Crossing two worlds + two people traveling together + the strongest backend + resource development + the whole country soaring At the beginning, I handed over to the world of cultivating immortals... And my brother? His brother Fang Ping died in a car accident. On the first seven nights, Fang Yuan received his cross-border request for help! "Fang Yuan! I traveled through time! I was about to die as soon as I entered the Demon Sect! Save me!" The fate lock in Fang Yuan's hand became the only channel connecting the two worlds. In order to save his brother, he took the risk and handed over the magic stone passed back by his brother to the country. As a result, the country's top officials were alarmed, and Unit 749 came to the door! "Anyone who dares to harm our Chinese people will be punished no matter how far away!" "Comrade Fang Yuan, let's find a solution on your brother's side. You! You are our first pioneer in cultivating immortals!" "What? Not enough spirit stones? No money to buy a cave?" "Transfer a small target from the treasury!" "What? No experience in dual cultivation with a female devil?" "Immediately summon the ambassador of the island country and package and send the teachers' latest learning materials!" ""Five Yang Burning Heaven Jue"? Simple! Let AI translate it for you, even elementary school students can understand it!" ""Ten Thousand Swords Return to the Sect"? Simple! Isn't it just a swarm of drones in the shape of flying swords?" From then on, Fang Yuan became the country's most precious guinea pig. My brother passed back the incomplete elixir recipe, and the country used a supercomputer to complete it. Fang Yuan took it first! He picked up a rubbish magic weapon, and the country used nanotechnology to transform it, and Fang Yuan used it first! My brother is still fighting a battle of wits and courage with a group of old men in the Demon Sect, and I am already relying on "our mother's" black technology to prepare to build a foundation! With the efforts of the two brothers, the entire Dragon Kingdom gradually embarked on the path of universal cultivation of immortality. Until one day. "Report, brother! I'm here to take you home! By the way, our mother asked me to ask, can they contract for the infrastructure of this world?"
