The use of refining void fire qi can strengthen the quality of the finished spiritual weapon and even improve the rank, which has always been a very important part of the strength of the monk.

In this way, one can imagine how popular the refining of Void Fire Qi must be......

Refining Void Fire Qi can be said to be another important purpose for Li Yu to enter the Fire Refining Dao this time, and the promotion of seeking immortals to ascend may fall on this Refining Void Fire Qi!

"Stop!"

The two monks guarding the Hell Mansion blocked the halberd in their hands, and Li Yu immediately felt a breath of gunsmoke coming to his face~~

What a murderous aura!

Hurriedly took out the fire refining order, and the two guards carefully checked it to make sure that there was no problem, and then casually took it away.

Then each played a set of tricks, and suddenly ...... Hell is open!

"Gege ......"

The large iron gate of dozens of zhang slowly opened, dragging a sound like rust, and the inside of the Fire Refining Mansion was no different from the crater of the volcano as far as Li Yu looked at~~

What's even more bizarre is that Li Yu actually hallucinated at this moment, as if the open Hell Mansion suddenly turned into a huge python head, and pounced on it with a "zi" sound.

The hallucination was only for a moment, but Li Yu felt unusually real, and the sweat on his forehead flowed down unconsciously......

"Hurry up, remember to come out after March, otherwise you will be at your own risk!"

Li Yu nodded and said that he knew, the Fire Refining Dao was relatively special, full of all kinds of mysterious spiritual power, and three months was already the limit of an ordinary Dao Foundation monk, beyond this time, even if he didn't need to be forced by the sect, the monk might fall here forever!

I forgot to say it, the Fire Refining Dao is one of the few places in Jidu Gate where life and death need to be conceited~~

Stepping in slowly, the passage was very long and glowed with bursts of strange red light, Li Yu was surprised.

Because there was no unexpected sense of spatial transformation, that is to say, it is very likely that this fire refining path exists in the true realm and inside the Jidu Immortal Gate......

Li Yu was puzzled, how could there be such a strange existence inside the Jidu Immortal Gate?

Just as Li Yu was puzzled, the person had already walked out of the long passage, and the real situation inside the Fire Refining Dao was basically the same as what he had discovered!

Barren, desolate, dead and silent......

The Fire Refining Dao is simply an upgraded version of the Guangzhen Immortal Relic Battlefield, and this place makes people extremely depressed for no reason, no wonder it is difficult for ordinary people to stay for three months~~

Looking at the cracked and solidified scorched earth, and looking at the desolate stone forests on all sides, Li Yu was on guard against incursive incursions.

"Woo woo~~"

A whimpering wind blew the hair on Li Yu's forehead, and even the wind was warm here......

"Click, chirp~~"

A strange sound suddenly came from the ground, Li Yu hurriedly stared at the not far below his feet, and then saw that the ground under his feet quickly cracked a crack, and then a touch of sky-blue fireworks shook his body and quickly rose into the air.

It was a flame, and Li Yu was beside him, but he didn't feel any temperature.

And at the moment when the flames were raised, Li Yu felt that something in himself had been taken away, and his originally depressed and gloomy mood seemed to usher in a dawn that cleared the clouds and saw the sun~~

Li Yu immediately knew that this was the Heart Refining Dao Fire!

This fire didn't hurt their Jidu disciples, but it didn't help them, but for the Xiao Ghost clan, there was only complete damage left.

Watching the flames rise and then gradually disappear, Li Yu didn't track or look at it because this fire was nourished by his emotions, and it would take at least a few years to turn into refining Void Fire Qi, and even if he didn't get any nourishment, it would take six or seven days to transform a Heart Refining Dao Fire into Refining Void Fire Qi.

And this ...... It's not that Li Yu can afford to wait!

Walking aimlessly all the way, Li Yu lowered his head and kept thinking~~

Just as Fang Cai's Heart Refining Dao Fire jumped up from the ground and soared into the air, Li Yu felt the altar in the dantian throb, and then a faint devouring thought came out.

This is easy to understand, because it is the instinct that comes from the fire in the palm of the hand to devour all fires.

But in addition, there was something in Li Yu's sea of knowledge that jumped......

It's the mysterious point of light that has been silent for a long time!

This point of light has occupied a corner of Li Yu's sea for a long time, and it is hidden deep on weekdays, but when the Heart Refining Dao Fire appeared, this point of light was quite excited to flick ~~

Li Yu looked like he was just walking with his head down, but in fact, most of his consciousness was deep in the sea of knowledge, monitoring and even testing the point of light.

However, nothing was found.

It seems that Fang Cai's moment is just an illusion, no matter how Li Yu teases, this point of light is not moving at all!

This also made Li Yu's face gloomy and abnormal, and it was really an extremely troublesome thing to be occupied by these inexplicable things~~

Knowing that the matter of the light point change might still need the help of the Heart Refining Dao Fire, Li Yu had to put it down for the time being and began to act more quickly.

