Chapter 232 - Information 

Right now, Sam was with his friends. After coming back to his base, he already wakes up everyone and then he informs them about these people. After listening to all the explanations from Sam, they sigh in relief because Sam is able to take action before those enemies attack them. If some did not take action at that time, then those enemies already would have spread the poison, and that poison would definitely kill them. 

After they calm down, they focus on that unconscious person, or you can say the enemy. Sam did not kill him because he wanted to know the information from this person. Also, he previously heard that this person has some kind of connection with an information source that told him about his location. He also wanted to know about that source. Which information source was giving all those enemies their location? This was very important information he wanted to know from this person.
