Small upgrade system

If you are wondering why there is no D-grade warrior. Well, D-grade warriors didn\'t come to this dungeon because they won\'t gain any benefit from this dungeon. Who will come to the dungeon where he will only get a lower-grade item?

So, those warriors reached the door and tried to open it. But the door didn\'t even move from his place. Only then do they understand how bad their situation was. They suddenly remember the previous warning of that warrior. He already told them not to enter the room. But they thought he was only telling them because he wanted to collect those loot alone. Now, they finally understand how wrong they were.

"Look like we won\'t be able to open the door until we clear the monsters," Mike said to his teammates.

" Mike, you should never believe Fry\'s words. You should trust the warrior\'s word. If you trust him even a little, then we won\'t be in this situation," a girl said. She was the one who previously trusted Sam\'s word. Freon, the person who didn\'t leave any chance to mock Sam, was now frightenedly looking at those monsters. Now, he didn\'t even have the strength to talk. He was only an intermediate E-grade warrior, so seeing this many peak E-grade ghost monsters coming toward him makes him scared.

"Ahhh!!!!!!!!" Suddenly, three warriors began to scream. Hearing their sudden screaming, everyone at first got startled, but then they noticed that 3 warriors of their team fell to the ground, screaming in pain. They already know what happened. It was the Ghost dog\'s special attack.

Well, these ghost dogs previously wanted to attack Sam with this, but Sam has the higher mind protection technique. So, those attacks don\'t really matter to him.

"Everyone, activate your mind\'s protection. Those ghost dogs were attacking us. Try to stay alert," Mark quickly said to them. Everyone nodded. At this time, 3 healers of these teams crouch down and begin to use healing rays toward those warriors.

Mark and the others were looking at those monsters with full alert. Seeing those warriors stand like those monsters instantly increases their speed and quickly approaches them. Mike and others know that they won\'t be able to escape without a fight.

Everyone brings out their weapons and is ready to fight those monsters. Instantly, those spiritual warriors started casting spells, and within 2 minutes, they finished casting. In these 2 minutes, those monsters came very close to them.

With no hesitation, those spiritual warriors attacked those monsters with their attack. All of them cast fireball spells. 6 of them were spiritual warriors. Among those spiritual warriors, 3 of them were healers. So, only 3 warriors attack those monsters with their strongest techniques.

Those 3 fireballs hit those monsters. Instantly, those monsters roared. These fireball attacks killed 3 monsters. All the remaining monsters were angry at seeing that. They instantly prepared a dark energy ball. Seeing this, all the warriors\' faces become pale.

"Prepare to defend," Mike shouted.

Those monsters didn\'t need that much time casting the energy ball. In just under one minute, they were done and instantly they shot toward those warriors. [A/N: These spiritual monsters, or we can say ghosts, were created by dark spiritual energy. They can use the dark balls.]

Those physical warriors bring out their shields to protect them from the attack. Normally, physical attacks didn\'t do that much damage, but all those physical warriors had fire swords. It was like the sword Sam has. Well, at first Sam also thinks with his fire sword he can\'t damage these spiritual monsters. But, in these five, he realized how wrong he was. His sister didn\'t give him any low-grade sword. The phoenix has high-grade fire crystals that can damage spiritual monsters. But, well, you know he uses his slayer all the time. Because of this, he got to know this later.

Now, back to the main point, the shields those warriors placed in front of them have high-grade light crystals. So, that can defend them from the dark ball. This attack happened so quickly that those spiritual warriors didn\'t get the chance to cast another spell. They can only helplessly look at the scene.

Those dark balls hit those shields. The warriors use their strength to fight back. Those dark balls were so powerful that almost all the warriors were sent flying. But they still hold on. There are only 6 warriors who defend those many dark balls. It just matters of time before those warriors were hit by the dark balls.

They were using so much strength that now they were bleeding from their mouth. The power of these dark balls was so intense.

"Light shield." Those 3 light element users cast the light shield. Instantly, a light aura covers them. Finally, those warriors can relax a little.

"We won\'t be able to hold much longer." One light spell user said. It once again despairs those warriors. They don\'t think they can win against these many monsters at the same time.

___________________________

Sam, at this moment, silently enters the room. Nobody noticed him. He also already activated his concealment technique. Just seeing the situation, he can tell he needs to help those warriors or they will be dead.

Now, what should he do? He can\'t use his mega fireball or great fireball. Those warriors were very close to those monsters. So, he brings out his night and a spiritual arrow. He will attack those monsters with his firebird arrow.

He began to focus on sending spiritual energy into the arrow as much as he could. Those warriors were waiting for their death, those monsters were preparing for another attack, and Sam focused on his arrow.

Well, Sam was the first one to complete his attacks. Instantly, the arrows quickly go toward those monsters. Those monsters and warriors suddenly saw a fire bird-like thing coming toward those monsters at very high speed. They just only get a glance at the bird when the arrows hit those monsters. It instantly creates destruction, but not like his mega or great fireball.

Dust covers the view of everyone. Those warriors are unable to tell what\'s happening. They can only look at the scene while standing like a statue. But Sam didn\'t waste his time like them. He instantly brings out his Slayer, and he coated the sword with spiritual energy. He approached those monsters.

He knows his attacks very well. It can kill hardly 10 monsters, and for those remaining monsters, he needs to deal with them personally.

Those warriors who were in a daze instantly felt something or someone passed them. They weren\'t able to see anything in this situation. Well, Sam already deactivated his concealment technique. He wanted to use this technique to deal with those bosses.

As he thought, only 10 monsters were dead. But the remaining monsters were in a confused state. They didn\'t even feel well if someone attacked them. Only then did they see a figure coming toward them. The figure was getting closer and closer to them. They knew this figure. It was the warriors who had already killed their 50 teammates. Now, he is back once again. It makes them angrier.

"Roar!!!!" They roar and run toward Sam. He was fast compared to those monsters because of this. Those monsters didn\'t have time to attack him with a dark ball. The two bosses also see him, and they begin to prepare their dark ball.

Wasting no time, Sam began to kill those monsters. Right, left, he began to swing his sword and kill those monsters. Those monsters were trying to attack him, but he easily avoided them.

The dust began to clear and those warriors finally saw a warrior fighting with those monsters. 17 monsters were already dead, now only 10 monsters remained. Seeing that scene, they once again recover their confidence.

"Guys, attack!!!" They began to run towards the monster. Well, Sam didn\'t need their help, he can easily finish these monsters. But, at this moment, he felt danger from his right side. Instantly, he jumped backward. Two dark balls hit the place where he was previously, and destruction occurred. Instantly, dust speared and blocked the vision. These two dark balls power so much that the place where Sam was standing previously was now gone. The ground was destroyed and you can see a big hole in it.

Sam didn\'t need to guess he already knew that these two dark balls were from those bosses. He looks in the right direction and sees far from his place that the monster was standing there. Those two were the boss of this room.

Hidden turned around and looked at the peak E-grade monsters and those warriors.

"Can you handle them?" He asked those warriors. He doesn\'t think they will be any problem now; those warriors can now easily handle these 10 remaining monsters.

Those warriors also know that Sam wants to deal with those to the Boss. So, Mike replied to him, " don\'t worry. We can handle them. You can focus on the bosses."

Sam only nodded and vanished from his place. Using his full speed was going towards bosses. Now it was time to finish the boss.
