The stone house proved to be an excellent place to systematically learn the art of mechanics. Mu Wan plunged into it and couldn't extricate herself.

From Room 1 onwards, the tricks are upgraded step by step. The difficulty is also rising. Rooms 1 to 3 are made of wooden mechanisms; From room 4 to room 6, the material has become stone, which is also divided into elementary, intermediate and high levels; In rooms 7 to 9, the materials have been upgraded again, replaced with iron, copper and other metal materials, and the same as the previous one, one level per room.

The former in nine rooms is much the same. Each one has a problem. Mu Wan figured out the unspoken rules: if each level can be cleared within three days, in addition to the key to clear the level, an additional tool will be rewarded; If you can clear the customs within two days, you will be rewarded with one more tool; If you clear the game in one day, the rewards will be even richer. The key to clear the customs, two tools, and three refining materials.

These tools are also medium-grade treasures at worst. Mu Wan was honored to get a fairy-level golden axe in room eight!

Tasting the sweetness, she naturally seized the drip time and tried her best to clear the level in one day - the difficulty is getting bigger and bigger. The duration of trials has also doubled. Even if the space had thirty times the time flow, it would not be easy for her to clear the level in one day.

By chance, she found that the bamboo slips, materials, and tools in the room were moved to the space, and if they were not moved back, they would remain in the space after successfully passing the level.

If you don't take it, you won't take it for nothing. Anyway, after clearing the level, the room will return to its original state. Therefore, every time she enters a new room, the first thing Mu Wan does is to empty the room.

Finally, she passed the test of room nine and used a one-inch purple gold key to open the door of room ten.

The situation inside the door was beyond her imagination.

Room 10 is the largest, but it resembles a snow cave. There are no teaching materials such as bamboo slips, no dazzling array of tools and instruments, and no piles of various materials. A large map hangs on the stone wall facing the door.

Before Mu Wan could take a closer look, a cold female voice sounded: "Trick, tenth layer, the trial begins!" ”

"The Trialist crafts a secret mechanism that teleports him back to the ground, in any shape or material. The time is a month. ”

"The timer begins."

"Submit the task, please give three high-fives."

Mu Wan secretly rejoiced: fortunately, the rooms in front of her were emptied. Otherwise, it will be difficult for a good woman to cook without rice. At this level, what big test did she take?

The only information provided in the room was the large map hanging on the stone wall, and she naturally went over to see what was going on.

Oh, it's a map of this trial site.

It turned out that the hut by the lake was directly above this row of stone layers, with a vertical distance of ten zhang three.

The tenth level of mechanism art is comprehensive design and practical application. After the first nine layers of study, Mu Wan has reached an advanced technical level in terms of mechanism techniques (announced by the cold female voice. Room 1 to Room 3 are apprentices, divided into three levels: elementary, intermediate and high; Rooms 4 to 6 are craftsmen, and they are also divided into elementary, intermediate and high levels; Rooms 7 to 9 are junior, intermediate, and senior technicians, respectively).

The theoretical level and practical ability are not bad, and the only thing lacking is practice. This is the first time she has designed and applied it herself.

Afraid of omissions, Mu Wan used jade slips to burn down the original map. Under the guise of setting up another tent in the room, she entered the space.

In the practice room of the main courtyard, she conjured up the map in the air and conceived it against the drawings.

She had participated in the design and construction of the teleportation array, so it was not that she had no practical experience at all—the teleportation array mainly relied on the power of formations and prohibitions, and the teleportation device she was currently designing mainly used the principle of machinery. Although the principles of the two are different, they can be regarded as different paths, so they can learn from each other.

For example, as with the teleportation array, the first thing she had to determine was the entrance and exit.

The entrance is clear, and it could only be in Room Ten. So, the first question is: where is the export set?

Theoretically, the closer the distance, the less difficult it is. From this point of view, the lake cottage is the best choice.

However, after looking at the map, she realized that the bottom of the lakeside hut was covered with traps - looking at this map, she really broke out in a cold sweat. Any ornament in the room is a trigger door. Among them, there are as many as three death doors! The door of death leads directly to a secret room, and what is inside is not depicted on the map. However, a skull is drawn in the location of this chamber, and the word "death" is marked next to it. The chamber was on the lower right side of the hut, only five feet away.

In addition, there is a death door in room ten. The picture is clearly drawn. There is a chronograph hourglass underneath Room Ten. When all the sand in the hourglass is gone, the Death Door will be triggered. The trialist would have been thrown into the secret room with a skull painted and labeled "Dead".

If you don't succeed, you will become a benevolent!

The Ancient Immortals said pervertedly.

The bottom of the hut is already full of traps, and she has to add another trap without affecting other traps, which is really difficult.

So, the lakeside cottage, it's not appropriate.

The open space in front of the house, the bluestone pavement...... There aren't many mechanisms in these places, but they're not secretive enough.

Choosing and choosing, Mu Wan set her sights on the rockery next to the artificial lake.

