The cave is a natural sign of fire that leaks out and burns the ordinary sand. The walls of the cave were solidified by the burning, and they became even harder, making it difficult for the soul to probe......

When he advanced the cave, Wu Feng probed the cave wall, but the scope of the exploration was too small, and he didn't notice the special situation, so he kept moving inside, and didn't care about the condition of the cave wall.

Now that the cave is a mixed vein of earth and fire, it is natural to strengthen exploration, not only to explore the depths, but also to explore the cave wall, perhaps in the sand of the cave wall, there is a spiritual ore derived from the vein.

Wu Feng had such a thought, slowed down his advancing speed, and probed the cave walls on both sides. However, the sand on the cave wall was solidified, and the soul thoughts were released hundreds of zhang, and I didn't notice the special situation, let alone explore the spirit mine.

"Such a dense and dense spirit element, coupled with the solidification of sand and soil, there must be a spirit mineral, the current location of the cave wall, there is no sign of minerals, when it is at the edge of the vein, then it is necessary to explore deeper. Wu Feng thought to himself, keeping the probe and moving forward.

At this time, due to the fire and earth spirit elements, the density of the head-on impact was not as hot as the fire spirit elements. In fact, just like a flame, the outer flame is hotter than the burning inner flame, and in this fire spirit mine, the spirit element is scorching on the outside, and the inside is back to normal.

"Hey, there was a fork in the road...... Wu Feng moved forward again, and he didn't measure how far he had advanced, and he suddenly noticed that in front of him, there were two caves in the cave, not a single one before.

Facing the two cave paths, it was really difficult for Wu Feng to choose directly, so he could only release his soul thoughts along the cave and explore deeper. Fortunately, along the cave road, there is no obstruction of the cave wall, although the cave wall is curved, it can also be explored, even if the curved section is removed. The interval of straight line exploration is also farther than that of cave wall exploration.

"There really is a spiritual mine!" first probed into a cave, and soon noticed the spiritual ore in it, which immediately surprised Wu Feng.

"Hey, it's the loess crystal ......" noticed the spirit mine, so he naturally had to explore it carefully. Quickly recognizing the category of spirit ore, Wu Feng felt sorry for a while, and thought to himself: "It's a pity that it's loess crystal, a common earth spirit refining material, not too precious things. ”

"The cave is getting smaller, and about six hundred zhang forward, loess crystals appear, and the deeper depth cannot be measured. Wu Feng thought to himself, there was a surprise. There are also regrets.

However, Wu Feng did not go directly into the cave to explore and dig, and withdrew his soul thoughts to explore another cave. This cave is full of strong fire spirit elements, and the cave is wider, and Wu Feng explores inward to a depth of eight hundred zhang, and also discovers the spirit mine.

"It's Fire Spirit Sand...... It's a pity, it's a pity!" with the previous cave. The idea of detecting the spirit ore is the same, and there are surprises. There are also regrets.

Fire Spirit Sand, although not as common as Loess Crystal, but the demand is also smaller, the demand for the two spirit ores is comparable, and neither of them is a precious treasure.

Fire Spirit Sand, in some Fire Spirit Vessels. Can be doped a little. And this is not the main use, the fire spirit sand is mainly used to open the light and refine the spiritual weapon, the final pass of the refining tool, and the auxiliary object for refining the edge.

Two common types of minerals. The initial surprise slowly dissipated, and Wu Feng thought of the Flame Scorpion, and said to himself: "The evolution of the Flame Scorpion, relying solely on the earth and fire spirit elements, may not be able to promote evolution. I didn't notice anything special in this cave......"

"Scorpion-like beasts and insects like to eat some sand, if the fire scorpion swallows some fire spirit sand, there is a possibility of evolution. Wu Feng had a flash of inspiration and guessed the possibility of evolution of the Flame Scorpion.

However, guessing such a situation, Wu Feng was even more disappointed, if this guess was true, it would prove that there were no special effects in the cave.

"The current situation and inference, the only special thing about this cave is that the fire spirit element is too rich, and the fire and earth spirit elements were mixed before, so I guessed that there might be spiritual objects such as spirit jade in the cave. ”

"The situation that has been explored, whether it is loess crystal or fire spirit sand, there is no such a rich spirit element, if this place is not scattered spirit vein, it should have a spirit jade thing. If this is a scattered spirit vein, in the process of formation, it can only be empty and happy......" Wu Feng secretly speculated.

Immediately adjusted his mentality, and thought indifferently: "I am fortunate to have gained, but I have no chance to lose, and I am indifferent." The current situation can only deepen the exploration, the mine cave of the fire spirit sand, the fire spirit element is more dense, let's explore this side first!"

I am fortunate to have gained, but I have lost my life. Wu Feng is a person who does not accept his fate, even if he loses it once, it is just a loss! This is Wu Feng's idea, and his mentality has been sublimated unintentionally.

In the ensuing exploration, it was indeed not found that the spiritual jade was found, and it was confirmed that it was a scattered spiritual vein, but the loess crystal and the fire spirit sand contained a huge amount. However, these two types of spiritual objects are not among the treasures, and they have a large amount of benefits, but for individuals, they are not the slightest benefit.

After all, digging out a small amount of spirit ore is not of much use at all. However, if you really want to dig in full force, the investment is not proportional to the harvest, unless you hire someone to mine, it is also full of trouble.

