Small upgrade system

2 days later,

Finally, Sam and Alena were now near the entrance to the next floor. Well, it was time to go to the next floor. In these two days, Sam hunts those monsters as much as he can. Well, he wanted to stay on the 2nd floor more, but then he could come to this later. So, right now, they were going toward the next floor.

"Be careful. These peak D-grade monsters were more intelligent compared to these other monsters. Like those intermediate monsters, you will also see the difference while fighting these peak D-grade monsters. Also, the sandworm will be much bigger than those other sandworms. Not only those sandworms, but those Black Scorpions and those golems will also be bigger on this floor." Alena explains this to Sam.

Sam nodded after hearing the explanation. Sometime later, they finally came to the 3rd floor or the last floor. Compared to those other floors, Sam didn\'t see that many warriors near the entrance of this floor. Even those warriors who were near the entrance weren\'t as cowardly as those other warriors. Most likely some warriors were returning, or they had also just come to this floor.

"Boom!!!" Suddenly an explosion appeared because of Sam\'s mega fireball. Right now, he is facing 5 black Scorpions. He already uses the concealment technique and then attacks those Scorpions. He knows that he won\'t be able to kill them with this one attack. Because of this, he began to prepare a great fireball this time. He didn\'t want to use all of his spiritual energy and because of this, he didn\'t use the mega fireball. But still, he now only has 15% spiritual energy left. He needs this much spiritual energy to maintain his concealment technique.

Right now, because of the dust, he is unable to see anything and because of this; he began to wait for the dust to clear. One after another, because of this big explosion, you cannot see anything because of the layer of dust. Well, Sam already activated the energy recovery technique. Sometime later, the dust begins to clear and Sam is able to see. He saw that he was able to kill only 3 Scorpions, even after using his two powerful techniques. He thought that even though he wasn\'t able to kill the other two Scorpions, he should be able to injure them seriously. But when the dust completely faded away, only then he noticed that the other two remaining Scorpions weren\'t that seriously injured. That surprised him very much. Fortunately, he has already recovered his 35% spiritual energy. So, wasting no time, he quickly activated his energy mode and then ran toward them. Fortunately, he was in stealth mode. So, those monsters still weren\'t able to sense him. But it looked like they seemed to feel the danger.

After reaching very close to them, he already attacked those remaining Scorpions. Well, he did not hold back and used his full energy. Fortunately, with that able to injure one of the scorpions seriously, but still, that scorpion wasn\'t dead. Sam quickly came far away from that place because he could feel that he was low on the spiritual energy and if he still decided to use the energy mode, then he wouldn\'t have the spiritual energy to continue his energy mode. Because of this, he retreated from that place.

This time, he quickly brought the spiritual energy recovery potion and gulped it down. While he was recovering from the spiritual energy, he was only focused on those scorpions. One of the scorpions was seriously injured while the other one wasn\'t that much injured. He won\'t fight those two until he doesn\'t recover his full energy. Because of this, he was now only focusing on those two Scorpions.

__________

While Sam was focusing on those two Scorpions, Alena was flying in the air, looking in his direction. You guessed it right, even though she hadn\'t mastered the wind control technique like her light control, but still, it was enough for her to fly in the sky. So, right now, using that wind control, she was flying in the air while looking in Sam\'s direction. She already saw how Sam shoots two of his most powerful spells, but with that, he is only able to kill 3 Scorpions while these two scorpions are able to save themselves. They also weren\'t that injured because previously, after sensing the danger, they quickly retreated from their place.

She wasn\'t able to see the surprise expression of Sam, but still, she guessed that right now Sam should be so surprised by the result. After that, she saw that suddenly one Scorpion got attacked out of nowhere and this made that Scorpion seriously injured. The 2nd Scorpion was already all around his surroundings because he also thought that he would also attack that unknown attacker. But then, even after waiting for something, he didn\'t receive any attack. With that, Alena guessed that Sam was very low on his spiritual energy and right now he was recovering his spiritual energy far away from that place. Well, she knows her student\'s behavior. Also, compared to Gloria, Sam was more cautious.

Sometime later, she suddenly felt an energy fluctuation, some far away from those two Scorpions, who were still busy searching for the enemy. She also felt that energy was familiar and with that, she already guessed that it was Sam. Most likely, Sam once again preparing his attack for those two Scorpions, and also, judging from the energy, he should use more energy compared to before

_____________

Well, you can say that her guess was correct. Sometime later, after recovering his full energy, Sam was already ready to attack those two Scorpions that were still searching for him. Previously, he used 50% spiritual energy while casting the mega fireball, but this time he was using 80% spiritual energy. With that, you can guess how powerful this attack was. More and more spiritual energy is coming toward his place. Most likely because of this, those two Scorpions also noticed that energy fluctuation was in place. With that, they already guessed that something or someone was there and, because of this, those two Scorpions quickly began to come in this direction.

After seeing that, Sam didn\'t panic. He just calmly looked toward those two monsters. A few seconds later, his spell was already ready. Wasting no time, he quickly shot that fireball toward those Scorpions.

"Boom!" Instantly, once again, an explosion appeared, and this was much bigger than the previous explosion. Once again, a layer of dust appears and, because of this, Sam is unable to see anything. He is already using his energy recovery technique to recover his spiritual energy at this time. It took some time for that layer of dust to become clear. But the good thing was that the Scorpions died.

"Sigh," Sam finally signed in relief and after that, he went toward the place where the explosion appeared. After coming toward that place, he finally saw how much damage he did when he used 80% spiritual energy to create the mega fireball. The whole 1 km was destroyed by this and now you can see a large hole in that area. Fortunately, Sam was able to find the loot and after collecting the loot, he began to look for his teacher Alena.

_________

After seeing that Sam is able to kill the remaining two Scorpions, Alena also sighs in relief. Well, she has the full trust that until Sam doesn\'t meet a big group of monsters or the boss monsters, Sam will be able to win. But still, that last attack really surprised her. She didn\'t think that this would be this powerful. But then she quickly calmed down. Well, she shouldn\'t underestimate Sam, because she knows Sam still has some secret that he didn\'t tell anyone. Well, she thinks that previously Sam never revealed his full power, even when he was fighting with her.

Well, Sam wasn\'t aware that Alena thought of him as a mysterious student, who was hiding many secrets like his own strength. If he gets to know that, then he will be surprised by the powerful woman\'s instincts.
