As the liaison base of Myriad City in this Blood Desolation Realm, its main function is to settle the merit points in this battlefield world, convert the merit points into combat effectiveness in a timely manner, and help the creatures of Myriad City improve their combat power.

In this liaison base, the core area is naturally the exchange hall.

And with the exchange hall as the central area, the creatures of the Ten Thousand Realms and the indigenous creatures of the Blood Desolation Realm will also set up the most primitive stalls here.

Slowly, each of the contact bases of the Ten Thousand Worlds City will develop into a commercial area.

When Gu Xuan came here, it happened to be the most lively morning time of the day, like a small town-like liaison base, at the moment it was like a market, full of stalls, all kinds of strange creatures, like a carp crossing the river, looking for the items they needed.

"You have entered the Ten Thousand Realms City Liaison Stronghold and Commercial Area, please do not disrupt the order of the Commercial Area, otherwise you will be punished extremely severely."

Just as Gu Xuan stepped into it, he unexpectedly received a warning from the Ten Thousand Worlds City system.

However, after thinking about it for a while, Gu Xuan also understood that if it weren't for the protection of the Ten Thousand Realms City System, this place would never be as prosperous as it was now.

After all, in the absence of absolute order, it is impossible for the strong to rely on self-discipline and not plunder the resources of the weak, just as it is impossible to ask a tiger not to eat meat.

Even Gu Xuan, after learning that this area was under the maintenance of the Vientiane City system, he instantly felt a sense of stability in his heart, and the idea of visiting the various stalls was even stronger.

It is forbidden to fly, to buy and sell, to rob, to steal, and to harm other living beings.

Creatures who want to set up a stall can take the number and wait in line for the stall owner in front of them to close the stall, and then they can set up a stall according to the number, and a stall can be used for 12 hours.

The booth is free, and if you run out of it, you have to wait for ten days before you pick up the number.

These were the basic order of this Ten Thousand Realms City's liaison base, and when they received the warning prompt, they were also sent to Gu Xuan.

Under the circumstance of prohibiting flight, Gu Xuan would not feel how special he was, and he had to challenge the order here.

Therefore, Gu Xuan followed the bustling crowd, looking east and west on the stall, and walked towards the exchange hall in the most central area.

"The three-tailed cat demon clan can be used as a pet, a mount, and a maid, don't miss it when you pass by~ Buy 3 get 1 free, buy early and enjoy early~"

"Dragon-level treasures, take a look, so that from now on King Kong will not be broken, and all things will not invade!!"

"Dragon-level secret method, many cheats, bookstore clearance sale, the last 5 hours, the last 5 hours, directly break the bone!"

“…………”

It is said that it is a stall, but in fact, a small space circle is placed, as long as you enter from the entrance of the stall, there is a trading hall with a unique cave.

It can not only store goods better, but also be more private, ensuring the privacy and safety of buyers and sellers.

However, this also has a disadvantage, that is, you can't directly perceive and view the goods, and you can only check whether it is the item you need according to the images and item information provided by the seller.

Like what Gu Xuan needs most now, the items with the origin of the world, must be perceived in person, and even need to be held in the hand to be close to the touch, before they can be discovered.

It is impossible to determine whether or not there is a World Source based on the image and information of the item alone.

Yes, from the entrance all the way to the entrance of the exchange hall, Gu Xuan only found a stall that said that there was a certain world, the strange stone of heaven and earth when the world first opened, so he went in and took a look with the mentality of trying it out.

As a result, there was no trace of the origin of the world on that stone, it was really just a strange stone with a unique aura and an unknown effect.

Moreover, even if this stone really had the origin of the world, Gu Xuan would not have the desire to buy it at all.

Because although the stall owner didn't know the function of this stone, he marked it with a price of 1 million resource coins.

Obviously, this stall owner would rather kill the wrong person than let it go, and would rather rot on his hands than be picked up.

After walking around the stalls for a while, he didn't find anything, and Gu Xuan didn't care much, because the purpose of his trip was to go to the exchange hall to have a look, and the stalls outside the hall were originally attached.

