Because of the existence of the locking array, this side of the world must be closed and isolated from the world.

Su Chen couldn't easily open the formation, otherwise, the aura inside would escape and flow out in an instant.

In other words, he has to practice in this closed environment, in real retreat.

If you are an ordinary person, if you are in retreat for too long, you will probably go crazy.

However, Su Chen now has experience, his heart is stable, and there is no pressure on lifespan, so even if he retreats for dozens or hundreds of years, he will not have much impact.

Moreover, he has gained a lot this time, and there are still many things to do, and every day is full and busy.

When I was bored, I fell asleep, practiced the Great Dream Heart Sutra, entered the Dream Building, chatted with Begonia, sat and discussed, and occasionally could prostitute some advanced cultivation knowledge for nothing.

It's not lonely.

Soon, ten years passed.

Because of the nourishment of the aura of the thousand-year-old spirit bead, the corner where the Lock Spirit Array was located had become full of spiritual energy, and a lot of flowers and plants had grown, full of greenery and vitality, which was in stark contrast to the dead and silent valley outside the array.

Like an oasis in the desert.

These flowers and plants are not ordinary wildflowers and weeds.

Rather, it was a packet of elixir seeds that Su Chen obtained from the ruins of the Sifang Sect, called Yunling Grass, they were not elixirs, but they had other wonderful uses.

After nourishing and growing with the help of aura, it can absorb the elemental power of wind, rain, thunder and lightning in nature, and decompose weak aura through its own photosynthesis.

In the past, when the spiritual energy of the Sifang Sect was exhausted, it tried to improve the environment of the sect and increase the concentration of spiritual energy.

But it's a pity that there are a large number of ink snakes living underground in that Wind Thunder Valley, and they can't be killed at all, so in the end, the Sifang Sect still hasn't changed the situation of spiritual energy depletion.

Of course, Su Chen didn't expect these Spirit Grasses to be able to change the concentration of the aura in the entire region.

Cultivating these spiritual grasses, firstly, he felt that the retreat place was bare and awkward, and secondly, he also practiced the technique of cultivating spiritual plants, after all, he had unlimited longevity, and when he entered the immortal cultivation realm in the future, he could try to cultivate some precious elixirs by himself to prepare for future cultivation.

Of course.

Although the aura fed back by the spirit grass is small, it can add up to a lot, and it can also reduce the loss of spiritual energy, so that one's own blessed land can be maintained for a longer time.

In addition, in the past ten years, Su Chen has read the detailed explanation of the primary refining weapon countless times, and after repeated experiments and attempts, he finally succeeded in refining his first magic weapon.

He used the ink snake skin as the raw material, engraved the invisibility talisman, and incorporated the two small spells of "dust avoidance" and "colored light technique", and finally succeeded in refining a new black robe.

This robe is jet black all over, the surface is smooth like satin, before you look closely, there are python patterns intertwined, the aura flows, it is cold and comfortable to wear on the body, it can automatically fit the body shape, and cover a certain degree of divine detection.

The invisibility charm is activated, which can hide the body for a longer time, and the color light change can make the color of the robe change, making it easier to integrate into the surrounding environment, and the dust avoidance technique can make it dust-free, more clean and comfortable.

In general, this black robe, although the grade is not high, strictly speaking, it can only be regarded as a medium-grade magic weapon, but the practicality is very high.

Compared with some high-grade magic weapons with a single effect, it is not much better.

Dan, array, talisman, instrument.

The so-called four arts of cultivating immortals, Su Chen can barely understand some of the fur now, not to mention proficient in the introduction, but at least they can be skillfully applied to the daily practice of cultivation.

These things cost him a lot of energy and time.

Because of the limited lifespan of ordinary people, there are few things to do, and they don't even have enough cultivation resources, so they naturally won't waste too much energy on this, even if they are immortal cultivators who specialize in these, they can only specialize in one at most, and there are very few people like Su Chen who dabble in everything.

Unless you have cultivated to an extremely high level and have lost the pressure of your lifespan for a short period of time, you will go back to cultivating these things at the same time.

And these skills will all become the capital for Su Chen's future survival in the immortal cultivation world.

In addition to these.

In terms of realm, Su Chen's improvement is very slow.

It was a full ten years, and with the help of the thousand-year-old spirit bead, coupled with the glow of the sun and the qi luck infusion of the Chu State, the three forces were superimposed, and they barely broke through the seventh layer of qi refining.

That's not to say how bad his qualifications are.

It's because although the Locking Spirit Array has a certain effect of preventing the flow of mana, it can't be completely eliminated, and every time the mana is raised by cultivation, two or three out of ten will eventually escape from the body.

This caused his cultivation speed to slow down a lot.

