Navigation: Guard the Upside Down Mountain and Stop Kaido at the Beginning

Soma traveled through the world of pirates and accidentally awakened the Moriyama System! As long as you stop the enemy at the foot of the mountain and complete the defense, you will receive generous rewards! Following the death of Whitebeard, the old era ends and a new era begins! Tens of thousands of pirates will enter the Grand Line from Upside Down Mountain, looking for the one piece of the unknown secret treasure! But when they arrived at Upside Down Mountain, they were all dumbfounded! I saw Soma with his hands in his pockets, as if he didn't know what his opponent was, and he stopped the Yonko by himself! "Stop Kaido, the strongest creature, and reward him with the body of a divine dragon!" "Stop BIGMOM and reward God for avoiding it!" From then on, Soma was out of control. "Stop Straw Hat King Luffy and reward him with swordsman-level swordsmanship!" "Stop Blackbeard Tikki and be rewarded with the God's Slash!" "Stop the blind swordsman Fujitora and reward you with the Holy Sword of Light!" "Stop the red dog Akainu and reward you with the sword of justice!" "..." At the end of the guard period, Sumoti Sword stepped out of the Upside Down Mountain, and the entire sea trembled! This novel and its characters are purely fictitious.