It's good to be able to buy items that are useful to you, but it doesn't matter if you can't.

Compared to the bustling crowd in the booth area, when they came to the area of the exchange hall, the number of people immediately decreased sharply.

The circular exchange hall resembles the Colosseum in ancient Rome, with a total of 16 gates, and you can directly enter the exchange hall from where you are in the stall area.

After entering the slightly deserted exchange hall, according to the prompt information at the gate, Gu Xuan walked straight into the exchange hall, found a room that no one used, and pushed the door and walked in.

"Welcome to your visit, may I ask, what items do you want to exchange, I can help you directly filter and search, and reduce your search time."

After entering this exchange room, the inside is also like the outside stall, and the room that originally felt small was also a magnificent hall when entering it.

And in this palatial hall, Gu Xuan also unexpectedly saw a guy he had seen before.

Herus Wannian, the guy who looks like an octopus and has a little bad brain, just like a low-level NPC.

When Gu Xuan first came to Wanjie City, he was received by this guy as a newcomer receptionist.

It's just that this guy doesn't want to stay in Wanjie City as a novice receptionist, why did he come here to be a waiter.

The most important thing is that although this guy has changed positions, he still feels like a dull NPC to Gu Xuan.

"I'd like to find an item about the Source of the World!"

Items that contain the source of the world are of some help to the cultivation of the divine space, and if you can encounter the source of the world that matches your own divine space, then the improvement will be very considerable.

Therefore, items containing the source of the world are a very precious resource for beings above the 5th level god rank.

In addition, many big forces also need items and treasures that contain the source of the world to strengthen the small space in their own forces.

Originally, what Gu Xuan was worried about was to find and loot the items that contained the source of the world.

Will it arouse the suspicion of others that he has a new small world, in fact, it is completely unnecessary.

"At present, a total of 236 items that meet your requirements have been found, and 16 items about the origin of the world have also been found, do you want to continue to refine the filter?"

After hearing Gu Xuan's request, Wan Nian, who was wearing a delicate black suit and white shirt, blinked his eyes and waved his tentacles at Gu Xuan, revealing a light curtain that enveloped the entire room.

The 236 items he mentioned, which contained the origin of the world, and the 16 items that contained the origin of the world, were all displayed in front of Gu Xuan's eyes in the form of images.

…………

…………

As Gu Xuan reached out and touched the objects floating in the room, information about these items would be displayed aside.

Gu Xuan, who had nothing to do, directly rejected Wan Nian's suggestion to continue to subdivide and screen, and checked the information of these items one by one.

"Hello, help me get a world fruit."

After reviewing all these items, Gu Xuan almost understood the value of this item containing the power of the world.

Items containing less than 100 units of the Source of the World are basically 1 Source of the World, which can be exchanged for 1000 merit points.

And the higher the source of the world, the higher the merit value required for every 1 point of the source of the world.

As for the 16 additional World Origin items provided by Wan Nian, Gu Xuan said that what does that have to do with someone from him, does he look like someone who bought it?

Now, what Gu Xuan needs to figure out is how much progress this 1 unit of World Source has for the improvement of the Gu Nest.

Therefore, after checking them all, Gu Xuan said to Wan Nian the option he wanted to buy.

"Okay, a World Fruit is worth 13,000 merit points, you have a total of 81,200 merit points before purchasing, and you have 68,200 merit points left after purchasing."

Wan Nian, who had been waiting quietly on the side, waved his tentacle again after hearing Gu Xuan's purchase request.

As soon as Gu Xuan's words fell, an egg-sized, emitting pure purple light, like a purple jewel-like fruit, floated in front of Gu Xuan.

"Do you need to buy anything else?"

Just like an emotionless vending machine, after handing over the World Fruit to Gu Xuan, this Wan Nian continued to ask Gu Xuan.

I have to say that this Wan Nian seems to be more wooden and dull than when he received a novice.

"Thanks, not for now."

