Classic of Mountains and Seas Once Every Ten Days, My Background Is China

[The only double entrance door at the beginning] + [The whole nation serves as the background] + [Modern technology VS ancient mythology] + [Survival and exploration infrastructure flow] Chen Fan, an ordinary person, suddenly awakened a mysterious ability one day: he would travel to the Classic of Mountains and Seas at a fixed time every ten days. The first time he traveled through time, he encountered the dangerous white-haired unicorn. His right hand was fractured and he almost died of starvation. At that moment, he understood something. It's too dangerous to play in another world alone, you have to find someone to help you with! "Thighs? Can they be thicker than the country's father?" So, he resolutely chose to cooperate with China! From that day on, the whole of China moved for him. The world, which was originally full of crises, has become safer little by little with the help of the country. In the exploration again and again, China's technology tree is also lit up little by little. The Swift Type I and Juli Type I genetic medicines were launched accordingly... Psychic army-breaking series of weapons were successfully developed... The psychic revolution begins... The scene of all nations coming to court reappears... Iron Man, the Wanderer's mecha was created... When he thought everything was going well. All kinds of more problems are coming—— ​​​​​​​​​​​​​​​​​​​ Forced to get involved in a mythical tribal hegemony? The battle between immortals and gods? Chen Fan: You dare to use me as a chess piece? If I don't kill you, I will be your grandson! "Bring me the 99th generation psychic rail gun!" "Today, I will bombard Kunlun!!!"
