Tang Yue recalled reading about some rare spatial materials in ancient books, which would emit unique fluctuations under certain environments. Could there be such a treasure hidden in this sea?

Tang Yue knew all too well the allure of spatial materials to cultivators. If she could obtain a piece, it could not only be used to refine extremely precious spatial magic treasures, but might even help her further enhance her understanding of spatial laws.

Furthermore, they could also refine some spatial artifacts for the military, so they wouldn't be so passive when transporting classified information. Tang Yue herself didn't realize at this point that she already had a deep sense of belonging to the Chinese military.

Her heart raced, and her eyes revealed a hint of excitement and anticipation.

"Hehe, whatever it is, let's go down and find out." Tang Yue made the decision nonchalantly. Actually, she was quite confident. If she couldn't explore this sea area, she believed it would be even more difficult for others.

She carefully circulated her spiritual energy, wrapping herself up completely to guard against the dangers lurking in the sea. Then, she took a deep breath and plunged into the deep blue ocean.

She had to go down, and for some reason, her mental detection was greatly hindered in this sea area, as if something was blocking her way.

As Tang Yue descended into the water, she pondered the potential dangers of this mission. The pressure of the deep sea, the unknown marine life, and the special restrictions that might exist around the mysterious material—all were enormous challenges. These were things she had never experienced in the world of cultivation.

But these difficulties did not deter her; instead, they ignited an even greater fighting spirit within her. Challenges are everywhere.

"Now that I've started, I'm determined to find those materials, no matter what lies ahead," Tang Yue vowed silently in her heart.

Tang Yue searched through the space in her mind. When she was in the army, she had made some small things with some discarded materials. She wondered if they were useful.

She flipped through the items several times, but there were very few usable ones. Finally, her gaze settled on a small compass.

Tang Yue named this compass the "Spiritual Treasure Hunting Compass." It's actually similar to a compass, but she imbued it with spiritual energy. It can sense objects with abnormal fluctuations in spiritual energy, making it uniquely effective for finding rare materials.

However, those are Tang Yue's highest ideas at present, because there are limited materials and not much can be done now.

Tang Yue picked up the compass and infused it with a wisp of spiritual energy. The compass instantly emitted a faint glow, and the needle began to spin rapidly, pointing towards the deeper reaches of the sea. Seeing the compass's indication, Tang Yue was delighted; she hadn't expected it to actually work. Perhaps that was the direction she needed to go.
