This battle can be said to be the most difficult battle for Yunfei since his rebirth, a battle of life and death.

The flesh was damaged, and the flesh and blood were torn off by the black dragon in many places, revealing the bones, which was only a superficial injury, and the more serious was the internal injury, the crystal bones were covered with cracks like spider webs, and the mental consumption was even more serious, if it weren't for the vigorous fighting spirit in his chest, he wouldn't be able to support it now.

As soon as his spirit relaxed, Yun Fei fell unconscious and fell on his back, but fortunately, the third girl quickly held him up.

This time he was injured, Yun Fei spent three days recuperating before he came out of a mysterious cave, with his kind of injury, if he were an ordinary person, I am afraid that he would have died in Huangquan.

Rao is like this, the black flame that penetrates into the bones and flesh will also bring him back to life, fortunately, there are red runes and the fountain of life to help, otherwise, the consequences are unimaginable.

"That black loach is really powerful!"

Yun Fei whispered, causing the little loach to roar in protest, it was very disgusted by this word, if it hadn't been able to take Yun Fei, it would have already begun to resist.

Yun Fei ignored him, Yuan Shen walked in the small world, looking at the black flame the size of a sesame seed, like a life, he touched his right earlobe and thought.

Ever since he imprisoned this sesame-sized flame in the small world, this guy has refused to surrender, and whenever Yun Fei approached, it would quickly dodge, and the speed surprised Yun Fei.

After trying many times, Yun Fei finally gave up reluctantly, it seems that it is not an overnight thing to subdue this little flame, I really don't know how Cai Guang subdued this sesame grain size black flame at that time.

If you have to endure hardship, you will become a superior person.

After experiencing severe pain that ordinary people could not bear, his physical body was once again tempered, his bones were extremely crystalline, and even some impurities in his bone marrow were removed, which was a situation that he had never encountered when he was quenched in the past.

In the past few days, Mu Tianxin's three daughters have been guarding him every inch and protecting him, which made Yunfei very moved, but it was just moving.

The area of the burial mound is vast, and the monotonous gray color fills the entire space, and countless remnant souls wander in it, disturbing the minds of spiritual cultivators who enter this space.

The four of them walked forward, and from time to time there were heroic spirits rushing towards them, for Yun Fei, although these heroic spirits were powerful, they could not pose the slightest threat to him, and they were shocked by his rich blood qi, he was like a humanoid true dragon walking in the heavens and the earth, and the ghosts retreated.

In the bones, pale golden bone marrow flowed, exuding a rich and terrifying bloody aura, which he deliberately did to shake those heroic spirits back.

It wasn't that he didn't think about getting some information from the remnants of those Heroic Spirits, but after a few attempts in a row, he gave up, because some of the remnants looked powerful, but there was nothing.

Of course, although those powerful heroic spirits have no inheritance, their strength is undoubted, and they incarnate into giant beasts and pounce, almost turning into entities, swallowing the sun and the moon, and eating away at thousands of stars.

These heroic spirits were just remnant souls, but it was Yun Fei's rich blood that attracted them, as if awakening their sleeping memories, to occupy this body.

Mu Tianxin's three daughters showed a difficult step, they had gone deep into the core area of the burial mound, the heroic spirits here were more powerful, more ferocious, several times, the three daughters were almost distracted, and were occupied by those powerful heroic spirits.

Fortunately, they persevered at the critical moment and drove away the remnants of the Heroic Spirits that had invaded their sea of knowledge.

"Zheng!"

The sharp blade roared, the ancient sword was sacrificed by him, the silver horse practiced across the sky, flashing with silver light rain, and all the heroic spirits that rushed to it were slashed away, and when he came here, his physical strength was not enough to resist those powerful heroic spirits, so he could only use the ancient sword.

Even in the battle with the black dragon, Yun Fei never used this sword, it can be seen that how powerful the heroic spirit here is, it is simply a bit outrageous, Yun Fei can't help but think about how many spiritual cultivators who enter here do not know how many people will die.

"Bell!"

A heroic spirit suddenly turned into a divine sword, the light was bright and dazzling, blooming with multicolored light, slashing towards Yun Fei, only taking the center of his eyebrows, the speed was three points faster than lightning.

"Whew!"

Yun Fei slashed horizontally, the two collided, and there was a piercing sound of gold and iron, bursting out a series of sparks, he blocked the attack, however, the center of his eyebrows was opened by the sword qi, and blood flowed sideways.

The sharp pain went straight into his mind, and his skull was about to explode, if there was no accident, Yun Fei would definitely be invaded by that heroic spirit and compete with him for control of his physical body.

If one doesn't get it right, he will lose his mind and become crazy like everyone else.

Of course he wouldn't allow such a thing to happen, the light of the ancient sword flickered, like a bright moon in the sky, spilling down an incomparably divine aura, enveloping his heroic spirit.

"Dragon Pattern Sword, how can this sword be in your hands!"

The heroic spirit shouted, very surprised, very suddenly, he actually had a spiritual intelligence, which shocked the four of them.

Walking into the depths of the burial mound, they encountered not ten thousand but thousands of heroic spirits, and those heroic spirits were all remnants of souls without intelligence.

