In this way, it took a full day and a half for Lan Yu to recover, thanks to Gu Yang's blood corpse crystal. And after recovery, what Lan Yu has to do is naturally to take out all the crystals of those blood corpses, so many treasures are placed outside, can Lan Yu rest assured?

There are quite a few blood corpses led by Gu Yang, and there are also thirty or forty blood corpses that have been able to evolve plus the number of mutants, so Lan Yu has dug up a big bag just by digging up the blood corpse crystals.

Back in the temporary room, Lan Yu had two crystals of different colors on the table, one was red, like agate, and the other was white, like white jade.

But Lan Yu knew that these two crystals were not agate and white jade, but a special product, called essence.

According to the previous life, this essence is a treasure that only monsters that are qualified to become kings, and the role of this treasure is to guide the ability to mutate.

With the opening of the brain domain, as long as you absorb enough soul breath, one seal after another will be unlocked, and one ability after another will be enhanced, but it is too simple to be too strong because of this.

So in the previous life, by an inexplicable chance, a survivor fused a piece of essence by mistake, causing his skills to mutate.

The ordinary aura bullet turned into a flame aura bullet, which not only greatly increased its power, but also came with the high temperature effect of the flame. The accident caused a huge sensation, and various survivor forces launched investigations and research, and finally came to the end of the world two and a half years.

One could make the news of the ability mutate and make all the survivors go crazy.

It's just that at that time, the strength of all kinds of monsters who are qualified to become kings is already very strong, even if people know the news, they haven't heard of a few survivors at the bottom of society rushing to take risks and risk death to hunt king-level monsters.

But now it's different, it's the beginning of the end of the world, and people don't even know much about the blood corpse crystal, let alone the essence that is more precious than the crystal.

And now, what Lan Yu has in front of him are two pieces of essence, one is taken out of Gu Yang's head, and the other is taken out of Liu Weishan's head.

"Let's see if you and my abilities work." First take the piece of crimson essence, Lan Yu drips blood, and at the same time close his eyes and look inward, checking his abilities.

He could see that in his first brain domain, the fourth ability, Life Burn, began to emit a violent agitation, and the reaction of the steel fist and instant kick was weaker, which indicated that the Life Burn matched the crimson essence in front of him, and the chance of producing a good mutation would be greater.

Looking at the second brain domain again, Lan Yu found that the Judgment Greatsword was also restless, but its intensity was less than that of life burning.

"It seems that your essence is still a panacea." Lan Yu smiled at the piece of essence, as if he was talking to Gu Yang. "Okay, it's decided, it's going to be used on you."

As he spoke, a burst of white gas erupted from Lan Yu's body, obviously casting a life burn and entering a state of life burning.

"I'd like to see what kind of change you're going to bring to me?" Lan Yu said, picking up the crimson essence and pressing it on his body.

Somehow, when Lan Yu pressed hard into his body, the essence began to dissolve, decreasing little by little, and finally disappeared.

The white qi around Lan Yu's body also shrank, and then exploded violently, turning from white to crimson, and as this red aura burst out, Lan Yu's skin began to turn red, as if there was a fire burning under his skin.

As a result, the surface of Lan Yu's body was like a burning boiler, and it was also erupting with crimson steam.

"Yes, it's good." Lan Yu waved his body and found that his body had become more flexible, and at the same time, he could also control the red hot gas erupting from around him in every move, and he could completely use that hot gas as a bullet in a short distance, and it would not consume too much physical strength.

"What if you use a steel fist?" Lan Yu was a little moved, but after thinking about it, it was a waste to use any move in this state now, so it was better to save some effort and wait for the bloody corpse to be cut on the way back.

Lifting this state, Lan Yu clearly saw that the fourth ability of his first brain domain had completely changed.

Blood Burning: By burning blood, it brings more energy and bursts out with powerful force, and at the same time, the steam generated by blood burning will turn into high-temperature red steam and be discharged from the body.

"It's not much different from life burning, but if you save money by changing fuel from life force to blood, you can use this state endlessly." Lan Yu's heart was already happy at the moment.

But as he dissipated the burning state of blood, a feeling of dizziness followed, and at the same time, the intense thirst made Lan Yu want to lie on the nearest toilet and drink bitterly.

This is the sequelae of blood burning, anemia and intense thirst, which is a little better than the sequelae of burning life, body aches and weakness.

Finally solved the thirst problem, and Lan Yu felt a little more relaxed. However, for the result obtained by the ability mutation just now, Lan Yu was satisfied from the bottom of his heart.

And then let's look at the role of the second essence.

Distressedly, he dropped a drop of essence blood onto the white crystal, and then looked inside, Lan Yu found that the three awakened abilities in the first brain domain did not move at all, obviously not interested in this essence. Shaking his head in disappointment, Lan Yu shifted his attention to the second brain domain by the way.

To Lan Yu's surprise, the first ability in the second brain domain actually reacted more strongly than ever at this moment, even stronger than the reaction of life burning just now.

What does this mean? This shows that the Judgment Greatsword fits well with the white essence in front of him.

