Actually, even if this person didn't surrender, Dark Square had never planned to kill him directly.
Because Dark Square hadn't forgotten... the real main mission was "to take back Annan's token."
This step was merely to acquire weapons and gather the next piece of intelligence.
After all, Dark Square was entirely unfamiliar with the environment here—he didn't even know the local customs or the distribution of power within the city, let alone how many enemies there were. He only knew two things... his equipment was at Xiushui Street No. 23, and the mission target was at Xiushui Street No. 35.
Dark Square certainly didn't want to kick door in only to find over twenty people inside, staring back in confusion.
He had previously thought that there were definitely people stationed at No. 23.
In fact, Dark Square wasn't wrong.
