Niu Chuxiong looked at the "small grave bag" in the stable, which was less than half a meter high and covered an area of just over one meter in diameter, and did not immediately enter it to inspect it. He first continued to take out a small cyan turquoise, crushed it, and then gave himself a "too yin" order, and after the cyan light with a powerful defensive effect enveloped his body, he carefully opened the iron railing latch from the inside and slowly entered.

This tomb bag looks unremarkable, not made of bluestone slabs or bricks, but more like a small earthen bag piled up at random. But Niu Chuxiong seemed to grasp a life-saving straw, and could only hope that this strange appearance of the "grave bag" might really be related to Yan Siguang's disappearance.

He walked carefully around the tomb first, and saw it clearly from all angles, even a few small holes in the bulge, what kind of soil was used, and other details. It's a pity that even so, in the face of such a bland "clue", Niu Chuxiong still failed to find any traces related to Yan Siguang.

After hesitating for about a minute, he finally took off the backpack behind him, took out a metal rod used by Yan Siguang to set up the array, and gently poked it on the side of the grave bag near the wall of the stable.

Nothing happened.

Niu Chuxiong forcibly suppressed the disappointment in his heart, and changed his position again, this time with a little more force, and directly inserted the front end of the metal rod into the soil of the burial bag.

It is firm and hard to the touch, and although it is only dry soil that has congealed into lumps, it is not even as strong as ordinary rock. Even with his mid-grade martial artist strength, it took a little effort to insert the metal rod into it.

One inch.

Two inches.

Three inches.

As the tip of the metal rod pierced into the tomb inch by inch, Niu Shuxiong felt that the resistance from inside was getting stronger and stronger, and after about four or five inches, no matter how much he poured into the inner breath of the Hidden Dragon Heart Sutra, he could no longer penetrate even a fraction.

"What the hell is so hard?" he frowned, pulled out the metal rod and put it aside, leaned over to carefully observe the small hole that had been pierced by himself, "Huh, what is this......"

In the hole the thickness of the little thumb, it is impossible to see what is inside, but under the light, it reveals an extremely bright metallic luster. And as Niu Chop's head got closer and closer, he even felt that there was a sharp and cold aura like a divine weapon in this luster.

For example, when there was nothing unusual in the treasury of the martial arts arena, the spear triggered by Ji Daoyan's inlaid gems was even stronger, ten times more powerful...... Even a hundredfold!

But there was no danger.

Niu Chuxiong's heart settled down a little, and he took out a short-handled shovel in the shape of a sapper shovel, and shoveled it towards the small grave bag one by one. The martial arts cultivator of the realm of a middle-grade martial artist did his best, and although the soil of the tomb bag was hard and solid, he was quickly used by him to directly peel off the entire soil bag layer by layer with this "sapper shovel".

In about forty or fifty seconds, a thick layer of crushed soil had been laid on the ground. And the wisp of metallic light hidden in the middle of the small grave bag finally revealed its true face in front of Niu Chuxiong.

"It's ...... Helmet?"

Placed on the ground was a full-face helmet with a silver body and a single horn on top. The two sides extend at least to the neck, and the front mask is carved in relief with a hideous skull pattern.

The icy and sharp aura escaped from the helmet.

After the actual excavation, this breath is even stronger, and even the temperature of the surrounding air has dropped slightly.

What is this thing for?

Niu Chuxiong was a little disappointed in his heart - no matter how precious this battle armor helmet was, it was far less important to Qianlong Yuan than Yan Siguang alone.

He toyed with his helmet and set it aside to dig face down towards the grave. It's a pity that several bluestone slabs have been pred open in a row, and the bottom is only wet soft soil, and there is no other discovery.

The logistics minister of Qianlong Yuan hesitated for a moment, and could only pick up the helmet and carry it in his hand, and continued to investigate the remaining stables. As time passed, so did his worries.

What kind of danger is hidden in this extremely strange cultivator city to make a big living person like Yan Siguang and the thousands of pieces of armor, weapons, and saddles in an entire warehouse disappear silently?

The next few stables were empty, no matter whether the railing hole was open or closed, Niu Chuxiong did not make any new discoveries, but when he inadvertently played with the helmet with the cold and sharp aura in his hand, he opened the mask to find that the inside of the armor, which was made of stainless steel and barely saw any seams, was also etched with a small formation.

The only difference is that it is more elaborate and complex than the simple formations on the standard armor and weapons in the warehouse, even if Niu Shuxiong can't recognize the effect of this unfamiliar formation, he can also see that it has a more complex structure and a more powerful effect than the former.

After inspecting more than 30 stables in a row and finding nothing, just when Niu Chuxiong was anxious and planned to leave here to look for Yan Siguang's traces elsewhere, the same "grave bag" finally appeared inside the next stable.

It is slightly larger than the previous one, more than half a person tall and more than a meter wide in diameter.

