Ou Yangming suddenly realized that his body was suspended in mid-air.

His face revealed a trace of surprise. Flying with one's body was something that only Venerable Ones could do. Other than that, one could only use flying carpets, flying boats, and other special pieces of equipment, or ride on flying birds.

​​

Nonetheless, when Ou Yangming jumped into the strange hole, he did not land on his feet. Instead, he was suspended in mid-air.

The environment here was very different from the outside world. There was an indescribable buoyancy in the air that forcefully supported his body here.

Ou Yangming's eyebrows twitched slightly. He finally understood why the top-grade Spiritualists of the rogue cultivator clans were so eager to enter the Big Ruins. Perhaps they just wanted to experience the special feeling of flying with their bodies.

Especially for those Advanced Spiritualists who had the possibility of breaking through to become Venerable Ones, whether they had a similar experience or not was entirely different things.

Even so, unlike those Advanced Spiritualists, Ou Yangming did not deliberately experience this power.

His eyes were bright, and he was paying attention to this piece of void.

This place seemed to be an endless dark space but looking at it from afar, one could see that there were fixed giant holes in the distance. In those holes, there were hazy and alluring lights.

Apart from that, there were also meteors streaking across the sky in the darkness. These meteors had clear targets and were flying toward different holes.

Ou Yangming observed them for a moment and immediately understood that those caves should be the gateway to the Big Ruins and Zhangzhou. Judging from the aura coming from each cave, he could clearly tell where the other side was.

Whether it was entering the Big Ruins or returning to the Spiritual Realm, there were many different entrances. This was much more convenient.

Ou Yangming's eyes moved. He knew there was a limit to the time he could spend here, so he could not stay here for a long time. After identifying a certain direction, he quickly flew away.

Although he was flying in the air, the feeling he felt at this moment was almost the same as swimming in water. If there was any difference, it was that he could breathe freely here without the danger of suffocation.

The hole he had identified was the nearest entrance to the Big Ruins. The aura coming from the inside was extremely dangerous, so much so that he felt a sense of trepidation. Nevertheless, it was precisely because of this that his heart was filled with anticipation.

Even though the pseudo-flight was not fast, he moved steadily in one direction.

Moreover, Ou Yangming also discovered that the speed of all the lights in this space was almost the same. There seemed to be some mysterious and powerful force that perfectly controlled this place.

All of a sudden, Ou Yangming, who was flying, was slightly startled. Not only did he not increase his speed, but he actually slowed down because he saw a familiar white light.

He pondered for a moment and suddenly released his spiritual power. Next, his face revealed a hint of surprise. This was because he had confirmed that the source of that light was the same as what he found in the magma at the volcano.

In this dark void, it was not exactly empty as a large amount of Volcanic Ores were embedded into this place.

Ou Yangming was not shocked but happy. He did not have much knowledge about Volcanic Ores. He had some insights, but how could they be compared to the experience of countless mighty figures in Zhangzhou over the past tens of millions of years?

Therefore, at this moment, when he saw the opportunity to see the secrets within, he could not help but feel overjoyed.

He controlled his body and let go of his mental conception to explore carefully.

There was no one else around, but Ou Yangming knew they were inside a massive formation. Inside this formation, there was an incomparable sturdiness. It was definitely not something he could destroy.

Of course, Ou Yangming also believed that apart from sturdiness, the probing ability was also essential in the formation. If he released his spiritual power without any restraints, he would surely be noticed by the people guarding the formation map. Therefore, when he moved, he also curbed his curiosity and only carried out a small-scale search without alerting anyone.

Nothing could be seen in the void but waves of invisible power were omnipresent.

Ou Yangming silently sensed it, and a look of surprise gradually appeared on his face.

A node.

In this spot where the white light was flickering, it was actually an interspatial node.

With this node as the center, the magical energy expanded in the form of a spiderweb and finally condensed into a big network.

Ou Yangming's mind moved slightly. His body was still moving, but he had quietly changed his direction a little. He followed this network and slowly flew toward another place. During this process, he kept paying attention to the changes around him and the special energy flow in the space.

