Doomsday: Start a Technological Fortress

Three years ago, a mysterious system bound Shen Chao and told him that he was the savior and was about to travel through a parallel doomsday world. Three years later, Shen Chao arrived, and the system directly presented him with a technological fortress. Staying in the fortress, every unlocked facility can be continuously upgraded! However, a few days later, Tu Qiong was seen. Unexpectedly, he was playing with fear of death! The system had been with him for three years and watched him acquire various professional knowledge in agriculture, first aid, breeding, firearms, missile production, etc. It thought he was going to adopt a reckless style of play, so it recommended a special plan to him. The system asked him to unlock the 3D weapon printing platform, and he unlocked the livestock area and started raising pigs. The system asked him to unlock the technological equipment platform, and he unlocked the land for farming day and night in the agricultural area. There is no way, a single-minded system is dead, but people are alive. You have your plan, and I have mine! It is impossible to be reckless, and it is impossible to be reckless in this life. Only by living hard can we maintain our lives. Until Shen Chaogou arrived at the mountain of supplies, he had no worries about food and clothing, hundreds of guns, millions of rounds of ammunition, and even mastered various powerful powers. He is still struggling! "Isn't there a storm today? I won't go out." "Oh, there are zombies outside the door. Go and clean them up right away. I'll finish the roasted lamb chops first." "This is called obscene growth. If you let me grow for another two or three months, I will definitely save the world." "Don't push me, don't you still believe me?"