"It's actually a heroic spirit with a spiritual intelligence, maybe there will be earth-shattering spiritual skills. ”

Yun Fei's hair stood upside down, and then his blood spurted, and the Thousand Illusion Hand unleashed his hand, turning into a big hand and grabbing the heroic spirit. Unfortunately, it failed, and the heroic spirit fled in a series of afterimages in a straight gray arrow.

"Be careful, it's not easy to have remnants here. ”

Yun Fei explained, and took the lead in marching towards the depths, he became the pioneer of the way, and the heroic spirits that pounced on him were shocked one by one, and even scattered.

Finally, on the way, I saw some people whose minds were not eroded and who were sober, and there were not a few of them, and there was no doubt that the people who were able to come here and whose minds were not eroded by the heroic spirits were all the best geniuses.

"A guy in the early stage of the Condensation Realm, a woman with three Little Spirit Heaven Realm who had completed their cultivation, was able to come here, I can't believe it. ”

When someone saw them, they let out a burst of exclamations, because most of the spiritual cultivators who were able to come here were strong people at the peak of the early stage of the Concentration Realm, even if there were one or two spiritual cultivators who had cultivated in the Perfection Mirror of the Little Spirit Heaven Realm, they all had spiritual energy to protect themselves against the remnant souls that rushed in, and people like the four of them who came here without precautions still belonged to another kind of existence.

"Isn't that guy the one who defeated Cai Guang?"

"It should be him, there are three beautiful women around him, and his appearance and height are also consistent with the description, it should be him. ”

Someone recognized Yun Fei and the four of them, and they were immediately surprised and turned into a natural look, after all, the battle with Cai Guang a few days ago had been spread by other spiritual cultivators, and basically most of the spiritual cultivators who were in the burial mound heard the news.

"He was not affected at all, one sword at a time, and slashed away all the remnant souls that rushed towards him, this guy really deserves to be a genius who defeated Cai Guang!"

Someone gasped, and there was a feeling of envy that could not be concealed between his words.

"Cut, if there are no rules to suppress here, just because he also wants to defeat Cai Guang, it's just beyond his strength. ”

Some people disdain it, thinking that Cai Guang is very resentful of failure, but unfortunately, there is no such thing as an if, Cai Guang is defeated after all.

Yun Fei didn't pay attention to those people's words, because it wasn't worth it, there was no need to talk to them, if they had any dissatisfaction, they could come and challenge him, and he would naturally take it.

Along the way, Yun Fei and the four of them also saw some spiritual cultivators, their faces were pale and even distorted, obviously fighting with the remnants of the soul who had entered the sea of knowledge.

They didn't disturb those people, and the remnant souls invaded the sea of knowledge, which was both dangerous and creative, and shared good and bad.

After walking for more than half a day, the four of Yunfei finally walked out of the core area with the most gray and the most heroic spirits, and what appeared in front of them was a patchwork of tombs with a height of several feet, which looked like a small mountain range connected to the horizon from a distance.

"There are so many tombs, it's so scary!"

Mu Tianxin was surprised, the tombs here are undulating, stretching for I don't know how many miles, and I don't know who did it, after so many years of baptism, those tombs that are very tall have no signs of consumption, only a few scattered weeds swinging with the wind in the wind.

"That's... Is that a burial grass?"

Hongluan stared at a pair of beautiful eyes, breathed heavily, pointed to a waist-deep piece of artemisia grass in the deepest part of the tomb, and exclaimed.

Following her pointing, I really saw that one plant was more than one person tall, the whole body was golden, the rhizome was crystal clear, exuding golden light, one stem and three leaves, and the edges of the leaves had serrated teeth stretching outward, like a round of scorching sun emitting golden light.

"It's the Burial Sun Grass, it's not so easy to get it!"

More than a foot away from the burial grass, there were more than a dozen people sitting cross-legged, with fine beads of sweat on their foreheads, and even a few people lying on the ground with their sunny faces, like fish out of the water, opening their mouths and breathing heavily.

Seeing the four of them moving forward, those spiritual cultivators could naturally see it, but instead of stopping them, they looked at them with a playful smile.

"Buzz!"

As soon as the four of them approached the range of the Burial Yang Caozhang, a buzzing sound sounded in the void, and then the shoulders of the four people sank, as if a mountain was pressing on their shoulders, extremely heavy.

"It's so heavy!"

Yun Fei was surprised, with his current physical strength and ability to resist pressure, although he didn't know how to carry the mountains on his shoulders, he also had a certain degree of resistance to pressure, but Rao was like this, his feet were still deep in the ground, straight into his waist.

Not to mention the three women, almost the whole person was pressed into the depths of the earth, and the scene of the four of them being embarrassed made the spiritual cultivators sitting cross-legged and pranayama in front of them laugh.

"I said brother, you just broke in so recklessly, aren't you afraid of being buried alive?"

Someone laughed out loud, they had suffered the same scene when they first entered this mysterious area, but fortunately, they had more or less protective treasures on them, so they resisted the coercion in the first place.

"Even if you die, why do you have to pull the three beauties on your back before you die, it's really despicable!" A sallow-faced, skinny young man laughed mockingly, and between his words, while expressing his dissatisfaction with Yun Fei, he also sighed for the fate of Mu Tianxin's three daughters.
