Small upgrade system

You can say all the monsters on this floor were coming towards them. The humanoid monster called them to fight with the warriors.

All warriors become tense after seeing this many monsters. They can fight with those monsters one by one, but they want to know if they can fight with this many monsters at the same time.

A black dog also was coming toward them. This black dog was the previous dungeon's boss, but now the humanoid monster has become the new boss. This black dog was much darker compared to other black dogs. His eyes were also much redder in color.

All the warriors know the fact that if they want to survive, they need to fight these monsters. They all brought out their weapons and were ready to fight a deadly battle.

Sam also brought out his bow, and he was ready to shoot anytime. He also saw many black Humanoid ghosts that can control the humans who have weaker mind power. They were also immune to any physical attack. The only spiritual attack can burn them. He coated the arrows with spiritual energy and also changed the attribute of the spiritual energy. All the arrows become flame arrows.

Lisa was also only focusing on the boss of this floor. She cannot lose her focus. Any slight mistake can harm her. Only these warriors can fight with those monsters until help from the association arrives. Because this floor exit was locked, warriors from the association needed some time to crack the lock and enter the floor.

She already casts a blue fireball and shoots toward the boss. This blue flame was the upgraded version of the normal fireball. To learn this technique, you needed to buy the C-grade flame technique.

The boss also makes a dark ball and short towers the blue fireball. Those two attacks instantly clash with each other and instantly an enormous distraction appears. A tremendous crack appears on the ground beneath those attacks. The clash also created an enormous shock wave.

Those two didn't waste their time. They shot one more fireball, and the dark ball towered over each other. The clash created one more shock wave. Lisa didn't make any fireball, she just brings out her sword and runs toward the boss. They both know that there won't be any result if they fight in a long-distance attack. Because of this, Lisa plans to fight close combat.

This boss monster wasn't a spiritual monster or a ghost monster. So a physical attack will work against him.

Lisa, with an insane speed, instantly appears in front of the boss and attacks with her sword. The boss monster also prepares for the attack. He blocks the attack with his ax. Yes, the boss monster's weapon was an ax. He also instantly swings his ax with full force.

But fortunately, Lisa crouches down and avoids the attack. She twisted around and kicked the boss. This time he wasn't able to react in time and got sent flying.

When Lisa and the boss were busy in their fight, other warriors were also fighting the monsters. Many warriors who didn't have strong mind protection got affected by the mind attacks. The ghost also possessed many warriors and now they were like walking zombies who were fighting against the warriors.

In this ghost dungeon, warriors mainly used light magic or fire magic. Those warriors know the fact that they won't be able to fight this many monsters. One of Lisa's teammates told a plan.

Twenty warriors stand side by side, and instantly they attack those monsters with fireballs and light balls. After that, they once again start casting spells. When they were busy casting, another team of twenty warriors stood side by side and attacked those monsters. Like this, they were fighting those monsters.

Sam was also killing the monster, but he didn't join the twenty warriors team. He was using his concealment technique, because of this, he was invisible in the monster's eyes. Using his invisible state, he was attacking those monsters with arrows and fireballs, and sometimes, when the monsters got near, he killed them with his sword.

Now he was making a great fireball and instantly shot toward the monsters. It creates a big distraction, and many monsters get killed by it. Many warriors notice that someone was killing those monsters, but they find the person. Most likely, he wasn't interested in showing himself. They can only say thanks to the person. Because he was helping them very much. Every time when this person shorts fireballs, it creates an enormous distraction and kills many monsters.

Sam was now sitting behind a gigantic tree while recovering his energy. Those great fireballs consume much spiritual energy. He needs to recover his energy and then will fight once again.

While he was recovering his energy, he looked at Lisa. She was fighting the boss. The thing was that nobody has an upper hand over the other. They both search for weaknesses in each other.

But Sam suddenly saw that the black dog who was the previous boss of this floor was preparing a dark ball and his target was Lisa. If they can take her down, then they won't be having any problems with the others.

Sam didn't recover his full energy, but he needs to help her, or she will be in danger. He quickly brings out his bow and also prepares a flame arrow. His Target was the dog's eyes. The black dog had a pretty good defense in a normal state, so his only choice was the dog's eyes.

Sam took a deep breath and calmed himself down. He focuses on the dog's eyes and shoots his arrow. This time he shot the arrow with all the strength he had because he didn't recover fully and the dog was pretty far away from his place.

The flame arrow was silently and quickly approaching the dog. Many warriors saw that a flame was approaching the dog. Only then did they notice that the black dog was ready to shoot a powerful dark ball at Lisa. But fortunately, the flame arrow pierced through the dog's eyes, and the dark ball got canceled. All warriors release a sigh after seeing this because they know the importance of Lisa.

No one noticed but Sam was laying down on the ground.
