Lufa was reborn with thousands of years of memories. Within three months after the "Netherworld Legion Rebellion Day", he gave up his original armed rebellion plan and used "hibernation and infiltration" as the core strategy. While pretending to be loyal to stabilize King Peel and the top military officials, he secretly repaired the internal cracks in the Netherworld Legion, collected royal dirt, and instigated key figures to rebel, laying the foundation for the subsequent overthrow of the tyranny. At the same time, he faced the dual test of "memory backlash" and "historical inertia."
