After Wu Feng penetrated deep into the spiritual vein, the process of exploration was slower, but he harvested more spiritual objects. In about eight or nine days, Wu Feng noticed the spiritual ore veins, and the spiritual energy began to thicken into qi veins, and the spiritual objects were densely distributed into belts.

The spiritual vein is divided into many kinds, first of all, it is necessary to count the qi vein, mainly for the flow of aura, which is divided into upper, middle and lower grades according to the quality, and the better qi vein, as well as the dragon vein.

In addition to the qi veins, it is necessary to count all kinds of spiritual ore veins, and the spiritual energy in the qi veins gathers to form various spiritual ore deposits, including spiritual jade ore, and different kinds of spiritual ore ores. According to the qi vein period, the level of the spiritual vein is different, and after condensing into the ore vein, the grade and reserve of the spiritual object are naturally different.

However, after the qi veins condense into ore veins, not all the aura disappears, and according to the previous underground veins, it is also possible to maintain contact and even maintain the flow of aura. But in any case, the underground where the spiritual veins of zài are stored is more abundant than the spiritual energy in the rest of the ground.

Previously, in the peripheral vein section, the spiritual objects were relatively sparse and low-level, and Wu Feng also collected the spiritual objects inside.

And now, seeing the huge and rich reserves in the spiritual veins, Wu Feng will not give up the spiritual veins, and will appear on the ground for less time, and continue to explore deeply along the spiritual veins and collect the spiritual objects in the spiritual veins.

"Up to now, I have mainly dug up fourth-level spiritual objects, and a small number of third-level spiritual objects, and occasionally dug fifth-level spiritual objects, which have basically remained at the intermediate level. However, the spiritual objects of the spiritual ore veins show a trend of in-depth growth, as long as this trend is maintained, after going deeper for a while, it is very likely to dig up high-grade spiritual objects, and there may even be top-level spiritual objects......" Wu Feng thought to himself, seeing that the spiritual ore veins were getting better and better, Wu Feng became expectant.

However, Wu Feng was also thinking: "According to the information provided by the fifth-order lion beast on the Hundred Beast Mountain, the Hundred Beast Mountain is roughly sixty thousand miles long. It is 36,000 miles wide, and it enters from the wide side and goes deep along the length to the center. ”

"In the Hundred Beast Mountain, within a radius of six thousand miles from the center, it is the middle section of the mountain range, and there are three seventh-order demon beasts. With nearly a hundred sixth-order demon beasts. ”

"You enter from the wide, go deep along the length, and after about 20,000 miles, you may enter the middle belt. Before entering the spiritual ore vein, the ground exploration is about five or six thousand miles, although the process of digging spiritual objects underground is much slower, but after these eight or nine days, it is also 15,000 or 6,000 miles. The overall process is more than 20,000 miles, and it will soon enter the middle belt......" Wu Feng secretly analyzed.

"However, this middle belt also has a radius of six thousand miles, and the entire area is relatively large, and a hundred demon beasts are scattered, which is also relatively sparse, and there is no threat to it. And the Hundred Beasts Mountain in the middle section is inside the entire mountain range. The most resourceful section should not be missed to collect. ”

"But now dig up the veins of spiritual objects. The spiritual objects in it are more abundant, and they cannot be directly discarded. Dig up spiritual objects in the ground, and you won't alarm the demon beasts on the ground, so you simply dig the spiritual objects to the end, and then kill them from the ground to the ground, and then you may go deep into the middle zone. Kill from the center to the periphery. Wu Feng thought to himself, and after making a decision in his heart, he quickly dug up the spiritual object.

"Sixth-level spiritual object!" Two days later, when Wu Feng was digging according to the spiritual vein, he inadvertently probed into the distance. Unexpectedly, he found a sixth-level spiritual object, and he immediately became excited.

In this spiritual vein, digging a sixth-level spiritual object for the first time, for Wu Feng's harvest, it is by no means more than a sixth-level spiritual object, and it proves that his guess is correct, the spiritual object reserves of this spiritual vein show an increasing trend, can you dig out the first sixth-level spiritual object, are you still worried that you can't dig the second one?