"Let me see what kind of miracle you can bring me?" Lan Yu took out the Judgment Greatsword and fused the white essence with the Greatsword.

This fusion speed is much slower than before, but the reaction during fusion is not as explosive as before. Overall, the fusion was modest.

As the fusion was complete, Lan Yu quickly withdrew the Judgment Greatsword, and then summoned it again.

Suddenly, Lan Yu's eyes lit up, because after fusing the white essence, this ability had become very different from the original.

The first difference is the name, and at this moment the name of the first ability in the second brain domain has changed to Shura's weapon: Judgment and Redemption.

And as Lan Yu summoned it, he turned into two weapons in his hands.

One of them was the jet-black Judgment Greatsword, and it didn't seem to have changed in appearance, but it was generally the same as before. The other was an extremely slender long sword, with a hilt of only one meter and two meters in length, and a width of only two fingers, and a pure white color throughout, in stark contrast to the Judgment Greatsword.

"This is also a mutation?" Lan Yu held one in one hand, a little surprised. Before, it was only possible to summon one Judgment Greatsword, but now it can summon one more Redemption Rappier, and the Greatsword has become a double sword, which should also be called a mutation, and it is still the kind of mutation that changes quite a lot.

But what exactly does this sword of salvation do? Wrapping the spirit in the Salvation Blade, Lan Yu got a message in his mind.

Salvation: Possesses the power of purification, which can dispel evil and save lost souls without harming the body of living beings.

The short introduction made Lan Yu really not know how to complain, this thin sword is completely an accessory to the ruling giant sword! Lan Yu, who had still had great expectations, was already discouraged at the moment, compared to the Ruling Giant Sword, this Redemption Rapier was not at the same level at all, but what was the essence doing, it would cause this kind of mutation, it stands to reason that this should be regarded as a mutation failure.

However, considering that this mutation didn't have much of an impact on his ability, it only gave that ability a small addition, which is also a blessing in misfortune.

After adjusting his mood, Lan Yu walked out of his room and went to Huang Ling's room to find out Huang Ling's current situation.

After two days of recuperation, Huang Ling also woke up from a coma, because of excessive blood loss, she could only lie in bed weakly for the time being. However, she also knew in her heart that she must have been saved by Lan Yu, otherwise it would be impossible to survive. In this regard, Huang Ling can only put this kindness in her heart and wait for the opportunity to repay it in the future.

Although she woke up, the lack of blood in her body made her extremely weak, so that she didn't have enough strength now, so she could only lie lazily on the bed to rest.

Fortunately, there is a bloody corpse Xiaohao guarding by his side. Looking at Xiao Hao lying beside him, Huang Ling liked this obedient child from the bottom of her heart, even if Xiao Hao had become a blood corpse now, and it was a special blood corpse that Lan Yu had never heard of.

"Teacher, are you awake?" After the last battle, Xiao Hao also seemed to have turned on his wisdom, he became a lot more clever, his brain was also flexible, and he spoke smoothly, except for the fact that he still had the characteristics of a bloody corpse on his body, he already had everything that an ordinary student should have.

"Thank you, Hao." Huang Ling expressed her gratitude, which was not only a thank you for Xiao Hao's care in the past few days, but also a thank you for Xiao Hao's fight with Gu Yang for himself when he was fighting with Gu Yang.

"It's ...... Xiaohao ...... What should be done......" Blood Corpse Xiaohao heard Huang Ling's thanks, and immediately became a little shy, and he couldn't speak.

"Hey, are you feeling better?" At this time, Lan Yu pushed the door directly from the outside, and even the step of knocking on the door was saved.

Seeing Lan Yu, the bloody corpse Xiaohao let out a howl from his mouth, if it weren't for Huang Ling watching, maybe he would have rushed out and fought to the death with Lan Yu.

"You're all right?" Huang Ling looked at Lan Yu with some shock, and she had expressed disbelief more than once in her heart, this is simply cheating, they are all seriously injured, how can Lan Yu get better so quickly, and he is still lying on the bed weakly.

"Of course," Lan Yu made a dragon and tiger shape, and then took out a blood corpse crystal from his pocket, "Eat it, with this crystal, you will get better faster." ”

Of course, Huang Ling knew what Lan Yu was in his hand, anyway, his life was saved by Lan Yu, and it was nothing to owe a little.

So he unceremoniously took the blood corpse crystal from Lan Yu's hand, and then stuffed it directly into his mouth, allowing the crystallization to flow into a smooth liquid into his body and recover the injuries in his body.

The blood corpse Xiao Hao next to him swallowed his saliva, he could smell the strong aroma of the blood corpse crystal just now, which was much more fragrant than the ordinary crystal, that is to say, that crystal was an unusual blood corpse crystal.

"Well, when you're well, we'll pack up and head back to the cannery." Lan Yu commanded, and walked out without looking back, as if he hadn't done anything just now.

Of course, he wouldn't say that the blood corpse crystal that Huang Ling swallowed just now was Liu Weishan's blood corpse crystal.
