In the year of 2XXX, an inventor devoted all his life to develop a backtracking device that was finally tested successfully. Retrospective technology can make an object return to the state before the set time. For example, if a building collapsed five minutes ago, the retrospective time can be adjusted to five minutes and one second before the building is restored to its original appearance. Of course, the longer you go back, the more time you have to react. Backtracking technology can trace back any real object. As long as the operator of the backtracking device has contacted the object, the object can be controlled by the backtracking device. In linear time, in theory, repeated backtracking can make items last forever. At the same time, the use of this technology does not require any consumables. Theoretically, if the core of a piece of equipment is not damaged, it can be used permanently.
Governments of all countries have started to purchase equipment and set up retrospective departments around the world to provide door-to-door services for the public. After this technology has been implemented in a small scale for a period of time, people have seen the endless benefits brought by this technology. Damaged items can be restored, terminal diseases can be cured, and even the dead can be revived. Under this premise, people's demand for backtracking is growing, and the backtracking agency immediately starts to expand the team, purchase more equipment and set up more intensive operation bases.
However, things are not always developing in a good direction. Backtracking services based on institutional practitioners are also facing challenges. With the daily development of retrospective services, some young people are not satisfied with solving existing problems, but start to create problems and find retrospective teams to solve them. Some of them did not hit the target in the game and called the backtracking service. Later, they even damaged public property, deliberately injured themselves, and even committed suicide to seek the "help" of backtracking. These situations were not prohibited by law, so more young people regarded them as the trend.
After the youth incident, some people proposed that this technology should be popularized to everyone. Many social problems will be solved by then. At the same time, more people who are unwilling to call the service or are not covered by the service scope can also benefit from the retrospective technology. Others say that the risk of this technology is as great as its potential, and that it should only be held in the hands of a few institutions that can use it correctly and in compliance with regulations. The risk to individuals is greater than the benefit.
The debate was bound to be fruitless, so the Government organized a referendum. In this referendum, the number of votes supporting the personalization of retrospective technology significantly exceeded that of maintaining the social service model. In the overwhelming support, the government had to reduce the density of local backtracking institutions, demobilize service personnel and mass produce civilian personal version backtracking equipment with weakened functions. The effective duration of the backtracking of civilian equipment is strictly limited, and the use scenarios are also monitored. Each device will be bound to the user's DNA to ensure that the person involved can be found as soon as possible after a malignant event.
But even so, many new social problems are emerging.
No one is willing to work, because money is no longer a problem. If you buy something you like, you can change it back to money directly through backtracking when you are tired of using it. You don't need to think about it again; And broken items can also be made intact through backtracking.At the same time, people who do not have the original capital accumulation are also in an undercurrent. They do not have the money to support the use of the prerequisites for retrospective self-sufficiency. They thought that if they could make good use of backtracking, there would be no negative consequences of illegal actions like robbing banks. At most, they only lose what they got but without imprisonment.
Although the society has been greatly affected by backtracking crime, the actions of the military have really changed the world.
In the inventor’s preliminary calculation,the space can simultaneously contain energy from more than 7 billion peopleoperating reverse devices.
But the inventor will never know that themilitary used reverse technology in WWIII to retrieve the damage caused bynuclear bombs and other WMDs (Weapons of Mass Destruction), including restoringdestroyed facilities, resurrecting soldiers, and clearing fallout. Theunlimited overuse of retracting technology suddenly overloads the depositoryspace.
The massive amount of gathered energy islike a horror monster burst into anger, and it starts to vent its rage to theworld (releasing the energy that is nowhere to be stored). The impact of energyrelease is even more significant than war because the energy release processcombines the energy of countless WMDs and releases them in one particle, so theenergy release has the power and destruction that the highest military power of humankind can not reach. The deadliest is that the energy release may occuranywhere, triggering an unprecedented massive tsunami from the bottom of thesea or destroying half a country instantly. At this time, the military finallystopped, but that was too late because energy far beyond critical value hadbeen crammed into space. The energy release was unstoppable.
Ironically, the technology that had previously benefited humanity had nearly destroyed theplanet in the collapse. Although improper use by the militarycaused this situation, the military did not solve the problem but aimed at thetechnology itself. They hid the truth and said that this was the defect of thetechnology. Uninformed people gathered to crusade against the inventors ofreverse technology, and suddenly the inventor's residence was surrounded. Whenthe inventor is cornered, the military guarantees that as long as the inventoris willing to continue to provide technology for the military, the military canensure the safety of the inventor.
The inventor was taken to a secret base, and all his belongings were then packed and transported to the base. The military examined the inventor's packages in detail, and found a very large backtracking device by accident. The backtracking time on the operation panel was longer than the existing model. To avoid the suspicion of the military, the inventor immediately said that this is a prototype, which has all the functions of the existing model, and the effect and adjustable range cannot be compared as the civilian version and institutional version which designed for safety and cost. As soon as this statement was made, the military immediately proposed to detain the prototype of the backtracking device, on the grounds that the prototype was too powerful and feared that the inventor would betray. The inventor knew that he had no choice but to hand over the prototype and explained the usage information of the prototype. However, he concealed something from the military that the prototype not only exceeded the civilian mass production model in terms of the effective time of backtracking (8 hours for civilian models, 48 hours for institutional models, and 720 hours for prototypes), but also had a function that could directly change the world pattern - time travel.
However, the time travel function of the prototype is only one-way - it can only go back to the past, which means that users cannot go back to the present but can only stay in the past. The inventor intended to go back to the past after improving the civilian mass production version, but the sudden change made him unable to carry out the original plan. He wanted to warn the military not to use the time travel function, but he was afraid that it would remind the military of the existence of Pandora's Box. So the inventor secretly disconnected the circuit of the time travel module and removed the relevant control panel. After some operation, he was relieved to hand over the prototype to the military.
The real purpose of the military is not to protect, but to research. When the military has mastered the backtracking technology, it can threaten the world by monopolizing technology. At the same time, the utility value of the inventor no longer exists. When he is secretly executed, the existence of the powerful prototype becomes a real secret, and it will become the ultimate weapon of the military.
Joyner, the protagonist, who served in the military and was one of the researchers of military backtracking technology. In a military exercise using a beta version of the backtracking technology, the military's imperfect equipment got out of control and directly bounced the energy back to the city. The accident was concealed as an ordinary accidental launch. All insiders were secretly executed. Only Joyner was imprisoned and escaped by luck.
In prison, his family often visited. Butone day, his family never showed up again. After the investigation of theinformant, his home was affected by a small-scale energy leak. After learning thenews, he was so sad that he just wanted to find the culprit as soon aspossible.
Only he knew that this was not an ordinaryexplosion, so he immediately locked the target and embarked on the road ofrevenge.
But is this really the case?

