Small upgrade system

One thing Sam notices about the Goblin captain and the Goblin soldiers. The previous Goblin captain and this goblin captain were equally powerful. It was like all the Goblin captains were very close to a breakthrough to the next grade. So he guessed that, most likely, those Goblin Soldiers were very close to breaking through and he turned into a Goblin captain. He cannot think of any other reason other than that.

Sam has already started casting his mega fireball. But one thing you should know about his concealment technique is that when he casts any spell that any monster can notice who is good at spiritual energy sensing. Actually, he will not be noticed by the monster, but the monster will notice the spell. Because when he cast any spell, a huge amount of spiritual energy went toward him. There were many monsters that could feel the change of spiritual energy. Those monsters could easily spot him, but fortunately, these goblins couldn't feel the change of The Spiritual Energy so they did not spot Sam.

Sam was hiding in a gigantic tree. From here, he can easily spot those goblins, but those goblins won't be able to spot him. He needs some minutes to finish the mega fireball. Even when casting the mega fireball, he did not shift his focus to any other thing. He only looked at those goblins. He did not want those goblins to suddenly finish from his sight.

Fortunately, there weren't any warriors here, or it can be dangerous for those warriors when he throws his fireball toward those monsters. You already know how powerful his mega fireball is.

Sometime later, he already finished casting his mega fireball, but now those goblins were far from his place. But that would be any problem for him while throwing his fireball toward those monsters. Wasting no time, he threw the fireball, using his full strength.

The fireball went toward the goblins quickly. If you saw that right now, you will think that someone fired a laser gun toward those monsters. In the end, the Goblin captain seems to feel the danger. There was a blue thing coming toward him. He doesn't know what this thing was, but he can sense the danger from that blue thing. He wanted to avoid the blue fireball, but he wasn't that fast. Very quickly, the fireball hit the Goblin captain. Instantly, destruction appeared. All the surrounding areas where the fireball hit got destroyed.

Sam wasn't sure if he already killed that Goblin captain because he was unable to see what was happening. It was like a firewall appeared in that area. Everything is burning in the area. The trees around that area become dusted by the blue flame instantly.

Sam was panting. Really making a mega fireball was really exhausting for him. He almost needed to use all of his spiritual energy to cast a single mega fireball. His concealment technique already got deactivated. He quickly brings out a spirit energy potion and drinks it. He also uses his energy recovery technique also at full speed. But even in this situation, he only focused on those monsters.

The fire slowly started to fade away, and he was able to see clearly what happened to those goblins. He did not see any goblins there. It means they have already turned into dust by the mega fireball.

"Sigh," Sam sighs in relief. For a moment, he thought the Goblin captain was still alive. You can say he already recovered his 60% energy. So he once again activated his concealment technique and became invisible. Well, he was able to recover quickly because of the high-grade spirit energy potion. Even using his energy recovery technique, he still needed 15 to 20 minutes to fully recover, but while using the recovery technique, if he drank a potion, then the process became very fast. The more powerful the potion is, the more you will recover.

Sam quickly came to the place and collected all the loot. After that, he did not waste any of his time and left the place.

Sam doesn't know, but just when he left the place, a group of 10 warriors appeared there. If you see their clothes, then you can tell they were from the Royal academy. They were also releasing a peak and intermediate D-grade warrior's power. Well, in the dungeon, normally warriors did not hide their power. The main reason behind it is that it can scare those lower-grade monsters. Actually, no one wanted to deal with a lower-grade monster that won't give them any good loot.

"Fiona, what do you think? What happened here?" A warrior suddenly asks the girl standing beside him.

"Zen, I think someone uses a blue fireball to kill goblins. We already saw that the area turned blue for a moment. So naturally, someone used a blue fireball, and that fireball made this destruction. Also, if you try to observe them, you can feel the huge spiritual energy fluctuations in this area." Fiona told the boy.

" The thing I was most interested in was to know the person who uses the blue flame. It wasn't easy to reach that kind of flame control. Someone should be very powerful here who uses this fireball. And by looking at the situation, I could tell he had already left the area. I really wanted to meet that person who uses the blue fireball." Fiona said to everyone. She was the captain of this group. They were from the Royal Academy and all of them were 3rd year like Gloria. They also were participating in the annual college competition, so because of this, they came here to practice.

"Well, don't waste any time. Let's go. We needed to reach the 3rd floor." She said to everyone. No one in the group said anything to her and all of them just nodded hearing her. Well, she was the second-best student at the Royal Academy. Previously, she and Gloria were competitors, but when Gloria broke through, Fiona was no longer her opponent. Now Fiona also wanted to break through so that she was once again able to compete with Gloria.

Our main culprit is Sam. At this time, we are very far away from that place. He won't go to the inner area, he will only travel around the border of the inner area and the outside area. There were two reasons behind this. First one, in the inner area, he could meet many Goblin captains at the same time. That could be really dangerous for him. The second, he only had 3 days, then he needed to leave the dungeon. Because of this, he did not want to go to the inner area where his life could be in danger.

4 days later,

In these 4 days, he traveled around the border, found many monsters, and killed them. His luck also was good because he got the technique from those monsters and he also got many suitable materials from those monsters. Those excellent materials could help him to gain credit points from the college. The good quality loot can give you many credit points from the college. But he won't sell any of the technique scrolls. Well, if he got a useless technique, then the matter was different, but the techniques he got from killing the goblins were really good. He will learn then when he leaves the dungeon. And the good thing was that those two techniques were D-grade techniques. He also gained many crystals and now he just needed to absorb those crystals.

Sam was currently outside of the dungeon and eating some food. This time, he did not sell any of his loot. Even though the loot was useless, he kept them. He will exchange those loot in the college for credit points.
