After thinking hard for a while, Xu Han finally had an understanding.

"I see!" Xu Han walked back and forth in the palace hall with some excitement, his eyes flashing: "The secret treasure of the sky, the essence of the sword, these two sentences are just information related to the secret treasure, and the last two sentences are the way to find the secret treasure!"

"A moonless night, in the core of stone. The corners of Xu Han's mouth lifted slightly, and he already understood the essence of it. If the stone mountain is regarded as a stone core, then the whole sentence is easy to understand - on a moonless night, there will be a shocking treasure in the stone core.

Moonless Night!

Xu Han suddenly found this problem and couldn't help but tremble. As we all know, the moon is cloudy and sunny, but it is the Sword Dust Continent, and in the Martial Realm, the bright moon is always a full moon. Because the martial realm is a secret realm, it is not exactly the same as the real world, there are no four seasons in the martial realm, the four seasons are the same, only different regions will appear different weather.

How can a place where the full moon is always present have a moonless night?

Puzzled, Xu Han summoned Yuebai Fansu.

"Excuse me, what's the matter with me?" asked Fan Su respectfully. Xu Han's identity in Yuebai Mansion was so special that he couldn't think of any good names.

"Fan Su, let me ask you, is there a moonless night in the Martial Realm?"

"Moonless Night...... "Yue Bai Fansu's face showed hesitation.

"How?"

"Nothing. Yuebai Fansu said solemnly: "In the martial realm, there is indeed a saying that there is no moonless night. ”

"Saying?" Xu Han frowned involuntarily: "It's just a statement, hasn't it really appeared?"

"No, it's just that I haven't seen it. Yue Bai Fan shook his head: "Legend has it that there will be a moonless night in the martial realm every hundred years, which is called the Great Dark Sky by the world, and it is a wonder and vision that can only be encountered once in a hundred years. ”

"Oh, has anyone seen this big dark sky?"

After pondering for a moment, Yuebai Fansu replied: "When I was a child, I heard my father talk about the dark sky, but my father never saw it. ”

"That'...... Where did your father find out?"

"From the mouth of my grandfather. Yuebai Fansu said: "He was the lord of Yuebai Mansion. ”

"In this way, there is indeed a zài on a moonless night. Xu Han muttered in his mouth, and couldn't help but fall into deep thought again.

"Excuse me, what else do you have to order?" Seeing that Xu Han didn't speak for a long time, Yue Bai Fan couldn't help asking.

"No, you go down first. Xu Han reacted.

"Got it. With a response, Yuebai Fansu withdrew from the palace.

Xu Han's face was full of suspicion, he paced back and forth, and whispered in his heart: "According to the words described on the stone core of the Tianhai Forest, at the time of the Great Dark Heaven, a secret treasure of heaven will appear in the stone core, but this Great Dark Sky is indeed a once-in-a-century spectacle, and the last time the Great Dark Sky appeared, it was when Yuebai Fansu's grandfather was the lord of the Yuebai Mansion, that is to say, it has been almost a hundred years now. ”

He sat down, picked up a teacup, and studied it carefully.

"After Qu Mingchun and Nelly escaped from the Bloody Night Mansion, they privately built the Tianhai Mansion in the Tianhai Forest, and recruited the scattered people who had no mansion to rely on, and formed a scattered force. He deliberately concealed the location of the stone core, indicating that he had known the secret of the Tianhai Forest for a long time, and this secret was most likely heard by him and Nelly in the Blood Night Mansion. ”

However, Xu Han thought that what Qu Mingchun and Nelly said was not a lie, they were just hiding the secrets of Tianhai Forest. Because, a person may be able to hide his expression, but the eyes of hatred cannot be faked.

It can be boldly guessed that Qu Mingchun and Nelly learned that the real culprit of the Killing Fox Mansion was the Bloody Night Mansion in the Blood Night Mansion, however, they also understood the strength and horror of the Blood Night Mansion, and they could only hate it in their hearts.

However, one day they accidentally learn the secret of the Tianhai Forest, which directly prompts him and Nelly to defect. They fled to the Tianhai Forest, privately built the Tianhai Mansion, and co-opted the scattered forces, in addition to fighting against the Blood Night Mansion, the more important reason was the secret treasure hidden in the stone core of the Tianhai Forest.

Because, with the power of the Sanren alone, even if the Sanren gathered in the entire Martial Realm, they would not be able to oppose the Blood Night Mansion at all. So, he and Nelly pinned their hopes on this secret treasure.

The Secret Treasure of the Heavens, the Essence of the Sword, Xu Han has not yet fully comprehended the essence of it, but from a literal understanding, he can conclude that this Secret Treasure is extraordinary.

However, they also learned the secret of the Tianhai Forest from the Blood Night Mansion, which also means that the Blood Night Mansion also knows this secret. If this secret treasure could really threaten the Blood Night Mansion, they would not sit idly by and ignore it.

Qu Mingchun and Nelly said that the Blood Night Mansion had already discovered that they had privately built the Tianhai Mansion in the Tianhai Forest, but they had never made any moves. But if they don't sit idly by, how can they do nothing?

Unless......

At this time, Xu Han raised his eyes, and his pupils were extremely deep: "Unless, the Blood Night Mansion knows the exact time when the Great Dark Sky will appear." ”

Only this one possibility can explain a qiē.

