"Where is the password input pad? Take me to see it?"

"It's at the bottom of the gate. Follow me."

The three dragged the toolbox and walked down along the edge of the gate. When they were about two meters away from the bottom edge of the gate, they finally found the password input keyboard that Xie Duanyang mentioned. Qiao Ruida walked closer, squatted down, and took a closer look with the help of the light on the space suit. It is not quite accurate to call this thing a password input keyboard. At least there are no obvious physical buttons. It is just a black square object protruding from the plane of the gate. It is the size of two palms and has a relatively smooth surface. There are some strange symbols marked on it according to the 16-square grid. The specific meaning is unknown. If you have to find a similar one from human creations, it is probably similar to the touch password keyboard of some smart door locks.

Qiao Ruida randomly tapped the keyboard a few times with his fingers. There was no light, no screen display, and no response. "What is the text marked here? Have you asked an expert to take a look?"

"There is serious interference with electronic products here, so we can only draw these symbols with pen and paper, transmit them back to Earth, and ask experts to analyze them. We found several experts and professors who study ancient characters, and the answer they gave was that there were too few samples and they could not decipher them."

"Well, I took it for granted. It's normal that an alien language that no one has ever seen cannot be deciphered."

Qiao Ruida thought about it and decided to start with the keyboard to find a way to open the door. He opened the system panel, found the camera function, used his eyes as a camera, took a picture of the keyboard, and then activated the analysis skill for the photo. The next moment, a large number of design drawings, circuit diagrams, material preparation information, and processing methods flooded into his mind. Perhaps the technology tree selected by the aliens is completely different from that of humans on Earth, so the information obtained from this analysis is particularly large. A small touch password keyboard contains more than 30 new materials, more than a dozen electronic devices that have never been seen before, and three new processing technologies. It can be said that it is full of dry goods and has a great harvest.

This small keyboard actually integrates three ways to open the door. The first one is quite obvious, that is, input the password, and the door can be opened if the verification is correct. The second one is to scan the face and verify the identity, and the door can be opened if it meets the requirements. The third one is more abstract, and the door can only be opened after the genetic code verification. If this access control system works normally, Qiao Ruida and others can only try to enter the password over and over again to open the door. Don't even think about the latter two ways of opening the door. There is a huge gap between aliens and earthlings, and their facial shapes and genetic codes cannot be similar.

Unfortunately, this keyboard is not working properly now, and Qiao Ruida and his team didn't even have the opportunity to try and input the password repeatedly. This analysis also found the reason why the password input keyboard could not be used, that is, there was a problem with the power input line of the entire gate. There was no electricity at all, so it would be strange if there was any response.

The way to open the door by entering the password is blocked, so we can only find other ways to open the door. From the previous detection results, the entire alien spacecraft has only this one door, and its importance is self-evident. Such an important entrance and exit channel cannot be completely controlled by an electric access control system. If the circuit fails one day, wouldn’t all the crew members be locked inside? Therefore, this door must have a backup way to open the door, and it is likely to be a mechanical or hydraulic way to open the door, rather than relying on electric control.

In order to find the last possible way to open the door, Qiao Ruida walked around the edge of the entire door, but no matter where he went, it was flat, and he didn't find any special signs or protrusions. He also tried to take a photo of the door and analyze it, but the result was "the object was not photographed completely, and the analysis failed." It seems that only by taking a complete photo of the door can the analysis be performed and the fourth possible way to open the door be found.

It is not so easy to take a complete photo of the gate. The size of this gate is really too big, with a width of ten meters and a height of twenty meters. With such a large force, if you want to enter the whole gate, you must be far enough away to shoot. After all, this is more than a hundred meters underground, and there is frozen lunar soil and lunar rock next to it. It is not easy to open up a space more than two meters high above the gate. It is quite difficult to continue to open up a huge space for panoramic photos. It is basically impossible to compress the lunar soil alone, unless you make great efforts to move the nearby lunar soil and lunar rocks out and throw them somewhere else, but the project is too large and the construction time is too long, so it is basically impossible to achieve.

