Leon read the explanation of the title and he gasped in surprise. After he got the title he and his offspring would count as inhabitants of this world and gained protection of the system. Leon also could share his protection with anyone. He could also learn any knowledge which was in the system without needing to pay anything, of course he needed to pay for material things but for knowledge, he had unlimited credit.
Seed of Tree of Life or World Tree was easy to understand. It was a seed filled with endless vitality which could give birth to a world. It was very rare and precious, but for Leon it signified that didn't need to find any resources with life attribute but Leon didn't know any death attributed treasure which could neutralize World Tree seed. The seed didn't just contain life in it but also wisp of creation thus the seed of world tree was majored in life and minored in creation. He needed to find something with majored in death and minored in destruction. If he were to absorb the seed, he would simply explode from excess life energy. The best he could do, was to find something exact opposite of the seed.
This was a problem he could deal later, but he was curious about the truth of foreign elements and dungeons. Leon got the highest clearance so he could at least search it in the network of the system. Leon didn't find any clue about it in the highest clearance, that meant the ones with highest clearance also clueless about it. But Leon find the truth in a message from the system that exclusive to him.
The system explained that there was intruders who wanted to colonize the system world. The foreign elements was to suppress the system and make laws of the system world more suitable to them. It wasn't the sole reason, with the elements suppressing the system, they could move undetected in the world. The system didn't know what they were doing and didn't send the information about the invaders because it'll bring disorder and panic. The system also didn't know the number of the invaders. Only thing that the system could do was to seal the foreign elements and make inhabitants stronger with the dungeons.
After learning truth, Leon understood the reason of the dungeons. The system was world consciousness and it didn't have any emotions but it could know what was the best for itself also wanted to protect its existence. Even if it didn't give the world tree seed as a reward, Leon would still absorb the foreign elements.
Leon stood up and looked around for the chest, he might absorb the foreign element as a reward but if there was more reward, he would gladly take it too. After looking around the mansion and searching for it, Leon found it and opened it. There wasn't anything aside from a red stone which was looking like a semi-crystal. At first Leon didn't know what it was but after he looked at it through identification of the system, he was shocked. It was the philosopher's stone, he didn't think he would get such overpowered treasure from the chest.
He wanted a cauldron for alchemy but he didn't need to find anymore. The philosopher's stone had ability to dissemble and assemble any material and make qualitative change in the nature of the material. Leon immediately cut his finger and smeared his blood on philosopher's stone and passed his mana through it to make it his own. The philosopher's stone shrunk and entered his mana pool.
Leon looked at his mana pool and saw his poison pearl, portable garden and philosopher's stone inside. He didn't have too much treasures but all of them were extremely precious and could invite calamity if news about them were to leak.
Leon didn't immediately leaved the mansion but he looked around a bit more if there was anything hidden but aside from a few books, he didn't find anything, thinking that he didn't know how much time he spent to absorb the foreign elemental he walked towards the door.
…
"Young master, Could be an accident occurred? It's already fifth day." Asked Heinz looking to the door and they were waiting Leon for five days. Heinz was naturally worried. Theo didn't shared his worries, he was calm as he pointed Hermes who was napping on the ground.
"Look that griffon, do you see how he is relaxed? He was uneasy when Leon hurt, it shows that he could feel Leon's injuries. But in this five days, he simply slept and didn't do anything aside from eating."
Hearing that Heinz relaxed but he was still worried. Leon could easily kill the monsters and he wouldn't spend too much time while doing so. He didn't know what monster in there but he didn't want to see it. A monster which couldn't be killed easily by that "monster", thinking about it made him uncomfortable.
"I won" said Cole, spreading cards on his hand on the ground. Seeing that Theo made disappointed expression and placed his cards too. Heinz was still holding his cards, he was the only one who faced the door and he was still looking at the door. Seeing that he didn't reacted Theo was about to call him.
"You were playing cards huh."
Hearing that Theo and Cole looked towards the door to see Leon was looking at them. Theo stood up and went to Leon's side and patted his shoulders.
"You finally came out. It is good."
While he was patting Hermes got up where he laid and went to side of Leon and started rub his head to Leon. Leon also patted his head.
"We can finally exit the dungeon. My job here is finished." said Leon, looking at Theo. He nodded as response. He didn't ask what he saw there because the system didn't want to them to enter so it would be reasonable, it would also forbid Leon from speaking about it.
"What was the monster there?" Theo could figure it out but Heinz didn't so he couldn't help but ask. Leon shook his head and said;
"I can't talk about it. It's forbidden." when he said forbidden, Heinz recalled how the system stopped them and nodded.
"How is your training going? Have you opened your mana pool?" Asked Leon. If Theo opened his mana pool, his chances would be higher for him to take seat of the next marquis.
"I've opened it. You don't know how happy I was." Theo said smiling ear to ear while his hands shaking. Leon could see that he was still thrilled so he could tell that he should open it not long ago. Leon nodded.
"Then the position good as yours. Theo I decided what the reward that I want. Eye techniques, I want eye techniques as much as possible."
"Eye techniques?" Theo didn't understand why would Leon would want it but he still nodded. Leon was going to ask for water from primordial well but after gained access to the highest clearance of the system, he could go and get it by himself. But when he saw the air elemental with the aid of the system he was shocked but he also thought if it wasn't air but fire and the system didn't helped him to see. He might be titan who could devour four elements and yin and yang but he could also be injured by a fire which was above his level. So not seeing them was the real problem for Leon.
He completed his book of knowledge so he could make an eye technique for himself which was suitable to him but to do so he needed a large amount of techniques to compare them and create the best he could do.
After Leon cleared the dungeon, They didn't linger in the dungeon. They gathered their camps and equipments then they leaved the dungeon to go fief of Theo's family.
