Small upgrade system

This cave doesn't belong to anyone, so Sam lets them enter. But he didn't drop his guard. He sat in a corner of the cave and silently watched them. You shouldn't let your guard down because some warriors harm other warriors for their loot and other things.

Sam brings out his unfinished food once again and eats. He previously didn't get the chance to finish his food. So, now he can finish his food.

While Sam was eating in a corner of the cave, one warrior brought out food and shared it with the other. They also started eating. They didn't talk that much while eating.

Sam thinks they are also keeping their guard up against him. It was a natural thing to do. He doesn't know why, but he was feeling odd after seeing these three warriors. They were wearing long coats that covered their face and because of this; he didn't get the chance to see their faces. But if you see their body features, then you can tell that these three warriors were girls.

Sam was silently observing them, but sometime later, he closed his eyes to get some. His primary goal was to get some rest, then he will leave the cave.

"Where are you going?" suddenly one girl asked him. Sam opens his eyes and looks toward the girl, who asked him the question. He can't really see her face, but he can tell she has a curious expression on her face.

"Fourth floor," He said to her and once again closed his eyes. He wasn't interested in talking.

"Then you should be careful because recently some D-grade ghost came towards the outside area of the dead forest on the fourth floor," One girl said to him. After that, no one talked to each other.

__________________________

Something later,

"So, goodbye and thanks for the information," Sam said to them and left the cave. He still has a long way to go to reach the fourth floor.

He once again activates his concealment and goes towards the fourth floor. He needs to go to the end of this floor, only then he will find the gate to reach the fourth floor.

Sam can see many warriors who were fighting with those ghost monsters. While going towards the fourth floor, he sometimes helps the warriors who have disadvantages against the ghost monsters.

Five hours later,

He finally reaches the fourth floor. Just when he was about to enter the dead forest on the fourth floor, he heard a roar of a ghost monster. And it mixed this roar with a fear aura. It was a D-grade monster.

Sam can feel the fear aura, but he has a C-grade mental protection technique. Because of this, he wasn't that affected.

He quickly went towards the source of the roar. Who was fighting with this D-grade monster and why the hell this D-grade monster was in the outside area of the dead forest?

He saw ten peak E-grade warriors fighting with a Black Dog, who was a D-grade monster. fifteen intermediate E-grade warriors were on their knees. The fear aura affected them.

Sam instantly didn't help them, because he needed to understand the situation. Why was there D-grade fighting with the peak E-grade warriors? Usually, you only find them in the inner area of the forests.

Five warriors were casting spells while the other five warriors protected them using their light-shield spells. Any type of Light spell was effective against the ghost but the light shields were only an E-grade spell. Because of this, they weren't that effective against the Black-dog.

"Quickly crouch down," one warrior, who was casting the spell, suddenly yelled. Those warriors who were protecting them instantly crouch down and instantly the other five warriors release their attack on the monster.

All the warriors cast fireballs, and those fireballs combined with each other and made a big fireball. It directly hit the Black-dog monster.

The Black-dog instantly let out a painful cry.

Hearing the painful cry, these warriors thought they finally could defeat the monster, and they started celebrating. But Sam knows that the Black dog wasn't dead, it was just seriously injured and this was a bad thing.

'I think these warriors don't know that when a D-grade monster gets seriously injured, they went into a berserk state,' He murmured. In this state, the monster's power will double, and also its recovery time will increase.

Under Sam's spiritual eye, he saw the black dog recovering at an inhuman speed. Its eyes were glowing red.

'I need to help or they will die this time.' Sam wants to help them. He quickly took out his bow, which was made by the mytheno, and coated the arrows with his spiritual energy. But this wasn't the end. Sometime later, the arrows become flame arrows which contain a massive amount of firepower.

Sam discovered this attribute changing things recently after he upgraded his Energy mode to a C-grade technique. But he didn't release the arrow. He needs perfect timing to shoot the arrow and for this; he needs to wait. Sam needs to kill this monster with this one shot.

Those warriors also realized that the Black-dog wasn't dead. They once again prepared their spell. Five warriors were casting fireballs while other warriors were casting light walls.

Except for these ten warriors, the other warriors had already become unconscious. They didn't have that much willpower or they didn't have any high-grade mind protection technique that can prevent the fear aura from affecting them.

The black dog roars loudly and starts running towards them. From his mouth, he shoots a dark ball toward those warriors. These dark balls were filled with full of dark energy. If this dark ball hit any warriors and if the warrior didn't have any powerful body, then they would be immediately affected by the dark ball. They will lose their vision and hearing, and at the final stage, their heart will stop working.

A big dark ball hit the light shield, but because of these low-grade spells, the dark ball immediately broke the light shield.
