"That's strange... It should be around here."
Xu Ying was in the wild at this time, sitting on a big rock, holding her chin with a depressed look.
"Why can't we find it? It's obvious that only the land here in this area is polluted..."
After coming out of the villa, she made a rough inspection around the city and found that only the area they had just explored was contaminated, while the soil in other areas was still normal.
"The soil is contaminated, which means there must be some special facilities here."
Xu Ying jumped down from the big rock and turned around to look at it.
She touched her smooth chin, then suddenly kicked sideways at the nearly two-meter-high stone.
"Kachcha!"
It was clearly a leg that looked slender and weak, but it suddenly burst out with unparalleled strength. The moment it touched the big rock, the entire rock shattered instantly and then collapsed in all directions.
"Hmm... Not inside either?" Xu Ying showed a slightly tired look, "Where exactly is it? Am I wrong?"
"No, that should be correct."
Xu Ying looked around carefully again: "The center of the entire contaminated area is right here. The source of the pollution must be here... Is it underground? That shouldn't be the case... The transmission device, I remember that a part of it must be exposed."
Xu Ying believes that the reason the soil nearby is contaminated is that someone among the alien invaders buried a transmission device here.
The alien invaders' transmission devices will not cause pollution to the nearby soil when buried, but every time they operate, they will release some pollutants into the surrounding area.
The pollutants that cause land contamination are the waste generated during the operation of the conveyor.
Because the main substances in it have been basically used up, its pollution capacity is not strong, so it will not completely pollute the surrounding land and make the land completely unusable.
But the pollution will gradually spread. The more times the teleportation array is used, the larger the area of surrounding land that is slightly polluted will be.
"Based on the area of this contaminated soil, if it was really caused by the teleportation device, then it would be a bit difficult to deal with." Xu Ying looked a little ugly.
To pollute such a large area of land, the transmission device would have to be activated at least hundreds or even thousands of times!
This number is really scary!
If this is true, it basically means that this most core city of mankind has probably been spied on from head to toe.
and…
This also explains why the guards who suddenly wanted to capture her this time received such an order.
Perhaps some of the upper echelons of humanity here have actually established relationships with the alien invaders on the ground!
There shouldn't be any problem with Wei Bo, and she didn't sense any traces of monsters or mutant creatures there.
In that case, it should be one of the other two... or both of them
"There are more lackeys!"
Xu Ying kicked away the gravel under her feet, clearing a space, but still did not see what she wanted to see here.
"Maybe... I'm wrong?" Xu Ying didn't want to believe her own guess.
If this is true, then she is now in a very passive situation.
This situation is terrible!
She wasn't afraid of what the humans here would do to her, they couldn't hurt her at all, but if it was an alien invader...
That's another situation.
Although she was very proud of her current abilities, she was facing alien invaders who had developed 700 years longer than the monsters that had enslaved her for 300 years and had taken root in the region for 1,000 years...
She really had no confidence.
"You can't think like that!"
Xu Ying slapped her face hard, making it a little red, which sobered her up.
"I am a person with the power of time and space. The only thing that can kill me is this world. Those monsters are nothing! Now I can fight them alone... It shouldn't be a problem to fight them one by one!"
He was clearly trying to muster up his courage, but as he spoke he lost his temper.
She kicked the gravel on the ground with some annoyance, squatted down and hugged her head.
"What the hell is going on? Everything was normal when my brother was here, why did things become so complicated after he left?"
Obviously, she was not responsible for handling the previous issues, but now the problem has become several times more complicated than before, and she is asked to take responsibility...
She can't do it!
"No! I have to cheer up!" Xu Ying stood up suddenly, "Brother gave me the chance to survive, I can't be so depressed!"
She looked around and carefully checked her surroundings again.
Still found nothing.
"My guess should be correct."
Xu Ying began to think seriously.
"I did see a flash of mutant humans here before. The standard color of their equipment meant they were undoubtedly those running dogs."
"If this is where the teleporter is located, that would explain why I saw them here."
“But I really can’t find it…”
Xu Ying looked down at the ground.
"Could it be that he is really buried underground? This is really strange..." Xu Ying stamped her feet and stepped on the ground. "This is already an underground world. If he is buried underground... Can this teleportation array really work?"
"Perhaps... the source of the pollution is not in the center of the contaminated land?"
