"How do you think the mystic crystals were carved?" Vivien didn't answer the question about the spirit directly, but suddenly asked something else.

"Crystallized ......"

Mu You was stunned. The crystallization of secret arts, theoretically, is a harmless magic circuit constructed by using the most primitive and low-level logic of black magic after peeling off the principles of black magic.

It sounds simple, but it's easier said than done to strip the core of the dark arts and extract the purest parts of it.

"The pure black magic circuit is destined to be tried out by people, but black magic is not like ordinary magic, which can be studied at will. Every attempt is a dance on the tip of a knife, accompanied by the risk of losing control after failure. ”

"In this case, the Senling, who has the power to absorb the pollution of black magic, can change its form freely, and can completely simulate the operation of the human magic circuit, is the best choice for the test subject."

"......" Mu You was silent, and when Vivian mentioned this, he already vaguely understood something.

"The forest spirit is a group that has no quarrel with the world, they have a gentle temperament, do not like to fight, the daily work is to absorb all kinds of pollution for the earth, the core of each forest spirit can accommodate a large amount of pollution, and they also have the ability to dissolve pollution, general pollution, when they absorb it, they can be dissolved on the spot, only a very small number of difficult to dissolve pollution will be deposited, such as the pollution of black magic."

Vivien looked at the furious forest spirit in the distance: "And this forest spirit is the most seriously polluted by black magic in their race, because its innate "detoxification" ability is very poor, resulting in its accumulation of black magic pollution much more than that of its own race, and if this continues, it will get out of control sooner or later." And a forest spirit like it that is not capable of being qualified is generally going to die out of control before it gets out of control. ”

"I found it and made an agreement with it, hoping that it would assist me in making secret crystals, as long as I can create secret crystals, I can use the power of crystals to help it channel the pollution deposited in its body, and if this idea can be realized, in the future, it can also solve the problem of elimination within the forest spirit once and for all, and help the entire race survive better."

"It promised?" Mu You asked.

"Yes."

Vivien nodded, "The spirit agreed, and I went through thousands of experiments with it, and finally succeeded in carving a complete circuit of pure black magic." But the countless times out of control have also seriously deepened the pollution level of Senling. Abandoned by the tribe, it came to this marginal land alone, took root here, formed the Black Forest, and set up a labyrinth barrier complex enough to prevent its own black magic from leaking out through the creatures of the forest. ”

"Then Senling handed me the badly damaged core and asked me to clean it up. Everything went according to plan, but ......"

Vivien didn't say any more, but Mu You already knew what was going on.

After the crystallization was made, Vivien and the others discovered that using black magic, in addition to the basic runaway curse, there was also a deeper curse - the curse on human nature! Only the fools who can carry out this plan can ignore the curse of human nature.

As a result, the purification project had to be suspended, and Vivien stayed in the Black Forest before her death, waiting for the arrival of a new generation.

It's a pity that before the heirs grew up, Sen Ling collapsed first......

Thinking about this, Mu You breathed a sigh of relief, but he didn't expect that behind the crystallization of the secret technique, there was actually such a secret.

"You go out, I'll leave it here." Vivien said suddenly.

"Huh? Are you sure? Mu You was stunned.

"Hmm." Vivian nodded: "Use the Reaper Contract to pass on the power to me, you go out to meditate to recover your magic, the next mana consumption will be very intense, you need to stay in a quiet position." ”

"Okay...... now is not the time to waste time, Mu You didn't talk nonsense, and immediately jumped up along the cave above his head, and quickly returned to the ground.

At this time, the location of the original forest hut on the ground has become a collapsed sinkhole, and it is pitch black when you look down.

Mu You sat down more than ten meters away from the sinkhole, and he couldn't get too far away, because he also needed to ensure that the distance between him and Vivian was within 100 meters.

Mu You took out the card of the Death Contract, rubbed it into the crystal, and then released it on the spot

The contract mark, standing on the mark, the power of the two secret magic crystals was suddenly transmitted to Vivien underground.

"Boom!"

Immediately, there was a muffled sound below, followed by the angry howl of the forest spirit, as if a battle had taken place.

Feeling that the natural magic power and ordinary magic power in his body were rapidly consumed, Mu You hurriedly sat down cross-legged, meditating, and at the same time placed various magic recovery potions in front of him, and took drugs at any time.

Sure enough, as Vivian said, the next mana consumption quickly became intense, and the natural mana was okay to say, the black mana concentration here was strong enough, and Mu You still had dozens of black crystals on his body that he had just collected, which could ensure that the supply speed of natural mana was sufficient.

However, the recovery speed of normal magic is a bit out of place. There is also cooling between the same kind of potions, and there are only a few recovery potions available on his body now, and Mu You drinks them almost as soon as he cools down, but he is still stretched.

