Lu Ming suddenly thought of the tide.

Could the tide have something to do with this?

Could this be the source of the tide?

He did not know, he had no way to know. The dean had rushed here at an extremely fast speed, but he discovered that the cave had disappeared, and the place had completely collapsed. The dean's face was filled with regret.

"This is bad!"

He quickly waved his hand and a formation that took up almost the entire sky appeared. The dean waved his hand and the formation suddenly shrank, turning into countless streams of light and sliding in all directions.

"Hopefully, I will be able to make it in time."

Facing this place, the dean gently stepped on the golden light with his right foot, sending it flying in all directions like a snake. He then quickly surrounded this place and sealed it.

Lu Ming slowly walked forward alone. Just as he killed two skeletons, these two guys actually wanted to attack him.

However, these skeletons did not seem to have much strength. Their entire bodies were ashen white, as if they would fall apart with a single blow.

He couldn't help but be surprised. Was this really the Underworld?

He didn't know.

Lu Ming did not dare reveal anything, and even more so, did not dare to remove the barrier outside.

It was because he noticed that there was something special around him, and it was because he sensed an aura faintly eroding the spiritual energy within his body.

Lu Ming knew that the Spirit Qi in his body could only be used up in this world and could never be replenished. Fortunately, he brought a lot of Spirit Stones with him during his holiday.

Furthermore, the majority of the stones inside were of a higher grade and could help Lu Ming deal with his current situation. However, he was not anxious at all as he slowly wandered around the world by himself.

There were Skeleton Horses, humanoid skeletons, and some carrion birds.

There are unspeakable creatures in the swamp who can reach out, or reach out with their claws, to grab anything that passes by.

Just then, Lu Ming saw a skeleton being grabbed in, its bones all turned into dust.

From a distance, Lu Ming saw an existence of land. He increased his speed and flew over, gently landing on it, then discovered that some of the grayish-white grass had already grown under his feet. Lu Ming did not know if the grass was alive or dead, but the surrounding trees had already completely dried up.

Suddenly, Lu Ming felt his hair stand up, he immediately dodged to the side, a skeleton appeared, the skeleton hand actually held a blade and fiercely slashed at Lu Ming, although he was not strong enough to injure it, but was still shocked.

Lu Ming looked at it carefully. This skeleton seemed to be a little different from the others.

This skeleton emitted a metallic color, and the axe in its hand looked like it was made of bronze. The flames of a soul danced in its two eyes.

Lu Ming only extended his finger gently and the entire skeleton turned into smoke, this kind of skeleton was nothing in his eyes.

There was a hidden danger within the forest, and many creatures attacked Lu Ming. However, Lu Ming was not worried about dissolving all of them, and very quickly, he reached the deepest part of the forest.

Just then, Lu Ming suddenly saw a gigantic town on the horizon in the distance.

Above the town, another black shadow flew by.

There were actually towns here. What kind of place was this? If Lu Ming wanted to find the answer, he was afraid that he would have to go there.

However, Lu Ming did not dare, because it was too strange and dangerous inside. If he really went there, he would be killed by an existence stronger than him and he would not even have the heart to cry.

Lu Ming could only stop at the top of the mountain for the time being. He randomly picked a place to carve out a cave, completely sealing the cave entrance and carefully observed his surroundings from inside by himself.

After observing his surroundings for a few days, Lu Ming finally had an understanding of his surroundings.

This should be the Netherworld.

It was the place where they arrived after they died.

But they would forget their memories from the Immortal Cultivation World.

When all the living creatures had just arrived in the underworld, their bones were all gray, and they weren't very strong. They could increase their strength by killing their own kind and absorbing their soul flame, which would then change into a shiny bronze color.

The strongest skeleton Lu Ming had seen was a Silver Skeleton.

The levels that he had observed so far were mainly Grey Bronze, Iron, Copper and Silver. According to Lu Ming's guess, there should still be gold and diamonds on top of them.

Moreover, at every level, their colors would change from the weakest at the beginning to the pure strength at the end. However, the higher their level was, the less likely they would fight each other. Every time they would meet him, because at that time, they would already have a certain level of intelligence and wouldn't easily attack.

Lu Ming's current strength should be between silver and gold.

He should be able to deal with seven or eight Silver grade monsters attacking him. However, if there was only one Gold grade monster, then it would be difficult for him to deal with it. However, no matter what, there didn't seem to be any Gold grade monsters around him.

Lu Ming held his own treasure sword and slowly floated in this world. He had just cleared all the corrupt organisms in the area, and there were basically no living beings within five kilometers of him.

However, what Lu Ming did not know was that his actions very quickly attracted the attention of the surrounding golden skeletons.

The Golden Skeleton's intelligence had already reached the level of an ordinary human.

It even exceeded that of ordinary humans. Just now, his subordinates had reported that in a certain area, a mysterious existence had suddenly appeared and killed quite a few other skeletons.

The appearance of this kind of thing usually meant two things. The first was that an expert from a first-rate race had appeared and was clearing away everything in the surroundings. The second was that an exception had appeared in their Skeleton Organization.

This unconventional method of increasing his strength at a rapid rate could very well threaten his position, because not all skeletons could turn into gold. Just like humans, this sort of thing was also focused on talent and luck.

The golden skeleton pulled out a blade from beneath his seat. No one knew where it came from.

Only he knew that this blade was made from his own ribs. It was extremely sharp and extremely tough.

Bringing his seventeen silver skeletons and his vast army, he approached Lu Ming.
