Maoshan's Martial Madman: The Sacred Heart Art from the Start

(The rating was just posted, so it may rise later.) Lu Xuan transmigrates into a world of zombies. When he joins Maoshan, he is told that his cultivation aptitude is only mediocre and that he has no hope of attaining immortality in this life. Just then, his Martial Arts System activates. He resolutely switches to martial arts, and the System grants him a peerless martial physique. The moment it fuses with him, the phantom of a Martial God appears, stunning all of Maoshan. The sect leader personally offers to take Lu Xuan as his personal disciple. To his surprise, he becomes Ninth Uncle's junior brother and the youngest junior grand-uncle in all of Maoshan. [Ding! Congratulations, Host, you have obtained the martial art “Sacred Heart Technique.”] [Ding! Congratulations, Host, you have obtained the martial art “Heaven's Will Four Symbols Technique.”] [Ding! Congratulations, Host, you have obtained the martial art “Heavenly Blade Eight Forms.”] [Ding! Congratulations, Host, you have obtained the legendary martial arts tome “War God Catalog.”] Everyone believes that the path of martial arts has long been severed, and that Lu Xuan was born at the wrong time, doomed to never break through to the Grandmaster realm. The next moment, right before their eyes, Lu Xuan uses the Indestructible Diamond Art to transform into a golden figure. With his Dragon Elephant Prajna Skill mastered to the highest level, he tears a flying zombie apart with his bare hands. Lu Xuan: “Senior Brother, your Lightning-Fast Thunder Fist isn't fast enough, and it sure isn't ruthless enough. Behold, my Emperor Tian's Mad Thunder!” “Senior Brother Simu, hurry up and perform the Spirit-Summoning Rite. Let's have a real man's battle!”
