Extreme Comprehension Genius

Lin Feng and Bifei Yin flew to the west. After a stick of incense, they flew more than a hundred miles and arrived at a very special place in the snow-capped mountains.

It was a large basin in the mountains, surrounded by iceberg slopes in all directions, without any obvious exit. The basin was quite large, with a diameter of fifty miles, and the bottom was between one thousand and fifteen hundred meters away from the top of the surrounding slopes.

high.

The most surprising thing is that this basin turns out to be a nearly perfect circle!

It looks very much like the legendary crater made by a meteorite after it fell. It has this round shape. However, there have never been any flying rocks from the sky in the ice fields of the Cambrian Plane, let alone such large meteorites.

Possibility of round pits.

At this time, it was already evening, but the sun was still hanging slanting on the hillside, revealing half of a red circle and not completely setting.

The ice and snow in the entire basin reflects the sunlight and emits a colorful, bright light, which is not dark at all.

Bifei Yin said: "This is the largest basin in the Bailong Snow Mountain. Although there are no hot springs and the climate is cold, if the formation can be used to isolate the cold air from the outside, this should be a more suitable location. But this place

The spiritual energy of heaven and earth is thinner than outside, so it is only suitable for mortals to live in, and is not suitable as a sect's residence."

"Yeah." Lin Feng nodded.

The large basin with a diameter of fifty miles is indeed a very suitable place. If the temperature is suitable, it can be more than enough to house 200,000 people.

And he also noticed that the spiritual energy here was indeed a little thin, obviously not as good as other places in the Bailong Snow Mountain. Lin Feng thought that maybe the surrounding mountains outside blocked the spiritual energy from entering, so he didn't think much about it.

"It would be very difficult to change the environment here in one night, and time is very tight. What are Mr. Lin's plans?"

"That's what I thought... Well, I need your help."

Lin Feng expressed his idea, and Bi Feiyin did not express any objection. The two of them did not waste any more time and immediately started to set up the formation. They did not call anyone else, because with this level of immortal formation, others basically helped.

It’s not a big deal, only the two of them are capable of doing it.

The formation is actually very simple, just two steps:

The first step is to use a formation to isolate the air flow to create a hemispherical invisible air wall to surround the entire basin. With the surrounding mountains blocking the basin itself, plus the barrier of the invisible air wall, it is enough to block the cold air outside, making this place

become a stable area.

The second step is to cover this with a barrier that refracts light. Under its coverage, the entire basin is like a greenhouse. Sunlight can come in, but heat cannot be easily dissipated.

As long as these two steps are completed, this large basin can be turned into a large greenhouse!

The two people flew to the center of the basin and floated in the air. Each of them was responsible for a part and cooperated to complete the formation.

Each hand and technique was played out, and each rune flew to the hillside more than 20 miles away, imprinted on the ice surface of the hillside. Some vague power fluctuations appeared on the periphery.

They directly use magic techniques to change that area from a long distance to form an "eye of formation". This method is undoubtedly much faster than people going to the scene by themselves and setting up "eyes of formation" one by one. However, this method requires

With such great strength, Lin Feng could only achieve this level of formation after reaching the Golden Immortal Realm!

As soon as Lin Feng took action, Bi Feiyin was a little surprised and praised: "Congratulations, Mr. Lin, your cultivation level has improved significantly."

"Haha, if you praise me again, I will be ashamed of myself."

The sun quickly set, and the sky gradually dimmed. But the countless runes played by the two people shone brightly, illuminating the entire basin, making it still as bright as day.

An invisible air wall surrounding the entire basin and covering all the places above gradually formed.

Close to the invisible air wall is another almost transparent protective barrier that glows faintly, like a light mask, covering the entire basin.

Lin Feng felt that the energy in his body was rapidly draining, and he had to replenish some elixir before he could continue. On the other hand, Bi Feiyin was as calm and relaxed as if nothing had happened. Even though her strength had weakened, she was still at the level of Luotian.

Time passed unconsciously...

With Bi Feiyin's help, it was naturally much faster than Lin Feng alone, and the "greenhouse" isolating the basin was finally completed. After the formation was completed, they no longer played spells, and the bright runes also dimmed.

The light in the basin suddenly disappeared and returned to the pitch-black night.

However, there was some glimmer of light on the horizon. The night had passed, and it was almost morning.

When the work was about to end, Lin Feng felt the aura of heaven and earth here again, and still felt a little strange.

Generally speaking, most valleys will cause the concentration of "qi" due to terrain problems. All kinds of qi are similar. For example, in valleys facing the sun, yang qi will gather, making it appear particularly warm and beneficial to the people living there.

It is very beneficial to people's health; shady valleys will gather Yin Qi

, not suitable for living, and prone to breed some evil things related to ghosts and monsters. The spiritual energy of heaven and earth in this world of cultivation is almost the same. The concentration in the valley is often higher than in other places. Whether it is the back mountain of the Xuanwu Mountains, or

The hot spring valley of Bailong Snow Mountain all conforms to this characteristic.

