A sand ostrich dragon skin, in exchange for a "sand vulture cup" source of life;

Ten sand loquin skins for a "sand vulture cup" source of life;

A crocodile skin bone wolf skin, for ten "sand vulture cups" source of life;

all kinds of ores, one kilogram of "sand vulture cup";

......

The "Sand Vulture Cup" is the kind of bird skull spoon used by the Sand Barbarian Elders in the ceremony to distribute the source of life.

One scoop of about 10 ml of liquid is equivalent to the daily quota of a high-level Sand Barbarian Warrior.

As for all kinds of animal bones, they were simply packaged to Bai Yuqi at the price of one hundred kilograms of a sand vulture cup, regardless of type.

This price makes both parties feel guilty.

The sand barbarians were weak because they felt that they had sold their household garbage to the most expensive guests of the Rift Valley tribe at the price of gold.

And Bai Yuqi's lack of heart is these animal skins and bones, which are precious arcane materials that he can't get in the Tang Dynasty time and space, but he used seawater ice as money to exchange them back.

In order to purchase all kinds of arcane materials in the hands of the sand barbarian spirits, Bai Yuqi had already divided the white vortex incarnation on the way to the Great Rift Valley tribe and asked him to return to Chechnya Island to prepare, and cut the seawater ice of the Caspian Sea into a standard cube of ice, ready to be used to pay for the purchase.

However, after discovering that the sand barbarians measured the source of life in units of 10 milliliters, they asked the white vortex to incarnate and cut a cubic meter of sea ice into 100,000 small square ice, and stored it in a dimensional bag, ready to be used as currency.

But now that he's bought a bunch of arcane materials, he hasn't been able to use up a single cubic meter of sea ice.

Under this kind of transaction, where both sides touched their own painful consciences, Bai Yuqi almost wiped out the entire Great Rift Valley tribe.

All the sand barbarians held a clay pot used to hold the source of life, and looked at the cave on the four walls of their house in a daze.

Therefore, impulse consumption is not advisable.

When the sand barbarians found out that the things they thought were useless at home could be exchanged for the source of life.

In a moment of excitement, even the animal skin clothes on his body were taken off and replaced with the "Crystal of Life" in Bai Yuqi's hand, and when he came back to his senses, the old and young masters of the entire tribe were all shirtless and looked at each other.

Out of "guilt", in addition to the hundreds of tons of seawater ice used to purchase materials, Bai Yuqi also gave an additional ten tons of seawater ice to the Great Rift Valley tribe for free as an advance payment for the long-term purchase of various materials, which made the Sand Barbarian Elders and the leader Quirion look at him with little stars in their eyes.

At the same time, at the price of 10 "Life Crystals" per day, a large number of sand barbarian spirits from the Great Rift Valley tribe were hired to work for themselves, preparing to establish a permanent camp near the plane passage on the Ash Wasteland as the Datang Time and Space Office in the Havoc Plane.

This news once again caused a sensation in the Great Rift Valley tribe, as long as it was a movable sand barbarian spirit who rushed to sign up, the sand barbarian elf elder and the leader Quirion saw that there was almost nothing but stones and sand, and the tribe simply decided that the whole clan poured out of the nest to work for the big white boss!

For a time, the great migration of tens of thousands of people from the sand barbarians almost alarmed the entire ash wasteland, and I thought that the sand barbarians were ready to attack that tribe.

And when Bai Yuqi returned to the vicinity of the plane passage with tens of thousands of sand barbarian spirits, they were taken aback again.

Because on the original barren wasteland, I don't know when a towering city has been erected, which happens to surround the strange light source in it.

At the same time, thousands of tall human warriors, and countless golden iron men, were busy building cities in the wasteland.

Bai Yuqi sent the white vortex incarnation back to the Tang Dynasty time and space, but it wasn't just for him to go back and cut the ice.

Although the human warriors of the Datang time and space could not adapt to the environment of the cataclysm plane, the regenerated Heroic Spirit Legion, which was essentially an undead, was not afraid of the heat of the Ash Wasteland.

In addition to the hundreds of thousands of regenerated heroic spirits under the command of Gu Aotian, the three major divisions of the brain beast, "Scarlet King Kong, Blood Armor Tyrant, and Bloody Tai Sui", also brought hundreds of thousands of blood ape clones of his subordinates.

Bai Yuqi directly mobilized 100,000 junior construction and intelligent machinery workers from Yingzhou to prepare to build a large base on the wasteland.

The sand barbarians who had been confident because of the hundreds of Eternal Fire warriors in the tribe and thought that the Great Rift Valley tribe would become the leading force in the Ash Wasteland were stunned by this huge scene.

The original majestic momentum suddenly wilted, and he followed behind Bai Yuqi with fear like an old peasant in the countryside who had just entered the city, and entered the city that had just been named "Ash City" by Bai Yuqi.

They can't help it, among those reborn heroic spirits with human appearances, there are as many as 100,000 white bone heroic spirits at the junior warrior level alone, as many as 10,000 black bone heroic spirits at the intermediate warrior level, 1,000 undead lieutenants at the senior warrior level, and even hundreds of undead generals at the "Dark Fire Warrior" level.

Although their Great Rift Valley tribe has a population of tens of thousands, there are only more than 100 leaders of high-level warriors, even if you add more than 1,000 middle-level warriors and adult clansmen equivalent to junior warriors, it is only a few thousand troops, and the rest are old and weak women and children who have no combat effectiveness, which is different from the militarized forces where all of them are warriors.

Coupled with the hundreds of thousands of blood-red orcs, the sand barbarians couldn't imagine that there was such a force in the Ash Wasteland that could have such a powerful force, even the Oasis tribe, which claimed to have a population of one million, could not do it like them.

Bai Yuqi didn't bother to comfort the shocked hearts of the sand barbarian spirits, and after settling them down in the city of ashes, he took the time to inspect the construction situation.

Because the ash wasteland is basically a Gobi made of gravel and rubble, and the land is so barren that even grass cannot grow, so the buildings in the city are basically semi-underground buildings.

Due to the energy turbulence area near the plane passage, it is not possible to use construction spells such as [Fossil to Mud], [Mud to Stone], and [Soil Removal] nearby, so in order to protect the plane passage, manual work can only be used.

A large number of large-scale engineering golems are excavated from the gravel and then transported to the edge of the energy turbulence area with transport golems, where they are plasticized and processed into modular building materials, and then transported back and assembled like stacked blocks.

The main body of the building is located underground, so the surface of the ground is basically a closed roof structure, which is used to shield the dark sun and remnant sun radiation in the sky of the Havoc plane.

The interior of this "semi-underground city" is transplanted with a large number of potted plants to form greenery to improve the extremely dry air of the Havoc Plane.

At the same time, large chunks of seawater ice are cut and transported through plane passages to cool the stuffy underground space, and the melted ice water flows into the underground reservoir for storage, and the volatile part is considered to humidify the internal air.
