God rewards hard work: Farming and cultivating immortality

[System + Farming + Taming Beasts + Slow Heat + Daily Life + Upgrade]
An ordinary baby boy was born in an ordinary rural area.
With a loud cry.
"Ding, activate the [Learning] skill!"
Just like that, Jiang Lan traveled through time, taking the skill system with him.
As long as you do things that match the skill description, you can continuously increase your experience. When you have enough experience, you can upgrade and get branch abilities.
[Learning] can gain understanding
[Teaching] can impart skills
[Farming] can increase crop harvests and strengthen crop abilities
In the future, you will be proficient in formations, alchemy, talismans, taming beasts, and farming.
Let's see how a mortal relies on his liver to achieve immortality and roam freely between heaven and earth!
