Realizing the special role of the skull cup, Yu Lie immediately calmed down and conducted a more detailed study of this object.

Soon, he determined that this cup, which was made from the skull of the undead, really had a not weak soul-binding effect.

In addition to the soul, spiritual things such as yin, poison, and aura can be contained in it, and the skull can gather them without revealing a single thing.

This made Yu Lie surprised:

"It's no wonder that even a weak immortal has a huge amount of soul power stored in his body. I thought it was because the dragon flame in their eyes, or their own souls, had a strange effect. Now it seems that the skulls of these immortals themselves are also a treasure. ”

Thinking about it, Yu Lie immediately realized that this immortal skull was an excellent medicine bottle and pill bottle, which was quite suitable for holding medicine!

But the next moment, he overturned that idea again.

Such a thing with a good spirit effect is too wasteful to be used only as an elixir bottle. At least for him as a mere eight-rank Taoist disciple, it was too wasteful.

Moreover, in the process of pondering this skull, Yu Lie also tried to use the skulls of undead beings such as demon dogs to refine them, in an attempt to refine a similar skull.

But the results were not ideal.

He had to use the bronze wine cup and soak it many times before he condensed a bone stubble, which faintly had a soul effect.

However, this stubble was very different from the ready-made skull cup in his hand, and it was extremely difficult to recognize that the two were the same thing unless he deliberately perceived it.

All this made Yu Lie realize that the reason why the skull cup in his hand could be formed was not only because it had been repeatedly soaked and purified by the bronze wine glass, but also because it was also related to the raw materials that condensed it.

Whether it was the eldest daughter of the high priest who was killed by Yu Lie, or the giant head, the origin of these two in the world of the Hideous Dragon Court was not simple, and they were not ordinary undead beings.

With these two foundations, the skull cup in Yu Lie's hand was formed.

In the Dan room, Yu Liemo rubbed the skull cup in his hand, and the more he looked at it, the more thoughts he had in his heart.

Finally, he glanced at the damaged Bapindan furnace beside him, and a thought gradually became clear:

"This skull cup may be small, but it can increase its size and mass by condensing the skulls of other undead beings. It also has such a powerful restraining effect, even the soul can be restrained, and the mad dragon flame cannot be destroyed, and it is faintly still burning the cup and refining its texture...... Wouldn't it be more suitable for such materials to be used to refine the Dan Furnace? ”

The thought made Yu Lie's eyes jump.

It is said that for the people in the Dan Dao, each of the three treasures of alchemy is very important, but the fire is rare and the altar is complicated, only the Dan furnace is the most close to the people, and the effect is immediate, everyone has it, and everyone can find it.

Among them, the people in the Dan Dao who are skilled in craftsmanship often use the Dan furnace that they themselves refine, even if they are fake to others, they will only let others help refine the rough embryo, and the rest must rely on their own warmth.

In this way, the Dan furnace is the most in line with the Taoist's wishes, easy to use, and can follow the Taoist to practice for thousands of years.

It's just that Yu Lie is still just a Taoist now, his cultivation is not very profound, and he doesn't have enough financial resources in his hands, and he is mainly involved in the flesh and blood pill method.

Because the Dan furnace is a heavy weapon that fuses medicinal properties and comes into contact with flames, flesh and blood substances are inherently not fire-resistant, so they are quite restrained. Therefore, if you want to use the flesh and blood pill method to refine a side Dan furnace, the requirements for the quality and craftsmanship of flesh and blood are far higher than the use of copper, iron, metal and other things.

Therefore, until now, the Dan furnaces used by Yu Lie have been purchased from shops, and they have not tried to refine their own Dan furnaces.

Now that such a skull cup had fallen in front of him, it immediately made his mind flood with the thought of refining the Dan Furnace.

Yu Lie thought in his heart:

"Refining the Dan Furnace with this material is far more suitable for me than gold and iron. For it was conceived from the skulls of the undead. The bone is not gold and iron, not grass and trees, and it is closer to flesh and blood......"

Combing, one after another thoughts of refining the Dan Furnace appeared in his mind, and for a while he left all the things in that square door behind, and wanted to start refining the Dan Furnace immediately.

However, after immersing himself in the idea of the Dan Furnace for a while, Yu Lie still pressed his mind and broke away from it.

The additional action he made was simply to throw all the undead materials in his hand into the skull cup, use the earth fire to smelt them together, and then use the bronze wine cup to purify this strange material.

After concocting this, the skull cup fell into his hand and shrunk again, returning to the size of a baby's fist at the beginning, and could easily be tucked away in his sleeve.

The soul-holding effect of the cup is also even richer.

The wisp of mad dragon flame that had been refined by Yu Lie fell inside, wrapped in a skull cup, and the aura and soul power were all restrained, and there was no sign of leakage.

Yu Lie put the dragon flame and skull cup in his sleeve, and paced around the Dan room a few times, and there was nothing unusual at all.

Maybe if he meets the ghost surnamed Nadu again, the other party will not be able to see through the clues in his sleeve.

After tidying up like this, Yu Lie changed his appearance and hurriedly opened the door of the Dan room.

The next thing he had to do was to quickly solve the door, and then come back to study the strange material in his hand.

Maybe when he gets the money and food on Fang Men, Yu Lie may also harvest his own Dan furnace again in this assessment.

………………

The dark castle was dark, and Yu Lie consciously constricted his qi when he went out, avoiding acquaintances, and even the soul girl didn't notice that he was out of the customs.

He wandered around the lobby of the Dark Castle as a strange Taoist, and after a few days of waiting, he came across Fang Men again.

The other party really continued to be busy hunting.

It's just that the Taoists who are still alive now are not stupid, and every time they go out hunting together, they must sign a contract. A Taoist who refuses to sign a contract, or even show his face, will not be willing to be accompanied by anyone at all.

Therefore, although the gate did not recognize Yu Lie, if Yu Lie wanted to blend in with the other party's team and follow the other party's activities, it would be impossible.

Fortunately, there are more ways than troubles, since it is impossible to blend into the team, Yu Lie directly inquired about the general whereabouts of several people from Fangmen, and chased after him from afar as a lone wolf.

With his current cultivation and the hole cards in his hand, he only needs the Fang Men group to make a slight mistake in the hunt, and when the rest of the column pushes it again, the other party and his party may fall into a place of no return, and he doesn't even need to intercept and kill it himself.

Doing so will also allow Yu Lie to avoid many risks.

After all, the other party is also a Taoist disciple, and he is still a child of a family, and there are risks in the wilderness itself, no matter how anxious and confident Yu Lie is, he should not be in a hurry to ignore the risks.
