Xiuxian Baiyi System, I know everything

Traveling through the world of immortal cultivation, he became a low-level casual cultivator. His predecessor was attacked and did not wake up for three months. He occupied the nest of a magpie. Just when he was about to be driven out of the market because he could not renew the lease, the Immortal Cultivation Hundred Arts System appeared!
I can do what you can do, and you can't do it. Sorry, I still can do it. In short, I can do it all.
From then on, the protagonist began his counterattack life and finally walked out of the road of longevity.
The protagonist will live in the market in the early stage, and later he will bring his Taoist partner and children to establish a family and become the founder.
In short, this is the creation process of an immortal family from scratch. The story is very long, so please read it slowly!
