Magical Japanese Warring States Period, My Shikigami Is the System

Shangguan Yangming traveled through time and came to Japan's Warring States Period in the twelfth year of Yonglu. His portable system told him: By killing enemies with soul power and shikigami, you can plunder their soul power and shikigami power and strengthen yourself. In the system prompt, Yang Ming only saw a few bloody characters, which were "kill people and seize souls". To collect soul power and shikigami, Yang Ming needs to constantly kill enemies. Only when the system becomes stronger can Yangming continue to be strong. The Warring States Period in Japan in another world is an endless hell soaked in blood and betrayal. On the archipelago, daimyo gathered their troops to chase deer, fallen warriors gathered in the mountains and forests, and fierce bandits and bandits roamed the countryside. Every inch of land is soaked in the blood of wronged souls, every sea breeze is filled with the smell of killing, and the entire Fuso Islands has been reduced to a dark forest where the weak and the strong prey on each other. This hell on earth is more cruel than reality. Demons are rampant in this space and time, the secrets of yin and yang are completely out of control, and everyone in the samurai can awaken the "Shikigami". Shikigami are either ferocious ghosts spawned by resentment in troubled times, or spirits and monsters preserved from ancient times, or alien monsters from the underworld that cross the border. The secret techniques of servitude passed down from generation to generation by the Yin Yang family were scattered across the island with the collapse of the shogunate, and became a weapon for samurai to fight for power and massacre. Shangguan Yangming, a male college student from modern China, accidentally traveled here. He has no prominent family background and no powerful influence, only his own shikigami system. Surrender powerful generals, kill bandits, gather friends, save the common people, wake up to take control of the world, and lie drunk on the knees of beautiful women. Use the system as a sharp blade to cut through the fog of troubled times, crush the Fuso chess game, quell the wars of the country, and create a legend of overlord that is unique to you.
