In the spirit of not wanting to be in vain, Su Han still accepted the material.

As for whether Tolls can do what he has explained, Su Han also knows in his heart.

Murphy had already fallen due to an accident, and it was impossible for him to be in this world.

Therefore, Thor's calculation was doomed to fail.

In this way, Su Han stayed on the planet Versailles for two more days.

Two days later, the Cosmic Civilization Exchange Conference was held as scheduled.

Because Su Han is not the organizer, he doesn't know how many civilizations have participated in this cosmic civilization exchange conference.

But on the planet Versailles, there are strange creatures everywhere.

Let Su Han understand that there are probably no more than 10,000 civilizations participating in this cosmic civilization exchange conference.

Of course, the Conference on the Exchange of Civilizations in the Universe is not a gathering of representatives of all civilizations in one region to communicate together.

Because there is a gap between civilizations, the four major civilizations deliberately divided this cosmic civilization conference into three regions.

And Su Han's area is the outermost area.

There are almost all the third-level civilizations in the universe here.

Because there are too many civilizations gathered here, even Long Yuanxing is not very outstanding.

"Ladies and gentlemen, today our Benguela civilization has brought a piece of the latest stealth fighter, this fighter can ignore the reconnaissance methods below the level four civilization, it is a necessary weapon for siege, now I will show you the performance of this new fighter."

As he spoke, the creature from Benguela released a new type of fighter jet.

This fighter is not much different from the Dragon Kingdom fighter, except that a special device is installed on both sides of the left wing.

If Su Han didn't guess wrong, it was these two special devices that played a shielding and reconnaissance method.

'Communication' between civilizations of the same rank is very simple.

That is a civilization that puts its proudest technology on display.

Once another civilization is interested in this technology, then the next steps can be discussed with that civilization.

If a civilization is genuinely interested in the technology that the civilization exhibits, an equivalent technology exchange can be used.

If a civilization does not have the same technology, it can also use special materials to exchange.

In a word, if you have a crush on any technology here, you can exchange it, as long as you can open a chip that will make the other party excited.

In just a few moments, the creatures from the Benguela civilization had already displayed their stealth fighters.

As he said, this new stealth fighter can indeed shield any reconnaissance methods below the level 4 civilization.

However, the creatures present did not seem to have much interest in this new stealth fighter.

For a while, no living beings came forward to talk to the living beings from the Benguela civilization.

"Team Leader Su, this new stealth fighter is very close to the one in the Siqin Empire, otherwise we ......"

Hearing Liang Shuang say this, Su Han shook his head and explained in a low voice: "There is no need for this, since we took the Siqin Empire, there has been a huge breakthrough in the stealth fighter segment, and winning another such fighter will not significantly improve the combat effectiveness of our Dragon Kingdom." ”

"We don't have a lot of materials with us this time, let's exchange the technology that will be of obvious help to our dragon country!"

Although Su Han had taken a large number of materials with him before setting off.

But those materials are a drop in the bucket for the Cosmic Civilization Exchange Conference.

There is a saying in the dragon kingdom that money must be spent on the edge of the knife.

For the sake of a new stealth fighter, all the materials were used, which went against Su Han's original intention of participating in this cosmic civilization exchange conference.

Next, several more civilizations came up with their most proud technologies.

However, it couldn't arouse Su Han's slightest interest.

The reason is simple!

The technology that these civilizations have come up with is either something that Long Yuanxing already has, or it is related to life.

It is not very helpful for the current Long Yuan Xing.

Two hours passed.

In these two hours, Su Han had seen various civilizations and had a basic understanding of these civilizations.

But at this moment, the technology taken out by a creature from the Valcam civilization immediately attracted Su Han's attention.

The Valcam civilization is located in the northernmost part of the desert galaxy, and the creatures of this civilization are very unique.

They have the head of a human but the body of a horse, and they are very muscular, and they can run at speeds of up to 60 kilometers per hour.

The centaur-like creature had come up with a potion they called the perfect genetic potion.

At this point, the centaur-like creature was introducing the perfect genetic potion.

"Ladies and gentlemen, this potion is a new potion that was finally developed by the Perfect Valcam civilization after a hundred years of experiments, and I believe everyone here knows that all living beings in the universe can evolve."

"But if you want to evolve perfectly, you must need the help of external forces, and this perfect genetic elixir can help living beings evolve thoroughly......"

After listening to the introduction, Su Han learned that this perfect genetic elixir can help organisms evolve thoroughly, so that all qualities of the body can reach the highest standards.

In this regard, Su Han came to the week in an instant.

Although all the people of the Dragon Kingdom have completed their plans, this evolution is not complete.

However, the current Dragon Kingdom has not made the slightest progress in this regard.

If this perfect genetic potion is what the centaur suggests, it can be exchanged.

Thinking of this, Su Han got up and walked towards the camp of the Valcam civilization.

Walking to Valcam's camp, Su Han smiled slightly: "Hello, I'm Su Han from Longyuan Star, and I'm very interested in the perfect genetic potion you just showed, I wonder if you can introduce it to me again." ”

The creatures of the Valkam civilization saw that the introduction just now had an effect so quickly, and at the same time, they were overjoyed, and at the same time, they quickly stood up and introduced to Su Han: "This gentleman, the perfect gene potion we have mastered can help promote the potential in the spirit body, so as to achieve the purpose of thorough development, if you are really interested, we can hand over the recipe for the perfect gene potion to you, but ......"

Although the other party did not finish his words, Su Han understood what the other party meant.

In order to perfect the formulation of a genetic potion, it must be exchanged with the same technology or enough materials.

Su Han thought about it, he happened to have a mecha technology related to a third-level civilization here.

Since the Valcam civilization pursues the ultimate power, it should not refuse such a deal.
