Douluo Dalu: Martial Soul Mage, Master of the Greatsword

My name is Liu Haizhu. I'm a battle mage, and one day I transmigrated to Douluo Dalu. The instructor who adopted me said that the continent was controlled by the evil Shrek and the Shadow Tang Sect. The Holy Spirit Cult I joined had one mission: to eradicate these two great scourges. As a young man raised under the red flag, I have a duty to uphold justice! That is, until I discovered... My immediate superior is the Demon Empress. Have I... become the villain? But then I saw that Shrek disciples had brazenly attacked a military base, while the Tang Sect was secretly selling weapons in various nations and sowing chaos everywhere. Right and wrong have been turned upside down; black and white are impossible to tell apart. In all of Douluo, could I, Liu Haizhu, be the only one fighting for justice? After obtaining a mage's grimoire, Liu Haizhu can inherit the legacy of a renowned mage from the multiversal Hall of Heroes whenever he breaks through to a new realm. This is how he escaped the Holy Spirit Cult's breeding ground, where disciples were forced to compete for survival. After arriving in Eastsea City and being rescued by Wu Changkong, Liu Haizhu finally sets out on the path of a legendary mage! Shrek Academy: “Once you're in the Holy Spirit Cult, you're in it for life!” The Tang Sect: “You ruined my Tang Sect's ten-thousand-year plan. You deserve to die!” Tang Hao: “The Douluo Plane is my Tang family's backyard. How dare a mere mortal lay claim to it?!” Liu Haizhu: “What are you babbling about? Take this, Comet Azur!” (A mash-up of various mage legacies, including but not limited to The Lord of the Rings, The Witcher, Elden Ring, and The Elder Scrolls.)
