"Boom!!!"
With that Alex killed the last red spider. Well, he still did not complete the mission because he was still looking for one more red spider. But fortunately, he has the confidence that if he advances this way he will find those Monsters.
After taking the dead body and the loot in his inventory he begins to advance once again. Well, you can say that all of this happened because he was following those people that most likely came here to kill him. Actually while following them, they suddenly came to this place and those people got attacked by those red spiders.
At first, those two red spiders were not able to see him, and because of this, he just only attacked those two people that mostly came here to Search for Alex. So both parties begin to fight but most likely those fighters underestimate the power of those Red spiders and because of this, in the end, they die.
