A Seraphim

The Sandworms made them feel powerless. The body of these creatures could even withstand the dragon's breath!

The Sandworms could also devour rocks and boulders and spew gravel to recover from their injuries.

Even when they injured the creatures, the Sandworms dived and reappeared within a few minutes, fully healed.

The Sandworms' aura of rage was palpable. Only when the aura subsided did Su Wan finally relax. The most difficult moment had passed. 

Su Wan had used all her trump cards and they were finally safe!

Her greatest trump card had yet to appear. Xu Yuan wasn't here yet.

She had learned something from this incident, too. She would no longer be lazy and arrogant. She vowed to upgrade her territory as soon as possible and train every day to become stronger.

Su Wan was happy that she had done well this time, but she couldn't be arrogant. She had much to learn. Her territory was still not as powerful as she wanted it to be.
