From a family fisherman to a water immortal

Li Quanqing traveled through the world of immortal cultivation and became a family fisherman. He started with a 20-acre fish pond.
Unexpectedly, every time he harvested spiritual fish, he could get a light ball reward.
[Harvest an adult big black carp, reward a low-grade water arrow talisman! ]
[Harvest an adult iron-bone crab, reward "Gengjin Sword Art"! ]
[Harvest an adult longevity turtle, reward turtle longevity pill, extend life by 20 years! ]
…
From then on, Li Quanqing watched the ups and downs of the world, the changing situation, and just wanted to raise fish and become an immortal.
Until thousands of years later, a certain water-virtuous immortal came out of nowhere, shook the immortal realm, and covered the sky with one hand.
"Since the Milky Way is also a river, it's okay for me to use it to raise fish, right?"
