It wasn't just Yu Ming who froze when he saw the scene around him. The word "froze" in that sentence didn't even have a literal meaning, but the surrounding lava monsters were frozen for real.
Previously, the lava monsters were fierce and scorching hot, but then they were trapped in a block of ice which automatically stopped their movement. Even their bodies were no longer red after being trapped by the ice blocks. Instead, their color turned blue as they froze in the ice.
Yu Ming froze because he was too shocked by the scene, but he wasn't the only one who couldn't believe what had just happened. Even Hao and the other demons looked shocked, and they could only look at the frozen monsters as the battle finally stopped.
"What's going on here?" Yu Ming asked the question in a whisper, but it seemed like the white-haired woman could hear the whisper.
