Immortal Cultivation Family's Farming Longevity

[No system, no harem, genius flow, slow heat, time travel, traditional fantasy] The imperial court is weak, the sects and aristocratic families are running rampant, the Dan Kingdom's world of immortality has ushered in a great breakthrough, and even the demon kingdom that does not belong to the human race has to retreat. The Li family has been inherited for more than 200 years and has become a Zifu family. Although they started with spiritual plants, they are not just farming! I have seen the Li family open up wasteland everywhere and step by step towards the top of the world. The protagonist has two spiritual roots (comparable to a single spiritual root), and can be used both behind the scenes and in front of the stage, and multiple forces compete for hegemony. Plenty of ideas, listen to advice, the pace is a little slow in the early stages.