There aren't many traps here, and rockeries and the like are the most common bunkers in traps. The only downside is that it's a bit far away. Most of the parts have to be enlarged and thickened, so the special consumable materials.

Mu Wan sighed. She's a quick trick, and she's seriously lacking in practice, and it seems that she can only do this kind of stupid and rough type.

So, the exit was determined, and the rockery was chosen.

The second step is to determine the type of mechanism and produce drawings.

Mu Wan is very self-aware. Her goal was to leave Room Ten safely, not to show off her skill level to the Ancient Immortals of N 10,000 years ago. In fact, she just wants to show off, and there is no one to show off. After the Great War of Immortals and Demons, the Immortal Clan is said to have collectively moved out of the Yanhua Realm.

Coupled with the choice of export, it also determined that she wanted to make a durable mechanism.

So, the silly and bold style continues to walk.

However, the technique is a rigorous art, and it must not be rough. Every detail of the design is based on accurate measurement, rigorous calculation, and reasonable planning.

Mu Wan laid a six-foot square drawing on the floor of the practice room, and lay on it to calculate and draw......

A month later, the drawings came out!

As if sharpening a sword, Mu Wan repeatedly simulated the large-scale teleportation mechanism she designed in her mind, and adjusted some details until she was satisfied.

The third link is the laying of organs.

In the eyes of others, it represents "powerful", "high-end", and "mysterious...... Wait a minute. In fact, it also has an unknown side - dirty, tired and hard.

First of all, turn the drawings into real objects, Mu Wanmao is in the practice room, sawing, splitting, and cutting...... Eighteen kinds of martial arts are all used. The carpenter, the stonemason, and the blacksmith were all hers. It took another month to finally get all the parts out of the machine.

Next, there is the assembly and laying mechanism.

At this stage, digging soil, digging pits, digging holes, etc., are often necessary. Fortunately, Mu Wan, as a true monarch of the void, is a piece of cake for digging a channel.

In order to save as much time as possible, she started with rough assembly in the space. In this way, on the outside, she can be laid out in sections, and then connected and closed.

Even so, it took five days and five nights to get it done.

Finally into the testing session. Mu Wan looked at the big guy she made by hand, and she was full of a sense of accomplishment.

According to the requirements, she can only test it in sections.

The closed beta was very successful, and the results of her mental simulation and deduction were the same.

So far, it has taken a total of seven days.

Mu Wan took a deep breath, put away the tent, stood in the middle of the room, and high-fived him three times.

"Confirm the submission of the task, please give three more high-fives." A cold female voice rang out.

Mu Wan did as she said and high-fived three times.

The cold female voice said again: "Now for the unmanned test, please trigger the mechanism." ”

The so-called unmanned test means that people are outside the mechanism, trigger the mechanism, and make it work. Generally speaking, for the sake of safety, after the mechanism is formed, it is first tested by no one.

As soon as he finished speaking, the entire ceiling lit up, emitting a soft glow.

Although she is very confident in the big guy she has built by herself, Mu Wan is still a little nervous in her heart. Taking a deep breath, she air-pressed the start button with her mana.

"Click, click, click......" came the sound of gears turning from inside the big guy.

Mu Wan released his mana and monitored the whole process.

It took less than five breaths from start to finish, but it felt like more than five years had passed for her.

Unmanned tests were also successful.

The female voice was still so stiff and cold: "Pass." ”

Mu Wan secretly breathed a sigh of relief.

Then, the female voice announced the reward for passing the level: a white crystal spoon, choose one from the ten inheritance jade slips.

Inherit the jade slip! The inheritance of the immortal clan! Mu Wan was so happy that she almost turned her back on it.

The bright light on the ceiling flashed twice. Ten palm-sized white jade slips floated in front of her.

There are no marks on the jade slips such as words or symbols. Outwardly, they are identical.

You can only hit the big luck. Mu Wan grabbed one casually in the air.

When the jade slip arrived, the light flashed, and the other nine were gone.

The female voice sounded again: "Trialist, within ten breaths, leave in the mechanism you made yourself." ”

When Mu Wan heard this, she didn't bother to check the content of the inheritance jade slip, put it into the space, and immediately walked to the entrance of the big guy, and pressed the start button again.

"Click......"

After a few breaths, the mechanism stopped. She pushed open the small stone door in front of her.

It's the rockery out there.

Mu Wan walked out of the agency. The small stone door "horn" sounded, and it closed by itself. She turned around and saw that the small stone gate and the rockery were integrated, and they were completely indistinguishable with the naked eye. However, if you perceive it with your breath, it is easy to notice that the back of the small stone door is empty.

This also echoes the preface of "The First Lecture on Organ Techniques": There is no mechanism in the world that cannot be understood.

It's finally out! Mu Wan smiled, jumped off the rockery, and gently landed on the bluestone path by the lake.

Unbeknownst to him, his body was unstable, and the surrounding scene suddenly distorted.

Immediately afterwards, Mu Wan was kicked out of the trial area.