There are nine layers in the Fire Refining Dao, the first to third layers of inner disciples can compete with the ghosts, the fourth to sixth layers need true disciples to deal with it, and the seventh to ninth layers need to dispatch elder-level figures to be able to sit down......

Xiao ghosts are also like the clans of the human race, there are strong and weak and the weak absolutely obey the strong, some act alone, and some are in groups, in short, you can see Xiao ghosts as a smaller social circle.

That's right, that's it!

According to Li Yu's current strength, he had just reached the peak of the first-order Dao base, and he had not even reached the second-order Dao base, and the first layer was his limit.

However, the space of the first layer was vigorously swept by the Jidu Immortal Gate, not only were there not many ghosts left, but even the speed of rebirth of ghosts became extremely slow~~

Therefore, this place is basically equivalent to Li Yu's back garden, and you can stroll around at will.

As for whether it will be besieged by Xiao ghosts?

If such a thing really happens, then it is estimated that Li Yu can wake up laughing in his dreams.

This is also the reason why Li Yu made a plan at the beginning, Lei Yuan kept it for his own use, and refined the Void Fire Qi to sell it......

At this time, it can be seen that Li Yu has accumulated a lot of reserve knowledge of use, and ordinary people can only try their luck when they encounter such a situation.

However, Li Yu came up with a series of ways to lure Xiao ghosts based on his understanding of the characteristics of Xiao ghosts and the special topography and environment of the Fire Refining Dao, which is to rush to experiment one by one~~

The first method Li Yu wanted to use was to find a place where the yin qi was strong and the dead qi was thick, and set up a 'Six Societies Ghost Ding Delusion Array'!

These six societies of ghosts and ghosts can accumulate and brew to transform the power of the gloomy and evil fall in a place into the body of the six ghosts, these six ghosts are poisonous to others, and their power is enough to deceive most people in the world into demons, it is an incomparably terrifying formation.

Once this kind of formation is put into an ordinary mortal city, I am afraid that a day and a night's work can make the people of a city turn into a beast that has lost its independent sanity, and only know that it is driven by the will of the earth demon in the underworld, and it is extreme and unreasonable~~

It took a lot of effort for Li Yu to start with such an evil formation, and he was even monitored for a long time......

However, everything has good and bad sides, for the human race, it is a poison that pierces the intestines, but for the ghost of Xiao, it is very likely to be the supreme delicacy, the peerless treasure pill!

Of course, this is just a guess by Li Yu.

And now Li Yu is verifying his guess......

It may not be easy to find a place where the yin qi is strong and the death qi is thick in other places, but in the fire refining path, there were really too many Xiao ghosts that were exterminated back then, and the yin and death qi was stagnant, this kind of place was too common, and even gave Li Yu room to pick and choose!

After finding a place that he thought was suitable, Li Yu began to take out the Six Societies Ghost Ding Nonsense Array and combine it with the terrain.

In just a few moments, Li Yu completed this process, and then all he had to do was wait~~

This time, Li Yu really didn't have much time to delay, so the scheduled time was one day!

If the day's and night's kung fu has not attracted Xiao Ghost, then Li Yu will have to change the next method......

But fortunately, or maybe Li Yu's method was really effective, so it didn't take long for him to attract the arrival of a ghost.

This also made Li Yu very happy, and finally didn't have to waste time experimenting~~

As rumored, the ghost is unusually fierce, as if it was born without such fear, and its brain is usually not smart......

In the distance, the Xiao Ghost roared and rushed over, his eyes full of greedy thoughts for the gloomy and evil aura of the gathering place in the Six Societies Ghost Formation, and he didn't think that this might be a trap at all!

"Hmmm~~"

In the eager and malicious roar, Xiao Ghost directly ignored Li Yu, who was hiding on the side, and directly threw himself into the Six Societies Ghost Ding Lie Array.

Slowly walking out of the shadows, Li Yu's face was a little weird~~

Li Yu obviously felt a cold gaze just now, and there was no doubt that the ghost had discovered him.

But Ghost Xiao completely ignored him, and instead went straight to the Six Societies Ghost Ding Lie Array.

Li Yu didn't expect that the sanity of this ghost was even lower than the rumored one, knowing that this was a bureau, and the first thing to pay attention to was "food".

Li Yu is even beginning to wonder now, is this kind of thing that can be suppressed by instinct really still clearly exists sanity?

did not disturb the ghost to eat, because if Li Yuruo made a move at this time, it was very likely that he would be affected by the ghost Ding of the Six Societies and the nonsense array, and this array would not recognize the lord~~

also took advantage of this opportunity to take a good look at the ghost Xiao!

From the aesthetic point of view of human beings, the ghost should be considered ugly, with two horns on its head, a green complexion, and a similar appearance to the human race, but it has an extra toe on both hands and feet, and there are countless notches on the face surrounding the shape of a six-toed giant claw......
