At the end of the third sub-light voyage, the sub-light creatures have reached another destination, the star, and at the cost of slowdown, their antimatter reserves have been depleted, but it is still perfectly sufficient to move below the speed of light.

At the beginning of their journey, the third leg of their journey, this star system was a single star system, but a red dwarf, the light intensity was not high, and the number of planets was not large, only two, and both of them were small masses, which was equivalent to three times the mass of the satellites in the gaseous giant orbit in the initial star system.

Planets are formed by the accumulation of gas and debris left over from the birth of stars, and the birth of red dwarfs means that this star system has less material, so there are two planets that are already considered rich in resources.

A considerable part of the resources for the construction of this star system depend on the transportation of resources from other star systems, and they have also organized several resource transportation for this star system at the beginning.

However, such colonization is worth it, and this star system is also a research place for collectors to study how to obtain stellar material up close.

"Welcome to this star system."

"We need antimatter resupply for our next sub-light voyage."

At first, they directly indicated their needs to their compatriots in this star system, and the gatherers in the star system replied.

"Follow this route, go into orbit."

According to the route given by the communication, at first these individuals and antimatter giants are docked, and the first is a single molecule of sharp tentacles that penetrate deep into the interior of sub-light organisms, and through the channels constructed by themselves, the containers that have been depleted of antimatter are taken out, and the full bottles of antimatter containers are replaced, and the whole process is so simple and crude.

When the tentacle is withdrawn, the propped up opening will be healed by the mucus on the outside of the tentacle, so there will be no wound or even a scar, as will the outermost metal bone.

"After you assemble the proton lattice, our antimatter filling becomes very troublesome, and we can only replace the antimatter by stretching out between the gaps between the two proton lattices, and there is no need to use such a biological design, right?"

At the beginning, the antimatter giant complained to them, if it was a sub-light organism in the past, the tentacles of the antimatter giant did not need to find the right position, and they could replace the antimatter by choosing a random place to pierce it, but not now, because the density of the proton lattice is more than the radius of the hydrogen atom, and it is impossible for the tentacles with a single molecule as the head to pierce this proton lattice, the density is too great.

"This is a standing strategic material, which is convenient for the rapid formation of combat effectiveness in a timely manner during combat."

"Proton lattices, like antimatter, are products that cannot be processed from cells, and require a giant structure like yours to make them, and if there is an enemy, and it is equal to our strength, and the battle is fierce, then we are likely to face a situation where proton lattice is in short supply."

"The will has said that you must know how to be prepared for danger in times of peace, and to be born in sorrow and die in peace, and the same is true of you antimatter giants who are constantly making and storing antimatter."

The first group of gatherers gave an explanation, which was the collective idea of their group of gatherers.

"I see."

"And where are you going next?"

The antimatter giant continued to ask, just like the collectors of other star systems before him.

"A binary star system nine light-years away."

"There are obstacles on the route to get there, you need to be prepared, it will be dangerous in this state."

The antimatter megastructure reminds these fellow families that the gatherers stationed in the star system are not only tasked with the production and exploitation of resources, but also with the task of observation, and that it is necessary to explain the danger of sub-light shipping routes as they do now, which is why they ask where they are every time they first arrive in the star system.

Of course, even this does not ensure 100% safety of the route, if it is a small-mass wandering black hole that is difficult to observe, or a relatively small and sparse number of wandering meteorites, these are very difficult to find, and the organisms in the sub-light state can only fend for themselves.

"What kind of obstacle?"

At first, he was vigilant, and an obstacle in a sub-light state, even if it was just a cloud of gas, was extremely dangerous.

The antimatter giant replied with a more glad mood.

"A large plasma-like high-temperature nebula, ejected from a supernova explosion 70,000 light-years away, is fortunately far enough away from us."

A supernova explosion is a light-year cosmic disaster, which can directly kill a few light-years to more than 20 light-years in the range, and the area directly affected by the supernova will become a dead domain.

"How big is that nebula?" Another collector asked.

"In the range of two to three light years, there are errors in astral measurements."

The antimatter giant thought about it, but only gave an approximate value, and the distance at the level of light years is too far, plus the gravitational interference of the stars and the speed of light limitation, it is impossible to answer an accurate value.

"It's not very big, we can go straight through it in a sub-light state"

"Don't talk nonsense if you don't understand, the nebula will make us fall out of sub-light speed, even if we have the ability to pass through the nebula, the accumulated high temperature may roast us collectively, and heat dissipation in a vacuum environment is a big problem."

Before the collector could finish speaking, he was immediately refuted by the other fellow collectors.

"That's right."

After thinking about it, the refuted gatherers also understood that the antimatter shield in front of them would make contact with the nebula, which would cause the annihilation of positive and antimatter to occur, and then they would also slow down.

After realizing this, the gatherers were also afraid.

At first, they began to obtain materials from their peers in the star system for the transformation of organisms, adding an additional batch of solid helium for cooling and cooling, and then a vacuum insulation design, vacuum is an excellent thermal insulation layer, and the only way for heat to propagate is thermal radiation.

"Why, then, did that star explode 70,000 light-years away?"

The collectors who were waiting for the completion of the modification of the organism asked such an inquiry, and this question also aroused the curiosity of the collectors.

"It should be that the supergiant reached the end of its lifespan, and then there was a supernova explosion."

"No, not necessarily, maybe a civilization uses a black hole bomb, as long as it can mass-produce antimatter, the black hole bomb has the ability to make it, or if you make a black hole in other ways, you can also achieve an artificial supernova explosion."

The gatherers were discussing with each other, initially trying to get answers directly from the antimatter megastructure.

"What are your observations?"

"I don't know, when we started looking there, the remains of the supernova explosion already existed, and the supernova explosion occurred at least 200,000 years ago."
