Since Lin Fei entered the state of retreat and cultivation, it had only been a little more than a day, and the forbidden formation he had arranged had almost no concealed effect.

The pillar of fiery red light that rose into the sky was at least a hundred zhang high, making it easy to see within a radius of several miles. Moreover, after gathering too much fire spirit energy, it can have a gathering effect, and soon more and more fire spirits will converge here.

These low-level fire spirits have no spiritual intelligence, they only know how to converge towards the place where the fire spiritual energy is most vigorous, even if they are surrounded by a layer of pale red light, obviously guarded by a formation, these fire spirits also seem to be unaware, like moths to a fire.

The forbidden formation laid by Lin Fei conceals the killing array, and it is extremely lethal to the fire spirit, as long as the fire spirit touches the formation prohibition, it is like the fire spirit energy is instantly absorbed by the formation, and it is directly refined into a fire crystal.

It can be said that from the beginning of Lin Fei's retreat to the present, there have been hundreds of fire spirits that have been extinguished by the formation, and in a moment, around the formation set up by Lin Fei, a circle of fire crystals has fallen, and the red light is shining and looks extremely brilliant.

A single fire spar is not valuable, but hundreds of fire spars are piled together, which is not low, and even cultivators in the foundation building period will be tempted.

Hunting fire spirits is not a difficult task, but the difficulty is that they can find so many fire spirits, so although there are many cultivators who have entered the trial of the Flame Hell, there are very few who can harvest hundreds of fire crystals at a time.

You must know that four hundred fire crystals are almost worth a spirit stone, if you can earn a spirit stone in one trial, this fire hell will not be crowded?

The current situation is very strange, the fiery red pillar of light rises to the sky, surrounded by a layer of pale red light, and there are hundreds of fire crystals scattered around the periphery, I am afraid that whoever sees this scene in their eyes will think that there is a strange treasure born here, right?

Lin Fei's original purpose was not to alarm anyone and practice in retreat alone, but he really didn't expect that it would be such a big disturbance in just an extremely ordinary retreat.

Now it has only attracted some fire spirits to come over, but as time goes by, more and more cultivators will definitely discover the abnormalities here, and even if it doesn't alarm the entire Flame Hell, it is enough to cause a sensation!

After Lin Fei had been in retreat for a full day and a half, a cultivator finally appeared in the depths of the canyon.

This is a cultivator in the early stage of foundation building, dressed very similarly to Ma Zhiyuan, a typical "backpacker", and the most common trialist in the Flame Hell.

Originally, this cultivator had just encountered a fire spirit and was going to kill it, but who knew that this fire spirit ignored him completely, and instead rushed in the opposite direction.

Fire spirits will only act on instinct, and after discovering cultivators, they often pounce on them without hesitation, when did they become like this?

In addition to being curious, this cultivator naturally chased after the fire spirit, and soon found a fire light rising from the canyon, and his heart immediately beat wildly, wondering if he had come to run from time to time and made an extremely incredible discovery?

After entering the depths of the canyon, this cultivator saw with his own eyes that the fire spirit he was targeting was directly refined into a fire crystal after hitting a dark red light shield. Moreover, around this dark red light mask, there were at least hundreds of fire crystals falling, which looked really exciting.

However, compared to the pillar of fiery red light that rose into the sky, what were these fire crystals?

Doesn't such an astonishing wave of psionic energy mean that an extremely incredible treasure is about to come out?

The cultivator immediately began to wonder, what benefit could he gain after this astonishing discovery?

Such an astonishing anomaly, if there really is a supreme treasure, its quality is only beyond one's imagination, right? And such a treasure, is it really capable of being possessed by oneself?

The fire spirit was refined at the touch of a button, which shows that the current prohibition is not simple, and it is not easy to break most of it. However, if you don't want to find a way to seek the treasure in the ban, can you just be satisfied with picking up the fire crystals around you?

The current movement is really not small, and if it is delayed for a long time, I am afraid that I will find that there will be more and more cultivators here, and how can I still have my own share when the time comes?

As soon as he thought of this, this cultivator turned his heart sideways, planning to try to forcibly break the ban, if he could break the ban, wouldn't he have a chance to get the treasure in his hands?

With such thoughts, this cultivator no longer suffered from gains and losses, but directly raised a flying sword and slashed towards the red light shield that shrouded several zhang squares!

This cultivator is not a great person, but the flying sword magic weapon used is refined by the Shushan Sword Sect, one of the eight major sects in the Kunlun Realm.

The Shushan Sword Sect has always been known as the first sword sect in the world, and the flying sword produced by the Shushan Sword Sect is the guarantee of quality, and the stocks of the Shushan Sword Sect are naturally the weighted stocks among the weighted stocks. In particular, the attack section index in the large market section of the stock market is based on the stocks of the Shushan Sword Sect as the leading stocks, and it can be said that the rise and fall of the stocks of the Shushan Sword Sect will affect the rise and fall of the entire attack section!

The flying swords produced by the Shushan Sword Sect are also high and low, for the use of the really strong, they are basically customized flying swords, and they will definitely not circulate in the market, only those mass-produced flying swords are the continuous source of wealth of the Shushan Sword Sect.

The flying sword used by this cultivator at the moment is the Qingfeng-type mass-produced flying sword produced by the Shushan Sword Sect!

Don't underestimate the Qingfeng Flying Sword because of mass production, because this model of the flying sword is made of the Qingshuang Sword, one of the two great swords of the Shushan Sword School, although it has a significant weakening in power, and the materials are not the same, but the victory lies in the stable structure, which can continuously attack and output, it can be said that it is a cost-effective flying sword magic weapon, once it is launched, it will be sold for a long time, and it is a popular product in the flying sword market!

The forbidden formation refined by Lin Fei can be regarded as a good means, but the formation materials he uses belong to the high-value goods, no matter how exquisite the formation is, if it has a hard battle with the Qingfeng Flying Sword, the honorary product of the Shushan Sword Sect, it will inevitably fall behind.

A Qingfeng Flying Sword is worth three spirit stones, to say the least, and how much did Lin Fei spend on the materials used to arrange the formation? It was only more than a thousand Kunlun coins, and not all of them were used to set up the formation!

As a result, as the Qingfeng Flying Sword continuously attacked on the light shield formed by the forbidden formation, the entire light mask began to sway, as if it could be shattered at any time!
