These xenomorphic creatures gathered in groups, no queue, no order, just sitting quietly on the ground, looking up at the stars in the sky, chanting and singing a sacred tone. At this time, the xenomorphic creatures no longer have the appearance of beasts, but give people a quiet and far-reaching appearance like a monk.

Zhang Lan and Li Junshan saw from a distance a large number of xenomorphic creatures singing a chant-like tone, and they were shocked and speechless by the huge contrast between darkness and light, depravity and redemption. But shock is shock, they have not forgotten the purpose of this trip after all.

Taking advantage of the fact that the alien creatures were performing their rituals, Zhang Lan and Li Junshan quietly sneaked along the ridge to the corner between the outer wall of the castle and the mountain. Although I have heard Lily talk about the outer wall of this castle, I can only experience its majesty when I really stand at the foot of this city wall: huge rocks are stacked together along the trajectory demarcated by the city wall, chaotic but tightly stacked, these rocks are large and small, the big ones are sixty or seventy meters high, and the small ones are fifty or sixty meters, although they are messy, but one side of the sharp corners of these rocks is outward without exception, and from a distance, it looks like a battle formation lined with giant spears, and above these huge rocks is a corridor built with wooden supports, This corridor was used by xenomorphs to patrol the outer walls, but there was no one on it.

"I really don't know how these alien creatures like Wu Dalang built this city wall, do they also have cranes?" Li Junshan, who was drilling under a boulder, looked at the outer wall and said suspiciously.

Li Junshan ignored him, he was thinking about how to climb over this city wall. The boulders, though cluttered, have no gaps, and the sharp corners that slope outwards leave no room for them to climb from the bottom up.

Guessing Li Junshan's troubles, Zhang Lan took out the dragon skin rope he used to climb the mountain from his backpack, and Li Junshan, who saw the rope, couldn't help but light up. The rope is about thirty meters long, and there is a stone tied to one end. Seeing this stone, Li Junshan looked at Zhang Lan and asked in a low voice: "There are stones everywhere, you still carry such a piece on your back, isn't it heavy?" And Zhang Lan, who was looking at the stone, also smiled awkwardly, "I forgot it when I packed it."

With the rope, the problem is easy to solve, the two of them found a place where the two boulders were stacked at the corner, threw the end of the stone tied to the corner and stuck it, the two looked around, and after finding no alien creatures, the two quickly climbed the boulder along the rope, stood on a protruding sharp corner, and threw the rope to the second layer, and then climbed the rope again, and this time they had already climbed to the top of the city wall. The two climbed a height of more than 50 meters twice, and the two spent less than five minutes in total.

Sneaking under the wooden hallway perched on top of the boulder wall, the two glanced at each other. Together, they jumped off the city wall, landing with only a slight sound, and the two of them landed safely on a long gravel street that surrounded the outer wall.

Inside the outer wall, it is really the same as the situation said by Lily, a castle-shaped mountain castle with the castle as the center and the long gravel street as the skeleton jumps in front of you, and the classical and elegant houses are neatly arranged between more than a dozen long streets, and they are like the castle Relying on the mountain behind them to radiate in a semicircle, compared with the modern city, the whole mountain city is elegant and exquisite, and the settlement outside the wall seems to be two worlds.

Zhang Lan, who was still shocked by the difference between outside the city and inside the city, was pushed hard by Li Junshan behind him at this time. Now is obviously not a place to be shocked and in a daze, Zhang Lan gave Li Junshan an apologetic look, and quickly strung into the shadows of a house. The two weave their way between houses and in the shadows. If you don't already know that this is a city of completely different species from humans, the two people who walk through it have the illusion of traveling in a small European city, not only the roads and houses, but even the sewer system and urban layout are completely the same as in Europe, but I don't know if it is because of the xenomorph creature ritual, the xenomorph creature in this small city is extremely rare, they have been going around the city for a long time and have not seen a cloth-clothed xenomorph creature in Lily's mouth, and occasionally they can see a fleeting shadow from the house that transmits bright light, It will let people know that the city is still inhabited by creatures, not a ghost town. Therefore, Zhang Lan and Li Junshan's actions were a little unscrupulous in their own eyes, and after traveling for more than an hour, they finally approached the inner wall of the castle that Lily said.

The inner wall of this castle is the same as Lily said, and the style of the whole city is completely different, the whole presents a feeling of a quaint Chinese city tower, there is an arrow buttress every distance on the city wall of more than 30 meters high, but there is no soldier on the city wall at this time, and the black city gate decorated with door nails and knockers still has traces of a large area of explosion, and there is no one guarding it at this time.

