Before long, Su Mo found the source of that sound.
He fixed his eyes and saw two martial artists attacking a demonic beast.
There were a man and a woman in their twenties. The man was tall and handsome; the woman looked fair and beautiful, wearing a reddish dress.
To Su Mo's surprise, their cultivation arrived at the Lv 3 True Spirit Realm.
The beast that they were fighting against was a 10-meter-long and Class 4 Lv 3 Demonic Beast Leopard.
Obviously, they had completely lost their offensive stance and could not defeat the beast.
"Ling Ping. We can't win. Go! Go!" The tall young man yelled.
Having said that, they rapidly flew into the sky to escape.
However, the Demonic Leopard moved as fast as lightning. Within a second, it caught up with them and attacked their back with its powerful paw.
"Get away!" The youth angrily shouted out.
