Beast, Silver Emperor, Twin God Descendants, Fire King Descendants, Wild Sky Army, and Sky Pillar Army were all suited for close combat, so they formed the main fighting force of this expedition.
