I Am One Month Away from the College Entrance Examination and Got the System!

[The protagonist is invincible + there is no heroine + no pressure on strength] "Ding! Congratulations to the host for signing in to the innate Taoist body today!" "Ah?" A graduated college student named Zhao Xuan suddenly died in a rental house one night and traveled to a world called Canglan Star. Here there are far more advanced technologies than in previous lives, warriors who only appear in online novels, and monsters that have been fighting against humans since ancient times. Moving mountains and filling seas, catching the stars and the moon are just a snap of the fingers for the martial arts giant. Fortunately, Zhao Xuan has awakened and activated the sign-in system. As long as you sign in every day, you can get various rewards! Sign in and get all the treasures such as the innate Taoist body, the nine-transformation divine art, and the weapon embryos! Let's see how Zhao Xuan used the awakened sign-in system to reach the top of martial arts and defeat the alien race! Realm: Martial Apprentice, Martial Artist, Martial Master, Great Martial Master, Martial Sect, Martial King, Martial Emperor, Martial Saint, Martial Emperor, Martial God!
