The moment the four Top-grade Innate Spirit Swords appeared, a heaven-shaking killing intent centered on Qingfeng swept in all directions.
"Top-grade Innate Spiritual Treasure?"
At this, Shi Zhou Shan immediately grew wary. Even Huiyang beside him looked as if he were facing a great enemy.
In the end, one of them had emerged late, while the other was shallow in strength and limited in knowledge. Neither recognized the Four Immortal Slaying Swords right away.
The moment Qingfeng revealed the Four Immortal Slaying Swords, Guang Chengzi's expression in the distance changed drastically. He instantly recognized what Qingfeng was holding.
He hurriedly shouted a warning to Shi Zhou Shan, the state ruler.
"Be careful! The sword in Qingfeng's hand is the Immortal Slaying Sword."
The Immortal Slaying Sword? Who cared what sword it was?
Shi Zhou Shan did not believe that four Top-grade Innate Spirit Swords could break through the two Defensive Spirit Treasures on his body in a single strike.
As long as he was given several breaths of time to completely take control of the Army Formation's power from the Buzhou Immortal Army,
even if Qingfeng possessed an Innate Supreme Treasure, he would still be unable to escape suppression in this battle.
However, in the instant Shi Zhou Shan was stunned, he suddenly remembered what the Immortal Slaying Sword was.
"The Four Immortal Slaying Swords!"
This time, a trace of fear appeared on Shi Zhou Shan's face.
According to legend, when these four swords were combined, they truly possessed might on par with an Innate Supreme Treasure.
The two Top-grade Defensive Spirit Treasures on his body might not be able to protect him.
After figuring out what the Four Immortal Slaying Swords were, Shi Zhou Shan immediately wanted to flee, putting as much distance between himself and Qingfeng as possible.
