The team that stayed included a few members who were good at explosives. Their mission was to detonate the armory.
In the end, Piggy Liang chose to detonate the armory by remote control because the timing of the detonation was not easy to choose.
When Kronin discovered that the stronghold had gone missing, he would definitely realize that the stronghold had been attacked and would immediately send a combat team to check the situation.
The number of this combat team would not be too small, because if they were too small, they might be ambushed.
If they could not rescue them, they would lose their men for nothing.
Therefore, the team that returned to the base to scout and rescue should have at least 100 people, with a certain size.
In order to ensure that as many as possible could kill the enemy, the timing of the explosion of the armory was very important.
