The seventh-rank fire wyrm's Primordial Spirit essence was simply too ferocious. After struggling only a few times, it tore the net apart. Fortunately, Lu Xiaotian had already been prepared for the fire wyrm's strength. The instant that gray net broke, another gray net enveloped the fire wyrm.
The price of completely imprisoning this seventh-rank fire wyrm's Primordial Spirit was unprecedented. Before long, the second gray net also showed signs of breaking. Lu Xiaotian's expression changed. With his main Primordial Spirit alone, he feared he would be unable to do anything to this seventh-rank fire wyrm essence spirit.
Lu Xiaotian made a prompt decision, ordering his second and third Primordial Spirits to stop deducing the formation.

It even tried several times to flee outside, only to be forced back by the formation Lu Xiaotian had arranged in advance. The fire wyrm's Primordial Spirit was exceptionally fierce; several of its charges even loosened the formation's restrictions considerably.
