In a quiet valley, everything is as usual.

The fluctuations actually came from the waterhole below, and the divine sense probed into the depths of the waterhole, and suddenly found an incredible scene.

At the bottom of the deep pool, there is actually a space, which is covered by a huge bowl that seems to be dozens of zhang in circumference, the giant bowl is transparent, and occasionally it is very rhythmic and flashes of colorful glow.

Now, it was as if a big hole had been cracked on the huge bowl, more than three feet wide and more than a foot long.

Strangely, there seems to be another film on top of this gap, which prevents the water from flowing into the pool, but the light can shine through.

The divine sense probed into the inside of the large array below, and after all, it was affected a little, and the detection was not clear, but it was only roughly known that the internal space was extremely large, and it seemed that there was a vine plant growing there.

"Do you mean ......?"

Shen Yun's eyes lit up, and he looked up at the sky, and it was about time at this time.

The giant bowl was obviously composed of formations, and Shen Yun knew that no matter whether it was a formation, an enchantment, or a prohibition, once it was arranged for a long enough time, it would automatically form a formation cycle.

This cycle is usually timed in years, once the time period of the formation cycle is reached, the formation will expose its own flaws, it may be a small gap, or a big crack, or even the entire formation will be completely invalid for a period of time.

The length of time for the flaw cycle, and the length of time for the flaw to be revealed, depends entirely on the power and perfection of the formation itself.

Therefore, for a long time, many ancient cave mansions were not known, but by chance, they would be discovered by monks inexplicably, which is the reason.

Could it be that there is an ancient Xiudong Mansion below?

Shen Yun's eyes were burning, and his heart was hot. The Ancient Cultivation Cave Mansion usually has a lot of collections, and if you can harvest all the mantles of an Ancient Cultivator, it will naturally be of great help to your cultivation.

At this time, the Great Array is still slowly repairing the cracks, and once it is completed, the formation will be restored to the same as before, until the next cycle cycle, and the cycle will start again.

"No wonder there's no aura in the valley. Shen Yun nodded slightly, this place was obviously the same as the original Xiaosong Mountain.

Taking a deep breath, my heart was worried, and the crisis of the Komatsuyama Ancient Tomb was still fresh in my memory.

If this is really an ancient cave mansion, then the danger is self-evident.

Investigate again, the only thing that is certain is the transparent shield covering the cracks, it should be an independent formation or prohibition, and the effect is waterproof, so the large array is exposed, and there will be no water in the cave.

This formation was so huge that even the entire valley was shrouded in this large formation.

With such a large array, the power is amazing, and it is impossible to break the passage with a broken formation. So if you can't find the core and break the big array, I'm afraid that you will eventually be trapped and unable to come out.

"It seems that we can only do a brief probe before the crack is repaired. ”

"Except for a spirit vine below, there don't seem to be any other creatures, so I don't think there will be much danger. ”

Shen Yun groaned slightly, look at this valley, I don't know how many years no one has set foot on it, it is estimated that there are unlikely to be demon beasts or monks in the large array below.

Time is of the essence and there is no need to think it through.

Having made up his mind, Shen Yun no longer hesitated, only to see a flash of red light on his body, and the spiritual power shield was revealed.

"Poof" and jumped into the deep pool.

Diving into the crack like a fish, it easily passed through the membrane and jumped into the ancient Xiudong Mansion.

The peculiar thing is that when he passed through the film just now, the film was attached to Shen Yun, and when he passed through it entirely, it automatically fused, without even bringing a single water stain.
