Tianlan Sect to the northwest more than 300 miles, after a canyon, is the Tianlan Secret Realm, the Central Continent, now should be called the Huaxia Continent monks know the secret realm but four, one of them is the Tianlan Secret Realm, and there is a big island in the East China Sea, controlled by the Haitian Sect Secret Realm Fusang Secret Realm, that secret realm opens every fifty years, the next time it opens is ten years later, there are two secret realms are no longer secret realms, most of them have been revealed, due to the damage of the formation, excessive mining, has become a ruin, many places in the middle because the formation is not completely invalid, but it is also more dangerous, many scattered cultivators often linger, occasionally found。

The monks fell into the light, Shao Yan looked fixedly, in front of him was a wasteland, overgrown with weeds, birds and birds flew by from time to time, it was an endless wasteland, Shao Yan knew that it was a false appearance, this radius of two thousand miles was actually a secret realm, as long as you found a way to enter, it was another world.

The three elders of Tianlan Gate each took out a token, and the moon and stars were painted on one side, Shao Yan's eyes were sharp, and he found that there were more stars on it than in the sky now, and he thought to himself, I don't know if anyone in Tianlan Sect has paid attention to this; on the other side of the token is the mountains and rivers and the earth; and the last token is the scene of people hunting and working. Shao Yan had a vague idea in his heart, these three-sided tokens seemed to be the three talents of heaven, earth and man, and he didn't know if he would form a three-talent array.

As if in order to verify Shao Yan's thoughts, the three elders made hand seals, and the three-sided tokens floated in the air, forming a three-talent array, three rays of light shot out, the space in front of them fluctuated, and a passage appeared, and from the passage, you can see the green mountains and green waters inside.

An elder spoke: "Fellow Daoists, the opening time at this time is the same as before, it will be sixty days, and this door will be reopened after sixty days, I hope that the disciples of all sects will rush back on time, otherwise, they will wait until the next secret realm is opened, but no one in history has waited for that day!" After finishing speaking, he signaled the disciples of each sect to enter, and the disciples of each sect to enter in an orderly manner, and when all the Qi refining disciples entered, the passage was closed.

As soon as the passage was closed, the elders of each sect and other people who led the team found their own places to meditate, waiting for the secret realm to reopen after sixty days, Shao Yan mobilized his eyes, the world began to become transparent, Shao Yan looked at the secret realm, everything in front of him made him dumbfounded, the person who built the secret realm was so generous, this is no longer an ordinary formation, it can be regarded as Shao Yan has seen the formation to the extreme.

It is also developed by Shao Yan's eyes, he can see the truth through layers of obstacles, no one in this world can see the essence, except for Shao Yan, only Wuyin may be able to see through, Wuyin is because of the way of cultivating heaven and demons, the world wants his eyes to be as transparent as glass, the world is made of force, and before Wuyin, no one can achieve the current achievement of Wuyin.

Shao Yan is now in the southeast of the secret realm, although he can't see through the entire secret realm, but everything in front of him makes him understand the general composition, above the leyline, four bucket-thick pillars, as if it is red copper, deep into the ground, hooking up the leylines, looking to the left, that is, the south of the secret realm, nine big pillars, buried deep underground, hooking the leylines, Shao Yan is too familiar with this way, although he has not seen the whole picture, Shao Yan knows that this is the arrangement of Luoshu, and there is even a spirit turtle song: "Two or four is the shoulder, six or eight is the foot; wear nine shoes one, left three right seven; five in the middle, equal in length and width." That is, the third-order magic square in mathematics on Earth.

Looking at the top of the pillar, according to the heavenly stem and the earthly branches, sixty jiazi should be formed in a circle, looking up at the sky above the secret realm, but it is from the underground pillar to extract the qi of the leyline, with the power of time and space of the sixty flower nails, and take the power of the sky and stars to form a phantom of the river map, Shao Yan couldn't help but be shocked in his heart, from the underground to the sky for more than 2,000 miles, lay out such a large array, use the leylines of Luoshu Town, draw the aura of the earth's veins, borrow the power of time and space with the power of the sixty flower nails, distort the space, and borrow the power of the stars with the river map to stabilize the space. The combination of the three not only makes the spatial distortion disappear, but the internal space area is probably two or three times that of the outside, and the aura is sufficient.

