According to the plan, the Olive Branch civilization should still need some time before launching an attack. However, Yan Xia did not expect that this period would come so quickly.
Approximately 210 years after the destruction of the Kunpeng, the Cangku Star Domain suffered the same treatment as the Silk civilization—supergravity weapons.
This is the only known super-distance weapon of the Olive Branch civilization to the Federation, but its underlying principles remain a mystery, and they have only been speculating about it.
This time, the Olive Branch civilization gave the Federation a rude awakening.
It is evident that the Olive Branch civilization is well aware that the Federation tends to cluster around massive stars, so this time they targeted Sirius for their assault.
As the core star system of the Cangku Star Domain, Sirius itself was equipped with many defensive measures, including a negative energy barrier that the Federation had high hopes for.
However, the Olive Branch civilization's supergravity weapon did not even trigger this barrier and directly destroyed Sirius.
After thousands of years, the Cangku Star Domain once again faced a great panic.
...
In a vast hall, all scholars were silent.
"Gentlemen, what do you think?"
The discussion about the Olive Branch War was held very close to Sirius; they did not even need to wait for information from their star but could directly observe Sirius collapsing and exploding into a planetary nebula with their naked eyes.
This was not the first conference on the Olive Branch War; it was already the seventh session.
As long as the threat from the Olive Branch civilization does not disappear, this conference will continue to be held, not only here but also similar meetings are taking place in other star domains.
"The negative energy used in this context should be able to isolate all positive energy; however, since the Olive Branch civilization's supergravity weapon still struck Sirius, it indicates that this weapon did not use any positive energy at all."
The scholars furrowed their brows; this exceeded their understanding. What could bypass negative energy?
"There is a paper uploaded directly by a mechanical deity on the Federation's P7-level thesis website 'Planck,' which mentioned that the Olive Branch civilization can explore at a micro-scale deeper than we can."
"Negative energy is gravity; it can be described in three dimensions and perceived in one dimension but we do not know what properties it has in two dimensions. Can it penetrate through negative energy layers? Does gravity in two-dimensional space have superluminal propagation characteristics?"
This was an uncertain matter. Some scholars began calculating on their panels when a physicist stood up: "No! Negative energy itself can exist in two-dimensional space."
"The reason we believe it does not exist is that we have not observed its state in two-dimensional spacetime."
"Negative energy itself is related to gravitational field capabilities. Let us assume that negative energy in two-dimensional space cannot obstruct the Olive Branch civilization's supergravity weapon; however, it also cannot respond to gravity. I am more inclined towards another explanation regarding our speculation about supergravity weapons."
"The supergravity weapon of the Olive Branch civilization connects two ends of spacetime through wormholes. The gravity from point A is transmitted to point B through impulse, and vice versa; sudden changes in gravity cause both A and B to collapse suddenly. However, since the Olive Branch civilization controlled gravity changes at point A with their star city, point B would collapse."
"If this is true, then it explains why there were no changes detected because gravity bypassed through wormholes."
This hypothesis was quickly rebutted by another scholar who stood up.
"There is a crucial question here: how does the Olive Branch civilization locate coordinates?"
"They cannot aim their weapon at point B; if point B exists as a black hole!"
"What they must do is create a black hole at point B."
"If they used a super-distance device for positioning, it would inevitably trigger negative energy, so your theory is incorrect."
"I don't know if everyone has noticed; Sirius's mechanical deity's last log report has come out and has been forwarded to me. I don't know if you all have received it."
"I noticed something very important: previously infected individuals from the Silk Road had existed on Sirius. Could it be that the Olive Branch civilization used similar means?"
"Emerald light!"
Speaking of emerald light brings us back to two-dimensional levels; this seems to be an unavoidable topic.
Everyone fell silent once again.
About seven months later, a voice finally broke this silence.
"In fact, we may have complicated things..."
"I reviewed many deep-level materials which mentioned that these infected individuals subsequently became explorers and possessed their own spaceships."
"Is this a coincidence?"
"Previously everyone thought that there were too many explorers in the Federation and these guys had records as infected individuals which might lead many large companies not to hire them; thus they could become explorers."
"But I feel there is some connection here; of course, there is currently no conclusive evidence for this connection."
"When I discovered this point, I had already borrowed here's quantum communication device to send a request to an assistant in nearby star systems; now that request has been returned to me."
He directly displayed the information he received; it subsequently landed before every scholar present.
"Dear Palmerfoss,
In accordance with your request, I have traveled around Andromeda HH for some time. Through your identity, I obtained some exploration privileges and confirmed over 170,000 bodies through mechanical deities."
"As you expected, among those 170,000 bodies are many unregistered ones. I had mechanical deities check them one by one."
"Some bodies were detached from mechanical deities due to faults or age while others are so-called black bodies created by some interstellar pirates. To be honest, this is very troublesome; I am flying through space analyzing every moment."
"But hard work pays off; finally on one surface spot of Andromeda HH I discovered an unusual body. It itself is not large but has an extremely high mass; based on estimates I believe its density might exceed 70g/cm³ which is extremely unusual. When I approached it, it directly hid into the stellar corona and reappeared when I distanced myself. It exhibited certain intelligence and according to my probing device—it does not exist but can only be observed with my naked eyes."
"I apologize Palmerfoss for acting without following your command; I fired a laser cannon at that device. The power of this laser cannon was low but after being hit, that device actually disintegrated into atoms."
"I hope what I found can assist your research—your assistant Jack."
This is a standard letter format.
It does not conform strictly to the Federation's letter format but such formats are quite common within virtual games set in Western fantasy backgrounds and are liked by some people.
After reading this letter, everyone reached a consensus.
If this is true then they had indeed overestimated the Olive Branch civilization previously.
