Sword Immortal, Starting from Hex Strengthening

He Junan traveled through the world of immortality and became the most useless disciple of the Five Elements Spiritual Roots in Shushan. After eight years of hard training, he was still in the early stages of Qi training. Until the [Hex Strengthening System] is activated, choose [Open Swing] at the beginning - if you don't practice for three years, you will break through two realms at the end of the period! When everyone was shocked, He Junan looked at the new choices in the system and smiled. [Featherweight] makes his basic swordsmanship as fast as lightning; [Chaos Summons] unexpectedly summoned what seemed to be the legendary immortal-killing flying knife! Then during the outer sect competition, he shouted "Sword!" And summoned the founder's Zongzong Divine Sword! Then inject the steel of the heart into the natal spiritual sword. The greater the ability, the bigger the sword will be! A few years later, He Junan stood on the top of a mountain in the mortal world, took off the gourd from his waist, drank deeply, and then offered a huge sword that covered the sky—— "Little Tianmen, open!"
