The secret net, Luo Jia's routine gathering with Black Sword and Blue Feather is underway, and as time goes by, they continue to exchange experiences and insights, and the three views collide with each other, gradually producing a chemical reaction called friendship.

Especially at the moment, when the Galen Empire's troops are overwhelmed, such a gathering is particularly important for Luo Jia, because he must have enough information and a plan to deal with the opponent's powerful stealth technology before the war begins.

Blue Feather smiled and shrugged, "In this world, if I had to choose only one plant, I would not hesitate to choose algae, although algae is not the most powerful plant, it is the most practical. ”

"In a starship that travels long distances, if a strong algae ecosystem is built, it can use its crazy reproduction ability to form a delicate biological balance, and the ship's waste is put into the pool, which is purified by the algae to form oxygen and food, and humans consume oxygen and food, and the waste is recycled by the algae again."

"In this way, the spacecraft can sail in the universe for a long, long time, without worrying about oxygen, water, supplies and the like, and even the fuel required for navigation can be synthesized through algae, but the efficiency is not too high, and it cannot be compared with planetary mining."

Black Sword listened to Lan Yu's words, and felt very magical, he swallowed heavily and said, "According to what you mean, emotional algae are all advantages, and there are no defects at all?" ”

Lan Yu shook his head slightly, "There has never been a perfect existence in the world, of course algae also has shortcomings, for example, you have to be more good at cooking in order to make algae food delicious, if you lack culinary talent, gnawing seaweed cakes year after year, it will make people crazy, of course, for our plant civilization, food has never been a problem, first of all, our eating habits are already light, secondly, we are good at planting, all the starships and colonized planets of plant civilization are rich in melon and fruit paradise." ”

Hearing this, Luo Jia frowned slightly, and asked curiously: "You mean, seaweed can also be used for planet transformation projects?" ”

"Absolutely." Lan Yu said: "We have two plans for planet transformation, if the target planet has abundant water resources, we will use algae, if it is relatively arid, we will use weeds, anyway, whether it is algae or weeds, they have the characteristics of strong fecundity and tenacious vitality." ”

"As far as I know, the energy civilization also has its own planetary transformation plan, Black Sword, isn't that so?" Lan Yu asked Black Kendo.

The Blue Feather family has been a garbage guard for generations, and has collected a lot of strange items and a lot of strange information, so Blue Feather doesn't look like it comes from a plant civilization, but he knows a lot and is a jack of all trades.

Black Sword nodded and said: "Well, the transformation of the planet, the major civilizations have the corresponding technology, after all, civilization always has to expand, and expansion is inevitable to create new colonies, if you don't know how to transform the planet, you can only grab other people's territory, there are too many existences in history that have no strength, but occupy the superior planet, and they will be wiped out overnight, for no other reason, someone has taken a fancy to their planet, among the stars, weakness is the original sin." ”

Gurgle~

When Luo Jia heard this, he was in a bad mood, his own small wrecking ball was in a similar crisis, looking at the stars, the environmental index of the small wrecking ball ranked at the top, but the earthlings who occupied the small wrecking ball were not strong, so they were targeted by the Galen Empire, this is probably what the ancients said, the puffer is not guilty.

After a pause, Black Sword continued: "We also have two plans, one is to use nuclear bombs to wash the ground, release enough greenhouse gases, force the target planet to form a greenhouse effect, and promote the growth of plants and oceans. ”

"The second is the energy chain, which uses artificial conveyor chains to deliver the heat generated by the stars in the galaxy to the target planet, heats up, and releases water vapor and carbon dioxide."

After listening to the description of the black sword, Luo Jia and Lan Yu were dumbfounded, worthy of energy civilization, it was really simple and rough enough, the nuclear bomb washed the ground and released greenhouse gases, or connected the planet with the sun, and used the energy released by the sun to heat the target, such a rudely transformed planet, even if it can live in people, I am afraid that the surface will be full of holes, like a rotten pear.

In contrast, the plant civilization scheme is environmentally friendly, but it takes a long time, assuming that the transformation scheme of the comprehensive energy civilization and the plant civilization should be a good choice, taking into account the speed and environment, and if you want to transform Mars one day, let the two of them help.

