Knights Descend on Douluo: Fight or Die

Huang Fei transmigrates to a Kamen Rider universe. Unfortunately, the world he arrives in is based on the Kamen Rider Ryuki setting. Kamen Riders from countless different worlds have gathered here for an endless battle royale, fighting and killing one another. Only the last person standing can survive, and only the last one is the winner. Everyone else must die! If you don't fight, you'll either be killed by another Kamen Rider or by a monster! Huang Fei contracts a White Tiger and transforms into Kamen Rider White Tiger. The White Tiger is a legendary divine beast from China, in the same class as the gods. It governs the killing power of metal, growing stronger the more it fights and the more living creatures it kills. Thus, after countless days and nights of slaughter, he emerges from a sea of blood. He kills every Kamen Rider but himself, becoming the ultimate victor and the sole survivor. At this moment, he is covered in blood from head to toe, both that of Riders and monsters. His entire body radiates an unparalleled, terrifying killing intent and bloodlust. It makes the soul tremble. He also gains all the abilities of the Kamen Riders he has killed. With the abilities of every Kamen Rider combined within him, he becomes the strongest Kamen Rider in the outer reaches of the myriad heavens: the White Tiger, God of Slaughter! Just as he ascends the throne, the world descends into an entirely new one. The information about this world surprises him. It is Douluo Dalu from his previous life! And it's the Tang San era from the first installment! Huang Fei: "Interesting. Riders have arrived in Douluo. Don't fight, and you die!" From this moment on, the story of Douluo will be changed forever! Everyone will live in fear!
