It must be known that burrowing was their innate talent. When they burrowed, they also depended on the situation on the ground. If it was an ordinary ground, then their burrowing speed would naturally be faster. If it was a stone ground, their burrowing speed would be slower.
Now, their speed was obviously slower than before. Of course, it didn't matter if they were slow. If they really encountered a ground full of stones, it was normal for them to be slow. But what surprised them was that the soil in front of them was obviously ordinary soil, which was strange.
The team leader immediately noticed this unusual situation. He realized that they had triggered the enemy's formation. The enemy's formation had been activated. This was because they were from the race of the hollow rats and had the innate ability to divide the soil. Otherwise, they would have been trapped here and even crushed to death by the surrounding soil.
