Black's fist slammed into the iron door again, and it wasn't a punch, there was almost no pause, the black fist quickly retracted, and then hit again, like a piledriver, constantly waving its fist and smashing it in the same position of the iron gate, and finally, after I don't know how many times the impact, the iron gate could no longer withstand such a heavy blow, and the entire iron door was completely knocked out.

Behind the Iron Gate, there were stunned soldiers and magicians who blessed the Iron Gate with reinforcement magic, what are you kidding, is this man an assassin or not? How can an assassin have such brute strength that is not inferior to that of a warrior?

The layer of black armor covering the black fist receded into his body, it was actually the bone on his fingers, and he just turned the bone into armor and covered his arm to achieve a defense beyond ordinary people, against the recoil force brought by the bombardment of the iron gate.

And Marion was not mistaken, the layer of substance covering the black hand was black lazuli!

Although black lazuli is called "stone", it is actually a metal, and probably the hardest metal in the world, and Apollo used it to create armor before.

That armor, even Arthur's iron-like sword could only leave a white mark, and even after Leon used the "power of correction" to shatter the bones of Apollo's body, his armor worn outside was only slightly deformed, enough to see the terrifying power of the black lazuli.

Black lazuli is indeed very valuable, so Luo Lan asked the "Eagle Falcon Eye" to get a bunch of black lazuli, although the old man always looks like he eats soft rice, but after all, he is the first machine master in the mainland, and he can always earn it if he wants to make money, especially when his life is threatened......

For ordinary people, the handling of black lazuli is also a problem, Apollo took several years to create that black lazuli armor, but after all, it is the "Shadow of Killing", even if "Lanya" is not around, cutting black lazuli is still very simple.

In the past month, the transformation that has happened to Hei has been tragic......

Luo Lan had said before that in the black generation, the blood of their clan was already very thin, and his grandfather, who taught him the skills of Hei, also said that he couldn't go further, because he was limited by this body.

And that limitation, very simple and straightforward, is the hardness of the bones!

As we all know, the skills possessed by the black clan are based on a thousand bones that can move freely throughout the body, many years ago, in the bloodline of this clan, the demon bloodline still had an advantage, at that time, the hardness of the bones in their bodies was dozens or even hundreds of times that of human bones, so they could withstand the pressure of bones during battle.

But with the continuous dilution of the demon bloodline, the "Inhuman race" as a whole is getting closer and closer to humans, and the black race is naturally no exception, although the number of bones is still the thousandth, but its hardness is getting closer and closer to humans, that is, it is becoming more and more fragile.

Such innate conditions greatly limit Black's strength, and the stronger the strength, the more obvious this restriction will be, like a shackle, locking his possibility of going further, and if this continues, it will never be possible to reach the "hero" realm.

Then the way to break this shackle is actually very simple, that is, to change the material of the bone!

What Luo Lan did was to take out the thousand bones on Hei's body one by one!

Then, according to the shape and size of the bone, the black lazuli that had been prepared long ago was made into the exact same shape, placed in the place of the bone, and replaced the original fragile human bone with black lazuli, the hardest metal in the world.

And in the process, in order for the bones put into the body to fit into his body quickly, Kuro must always stay awake!

That is to say, Luo Lan cut through Hei's body one by one, took out a thousand bones in his body, and then put the black lazuli into Hei's body one by one, and in this process, Hei must also stay awake throughout the process.

This is the origin of the screams that lasted for a month in that small cabin, the scene was so tragic that even the battle-hardened "Eagle Falcon's Eyes" broke out in a cold sweat, of course, the old man also played a very important role in this process, not only providing materials, only with his pupil skills can he see the location of every bone in the black.

This pain is really not something that ordinary people can bear, once the fainting passes, the newly added bones will not fit with the body, and they can only fail, originally Luo Lan was only expected to be able to replace about 30% of the bones, but Hei's willpower far exceeded Luo Lan's expectations, and finally achieved 100% completion!

This process, even if the current black looks back, it is all over the body, it is a pain that I never want to experience again, I am afraid that I will not be able to forget this month's torment in my life......

But the power obtained by this sacrifice is also unexpectedly powerful, without the limitation of bones, if black was limited by the hardness of bones in the past can only exert ten percent of its strength, then now it can be used one hundred percent!

The solidity of the black lazuli is almost enough to support the full strength of the black at this stage, and there will never be a situation that cannot be withheld, this is the new power that the black has obtained.

Now black, the strength is very close to the "hero" realm, but unfortunately, still unable to comprehend the mystery of "extreme speed", the legend of the black clan can use the ability of "extreme speed", which is the fastest in this world, no one can match.

If you can touch the mystery of "extreme speed", you can enter the "hero" rank and become the top powerhouse in this world!

For this reason, the hint given by Luo Lan is "Lan Ya", to find the real "Lan Ya", if you can get "Lan Ya", then Hei may be able to understand the mystery of "extreme speed......

From beginning to end, Loren did not accept Hei as an apprentice, nor did he accept Hei's request, but when Hei left the cabin, he still knelt down and performed the "Inhuman" apprenticeship in the direction of the cabin.

He didn't know if Luo Lan saw it, and he didn't care, but from here, Hei found himself who had been lost for many years, regained the meaning of survival, and got the opportunity to become a "hero".

I also want to say here that after Hei woke up, he wondered where his original thousand bones had gone, until he saw Wangcai, who looked unfinished, had gained a whole circle in the past month......
