My spiritual energy revived, I started cultivating immortality from farming

Description

Others travel through time and practice cultivation, and their golden fingers hang on to the end;
Jiang Tang traveled through time to cultivate himself, and was so slapped in the face by reality that he became autistic.
After three years of farming honestly, Jiang Tang suddenly found that he had an extra space in the spiritual field. The spiritual field actually grew rare spiritual herbs, elixirs, martial arts secrets, and even treasures that disappeared from ancient times!
So Jiang Tang also had his own golden finger.
Many years later, Jiang Tang, who accidentally turned himself into an all-around master, was promoted to the next level. He burst into tears and said——
"Since time travel, don't deceive me, Goldfinger Jiraiya."
