For an advanced martial artist, a toilet is not at all necessary.
Those who have reached the longevity stage or beyond normally have eternal life. Their bodies are free from disease and other issues, and all toxins and waste products cease to exist.
As for expulsion, almost everyone no longer needs it, unless they stubbornly want to maintain their previous living habits and choose to use the bathroom.
But such persistence is a mere formality, after all, martial artists usually spend thousands of years in training. There are few who would still remember something as mundane as using the restroom.
Therefore, toilets have become decorative and lost their original function and meaning.
However, Lin Zhen noticed that the toilet was well-preserved and did not appear to be abandoned. He hesitated for a moment and then walked over.
He entered the men's toilet, which was separated from the women's by a low wall. The wall above seemed to have been destroyed many years ago.