Mu You couldn't see the scene underground, and he could hear a muffled sound from below that was more intense than the other. From time to time, the earth trembled.

He had expected that the battle would end quickly under such a fierce collision, but the actual process was much longer than expected.

As time passed, Mu You's mana began to decline at a rate visible to the naked eye, and he had used all the recovery methods he could use, but it was impossible to keep going if he couldn't make ends meet.

Two hours later, his mana was completely depleted.

Mu You's spirit began to be a little trance, which was a symptom caused by excessive mental power consumption, but he didn't dare to cut off the magic connection at will, after all, Vivian was in the middle of a battle and could only continue to hold on.

After persisting for another hour, Mu You also completely reached the limit, his head was dizzy, his consciousness ached, and he passed out.

……

When Mu You woke up again, the sky around him was already bright.

The dappled sunlight shone through the gaps in the canopy into the forest, stinging his eyes.

After two or three seconds of soberness, Mu You hurriedly raised his wrist to look at the time, and was suddenly shocked: It was actually three o'clock in the afternoon the next day?

He was in a coma for more than ten hours, and it was even about to close the door!

What about Vivian?

Mu You hurriedly looked around, and there was still the huge sinkhole in front of him, but the noise underground had stopped, and the surroundings were quiet.

Looking at the hint in my mind again, the lifespan consumption of the Reaper Contract had just stopped an hour ago, and it had actually consumed a total of nearly two hundred and eighty years of life!

Coupled with the more than 300 years consumed by opening six additional prop binding slots before, the original lifespan balance of more than 1,000 at this time has actually fallen below the 500 mark, leaving only 443 years.

"It's really fast......"

Mu You also realized what it means to spend money like flowing water at this time, but now he didn't have time to dwell on this, so he immediately jumped out of the cave and went underground to check the situation.

As a result, as soon as he landed, he saw a scene that stirred his heart.

The ground was still as dark as it had been last night.

And in the clearing illuminated by the purple fluorescent stone, a canary fell there, its legs straightened, its body unusually twisted, and under the golden feathers, layers of tumor-like flesh balls grew out wantonly, which was obviously a manifestation of being soaked in black magic and out of control.

"Vivien?!!

Mu You hurriedly rushed over and picked up the canary, but at this time, the canary was already stiff, his feet twitched, his eyes became pitch black, lifeless, and the tumor on his body was still spreading outward little by little.

Vivien, dead?

Mu You's pupils contracted, he really couldn't understand it, he was full of anger before leaving last night, and when he passed, he was already a corpse when he said goodbye?

If it's so dangerous, why didn't they say it earlier, it's a big deal that they gave up the body and just left at that time......

"What kind of expression do you have, as if you want to send me to the end......"

At that moment, a familiar voice sounded in his head.

Mu You was stunned for a moment, and when he looked back, the familiar crow flew from the other end and flew on his shoulder.

"Uh, Vivien? You're alright

……”

When Mu You saw the flying crow, he immediately understood that Vivian's remnant soul did not dissipate, but left the canary and transferred to the crow's body.

"This bird's body is too weak to withstand the pressure of black magic, so I transferred it to the body of the ink crow, which I personally cultivated as a demon, with much higher physical strength, and the talent to automatically absorb ordinary magic power, which can greatly alleviate my dependence on your magic power." Vivien said.

"That's good......" Mu You breathed a sigh of relief, just now he really thought that he would say goodbye to his master and apprentice when he woke up from sleep.

After coming back to his senses, Mu You had time to look around.

At this moment, more than ten meters away in the distance, Sen Ling still maintains an appearance similar to that of an elk, rooted in the fountain of youth, but at this time, Sen Ling no longer has the tyranny of last night, his blood-red eyes have returned to light blue, and the black gas on his body no longer overflows outward, but begins to absorb the black gas from the outside world.

The black qi of the entire Black Forest poured into the ground along the roots of the trees, hovering around the forest spirit, condensing into a gentle whirlpool, and finally submerged into the forest spirit's body.

Even the canary at Mu You's feet, under this absorption, the black magic disorder in his body quickly calmed down, and the tumor flesh on the surface of his body gradually subsided until it returned to its original appearance.

After absorbing all the black magic in the surrounding air, Sen Ling looked up and beckoned, and a branch stretched out from the ground, binding the canary, and then the branch stretched out, sending the canary to Sen Ling's side, and throwing it into the spring water that exuded vitality.

The canary, whose body had been twisted and stiff, after soaking in the spring water for a while, miraculously came back to life, flapping its wings and taking off, throwing off the water droplets of its feathers, and finally flew to rest on the head of the forest spirit, pecking twice on its head, as if venting its anger.