Fortunately, these escaping mana turned into aura again and did not pass.

And in this process, Su Chen unexpectedly discovered that the re-cultivation of mana after the passage of time seemed to have a purifying effect, making his realm more profound and his mana much stronger.

And so another decade passed.

Su Chen's cultivation was finally about to break through to the eighth layer of qi refining.

In this process, Su Chen carried out a long-distance dream, contacted Zhou Yi through the imprint of the divine soul, and learned the specific situation of Middle Earth and the Seven Xuanmen.

The so-called Middle-earth, to be precise, should be called Middle-earth.

If the whole world is regarded as a planet like the earth, then the southwest belongs to a small fragment of a broken continent.

There are many places like this, and you can walk in the middle of the endless sea.

Middle-earth, on the other hand, is located in the middle of the Endless Sea, the largest continent, and its area is more than 10,000 times wider than that of the southwest.

Here, there is also the mundane world, where countless countries are lined up, kingdoms are in contention, and there are many family gates.

But the immortal cultivator is the master of everything.

The replacement of ordinary dynasties, in a word, most of the countries are in the hands of those immortal cultivators, or they are subordinate to those immortal cultivators, and they pay tribute every year, becoming a tool for immortal cultivators to rule the mundane and loot wealth and resources.

For example, the Qixuanmen where Zhou Yi is now located.

Under his command, he ruled over seven or eight large and small kingdoms, and the territory was vast, and the scale was comparable to that of the entire southwest.

This made Su Chen quite emotional.

The world of cultivating immortals is really the law of the jungle, as long as the strength is enough, even if it is a dynasty and a country, it must bow its head, the so-called Emperor of Heaven, in the face of absolute strength, he also wants to change it, and he will kill if he wants to, to put it bluntly, he is just a housekeeper who helps the sect manage the world.

"One Qixuanmen can rule so many countries, what kind of luck does this have?"

Su Chen was a little envious.

If he can control several countries in Middle-earth in the future, the speed of cultivation of the Dragon Sutra will definitely be faster.

Legend has it that before Middle-earth, there was a super dynasty, as long as the strength was strong enough to suppress other immortal cultivation sects, at that time, the immortal cultivation sect would become a vassal of the dynasty.

If you can establish a strong and huge immortal cultivation dynasty in Middle-earth and suppress all the immortal cultivation sects, how terrifying will the strength of the dynasty's luck be?

"Ahem, forget it. These things are too far away from me. Reform and change and other things are too troublesome and too dangerous to suit me. However, at least for now, the overall environment of Middle-earth is still very good, full of spiritual energy, and the land is vast and rich, and it is indeed a better place to practice than the Southwest. ”

Su Chen secretly thought to himself.

After determining the situation in Middle-earth, he was also reassured.

In the next time, as long as you concentrate on cultivation, increase your strength, and wait until the next time Penglai Immortal Island is reopened.

……

There is no time for the cultivation in the mountains.

Soon another forty years passed.

this day.

In the lifeless valley, the wind and thunder were stirring, and a loud bang came, and the golden light was vented, and the surrounding dead air was immediately cleansed.

One after another, the immortal spirit qi spread out from the center of the valley, and the green and verdant spirit grass spread out like a tide.

Su Chen's figure fluttered and broke out of the formation.

He was dressed in a black robe, his long hair hung down from his shoulders, and his face was handsome and flowing, and sixty years passed without leaving any trace on him.

Even because of the growth and improvement of his cultivation, his skin looked more smooth and crystalline, and he looked a little younger.

The mana gauze condensed all over the body, blooming with golden light, rendering the black robe even more gorgeous.

Nine layers of qi refining!

It took Su Chen a long time to digest almost all of the power contained in the thousand-year-old spirit bead, and with the help of the kingdom's luck and the power of the sun's radiance, coupled with the inventory of pills on his body, he finally broke through to the realm of the ninth layer of qi refining.

In fact, when he was in his twenty-eighth year, he had already refined the eighth layer of qi.

However, with the improvement of cultivation, more and more mana passed away, and even the Locking Spirit Array could not be completely avoided, and in the end, it took more than thirty years to break through the realm.

It is precisely because of this long time of tempering that his mana is pure and vigorous, far stronger than that of monks in the same realm.

It's not just mana.

Su Chen's idea of the Great Sun Concept has finally reached the level of perfection, and he can really try to visualize the divine power outline of the sun.

This is the real stunt of the Great Sun Concept Idea, only after cultivating to the consummation realm, can you carry out comprehension and mastery, after practice, you can really visualize the sun, and use mana to show the image of the Golden Crow, its power is more than ten times stronger than the Golden Crow Fu drawn before.

But.

This is obviously not a means that can be mastered by the Qi Refining Realm.

