The most important thing is, Xu Xin himself absolutely couldn't do this operation.
Every crossbow in his treehouse, manually controlled, can only be operated through the joystick on the wall. For him to simultaneously fire three crossbows together, it's just impossible.
There's a required distance between each crossbow, even if he moved at light speed between them, it's impossible to make them fire simultaneously and hit the ground at the same time.
This... must be the special ability that the person in front of him possesses.
That's what he thought just now.
But now, observing the person he just knocked out with a kick, he felt like his guess might be wrong.
This person is only wearing a green-tier leather armor set, not even a blue-tier one!
Moreover, upon rifling through the green-tier backpack he had just taken from this person, apart from the long knife in his hand being a blue-tier stone tool, everything else—tools, weapons, etc.—were all green-tier.
