After the exchanges, new human scientists at various points in time also came up with many plans.

However, there are very few valuable schemes, and the occasional schemes with shining points have also been proved ineffective in subsequent experiments.

The progress of the Time Loop project has come to a standstill, and the answer seems to be close at hand, but in fact it is far away.

It is still within the 3088 Research Institute of the Parallel Time and Space Research Institute, and 247 Blue Star years have passed since the proposal of the Time Ring project.

Over the years, Zhang Wang and others have organized academic exchange conferences every once in a while.

Today is the 18th academic exchange conference organized by the institute.

At the exchange meeting, Duan Zangfeng, Gong Qingjie and other parallel space-time research institutes, as well as Wei Feng, Zhang Ziqin and others.

The crowd had a heated discussion on recent scientific research results, theoretical knowledge, and new ideas, and the scientific research progress under this model is obviously much better than the previous closed-door work.

In addition to the new human scientists at each time node, we also have regular academic exchanges to ensure that science and technology can be fully shared.

Wei Feng and Duan Zangfeng are also old acquaintances, and the two of them are discussing in a whisper in the corner.

"Old Wei, I heard that you have updated a superstate particle?"

Wei Feng smiled calmly: "Yes, it was just completed half a month ago, and it is a very potential new material." ”

"Envy!" Duan Zangfeng shook his head and sighed lightly, the progress of various projects of the Parallel Time and Space Research Institute in recent years has been quite slow.

Although it is much better than when there was no rectification before, scientific research sometimes requires a little luck, and blindly forcing it may not necessarily lead to corresponding gains.

The delay in making progress made Duan Zangfeng sad.

Wei Feng comforted a few words: "Zangfeng, some things are in a hurry, just let it be." ”

Just as Duan Zangfeng was about to say something, there was a loud argument in the crowd not far away, as if they were discussing some new ideas.

The two of them, who were originally a little unimpressed, fell into deep thought after listening to a few words with their ears attentively.

Wei Feng, whose eyes were slightly thoughtful, looked at Duan Zangfeng, who was also speechless: "Zangfeng, what do you think?"

Duan Zangfeng replied without hesitation: "If we can guarantee that the Destruction Node cannot destroy the marker, it is indeed possible to preserve the Ring of Time for a long time. ”

"The key to this plan is how to ensure that the marker is not destroyed by the destruction node." After Wei Feng finished speaking, he fell into thinking again.

The marker scheme proposed by the scientist is sure to be successful, but there is no eternal marker in even three-dimensional space-time, let alone the strange four-dimensional space-time.

In fact, to complete the Time Loop project, there is a more simple and crude solution, which is to cut the causal relationship between time nodes.

It's just that this kind of scheme is obviously not something that can be snooped at at this stage, and the law of cause and effect is, to some extent, more unfathomable than the law of time.

According to the relevant research and analysis of the Science and Technology Commission, in the four-dimensional space-time, those ordinary four-dimensional creatures should not involve advanced causal laws.

In fact, the way of killing the future timeline by attacking the past time node is a superficial application of the law of cause and effect.

Wei Feng, Duan Zangfeng and others who were contemplating were not too far away, and they were still studying other plans in a down-to-earth manner, and the law of cause and effect was not something that should be deepened now.

The scientists at the exchange meeting were also thinking hard at this time, and how to ensure that the markers were not destroyed by the destruction node involved a lot of problems.

In order for the marker not to be destroyed by the destruction node, the first prerequisite is that the marker can withstand the attack of the four-dimensional creature.

Normally, the attack methods of four-dimensional creatures include common ascending weapons (i.e., pouring high-dimensional information), rule reduction (restoring the material carrier to a disordered state), time cage (an alternative application of the time ring), etc.

These are still speculated by the new humans themselves, as for whether there are other means, before advancing to the four-dimensional space-time, the difficulty of understanding most of the four-dimensional creatures is like the landing of modern humans on the moon.

Wei Feng shook his head: "The premise of this plan is that we have enough understanding of the attack on the fourth dimension, but it's a pity." ”

"Give it a try! At least it can be used. Duan Zangfeng was also helpless, and now they could only be dead horses as live horse doctors.

In the 3088 Research Institute, while everyone was discussing fiercely, Zhang Wang and the others, as the host, were not idle.

In the lab where the Ring of Time is being studied, they begin to create markers inside the superrobots in an attempt to evade the arrival of the Node of Destruction.

The attack of the destruction node actually depends on the type of attack when it is launched, like the common ascending weapon, which is basically immune to it.

But other means of attack, simply destroying the past node, is a dead knot that cannot be solved.

Everything exists in the past, unless the new humans can find the starting point of the past, that is, the starting point of the four-dimensional space-time timeline.

The problem is the starting point of the timeline, and this thing may not exist, which is embarrassing.

The past without a starting point means that it is extended indefinitely, and as long as the enemy has enough patience and traces the source along the timeline little by little, a weak time node can always be found, so as to achieve a one-hit kill.

In fact, the beacon body of the Ganwa space-time empire was a kind of marker before, but the scientific and technological content was only at the quasi-four-dimensional level, and when facing the four-dimensional eye, the Ganwa space-time empire directly hit the street.

If you want to keep the markers in three-dimensional space-time, the difficulty is absolutely hellish, because from the perspective of four dimensions, everything in three dimensions is almost transparent.

"Old Wei, can you adopt dimensional rules and then adopt the macroscopic universe."

Wei Feng was stunned, he was quite familiar with this plan, and the trader civilization had adopted a similar plan back then, setting the future return on the red dwarf.

It's just that as soon as he thought about it deeply, he understood that this plan also had no possibility of success, and it was still that problem, the four-dimensional can easily observe the three-dimensional, and it was basically impossible to hide this kind of small action.

Although this plan is not very feasible, Zhang Wang still did relevant experiments, and the results are self-evident.

Even new humans who have not yet been promoted to the fourth dimension can easily observe anomalies through the extradimensional detection system, let alone those four-dimensional creatures.

The path of markers is destined to be an expedient measure, perhaps some ordinary four-dimensional creatures may ignore the past, but if they are used more times, sooner or later they will be exposed.

I was so nervous that I couldn't figure out a solution.

Just when everyone was at a loss, at the door of the meeting site, a figure was suddenly projected, and I saw that the person had a happy face and floated in the direction of Duan Zangfeng.

"Academician Duan, good news."

Duan Zangfeng, who was interrupted from thinking, only then did he find out that it was his assistant Li An: "Xiao Li, what's the good news?"

Li Ang didn't sell it, and immediately explained his intentions: "It's this shared technology, which was just sent from another time node." ”

After getting the shared scientific and technological information, Duan Zangfeng browsed it carefully with curiosity, and Wei Feng on the side also took a copy of the shared information.

The more he looked at it, the smile on Duan Zangfeng's face became more and more intense, and even his hands were trembling slightly, obviously the good news in this information made him a little uncomfortable.
