Civilization in Five-Dimensional Space

The world has just experienced the Third World War. The Shanghai Cooperation Organization, composed of Russia, China, North Korea and other countries, and the Western powers led by the United States have been fighting for thirty years. Contrary to the predictions of many people before the war that nuclear war would destroy the earth, nuclear war was not used during the entire war. Maybe both sides knew the consequences. However, except for a few big countries, their own territories have not been seriously damaged. For example, the Bund in Shanghai remains the same as it was before the war. But many hotspots no longer exist. Both sides use precision to strike military targets. The active-duty soldiers on both sides were basically wiped out. Forced by desperation, the powerful in various countries also made major reforms and significantly delegated power and benefits to the people at the lower levels. Although the death toll in this world war was not as expected. However, the slightly valuable scientific and technological facilities, factories, military bases, etc. On both sides have been basically wiped out in the madness of both sides. In other words, in addition to nuclear bombs and people on both sides, human civilization has also returned to its primitive state. A large number of technical personnel were conscripted into the army, and almost all of them died. What is left in the world are some so-called government members who hide hundreds of meters underground and dare not show their faces, and civilians on the ground who are not qualified to be involved in the war. I was one of the survivors. When the recruitment notice was sent to him, he disappeared into this 5-dimensional high-dimensional space world the next day. After the war, I strangely returned. The following is the article I wrote when I returned. It can be taken seriously, or it can be considered a fantasy hallucination on my part for entertainment purposes only. Purpose: Through the protagonist's research, mankind has entered an epoch-making era of high-dimensional civilization
