Here are the ideas for what Tech Shi can do, in Wuxia Space Opera (kung fu myth in space). A Tech Shi is a scholar of those 'chi arts' that pertain to technology and machinery, including the Heavenfield. This is the intergalactic computer network/matrix governed by ancestral AI known as Hsien. It is largely dominated by the Cultured Worlds, the setting's oppressive and isolationist empire that has the most power.
The purpose for posting these ideas is to find out whether they seem viable, in keeping with kung fu space opera (imagine the Clone Wars drawn by Tony Wong). I have tinkered with many ideas on how to mix chi with technology, but I don't want something too esoteric, or too plain. Each 'ability' or field of Tech Shi expertise is paragraphed separately, enjoy:

Yin Yang Mechanics is a Chi art that allows the practitioner to enhance or reduce the functionality of equipment through application of the principles of opposites – yin and yang. With the expenditure of Chi and the application of prepared equipment, the practitioner can apply the desired level of functionality into an item.
To enhance the functionality, the practitioner must apply prepared equipment that is the same according to whether it is yin or yang in nature. In order to reduce its functionality, the opposite must be applied.
This is a process that requires time; it cannot be done instantly, or in the heat of the moment. Yin Yang Mechanics is also the process by which equipment is repaired in a way more effective than conventional engineering.

Tech  Alchemy refers to the practise of gathering unique ingredients that, when catalysed with the practitioner’s Chi, serve as power sources and fuels. Machine Alchemy also creates the fuels used to prepare equipment for Yin Yang Mechanics, as well as for preparing the Gears of Change.

A Wubox is a sentient computer built by the practitioner and powered by Chi; they accompany the practitioner serving as portable computer systems. However the technology dates back to the early Tech Shi and is more than a mere floating computer node. Wuboxes are fragments of Wuji – hyperspace – contained within computer cores and bound by the sacred Trigram Codes of the Tech Shi. This allows them to store not only vast amounts, entire universes, of data (such as entities exorcised from the Heavenfield, which some believe is nothing more than a giant Wubox), but actual physical material – such as the tools used in (and the prepared materials for) Yin Yang Mechanics. With the application of inner power, the practitioner, to whom the Wubox is coded, can place items in and pull them from his Wubox.

Machine Spirits are computer entities other than the powerful Hsien that govern the digital domain of the Heavenfield. They are usually known as Ghosts and can be ancient and powerful; in some cases ruling nodes that dominate worlds within the outlying Celestial Margins. They can also include the digitised personas of those that have transgressed against the Cultured Worlds, sentenced to serve the Hsien as slaves, their programs altered to make them pliant. Tech Shi Chi arts, through knowledge of the ancient Trigram Codes, and their Wuboxes, can deal with Machine Spirits; though Hsien are by their nature too powerful to control in this way.
Tech Shi can compel Ghosts from machines into suitable vessels, including Wuboxes (where they remain imprisoned and ultimately can still communicate with their jailor, often pleading clemency in return for help). The Trigram Codes are the building blocks of the Heavenfield and all computer information as well as the systems that manage them. Only Tech Shi understand (and guard) these codes and have the power to use them. Thus Tech Shi are called upon to deal with errant, fickle, and impossibly ancient Machine Spirits. In the Celestial Margins, the Heavenfield is often fragmented, separated from the core that remains at the heart of the isolationist Cultured Worlds.

The Gears of Change are created from salvage – broken and useless equipment (the older the better) – and prepared by Tech Alchemy to create a powerful divinatory tool. When cast, usually across a symbol of the Wuji, hyperspace, the Gears create a pattern that can be understood by the practitioner through application of Chi in order to divine the best course of action in a specific area. The practitioner will receive advice that is not easy to understand, but the efficacy of which can be increased depending on the nature of the salvage used to create the Gears. If that salvage comes from something used in the area in question (such as weaponry used to create Gears cast to determine how to proceed with a fight), it will provide a better result. Once cast the Gears must be destroyed: it is extremely bad luck to cast the same Gears more than once. Who knows what disaster may befall the practitioner that tempts fate thus.
