Evan used his sword and made a cut near the heart of the hyena to look for the core but he was disappointed when he did not find any core inside the hyena.
Evan came near the body of the cat that was already blown away by the attack of the hyena earlier there were just chunks of flesh there, the entire body of the cat was destroyed because of the blast earlier.
Evan tried to look for the core near the destroyed body of the cat monster but when he didn't find anything even after five minutes he stopped looking and sighed "the chances of these monsters having a core were already low so I guess instead of wasting my time here I should move forward and kill other monsters"
Forty minutes have passed since Evan entered the dungeon he now had only one hundred and forty minutes left before the effect of the invisibility potion ends so Evan moved quickly and started to walk deeper into the dungeon.
After one and a half hours Evan was sitting on the ground while panting heavily there were three corpses of rabbit-type monsters lying near him.
During these one and half hours Evan killed seven more monsters but he got only one core from these seven monsters. He now has only forty minutes left before the effect of the invisibility potion ends and he still got only two cores.
"I can't go more deeper in the dungeon or I will not be able to leave the dungeon before the effect of the invisibility potion run out looks like I can only leave the dungeon with these two cores this time" Evan said with a bitter tone because even after doing everything he only got two cores and he can't absorb them because he has to sell them so he can get his thirty thousand credits back and buy another potion so he can once again enter the dungeon safely.
It will take Evan thirty minutes to return to the portal of the dungeon so Evan stood up with a bitter face and started to walk towards the portal.
"At least I got experience of fighting against these monsters when I came here next time I will be able to kill them more easily and maybe I will get more cores next time" Evan said and tried to console himself.
Suddenly Evan stopped because he saw a monster sleeping in the hallway. Evan was confused after seeing the monster because he was sure that he killed all the monsters when he passed by here earlier.
But Evan then remembered that monsters will once again appear inside the dungeon after some time when you killed them.
The monster in front of Evan was a wolf-type monster, the same type of monster that he killed when he first entered the dungeon.
'It will take me twenty-five minutes to reach the portal and I still have thirty-five minutes I should be able to kill this monster in ten minutes maybe I will get a shadow core by killing it' Evan thought after seeing the shadow wolf.
Evan slowly started to walk towards it like last time and didn't make any sound soon Evan was just ten meters away from it.
The nose of the sleeping wolf twitched when Evan was just ten meters away from it, Evan stopped walking and held his breath so that the wolf won't detect him.
Soon the nose of the wolf stopped twitching and Evan once again started to walk towards it when Evan was just one meter away from it he slashed his sword at the eyes of the wolf.
But just as Evan slashed his sword all hairs on the wolf's body stood up because of the danger and without even opening its eyes the wolf tried to roll away from its location.
Although the wolf reacted super fast Evan was still able to slash at the left eye of the wolf.
Howl ~~
The wolf howled in pain when one of its eyes was destroyed. Evan tried to attack the wolf once again while it was still recovering from his earlier attack but just as Evan was about to attack it the fur of the wolf shined in ominous black light.
When Evan saw this he quickly stopped his attack and backed away from the wolf just as Evan backed away from the wolf a cloud of black smoke came out from its body.
When Evan saw the black cloud he felt a chill run down all over his body because when the black smoke touched the hard floor of the dungeon it started to melt, Evan can't even imagine what would have happened if he was a second late to back away from the wolf.
The cloud of black smoke surrounded the area of around two meters near the wolf, Evan looked at the cloud from a little distance and hoped that the paralyzing poison will soon take the effect and the wolf will be paralyzed.
After a minute the black cloud disappeared and the wolf monster once again appeared before Evan. One of its eyes was destroyed and black blood was coming out from it continuously.
After the black cloud disappeared the wolf started to back away slowly and tried to retreat from there but because of the paralyzing poison its legs were shaking and it dropped to the ground.
When Evan saw this he didn't wait and quickly charged towards it and after coming near the wolf Evan slashed his sword at the other eye of the wolf.
Howl~~~
The wolf howled in pain and black blood flowed out from its destroyed eye.
After making the wolf blind Evan easily killed it, Evan wiped the invisible sweat from his forehead and looked for the core.
Evan made a hole near the heart area of the wolf and started looking for the core and when his hand touched something round and solid while searching his eyes lit up and he quickly pulled back his hand.
When Evan pulled back his hand there was a black marble size of a golf ball in his hand, when Evan saw this a big smile appeared on his face because now even after selling two cores to get enough money to buy another invisibility potion he can improve his power a little with the help of this core.
Evan quickly put away the core and stood up to leave the dungeon but just as he started walking towards the portal black smoke came out from the black walls of the dungeon and started to gather at the same place.
Soon the black smoke started to turn solid and took the shape of a flying-type monster when Evan saw the monster he can feel that the monster was just D rank like others but for some reason, his heart started to beat faster, and faster. When the smoke completely solidified a bat-like monster appear before him.
When Evan saw the bat-like monster he almost cursed out loud.
