On Secret Net, a routine gathering between Luo Jia, Black Sword and Lan Yu is underway. As time goes by, they continue to exchange experiences and experiences, and their three views collide with each other, gradually producing a chemical reaction called friendship.

Especially at present, the Galen Empire's soldiers are approaching. Such a gathering is particularly important to Luo Jia, because he must have enough information and solutions to deal with the opponent's powerful invisible technology before the war begins.

Lan Yu smiled and shrugged, "In this world, if I could only choose one plant, I would choose algae without hesitation. Although algae are not the most powerful plant, they are the most practical."

"If a starship sailing is built with a strong enough algae ecosystem, it can use its crazy reproductive ability to form a delicate biological balance. The spacecraft waste is put into the pool and is purified by the algae to form oxygen and food. Humans consume oxygen and food, and the waste is circulated by the algae again."

"In this way, the spacecraft can sail in the universe for a long time, and there is no need to worry about oxygen, moisture, and replenishment. Even the fuel required for navigation can be synthesized through algae, but the efficiency is not too high and cannot be compared with planetary mining."

Hearing Lan Yu's words, Black Sword felt very magical. He swallowed heavily and said, "According to your opinion, emotional algae are all advantages and no defects at all?"

Lan Yu shook his head gently, "There has never been a perfect existence in the world. Of course, algae have shortcomings. For example, you have to be more good at cooking to make algae food delicious. If you lack the talent for food and eat 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 light. Secondly, we are good at planting. All plant civilizations have starships and colonial planets, which are rich in resources."

After hearing this, Luo Jia frowned slightly and asked curiously: "What do you mean is that seaweed can also be used in planet transformation projects?"

"Of course," 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 drought, we will use weeds. Anyway, whether it is algae or weeds, they all have the characteristics of strong reproductive power and tenacious vitality."

"As far as I know, energy civilization also has its own planet transformation plan, Black Sword, is that true?" Lan Yu asked Black Sword.

The Lanyu family has been working as a garbage guard for generations and has collected many strange items and many strange information. So, although Lanyu comes from plant civilization, it is very knowledgeable and is a master of everything.

Black Sword nodded and said, "Well, major civilizations have corresponding technologies for transforming planets. After all, civilizations always need to expand, and expansion is inevitable to open new colonies. If you don't know how to transform planets, you can only steal other people's territory. There are too many existences in history that have no strength but occupy the top planets, and they are destroyed overnight. There is no reason. Some people just like their planets. Among the stars, weakness is the original sin."

Knock ~

After hearing this, Luo Jia felt bad. She had a similar crisis in her own small ball-breaking front. Looking at the stars, the small ball-breaking environmental index ranks top, but the Earthlings who occupy the small ball-breaking are not strong, so she was targeted by the Galen Empire. This is probably what the ancients said, "Any man is guilty of being guilty of being a treasure."

After a pause, Black Sword continued: "We also have two solutions. One is to use nuclear bombs to wash the floor, release enough greenhouse gases, and force the target planet to form a greenhouse effect and give birth to plants and oceans."

"The second type is energy chains, which deliver the heat generated by stars in the galaxy to the target planet by artificial transmission chains, heat it, and release water vapor and carbon dioxide."

After listening to the description of Black Sword, Luo Jia and Lan Yu were both stunned. They are worthy of being energy civilization. As expected, they are simple and crude enough. Nuclear bombs release greenhouse gases, or connect planets to the sun, and use the energy released by the sun to heat the target. Even if the planet transformed in such a roughly transformed planet, even if it can live in people, it will probably be riddled with holes on the surface, like a rotten pear.

In contrast, the plant civilization plan is environmentally friendly, but it takes a long time. Assuming the comprehensive energy civilization and the transformation plan of plant civilization should be a good choice, taking into account both speed and environment. If one day transforms Mars, let them both help.

Luo Jia thought absent-mindedly that life still needs friends. During the chat, the future Mars transformation plan was settled. Of course, it was too early to consider these things now. Xiaobiao had to survive the current crisis first.

To be honest, Luo Jia, who inherited robotics, was not afraid of the Galen Empire. With the crazy productivity of the Mechanical Legion, he could complete the explosive mission in the shortest time.

But the key is that the other party has powerful invisible technology, and no one knows when they will arrive and when they launch an attack, which is very difficult. After all, it is said well, invisible enemies are the most dangerous enemies.

"I'm sorry, Mr. Pilot, I've repeatedly checked the database, but I still couldn't find the answer to how to deal with the fleet with invisible technology." Black Sword is an outstanding graduate of the Command Academy. When he saw the pressure hidden in Luo Jia's eyes, he explained with apologies.

Since he learned about the attack of the Galen Empire, Luo Jia was worried. He took the initiative to learn about the invisible technology and how to deal with the invisible technology. This abnormal behavior made the Black Sword and Lan Yu pay great attention to it. After all, in the past days, Luo Jia had never raised any questions, which shows that this matter must be very important to Mr. Pilot.

But unfortunately, invisible technology is not so easy to deal with, neither Black Sword nor Blue Feather can do anything about it.

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

Lan Yu thought for a while, "Mr. Pilot, I have been reading the information collected by the family recently. I noticed such a detail, which may be helpful to you."

"Is that so? Please tell me." Luo Jia said politely.

Lan Yu said: "According to the analysis of an ancient tactical manual, in this world, the most powerful stealth technology comes from quantum civilization. The invisible generators they manufacture based on the principle of quantum entanglement are known as unparalleled in the world."

"But according to the tactical manual, even the invisible technology of quantum civilization needs to be delayed. The invisible must be removed first, and then large equipment, such as warp engines, high-power weapons, etc. As for other invisible technologies with lower levels, the delay is even more serious."

After hearing Lan Yu's words, Hei Jian hurriedly took out a small notebook to record, while Luo Jia looked thoughtful. The invisible system would cause delays, which seemed to be a point that could be exploited.

...

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

After losing contact with the Worker Ant, the fleet commander Mel keenly realized that something was wrong. Although Niedro was cruel, he was a qualified captain with rich experience and had dealt with complex and difficult situations on his own many times. Without special reasons, he would not have been unable to contact him for so long.

"It must arrive faster!" Mel made a decisive move.

"But it is now the fastest speed. If you continue to accelerate, the old-fashioned warships in the fleet will fall behind due to performance reasons." The chief engineer reported to the fleet leader.

The fleet is a huge group, not only with main attack battleships, but also with a large number of reconnaissance ships, electronic warships, logistics supply ships, maintenance dock ships, etc. When cruise, the overall performance of all starships must be taken into account.

Mel bit his lips and said extremely solemnly: "We who live among the stars are like wild beasts in the dark forest, hiding carefully, while looking for prey while avoiding becoming other people's prey."

"The safest way to get along between two civilizations is to never meet. Once the two civilizations encounter, the next step is to fight to the death. According to Niedro, although the earth is not strong now, they have robotics and have great potential for war."

"Can you imagine what will happen next if Nidero fails and is caught by the people on earth?"

There was a dead silence, and after a moment his assistant Kent frowned and said, "At the worst, the Earthlings will know who we are, where we come from, and in the future, send a fleet to our mother star."

The Earthlings counterattacked to their doorstep?

It's so serious?

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

Mel swallowed and said in a deep voice: "Although it is cruel, this is the fate of civilization. Since we have encountered it, then only one of us and the earth will survive."
