Fang Yuan's visual acuity

Discord: Lostinrealityss Reddit: PerdidoNasRealidade Sovereign Immortal Fetus Gu Credit Bilibili: mc人祖 So, I'd like to go over a minor feat of Fang Yuan's that I still find pretty impressive. It has to do with the natural visual acuity of the Sovereign Immortal Fetus and what we can extrapolate from it through some calculations. The feat: In chapters 1022–1024, Fang Yuan tests the body of the Sovereign Immortal Fetus shortly after acquiring it. Without using any Gu or spending immortal essence, he finds he can clearly observe the landscape ten thousand steps away (approximately 8 km) and identify traces of an ancient battle on the ground. Even more notably, this exceptional vision remains functional while he runs at high speed through a dense forest, allowing him to avoid obstacles with ease. Angular resolution: Standard human 20/20 vision corresponds to roughly one arcminute. At 8 km, this allows distinguishing details of about 2.3 meters. Impact marks, cracks, footprints, and grooves are typically much smaller, requiring far higher acuity. Since the novel does not specify the exact size of the traces, the angular resolution needed for different detail sizes at 8 km is as follows: 10 cm| 0.043′| 20/0.86| 23.3× 20 cm| 0.086′| 20/1.72| 11.7× 30 cm| 0.129′| 20/2.58| 7.8× 50 cm| 0.215′| 20/4.30| 4.7× 1 m| 0.430′| 20/8.60| 2.3× 2 m| 0.859′| 20/17.2| 1.2× (Resolution in arcminutes, all values assume a viewing distance of 8 km) Using ~20 cm as a convenient and plausible …
