Ban Xia breathed out, put down the "Journey to the West" in his hand, stretched his waist, looked up out of the window, the black moon was hanging low in the sky, it looked the same size as the white moon, but the color was much darker, almost Hidden under the dark blue sky, the velvety night sky seemed to be opened with a round hole, revealing the deeper universe behind. The teacher said that the reason why it is so dark is that its surface is rough and not smooth, and most of the sunlight falls on it. It is absorbed and scattered and cannot be reflected into people's eyes.
It is difficult for Pinellia to imagine how rough the celestial scale is, because even the white moon with uneven surface and craters can reflect bright sunlight like a mirror in the night sky. On a planet-level plane, that is, there are some grains of sand on the smooth table, but the black moon is different, it is the size of a planet level, and it also has the roughness of a planet level. The teacher's scribbles on "Journey to the West" said, The surface of the black moon has fine, messy, criss-cross and complex lines. This may be the result of observing the black moon with a telescope in her early years. These lines and gullies are obviously hundreds of kilometers long, and the depressions are bottomless. Pinellia is inexplicable. It feels like a giant circuit board, or a sprawling city that covers the entire surface of the planet.
The girl stretched her body vigorously, then got up and paced back and forth in the room twice.
Her slightly damp hair is draped over her shoulders. She is wearing a loose white T-shirt and black shorts, and she is stepping on plastic slippers. Ban Xia lifts up one foot and keeps her balance on one foot. She leaves the slippers on the floor, with white toes Move around.
Uncle Huang came in through the crack of the door, Ban Xia bent down to pick it up, and put it on the table.
"bg4mxh, bg4mxh, I'm back." The girl sat back on the chair again, picked up the hand microphone, and pressed ptt, "Let's continue, I don't really know how much human weapons can do to the big eyes, because I don't Participated in the battle against them, only the teacher participated, but after thinking about it, we know that we humans have lost miserably, and our weapons probably won¡¯t be of much use.¡±
"Miss, have you ever seen the wreckage of the big eyeball?" Bai Yang asked, "If there are wreckages, we can analyze the effectiveness of the weapon based on the wreckage, over."
"No." Ban Xia simply shook her head.
She had never seen the remains of the big eyeball.
She only saw living big eyeballs from a distance when she was very young, but she never encountered them again. After the extinction of human beings, they also disappeared.
"It's very strange, there is neither the remains of the big eyeball nor the corpse of a human being." Bai Yang wondered, "Where did everyone go? over."
"There are human corpses!" Ban Xia replied, "Last time I was fishing for a time capsule in Crescent Lake, and I found a skull!"
"UhI mean a large number of corpses. After all, all human beings in the world have been extinct, with a population of seven billion. Shouldn't these corpses be piled up into mountains?" Bai Yang thought for a while, "There are eight million people in Nanjing City alone. Where did it go? It is almost an impossible task to destroy so many people, over."
"Is it impossible?"
"is it possible?"
"Of course, you can put all the people in sacks and sink them into the Pacific Ocean." Ban Xia is magnificent, "How much area does it take to put all the seven billion people in the world on the bottom of the Pacific Ocean?"
"Let me do the math. A person standing upright and sinking will cover an area of ??0.3 square meters. Seven billion people is 2.1 billion square meters, and 2.1 billion square meters is 2,100 square kilometers." Bai Yang calculated, "About one-third The size of Nanjing Cityit¡¯s really not that big, miss, if you dive under the Pacific Ocean, you might see densely packed corpses standing on the bottom of the sea like terracotta warriors, over.¡±
The chatting between the two of them was quite divergent, and the information left by the teacher on "Journey to the West" was limited, so they started to spread out from the few words on the paper, brainstorming, and recorded all the inconspicuous ideas, and then sent them all to the Zhao Bowen.
including but not limited to:
Hide the earth.
Build super-large strategic missile defense positions.
Build underground cities or undersea cities, and all human beings will turn to the bottom and live under the sea.
For the future of all mankind, these two little heads have racked their brains and brains.
