Gu Zhan furrowed his brows and said, "Is it really like this?"
Gai Qingcheng slowly said, "If you look through historical texts, even if you completely wear them out, there are many things for which no trace can be found. As of now, the historical record with specific documentation can be traced back ten thousand years.
Martial Arts only began to appear three thousand years ago, and in the seven thousand years between ten thousand and three thousand years ago, there are no records of cultivation. However, there are some traces, and it is these traces that later became the Grotto Heaven Technique. It was after these traces were discovered that the Grotto Heaven Realm's Land Immortals were achieved."
Gu Zhan slowly asked, "Is that how the Gu Family came to be?"
