The reason Su Yang was suspicious of this little creature was mainly because it was also of unknown origin.
It came out from the chaos, truly from within the chaos. Just being able to survive in the chaos, even if it's just a worm, shouldn't be underestimated.
In the Land of Chaos, many Saint Emperors, even Great Saint Emperors, were devoured and killed by the meat worms within the chaos, right?
This little bird can take on many chaos meat worms by itself, indicating that its strength is quite formidable too.
Moreover, when the meat worm entered the Land of Chaos, Su Yang did see the situation. It used some unknown method to make an opening in the space barrier of the Land of Chaos and then slipped inside. However, this opening would slowly recover in a short time, returning to the original state of the space barrier, making it impossible for outsiders to notice any previous fissure.
