Extreme Comprehension Genius

Yu Lingyuan was left to sit in the main hall, while Lin Feng and Duan Tianya left the main hall.

Lin Feng followed Duan Tianya to the center of Haitian Island, which is also the highest mountain on Haitian Island. At the foot of one of the mountains, there is a cave that goes deep into the mountain. Not long after entering, the cave bifurcated, and it looked like it was dug manually.

The mine they came out of. After walking into one of the bifurcated caves, it soon turned straight down, like a vertical mine, leading all the way to the ground. They fell vertically in this mine and kept falling.

I have traveled tens of thousands of meters and still haven’t reached the end.

Lin Feng couldn't help but marvel, Haitian Island is indeed quite famous.

Duan Tianya said as he fell: "There is a Xuanjing mine underground here. Because it is also the core area of ​​Haitian Island, in order to prevent damage, we did not mine it on a large scale, but only collected a small amount. In the past, during the mining of Xuanjing mine, we

I found that there seemed to be a very strong spiritual energy underground, so I kept digging downwards. It was not until I dug three hundred miles underground that I discovered the reason. There was a very strong underground spiritual energy, which happened to pass through here."

"It's amazing enough." Lin Feng praised.

A depth of one hundred and fifty kilometers is equivalent to digging through the entire Haitian Island and digging into the underground layer. The rock layer on Xuanlu is much harder than that of Canlan Continent. A depth of one hundred and fifty kilometers has been dug out.

The difficulty of the mine may be more difficult than digging a thousand kilometers in Canlan Continent.

Duan Tianya looked a little regretful and said: "It's just too deep and it's not convenient."

The two people fell straight down, and after a while, they finally reached the bottom.

A cave that is not very big has been dug out of the ground, but it is still spacious, just like the expanded mine tunnels under some mines. Although it has gone deep into the ground, it is not dark at all, but is very bright. The surrounding areas

There are shiny particles everywhere on the rock wall. These particles are natural black crystals. They emit bright light and illuminate the entire underground cave.

This place is also quite hot, with the temperature reaching at least a hundred degrees. But for a master in the Luotian realm, this temperature doesn't matter at all.

Compared with the brightness and high temperature here, what caught Lin Feng's attention more was the aura here.

Lin Feng has noticed that the concentration of spiritual energy here is very strong, and it has obvious fluidity. Although the entire underground cave is closed and surrounded by rock walls, the spiritual energy is still flowing. They are continuously flowing from one side of the rock wall.

It overflowed and kept drilling into the other side of the rock wall.

This is because the black crystals themselves have a strong ability to absorb and release spiritual energy. They are like conductors of spiritual energy. The spiritual energy of heaven and earth realizes the "flow" process through the rock wall through the action of the black crystals in the rock layer.

.This process is like electric current flowing through metal.

"It is indeed a good place." Lin Feng nodded.

He is completely convinced that this is indeed a spiritual vein. This level of spiritual energy flow can only be explained by underground spiritual veins, and it is also a very strong underground spiritual vein! These black crystal mines are just a companion product of the spiritual veins.

That’s all.

Although the Xuanjing Mine is also very valuable, it is nothing compared to the spiritual veins. Because having this spiritual vein means almost inexhaustible spiritual energy!

The spiritual energy of heaven and earth itself is the energy source of the world of cultivation. Almost everything revolves around the spiritual energy of heaven and earth. Cultivation requires spiritual energy, maintaining the operation of formations requires spiritual energy, and the growth of various creatures requires spiritual energy, crystals, black crystals and other important minerals.

Need aura.

An underground spiritual vein extends in all directions. It connects the spiritual energy of a large area, far from the small area of ​​Haitian Island.

As long as this underground spiritual vein can be led up and supplied to the protective formation of Haitian Island, there is absolutely no need to worry about Ji Yuqing's war of attrition. No matter how many demons Ji Yuqing drives, it is impossible to exhaust this underground spiritual vein!

Duan Tianya added: "We originally planned to use this underground spiritual vein, but we failed to use it. Our 'Small Spirit Gathering Formation' cannot do this."

"Yeah." Lin Feng nodded again.

This is the flaw of the 'Zhou Tian Ling Gathering Small Formation'. After all, this formation is not large enough, and its effect in the horizontal direction is okay, but its ability in the vertical direction is weaker, and the vertical height of several thousand meters may not be a problem.

But at a depth of more than a hundred kilometers underground, the small spirit gathering array is somewhat incapable of doing what it can. It cannot gather the spiritual energy underground to the ground.

This flaw is usually not a big deal, but it is only in special circumstances like this that it becomes particularly obvious.

"Unless we can turn the entire Haitian Island upside down and expose the spiritual veins, then we can use it..." Duan Tianya's words were just a joke. That would not only destroy Haitian Island, but also

Just blow up another big hole.

Lin Feng laughed: "No, no, no need to bother. Come on, Lao Duan, we are ready to start work."

"Start work?" Duan Tianya was stunned for a moment, then came to his senses and asked doubtfully, "What? Do you think you have any idea, Alliance Leader?"

