Changsheng: I Have a Building Upgrade System

Gao Yuan traveled through the world of cultivating immortals and discovered that although the original owner was lucky enough to become an immortal cultivator, he was actually destined to work as a farm slave for the sect. The rent is 15 yuan of spiritual stones a year, and the whole body is only 7 yuan. How to get the 8 yuan difference? With this start, it would be a good thing if he didn't get kicked out of the Qingtian Sect. But he never thought that he would accidentally awaken a building upgrade system. [Spiritual Field lv.1: Planting speed +20%, spiritual plants have a certain probability of evolving. [Cave lv1: Spiritual energy gathering speed +20%, there is a certain probability of enlightenment when the cultivation level breaks through. [Alchemy Room lv1: The probability of furnace explosion is -30%, and the output has a probability of increasing. …… From the most basic [Spirit Field] to the inner door [Alchemy Room] and [Item Refining Room], as long as they are tall buildings, they can all be upgraded. A few years later, when all the geniuses came to an end, the sect collapsed, and the immortals fell, only "Gao Tianzun" could pick up the stars and remain immortal forever. "People ask me why all the time." "As everyone knows, your results are based on luck and are hit and miss." "And I relied on upgrading the system to form an assembly line production step by step!"
