"However, Dao soldiers can go back, but you can't go back." Sanqian Plum Blossom said: "I found something interesting in this Wolf Crying Mountain, because I want to use the three-element force to protect the safety of the warriors, so I didn't go deep, now that you are here, I think it is necessary to go in and have a look?" ”

"Really?" An Xiaoyu glanced at the three thousand plum blossoms, she knew that the three thousand plum blossoms would definitely not speak casually, especially when it was related to the return of the four thousand soldiers. If it weren't for the fact that there might really be something good in the Wolf Cry Mountain, the three thousand plum blossoms would definitely not say such a thing.

After thinking about it, An Xiaoyu nodded and said, "Okay, but I have to send the Dao soldiers back first, the empire has had an accident recently, and I think it's time to use a large number of Dao soldiers." ”

Three thousand plum blossoms were stunned, but they didn't expect that something big had happened in the empire in the past few days, and while the two of them walked out, An Xiaoyu briefly told him about the changes in the past few days. After hearing that the submarine and the Chengyi base were all wiped out, the three thousand plum blossoms also became serious.

"I haven't done it until the alien race really has the means to counter us, I just hope that Jiudaoguan can find out something quickly, right? Otherwise, you have to use the old way. ”

"The old way?" An Xiaoyu was curious: "What old way?" ”

Sanqian Mei said: "The old method is to send a large number of cultivators out, or go to the territory of the alien race to find out the news, or create chaos, and take the opportunity to let the spies in the alien race operate to find out the news of the other party. However, this kind of action generally requires a lot of cultivators, and can only be used when there is no way out. ”

An Xiaoyu knew that the so-called old method was actually such a method, allowing a large number of cultivators to impact the stability of the alien territory, and it could indeed play such a role. But it is uncertain where the aliens are hiding that method, and which race is responsible for this information.

If you rely on such a number of people, you can know how much cultivation resources will be consumed if you think about it, even if the great cause of the imperial country is great and the number of cultivators is innumerable, it will not be able to withstand such consumption. And even if the corresponding news is obtained, with the turmoil, a large number of spies who have been lurking in the alien territory for many years will be exposed.

It may even reveal the identity of the black pupil......

After all, if you can counter the methods of human detection, I am afraid that the alien race will arrange complete preparations to prevent human detection. Even if it is a human spy who goes deeper, it is impossible to go to that level, and he can only selectively sacrifice a large number of people to achieve his goal.

"Let's see how the investigation over there in the Nine Dao Pass goes!" An Xiaoyu sighed and said: "If the Nine Daoguan can't be investigated, it's a big deal that I will stay here in the west for a while, and I can always meet them before I do it, and then I won't believe it and I won't be able to see what means they used." ”

"You don't want to go online, we still have to do something about the origin and the end, what's the matter if you stay in the west?" Xu Fengxing's voice came from outside the mountain pass. Taking a step, An Xiaoyu saw Xu Fengxing sitting on the stone drinking, and Sanqian Meihua also smiled and nodded.

An Xiaoyu shrugged her shoulders: "The origin and the end are equally important, and other espionage organizations are equally important, but more important is this means. This is a means that can influence the entire battlefield, so can you just leave it alone? Besides, even if they want to take action against the Origin and the End, will they dare to send a master to resist? ”

Xu Fengxing was silent, and An Xiaoyu said it well at all. After this incident, the corpse swindler was inexplicably destroyed, and no one saw it when An Xiaoyu sent Qinglong away, and no one knew what happened in the imperial capital. The origin should not dare to come out and jump again, especially if he doesn't want the master to be killed by An Xiaoyu.

They would rather give up the bases and manpower that are already in the Empire's hands, in order to protect their core members and materials. They know very well that the big war is imminent, and the empire wants to clean up the country, and only when the big war starts, is their chance to fish in troubled waters again.

And last time Qiancao was besieged and injured by the five, and Yu Shou made a tough attack on the alien race, this coward would definitely not dare to appear rashly. The end has always been done behind the scenes, and Qiancao has infinite lives, so naturally he will not be in a hurry, and he will also wait for the start of a full-scale war.

Therefore, the role of An Xiaoyu and Xu Feng is only responsible for probing the other party's location, beware of the counterattack of the masters in the base, and ensure that the army/team of the empire can be encircled and suppressed normally. This is also a means of training the Empire's troops, and the base of origin is full of a large number of strange people, not bad at all with foreign races.

An Xiaoyu can stay in the West for a while, as a divine cultivator, she is the one who has the most hope of discovering the roots of alien methods. Although Xu Fengxing felt that it was very reasonable, the more reasonable he was, the more depressed he became: "That is, if you want to sit here, all the domestic affairs will be handed over to me?" ”

Regardless of Xu Xian's questioning, An Xiaoyu knew that this guy must be troublesome again, and it would definitely be a complication if he said more. Turning around, An Xiaoyu and the three thousand plum blossoms gathered the number of Dao soldiers, and led these people through the no-man's land and headed in the direction of the empire.

