This civilization is very strong, but the technology tree is a bit crooked

"come yet?"

Chen Yi's expression was startled, and then he nodded: "Let's go and take a look."

Today, after several technical update iterations.

Yifei's tachyon space-time detector has a detection distance of more than 10 light years.

Especially when we know the location of the universe's dimension-enhancing force base, we have specialized in directional detection, a longer detection range, and a more accurate space-time detection array.

When turned on at full power, space-time fluctuations over a distance of 30 light years can be obtained through tachyons.

With this detection array, Yi Fei is finally not blind when it comes to the dimensions-enhancing forces in the universe.

You can get information about the coming attack earlier and be fully prepared for the response.

"Mr. Chen, the speed of the cosmic dimension-raising forces this time is even faster than the 350 times the speed of light in the first time, reaching 480 times the speed of light, and there are more of them. Conservative calculation, no less than 10 units."

As soon as Chen Yi arrived at Yifei's external relations department, Lin Qian and He Yu, who had also received the news and arrived in advance, greeted him.

Among them, Lin Qian even took out a report and submitted it to Chen Yi.

"480 times the speed of light."

"It seems that the other party is in a hurry this time."

"How many light years away from the solar system?"

Chen Yi took the report and asked casually.

"31.3 light years."

"So, the other party can reach the solar system in less than a month?"

Chen Yi carefully looked at the data in the report and turned to He Yu and asked: "Research center, how is the research on curvature super-light navigation technology progressing?"

Yi Fei obtained samples of three key technologies from the smart battleship that was first attacked by the space-ascending forces, namely quantum materials, quark energy engines, and curvature navigation engines.

Among them, quantum materials and quark energy engines were developed by Chen Yi alone.

The Yifei Research Center has only one mission left during this period, which is to conquer the curvature super-light navigation technology.

In interstellar warfare, navigation technology is a very critical link, even a decisive link.

To paraphrase the classic picture of fighting spirit turning into a horse, your horse is not as fast as mine, and Dou Di is helpless.

In the same way, the same goes for interstellar navigation technology.

It determines whether mankind will be beaten in the next war with the dimension-enhancing forces of the universe, or whether it will be able to fight back.

As long as there is no breakthrough in curvature super-light navigation technology, humans and Yi Fei will be in a passive state. They can only defend passively and cannot take the initiative to attack.

"Mr. Chen, we are still in the exploration stage. It is conservatively estimated that we will not be able to complete the technical breakthrough before the second attack of the cosmic dimension-enhancing forces."

He Yu was on the side and answered with a somewhat solemn expression.

After such a long period of training, she also understood in her heart what the curvature super-light navigation technology meant to Yi Fei.

Now, the second blow from the cosmic dimension-enhancing forces is about to come, but Yi Fei's super-light speed navigation technology has not made a breakthrough, which undoubtedly puts Yi Fei into a passive state again.

"Since there is no breakthrough, forget it."

Chen Yi shook his head and did not blame anything.

At that time, because he was not sure whether the warships of the cosmic dimension-enhancing forces had mastered memes, and in order to ensure foolproof safety, when the intelligent warships of the cosmic dimension-enhancing forces came over for the first time and were damaged in the attack, Chen Yi continued to order the attack, almost completely destroying the warships. That's all.

Except for the quark energy center at the center of the battleship, it remained roughly intact, allowing Chen Yi to repair it and develop quantum transformation materials and quark energy engine technology.

As for the instruments related to curvature navigation equipped on the warship, they have long since turned into ashes and a pile of fragments, with no rough shape to be found.

In this case, if you want to study and overcome curvature navigation technology, it is no less difficult than starting from scratch.

Even if the personnel of Yifei Research Center have already carried out quantum neuron transformation, the virtual acceleration multiple can be fully increased, and with the experimental verification of Yifei's strong productivity, this will not be conquered in just a few months.

After all, this is not junk technology.

The curvature navigation technology is a true space-time technology.

"Our technology for quantum transformation of materials has been perfected, and various instruments and equipment can be made more miniaturized."

"The breakthrough of the quark energy engine allows us to completely get rid of the shackles of material energy."

Chen Yi thought for a moment and then ordered: "In the next time, Yi Fei will try his best to build unmanned warships, move the mass cannons that can eliminate the vacuum and borrow energy to the platform of the warship, and then spread the warships around the solar system."

"Since we can't win with quality, we will crush them with quantity."

"As long as the opponent does not transcend the current level of time and space, our mass cannon will definitely surprise the opponent."

With the Higgs field mass elimination technology mastered, the speed of the battleship can approach the speed of light.

Based on Yi Fei's current productivity, in less than a month, this would be enough to turn the entire solar system into an iron bucket, a watertight iron bucket with a defense zone covering a radius of more than ten light-days.

No matter what kind of battleship the cosmic dimension-enhancing forces dispatched this time.

As long as there are enough battleships to form a blockade and coverage attack, and as long as the mass bomb attack is still effective, the opponent will have only one fate, and that is death.

"in addition."

After Chen Yi finished speaking, he seemed to have thought of something, and added: "In addition to the battleships used for combat, the monitoring network of the solar system also needs to be strictly arranged to guard against the intelligent battleships of the cosmic dimension-enhancing forces that directly attack the major planets in the solar system, including the sun itself. Attack."

"There is also the first attack by the cosmic dimension-enhancing forces, and the fire plan prepared by Yi Fei, which is also launched simultaneously."

"Ensure that the billions of fire warships of human civilization will be released as soon as an accident occurs and the defense line fails."

"receive!"

"clear!"

He Yu and Lin Qian responded to Chen Yi's instructions without any hesitation, and then began to mobilize resources to prepare.

time flies.

Twenty days have passed since Yi Fei discovered the news of the second attack by the dimension-enhancing forces of the universe.

With the automated production system that has been updated and iterated many times, there are also countless engineers who have entered a virtual acceleration state to remotely control production.

Yifei spent twenty days using modular production to build more than 30 billion warships equipped with core technologies such as quark energy engines, Higgs field mass eliminators, vacuum energy borrowing mass cannons, and gamma ray propulsion engines. Distributed within 20 light-days around the solar system, it forms a huge defense zone.

In order to meet this production task, Jupiter successfully completed the slimming operation, and less than 10 of the 79 satellites were excavated.

Planet-based resources and immeasurable materials are transformed into battleships and technological weapons in Yifei's production base, and are invested in the armed defense of the solar system.

The curvature navigation signal, which represents the second strike of the dimension-raising forces of the universe, has officially spanned a distance of dozens of light-years and arrived beyond Proxima Centauri, less than 4 light-years away from the solar system.
