Soon, Gervais was in front of the wooden cabinet where the crystal container was placed the day before yesterday.

When he looked towards the crystal container, he found that the material essence liquid, which was originally used to soak the dark attribute demonic beast spar, had actually become completely transparent.

"It's all absorbed by this dark attribute Monster Crystal, right?"

"It's really unusual, I've never heard of the Demonic Beast Crystal absorbing the essence of materials such as potion plants before."

Gervais muttered a few words, then fished out the Warcraft Crystal from the crystal container, and then went directly to the cultivation room!

After coming to the cultivation room and sitting down, Gervais didn't even think about it, he simply opened the system panel, and then exchanged it for a green kiwi fruit with his backhand.

Since there was a lesson about the depletion of mental power, Gervais can be regarded as a wise man, and he should be on guard in advance and be prepared.

Especially today, I have to carry out mental power stripping and cutting, and it would be a tragedy if I accidentally became an idiot.

After exchanging the green kiwifruit, Gervais put the black monster spar in front of him, then closed his eyes and began to concentrate on sensing and mobilizing his spiritual power.

According to the method recorded by the Wizard Neam, before cutting the spiritual power, it is best to merge the message you want to convey into that spiritual power.

This message will become the core of the heart of the undead, and the dark creatures who possess it will act according to this principle when they do not receive valid commands.

Of course, Gervais doesn't need to import information, the heart of the dead is still valid, and the dark creatures with the heart of the dead will still be loyal to him and will never betray him.

However, after that, the thinking logic of the dark creatures will be carried out according to the planned learning of the day after tomorrow.

Gervais wasn't quite sure how much of a difference the two would make after doing so, but he was ready to give it a try.

For example, infuse the heart of the dead with simple information such as calling oneself.

Soon, Gervais was done with the matter of entering the information within the mental power.

The information he entered was very simple, that is, when he saw himself, he knelt down on one knee and shouted "My King!"

The other is the direction that Gervais hopes for the development direction of his summoning servant, that is, he hopes that it will continue to grow stronger and clear all enemies for Gervais.

Once he was sure that nothing else was missing, Gervais moved on to the next most important step.

Cutting mental power may be very light, but it is extremely troublesome to actually operate.

Because spiritual power cannot be seen or touched, it only exists in Gervais's own mental senses, and naturally it cannot be cut with any knife.

And the real way to separate the spiritual power is actually to tear, just like tearing a strip of cloth, tearing a piece of paper, pulling it to both ends in different directions, and finally splitting it into two.

And what Gervais has to do now is exactly that, he needs to do two things, and then manipulate his mental power to carefully pull in different directions, stripping it out of his mind.

"Here we go!"

Gervais took a deep breath, and then began to use his mind to manipulate a few tenths of his mental power to stretch in the opposite direction from the rest of his own spirit.

"Shhh

And the moment Gervais really started to pull, he suddenly gasped, it felt like his head was hit hard by a sledgehammer with his helmet on his head.

If he hadn't been mentally prepared for a long time, it is estimated that he would have to lie down this time.

"Come again!"

Holding back the pain in his head, Gervais continued to exert his strength, and as he continued to tear, the cold sweat on his forehead had already broken out.

Gervais's mental power has become much tougher than ordinary people because of taking the green kiwifruit, but this also makes it more difficult and painful for him to divide his mental power at this time than others.

However, for the sake of the heart of the undead, Gervais still gritted his teeth and insisted.

As he slowly manipulated his spiritual power and pulled carefully, a small gap finally appeared in his spiritual power.

Seeing this, Gervais did not dare to relax his vigilance, but became more cautious.

Pulling mental power is like pulling paper, and if the strength is small, it is useless.

If the force is too strong, it is likely to be torn and pulled, which will directly make the direction and scale of the crack uncontrollable, and it is likely to lead to the scrapping of the whole paper.

And this is the case with Gervais at this time, if you pull too hard, the direction of the tear may change, and it will directly extend to the spiritual power of Gervais's body, which is the danger of cutting the spiritual power.

If the paper is torn, you can replace it with another one, but if your mental power is damaged, you will really become an idiot, and you will only be the kind of Abba Aba.

So in order to avoid becoming like that, even if his head hurts badly, Gervais only dares to come gently.

As time passed, the small gap turned into a large gap, and because of Gervais's care, the fracture zone of spiritual power was also very complete.

"It's coming! Soon! ”

Although his head seemed to have been trampled on by a divine beast, Gervais was extremely excited, as long as this last bit of adhesion was torn apart, then the heart of the undead would be safe.

Wave!

Finally, with Gervais's unremitting efforts, he seemed to hear a crisp cracking sound in his head, and he finally succeeded in stripping a small piece of his spiritual power.

"Whew! It's finally a success! ”

Gervais breathed a long sigh of relief, and the pain in his head immediately subsided the moment the peeling was successful.

Then, Gervais quickly injected the small piece of spiritual power that had just been stripped off into the demonic beast spar in front of him.

Strange to say, when Gervais's spiritual power touched this dark attribute monster crystal, he was immediately sucked into it.

"That's it! Ha ha! I'm a genius, I'm probably the only genius other than Wizard Neam who has concocted the heart of the dead! ”

Gervais's excited cheers resounded through the training room, and he was indeed very accomplished at this moment.

He was sure that there were few people in the Sacred Continent who dared to do such a thing as cutting and stripping spiritual power.

"Now, it's time to verify the results!"

Thinking about it, Gervais quickly used the summoning technique.

Previously, Gervais had specially exchanged for green kiwifruit just in case, but he didn't expect everything to go so smoothly, and his spiritual power was not lost at all.

