Lower tech option for the HUD to highlight pressure points, for precisely targeting strikes: goggles.
What are some other ways to apply technology to Chinese medicine, wuxia magic, and so forth? Or other synergies?
How do we implement the Ringwraiths? I guess that might depend on the nature of the Ring-analogue. They might not actually be bonded with the Central McGuffin, but they should at least be minions of its creator. If the One Thing is the control chip for the Orbital Mind Control Laser satellite system, then maybe they're early test subjects of the mind control device, thus their fanatical loyalty. What about their mounts - are they still animals, that is, horses and then pterosaurs? or motorcycles and then flying motorcycles?
The Ring Wraiths could be cultivaters with fire deviation. Or they could have cybernetic implants that block some acupoints and empower others to an extreme degree. Maybe tech somehow opens up the world of ghosts and spirits? You could bring in some Chinese Ghost story stuff for that.
