Xiao Fan, a modern special operations expert, accidentally triggered his ancestral jade pendant during a mission and traveled to Yingtian Mansion in the fourth year of Jianwen. When he found himself on the bloody battlefield of the Ming Dynasty's Jingnan Campaign, the bound "Destiny Command System" was suddenly activated - he not only had to rewrite history, but also protect a different world that was about to overlap with the Ming Dynasty.
The system gives Xiao Fan the "space-time coordinate" ability, which allows him to travel freely between the two worlds. In the Ming Dynasty, he rose to prominence as a member of the Shenji Battalion and improved fire gun tactics to defeat Zhu Di's cavalry; in the alien world "Xuan Qiong Continent", he unexpectedly inherited the inheritance of the ancient god of war and swept the demon battlefield with modern fighting techniques. As the energy chaos between the two time and space intensified, Xiao Fan discovered that there was a causal connection between the demise of the Ming Dynasty and the resurrection of the devil in another world.
Six beauties with different personalities come one after another: the orphan Jingnan who is proficient in the art of mechanism, the saint of the shaman clan with the power of prophecy, the princess of the former dynasty who was corrupted by the evil spirit, the elf priest of another world, Qianhu, the Jin Yiwei who disguises himself as a man, and the spiritual body "Xiao Shu" who is the embodiment of the system. Xiao Fan was exhausted between the intrigues in the court and the conquests in other worlds, but he did not know that he had already become the key piece to reverse the fate of dual time and space.
When the shadow of the Tumu Fort Incident shrouded the Ming Dynasty, and the demonic dragons of Xuanqiong Continent were about to break through the seal, Xiao Fan held the "Armillary Sphere Blade" that integrated Eastern and Western technology, and launched a final showdown with the demon king of another world at the top of the Forbidden City. Can he open up a third path in the torrent of history? The truth about the reincarnation of two lives is waiting to be revealed by this commander who spans time and space.
