Immortality begins with upgrading buildings

[Farming/Development] [Ordinary Person Build] [Management/Sales Build]
Ji Yuan transmigrated to a world of cultivation and, although he was lucky enough to become a cultivator, he ended up as a fisherman for a cultivation sect.
Given this start, he originally thought he would most likely only be able to follow the path of "don't underestimate a poor youth, be poor in middle age, and be poor in old age."
Unexpectedly, a building upgrade panel was awakened.
[Fishpond Lv1: Fish fry growth rate +20%, semi-spirit fish have a certain chance to evolve into spirit fish]
[Cave Dwelling Lv1: Self-healing walls, basic dust-repelling barrier, nighttime spiritual energy concentration +20%]
[Chicken Coop lv1: One spirit egg is laid per day, containing trace amounts of spiritual energy, which can be used for fasting]
[Pigpen Lv1: Spirit Pig gains 100 pounds of muscle in seven days; its flesh and blood contain body-tempering medicinal properties and can accelerate wound healing]
[Spirit Field Lv1: Crop cycle -30%, yield contains a trace of wood spirit energy]
【…】
From the most basic [Fish Pond] to the [Alchemy Room] and [Weapon Forging Room] in the cultivation world, all buildings that are based on affinity can be upgraded.
"Cultivating immortality is not about fighting and killing, but about achieving longevity and immortality."
Years later, when the prodigies fell, the holy lands decayed, and the great powers perished, only "Ji Tianzun" became immortal, eternally evergreen.
