In summary, aside from the Level 9 tier, the battles at lower tiers, whether it's the six million armed human forces and seventy-eight units of Endless Journey, or the thirty-million-scale silver-armored zombie horde amassed behind Tang Ye, their purpose is to deplete the followers and hordes of the Zombie Kings' offspring.
Zombie Kings are indeed terrifying, but their followers are troublesome enough as well. After all, the number of high-level zombies is far beyond human reach. Just one Radiation Zombie King has over two hundred Level 8 followers under his command! This doesn't include the followers under other Zombie Kings.
In comparison, dealing with Zombie King Kamutos is actually the simplest because he has no followers; he's a lone commander. However, dealing with this entity using ordinary methods is not feasible, and this pressure all falls on Su Sigui.
