It was a quiet afternoon when Di Fengyi came to the Garden of Eden with the video sent by Mars.

He saw Jiang Yu lying halfway under the shade of the tree, staring at the fishing rod not far away.

Yang Dong sat beside Jiang Yu reading a book.

Strangely, neither of them spoke, but the atmosphere between them did not seem cold at all.

That sense of tranquility and freedom seemed to cleanse all the impetuousness in Di Fengyi's heart.

If it weren't for love, Di Fengyi would not be willing to disturb Jiang Yu's tranquility.

He has been by Jiang Yu's side, knowing that Jiang Yu has paid too much for the plan to face the wall, so Jiang Yu should have had a rest long ago.

But, the rest has come to an end.

Di Fengyi walked over and was about to speak, but Jiang Yu said first: "Wait, let me catch another fish."

Di Fengyi nodded and returned to the wooden house to wait for Jiang Yu.

Soon, the fishing rod shook, Jiang Yu began to retract the rod, and Yang Dong helped him catch the fish.

Jiang Yu untied the fish hook, looked at the lively fish and smiled and said, "I probably won't be able to eat it at night, let it go."

Yang Dong nodded and handed the fishing net to Jiang Yu.

Jiang Yu walked into the lake to release animals and said, "I'm going to work."

"I'm going to hibernate too," Yang Dong smiled and said, "I've been very happy these days. There's nothing to regret. Please treat this time as a good time for us to be together."

Jiang Yu watched the fish return to the water and swam away quickly: "It's precious because it's short."

After saying that, he returned to the shore, took Yang Dong's hand and returned to the wooden house, quickly packed his luggage, and left the paradise that night.

On the way back to China, Jiang Yu watched the video sent back from Mars.

...

The background of the video is the not very wide activity room in the Mars base.

The walls of the activity room and the colors of all applied objects are cold tones, and the whole environment looks a bit cold.

You Haoming was the first to speak: "We have been searching for the area where we send out the wisdom signal for six months, but we still found nothing."

They have tried almost all the methods they can think of, including simple excavation, drilling, and even blasting, as well as detection of various precision instruments.

But nothing was found.

Lorfo also prayed for more than two hours and asked God to help them, but unfortunately God did not appear.

You Haoming continued: "The other party has only reserved about ten days for us. Now let's discuss whether there are any other search methods? Or any new interpretation of the prompts given by the other party before?"

Sitting on the left, the short hair was a bit greasy, and the face was tired: "Xichang guessed that the other party was the origin of carbon-based life, and their body structure may be far beyond our expectations!

"But there is another possibility, what if the other party is not a carbon-based life, but a silicon-based life?

“Is it a gaseous life that we may not see with our naked eyes?

"Or, they have separated themselves from the living body and are only left with a group of conscious thinking?"

The unshaven Bearded Beshkv had a little red eyes and looked like he had not had a good rest. He waved his hand and said:

"No matter what creature they are, we can always observe the device that emits electromagnetic wave signals to the earth!"

Theodore disagreed: "The other party's technology may have exceeded our imagination. Just like when the other party sent a message to the earth for the second time, we mobilized all the satellites and did not find their sending equipment.

"So we cannot look at the other party's technological equipment based on the technological level of the earth."

Peshkov frowned: "I don't think so! When the other party contacted the earth for the second time, he could obviously perform time and space operations.

"What if the other party has obtained the theory of great unity and opened the door to other dimensions? Then we can only start with their equipment when we look for the other party's entry point."

Lorfo, who had lost weight, did not agree with Peshkov's point of view: "We have been looking for it for so long, and it turns out that we cannot observe their equipment!"

Peshkov leaned tiredly on the back of the chair: "Maybe we have overlooked something, but their communication facilities are finally a breakthrough.

"If, as you said, the other person's life form is something we cannot observe, how should we search?"

Theodore and Lorfo were silent. They looked at You Haoming, who was holding his arms and thinking, and Bishkov had a quarrel and took a sip of water and looked at You Haoming.

You Haoming's mental outlook is the best among astronauts, at least his face is clean and without beards.

He noticed the three of them, let go of their arms and said, "Everything is unknown, and any assumption may be valid."

Peshkov and Theodore were still staring at You Haoming, and You Haoming smiled: "There is no answer on my face, but I suddenly thought of what does the sentence "I don't exist" mean in the message to the other party to the earth?"

At this time, Mi Jingtao, who turned his back to the camera, said: "The command is long, that may be the ambiguity caused by the different understandings of the concept of 'existence' between two civilizations."

After a few seconds of quiet in the conference room, You Haoming said: "No, this is a reminder. Maybe for us, the other party really doesn't exist!"

Everyone was stunned at first, and Peshkov said first: "If they don't exist, what else can we come to look for? They must exist."

You Haoming explained: "I don't mean that. All the search methods we use now are based on our existing technology and thinking level.

"If the other party is giving Earth civilization a test, do you hope that Earth civilization can have some enlightenment during the test?

"Should we think in a different direction? If the earth's civilization is more advanced than it is now, how would we think about the problem of 'existence'? What methods would we use to find unknown things?"

The other four astronauts were silent.

You Haoming sighed: "We have too little rational thinking about the future!"

Then he said to Theodore: "Send my thoughts to Xichang and brainstorm to see if they have any better suggestions."

...

You Haoming's guess made PDC fall into Jiang Yu's trap again, so that the last step of the "Zero Plan" can be taken more calmly.

After returning to Beijing, Yang Dong quickly hibernated.

Jiang Yu had almost no negative feelings about this because he knew he would meet again in the future.

Immediately, Jiang Yu quickly returned to his work state and focused all his energy on the end of the "Plan Zero".

On the day that the wisdom signal from Mars has been received for a year, everyone in the world will look up at the sky intentionally or unintentionally.

They don’t know where Mars is, but they really hope to know what the consequences will be if they fail to complete the other party’s test?

Many people are already a little disappointed. There is no need to expect the help of advanced civilizations. Just don’t take the opportunity to make things difficult for humans.

Large radio telescopes on the ground and some satellites in low-Earth orbit are all paying attention to the direction of Mars.

You Haoming and five Mars astronauts also sent out smart signals before, hoping that miracles would happen and that they could find each other at the last moment.

On Earth, at 10 a.m. Beijing time, radio telescopes on the ground and satellites in low-Earth orbit once again received smart signals from Mars.
