Chapter 81 Watch the Moon Rise

Banxia exhaled, put down the "Journey to the West" in her hand, stretched, looked up and looked out the window. The black moon was hanging low in the sky. It looked the same size as the white moon, but much darker in color, almost hidden under the dark blue sky, as if a round hole was opened in the velvet night sky, revealing the deeper universe behind it. The teacher said that the reason it was so dark was because its surface was very rough and not smooth, and most of the sunlight was absorbed and scattered, and could not be reflected into people's eyes.

It was difficult for Banxia to imagine how rough the celestial body was, because even the white moon with its bumpy surface covered with craters could reflect the bright sunlight like a mirror in the night sky. The huge ups and downs that looked like mountains in the eyes of ordinary people would be like some sand on a smooth table top once they were placed on a planetary plane. The black moon was different, it was planetary in size and also had planetary roughness. The teacher's casual doodles on "Journey to the West" indicated that the surface of the black moon had fine, messy, criss-crossing complex lines. This might be the result of her observing the black moon with a telescope in her early years. These lines and gullies were obviously hundreds of kilometers long, and the depressions were bottomless. Banxia inexplicably felt that it was like a huge circuit board, or a huge city covering the entire surface of the planet.

The girl stretched her body vigorously, then stood up and paced back and forth in the room twice.

Her slightly damp hair was draped over her shoulders. She was wearing a loose white T-shirt, black shorts, and plastic slippers. Banxia lifted one foot, balancing on one foot, leaving the slipper on the floor, and moved her white toes back and forth.

Uncle Huang came in through the crack in the door, Banxia bent down, picked it up, and put it on the table.

"BG4MXH, BG4MXH, I'm back." The girl sat back in her chair, picked up the microphone, and pressed PTT. "Let's continue. I'm actually not sure how effective human weapons are against the big eyeballs, because I haven't participated in the battle against them, only the teacher has participated. But if you think about it, you know that we humans lost miserably, and our weapons probably won't be of much use."

"Miss, have you seen the remains of the big eyeball?" Bai Yang asked, "If there are any, we can analyze the effectiveness of the weapon based on the remains. OVER."

"No." Banxia shook her head decisively.

She had never seen the remains of the big eyeball.

She had only seen the living big eyeballs from a distance once when she was very young, and had never seen them again. After the extinction of humans, they disappeared with them.

"It's very strange. There are no remains of big eyes, nor human bodies." Bai Yang was puzzled. "Where are all the people? OVER."

"There are human bodies!" Banxia replied, "Last time I fished for a time capsule in Crescent Lake, I pulled up a skull!"

"Uh... I mean a lot of corpses. After all, all humans in the world are extinct. With a population of seven billion, shouldn't the corpses be piled up into a mountain?" Bai Yang thought for a moment. "There are eight million people in Nanjing alone. Where did all these people go? It's almost an impossible task to destroy the bodies of so many people. OVER."

"Is it impossible?"

"Is it possible?"

"Of course, we can put all the people in sacks and sink them into the Pacific Ocean." Banxia said majestically, "How much area will it take to spread all seven billion people on the bottom of the Pacific Ocean?"

"Let me calculate. If one person sinks upright, he will occupy 0.3 square meters of land. Seven billion people will occupy 2.1 billion square meters. 2.1 billion square meters is 2,100 square kilometers." Bai Yang calculated, "It's about one-third the size of Nanjing... It's not that big. Miss, if you dive under the Pacific Ocean, you might see densely packed corpses standing on the seabed like the Terracotta Warriors. OVER."

The two people's thoughts were quite divergent during their chat. The information the teacher left on "Journey to the West" was limited, so they started to expand outward from the few words on the paper, brainstorming, writing down all the unreasonable ideas, and then sending them all to Zhao Bowen.

Including but not limited to:

Hide the Earth.

Establish a super-large strategic missile defense position.

Build underground cities or underwater cities, and all mankind will move to live underground and underwater.

For the future of all mankind, these two little heads have racked their brains and put in a lot of effort.

But Bai Yang still doesn't know to what extent the threat human weapons can pose to Big Eyes. Tanks and planes, in Banxia's words, are just burnt wreckage on the roadside. The only weapon they can confirm will work is also the most powerful weapon in the hands of humans.

——Nuclear bomb.

"Nuclear bomb." The girl said, "Nuclear bombs are effective against large eyeballs. That's what the teacher said. Do you still remember the nuclear bomb that exploded in Zhenjiang that year?"

"From my perspective, this should be a nuclear bomb that will explode in Zhenjiang in the future," Bai Yang said. "OVER."

"The teacher said that was the most successful action taken by humans to resist the big eyeballs. I thought since she said it was the most successful, the nuclear bomb should work." Banxia said, "The nuclear bomb can threaten the big eyeballs."

"Ugandan chimpanzees?" 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, how can this be a chimpanzee?" Bai Zhen felt very relieved. After all, they were old friends and would always stand on his side.

"This is a baboon." said Wang Ning.

The ridiculously 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 motherboard, keyboard, monitor, camera, amateur radio and other major hardware were all complete. The image signal collected by the camera would be compressed in the Celeron 3150 industrial control motherboard, and then encoded into an audio signal and sent out through 725.

The device responsible for receiving signals in the simulation experiment was the Icom705 borrowed by Bai Zhen. This amateur radio station also played an important role in the previous remote control system construction experiment. 705 is a new radio station, much more digital than the old antique 725. It is connected to the computer to receive and demodulate image signals.

"Check the interface." Wang Ning said, "Pay attention to whether any interface has fallen off."

They used a Hikvision UVC camera connected to the USB 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 mainboard is connected to the microphone of the 725 radio. The sound card is responsible for inputting the crackling audio signal into the radio. The principle and operation of this step are similar to the previous remote control system.

"The only difference is that the PTT port of the microphone needs to be connected to a separate switch, which is responsible for controlling the transmission and reception."

Bai Zhen held a small switch in his hand, which was connected to the PTT interface and ground wire of the 725 radio microphone. When the switch was closed, the circuit was connected, the 725 radio was triggered and started to transmit images. When the switch was opened, the circuit was shorted and the transmission stopped.

11:30 pm.

"November 8, 2019, 11:30 p.m." Wang Ning glanced at his phone, "The first image transmission simulation experiment, all departments are in place!"

Bai Zhen sat in the stairwell outside the door with a small table, a 705 radio and a laptop computer on it, and an antenna.

"Radio station No. 5 in Guaidong is in place for reception!" Bai Zhen shouted.

"Turn 25 and send the radio to position!" Wang Ning shouted.

"Lenovo computer decoding is ready!" Bai Zhen shouted again.

"Celeron industrial control coding is ready!" Wang Ning shouted again.

"Get ready for the two-meter whip!" Bai Zhen shouted again.

"Hikvision, get ready!" Wang Ning shouted again.

"All interfaces of the receiving system are normal!"

"All interfaces of the sending system are normal!"

“The power supply is normal!”

“Power is OK!”

"The wind direction and temperature are normal!"

"The air humidity and oxygen concentration are normal!"

"Storm Red is in position!"

"Cherno Alpha in position!"

The two people shouted out the momentum of a team.

"02 in position!"

"01 in position!"

"Ten seconds to transmit! Five seconds to transmit! 3! 2! 1!" Wang Ning pressed the power button, "Begin transmission!"
