The Fire House Demon Hell is an underground world with a vast radiation, spanning twenty-one states, with countless entrances, and occasionally on full moon nights, under the leadership of some demon powerhouses, rush to the surface and plunder.

The closest entrance to Xuanming Valley is 1,800 miles away, if Luo Feng and Huang Quan are in a hurry, I am afraid it will take a lot of time, but with Tu Bailing, an elder and child with a solid net worth, with the help of her flying spirit weapon Colorful Neon Clouds, it will arrive in less than half an hour.

The entrance to the Fire Mansion Demon Hell was a deep pit, as if it had been hit by a meteorite, with a diameter of more than ten zhang, and the demonic energy of the forest burst out from it, spreading in all directions.

The nearby environment is affected by the demonic energy, the soil turns black, the river dries up, the air is turbid, and even the trees that grow are deformed.

A few old trees reflect the remnants of the sun, several colorful clouds drift far away, the barren fields are lonely, and the ancient ferry is desolate.

After Luo Feng came down from the flying spirit weapon, he didn't have time to appreciate the decaying scene with a unique charm nearby, he felt an invisible energy sweeping over his body, and his flesh and bones became more active than ever, as if he had been stimulated by acupuncture.

He raised this question, and Tu Bailing explained: "It is said that it was caused by an extraterrestrial meteorite seven hundred years ago, and the current gap is left at that time, and the meteorite has been smashed to the ninth layer of the Fire Mansion Demon Hell, and it was blocked by the Heavenly Demon Great Barrier before stopping, but the hole on the second to eighth floors has been filled, and if you want to go down, you still need to find another passage."

Meteorites outside the sky will take the initiative to emit strange energy, if mortals are in contact for a long time, the body shape will be abnormal, and the offspring are also prone to deformity, in fact, there are many animals in this wasteland that have suddenly become monsters, such as thumb-sized hyenas, four-pair winged pheasants, buffalo-sized toads, which look very much like demon beasts, but in fact have no demonic power.

However, this energy is very beneficial to us monks, especially martial cultivators. The reason why it is harmful to mortals is because mortals do not know how to manipulate mutations, and once the flesh and blood become active, they will fall into disorderly changes, which will eventually lead to changes in body shape, but the grasp of the body of our generation is like a pattern in the palm of the hand, which can guide this kind of mutation and move in a beneficial direction. ”

Luo Feng tried to feel it, and confirmed Tu Bailing's words, and the stimulated essence blood was transported extremely smoothly, two points faster than usual.

The goal of martial arts training is to stimulate potential and break through the limit again and again, and for this purpose, it is necessary to perfectly exert the power of every flesh and blood.

Stimulated by this strange energy, some parts of the human body that cannot be exercised on a daily basis, such as the internal organs, also woke up from the silence and became active.

This process can save a lot of time for martial arts cultivation, and to achieve this kind of process on weekdays, you need to run your true qi and practice martial arts over and over again until your essence qi melts into your bone marrow.

What Wu Xiu is afraid of is not change, but dead and still, this strange energy can just break the calm and break the framework that has existed in the human body since its birth.

Of course, if the strange energy is too powerful, the active process of flesh and blood is beyond the control of martial arts, and it will also fall into a rampage, resulting in unexpected mutations.

Huang Quan was about to take the lead, but Tu Bailing hurriedly stopped: "Wait a minute." ”

She pinched the magic trick and summoned the yin thunder to throw it along the tunnel, and she heard a boom, crackling electric snakes scurrying away, accompanied by the wailing of many beasts.

"According to the experience of previous people, those demons and sub-demons would often stay at the entrance, waiting for monks or lost animals to come in. ”

The three of them walked down the tunnel, and sure enough, they saw charred black corpses on the ground, all of which were small monsters.

Luo Feng observed with his spiritual sense, and found that the appearance of the monsters was not much different from that of animals, some of them only had some colorful magic patterns on the surface of their bodies, and some of them had an extra head, or they had horns that should have no horns, but they were very similar to the mutations mentioned before.

Tongtian Ancient Book looked down on the flesh and blood of these monsters, and explained reasonably: "Monsters are actually beasts with the blood of the demon race, in the primeval period, the demon race lived together with human beings on this land, and even now, there are often extraterritorial heavenly demons coming through the time and space tunnel.

