The territory of Amoeba's rule is not linear expansion, but more like the ripples of water falling on the water. In addition to the seed rescue mission to the Serines, stars in other directions are also being expanded and colonized by collectors.

　　 The other direction perpendicular to the initial direction of their expansion, the collectors who completed the colonization of the new fringe territory of this ethnic group not long after, suddenly received an unfamiliar signal from other places indirectly.

　　 "Received radio signals from outside the star system."

　　 "Any clan is coming?"

　　 This was the first reaction of other collectors after hearing the news, but soon, the collectors who thought this way were refuted by their other kinsmen.

　　 "We are the colonizing star on the frontier of the race, and there is no race in that direction."

　　 "Huh? Then who sent this signal source?"

　　 The news came too suddenly, and some collectors hadn't reacted yet.

　　 However, their brains are still not on strike, and their brains begin to analyze the information they have obtained logically.

　　...An unknown signal is received from outside the star system... The direction is not from the ethnic group... It is very likely an alien civilization...

Under the derivation of the logic chain, the collectors began to get excited.

　　 "...It's a precious ethnic resource! What are you still doing? Hurry up! Hurry up and call out the star map! We have to determine the coordinates of their signals."

　　 Collectors directly define it as a resource. In fact, it’s not wrong to understand it this way. For collectors, alien civilization is a treasured resource that can provide technical promotion to the race.

　　 "How do we determine the coordinates?" a collector asked.

　　 This unfamiliar radio signal is not complicated, so it does not carry much complicated information, it is just a simple signal.

　　 This signal is most likely just a radio signal for other purposes, not for communication.

　　 Therefore, collectors are not sure whether such signals will be repeated again. If the signal source only intends to send radio information once, how should they obtain the coordinates of the signal source?

　　The leader of the cluster half reprimanded and half explained his plan in the channel.

"I ask you to be more mindful in normal times. Look, now when you want to use it, you don’t know how to use it? As long as there are two platforms at different locations receiving the signal, a straight line is infinitely extended from the direction in which they observe the signal. Then calculate the intersection of the two straight lines, and you can naturally learn where the signal source comes from."

Although every collector has the same knowledge memory, the memory is ultimately memory, not the level of understanding of knowledge, like forcibly memorizing a book. However, due to the memory of the person’s own factors, the content of the book is not in the mind. Unavailable.

　　 After the explanation of the leader of the cluster, other collectors woke up one after another.

　　 "It turns out that's the case."

　　According to the method of the group leader, the collectors began to calculate to calculate the coordinate position of the star where the signal source was located.

　　 It didn't take long for them to find it.

　　 "I found it! Uh...but this location is a bit strange. There is no star at this coordinate."

The collector reported by 　　 was hesitant, because there was no star at the location of this signal source, and even with the coordinates as the center, there was no star in the range of two light-years and three light-years in radius.

　　Such results make the report collectors very puzzling.

　　 "Did you make a mistake?" the leader of the cluster asked.

　　 "No, I checked twice before reporting, and there is indeed no wrong calculation."

　　 The leader of the cluster thought for a while and asked again.

　　 "Did you substitute the stellar displacement? The stars are constantly moving in a circle around the center of the river system."

"Considered."

　　 "Then do you consider the delay factor of the speed of light? When the signal is transmitted to us, there will be a significant delay on a large scale."

　　 "Also considered." The report collector replied.

　　 "Why is that not? Is the observation direction deviated?"

　　 This time, the leader of the cluster was also puzzled. It thought of the last possible mistake, but the answer from the same clan made it feel a little uncomfortable.

　　 "I don't know, it doesn't feel like the reason for the deviation. The signal source is only five light-years away from us. Even if there is a deviation, it is impossible to deviate as much as two or three light-years."

　　 After other collectors heard the information, some individuals made guesses.

　　 "You said...Will this alien civilization be like us?"

　　 "What's the same? Another ethnic group?"

　　 The individual explained, "No, I mean the way of expansion. The radio signal we received is a deceleration signal that the alien fleet uses stellar reflection to descend from sublight speed. Didn't we do that?"

　　 "You mean, a fleet of alien civilizations is approaching us?" the group leader asked.

　　 It also thought of this, but later than the individual expressed it.

　　 "That's what it means." The individual replied in the affirmative.

　　Everything must be considered for the good and the worst. After combining the current intelligence, the collectors agreed that this is an alien civilization with similar technology to them.

Civilized contact is also wild contact, often accompanied by wars and killings. This is what the collectors have learned from the history of the Celine people, so they dare not slack off, even if they believe that the other party will be in the star system. The colonial cluster launches an offensive, and the collectors need to prepare for the coming war.

　　 The preparatory work for the war is proceeding like a raging fire. Since they learned that the alien fleet is going to the colony star system of the collectors, they have carried out such resource mobilization again.

　　They don't know whether the alien fleet is an enemy or a friend, so they can only prepare for the worst, believing that the alien fleet intends to invade their colonial star system.

　　 "Quick! Get ready for battle!"

　　The leader of the cluster urged in the channel, and other people of the same clan will also explain to the leader of the cluster clearly the problems that have arisen one after another.

　　 "Antimatter! Antimatter resources are not enough!"

"The output of antimatter has been increased, and other industrial giants have halted, and they are producing antimatter giants with all their strength!" According to the problem cluster leader, they gave an order to the same clan, and then thought of another possibility in the later stage of the war, and communicated to the stars. Of the same clan promulgated tasks.

　　 "Seek help from other colonial stars! Tell them that our war resources are not enough! It is very likely to be defeated, so you must be vigilant!"

　　 "Understood!" the family in charge of stellar communications replied.

　　 Then, the leader of the cluster began to pay attention to other aspects of affairs.

　　 "How is the combat plan made?" the group leader asked.

　　 The collectors who are making a battle plan answered.

　　 "We have already thought about it, adopting the method of sticking to the star system, our resources are more abundant than the other party, and we have the time and space to deploy, we can transform the colonial stars into a battlefield."

　　 "What if their technology is above us?" the cluster leader asked.

　　 "In the worst case, we are crushed by their technology. If that is the case, we will create a supernova explosion~lightnovelpub.net~ and drag them to die with us."

The collectors also considered the technological gap, not to mention the current star system, because it hasn’t been too long since colonization, the planet has not been demolished, the number of antimatter megastructures is not enough, and the antimatter reserve is not large, so Yuejin Bio is armed with antimatter. Resources are also insufficient.

　　 Therefore, the collectors feel that they are at a great disadvantage.

　　 "Of course, it is not known whether this method of homicide is effective or not." The collector who made the battle plan added.

　　 The leader of the cluster replied, "Regardless of whether it is useful or not, just use whatever feels useful. This alien civilization can sail across stars just like us. You must be as cautious and overestimated as possible, understand?"

"understood."

　　 After being affirmed by the leader of the cluster, the collectors who made the battle plan began to explain the battle plan in depth.

　　 "Then we should be like this, arrange the focusing array on the stellar orbit, and then spread the signal sub-body in the star system to lock the enemy fleet with higher precision, and also make a large number of mother ship creatures..."

　　 "Wait, is the mothership creature still useful?" the group leader asked.

　　 "A large number of Mothership creatures can provide cover for Leap Forward creatures. The opponent will miscalculate our strength and kill them by surprise."

　　 "This is not their home field, so it is difficult to obtain war supplies. In addition to relying on the superiority of technology and the huge combat force, if it is the same technology, our side should have an even greater advantage."