At the spur of the moment, his eyelids twitched because he found another node.

Despite that, this node was insignificant compared to the previous one.

After carefully identifying it, Ou Yangming was sure that what was embedded in this node was also a Volcanic Ore. Having said that, it was not a white Volcanic Ore, but a green one, which was of the lowest grade.

His body paused for a moment before he continued moving forward. With the experience of 2 discoveries, he became more familiar with this energy. Soon, he found more green Volcanic Ores.

These Volcanic Ores were distributed evenly as if they were drawn with a ruler without any deviation.

Up until now, these Volcanic Ores and the energy connection between them gave Ou Yangming a feeling that they were as steady as a mountain. He knew that outside the formation, there was a powerful interspatial disturbance that could destroy everything, but he could not feel the slightest bit of fear.

Without warning, Ou Yangming paused again because he discovered a yellow Volcanic Ore.

Ou Yangming's eyes lit up slightly, and a huge topographic map was drawn in his mind. It was still a void space but in his eyes, the space was already filled with numerous Volcanic Ores and an indescribable amount of energy.

As if to verify the picture in his mind, Ou Yangming suddenly sped up. Just as he was approaching a certain void space, his body stopped, and he muttered, "Green."

Sure enough, on this tiny node, there was a faint green light.

His body continued to move forward. After passing through several nodes, he softly uttered, "Yellow."

Following that, he felt a familiar energy and a faint luster.

In fact, these so-called luster and energy were so faint that they were almost non-existent. Even Ou Yangming might not be able to notice them unintentionally. However, with the white Volcanic Ore as the node and when he explored along with the energy, there was no place for them to hide.

Ou Yangming' became more excited. He vaguely felt that he had found the specific network of this magnificent formation.

He continued to follow the pattern and not far ahead, he finally found a ray of light that he had been looking forward to for a long time.

It was another white Volcanic Ore!

Ou Yangming calmed himself down and quietly sensed the flow of energy in the void. Gradually, he found more things.

Inside the infinite void, there were many nodes.

These nodes were the most crucial parts of the formation map.

Of course, on each node, there was a different importance. Those important nodes were obviously given special care. Each node had a white Volcanic Ore and as the nodes expanded, the secondary nodes had yellow Volcanic Ores.

As for the most common nodes, they naturally had the lowest level of green Volcanic Ores.

These nodes, as well as various Volcanic Ores, expanded bit by bit. They gathered all the energy together indescribably to form an unbreakable defense network.

Ou Yangming's eyes flashed, and his gaze unknowingly looked toward the distant unknown location in the void.

When he discovered the second white Volcanic Ore, he also discovered more things. According to the flow of energy, there should be a more important core node above those white Volcanic Ores.

Then, what quality would the Volcanic Ore that was placed on the core node be?

The legendary red Volcanic Ore...

Once this thought surfaced, Ou Yangming could not help but think about it.

After hesitating for a moment, Ou Yangming turned around and slowly flew toward the place where energies were continuously gathering.

The entrance to the Big Ruins was right in front of him and would close if he delayed any time. That said, the chance to see the red Volcanic Ore was even harder to come by. Moreover, the young fellow had a feeling that if he were to find the core node and use it as a reference, his attainments in formations would definitely advance greatly.

This was an incredibly rare opportunity.

Even if there was only a one in a thousand chance, he would not easily miss it.

However, just as he turned around and advanced for a moment, a voice filled with majesty sounded in the void.

"The passage's entrance is about to close. All of you must quickly pass through or your lives won't be cared for anymore!"

Ou Yangming paused, and the corner of his mouth twitched. Only then did he gather his thoughts and look around.

There were still a few rays of light that were like meteors in the void, but they became very few. There would not be more than 10 of them.

It was clear that other than them, the others had either entered the Big Ruins or returned to the Spiritual Realm. They were the only ones stuck here for various reasons.

Ou Yangming looked into the distance, his eyes filled with regret. Subsequently, he turned around and rushed into one of the entrances to the Big Ruins at an even faster speed.

Darkness suddenly fell behind him, and the endless passage closed.
