Jiang Lu was no longer the man he used to be.
You see, during his time exploring the Universe with Zeus, they often encountered a language barrier that made normal communication with other tribes impossible, so they had to rely on psychic communication.
This method of communication could only convey information and entirely lacked the art of language.
But when trying to woo girls, such a stiff way of communicating not only failed to yield results but often backfired.
For example, the intended message was, "The moonlight is beautiful tonight; I want to admire the moon with you until tomorrow when we can watch the sunrise together."
But what the alien girl heard was, "I want to reproduce with you."
Crude! Vulgar!
Because of this, Jiang Lu specially learned how to paint from Zeus to convey romance through art.
Greece was already the capital of art, with an influence that even after thousands of years could not be called anything but powerful.
