Li Nan immediately sneaked into Taiyin Valley without hesitation.
The entire Taiyin Valley is almost entirely surrounded by natural dangers. Many natural restrictions exist, and relying on the spiritual veins here, they are still very active even in the past hundreds of thousands of years.
If those restrictions are accidentally encountered, the Yuanying Yuanshen may fall, and even the true immortals will have a headache if they encounter them.
There are many restrictions here that were originally used by Scarlet Immortal Palace to block Lianxu. You can imagine how powerful they are.
Even if most of them are destroyed, just the tip of the iceberg that remains cannot be easily resisted by Nascent Soul.
Li Nan relied on his extremely strong spiritual consciousness to enter the Taiyin Valley without triggering the restrictions outside.
Taiyin Valley is very big, and the map inside has long since disappeared, or even never existed at all!
After all, the Red Immortal Palace used this place as its residence, so how could it be possible to spread the map? Isn't it the same as telling others how many things you have in your home?
Li Nan came here this time just to understand the terrain here.
After entering the Taiyin Valley, I immediately felt the howling wind around me, and the spiritual energy around me was very strong, but no monk dared to practice here because it was also accompanied by the strong Yin energy.
If the two qi of yin and yang can be balanced, then it will be a rare place of origin in the world.
But it is impossible to have both lunar and sun in one place!
Unless an immortal who masters the laws of yin and yang comes forward and uses great magical powers to force the fusion.
Such a place can probably only exist in the fairy world.
It is probably impossible for any human holy land in Yuanyang Realm to have such an area.
If the yang energy is strong, the monk's magic power will be violent and he can easily become possessed!
If the Yin Qi is strong, it will erode the monk's foundation. If you practice here, it will accelerate this process.
Only some people who practice Yin attribute skills can use a small amount of Yin Qi, but if they stay here for a long time, their immortal body will still be eroded.
In a short time, Li Nan went five hundred miles deep, and the spiritual energy around him began to become more and more intense, even comparable to the sixth level spiritual energy.
During this period, he encountered too many restrictions, even the remnants of the war.
There is a big hole dozens of feet long, and even if the spiritual consciousness is not strong enough, it cannot be discovered.
There will even be some space fluctuations from time to time. The war back then was too fierce, and the space here was a little unstable.
Just like what Feng Ming said, there is almost no grass growing here, and the ground is all yellowed soil. No matter how much spiritual energy is nourished, there is no way for life to be born.
Only things that need to absorb a large amount of Yin-type spiritual energy can grow here.
He encountered a few elixirs, but they were very toxic and could not be used normally.
As he continued to go deeper, he did not feel the breath of living things.
There are even some special hidden restrictions that he can trigger accidentally.
Then there was a game of games. Relying on his ability to destroy everything, he ran rampant and went thousands of miles deep in the blink of an eye.
And this is still only at the outermost edge.
He didn't dare to run too fast. If he accidentally hit a space crack, he would have to pay for his life.
He doesn't have the strength to resist the space cracks yet, and his immortal body in the Tribulation Realm is simply not enough to support the power of space!
Perhaps after refining the void, ordinary space cracks can survive.
One day passed, and he only walked less than 30,000 miles, because while walking, he wanted to test whether the All Worlds Spirit Bracelet could contact the mother formation.
The space cracks that appear from time to time here do have a certain impact. After all, he is using the power of space.
However, space cracks do not always exist. As long as you do not encounter space cracks along the way, there will be no problem.
Li Nan tried many times, and finally even tried it specifically near the space crack, and achieved a lot of success.
I was only blocked two or three times.
Not even a one percent chance.
Li Nan has no way to repair the space here now. If he wants to stabilize the space cracks and return to normal, he needs to inject the power of space and the power of various laws. At the lowest level, he has to refine himself.
The reason why those in the Yuanyang Realm didn't do it was probably because they felt that the gains outweighed the losses.
What if we can restore Taiyin Valley to normal?
It's just a ninth-level spiritual vessel.
In the Yuanyang Realm, those who can cultivate to the point of refining the void will basically have their own dojo, and ninth-level spiritual veins are the standard configuration.
The Great Wilderness Territory is so remote and has few resources, so even Lianxu wouldn't hesitate to stay here.
If you want to find a few fellow Taoists of the same realm to exchange experiences and trade some resources, you will have to travel for thousands of years.
There are several ninth-level spiritual veins in the entire Southern Wilderness, but the output of ninth-level heavenly materials and earthly treasures is very limited!