Qu Mingchun and Nelly only knew the approximate time when the Great Dark Sky appeared, but the Blood Night Mansion knew the exact time. Therefore, when they learned that Qu Mingchun and Nelly had built Tianhai Mansion privately, the Blood Night Mansion did not make any moves, but they destroyed the Mansion a while ago and razed Tianhai Mansion to the ground.

"Could it be that the Great Dark Sky is about to appear?" Xu Han suddenly stood up, his eyes full of shock. The Blood Night Mansion knew the exact time when the Great Dark Sky appeared, and for this reason, they had turned a blind eye to the private construction of Tianhai Mansion before, and it was also for this reason that they destroyed Tianhai Mansion.

So, in other words, the Great Dark Sky is about to appear in the near future! That's why the Bloody Night Mansion will take action!

Qu Mingchun and Nelly were about to leave before their injuries healed, probably because they smelled the smell of the Great Dark Sky from the actions of the Bloody Night Mansion.

"When the dark sky appears, there will definitely be another bloody storm. Xu Han's expression was solemn, and he poured out deep words in his mouth.

For those who don't know the situation, the Great Dark Sky is just a spectacle, but why is there such a spectacle every 100 years?

Xu Han felt that the connection between the Great Dark Sky and the Heavenly Secret Treasure was not a coincidence, it was likely that they were closely linked in a very distant era, and this era was even very likely to be the beginning of the opening of the Martial Realm.

If the Martial Realm is a secret realm opened up by a strong man above the Soul Realm, then the rules of the Martial Realm will also be created by this person. For example, a secret treasure of heaven descended in a hundred years, and the strong of all parties fought for it. And the Great Dark Sky is the signal of the arrival of the secret treasure.

Thinking of this, Xu Han couldn't help but take a deep breath, and his heart was extremely shocked, and he couldn't stop for a long time.

If a strong man who has reached a certain realm can really open up the martial realm and create rules, then what is he Xu Han in this world? For the martial realm, that strong man is simply like a god, and it is not an exaggeration to even call him a god. And he, Xu Han, is just a drop in the ocean, just a chess piece in the chessboard arranged by others, at the mercy of others.

Xu Han felt infinite emotion in his heart, and he began to feel that the realm of the strong is not a division of levels between people, but a ladder to the world. With each step, you get closer to the world.

Barbarian realm, untie the shackles of human bodies and gain infinite power.

Qi realm, untying the shackles of the human dantian, can give birth to sword qi.

The spiritual realm, untie the shackles of human brains and comprehend the laws of heaven and earth.

True Boundlessness, untie the shackles of the human being's qi sea, and filter the true qi from the law aura.

There is also the Void Realm, the Soul Realm, and the realm above the Soul Realm that Yuntian's predecessors said. When human beings reach the supreme realm with their own strength, they will also gain supreme power, destroy the heavens and the earth, split mountains and rivers, wave their hands and scatter millions of corpses, and even more, open up the secret realm and create the rules of the secret world.

At this time, Xu Han's strong heart became restless. He aspires to be strong and strives for the top. And the pinnacle of his dreams is not the spiritual realm, not the true realm, not even the realm of the void, but the supreme realm that surpasses the soul realm. That is the strength that Xu Han really yearns for.

With the absolute power to control a qiē, and look down on all living beings! Only those who really stand at the top have this qualification!

Xu Han took a deep breath to calm his mood, only when his mind remained absolutely calm could he think correctly. Right now, both the Moon White Mansion and the Butterfly Shadow are threatened by the Blood Night Mansion, and Xu Han wants to resolve this crisis.

The power of the Blood Night Mansion is very terrifying, and if he wants to fight against it, his current strength is far from enough. However, if that Heavenly Secret Treasure was really a treasure that could make the Blood Night Mansion jealous, it would be very necessary for him to fight for this secret treasure.

With the Yinyuan Sword and the Heavenly Secret Treasure, even if he still can't compete with the Blood Night Mansion, he will be able to buy himself more time, and use this time to continuously cultivate and improve his strength. In this way, before the Blood Night Mansion sent out the True Boundless Ninefold Master, Xu Han could ensure the safety of the Moon White Mansion and Butterfly Shadow.

Suddenly, Xu Han's heart trembled fiercely, and his face turned pale in an instant!

At that moment, a terrible message flashed through his mind!

Assuming that his guesses were all true, and the Blood Night Mansion knew the exact time when the Great Dark Sky would appear, and this time was coming, then, after the Blood Night Mansion destroyed the Tianhai Mansion, it was impossible not to send someone to stare at the stone core of the Tianhai Forest.

Other words......

Xu Han couldn't help but gasp, "There are people near the stone core, and they have already found me!"

The Blood Night Mansion will definitely send someone to keep an eye on the stone core, in this way, the news that Xu Han discovered the secret of the stone core will also be known by the Blood Night Mansion, if the one who is staring at the stone core is a master who is very good at concealing the aura, then he is likely to have been followed, and even the location of the Moon White Mansion has been exposed.

Xu Han's head buzzed, he sat down in a daze, and muttered, "Oh no...... There will be a disaster in the Moon White Mansion!"
