God of Martial Combat: Starting by Climbing the Tower of Transcendence

The mysterious Tower of Transcendence appears in Qi Ji's dreams, bringing him countless formidable foes. He slays a cherry-blossom ronin and masters the secret art of the Tennen Rishin-ryu: the Three-Stage Thrust of the Sword of Emptiness. He defeats a Sith swordsman and grasps the supreme principle of Meyer swordsmanship: the Master's Strike. He overcomes a Daxia blade master and learns the Zhenwu secret technique, the Meridians-Nourishing Method. The Hiten Mitsurugi-ryu, the One-Form Demon Blade, the Nameless Divine Wind Style, the Three Blades of the Avici Path, the Heavenly Blade... As Qi Ji displays more and more wondrous blade techniques in all kinds of settings, everyone is at a loss. Are those moves of yours even legal? In brief: The protagonist learns all kinds of fantastical moves through the Tower of Transcendence, then duels sword masters around the world in real life, gradually climbing to the top. (Volume One is grounded in reality; Volume Two takes place in another world. After gaining extraordinary powers, he settles permanently in that other world.)
