Top-Notch Spirit Stones

Before Yu Su could touch it, she could already feel the fluctuation of energy. She had not noticed it previously, so it was probably blocked by the box.

This box was also meticulously made.

Top-notch spirit stones could only be chanced upon by luck. One could increase a lot of magic power.

On the other hand, Yu Su's bottleneck had long loosened. It was precisely the supply of energy that she lacked. These three spirit stones would help a lot.

With these three spirit stones, she could advance to the realm of Great Fulfilment.

The spirit stones came at the right time.

Yu Su used the spiritual artifact beside her to set up a defensive array. As long as someone entered the room, she would be able to sense it.

Then, she sent a message to people that were close to her, telling them that she would be in seclusion for a few days.

Then, Yu Su entered the room and began to cultivate.
