The "Minister Niu" of the Logistics Department has a very domineering name: Niu Choxiong.

Slay all the heroes in the world.

It's just that compared to this domineering name, as the chief butler of the logistics department of the entire Qianlong Yuan, he manages hundreds of people up and down on a daily basis, such as eating and drinking, logistics support and coordination, etc., but he is extremely careful and cautious.

So when Niu Shuxiong crossed a few streets and walked back to the vicinity of the large martial arts arena, his pace suddenly slowed down: "Huh, no......

When the four of them arrived twenty minutes ago, he had taken a look around his surroundings - at that time, the entire row of about a hundred stables around the arena was tightly closed.

At this moment, Niu Chuxiong saw that at least six or seven percent of the stable doors were open.

"What's going on?" he glared over the empty stables, and when he looked at them, he didn't find anything else inside.

"Boss Yan will be fine, right?" Niu Chuxiong couldn't help muttering to himself, walked through the front door and looked at the tall warehouse at the end of the martial arts arena, and his heart quickly sank slightly: "No......"

The two iron-clad wooden doors that had been completely opened when the three of them walked out were tightly closed at the moment.

And with Niu Chuxiong's understanding of Yan Siguang, once the chief scientist studied the formation, he couldn't care about anything happening around him, let alone completely close the door for no reason.

He took a breath gently, and the inner breath of the "Hidden Dragon Heart Sutra" quietly operated in the meridians, and he also took out a small turquoise and crushed it at his fingertips: "Hurry!"

The pale cyan light lit up with the dance of several sword fingers, instantly enveloping his entire body.

"Too clear"!

In addition to martial arts, Niu Chuxiong also practiced Dao Gong for a period of time. This "Tai Qing Xuan" does not have any offensive or defensive capabilities, but it can make him as light as a swallow in a short period of time, and with the middle-grade martial artist Nei Xi and the secret mind and body method of the Hidden Dragon Yuan, as long as the reaction is fast enough, he may even have a chance to escape in front of the grandmaster.

"Don't be fine, don't do anything...... Boss!" Niu Chuxiong habitually muttered softly in his mouth, while deliberately slowing down his pace and walking lightly towards the two doors of the warehouse.

With a distance of more than 100 meters, it took the slightly cautious logistics minister half a minute to walk to the door, and then carefully leaned on the crack in the door and looked inside.

It's a pity that all kinds of construction techniques in this underground city are extremely exquisite, although it is an ordinary wooden door without a formation, I don't know how long ago the craftsmen built it perfectly. With the eyes of the ox, he still can't see any of them through the "gaps" of a few microns.

"Boss Yan, are you in there?"

He lowered his voice and asked softly, and after waiting for a few seconds, he didn't get any response—of course, but this doesn't mean anything, with Yan Siguang's black fat habits, don't say the name softly when he is fascinated by the study of the formation, even if he takes a string of 10,000 firecrackers and lights them in his ear, he will not have any dodge reaction.

Niu Qixiong hesitated for a few more seconds before he really pressed his heart on both sides of the iron wooden door with both hands and pushed it away violently!

Then, a subconscious "!" sounded from his mouth.

Behind the gate, not only did Yan Siguang, who was originally squatting on the ground and posing with various instruments to study the formation, no trace of him, but even the hundreds of wooden frames, densely packed armor, weapons, and saddles that were originally neatly arranged disappeared.

The whole storeroom has become a huge empty room.

He and Zheng Changlin and Ji Daoyan have only been away for less than five minutes, what happened just now?

More importantly, what about Yan Siguang!??

Where did the "most precious brain" of this Qianlong Yuan go?

Niu Chuxiong's whole heart kept sinking, and he walked around in a panic in the spacious warehouse that was almost no smaller than the martial arts arena outside, and naturally he didn't find anything. The whole warehouse is as clean as if it has been cleaned inch by inch by a high-power vacuum cleaner, not only all the shelves and equipment have disappeared, but even every blue brick on the floor is as clean as new, not at all like an ancient building that has existed for hundreds of years.

"No, you can't mess around...... Don't panic!Yes, stable!" After a minute or so he finally forced himself to calm down, and soon there was a sound of the gates outside, and the stables were open to sixty or seventy percent, and he soon went out to the nearest stable.

The stables are connected in rows, separated by logs twenty or thirty centimeters thick, and the gate of the martial arts arena is an iron fence that can be opened outward.

Like the other buildings in the city, the fence gate is made of cast pig iron, which is highly susceptible to rust, but it has not corroded over the centuries and remains in excellent condition.

The stable is also one of the six or seventy percent, and the cast-iron fence door opens from the inside out, and even the latch is exposed and not retracted. The inside of the stables is the same as the storehouse at the moment, although it is in the open air, it is still spotless and extremely clean.

Three meters long and wide, there is a fodder trough and drinking trough at the front, and a rudimentary formation and a half-man-high hole are carved on the wall behind it, which is supposed to be a passage for cleaning excrement.

The air is fresh and there is no horse excrement left on the ground.

Of course, this is not surprising, and no matter what smell may have wafted from this place before, it is unlikely that there will be any traces of it after hundreds of years.

