My System Always Delivers Benefits in Troubled Times

Lu Ming, a social animal, traveled to an ancient and troubled world where life was like grass. Both his parents died, and he only had a silly younger brother with an amazing appetite and the ability to carry a cauldron. It is bound to an unreliable [Civilization Reconstruction System], but the tasks issued are always outrageous with a hint of reasonableness: "Please take in ten refugees (reward: potato seeds)", "Please build a public toilet (reward: simple cement formula)"... In order to survive, Lu Ming could only hide in the mountains with his younger brother and a group of old, weak, sick and disabled. Others build cottages for the purpose of robbing families and homes, but he built cottages for the purpose of construction, land reclamation, farming, and sanitation. When the cottage was full of grain, the houses were sturdy, and everyone had clothes to wear, Lu Ming realized that he, the "king of the mountain," seemed to be acting a little differently. Until the world was in chaos and the princes rose up together, he looked at the tragic situation of people starving and dying at the foot of the mountain, and then looked at the "shanzhai Special Zone" behind him where he lived and worked in peace and contentment, as well as the flashing new task line in the system—— "The ultimate mission is released: end the chaos and establish a new order. Reward: Ticket to return home (optional)." Lu Ming was silent. Go home, or build a "home" for this era and for everyone who follows him, where he can never look back?
