Amoeba's domination is not a linear expansion, but more like a ripple of water droplets falling on the surface of the water, in addition to carrying out the seed rescue mission of the Serenes, there are also gatherers in other directions who are expanding and colonizing.

In the other direction, perpendicular to the direction of their initial expansion, the gatherers, who had not long completed their colonization of the new marginal territory of this race, suddenly received an unfamiliar signal from elsewhere.

"Radio signals received from outside the star system."

"Someone from the same clan is coming?"

This was the first reaction of the other gatherers when they heard the news, but it was not long before the gatherers who thought so were refuted by their own kind.

"We are the colony stars on the frontier of the race, and there are no people of the same race in that direction."

"Huh? So who delivered this signal? ”

The news came so suddenly that some of the gatherers didn't react.

However, their brains did not strike, and their brains began to logically analyze the information they obtained.

…… Received an unknown signal from outside the star system...... The direction does not come from the ethnic group...... It is very likely to be an alien civilization......

Under the derivation of the logical chain, the gatherers began to get excited.

“…… It's a valuable resource for the community! What are you still doing? Hurry up! Hurry up and bring up the star map! We want to determine the coordinates of their delivery signal. ”

The gatherers directly define it as a resource, in fact, it is not wrong to understand it this way, for the gatherers, the alien civilization is a cherished ** resource, which can provide technical promotion for the race.

"How are we going to determine the coordinates?" A collector asked.

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

It is highly likely that this signal is simply a radio signal used for other purposes and not for communication.

So collectors aren't sure if the signal will be repeated, and how will they get the coordinates of the source if it's only going to send a radio message once?

The leader of the cluster half reprimands and half explains his plan in the channel.

"Tell you to use your brains more often, you see, I don't know how to use it when I want to use it now, right? As long as two platforms in different positions receive a signal, a straight line extends infinitely from the direction in which they observe the signal, and then calculates the intersection of these two straight lines, and it is natural to know where the signal source is coming from. ”

Although each collector has the same knowledge memory, memory is memory after all, not the level of understanding of knowledge, like forcibly writing down a book, but due to the memory person's own factors, the content of the book cannot be used in the mind.

After the explanation of the cluster leader, the other gatherers came to their senses.

"I see."

Following the method of the cluster leader, the collectors began to calculate the position of the star coordinates where the signal source was located.

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

"Found it! Belch...... However, this position is a bit strange, there are no stars in this coordinate. ”

The collector of the report was hesitant, because there were no stars at the location of this signal source, and there were even no stars in the range of coordinates as the center, with a radius of two light years and three light years.

Such results are very puzzling to the collectors of the report.

"Did you miscalculate?" The cluster leader asked.

"No, I checked it twice before the report, and I really didn't make a mistake."

The cluster leader thought for a moment and asked again.

"Did you put the stellar displacement into it? Stars move in a constant circle around the center of the river system. ”

"Considered."

"Do you take into account the delay factor of the speed of light? The signal is transmitted to our side, and there will be a significant delay on a large scale. ”

"I thought about it too." The debriefing gatherer answers.

"How could it not be? Is there a deviation in the direction of observation? ”

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

"I don't know, the feeling is not the cause of the deviation, the signal source is only five light-years away from us, and even if there is a deviation, it is impossible to deviate two or three light-years away."

After other collectors heard the information, some individuals began to make a hypothesis.

"You say...... Could this alien civilization be the same as us? ”

"The same what? Another ethnic group? ”

The entity explained, "No, I mean the way of expansion, and the radio signal we receive is a deceleration signal from the sub-light speed of the alien fleet, using the reflection of the stars, and we don't do that?" ”

"You mean that a fleet of alien civilizations is approaching us?" The cluster leader asked.

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

"That's what it means." Subject's affirmative response.

All had to be considered for the worst, and after combining the current intelligence, the gatherers agreed that this was an alien civilization with similar technology.

The contact of civilizations is also the contact of the wild, often accompanied by war and killing, this is something that the gatherers learned from the history of the Serenes, so they did not dare to slack off, and immediately decided that the other side would launch an attack on the colonization clusters in the star system, and the gatherers needed to prepare for the coming war,

Preparations for war are in full swing, and they have been mobilizing resources since they learned that an alien fleet was on their way to colonize the Gatherers' star system.

They don't know if the alien fleet is friend or foe, so they can only plan for the worst, assuming that the alien fleet intends to invade their colonial star system.

"Quick! Get ready for battle! ”

The cluster leader urges in the channel, and the other members of the clan will also explain the problems that arise one after another to the cluster leader.

"Antimatter! Antimatter resources are not enough! ”

"The output of antimatter has been increased, and other industrial giants have been suspended, and the production of antimatter giants has been fully produced!" According to the problem, the leader of the cluster gave an order to his clan, and then thought of another possibility in the later stages of the war, and issued a mission to his fellow clan of star communication.

"Ask for help from other colony stars! Tell them that there are not enough resources for war on our side! It is likely to be defeated, so be vigilant! ”

"Understood!" The family in charge of stellar communication answers.

Subsequently, the cluster leader began to focus on other aspects of the matter.

"How's the battle plan going?" The cluster leader asked.

The gatherers who were working on the battle plan replied.

"We have already figured out that by sticking to the star system, we have more resources than the other party, and we have the time and space to deploy them, and we can transform the colonial star into a positional battlefield."

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

"At worst, we're crushed by their technology, and if that's the case, we're going to create a supernova explosion and drag them to death with us."

The gatherers also took into account the gap in technology, not to mention the current star system, because it had not been long since the colonization, there were not a few planets dismantled, the number of antimatter giants was not enough, and the antimatter reserves were not much, so the antimatter resources to arm the leaping creatures were also insufficient.

So, the gatherers feel that they are at a great disadvantage.

"Of course, it is not known whether this method of ending up together will be effective." The gatherers who made the battle plan added.

The leader of the cluster replied, "It doesn't matter if it's useful or not, use it if you feel useful, this alien civilization can sail across stars just like us, and we should be as cautious and overestimated as possible, understand?" ”

"Got it."

After receiving the affirmation of the group leader, the gatherers who formulated the battle plan began to explain the battle plan in depth.

"Then we should do this, arrange a focused array in the orbit of the star, and then broadcast the signal daughter in the star system to lock on to the enemy fleet with higher accuracy, and create a large number of mothership biological ......"

"Wait, are mothership creatures still useful?" The cluster leader asked.

"A large number of mothership creatures can provide cover for the leaping creatures, and the other party will miscalculate our strength and kill them by surprise."

"This is not their home turf, 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 will have more advantages."
