絶対零度 Absolute Zero
What do you get when you combine Battle Through the Heavens (Dou Po Cang Qiong 斗破苍穹), Long Live Summons (召唤万岁), Shen Yin Wang Zuo (or Sealed Divine Throne, 神印王座), Ze Tian Ji (or Way of Choices, 择天记), Vampire Sphere (血族禁域), Douluo Dalu II: Jueshi Tangmen (斗罗大陆：绝世唐门), Coiling Dragon (Pan Long 盘龙), The Celestial Zone (天界无限) and Wu Dong Qian Kun (武动乾坤)? This trashy parody of a martial arts-xianxia-cultivation story, of course!
All Shu Cong wanted to do was learn some martial arts to get a stable career in the military and earn a comfortable income. By some twist of fate, he ends up the disciple of Tian Mo, the legendary Celestial Demon of the evil Heaven and Earth Sect, who is determined to train him to become the strongest exponent in the Hidden Dragon Continent so that he can help take revenge on the other (more evil) sect members and disciples who betrayed him. Unfortunately, Shu Cong wants nothing more than a simple life, and his talent lies more in summoning and not martial arts?!
Warning: no overpowered protagonist and no harem. So...if you think that warrants a 0.5 rating, go ahead. It's just too bad you'll never be able to give me a rating of Absolute Zero!
