The sword technique that Li Hanyi practiced was the Still Water Sword Technique.

The Han sword had a slender body, a wide hilt, and a sharp blade. It was suitable for assassination and could be used to attack in various ways. The swordsmanship could be divided into three categories: the fighting swordsmanship used for fighting or performance, the performing swordsmanship used for the connection and transition of swordsmanship routine movements, and the swordsmanship that was similar to the shape of a sword, which was a variation of the fighting swordsmanship and the performing swordsmanship. Moreover, each type of swordsmanship contained a variety of swordsmanship with different movement characteristics and purposes.(For example, offensive sword style, defensive sword style, rigid sword style, elastic sword style, etc.). Based on the characteristics of the Han sword itself, it was suitable for sword styles that matched the characteristics of the sword body. For example, offensive sword styles that emphasized assassination and chopping movements might be more suitable for the Han sword. However, the specific suitable sword style would also vary according to the user's purpose (such as actual combat, performance, etc.).
The sword technique that Li Hanyi practiced was the Still Water Sword Technique. This sword technique was taught to her by Li Changsheng. After cultivating it to the extreme, she could enter the Soul Travel Realm with a single sword. However, although Li Hanyi had outstanding talent and cultivation speed, she had never comprehended the essence of the Still Water Sword Technique and could not reach the highest realm of the sword technique. She had once tried to enter the still water with heartlessness, but was always disturbed by affection. In the end, she changed to practicing the Affection Sword and entered the Half-Step Immortal Ascension Boundary. Even so, her swordsmanship was still not as good as the other five sword immortals. However, after meeting Zhao Yu, her swordsmanship had a new understanding and breakthrough. All in all, Li Han Yi's swordsmanship had an important position and development in 'Song of the Youths'.
Li Han Yi's swords were Iron Horse Ice River and Listening to Rain. The Iron Horse Ice River was the coldest sword in the world, ranked fifth among the famous swords. The Rain-listening Sword was once held by Li Hanyi. When she went to Wangcheng Mountain to ask Zhao Yu about the sword, she had used both swords. Later, Li Hanyi gave the Rain-listening Sword to her brother, Lei Wujie, and the Rain-listening Sword became Lei Wujie's sword.
Li Hanyi's sword techniques included the Water-sealing Sword Technique, Moonlight Sunset, and Thunder on the Ground. Li Changsheng had taught Li Hanyi the Still Water Sword Technique. When this sword technique was practiced to the extreme, it could allow one to enter the Mental Wander State with one sword. Originally, one needed to be calm and emotionless, but after Zhao Yu died, she had a new understanding of the sword technique and entered the Half-Step Mental Wander State. In " The Young White Horse Drunken in the West Wind," she had also created the " Amorous " sword technique, which combined her deep affection for Zhao Yu and her unique understanding of swordsmanship. This sword technique had once broken the Killer God's Single Blade, and it was said to have reached the Mental Wander State. She had also created a set of swordsmanship called " Red Mist and Green Dew ", which had the beauty of being crystal clear like dewdrops and the vitality of red mist and green willows.

She had once forced back the eight elders of the Demonic Sect with a single sword, displaying her formidable strength. Her talent in swordsmanship was outstanding, and she had already entered the later stage of the Free and Unfettered Heavenly Realm. However, in a battle of the same realm, her lethality was slightly lacking. In the battle against the three elders of the Tang Sect, she had almost no room to retaliate. Her performance was barely satisfactory. As a result, her sword immortal strength could not be ranked in the top three. However, she had a brave boyfriend, Zhao Yuzhen, who had saved her at the critical moment. In summary, Li Han Yi's sword immortal strength was considered to be below average in the " Song of the Youth ".
