Ma Yuan later shared what had transpired, which earned the Starlight crab another beating from Yang Qing, which left it feeling very greaved that it made a few inscrutable noises which Yang Qing loosely interpreted as it saying it would never come out of the pond again, if that was the treatment it was getting for doing its job.
To prevent any future trouble because Yang Qing didn't quite trust Starlight, he employed a few measures to keep Ma Yuan safe. One was to ask the two black dragon horses to keep an eye on Ma Yuan when he was around. With their presence, the starlight crab could forget about acting up. Ideally, he would have asked the Celestial nesting weaver, but it was too lazy and arrogant to agree. It would likely mock Yang Qing if he dared ask.
