A carp (alkyne) swimming up a waterfall falling from a legendary mountain (energy gap that is hard to jump without photoexcitation) accepts a pearl (alkyl radical) prepared by an oyster (Ir photoredox catalyst) under sunlight irradiation and becomes a dragon with a pearl in its mouth (Markovnikov‐type product) or in its claws ( anti ‐Markovnikov‐type product) after going through different longmen or dragon gates (different Ni catalysts). The comparison is based on a myth popular in East Asian countries. More information can be found in the Research Article by Y. Nishibayashi and co‐workers (DOI: 10.1002/chem.202200727).
