In place of the intruder team.
The night went according to what the two of them had planned, the team of intruders had arrived at the place of the thugs they had met at the bar earlier. They were in the right position to see the movements of the thugs. That night was the night of the transaction between the thugs and the underground super market liquid seller. Their meeting place was in one corner of the building which was quite dark, maybe it was the territory held by the thugs.
The intruder team is very carefully snooping around with full weaponry, they both plan to get hold of the liquid to prove if it's real or fake. According to the information they had previously obtained, the liquid was extremely difficult to obtain, perhaps it was an opportunity to obtain the liquid.
