All in all, the current level of communication between human beings and Toth civilization is still limited to conventional means such as electromagnetic waves and neutrinos, and gravitational waves that have not yet been studied can also be regarded as one.

Gravitational waves can withstand very little information and need to be triggered by excitation of cosmic strings. It still travels at the speed of light, and there is no way to exceed the speed of light.

Quantum entanglement can be faster than the speed of light, but quantum entanglement cannot transmit any information, which is theoretically stipulated, and there is no way to break through.

Just like the law of conservation of energy, mankind has never discovered a physical phenomenon that can violate the conservation of energy, nor has it ever discovered that quantum entanglement can transmit information.

Listening to the analysis of this Toth civilization professor, Zhang Yuan nodded below, for a faster-than-light spaceship, the received external signals are already very chaotic, and it will become extremely complicated for the two spaceships to communicate.

"This is bad news. Li Zhendong, what do you think, in the future, we will have six motherships. If you can't communicate with each other, no one will know if you lose one! ”

As an information expert, Li Zhendong shook his head, he still has a lot of say in this regard, "No way, this is the case after breaking through the speed of light." ”

"Two parallel faster-than-light spaceships that can't see each other and can't communicate with each other."

“…… Two ships in front of the other in the back, the ship in the back can see the front one, but the one in front cannot see the one behind. ”

"Theoretically, it is impossible to break through this, unless we develop a means of faster-than-light communication. Say fast, or whatever......"

Why? Because the ship runs faster than light!

Curvature navigation, since it is the movement of space itself, does not involve relativistic benefits.

The two parallel ships, one emitting signals to the other, electromagnetic waves with a speed of only the speed of light, immediately fell behind. It's like throwing a softball out of a speeding car, but the speed of the softball can't match that of the car, and it is thrown off with a "brush".

"So we only think about the communication situation in front of the back, and the spacecraft in front can transmit signals to the rear, which is no problem......

"However, there may be a certain amount of delay in deciphering the information in real time."

“…… I think we can design a fuzzy signal. You don't need that kind of particularly accurate signal, as long as you can communicate with each other, it's like ......" Li Zhendong pondered to himself, although he was not very serious when he spoke, but once he worked, he was still quite serious.

"Could it be that our ship is going to fly in front and back, it's too unsafe and it could crash into ...... Can it also be herringbone, flying diagonally? ”

At this time, the great scientist on the stage had finished speaking, and there was a warm applause from the audience.

The Tothian also knew that this was the way of human etiquette, and he seemed to enjoy it very much......

In fact, he could only perceive through ultrasound, and could barely feel the humans shaking.

This venue is empty, ultrasound perception is not enough, it is very vague, and the frequency of human applause is not in the same channel for him at all, and he can't hear it at all, which is another big tragedy......

Soon after the meeting, several more Tos, led by human diplomats, found Zhang Yuan.

"Mr. Zhang, our ...... When does the co-op program start? A Tothian, who looked like a leader, said straight to the point.

"Can you sell the kind of brain-in-a-jar technology you are talking about? Nor is it for sale...... In short, 1,500 amoeba points is the biggest price we can bear, and we really can't take more. We know that this technology, in the trading market, may cost 10,000 amoeba points......"

"We can also trade some more core technologies, and at that time it was already said that the core technology of 4500 points, this is the most we can come up with...... You can't go back on it! ”

For the Toths, they can't see the faces of other people, and the usual way to distinguish their friends is by smell, but now they are all wearing spacesuits, and they can't distinguish the smell of humans.

And after such a long time, the leadership of the Tothians has long since changed, so they don't know that the one in front of them is actually the one back then.

Zhang Yuan saw the urgency of these large baby fish, and said with a smile: "Don't be in a hurry, Your Excellency Gakro, this is a big project, it can't be completed in a day or two!" If you say yes, we won't pay off! ”

"Our researchers have been waiting for a long time. We can't make promises, but we'll do our best! ”

The Tothians quickly received a copy of the research material and read it on their own special readers.

When they discovered that humans had developed two new "colors" in their field of vision, they were amazed to communicate with each other.

Although they don't know what "color" means, they have never heard of such technology in all their years of being in the trading market.

This is definitely the closest they can get to magnetic field sensing!

"Your civilization really has a talent for this, and as far as we know, many fourth-level civilizations can't do this. This aspect of the technology tree can be regarded as the unique technology of your civilization. ”

Speaking of talent and the like, Zhang Yuan was a little embarrassed and didn't answer. This technology tree was born out of an adventure, and it is not a unique talent. However, it is also the efforts of human beings themselves to be able to seize the opportunity.

"Lord Gacro, please ...... here."

Diplomats on both sides soon began to negotiate relevant trade, sign various safeguard treaties, and so on, which is a win-win event for both sides.

The Tothians, who were slaughtered again, almost handed over all their wealth, and they were going to die happily. In their expectations, it seemed that they were about to witness the so-called light.

"Whew!"

"Whew!"

The big wolfdogs, too, knew that this was important to their companions, and wagged their tails wildly. All they can do now is wag their tails and curry favor with humans......

Zhang Yuan was overjoyed when he saw those diplomats, and hurriedly pulled him aside and instructed: "Don't kill too hard, the friendship between the two sides must be maintained, you can't catch a fat sheep and wipe all the wool!" ”

"No, no, no! Mr. Zhang, you're wrong......"

"The best way to maintain friendship is not a gift, but an equal exchange between the two parties!"

"If this plan succeeds, it will be equivalent to us eating the vast majority of the tech tree of the Thor civilization. Although the technology tree of this civilization is broken, it is still very powerful in the powerful places, and it is definitely worth the money! In this way, in the third-level civilization stage, the lack of heritage caused by staying too short will be fully compensated! ”

The diplomat walked out of the door of the room, literally trembling with excitement.

"You may have underestimated the desire of the Toth civilization to have optical perception," he said...... If you can actually give them optical perception! When the time comes, everything will not be a price for them, but will be turned into gratitude......"

"Anyway, as long as the work can be done, everything is fine!"

"That's fine." Zhang Yuan didn't dare to pack the ticket, but just made a gesture.

For this matter, their entire laboratory has been preparing for a long, long time, and the certainty of success is quite high.

"Can you give me a cover? What is the success rate? Depending on the probability of success, our negotiation techniques will be a little different. ”

Zhang Yuan thought for a while: "We already have some biological data of the Toth civilization, and we have also studied it for some time, plus the talent team that has been cultivated so far, the highest ...... Seventy percent sure! The success rate can't be increased again. ”
