This brain crystal is obviously of not low level. At least it was the first time that Hong Yi saw a red brain crystal. The red color seemed to be about to drip.

Obviously, this thing is much more advanced than the white brain crystal that is commonly seen.

Hong Yi didn't know its value, but he guessed that it must be not low. Hong Yi put away this red brain crystal and searched it again, but found nothing valuable.

At this moment, the smoke farts over there struggled to crawl over, sending Hong Yi a signal of desire to eat.

"You want to eat it?" Hong Yi pointed to the corpse of the rat swordsman on the ground, asked Yanbi. Seeing the latter nodded with great certainty, he immediately nodded in agreement.

Yanbi was almost killed by a sword just now, and he worked hard and made great contributions. Of course, there was no problem with letting it eat the corpse.

With Hong Yi's consent, Yanba was very excited and immediately crawled over and started to swallow.

Hong Yi was not interested in eating when he was smoking butt. Without arrows, the longbow lost its effect. Now the crisis has not been resolved. Hong Yi needs weapons to defend himself and deal with emergencies.

Of course, the biggest threat comes from the mutations in the mine.

"Are there any other guns?" Hong Yi opened the car door and asked Lu Xiaolu. The latter nodded quickly and pointed to the back seat. She had just collected the weapons in the car, and there was only one rifle, a pistol and a submachine gun, and the submachine gun had been given to Hong Yi just now.

Hong Yi nodded and lowered the submachine gun. Although this weapon fired at a fast rate, it was average. He grabbed the rifle before. This was a modified rifle, which used a large-caliber steel core bullet, which was very powerful.

"Go to other cars to collect things. The smokesticks are almost injured and we will leave here immediately!" After Hong Yi said that, he began to load the rifle, and Lu Xiaolu asked at this time: "Is the smokesticks 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 cigarette farts, but the situation is a bit special. Since Lu Xiaolu has already known it, Hong Yi is like asking the other party to keep a secret for him.

"I hope you don't tell anyone about Yanbi and me. Can you do it?" Hong Yi stared at Lu Xiaolu at this time and said. Maybe the murderous aura when he was fighting with the Rat Man Swordsman just now had not completely dissipated, and Lu Xiaolu obviously shivered.

"Don't worry, I understand, everyone has secrets, I won't tell anyone, but it would be even better if you can ask me to study the smoke fart." Lu Xiaolu said with her white and tender little hands at this time, with expectation and nervousness on her face.

Research?

Hong Yi glanced at Lu Xiaolu, and the latter waved his hand quickly: "Don't worry, it's not the kind of research you think, at most it's just to collect some skin and blood specimens. By the way, some of my things here may help you."

As if he remembered something, Lu Xiaolu took off a backpack that looked like a treasure, and took out a small metal box from it.

There is actually a small battery on this metal box, which uses a six-digit password. After opening it, I found that it was a small refrigeration box 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 agent I have developed. Cough, of course, this is not for human use, because the raw materials used are virus samples from the prototype, and human immune ability cannot be 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.

What she has in her hands is poison to humans, but for mutations, it is a potion with extremely strong medical effects. According to what she said, even if it is severely injured, as long as the mutation does not die, the mutation will recover in a short time when injected with this potion.

Since there is such a good thing, Hong Yi certainly chose to use it.

This potion was quickly injected with the smoke fart, and just five minutes after the injection of the potion, most of the terrifying wounds of the smoke fart healed.

Seeing this scene, Hong Yi was also stunned and thought that Lu Xiaolu was not an ordinary person, and she could even study such things. If the mutant knew that there was such a thing, she would probably have to tell her to capture it no matter how much the price it cost.

"This kind of medicine is also my secret, and you must keep it a secret for me!" After Lu Xiaolu finished injecting the cigarette butt, she said playfully towards Hong Yi.

Hong Yi nodded. Now the smoke fart has recovered its power of movement. Hong Yi planned to leave here immediately. At this moment, the No. 14 mine cave was pitch black, but Hong Yi could feel that there were many mutants peeking at him in the shadow.

