Small upgrade system

Sam was now advancing towards the next floor's entrance. He still didn't reach the entrance because this graveyard was pretty big and he wasn't using his fastest speed. He was thinking about the previous incident. Sam noticed the ghost dog was previously sucking spiritual energy from the warrior.

"So, this is how they absorb spiritual energy from the warriors. These dogs were like a vampire, they just suck spiritual energy." Sam thought.

Sam should be more careful from now on and avoid those dogs' bites. He finally understands the danger of these dogs. Because those ghost dogs were only F-grade, Sam didn't face any danger, but what happens when he will those black dogs? If his guess was right, then those black dogs will be at least an E-intermediate grade monster.

Sam can see the next floor entrance. Many warriors also going towards it, like Sam, they also going to the next floor. He went towards the entrance.

..........

Sam was now killing some ghost with his sword. These ghosts have the humanoid feature. You can only see the of those ghosts. They were floating in the air while fighting with the warriors. They were looking like a human spirits.

This second floor was looking like a dark forest where the sun will never rise because he had previously made a fire torch he could see in this dark forest. Sam didn't have night vision, so this was the only thing he can do right now. Sam never guessed that there will be no light in this dungeon, so he didn't learn the night vision technique.

Sam finishes killing the 5 ghosts that were tried to attack him. He collects the loot and starts advancing. Sam didn't know the right path, so he can only advance based on his guess. He walked towards the left side of the forest because he can hear many warriors' voices from this direction.

While walking, he also thinks about the humanoid ghost. They were also F-grade ghosts but intermediate level. These ghosts can possess any warrior's body who has a weak mind and doesn't have any mind protection. They can make any weak mind warrior into a slave, and because of this, they were very dangerous.

'So, these dogs and the humanoid ghost were the only ghosts I can see in this dungeon. Thankfully, I have the mind protection technique or without it, I will be in a seriously dangerous situation. The guide previously only tells me about these two ghosts, so I think there will be no other ghosts, but he also tells me sometimes many warriors face a black humanoid monster. I think that the black humanoid ghost was more dangerous than the black dog. Sigh, I need to be very careful on the last floor.' Sam thought all of this in his mind while walking.

After some time walking, he finally saw the warriors whose voices he previously heard. They were talking about how many ghosts they killed, how powerful they were, and some other bullshit. (A/N: They have the superiority complex.)

Sam quickly understands their character. They belonged to some rich family and they think they were the better. Sam sigh inwardly seeing their behavior and he was ready to leave while activating his stealth. It was better to avoid these kinds of people; you don't want to ruin your mood for them. He activates his stealth mode and disappears from this place using his light walk movement technique.

Sam was running towards where he saw some ghost. He didn't want to waste time, so he quickly brings out his sword (Slayer) and killed those ghosts. Like this, he advanced towards the next floor's entrance. He also meets some E-early grade humanoid ghosts and dog ghosts, but he killed them quickly and, after collecting the loot, he advanced towards the entrance.

In this dungeon, you need to clear four-floor but Sam will not go to the last floor because he hasn't reached the peak grade but if he goes to the last floor, he will face the E-peak grade ghosts. First, he will break through to intermediate grade, then he will try to kill E-intermediate ghosts as much as he can.

After killing the humanoid ghost, he came in front of the entrance. He can see many warriors, some of them were going through the door and some of them exiting the floor. Sam can see some warriors who come back from the next floor had paled faces, some of them shivering. Their teammates supported them while walking.

Sam doesn't know what happens, but one thing he was sure that he has to be careful or his condition also becomes like them. Sam took a deep breath. He needs to calm down his mood. On the next floor, he will face E-grade ghosts from the early stage to the intermediate stage. Even sometimes, many warriors also face peak stage ghosts/monsters on this floor. Because of this, he was nervous. He wasn't ready to face a peak stage ghost/monster.

Sam walks through the entrance. He will not directly teleport to the next floor, but he needs to walk towards it. He needs to walk through these stairs and go upwards. In some dungeons, you need to go upward, and in some dungeons, you need to go down to reach the next floor.

...................

Sam was now resting. In this dungeon, you can't sleep openly, you can't sleep in a tree, you need to some cover place like a cave or you need to make one, and you need to make a firewall around it. These ghosts can pass through any solid object because of this you need fire around your creating place. These ghosts fear fire.

Sam didn't find any cave around him, so he made a simple base. He simply makes a big hole in the ground, then with the help of trees breaches and leaves, he covers the hole. He then makes two holes in the cover area. You were all thinking that it was an idiotic idea. What happens if any warrior walks through your cover? He will fall down. But that won't be happening, because Sam places many fire torches around the cover area.

(A/N: I watch a video where I saw a guy making an underground base and from there I got the inspiration. Hahaha.)

To be continued....

[A/N: Happy hug day guys. Those who have girlfriends should hug their girlfriends and those who don't have girlfriends like me can only do one thing, they can only hug their pillow while reading some novels. Hahaha.]
