Yang Luo also realized it.
This old madman, though a bit crazy and impetuous, with a resolute and ruthless temperament, was indeed a martial arts fanatic.
To learn the upper part, he was even willing to kneel before himself.
If this were to get out, it's likely that all the cultivators from Kunlun Ruins and Penglai Immortal Island would be shocked speechless.
How esteemed is a Heavenly Immortal?
Adored and worshipped by Ten Thousand Immortals, bowing their heads in submission!
Moreover, this old madman is at the Heavenly Immortal Perfected Stage, on the verge of stepping into the Golden Immortal realm, crushing the Void, and ascending to the Upper World!
"You can rest easy now, I definitely won't trouble you all anymore!"
Gu Tianshang burst into laughter, then said: "However, since you are willing to teach me the upper part, then you are my master!
Of course, you must also acknowledge me as your master, and I'll teach you the lower part!"
