The Classic of Mountains and Seas Every Ten Days, with China as My Backer

[The Only Transmigration Gate from the Start] + [The Entire Nation at His Back] + [Modern Technology VS Ancient Mythology] + [Survival, Exploration, and Construction] Chen Fan is an ordinary man who suddenly awakens a mysterious ability one day: every ten days, he transmigrates to the Classic of Mountains and Seas at a fixed time and place. On his first trip, he encounters a ferocious white-haired Xingxing, breaks his right arm, and nearly starves to death. In that moment, he understands one thing. Exploring another world alone is too dangerous. He needs a powerful backer! “A powerful backer? Could anyone be more powerful than the nation?” So he resolutely chooses to work with China! From that day on, all of China mobilizes for him. With the nation's help, a world once full of dangers gradually becomes safer. With every new exploration, China's technological tree lights up bit by bit. The Swift-I and Might-I gene serums are developed... The Spirit-Energy Po Jun weapons series is completed... The Spirit-Energy Revolution begins... The nations once again come to pay tribute... Iron Man and Jaeger mechs are built... Just as he thinks everything is flourishing, however, all sorts of new problems come swarming in: AI becoming sentient? Being dragged into a struggle for supremacy among mythological tribes? A war between immortals and gods? Chen Fan: “You think you can use me as a pawn? If I don't crush you, I'll be your grandson!” “Bring me my ninety-ninth-generation spirit-energy railgun!” “Today, I'm shelling Kunlun!!!”