"Walk!"

Hong Yi got into Lu Xiaolu's armored vehicle, started the car, and quickly drove away with a throttle. Lu Xiaolu was sitting in the passenger seat, and the smoke was in the back of the palace.

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

It was that corpse monster.

At this moment, it stared at the car that had been away from it, with no expression on its face. It was a zombie, and of course it would not have any expression.

Behind it, the huge pig demon and the bear demon walked out together. The bear demon still looked unrelated, and there seemed to be nothing that could make it care about.

However, the pig demon looked at the minced meat scattered on the ground and laughed proudly. He didn't know what it was laughing at. But in the midst of this terrifying laughter than crying, some low-level zombie mutants around subconsciously took a few steps back.

"Zhang San, the magnet here has been absorbed, and we will not come again in the future. Let's leave here. In addition, that human being is very interesting. You'd better not touch him, otherwise I'll kill you!" A warning was issued, and a ball of black air filled with ink as black as black air. The wind blew from the ground. The black air rolled it and the bear demon, and it turned into a black wind and disappeared without a trace.

The corpse demon smiled unanimously, took a look at the car that had been nowhere to be seen, and then slowly walked back to the No. 14 Mine Cave under the escort of a large number of corpses.

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

It is unlikely that they will return to the No. 7 gathering place at this time. Not to mention that they will encounter a large number of mutants on the way, even if they go back, the No. 7 gathering place will not open the passage for them to enter.

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

I checked the cave and found that there was only one entrance and exit, and the space was not large, but it was enough for them to rest. The only disadvantage was that the taste was too heavy. Of course, it was not the time to pay attention to it now.

"We'll stay here until dawn!" Hong Yi sat directly on the ground, and at the same time let Yanba guard the entrance of the cave.

Lu Xiaolu nodded. Everyone living in the gathering place knew that you should never hang out in the wild at night, because no one knew what would happen.

It is said that mutations sometimes burst into mutation frenzy at night, that is, a large number of mutations fall into Taoist riots. They attack any creature they see. Sometimes, there will be fighting between mutations. There have been many tragedies in human history. Blood experience tells people that they must not go out at night.

The cave suddenly became quiet, and soon, you could hear roars coming from outside, and sometimes you could hear countless steps moving, which was obviously a group of mutants moving.

Lu Xiaolu sat on a flat ground with her legs in her arms, listening to the noisy roar outside the cave, but she didn't feel afraid or afraid.

It's strange that in addition to Hong Yi, there is also the huge smoke fart in her sense of security.

The third level of the White Star, which is already a top-notch within a range of 100 kilometers around the gathering place, especially the Smoke Flame is obviously a heavy melee creature. If it guards the goal, it will definitely not be in danger unless it proactively provokes those large groups of mutants.

However, it is still a mystery about what Hong Yi uses to tame this mutant, which makes Lu Xiaolu very curious, but she is not stupid. She is afraid that even if she asks the other party, she won’t tell her this kind of question, so it’s better not to ask.

At this moment, Hong Yi seemed to be resting on the outside, but in fact he was ordering the adjutant Zhizhu to open the data packet in the second-level brain domain of Baixing.

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

Just like the first time, the adjutant's intelligence brain seemed to restart. When it was started, Hong Yi saw the prompt. After opening it, Hong Yi saw a new skill tree.

"Skill Tree Category: Shadowwalker"

“Current level: 0”

"According to level 1, you can unlock the first exclusive skill 'Ship-Blade Assassination'."

Seeing these prompts, Hong Yi couldn't help but his heart beat faster. The first data packet was the hunter skill tree, which had already brought Hong Yi great benefits. At this moment, he obtained a new skill tree type, which of course made Hong Yi extremely excited.

After careful study, the "Shadow Walker" skill tree, like the "Hunter" skill tree, requires experience value to upgrade, but the experience value used for Shadow Walker upgrade is obviously greater than that of the Hunter. In addition, after obtaining experience value in the future, you must allocate it yourself and can only bless one skill tree.
