Chapter 426: Netherworld Mine, Frozen Ancient Beast

Netherworld Mine.

After a great battle, this place was dilapidated and collapsed. Unknown how many spiritual stones were destroyed, and many miners died.

In order to slow down the consumption of life span, Hydra is in a deep sleep state on weekdays and will only wake up when it encounters danger.

Although the mineral veins are exposed, there is a possibility of being targeted by the Poseidon Cult. However, the Netherworld mineral veins have been mined for more than five hundred years, and the good mining areas have basically been dug out. The rest are barren land, and there is not much profit to be made.

Moreover, he also severely injured the Soul Refining Demon Lord, who would never be able to make a comeback in a short time.

The only surprise was that a new pit was blown up, and ancient objects were hidden underground. Hydra made a prompt decision and immediately blocked the new pit, set up a shielding formation, and sent the news back to the top.

…………

When Xu Hei and his group arrived, it was already three days later.

This area of ​​​​the sea is extremely windy and turbulent, and sometimes there will be magnetic storms and lightning, and the ships will avoid it. However, the Nine-Headed Insect sailed the ship around, as if entering a formation, and the sea calmed down instantly.

The sun was dim and the sea was as calm as a deep pool, as if it was isolated from the outside world.

"This is the place!" said the Nine-Headed Insect.

A group of monsters immediately disembarked from the boat and dived towards the bottom of the sea.

It was pitch black under the sea, and the visibility was no more than a hundred feet. The monsters fell for more than ten thousand feet before landing on the bottom of the sea.

All I could see was that the seabed was filled with craters and countless mines.

Here, there are still violent spiritual energy fluctuations. It is obvious that a war broke out, and the huge pit in the distance also proves this.

Far away from the mine, there is a group of buildings with strange shapes. Some are human houses made of bricks and tiles, some are caves, some are shells, conches, fish bones, etc., and some are simply a sunken ship.

This is the residence of the miners.

The miners here are a group of creatures similar to fishmen, but they are smaller and more like frogmen.

"Look, an outsider has come in."

"Is this an outsider?"

"How amazing!"

A group of child-like frogmen walked out of the house and looked over from a distance. Living in a dark environment all year round, they have evolved excellent night vision capabilities and can clearly see the faces of Xu Hei and his party.

Xu Hei also looked over. The cultivation level of these frogmen was very low, most of them were at the foundation building level.

They are small and thin and can easily get into small caves. Their limbs are thick and they have evolved sharp claws, which are suitable for work such as mining.

They were born in the mining area and died in the mining area. They had never been out in their lives, let alone seen outsiders. At this time, their eyes widened, with both curiosity and fear in their eyes.

An old frogman flew out of the house. His cultivation level was the highest, and he was only at the foundation-building stage of Dzogchen.

"Everyone, the elder is in retreat. I have been ordered to lead the way for you. Come with me." The old frogman bowed.

Immediately, he didn't dare to look at everyone's glances and swam straight towards the huge pit in the distance.

Xu Hei and others followed.

It can be seen that although this old man has lived for more than a hundred years, it is his first time to see an outsider, so he is inevitably uneasy.

Xu Hei asked curiously: "Old gentleman, are there any monks in your race who are in the alchemy stage?"

"What is the elixir formation period?" the old frogman wondered.

"..." Xu Hei was speechless.

"No need to ask any more, they don't know anything." Nine-Headed Insect said.

Xu Hei fell silent immediately.

Not long after, they entered the deep pit and descended down. The terrain nearby was dilapidated, with various scratches and impacts everywhere, and the violent spiritual power lingered for a long time. It seems that this is where the battle took place.

Soon, the old man brought them to a covered formation and said, "Everyone, this is our destination. I'll leave!"

He returned the same way, swam upward, and quickly disappeared.

The Nine-Headed Insect explained: "These miners are a subspecies of the fishmen. They have thin blood and extremely poor talent. They will never be able to form an elixir in their lifetime. Even if there are a few geniuses who have a chance to form an elixir, the spiritual stones consumed by the breakthrough will There are too many, it’s impossible for him to form a pill.”

Xu Hei still didn't understand.

In fact, the operation of the Nether Mine has always been a mystery, but this vein, which continuously provides a large amount of spiritual stones and feeds half of the Penglai Sea, must have its existence.

Xu Hei didn't think much about it. This was not something he should worry about.

The shielding formation did not stop them, they easily passed through and came to an empty underground world.

This place is like a cave. There is no sea water inside and the air is humid. The stone walls are dotted with blue light, which should be some kind of metallic substance, slightly illuminating the space.

Yu Jianqiu took out a lamp, and the space suddenly became bright.

Xu Hei's eyes were fixed on the stone wall. He discovered murals one after another, and the others also looked at them.

"Is this the ancient picture that the intelligence said?" Yu Jianqiu raised his eyebrows.

"Master, can you see?" Xiong Dabao muttered.

"Shut up!" Yu Jianqiu scolded.

Different from the pictures Xu Hei had seen before, these pictures depict a scene of a human monk holding a sharp blade and fighting a ferocious beast.

"This is……"

Xu Hei's pupils suddenly shrank.

He actually recognized the sword held by the human monk in this picture.

——Dragon-slaying knife! !

Although there are slight differences from the Dragon-Slaying Sword in Xu Qingzhi's hand, it is generally similar and is definitely related to the Dragon-Slaying Sword.

The human monk holding the dragon-slaying sword was wearing a red robe, with angry hair and beard, and a dragon pattern on his forehead, which looked very much like Xu Qingzhi's fighting appearance.

Yu Jianqiu keenly noticed Xu Hei's emotional changes, but he didn't point it out, just smiled.

"Haha, it's actually a picture of an ancient monk fighting with a monster. Judging from the moves and actions, it should be left by a human monk for the purpose of showing his swordsmanship." Yu Jianqiu laughed.

In ancient times, humans and monsters were incompatible, and fighting between humans and monsters was a common occurrence.

Even now, in most areas, the relationship between the two sides has not improved, and only the Penglai Sea and Penglai Island are a special case.

Xu Hei didn't speak, and everyone walked straight into the depths.

Along the way, many murals were displayed, all of which were the same person, but the monsters were all strange, including dragons, tigers, cows, and birds.

It feels like a human monk who has fought with countless monsters and recorded them.

After a while, they walked to the deepest part and came to a secret room with many ice cubes inside, but the ice was not cold at all.

Everyone's eyes were immediately attracted by the ice cubes, and they saw that various strange monsters were frozen in the ice.

There were wolves with three heads, horses with wings, dragon-like and wolf-like beasts, colorful deer, and so on.
