Something's Not Right About This Sengoku Japan! ?

I woke up among the cultural relics, but found myself in a completely unfamiliar Warring States Japan. There is no Oda Nobunaga or Takeda Shingen here, there are only countless names that have never been heard of, ruling the roost in troubled times. As a time traveler, he has no system around him, and no divine power to support him. He only relies on a few bits of wisdom from later generations to survive in the strict world. He once wanted to hide in the market, but found that this era never gave ordinary people a chance to stand up. Therefore, he chose to step into the chaos - starting from the lowest level of ashigaru, using strategy as an edge, and climbing up step by step in the blood, fire and power struggle. From giving advice in front of the tent to holding the military talisman, from wandering alone to being in power, the lord he assisted finally became the overlord, but the waves of the times never stopped. When the old reliance suddenly overturned, he clenched the chess game in his hands and looked at the wider sea and land. "Since there is no master in this world... Then it will be up to me to rebuild the mountains and rivers, and even - to create a new empire." Let's see how the little people deal with the parallel Warring States period, break through the situation with wisdom, expand the territory with ambition, and finally embark on a journey farther than the Age of Discovery on the forked road of history.
