Jiang Li'an introduced the characteristics of the major races one by one, blue skin, red skin, gray skin, as well as the Sartre and Snow Spirit tribes that are extremely similar to the human race, with tails, horns, and even the Water Spirit Clan with dual respiratory organs.

Everyone present felt that it was enjoyable, and some even took notes.

"The human race can only rank second to last among all races, and for millions of years, the major races have sacrificed their lives and sacrificed trillions of soldiers to barely keep the four living planets." Jiang Li'an waved his hand, and another life race appeared beside him, "This is the Bama people, who live in the Bama galaxy 86 million light years away from the earth, they are the sworn enemies of the interstellar alliance and the culprits of the interstellar war. ”

"Trillions of soldiers?" Someone was surprised, "The warriors sacrificed so much, and the ordinary people are not more?" ”

"I didn't expect the Terrans to be the second-to-last." Someone had a gloomy look.

"Are there any other alien races?" An old man asked.

"There were, and now it's extinct."

The Bama people rule over dozens of living planets, and the aborigines of some planets have long been extinct, and even the wolf Tuxing people have only a few million people left, and they may become extinct one day in the future.

"Exterminated ......," the old man muttered to himself, and the others fell silent.

Jiang Li'an was very satisfied with the on-site effect: "After introducing aliens, let's talk about weapons and technology, most of the people present probably like this topic very much." ”

It's still a simulation method, from the lowest-level laser gun all the way to the railgun, from the Chijin-class battleship all the way to the space fortress.

"There are many more such as holographic projection, long-distance communication, wormhole jumping, protective shields, biological dormancy, memory transmission, advanced artificial intelligence, antimatter extraction and utilization, and so on." Jiang Li'an spread his hands, "The conditions are limited, and I haven't mastered most of these techniques, so I won't demonstrate them to you." ”

Every time he said a technology, the eyes of most of the people present lit up, and when they heard the wormhole jumping and antimatter extraction and utilization, it was more like they wanted to emit light.

"It's okay to tell me what you know!" A balding middle-aged man said.

"Huh?" Jiang Li'an's face changed, and he looked at the bald middle-aged man, "Why should I tell you?" ”

Zhou Limin saw that the situation was not right, and hurriedly said: "Xiao Jiang, he is also unintentional, you continue." After speaking, he glared at the bald middle-aged man.

Jiang Li'an frowned, it is extremely difficult for the earth to maintain peace and development, although there are occasional disputes now, but at least there are no large-scale wars.

Everything I say is to make these people retreat, but the more you talk, the more it can arouse people's curiosity, which is counterproductive.

"Okay, I'll say one more thing!" Jiang Li'an pursed his lips, "Why did the human ancestors abandon the earth and develop alone? ”

"Didn't you say that the earth left because it ran out of resources?" Someone replied.

"You only know that material is a resource, so do you know that life is also a resource?"

"Lifespan is also a resource?" Someone was surprised, "What do you mean?" ”

"I have participated in many interstellar wars, and it took me nearly two years just to travel, and if I want to explore the universe, a flight may be hundreds of years, or even hundreds of years, without enough lifespan, everything is empty words."

"Most people on the earth can only live to be seventy or eighty years old, such a short lifespan, just accumulating knowledge will take most of the time, and when you have accumulated enough, people are old, and you still need the same amount of time to pass on the knowledge you have learned to the next generation."

"Knowledge can change everything, without knowledge, without inheritance, rely on computers to automatically research new technologies?" Jiang Li'an glanced around, and below him were a pair of eyes eager for knowledge, "The ancestors of the human race millions of years ago had a long lifespan, with an average of more than 500 years, while modern people only have a few decades, and the reason is ......"

When it comes to lifespan, no one is not moved, how many emperors in history have eaten lead and swallowed mercury in order to live forever, and there are legends of qi refiners and cultivators everywhere, in the final analysis, they still don't want to die, they can only enjoy when they are alive, and they have nothing when they die.

Only the poor and destitute feel that life is better than death, but all the rich and powerful do not want to die, and now there are many rich people who invest in life sciences, throwing a lot of money into it every year, in order to hope to research something and improve their lifespan.

"Nearly 3 million years ago, there was a strange radiation energy in the Milky Way, which could greatly increase the lifespan of the human race, but unfortunately, in the following tens of thousands of years, the environment changed abruptly, and the radiation energy was greatly depleted, without this energy, the Milky Way is equivalent to a cage, and the earth is a cage within a cage!" Jiang Li'an didn't have an appetite, and finished speaking in one breath.

"Boom!"

These words were like a thunderbolt from the sky, bombarding everyone's minds.

"Impossible!" Someone questioned, "You also went out from the earth, so you are not afraid of lack of life?" ”

"I'm afraid!" Jiang Li'an spread his hands, "So I'm leaving the earth, soon, just these two days." ”

"Wait, you mean you can increase your lifespan as long as you get out of the galaxy?" A scholar-like man asked.

