"How do you think the secret crystal is carved?" Vivian did not directly answer the question about the forest spirit, but suddenly asked something else.

"Crystal..."

Mu You was startled. The secret crystallization is theoretically a harmless magic circuit constructed by stripping away the principles of black magic and using the most primitive and lowest logic of black magic.

This statement sounds very simple, but to peel off the core of black magic and extract the purest part, this process is not easy.

"Pure black magic circuits are destined to require people to try one stroke at a time, but black magic is not like ordinary magic, which can be studied at will. Every attempt is dancing on the tip of the knife, accompanied by failure.

The risk of losing control later.”

"In this case, a forest spirit that has the power to absorb black magic pollution, can freely change forms, and can completely simulate the operation of the human body's magic circuit is the best choice for the test subject."

"..." Mu You was silent. When Vivian mentioned this at this time, he already vaguely understood something.

"Forest spirits are a group of people who live in peace with the world. They have a gentle temperament and don't like fighting. Their daily job is to absorb all kinds of pollution from the earth. The core of each forest spirit can accommodate massive amounts of pollution, and they also have the ability to digest it themselves.

The ability to pollute, general pollution, can be digested on the spot when they are absorbed. Only a very small amount of pollution that is difficult to digest will be deposited, such as the pollution of black magic."

Vivian looked at the violent forest spirit in the distance: "And this forest spirit is the one most polluted by black magic among their tribe. Because its natural "detoxification" ability is very poor, the accumulated black magic pollution is more than

There are many more of its kind, and sooner or later it will lose control if this continues. And a forest spirit with unqualified abilities like it will usually self-destruct before it loses control."

"I found it and made an agreement with it, hoping that it would help me create secret crystals. As long as I can create secret crystals, I can use the power of the crystals to help it remove the pollution accumulated in the body. And if this idea can be realized, in the future

It can also solve the problem of elimination within the forest once and for all, helping the entire group survive better."

"Did it agree?" Mu You asked.

"Yes."

Vivian nodded: "The forest spirit agreed. After thousands of experiments with it, I finally succeeded in carving out a complete circuit of pure black magic. However, countless times of loss of control also seriously deepened the relationship between the forest spirit and the forest spirit.

The degree of pollution. It was abandoned by the ethnic group and came to this edge land alone, where it took root and formed a black forest. It also set up a complex labyrinth barrier to prevent itself from being invaded by black magic in the future.

Leaked through the creatures in the forest."

"Then the forest spirit handed over the severely damaged core to me and asked me to help clean it up. Everything originally went according to plan, but..."

Vivian didn't say anything further, but Mu You already knew what happened.

After the crystal was created, Vivian and the others discovered that using black magic, in addition to the basic out-of-control curse, there was also a deeper curse - a curse on human nature! The only ones who can execute this plan are fools who can ignore the curse of human nature.

Therefore, the purification plan had to be suspended midway, and Vivian stayed in the Black Forest before her death, waiting for the arrival of a new generation of successors.

It's a pity that the forest collapsed before the successors could grow up...

After thinking about this, Mu You breathed a sigh of relief. He didn't expect that there was such a secret behind the secret crystallization.

"You go out and leave this place to me." Vivian suddenly said.

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

"Yes." Vivian nodded: "Use the Death Contract to give me your power. You go out and meditate to restore your magic power. The subsequent magic power consumption will be very intense. You need to stay in a quiet place."

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

At this time, the location of the forest hut on the ground had turned into a collapsed sinkhole, and it was pitch black when you looked down.

Mu You sat down a dozen meters away from the sinkhole. He couldn't stay too far away because he also needed to ensure that the distance between him and Vivian was within a hundred meters.

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

Standing on the contract mark, the power of the two secret crystals was immediately transmitted to Vivian underground.

"Boom!"

There was a muffled sound immediately below, followed by the roar of the forest spirit, and it seemed that a battle had already occurred.

Feeling that the natural magic power and ordinary magic power in his body were being depleted rapidly, Mu You hurriedly sat down cross-legged, meditating while placing various magic power recovery potions in front of him, ready to take them at any time.

Sure enough, as Vivian said, the subsequent magic power consumption quickly became intense. The natural magic power was okay, the concentration of black magic power here was strong enough, and Mu You still had dozens of black crystals that he had just collected, which could guarantee

The supply speed of natural magic power is sufficient.

