After a while, the front reported that it was time to reach its destination.

The sand fox was overjoyed, and when he walked up to the team, he saw a rather large natural stone chamber in front of him, and he also saw a lot of stalactites and stone pillars under the light.

But that's not the point, it's an iron carriage housed in the center of the stone chamber, shaped like a giant capsule, with one end of the capsule connected to a metal platform, and the rails below leading to the unknown depths.

"It seems that this is a transportation system excavated from natural karst caves, and this is the first station. Mink said.

"Yes, I just don't know if the driver can still send the car. Shahu breathed a sigh of relief when he saw the iron car, as if he was out of that mysterious danger, and he was still in the mood to make a little joke.

The mink walked over and explored the carriage, first making sure that the carriage itself had no power system, and then probing around the upper and lower corners, and found a bracket under the iron car to press, and the "capsule" was turned over, revealing the cockpit inside.

"Fascinating. Sand Fox praised the mink's tricks in a unique way, although it didn't quite fit the occasion.

The mink turned a deaf ear, walked into the cockpit and first explored the part that was suspected to be a mechanism, the layout in the cockpit was very simple, three rows and three rows of nine fixed metal seats, and then a very simple operating platform, no seat belt, no driver's seat.

The mink beckoned to the other two team leaders, and the sand fox was the first to walk into the carriage and asked, "Have you figured out how to start the train?"

The mink replied, "Call a few people and sit in." ”

"No, mink, you still need to test your skills?" said the wolverine.

"Why don't you just sit down?" said the mink, making a gesture to invite in.

Shahu ignored their daily raising, and directly ordered three people, a third-level attending physician, a third-level special lieutenant and a fourth-level organ division who was second only to mink in this operation, and they were people who originally belonged to the three groups, which were very balanced, and the mink wolverine had no opinion.

It's one thing for the selected team members to carry out orders without any nonsense, and the most important thing is that there is no option to reject orders from superiors in the organization.

The three of them got into the cockpit, closed the hatch, and after a while, they only heard the sound of "bang", and the large capsule car of the small passenger car said that it was a bit exaggerated to say that it was a loaded bullet, and the speed was no less than that of an arrow from the string that shot straight to the end of the track.

"Wonderful!" the mink exclaimed loudly for the first time since going down to the underground palace, "I have been thinking about what the power of the railcar is, I have thought about the potential energy of the spring, the potential energy of gravity, and even the vapor pressure of compressed air, but I never thought that it was actually an electromagnetic catapult! This is thousands of years earlier than the 1988 plan of the US Navy and the Carman Aerospace Company to develop an electromagnetic catapult for aircraft carriers! China is really a magical country." ”

The wolverine asked, "However, it is impossible for these ancients to make a generator." Isn't it time for them to complete the electrical revolution and enter the age of technology?"

Mink said: "There are two explanations, one is that the ancients replaced the generator with other special items, but that kind of item is very scarce, it is impossible to promote, and naturally it cannot form an electrical revolution, and the second is that these Chinese people have found a more complete generator from the lost ancient civilization, just like what we do now." ”

After a minute and a half, a communication came, the three-person advance team arrived safely, the preliminary investigation at the terminal was not in danger, and the iron car had returned.

After another minute and a half, the iron car returned from the depths of the tracks, and the speed slowed down rapidly when it was more than ten meters away from the starting platform.

It's so sophisticated that it's hard to believe it's a millennium ago.

Wolverine said: "I really believe now that there was a higher human civilization thousands of years ago. ”

Fearing that the overload would cause an accident, out of caution, the shuffleboard asked the remaining team members to ride in two rides, five to six at a time, to transport the remaining eleven team members to the finish line.

The second trip to the iron car was naturally accompanied by three captains, which of these three left the team, and the other two were not at ease, they had to be in each other's sight and keep a safe distance in order to be peaceful, which was the way of coexistence and cooperation between predators.

The speed of the iron car is extremely fast, and it is not stable, but considering that its audience is all masters, there is naturally no need to consider safety and comfort, and the sand fox and others are also very human, and after a minute and a half of precision, they successfully arrived at the station and stopped.

The terminal is another natural cave converted into a stone chamber, and Shahu got out of the car and observed the new situation while confirming the map in his mind, establishing a direction and becoming more and more stable in his heart.

Although this road was a bit troublesome, it was indeed smooth enough, not only did it avoid most of the defense organs, including the most troublesome activity dungeon, but also the expected several dangerous areas did not go wrong, and the only danger that the team encountered was the loss of a few team members at the front of the trial road, which was much better than the expected casualties.

