In the Fruit World, martial arts are the most sought-after pursuit! Among them, the Righteous Sect founded by the Fruit Heroes—Orange Stay, Pineapple Blowsnow, and Little Fruit Lu—stands out the most. Known as the Three Fruit Swordsmen, they roam the Fruit World, upholding justice, fighting the strong to protect the weak, and are worshipped by the masses. However, during the third-anniversary celebration of the Righteous Sect, the Four Evil Villains suddenly appear, defeat the Three Swordsmen, transform the Righteous Sect into the Wicked Sect, and proceed to eliminate other sects, capture villagers, and plunge the Fruit World into chaos and suffering. To save the people and restore the Righteous Sect, with the secret help of the eccentric Feng Qingyang, the Three Swordsmen defeat monsters to obtain divine weapons and upgrade their mechas. They advance toward the lair of the Four Evil Villains, and along the way, they share a series of hilarious, passionate, and comedic adventures with Shangguan Ziyi, Little Fruit Ding, Ye Yan, and others. Each arduous battle becomes a step in their growth, and with unwavering perseverance and an indomitable spirit, the Three Swordsmen finally defeat the Four Evil Villains and reclaim their peak. Just as the Three Swordsmen believe the crisis is over, the mastermind behind the Four Evil Villains—Dongfang Qiubai—emerges! Faced with Dongfang Qiubai and the Four Evil Villains, who seek to overthrow the Fruit World, the Three Swordsmen, along with Feng Qingyang and others, engage in an earth-shattering battle at the Lotus of Seven Realms Mountain—a fight that determines the survival of the Fruit World. In the end, the Three Swordsmen and their allies perish together with Dongfang Qiubai and the Four Evil Villains, using their lives to protect the Fruit World.