Sure enough, Wu Feng found a second sixth-level spiritual object about sixty miles away, and the fifth-level spiritual objects in this section were obviously denser than before.

However, after two days of advancement, Wu Feng affirmed that he had entered the underground of the middle section of the Hundred Beast Mountain.

The appearance of spiritual objects was more dense, and the process of Wu Feng's excavation was slower, but the harvest was quite gratifying, and a large number of spiritual objects entered his storage ring. Except for the fifth- and sixth-level spiritual objects, for the rest of the middle- and low-level spiritual objects, Wu Feng did not calculate the number at all, and he did not know the specific harvest.

But after digging up the sixth-level spiritual objects, and after another five days, Wu Feng dug up a total of sixty-three sixth-level spiritual objects, two hundred and ten fifth-level spiritual objects, and an average of twelve sixth-level spiritual objects were dug every day, such a huge harvest was absolutely incomparable.

In fact, from the time he entered the Taixu Space to the present, especially in this section of the Hundred Beast Mountain, Wu Feng alone has harvested more materials than some trial disciples.

If there is only one special storage ring, it is likely that after a while, the storage ring will be full, after all, the monster materials collected take up quite a lot of storage space.

But Wufeng has a three-yuan bead space, and there are a lot of storage rings in it, and a large number of materials can be privately hidden, so it is natural to search directly, and it can be privately owned by himself, so it is more motivating to search.

"Huh?" Another day passed, and when Wu Feng probed forward again after digging for a while, he not only frowned, but his heart was full of surprise.

In the section between fifty and ninety miles ahead of him, there is no more existence of spiritual objects, and it is unknown ninety miles away, but the probability of spiritual objects appearing is very small.

However, in the section of fifty to ninety miles that can be explored, although there are no zài spiritual veins, the qi veins have become more concentrated, and they can be called high-grade medium-sized spiritual veins.

There was an unexpected situation in the spiritual vein, Wu Feng accelerated the excavation of the spiritual object fifty miles in front of him, and then fled forward to explore, forty miles away, Wu Feng explored fifty miles again, and saw the end of this section of spiritual vein.

However, this end is only relative to the previous paragraph, and it is not the end of the real spiritual vein.

And at this end, from the other two directions, two spiritual veins converged, but these two spiritual veins are qi veins, and there are no zài spiritual ore veins.

After these three spiritual veins converged, they turned directly to the ground......

"The spiritual veins are mainly earth attributes, mixed with water and wood attributes, which may be due to the two connected spiritual veins. The three spiritual veins of earth, water, and wood gather, with the heaviness of the soil, the flexibility of the water, the vitality of the wood, the fierceness of the fireless, and the sharpness of the gold, which can just be fused together......" Wu Feng thought to himself, his heart was full of doubts, and some speculations were faintly born.

After a general exploration, Wu Feng did not hesitate, and probed to the ground along the three intersecting spiritual veins.

"The aura of these spiritual veins, as if it is being pulled by some kind of traction, is gathering to a certain point......"

"These spiritual veins and spiritual qi actually have a tendency to transform into liquid?"

"These spiritual veins and spiritual qi are actually half liquid and half qi?" With the different situations detected, Wu Feng's heart was even more surprised, but he bathed in the spiritual veins, which was quite comfortable, and he was soon completely recovered.

"If you cultivate here, you are likely to make great progress!" Wu Feng thought to himself, but he was full of doubts in his heart, naturally he would not stay underground to cultivate, not to mention that in the Taixu Space, all kinds of cultivation materials were abundant, and it would be a complete waste to use exploration time to cultivate.

"Hmm, what is that?" Suddenly, a layer of hard earth and stone appeared in front of the spirit vein, and inside the layer of earth and stone, there was a special metal object, but due to the limitation of distance, Wu Feng could only see a little, and could not recognize the whole picture.

