My Senior Brother and Sister Have Sacred Bodies, but I'm Just an Ordinary Junior Brother

Chu Fan has a rather unreliable master, who passed down to him the Nine Tribulations Mortal Extremity Art! Endure nine tribulations, pursue the limits of the mortal body, and achieve eternal immortality! Mortal flame tempers the heart, awakening the Mortal Extremity Dao Heart: immune to illusions and astonishingly quick cultivation! Dark ice seals the marrow, awakening the Mortal Extremity Origin Blood: immune to all poisons and capable of extraordinary recovery! Duel with the heart demon, awakening the Mortal Extremity Clone: split into two, doubling your combat power! Ghosts wail in the Nine Abysses, awakening the Mortal Extremity Divine Soul: an unbreakable soul, unafraid of evil spirits! The earth collapses and mountains crumble, awakening the Mortal Extremity Battle Bones: indestructible, undefeated as long as I stand! Lava burns the body, awakening the Mortal Extremity Elixir Sea: endless spiritual energy, containing boundless power! The Nine Heavens unleash their lightning punishment, awakening the Mortal Extremity Divine Thunder: command thunder, wielding immense power! World-destroying stars fall, awakening the Mortal Extremity Tyrant Body: the mightiest physique, invincible in close combat! Heavenly light tempers the eyes, awakening the Mortal Extremity Pure Eyes: see through all things, down to the finest detail! Besides all that, Chu Fan has nine senior brothers and sisters, each with a Sacred Body bloodline and each a hegemon in their own domain! Chu Fan had wanted to be a carefree junior brother with an ordinary body, but his strength wouldn’t let him! The ordinary body is the strongest of all!
