Good grief, the son of the ancient demon god, both of his parents are Tao Venerables, and he even practiced under Donghuang Taiyi. His origins are indeed not insignificant.
But Jiang Chen paid no attention to these things. His attention was caught by Canglang's statement that Wu Huai had tens of thousands of years of cultivation.
The existing martial Dao was born after the Three Sovereigns and Five Emperors. Meaning, what Wu Huai practised was the Ancient Martial Arts, rumored that no one could survive for ten thousand years.
Yet, according to what Canglang said, Wu Huai had not just survived ten thousand years, but even several tens of thousands of years.
Having survived tens of thousands of years by practicing Ancient Martial Arts, this indicates that the strength of Wu Huai must have entered the Tao Venerable Realm.
