"The beacon of the universe?"

Ye Zhou pondered and repeated Lin Ling's words, and he quickly understood the other party's meaning.

She wanted to use the most primitive electromagnetic wave broadcast method to transmit information, and then let other civilizations spread gradually in the form of "beacon fire" until the information spreads to the entire universe.

But the problem is that this propagation is still too slow.

On the cosmic scale, the propagation of electromagnetic waves is in units of ten thousand years, and the speed of the earth's destruction under the impact of adjacent dimensions is calculated from the moon.

According to optimistic estimates, from now on, from the beginning to the complete destruction of the earth in the adjacent dimension, it is estimated that there will be only 600 months left. In such a short time, the electromagnetic waves cannot even get out of the Orion arm of the Milky Way.

Thinking of this, he sighed and said:

"No, the speed is too slow and it cannot meet our requirements."

"It seems that this plan is still too far away and we cannot devote too much energy to this direction."

"The most important thing now is to speed up the technology change as soon as possible."

"It is better to seek oneself than to seek others..."

After pausing for a moment, Ye Zhou continued to ask:

"How are you there? Are there any breakthroughs in theoretical research on quantum ghosts?"

Lin Ling shook his head and replied:

"No. The current direction has been gathered on string theory. If string theory does not make any breakthroughs, it will be difficult for us to explore further."

"However, there are still progress in application. At least we can stabilize the quantum correctly. This technology is still very good for communication."

"Didn't there be any new connection with that quantum ghost?"

"No, the other party probably hasn't recovered from the last collapse---I don't know if it can be recovered."

Lin Ling's tone revealed deep concerns. After all, judging from the current situation, the fate of the so-called "quantum ghost" is her future destiny. If the other party disappears, it means that she will be annihilated at a certain point in time.

This is definitely not an easy thing to accept.

Seeing her expression, Ye Zhou comforted:

"Don't think so much. We haven't studied the quantum field myself and the causes and traits of quantum ghosts are not clear. Maybe it is not a probabilistic cloud form at all?"

"Have you seen the superbody? Maybe you may not necessarily become Scarlett in the future."

Lin Ling laughed, stood up from the sofa, moved the display screen on the coffee table to the desk again, and then clapped his hands and said:

"Okay, it's time for me to go back to bed. What do you say, let's go together?"

The residences arranged by Chen Hao for the two were all within the Huawu Academy campus. When they returned from the office, they were on the way. Occasionally, when the time for get off work was approaching, the two often walked home together, which was one of the reasons why their relationship was gradually getting closer.

Ye Zhou looked at the notebook he drew in a mess on the coffee table, and after thinking for a while, he stood up.

After some communication, he had discovered that the cosmic broadcasting plan was not as simple as his intuition at the beginning. It was meaningless to spend energy now, so it would be better to go back and have a good rest.

"Let's go, go back first, the broadcasting matter...I'll think about it again."

While speaking, he turned off the office lights and walked out of the Huayuan Building with Lin Ling.

It was late autumn and winter was about to begin. Even in Shu, the night wind was so cold that it was so cold. Lin Ling rubbed his hands and said with some emotion:

“A few years ago, I saw it on the news that the summer was the coolest summer in the next decade – due to global warming.”

"I was quite worried at that time, if the global warming trends really continued to worsen, would we have to face more problems caused by extreme climates."

"It seems that it's not just me, but everyone is wrong."

After a few seconds of pause, she continued:

"Maybe in another ten years, everyone will hope that the weather will be hotter and hotter."

Ye Zhou nodded silently. He knew that Lin Ling was talking about the impact of adjacent dimensional invasion on global temperature. When adjacent dimensional Tongda appeared on a large scale, the average temperature on the entire earth would drop by more than 10 degrees.

At that time, there will probably be frequent scenes of snow falling in June in Shu.

"This is also impossible. The speed of our energy technology development is impossible to catch up with the speed of the expansion of adjacent dimensions. There will always be a difficult period."

"However, our efforts are to shorten this difficult period."

"Even if it is only shortened from 10 years to 9 years, and reflected to ordinary people, it is a huge progress."

Lin Ling nodded, holding a dry wooden strip pulled out of the flowerbed in her hand, and continued to ask while shaking it unconsciously:

"If the temperature really drops so much, can our food last?"

Ye Zhou roughly estimated it in his mind, and then replied:

"At present, our grain storage is probably enough for the whole country to maintain it for three years without any grain output. This is already a limit number. If there are too many, production will not be a problem, but neither the storage cost nor the pressure of fiscal funds can hold on."

"So, our buffer period is actually these three years--or these three years of food."

"After the temperature drops, there will be a gap in our food supply every year. According to the estimates of the Academy of Agricultural Sciences, the maximum gap will even reach more than 50%, and this gap must be supplemented by stored grain."

"If you make up for 30% per year on average, three years of grain storage can support 10 years. We must return to equilibrium within this decade - no matter how harsh the conditions are at that time."

"So this is the fundamental purpose of the Tongtianhe project? I have always heard voices saying that the Tongtianhe project is unnecessary. Using the vast mountains in the south to develop terrace planting, the area that can be utilized will not be smaller than that of the northwest region."

"That's because they did not consider the environmental ecology and soil carrying capacity. Experts from the Academy of Agricultural Sciences are not for a good meal. This strategy has been proposed and calculated long ago. According to the data, even if we turn the entire south into terraces, it is not enough to feed everyone."

"Sodium heat, soil, ecology, and even water sources are all problems."

"Someone has proposed a more extreme solution--they want to knock down there directly."

"Can you fight?"

A look of hesitation flashed in Lin Ling's eyes. She did not expect war, but if the solution to the problem of "let the Chinese live" is only war, she would use her own strength to do her best.

"So what can I do if I fight? I can't kill all their people, right? This is actually a false proposition, the real plan, or agricultural cooperation."

"When I went to Hailan before, I met a little girl named Xu Lei at the Academy of Agricultural Sciences. Now she is in Punjab, working on digital farmland and high-yield wheat projects. The progress is very good. So far this year, the wheat production in Punjab has increased by 20%.

"If you continue to advance, it will be no problem to double within three years."

"So exaggerated?"

Lin Ling opened his mouth wide in surprise.

"It's not too exaggerated. The result is not because we are so powerful, but because the people in Yindu are too naughty."

Hearing Ye Zhou's joke, Lin Ling smiled silently, and the two walked forward shoulder to shoulder. After a long time, Lin Ling continued to ask:

"What about Tongtianhe Project? What's the progress now?"

Ye Zhou took out his cell phone from his pocket, opened the email address and flipped through it for a moment and said:

"From the report, they have basically completed the preliminary line survey and planning. The next step is to start river renovation and pump station site selection."

"This is the most difficult part of the entire project, I hope they...all the best."
