Zhu Yunfei traveled through time and came to the world of comprehension where demons and ghosts are rampant, and became an ordinary inner disciple of Qingtian Sword Sect. Because he molested the sect's saint, he was imprisoned in the back mountain to think about the cliff and face the wall. Zhu Yunfei awakened to the god level Sign-in system. Sign-in on the first day of Siguo Cliff: get the supreme sword heart, ten thousand swords return to the sect. Sign-in on the tenth day: get the sword-cutting technique. One hundred years later, demons ravaged the Qingtian Sword Sect, and the sect was in danger. Zhu Yunfei signed in for a hundred years, cultivated the supreme swordsmanship, and walked out of the cliff of self-thinking. Just when all beings were in despair, a sword flew from outside the sky, and the world Depressed by it.
