Let the system try to save the world

Xitong rushed out of the room in two steps. He pressed the elevator button and while waiting, he called Mu Yiyu.

"Hello, Master?" Mu Yiyu's voice was a little complicated. "Where did you go last night? Are you going to school today?"

"It's not important. Listen to me first." Xitong sent the location to the other party, "Contact your people, something happened."

"Master, I don't know what you are talking about." Mu Yiyu paused for a moment.

"Mu Yiyu, contact your superior immediately. Someone has died here."

“…Yes.” Mu Yiyu had obviously thought a lot in his mind, but his duty as a soldier still made him choose to obey. Even though he didn’t know how Xitong knew his identity, he couldn’t sit idly by and watch the possible danger to the people.

The elevator dinged and stopped on the top floor. Xitong ran down quickly and headed towards the rooftop.

"Wait!" Gu Yugui hurriedly caught up from another elevator. If he hadn't had the habit of exercising, he would have been out of breath by now. "Xitong! What's wrong? Don't just leave others there without saying a word!"

"I told you not to come over." Xitong frowned slightly, "It's hard to explain what's going on here in a few words."

"No matter how dangerous the situation is, it's not your turn as a child to rush to the front." Gu Yugui said in a deep voice, "How can I listen to you if you rush out like this and ask me to stay where I am?"

Xitong frowned and looked at her body that had not yet grown up. "If you must follow me, listen to my instructions later."

"You must have heard news recently about big birds eating people, solitary omegas going missing, strange fish appearing in sewers, cats and dogs going missing..." The two talked as they walked.

"Is there any connection between these things?" Gu Yugui followed closely behind. His unique sensitivity in thinking quickly connected them together. "It's hard for me to imagine..."

"If cats and dogs were taken away by big birds or big fish, I can still understand it." Gu Yugui said, "But what about solitary omegas? No matter how big the bird or fish is, it is impossible for it to drag a person away out of thin air."

Unless the bird is a moa and the fish is a crocodile.

Gu Yugui complained in his heart at an inappropriate time.

"That's the problem." The two walked to the fire door that sealed the roof. There was a big lock hanging on the door, and it was covered with dust. It was obvious that no one had been there for a long time.

"How do you explain this?" Gu Yugui held the lock and weighed it. "If you said the person who took the omega away is up here, did he fly up here?"

"When did I say that the one who took the omega away was a human?" Xitong tried to hold the iron chain that was as thick as a baby's arm. He exerted force hard and the chain made a teeth-grinding squeaking sound. Xitong wrapped the chain around his hand twice, and with a crisp sound, the chain broke.

"You..." Gu Yugui opened his mouth, "Can't you break the lock?"

He cursed inwardly that his thought circuits had been assimilated by Xitong. In this situation, shouldn't he ask the hotel staff for the key?

"I need it." Xitong wrapped a one-meter-long chain around his wrist, holding one end of the chain in one hand. He pushed open the door and ran quickly, "Follow me."

Gu Yugui could never have imagined that one day he would be parkouring on the rooftop of a hotel with a young student he had just met. The student would stop from time to time to sniff the wind, and the iron chain on his wrist -

Gu Yugui had the illusion that he was walking the dog.

Just think of it as playing with the child, Gu Yugui comforted himself.

"There is a creature whose upper body is a bird and the lower body is a fish." The two stopped beside a large water tank. Gu Yugui's face looked a little ugly. He covered his nose. It was midsummer and the smell coming from the water tank made him have some bad guesses.

Xitong gently poked Gu Yugui's waist and pointed to the corner of the parapet. Gu Yugui's eyes narrowed. There were several corpses of cats and dogs. Except for the vaguely visible fur, the internal organs and meat had been eaten away by something.

Gu Yugui clearly saw a kitten lying on the ground with a name tag hanging around its neck. Its fur was snow-white, and even though the recent wind and rain made it no longer so beautiful, it was still recognizable as someone's favorite.

Gu Yugui looked away. He grew up with his grandfather in the countryside. Dogs in the countryside were more like family members than pets. He also had a pet dog now. Gu Yugui could not imagine how devastated and painful the owner of the white cat would be if he saw the miserable state of his pet.

"What is that?" Gu Yugui said softly.

"Gu Diao." Xi Tong looked up and saw a black dot growing bigger next to the sun in the sky. He took a step back, tightened his grip on the chain, and took a fighting stance. "Be careful, hide."

"Didn't you just ask me how those omegas disappeared in plain sight of everyone?" Xitong swung the chain in his hand vigorously. The water tank in front of him made a buzzing sound after being hit by him. The black spot was obviously angered and approached quickly.

"They walked out on their own." Xitong shouted, "Cover your ears!"

The black dot screamed, and the sharp sound gradually became lingering and sad, like the whisper of a lover. Xitong swung the chain and pulled it again.

A corner of the water tank burst, and a large amount of sewage flowed out through the crack. The strong smell almost made Gu Yugui vomit. He was about to collapse. Many hotels collect rainwater and purify it for customers to use. It seems that they used the water in this tank for washing yesterday!

"Xitong, Xitong..." Three chubby little kids ran out of the water tank. They looked very much like the kids they had handed to the two yesterday. They jumped and jumped, looking at Xitong with sad eyes, "Are you going to kill us?"

Xitong rushed forward and kicked one of the children to the ground. He picked up the arms of the three children like a string of candied haws. He seemed to be deaf and tied them together with iron chains amid the children's screams and cries.

"What is this!" Gu Yugui roared uncontrollably. From his perspective, three monsters that looked like both birds and fish rolled out of the water tank, making sounds similar to babies crying. They had bird claws and fish scales under their shoulder blades. Xitong was tying them together by their wings.

"We hate you!" the child's tender voice repeated again and again with resentment, "We hate you!"

"I curse you..."

"I curse you to be alone! I curse you to be alone forever..."

"It's written in the Classic of Mountains and Seas, 'Its shape is like an eagle with horns, its voice is like that of a baby, and it eats people.'" Xitong threw a few little Gu eagles and slapped them in the face. They soon began to shiver quietly in the corner. "These are still Gu eagle cubs, and their horns haven't grown yet."

As the water flowed out, Gu Yugui also saw the source of the stench. It was a beautiful omega. Even though he had been soaking in this dark water tank for who knows how long, one could see his soft bones. His eyeballs had been eaten by something, but his face was peaceful, and even had a hint of joy.

His chest and abdomen had been hollowed out, with only his white ribs exposed. Gu Yugui couldn't help it, so he knelt on the ground and vomited.
