The investigation was carried out by Lu Yaohua, and Jiang Haitang and Jiang Haitang were both near the Wall of Sighs.

A man is in charge of screening Gong Zhi, a space-time wave that investigates the Wall of Sighs.

Dense probes and reconnaissance spaceships, under the control of ghost agents at various intelligence points, touch the past one by one timeline and one time node.

According to the relevant research of the Science and Technology Commission and the Ghost Secret Service, the Thought Radio of the Banner of Freedom, because it does not understand the internal situation of the Wall of Sighs, emits space-time waves, which must be multi-band and multi-power.

After passing through the high-velocity time zone of the Wall of Sighs, it is actually unknown how many space-time waves can successfully reach this side.

The passive siren placed on the outer layer of the Wall of Sighs is also constantly collecting space-time wave data, and Jiang Haitang was ordered to set up a "Outside the Wall Information Investigation Team" to specifically analyze the space-time waves transmitted from inside the Wall of Sighs.

The investigation was extremely difficult, and the high velocity of the Wall of Sighs was enough to kill most of the space-time waves.

It's not that space-time waves can't be transmitted, but that after the destruction of high-velocity time, those space-time waves have changed beyond recognition.

Even if some of the information can be retained, it is incomplete.

It is indeed a difficult problem to identify those space-time waves with ulterior motives in this vast sea of space-time waves.

Jiang Haitang mobilized a large number of super-space-time computers to devote himself to data analysis.

Inside the base of the observatory.

Jiang Haitang, who had just returned, hurriedly inspected the work of the observation station, and Zhang Kaixuan, who was temporarily in charge of the work here, gave him a brief report on some recent situations.

"Team leader, in this 12 areas, signs of other four-dimensional civilizations have been discovered, of which five civilizations are known, and the remaining civilizations are discovered for the first time."

Jiang Haitang looked through the details and asked, "Do they have any other actions?"

"Except for the Eternal Lands and another new civilization, no other civilization has moved."

Jiang Haitang muttered to himself: "The Eternal Ancient Land has launched 150 spaceships; The new civilization has built a base. ”

For these circumstances, it is not until he is not surprised, the new human civilization itself is a latecomer, and he will be surprised by the Wall of Sighs.

And those old four-dimensional civilizations, it is estimated that the vast majority of them have understood the Wall of Sighs, and they must have probed the situation in it.

Over the years, the Ghost Service has found many ruins or wreckage, which are traces of the four-dimensional civilization's exploration of the Wall of Sighs.

After listening to Zhang Kaixuan's report, he opened his mouth and ordered: "Kaixuan, you pay more attention to the work here, I have too many things recently." ”

"No problem." Zhang Kaixuan nodded.

Jiang Haitang, who was in charge of a number of tasks, immediately rushed to the Freedom Spacecraft Research Base, and Li Jianfeng and others had recently analyzed a lot of information in the recent research on those three spacecraft.

Although the destruction of the Wall of Sighs caused unimaginable damage to the three freedom ships, inside and out, the remnants still brought a lot of gains.

For example, some of the materials and some of the technology of the Banner of Freedom, most of which are incomplete, have given new human scientists a lot of inspiration and reference.

The Science and Technology Commission mobilized many scientists to participate in the research of the Freedom Spacecraft, and through reverse engineering, it made up for many shortcomings of the new human beings.

At this stage, the new human civilization, compared to the vine forest empire, is at most lacking some killer technology.

Once one or two killer features are obtained, the new human civilization is a genuine high-level four-dimensional civilization.

And Jiang Haitang hurried over because of Li Jianfeng's new discovery, which needed the assistance of the ghost secret service.

"Researcher Li, long time no see."

"Team Leader Jiang, this is the test plan I made with a few colleagues, you can take a look." Li Jianfeng shared a document.

Jiang Haitang carefully browsed it, this was a special substance that Li Jianfeng and the others discovered from the freedom spaceship, which seemed to be able to trigger the collapse of time and space.

The collapse of time and space is similar to the suicidal counterattack of the Fujilin fleet back then, which can tear apart the timeline and create a large area of nothingness.

"A hundred grams of disintegrin can destroy an area with a radius of tens of billions of standard degrees?" Seeing this power, Jiang Haitang was also a little surprised.

Li Jianfeng explained: "Yes, the power of disintegrin is very amazing, and its destruction mechanism is similar to the nuclear fission chain reaction in the Common Era, once it comes into contact with the ordinary timeline, it will trigger a strong chain reaction. ”

"And how does this thing stop?" Jiang Haitang asked worriedly.

For this question, Li Jianfeng turned on the virtual display screen and called up a virtual model:

"This is the disintegrant destruction simulation we calculated, after the space-time collapse range reaches 24.4 billion standard degrees, due to the three-dimensional rules in four-dimensional space-time, there is a critical point, which will lead to the formation of a layer of void between the collapse area and the normal area."

"That is, after reaching the tipping point, due to the appearance of the void layer, it will cause the disintegrin to be unable to obtain a new timeline, thus stopping the chain reaction."

Li Jianfeng nodded: "That's what it means." ”

After learning this information, Jiang Haitang felt that the matter was tricky: "In the range of tens of billions of standards, the test site must be at least a trillion standards, and other civilizations must also consider the reactions." ”

The testing of this weapon certainly cannot be tested in the vicinity of the new human-controlled zone.

In addition, the reaction of other civilizations is definitely a big trouble, a bad one, and may even cause misunderstandings.

"Researcher Li, I need to discuss with the above, what is the attitude towards the Science and Technology Commission and the War Commission?"

"The War Commission has agreed, and the Science and Technology Commission is assessing the environmental impact, which may take a year or two." Li Jianfeng did not hide it.

Jiang Haitang already has a general understanding of the situation: "Understand, I won't bother." ”

For the disintegrin test applied by Li Jianfeng, each department has its own considerations, and other civilizations must be very concerned about this weapon of mass destruction.

Once the disintegrant is measured, it will inevitably cause onlookers from other civilizations, and all possible situations need to be comprehensive in order to reduce passivity.

In the heated discussion, the preparations were carried out in an orderly manner.

The development of disintegrant weapons, which is a technology that new humanity cannot give up.

The hot topic of debate now is how to test safely and smoothly to ensure that the new human civilization will not be attacked by a crowd.

The task on the ghost's side is to find a suitable testing ground for the disintegrating elemental weapon.

In line with the long distance, there are not too many high-level four-dimensional civilizations around, there are indeed not too many.

After the disintegrant weapon was officially established, the Ghost Service searched for hundreds of years before finding a barely usable site.

At this time, Li Jianfeng and the others had already trial-produced tens of thousands of disintegrant bombs.

The testing of the first prototype was carried by an unmanned spacecraft to a very distant area.

Another 277 years later, after a long journey, the spaceship loaded with the disintegration bomb finally arrived near its destination.

Just because you're near your destination doesn't mean you can start testing right away.

If there are other bases or spaceships of advanced four-dimensional civilizations nearby, and they kill the other party by mistake, wouldn't it be offended to the other party?

Therefore, before the test, it is necessary to send a cosmic broadcast.