Across a long gravel street that surrounded the city wall, Zhang Lan and Li Junshan hid in the shadow of the corner of a house, staring at the city wall with doubts in their eyes, they were now both excited and scared, excited that they were only separated by a wall from the human beings that Lily said. And what they are afraid of is that their infiltration operation this time is too smooth, except for some forks in the waterfall, this way can be said to be unhindered, their original plan was to only do reconnaissance tonight, and after having an all-round familiarity with this xenomorph creature gathering place, they are choosing the opportunity to carry out a rescue plan. But today's investigation is too smooth, and it is beyond their imagination, even if there are no guards in such a city, there should at least be guards, but now not to mention that there are no guards, so it is a little weird that it is smooth.

"What should I do, can't I get in?" Zhang Lan asked with a sad face.

Li Junshan did not immediately answer Zhang Lan's question, she leaned on the unusually neat walls of the house that were also built with stones but were polished, and thought for a while. "In this situation, it may be that this gathering place of xenomorphs is not able to threaten their enemies for the time being, so the defense of the entire city is relatively lax, and at the same time, the defense of their city is obviously not designed for us. The two of us are actually outliers to these xenomorphs. To put it bluntly, the physical fitness of the two of us is more than a step higher than that of ordinary people, even compared to these xenomorph creatures, and the tall outer wall is not something they can climb according to the physical strength of the xenomorph creatures, let alone this thirty-meter-high inner wall, and these are not problems for us, so our actions now seem to be smooth and abnormal, which also shows that our understanding of the changes in our bodies is not very clear. And one of the reasons why we came in during the race ceremony of these xenomorphs was also so smooth, otherwise the outer wall and the inner city patrol xenomorph soldiers that Lily said would not be something we could handle.

"What do you mean, let's continue to carry out the rescue plan," Zhang Lan asked hesitantly.

Li Junshan hesitated for a moment and said: "I think we should continue the rescue plan, not to mention whether there will be such a chance in the future, let's just say that after the four patrol xenomorph creatures we killed today are discovered, it will add many unknown variables to our future coming." In addition, the most important point is that according to Lily, the gorgeous cloth robe will basically eat one person a day, and it seems that he will increase the amount of food after he is injured, if we delay some time, I don't know how many targets we have left to rescue.

"Okay, let's do it" Hearing Li Junshan's last words, Zhang Lan's hesitant expression disappeared instantly, and was replaced by a resolute look on her face.

Seeing Zhang Lan so simply, Li Junshan also smiled slightly. She picked up a stone beside her, looked in one direction of the city wall, and threw it, hitting a stack of arrows, and then bounced onto the wall with a thud. At the moment of throwing the stone, Li Junshan quickly pushed Zhang Lan into the shadowy depths of the wall. After about three minutes, after seeing that there was no reaction on the city wall, Li Junshan glanced at Zhang Lan, and then quickly rushed to the city wall, and jumped hard when he was about to approach the city wall, this jump was more than ten meters high, when she was almost exhausted, she kicked the city wall and jumped up nearly ten meters high, after borrowing strength on the city wall for the second time, she had jumped on an arrow battlement, the whole action was done in one go, and the action was clean and neat and indescribably handsome and chic. The moment she touched the battlement, she quickly flattened her body and hid her figure. After a while, Li Junshan did not notice anything abnormal, and only then did he show his head from behind the arrow stack and make an "OK" gesture to Zhang Lan. Seeing this, Zhang Lan did not hesitate, followed Li Junshan's example, and jumped up through the city wall. He has much more strength than Li Junshan, so he only borrowed strength on the city wall once, and climbed the city wall, but his skills are not the same as Li Junshan's whispers.

Li Junshan hurriedly supported Zhang Lan, and the two climbed on the other side of the city wall together and looked into the courtyard of the castle.

Relatively high walls, the courtyard between the castle and the city walls is disproportionately small. The arc between the city wall and the castle is squeezed into an irregular trapezoid, and the courtyard is also paved with gravel, exuding a leisurely cold glow in the dazzling light of the galaxy, but the huge castle is like a shadow in the starlight, which is distorted in Zhang Lan's eyes and looks very unreal. On one side of the city wall in the courtyard is a row of huge cages like birdcages. Sure enough, as Lily said, the city gate divided the birdcage into two, and the human beings imprisoned on the right side of the city gate were clearly reflected in Zhang Lan's eyes.
