At this moment, inside Shitong Fortress.

With a burst of applause, humans and the Underground Alliance officially established diplomatic relations!

The development purpose of "stimulating turmoil and raising purity, uniting and cooperating, jointly maintaining peace, and jointly promoting development" has finally been established.

"Click, click" the camera kept taking pictures. Professor Lu Tiantian made a temporary guest appearance as a reporter. He also had to write news reports and send them back to the rear... Well, don't think that the reporter's profession is not important. The vast number of people in the Sky City Concerned!

This cooperation is divided into three items: The first is to establish a radio communication system to facilitate future communication work.

Humans need to settle here for a period of time to replenish the bottomed-out petroleum and coal stocks.

In addition, the expansion of Sky City and the expansion of population will also take time, and it will be difficult to achieve without 10 years of effort. Therefore, it is natural to have good communication with neighbors.

The second is the trade of materials. The Underground Alliance has accumulated a lot of resources over the years.

In addition to extraordinary mushrooms, there are also various underground ores and some Zerg derivatives.

Most of the output of the Zerg, such as carapace, compound eyes, flesh and blood, etc., are of little value.

But occasionally, they will produce some precious things.

For example, a "worm yellow" substance is found in the body cavity of a certain insect. It has the effect of clearing away heat and detoxifying. The probability of its occurrence is about one in a million! Most spiritual toxins can be eliminated!

Over the past hundred years or so, the Underground Alliance has accumulated a lot of "worm yellow".

There is also a Zerg bodily fluid called "blue blood", which is an excellent glyph material and has a small amount of healing and life properties.

There is also the "slough of ancient insects", which is simply shocking to the experts on strange objects on the human side.

Ordinary insect shells are mottled with ideal ingredients and difficult to use.

But the level of "Ancient Insect Slough" is really too high. It is actually an excellent grade material?

"This may be anomaly-level material!"

"And the level of this vision is not low..."

All in all, it is definitely a good choice to exchange what is needed.

Even when the Spaniards first landed on the American continent, they first traded in local specialties. Later, they found that the natives were too wealthy, so they launched an aggressive war... Well, humans think that they don't need to be jealous of each other's wealth. , at most it’s just a small amount of money.

As for the third item, it is naturally the exchange of information...

"Our human civilization has a long history and extensive knowledge. Naturally, we know a lot of confidential information."

"From the epochal disaster to the Zerg breeding methods, we all know something..."

"But the price of knowledge is also divided into three, six or nine levels. I don't know what you need here. We are innocent, treat others sincerely, and our friendship will last forever."

"What's more, there are people from different civilizations living in our city... We have never had any conflicts for so long."

The human diplomats began to sell, and they skillfully took out a tablet computer, which displayed a list of items that had been prepared long ago.

There is also a video of the ratman craftsman showing his face to increase credibility.

The human soldiers behind him were as serious as ever and didn't say a word.

Only Professor Lu Tiantian stroked his forehead and wondered how the words "Human civilization has a long history" came out. He sighed in his heart that there are more and more evil-minded people, and human beings are indeed slowly maturing.

The general of the Underground Alliance, Steel Oshima, was also tense and was concentrating on reading this catalog.

He couldn't understand human language for the time being, and most of the content was presented in the form of pictures.

"Aura Value System", the first picture made him hold his breath and his heart almost stopped!

He glanced at the human vaguely.

He deeply knows how important this knowledge is to the development of spiritualism!

Humans are so generous and just take it out?

The diplomats on the human side seemed to notice their doubts and explained with a smile: "This information is the prerequisite for fair transactions between both parties."

"If your alliance can't even figure out the price, the efficiency of the transaction is really low. We have to negotiate for a long time on every little thing."

"What we are pursuing here is fair trade, which is based on voluntary consent of both parties and will never be defrauded or deceived."

He paused and then said: "Of course, if you have doubts, you can exchange knowledge for knowledge. For example, your blacksmithing knowledge is quite attractive to us... We are willing to start

Offer a high price."

Good guy, really good guy!

I want our gear heritage as soon as I open my mouth!

Oshima Steel's spirit, which had just relaxed, immediately became tense again.

