Drums!
Gradually the entire situation here changed and became the focus of the enemy troops in this region. The enemy troops weren't in good formation at first, but after an hour, they started to form themselves and lined up, coming at me in a more organised fashion.
The counter move I used was to increase the amount of energy I sucked and directed towards my tripod artefact. The increased energy helped in relieving lots of pressure over my side, and even when the enemy came prepared, they couldn't achieve anything worth mentioning.
On the contrary, when my forces absorbed the shock of the enemy's arrival and stood their ground firmly, they started to push the enemy backwards, killing lots of them at fast speed.
This took almost five hours to happen, and then the enemy started to witness what could be best described as their nightmare.
[I cleared my zone] and just after a couple hours, I got such a message first from Sara.
