The GRU operatives outside the door were definitely not amateurs. Though Song Heping managed to kill three, they still maintained a considerable degree of composure—two by the door kept up suppressive fire, while two rushed in and quickly dragged the injured out.
Almost simultaneously, a GRU agent threw two tear gas canisters into the room.
Their coordination was fluid, and their crisis response was rapid.
The irritating gas quickly released from the canisters.
Song Heping hurriedly signaled to Utekin in the small room opposite, indicating that he had to evacuate immediately.
It was evident that the GRU outside would hold the door, then wait for the gas to fill the entire room before storming in with the help of the tear gas.
This was almost a standard procedure, tried and true.
"Jiang Feng, how's the situation downstairs?"
Song Heping estimated the time, believing Jiang Feng should have already retreated downstairs through the secret passage.
