Yam and Fei Charlie each led several team members, alternating between covering attacks and retreating.
Although their attacks could not damage the Metal Monsters, they could still delay their movements somewhat, allowing the two teams to widen the distance between themselves and the Metal Monsters.
At this point, the Metal Monsters had split into two groups, and the Ability Users could not retreat along the Great Hall's main passage. The distance there was simply too short—just over two hundred meters.
So the Ability Users moved laterally through the Great Hall, naturally using the Stone Pillars as cover as they retreated.
It was this lateral retreat that caused the Metal Monsters to split into two groups: one group attacked the mercenaries, while the other followed behind the Ability Users.
It was now Fei Charlie's turn to lead his team members in attacking the Metal Monsters.
At that moment, Fei Charlie saw one monster pause briefly due to an ability attack, only for the monsters behind it to crash directly into it. An idea immediately came to him.
When faced with walls and similar barriers created by abilities, the Metal Monsters simply smashed through them. They never tried to go around the walls formed by ability releases.
So, after a series of ability attacks at regular intervals, he led his Ability Users back while speaking to Yam over the radio. "Yam, I had my men put up a barrier just now, but these Metal Monsters just charge through it instead of going around. So if we set up an obstacle at the height of a tripwire, could we trip them and buy ourselves more time?"
The moment Yam heard Fei Charlie's suggestion, he felt it was worth trying. He immediately agreed and prepared to test it.
In ancient times, tripwires were used
