I used space to carry a lot of supplies to escape famine in ancient times

Gu Qianning and Chu Mohan's lives gradually became stable. They used the large amount of supplies carried in Gu Qianning's space to not only help themselves survive in the difficult environment, but also provided a lot of help to the people around them, and also had a certain influence in the local area. However, by chance, they came into contact with some mysterious records about time, which aroused their strong curiosity and desire to explore. So, they decided to start a bold and unknown research project - time travel research, trying to explore the mysteries and possibilities of time.

One day, Chu Mohan accidentally found a tattered ancient book in an ancient market. The paper of the book had turned yellow and the handwriting was a little unclear, but Chu Mohan was attracted by some of the strange descriptions about time. He couldn't wait to bring the book back to Gu Qianning, and the two of them read it carefully together.

The book mentions some time distortions, space-time cracks, and possible methods and signs of time travel. These contents are like fairy tales to them who lived in ancient times, but they are full of irresistible charm. Gu Qianning and Chu Mohan are both adventurous and curious people. In the context of modern society, they have deeper thoughts and imaginations about these mysterious phenomena.

"Qian Ning, what do you think it would be like if time travel is really possible?" Chu Mohan's eyes flashed with excitement.

"I don't know either, but I feel that this will be a discovery that can change everything. However, it is definitely full of unknowns and dangers." Gu Qianning said excitedly but also a little worriedly.

Although they knew that time travel involved many paradoxes and dangers, their determination did not waver. They began to collect all the information related to time, whether it was ancient legends, mysterious relics, or some seemingly absurd folk tales. Gu Qianning used her space to properly preserve the collected information so that she could consult and study it at any time.

In order to conduct research better, they also built a simple laboratory. Chu Mohan used his manual skills to make some simple measuring tools and experimental devices. Although these tools are very simple compared to modern scientific instruments, they are the best they can do in this ancient environment. Gu Qianning is responsible for organizing and analyzing the collected data, trying to find some patterns and clues from them.

After conducting an in-depth study of the collected materials, they found that time also has different interpretations and understandings in ancient philosophical and scientific concepts. Some ancient philosophers believe that time is a flowing, irreversible force that dominates the birth, death and change of all things; while others believe that time is a relative concept, and its speed of passage varies depending on the observer's state and environment.

Gu Qianning and Chu Mohan combined modern physics knowledge with these ancient concepts and began to construct their own time travel theory. They believe that time may not be as linear and single as we intuitively feel, but there are multiple dimensions and possibilities. Perhaps under certain special conditions, time and space will be distorted, forming a channel connecting different time points, which is the possibility of time travel.

In order to verify their theory, they conducted some preliminary experiments. They set up some simple observation devices in a remote valley, trying to capture possible time anomalies. Every day, they would come to the valley and record various data, such as magnetic field strength, air humidity, temperature changes, etc., hoping to discover some time-related laws.

However, as the days passed, their experiments did not make significant progress. Most of the observed data fluctuated within the normal range, without the abnormalities they expected. This made them feel a little frustrated, but they did not give up. They knew that scientific research often takes a long time and a lot of attempts to achieve a little breakthrough.

In the process of research, time paradox is an unavoidable problem. They know that if time travel is really possible, it may cause a series of paradoxes, such as grandfather paradox, butterfly effect, etc. These paradoxes are not only difficult to solve in theory, but also may bring unexpected consequences in practice.

The grandfather paradox is one of the most famous. Suppose a person travels back in time and kills his grandfather before he gets married and has children. Then this person himself will not be born, and it is impossible for him to travel back in time to kill his grandfather, which forms a logical contradiction.

Gu Qianning and Chu Mohan often fell into deep contemplation in order to think about this problem. One night, they sat under candlelight and discussed this paradox again.

"Chu Mohan, what should we do if we really encounter a situation like the grandfather paradox?" Gu Qianning asked with a frown.

Chu Mohan was silent for a moment, then slowly said: "I think we can't simply understand this problem from a linear perspective. Perhaps in the process of time travel, time is not as absolute and unchangeable as we are familiar with. Perhaps every action we take will create a new time branch, rather than directly changing the history that has already happened."

Gu Qianning listened to his words and nodded thoughtfully: "What you said makes sense. Perhaps we need to re-examine the nature of time and our relationship with time. However, this also means that every decision we make may bring unpredictable consequences, and we must be very cautious."

In order to deal with possible time paradoxes, they decided to formulate a series of rules and plans before conducting time travel experiments. They imagined various possible situations and formulated corresponding countermeasures. For example, if they encountered a situation that conflicted with their own or others' past during time travel, they would try to avoid directly intervening in historical events, but instead adopt the method of observation and recording to reduce the impact on the timeline.

After a period of hard work, their experiments finally yielded some unexpected discoveries. During one observation, they discovered that the magnetic field strength in a specific area of ​​the valley had experienced abnormal fluctuations. The pattern of this fluctuation was very strange and different from any natural phenomenon they had previously recorded.

Gu Qianning and Chu Mohan were very excited. They thought this might be a sign of time distortion. They immediately conducted a deeper study and exploration of the area. They used some homemade instruments to try to measure the specific parameters and changing patterns of this abnormal magnetic field.

As the research deepened, they found that the passage of time in this area seemed to have some subtle changes. In this area, some plants grew significantly faster than the surrounding plants, and their growth direction was also somewhat abnormal. These discoveries made them more convinced that they might have found the key clues to time travel.

However, just as they were excited about these discoveries, a crisis quietly arrived. One day, when they were conducting experiments in the valley, a strange light suddenly appeared in the sky, followed by a powerful energy wave. Before they could react, they were swept into it.

When they woke up again, they found themselves in an unfamiliar environment. The surrounding scenery became blurred, and time and space seemed to have lost their original order. They realized that they might have accidentally triggered some kind of time distortion phenomenon and entered an unknown time domain.

In this unknown time domain, Gu Qianning and Chu Mohan felt unprecedented fear and confusion. They didn't know where they were, nor how to return to the original timeline. Everything around them seemed so strange and weird, and the passage of time became extremely unstable. Sometimes it felt like time was passing quickly, and sometimes it seemed to be stagnant.
