The scattered undead they encountered along the way were swiftly cut down and dealt with in no time.
Following behind them, the group proceeded without obstruction.
Before long, they arrived at the center of the Ancient Battlefield, where the passage was located.
Ahead was a cave entrance buried beneath the snow.
Dense footprints surrounded the entrance.
It seemed that quite a few survivors had come here to investigate.
However... there were only footprints leading in, none leading out.
The fate of those people went without saying.
Assam and Broun had already gone over and cleared the passageway.
A spacious tunnel was revealed, roughly five or six meters high.
Cao Xing thought, Good thing this passage is large enough. Otherwise, not only would Big White be unable to enter, but Jode Ironfrost, the newcomer in my territory, wouldn't be able to get in either.
He glanced into the passage, where a faint, miserable green glow emanated from within.
Clearly, there were quite a few undead inside as well.
Cao Xing said, "Assam, Broun, go in first."
"Understood!"
With that, the two of them charged directly into the passage.
Before long, angry roars from the undead and sounds of combat echoed from within.
Cao Xing and the others quickly entered as well.
At a glance, they saw a large number of undead within the passage, frantically attacking Broun and Assam.
Seeing this, Cao Xing thought, There weren't many undead in this passage the last time I came here. There are so many now.
At this rate, it probably won't be long before even more undead rush out of the passage.
When that happens, my territory will likely be the first to suffer.
This also proved that his operation had come at the right time.
Meanwhile.
Assam and Broun were fighting the undead