In the woods in the distance, several alien races watched the four thousand Dao soldiers disappear into the trees in the distance, and were a little unwilling: "Boss, did you just let them run away?" If the higher authorities knew that we had let people go, they would be blamed at that time...... We'll all have to be sent north to feed the beasts. ”

These aliens looked like dragon fruit, the skin on their bodies was turned out layer by layer to form folds, and their faces were like flowers, with black and orange markings, looking like a mixture of old and new in the pit.

The one known as the boss reminds the burly man that he still has some chappedness on his body, showing his age and defense. Glaring at his subordinates, the boss hated that iron could not be made of steel: "Just you know? Don't I know? But we're the only ones watching here, and as long as we don't say anything, who knows if the humans are gone? ”

"But, won't someone be sent from above to check?"

"Check? Scold! The boss said, "How to check?" It's not that you don't know this place in the Wolf Cry Mountain, but whoever goes in will not come out alive. Who can come out? Let's not say, who would have thought that the human team could be brought out in full? Hell, how did they survive? ”

"Boss, are we going to keep watching?"

The boss turned his hand and slapped it: "Of course you have to continue watching, if you don't watch, who knows if what you said is true or false?" As long as we say we haven't recognized it, and continue to watch here, no one will ever come out of the Wolf Crying Mountain! Shut your mouth shut for me, you know? ”

"Understood! Understand! We didn't see anything! ”

"Yes, there has been no movement in the Wolf Cry Mountain!"

The subordinates nodded like pounded garlic.

The scope of the no-man's land is very large, but the Dao soldiers are all cultivators at least below the Tianxing realm, and the speed of movement is very amazing, even in the jungle and mountains, it is almost a mountain in a moment. An Xiaoyu went to Wolf Cry Mountain in the middle of the night, and before he could wait for dawn, he sent the Dao soldiers to the nearest garrison base.

After handing over these soldiers to the local garrison to rest, An Xiaoyu and Sanqian Meihua returned to Wolf Crying Mountain, and Xu Fengxing, of course, did not want to be with them, and he didn't want Sanyuan Force, so he naturally relied on other people's garrison bases, and guarded the rear in the name of beauty.

Come to the Wolf Cry Mountain again, their speed will be faster, the three thousand plum blossoms are also the masters of the holy realm, the plum blossoms bloom under their feet, one step is ten thousand miles, and in the blink of an eye, the two of them will return to the top of the Wolf Cry Mountain. An Xiaoyu saw this place again, and there was still a large area of disgust in her heart.

"This place is obviously a poison den set up by Heavenly Dao, if I hadn't come, who would have known what was going on inside? A virus that can restrict the laws of the Heavenly Dao and devour all energy, apart from the Heavenly Dao, I really can't think of anyone else who can create it. ”

"Maybe this is also a means for the Heavenly Dao to maintain its own balance." Three thousand plum blossoms said: "The way of heaven itself cannot be perfect, the balance of yin and yang, the coexistence of good and evil, this is the rule set by the way of heaven itself, and it is impossible to violate it, perhaps it is precisely because of this that there is a place like Wolf Crying Mountain." ”

"What did you find inside?" An Xiaoyu didn't want to continue the topic of Tiandao's private life.

Sanqian Plum said: "When we came in, I resolutely hid in the corner. After discovering that there was no alien pursuit, he never moved. But as the platoon commander said before, going to the toilet is difficult. ”

"So I lined up the four thousand people one by one, hand in hand into a line, and then divided the angle around myself. If you need to go to the toilet, ask them to turn it to the other side like a watch hand, and then turn it back when it's convenient. ”

An Xiaoyu was stunned: "You guys are really witty. ”

"It was in the process of moving that one of the warriors at the back said that there was some light in the depths in the outermost part, and I deliberately went over to take a look, and then found that there was indeed a light in the depths of the mist. And the light spreads out, with a kind of law that I haven't seen before. ”

"You haven't seen it either?" An Xiaoyu was a little surprised, the three thousand plum blossoms even knew a little bit about the three yuan forces, and the classics of the three thousand family were even more vast, the three thousand plum blossoms had lived so far that he had never seen them, and An Xiaoyu, a little guy who had only been practicing for a few years, didn't understand it.

However, this did not affect An Xiaoyu's curiosity to see what was inside, a law that had never been seen before, maybe it was the source of the smoke from Wolf Crying Mountain. If you can control this smoke, you may be able to create a mass killing weapon against the alien race.

So the two of them left marks on each other's bodies and promised not to be swallowed by the smoke before they landed on the mountain pass and walked into the smoke of the Wolf Crying Mountain.

And the aliens who were watching in the woods in the distance were stunned, and their subordinates opened their mouths, and they didn't react for a long time: "Old ...... Boss, why are they back? Is there anyone in there? ”

The boss was also a little confused: "Who is it?" Haven't you counted all the 4,000 people who went in and 4,000 who came out? Who else could there be? Can a group of big men give birth in three or five days? Could it be that they found something good in it? ”

"Perhaps?" The subordinates thought it was possible: "Then should we report it?" ”

The boss thought for a long time, entangled for a moment, and said, "Report!" Be sure to report it! Anyway, the realm of those four thousand people is so low, it doesn't matter if they are dead or not, but three thousand plum blossoms and An Xiaoyu, that is the focus of attention above! Report this news and we will have a great credit! ”

As he spoke, the boss couldn't wait to push away the animal skin that was draped over his body for camouflage, and said, "You guys are watching here, I'll go back and report to the lord immediately!" ”

"Boss, go and come back quickly, I'm afraid that they will run away if you come back late!"

