In addition, there is one thing in common. The crystal mines like this are all very low-grade crystal mines, and their value is not high.

It's just these characteristics. The suddenness made Lin Fei have an idea. Could it be that the appearance of these evil spirits is only aimed at the higher crystal mines in Sanyecheng?

It is no wonder that Lin Fei would think this way. Valuable crystal mines like Yanhuo crystal mine actually have evil spirits, and lower-level crystal mines like Xuanhuo crystal mine.

Some crystal mines have yin evil spirits, while some crystal mines have no yin evil spirits. In the lower crystal mines, there is no yin evil spirits at all.

If you don’t see the trick, it’s really stupid.

"Have the three night city ever offended anyone?" Lin Fei asked Zhang Guanjia to ask.

Butler Zhang thought for a long time, and he didn't seem to offend anyone...

Oh, right……

Zhang Guanjia suddenly remembered that a famous person had really appeared in Three Nights City.

This person is still the one who has appeared.

At first, this man named Zhang Mo came to Three Nights City when he was attacked by Sea Star City. After the three night city was beaten down, Sea Star City retreated like this time.

So at that time Three Nights City had to find a new city owner, and this demon was the first monk who stood up and wanted to be a city owner.

It was just that the people who were fighting for the city master of the three nights were not only Zhang Mo, but also another monk. The two sides fought for a few days, and finally the city master made a high move and defeated Zhang Mo and took the city master. .

At that time, no matter whether it was City Lord or Zhang Mo, he was able to write his name on the Luoshen Monument, but Zhang Mo was defeated because he couldn't fight the city master.

Since then, Zhang Mo has disappeared in Three Nights City.

And in the fifth year after he left, there was more of this evil spirit inside the crystal mine of Sanye City, but Zhang Mo had not appeared in Sanye City since he left. Qi seems to have nothing to do with Zhang Mo.

"It doesn't matter. It's clearly hateful, and then revenge comes." After hearing this, Lin Fei finally heard a rough idea. It seems that the reason why the crystal mine here will appear evil is that This is a ghost called Zhang Mo.

If it is artificial, then all this can explain why only the crystal mine with the highest value will appear the evil spirit. This magic is clearly to limit the development of the three night city, so as to solve his hatred .

However, Lin Fei feels that this trick is extremely trivial.

If you have a grudge against the lord, then go to the lord and trouble. Why should you put the spearhead in the three night city? Let Sanye City develop so slowly in recent years...

But this is a very old thing. It's hard to say whether Zhang Mo is alive or not. Lin Fei doesn't want to care about Zhang Mo's affairs anymore. The most important thing before him is to leave Zhang Mo behind. The evil spirit is resolved.

As long as it is determined that this is man-made, then there must be a way of restraint. After all, no matter how concealed Zhang Mo does, there will be flaws left. No one can do everything tightly and without flaws.

In the next few days, Lin Fei has been walking around in the crystal mine, thinking about ways to deal with the evil spirit.

Now the Three Nights City is in desperate need of resource development. Although there is a threat from the Starfish City, the Three Nights City cannot always stop here. Instead, it needs to develop. In the current situation of sparse manpower, it can only rely on the city's own resources.

Therefore, Lin Fei must solve this problem, as long as the evil spirits are resolved, these crystal mines should be able to breed crystal mines immediately.

It's just that the evil spirits in the ground are really strange. They are endless. Even though Lin Fei constantly purifies the evil spirits in the ground, the evil spirits will still be produced one after another.

Often just cleaned up, but in a blink of an eye, the evil spirit will spread all over the ground again at a very fast speed, leaving Lin Fei helpless.

It seems that it is completely impossible to directly clean the evil spirits in the ground. The most direct way may be to find the source of the evil spirits, and then wipe out the evil spirits in the crystal mine. .

But where is this source, but it has never been found...

On this day, Lin Fei returned without success, walking in the Three Nights City, thinking about ways to solve the evil spirit, but at this time, Lin Fei suddenly saw that there were a group of children who were performing various Practice.

Like this monk who just entered the road, naturally there are not many real elements, it may have just been built, Lin Fei did not take them seriously, but Lin Fei suddenly saw that one of the children was actually in In his hand, a five-element array has evolved.

Although it is only the outline of the five-element array, it does not have much power, but Lin Fei also secretly lamented that the specifications of this small world are high. The same tricks are placed in the Luofu world. Perhaps only monks who have been practicing for several years, Only then can it be exhibited.

"Wait..." Feeling, suddenly, Lin Fei unexpectedly discovered that he saw the five-element array in the hand of the child, which was already in operation. The five-element array had no wind autobiography, but condensed in At this moment, the true elements of the core of the Five Elements Array suddenly flowed in all directions towards the Five Elements Array.

Soon, these five-element arrays radiated bursts of spiritual power.

It was just that when it was cast here, the child had a struggling expression on his face. It was too late to take out the five-element array completely, and a fault appeared along with the real element in the body.

His five-element array dispersed at once.

The child touched his head awkwardly and then left in a group of children's laughter.

Lin Fei kept looking at the child.

Specifically, Lin Fei is thinking about the five-element array that he just displayed.

After thinking for a long time, Lin Fei suddenly clapped his hands.

"No wonder I said why I can't always find the source of the evil spirit, the original reason is here..." Lin Fei said to himself, followed, and went back to look for Zhang Guanjia.

After finding Zhang Guanjia, Lin Fei asked Zhang Guanjia to ask for the distribution map of Sanyecheng Crystal Mine. After all, Crystal Mine is the most precious resource of Sanyecheng. Something like a distribution map is bound to exist.

Zhang Guanjia thought about it for a long time, and finally ran to the library, and found out the broken map for Lin Fei.

Lin Fei took a look at the distribution map, and finally found a most central position, and also went to the field to look at it. Sure enough, there is only one crystal mine that has been degraded for a long time. There are no crystals in it. The veins There is no aura.
