Fang Tai followed the girl up the stone stairs.

The stone ladder is narrow and steep, allowing only one person to pass through, zigzag all the way up.

Unlike the secret passage when the two came, abrupt bends appeared from time to time, and the bends of this road seemed smoother, like a spiral.

And according to the way the two of them explored the way before, they didn't encounter even a single trap.

It seems that the road is simply passable, and there is no reason to install those security measures.

Three or four feet up, a stone gate appeared again in front of the girl, and it was only the size of a person.

Judging from the situation of the two of them along this secret road, it denied Fang Tai's conjecture about this road.

If it's a road for transporting supplies, there's no reason to make it so narrow, and the door to get in and out doesn't need to be so small.

It seems that this road has other uses, and the passage dedicated to transportation has not been found by the two of them in the cave just now.

So what could be the place behind this stone door?

This time, the question didn't stay in the minds of the two for long.

Because an extremely obvious handle appeared next to the stone door.

With just a flick, the secret behind the stone gate will appear in front of the two of them without concealment.

Nearly two hours have passed since entering the tunnel.

When Fang Tai and the girl met, it was already after dusk, and it should have been close to midnight by now.

For a long time, the two of them still have palpitations when they recall the several dangers they have experienced.

At this time, facing the hope that was close at hand, Fang Tai had an inexplicable sense of unreality.

And that's the end of it? What are the pitfalls behind this? Secret? Fight? Or ...... A labyrinth with no end in sight?

Fang Tai took a deep breath, reached forward, and grabbed the handle.

With a force on his wrist, the stone door opened smoothly without a sound.

Behind the door was a large black wooden plank, which tightly blocked the entire exit.

Fang Tai held his breath and leaned over to listen carefully on the wooden board.

I couldn't hear any movement outside for a long time.

He knocked on the wooden board, making a hollow "thump" sound, which appeared to be the back of some kind of cabinet.

Fang Tai and the girl looked at each other, and then he pushed hard with his hand against the side.

This time it really worked!

With the sound of rubbing, the plank slowly moved away, and a light came through the crack.

When the exit was expanded, Fang Tai walked out first with a gun, and the girl followed.

What catches your eye is a circular room surrounded by various cabinets and tables, with a round table in the middle.

They came out of the back of a cabinet, and after pushing it back into place, the two looked around the room.

On the cabinets and tables, there are all kinds of porcelain, antiques, precious stones, gold and silver ingots, the four treasures of the study, etc., and some calligraphy and paintings that look very old are hung on the walls.

In addition to this, there are many intricately shaped utensils.

It looks like the ones found in the cave, and I don't know what they are used for, but the material is no longer made of wood, but made of metal.

On the round platform in the middle is a wood-colored column one foot high and five inches wide, with two golden characters written on it - Tianzhi.

There is a black long box under the column, which is exactly what Zhao Feiqing is holding today, the former king of hidden weapons-Bafang Wind and Rain Box!

It seems that the two of them finally overcame all difficulties and found the treasure palace of Youlong Villa.

The girl stepped forward a few steps forward and picked up the wind and rain box, and said happily: "Ha, this time I can be regarded as finding it!" ”

Fang Tai also stepped forward to check.

It was the first time he had observed the King of Hidden Weapons so closely.

The box is heavy, and I am afraid that there are not thirty catties under weighing. The whole body is made of black wood, but there is no gap in the surface of the assembly, and it is seamless and seamless.

Rao is Fang Tai was able to take a closer look, and he could only find a few shallow straight scratches from the box.

Ren is Fang Tai was unwilling to take it and searched up and down, left and right, and couldn't find where the swift Wind Crescent Blade flew from, and he couldn't see how those hidden weapons such as Tianrose, Heart Piercing Pill, and Butterfly Dart were stuffed into this three-foot-long box.

"It's really ingenious!"

Fang Tai stroked the smooth surface of the box, shook his head and sighed.

The girl became more interested in the column: "Look at this thing, it can be put together with this wind and rain box, and it will faintly press over it, I don't know what kind of treasure it is?" ”

Fang Tai put down the wind and rain box and held the cylinder engraved with the word "Tianzhi" in his hand.

It is a little rough to the touch, and it looks like a log that has been soaked for countless years, but the wood is still tight and there are no signs of cracking.

"Tianzhi ......"

Fang Tai remembered what the old owner of Liu said to the housekeeper Liu Feng in the study: "...... and Tianzhiling put together ......"

"Tianzhi Order? Could it be that this is the inheritance token of the Liu family? I heard rumors that every time the Liu family succeeds to the throne, they have to ask for a long-standing token to witness the handover of the head of the family, but they are always covered with red silk cloth to prevent people from seeing. I think this is it! As soon as the girl heard Fang Tai say, she also told her guess.

"Is it a token of the head of the family? Not...... And that makes sense...... Didn't you tell me before that the Liu family inherited the Mo family inheritance from the Qin Dynasty, and this Tianzhi Order should be one of the Mo family's order hundreds of years ago. ”

"Moment Order? It is rumored that only the leader of the Mo family, the Juzi, can be in charge? How can there be one more? Could it be that there is more than one of these things? ”

Fang Tai nodded and said, "It is recorded in the history books that the Mo family was established by Mo Zhai, with strict discipline and advocating benevolent government. He is the author of "The Book of Ink", advocating both love, non-attack, Shangxian, Shangtong, Tianzhi, Ming ghosts, non-life, non-music, festival funeral, and economy.

