"Has this experiment failed again?" The person who spoke at this time was Li Wei, director of the National Institute of Time and Space, a world-renowned high-IQ scholar who won the Nobel Prize. At this time, although Li Wei was on his back, his spirit was not inferior to that of a young man of thirty. "Elder Li, this is the 9997th experiment that has failed, we have already tried all kinds of creatures, even the people we secretly applied to the state to invite are the same, they were already wiped out before the time sphere reached supersonic speed, let alone the speed of light. It seems that time travel can really only live in novels. At this time, it was a tall OL woman with a pair of women's glasses and a temperament close to perfect. "Who is this talking to Li Lao?", security guard Xiao Wu asked secretly. "You don't know this? Are you a man? This is Li Ying, the goddess of wisdom of our research institute, I heard that she is a top student of Sparrow University of Technology, and her figure and temperament are completely superior to the first-line stars. Security guard Xiao Li boasted, as if he was afraid that no one would know Li Ying. "MIT, right?" said security guard Xiao Wu secretly.

"What the hell did you ignore?" Li Lao pondered as he exited the institute's launch control room.

"Girl, sit down, don't give up your seat, don't look at me old. I killed a tiger when I was young!". That's right, the old man standing in the bus at this time is the protagonist Yang Aotian, a person who likes to brag but is actually very wastewood. But the girl still adheres to the traditional Chinese virtues and gives up her seat to Yang Aotian, who would dare not let a person who is only 100 years old get on the bus. Sit on the bus. Yang Aotian saw the promotional poster of Time and Space Love posted on the side of the road, and fell into deep thought. When he was 20 years old, he had a favorite marriage partner, but he disappeared mysteriously, and when he asked about her parents, he got only a mother's cry and a father's silent bow. After that, Yang Aotian was also married, but his wife was unable to have children and had no offspring, and his wife died ten years ago. Yang Aotian recalled, recalled, and fell asleep directly. It wasn't until the terminal that the driver shouted and got off the bus slowly.

Yang Aotian has a dull life, although his emotions are not smooth, but he has made a lot of friends in terms of friendship. This time I took the bus to attend the funeral of my old friend Li Chao. When he arrived at his destination, Yang Aotian found a place to sit down, and suddenly felt a slight tremor on the ground, but no one else noticed it except Yang Aotian. Suddenly, a voice came to mind in Yang Aotian's mind: "Automatically bind the host for character recognition: Name: Yang Aotian." Age: 98. Potential: D. Based on the foundation: **abundant. Spatiotemporal value: 0. Because the system binding, the space-time value of 1000 is automatically given. Do you want to pick it up?"

Yang Aotian looked stunned after hearing this, and looked around, but no one seemed to hear the voice just now. Yang Aotian silently recited "receive" with questions. At this time, the voice sounded again, "Claimed, do you spend 100 time and space value to travel through time and space?". Hearing this, Yang Aotian was completely blinded, and traveled through time and space? Isn't this what the country has been researching but has not yet succeeded? (because Yang Aotian used to work as a cleaner in the Time and Space Research Institute, so he knew about its existence). But I still chose "yes". The system sounds "Wormhole jump opens, please select a time." At this time, Yang Aotian was overjoyed. He has read so many time-traveling novels, and when he thinks that he can travel to the past dynasty, he can become a rich and rival country, and the scene of three thousand beauties in the harem, his old face smiled lewdly. The system sounds, "Host, please select the time and space where the host exists to jump." Because of the low level of this system, it can only allow the host to replace the host itself in the past space-time, and in the process of jumping in the past, the host of all space-time will be folded and disappear into the desolation." After hearing this, Yang Aotian couldn't help but feel gloomy when he thought that he couldn't go to ancient times and use modern knowledge to master the world. But the thought of being able to go back to the past is also a deep thought. Is it until the youth figure out the truth about Xiaoyu's disappearance? Or directly re-experience life, after all, if you can fall in love when you are a child, there will definitely be many ignorant girls who throw themselves into your arms.

"Wait, since there are 1000 time and space values, and it only takes 100 to travel once, then I can first go to the age of 18 to relive the sweet love of the year, and then to scourge the ignorant girl when I was a child" Yang Aotian made a choice.

"Waste, are you ready to cross? 18 years old?" the system said.

"Yes, wait, who are you scolding, I will be invincible when I go back to the past. As soon as Yang Aotian finished speaking, he directly shrunk into a point and disappeared into this world. A person next to him quickly rubbed his eyes when he saw it, thinking that he was dazzled, "It seems that I should look at my mobile phone less, and I can't even see if there is anyone."
