Am I a Sword Saint?

[Drama Flow], [Happiness and Relaxation], [Positive Energy] Reborn in an era when the Seven Kingdoms were competing for hegemony, Confucianism and Taoism were at their peak, and demons and evil were rising. Li Qingtian studied under Taoist Cao Jin of Shangjin Temple and learned the Taoist's unique skill - Deyun's Four-Character Technique. As a young Taoist priest who only knew the Deyun Sect's outer sect's introductory techniques, Li Qingtian knew that his skills were too low to be useful, so he practiced at Shangjin Temple for three years, only looking forward to being able to go out and see the world one day. Once the little Taoist priest came out of the mountain, he discovered that the world outside was really wonderful! But the world outside is very helpless... Why is this little Taoist's sword so powerful! How come his Deyun Four-Character Technique is different from the legendary one!
