There Is a World Beyond the Earth

On the most unlucky day of Lynch's life, his drone lost contact on the mountain. He climbed up the mountain to look for it, but the GPS failed and the compass spun randomly, and then—— He fell into a dimension that didn't exist. The gray-brown sky, two blood-red moons, and a group of aliens as thin as skeletons were surrounding him, muttering in a language he couldn't understand. A voice suddenly sounded in his head: [Mission: Survive within 72 hours. Reward: 500 civilization points. Failure: Erase memory and return to original life trajectory. Lynch looked at the three hundred and eighty-seven yuan left in his pocket, and then at the group of starving aliens in front of him. "Return to the original life?" He smiled, "Then let me die here." Three days later, he built a wall for the aliens using stones and wood. Three months later, he returned with an entire country's engineering team. [No harem + hard-core infrastructure + rise of national destiny + collision of civilizations] "There are worlds beyond the earth. And those worlds need someone who can build walls."
