Ten Thousand Miles of Blue Clouds (萬里靑雲)
: Like blue clouds stretching across ten thousand miles, a swordsman who advances towards the endless realm of the Dao.

[Basic Information]
Name: Mook Sowoon (墨少雲)

Affiliation: Third-generation direct disciple of the Tian Shan Sword Sect.

Weapon: Hanwol Sword (寒月劍) - A spiritual sword forged from ten thousand years of cold iron, imbued with blue sword energy.

Personality: Possesses an intellect as cold and serene as eternal snow, but reveals a fiery righteousness when wielding his sword. He is the epitome of a traditional swordsman who proves himself through his blade rather than unnecessary words.

[Worldview and Growth Narrative]
1. Descendant of a Fallen Renowned Family: He was originally the second son of the Mook family (墨家), one of the most prestigious families in the Central Plains. However, his family was annihilated in a surprise attack by the Demonic Cult. He survived alone, gained a fortuitous encounter in the Tian Shan mountains, and entered the Tian Shan Sword Sect. However, due to damaged Qi and blood, he received the despairing prognosis that he could 'never practice martial arts again'.

2. Ordeal on the Mountain Peak: Sowoon did not give up. In the quiet of the night, he began a grueling ascetic practice on the summit of a snow-capped mountain thousands of meters above sea level, enduring storms and painstakingly reconstructing his Qi and blood. The image depicts him just before descending the mountain, having finally comprehended the ultimate techniques of the 'Twelve Swords of Tian Shan' (天山十二劍) after ten years of seclusion.

3. A New History Written with the Sword: Now, he pursues the 'Dao' not merely for family revenge, but to rectify the corrupted order of the martial world. The world seen from the cloud-covered peaks appears small and ephemeral, but he has realized that protecting the lives within it is the true path of the sword.

[Martial Arts Characteristics]
Mind Cultivation: Bingso Simgyeol (氷消心訣): A secret technique of the Tian Shan Sword Sect that manipulates extremely cold True Qi to freeze the opponent's internal energy flow.

Ultimate Technique: Cheongun Manri Geom (靑雲萬里劍): A sword style where blue sword energy surges like clouds, overwhelming the enemy. It is as unrestrained and magnificent as the spirit of the high mountains where he stands in the image.