He thought fiercely in his heart: "What kind of spiritual value system... We have been trying to figure it out for hundreds of years, but we may not be able to put it into practice!"

But he also knows very well, isn’t hundreds of years of exploration just time?

You still have to buy what you need to buy.

"Oh, let's take a look again."

"How to promote extraordinary fire to level six", "On the relationship between legendary equipment and the destiny of civilization"...

"Overview of 'Field' - Lu Yuan explains the combination of form techniques and qi techniques"

Every piece of information was like a bombshell, which made his mental state slightly unstable, his breathing gradually became heavier, and he wanted to exchange his family's secrets immediately!

Anyway, it's just an exchange of knowledge, and you won't lose anything.

"Level 6...Level 6 fire? What's going on?"

Even the alliance council at the rear was a little confused. They originally thought the opponent was level four, but it turned out to be level six or even level seven. Isn't this bullying the small?

There is also a brand new term "field". What is "the combination of form skills and air skills"? Or is it a paper written by the master who created the legend on the spot?

Just these keywords made them think a lot.

Many scientists have developed a strong desire to buy, and their heads are spinning. But they have too few chips in their hands, so what should they do?

Either sell the ancient insects and get a good price?

…

And humans are not in a hurry, using knowledge to make money is a waste of money!

In negotiations, whoever shows more urgency will always give up more benefits.

Thinking back then, Shumiba Civilization used knowledge to make them a lot of money... When they thought of that white aura being used for nothing, everyone couldn't help but feel heartbroken.

Now, I finally caught a rookie alliance and made all my capital and profits back!

Don't say we cheated you, it's a win-win! Humanity wins twice!

However, there were some minor disagreements within the human diplomatic team. "Don't be too greedy... That's almost enough. There's no need for bottomless exploitation..." Lu Tiantian looked at them with green eyes.

With such a look, he couldn't help but complain, "I always feel that this is not good."

"This is not greed, but the interests of civilization above all else... We must fight for the interests of all mankind!"

The expert who specializes in negotiation is named Fu Yi, a survivor of the Mandala Empire.

Because of his "translation skills", he is a battle-hardened negotiator.

Lu Tiantian sighed: "Is there a big difference between 500% profit and 550% profit? Selling this knowledge will not make us weaker, and the other party is not a civilization that is too rich and cannot afford too many things.

.”

"The price is too high, which scares others away. Many good things are not willing to be taken out, and you think others are stupid... When they buy "Ling Yun Value System", they will soon be able to evaluate how much they have lost."

"If the Underground Alliance is willing to accept this price, what does it have to do with you?" Fu Yi said bluntly, "To put it harshly, you are called a good person!"

"Why does it have nothing to do with me?" Lu Tiantian blushed, and his telepathic voice became louder: "I only know that if you squeeze too hard, there will be no repeat customers!"

"After the transaction is completed, people will inevitably criticize you behind their backs. Human civilization is greedy."

"Humanity will not have a good reputation, let alone receive any gratitude."

Fu Yi couldn't help but snorted: "What's the point of gratitude and fame? You don't think we will settle here forever, do you? It's just a one-time transaction!"

"After separation, we will never meet again, far apart!"

The two sides argued fiercely.

This is the gap in thinking between the old and the new.

The older generation is really extremely depressed and has experienced all kinds of hardships. Even more than 90% of the population of their own tribe has died. After finally catching a fat sheep, they want to kill it and eat it immediately!

The underground alliance is not strong, and it does have a bit of money.

Although the new generation has experienced many disasters, the biggest ghost mist disaster killed thousands of people. Their lives are generally relatively prosperous, so they have a little kindness and righteousness in their hearts, facing the

The weak will inevitably have some sympathy inside.

"But what is the meaning of kindness and righteousness? Tell me the meaning of morality!" Fu Yi was unreasonable.

Even a smart scholar like Lu Tiantian didn't know how to answer this question for a while.

In the end, he thought for a long time and could only whisper: "Think about it, every era does not end well. Perhaps it is caused by this mutual exploitation and harsh confrontation environment... Epochal disasters are really something that a civilization can withstand.

Can we live there? Even if we are the strongest people in the world, so what?"