Shao Yan saw all this with his own eyes, and he understood the essence of the secret realm from the principle, if the cave heaven was a small world space opened up by the great supernatural powers directly from the void, then the secret realm was to distort and hide a piece of space in reality to form a closed small space, and he couldn't help but admire the power of the ancient monks.

Although he understands all this in principle, Shao Yan still doesn't know the details of the structure at that time, no wonder that the monks can't build the secret realm now, even if they learn something from it, it also costs a lot of spirit stones to expand the capacity in the cave, and the secret realm does not need to use spirit stones, but with the help of powerful underground leylines.

Long Mutian saw that Shao Yan had been standing in the secret realm for an hour, and knew that the master had comprehended something, so he stood next to him to take care of the master, and the other elders saw this, so it was inconvenient to disturb them.

After Shao Yan saw all this, he saw Long Mutian guarding by his side, and he was a little moved in his heart, and said to him: "You go by yourself, leave me alone, I will go around the secret realm, it may take a few days, you and other Taoist friends to communicate." After speaking, Yun Sheng stepped down, followed the edge of the secret realm, looked all the way, and finally checked one side, it was a clear understanding of the composition of the formation here, it took a whole day, Ming Shang's eyes opened for a day, Shao Yan was already Jindan six turns, still couldn't bear it, it had been thousands of miles away from Long Mutian's location, and he didn't go back, just on the top of a mountain peak next to him, he opened a small cave, laid out a formation, took out a jade slip, and carved what he had obtained into the jade slip, his whole body relaxed, and he entered a deep state of concentration, until the next three rods, he woke up from the meditation, and his spirit had completely recovered, as if there was a trace of progress in cultivation。

Shao Yan made persistent efforts and continued to check, just like that, it took twelve days, not only to find it on all sides, but even the middle flew over the secret realm, and checked it again, fortunately Shao Yan developed his eyes, otherwise there was no way to check it, Shao Yan tried it with his divine sense, and his divine sense could not enter at all.

When Shao Yan returned to the starting place, he found that there were a lot fewer monks, and the secret realm was reopened after sixty days, many monks simply went out to travel, and the remaining monks had opened caves on the cliffs on both sides of the canyon.

Long Mutian saw the master come back, and immediately came to see the master, Shao Yan followed Long Mutian to his newly opened cave to sit down, Long Mutian asked Shao Yan if he wanted to open another cave, Shao Yan shook his head, said that temporary residence, one cave is enough, asked what happened in the past ten days, Long Mutian replied that there was nothing to do, many monks went out, and the remaining monks either found the old cave mansion, or opened a cave mansion by themselves.

Shao Yan jokingly said that if he was the head of the Tianlan Sect, he would send someone to open up and manage the cave mansion, and then, take advantage of the current time to rent it out for a fee. Then talking about his own investigation of the situation this time, Long Mutian was very surprised after hearing it, he has been practicing in the Long family since he was a child, and he knows more about the things in the cultivation realm, the secret of the secret realm, for many years, many sects want to decipher, but no one has completely figured it out, although many sects have learned a lot of things from it, but it is still far from unlocking the secret, no one can arrange a secret realm, listen to the master's meaning, he went out for more than ten days, and figured it all out.

Although Long Mutian was surprised, he also knew that he couldn't speculate on this master with common sense, so he asked with some disbelief: "Master, are you saying that you can recreate a secret realm?"

"Yes, when I go back to the mountain this time, I will prepare and build a small secret realm. Where is it? Huozao Mountain, no, if this place wants to open up a cave in the future, then choose Beppu in the Yilan Mountains. Shao Yan pondered for a while, and chose the location to build the secret realm, he said it as a matter of course, but Long Mutian was stunned in place, because Shao Yan casually mentioned that he wanted to open up the cave, but he had entered the cave, it was a complete small world, said that the moon meridian was traveling, everything was vibrant, Long Mutian couldn't imagine how to open up the cave, Shao Yan actually understated that he wanted to open up the cave in Huozao Mountain.

Shao Yan noticed Long Mutian's abnormality and asked puzzledly, "What's wrong with you?"

"Master, you mean..."Long Mutian swallowed a mouthful of saliva, calmed down and said, "You mean to open up a cave heaven that is the same as the Azure Cave Heaven?"

