Ancient sword formation

This was a stretch of Rolling Stone mountains. All the stones were dark brown in color, as if they were covered with blood.

Moreover, all the stones were covered with shocking scratches, caused by the sword Qi emitted by the sword formation.

As soon as Li Tian got close, he could feel a threatening sword Qi, which made it difficult for him to open his eyes.

"I don't even know how long it has been, but the sword essence of the formation is still so sharp. It seems that this sword formation is extraordinary."

Li Tian's gaze sharpened as he thought about it.

"If I can use this formation, then ... I'll have a trump card in the origin source grounds." Li Tian lowered his head and muttered to himself.

He closed his eyes and began to sense the entire formation.

However, when he released his spiritual sense, the sword array seemed to come to life. Waves of terrifying sword essence were about to pierce through his spiritual sense.

"Ah!"