The bloodline of the demon clan is very aggressive, it is difficult to eradicate, like the blood is absorbed by the grass and trees, the grass and trees become demon plants, and the cattle and sheep eat grass, they will be infected with the demonic energy, and the cattle and sheep are hunted by the tiger and leopard, then the tiger and leopard are infected again, and the corpse of the tiger and leopard is corrupted after death, and those maggots are infected again, and so on.

I think that those monks with demon spirit roots are the descendants of the demon bloodline, but human beings know how to use the method of cultivation to strengthen their own bloodline, so as to manipulate the demon blood for their own use, while beasts cannot practice, once the demon blood awakens, it will be manipulated in turn and become a monster.

Monsters are like monsters, if monsters can open Zhimeng, they can grow into demons, and monsters are the same, but the pure-blooded demons do not recognize them as the same race, and only disdainfully call them sub-demons. ”

Luo Feng listened to the explanation of the ancient book of Tongtian, while walking in the underground world, different from the kind of narrow mole pit imagined, the underground world is extremely spacious, five zhang high, the width is different in length, only one zhang in the short time, you must be careful to pass guò, more than thirty zhang in the long time, you can let the horse gallop freely.

The underground world is not dark, there is a substance called glow powder on the wall, emitting a little light, like the stars at night, with such a faint light, ordinary people may find it difficult to see, but for the monk, even if he can't see his fingers, it has no effect in the slightest.

The three of them walked unhindered in the underground world, this is the first layer of the Fire House Demon Hell, most of them are first-order demons, and occasionally second-order demons will come out, but with the slight aura emitted by Tu Bailing, these demons can leave with each other, after all, their instincts are much more sensitive than ordinary animals.

Tu Bailing held a map in his hand, hand-drawn by other monks who had explored the Fire Mansion Demon Hell, and was available in Xiuzhenfang City, with the danger zone and the location of the entrance to the next floor.

In fact, the location of the entrance to the passage will change, not always in the same location, but the cycle is very long, at least in five years, so as long as the map comes out in a relatively recent time, then the reliability is relatively large.

However, after a period of left and right turns, the three suddenly found that there was no road ahead!

Luo Feng asked, "Senior Sister Tu, what's going on?"

Tu Bailing said in a little panic: "It's okay, don't worry, please believe me, it's just a small mistake, it's definitely not the first time I've shown people the way and can't understand the map, even a child can read such a simple thing as Tu Suoji, how could a dignified monk not understand it?"

Luo Feng, who didn't even need reasoning, knew the truth of the facts, and tried his best to organize the language that did not stimulate the other party: "That, in fact, this kind of thing doesn't have to be forced, and finding the way according to the map is not as simple as imagined, everyone has things that they are good at and what they are not good at, just let me ......"

Tu Bailing jumped up like a cat with its tail stepped on: "No, no, no, don't you believe me? Do you think that a monk of the Five Realms will not be able to recognize the road when there is a map? My father said that even lions doze off, and I was just a ...... just now."

She glanced at the map in her hand, and suddenly her eyes opened, as if she had found a hidden secret book, and a look of surprise and joy appeared on her face at the same time: "I see, I took the map down! No wonder I always feel that the previous fork seems to have been reversed, and the problem of daring is here!"

Luo Feng covered his forehead and was speechless.

Huang Quan stepped forward silently, grabbed the map, glanced at it, and then turned around and walked back firmly.

"Wait, give me another chance, I promise I won't get lost again! My father said that as long as you are human, you will inevitably make mistakes, and the most important thing is to ......change your mistakes."

Tu Bailing was entangled unrelentingly, but Huang Quan only turned four forks in the road before he saw a passage extending downward.

......

When the three of them dived towards the second layer of the Fire Mansion Demon Hell, at the entrance of the Demon Hell, three more figures descended, two of which were An Lianhai and Yao Lianrong.

Yao Lianrong held a mirror in her hand, and after sparing it in place, the smooth mirror surface seemed to be thrown into the surface of a lake with stones, rippling one after another, and finally a moving picture appeared, which happened to be the scene of Luo Feng and the three of them entering the Fire Mansion Demon Hell.
