Zhou Wen carefully recalled Origin Realm King's two battles and specially watched a few important parts of the recording. The things that he originally felt were amiss gradually became clearer.
If I view Origin Realm King as a Companion Beast similar to Primordial Spore, or something even smaller than Primordial Spore, so small that even the Holy Hell King's eyes can't see the sinflames on its body, wouldn't that explain why Primordial Sword Immortal's sword beam can't hit it? It's not because its speed is so fast that Primordial Sword Immortal can't hit it, but because it's too small. In that case, its strength definitely can't be too strong. Therefore, although it looked like it was thrashing Primordial Sword Immortal in all sorts of ways, it was actually unable to kill Primordial Sword Immortal due to its insufficient strength.
