He had long known that Tang Feng's Xuanyuan sword Sutra was taught by the little human King.
A copy was carved by someone, so it was not as effective and fast as the original. It lacked the original Dao runes.
However, he could still comprehend it if he spent more time.
Right now, he was lacking offensive immortal Scriptures and immortal techniques.
He now had three complete immortal Sutras, namely the undying immortal Sutras, the ten thousand universe void Sutras, and the ten thousand Dao immortal Sutras.
Only the 'myriad DAOs immortal Sutra' was an attack-type.
However, the immortal Sutra of myriad DAOs was a bit special. One needed to comprehend the rules of immortal techniques first before they could steal and integrate other attack-type immortal Sutras.
If there were no other offensive immortal Scriptures, the myriad DAOs immortal Sutra would lose its effect.
The Xuanyuan sword Sutra was just right.
