Dream of Immortality

Nowadays, mankind's scientific and technological civilization has reached a certain height. In the medical field, limb grafting, heart transplantation, conjoined heart and lung transplantation, and head transplantation are believed to be successful in the near future. If the heart and lungs can be transplanted conjoinedly, why can't we transplant a few more pieces or even transplant all the internal organs together? Isn't this just a bigger and more complicated operation? But after all, is it nothing more than a surgical procedure? In short, all of this is about wanting to live longer and pursuing immortality. People only know about the rapid development of science and technology in today's society, but do you know how advanced society's civilization was in the Cretaceous Era before the Fourth Ice Age? As early as the Cretaceous Era of the Third Ice Age, human technological civilization has developed to an unprecedented height. In order to fight against the invasion of extraterrestrial beings, Xuanyuan Zhishang estimated that the earth would be destructively impacted by alien planets. After repeated considerations, he resolutely led the most advanced Xuanyuan technology team, riding a dinosaur battle horse, to launch a blocking battle to defend the earth from extraterrestrial beings. After a cosmic war, although a large number of extraterrestrial creatures were repelled and eliminated, the war was too destructive and affected a wide range, causing great damage to the cosmic space in this interface. As a result, the Xuanyuan team jumped from three-dimensional space to four-dimensional space in the endless void. The four-dimensional space and the three-dimensional space are parallel, overlapping, and coexisting three-dimensional spaces. In order to understand the current situation of the earth, Xuanyuan Zhishang launched the "Messenger" project... Purpose: To reproduce the height of social civilization before the Four Ice Ages and the homesickness of space drifters from a new perspective
