With a burst of confusion, the impregnable door finally opened, revealing a long, narrow passage that sloped upward.

Safe for now!

Tang Yin cautiously stepped into the door, only to find that the door that had been pushed open was unscathed and had not been damaged by his palm.

"This is too strong, isn't it?" Tang Yin said with emotion, with his current strength, even if it was a solid piece of steel, that palm just now could make a big hole.

And the stone gate in front of me left no trace at all.

Tang Yin concluded that either the stone itself is special, or it has undergone special treatment, and its strength far exceeds that of ordinary steel.

Not wanting to waste time, Tang Yin did not study it carefully.

Slowly walking up the inclined upward passage, digging such a passage deep underground, is a difficult project for ordinary people, but it is not difficult for the strong with strong overload power!

When he went all the way up, he didn't encounter any obstacles, and he didn't encounter any traps, which surprised Tang Yin.

I thought that I would go through some thrilling and even fatal crises, but I didn't expect that after opening the gate, the next road would be safe, and I would be worried in vain along the way.

Crash!

Walking and walking, Tang Yin actually walked out of the water.

The lower half of the passage is underwater, and the upper half is above the water, but Tang Yin concluded that it is still underwater.

He felt that the absence of water here was the effect of the formation.

There are some formations that can create a space without water in the water, even at the bottom of the sea, which is not a difficult task.

The difficulty is the problem of energy supply, the operation of the formation needs energy support, and the vast majority of formations will not produce energy on their own, but need external energy supply.

"Dry, constant temperature!" As he continued upward, Tang Yin found that this place did not look like a dark and damp underground at all.

It's not damp at all, it's really dark, there is almost no light at all, but for a super strong person like Tang Yin, as long as it's not absolutely dark, it's no problem.

Got it!

Then came to an underground space, about the size of a football field, with caves dug into the surrounding stone walls.

Some caves have something, while others are empty.

"There are traces of items that were once stored, but now they are gone, if they were not taken by the owner of the treasure, or they were stolen later!" Tang Yin carefully examined.

The empty caves were found, with obvious traces of what had once been stored, but now they were empty.

On the surrounding stone walls, there were a total of nine caves, seven of which were empty, which made Tang Yin feel a little disappointed.

It was originally a small-scale treasure, and it could even be called a miniature one, and now it has been taken away by someone How could he be happy?

"It's not bad!" Tang Yin went to one of the two caves that were not empty, checking the items stored in it.

There are some high-quality jade, each of which is of exceptional value.

There are also some precious materials, and there is no shortage of high-quality metal materials, such as the 10,000-year-old black iron in it.

"The consumables for the next stage of the Pixiu Immortal Body are guaranteed!" Seeing these materials, Tang Yin smiled.

The Pixiu Immortal Body he cultivated, either relying on the accumulation of little by little progress, or devouring the genius earth treasure to progress.

Accumulating bit by bit is a normal path of progress, and it is also the path taken by the vast majority of supernatural powerhouses, but this path is too slow.

After tasting the taste of devouring the genius earth treasure and ascending to the sky in one step, and then let Tang Yin come step by step, he felt like a year.

Now these materials are enough for him to go further.

Subsequently, he also discovered some precious antiques and medicinal herbs.

Medicinal herbs he can understand, Bi

In fact, when supernatural cultivators cultivate, they need medicinal materials to assist in cultivation, and they also need medicinal materials to heal their injuries.

But what are you doing with so many antiques?

Hey?

Suddenly, Tang Yin was shocked, he made an unexpected discovery.

The antiques stored here, a few of them have no treasures on them, is it a high-quality antique?

Tang Yin immediately took one of them, it was a jade pendant, and he was almost certain that it was Zigang jade.

However, there is not the slightest treasure on the jade pendant, the problem is that through the antique appraisal method, it is determined that this is serious.

He concluded that there would be no error in judgment and that it was a genuine antique.

"Could it be that there is anyone else other than me who can absorb and use the treasure qi?" Then Tang Qi thought of a possibility.

He was able to absorb the treasure qi with the help of the Lotus Cup.

How do other people absorb the treasure?

After they absorbed the treasure qi, how did they use it?

Tang Yin was seriously suspicious, and at the same time, he became more and more curious about the owner of the treasure, eager to know who the owner of the treasure was?

However, he checked all the way, and none of the items in the treasure could involve the identity of the treasure's owner.

When Tang Yin checked the treasure, a small boat floated on the river, and it came to the yacht of Taishan and others.

"You're Tarzan?" jumped on the yacht in the middle of the boat.

"Who are you?"

"Call the cycads and you'll know who I am!"

Taishan didn't dare to slack off, and immediately called, and soon confirmed that the man who jumped on the yacht was called Zhang Dongmu, Cycad and Taishan, and they cooperated with Zhang Dongmu unconditionally.

"Did you find anything unusual?" asked Zhang Dongmu.

"Nothing out of the ordinary!"

"Are you sure there aren't any anomalies?"

"Well, if I had to say yes, it would have been about a few hours ago, when four yachts crashed and crashed, caused by an underwater undercurrent!" Tarzan said.