"Well, so to speak, but there are conditions." Jiang Li'an continued, "First of all, we must obtain the citizenship of the alliance, and secondly, we must obtain the qualification to live on a living planet, and living on a living planet can change genes and inherit for three generations. ”

"Do you all live on a living planet?" The scholar-like man asked.

"My wife lives on the planet of life, and I don't." Jiang Li'an smiled helplessly, "I'm just a private, and I'm almost like an ordinary citizen in the Interstellar Alliance, so how can I be qualified to live on a living planet." ”

The eyes of everyone present instantly focused on Lin Yuechi, and Lin Yuechi noticed something strange, and his pretty face turned red.

"Don't look at her, she doesn't have the authority to arrange for people to live on living planets." Jiang Li'an raised his voice, "There is only one way for ordinary people to increase their lifespan, as for the elixir and genetic modification, just think about it, there is everything in your dreams." ”

"Aren't you also ordinary people?" A middle-aged man with the Mediterranean Sea on his head asked.

"Well, you might have a misunderstanding of me." Jiang Li'an glanced at the person who spoke, "We husband and wife dare to come here empty-handed, do you think we are ordinary people?" ”

"Ordinary people will be taken away from Earth by aliens?"

"Ordinary people would go to an interstellar war?"

"Would ordinary people be qualified to stand here?"

The soul asked three times, and the Mediterranean shrank back stupidly.

"Do you think the race of life I just showed is a holographic projection, fake?"

Jiang Li's peace of mind moved, the pitch-black battle armor covered his whole body, and soon more than a dozen doppelgangers came out of his body, exactly like himself, standing in a row in the open space behind the podium.

"You can let the warriors outside try my clones to see if they are fake, or you can do it yourself."

"Xiao Jiang, what are you doing, no one questions your ability, put it away." Li Weiguo played a round game.

"Humph!" Jiang Li'an withdrew the element and sneered: "The most terrible thing in this world is ignorance, I always think that I am no worse than others, even if I see it, I will not admit it." ”

"You ......" Mediterranean blushed, and he didn't hold back the second half of the sentence for a long time.

"The set of battle armor on my body is called 'Life Armor' and 'Elemental War Armor' in the Interstellar Alliance, the function is similar to that of a liquid metal robot, invulnerable, invulnerable, invulnerable, even if the nuclear bomb explodes, I can't die, ten thousand times stronger than the combat suit and spaceship I parked outside, this is the reason why I was chosen."

Jiang Li'an understands that these people will not stop if they don't give some dry goods.

"If you want to have this armor, you must first meet one condition." Jiang Li'an pointed to his brain, "Only those with a spiritual scale value of more than 3 are qualified to control this set of battle armor, with this set of battle armor, people can survive in outer space, and they can also take the initiative to absorb radiation energy to improve their physical fitness and lifespan." ”

"There are about 20 people on the earth who meet the conditions every two years, and it has continued to decrease in recent years, and only if they meet this condition, they can leave the earth to fight on alien planets."

There are 7 billion people on the earth, and less than 10 people are eligible every year, which is equivalent to 1 in 700 million.

"Ordinary people can't get the citizenship of the Interstellar Alliance, let alone live on a living planet, even if the Earth develops into an interstellar civilization again and leaves the galaxy, the lifespan will not be improved."

"The population of the Interstellar Alliance is trillions, and there are only 4 living planets, and there are rich planets among the Bama people, but if you want to be slaves, you can also go."

"Then aren't we going to be trapped here, and there's nothing we can do?" Someone got up and asked.

"There is a way, unless you first unify the earth, and then find an ownerless planet of life to immigrate to, of course, you have to have the strength to defend it." Jiang Li'an continued, "Living planets are extremely rare, each of them is the target of alien races, and the snake swallowing elephant is just sending it to death. ”

"Why do you want to unify the Earth?" Some people are puzzled.

"It's okay if it's not unified, as long as you don't grab the resources of other countries, and you have the strength to resist the nuclear weapons of other countries, the most important thing is not to leak secrets." Jiang Li'an looked at the person who spoke with the eyes of the second fool, "Satellites are flying all over the sky, spies are running everywhere, I can be discovered by you, do you think you can hide and not be discovered by others?" ”

In the information age, nothing can be hidden, the whole world is infiltrating each other, and projects that have invested a lot of effort and money are copied as soon as the results are produced, so that most countries do not have scientific research institutes at all, and even if they do, they are all prepared for plagiarism or imitation.

It often takes years to decades for a high-tech project to go from launch to fruition, and sometimes too much investment can even bring down a country.

But often these achievements will be easily taken away by spies or undercover agents, and the cost of cultivating a spy or undercover agent is not worth mentioning compared to the project itself.

After obtaining these results, it only needs to be slightly modified, and it can be said that it is independent research and development, or innovation.

"Okay, I've said everything I need to say." Jiang Li'an clapped his hands, "The spaceship and combat suit are outside, you have one night to study the replication, if you can research the alternative, it means that you can also enter the interstellar civilization." ”onclick="hui"
