Actually, the best way to deal with the Fox Spirit is to envelop the entire house in Golden Light, but upon thinking about it, it seems impractical. If the four walls are fortified with Golden Light, where would the Fox Spirit enter from? It would only be able to burrow in from underground. However, if Zhang Chen wants to trap the Fox Spirit, he must fortify the ground with Golden Light after the Fox Spirit burrows in, but the Fox Spirit is no fool; upon realizing something's amiss, it might just directly perform an Earth Escape and leave. Once its feet touch the ground, its Earth Escape speed is undoubtedly faster than the speed at which he can fortify the ground with Golden Light.