"Keep an eye on your pins!"

The alien boss twisted his ass through the woods, and lay on the ground, turning into a large fleshy insect with fleshy skin and orange and black markings, crawling quickly on the ground, the speed was not slow at all, and soon disappeared into the depths of the mountain forest.

At this time, An Xiaoyu and the three thousand plum blossoms had already penetrated deep into the depths of the Wolf Crying Mountain. The two of them didn't fly either, and it made no difference whether this place flew or not, who knows if there are other tricks of the Heavenly Dao on it? So they walked step by step in the direction of the memories of the three thousand plum blossoms.

Sure enough, it didn't take long for An Xiaoyu to see the light passing through, through the misty mist, and the milky white light illuminated a dreamlike space in this gray and cold world. The effect of this light in the smoke is very dizzying, An Xiaoyu waved his hand, but did not push away the smoke around him.

"The light makes the smoke more condensed." An Xiaoyu said softly, and then increased the strength of his hand, but kept it within three meters in front of the two people, for fear of interfering with some of the existences inside. What if this glowing thing is alive and scared away?

So, An Xiaoyu and the three thousand plum blossoms carefully walked through the increasingly viscous smoke towards the source of the milky white light.

At this time, in the laboratory of Jiudaoguan, research on alien shielding methods was already in full swing. Neither of them slept last night, and they disassembled and tested all the experimental samples collected from the submarine and the sting, trying to find out what the other party had used.

Because they don't know where the other party's methods come from, their workload is very large. Rocks, blood, soil, air composition, energy residues, flowers, trees, and mecha wreckage collected at the scene must not be spared, and all must be tested.

Samples from each area had to be compared over and over again, and even the excrement had to be carefully checked to make sure they could find something completely different from all the information they had obtained before, so that they could find out what the other side's methods were.

However, when the Nine Daoguan investigated these materials, it was impossible for the empire to do nothing like this. After careful consideration, Pei Hu submitted a report and proposal of his own to the tripartite meeting at the highest level of the empire, and after the approval of the three thousand families, the court court held an emergency meeting last night.

There were only two items on the agenda of the whole meeting, one of which was immediately adopted by a majority of votes, and people have been sent to the border to carry it out.

Countless soldiers on the border and residents living on the border saw a scene that shocked them when the morning sun shone on the mountain beams. I saw countless cultivators coming across the air, and I couldn't count how many figures there were, and I couldn't tell who they were.

But these people came like a tidal wave from all parts of the empire, some by plane, some directly from a city not far away. The tide converged on the western border, and countless cultivators stood in the air, forming a long, endless dragon that flew to the outside of the western region.

And the soldiers standing at the heads of the various garrisons of the base city saw more.

They saw these cultivators flying towards the no-man's land, flying to the west of the garrison base, maybe their bodies lit up with the light of the law, or they held white jade cards to form a formation, and with their shots, high walls grew out of thin air from the ground.

Such a scene stunned everyone, if it weren't for this time, all the citizens of the empire would not know that there were so many grandmaster-level masters hidden around them, and they would never know that the grandmaster masters of the entire empire were all mobilized to create such a miracle.

Yes, miracles!

In this way, the double-layered walls of hundreds of meters are really like what is written in the essays of elementary school students, growing like mushrooms after rain, uprooting from the flat ground and rising to a height of 100 meters, one by one, one after another, endlessly, forming a Great Wall that surrounds the entire empire and defends the entire west!

In the light of the morning sun, the towering walls covered the mountains and rivers, revealing its broad and burly body, shining in the light as if it were made of gold. And such a high wall is still spreading, from the west of the town to the west and east!

With the movement of the grandmasters, the high walls were connected by dots, relying on the major bases, and crossed the entire western border. And immediately after that, all the military industrial teams of the empire arrived with a large number of helicopters and siege equipment.

In the center of the double wall, a variety of facilities and devices are installed, and sensors are installed on the top and inside the wall, under the corners of the high walls and down to more than 100 meters underground. Whatever means the alien uses to pass through, it will be detected by these sensors.

Anti-aircraft guns were mounted on the walls, elevators were installed in the walls, and walkways were carved out at the top of the walls for mechs and soldiers to patrol. Such a huge project, with the full efforts of the Great Cultivators and the Imperial Science and Technology Industry, took shape in just one morning.

All the Imperial people were shocked, all the Imperial warriors were shocked, even the alien races who were secretly watching the Empire from the other side of the distant no-man's land were also shocked.

The Hong clan is coming, the Huang clan is coming, and countless elders of the higher races stood on the top of the mountain in the distance, looking at the Great Wall that stretched for tens of millions of miles, and they all fell silent. The eastern sun shone on their faces like a slap in the face.

Huang Wuyi suddenly laughed: "This is a human being......"
