The pit was too deep, and Li Huan jumped in to look for it for a while, only to find an intact ring and a large sword with a slight dent on the side in a pile of stone dust.

He could see the tiny dent with his white eyes, but Lu Lu couldn't detect it.

As a result, Lulu raised her greatsword to N0.4 with no noticeable notch in the blade.

"Yes, there's a small gap there, but you can't see it." Li Huan said.

"Really? No.4 Can you see it? Lu Lu asked.

The N0.4 warrior replied with a blank face, "The weight of the sword has not changed. ”

Li Huan was not convinced, and said to Lu Lu: "This is really damaged, if you don't believe it, look for a soldier with a higher number." ”

Lu Lu smiled: "There are no more higher-numbered warriors in the organization, No.2 and No.3 were both killed in the crusade against Livlou, if you want to prove that this greatsword is indeed damaged, you can only wait for the organization to create a stronger No.1." ”

Li Huan rolled his eyes, of course, he couldn't see this expression, and said, "The trainees are still so young, when will they grow up?" ”

"So, do you want to try your hand at becoming a greatsword?" Lu Lu asked, pushing his sunglasses with his hand, blocking most of his expression, "Anyway, your eyes are white, and it makes no difference if you become a half-human, half-demon with silver eyes." ”

Li Huan pondered in his heart, he really wanted to try the warrior surgery, otherwise how could he get the demonic energy, and how could he perceive the "twin goddesses" without the demonic energy?

But why did Lu Lu come out to bring this up?

"Is this it? I don't know much about half-man, half-demon. But it occurred to me that a corrosive potion made from the flesh and blood of demons might be able to leave a mark on the greatsword. Li Huan diverted the topic.

Lu Lu glanced at him and said, "The leader asked me to cooperate with your experiment, and tomorrow I will bring you a piece of demon flesh and blood." The half-human and half-demon thing, you can think about it, in fact, becoming a half-human and half-demon does not mean giving up the identity of a human being, as long as you are still a human at heart, it doesn't matter what you become. ”

Li Huan sent Lu Lu and No.4 away, and thought while packing up the forging workshop.

In fact, what Lu Lu said at the end also referred to them as the men in black themselves. In the comics, the Men in Black show no signs of aging for a hundred years, and according to one of their researchers, Daye, they are also humanoids who have undergone physical transformation.

As for whether he is still human, Lu Lu gave his opinion.

It's a pity that these men in black who came to the island for experiments for "lofty ideals" did not instill this point of view in the big swordsmen, and purged and crusaded against them on the grounds that the awakened half-humans and half-demons were no longer humans.

This is understandable from the point of view of controlling the progress and scale of the experiment, but it does not prevent it from being one of the evidence of the evil done by the man in black.

After Li Huan got the demon's flesh and blood, he looked at the purple flesh in front of him twitched slightly, and couldn't help but sigh at the demon's powerful vitality.

He reached out and some silver filaments flowed from between his fingers, wrapping around the pieces of flesh.

"If you find a high-energy substance, do you absorb it?" The Nano Armor Intelligence System sends out a prompt.

Sure enough, Li Huan said in his heart, when he splashed demon blood on his body before, he noticed that the nano armor was about to move, and the flesh and blood of this strange creature could indeed provide energy for the activated nano biochemical suit.

After absorbing an entire piece of demon flesh, the nanoarmor has a recharge rate of 0.02%.

There must be a secret to this armor, and the flesh and blood of a great sword warrior can only provide it with such a tiny amount of energy, and it is unbelievable to say that it has no backhand.

In the future, you must be careful when encountering players who give away this armor.

A few days later, Li Huan showed Lu Lu a clay pot with some red liquid in it, and he said, "This is the final solution I configured, I call it the essence of the devil, and it only takes a little bit to engrave a sword mark on the big sword." ”

The presentation took place in the organization's chamber, in front of all the men in black and the leader Lemoto.

Li Huan picked up a brand-new big sword, and then dipped a sharpened wooden stick in a little "Demon Essence", and drew a small cross on the side of the big sword.

After waiting for about half a day, he showed the cross to everyone.

I saw that a red cross mark appeared on the sword body, which could not leave any traces of dye, and I couldn't feel any bumps when I touched it with my hand, and it wouldn't fall off if I scratched it with a sharp blade.

Lemoto was curious about how this worked.

Li Huan explained with a little pleasure: "It's very simple, in fact, this solution corrodes the material of the big sword, if it is a small amount, it can only corrode a little bit of dents, and just let the solution itself condense after filling the dents, it looks like a painting." ”

The people in black couldn't help but whisper suddenly, and Li Huan's ears could hear that they were in various "slots" and "how could it be".

Lemoto said: "Quiet! ”

He looked at Li Huan and said, "I see, I don't know what the formula of this solution is?" ”

Li Huan smiled and said: "Actually, this is also something I got out by accident, the main raw materials in it are the flesh and blood of the big sword and demons, I put a lot of additives used in forging, and finally it became like this."

"Don't look at it as a small bottle, as long as you add raw materials to it with a big sword and a hundred kilograms of demon flesh and blood, you can continuously create 'Demon Essence'."

Lemoto nodded, looking at Daye, the scientist in the organization.

Daye thought for a moment and said, "It's really possible, if the additives are only used as catalytics." But Mr. Alaire's whimsy is admirable, and I wonder what is going on in his head. ”

As he said this, Daye also licked the corners of his mouth.

Li Huan couldn't help but feel a chill, he estimated that this Daye was thinking about performing a warrior surgery on him.

Lemoto was in a good mood, and even raised his drooping eyelids slightly in his old age, and said, "Mr. Alaire, you have made a great contribution to our organization. I don't know what reward you want? ”

Li Huan thought for a while and said, "I don't need a reward or anything, I'm already very happy to be able to see so many cute little girls here." ”

He was referring to trainees.

"Hahaha, the little girl is really comfortable." Lemoto laughed, skipping the reward.

In fact, Li Huan had already received the biggest reward, and his solution was not so simple.

If the organization wants to use the solution he made, it must be prepared to be pitted later.

What Li Huan needs most now is actually to get a few more big swords to replace all the nanomaterials on his body.

Then you can run away.
