Knights descend upon Douluo Continent; death awaits if they do not fight.

Huang Fei transmigrated to the Kamen Rider universe. Unfortunately, he arrived in a world based on the Kamen Rider Ryuki universe. Countless Kamen Riders from different worlds gathered here for an endless free-for-all, slaughtering each other. Only the last one survived, and only the last one was the victor. Everyone else was doomed! Without fighting, they would either be killed by other Kamen Riders or by monsters! Huang Fei contracted a white tiger and transformed into Kamen Rider White Tiger. The White Tiger, a legendary beast in Chinese mythology, was a creature of divine power, controlling the element of metal and killing. The more it fought, the more lives it killed, the stronger it became. Thus, he endured countless days and nights of battle, emerging from a sea of ​​blood, wiping out all the Kamen Riders except himself, becoming the ultimate victor and the sole survivor. At this moment, he was covered in blood, both from Kamen Riders and monsters. His entire body radiated an unparalleled, terrifying killing intent, chilling to the bone. He also acquired the abilities of all the Kamen Riders he had killed. Having gathered the abilities of all Kamen Riders, he became the strongest Kamen Rider across all realms, the God of Slaughter, White Tiger! Just as he ascended the throne, a completely new world descended upon him. The information from this world surprised him. It was actually Douluo Continent from his previous life! And it was even the first part, during Tang San's time! Huang Fei: "Interesting. Riders descend upon Douluo, and those who don't fight die!" From then on, the landscape of Douluo would be completely changed! Everyone lived in fear!