At this time, his mental power was only a few tenths less than before, but this was not a matter for Gervais at all, and he could make up for it with kiwifruit.

As Gervais finished casting his spell, a dark hole appeared in the ground in front of him, and a skeleton was slowly crawling out of the hole.

Since it was an experiment, Gervais was definitely reluctant to test his Skeleton Warhorse Nightmare, after all, Skeleton Warhorses were very rare.

And if you take an ordinary gray skeleton soldier, Gervais feels a little lost.

So he's ready to give it a try with his only green skeleton.

A moment later, Gervais's only green skeleton was standing quietly in front of him, the green soul in its eyes not beating.

"Come, eat this heart of the dead! It may be your chance, or it may make you finished, it all depends on your own creation! ”

Handed the Heart of the Dead to the skeleton soldier, Gervais muttered to it.

At this time, Gervais was also a little nervous, and now it was time to verify the results that he could get by spending so much money and energy.

And now he has added his only green skeleton soldier, if there is a pot of ends, it will be a loss to grandma's house.

Although the skeleton soldier was not conscious and did not know what his own master was nervous about, after receiving Gervais's command, it still stretched out its slightly pale green hand bone and took the heart of the dead handed by Gervais.

After receiving the heart of the undead, the green skeleton did not delay, and directly stuffed the gray-black demonic beast spar into its mouth.

Gervais then stared intently at the green skeleton and began to wait for the result.

The green skeleton did not chew after stuffing the Monster Crystal into its mouth, and the Monster Crystal did not fall out of its hollow jaw, but was wrapped in the green soul fire in its skull the moment it entered its mouth.

Just after the green soul fire enveloped the heart of the undead, the mutation also began to appear.

It was only two or three seconds later, and the soul fire in the green skull's skull changed.

The original pale green soul fire slowly rose to gray black, and this gray black became thicker and thicker as time passed, slowly dyeing the soul fire of the green skeleton soldier black.

And at this time, the green skeleton soldier also moved, and it was motionless, and it actually raised its white arms to cover its head without Gervais's order, as if there was endless pain in its skull.

Click, click!

Perhaps it was really painful to the extreme, and the lower teeth of the green skeleton kept colliding and making a clicking sound.

"Could it be that this heart of the dead is fake? Wizard Neham shouldn't be so boring! ”

Seeing this, Gervais couldn't help but wonder in his heart if the recipe for the heart of the dead was fake.

However, Gervais's thoughts didn't last long, because it was only a few seconds later that the soul fire in the green skeleton's skull changed again.

The original gray-black color of the soul fire began to slowly dissipate, as if it had been burned out by the green soul fire.

At this time, the green skeleton also stopped holding its head, and the symptoms of mouth trembling disappeared without a trace.

Wave!

Suddenly, the soul fire in the green skull's skull made a wave, and then as if it had been doused with gasoline in an instant, the fire was victorious.

Gervais only felt a sudden flower in front of him, and he couldn't look directly at the fire, but this state only lasted for a moment, and he recovered after a while.

And when Gervais looked at the green skeleton again, the green skeleton's soul fire had also returned to normal, as if it had been a hallucination before.

"Well, no, the green skeleton's soul fire seems to be a little more vigorous than before!"

However, Gervais still sensed the clue from the green skeleton's body, because the green skeleton's soul fire was obviously a little stronger than before.

Just when Gervais was speculating about why the green skeleton soldier's soul fire was a little more vigorous than before, he suddenly saw the skeleton soldier in front of him move again.

I saw that the green skeleton soldier faced this Gervais, and simply knelt down neatly.

Then the green skeleton soldier lowered his head, held the hilt of the sword at his waist with his left hand, and bent his right arm into a fist and pounded it into his chest, which turned out to be a salute of allegiance to Gervais.

"Click! Click! ”

"Damn, it really worked!"

When he saw the Green Skeleton's series of moves, Gervais knew that the undead heart he had configured had succeeded.

Because this is the message he had injected into his spiritual power before, how to salute himself.

If it weren't for the fact that the skeleton soldier couldn't speak, then its click would have been 'Seen my king'.

"Get up!"

Gervais's face couldn't stop excited, and he commanded the green skeleton soldier.

The next moment, the half-kneeling green skeleton soldier first bent down slightly and continued to salute before standing up.

And today's green skeleton soldier standing in front of Gervais is no longer the same posture as before, it actually knows how to bow its head slightly, showing respect for Gervais.

"Excellent! Now that you have a sense of autonomy, I'll give you a code name! ”

"You just call Number One! Number one of my Death Legion! Death One! Well, that's it! ”

Gervais didn't bother too much, and he was going to summon more skeleton soldiers in the future, so he directly used the code name instead of the name, which was also convenient for his command in the future.

"Click! Click! ”

Skeleton soldiers with self-consciousness naturally know how to be grateful, so when Gervais named it, Number One immediately responded!

"That's it! In that case, you should go back first! If possible, you'd better practice fighting in the Dark World, but be sure to save yourself! ”

Gervais looked at Death One again for a moment before sending him back to the Dark World!

And I told it a few more words before sending it back.

Although the heart of the dead has made One self-conscious, he has a little wisdom.

However, wisdom is not achieved overnight, and it also needs to be accumulated through the acquisition of No. 1.

Therefore, Gervais hopes that No. 1 can continue to learn and accumulate in the dark world, so that when encountering battles in the future, he can know how to adapt to changes like the skeleton mage they met at the beginning.

After determining that the method of configuring the Undead Heart was true and effective, Gervais immediately began to pull out another material for the Undead Heart from the spatial ring.

He is ready to continue to make a heart of the undead and use it for his nightmares, and then the nightmare will become a real nightmare.
