Chen Xiaoyun said, her eyes stepped forward, and she almost looked at the sharp stone.

"When you brought down Shinya Kishimoto's body, did you clean up the blood stains on it?" Liu Wuxin asked after sitting down in Ruonan's co-pilot position.

"Bloodstains?" After Chen Xiaoyun glanced back at her strangely, she immediately had an epiphany: "There is no blood left on it at all!" ”

"Then there are only two possible scenarios, either someone has come to clean it up, or this thing itself will absorb blood!" However, Chen Xiaoyun immediately asked herself again, "It's so remote here, if there is nothing special, no one will come at all, so I personally prefer that it will absorb blood!" ”

So Chen Xiaoyun let go of the mecha that wrapped her hands, revealing a pair of snow-white jade hands, and was about to cut blood for testing.

"Xiao Yun wait...... Gongsun Yun blocked behind him, seeing Xiao Yun's suspicious eyes, Gongsun Yun continued, "Use mine!" ”

Liu Wuxin looked at Gongsun Yun, who took pity on the fragrance and cherished the jade, smiled appreciatively, and then stretched out his hand to pull Chen Xiaoyun and make way for this good man who took the initiative to donate blood.

The two girls looked at each other and smiled, watching Gongsun Yun show one finger, and then watching the golden light on his other hand flash, like a scalpel cut a cut on the finger, bright red blood instantly oozed from the broken skin, and was carefully dripped by Gongsun Yun on the black stone tip.

The second girl watched as a drop of blood dripped on it, and then looked closely, but saw that the blood was immediately absorbed by the dark stone, and in the blink of an eye, there was no trace of blood on it.

The three of them glanced at each other, and when they saw that it was not what Xiaoyun expected, they couldn't help but be surprised.

"And then?" Gongsun Yun sucked the fingertips of the wound with his mouth, "This stone does absorb blood, but what can it mean?" ”

Gongsun Yunzheng asked, but saw Chen Xiaoyun's eyes close to the stone tip and looked closely: "Senior sister, come and see, what ...... is this?" ”

Liu Wuxin listened to her words, thinking that he should have found something special, so he immediately stepped forward, and just happened to see Chen Xiaoyun gently rubbing the part above the sharp stone where Gongsun Yun was dripping blood with one hand.

I saw her fingertips scratch the surface of the sharp stone, and the seemingly dark and unusually strong surface of the stone was easily peeled off by her fingers, revealing a layer of smooth material like glass inside, but the peeling place was limited to the part where Gongsun dripped, and the rest of the stone was still extremely strong, and no matter what, it could not peel off more.

"It looks like there's something strange about the material inside, and there's something special hidden in it, but we still can't know what it looks like without removing the surface." Chen Xiaoyun frowned as she spoke.

"That can only be ......," Liu Wuxin said, looking at Gongsun Yun who was still holding his fingers with Chen Xiaoyun at the same time.

Feeling the second daughter's eager eyes, Gongsun Yun stretched out the finger that had begun to coagulate blood again rather helplessly.

As more and more blood was evenly dripped on the top of the sharp stone, after they watched Gongsun Yun's blood be absorbed by the stone again, Chen Xiaoyun tried to peel off the rest of the surface ore at the apex again, and sure enough, as long as there was a place stained by Gongsun Yun's blood, he could easily peel off the epidermis.

"Back then, Kishimoto Shinya's blood was smeared all over the sharp stone, why didn't it have this effect?" Chen Xiaoyun said strangely while carefully buttoning it.

Of course, no one could answer her question; She quickly cleared the tip of the sharp stone from a small section of the dark surface of the ore, revealing a small section of the smooth, jade-like conical tip.

Then Chen Xiaoyun observed its surface again, but the mecha still couldn't identify what this seemingly jade thing was. Then she suddenly noticed that there was a thin slit at the junction between the bottom of the cone in front of her and the rest of the lower section.

With this astonishing discovery, Chen Xiaoyun immediately turned her head to look at Gongsun Yun again.

Feeling his wife's gaze again, Gongsun Yun, who was stopping the bleeding on the side, said nervously: "Isn't it enough? ……”

Chen Xiaoyun sneered and said, "I don't want your blood, let you come and see this, senior sister, too!" Chen Xiaoyun said, pointing to the gap at the lower end of the cone.

Although the gap was extremely thin and not easy to detect with the naked eye, under Chen Xiaoyun's guidance, the two of them quickly saw the existence of that gap as well.

"It's a craft product! It can never be natural! Gongsun Yun was surprised.

Chen Xiaoyun nodded in agreement and said, "Since there is a joint gap, its function should be a mechanism knob......!" As she spoke, she gripped the tip of the jade, twisting her hand vigorously, but to her astonishment, she couldn't spin it, "Isn't it a writhing ......?" ”

As she spoke, she pulled out vigorously for a while, but there was still no movement.

Seeing his wife's deflated look, Gongsun Yun's heart moved, and he said, "Why don't you let me try?" ”

As he spoke, he stretched out his hand that was still oozing a trace of blood, held the tip of the jade, and twisted it vigorously, with the movement of his hand, there was an extremely ethereal and crisp "click" sound of the rotation of the machine shaft around him, and when he heard this sound, the blood on the three of them immediately boiled, and the excitement was overflowing.

