After Twenty Years of Secret Cultivation, I Am the Human Race's Guardian!

January 1, 2782. Blue Star enters the era of the Four Great Catastrophes. Meteorites fall; ferocious beasts rampage from the planet’s core; solar flares trigger an ice age; and the lifting of Blue Star’s protective barrier unleashes an invasion by extraterrestrial species! … December 24, 2781. Li Mo died on the battlefield during the catastrophe caused by the extraterrestrial invasion. Reborn seven days before the Four Great Catastrophes began, he activates the Divine Choice System! “Catastrophe imminent. You have the following two choices.” “Choice One: Warn all of humanity and teach everyone the cultivation method you obtained from an ancient ruin in your previous life, leading humanity in preparing for the coming disaster. You will receive 100 million cultivation crystals!” “Choice Two: Hide in a training sanctuary and cultivate in secret. When the interstellar battlefield opens, charge forward without hesitation. You will receive the cultivation technique, the Eight-Nine Profound Art!” Warn all of humanity? As if! Only a fool would do something so thankless! Li Mo immediately chooses the second option, hiding away in the sanctuary granted by the System to cultivate in secret. Twenty years later, Blue Star’s protective barrier vanishes. An extraterrestrial race lands on the planet, seeking the opportunity hidden in the ancient ruins that have appeared as the interstellar war begins. Li Mo makes his move, swinging his sword across a hundred million miles and sweeping away every interstellar battleship!