In fact, the best solution is to dig a big hole at the South Pole of the Moon and get the alien spacecraft out as a whole. At that time, it will be no problem to shoot the entire gate or even the entire spacecraft. However, the alien spacecraft is of great concern, so it is better not to expose it to the public in the early stage of excavation. Besides, the overall excavation is extremely difficult to construct and the amount of earthwork is too huge. It is simply not something that Qiao Ruida and his astronauts and a few lunar rovers can accomplish.

Since it is impossible to take a complete photo and it is impossible to fully excavate, we can only think of other ways. Dividing the gate into several areas, taking partial photos, and then stitching them together into a complete photo is a good solution. I just don’t know if the system album supports the multi-photo stitching function. Qiao Ruida took action immediately and divided the entire gate into fifty areas, numbered the photos in turn, and saved them in the same folder. Then he opened the album with his mind, checked fifty photos at a time, and silently thought about stitching the photos. The success or failure of the matter depends on this one move.

While Qiao Ruida was taking photos, Xie Duanyang and Zhou Xiaobo were not idle either. They opened the toolbox, took out various cutting tools they had just brought from Earth, and tried to break the door. As a result, they changed more than a dozen tools, but the alloy door remained intact. Apart from a few scratches and a few black spots, there was no more work. Not to mention making a hole in the door, even getting a little debris and conducting material analysis was difficult.

Qiao Ruida did not expect that the first time he tried to stitch photos in the system, he would succeed. Fifty partial photos were stitched together to form a complete photo of the alien spaceship door. Then he could not wait to start the analysis skill. The amount of information obtained this time was also huge, including the design drawings of the door, material analysis, production methods, processing plans, assembly plans, etc. The parameters of several doors caught Qiao Ruida's attention. The thickness of the main body of the door exceeded two meters, the surface hardness exceeded 9, the yield strength exceeded 5500MPa, and it was resistant to high temperature, low temperature, wear and corrosion. With such a powerful door, it is no wonder that Xie Duanyang tried so many cutting tools but could not do anything with it.

In addition, through this analysis, Qiao Ruida also found a hidden fourth method of opening the door, and it is a purely mechanical method of opening the door. The door can be opened regardless of whether there is power supply or not. Unexpectedly, this door-opening mechanism is not installed on the door, but on the bulkhead five meters away from the edge of the door, and is covered by a lid. The material of the lid is exactly the same as the surrounding bulkhead, and the processing precision is also high enough. The gap between the lid and the bulkhead is very small, and it cannot be found without careful observation.

"Old Xie, Brother Bo, stop it. I found a way to open the door." Qiao Ruida turned on the communicator on his space suit and called out to Xie Duanyang and Zhou Xiaobo to stop.

"What? You found a way to open the door, Mr. Qiao, are you telling the truth?"

"Mr. Qiao, you are kidding. We have come down here several times and tried dozens of demolition tools, but we still can't do anything about this door. Mr. Qiao, you have been down here for less than an hour without using any tools. You just walked around the door twice, looked around, and found a way to open it. Don't be so exaggerated."

"Hehe, this is because you didn't observe carefully, or your thinking is limited. Who said that the door opening plan always falls on the door, so it can't be outside the door?"

"The method to open the door is outside the gate. What does this mean? Why didn't I understand it?" "Come here, look here, see this hexagonal cover? Open it, and the mechanism to open the gate is below." Qiao Ruida walked to a place five meters away from the edge of the gate, pointed to a hexagon on the wall of the spacecraft, similar to a patch, and said.

Xie Duanyang and the other person walked over to Qiao Ruida, squatted down, and looked carefully under the light before they found the hexagonal lid that Qiao Ruida mentioned.

"Is this actually a lid? It's too subtle. You can't find it without careful observation." Xie Duanyang took a small hammer and knocked on the lid and the surrounding bulkheads to feel the vibration frequency. He analyzed, "You know what, the feedback from knocking on the hexagon is really different from that on the surrounding bulkheads. Subjectively judging, the back of this lid is likely to be hollow."