The mechanic of the three advance team members who had been prioritized for investigation reported: "The two stations are almost identical, and the inspection has confirmed that there is no killing mechanism." ”

Shahu said: "Well, this is already a core area, and naturally there are no organs that require human lives." ”

In fact, they have not encountered a defense mechanism since they entered the sect, after all, they entered from the trial path of the mysterious sect to assess elite-level disciples, and the blade array that they encountered along the way, including the blade array that made them embarrassed, was just an assessment agency, and the credit of the map in this cannot be ignored, and Shahu was sure again in his heart that the map was right.

After all the 14 players had arrived at the roll call, the sand fox led the way to a square the size of four basketball courts in less than ten minutes, following the guidance of the map.

The square is large and high, and the Qianmen Square of the trial site is different from the six sides of the bronze metal wall, like a bronze sealed big iron box, the front and back are lined with dense bronze beast heads, there are jackals, tigers and leopards, there are moose, cattle and sheep, for a time everyone seems to be surrounded by a group of beasts, shuddering.

There were engineers in the team who were highly skilled in materials, and they had already seen that it was not bronze in the square of the trial ground, and if it weren't for the time now, they would have pounced on it and tried to cut a piece and take it away.

"Here we are, this is the final obstacle to the central control room, mink, look at your magic. Sand Fox pointed to the bronze doorway at the end of the square, which was not inferior to the trial ground.

The mink didn't say much, went straight to the northwest corner of the square, probed for more than ten minutes, and then had an eyebrow, grabbed the bite ring of a bronze beast head shaped like a tiger and leopard on the stone wall, slowly pulled it clockwise twice, listened carefully to the sound, and pulled it back and forth a few times, and the mink pulled it down suddenly, and the chin of the beast head was pulled down, revealing a hexagonal groove.

The other two captains and some other team members who are proficient in the art of the mechanism said in their hearts almost at the same time: "Although this mechanism is not very clever, if you don't know it in advance, who knows that this little bronze beast head hides a mystery, there are at least 10,000 bronze beast heads in this hall, and there is no room for tricks, it is the most clever stupid method, and the mink must know the approximate location in advance." ”

The mink took out a bronze medal with a six-pointed star from the inner pocket and embedded it tightly.

Shahu secretly thought: "It turns out that the relevant information and keys of the central control room will be handed over to the mink, and the map route will be told to me, so that we can each grasp part of the information, cooperate with each other and check and balance each other, no one can do anything without it, what a good means." This is called a three-legged stand, no, it is a tripartite balance. ”

glanced at the wolverine without a trace, and said secretly: "This guy looks rude, but in fact he is treacherous, and he can't be underestimated. ”

Shahu remembered a thousand things in his heart, but his face was not full of clouds, while recalling whether his words and deeds along the way were inappropriate, and on the other hand, he quietly suppressed that little bit of caution by the means above.

Seeing that victory was in sight, he had a feeling that the storm was coming.

The bronze gate opened slowly, and there was a slight roar at first, but it was immediately silent, this is a giant gate more than ten meters high, not to mention millions of catties!

The team members who are familiar with the mechanism know that the larger the mechanism, the longer the mechanism is placed from the silence for a long time to the sudden activation of the sound is very normal, this kind of big scene is a test of the technical level, the more bright the movement, the more superb the skill, but this bronze giant door is silent except for the roar at the beginning, and the first little sound is just a thousand years have not been started!

What a masterful craftsmanship this is, can modern society do it?

On the opposite side of the giant gate is not a central control room, but an empty bronze secret room, if there is a large bronze sealed iron box outside the door, then this is a pure bronze cage.

"This mechanical lift is the only way to get to the central control room, so let's go inside," Shahu explained. After that, he was the first to enter, and the other two captains and the team members followed.

The sand fox pulled down the only brake on the bronze wall, and the elevator descended steadily, although the speed was not as fast as the modern elevator, but it was stable enough.

After a short time to land, the car door opened left and right, and the central control room finally removed all protection from the newlywed husband like a shy bride with two infatuated brides.

What unfolded in front of them was a huge hall with a sense of science fiction and ancient Chinese civilization, and a bronze corridor of less than six meters between the lifting shafts.

The mink walked into it as soon as it went, and as skillfully instructed the team members to operate the information and gates in various places, it automatically entered the role of commander.

Shahu didn't care about him, first ordered his subordinates to notify the team members who stayed in place to come, and then reminded the mink to remove the mechanism along the way, so that the rest of the team members could come over smoothly, and then looked around at the central control room that had gone through a lot of hardships.

This hall is cylindrical as a whole, tens of meters in size, more than ten meters high, there are complex gear sets on it are running on it, there are countless points of light dotted on the metal wall on the wall, come closer to see that it is a glowing crystal inlaid on the wall, which is also mixed with a lot of crystal bi the size of a copper mirror, which can actually see the bright green layout of a certain hall, and the control table below is full of various styles of information such as various lever turntables.
