Is the Earthquake Fruit Very Damaging? Don't Look for Me to Destroy the Country

This world, which was originally technologically prosperous, was invaded by alien beasts due to an accident. Humans also gained Devil Fruit abilities as well as super powers such as Haki, Six Styles, and Swordsmanship. Yang Qian traveled to another world, awakened the power of the Zhenzhen Fruit, and became the first SSS-level ability user in Snow Country in history. Inheriting his father's legacy, he guarded the frontier for ten years. Because of his presence, the alien beast front line was reduced by thousands of miles, in exchange for the long-lost peace of mankind. But because of a confrontation with a strange beast, he accidentally destroyed the castle of Princess Xia Lingling of the Snow Country, and was sent to the trial court for ability users! "Yang Qian, you destroyed the princess's castle, do you think you are guilty?" "I killed a hundred thousand strange beasts!" "Yang Qian's evidence is conclusive. He is in contempt of the court and the princess. He is sentenced to be expelled from the Snow Country!" Yang Qian: "Okay!" … After Yang Qian left, the alien beasts began to invade on a large scale. When the other SSS-level ability users in the Snow Kingdom were instantly killed by the King-level alien beasts, everyone thought again of the young man with the power of the Shock Fruit. So, the king of Snow Kingdom took the princess of Xia Kingdom to Yang Qian's residence to ask for help. Yang Qian's answer is: "No! My Zhenzhen Fruit is said to be very destructive. You should deal with this strange beast yourself." That day, Heavenly Kingmon broke through the Snow King's castle! The Snow Country was declared destroyed, and everyone in the Snow Country cried bitterly and regretted it!