"It turned out to be a sword, a big sword that was nine zhang long, eight feet wide, and three inches thick!" When Wu Feng probed the metal object, he suddenly became surprised, such a large sword body, except for the sword-shaped flying spirit weapon, basically would not appear.

But the big sword in this stone layer does not exist in the state of being in charge of the main control, and it is completely displayed for the ontology, so it is naturally strange to reach such a size!

Wu Feng carefully probed the big sword, only to see that the big sword was erected in the soil and stone layer, the tip of the sword was facing the depths of the ground, and the hilt was facing the ground. Outside the rock layer, there was a pool, and according to Wu Feng's exploration, the pool was in a cave.

However, what surprised Wu Feng even more was that the pool outside the rock layer was not an ordinary accumulation of water, but a liquid formed by spiritual qi, that is, the three spiritual veins underground, and the three spiritual veins of earth, water, and wood gathered together and accumulated into a pool of liquid.

"Could it be that this is the Hundred Beast Mountain Sacred Spring?" Wu Feng thought to himself, thinking that this could be very big.

"The spiritual energy in the cave is very mixed, and the spiritual liquid in the spiritual spring is mixed with three spiritual qis, which is not suitable for a single attribute cultivation. But from the spiritual spring outward, the three spiritual qi gradually separated, and they were in the same direction as the underground spiritual veins, and the three demon kings who came to the Hundred Beast Mountain happened to have the same three attributes, and staying outside for some cultivation was better than cultivating in the spirit pool!" Wu Feng thought to himself.

In the previous time, from the fifth-order lion beasts, he learned that the three seventh-order demon beasts of the Hundred Beast Mountain did not cultivate in the holy spring, but separated the two sides of the holy spring, and now seeing the situation of the spiritual spring, Wu Feng naturally understood the reason.

For the same reason, Wu Feng was even more sure that the spirit pool outside the spirit vein was the holy spring of the Hundred Beast Mountain.

"It was speculated that the Taixu Sword Order may have been stored near the Holy Spring, although it was only speculation and there was no strong corroboration, but since we found the location of the Holy Spring, we must investigate it!" Wu Feng thought to himself.

However, when Wu Feng came up with this idea, he unconsciously released his soul thoughts and probed the nine-zhang sword in a targeted manner.

"Taixu? Could it be that this is the Taixu Sword Order?" Wu Feng was in the Jiuzhang big sword, close to the sword body of the hilt, and saw the inscription of the word Taixu, and couldn't help but guess like this.

"But it's impossible! The Taixu Sword Order is a sword order, it should be relatively small to be normal, and this sword reaches nine zhang, which can be called a big sword that exceeds the specifications. And in the Taixu space, where the ruins of the Taixu Gate are located, it is normal to have a spirit sword engraved with the word Taixu......" After guessing, Wu Feng thought of the unreasonableness, and also doubted his guess.

"However, under this spiritual pool holy spring, there are no other discoveries, not to mention the rest of the sword-shaped objects, and even no refining artifacts, there are no signs of human activity, and they are completely earth, stones, and spiritual energy...... although they are suspicious and speculative, they also can't find any evidence of suspicion, and the size and specifications of the sword body can't explain the situation.

"In any case, from the relationship between this big sword and the spirit pool, it can be seen that the big sword strengthens the gathering of spiritual liquid, and if this great sword is collected, the spiritual liquid gathering will slow down, and even return to the ground and disappear. ”

"However, this is in the void space, I don't know when it will be opened later, and the aura returns to the underground to keep the spiritual veins flowing, which is not necessarily a bad thing......"

"Since this is the case, then collect the big sword first, and then cultivate in the spirit pool. The spirit pool with mixed three attributes, for people and demon beasts with single attributes, it is necessary to clear the mixed attributes, but they can completely absorb it, although they have less gold and fire twin spirits, but they can operate the holy vein transformation, and it is completely a holy land for cultivation, second only to the land of five spirits!" Wu Feng thought to himself, and made a decision in his heart. (To be continued......)
