"Well, my solution is good, hahahaha!" Beiming laughed proudly in Du Wenxing's heart.

In the black tentacles, the trap bird is still struggling.

You can see that the surface of the tentacles that have melted into a single piece can be seen, and from time to time sharp bumps burst out.

But the body of the North Underworld is indeed strange.

No matter how hard the claws and beak of the trap bird triumph, they can't puncture it!

A minute and a half later, the North Styx retracted all its tentacles.

Bang dang!

The trap bird, which had lost its support, slammed heavily on the ground and remained motionless.

The hedron that provided energy in its body had been drained by the Northern Stygian and had lost its power, and the bird was nothing more than a dead thing.

Du Wenxing cautiously poked his paw in again, pressed it on the ground, and pressed it again, but there was no movement.

Now I can rest assured.

He kicked on his hind legs and jumped in.

"Rest assured, without hedron energy to power it, this bird is just a delicate sculpture. Beiming said.

Walking to the trap bird, Du Wenxing looked up and down, left and right, as if he had found something, his claws pressed on the belly of the trap bird, and a small square popped out, rolling out a gray fluttering stone.

Du Wenxing picked up the stone, this is the spare?

Bei Ming Dao: "This thing is also called a spirit stone, I told you before, a spirit stone is essentially an ore, but it can only be produced when the spiritual energy is abundant." ”

"In other words, quack, there is no such thing now?" Du Wenxing asked.

"Definitely not, after so many years of lack of spiritual energy, the spiritual stone veins in the ancient period have long been degraded into ordinary stones under the influence of the rules of the world, unless it is some spiritual stones preserved in the cave, because of the isolation of the cave to the rules of the world, there should still be some spiritual energy preserved in it. "The North Underworld Returns.

Dangdangdang –

Du Wenxing was a little disappointed, stretched out his claws and knocked on the body of the bird, making a crisp roar.

The tough texture fed back from it made Du Wenxing very curious about the material of this object.

"What is this bird made of?"

"What you've seen is the kind of metal that is fused in the black sand as the main material, and then mixed with some auxiliary materials, which is both strong and flexible. ”

Is the fire yuan copper gold......

"Is this metal precious, and what are its properties?" Du Wenxing asked again.

"Huoyuan copper gold is a composite metal, and its main material is fire copper. The advantage of fire copper is that it is extremely fire-resistant, but the body material is extremely soft, which can be said to be not suitable for refining anything, and it does not have the effect of copper essence to communicate spiritual power, so it was once regarded as a waste-like thing. ”

"Later, I don't know which genius senior monk actually found several special metal materials that can be compatible with fire copper, and fused them to smelt at a high temperature above Danhuo to form a special material such as Huoyuan copper and gold. ”

"This Huoyuan copper gold has the length of fire copper without shortcomings, taking into account fire resistance and strength, so it has become a very suitable special material for refining Danding. Of course, it can also be used to refine mechanism golems. It's a durable material, and you can see that the puppets on the outside are rotten, but the bird is still intact."

After hearing this, Du Wenxing reached out and touched the bird's feathers, and pressed his paws down violently.

A small handprint was pressed out with great force.

But after Du Wenxing took his hand away for about five breaths, the part of the metal feather that he pressed down was already quickly restored to its original state.

Great stuff!

Du Wenxing immediately put this trap bird into the space ring.

Then he carefully looked at the surrounding environment of the main hall.

Around the main hall are rows of metal shelves, most of which have decayed and collapsed, except for a shelf in front of the east wall that is still intact, on which are placed containers of various materials.

"This should be an alchemy room, you look at the traces of the three depressions in the center of the main hall, there should have been a Danding originally placed, I don't know who moved it, the Danding is likely to be made of Huoyuan copper and gold. ”

"Then these porcelain bottles should contain pills?"

Ignoring the collapsed garbage, Du Wenxing walked to the intact shelf and watched carefully.

The metal shelf was also made of ordinary materials, and was able to be preserved because of the runes carved on it, which slowed down its decay.

There are still grooves in the rune array on the surface of the metal frame, which are inlaid with spirit stones, most of which have been dimmed, and only one or two are still exuding a trace of spiritual energy.

If you don't come, I'm afraid it won't be long before this talisman becomes invalid.

Without the protection of the rune array, this metal frame may only last for another hundred years or so!

However, to be treated so specially, it seems that the elixir on this metal shelf should be relatively valuable.

"Hurry up, open it and see, there's anything I need!" Beiming said excitedly.

I picked up a porcelain vase, uncorked it with anticipation, and poured it twice.

Nothing!

How can it be!

Du Wenxing and Beiming exclaimed at the same time.

Then he opened a jade box, which was still empty.

No, it can't be considered empty, there are still some residues left in it.

These pills are all corrupted, but ...... Isn't there a formation to protect it?

Du Wenxing staggered up and down, speeding up his view.

Beiming also reached out tentacles to help.

Jade bottles, stone bottles, jade boxes, wooden boxes...... All sorts of containers were opened, and the results were the same.

Or see the wind and melt, or touch it and scatter, occasionally there is a box that is well preserved, take it out and take a look, the pill inside is also black like a pill of mud, all the medicinal spiritual power has long been dissipated, only these dregs remain.

"Made, there must be something wrong with the formation, resulting in only protecting this metal shelf, but the more important pill is corrupted!" Du Wenxing guessed.

"This guy refining the formation is really damned!" Bei Ming scolded unwillingly.

As Du Wenxing and Bei Ming moved around, the result was no different, except for a large number of black mud pills on the ground, there was nothing else.

"I'm!"

Beiming finally couldn't bear it anymore, retracted his tentacles angrily, and gave up in despair to stop rummaging.

However, Du Wenxing persevered and continued to check one by one.

Until there was still a jade box in the far corner of the metal shelf, Du Wenxing was also depressed, not thinking that there could be any well-preserved elixir in the last jade box, but he still opened it by inertia.

A fragrance suddenly filled the entire hall.

"Huh?"

Bei Ming suddenly came to his senses, and suddenly probed his tentacles into the jade box, and a black pill was sucked out by it.

"It smells so good!"

This was Du Wenxing's first impression.

"It's ugly!"

This is Du Wenxing's second impression.

"What is this—" Du Wenxing began.

But before he could finish asking, he saw Bei Ming angrily throw this black pill out.

The black pill hit the wall and bounced back, rolling to Du Wenxing's feet again.

Du Wenxing was suffocated with a "don't".
