This black abyss was too deep, and he swooped down for dozens of miles before reaching the end, until more than three hundred miles, he finally saw some vague scenes, this is a wide underground cavern.

As soon as he landed, Fusu suddenly felt a mysterious power, coming from these stone walls on the edge, and to his surprise, there would be a rune flash on the stone wall every once in a while, emitting light and circulating mysterious power.

"These are the laws of the Great Dao, but the Great Dao of this heaven and earth has long ceased to manifest, how can there still be the Law of the Great Dao here?" Fusu's heart shook.

"Hey, no, these Great Dao laws don't come from heaven and earth, they seem to be artificially cultivated," Fusu came to an astonishing conclusion after exploring for a long time, these laws lack the true meaning of the Great Dao, just like a person is not angry.

His face turned different, and then he turned his heart on fire and continued to investigate.

"This may be the means left by the Great God of Fuxi," Fusu secretly guessed, whether it was Fuxiqin who could react with the Zhentian Monument, or the blood of its inheritor Yemei who could open the barrier of this black abyss and collect the Zhentian Monument, etc., it all showed that this place was absolutely inseparable from the Great God of Fuxi.

Suddenly, his pupils contracted suddenly, staring at the cave wall, as if he had found something, his face was filled with shock, "This stone wall has an indescribable avenue charm, which is extremely mysterious, and this charm does not come from those law runes. ”

"This is the Tianyuan Stone?" Fusu finally recognized the origin of this cave wall, which was simply earth-shattering, making him unable to calm down.

"Oh my God, how can there be a Tianyuan Stone in this place?"

The so-called Tianyuan Stone is produced with the Heavenly Vein, which is hard to imagine, and its value is simply incalculable, and it can be compared with the Chaos Stone and the Primordial Stone, and it is one of the ultimate stones, and it is a natural treasure rough embryo.

"According to rumors, this world has given birth to ten heavenly veins, is it true? But how can this be ......" Fusu's heart set off a stormy wave, the heavenly veins, the world's top and most mysterious and infinite spiritual veins, contain the power of the Supreme Dao, extremely precious, but this kind of thing is difficult to generate, even the endless chaotic void, it is impossible to have.

He didn't believe that there were Heavenly Veins in this world, but the Tianyuan Stone Cave Wall told him that this was the truth, that this world had indeed given birth to Heavenly Veins, and even rumors were true that there might be ten Heavenly Veins in this world.

"This is the Tian Yuan Stone, which means that this is where the Tian Yuan Tian Vein is, but this place is empty, and there is not even a little Tian Yuan Tian Vein left, so where did this Tian Yuan Tian Vein go?" Fu Su looked around, with a puzzled expression, if he could get this Tian Vein, then the help to him would be unimaginable.

"However, the birth time of this celestial vein should not be long, and there is no will to be born," glanced at the wide cave, Fusu muttered to himself, according to the ancient books, the completely grown celestial veins have countless hundreds of millions of miles, and they are unimaginably large.

But I have to say that this cave is very big, he has explored for a day and a night, and he has not yet reached the end, and finally, he spread his wings and flew into the depths, the chaotic qi is getting thicker and thicker, if it weren't for the primordial qi in his body and the thunder pool above his head, he would have been flattened by this chaotic qi a long time ago.

It didn't take long for him to see two bronze gates, and there was a faint light shooting out from them, and he was a little surprised, he quickly flew to the front, and looked carefully, the two ancient bronze gates were slightly open, and they were not completely combined, and the breath of time flowed on them.

After a moment's pause, Fusu stepped sideways through the gap.

When he stepped inside, he was a little surprised, behind the door was a temple, immensely large, with mysterious power, but the temple was empty, and there was almost nothing at a glance.

"Who built this temple? Could it be that it was also built by the great god Fuxi?" Fusu was a little surprised, slowed down and walked through the temple, looking around.

Soon, he discovered the source of the light in the hall, more than a thousand meters away from him, there was a large stone platform, on which were placed three mysterious metals, exuding misty brilliance, there were runes circulating, the scene was amazing.

Seeing which three kinds of metals, the excitement in Fusu's heart could not be suppressed, it was very likely that it was three kinds of immortal gold, which was a treasure that he desperately needed.

"Dao Xuan Black Gold, Feather Immortal Gold, Taiyi Soul Gold," Fu Su stepped forward and looked at it, and was immediately stunned, frozen in place, these are three ultimate immortal materials, each of which can shake the ancient and modern, and take out one at will will make those emperors red-eyed, and they will fight, fight, and fight desperately because of this.

"Shhh

"These things, there are only some records in ancient books, and I'm not even sure if they really exist, but I didn't expect to meet them today," Fusu gasped and felt ecstatic in his heart, these are all top-level ultimate immortal materials.

"The catastrophe has started, the demons are dancing wildly, the heavens and the earth are chaotic, it's time for me to prepare one or two divine weapons for myself," Fu Su took a deep breath and ran the thunder pool to collect the three ultimate materials.