Among them, the eight articles of love, non-attack, sage, shangtong, ming, ghost, non-music, festival and funeral, and thrift are all Mohist concepts for governing the country, and Tianzhi and non-fate reflect their thinking about the truth of the world.

"They believe that there should be a unified scale as a unit of measurement in the world, and everything must follow external standards to operate. In this way, the heavens should also have degrees, and people should have the measurement of heaven, so it is called Tianzhi.

"Fate is to deny the fate of the world. They believe that the world is fair, that those who rely on it will survive, and that there is no power in the dark as a rule.

"This kind of thinking is not recognized by the monarchs of the world, especially contrary to the Confucian theory of the Mandate of Heaven, and in the end it was finally suppressed by Emperor Wu of the Han Dynasty 'deposed a hundred schools of thought and respected Confucianism alone', and the suppressed lost space for existence and gradually disappeared."

"The emperors of the Han dynasty have demanded the orthodoxy of the Mandate of Heaven and the Son of Heaven, and the Mo family is so ignorant of elevation, the court naturally can't tolerate him." The girl sighed with emotion after hearing this.

"Not bad...... Most of the mechanism techniques inherited by the Mo family were also destroyed in the turmoil of that year, which is really a pity...... Legend has it that the Mohists have three factions: politics, acting, and reasoning, each of which focuses on handling national political affairs, studying the art of institutions, and exhaustively studying the truth of the world. Each of the three factions has a moment order as a token, which is non-attack, Tianzhi, and non-fate. ”

The girl's eyes lit up after hearing this: "Cousin, if you take a closer look at this Tianzhi Order, there must be the inheritance of the Mo family in it!" Their tricks are so powerful, they can't even see the flaws in this box, maybe there is some mechanism that can hide things inside! If we can open it and find the lost ability, it will also be a great merit! ”

Fang Tai was also a little moved, but he still felt that there was no hope, and shook his head and said: "As a token of the inheritance of the Mo family's acting sect, it is normal for this Tianzhi Order to have a corresponding inheritance, and it also just explains the source of the Liu family's technique.

"The Liu family has held this Heavenly Decree for hundreds of years, if there is a secret in it, maybe someone will have cracked it a long time ago, where can we wait."

Having said that, the girl still held the Tianzhi Order in her hand and looked upside down, as if she wanted to split this thing in half with her eyes.

Fang Tai saw that she was obsessed with finding the secret, pouting and frowning, looking particularly cute, and couldn't help but be amused.

The Heavenly Decree flipped back and forth in the girl's hand, but there was still no change.

Fang Tai couldn't persuade the girl who was already on top, so he took care of himself and went around in this secret room, trying to find a way out.

Just walked away a few steps, but heard a "click" sound behind him, followed by the girl's excited shout: "Look! There's a mechanism in there! ”

Fang Tai looked back, only to see that a crack suddenly opened on the Tianzhi Order held by the girl, protruding from a small square surface.

This made Fang Tai also couldn't help but be interested, and asked, "Huh? How did you get it? ”

"I don't know...... And just that, that, in this way, came out! ”

The girl also seems to have stumbled by mistake, and she can't tell what's going on.

Fang Tai took the Heavenly Decree, and after its surface cracked, it could be clearly seen that several horizontal and vertical gaps appeared on its entire body, which were indeed assembled from large and small parts.

Looks like ...... It's like, a different style of ...... Luban lock!

A flash of light flashed in Fang Tai's heart, and he finally remembered a gadget he had touched before, or even made with his own hands.

Once when Fang You was teaching himself the principles of the trick, he said that this Luban lock was the originator of the trick, and it was created by another great craftsman, Lu Ban.

Luban, also known as the public loss class, is also the ancestor of the world's mechanical arts, good at manufacturing all kinds of siege machinery, and once argued with the founder of the Mohist family with a model.

Many of the tools used by today's carpenters, such as saws, planers, and ink fountains, are said to have been created by him.

It is recorded that Lu Ban learned a skill when he traveled around the world, not only limited to institutions and civil engineering, but also Taoism, medicine, feng shui, spells, and charms...... At the same time, he was also the first Yan Master in the world, making the first moving puppet.

In short, there are many legends about Lu Ban, and there are many versions, but what he knows the most is the debate with the Mo family and Lu Ban Suo.

It is rumored that although Lu Ban and Mo Zhai do not agree with each other, due to their common preference and study of the technique, the two jointly wrote a book, which covers all the secrets of the technique at that time, as well as the miscellaneous science that Lu Ban learned.

Mo Zhai did not name Lu Ban on the grounds that he recorded more knowledge of Lu Ban in the book, so he named it "Lu Ban Book".

And the Luban lock is another thing that he has passed down to the world and carpenters all over the world have to learn. Luban lock is a simple mechanism created by Luban in order to educate children and enlighten wisdom, and it is made of a few wooden sticks.

Although the structure is not complicated, it is extremely ingenious and contains a variety of knowledge such as mortise and tenon joints, mathematics, spatial arrangement, and sexagenary branches, which tests eyesight and intelligence.

Especially after the development of later generations, Luban lock has become a general term, and its structure has developed from six wooden strips to nine columns, twelve columns and even more, and the shape has become more boxed, barreled, spherical and other shapes, and even can be combined at will.

It is also often used to make containers for secrecy because of its intractable properties.

So the Tianzhi Order in front of you is really a kind of Luban lock?

Is there a legacy of the Mo family hidden in it?
