After the Nuclear Wasteland, I Planted Missiles in the Strange Garden

Nuclear war breaks out and radioactive beasts are rampant. After the practitioners saved the world, they established a new order. Cities with cultivation as their core were born. Humanity has learned its lesson, advocates the supremacy of cultivating immortals, and resists technology. Chris, who was in the city, was unable to practice. But he has an exotic garden where he grows all kinds of chatty plants. It is good to cultivate immortality and live forever, but it is also good to build a country through science and technology.
