Super Skull

Finding a relatively small skull, Liu Ang injected gray energy into it, and began to run the advanced bone refining method. 【 】

After the gray-black energy was injected, the skull made a "sizzling~!" sound. After about a minute or so, the gray-black energy moved and finally began to follow the advanced bone refining method.

"Wow! It's done!" Liu Ang was overjoyed. He finally found the energy that could replace the soul fire for advanced bone refinement.

Since the last time all the soul fire was consumed for this black skeleton left hand, Liu Ang regretted it a bit. The only advantage of this black skeleton hand is that it does not need to be refined, which can save a lot of soul fire.

But it's different now, Liu Ang finally discovered that the real benefit of the black skull's left hand is that it can absorb the energy of the magic core and use it for himself.

The energy of magic cores can be used for advanced bone refinement. This unexpected discovery made Liu Ang very excited. He immediately absorbed more than ten magic cores of mad rat beasts in one go, and then transferred the energy of these more than ten magic cores into Perform advanced bone refinement.

"Zizi!" The skull began to be washed from one piece, two pieces, three pieces...

After the elementary and intermediate stages of bone refining, advanced bone refining was no longer difficult for Liu Ang, so he started to practice directly.

However, when Liu Ang successfully washed the three skulls, he had to stop because he had consumed all the more than ten magic cores.

Liu Ang secretly calculated that a total of twelve magic cores were consumed, and now three skulls have been washed, plus the one tested before, a total of four. Proportionally speaking, each skull consumes three magic cores on average, of course Some bones are larger and require more magic cores.

If the volume is not divided, if it is counted by quantity, if the 206 bones are to be completely washed, a total of 618 magic cores are needed.

Although the little witch has stayed in the Mad Rat Beast area for five days, due to the lack of magic power of the Little Witch, only more than 30 Mad Rat Beasts have been killed in the five days, and the second-level Mad Rat Beast Demon Core is also There were only more than 30 of them, half of which were used by the little witch to practice undead magic, and the remaining half were just used by Liu Ang.

Not to mention the reaction of the little witch who knew that he had used more than a dozen magic cores, if Liu Ang wanted to successfully cultivate advanced bone refining, the magic cores needed were far from enough.

"We must get more second-level mad rat beast cores!" Liu Ang thought to himself.

Due to the lack of strength of the little witch, it is still daytime. Liu Ang stood up from the ground and looked at the herd of mad rats wandering not far away. About ten meters to the left, there was a mad rat. The Rat Beast was walking alone.

"Let's just do it!" Liu Ang decided to target the Mad Rat Beast first.

After pulling out the cuttlefish sword, Liu Ang didn't hesitate anymore, and rushed directly towards the Mad Rat Beast.

The strength of the second-level mad rat beast is about the same as that of the fourth-level skeleton soldier. With Liu Ang's current strength, he is still capable of dealing with a second-level mad rat beast. In addition, Liu Ang holds a sharp cuttlefish sword in his hand and martial arts skills. The champion's swordsmanship is even easier to deal with a second-level monster with not very high intelligence.
