There is an experimental field for mechanics next to the main building of No. 72 Street, but it is not located on the ground, although the chaotic area seems to have far more area than the carrying capacity of the population, but except for the seven major urban areas, they are all vast deserts, so the urban area is rich in memory, like the large-scale auction of the experimental arena fighting arena, which occupies a huge area, and generally only sets up a gorgeous storefront in the eye-catching place of the city as an entrance passage, and the real venue is below.

The Mechanic Experimental Field is actually also called the Mechanics Guild, and it can provide a venue for registered Mechanics to research and manufacture Mechanic equipment at a discount.

After all, the experimental field is only suitable for mechanics, and mechanics rarely go out because of the research and design of mechanics, so the experimental field of mechanics does not need to be decorated with popular ornateness, just like a piece of marble inlaid in the corner of the huge main building, and only uses a huge metal beast mouth as a gimmick at the position of the door to attract passers-by. However, the fangs of this beast's mouth are the length of an adult's arm, exuding a metallic luster, which makes Xi Yixiao wonder what kind of existence its body is.

Sha Ning walked in front and took Xi Yixiao in, as if he noticed his interest in this beast's mouth, and introduced in a cold voice: "This is a part of a real super machine beast after it was destroyed by the strong, it is very complete, it was bought by the guild, the core components are used for research, and the mouth attack parts seem to be only ornamental, so they can only be used to support the scene." ”

These super trap beasts that were destroyed by the battle but left the core components are very tempting for low-level traps, but unfortunately the real core components are just like the internal strength trend of the warrior, which is the real key, and such cores are generally installed with unique self-destruct procedures, and the core components of the organs can rarely appear. Therefore, although there are often so-called trap beasts for sale on the market, there are few core components, unless it is like this kind of Trap Master Guild, which can obtain relatively complete parts through a unique method, but due to the huge loss, the gains usually outweigh the losses, and it can only be regarded as a gimmick to attract popularity.

After entering, there was a crystal counter with low transparency, with many wooden tokens on it, and behind the counter sat an old man with bad eyes, pushing his glasses and looking at a book laboriously.

Xi Yixiao found that Cha Ning didn't pay attention to the old man, but walked straight by, so he had to bow slightly, and then followed.

The store is not big, there is only a bare metal wall inside, I saw that I didn't speak, I took out a bronze token and shook it in front of the wall, and then there was a slight click, and there was a circle of rotating half-arc cracks on the metal wall where there was no gap, and slowly opened to reveal a passage that extended straight down, and then walked in without hesitation.

There was a slight click behind me as the wall closed again.

The passage is not big, but it is large enough for the two of them to walk side by side, and there is a crystal pipe that extends straight above the head and on each side, and inside is the secret luminous liquid of the mechanism that emits a faint light, the light is not strong enough, but it is enough for people to see the metal staircase under their feet.

The passage was long, but it felt like the air around them was still fresh, and after about a quarter of an hour, the two of them walked out as soon as they lit up.

There is still a passage in front of him, but it extends left and right, and Cha Ning walked to the right familiarly, and Xi Yixiao hurriedly followed.

The passage is very large, enough for a two- or three-foot machine beast to barely pass, and the four corners of the ground and ceiling on both sides are inlaid with crystal lamps that are the thickness of a child's arm, which seems to be fragile, but in fact it is plated with a layer of secret enhancement liquid of the machine master, which is difficult to damage with ordinary heavy blows.

On both sides, there was a huge black door as high as the wall, and the number was written on the door in luminous liquid.

"This is the Mechanic's Experimental Field, isn't it unexpected?" Cha Ning seemed to be relieved of the cold as soon as he came here, although it was still cold, he intended to introduce Xi Yixiao.

Through understanding, I realized that the experimental field is not a huge field, but composed of these huge rooms in front of me, the inside is larger and wider than the outside, because the mechanics are all good at studying all their lives, so the personality is somewhat withdrawn, unless she must broaden her horizons through experience, it is difficult to get along with others, let alone like to be lively. Therefore, the experimental field is actually a structure similar to the residential floor of the main building, but the structure inside is usually the type of research and experiment of the mechanic.

There are thousands of such rooms, covering an area of nearly a quarter of the floor area. However, it is said that the Black Court, which specializes in black market trading, is almost an underground world, covering an area of nearly an entire city block.

However, there are actually ten blocks of places like this, and there are only nine in the entire Sixth District, and there are usually dozens of storefronts on the ground that serve as passageways, and it takes a long walk to get there.

"This should have left the unit on Seventy-second Street, right?" Xi Yixiao couldn't help but sigh.

"Of course not, you must know that according to the area of the block, this street is hundreds of kilometers square, even if we want to cross the area at the fastest speed through the inclined distance, we have to walk for an hour! The underground world is actually the same as the ground world, the cross-street world is surrounded by a circle according to the nine-square grid, the difference is that it is at different depths. The front looks straight, and when you reach Seventy-one Street, you have to turn left into Seventy-fourth Street!" said as he walked forward.

On the map, the edge of the desert where the sixth district is located happens to be an area of thousands of kilometers square, because the builders originally built eight middle-level streets with the central main street as the center of the nine-square grid, and then built 8,972 peripheral streets along the small nine-square grid with the eight secondary main streets as the center of the main street, each with roughly the same area. The street number is arranged at the beginning of the sequence with the 8th Street in Zhongwei, and the Central Main Street is set up in the 0th to 9th Street due to the convenience of administrative management, and the No. 80 Street is crossed in the number, taking the meaning of Tianji as the 81st Street, thus setting the pattern division of the 6th District unchanged for 10,000 years.

After walking for about a few hundred feet, they also found a passage similar to the one they used to enter, which should be connected to the storefront on the ground.

Finally listened in front of a door, Sha Ning shook the token in front of the door again, and the two walked in.

Really as Sha Ning said, the room can no longer be called a room, the length and width are more than ten zhang, the height is four zhang, there are many machine equipment placed in the corner of the wall, there are huge shelves on both sides, and many materials are placed in different categories.

There are two layers of crystal passages with a width of one zhang and high transparency connected to each other, and the second layer of passages is centered on the central open space with the same dozen strange-shaped mechanism equipment.

And in the central position, in the huge metal cage, it should be the reason why he came this time, three silver-level trap beasts!

The appearance of a wild wolf, a huge body one foot high and two feet long, bright silver metal skin, seamless joints that shimmer with a great sense of strength, thick limbs, bloodthirsty fangs and sharp claws, no eyes, because there is no need, that position is the cannon muzzle of two black holes, with the dazzling appearance, it is actually a little throbbing......
