Martial Dao in the Zhenguan Era: I Became a Martial Dao Master by Plundering Cultivation

After transmigrating to the glorious Zhenguan era, Chen Xiao successfully binds himself to a System and gains the ability to plunder the cultivation of the dead! Ninth-rank Skin Tempering, eighth-rank Sinew Training, seventh-rank Bone Tempering, sixth-rank Meridian Opening... Outside Chang'an, on the banks of the Wei River, two hundred thousand armored Turkic horsemen besiege the city. Under cover of darkness, he slips into a mound of corpses and steals the last trace of true qi from their icy bodies. Starting as a lowly laborer who has just transmigrated, he climbs step by step into the upper echelons, wiping out great clans, quelling border threats, and conquering other nations. But after he truly reaches the peak of this alternate-history Tang dynasty's martial world, he suddenly discovers that there is still a path beyond the so-called Grandmaster realm. Every vanished powerhouse points to the same place! The icy wall beneath the far southern sky screen, at the edge of the heavens. That is no so-called edge of the world. It is the true starting point of his transmigration, and the place where the truth behind civilization's cycles lies. What exactly is hidden behind that wall? (PS: This novel combines an alternate-history Tang dynasty with a martial arts system. Some plot elements may not be entirely reasonable, and the protagonist's early rise is relatively slow. If that's not your thing, feel free to skip it after reading the description. One last thing: It's most fun if you don't overthink it!) (Brain deposit box...)
