The development of world civilization has gone through many eras, from the earliest prehistoric era to the steam age to the information age, and now it is the age of vitality!

Just as the ancients would treat steel machinery as monsters and couldn't understand what the 'brain of electricity' was, modern people may not be able to understand the vitality of civilization.

The tribal architecture of this era does not need traditional construction methods, but is divided into three parts: core, keel, and empty building stone.

Placing a Core in the Juggernaut and praying for a sacrifice will spawn a Metaverse aggregate known as Slave Labor.

Keels are a general term for certain materials that were used by slave laborers to build the main structure of a building, to which were then attached to the empty stones.

This kind of stone is like coral stone, it will absorb the elements in nature and grow on its own, so it is very convenient to build a building in the Genki era.

"What level of core is this?"

In the tribal era, the building had different grades, the higher the level, the more powerful and rich its function was, Xia Ye looked at the stone slab, and looked forward to it: "This is a relic that my father carefully treasured, it should be very powerful, right?"

"I don't know!"

Xia Lingyue shook her head: "But it seems that you can summon heroes!"

The function of the Hero Altar is to provide a place for the heroes of the tribe to rest, practice, and compete, to put it bluntly, it is to keep the heroes in the best condition!

"What?"

Xia Ye was stunned for a moment, he had heard that a few powerful tribes had rare hero altars, and after offering sacrifices, they could summon heroes who did not belong to this era.

"Could it be that I can still summon Daji or the big-breasted Black Joan of Arc? Let them warm the bed? No, let them follow me in the four directions?"

"What did you say?"

Xia Lingyue didn't hear clearly.

"I said I'd be a great hero!"

Xia Ye wiped the cold sweat on his head, and almost said that he had leaked his mouth.

"You're not only going to be a hero, you're going to be a wise tribal chief, okay, put your things away and take them with you when you're in the Blood Survival Trial!"

told her brother the secret, and Xia Lingyue was relieved.

"Sister!"

In fact, Xia Ye also has a secret, he is a 21st century college student, one Friday during the winter vacation, he was taking advantage of the off-season to travel in the Zhangjiajie Nature Reserve, and suddenly received a text message.

"The world is going to be destroyed, run, go to a place with lush plants and hot springs!"

Natsuno thought it was a prank, but two hours later, the mysterious spore virus began to spread wildly.

No one is immune, and Natsuno still clearly remembers the pain of being spored when the spores parasitize his body and take root and sprout.

The last time he saw the world, many tourists screamed in horror and fell into the stream, covered in plant fibrosis.

Then, hundreds of millions of years have passed, and the vicissitudes of life!

Xia Ye seemed to have returned to the fetal period, and his consciousness was blurred, until one day, a thunderclap woke him up from a long period of slumber.

The raindrops the size of broad beans slapped on his body, watering Xia Ye through.

This is a spring stream in the forest wasteland, not far from the summer field, is a towering ancient tree that has grown for an unknown number of years, the branches and leaves are luxuriant like a giant umbrella, but now it has been split by thunder, and the raging flames are burning, even heavy rain can not extinguish it.

Natsuno fell into the creek, and just as he was about to drown, a thick arm scooped him up.

Maybe it's because the nutrients are drained by mysterious spores, maybe it's the impact of hundreds of millions of years on the body, or maybe it's the nourishment of vitality, anyway, Xia Ye's body has returned to the size of five years old.

While learning about this world, Natsuno's memory began to slowly recover, and he felt that he was lucky.

So many tourists dropped the stream and turned into plants, and after that, the landscape changed, but this part of the summer field was nourished by spring water and grew.

In the end, if he hadn't been struck by thunder, Xia Ye would have either become a part of the ancient tree or suffocated inside.

Xia Wuyan was a homeless person back then, and he was fighting in this ancient forest, if Xia Ye hadn't been found by him who went to fetch water, he would have died.

You must know that in this era of food scarcity, many people will abandon their newborns, and even eat their children, Xia Wuyan can raise Xia Ye without hesitation, this kindness is enough for him to fulfill the last wish of this 'father'!

"What?"

Summer moon in the clay pot rabbit meat to avoid mush.

"I'm going to go to the Fengjing Ruins!"

Xia Ye thought about it carefully, but he still didn't plan to tell his sister this secret, not because he couldn't trust her, but because he was worried that it would bring her danger.

"I heard that Xia Frog is also going, do you want to be together?

