Understanding Feng Wu's intentions, Chu Nan did not hesitate, and immediately swam over with him over there.

When he swam to the position that Feng Wuregret said, Chu Nan immediately realized something.

Because the current in front of me is extremely strong, it seems that the source of the entire lake is here.

Thinking of this, Chu Nan held his breath and struggled to shalve down more than ten meters, and immediately saw a whirlpool of water spraying in front of him.

Like the center of a storm, all the water is spewing out of here.

"It seems that the whirlpool in front of you is by no means so simple, it is very likely that the entrance to the Xuanyuan Relic Tomb is here!"

Chu Nan pondered for a while, and after making up his mind, a burst of energy erupted from his palm, and with the powerful thrust of the energy, almost instantly, his whole person plunged into the whirlpool.

And when he entered the whirlpool, he felt that things in front of him began to become calm.

When I opened my eyes, I found that there was a huge underwater palace in front of me, similar to the Dragon Palace of the East China Sea in the TV series, and the peace revealed a bit extraordinary.

And the plaque of the palace is impressively engraved with the four characters of Xuanyuan Hill.

What does Xuanyuan Hill refer to?

This has been clearly recorded in ancient books, and it is the residence of Xuanyuan Yellow Emperor.

That is, there is no doubt about the Xuanyuan Tomb!

Sensing that he was close to the destination of this trip, Chu Nan's eyes flashed with excitement, and with a slight movement of his toes, the whole person stabbed towards the palace.

But when he arrived at the gate of the palace, Chu Nan realized that he had thought things too simply.

Because the palace gate is closed, an extremely complex mechanism is arranged on it, and in order to open the gate, it is necessary to crack this mechanism.

Realizing this, Chu Nan had a headache.

Because along the way, he didn't know how many mechanism formations he had cracked.

originally thought that he was going to succeed, but if he wanted to take one step at a time, he had to crack the mechanism first wherever he went, isn't this a torture intention?

Just when Chu Nan wanted to cry without tears, Feng Wuregret finally caught up.

When he saw such an underwater palace, his face was also surprised.

I can't imagine how this palace was built, and if it were to be made public, it would definitely be one of the wonders of the world.

However, Chu Nan was in no mood to pay attention to the change in Feng Wu's expression, stood under the water, and carefully looked at the mechanism on the door.

This organ is similar to the organ of the Xuanyuan Ancestral Hall, and it is engraved with ancient characters.

It's just that these ancient characters are not the ones on the totem, but some completely new ones.

As we all know, during the reign of the Yellow Emperor, he opened up a lot of new things.

Words are one of them.

And the allusion of Cangjie characters comes from here.

It is said that Cangjie has two eyes and four eyes, and his appearance is very extraordinary, and from ancient times to the present, there are nine people with double pupils, such as Xiang Yu, Guan Yu, Li Yu and other historical celebrities are double pupils.

So Cangjie's life is destined to be the same as them, very extraordinary.

He developed Chinese characters based on the footprints of wild beasts, which played an indelible role in the reformulation of the script for later generations.

The words on the mechanism in front of him evolved from footprints.

It's just that these words are too obscure, so Chu Nan can't figure out what they mean for a while.

"Isn't it so complicated? If you don't know a little bit of history, the big living people really suffocate their urine!"

Chu Nan smiled bitterly, tortured by all kinds of organs.

If he hadn't come all the time, he would have wanted to leave in a hurry.

And just when Chu Nan was a little crazy, the closed door suddenly opened.

Chu Nan was slightly stunned, looked back at Feng Feng and had no regrets, it was this guy who quietly pressed the button on the side of the door.

"Your sister!"

Chu Nan's eyes widened, and when he saw this scene, he almost went crazy.

I thought that the mechanism on this door was the tool to open the door, but I thought it was as simple as pressing the button!

The door opened, Feng Wuregret seemed quite calm, and after glancing at Chu Nan, he stretched out his hand to signal Chu Nan to enter.

Seeing Feng Wuregret so calm, Chu Nan really wanted to give him a cannon kick.

Good guy, you wasted so many brain cells in vain, and you opened the door all of a sudden, and you didn't let yourself live?

However, when he wanted to return to his anger, seeing that the door had been opened, Chu Nan no longer hesitated, and stepped in with his legs.

Inside the palace, the water around you disappears completely.

It was as if it was separated by some kind of barrier, and even ordinary people could walk normally in it.

And this palace is not as luxurious as it looks on the surface, and when you enter the interior, it is a quaint hall.

The overall tone of the main hall is dark black, giving people an eerie feeling.

Maybe it's been abandoned for too long, or maybe it's sunk under the water for too long, the ground and walls are rusty, and the decaying grass can be seen everywhere.

Of course, none of this is important, the most important thing is that there is a bronze ancient coffin suspended in the center of the main hall.

The coffin is more than two meters long and is cast entirely in bronze.

The surface is carved with many lifelike dragons and ancient characters, which are combined with the totem of the Xuanyuan Yellow Emperor period.

"Brother Chu, what should I do next?"

Feng Wuregret couldn't hide his excitement in his eyes, he passed five levels and killed six generals, and now he finally saw the legendary Xuanyuan ancient coffin.

According to legend, this ancient coffin is not filled with a corpse, but the tomb of Xuanyuan Yellow Emperor.

After all, the Yellow Emperor had already ascended by dragon back then, and his physical body was not in the Nether Realm at all.

Only the things he wore during his lifetime remained.

These happen to be rare treasures of antiquity!

Chu Nan didn't answer, walked to the bronze ancient coffin, and tried to pull the chain.

This iron chain is made of 10,000-year-old cold iron, which is not only cold on the surface, but also quite amazingly hard.

However, this also shows that there is definitely something very important hidden inside, otherwise it would not have been so firmly sealed.

"I can only fight it!"

Chu Nan gritted his teeth, realizing the sturdiness of the iron chain, he simply didn't waste time, and forcibly urged the strange energy in his body, causing it to burst out of the dantian again.

I have to say that this strange energy is really obedient at the moment, and it was forcibly urged by Chu Nan, just like a flood of the sluice, a stream of brains surged from the dantian to his arm.

In an instant, the pain of the explosion once again swept through every nerve of Chu Nan.

made Chu Nan scream in pain, and while swinging his fist and slamming the chain, the whole person fell to the ground involuntarily.

"Uhh

The heart-rending pain made Chu Nan curl up on the ground, feeling like his body was about to explode, and the pain was unbearable.

"Brother Chu, what's wrong with you?

Feng Wu regretted seeing Chu Nan in such pain, and asked anxiously.

"I didn't ...... It's okay, I'm just kidney-deficient!"

Chu Nan was afraid of the wind and had no regrets, so he didn't tell him the truth, and subconsciously said what Li Mengmeng always said.
