Hundreds of thousands of years ago, there was a glorious civilization created by telekinesis on Earth. But the peaceful life will eventually come to an end, and a will aimed at destruction and death is about to come to the earth. They are called by ancient people as "the Luohou Gods who come from the other side of Earthly Evil {the position of "big evil" in Feng Shui orientation}". In order to fight against the fate of destruction, ancient people began to build "super robots", weapons of ancient civilization, and this war was also called the "robot war". All kinds of super robots also have levels. The familiar "Strongest Dragon" Dragon King Machine and "Invincible Tiger" King Tiger Machine belong to the second stage "Four Gods". In the battle with the enemy super robots "Four Evils" and "Four Sins", the Dragon and Tiger machines betrayed their master for some reasons that are still unknown, and knocked down the Bird King Machine and the Four God Machines. King Wu took the opportunity to escape. In the Spring and Autumn Period, famous craftsmen Lu Ban and Mozi discovered the sleeping dragon and tiger machines, and modified them, giving them the ability to combine. At the same time, metal, wood, water, fire and earth were also installed for the second machine. The five elements of heaven and earth serve as the perpetual motion mechanism "Five Elements Wheel". But the Dragon Tiger II also has its own will and will choose its own driver, which is very similar to the Magic God of Machines. Time passed, and at the end of the 19th century, the Dragon and Tiger King awakened again. Under the control of the Japanese young man Inaka Takauma who claims to "not belong to this era" and the descendant of the guardian of Chiyu Tomb, the Chinese girl Wen Li fights against the "Hundred Evils", a group of super robots. Standing in front of it at this time was the "King Quewu" who had been its enemy for tens of thousands of years. As its name suggests, Quewuwang is a combination of Quewangji and Wuwangji. Among them, Quewangji pursues extreme attack power, while Wuwangji pursues high defense power. Although King Quewu is controlled by the British officer Grimz, it is believed that it is his own wish to be able to show off with the Dragon and Tiger King. Spanning tens of thousands of years, the Dragon Tiger King and the Quewu King launched a peak showdown of "Dragon King's Mountain-Breaking Sword·Reverse Scale Sword VS Black Snake Sword·Five Elements Fierce Slash". . . . . . . And above the Dragon and Tiger King, there is also the most powerful super robot "Four Spirit Kings" who stand at the apex of the super robot legion. Among them, Yinglong, known as the True Dragon King Machine, is usually sealed under the Great Wall. The seal will only be released when the "Tiangu" phenomenon occurs. Yinglong, who could not tolerate the betrayal of the Dragon and Tiger King, also woke up and started an earth-shattering battle with the Dragon and Tiger King. . . . . . In the New Western Era, the super-archaeological agency LTR excavated the Dragon and Tiger machines in the Chiyou Tomb in Shandong, China. However, the DC officer Archibald Grimson (the descendant of King Qiaowu pilot Grimz) led his troops to attack the excavation site out of his persistence in family history. This time, the person piloting the Dragon-Tiger aircraft in the battle was Federation Army pilot Mizuha Nan Yehbritt. "I am the Enraged Super Robot, the invincible Blue Dragon Tiger King!" "I am the Roaring Super Robot, the strongest White Tiger Dragon King!" The Dragon and Tiger machines, which absorbed the three parts of Gurungast, merged into one. After that, members of the SRX project added T-LINK system, telekinesis field and other auxiliary systems to it, creating the most powerful protagonist machine in the history of machine combat. After the war, the traces of the Dragon and Tiger King also disappeared from Nanye. Until one day, Dragon King Ji appeared in front of Nan Ye with scars all over his body. What chases it is the dark King Tiger machine, and the pilot is the brainwashed Britt. The gentle Nanye took the Dragon King machine back for repairs. In order to save its life, the mass-produced Gurungast II had to be installed on the Dragon King machine, forming a new humanoid weapon "Dragon Man Machine". Because he misses his companion King Tiger, parts of the Dragon's originally blue armor turned white. The person who controls the Dark Tiger Machine is the mechanical god "Steel Eden" created by the ancient people. This supercomputer, which was originally born to protect the earth, went awry and believed that in order to protect human beings in a crisis-ridden universe, the earth must be completely wrapped up, and no outsiders are allowed to enter and no earthlings are allowed to go out - just like a mother who overprotects her children. Same. In order to put the two swords Dragon King Ji and Tiger King Ji back into his scabbard, he would not hesitate to destroy the Dragon King Ji. Although her intentions were good, this behavior was clearly unacceptable. The people of Earth began to resist Steel Eden.
During the battle, Nanye and Dragon King Ji awakened the closed hearts of Britt and Tiger King Ji, so: "The God of Fire! The devil surrenders! The dragon and tiger merge!" The Dragon and Tiger King once again merged into one and once again used their invincible power to fight. The power of overlord stands on the earth. At the end of the war, in order to save the girl Ilui who was possessed by Steel Eden, the Dragon Tiger King sent Nanye Hebrit out of the body at the moment when Steel Eden was about to explode, but he disappeared in the flash of light. . . . . .
