To put it simply, deep-sea oil lamps are extracted and then made into lamp oil.

But there are many differences between grease lamps. Among them, the lowest grease lamp is processed with general fish oil, and it does not have a unique aroma when burned.

Another type is to use deep-sea whale fish oil to extract it, which brings a fragrance. It can be used for a long time to calm the heart and wake up the eyes.

Xiang recorded in the strange book that during the Qin Dynasty, people caught a large number of dragon fish, used to extract oil from their bodies, and made copper oil lamps for use by the royal family.

The dragon fish is what people often call a mermaid.

It is said that mermaids often appeared in the sea in ancient times. Fishermen often saw them when fishing. Later, because they discovered the wonderful uses of dragon fish, they began to hunt in large quantities.

The dragon fish is good at weaving silk. The gauze that the weaving is not wet when it falls into the water and cannot be penetrated by water. It is the best in the cloth roll.

It also attracted much attention because of the tears falling into beads when they were crying.

Because of the various wonderful things of dragon fish, they suffered from family extermination, so they had the hatred of extermination between them and humans and had to live in seclusion.

The oil lamp that Xiao Yu saw now was not the thing on the body of the dragon fish, but the thing on the deep-sea water demon of the Sanhua cultivation level.

The deep-sea water monster is in the cold water ten thousand meters below. His body is thin, but his fat is the best in fat. He is used to make lamp oil. It can last for thousands of years and the cold air will not be stained.

The three-flowered monster, the peak of the earth immortal, is already the overlord of the ocean, and its strength is already great.

However, now I am so miserable that I have been slapped and used its fat to refine oil lamps. It is a bit creepy to think about it.

This cave obviously has some kind of formation, so the oil lamp will automatically ignite after the stone gate is opened.

The cold wind slowly disappeared after sweeping over, and the ice doors were all opened at this time, revealing a staircase made of thousands of years of black ice inside.

The stairs slowly move up, as if they lead to another place, but if you look carefully, you will find that the stairs have no foundation and just float in the air.

The thousands of years of ice hangs in the air, and only such a method can be done by an immortal.

On both sides of the surrounding walls, there are two huge corpses, two strange beasts with human bodies and fish heads.

However, the heavenly spirit cover of the strange beast had been cut off, and there was a wick as thick as a baby's arm inside.

"Good guy, he actually twisted the wick with the ten thousand-year-old fairy lantern grass. This ice demon is indeed crazy."

Xiao Yu couldn't help but exclaim.

When I heard the Wannian Immortal Lantern Grass, the ghost corpse's eyes lit up, and then sent a message:

"Since it's a ten thousand-year-old fairy grass, let's take it away?"

It is reasonable for the other party to have such an idea. Anyone who encounters such a treasure will be unable to help but grab it.

However, if you snatch it rashly, you will not only not be able to snatch it, but you will also be injured by it, because it is related to the production of lamp grass.

"It is said that the oil lamps in the fairy world are made of wicks made of ten thousand years of immortal grass. This wick is smokeless and tasteless and does not shake when encountering wind and rain. It only needs the length of your thumb to burn for ten thousand years.

However, most of these wicks are used in sacrifices because the sacrificial lamp cannot be extinguished.

Also, in temples, this kind of wick is also used to represent the eternal survival of incense.

What's more, you can put a trace of your soul in it, your soul will never die, and your wick will never die.

If the wick is gone, it means that it may fall or leave this world."

After Xiao Yu explained to the ghost corpse, he regarded this wick as his own pocket.

"So powerful, those two monsters look like things in the deep sea. It seems that they were made into oil lamps by the ice demon.

In this way, the ice demon is not a merciful person.”

As the two of them said, they stepped into the ice gate at the same time.

The ice ladder in front of me stretched upwards, not knowing where to go.

"Don't worry about that kind of wick first, go up first."

Oil lamps are used for lighting, and they may hide some mechanism. Once they touch something, it will be a big trouble for them.

The ice ladders are arranged upward layer by layer, although they are hanging in the air, but it is not much difficult for Xiao Yu and the others.

However, since the other party put the ice ladder here, he probably had his intention.

"I'll go first, just follow."

The ghost corpse stepped out and arrived at the first ice ladder, without any abnormality.

Then the other party shook a few times and continued to fly upwards for dozens of meters before signaling Xiao Yu.

Seeing that the other party was so safe, Xiao Yu took a long breath, then the power of the fairy spirit wrapped himself up, and with a bounce under his feet, the person rushed towards the first ladder.

However, when his feet stepped onto the ice ladder, a sudden force hit him directly.

Xiao Yu was suddenly hit by this force and his body retreated again.

"Gaga, the little little Taoist, you dare to step on the immortal ladder."

A sarcastic sound suddenly came from the ice cave, and then a white light flew out from the corpse with the fairy lamp grass inserted into it, turning into a man with a pockmarked face.

After Xiao Yu landed on the ground, he saw a handprint appearing on his chest and was shocked. If he hadn't had soft armor help, he would have been seriously injured just now.

"You are the guardian of the corpse. Since you know we are here, why don't you come to see you earlier?"

Xiao Yu looked at the man and said calmly.

"Hehe, wouldn't it be impossible to bring you in when you appear earlier?"

The man with a numb face floated around, and his voice was filled with a strange smile.

When Xiao Yu's expression suddenly tightened when he heard the other party's words.

"What's the meaning?"

Xiao Yu looked at his left and right and asked in disguise.

"What does it mean?

The Ice Demon Abyss is connected to the world, and the messenger can't survive."

The man with a numb face said to himself, and then Xiao Yu heard a rumbling sound, and the ice door suddenly closed just now.

Huhuhuhuhu...

Above the ice cave, around the ice ladder, suddenly several wicks lit up again.

At this time, Xiao Yu discovered that at some point, many guards appeared on the wall above the ice cave again.

However, the guards at this time were all humans, some of them were women, some were old men, and some were strange beasts.

Without exception, all the human celestial covers were removed, and a wick was inserted into it.

Xiao Yu looked at the people and his face suddenly became solemn, because those people were emitting white light, as if they were the most righteous fairy spirit.

But if you look closely, you will find that the pure fairy aura is mixed with some mottled spiritual energy, so they should be the peak of the earth immortals and have not yet broken through to the celestial immortals.

"Who are you and why are you in this situation?"

Xiao Yu took out the wooden sword and looked at the other party cautiously.

"Hehe, haven't you told you that we are the Ice Demon Messenger here, and you are the next one."

The man with a numb face looked at Xiao Yu, then his mouth suddenly cracked, and then his body rolled, turning into a huge black whale shark.

Behind the whale shark, endless sea water suddenly rolled up and swept towards the location where Xiao Yu was.