"That's right, what's wrong?" Shao Yan found that the disciple was a little abnormal, thought about it for a while, and suddenly understood, and couldn't help laughing: "Mu Tian, you have been by the master's side for many years, you know that the master pays attention to comprehending the way of heaven and earth, and those who have obtained the Great Dao, those who open up the world and other idle things, although the master has not obtained the Great Dao, but he has opened up a cave sky, and when the master enters the god in the future, he can still do it, not only the master can do it, but you can also do it to that extent, and you must have confidence in yourself." ”

"I'm sorry, master, I lost my temper. Long Mutian began to reflect on himself.

Ji Xiangran's voice came from outside the cave: "Senior Shao, Senior Brother Long, Xiangran and Uncle Yun are coming to visit!" Ji Xiangran and Yun Tianxing also opened two caves not far from the Longmu Tiandong Mansion, and today I saw Shao Yan come back and came to visit.

"You're welcome, you two, please come in. Shao Yan said.

The two of them entered the Tianwai Gate, and when they saw Shao Yan, they thanked Shao Yan for taking their disciples with clouds. Originally, as soon as they arrived here, the two wanted to say thank you, but Shao Yan began to check the secret realm, and it was inconvenient for the two to disturb, and later, Shao Yan went out alone, so it was delayed until today, so when he saw Shao Yan coming back, he came to thank him.

Shao Yan invited the two to sit down, although the cave was simple, but Long Mutian such as a futon was prepared, and the two sat down on the futon. Shao Yan asked about the situation of the Tianwaimen in the past year, Ji Xiangran said that the situation of the Tianwaimen was very good, everything had shown a vigorous upward trend, and a lot of spells suitable for them had been studied, for this, Ji Xiangran specially thanked Shao Yan, if it wasn't for Shao Yan's "The Secret of the Earth" to open their minds, the elders would not have thought of starting from this angle. For this reason, Ji Xiangran said several spells that the elders in their sect had studied, and when Shao Yan saw it, he knew that it was the same as the "Secret of the Earth Evil", but it was more aimed at their own situation.

Talking and talking, Ji Xiangran asked a question, can there be a way to let the disciples of the no realm fly into the air. Shao Yan fell into deep thought, and suddenly had a flash of inspiration, since he couldn't fly, why couldn't he make something like a magic weapon that could carry people. Shao Yan said his thoughts, the two people from the Tianwai Gate were very interested, if they could control a magic weapon and bring multiple disciples, then, wouldn't the embarrassing matter of that day be solved?

Shao Yan also came to be interested, after discussion, simply build a flying boat, which can carry about twenty people, and the hull is often used to refine magic weapons in the floating array, and if one person drives difficulties, he will use spirit stones to drive, and the monks only need to stimulate the spirit stones and control the direction and speed. Just do it, Shao Yan took out the pen and paper in the ring, and began to draw drawings, fortunately, Shao Yan majored in science and engineering in his previous life, and he was no stranger to drawing, and soon, the drawings were drawn, but it was a long and narrow sailboat, with a floating array on the hull, a wind gathering array on the mast and sail, and some other formations, all of which were driven by spirit stones to produce different functions.

Drawing drawings and marking the dimensions, Shao Yan began to calculate the amount of materials, Shao Yan had a feeling of returning to his previous life, drawing drawings in the office.

The whole ship is made of wood as the main material, in this world, there are not a lot of wood for magic weapons, and the peach wood for hundreds of years is a very low-grade refining material, generally used as a decoration material for the interior of the monk's cave or house, if it is lightning strike wood, the price is a little more expensive, Shao Yan decided to use more than 100 years of peach wood as the keel, and the outer Mongolian paulownia wood, more than 100 years of paulownia wood is also a low-grade refining material, but most of the monks are also used for some decoration, the price is slightly more expensive than the peach wood, the mast is made of peach wood, and the sail is made of the skin of the surname demon beast.

After calculating the amount of materials, Shao Yan decided to refine one himself, so he made a list of materials, most of which were wood, and the other was some refined silver, cinnabar, etc., and copied two copies, one for Ji Xiangran and one for Long Mutian, and asked them to go to the Fang Market near Tianlanmen to buy materials according to the list.

Ji Xiangran, Yun Tianxing and Long Mutian set off together, got up with their weapons, and headed for Tianlanfang City.
