I Asked You to Build a High-Speed Rail, but You Actually Built a Portal?

Traveling to a parallel world, it happened that the country was developing high-speed rail. Zhou Yuan took the initiative to ask for the job! A month later, there was no high-speed rail, but the portal was born! "It's fake, this must be an illusion created by the Great Dragon Kingdom!" "Build two mirrors and call them portals, true or false!" "This kind of technology is not even available in the Mei Country, and it is impossible for the Dragon Country to have it!" While foreign countries were criticizing fraud, Zhou Yuan was doing ruthless things one after another. A super-light flying sword, a three-purpose Xuanwu aircraft carrier, and a defensive array that even nuclear bombs cannot penetrate. What's even more outrageous is that Zhou Yuan also founded the Academy of Immortal Cultivation, where everyone lives a hundred years and flies to heaven and earth. Japanese: From now on I will never be a dog of the Mei Kingdom, I will be a dog of the Dragon Kingdom. Mao Xiong: From now on, I will be the loyal number one brother of Dragon Kingdom. Mei Kingdom: It's over, the Dragon Kingdom is invincible... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
