Three years ago, a mysterious oppressive force suddenly emerged. Although elusive, with Ao Qianchi's stature as an Immortal Emperor, he naturally sensed it.
Li Cheng and Immortal Emperor Tianyuan sensed it as well, but to their surprise, Ao Qianchi had researched for three years with no progress.
"Brother Ao, how is the one suppressed inside?" Immortal Emperor Tianyuan asked.
"Do you suspect he's behind this? No, he remains as before, only able to slowly release a wisp of deathly aura," Ao Qianchi shook his head.
Immortal Emperor Tianyuan pondered, "Then it's strange, could it be a method left by Blunt Empty Venerable that's been activated?"
Ao Qianchi nodded, "I've suspected that as well, but I've searched every inch of the city and found nothing."
Speaking of Blunt Empty Venerable, Li Cheng's eyes lit up. He had a brief exchange with the Venerable three years ago, but it seemed as if the Venerable had perceived some crisis and thus immediately cut off the exchange.