Su Chen didn't dare to try rashly at the moment.

Other than that.

In the past 60 years, Dachu has been relatively calm, and although there have been ups and downs in the country's fortunes, there have not been too many twists and turns.

Therefore, Su Chen's Dragon Sutra has not stopped progressing, and now, the qi and blood dragon shadow in his body has condensed into a small dragon ball prototype, and it is estimated that it will not be long before he can transform and give birth to a substantial young dragon, and he will get a lot of feedback at that time.

"The ninth layer of qi refining, I'm afraid this is already the limit of what I can cultivate in the mortal world, and if I continue to stay here, even if I have a lock spirit array, it will be difficult to improve. The island of Penglai is about to open again, and it's time for me to really leave and consider going to Middle-earth......"

"However, before that, let's go back to Chu Country by the way. Sixty years have passed, and I don't know what the situation is like outside......"

While thinking about it, Su Chen had already risen into the air, and the Yangjun Great Sword immediately appeared under his feet.

Now that he has enough mana and a strong divine mind, he can already try to fly with Edgeworth.

I saw that his feet stepped on the sword light, turned into a golden rainbow, broke through the air, and flew out of the valley.

The surrounding primitive tribes, seeing the vision in the valley of death, were all amazed, thinking that it was a miracle that the gods had clearly revealed, and they kowtowed to worship, and later there were some bold natives who entered the valley and found that the place where Su Chen had cultivated was now full of spiritual grass, and it had regained its vitality, and it regarded this as a proof of miracles.

As a result, some powerful tribes migrated here, and they called Yunling Grass the seed of the gods, which could help them drive out all darkness and evil, so they regarded it as a treasure and kept trying to breed and cultivate it, planting it all over the Far West.

This also led to a slow revival of the aura of the entire Southwest, many, many years later.

Of course.

That's all for later.

……

Half a month later.

Su Chen had already returned to the territory of Chu State.

After the cultivation was improved, the speed of Edgeworth's flight was naturally faster, and it originally took a few months to travel, but now it only took half a month to rush back.

The imperial capital of Chu is still prosperous.

Emperor Jin died fifty years ago, and then passed the throne to the Nine Emperor Princes of Dunhou.

As Emperor Jin expected, the Nine Emperors have a mellow personality and are the kings of Shoucheng, and the State of Chu has gained stability for thirty years, although there is no great achievement, but it has not caused any turmoil, and the foundation left by Emperor Jin is strong, everything inside and outside the court is in order, and the talents of Chu State are continuous.

As long as the emperor is not too stupid, there will not be much change in a short period of time.

Coupled with the secret support of Tsing Yi Lou, Sunflower Villa later accepted the canonization of the imperial court and became the state religion to protect the national fortune, and the status of the royal family was naturally more stable.

So far, the state of Chu has been passed down to the grandson of Emperor Jin, and changing the age to Changping means long-term peace.

Su Chen didn't stay in the imperial capital for long.

Sixty years ago, he had already arranged everything for the future, and Su Chen, a person, had long been annihilated in the long river of history.

As long as it is not a national movement, to the extent of changing the dynasty, he will not easily show up and interfere again.

And now that he is about to leave, there is no need to be involved in any cause and effect.

So he didn't go to Tsing Yi Building, nor did he go to Sunflower Villa.

It's just that before leaving, I couldn't help but go back to Kwai Yuan again and take a look at it from a distance.

Today's Kwai Yuan, has already changed its appearance, was transformed into a huge academy, I heard that it was the order issued by Emperor Jin in his later years, because he and the empress had studied here, so the four libraries of books were gathered here, transformed into the Royal Academy, the word "Sunflower", others thought it was in Yinghe Sunflower Villa, but only a few people knew that this was Emperor Jin commemorating the ancestor who may have long since left.

Xiao Lizi is no longer in Kwai Yuan.

Su Chen also specially asked someone to investigate.

As a result, it was learned that Li Yuan had left as early as fifty years ago, that is, shortly after the death of Emperor Jin, and his whereabouts were unknown.

It is estimated that he may have died of old age.

As for the King Kong spirit puppet left by Su Chen, it was invited into the Qiankun Palace by the current emperor, replacing the shadow guard of the year and becoming the emperor's most important talisman.

"Today's Chu State, as well as the remnants of the ancestors, can maintain its prosperity for another few decades, so I don't have to worry about it for the time being."

It was determined that the general situation in Chu was stable, and Su Chen did not delay any longer.

Then he went to the imperial tomb again to visit the deceased Emperor Jin, and then went to the graves of Lin Fan and Gonggong Li to burn paper to say goodbye.

"This time, it's really leaving. Next time I come back, I don't know when it will be......"