But the recovery speed of ordinary magic can't keep up. The same kind of magic potion also has a cooling effect. There are only a few recovery potions available for him now. Mu You almost drinks it as soon as it cools down, but he is still short of resources.

Mu You couldn't see the scene in the ground below, so he heard a muffled sound coming from below that was more intense than the previous one. The ground trembled from time to time.

He thought that with such a fierce collision, the battle would end quickly, but the actual process turned out to be much longer than imagined.

As time went by, Mu You's magic value began to decline at a speed visible to the naked eye. He had used all the recovery methods at his disposal, but it was impossible to persist forever if he could not make ends meet.

Two hours later, his magic power was completely exhausted.

Mu You's spirit began to feel a little dazed, which was a symptom caused by excessive consumption of mental power, but he did not 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.

This chapter is not over yet, please click on the next page to continue reading!

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

……

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

The dappled sunlight was projected into the forest through the gaps in the tree crowns, making his eyes sting.

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

He actually fell into a coma for more than ten hours, and it was even close to closing time!

Where is 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 surrounding area was quiet.

I looked at the reminder in my mind again. The life span consumption of the Death Contract had just stopped an hour ago. It actually consumed a total of nearly two hundred and eighty years of life!

Coupled with the more than 300 years spent on opening six additional prop binding slots, the original life span balance of over 1,000 has actually fallen below the 500 mark, with only 443 years left.

"It's really fast..."

At this time, Mu You finally realized what it means to spend money like running water, but now he had no time to dwell on it and 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 underground is still the same as last night, full of dark purple tones.

And in the open space illuminated by the purple fluorescent stone, a canary lay there, its legs straightened, its body abnormally twisted, and under its golden feathers, layers of tumor-like flesh balls grew wantonly.

It is obviously a sign of being soaked in black magic and losing control.

"Vivian?!!"

Mu You hurriedly rushed over and picked up the canary. However, at this time, the canary's body had stiffened, its feet were twitching, its eyes had turned pitch black, and it was lifeless, but the tumorous flesh on its surface was

It is still spreading outward little by little.

Vivian, dead?

Mu You's pupils shrank, and he really couldn't understand. Before leaving last night, he angrily asked him to leave. After a sleep, he was already a corpse when he saw him again?

If it was so dangerous, why didn't you tell me earlier? In the worst case, they would have abandoned the body and just left at that time...

"What's that expression on your face? It seems like you want to die for me..."

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

Mu You was stunned and looked back, seeing a familiar crow flying from the other side and landing on his shoulder.

"Uh, Vivian? Are you okay?

..."

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

"The body of this bird is too weak to withstand the pressure of black magic, so I transferred it into the body of Mo Crow. Mo Crow is a familiar that I personally cultivated. Its physical strength is much higher, and it can also automatically absorb ordinary magic power.

Your talent can greatly alleviate my dependence on your magic power." Vivian said.

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

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

At this moment, more than ten meters away, the forest spirit still maintains an elk-like appearance, rooted in the fountain of youth, but at this time, the forest spirit no longer has the violence of last night, and its blood-red eyes have returned to light blue.

Color, the black energy all over the body no longer leaks out, but begins to absorb the black energy from the outside world.

The black energy of the entire black forest poured into the ground along the tree roots, hovered around the forest spirit, condensed into a gentle whirlpool, and finally disappeared into the forest spirit's body.

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

After absorbing all the black magic emanating from the surrounding air, the forest spirit looked up and waved. A branch stretched out from the ground and bound the canary. Then the branch stretched and sent the canary to the ground.

The forest spirit is surrounded by spring water exuding vitality.

The canary, whose body was already twisted and stiff, miraculously came to life after soaking in the spring water for a while. It fluttered its wings and took off, shaking off the water droplets on its feathers. Finally, it landed on the head of the forest spirit and headed towards it.

It pecked twice on the head, seemingly venting its anger.

The forest spirit ignored Canary's arrogant behavior, turned to Mu You, and looked him up and down: "Is this the disciple you chose?"

When the forest spirit spoke, it was still the same mixed sound that sounded like it came from the void, but compared to the violence last night, it was much more rational.

"Yes."
