The two had a common mind, and without saying much, Shen Chaixing walked over and picked up the stone box, feeling quite heavy. Blue Moon gently opened the stone cover.

Suddenly, the two of them felt their hairs stand on end, and then a purple qi floated out of the stone box, circling around the two of them. The true qi in the two of them was naturally aroused, and an aura was generated to protect their bodies.

The purple qi first rotated slowly, then faster and faster, and more and more, and after a while, the entire stone chamber was shrouded in purple qi.

Then, all the purple qi slowly converged little by little, and finally converged into a dazzling purple light. The two of them were in a state of panic when the purple light suddenly rushed into the sky.

The two looked up, and for a while, everything around them seemed to be gone, everything in the stone chamber and the secret passage seemed to have disappeared for the time being, and the two seemed to be standing under the endless void, looking up at the starry sky, and saw that the purple qi flew higher and higher, rushing straight between Dousu and Niusu.

I don't know how long it took for the two to come back to their senses, everything was the same, the two were still in the stone room, but the stone box had been put aside, and each of them held a sword in their hands. Shen Chaixing's sword, the sword was three feet long, the two of them looked down at the sword body, and suddenly felt like climbing a mountain and looking down at the abyss, ethereal and deep, and there was a giant dragon lying in the abyss. The body of the sword is engraved with the ancient seal character "Longyuan".

Look at the sword in Lan Yue's hand, it is three feet three inches long, the sword body is green all over, and it is engraved with a pattern as thin as turtle scales, shaking gently, like a dragon out of the water. Leaning over to look closely, I felt that there seemed to be a kind of majestic aura hidden in the sword, a kind of unyielding king and tyrant spirit. This kind of momentum is usually hidden in the sword and is easily not released, but once it is issued, it will be earth-shattering and unstoppable. There are also two seal characters on it, "Taia"!

Shen Chaixing doesn't know why, but Lanyue is well-read, and has a soft spot for weapons, of course he knows the origin of these two swords, so he simply told Shen Chaixing: The legend of the sword held by the two was jointly cast by Ou Yezi and the cadres during the Spring and Autumn Period and the Warring States Period, and a total of three handles were made at that time, and there was a "Gongbu", which was later missing. The first owner of these three swords was the king of Chu at that time.

Later, Wu Zixu once owned the Longyuan sword, and legend has it that Liu Bang used the Longyuan sword to cut the snake. Tang Gaozu Li Yuan wore this sword, because he avoided Li Yuan, so he changed the name of "Longyuan" to "Longquan".

The "Tai'a" sword was worn by Qin Shi Huang Yingzheng, and his whereabouts are unknown.

Unexpectedly, these two world-famous swords actually appeared here, and the two of them were not very interested in treasures, but they didn't feel that the trip was worth it until this moment, and they were busy putting the swords on their bodies. Shen Chaixing smiled and said to Lan Yue: "There is such a coincidence in the world, Liu Bang's sword to cut the snake is here, we don't have to be afraid of the python spirit now, now it should be its turn to be afraid." It can be seen that the things in the world are mutually reinforcing, which makes sense. ”

With these two swords, the two of them were no longer interested in looking at other weapons, so they closed the stone door and came to the last stone room.

This stone room is different from others, with a round stone table in the middle, two stone benches on one side, and a circle of bookshelves around it, all of which are well-packed books. Open the package, some are the classic books of the Mo family, some are the geography of the mountains and rivers of the country, detailed records of the waters and rivers in various places, the roster of Momen disciples of previous dynasties is also among them, there are also some military books and war strategies, and even a large shelf of martial arts cheats, Lan Yue and Shen Chaixing don't seem to be interested in these, and the two always feel that something is missing.

Lan Yue sat on the stone bench and thought for a long time, and suddenly turned the stone table in front of him two squares to the left and three squares to the right, only to hear the sound of "gurgling", the stone table rose, Lan Yue pushed the stone table to the side, and a small stone pit appeared, and a small square stone box was placed inside.

Shen Chaixing jumped down and lifted the stone box to the ground.

The two of them took a closer look at the stone box, the shape was simple, it was actually made of black jade, the lid and the body of the box were tightly seamless, and there was only a small groove in the middle. Shen Chaixing didn't open the stone box after tinkering for a long time, and was about to smash it open with a stone, but was stopped by Lan Yue.

Shen Chaixing smiled: "Are you distressed about this jade box? There are many such things in this house, one is smashed, and there are a thousand." ”

Lan Yue said: "Don't you take a look, all the things in the entire treasure are placed in a place that can be seen by the human eye, even these two rare swords are only placed in a corner at random, and this box is arranged in a mechanism, do you think about why?"

Shen Chaixing said: "You mean to say that the contents of this stone box are the most important and valuable in the entire treasure?"

Lan Yue nodded, "In that case, what do you think will happen after that box is smashed open?"

Shen Chaixing guessed: "You won't release anything from it to kill me both, right?"

