"Holy, starry sky, what the hell is this door made of? It's too hard! After working continuously for an hour with an oxygen cutting gun up to 3,900 degrees, Xia Yu had to cry when he saw that only a finger or so had been cut.

What kind of metal is this, it is a high temperature of 3900 degrees, and the high temperature resistance of the single crystal high-temperature alloy blades of the aero engine is only more than 1,000 degrees, but it has been stuck in China for decades......

Xia Yu couldn't help but think about it, it would be much easier to increase the thrust-to-weight ratio of aero engines at that time, and any supersonic cruise would be a small problem. But now this door is a big problem for Xia Yu, according to the starry sky, the personnel life support cabin is connected to the control room, and many key information can only be learned when entering the control room, but according to the current situation, I am afraid that when the astronauts who come to change shifts fly to the moon, this door still cannot be opened, which is still too slow for Xia Yu, who consciously accelerates the understanding of this spacecraft technology in China.

"The hatch of the main control room is made of the same alloy as the ship's shell, which has good thermal conductivity, and most of the temperature when the oxygen is cut has been conducted to the hatch and the surrounding bulkheads." Starry Sky explained: "If you activate the cooling system, Xia Yu, you can't touch it. ”

Xia Yu was helpless when he heard this, so he had to say in his mind: "What should I do, the speed of oxygen cutting is too slow, and I guess I can't blow it up even if I use explosives, can I just watch it live and die?" ”

"Not really." Xingkong said: "At present, the life support ship of the Ledidas has entered an emergency life support state, in order to allow the search and rescue personnel to complete the rescue as soon as possible, the main control room is specially designed with an emergency automatic opening and closing device, that is to say, Xia Yu, you can use the opening and closing device to open the door directly, without cutting and demolition." ”

Didn't you say this earlier?! Xia Yu rolled his eyes and asked, "Where is the opening and closing device?" ”

Under the instructions of the starry sky, Xia Yu found a small box built into the bulkhead next to the hatch, in order to avoid arousing the suspicion of Ivy and others, Xia Yu deliberately asked for a replacement to cut, and then pretended to accidentally touch the flat touch switch on the bulkhead when he got up, and then closed the bulkhead of the small box to reveal an opening, which immediately caused a commotion.

"What is this?" After the initial nervousness, Ivy lowered his rifle and asked.

"It looks like a control panel." Jin Ming stood in front of the opening and closing device, looked at it twice, and said, "Otherwise, it wouldn't be designed next to the hatch." ”

"That's the way it ......," Luo Xiang suddenly interjected, "But this is an alien spaceship, right?" Who knows if there will be any surprises if there is any movement, just like before. ”

Because of Luo Xiang's words, Ivy and Jin Ming suddenly became nervous. You're going to die if you don't speak? Xia Yu complained secretly, but fortunately, Xia Yu still had a way, so he immediately said: "No, this shouldn't be a defense mechanism, you look here." ”

Xia Yu pointed to a polygonal diamond icon on the control panel and said: "We have seen this logo many times before, and some of them have fallen to the ground, you are looking at the diamond-shaped symbol in the middle of the hatch, these two are the same." ”

"That's right, but Captain, what are you trying to say?" Luo Xiang asked.

"I'm trying to say that if this control panel is a defense mechanism, then we've already found an anomaly." Xia Yu said: "But nothing happened, so compared to this thing is a defense agency, I believe that it is an authentication system, Jin Ming, what do you think?" ”

"I think so." Jin Ming, who was mentioned by Xia Yu, pondered for a while and said: "Before the flying saucers that attacked us before began to attack us, I didn't find anything exactly like this one anywhere, and it was too strange to install a defense control system next to the hatch, so I am more inclined to the captain's statement, this is an authentication instrument." ”

Luo Xiang didn't speak, but Ivy was stunned for a moment and said: "Even if this is used to verify identity, we can't use it, God knows what those aliens look like, with big eyes and big heads, and limbs as thin as tree branches?" ”

"I guess it's not the kind of verification method that scans physical features, right?" Hearing that the topic might have deviated to a worse direction, Xia Yu interjected and said: "If it was that kind of scanning method, it is estimated that the alarm should have sounded a long time ago, I am very interested in the changeable diamond shape above, what do you think will happen if we use the same thing to install it?" ”

"Put it on?" When Jin Ming heard this, he immediately stepped forward and took a closer look at the somewhat recessed diamond-shaped logo on the control panel, and then said: "I think I can give it a try, I just picked up an identical one on the way here, I originally wanted to take it back as a souvenir, it seems that it can still be used?" ”

Sure enough, he is specialized in all kinds of mechanical equipment, and his mind is lively for things like machines. Xia Yu was overjoyed, and guided without a trace, he would be able to harvest immediately, much smarter than the two people who could only drive a spaceship and shoot guns, Xia Yu glanced at Luo Xiang and Ivy, and the two immediately shivered inexplicably.

But now Xia Yu didn't have the heart to pay attention to Luo Xiang and Ivy, and said to Jin Ming: "You carry that kind of symbol?" Put it on and try it. ”

"Okay, I'll try." As soon as he said it, Jin Ming turned around and took out a palm-sized, identical-looking polygonal diamond-shaped metal from his toolbox and was about to install it in the recess on the control panel, Luo Xiang immediately became nervous and said, "Wait, what if there is a sudden accident?" ”

When Jin Ming heard this, his hand that had already placed the polygonal diamond sign in the recess was about to be retracted, Xia Yu deliberately accidentally touched Jin Ming when he moved his body, and then Jin Ming directly pressed the sign down, which just happened to fit the control panel.

"Alert!" Luo Xiang screamed nervously, and immediately picked up his rifle and aimed around, Ivy was the same, even Xia Yu pretended to be nervous and half-squatted down, holding the rifle and making a shooting alert. Jin Ming was also nervous by Luo Xiang, but nothing happened after half a sound, which made a few people breathe a sigh of relief and make a false alarm, but at this time, the hatch that had embarrassed Xia Yu and the others for an hour suddenly opened.

PS: I guess there are already brothers who have noticed...... We...... Cavin Bird!! The rhythm can't go up or down, and I've been half-hanging on the number of words, and I want to pause the words, and I've been brewing for a few days! ! Crazy~(-_-#)!
