My Family's Forest Farm Connects to the Cretaceous, and I Hand It Over to the State from the Start

[Prehistoric Beasts] [Specialized Dragon Hunting] [Hardcore Research] [Expeditions Into the Ancient Past] Lu Yan, a veteran who left the army, is patrolling the mountains for strange bloodstains when he unexpectedly steps through a crevice deep in a forest reserve and into the Cretaceous period, a hundred million years in the past! Faced with primeval forests that blot out the sky and vicious raptors closing in from every direction, Lu Yan levels his double-barreled shotgun, blasts the prehistoric killers at close range, grabs a nest of dinosaur eggs, and promptly returns to the present. Confronted with a discovery that could overturn the science of human life, Lu Yan doesn't keep it to himself. He reports directly to the government's top scientific research and advanced security task force: "Report: I killed a living dinosaur. The crevice deep in the ravine behind the mountain... connects to the entire Cretaceous period!" The top-secret project [Codename: Prehistoric Hunt] is fully launched! The passage is governed by the strict [Seven-Day Material Cycle]: on Mondays, only metal can pass through; on Wednesdays, only living organic matter... Since they can't build large settlements on the ground, they will turn the Cretaceous into a premier resource hub and genetic hunting ground! The specially recruited guide Lu Yan, a field sniper, an anesthesiology expert, and a paleontologist form the [Deep Time Special Operations Hunting Team]. Lure intelligent Troodons into a trap to decode their genetic maps, strip ankylosaur armor for research into biological composite armor, and capture adult tyrannosaurs with long-range anesthetics! From this day on, the prehistoric overlords from eighty million years ago face a crushingly one-sided hunt at the hands of a modern industrial and technological team!
