Qin Wentian naturally didn't know of what the others were thinking. Right now, he was fully immersed in this world before his eyes. There were boundless lines formed from law, interweaving into runes of the Great Dao.
Every rune of law was of a different kind of energy, and manifested different types of innate techniques. These, were the daos of heaven and earth.
The dao of runes originated from here. When in his particle world, Qin Wentian had once researched and analysed divine inscriptions. At that time, he already sensed that there was a connection between divine inscriptions and innate techniques. All sorts of techniques were linked at the base, when one grows closer and closer to the intrinsic quality, they would discover how marvelous that was.
With regards to immortal and devil, there was originally no difference. For this point, Qin Wentian was already very clear during the test he experienced when he ascended the Devil Mountain.
