Yun Tianxia's Great Destruction Formation was hidden under the sinister and dark Yellow Fountain River. If the people who entered didn't pay attention to it, they definitely wouldn't be able to notice.
Did Jin Yu and the others pay attention?
No!
Their goal was always Yun Tianxia. All of their attention was attracted by all of them.
They didn't even notice when the Great Destruction Formation was activated. until it exploded did they look around in terror.
"We fell for his trap." Jin Yu's expression changed. A cold glow flashed in her eyes as she stared at Yun Tianxia coldly.
"Let's go!" The butler's first reaction was to retreat.
But Jin Yu charged instead of retreating. She scolded, "Why are you running? Kill Yun Tianxia. Without someone activating this formation, how strong can it be?"
Jin Yu was really decisive and charged. Even if she was badly injured, she wanted to kill Yun Tianxia.
