"Xenogeneous energy? What is that? Lin Chen stopped and asked.

"Xenogeneous energy is bioenergetic that does not belong to the Earth, and may be an alien species." Xiaoya explained.

"You mean there's extraterrestrial creatures on Earth, and they're nearby?" Lin Chen was shocked in his heart, what is the purpose of alien creatures?

"This energy is very weak, maybe it's not an alien species, and biological mutation is possible." Xiaoya added.

"Whether it's an alien creature or not, it looks like we're going to have to go and see it." Lin Chen made up his mind and took a deep breath, his strength was still at the level of a human being, he had not entered the universe level, he couldn't even defend himself with a sword, and if he encountered any danger, he would probably die here.

"Xiaoya, tell me the location."

"Go forward and open the manhole cover." Xiaoya said.

Lin Chen walked forward for a while, and sure enough, he found a manhole cover in a rare place, and observed left and right, but no one passed, so he opened the manhole cover and jumped down.

In the dark sewers, the turbid sewage is full of garbage and emits a foul smell, the light pipes on the walls emit dim light, so that people can barely see the road ahead, and the screams of rats or two from time to time fill the whole sewer with a terrifying atmosphere.

"Turn left ahead, then right at the second turn." Xiao Ya was still guiding Lin Chen forward, and she was getting closer and closer to her goal.

Lin Chen's palms were already covered with sweat, and he carefully observed the surrounding environment. From time to time, the sound of rats or cockroaches being alarmed constantly stimulates his nerves.

Da-da-da-da!

Soon, even the traces of rats and cockroaches disappeared, and only Lin Chen's footsteps echoed in the silent sewers.

"Xiaoya, have you noticed that there are fewer and fewer traces of mice and cockroaches, as if you don't dare to come here." Lin Chen forced himself to calm down, and there was always an indescribable weird feeling here.

"Yes, indeed, we're close to the goal." Xiaoya said.

Lin Chen looked ahead, and on the wall of the road in front of him, some strange brown objects could be seen in the dim light. He lifted his steps and walked up slowly, and when he stood in front of the brown object and saw the whole picture, he frowned, and his stomach was tumbling, and he almost didn't vomit.

"What is this?"

The brown object on the wall resembled the tissues of a living organism, with sarcomas on top of them covered in some dried mucus.

"After scanning, according to the composition, it is very likely that this is the excrement left by alien creatures, and there are remnants of the DNA of terrestrial species in the excrement, including humans." Xiaoya said.

"What? Mankind? You say this alien creature still eats people? Lin Chen said in disbelief.

"Yes, humans are also within its prey range." Xiaoya said.

"Can you find out where this monster is?" Lin Chen clenched his fists and said in a deep voice.

"You can't beat it." Xiaoya gave the answer directly. "This alien creature is most likely an F-class powerhouse."

"F-level, the system will soon be upgraded to level three, then I will soon be strengthened to F-level warriors." Lin Chen said, but he was afraid that if he came back then, he would already let that monster run away.

"Host." Xiao Ya's voice suddenly sounded in Lin Chen's mind, interrupting his thinking.

"What's wrong?" Lin Chen wondered.

"There is a strong xenomorph energy approaching quickly, hurry up and escape!" Xiao Ya's speech speed was very fast, and it seemed that it was indeed very urgent.

Lin Chen ran as soon as he pulled out his legs, rushing towards the original road, even so, the energy reaction was constantly increasing.

"It's still a hundred, seventy, fifty meters away from you......" Xiao Ya kept reporting the distance between the two, which brought huge pressure to Lin Chen.

"Oh no, he's too fast." Lin Chen was already running with all his might, but the other party's speed was much faster than him, and it didn't take long for him to catch up.

"Host, it's three meters to your left." Xiaoya hurriedly reminded her.

Lin Chen's heart froze, and he hurriedly jumped to the right, and then, a powerful impact came, directly penetrating the wall that was several meters thick, and countless huge gravel flew out and smashed on Lin Chen's body, drawing wounds one after another, fortunately he hid in time, otherwise it would not be such a simple matter as a few scars.

After dodging the fatal blow, Lin Chen's body was covered with wounds, he gritted his teeth in pain, and his bloodshot eyes looked at the monster that slowly came out of the darkness.

The monster had a similar appearance to the alien, with black scales covering its entire body, and a huge mouth that was constantly oozing viscous liquid, and there was a hint of heat bubbling from it.

The monster had no eyes, but it had an extremely keen sense of smell, and it was through the smell that it sensed Lin Chen's arrival just now, and then chased after it all the way.

"Host, this is not an intelligent life form, to be precise, it should be a creature bred by extraterrestrial intelligent life, with strong perception ability, be careful." Xiao Ya came to a conclusion after passing the system scan.

"Isn't it a sapient being?" Lin Chen looked at the monster in front of him, but he didn't dare to move easily.

Damn, how could there be such a monster in this underground!

"Xiaoya, can you find a way to escape." Lin Chen asked. He didn't have much hope, the monster crushed him in terms of speed and strength, and trying to escape was comparable to ascending to the sky.

"The system is analyzing the feasibility of escape. Host, let me take control of your body. Xiaoya said.

"Good!" At the critical moment, Lin Chen directly let go and immediately let Xiao Ya take over the body.

"After the analysis, the feasibility is five percent." Hearing this answer, Lin Chen's heart sank, and Lin Chen, who was controlled by Xiaoya, also looked at the monster with a solemn face.

Roar!

The monster let out a sharp roar, and then rushed towards Lin Chen. Lin Chen reacted quickly, and dodged the monster's dash with a rollover, and the opponent's head hit the wall directly, and suddenly smashed a big hole, and the rubble kept splashing out.

After dodging the blow, Lin Chen's hand went deep into the sewage and took out a half-meter-long steel bar, which was found by the system by scanning the surrounding environment and calculating the five percent of the feasibility.

The monster missed the blow, shook its head, and let out a roar that was even sharper than just now, obviously angered by Lin Chen's actions, in its opinion, how could a human, an ant-like creature, resist itself.

Lin Chen didn't face the battle, but turned around and ran, and there was no chance of winning head-on.

The monster also followed closely behind, and then with a kick of his powerful legs, he flew towards Lin Chen, and when Lin Chen rode the monster in the air, he suddenly stopped, his body leaned back for a while, and his hands were tightly grasping the steel bar and thrust towards the monster's abdomen.

Poof!

The monster's body is protected by scales, but its abdomen has no protection, the monster is too confident in its own strength, resulting in this fatal weakness being caught by Lin Chen, and the steel bar is directly stabbed in, successfully injuring the monster.