The question is, what opened the cast-iron railing door that was still closed?

Or rather...... Something is coming out?

Niu Shuxiong closed his eyes slightly, calmed down and thought for a moment without any clue, so he could only endure his anxiety and continue to inspect the stables that had been opened or were still closed.

Didn't find it.

Didn't find it.

Didn't find it.

After a few empty stables in a row, Niu Chuxiong, who felt more and more anxious in his heart, suddenly took shape, and his eyes finally lit up with a look of surprise.

"It's ......"

——In the stable in front of me, where the gate was closed, there was a small bulge like a grave bag in the middle of the simple formation of the wall behind it and the half-human-high hole.

……

……

Although the actual combat power is not as good as Win Xingtian, the head-to-head duel is likely to be pressed and beaten by the former with an absolute advantage, just like the previous Wudao Grandmaster "Zhu Huang", but the "Yin and Yang Snake" is indeed an excellent candidate for digging tunnels.

Ying Xingtian had to sit cross-legged after bombarding more than 20 punches in a row, using the silver array plate and Nanhong agate to recover, but Xiao Yang continued to drill in the hole like a pile for more than a minute before he twisted his huge body and withdrew.

The half-meter hole, which was originally only one meter seven or eight deep, now looks like a real "tunnel" in the black hole. Yu Zhenzhen turned on the light probe and went in to take a look, and when she came out, she showed a shocked face: "It's almost five or six meters deep!"

"It's really much better than me. Ying Xingtian smiled and stood up and put the array back into his arms, and the aura on his body recovered after this period of time and returned to its peak state: "If there is really a key to breaking the labyrinth formation inside, you and your family Xiaoyang should be counted as the first work." ”

He was in a good mood, and he also wanted to follow Ji Yiming's example to pat the head of the Gu snake, but the latter turned around unhappily and hid the huge head in his body.

Ying Xingtian laughed dryly, but he didn't force it anymore.

Xiao Yangpan began to rest beside Ji Yiming, and replaced with Ying Xingtian, who had returned to his peak state, to continue to reclaim the tunnel. This top leader of Qianlong Yuan, who usually has a cold temperament and an incomparable handsome appearance, can only drill into the half-meter-diameter tunnel in an extremely ugly posture at this moment, and awkwardly bombards the inner walls of granite and basalt.

This time he was less efficient and took longer than before.

In the booming explosion, there were many fewer stones thrown from the hole than when Xiao Yang came into the field. The seven members of the Ruins Exploration Department next to him looked embarrassed, and after waiting for less than twenty seconds, they could only turn their heads when they saw Ying Xingtian crawling backwards from the entrance of the cave, covered in dirty lime...... Pretend not to see.

The ugliness of the direct leader is not something that anyone dares to look at with their eyes open.

"It's a meter five deeper, and now it's almost eight meters. Win Xingtian shook the lime on his body, and took out the array disk again to restore the internal breath of "Xingtian Decision": "At this speed, the entire tunnel can be opened in about one or two hours." ”

Ji Yiming also sat cross-legged beside him, holding the array disk in his hand and secretly running the inner breath of the "Taiyi Longevity Formula". He took a little longer to breathe than the latter, and although all the internal breath had been exhausted before, he had almost recovered three or four out of ten at this time—and then he consciously pressed one hand on the body of Gu Snake Xiao Yang, injecting the few internal breaths into his body with all his strength.

Gu Snake's usual cultivation relied on devouring other Gu Poison Insects, and during this period of time, he was always digesting the powerful power contained in the flesh and blood of the original Ancestor Gu's body, but there was no shortage of food. And the array disk developed by Yan Siguang is obviously useless against snakes.

Fortunately, the Yellow Emperor's method of passing on the heart of the Yellow Emperor "Taiyi Longevity Formula" practiced by Ji Yiming is obviously much more effective than the ordinary array plate for the "Yin and Yang Polar Snake", and in just a short period of time, the aura on Xiao Yang's body quickly climbed, and soon recovered to a level close to the heyday.

"Go ahead. Ji Yiming patted its tail, but Xiao Yang first raised his head and glanced at Ying Xingtian, who was still weak, next to him, and then twisted his huge body and went directly into the tunnel.

The latter smiled dumbly, shook his head and turned to Ji Yiming: "You and it do complement each other perfectly, obviously it is just a martial artist's low-grade breath, but it can instantly restore a top grandmaster, the Yellow Emperor's heart method, it is really magical." ”

As the two spoke, there was a dull explosion like an explosion in the tunnel, crackling with countless rubble sloping out of the hole.

Everyone was thrilled when they heard this, not only Li Xiang and the other seven members of the Ruins Exploration Department, but even Yu Zhenzhen was beautiful, and Lian Shan looked at Ji Yiming with an envious expression: "With such a Gu thing by your side, except for meeting Boss Win, you can go almost anywhere in the world." ”

The latter opened his eyes from his cross-legged pranayama state and looked at her, smiling weakly.

It is continuously consumed, and after recovering some internal breath, it is all transmitted to Xiaoyang. This kind of cyclical wear and tear even made him feel like he had run out of oil.
