Space and Time Debate

In 2043 AD, mankind successfully opened the first controllable space-time channel with the help of the mysterious particle "spacetime". This was supposed to be a milestone in the advancement of civilization, but it instantly led to a declaration of war across time and space from the future. A mysterious force called the "Space-Time Administration" uses dimensional technology that has been mature for hundreds of years to tear apart history and forcibly tamper with the human timeline. The past can be subverted, the present can collapse at any time, and the future is no longer unique. Seven countries around the world were forced to put aside their disputes and transform the peaceful scientific research project "Project Ark" into the ultimate defense system. Lin Shen, a space-time physicist, has become the core chess player for mankind to fight against future forces. He must find the truth in the collapsed timeline and defend the foundation of civilization in countless parallel battlefields. This is not a contest between countries, but a war between the present and the future; it is not a battle for territory, but the ownership of time and space. When time is no longer a one-way river, when every period of history can become a battlefield, the only choice for mankind is to use the present as a shield and science as a spear to start a space-time debate spanning hundreds of millions of years.
