Small upgrade system

Right now, those people are on the last floor. They already came to the boss room after searching around the floor. This is the final place they will search but if they still did not find anything related to the core, they will leave this dungeon. Sam doesn't know but these people have many of their subordinates, they were also searching in different Dungeons.

Everyone right now came to a big dark room. Because of the hole in the ceiling, moonlight is able to enter this room and with that moonlight you can see around but still it was clear. Sam also follows those people this time and he also enters the boss room. He can feel the creepy feeling while he enters this room. Right now a pin drop silence was present in this room and he cannot see any Monster around this room but don't know why the moment he entered this room he was feeling cold.

"Quickly, find that monster. We did not have that much time to waste," suddenly at this time the leader of that group said that. Only at this time Sam noticed those people. Even though he wasn't able to see their faces, one thing was clear that all of them were calm in this situation. Well Sam can already guess the reason behind all of this. All those people are powerful compared to the Boss monster and because of this they did not want to waste any more time in this place.

Suddenly two of them extended their hand and a light ball began to appear. But it wasn't there. One after another the light balls began to appear and the whole room was now full with those light balls. Only at this time Sam finally notices the Boss monster. But most likely those people did not want to waste their time. Suddenly those light balls quickly went toward that was Monster and out of nowhere they began to attack the boss monster.

The Boss monster wanted to avoid those attacks and you can say that he was successful but unexpectedly more of those light balls appeared and right now the Boss monster was surrounded by those light balls. Wasting no time those light balls begin to attack that Boss. Sam was completely and familiar with that attack and because of this he doesn't know anything about this. But one thing is clear that this attack was very powerful. It only take those people 5 to 6 minute to kill the Boss monster.

"Sigh, leader, we did not see anything related to the core. Most likely we just waste our time." After killing that Boss monster those people begin to search around the room but they did not find anything related to the core.

Their leader also sighs after hearing that.

"Sigh, we just waste our time here. Let's get out of this Dungeon. Let's check out the others, if they found something or not." After saying that the leader suddenly brings out a scroll. He quickly crushed that scroll and instantly all those people began to glow in white color. Less than a second later, all of them vanished from that room.

Sam who was just hiding all this time was really surprised very much after seeing all of this. These people were really very powerful. Only two of them were able to kill the Boss monster in just 5 to 6 minutes. Not only that, they also have something that teleports them from here to their next destination. You can say that Sam was very much shocked after seeing all of this and he was now feeling an urgency in his heart. He quickly wanted to leave this Dungeon and contact saints. You wanted to know if the Saints know anything about it or not.

Sam quickly put all the loot in his inventory and then left the room. He was now using his full speed to go toward the exit of this floor.

12 hours later,

Finally Sam once again came back to the second floor. Right now he is resting. You can say that after activity the concealment technique for at least 12 hours it really put pressure on his body. Because of this right now you can say that Sam was mentally exhausted. Before continuing on his journey he wanted to rest for sometime. Even though following those people he did not find any clue about their origin but you can say that he got a lot of good loot while following those people. Those people weren't interested in the loot, so Sam just collected them and stored them in his inventory.

Around his base he already set the monster repealing device and also set the life sigh detecting the. Because of this he can relax while resting. He was now looking at the loot that he got from those people. Everyone of those loots are good but the most good thing was that in the boos room he found a limit breaker. It is also a special Grade limit breaker. Using his supreme upgrade he could upgrade this limit breaker to the next grade and then his sister could use this.

Next day, 2 p.m.,

Sam is finally out of the Dungeon. Westing no time he quickly contacted Saint Markus. You can say that because of the previous incidents he already has a very good connection with Saint Markus. Actually if it was before then he did not want to disturb those saints and wanted to inform his teacher first. But right now his teacher is in a critical condition and he did not want to disturb her. Because of this, Sam decided to directly contact Saint Markus.

Saint Markus is also coming back from a S-grade dungeon. He went to the Dungeon to kill the Boss monster. After killing that, he finally came out of the Dungeon. Compared to other Dungeons you can say that the S-grade dungeons were really different. All the monsters inside of this Dungeon were very intelligent and not only that but this type of dungeon had only one floor. It was like you will directly go to the boss room and you will face the Boss monster with his subordinates.

He was now floating in the sky while looking at those Warriors that were on duty. Actually compared to those other Dungeons, entering a S-grade Dungeon was really different. Before entering the Dungeon every Warrior who guards the Dungeon gate checks the requirement of a warrior or his group. Every group of Warrior should have 10 people of peak A-grade warriors, or if someone wanted to solo, then he needed to be a S-grade warrior. Only when the Warriors fully feel this criteria can they enter the Dungeon.

Markus was looking at those Warriors while thinking something but suddenly at this time his phone began to ring. Westing no time he quickly looked at his phone and saw that it was Sam who was calling him. He begins to get confused because he isn't able to guess the reason for his calling. But quickly pick up the phone.

"Hello, sir, this is Sam Kainer. I just wanted to ask you if you know anything about other people in the world's people?" Sam did not waste anymore time and directly asked him this question.

On the other hand, Markus after hearing his question for a moment wasn't able to think for a moment. But a second later, he finally came back to his senses and only then did he realize that Sam was asking him if he knew about any other world people or not.

"Why is this sudden question Sam? Did you see anything?" Suddenly instead of answering the question Markus asked him this question.

"Yes sir, because of this, i am asking you this question." Sam directly says that he found some clue about the other world people and because of this, he asks him this question.

"Sigh, Well, I will tell you about it later. Wait for me, I need to finish my work first. Also, don't tell anyone anything about this. Not even your family." After saying that Markus hung up the call.

Sam on the other hand gets more confused after hearing the order from Saint Markus. Even though he did not give him any answer, that reaction was enough for Sam to say that he most likely knew nothing about those other world's people.

Sam put the phone in his pocket and then walked toward the parking section. He wanted to go back to his house and after freshening up he will think about all of this. But still while going toward his home Sam just only thinking about those weird people and also thinking about Saint Markus. He told Sam to wait for sometime because he was busy. Because of this, Sam goes back to his house. But still, Sam can feel that most likely Saint Markus knows something about this. But he just didn't want to tell me. Most likely before giving me any answer he wanted to talk with his teammates.

'Sigh, what a complicated life I am living,' Sam sighed.
