'Tsk it was harder than I thought' Fia thought after killing the monster and then falling to the ground from exhaustion.
"Is it done?" One said seeing the monster killed for unknown reasons, the tentacle was cut laterally and small burn marks could be seen, the upper part of the tentacle fell, starting to release a kind of liquid from the cut part, the color was white but also a little yellowish.
Brian turned his head slightly and saw a woman with red hair that was gradually becoming black on the ground while she was panting heavily.
Brian quickly approached and asked worriedly: "Are you okay?"
Fia panting raised her head slightly and saw the man with all yellow, with a little sweat on her face she smiled slightly but the smile was almost imperceptible and said: "Yes."
After that answer twenty minutes of rest passed, Fia had recovered but the backlash of the archetypal union was still felt, she was near the cut part of the monster advocated lightly, with a glass flask.
The liquid that came out of the monster turned out to be a type of a specific type of fat. With a cork Fia closed the flask and looked at the liquid.
'As soon as we get back I have to have it analyzed' Fia thought with the flask in her hand, the most precise chemical analyses or anything else were not for her besides the fact that you need the class [Scientist] or [Scientific Researcher] to do precise analysis and do various tests with materials and discover the properties.
"Ahhhhh, how boring!!" Fia said exhausted sitting down suddenly raising her head upwards.
The people were slowly recovering and as soon as they recovered they headed towards the large door but first they did a little check on the "puddle", the "puddle" turned out to be nothing more than a huge amount of that particular fat, however they were unable to take many test samples the maximum was about twenty.
The surviving hunters approached the door and tried to open it, however the door did not move a millimetre.
The large stone door seemed anchored to the ground, or rather no it seemed that it was actually part of the ground. Despite the various attempts and various blows the door remained where it was it did not want to fall.
Even Fia's analysis gave no results the door was marked as a simple stone door. Fia began to make various theories and tests with magic, but nothing at all gave no results.
It was also very difficult to scratch the door, it didn't even have a scratch despite the various attempts, it seemed completely frozen.
Fia touched the door closely with one hand to try to understand how thick it was putting pressure on the door.
Crack!
A slight cracking noise was audible, Fia got scared and saw that the door was shattered even if only slightly.
'What happened?' Fia thought seeing that situation.
Many approached her to ask what happened or that she found a method but Fia replied that she didn't know either, she had never seen something similar. It seemed like a stone that had split in half due to the erosion of the water.
Even though the crack was small, a small possibility of success could be seen, even though the crack even if hitting that point with force didn't scratch it at all.
But something must have happened little but surely... Fia thought trying to understand something, while she cleaned her hands she felt an oily substance on her hand, it was the grease of that monster.
'Don't tell me what? No impossible! But I have to try' Fia thinks and she takes out a flask with the monster's fat from the item box, removes the cork and pours some against the wall.
Crack!
The same noise was heard, and the stone shattered, at that moment Fia understands, that fat was nothing more than a substance that forcibly breaks down chemical bonds, but for some strange reason on normal rock it doesn't work, is it perhaps that it only works with special materials? It was the question that ended up in Fia's head.
Mhhhh, maybe this liquid only works with objects? No, I don't think that's the right definition, materials? Maybe, that's the most plausible one that comes to mind, for sure. This liquid is unique because if it can dissolve the bonds of some materials it could be a sensational discovery, it could be equivalent to gold... Fia thought, while a thousand questions floated in her head.
Without wasting time Fia decided to call Brian in which being that he has a hammer could create a huge opening to enter the dungeon.
When Brian approached Fia she explained the plan, and he instantly approved. Fia took the already used flask with almost more than half of the liquid present and poured it on the huge hammer probably made of special steel.
Fia also applied wind magic on the back of the hammer to give a mega boost. Before Brian got into position to strike with all his strength, Fia stopped him for a moment to tell him to prepare for a possible backlash if the wall doesn't destroy in case of an excessive backlash Fia will heal him.
Despite the warning, the yellow-eyed man paid little attention to it and with all his strength prepared himself. Brian consecutively activated [Physical capacity increases] [Wild strength] and got into position placing the hammer covered in that liquid that was slightly dripping. He gave himself a push slightly running and screaming as if he were the protagonist of a shonnen manga and with the help of Fia's magic he reached a speed extremely high and that blow and the hammer met the "wall" made of special stone and destroying the large stone door opening a passage, revealing the various rewards that were hidden at the end of that great cave that killed many hunters.
Author's Note: From this moment the spells will be called as "wind" etc this is because I found it difficult to remember but narratively speaking it will always be "Cyd" etc
