The air here is already extremely thin, and if it weren't for the long aura of a martial artist, it wouldn't be able to withstand it at all.

Passing through the narrow passage, what appeared in front of Lin Chen and Zhou Jing was a huge metal building, exuding the color of black gold, and it seemed to be an invincible fortress that could not be destroyed.

The walls are inlaid with countless fist-sized hedrons, which bloom with a scorching brilliance and can be regarded as a stable source of light.

To Lin Chen's surprise, this is not the imaginary imperial mausoleum, and the overall layout is a bit like a super warehouse, covering an area of no less than fifty acres.

The entire metal building has no portals, and the walls are so smooth that there is not even the slightest slit, as if it were a fully enclosed whole.

"What the hell is going on, this is an arsenal?" Lin Chen frowned.

"Almost," Zhou Jing smiled, "About five hundred years ago, Emperor Taizu of our Great Zhou Dynasty ruled the world, but at that time, the country had not yet sat firmly, so he prepared a back road and hid one-third of the treasures of the Xiuwu Empire here." So that one day, if there is an accident, the descendants of the Zhou family can rise again with this treasure. ”

"Oh, how do you know?" Lin Chen asked.

As far as Lin Chen knew, the city where Zhou Jing was located was not large, and it was far away from the power center of the "Great Zhou Dynasty", which made it feel like a bit of exile on the border.

If it were a favored royalty, it would never be like this.

"Don't ask about this," Zhou Jing sighed, "You just need to know that my branch is the orthodoxy of the royal family, but after several internal power changes, it has been miserably squeezed out." ”

Lin Chen nodded, and didn't say anything more.

The situation she said was indeed conceivable.

It is impossible for the huge dynasty to be peaceful all the time, it is normal to experience some turmoil, Zhou Jing may be a descendant of Emperor Taizu, but after hundreds of years, he has lost power.

Does she want to use this treasure to regain control of power?

The two continued to walk forward, and a surprising scene appeared.

In the middle of the corridor, there are a lot of broken dry bones, and there are broken swords and weapons next to them, it seems that someone once broke in, but unfortunately fell here.

Among these dry bones, there are remnants of palpitating vitality fluctuations, and it is conceivable that these predecessors are powerful.

"It's all martial saints?hehe, they may have discovered this place by accident, but they can't get the treasure. Zhou Jing pointed to the wall and said, "Take a closer look there." ”

Lin Chen raised his eyes and immediately found that there were many fist marks and sword cutting marks left on the black-gold wall.

Obviously, those martial saints who broke in tried to forcibly open the storehouse, but they all failed.

Emperor Taizu of the "Great Zhou Dynasty" should have considered this kind of problem, and used extremely special materials to create such a place, no matter how strong your destructive power is, it is impossible to forcibly break in.

Otherwise, this place would have been looted long ago.

"It's kind of interesting. The corners of Lin Chen's mouth raised an arc and slowly walked forward.

He stretched out his palm and pressed it against the wall, feeling very cold and hard.

Bang! With seventy percent of his strength, Lin Chen slammed into the wall.

He was almost shattered by the force of the shock, but the wall was only left with a shallow mark.

"There's no need to try, it's useless for the ninth-order martial saint to come over, even if they can move mountains and reclaim the sea, it is impossible to break this layer of defense. Zhou Jing's face was proud, obviously he knew a lot about the treasure house.

"Then how do we get in?" Lin Chen asked curiously.

At the same time, his gaze swept over the dry bones on the ground.

I didn't find that things like space rings, logically speaking, shouldn't be like this.

To be able to cultivate to a high-level martial saint, there is absolutely no shortage of martial arts resources, and there must be a treasure that can be stored.

Then there is only one explanation, someone swept through this place, and took all the valuable things with them after they fell.

"Don't worry, come with me. Zhou Jing calmly and confidently led the way in front, "But don't get your hopes up too much." I can only open the periphery, a few small treasure houses, which should be enough for the two of us to cultivate to the fifth order martial saint or above. ”

"Hmm!" Lin Chen remained silent.

It seems that she guessed wrong, the little county lord is not so ambitious, she just came over to take some things to help her improve her strength.

However, Lin Chen didn't fully believe her words, and there seemed to be a lot of secrets in the little county lord.