But Bai Yang still doesn't know to what extent human weapons can pose a threat to Big Eyeball. Whether it's a tank or an airplane, Ban Xia's mouth is full of burnt wreckage on the roadside. The only weapon they can confirm will work is also The most powerful weapon in human hands-
Nuclear bomb.
"Nuclear bomb." The girl said, "Nuclear bombs are effective for big eyes. This is what the teacher said. Do you still remember the nuclear bomb that exploded in Zhenjiang?"
"From my point of view, it should be a nuclear bomb that explodes in Zhenjiang in the future." Bai Yang said, "over."
"The teacher said that it was the most successful action in the process of resisting the big eyeball. I think since she said it was the most successful, then the nuclear bomb should work." Ban Xia said, "The nuclear bomb can threaten the big eyeball. "

"A Ugandan chimpanzee?" Wang Ning turned his head and glanced at the laptop screen, "Xiao Wen, what you said is wrong. How can this be a chimpanzee?"
"That's right, where is this chimpanzee?" Bai Zhen felt relieved, after all, he was an old friend for many years, and he would always stand by his side.
"This is a baboon." Wang Ning said.
The extremely slow transmission speed of afsk did not dampen the enthusiasm of Bai Zhen and Wang Ning at all. With the help of Huawei communication experts, they successfully completed the construction of the image transmission link on the second-hand 725 tonight. The main board, keyboard, monitor, The camera, amateur radio station, and all major hardware are fully equipped. The image signal collected by the camera will be compressed in the Celeron 3150 industrial control motherboard, and then encoded into an audio signal, and sent out through 725.
In the simulation experiment, the icom705 borrowed by Bai Zhen was responsible for receiving the signal. This amateur radio station also played an important role in the previous remote control system construction experiment. 705 is a new radio station, which is digital compared to the old antique The level is much higher, it is connected to a computer to receive demodulated image signals.
"Check the interface." Wang Ning said, "Pay attention to whether any interface has fallen off."
They use a Hikvision uvc camera, which is connected to the network port of the motherboard.
The camera is the component responsible for signal acquisition. It inputs the image signal into the Celeron 3150 industrial control motherboard, and the image data is compressed and transcoded before being output.
The sound card of the main board is connected to the hand microphone of the 725 radio station, and the sound card is responsible for inputting the audio signal of the sound into the radio station. The principle and operation of this step are similar to the previous remote control system.
"The only difference is that the ptt interface of the hand microphone needs to be connected to a separate switch, which is responsible for controlling the sending and receiving."
Bai Zhen held a small switch in his hand. This switch was connected to the ptt interface of the 725 radio's hand microphone and the ground wire. When the switch was closed, the circuit was connected. The 725 radio was triggered to start transmitting images, and the switch was disconnected. , the loop is shorted and the transmission stops.
Eleven thirty in the evening.
"November 8, 2019, 11:30 pm." Wang Ning glanced at his phone, "The first image transmission simulation experiment, all departments are in place!"
Bai Zhen sat on the stairwell outside the door with a small table, radio station 705 and a laptop, and an antenna.
"Guaidong No. 5 radio station is in place!" Bai Zhen shouted.
"Guai Er Wu radio station is in place!" Wang Ning shouted.
"Lenovo computer is ready to decode!" Bai Zhen shouted again.
"Prepare for Celeron industrial control coding!" Wang Ning shouted again.
"The two-meter whip is ready!" Bai Zhen shouted again.
"Hikvision is ready!" Wang Ning shouted again.
"The interfaces of the receiving system are normal!"
"The interfaces of the sending system are normal!"
"The power supply is normal!"
"The power supply is normal!"
"The wind direction and temperature are normal!"
"The air humidity and oxygen concentration are normal!"
"Storm Crimson is in place!"
"Cherno Alpha is in place!"
The two shouted like a group.
"02 is in place!"
"01 is in place!"
"Transmission countdown ten seconds! Countdown five seconds! 3! 2! 1!" Wang Ning pressed the switch, "Start transmission! ? - Didn't finish reading?
