The light and shadow changed, and in the blink of an eye, the sand table in front of Lin Tuo switched to a tiled continent.

It is surrounded by the sea, and in the middle is an irregular piece of land.

As the gaze falls, the slowly rotating day and night repeatedly coat the whole world with different lights and shadows.

As a space the same size as the north and south continents, time here seems to be quite slow, the most obvious manifestation is that Rao has been accelerated many times, but the continent is still not much changed from thousands of years ago.

Whether it is the architectural style or the social form, most of them are the same, of course, the dynastic power will also change, split, unify, alternate, and the sect will also rise, decline, fight, and unite...... There are grievances and hatreds, but there are really no similar changes in the social system.

It seems that no matter when Lin Tuo's eyes fall on this world, it is not too much.

This can naturally be attributed to factors such as the gradual development of society, or the emergence of the dynastic structure of the sect that greatly stabilized the regime, but I have to admit that, at least from the outside, it is always less changeable than the rest of the sandboxes.

And Lin Tuo was unexpectedly not disgusted by this.

When his gaze swept over the earth, mountains and rivers, the wisps of aether lines floating up were so clear, far from being comparable to the earth in terms of quantity, but the quality was the highest among several sandboxes.

Just as he had expected, the No. 3 sandbox has always been on the path of exploring the end of human evolution, and with the increasing number of high-grade and even inhuman cultivators, the evolution speed of the sandbox is also steadily declining.

"Sure enough...... The evolution of the human body is also one of the important factors influencing 'complexity'......"

Through the change of light and shadow, the calculation time, and the comparison with the record in the book, Lin Tuo confirmed this conclusion:

"According to this trend, maybe when someone lights up the seven veins and is promoted to a higher level, the third world will also be the same as the first two, and it will come to a standstill."

Lin Tuo thought, sitting in a wicker chair, holding a notebook in one hand and a ballpoint pen in the other, sketching and sorting out his thoughts at will.

"The earth's potential is being tapped, and it is steadily improving, and the ether is growing steadily, so it is not suitable for harvesting."

"The No. 4 Moon Sea Continent has come to a standstill, alchemy has reached a certain level, and the etheric environment is stable, but the total amount is small, so it is not suitable for collection."

"The North and South Continents of No. 3 are still in a period of civilization expansion...... Moreover, the operation of a large number of mana facilities is also consuming ether, so it is not suitable for collection. ”

"......" Lin Tuo was silent, and suddenly found that the source of his ether was only the number three in front of him.

However, because of the increase in complexity, one day in reality is now a few decades later.

During this time, Lin Tuo did not forget to collect from time to time, and the aether in his body also increased a little, but he was still a lot short of opening the sandbox again......

Unless he only opened a small sandbox, which would be barely enough, but that would be pointless.

"I'm so poor......"

After a few months, Lin Tuo once again expressed the feeling of being poor, but he couldn't find any way to open source, so he could only wait patiently for a while.

But he wasn't going to wait.

Now that the development of the sandbox has entered a stable period, his own evolution must be put on the agenda.

More specifically, it is to find a way to light up the seven veins.

"Riding the Red Dust......

With a light movement of the pen tip, Lin Tuo wrote these three words on the paper:

"According to the "Demon Classic", it is known that the most effective way to light up the meridians is to experience and travel in the red dust, and I have no shortage of places to travel, but the problem lies in the ...... of time."

It often takes decades or hundreds of years to travel, which is difficult for Lin Tuo to accept at present, and according to previous experience, the "resurrection" ability combined with the acceleration effect of the derivative sand table can greatly speed up this process.

Although "resurrection" is limited by the negative effects of "sinking" and can't last long, it can help him save more than half a year at a time, and it is also quite impressive to come a few more times.

"Moreover, I can also use this ability to further familiarize myself with and hone my mastery of power......"

"I've been promoted too fast, I have a lot of aether, but I'm a lot worse in terms of utilization, the sword qi storm that strangled the one-eyed giant looks gorgeous, but in fact, a lot of sword qi is wasted, which shows that my mastery of power is still lacking......

Last time, parasitic mountains and seas consolidated my understanding of alchemy and the magic system, and this time I can completely change the body of a cultivator, and exercise my control over power with the help of walking in the red dust. ”

"By the way, you can also teach Huaxi by the way."

This time, he was going to bring Huaxi with him.

First, according to the "Demon Codex", it is better to be alone than many people, and secondly, it can also be more convenient to prevent "sinking", in addition, since Huaxi mastered the Huabing Fist, Lin Tuo has indeed rarely trained her.

According to Lin Tuo's plan, in order to facilitate the coordination of various worlds, he did need to arrange assistants in different worlds.

The base camp of the earth has Li Tai and Jiang Yishan.

The Moon Sea Continent has blue sky and Sesai.

The North and South Continents are now garrisoned by Hathaway.

Only the third world is left, and due to the acceleration of time, there has never been an arrangement, but it will be sooner or later.

If you can, cultivate Huaxi, and it will be safer to let her garrison No. 3 in the future.

"But you can't go straight in, you have to make some arrangements." Lin Tuo suddenly realized the risks behind it.

There are many sects in the No. 3 world, and there are many cultivators.

If you want to polish your strength, you can't choose to be an ordinary person safely, on the contrary, you need to take the initiative to look for danger and find battle, and your parasitic state will not be too strong......

At the very least, he didn't feel that he could find a suitable carrier of the "inhuman environment......

Based on his previous experience with the "resurrection" ability, when the ability is activated, if you die again in the sandbox, even if you can return to the main body, there is a high probability that you will be traumatized......

This is still himself, if Huaxi's life is in danger and he has no time to rescue, then he is really dead......

