Taishang Laozi was still furious, but a trace of uncertainty remained in his eyes.
In his recent battle with Lin Xuan, the One Qi Transforms into Three Pure Ones technique he had placed such high hopes in had been defeated.
It had been completely unable to break through the Immortal Slaying Sword Formation Lin Xuan had set up.
Not to mention injure Lin Xuan, who was protected by the Chaos Bell and Pangu Banner, both Innate Supreme Treasures.
If he had not been protected by the Taiji Golden Bridge formed from the Taiji Diagram and the Heaven and Earth Mysterious Yellow Exquisite Pagoda, he would probably have already been wounded by Lin Xuan's Immortal Slaying Sword and God-Slaying Spear.
This shouldn't be possible!
The more Taishang Laozi thought about it, the darker his expression became.
He was confident that even the Immortal Slaying Sword Formation personally established by Sect Master Tongtian could be broken by his One Qi Transforms into Three Pure Ones technique.
But why?
Primordial Heavenly Venerate's Evil Corpse Incarnation had already determined that Lin Xuan primarily cultivated the Law of Death.
So why was he also so proficient in the Sword Dao Law?
His Immortal Slaying Sword Formation was even stronger than Tongtian's, despite Tongtian having controlled it for countless ages!
This made no sense!!!
At that thought, a guess suddenly flashed through Taishang Laozi's mind.
Unless...
Lin Xuan possessed a Supreme Treasure capable of helping him comprehend the Dao!
Only then could he possibly be so proficient in both the Sword Dao Law and the Law of Death.
It would also explain how he had refined Primordial Heavenly Venerate's Chaos Banner so quickly.
After thinking of this possibility, a terrifying glint immediately flashed through Taishang Laozi's eyes.
A Supreme Treasure capable of helping a Saint-level existence