"This hexagonal lid doesn't have a handle or anything, and it fits so tightly with the surrounding bulkheads. How do you open it?"

"I remember that the previous detection report said that the material of this bulkhead is a super alloy containing iron. Since there is iron, it can naturally be attracted by magnets. Do we have a strong magnet among the tools we brought? We can just find one and suck it out directly."

"Strong magnets? I remember there was a strong Ru-Fe-B magnet. It was used to absorb cutting powder for material analysis. Let me look for it."

Xie Duanyang returned to the three open toolboxes and searched around. He soon found a silver-white magnet the size of a baby's fist with a ring on it, which was just right for tying a rope to assist in exerting force. Xie Duanyang took the strong magnet with the rope tied to it, returned to Qiao Ruida, and put it down at the position of the hexagonal lid. With a "click", the two were tightly sucked together, and the sound was converted into a vibration wave, which was transmitted to the feet of the three people through the cabin wall. The feeling was quite obvious. Xie Duanyang tried to pull the rope, but the magnet and the lid did not move at all. Obviously, the suction force of the magnet was strong enough and the fit was tight enough. At the same time, it also showed that this hexagonal lid was not so easy to open, and more force must be applied. Xie Duanyang turned on the power assist system of the extravehicular space suit and pulled the rope again. This time the hexagonal lid finally responded, and it turned to the right and slowly turned over, revealing a bucket-sized space behind it and a handle connected to a rope of unknown material.

"Mr. Qiao really found the right place. There really is something behind this lid!"

"A handle and a metal-like rope extending into the interior of the spacecraft. Are we supposed to hold the handle and pull the rope out?"

"That should be the case. Let me give it a try. I wonder if this mechanical structure has rusted after tens of thousands of years. I wonder if it can still be used."

"We'll know after we give it a try. I think it shouldn't be a big problem. Haven't you seen that all the spacecraft hulls we've inspected have no rust at all? It's obvious that this unknown civilization has very advanced metallurgical technology and has solved the rust problem long ago."

Zhua Xiaobo bent down and grabbed the metal handle, pulling it out with force. At the beginning, it was a bit stuck and required a lot of strength to pull it. Later, it became light and easy, and it was no problem to jog while pulling the rope. As the metal rope was pulled longer and longer, there was a clear vibration inside the cabin wall, which was transmitted all the way to the cabin door, and the vibration became more and more obvious. When the metal rope was pulled out for more than 50 meters, the metal door finally moved and slid upward for more than 20 centimeters. At the bottom of the door, a dark gap was revealed. An unknown gas leaked out from the gap, and the moon dust was flying everywhere, blocking the sight of the three people.

"It's working. The door has opened a crack. Let's keep working and continue pulling the rope out."

Qiao Ruida personally helped Zhou Xiaobo pull the rope. When the metal rope was pulled out for hundreds of meters, the door had slid upwards for more than two meters, revealing a gap that was large enough for three people to enter and exit. The unknown air also stopped leaking, and it was unknown whether it had finished spraying or was blocked by something.

"Commander, the gate is now open more than two meters, which is enough for us to enter and exit. Do we need to continue pulling the rope?" Zhou Xiaobo asked.

"Loosen the rope a bit and see if the door has a locking mechanism to see if it will fall back. If it won't fall back, just keep it as it is now."

Qiao Ruida and Zhua Xiaobo loosened the rope as instructed. The rope retracted less than a meter and then stopped, and the gate did not fall back again.

"Good, the door is stuck and won't fall back. Find our safety ropes and rappelling equipment and prepare to enter the alien spacecraft to explore."

Xie Duanyang connected with the ground and reported the good news that the door of the alien spacecraft was successfully opened. After the door was opened, the electromagnetic interference was significantly strengthened, neutrino communication was intermittent, phone calls were stuck, and video images could not be transmitted at all. No one expected that the electromagnetic interference would continue to strengthen, and the Earth-Moon communication would be unsustainable. As a result, the experts and professors summoned by the Earth Flight Control Center could not help at all, and Qiao Ruida and the other two could only play freely. (End of this chapter)
