Lu Feng and Xu Man traveled nearly a hundred miles in the space below the Great Dao River, and Lu Feng gained very little.

The abandoned holy mine did not have much value, which made Lu Feng's heart inevitably a little disappointed, and he even wanted to go to those cracks to see if there were any top-grade holy stones.

It's just that it's too treacherous, and besides, it's an abandoned holy mine, and even if you venture into those cracks, it's unlikely that anything surprising will come of it.

"Qing Barge, they should have arrived at the source of the Great Dao River. ”

Lu Feng whispered to himself, he swept under the Great Dao River, and the speed of Qinglu was much faster than his own, and he should have come to the source of the Long River at this time.

He was already disappointed with the space under the Great Dao River, so he unfolded his body and swept away in the direction of the source of the Great Dao Long River.

"Wait a minute!"

Lu Feng said suddenly, and he found a warm yellow light shooting out from a crack.

This beam of yellow light is very special, different from the light emitted by all mountain stones, and the fluctuations revealed are very mysterious.

"What's the matter, young master?" asked Xu Man, his figure abruptly stopped.

"Go there and have a look!"

Lu Feng said, he sensed that this light was unusual.

A moment later, Lu Feng came to the top of the crack, and the source of this light seemed to be at least a thousand feet deep.

"It's like a good holy stone, but it's also a waste stone, but the light it emits is more special. The Burning Immortal Sword Spirit said.

Although this warm yellow light was unusual, it was not entirely certain that it was a superb holy stone, and there were some worthless strange stones here, perhaps the stone below was one of them.

Only by holding this stone in front of your eyes and grasping it in your hands can you determine its value.

Moreover, the power of the Great Dao in the crack was extremely violent, and even a strong person at the peak of the Enlightenment Realm could die inside.

"Let's see. ”

Lu Fengdao, he had already made up his mind, this was the last time, if the stone below was still of no value, he decided not to look for the holy stone, and went directly towards the source of the Great Dao River.

"Young master, I'll go down with you. Xu Man said.

Lu Feng nodded, the power of the Great Dao in the crack was terrifying, and Xu Man's dragon body was quite strong, Although it was a bit risky, the two of them together were undoubtedly safer.

Immediately, Lu Feng and Xu Man jumped down, surrounded by Dao Laws, runes condensed, and the power of the Great Dao hit it, emitting bursts of humming.

"The sun is shining!"

Lu Feng shouted, and the first sword style of the Burning Immortal Jue was unleashed, the blazing sun crossed the sky, and the golden crow spread its wings and rushed downward, tearing a hole in the power of the violent avenue.

If you are outside, a distance of thousands of feet, the land breeze can cross in an instant, but here it becomes extremely difficult.

Rumble!

The sword qi blazing sun collapsed, the shape of the golden crow was destroyed, Lu Feng's eyes were sharp, and the double sword slashed, the sword was shocking, breaking through the power of the avenue, and rushed straight down.

The source of that beam of yellow light, located in a small gap in the stone wall, Lu Feng stood on the cliff and saw a round strange holy stone.

Burst!

Lu Feng let out a muffled snort, a trace of blood overflowed from the corner of his mouth, he rushed to this place, but he was also injured by the power of the Great Dao, and several blood streaks appeared on his left shoulder.

Xu Man was also affected, and his scales shattered, and dark red blood flowed out.

"It's ...... Xuanhuang Mother Stone?" In the space of the Burning Immortal Sword, there was a stunned voice of the sword spirit.

At this time, Lu Feng didn't care what kind of stone it was, grabbed this round stone, and his figure rose into the air.

The runes around his body couldn't stop the impact of the power of the Great Dao, Lu Feng's face was slightly pale, his muscles were cracked, and blood was constantly spilling out of his mouth.

If it weren't for the Burning Immortal Sword and the Robbery Immortal Sword, Lu Feng would even have to be buried here.

"Young Master come up!" Xu Man shouted.

In terms of physical strength, even Lu Feng can't compare with Xu Man, Lu Feng's injuries are more serious than Xu Man's.

Lu Feng stepped on Xu Man's back, Xu Man roared, the dragon chanted and shook the sky, soaring into the air, and the power of the Great Dao hit his body, making a sonorous sound.

Bang!

Xu Man flew out, landed on all fours, made a dull sound, the dragon's body trembled, and a large mouthful of blood spat on the ground.

"Damn, if it's a broken stone, it's too much of a loss!"

Lu Feng gasped and couldn't help but scold.

He did not hesitate to venture into that crack, and after being so seriously injured, there were no less than a dozen cracks on his body, and if it was just a stone of little value, it would be a loss of blood.

"It's a Xuanhuang motherstone, although it's not very pure, it's also quite rare in the cultivation world. The Burning Immortal Sword Spirit said.

When Lu Feng heard this, his eyes were shocked, and from the words of the sword spirit, he could hear that this stone seemed to have some value.

"What is the Yellowstone, and what is it for?"

Lu Feng asked, when he was in the cultivation world in his previous life, he had never heard of the Xuanhuang Mother Stone.

The Burning Immortal Sword Spirit said: "The Xuanhuang Mother Stone is also a rare treasure in the Desolate Realm, this kind of stone not only contains great creation, but also contains a trace of the origin of the Great Dao. Before stepping into the Dao Void Realm, when condensing the Dao Seed, if there is a Xuanhuang Mother Stone, it will undoubtedly be much easier to condense the Dao Seed, and it will bring great benefits to the cultivation after the Dao Void Realm, and your luck is not bad. ”

Lu Feng's eyes swelled with a touch of joy, he was condensing the Dao Seed, this Quick Xuanhuang Mother Stone was just right for him.

The hard work paid off, and it was not in vain that Lu Feng entered the space under the long river of the Great Dao, and went deep into the danger to get this stone.

"It's just that there are too many impurities in this Xuanhuang motherstone, which is not pure enough, and it belongs to the low-grade Xuanhuang motherstone. "Sword Spirit Dao.

Lu Feng held the Xuanhuang Mother Stone, which was no more than the size of a palm, and a trace of true qi poured into it, feeling the trace of mysterious aura inside, and the corners of his mouth raised a trace of arc.

"Congratulations, young master, with this thing, young master will be able to step into the Dao Void Realm faster. Xu Man said, the blood stains all over his body and the sharp pain from the wound made his facial expression distorted, but his eyes were surging with joy.

A devouring force erupted in Lu Feng's hands, and wisps of mysterious aura could be seen, overflowing from the Xuanhuang Mother Stone and inhaling into Lu Feng's body.

This is the breath of the origin of the Great Dao, mysterious and mysterious, even with Lu Feng's current perception and understanding of the Great Dao, it can't be penetrated, but these breaths can be used by Lu Feng and gathered in Lu Feng's dantian.

It can be clearly felt that the speed of condensation of the Dao seed has become faster, and a seed the size of a needle tip has formed in Lu Feng's dantian!

It was the prototype of the Dao Seed, and after the breath in the Xuanhuang Mother Stone entered Lu Feng's body, the prototype of the Dao Seed quickly condensed, making Lu Feng feel pleasantly surprised.

If there is no Xuanhuang motherstone, it will take at least a month, or even several months, to condense the prototype of the debut species, if you are not lucky enough, it is not impossible to drag it for a year and a half.