The reason is that the growth time of ninth-level heavenly materials and earthly treasures is too long.
The accompanying treasures of the ninth level spiritual veins often take 100,000 years to grow. Even for the realm of refining the void, which has a lifespan of at least 300,000 to 400,000 years, it is still a drop in the bucket.
Although the war between the two clans has temporarily subsided due to various reasons, Li Nan is still worried that Tong Sheng and Zong Nu will stay in Taiyin Valley.
A head-on collision would be very troublesome.
For half a month, he stayed in the Taiyin Valley without leaving. He even tried to refine a large amount of yin energy, but he didn't feel much discomfort. It was all absorbed and refined by his body.
Moreover, he discovered that the Yin Qi here is not unavoidable. If a ninth-level formation can be arranged to directly isolate the Yin Qi from the outside world and absorb all the Yin Qi in the formation, then it will be possible to create an area suitable for normal
The area where monks live.
However, it is very difficult. Even the most basic ninth-level formation cannot be arranged by everyone.
Those refining voids would be impossible to arrange unless they were masters of formations.
Then there are the materials related to the ninth-level formation, which are definitely a sky-high price!
If Li Nan wanted to set up a larger ninth-level formation, he would have to use at least five or six ninth-level spiritual trees!
He really doesn’t have this thing!
But he has an eighth-level spirit tree!
The last time a saint was born, the Immortal Realm has been upgraded to a level comparable to the Immortal Realm. In theory, it will be able to accommodate higher-grade spiritual veins in the future, but the conditions are not there yet.
He used the Spiritual Eye Tree to cultivate dozens of spiritual veins within the Immortal Realm. The highest grade one is currently only at the fourth level.
It can be forcibly upgraded, but the cost is relatively high. In addition, there are now true source fruit trees that provide spiritual energy, so there is no urgent need in this regard.
I definitely have to wait until I get richer in the future.
To upgrade the spiritual veins from the seventh level to the eighth level, I am afraid that 30 million spiritual crystals will be used. To the ninth level... it is not just as simple as spiritual crystals, but also requires some original treasures.
Anyway, Li Nan doesn't have such financial resources now.
In the immortality world, some elixirs have benefited. The elixirs that originally had an upper limit of only six levels have broken through their own bottlenecks and evolved to seven levels.
Some of the eighth-level ones originally seemed to possess some ninth-level charm.
For example, the Five Elements Divine Tree seems to have become more powerful. Although the grade has not reached the ninth level, it can at least reach the eighth level. The subsequent Five Elements Divine Fruit will definitely have stronger effects.
The True Source Fruit Tree was originally only a ninth-grade low-grade tree at most, but as the Immortality Realm upgraded its grade twice, it has enjoyed the benefits, and now it is already a ninth-grade high-grade tree.
Even those branches, which were originally only seventh-level high-grade ones, have now broken through the grade and almost look like eighth-order mid-grade ones.
Using those true source fruit trees as materials to set up a ninth-level formation would be no problem.
Anyway, there were more branches at the beginning just to feed the spiritual beasts and to let them awaken their bloodline quickly.
And it's not just the True Source Fruit Tree, there are also many seventh-level spiritual trees that seem to have broken through to the eighth level. The Immortality Realm has a radius of thousands of miles. How can you find hundreds of such spiritual trees.
Only the psychic treasure tree is a bit special. Li Nan doesn't know how to control it so far. Feng Ming does know how to produce results, but he doesn't know how to cultivate it.
Now, he has gone nearly ten thousand miles deep, and after mastering some of the rules inside, he speeded up.
At this time, the concentration of spiritual energy here is close to the level of eighth-level spiritual veins.
In fact, Li Nan's needs can be met here, but he wants to find a better place.
At this location, it is possible for ordinary immortals to break in!
Another month has passed...
Then, Li Nan ran out in disgrace.
Because he was in danger!
There is actually a group of Yin beasts living in Taiyin Valley!
It was originally a monster, but it has been corroded by Yin Qi all year round and has died.
However, the body changed and formed something like a zombie.
There is no breath of life, but the strength is very powerful, comparable to the early stage of Tribulation!
And there are at least a dozen of them!
Li Nan's God-Destroying Finger is useless against this thing, because this guy has no consciousness at all.
With just his strength, after working hard for several days and nights, he found that he was almost surrounded by Yin beasts, so he decisively escaped in embarrassment!
There is Yin Qi there. Even if I fight for ten thousand years, the Yin beast will not die, but I will not die!
After he came out, he sorted out the map he had explored this time and marked the place where he encountered the Yin Beast. The next time he went in, he would not take that direction.