The polluted area in this region is quite large, and the low shrub vegetation is quite dense, so most of the surface is covered. It is not easy to find a metal pillar that is slightly exposed above the ground in this region.
"I'd better not search for it alone." Xu Ying gave up temporarily. She was still too weak to do it alone. "Let's inform the Wei family and have them search here thoroughly. They must dig deep to find the thing."
"Otherwise, the teleportation device located near the main city area... is too dangerous!"
She looked towards the main city area.
The three tallest buildings are very eye-catching.
"Wei Bo should be done with his work by now, right? Wait... Oops, I forgot to leave his contact information." Xu Ying had a headache.
Then her eyes lit up: "By the way, my sister-in-law seems to have Wei Shishi's contact information! Let's go back first!"
As she spoke, she stepped lightly, a purple-black vortex appeared, and she fell into it, disappearing on the spot.
The jungle is still very quiet.
In order to save time, Xu Ying appeared directly in Li Wenxi's room.
"Sister-in-law, don't sleep, I have something..."
Xu Ying's words stopped abruptly.
She saw that Li Wenxi's bed was a little messy, the quilt was opened, and there was no one on the bed.
"Sister-in-law... is not here?"
The bedroom door was closed but the window was wide open.
"… This is… !"
Xu Ying panicked for a moment.
Could it be that my sister-in-law was kidnapped? !
In this villa, there is indeed a tool with time and space capabilities that she and Xu Xin made together, which can make the humans around them unconsciously stay away from here and prevent them from getting close.
but…
If it was those monsters, or their lackeys...
Xu Ying suddenly lost confidence in the device she made.
She kicked off and appeared at the window almost instantly, looking out.
It was quiet outside, nothing was there.
"No... No way..." She was really panicking this time, "I... I lost my sister-in-law? I..."
At this moment, the door behind her was suddenly pushed open.
She turned around suddenly and saw Li Wenxi walking in with sleepy eyes.
"sister in law!"
Xu Ying's eyes suddenly widened.
"Hmm... Yingying? You're back!" Li Wenxi became much more sober instantly when he saw Xu Ying.
"Sister-in-law, what are you doing?" Xu Ying first breathed a sigh of relief, then complained.
"Ah? I... I just want to go to the bathroom?"
"Going to the toilet?" Xu Ying didn't believe it. "You went to the toilet without making any noise?"
Before Li Wenxi pushed the door open, Xu Ying had no idea of her presence.
With her hearing, it's impossible... She can't even hear footsteps
Li Wenxi seemed to appear outside the door out of thin air.
"No sound?" Li Wenxi was a little confused. "What are you talking about? I just flushed the toilet... Oh, what are you asking?"
"Hmm... Is it because I'm too tired, so..." Xu Ying rubbed her head, "My senses are reduced?"
She walked to Li Wenxi's side and stretched out her hands to pinch various parts of Li Wenxi's body.
"What are you doing... Ah! It's itchy!" Li Wenxi quickly grabbed Xu Ying's hand, "Don't pinch my waist!"
"Yes. She is my real sister-in-law."
Xu Ying even suspected that Li Wenxi had been replaced, but after some verification, she overturned her idea.
If it wasn't Li Wenxi's problem, then it was her own problem.
Her senses, decreased
Could it be that...
Xu Ying's eyes trembled.
Is my time... coming to an end too
"What's wrong?" Seeing Xu Ying's dazed look, Li Wenxi immediately reached out and pulled her face to bring her back to reality.
"Ah... It's okay, it's okay!" Xu Ying shook her head.
No big problem!
She wasn't afraid of death!
Her senses have returned to normal now, there was just a little problem just now, it's not a big problem.
Moreover, there is no time and space disorder around her, so she can at least hold on for a while!
At least we have to solve the problem at hand!
"Sister-in-law, you should be able to contact Wei Shishi, right? I need her help with something."
"Wei Shishi? Oh, sure."
Li Wenxi took out a small device from her backpack: "Is this it? Wei Shishi asked me to wear it on my ear and knock it three times, and I would be able to contact her."
"Yes, that's it." Xu Ying took it immediately and said, "Let me use it!"
She put them on her ears and tapped them three times with her fingers.
The sound of Dudu was immediately heard from the device.
Li Wenxi also put his ear closer.
