"Thud."
At the back mountain, at the same time, there seemed to be a sound of something heavy hitting the ground.
In Bai Xiao's hand, however, there appeared a dark core resembling a mechanical heart, with metal frantically writhing and clenching, continuously operating. A mysterious power fluctuation reached directly into the void depths, as if extracting endless energy.
"Is this a void engine?"
Bai Tang immediately recognized it and couldn't help but speak.
"Yes, I killed another one."
Bai Xiao wore a faint smile on his face, his voice calm.
Bai Tang was shocked again by these words. Just now, her brother had killed a flying level to save her, and half an hour ago his avatar held the rear, and he had killed yet another flying level! Existence at the flying level is not as common as cabbage, easy to take down. It shows Bai Xiao's power is mysterious and terrifying to the extreme.
"Brother, how did you..."
Bai Tang hesitated for a moment, but couldn't help asking.
