"Please select the service you need." The female voice in his head continued to sound in Yu Tang's head. At the same time, a string of options was presented before his eyes.

Yu Tang had never encountered such a strange thing. He closed his eyes, and the bars still glowed before his eyes. "Uh...... What is this? Yu Tang asked subconsciously.

For more information on each feature, please refer to the introduction. Plus, you can control the system with your mind, without having to use voice control. A mechanical voice without a trace of emotion replied, and at the same time, a basic operation process manual was also unfolded in front of Yu Tang's eyes.

Only then did Yu Tang realize that he could completely operate this mysterious system with his consciousness. He silently said in his heart, "Open the introduction of the shuttle function." ”

"With the shuttle function, the user can recharge a day in advance and go to the C-level timeline; The user can charge up a week in advance and can travel to the B-level timeline; The user is charged a month in advance and can return to the main timeline. After charging, there is a 12-hour buffer period, and the user can initiate a time travel at any time during the buffer period, but after the buffer period ends, the user will be forced to travel. All shuttles have a certain causal upper limit, beyond which the causal upper limit will not be able to be performed. ”

"What is cause and effect?" Yu Tang continued to ask questions in his mind.

"Cause and effect is the effect of what you do on a certain world line on that world. According to the degree of influence of the current world line, the system will accumulate a certain amount of causal value and set an upper limit of causality. The causal limit is located in the upper right corner of the system and triggers an alert when your causal value is close to the upper limit. ”

Yu Tang then discovered that there is a logo similar to a mobile phone battery in the upper right corner of the system, with a red line on the right side of this logo, and a green square on the left, and a line of increasing numbers above the square.

Yu Tang continued to browse the menu, and suddenly, he noticed a red warning sign in the lower left corner of the system.

With his mind in mind, Yu Tang opened the warning sign.

"The current location is the first branch line of Chronos, the level is B, the danger alert is A, the system has detected that the world line has a tendency to collapse, please leave in time." The content of the alarm made Yu Tang's heart tighten, and he was about to ask more questions when Tang Wangdao's voice came from the living room.

"Son! The meal is ready, come and eat! ”

"Hey! Here it comes! Yu Tang said peacefully. And that system disappeared from his eyes as soon as he gave the shutdown command.

At night, the drunk Yu Tang was moved back to the room by Tang Wangdao. The father and son talked a lot this night, and they both drank too much, Yu Tang's alcohol consumption was not very good, and he was already unconscious after these two taels of liquor. Tang Wangdao originally drank a lot of alcohol, but he saw that his son had finally let go of his mustard heart, and he drank a lot of it with joy. As soon as Yu Tang's head touched the pillow, he fell into a deep sleep.

Nothing was said all night.

The next day, when Yu Tang opened his eyes, it was close to noon. His head was still aching from a hangover. Yu Tang rubbed his temples and walked out of the room.

After washing his face with a handful of water, Yu Tang sobered up a lot. At this time, he recalled the scene of yesterday, and felt like he was in a dream. The system that called itself the key to the time, no matter how much he called in his heart at this moment, did not appear again.

I hope it's a dream, Yu Tang said in his heart.

"Grandma, I'm going to school." After Yu Tang said goodbye to his grandmother, he walked out of the house.

"Hey. When you get out of school, remember to go to the station, your dad went to the town early in the morning to buy New Year's goods, and he had to pick up your mom at the station in the afternoon. Grandma shouted to Yu Tang at the door of her house.

"I know grandma" Yu Tang in the distance waved his hand to his grandmother and walked on the way to school.

When Yu Tang arrived at school, it was already afternoon. Once in the classroom, he went to his seat and went to sleep. As he slept soundly, a familiar voice sounded in his head again.

"Warning! The collapse rate of this timeline is starting to intensify, so please recharge it early. ”

Yu Tang was awakened by this sudden voice, but this time he controlled himself and did not do anything out of the ordinary. The attention of the classmates was still focused on the blackboard, and no one paid attention to the exploding head sleeping in the corner.

"What's the situation?" Yu Tang asked the system in his mind, but the mechanical female voice did not respond to him. There was nothing in front of him at the moment but the big alarm.

Yu Tang didn't figure out the situation for a while, and there was no way to do it immediately, so he turned off the alarm and continued to dream of his big dreams.

After school in the afternoon, Yu Tang and Wang Qu went to the vegetable market as usual, and when they arrived at the vegetable market, Yu Tang found that the entrance of the fruit shop he was familiar with was full of people.

"What happened?" Yu Tang and Wang Qu squeezed into the crowd to see the situation. When they pushed through the crowd, Yu Tang saw Xia Yanqing's crying pear blossom with rain face.

"Hey, Xia Yanqing, what's wrong with you? What about the orange cat? Yu Tang was stunned by this sudden situation.

"It'...... Just died. Xia Yanqing was asked like this, and suddenly cried even more. The crowd of onlookers also discussed at this time, "This cat died too miserably." "Yes, who knew that as soon as Lao Qian's hand flicked, the knife flew over?" "Oh, if it weren't for the cat, it would be this little girl......

Yu Tang squeezed through the crowd, only to find that the little orange had a fruit knife stuck in his head, and his eyes were full of fear, as if he had seen something terrible before he died. And Lao Qian, the owner of the fruit shop, was also sitting on the ground at the moment, with words in his mouth, "I'm sorry, I'm sorry, I didn't mean to ......"

After Lao Qian's sincere continuous apology and Yu Tang's comfort, Xia Yanqing finally calmed down his emotions a little. She pulled out the fruit knife and walked out of the vegetable market with the corpse of the little orange in her arms. Yu Tang said goodbye to Wang Qu and hurriedly followed, ran to Xia Yanqing's side and said, "I'll help you bury it." ”

"Uh......h Thank you" Xia Yanqing was still in sadness, she hugged the little orange tightly, muttering some words that Yu Tang couldn't hear, she was saying a final goodbye to the little orange.

The two found a place near the mountains and rivers, Yu Tang dug a small pit, and Xia Yanqing put the little orange in it. After burying the little orange, the two sat down side by side and chatted aimlessly. Only then did Yu Tang know that Xia Yanqing's mother died of a serious illness shortly after she was born, and her father, who suffered from depression because of her mother's death, also chose to end his life a few years later. They left Xia Yanqing a large sum of money and a small villa, and her father entrusted a loyal old servant to take care of her before he died. Xia Yanqing had already begun to remember at that time, and after being hit by these things, her personality became much more withdrawn, and she also lost the ability to communicate normally with strangers, so she dropped out of school after a few days of school. It wasn't until she grew older and later met Little Tangerine that she gradually came out of the shadow of her childhood and began to slowly try to get in touch with this strange world. But at this point, she didn't need to go to school, because she already had a lot of knowledge far beyond her peers in the library left by her parents. It can be said that this is an existence whose IQ is not inferior to or even greater than that of Wang Qu.

After listening to Xia Yanqing's self-report, Yu Tang finally knew why Xia Yanqing had always been cold to him. At this time, he felt sympathy for this petite girl who was similar to himself and lacked the care of her parents since she was a child.

After he sent Xia Yanqing home, it was already completely dark, and there was a light rain. Yu Tang patted his head, "Ouch, I forgot to pick up my mother at the station." Forget it, let's go straight back. ”

The boy was running towards his home on this drizzly night, and the TV in the window of the shop next door was playing today's news.

"The Eagle Falcon Kingdom officially declared war on the Shenzhou Continent today, and the two sides are currently at war on the border."