"Hello, it's me, Wei Shishi." Wei Shishi's voice came over, her voice was as slightly cold as ever.
However, Li Wenxi and Xu Ying both knew that she was a person who was cold on the outside but warm on the inside.
"Ah, it's me, Xu Ying."
“… Why do you have the device I gave to Li Wenxi?” Wei Shishi’s voice suddenly turned several degrees colder.
This is really indifferent.
"Don't be so hostile, okay? I haven't done anything to you." Xu Ying said a little depressed.
"I'm hanging up."
"Hey, don't. I discovered something that concerns the survival of mankind."
“…What’s the matter?” Wei Shishi’s voice became much more serious.
"It's like this..."
Xu Ying told Wei Shishi about her discovery and also expressed her guess.
"You mean to say that the alien invaders have already discovered us?" Wei Shishi's voice was full of shock. "This is impossible! This area is under our Wei family's surveillance. How could they..."
Li Wenxi was also slightly surprised: "So the contaminated soil is because..."
"Forget about your surveillance. I can keep you from noticing if I'm careful. It's too easy for them to avoid your surveillance." Xu Ying curled her lips, "And..."
She had a bad suspicion in her mind.
"And what?" Wei Shishi asked.
Although she was a little annoyed by Xu Ying's disdain for their technology, she didn't dare to lose her temper because it concerned the fate of mankind.
"It's just my guess." Xu Ying looked at the city outside the window. "You have to know that those lackeys of the alien invaders are also human beings. They are humans who survived thousands of years ago, or new humans who were born in these thousands of years."
"...your consciousness says...!"
"Well, perhaps there are already lackeys living in your city, posing as ordinary humans!"
Her words made the hearts of the three people, including herself, suddenly hang in the air.
This conjecture... is a bit creepy.
But, it is indeed very possible!
Xu Ying spoke again: "What I can confirm is that fifty years ago, this area was not polluted. Therefore, the land pollution occurred within these fifty years."
"If the land contamination is really caused by the teleporter, then based on the area, the teleporter must have been used at least hundreds of times, or even hundreds or thousands of times."
"Why place a teleportation device here, and teleport so many times?"
"If it's to infiltrate the city, then it's very possible."
"Those lackeys are teleported again and again just to fit in with the life here."
The three of them were silent for a long time, thinking about the possibility of this matter.
"I have a question." Li Wenxi asked, "Those lackeys all have blood pattern mutation genes, right? If they have blood patterns on their faces and bodies, it won't be easy for them to blend in here, right?"
"The first generation did have blood lines. But blood line mutations are not inherited." Xu Ying explained, "Perhaps it was from individuals in the later generations who did not undergo mutations?"
"It's unreasonable." This time it was Wei Shishi who spoke up. "The population has increased by hundreds or thousands of people for no reason. It's impossible for us not to notice it."
"What if these hundreds or thousands of people entered in stages over the past fifty years?" Xu Ying asked, "If it was a few people per year, would you be able to detect it?"
"Yes. At least in several nearby cities. This is the core area, and we do not allow people without household registration to exist, unless they stay underground and hide away. But in that case, they can't do anything in formal occasions, and even walking will be spotted by the police. Just like you did before."
"I see... It seems that your technology has improved a lot in the past fifty years." Xu Ying thought, "That really doesn't make much sense. But... What if they are not joining, but replacing?"
"Replace... on behalf of...?" Wei Shishi's voice changed slightly.
"Kill them, disguise themselves as them, and live here in their place." Xu Ying said in a deep voice.
"Isn't this... more difficult than the previous one?" Li Wenxi asked.
"Don't underestimate alien technology." Xu Ying shook her head. "Changing a face is too easy. Even humans thousands of years ago could do it. As for fingerprints and genes, as long as ordinary people don't commit crimes, no one will check fingerprints and keep records. So..."
She asked Wei Shishi, "Have you ever heard of some people experiencing drastic changes in temperament, memory fuzziness, or even amnesia? If there are hundreds or thousands of people, maybe there will be some clues, right? Like some strange disease or something like that."
"Yes." Wei Shishi's voice trembled slightly.
"Forget it, if there is none, then there is none... Ah? There is?" Xu Ying's eyes widened immediately, "Really?"
“Yes.”
"Who is it? A lot of people? Anyone you know?"
"My grandfather."
"Your grandfather... ah?!"