After walking around the perimeter of the treasure house for about a quarter of an hour, Zhou Jing suddenly stopped.

She looked up to the left and right, and suddenly she flicked her fingers, hissed, and a wisp of finger wind flew out, hitting a hedron that radiated brilliance.

The hedron directly recessed, and then, as if something had been touched, a pale yellow crystal ball rose from the ground.

Lin Chen watched silently, only to see Zhou Jing bite his fingertips and drop a few drops of blood on the crystal ball.

Something strange happened, these few drops of blood seeped into the sphere, and the color of the crystal ball quickly turned red.

"Only the bloodline of our dynasty can open the treasure house, so outsiders don't think about it. Zhou Jing explained.

"I see. Lin Chen said.

No wonder those Martial Saints didn't gain anything, it seems that the builders of the treasure house have long thought it through.

Even if outsiders are lucky enough to find the crystal ball, they can't meet the harsh conditions, and they won't even know how to toss this thing, and it won't blow it up with one punch.

Click...... The trap activates again, retrieving the crystal ball.

Then, on their left, an entrance quietly cracked open in the previously smooth wall.

"Huh?!What a terrible chill!" Zhou Jing was also startled.

Because from the entrance, a chill that was cold to the bone marrow emanated, and the white mist inside was filled, like the source of ice and snow.

Lin Chen looked at it and found that it was a secret room that was only a few square sizes, and a thick layer of frost had condensed in the secret room.

The reason for all this is that there is a special miserable white hexahedron on the case placed in the middle of the secret room, and it is there that the terrifying chill originates.

Moreover, there seems to be something hidden in it, which is vaguely indistinguishable.

"What is this?" Lin Chen said curiously.

"Earth Mother Hanjing, Baby, Lin Chen, you've sent it!" Zhou Jing said in surprise, "I'm going to refine it, I want the storage spirit ring hidden inside." ”

Earth Mother Cold Crystal?Storage Spirit Ring?

Lin Chen was a little surprised, he was covered in green flames and flew directly into it.

"That's right, only you can refine it!" Zhou Jing said again, "This is what Emperor Taizu got by accident, refining the Earth Mother Cold Crystal, you are equivalent to three hundred years of ice system vitality, and one move can freeze the Quartet!"

"I see. Lin Chen suddenly reached out and grabbed the hexahedron in his palm.

If there was no earth fire to protect him, he would have turned into an ice sculpture directly.

It seems that although Zhou Jing is a descendant of the royal family, if he wants to obtain the treasure left by his ancestors, he still needs to go through the test.

The treasures in the entire secret room should be hidden in the storage spirit ring that Zhou Jing said.

It sounded like this kind of thing should be of a higher grade than the space wrench that Lin Chen had obtained before, and it could hold more things.

Coming into contact with the alien fire, the Earth Mother Cold Crystal quickly melted, and a terrifying chill drilled down the Lin Chen's meridians to his heart.

In just a snap of his fingers, Lin Chen's hair and eyebrows were condensed into frost, and after a while, his whole body was frozen.

However, Lin Chen did not panic, but was happy in his heart, and his mind was unprecedentedly calm.

It seemed that refining the Earth Mother Cold Crystal would take a certain amount of time, but he was not in a hurry.

"Hold on! Whether you can win the treasure or not is up to you!" Zhou Jing's face was full of anticipation, revealing a pair of cute little tiger teeth.

It was at this time.

On the other side of the road, there was a sound of footsteps, as if someone was approaching, and they did not hide their whereabouts.

"Who?!" Zhou Jing was startled and immediately turned his head to look.

"Little county lord, it's us, how can we have good things to ourselves? A sinister laugh came.

What appeared turned out to be Cheng Moyan and Ding Kunpeng, both of whom were excited, and there was a sense of pride that they had succeeded in their tricks.

"How could it be you, you dare to follow me?!" Zhou Jing's face became solemn.

"Tracking? non-existent. Cheng Moyan said with a smile, "To tell you the truth, Brother Ding and I are both first-order martial saints, but we have hidden our strength with secret techniques. I have long recognized your identity, so I have placed a wisp of divine thought on you, and our whereabouts are all in our hands. ”