"What could it be in here? Could it be that after the helmet, the cuirass would not be?"

Qianlong Yuan's logistics minister sighed a long sigh, and directly raised the sapper shovel a little listlessly, digging towards the hard soil of the "grave bag". He didn't encounter any danger for so long, even if he was used to being a little cautious, he couldn't help but relax a little, and the two Dao methods of "too yin" and "too clear" on his body made the light disappear, and he didn't spend his internal breath and turquoise in time to replenish it, so he just smashed it directly with a shovel in his hand.

"Boom!"

Just when he was unprepared, an incomparable force of shock suddenly came from the grave bag, accompanied by a deafening roar, shaking his whole person into the air and smashing his back into six or seven stable walls all the way, before he fell to the ground like a sandbag!

Before the logistics minister, who had the strength of a middle-grade martial artist, could not even react, he spat out red blood in his chest. His whole body seemed to fall apart, from his chest to the back of his lower abdomen. From head to toe, I was not shaken by the force of the earthquake, and I lay on the ground covered with rubble for I don't know how long, before I barely half got up, and looked through the broken wall six or seven degrees in front of me, looking dozens of meters away.

The location of the half-human "grave bag" was empty.

Not far away, there stood a tall and strong figure—wrapped in matte metal armor and armed with a two-meter spear, with only its entire head exposed.

A strange face as hard as a knife and an axe is revealed, and the back of his head is combed with a black bright braided braids that modern people often see in film and television works.

This is...... Qing soldiers?

……

……

Ji Yiming and Yu Zhenzhen's time calculation is slightly off.

Ying Xingtian's recovery speed became slower and slower with the passage of time, although Gu Snake Xiaoyang was able to quickly recover his strength with the help of Ji Yiming's Yellow Emperor Inheritance Method, Taiyi Longevity Formula, but the latter's own recovery speed was also due to continuous exhaustion, and he had to stop and rest for at least half an hour in the middle.

When everyone present saw his appearance, they were a little embarrassed to climb into the deeper and deeper tunnel, and with the strength of the realm of middle-class martial artists, they helped to "reclaim" some of the amount of work.

Unfortunately, the efficiency is very limited, and it can only be regarded as better than nothing.

When the pit is more than 40 meters deep, everyone has to go to the field together and continuously transport the smashed gravel in the form of an assembly line - this is fortunately because the rock here is hard, and the diameter of the pit tunnel is always maintained at a narrow width of about half a meter, otherwise just the middle column to prevent the collapse can be difficult for everyone.

I don't know how many times I took a break, Gu Snake Xiaoyang was frantically hitting the rocks with his head in the tunnel, and continued to dig deeper. Seven members of the Ruins Exploration Department, and even Yu Zhenzhen, got into the tunnel to help transport the rubble out of it. Only Ying Xingtian and Ji Yiming sat not far away, looking at the piles of rubble around them that almost filled the entire corridor, and they both felt a little tired and tired.

"It's still seven or eight meters away from where you have a sensor, did you still have a sense when you just entered?"

Although he trusted Ji Yiming's judgment very much, as he got closer and closer to his destination, Ying Xingtian couldn't help but feel a little hesitant in his heart, and looked at the rubble that kept pouring out of the entrance of the cave and asked.

Ji Yiming's recovery efficiency with the array disk was much slower than that of Ying Xingtian, and coupled with the continuous cycle during this time, his whole face had become a little pale. But when he heard the words, his expression was more certain than before: "It's getting closer and closer, and the spiritual sense is getting stronger and stronger." Although it is almost impossible for the spiritual sense to penetrate far out of the body with the current internal breath, the things behind the stone wall also make me feel more and more intense. ”

Ying Xingtian nodded reassuringly, and asked more: "What about the danger?"

The former was silent for a moment, and for the first time there was a little uncertainty in his tone: "I don't know." ”

"In the exploration of ruins, dangers are inevitable. In any case, it is better than being trapped in the corridor like now, with no hope of even getting out. Ying Xingtian glanced at the "hole" that shone with a dim light in the distance, and knew that although this thing was always within everyone's sight, but in fact, after the labyrinth formation that did not know the distortion of time and space, it was almost impossible to get out on his legs: "Wait a while, you will go in last, the Gu snake will be by your side, be careful yourself." ”

"Thank you......" Ji Yiming was silent for a while, still not understanding why this Hidden Dragon Yuan boss, known as the top martial arts master in the world by force, would be so blue-eyed to himself. But in any case, this unconditional concern still warmed his heart, but he didn't know how to express it in return.

Ying Xingtian didn't speak again, watching the people in the tunnel and the equally exhausted Gu Snake retreat, he quickly stood up and clenched his fists, and drilled into it again.

After a while, the deepest part of the tunnel, which was already more than fifty meters, remembered the rumbling sound of punches.
