In the blink of an eye, three quarters of an hour had passed. Hong Feng slammed a heavy palm strike against the formation entrance.
Bang!!!
Under that blow, the formation entrance began to tremble uncontrollably.
Very quickly, a distorted vortex spread across its surface, and the entrance slowly widened bit by bit.
Only after seeing this did Hong Feng speak. "It's ready."
"Very good."
Ximen Tianyang nodded involuntarily.
However, he did not charge in at once. Instead, he waited for the entrance to gradually stabilize.
This disturbance immediately drew Ye Qingtian and the others' attention.
In truth, they had noticed everything the moment the formation began reacting.
Some of those preparing to leave also stopped involuntarily, wanting to know what had happened.
Naturally, Ye Qingtian and the others were among them.
When they saw the entrance slowly appearing, they immediately became alert.
At the same time, a thought arose uncontrollably in their minds.
Could Xuanyuan Haoyu and the others have returned?
Aside from that possibility, they could think of no other explanation.
"Isn't this rather strange?"
Ye Qingtian took a deep breath and spoke.
Ji Yaoyao nodded. "Could they have left something behind?"
"Do you think that's likely?" Ye Qingtian asked.
Ji Yaoyao fell silent. Only after a while did she say, "It has only been three quarters of an hour from start to finish. Only someone familiar with the method of breaking the formation could open it."
"So, apart from the one who set up the formation, do you think there could be any other possibility?"
This time, it was Ye Qingtian's turn to fall silent, because that was indeed the truth and fit the basic logic of the matter.
But Ye Qingtian soon grew tense again. "I still feel uneasy. We should have our people be more careful."
