It was as if, without the Inner Heaven and Earth, he devised a Cultivation Technique suitable for it out of thin air.
Actually, it was not that difficult originally.
Because, even if one couldn't create it themselves, they could rely on the experiences of predecessors.
For example, the Demon Clan, which possessed a Cultivation Technique from their inherited bloodline, didn't need to worry about this.
For example, the Duke Heng's bloodline was the same.
Even if others couldn't, they could still find predecessors and ancestors who had mastered the same path, having a reference in Cultivation Technique of the same path, making it not that difficult to create on their own.
For example, the Taiyin Path, surely there were predecessors who, with the Saint Heart Dao Union, developed an Inner Heaven and Earth centered on the Taiyin Path, and then used the Power of Taiyin to create a suitable Cultivation Technique, which was much simpler than creating from thin air.