Sen Ling ignored the canary's arrogant move, turned his gaze to Mu You, and looked up and down: "This is the disciple you chose?" ”

Sen Ling spoke, still the kind of mixed sound that seemed to come from the void, but it was much more rational than last night's tyranny.

"Yes."

Vivien nodded: "As you can see, I am no longer capable of fulfilling my promise, so leave the rest to my disciple." ”

"You...... Are you sure? Sen Ling glanced at Mu You again, seeming to be a little hesitant. The core is the foundation of a forest spirit, and obtaining the core of the forest spirit is equivalent to obtaining the power of the forest spirit. Especially its core, it is still a core that is polluted by black magic, and if it falls into the hands of people with evil intentions, it will be a disaster for the world.

"Of course. In your current state, you can't continue to suppress the core, right? Give him your core, and he will help you clean up the contamination of the dark arts. Vivien said.

Hearing this, Sen Ling was silent for a long time before nodding: "Okay, since he is your chosen disciple, I am willing to believe him." ”

With the issuance of these words, in Sen Ling's body, a spherical core that looked like a walnut and was wrapped in a layer of hollow wooden shell, but the inner pitch-black spherical core quietly emerged, and slowly floated towards this side, and finally hovered in front of Mu You.

Mu You reached out and picked up this core, and immediately felt an extremely tyrannical energy tumbling in it, as if desperately trying to pour into his body along his fingers, but fortunately, he blocked the transmission path of magic power in time.

The crystals inside this core looked quite similar in appearance to those black crystals obtained before, but the concentration of black magic in them was countless times richer than the crystals obtained before.

[Contaminated Forest Spirit Heart: The core of the Forest Spirit has the ability to absorb and decompose all kinds of pollution, but the decomposition capacity and capacity have an upper limit, and it will get out of control after exceeding the upper limit of accommodation. Currently accommodated pollution: 99.8%. 】

&.8%…… Sure enough, it was already on the verge of exploding.

Vivian's action last night probably didn't defeat Sen Ling head-on, but helped Sen Ling dredge out some of the pollution and bring it back to its senses.

"Young man, my core is handed over to you, please be sure to keep it safe and not fall into the hands of others. If you can reduce the pollution of the core by more than 10% within a year, it proves that you have the ability to help the forest spirits, and I will give you this spring of long-term symbiosis with me as a reward. Senling's illusory voice rang in his ears.

with this

At the same time, a prompt appeared in Mu You's mind at the right time.

[Trigger the hidden quest "Sen Ling's Mission": Within one year, clean up more than 10% of the contaminated core of the forest spirit, and do not hand over the heart of the forest spirit to others on the way.]

Reward: Fountain of Youth. 】

[Do you accept it?] 】

A year, that's still a long-term task......

"Okay, I accept."

Mu You nodded without much hesitation and responded to Senling's commission.

Not to mention that there are enough rich rewards waiting for him, even if there is no reward, this is also the responsibility owed by Vivian, since he, a disciple, has inherited Vivian's inheritance, he is naturally obliged to help her fulfill the promise she made during her lifetime.

"What about you? What do you do next? Vivien then looked at Sen Ling and asked.

"I've been found and need to be transferred."

After handing over the core and letting go of the burden, Senling's voice seemed to become much more relieved: "I may go back to the clan to have a look, or maybe I will find another quiet place and wait for your results." ”

"As for the Black Forest...... It was meant to prevent me from spilling out the black magic when I lost control, but now, there is no need for it to exist, so let it be reborn in the fire. ”

With Senling's words, the roots of the root system connected to the top soil layer of its body broke, and the roots in those soil layers quietly ignited flames, and the flames quickly spread along the well-developed root network underground.

The temperature in the entire crypt quickly increased.

"Have you seen who harmed you?" Vivien hastened to ask.

"Nope." Sen Ling shook his head: "The other party is very cautious, but through the perspective of the plants outside the forest, I vaguely saw a person wearing church decorations passing by, and the most conspicuous feature is a white cross in the other party's hand......"

It's actually the church people's ghosts?

Mu You was surprised, aren't all churches believing in the Holy Light? Are they also interested in the dark arts?

However, if the mastermind behind the scenes is really the church, those residents infected with black magic can explain it, the church, it is not an exaggeration to say that it is a pyramid scheme, what it is best at is brainwashing.

At this time, the shackles on the stake in the distance had been automatically lifted, and Vivien's body lost its restraints and fell down, entangled in the rattan of the forest spirit, and sent to Mu You.

"Let's go......"

Seeing Mu You take Vivian's body, Sen Ling waved his arm, and the huge wooden palm lifted the two of them up, and they were sent back to the ground in the blink of an eye.