The city looks peaceful, but if people can withdraw something they did in the past?
People can fix broken items by undoing the process it broken, or bringing the dead back to life. Criminals can also withdraw their crimes to escape from being caught.
Crime, now without consequences.During the period when regulations for new technologies were not yet in place, countless riots and wars destroyed the city.

The consequence of the war is not only a destroyed city. To minimize the destruction of the war, the commander drew back the damage of a nuclear bomb. According to the energy conservation law, energy will neither be generated nor disappear. It will only be transferred from one form to another or from one object to another, while the total amount of energy remains unchanged. This means the power of the explosion should be stored somewhere.
The gathering of energy has brought disasters. The power that is nowhere to go has caused many big explosions worldwide. Fortunately, scientists have developed energy recovery devices in a short time. Now they only need death squads, countless death squads, to recycle the energy. Joyner was once a soldier who owned a set of military-grade exoskeleton arm armor. His family died in the explosion, so he decided to be the pioneer.
The first mission was very successful, but when he returned to the city, he found that people hated him. Because after the energy is recovered, the backtracking process which generates power will be erased. Broken things preserved by backtracking will return to the broken state.

When the city is rebuilt, and the criminals taste the benefits, will they stop? The obstruction of ignorant people and stakeholders made difficulties faced by saving the world go far beyond the dangerous environment.
Karl, the sect leader, keeps trying to steal the recycling device to sell on the black market. He also led those people who did not know that the world was about to be destroyed by the energy, and the military who benefited from wars went to prevent Joyner.
When Joyner uses up all the ammunition, and the enemies still don't stop, an abandoned robot, Hades, saves him in the final moments. Joyner then invited Hades to be with him as an assistant.
Their story has just begun. Enemy, partner, the vice city, the truth of the world, the choice of the protagonist, and the end of the world. Protagonist need to choose between saving his family or saving the whole world.