He just wants a place to stay, but he doesn't want to risk his life with the things inside!
Anyway, it's impossible for all of them to be filled with these things, otherwise they would have been cleaned up by children and young girls.
After half a month of editing and confirming the map of the explored area, he began to explore the Taiyin Valley for the second time!
Entering from the other direction, we deviated from the position of about a thousand miles from the first time. After gaining experience, the speed was much faster. It took only five days for the second time to directly penetrate 10 million miles.
Compared with the hundreds of millions of miles he can fly in a day at full speed, this speed is very slow.
When he got here, he began to become cautious because he was likely to encounter the Yin Beast again.
In this dead silent place, everything is full of terror.
Moreover, Yin Qi can also affect spiritual consciousness, which will be greatly reduced, seriously affecting Li Nan's perception.
After exploring about five million miles further, Li Nan finally encountered a huge bare mountain!
Here, the spiritual energy level has reached the eighth-level mid-level!
Moreover, the restrictions around this mountain are extremely powerful. There are powerful restrictions almost everywhere. If a true immortal wants to go up the mountain, he must shed at least one layer of his skin!
This location is very good and suits Li Nan's wishes very well.
He bypassed the restrictions here and went up the mountain.
Then I discovered that the Lord was already here!
A late eighth-level Yin beast!
And after entering, he was discovered. Li Nan was crushed by this guy in all directions, and his spiritual attacks were useless. After only two moves, he was at a disadvantage!
He had to use the Immortality Pearl to hide his figure, and then quietly evade.
Good guy, there are so many difficult characters in Taiyin Valley?
Li Nan didn't go out this time, he just detoured in one direction, then went around for thousands of miles, and went deeper inside again!
Encountering these dangers is not a bad thing, at least it can prove one thing, that is, whether it is the human race or the demon race, unless you are at the Void Refining level, don't even think about entering it easily.
How many Void Refiners are there in total between the human race and the demon race?
Besides, everyone is injured now, and they won’t have the energy to come to Taiyin Valley in a few hundred years.
And after hundreds of years, I shouldn’t be afraid of them anymore!
In this way, Li Nan learned more and more about Taiyin Valley. Half a year later, he came to a spiritual mountain!
This spiritual mountain is also bare, but its spiritual energy level has reached the ninth level of low-grade!
After such a long time, he visited almost most of the places in Taiyin Valley. The details were definitely not in place, mainly a few high-grade spiritual mountains.
Almost all the spiritual mountains have Yin beasts on them, but this one has none inside!
In the entire Taiyin Valley, there are two ninth-level spiritual veins, both of which are low-level ninth-level ones. There is another ninth-level spiritual vein, which contains three Yin beasts that are comparable to the late-stage Tribulation. He dare not go there.
As for this spiritual mountain, he suspected that it was the place where Tong Sheng Jingnu had stayed before, and he killed the Yin Beast here.
Otherwise, there is no reason why all the eighth-level spiritual mountains are occupied, but not the ninth-level spiritual mountains.
However, it happened to be convenient for him!
He will set up a large formation in this spiritual mountain to allow Thunder Crocodile to break through, which will also facilitate Lin Zhiqing's breakthrough in the future, and will also allow Feng Ming and others to practice.
So, he left Taiyin Valley again, because setting up the ninth-level formation required a lot of materials. He did have enough eighth-level spiritual trees in his hand, but he still lacked many auxiliary formation materials.
Basically, they are all six and seven levels, and some are eight levels.
As for the time it would take to set up the formation, he wasn't sure. If Feng Ming and the others could help, they might be able to complete it within ten years.
A ninth-level formation costs more than 10 million spiritual crystals. Li Nan has an eighth-level spiritual tree in his hand, which can be regarded as saving a lot of money. Even so, I am afraid it will cost two million spiritual crystals!
After all, an eighth-level spiritual tree is worth at least hundreds of thousands of spiritual crystals, and he has to use fifty or sixty of them this time!
After leaving Taiyin Valley, he rushed to Qingtian Fairy City and began to collect the required materials on the way.
It took three months to get all the way down!
When he returned to the cave, he immediately told Feng Ming about the information he had inquired about, and then explained the large formation he was going to set up. He even had to ask Lin Zhiqing to temporarily interrupt her training to take charge of the affairs of the Wanjie Chamber of Commerce.
And he and Feng Ming started frantically refining the eighth-level formation flag and formation eyes.
The purpose is to explore Taiyin Valley three times as soon as possible!