At this time, the Black Forest was already burning with fires, and a hot wave swept by, accompanied by the wails of living creatures, burning all living and dead things in the forest.

"What will happen to this land in the future?" Mu You asked. This forest nurtured by Sen Ling himself, although it is impregnated with black magic, but there are actually many other ways to deal with it, and Sen Ling actually destroyed it in the sea of fire without hesitation, and the determination he showed made him a little surprised.

"Even if the remains of the dark magic are burned, the remaining dark magic in the land will not fade so easily, and in a short time, it will become a polluted area that cannot be set foot on by living creatures until the pollution is gone. This process may take a long time, but it is only for the lifespan of living beings, for the forest spirits, and for the entire astral spirit realm, it is just a flick of the fingers. Vivien said.

Mu You nodded.

The power of the forest spirit is not only life and growth, but also decay and death, to be precise, it is the messenger of the balance of nature, the cycle of life and death, the alternation of the new and the old, the wildfire is inexhaustible, the spring breeze blows and grows, and in the near future, new shoots will emerge here and revive into a new forest.

The fire became more and more vigorous, the heat continued to sweep, and Mu You didn't have time to stop any longer, so he hurriedly set up a teleportation array on the ground and teleported to the tomb of Misty Mountain.

Then he went all the way to the secret room on the top of the tomb, opened the coffin in the center of the secret room that sealed the body of Grandma Lin Xue, and stored Vivian's body in it.

The coffin was not spacious, but it was enough to house the remains of two women.

Vivien looked at the two bodies in the coffin, one young and the other old, and couldn't help but think of the two of them and sighed with a little emotion.

"Let's go back."

"Okay."

……

An hour later, Mu You returned to the door of the Shang Alliance before closing.

The steward who led Mu You into the door before had been waiting behind the door early, and when he saw Mu You, he hurriedly greeted him through the door: "Mr. Mu You, you are back!" ”

The steward wiped his sweat, and the other ninety-seven people who entered the door at this moment all turned back more than half an hour in advance, leaving only Mu You, who had not returned for a long time, which also scared him enough, after all, it was someone sent by the Abnormal Investigation Bureau, and he had to enter the door from them, but he couldn't come back in the end, which was not a trivial matter.

Fortunately, Mu You still returned at the last moment, which made the few people waiting at the door very relieved.

"I've been waiting."

Mu You also said hello apologetically, he didn't expect to fall into a coma in the Black Forest, resulting in a late return.

When he came to the door, Mu You took out the fish tank and other items in his backpack and moved them through the door one by one.

Several members of Lin Hai's team hadn't left at this time, and they came in one after another to help carry it.

"Master, you fry...... Is it going to be sold in your store? Lin Hai looked at the magic fish in the fish tank, and looked at Mu You with some curiosity.

He knew that Mu Youjia opened a pet shop, and at this time, he deliberately transported these magical fish fry back to Earth, which immediately made Lin Hai realize that this might be something to be bred and sold.

"yes."

Mu You nodded: "After a while, my pet store will reopen, and some magical creatures in the Star Spirit Realm will be sold at that time, if you have needs, you can come and see it then, the address is the Strange Pet Store on Xiangjiang Road, K City......"

Mu You took the opportunity to advertise.

"Good!"

"No problem."

"Be sure to check it out when the time comes......"

……

At this time, there were many members of the business alliance who had not left yet, and it was very face-saving when they heard the words, whether they were interested or not, they politely agreed.

Lin Hai's eyes lit up after hearing this, and he hurriedly asked, "Master, do you have chocobos for sale there?" ”

His previous experience in the Elven Forest had already made him hooked on a chocobo ride, and he wanted to experience it again.

"Chocobos are not for sale, but you can ride them on the spot and charge by the time."

Mu You said: "In addition to chocobos, there are other more cherished magical animals, such as mandrakes, tree people, evil women birds, etc., which are not for sale, but can be visited and fed on site." ”

Mu You has already thought about it, and when the magic pet store opens, it will be divided into two parts, one is a normal pet sales store. One is a museum-like zoo-like ticket, offering the opportunity to get up close and personal with the more precious magical creatures. The biggest problem with this exhibition model is that it requires a huge space, but in today's era, there is space for backpacks, and the space is not a problem at all.

"Oh? That's a lot of fun! When the master opens, remember to call me, I will definitely go to the show! Lin Hai was immediately moved after hearing this.

The others were the same, they all looked at it with some surprise when they heard the words, and secretly wrote down the address left by Mu You just now, saying that they would go to the party when the time came.

A shop for magical creatures, a novelty that has never been seen on Earth. If most of the people just now were politely agreeing for the sake of the members of the ally forces, but at this moment, they are really interested.

During a recent meeting, I turned off the comments and character cards, and only I can see the comments after the 15th.
