Chen Dongran pointed to the right: "Grandpa, if you can see me, burn the paper on the right."
The paper on the right caught fire.
Chen Dongran's grandma came over, and after understanding the situation, she also placed two A4 papers on the window sill: "Old man, where have you been?
It's been several months.
The old woman misses you a little.
Don't tell me, it does still annoy you a little when you are at home.
You have been away for a few months, and I think of all your good things again.
Come back soon.
old man.
By the way, if you can really hear us and see us.
Please let these two pieces of A4 paper burn.
I'm really afraid that it's a coincidence that they want you to burn paper one by one."
After Chen Dongran's grandma finished speaking, the two A4 papers placed on the window sill actually lit up one after another.
Zhang Jinhai knew that this must be a connection. In his previous life, he knew that in addition to ordinary mobile phones, there were also satellite phones. And Mr. Chen was on a very advanced 2-kilometer cube space black-tech spaceship. There must be a way to connect to the satellite phone there.
But in this day and age, there are no satellite phones for civilian use in Shanghai.
Zhang Jinhai wrote a piece of paper to Chen Daoyi:
Mr. Chen:
I'm trying to use my current mobile phone to retrofit a machine that can communicate with satellites.
Study how your spacecraft sends out signals.
If you agree, burn this paper.
The paper caught fire again.
Zhang Jinhai stood up: "Dong Ran, I'm going out to buy a big brother now."
Chen Dongran: "Shall I go with you?"
Zhang Jinhai: "No, I need some tools for installing and dismantling the telephone. Please prepare them."
Zhang Jinhai came to Youyuan Medical Center, No. 108 Pingan Road.
Zhao Jin came forward and said, "Brother, you are finally back. The medical center is almost overcrowded.
Hurry, there are several patients waiting to be treated."
Zhang Jinhai: "I have more urgent matters. Let them wait. Go and buy me a mobile phone. I need it urgently."
Zhao Jin: "I bought it a long time ago. I couldn't find you in the past few months, so I bought a mobile phone. It cost about 30,000 yuan to buy it. It still feels so painful.
I originally planned to give it to you as soon as you come back so that I can contact you easily.
I'll get it for you right away."
Zhao Jin took out the Big Brother box and handed it to Zhang Jinhai: "You come back here as soon as possible to solve the patient's problem. I can't hold it anymore."
Zhang Jinhai: "Tell everyone, I will be here tonight no matter how late I am. I'm leaving."
Zhang Jinhai used the teleportation function to find the electronic components market and purchased enough related accessories according to the biocomputer's prompts.
Teleported to Chen Dongran's house and knocked on the door. Chen Dongran opened the door: "Jin Hai, are you back so soon?"
Zhang Jinhai: "Well, are the tools ready?"
Chen Dongran: "Ready."
Zhang Jinhai took out Mobile Phone, and using the tools already prepared on the coffee table, he quickly opened the most powerful communication tool of this era - Mobile Phone.
I opened the electronic components and accessories I purchased and successfully completed the assembly according to the biocomputer assembly diagram.
Wrote another piece of paper:
Mr. Chen:
I have successfully modified a simple satellite phone.
Now we use high frequency to test link communication.
If you see it, please burn it.
Chen Daoyi has been observing everything happening at home on the "Proximity" spacecraft.
The note written by Zhang Jinhai quickly burned.
Zhang Jinhai turned on the mobile phone: "Mr. Chen, let's start debugging. Find out if there is a point-to-point communication function where you are."
…
After several hours of tossing, Chen Daoyi’s clear voice came from the hands-free handset of the mobile phone: “Jin Hai, Jin Hai, can you hear me?”
Zhang Jinhai replied excitedly: "I can hear it, I can hear it, it's very clear."
Chen Daoyi: "Contact Z08 immediately and tell him that I need his help and ask him to contact me through your phone number."
After Chen Daoyi interrupted communication, Zhang Jinhai contacted Z08 by phone: "Principal Chen invites you to come to his home. I need your help with something.
May I ask when can you come?"
Z08: "Wait for me, half an hour at the earliest."
"good."
Chen Daoyi took the time to familiarize himself with the relevant functions on the 'Proximity' spacecraft.
After Z08 arrived at Chen's house on time, Zhang Jinhai briefly introduced the situation. Zhang Jinhai dialed Chen Daoyi's phone number.
Link number: "Mr. Chen, Z08 is here. He is talking to you."
Z08: "Mr. Chen, what do you need me to do?"
Chen Daoyi: "I am now trapped on the huge spacecraft of the ancient Blue Star civilization 'Proximity', at an altitude of 300,000 kilometers above the ground. Jin Hai should have told you the situation.
You should report this situation urgently and get clear instructions."
Z08: "Okay. Do it right away.
Dong Ran, let me borrow Mr. Chen’s confidential phone number.”
Chen Dongran brought Z08 to Mr. Chen’s study: “Here.”
Chen Dongran withdrew.
Z08 waited for a long time before coming out and contacted Chen Daoyi again: "Mr. Chen, I want you to try every means to get back to the ground first."
After Zhang Jinhai waited for Z08 to leave, he spoke to Chen Daoyi: "Mr. Chen, your way back should be on the pickup spacecraft.
If you do some research, I think he will definitely be able to let you come and go as you please."
Chen Daoyi laughed loudly and said, "Boy, you are really smart."
Zhang Jinhai felt as if he saw Chen Daoyi talking in the living room, but he disappeared again in an instant.
Zhang Jinhai asked Chen Dongran: "Did you just see Mr. Chen in the living room?"
Chen Dongran: "I saw it. Now it's gone.
How is this going?
Could it be that both of us are dazzled?"
Zhang Jinhai asked over the phone: "Mr. Chen, I saw you in the living room just now. Please try the operation again."
Chen Daoyi chuckled and said, "Well, I'm just not very proficient in his operating methods. I was worried about something wrong just now, so after returning home, I immediately returned to the 'Proximity' spacecraft."
Zhang Jinhai said with a smile: "Come back quickly. It's not convenient to communicate with you if you are outside all the time."
Chen Daoyi replied with the word "ok" and ended the call.
Chen Daoyi walked around every cabin of the spaceship again: "It's time to go back."
"The guiding spacecraft will take me back to my home at Shanghai University of Science and Technology." Chen Daoyi controlled the guiding spacecraft with his mind.
Chen Daoyi's mind prompted the spacecraft to issue a prompt: "1 minute to prepare.

Set off!"
Chen Daoyi smelled a familiar scent and opened his eyes: "Jin Hai, Dong Ran, I'm back."
Chen Dongran rushed over at once: "Grandpa, you are finally back."
Chen Dongqiang rushed out of the toy room: "Grandpa, hug me, hug me!"
Chen Daoyi chuckled and bent down: "Come, grandpa hugs you. Where is your grandma?"
Chen Dongqiang jumped down from Chen Daoyi's arms and ran towards the kitchen: "Grandma, come out quickly, grandpa is back."
Grandma smiled and scolded: "You little bastard, you don't make fun of me all day long. Are you feeling uncomfortable or something?"
