Background and History

Xu Yi was a highly regarded mechanical engineer on Earth. At twenty-four, he fell into water during an engineering survey and awoke on the Sains Continent. He learned magic, entered Senkohaier Academy, and completed its course faster than usual, but graduated without Mages’ Guild certification or strong employment prospects. Stille secured him a position at Camilla’s Magic Tower after seeing the miniature, magic-powered piano he had built 1.

At the tower, Xu Yi combined mechanical design with Magic Arrays to develop a crystal-powered Magic Fan. Its commercial success led him to recruit student array-makers, lease land outside Bunta City, and establish a factory. The project also clarified his goal: to build an industrial system that uses magic to power machinery, rather than pursue magical rank as an end in itself 3 9 10 15.

Xu Yi expanded production with machine tools, dwarf craftspeople, and workers lent by Viscount Leslie. He developed a variable-speed fan and Magic Air Conditioner, partnered with the Fasak Merchant Guild to spread his manufacturing methods, and began work on a Magic Harvester. Materials, skilled labor, and production capacity remained persistent limits on his plans 18 23 30 32 36 37 42.

Appearance

Xu Yi is a young man with black hair. After washing the dust from his face during an encounter at the factory, Akali and Avita consider him handsome 7 40 41.

• Even features, expressive brows, clear eyes, and a straight nose 41.
• Long fingers and carefully trimmed nails 41.

Personality

Xu Yi favors demonstrable skill over credentials and practical uses of magic over status. He is willing to turn down profitable orders when he cannot guarantee consistent quality, and he funds research even when its return is not immediate 1 7 15 33.

He encourages collaborators with pay and recognition, but remains firm about safety and production standards. He also treats Vivian with care after rescuing her from a beating, while recognizing that earning her trust will take time 11 20 22 32.

Abilities and Skills

Magical engineering

Xu Yi’s principal skill is integrating mechanical systems with purpose-built Magic Arrays 1 8 42.

• Modified the Wind Spiral Array to give the Magic Fan controlled, steady power without damaging its blades or wasting crystal energy 8.
• Developed machinery for making screws and helped design production equipment for standardized fan components 18 32.
• Must adjust both mechanics and array output when available materials change a machine’s performance, as with the Magic Harvester’s bearings 42.

Magic

Xu Yi has talent for Magic Arrays and demonstrates Third-Level Mage ability, though he has not followed a conventional apprenticeship under Camilla 9 15.

• Can produce the third-tier wind spell Micro Tornado 15.
• His own magical ability limits which advanced arrays he can research without help 30 31.

Industrial organization

Xu Yi applies specialization, testing, and training to make production less dependent on individual experts 25 32 36.

• Divides fan assembly into simple tasks and teaches workers to operate machines safely 32.
• Rewards useful technical improvements and recruits researchers to develop arrays beyond what he can complete alone 21 22 42.
• Treats machine tools and manufacturing standards as more important to his long-term goal than fan sales alone 36 37.

Inventions and Projects

• Piano Model — a palm-sized, magic-powered mechanical piano built while he was at Senkohaier Academy 1.
• Magic Fan — his first successful household magic machine; later redesigned as a variable-speed model 3 12 34.
• Magic Heading and Thread-Rolling Machines — commissioned from Master Ranu to produce screws 18.
• Magic Air Conditioner — a crystal-powered cooling device developed for a wealthier market; Xu Yi also describes its ability to heat 25 37 47.
• Magic Harvester — an agricultural-machine project developed with the guild’s dwarf craftspeople and magic researchers 39 42 45.

Relationships

• Stille — supported his application to the Magic Tower, later helped with research and represented Xinfei in its advertising; the two share a teasing, trusting friendship 1 34 42 49.
• Great Mage Camilla — recognizes Xu Yi’s talent and offers to mentor him, but disapproves of his commercial path; Xu Yi continues to seek Camilla’s magical advice 9 31.
• Heinz — early business partner and later factory manager, responsible for day-to-day production and logistics 6 15 30.
• Viscount Leslie — landowner and investor whose stake rises to 30%; their agreement leaves Xu Yi in control of the guild 11 23.
• Vivian — a formerly enslaved girl Xu Yi rescued and brought into his household; he reassures her that he will not mistreat her 11 20.
• Master Ranu and Chief Shluka — dwarf contacts who help Xu Yi recruit craftspeople and pursue materials research 18 26.
• Akali and Avita — researchers Xu Yi recruits after assessing their approaches to difficult Magic Array problems 41 42.

Notable Quotes

“I’ve always thought magic was ultimately just a tool. Mages can use it to destroy things, so why can’t they use it to build things?” 15

“To stay in front, we have to keep innovating and adapting. That takes constant research.” 36
