Cultivating Immortality: I Have a High-Martial World

[High-level martial arts and immortal cultivation dual transmigration + reporting to the country at the start + farming and management style]
"Mr. Lin Chen, I've heard you have a well-known secret: every seven days, you travel to the cultivation world, and then seven days later, you travel back from there?"
"That's right, and what's even more amazing is... after I traveled to that other world, time was frozen!"
"So, Mr. Lin Chen... possessing such a huge secret, why did you choose to report it to the country in the first place?"
"Nonsense! If I hadn't reported it, would I have achieved what I have today?" said Lin Chen, the martial god of this era, the only immortal among all living beings, and the person in charge of both realms.