Gu Xuan, who is now buying a World Fruit, naturally needs to figure out how much progress this 1 unit of World Source is worth before he can decide whether to continue to exchange merit points for World Source after deciding whether to continue to exchange merit points for World Sources.

So, after casually thanking him, Gu Xuan left the room.

Leaving the room, Gu Xuan pretended to open the space stone on his body to hide people's eyes, but in fact, a small gap was opened, and the World Fruit was thrown into the Gu Nest.

And Gu Lele, who was in the Gu Nest, waited there early after getting Gu Xuan's information, and after Gu Xuan threw it into the World Fruit, he ate it in two bites.

"Obtain the Source of the World, increase the progress of the Gu Realm to 57.3%"

More than ten seconds after Gu Lele gnawed the World Fruit, Gu Xuan got a progress boost on the Gu Realm Ascension.

A World Fruit, containing 13 units of the Source of the World, increases the progress of the Gu Nest by 1.3%.

1 unit is 0.1% progress, and 1 unit is worth 1000 merit points.

According to Gu Xuan's remaining 68,200 merit points, he can also increase the progress of Gu Nest by another 6.8%.

Being able to obtain this amount of improvement was quite acceptable for Gu Xuan.

Of course, Gu Xuan didn't plan to use all the remaining merit points to exchange for items containing less than 100 units.

Although on the surface, the exchange contains less than 100 units, and the exchange ratio of Merit Points to the Source of the World is the highest.

However, no one in this world is stupid.

This arithmetic problem that elementary school students know, why does the City of Ten Thousand Worlds set a price that is obviously overflowing for those items that contain more of the source of the world?

And if his pricing can be accepted by the public, then it must be because he has such value!

Therefore, after Gu Xuan figured out the value of the world unit to him, he returned to the room just now.

"Welcome to your visit, may I ask, what items do you want to exchange, I can help you directly filter and search, and reduce your search time."

Seeing Gu Xuan come in, Herus Wannian once again greeted Gu Xuan mechanically, and then asked Gu Xuan as he did just now.

"I'm going to buy a Deep Sea Shenbo Skeleton, a branch of the World Tree!"

After already knowing that this Herus Wannian didn't have any wisdom, Gu Xuan didn't say anything more, and said straight to the point.

"Okay, a Deep Sea Shenbo Skeleton, worth 65,000 merit points, a branch of the World Tree, worth 3,000 merit points, you have a total of 68,200 merit points before purchasing, and you have 200 merit points left after purchase."

Although this Herus Wannian has no wisdom, his movements are unusually sharp.

Almost the next second after Gu Xuan finished speaking, this guy had already sent an amber gem that stored the bones of the Deep Sea Divine Bo, as well as a branch that was only more than twenty centimeters long and exuded a rich breath of life, to Gu Xuan's body.

"Thank you and goodbye!"

Anyway, this Herus Wan Nian didn't look like he was wise, so Gu Xuan didn't bother to avoid him, and habitually opened the space stone, and then threw the amber gem that stored the bones of the deep sea god Bo, as well as the branches of the World Tree, into the Gu nest.

And Gu Lele, who was waiting in the Gu Nest, quickly took over the two items.

After unsealing the bones of the Deep Sea Divine Bo, he was sent to the Lake of the Divine Domain, and the branches of the World Tree were fused into one of the roots of the Gu Tree by Gu Lele.

"Obtained Deep Sea Shenbo Bones (Revived), Gu Realm progress increased to 66%"

"Obtaining the World Tree Branch, the Gu Tree has been improved to a certain extent, and the progress of the Gu Realm has been increased to 70%"

The reason why Gu Xuan chose these two items was that one was to consider the number of his merit points, and the other was to consider that these two things were more compatible with the Sea of the Divine Domain and the Gu Tree in the Gu Nest.

Perhaps, just like in the space of the gods, if you get the source of the world that matches your attributes, you can get more improvements.

It was for this second reason that Gu Xuan finally chose to exchange these two items.

And when Gu Lele placed these two items, it was indeed as Gu Xuan guessed, he had gained a certain amount of additional improvement, directly increasing the Gu Realm to 70% of the progress!