But the basin in front of us is an exception!

Originally, in order to find a place to accommodate everyone, Lin Feng could not pursue perfection and not care about the aura problem for the time being. Now that the "big greenhouse" is completed, Lin Feng's mentality of pursuing perfection has returned. The aura here is weak, and it is really...

A very regrettable thing.

He suddenly said: "Fein, don't you think it's strange?"

"What's wrong?"

"The aura of heaven and earth in Bailong Snow Mountain is very strong, not to mention those hot spring valleys. Every hot spring valley is a good place. Even the aura of other places in the snow mountain is very strong, but in this basin, there is only such a thin aura of heaven and earth.

, even compared to Canlan Continent. This is not normal! Logically speaking, in this closed basin, the spiritual energy will not be lost, and it should be richer than outside."

Bifei Yin said: "It is true that the spiritual energy of heaven and earth in this basin is significantly weaker than that in the outer areas. The master has also thought about the reason and mentioned that there may be something under this basin that absorbs a large amount of energy.

Caused by the aura of heaven and earth.”

"Has your master investigated it? Do you think it is something under the basin that has absorbed a large amount of spiritual energy from heaven and earth?"

Bifei Yin said: "This is just a possibility. The teacher only mentioned it briefly, but did not delve into it. Because the White Dragon Snow Mountain Hot Spring Valley is more than enough for us people, we did not use this basin.

Keep it in mind."

"I'll go down and take a look."

Since Mu Wenxin, the owner of Lan Cixuan, had made this judgment about the aura of the basin, Lin Feng also took it seriously and flew to the bottom of the basin.

A thick layer of snow has accumulated at the bottom of the basin, and then it slowly transitions to a layer of hard and cold ice. I don’t know how many years these snow and ice have accumulated, and there is no clear boundary between them.

Lin Feng closed his eyes and felt it carefully.

The surrounding spiritual energy of heaven and earth is very thin and flows naturally and slowly. Moreover, the spiritual energy of heaven and earth is penetrating under the ice at a very weak and slow speed. It is very slow. If you are not paying attention, you will not notice it. Although this process is very slow.

, but if it continues for many years, it will cause the spiritual energy in the entire basin to become very thin.

"Sure enough, there really is something down there..."

Lin Feng immediately made a decision. He flew into the air again and took out the divine sword Potian. In an instant, the divine sword turned into a two-handed giant sword again, longer than a person's length, exuding a terrifying momentum.

Bi Feiyin was startled, staring closely at the sword in his hand, hesitated for a moment, and asked: "Mr. Lin? Is this... the divine sword Potian of Emperor Kangning?"

Lin Feng smiled and said: "Fei Yin has great eyesight, just like the divine sword that breaks the sky."

Bi Feiyin's eyes were full of surprise, but she didn't ask any more questions. She wisely chose not to pry into Lin Feng's private affairs. Lin Feng had absolute trust in her and was not worried that she would reveal the secret of the Excalibur, so it was very difficult for her to ask any questions.

Don't worry and show the divine sword in front of her.

He held the sword in both hands and slashed towards the bottom of the basin!

The energy of the body poured into the divine sword crazily, and at the same time activated the power of the divine sword itself. A long sword light appeared from the tip of the sword, reaching several kilometers in length!

The sword light passed through the middle of the basin, instantly creating a crack several kilometers long in the ice and snow.

The snow was forced open by this huge force, and snowflakes were flying all over the sky.

"Kakaka..."

The extremely hard ice layer under the snow made a cracking sound. The cracks gradually expanded to both sides. Soon, a huge ice crack was several kilometers long, a hundred meters deep, and ten meters wide at its widest point.

Appear at the bottom of the basin!

Bifei Yin looked a little lost in thought and praised: "The power of the divine sword is indeed extraordinary."

Lin Feng quickly rushed toward the crack and reached the bottom.

A hundred meters deep at the bottom of the basin, it was all covered with ice and snow, and it did not even touch the real ground. What Lin Feng was looking for to absorb the spiritual energy of heaven and earth did not appear in this crack. However, this crack

The concentration of the spiritual energy of heaven and earth at the bottom is significantly higher than that above the ice surface!

Bifei Yin also flew down quickly and came to the bottom of the crack to look around suspiciously.

She whispered: "There is indeed something there, this spiritual energy..."

Lin Feng thought for a moment, grabbed the two-handed giant sword in his hand, and stabbed it into the ice underneath. Then the two-handed giant sword, together with his whole body, quickly spun. Like the tip of a well, it quickly pierced the ice.

Drill down. The deeper you drill down, the more obvious you can feel the spiritual energy of the world next to you.

These spiritual energy of heaven and earth actually penetrated deep into the ice layer, but they were not completely absorbed and disappeared by anything, but accumulated.

"Crack!" Lin Feng suddenly drilled into something.

There was a special sound and a stagnant feeling coming from the tip of the sword, which was like drilling into a piece of wood...