Luo Jia thought absentmindedly, life really needs friends in the world, and in the midst of chatting, the future Mars transformation plan will be settled, of course, it is too early to think about this, and the little wrecking ball must survive the current crisis first.

Speaking from the heart, Luo Jia, who inherited the robot technology, is not afraid of the Galen Empire, and with the crazy productivity of the mechanical legion, he can complete the explosive mission in the shortest possible time.

But the key is that the other side has strong stealth technology, and no one knows when they will arrive and when they will attack, which makes it very tricky, after all, as the old saying goes, the invisible enemy is the most dangerous enemy.

"I'm sorry, Mr. Navigator, but I have searched the database repeatedly, but I still haven't found an answer on how to deal with a fleet with stealth technology." Heijian was an outstanding graduate of the Command Academy, and when he saw the hidden pressure in Luo Jia's eyes, he explained apologetically.

Since he knew about the attack of the Galen Empire, Luo Jia was worried, he took the initiative to learn about stealth technology and how to deal with stealth technology to Blue Feather and Black Sword, this abnormal behavior made Black Sword and Blue Feather attach great importance to it, after all, in the past days, Luo Jia has never taken the initiative to raise questions, which shows that this matter must be very important to Mr. Navigator.

But unfortunately, stealth technology is not so easy to deal with, whether it is Black Sword or Blue Feather, there is nothing to be done about it.

"Due to the annihilation of civilization, the technological level of our energy civilization is far inferior to before." Black Sword explained.

Lan Yu thought for a moment, "Mr. Navigator, I've been reading the information collected by the family recently, and I noticed such a detail, which may be helpful to you. ”

"Really? Please speak. Luo Jia said politely.

Lan Yu said: "According to the analysis of a set of ancient tactical manuals, in this world, the most powerful stealth technology comes from the quantum civilization, and the stealth generator they made based on the principle of quantum entanglement is known as the unparalleled in the world. ”

"But according to the tactical manual, even the stealth technology of the quantum civilization needs to have a delay, and the stealth must be lifted before you can use large equipment, such as warp engines, high-powered weapons, etc., and as for other stealth technologies of lower levels, the delay is even more serious."

Listening to Lan Yu's words, Black Sword hurriedly took out a small notebook to record, while Luo Jia looked thoughtful, the stealth system will cause delays, it seems that this is a point that can be exploited.

……

In the dark starry sky, the integrated fleet of the Galen Empire is approaching the solar system at full speed.

Fleet Commander Mel was keenly aware that something was wrong after losing contact with the Worker Ant, and that Niedro, despite his cruel personality, was a qualified captain with a wealth of experience and had dealt with complex and difficult situations on his own, and he could not have been uncontacted for so long without a special reason.

"Gotta get there sooner!" Mel cut the railroad.

"But now it's the fastest speed, and if you continue to accelerate, the old warships in the fleet will fall behind due to performance reasons." The chief engineer reported to the captain of the fleet.

The fleet is a huge collective, not only the main attack battleship, but also a large number of reconnaissance ships, electronic warfare ships, logistics supply ships, maintenance dock ships, etc., when cruising, the overall performance of all starships must be taken into account.

Mel bit her lip and said with unusual solemnity: "We who live in the stars are like beasts in the dark forest, carefully hiding, looking for prey while avoiding becoming the prey of others. ”

"The safest way to get along between two civilizations is to never meet, once the two civilizations meet, the next can only be a life-and-death war, according to Niedro's description, although the earth is not strong yet, they have robotics and have great war potential."

"Can you imagine what would happen next if Nidro failed and was captured by the earthlings?"

There was a dead silence, and after a while, the assistant Kent frowned and said, "At worst, the earthlings will know who we are and where we come from, and in the future, send a fleet to our home planet." ”

Earthlings counterattack to the doorstep?

How serious is it?

Everyone was stunned and showed surprised expressions, but considering the war potential of the earth, they had to admit that the earth had the possibility of riding the Galen Empire.

Mel swallowed a mouthful of spit and said in a deep voice: "Although it is cruel, but this is the fate of civilization, since it has been encountered, then only one of us and the earth can survive." ”

"Pass the order, drop all the starships that are underpowered, and the rest of the ships will follow me and go at full speed!"
