This brain crystal is obviously not of a low level, at least Hong Yi is the first time he has seen a crimson brain crystal, and the red color is almost as if it is about to drip blood.

Obviously, this thing is much more advanced than the usual white brain crystals.

Hong Yi didn't know its value, but he guessed that it must not be low, Hong Yi put away this piece of crimson brain crystal, and then rummaged through it, but did not find anything valuable.

At this moment, the cigarette fart over there struggled to crawl over, sending a signal to Hong Yi that he was eager to eat.

"You want to eat it?" Hong Yi pointed to the corpse of the ground ratman swordsman, asked the smoke fart, and saw that the latter nodded with great certainty, and immediately nodded in agreement.

Smoke Fart was almost killed by a sword just now, and it was also a lot of hard work, so of course there was no problem in letting it eat the corpse.

With Hong Yi's consent, the smoke fart was very excited, and immediately crawled over and began to devour.

Hong Yi is not interested in watching smoke farts eat, without arrows, the longbow will lose its effect, and now the crisis is still not resolved, Hong Yi needs weapons to defend himself and deal with emergencies.

Of course, the biggest threat comes from the mutants in the mines.

"Are there any other guns?" Hong Yi opened the car door and asked Lu Xiaolu, who nodded hurriedly and pointed to the back seat. Just now she had already collected all the weapons in the car, there was only a rifle, a pistol and a submachine gun, and the submachine gun had been given to Hong Yi just now.

Hong Yi nodded and put down the submachine gun, although the rate of fire of this weapon is fast, but the power is average. He grabbed the rifle before, it was a modified rifle, using a large-caliber steel core bullet, which was very powerful.

"Go to the other car to collect something, the cigarette fart is almost injured, let's get out of here immediately!" After Hong Yi finished speaking, he began to load the rifle, and Lu Xiaolu asked at this time, "Is the smoke fart the giant hunter mutant?" ”

This girl is quite smart.

Hong Yi nodded, Hong Yi obviously didn't want anyone to know about the existence of the smoke fart, but the current situation was a bit special, since Lu Xiaolu had already known about it, Hong Yi was like asking the other party to keep a secret for himself.

"Smoke fart and my thing, I hope you don't tell anyone, can you do it?" Hong Yi stared at Lu Xiaolu at this time and said, it may be that the murderous aura when he fought against the rat man swordsman just now has not completely dissipated, and Lu Xiaolu who watched it was obviously trembling.

"Don't worry, I know, everyone has secrets, and I won't tell anyone, but it would be better if you could let me study the smoke fart." Lu Xiaolu rubbed her white and tender little hands at this time and said, with a look of anticipation and apprehension.

Study?

Hong Yi glanced at Lu Xiaolu, who hurriedly waved his hand: "Don't worry, it's not the kind of research you think, at most it's to collect a little skin and blood samples, by the way, some of my things here may be able to help you." ”

As if remembering something, Lu Xiaolu took off a backpack that was on his back like a treasure and took out a small metal box from it.

There was a small battery on the metal box, with a six-digit password, and after opening it, it was found to be a small refrigerator with some test tubes of different colors.

Lu Xiaolu took out a test tube of light green liquid, and then shook it proudly in front of Hong Yi.

"What is this?" Hong Yi asked, and the latter immediately said: "This is the regeneration potion I researched, cough, of course, this is not for human use, because the raw material used is a virus sample of the prototype, and the human immunity is not immune to the side effects of this agent at all, so it is specially prepared for mutants." ”

Lu Xiaolu explained, and Hong Yi finally understood.

The thing in her hand is poison for humans, but for mutants, it is a medicine with extremely strong medical effects, according to what she said, even if it is a serious injury, as long as the mutant does not die, the injection of this medicine mutant will recover in a short time.

Since there is such a good thing, Hong Yi of course chooses to use it.

The potion was quickly injected into the fart, and within five minutes of the injection, the frightening wound had healed most of the fart.

Seeing this scene, Hong Yi was also dumbfounded, and secretly said that this Lu Xiaolu is not an ordinary person, and he can even study this kind of thing, if the mutant knows that there is such a thing, I am afraid that no matter how much it costs, she will be arrested.

"About this potion, it's also my secret, and you have to keep it secret for me!" After Lu Xiaolu finished injecting the cigarette fart, he said playfully to Chong Hongyi.