"Why can't I turn?" Seeing that the movements of Gongsun's hands were not effortless, Chen Xiaoyun asked puzzledly.

Gongsun Yun raised his eyebrows at her, and said proudly: "If you eat my blood, it should be turned by me, this is very reasonable." ”

"Hmph, I didn't need your blood if I knew I wouldn't have to, look at you!" Chen Xiaoyun said unconvinced.

"It's useless, I think this thing can only use my blood, and it can only be turned by me!"

"Huh? And this kind of thing? Chen Xiaoyun said with a look of disbelief, and as she spoke, she was about to prick her finger to take blood, to prove that what Gongsun said was untrue.

"Don't stab, this thing is just a palm-print lock, it's not hard to understand!"

As soon as Gongsun Yun's words fell, the knob in his hand had already twisted his head, followed by the sound of the machine shaft around the entire cave, and the mountain began to vibrate frequently, causing the imperial soldiers standing guard outside to panic.

The three people in the wreck of the explorer also reacted very quickly, and when they saw that a mechanism was opened, they immediately drilled out of the wreckage of the spaceship, and while signaling the sergeants to calm down, they were fully armed and carefully guarded.

Soon the amplitude was pushed to the apex, they only heard a sudden sound of water at their feet, their hearts jumped, and immediately turned their heads to look at the waterhole on the side, but found that a big hole suddenly cracked in the center of the waterhole at their feet, and the pool water flowed into the big hole, and then the stones on the edge of the big hole collapsed and sank downward, and before anyone could react, the surrounding sound stopped abruptly, and the mountain also stopped shaking.

Everyone looked at each other, looked down at the big hole, but found that the stone that had just sunk neatly formed a staircase that extended downward, and looked down the staircase, but the bottom was not deep, and the bottom of the staircase could not be seen at a glance.

Seeing that there was a cave under this, everyone was amazed, feeling the slightest cold air transmitted from the bottom of the cave, Chen Xiaoyun shuddered, and did not dare to venture for the time being, so he threw his hand to the bottom, and immediately two small ladybug-shaped reconnaissance planes flapped their wings and flew down the stairs.

As the ladybug-shaped small reconnaissance machine continued to go deeper into the ground, a grand underground palace map was clearly displayed in front of Chen Xiaoyun; Looking at the magnificent underground palace map in front of her, Chen Xiaoyun was stunned, and faintly felt in her heart that this time it would definitely not be nothing!

Chen Xiaoyun was so excited that she immediately shared the topographical map with the rest of the people, and then she wanted to jump down the big hole and go down the stairs to find the treasure that was so tightly hidden deep underground.

"Xiaoyun wait!" Gongsun Yun stopped his beloved wife who was gearing up, looked at her impatient face, Gongsun Yun smiled, and continued, "Don't worry, you still have to pay attention to safety!" As he spoke, he glanced at the sergeants next to him.

The sergeants understood this, and immediately took out a number of half-human-high mechanical dogs from their own pockets and placed them on the ground, and then the sergeants led the dogs to the head, followed the stairs, and carefully touched them down.

Liu Wuxin, Chen Xiaoyun and Gongsun Yun, who were guarded by the army, looked forward with the spotlight on the mecha and their extraordinary eyesight when they were halfway down, and couldn't help but be shocked by the scene unfolding in front of them!

At the bottom of the stairs, it should not be said that it is a buried palace, but that it is an underground city that is deeply hidden!

There are many buildings in the city, all the buildings are neatly planned, even the height of the buildings is built according to a certain proportion, and then look at the intertwined roads, the streets have a strong atmosphere of civilization, but the black lights everywhere are blind, there is no trace of the existence of half of the human population, and it is unusually quiet everywhere, obviously this is a dead city!

"It's a lost civilization again, and I don't know how many thousands of years have been buried here? Looking at the neat architectural planning of this city, I think it must have had a very brilliant intelligent civilization at that time, but I don't know where the people here went later......? Chen Xiaoyun muttered in amazement.

"I'll take a look around the city later, and maybe I'll find some clues!" Gongsun Yun replied.

"But the scale of this city is not small, and it is quite a challenge for your treasure hunting!" While Liu Wuxin spoke, his eyes looked as far as possible.

Chen Xiaoyun and Gongsun Yun expressed their disdain to her words, with their current means, they are not afraid of how big the place is, they are afraid that there is no treasure at all; As long as there is any artifact hidden in this city, let alone the scale in front of them, even if it is several times larger, it will not escape their search!

Before they knew it, the group had come to the bottom of the stairs, the edge of the city in front of them, the dark streets in front of them, and the sergeants gathered around the three leaders, waiting for the commanders to give orders.

Gongsun Yun pushed aside the crowd and walked to the middle of the street to look into the depths of the avenue in front of him, and he was surprised to find that although the buildings on both sides were all pitch black, judging from the appearance of the buildings and the planning of the road, the city in front of him was quite similar to the architectural style of other cities in the imperial state!
