Unrivaled System

Alex stands at the clouds in the sky's and looks at the surrounding of the assassin's headquarters and sees that all of the building got burned while some building and houses got also affected by the spreading fire

"It seems I have caused unnecessary damage." Alex commented after witnessing what was the effect of his flamethrower where he put every last bit of mana

"Yeah, you were to careless back there, you could have just bought some Mana Potion to regenerate your mana." Sistine said

"I was too excited back then, it was my first time killing, I don't know why but my blood was rising due to excitement when I'm fighting." Alex said

"Just don't do that again, I was worried." Sistine said in a emotional voice

"I love that you are worried about, and Okay I won't do it again I wouldn't want you to worry for me all the time." Alex said

"Mhn." Sistine said

Alex focused his eyes on the building and noticed something strange, it seems another barrier in the underground and also the underground didn't get burned together with building

"What are they hiding in there, for it to be so protected even having a barrier, but it seems there is no more people left." Alex said and is thinking on how to see the inside since his eyes got blurred watching it

"Ah! how could I forgot." Alex exclaimed and then used his infinite with his God Eyes, he remembered that with his God Eye's paired with his infinite his eyesight will improve, that's why he didn't notice that there was a barrier before coming here because when he was still outside his house he used his Infinite and God Eye's to blink toward the assassin headquarters but he didn't notice a barrier then because his Infinite was activated so he sees the underground in the assassins headquarters but when he deactivated it after arriving he couldn't see because of the barrier again

"Maybe I can use this too to see the barrier underground their headquarters and maybe that place too." Alex said when he remembered the two place that his eyes was blurred and this was the third time but this time he can used the power of Infinite, so he wanted to try if it works the same with the other two.

The underground then seems to be getting clearer and clearer until he finally could see everything inside, there was only one room and everything was neatly cleaned and arranged, he didn't find anything strange about the room

"Open." Alex said, out of curiosity he still wanted to go to the room, so he used his Space Manipulation, the space in front of him opened up that connected to the underground, he then passed through the opening of space.

Alex quickly arrive inside the room after he pass through to the space, the room was big it was a bit dimmed because it was an underground, Alex walks all around the room checking some drawers and reading some documents but he still didn't find anything worth it in the room, that will need you to have a barrier.

Alex looks around all the bookshelves, and scanned each one of them but he didn't find anything worth or important in the books

"Is there really nothing in here?." Alex asked

"Maybe they are hidden dear?." Sistine asked

"I am already using my God Eye's though." Alex said

"How about you start destroying the place, maybe a hidden mechanism will activate?." Sistine suggested

"Okay, I will try it." Alex said and tried to used his wind magic

"Gale." Alex shouted and wind cuts started appearing in the the room, some table got cut into pieces and something were cut in half

"It seems there really isn't anything here." Alex said after he uses his skill and sees that almost all of the things in room were cut into halves excepts some books and documents because he wanted to keep them because there is some low-high magics in the room from the five elements also some special and unique magic

"How about you use your weapon." Sistine suggested

"What for? it still won't work." Alex said but sill summoned his weapon

"Gae Bolg." Alex called and the Gae Bolg appeared in his hand and omitted an ominous aura on the air

"Now what?." Alex said while holding his spear

"Dear look there." Sistine suddenly said

"Where?." Alex asked and keeps turning his head

"At your back, in the bookshelves." Sistine said

"Where?" Alex said and turn his back and looks at the bookshelves and sees some dark air oozing in place

"What is it?." Alex asked while walking towards the bookshelf to see what it is that is causing the dark air

Boom~~!!

Before Alex arrive at where the cause all the bookshelf and books scattered from a shockwave

Alex covers his face a bit with his hands from the air pressure, he looks at this front and sees a floating book that is omitting a dark aura around it

"A book?." Alex asked but he then notice that his spear was also omitting it's ominous aura and it seems it is fusing with the books dark aura

"They are resonating?." Alex said because it seems that the book and his spear has a connection

Alex was right the book and spear really did have a connection because they both contained evil aura around them, so when Alex summoned his spear the book quickly notice the ominous aura that was omitted by the spear feeling the ominous aura of the spear the book then also released it's own dark aura and started resonating with the spear

"Sistine do you know anything about this?." Alex asked

"I'm afraid not dear, but at least I know that this book is connected to what a Devil is." Sistine said

"I see." Alex nodded his head and walk towards the book

Alex was walking towards the book but before he could even get closer the book flaw itself to his hand

"Let's see." Alex was surprised first when it suddenly flew to his hand

"It says." Alex read it

"Devil Tome: The Deadly Sin of Envy."
