829 I Am the Old Principal's Tamed Beast!

Not knowing that Dong Xin had already discovered the secret regarding the Byzantium Helios Beast, Zhang Xuan was currently making his way over to the Formation Master School.

Even though he had set up his Aura Sealing Formation impeccably, the formation's grade was ultimately still too low.

While the Byzantium Helios Beast was tightly squeezed inside the Myriad Anthive Nest, it was still a saint beast with incredible regenerative capability. In just a few days, it had mostly recovered from the wounds it had sustained previously.

Thus, as soon as it was released in the courtyard, it exerted its full might to break the formation so as to escape.

It was fortunate that Zhang Xuan had expected such a situation and had prepared in advance for it. Through utilizing the strength of Vicious and the Otherworldly Demon puppets, he had managed to subdue it eventually.

However, that wasn't a feasible solution in the long-run.