Lin Feng said: "Well, you are right here. First, set up a 'Small Spirit Gathering Array' to gather the spiritual energy in this place."

"Here? This is the spiritual vein. What's the use of setting up a formation here to gather the spiritual energy of heaven and earth?" Duan Tianya was confused.

"I'll take care of the rest." Lin Feng said nothing and flew upwards.

Lin Feng thought of an idea: "Aura Pump"!

Although the aura of heaven and earth is a very special energy that cannot be explained by common sense, it is consistent with the common points of all air flows: the side with higher concentration will flow to the side with lower concentration. Using this characteristic, you can completely combine the heaven and earth.

The spiritual energy draws up.

A small part of the spiritual energy of heaven and earth in this spiritual vein is overflowing outwards and replenishing it on Haitian Island. This natural process is relatively slow and the effect is not obvious. What Lin Feng needs to do now is to speed up its flow.

Lin Feng left the mine and came to the top of the mountain in the center of Haitian Island. After estimating the location of the underground cave, he chose the location.

Here, he will set up a formation: "Reverse Spirit Gathering Formation".

It has the opposite effect to the "Small Spirit Gathering Formation". This formation does not gather the spiritual energy of heaven and earth, but quickly dissipates the collected spiritual energy of heaven and earth outwards. This is a very partial formation, although it is not difficult.

It’s not too big, and it’s about the same difficulty as the “Small Spirit Gathering Formation”, but almost no one will use this. Everyone likes the strong spiritual energy of heaven and earth, so who would scatter the high-concentration spiritual energy of heaven and earth when they’re full and have nothing to do?

In fact, when Lin Feng first saw this formation, he thought that the person who invented it was just "full of food"...

But now, he finally understood that this formation actually had some use.

With Lin Feng's current ability, it is very simple to create a small "reverse spirit gathering array".

He directly took out the divine sword and swung it quickly. The sword light flew, and the surrounding rocks were cut quickly, and the gravel flew. On the rocks, deep or shallow scratches appeared. These scratches happened to form a unique talisman.

A large number of runes formed the main lines of the small spirit gathering array. Finally, Lin Feng used his fingering skills, pointing, and using his own energy to complete some details of the array.

That is, half an hour later, Lin Feng had completed the "Reverse Spirit Gathering Formation" at the highest point of Haitian Island.

After a while.

Duan Tianya also flew up from below and said respectfully: "Leader, my small spirit gathering array has been set up. However, what is the use of the small spirit gathering array under the ground? It cannot allow the spiritual energy of heaven and earth to reach the third level.

It’s hundreds of miles high on the ground.”

Lin Feng smiled and said: "Don't worry, don't worry."

Duan Tianya quickly noticed that the top of the mountain had been "processed" on a large scale by Lin Feng, and the surrounding terrain was a little different from before. A large number of runes formed a strange formation, filled with some strange fluctuations. And

In this area, the aura of heaven and earth is disappearing rapidly.

Duan Tianya wondered: "Strange, what's going on? It seems that the spiritual energy of heaven and earth here is being rapidly consumed? Leader, this is..."

"Hehe, you have a good eye, you have already discovered this. Don't be anxious, don't be anxious, you will know the result soon." Lin Feng said with a smile.

Lin Feng held the hilt of the Excalibur with both hands, and the sword tip was downward, hanging upside down. The Excalibur's light flickered, getting brighter and brighter. And Lin Feng's person also began to shine, seeming to merge with the sword light. It was obvious.

, strength is gathering.

Duan Tianya looked at him in surprise, even more puzzled. It seemed that Lin Feng was planning to use some powerful attack method. What was he going to do?

When the light reached its peak, Lin Feng suddenly thrust the divine sword toward the rock below!

"Dang!" The tip of the sword collided with the rock, making a crisp collision sound.

Immediately afterwards, the sword sank into the rock below. And the strong golden light on the sword quickly cut through the rock layer and penetrated downwards.

Lin Feng held the hilt of the sword tightly, maintaining the posture of stabbing at the rock.

The rock on the top of the mountain was shaking slightly, but it did not crack, nor did it explode. Only the place where the sword was pierced opened a hole, and a beam of light shone out.

After a while, Lin Feng finally pulled out his sword: "Okay."

On the top of the mountain where the sword was stabbed, a very deep hole with a diameter of about three feet has appeared. This hole directly pierced the entire rock layer on the top of the mountain and was connected to the cave at the foot of the mountain!

The cave below originally entered horizontally from the foot of the mountain, and then turned straight downwards inside the mountain, all the way to the ground. Now that the top of the mountain has been penetrated by the forest wind, it has formed a through-hole from the top to the bottom.

A deep, straight well underground.

Duan Tianya approached the entrance of the cave and took a look, and was shocked.

Except for this hole, the mountain has no cracks. Cutting a stable hole in such a hard rock is more difficult than breaking the rock. Lin Feng's move is no less difficult than directly destroying the top of the mountain.

"But why is this..." Duan Tianya was still puzzled.

"It'll be ready soon." Lin Feng smiled.
