Hearing his answer, I don't know what to say as the reason he started is very reasonable. Even if these Mystic Methods are fatally dangerous, there are many people with secrets that could go around the flaw.

Though most of the time, these methods have been taken by the idiots who have too much confidence themselves. The web has filled the stories of idiots who practiced very dangerous Mystic Methods and lost their lives through it.

"How powerful are they?" I asked curiously. If these skills weren't sufficiently powerful, they wouldn't be shown here as nobody would buy when they had a safe option.

"The least powerful method in the Black Books is twice as powerful than the most powerful method among the while books." said the scrawny Xavier.

Seee!

I couldn't help but sucked a deep breath . I don't know how powerful these methods in white books are, but if they are as powerful as normal speed methods, then the methods in black books should be twice as powerful, which is powerful enough.

I took a look at all the books before I went toward the Black Books, I also have a small secret, let me see if my secret is enough to bypass the fatalness these Methods have.

'Zero Flash' this is the name of the first skill, it lets one have the instant movement, just like the teleportation the flaw it had that one ingredient it had to create a very lethal poison that corrodes the body, one could not leave for more than a month after practicing the 1st level of this method.

This is quite a good Method, and I would choose it if not for me needing the Method that gives me speed to run away, not flash here and there at close distance, as for the poison it produced, I am very sure that Nero would love the powerful poison this method would produce.

I shook my head as I released the book before picking up the second one, just reading the first, I released it back. This method is a freezing butterfly. It is a very powerful method which gives very speed but I could not use it.

It is the Ice-type Mystic Method, which clearly stated that those who have a Fire-type ability or fire constitution should not practice it as it will create a conflict of the element in their body, just reading that I put the book away, I didn't even read the flaw it had.

Now only one black book had remained. If it was not suitable for me, then I will have to choose one of the lesser powerful Mystic Methods in a white cover.

"FeatherLight" is the name of the last Mystic Method, the description said it would make one's movement soft as feather and fast as light. This method is not purely a speed type method, or I may it is a rare Movement+Speed type Mystic Method.

This method fills one's body with a strange energy that makes movements of every part of the body faster, so with the help of not only I could run faster, but my every moment also became faster.

I had thought since it is a Hybrid type method, it must not have that high speed, but when I saw the speed record written in the method, I was shocked because it is the fastest method of the three.

This Mystic Method provides the fastest speed, but it is also the method that kills one quickest. This method runs on the strange energy, which is extremely poisonous to humans. It can kill people within six hours.

"I'll take this one," I said to hear that his expressions changed a little, "Sir, since you are sent by madam Reya, I will tell you some secret about that Method you chose." Said Xavier, his tone had become quite light when he said this.

"This method did not take six hours to kill, but one hour, it could kill you within an hour of practicing its 1st level." said Xavier softly, hearing that my expression changed a little.

"Does this method give the same speed written inside it?" I asked, "Yes, about its speed, we did not lie." said Xavier while touching his chest as if he was swearing.

"Good, I'll take this method and the materials needed for the practice for its 1st and 2nd level, get them ready as soon as possible," I said as I released the book, that book was just a projection which had the details, they will be the real book when I paid for it.

He looked like he wanted to say something but did not say anything, "Ok sir, everything will be ready in ten minutes." he said as he tapped the few buttons on his holowatch.

"Sir, do you need anything else?" Xavier asked to which I shook my head, after that, I went to check our area with him and waited there for my things to come.

Ten minutes later, a lady came in holding a small storage bag and a case, "Sir, you inspect the thing before paying." said Xavier, I did not stand the ceremony and inspected everything in the storage carefully.

"It's all good," I said as I handed him the different storage, in that the storage had the whopping amount of Mana crystal that I am paying them, even I felt the pinch as it took quite a big chunk of my Mana Crystal reserve.

"Sir you can now press your hand on the crystal, the knowledge of Mystic Method will automatically transfer to your consciousness," said Xavier, I nodded and pressed the hand on the crystal and next moment, my consciousness bombarded with information that left my mind buzzed for a few seconds.

This is quite a crafty way to transfer the skill, this way with the restriction placed on the Method, I will not be able to give these Methods to others till I fully practice it which very few people could do especially this method as the last level of it require the power of Peak Adamantine.

"Happy doing business with you sir, please visit our store next time when you visit the market," said Xavier as I left the, I nodded and walked toward the teleportation formation.

It had already been one and a half-hour since I had entered the Black Market, now I have little more than five hours to practice the first level of method, I hope I will be able to do it.

For returning, one does not have to pay the money. So, I directly walked into the teleportation formation and found myself in a completely different location than I had entered.

The entry and exit points of the Black Market are different from each other. The exit I chose is the closest to the hotel I had booked at the exorbitant price. 

Nobody wants a criminal in their establishments, and those who accept the criminals charge them to arm and legs without hesitation without care for the law, the hotel I had booked charged me five times more than what I had to pay normally.

It is infuriating but nothing I could do about since I am Criminal, and in the Grimm Battlefield, criminals have the least rights.
