This was a connate supreme treasure!
Although Laozi and Yuanshi each possessed one, Tongtian had none. Even though the Four Swords of Zhu Xian were immensely powerful and could form the Zhu Xian Sword Formation, which could not be broken without four Saints, they still could not compare to a connate supreme treasure.
That Tai Cang had actually obtained a connate supreme treasure was simply unbelievable. The three of them could barely process it.
Wait!
Laozi suddenly noticed something and stared fixedly at the longsword in Tai Cang's hand. "This is the Innate Yin Yang Sword!"
"The sword in your hand evolved from the Innate Yin Yang Sword I bestowed upon you back then?"
What? A connate supreme treasure that had evolved?
Yuanshi and Tongtian were even more shocked. After exchanging a glance, they immediately turned to Tai Cang. "Tai Cang, what exactly happened?"
The Innate Yin Yang Sword had merely been a top-grade connate spirit treasure. It should have had no possibility of evolution, so how had it become a connate supreme treasure?
This was simply too inconceivable. A method capable of evolving a top-grade connate spirit treasure into a connate supreme treasure was utterly unheard of.
"First Martial Uncle, Second Martial Uncle, Master!"
Tai Cang respectfully bowed, then raised the Sky-Opening Sword and pointed toward where the Spirit of Heaven Opening was located. "The reason the Innate Yin Yang Sword was able to evolve is because of this object."
"This was also left behind by Pangu's remnant soul, though I brought it out."
Upon hearing this, the expressions of the Three Pure Ones changed drastically, and their gazes all turned toward the place Tai Cang indicated.
Though the Spirit of Heaven Opening had been concealed deeply, it had nowhere to hide before Saints.
"The Spirit of Heaven Opening!"