Lan Yue said: "You are really imaginative, what can a box of such a size hold, it is not necessary to destroy the treasure or kill us, but I am sure that the contents of this box will definitely be destroyed with this box." "Qimen Dunjia" records such a kind of box, a small mechanism, if forcibly opened, there will be an explosion inside, or burning, or spewing out corrosive liquid, in short, the treasure inside and the outside box will be destroyed together, and no irrelevant people will get it, it is really a jade burn. ”

Shen Chaixing asked, "Then what should I do now?" I worked hard to come to the treasure and saw a lot of these gold, silver and jewelry, but I couldn't see the most valuable thing, didn't I enter the treasure mountain and return empty?"

Lan Yue said with a smile: "As the saying goes: A key opens a lock, and you come to me every day with that key?

Shen Chaixing patted his head and said, "I always feel that something is wrong, as if something is useless." As he spoke, he took out the jade pendant in his arms and inserted it into the groove of the jade box.

Lan Yue said: "You can see that the bright color and texture of your jade pendant are consistent with this jade box, and it is clearly made of the same piece of jade. Shen Chaixing took a look, but it was not so, the jade pendant was inserted into the jade box, which was perfectly unified in terms of color, texture, and material, without any sense of disobedience, just like a long-lost wanderer returning to the arms of his family.

Shen Chaixing pressed down gently, only to hear a very light "click", the lid of the box was loose, Shen Chaixing gently opened the lid of the box and put it aside, it seemed to be some parchment and some specially processed paper, and there seemed to be a letter on the top.

I opened the letter, and at the beginning I wrote: "The things in this jade box are the core of my ink gate, and those who are lucky enough to see this letter and treasure box must first make an oath and enter my ink door before they can see the rest of the objects, otherwise God will curse it, the gods and ghosts will hate it, and the disciples of the ink door will punish it." ”

Below is actually a vow to join Momen.

The two looked at each other for a long time, and finally Lan Yue said: "I have a good relationship with the people in Momen, and the eldest brother also intends to let me join Momen, so it doesn't hurt for me, but this form is a bit hasty." ”

Shen Chaixing said: "The ancestor of Momen should be Mo Zhai, right? I look at the two sentences on his portrait in the hall, which are not bad, 'the benefits of the world, and the harm of the world', it will not be far from being able to have such an ideal sect, and I am one of them!"

The two of them immediately fell to their knees and swore to join the Momen according to the oath stated in the letter.

Looking further down, it is a simple explanation of some simple gestures of meeting the Momen, and there are also some secret marks of the Momen calling the same door, etc. In fact, the two of them don't know, if their current gestures and marks are seen by the people in the Momen, they will know that the two of them are the identity of the first disciple of the Momen, and the first disciple is not a person, but a status, second only to the identity of the giant in the Momen, and only the first disciple can be promoted to the giant.

Looking further down, the letter tells an eternal secret of Momen: at the end of the Spring and Autumn Period and the beginning of the Warring States Period, Mo Zhai founded Momen, which was in the limelight at that time, and its momentum overwhelmed the most powerful Taoists and Confucians at that time, and the world joined one after another. Since Mozi was not only a great thinker, but also the ancestor of craftsmen whose skills surpassed Luban's, Momen also attracted a large number of craftsmen to join.

At that time, the main work of craftsmen was to build palaces and mausoleums. In the end, the craftsmen who built the mausoleum were imprisoned in the mausoleum they built, suffocated and starved to death.

Seeing that reasoning with the nobles of the palace who built the mausoleum could not change their actions, Mozi asked his disciples to build a secret escape passage when building the mausoleum or palace, so that these craftsmen could escape by being locked in the mausoleum after completion.

Since then, generations of Momen disciples have not only built secret passages when building mausoleums and palaces, but also habitually built secret passages when building cities, so as to leave back roads, and draw the shapes of these secret passages into drawings and hand them back to Momen for safekeeping, in case of emergency. A few years later, if the Momen people who rebuilt the palace and city saw the secret passage built by their predecessors during the construction, they would also cover it up, add designs to the original foundation, and draw a map and hand it over to Momen.

All in all, for thousands of years, there are secret passages of different sizes and sizes under the ancient cities of the world, and some are even underground cities, some of which have been destroyed, but some have been inherited and maintained by the later Momen people, and drawn into diagrams, and the most important drawings are in this jade box. Whoever owns these drawings owns this vast underground world. As a result, the value of these drawings far exceeds the sum of the other items in the treasure.

When Lan Yue saw this, he suddenly became excited, and he tried his best to control his emotions to look at those maps, Chang'an, Datong, Luoyang, Kaifeng, Beiping, Jingzhou, Yangzhou, Yingtianfu••••••

The map of the secret passage of Jingshi Ying Tianfu was impressive, and Lan Yue took out this drawing and spread it on the stone table to look at it carefully. Because Shen Chaixing had been to Jingshi, he also came over and watched from the sidelines. After a long time, Lan Yue put the drawing of Ying Tianfu back in its place, and at the same time closed the jade box again, put it back into the underground mechanism, and handed the jade pendant to Shen Chaixing after closing, and said, "It's time to leave, do you have anything you want to take away?"

Shen Chaixing said: "I think these two swords are very good, it seems that they are specially reserved for the two of us, and the others should be left here." Now that you and I are both from the Momen, he will hand over this treasure to the Momen Giant in the future!"

Lan Yue nodded yes, opened the stone door, and saw the huge body of the python spirit blocking the door, waiting for the two of them with their blood basin mouth open.