All kinds of thoughts flashed, but fortunately, Wu Feng's mentality was sublimated, and he kept his thoughts indifferent, and he didn't care about the gains and losses.

Maintaining an indifferent state of mind, Wu Feng's thoughts were even more profound, and he thought secretly: "This mixed spirit ore has two different main ore veins, and according to the exploration situation, it is a medium-sized ore vein, and it contains greater value. ”

"This vein has no direct benefit to itself, mainly because it is weak and cannot be fully mined. However, this vein does not have to be taken out to realize its specific value, and if you trade with someone who has the strength to mine it, you can also sell it for a good price if you have the exact condition of this vein. Wu Feng thought to himself.

The main thing is to break through the Tiangang Realm, the amount of materials needed is greater, the demand for spiritual objects is greater, and the two cultivations after the breakthrough, the refining acupoints are all refined one by one, and the amount of spiritual objects needed can be seen.

In other words, in the ordinary Tiangang Realm, the spiritual objects that need to be refined, and the cultivation materials that are needed are a huge amount. And the Wufeng Five Spiritual Initiates are five times the needs of ordinary people, plus the needs of refining the body, the actual need for spiritual objects and materials is basically eight times that of ordinary people.

Wu Feng is an alchemist, he can make alchemy to earn materials, there is no mistake in alchemy, and all of them are guaranteed to become Dan, and the profits are very large. However, the more advanced the elixir, the more advanced the herbs needed, it is difficult to gather enough refining spirit grass, the opportunity for alchemy is less, and the space for profit is also smaller.

The technique of drawing symbols will also face such a situation.

Moreover, some spiritual objects and materials are often hard to find, and if you want to trade with the holder, you have to come up with a larger trade object. Trading out of necessity is a matter of necessity, and there is no guarantee of true fairness.

Wu Feng's calculations at this time are planning for the future, which shows that his plans are far-reaching, rather than just caring about the short-sighted people in front of him.

With such thoughts, Wu Feng investigated again, this time the investigation was more careful and comprehensive, and the situation of the investigation was carefully recorded.

After all, Wu Feng's strength is weak, and in the face of the potential to mine spiritual ore, he will inevitably not be able to bring people here directly. That will only force the other party to kill and seize the treasure.

Of course, even if Wu Feng wants to trade, he will also find trustworthy people and power, and will not trade blindly like that.

After drawing the general structure diagram, Wu Feng didn't prepare to dig it, and went directly out, ready to remember the location outside, so he let go of the spiritual mine first.

Wu Feng came to the mouth of the cave, and according to his usual cautious approach, he did not directly escape from the soil, but first released his soul thoughts to explore the situation on the surface of the sand.

"Hmm, anyone?" However, the results of the investigation suddenly made Wu Feng startled.

Then he probed carefully, and suddenly said in surprise: "It is a disciple of the Sword Sect, the leader of the Earth Yuan Realm, a large group of Spirit Martial Realm, a formation of about more than 100 people......"

The Sword Sect, one of the three major sects in the Southern Regions.

The three major sects in the Southern Regions, the Sword Sect, the Burning Sun Sect, and the Royal Beast Mountain, are all listed among the top ten sects of Dongxuan.

Although Wu Feng had never been to the Southern Regions, let alone had direct contact with the Sword Sect, he could also identify the costumes and symbols by paying attention to the ten major sects of Dongxuan, coupled with the gathering outside the Jingang Secret Territory.

Recognizing the identity of the disciples of the Sword Sect, Wu Feng's heart was full of doubts, there were more than a hundred disciples of the Sword Sect, and there were more than a dozen of the leading Earth Yuan Realm, and the rest were all in the Spirit Martial Realm. Such a team is by no means a formation to fight, at most it is just a trial.

However, it is such a camp, and the current move is very strange, which makes Wu Feng even more puzzled.

"Some of these Sword Sect disciples are responsible for building dwellings and using condensation talismans to create sturdy caves. Some people are holding discs in their hands and looking around carefully, what is going on?"

"The disciple of the Sword Sect, the disciple of the Spirit Martial Realm as the main force, entering the middle of this Flame Spirit Desert is already an unusual thing, and looking at this strange practice, it is unusual...... Could it be that these Sword Sect disciples are here for the spirit ore underground? The reason why the Spirit Martial Realm was sent was just to cover up the target and avoid the target being too big and exposed?"

"Could it be that the thing of the disc is the legendary soul seeking disk? I can perceive the underground cave, but it is my own powerful soul thought, and if the rest of the people come, at least the same Tiangang realm, maybe I can detect the underground cave......"

"However, the Yanling Desert is so huge, and it happens to be in this position to explore the Tiangang Realm underground, which does require some coincidences and chances. What's more, even if you accidentally detect the underground cave, but you don't have the target of the fire scorpion, and you don't have the convenience of directly escaping, no one will decisively deepen the exploration. ”

Guessing the intention of the disciples of the Sword Sect, and then thinking about the relevant situation, he finally locked on the disciples of the Sword Sect, and the disc he was holding when he investigated, and firmly believed in his heart: "That disc should be a spirit search plate, and the exploration of the disciples of the Sword Sect may not be to detect clues, but only to do a rough investigation according to the distribution of spirit elements." ”

Coming to such a conclusion, Wu Feng slowly reassured, waiting with peace of mind, observing the actions of the disciples of the Sword Sect, and at the same time thinking about his own whereabouts...... (To be continued......)