"How can you be sure it's an underwater undercurrent?"

"Because I can't find any traces of anyone making trouble, and after my people go into the water, they do feel an undercurrent in the water!"

"Waste, you guys are wrong!" Zhang Dongmu scolded coldly, with an undisguised look of disgust in his eyes.

Then he jumped into the water as soon as he jumped into the water.

"Brother Taishan, this guy is too blind, right?"

"Shut up, do what you have to do honestly, and be careful that trouble comes out of your mouth!" Tarzan immediately scolded his men, and although he was not satisfied, he could only endure it.

When Zhang Dongmu went into the water, Tang Yin had already sorted out the things in the first cave, and he was still quite satisfied.

After all, looking for treasures, there are not many twists and turns, and after the inventory, Tang Yin came to the second cave with items.

In this cave, there is only one and only one item.

A chest, a square box with a side of a foot, with a smooth surface without gaps, looked like a solid block of metal.

When he first discovered it, Tang Yin thought it was a special metal material, and it was indeed a relatively precious metal material.

However, upon examination, it was found to be a box.

There are no gaps, because the level of craftsmanship is too high.

Even with modern technology, to achieve this point where the gaps are invisible to the naked eye, high-precision digital machine tools are needed.

"There is only this one box in the entire cave, and it uses the composite formation as the lock, plus the entire metal material as the box, the contents inside must be not ordinary!" Tang Yin speculated.

Of course, this is just his speculation, maybe it is empty, and he can't be sure at all now.

The formation arranged on the box is a composite formation of a variety of formations, which not only has the ability to shield various explorations,

It also has the ability to fight against brute force.

If someone cuts it violently, the box will explode like a bomb, not only killing and injuring people from the outside world, but also destroying the contents of the box.

Therefore, after Tang Yin studied it, he decisively gave up the method of brute force cracking, and could only crack the formation little by little.

The problem is that the difficulty of the composite formation is very high, and although Tang Yin is confident to crack it, it cannot be completed in a moment and a half.

"It seems that I can only bring it back!" Tang Yin picked up the box.

Surprisingly light!

It's made of metal, but when you hold it, it's like a piece of wood, and you can't feel the weight when it's fluttering.

Hey?

Tang Yin picked up the box and found that there was a mask under the box, and his appearance was actually the image of Satan in the West.

"Could it be that the owner of the treasure is a foreigner?" Tang Yin looked at the mask lying under the box, feeling a question mark in his heart.

The image of Satan, which appears in Western mythology.

In the mythology of the Chinese system, there is no Satan at all.

Tang Yin carefully checked and made sure that there were no traps on the mask before carefully picking up the mask.

It is a very light metal mask, which is cool in the hand, like holding a piece of wood.

"Come on, come on, put me on, I will give you great power......" While picking up the mask, Tang Yin suddenly felt a mental trance.

In a trance, a seductive voice told him to put on a mask, and as long as he put on a mask, he could gain great power.

Airplanes!

The cup that Tang Yin had been carrying with him suddenly vibrate, causing Tang Yin to wake up instantly, and he threw away the mask with a shake of his hand.

It's dangerous!

Tang Yin was immediately sure that the voice that bewitched him just now was clearly coming from Satan's mask.

"Evil Weapon!"

Evil weapons are also a large category, generally referring to those made by evil means, or those with evil uses.

For example, Satan's mask has the power to deceive people's hearts, and this alone can turn into an evil weapon.

"Could it be the back hand left by the treasure's owner?"

Tang Yin approached the mask with palpitations, and after calming his mind, he picked up the satanic mask again.

The bewitching voice sounded again, but Tang Yin was already prepared in his heart, only a little dizzy.

Click!

Tang Yin pinched hard, intending to destroy this harmful evil weapon, and the satanic mask was immediately pinched and distorted.

After crumpling into a ball of rotten iron, Tang Yin casually discarded it.

Hey?

Then he was shocked again, because the satanic mask that had been thrown on the ground, like a piece of elastic rubber, quickly returned to its original shape, and it was not bad in the slightest.

Tang Yin picked it up again and crumpled it fiercely.

The result is still restored, and it is still the same as before.

"Tear it up for me!" Tang Yin simply put the box down and pulled the satanic mask with both hands, trying to tear him apart.

However, it stretched out, and as soon as he let go, he returned to his original state again.

After trying many methods, Tang Yin finally became discouraged that conventional violent means could not destroy the satanic mask.

Although Tang Yin was a little discouraged by this, he didn't feel too strange, making an evil weapon can be said to be a waste of money, and if the evil weapon made can be easily destroyed, it is really a strange thing!

"When I find a way, I'll destroy you!"

Tang Yin reluctantly put the satanic mask on the metal box, picked it up and walked out, wanting to take the metal box out.

"Who is it?" Tang Yin followed the passage back to the passage below the water, and was about to step out of the gate of the treasure when a strong sense of crisis suddenly hit, making him retract his steps for the first time, and retreat all the way until he thought it was a relatively safe place.