The ultimate material is not something that ordinary people can collect, and it is even more difficult to refine it into a divine weapon, but Fusu has this thunder pool, and he can barely collect it, the key is that he can also refine it, because in addition to the thunder and lightning in his thunder pool, which is the most extreme thunder and lightning at this time, the divine fire inside is also very powerful, and it can incinerate everything, and the most important thing is that everything in the thunder pool will not be affected by the rules outside.

Collecting these three materials, Fusu struggled, and finally used several drops of essence blood, and after about three or four hours, he put these three kinds of immortal materials into the thunder pool.

"When I get the Blood God Sword, I can start refining my own divine weapon, but I don't know if the Blood God Sword has given birth to a weapon spirit, if I already have a weapon spirit, then I have to find other materials, otherwise it would be a pity to destroy it," Fusu was very weak, but he was in a good mood.

"Huh?"

"That's ...... Whose bones?" Out of the corner of Fusu's eye, he suddenly noticed a sitting corpse not far from him, and he quickly stepped forward.

The tall corpse bones have been decayed, but there is still a faint aura of Dao rhyme on it, obviously, this person was once definitely a great power.

Fusu urged his heart to his eyes, carefully observed this corpse, and became more and more shocked, there is an immortal breath on this corpse, then this person's cultivation is afraid that it is not much different from those gods and demons when the world was opened, but he actually died here, and the bones are decaying, what is going on?

"Could this be...... The bones of the great god of Fuxi, right?" Fusu's pupils shrank suddenly, the great god of Fuxi was one of the ancient gods, and from the Fuxi qin he refined, he could see how unfathomable his cultivation was.

"Whether it's or not, since it's a deceased person, then let me help Su worship," Fu Su thought to himself, the three immortal materials in this temple may belong to this person, and he took these three immortal treasures, which is equivalent to receiving the great favor of others, and he should be thanked.

But at this moment, Fusu heard a strange noise coming from outside the door.

"Ah......h

Then, a woman's scream followed.

"Yemei!" Fusu instantly judged the owner of the voice, and immediately turned his head to look at the direction of the bronze door.

"What the hell happened?Why did Yemei come in?Could it be that a master appeared, and Dugu Invincible couldn't resist it?" Fusu began to feel a little anxious in his heart, and then he was about to leave and go out to have a look.

It's just that before he could take a step, a ball of golden light flew in, and Fu Su was stunned for a moment, it was Fu Xiqin who came with Ye Mei, and came in the blink of an eye.

"What's going on?" Fusu hurriedly stretched out his hand to support her and asked;

"I'm scared to death, black-bellied man, you're not dead yet, I'm scared to death," the girl hugged Fusu with a crying voice, her voice choked.

Fusu's face darkened instantly, what do you mean that you are not dead yet? Could it be that this thing thinks he is dead?

"Alright, alright, tell me what the hell is going on?" Fusu said angrily, tapping her forehead;

"I don't know what's going on, Fu Xiqin took me down, almost scared me to death, this place is not dark, it's still so deep," the girl said indignantly;

"Knock! knock!"

At this moment, Fu Xiqin made a mournful sound, Fu Su and Ye Mei suddenly looked up, only to see Fu Xi Qin vibrating, spreading a sad emotion, Fu Su and Ye Mei were both infected.

"Could it be that this is really the bones of the great god Fuxi? That's why Fuxiqin made such a sad voice," Fusu was shocked, although he had such a guess in his heart, but after it was confirmed, he was still a little shocked.

"Black belly man, what's wrong with Fu Xiqin, how do I feel as if it's sad," Ye Mei said in a low voice.

"Rustling ......"

Suddenly, the bones on the ground began to weather.

"Beware of the Chaos True Spirit!"

Before Fusu and Yemei could react, such a voice sounded in the hall, and at the same time, the weathered bones began to shine, and then a golden scroll flew out of the bones, and the scroll automatically dispersed, it turned out to be a golden paper, but there was no writing.

"What's going on?" Ye Mei was a little stunned, and then, a golden light shot into her eyebrows, she screamed and fainted, Fu Su hurriedly reached out to support her, and at the same time put away the golden paper, and all the bones on the ground were turned into ashes, and Fu Xiqin then returned to Ye Mei's body.

Fusu is now almost certain that the dissipated bones are nine out of nine Fuxi gods, and he sighed a little, the dignified generation of gods will actually sit in this place, but the cause of his death, Fusu feels extraordinary, there must be some earth-shattering secrets in this.

"It's just the Chaos True Spirit he was talking about...... Could it be that it refers to a certain person, or is it a creature that has survived from ancient times? But judging from the word chaos, it is most likely the latter" Fusu whispered, and then his eyes narrowed, "Could it be that the death of the great god Fuxi has something to do with it? And he is sitting here just to warn future generations?"

"Also, what secrets are hidden in this golden paper? It is necessary for the great god Fuxi to hide it in the skeleton," Fusu then took out the golden page, flipped through it, and frowned, "It seems that we need to take some time to explore the mystery,"

Fusu put away the paper, bowed three times to the place where the bones were before, and after glancing at the temple again, he found that there was nothing else, so he left with Yemei, but he was a little worried about this Tianyuan Stone in his heart, and wanted to take it away, but the wall of this cave was too big, and with his current strength, he couldn't take it away.