After thinking about it, Lin Tuo felt that he had to arrange a backhand.

"What to do?" After thinking for a while, Lin Tuo suddenly remembered the last time Lu Tang's candidates went to the wasteland to practice, and remembered that at that time, the imperial court also arranged for the strong to secretly protect ......

In addition, I heard that some children of big families will go out to practice, and they will also invite masters to accompany them in case of accidents, and there is a special word called "protecting the road......

At that time, he just listened to the customs, but now he has inspiration.

"It would be nice if I could find a group of people to protect my path......"

The thought arose, and Lin Tuo suddenly had a plan in his heart...... After a little thought and confirmation that it was theoretically feasible, Lin Tuo immediately manipulated the virtual panel, turned off the acceleration of the No. 3 sandbox, and then closed his eyes and entered the "phantom space".

In the blink of an eye, Lin Tuo appeared in the void, his mind moved, the surrounding scenery changed, a wasteland appeared under his feet, and behind him was a giant tree that seemed to be about to open the heavens and the earth, and above his head was a sky map......

It is a scene that imitates the place where the book of heaven was handed down in the wasteland.

Lin Tuo took a few steps forward, waved his hand to conjure up a lake and a thatched hut, and a cloak embroidered with dark gold patterns appeared on his body, and Shi Shiran sat down in front of the thatched hut.

Then he raised his hand a little, and two futons appeared in front of him, on the left futon was a kneeling and sitting Hua Xi in the same costume, and on the right was a figure with a hood covering his face.

After thinking about it, he spread the mist again, and then he suddenly raised his hand and sketched the "Transmission Dao Pattern" hidden in the three volumes of Heavenly Books in the space and activated it.

……

At the same moment, World Three.

Located in the ancient capital city in the north of the mainland, it is early spring at this time, and the weeping willows in the city are slightly green, and the stamens are beginning to bloom.

In a quiet and tidy urban area, there are antique buildings full of green plants, red walls and black tiles, arched corners and cornices, which are very magnificent.

In the hall of the building, some people competed, some people meditated, and wisps of bright etheric silk threads spread into the sky.

exudes an inexplicable majesty.

In contrast, the main entrance of the building is unexpectedly shabby, only a small one, but no one dares to take it lightly.

Just because this is the "Qintian Dao Academy" that has been inherited for thousands of years, it is a legendary place that has been passed down for thousands of years with the Heavenly Dao Sect and the Demon Capital.

However, on this day, the renovated main hall of this ancient building revealed a strange fluctuation of vitality, attracting countless teachers and students in the Taoist courtyard to look at it in amazement.

"Whoosh-"

Suddenly, a sword light pierced the sky and went straight to the main hall, causing the students in the academy to exclaim:

"That breath...... Is it the dean? ”

"What happened? Alarmed the dean of the sky?! ”

……

In the south of the continent, in the mountains, the Heavenly Dao Sect, which has been inherited for thousands of years and still stands, is peaceful.

“…… When you draw your vitality with your mind and travel until Sunday, you can ......" In the square in front of the main hall, a sect teacher is talking about the cultivation course to a group of inner disciples.

Below, the disciples either listened attentively or became drowsy, and so on.

"Boom!" Suddenly, a crisp bell chimeled the birds flying all over the mountain, and a group of disciples and the teacher were also stunned on the spot.

Then, everyone noticed the fluctuation of vitality coming from the main hall.

"The picture scroll in the main hall is moving!"

A sharp-eyed disciple shouted.

The rest of the people also saw the source of the vibration of the vitality, which was the picture scroll that had been hanging for countless years in the main hall with the two big characters "Heavenly Dao" written on it.

It is said that the scroll has existed since the beginning of the sect.

But why did the change today cause the bell of the sect to ring?

"It's the Sect Master!"

Suddenly, someone was surprised to see a figure floating down at the door of the main hall.

The contemporary sect master hurriedly walked into the hall, as if he had thought of something, his expression changed suddenly, and then dispersed the crowd, closed the door and bowed, forcibly suppressed the palpitations, entered a state of meditation, and sketched the transmission pattern in his heart.

……

In the west, among the 100,000 demon mountain arch guards, it is the demon capital.

It was a sunny day.

In the demon capital, the "Demon Emperor Tower" that Lin Tuo had visited "not long ago" suddenly shook, and the light was shining!

Attracted the attention of countless demon clans!

In a corner of the city, the fourth-generation Demon Emperor spread his wings, swept the wind, rushed into the Demon Emperor's Tower in the blink of an eye, broke open the eaves, and looked at the dazzling Dao pattern left by the first-generation Demon Emperor in the dome hall, his expression changed, and he whispered softly:

"Haotian ......"

Then fold his wings, kneel on the ground, and sketch the corresponding pattern in his consciousness.

……

A moment later, three bright, thick aetheric lines rose from this continent, heading straight into the sky and entering the illusion space created by Lin Tuo.

The three powerhouses of the current era, with fear and excitement, let the will of "Haotian" come.

Then, the same picture appeared in front of the eyes of the three people:

On a lonely wasteland hanging in the void, a towering giant tree seemed to open the heavens and the earth, and in front of a thatched hut under the tree, there were three figures.

Two of the smaller ones, with their backs to the three of them, are in a kneeling position, while opposite the two are a mysterious and mysterious figure that exists only in legends.

From this angle, the man's face was just right to see.

The three of them were stunned at the same time, first they felt familiar, and the next second, they recalled at the same time that they had treasured the character picture scrolls in the classics of their respective forces, and then recognized Lin Tuo's identity:

"Haotian...... Emissary! ”
