Chapter 770 The trace of the key to the Asgard

"Did you leave some of that black crystal?"

As long as there is a black crystal, the system can easily determine whether it is a magic crystal.

However, facing Lu Fan's question, Hong Shuhui shook his head awkwardly.

"Your Majesty, that secret realm is very special. It takes a lot of effort every time you enter it.

And it is difficult to bring out that black crystal when you come out, and it will be severely rejected.

And even if you bring it out, for some reason, the energy in that black crystal will slowly dissipate and it cannot be preserved for a long time.

Later, our eight major forces studied it for a long time and found that that black crystal can only be refined in that secret realm..."

Hong Shuhui's answer disappointed Lu Fan a little.

Originally, I thought that Hong Shuhui had that kind of black crystal, and I could use it to determine whether that black crystal was a magic crystal.

But I didn't expect that the black crystal was so difficult to bring out.

Then Lu Fan asked in detail about the secret realm and the relevant information of this black crystal.

After hearing what Lu Lan said, Hong Shuhui knew the importance of this black crystal, and immediately told all the relevant information in detail.

According to Hong Shuhui, there are many large and small pits in the secret mansion.

There are black crystals in those pits, and there are also many places on the ground where black crystals are scattered.

However, according to the information they have investigated, the scattered black crystals on the ground should be brought out by the special beasts in the secret realm.

The beasts in the secret realm may have swallowed the black crystals and black energy, so they are all very fierce.

Even a strong man in the Refining Spirit Realm like Hong Shuhui dare not be careless in the secret realm.

Because there are special beasts in the secret realm that can kill them.

They saw two calf-like beasts fighting each other with their own eyes, both of them were at the peak of the seventh level.

The beasts at the peak of the seventh level are equivalent to the peak of the ninth level of the Refining Spirit Realm, and their real combat power is comparable to that of the human cultivators in the Spiritual Division Realm.

It was precisely because they had witnessed the battle between the two terrifying beasts that they did not dare to explore the secret realm recklessly.

If there was no existence in the secret realm that could pose a threat to them, they would have turned the secret realm upside down long ago.

When talking about the two beasts, Hong Shuhui's face showed an expression of fear that was difficult to conceal.

"Your Majesty, those two beasts are really scary. They are much stronger than ordinary seventh-level peak beasts. They are not on the same level at all. It's too scary."

"Fortunately, the two seventh-level peak beasts were only concerned with fighting and fighting, and did not deal with us, otherwise we might not be able to come out alive."

Looking at Hong Shuhui, who was full of fear, Lu Fan became more and more certain that the black crystal stone this guy was talking about should be the magic crystal, and that black energy must be the magic energy.

Thinking of this, he immediately made up his mind that he would definitely go to this secret realm to take a look after arriving in Black City.

Demonic energy and magic crystals are extremely powerful poisons for ordinary cultivators, but for him, there is no difference between magic crystals, magic energy and spiritual energy of spirit stones.

If there is a difference, perhaps the points obtained by recovering demonic energy and magic crystals are more than those obtained by recovering spiritual energy and spiritual stones.

After this thought flashed through his mind, he looked at Hong Shuhui and asked, "Is that secret realm in the hands of the Blood Evil Society?"

"No, that secret realm has a special key. Each of our eight major forces has this key, and we have agreed to explore it every six months.

There are less than six or seven days left before this exploration, and they should also rush to Black City with the key."

Listening to the news from Hong Shuhui, Lu Fan nodded, his eyes flashing.

This saves trouble.

Otherwise, he would have to go to the cities where the other six major forces are located to subdue and control them, which would waste a lot of time.

Now that the leaders of the six major forces are going to Black City, he will take this opportunity to catch them all in one fell swoop.

Just as he was thinking this, Hong Shuhui seemed to have thought of something and suddenly said:

"By the way, Your Majesty, a few years ago, a key appeared in the Black Domain. It is rumored that the key involves the secret of a fairy palace.

It's a pity that the key was taken away by a mysterious person as soon as it appeared. We guess that the mysterious person is likely to be the president of the Blood Evil Society."

"Key?" Lu Fan, who had just calmed down, was attracted by this news again.

Especially when Hong Shuhui said that this key involved the secret of a fairy palace, he immediately thought of the fairy palace key that triggered the system task.

At that time, the members of the Soul Palace were frantically pursuing the so-called fairy palace key, and he also searched the soul of a Soul Palace leader and learned this information from his soul memory.

In addition, it was learned that the Green Demon Leader might also have a fairy palace key in his hand.

It was because of this clue that the system task of collecting four fairy palace keys was directly triggered.

This proves that these four fairy palace keys and the fairy palace do exist.

It's just that he doesn't know where this so-called fairy palace is, nor what the so-called four fairy palace keys look like.

Therefore, it was very difficult to search, so he temporarily put this task aside.

After all, this task did not have any time limit, and it could be completed at any time.

But he never expected to hear the news from Hong Shuhui at this moment.

"Yes, that key appeared in the Black City, and it was originally going to be sold at an auction.

But then the auction was robbed, and the key disappeared.

But the person who snatched the key was not caught, so everyone speculated that the Blood Demon Society deliberately staged such a show and stole the key. "

Listening to Hong Shuhui's story, Lu Fan couldn't help but frown.

"Who took out that key?"

"I don't know. It is said that a mysterious person put it up for auction. In the end, the mysterious person didn't show up. He must have been silenced by the Blood Fiend."

"Mystery man?"

This answer made Lu Fan frown.

Who on earth is willing to put the keys to the Immortal Palace up for auction?

The person who can obtain the key to the Immortal Palace and know the secrets of the Immortal Palace will definitely not be a simple person.

It is impossible for such a being to auction the keys to the Immortal Palace for spiritual stones or ordinary resources.

Since it is not in exchange for resources, then why are the keys to the Immortal Palace put up for auction? Is there any other hidden secret in it?

After thinking for a long time and not getting any answer, Lu Fan could only suppress the idea for the time being.

No matter what the situation is, once you arrive in the Black City and take control of the Blood Fiend Guild President, everything will be known.

Thinking like this, he calmed down his thoughts and stopped thinking more, concentrating on continuing on his way with everyone.

After everyone walked forward for most of a day, several canyon passages appeared in front of them, leading to different places in the Black Territory and reaching cities controlled by several other major forces.

But now that he knew that the leaders of the six major forces and the president of the Blood Fiend Society would appear in the Black City, he was too lazy to go.

Once you get to the Black City, just catch them all in one go, which will save you a lot of trouble.

As for the treasure troves of these forces, there is no need to worry.

As long as the leaders of these major forces are suppressed and conquered, it will be very simple to plunder their treasure troves.

So Lu Fan and his party, led by Hong Shuhui, stepped straight into the canyon passage leading to the Black City...