Hong Yi nodded, now that the smoke fart has regained his mobility, Hong Yi plans to leave here immediately, at this moment the No. 14 mine is dark, but Hong Yi can feel that there are many mutants peeking at him in the shadows.

"Let's go!"

Hong Yi got into Lu Xiaolu's armored car, started the car, and drove away quickly with one foot on the accelerator, Lu Xiaolu sat in the co-pilot, and the smoke fart was behind the palace.

After Hong Yi left, a mutant came out of the No. 14 mine.

It's that corpse.

At the moment, it stared at the car that had moved away, without any expression on its face, it was a walking corpse, and of course it would not have any expression.

And behind it, the huge pig demon and the bear demon walked out together, and the bear demon still looked like it didn't care about itself, and there seemed to be nothing to make it care.

However, the pig demon looked at the minced meat scattered on the ground, and laughed proudly, and he didn't know what it was laughing at, but in this laughter that was even more terrifying than crying, some low-level walking corpse mutants around him subconsciously took a few steps back.

"Zhang San, the magnet here has been absorbed, we won't come again in the future, don't leave it at that, besides, that human is very interesting, you'd better not touch him, otherwise I'll come and kill you!" issued a warning, and the pig demon's body was filled with a cloud of black gas as black as ink, and the wind was on the ground, and the black gas rolled it and the bear demon, and it turned into a black wind and disappeared without a trace.

The corpse demon smiled noncommittally, glanced at the car that was long gone, and then slowly walked back to Mine Fourteen, escorted by a large number of walking corpse mutants.

In the night, Hong Yi drove directly to a remote valley, found a cave, killed several werewolf mutants that occupied the cave, and then occupied the place.

It is unlikely that they will return to Gathering Place 7 at this time, not to mention that they will encounter a large number of mutants on the way, and even if they go back, Gathering Place 7 will not open a passage for them to enter.

So it's better to find another place to stay.

Checked the cave, there is only one entrance, not much space, but enough for them to rest, the only drawback is that the smell is too strong, of course, now is not the time to pay attention.

"We'll stay here until dawn!" Hong Yi sat directly on the ground while letting the smoke fart guard the entrance of the cave.

Lu Xiaolu nodded, everyone who lives in the gathering place knows that you should never wander in the wild at night, because no one knows what will happen.

It is said that mutants sometimes break out in the mutation frenzy at night, that is, a large number of mutants fall into the riot, they attack any creature they see, and sometimes, there will be fights between mutants, there have been many tragedies in human history, and the experience of blood tells people that they must not go out at night.

The cave fell silent for a moment, and soon, one could hear the roars outside, and sometimes the sound of countless footsteps moving, which was obviously a group of mutants moving.

Lu Xiaolu sat on a flat ground with her legs crossed, listening to the noisy roar outside the cave, but she didn't feel scared and scared.

It is also strange to say that the source of her sense of security, in addition to Hong Yi, actually has that huge cigarette fart.

White Star Level 3, which is within a hundred kilometers of the gathering place, is already a top-level existence, especially the smoke fart obviously belongs to that kind of heavy melee creature, with it guarding the door, unless it actively provokes those large groups of mutants, there will definitely be no danger.

It's just that it's still a mystery as to what Hong Yi relied on to tame this mutant, which makes Lu Xiaolu very curious, but she is not stupid, this kind of question, even if she asks the other party, she won't say it, so it's better not to ask.

At this moment, Hong Yi looked like he was resting, but in fact he was ordering the adjutant Zhi Brain to open the data package in the White Star Level 2 Brain Domain.

This time he accidentally opened the second-level brain domain of Baixing, and Hong Yi was already able to open this second data packet.

Just like the first time, the adjutant brain seemed to restart, and when it was started, Hong Yi saw a prompt, and after opening it, Hong Yi saw a new skill tree.

"Skill Tree Category: Shadowwalker"

"Current Level: 0"

"Reach level 1 to unlock your first exclusive skill, 'White Blade Assassination.'"

Seeing these prompts, Hong Yi couldn't help but have his heart beat faster. In the first data package is the hunter skill tree, which has brought great benefits to Hong Yitian, and at this moment he has obtained a new skill tree type, which of course makes Hong Yi extremely excited.

After careful study, the 'Shadow Walker' skill tree and the 'Hunter' skill tree require experience points to upgrade, but the experience points used for the Shadow Walker's upgrade are obviously more than those of the Hunter, in addition, after obtaining experience points in the future, they must be allocated by themselves, and they can only be blessed with one skill tree.
