Han Tu sat cross-legged and took out the arm of the long-armed demon ape from earlier. And began to prepare, about the refining of the magic core. In this regard, he really has no experience, so he can only take one step at a time.

Most of the magic cores are stored in the blood of the heart, and they need to be condensed together by special refining techniques to form crystalline balls with special aura, which are called Warcraft cores.

When buying the Broken Arm of the Demon Beast that day, the seller had mentioned that there was something about the existence of the Demon Core. Gibbon apes are a bit different from other monsters in that they rarely store their cores in their arms. And in terms of value, such a magic core will definitely far surpass other magic cores of the same level.

It's just that the method of refining the demon core requires special exercises, and it can only be completed with at least the strength above the foundation building period. Among the sects, there is indeed a service to help extract the magic core. It's just that this fee standard is indeed far more than Han Tu can bear.

Besides, it wasn't a day or two for this broken arm to come to the Dust Slashing Sect, and the time for selling it was definitely not short. If there really is a so-called magic core in it, then how can the others let it stay and be purchased by Han Tu?

But the strange thing is that when he wanted to refine the broken arm and become part of the arm exchange decision, he also encountered some kind of resistance. And a dead thing will have such resistance, maybe there is only one possibility, and that is the existence of a magic core inside.

Gibbon Monkey's Magic Core is mostly used to improve other Demon Cores, or medicinal herb levels. On its own, it doesn't have much value. Because of this, Han Tu had no intention of condensing it in a short time.

However, if it was just to draw the blood out of his arm, it would still be easy for Han Tu, who had learned to control the water.

When learning spells, most immortal cultivators will choose spells that match the exercises, or those that are equivalent to the attributes of the spiritual root. Therefore, only in this way can they use it more handily and avoid attribute conflicts, which will cause unnecessary trouble. In severe cases, it will also affect the foundation.

But the immortal cultivators of the miscellaneous spirit root naturally have no such concerns, and when they use the same spell, they will be more than thirty percent weaker than other immortal cultivators with single spirit root or dual spirit root. But despite this, they also have an extra advantage, that is, they can learn spells of various attributes without fear of being counterattacked.

And the same is true of Han Tu, which has no spiritual roots.

He placed the severed arm of the long-armed demon ape in front of him, then recited a few mantras, and brought the middle and index fingers of his right hand together, pointing to the location of the severed arm.

"Open!"

With Han Tu shouting, a hole was opened in the arm by the remaining blood. Immediately after, the blood poured out of the wound at a speed visible to the naked eye, gradually converging on his fingertips.

Amazingly, so much time had passed, but the severed arm showed no signs of drying up, and even the blood remained the same as before. This is a magical decision.

The exercises are divided into three levels: upper, middle and lower-grade, and the water control decision that Han Tu learned is just a low-grade and high-level spell, but despite this, it also used his contribution points for half a year.

This is an advanced version of the water repellent solution, which can only drive the existing water source. However, the water control decision can directly extract a part of the water attribute from the aura stored in the space and condense it into water droplets. It can also control most of the things that are presented as liquids, such as blood or tears.

Naturally, the exercises of the demon race cannot be regulated by the level of the human race, but Han Tu estimated that this arm change duel should be comparable to the middle grade of the human race as a spell, right?

The blood thickened on Han Tu's fingers, and soon formed a fist-sized, elastic sphere. Even if some children would use it as a kicker, it wouldn't be surprising at all.

It is worth noting that it is the first time that Han Tu has seen the blood of a demonic beast. Therefore, it is impossible to judge through past experience whether all the blood of the Demon Beast is like this, or only the blood suspected of containing the Demon Core will behave like this.

Han Tu took out a porcelain vase, intending to include blood cells in it. I thought it would take a lot of effort, but in fact, the moment the blood cell touched the mouth of the bottle, it had already turned into a pool of liquid and slid in.

If it comes, it saves a lot of time.

Now, it's time to begin to put the dying-out severed arm into the space created by the Arm Swap.

The first and most important point is to drip your own blood into the severed arm. The previous broken arm was originally his own, but when he got to this point, he skipped it directly.

Han Tu took a deep breath and exhaled the turbid qi in his heart.

In the same position, the middle finger and index finger of the right hand are together, and the other three fingers are in the palm of the hand. As he shook slightly, the aura swirling around his fingers left small wounds on his fingertips.

Blood gushed out along with the aura, and gradually poured into the severed arm. Before Han Tu could think about it, this broken arm had already changed.

After losing blood, the arm, which had gradually dried up, became rosy again, as if it had just been broken. When practicing with the broken arm for the first time, you don't need to directly connect the broken arm to yourself, but put it into the space of the arm exchange, and it is considered a success.

If you're worried about whether you can match or call it out, you don't have to. The space of income exchange is itself a process of testing, that is, as long as it can be earned, it will definitely be called. At least, that's what is described in the text of the Arm Swap Decision.

The severed arm gradually grew smaller and turned into countless points of light. The arm, which was originally presented as an entity, had turned into a little aura and drilled into Han Tu's broken arm.

So far, this time, the income about the broken arm can be regarded as a success.

At that time, he only had seven or eight hundred spirit stones in his hands, but he used a full six hundred spirit stones to buy this thing that had no effect on him at that time. Now, it's finally been put to good use.

Han Tu snorted coldly, and then urged to change arms. Unlike before, when he only had a single target, now he can clearly feel that there are indeed two arms in his broken arm space.

After selecting the arm of the gibbon ape, he began to activate the aura. In less than a happy time, the arm appeared as scheduled and was attached to Han Tu's broken arm.

As of this time, his arm change duel has also officially advanced to the second layer.