The summer moon is not unexpected.

This ruin, once the main city of the once-powerful Toyokyo tribe, has been explored many times by the heroes of several nearby tribes, but for young people, it is still as alluring as a smash hit Oiran.

In addition to accumulating some experience, maybe if you are lucky, you will pick up one or two treasures, you must know that such a large relic as Fengjing, with the erosion of the years, will continue to weathered and dilapidated, and it is likely that the treasures buried before will be exposed.

"I'm Banxia!"

Xia Ye laughed at himself, because he always wore an eye patch in his left eye, the people in the slums called him Banxia, which means half-blind, plus he was sick in bed all the year round, so people would not team up with a 'weak chicken' like him!

"Hmph, my brother is the best!"

Xia Lingyue pursed her lips, followed by a trot behind the door, and dug out a small cloth bag from the ground: "This is what I have saved in the past three years, you can use it to buy some equipment!"

Xia Ye's eyes were wet, and he wiped them quickly so that the tears didn't flow.

In the cloth bag, there are thirty-seven knife coins,

In this era, ordinary people are still in the stage of bartering, and knife coins are only circulated in a small area, but because they are made of bronze, they are definitely hard currency.

A knife coin can buy ten stone of grain, and stone is the unit of weight in this era, that is, one catty, so the private money in Xia Lingyue can be said to be a huge amount of money.

"Fool, it's all because of your wisdom that I can save this money!"

Xia Lingyue reached out and rubbed her brother's hair.

Other families, even if they have strong labor and work hard, they are just filling their stomachs, but their own family is different, my younger brother has dared to go out of the city alone since he was a child, and he can always bring back some things that others don't know.

Xia Ye shook his head, he liked to read books since he was a child, not to mention living in an era of knowledge explosion, he could become a learned person by touching the screen with his fingers.

Due to the destruction of the world and the rupture of civilization, those common sense in the past have long been drowned in the long river of years, and others dare not touch crabs and sea urchins when they see them, and they don't know how to eat them.

Relying on the rich knowledge of survival in the wild, although there is no need to worry about starvation, it is absolutely impossible to save so much money, so Xia Ye will never forget the back of his sister sitting in the yard and polishing the arrow cluster by the moonlight.

You must know that with a skilled worker like my sister, it takes more than a month to polish a thousand arrow clusters, and these can only be exchanged for one knife coin!

"But it's not enough, a tribe needs five basic buildings, we only have the Ancestor Altar and the Hero Altar, and the rest of the Juggernaut Tower, Spring Water Tower, and Yuanqi Tower are all gone!"

The summer meniscus calculates on your fingers how much it costs to buy.

"Don't bother, I can go and grab it, and fight to feed the war!"

Natsuno comforted.

As long as you defeat other people's tribes and dismantle the tower, you can move resources such as cores and keels back for your own use.

"What nonsense?"

Xia Lingyue rolled her eyes: "Don't talk about heroes, you don't even have small soldiers, what can you do to demolish other people's towers?" I'm afraid you can't even climb over the fence, right?"

"The boat will naturally go straight to the bridge, maybe I will find a few small soldiers in the Fengjing Ruins!"

Xia Ye is not panicking, in this era, there is a kind of naturally existing 'building' that can give birth to soldiers, for example, in some places where strong winds often blow, there will be wind caves, which can give birth to wind soldiers.

Catch a Tempest Soldier and make a lot of money, if you can transfer the Wind Cave to the tribe, it will be a big profit, because in time, you will get a Tempest Troop.

The molten soldiers of the Xia tribe, even in the Zhao Kingdom, are ranked highest, and they have always been coveted by the patriarchs of various tribes.

"I still have to make money!"

Xia Lingyue sighed, her eyes fell on the charcoal, and she shook her head, no, there is no technical content, and there is no means of secrecy, and it may be imitated if it is not sold for a few days.

Besides, even if they hoard a large number of them and sell them together, this is not a necessary material for life, and let the poor spend money on this, they probably would rather go into the mountains to cut firewood themselves.

The first thing they thought about must have been how to find out how to burn charcoal!

"It's not okay to sell charcoal, don't forget, the nearby mountains and forests are all Xia patriarchs, everyone chops some firewood, boils water and cooks no problem, but large-scale felling, then wait to be captured by the Xia family and hanged on the execution ground!"

Xia Ye couldn't help but tease when he saw his sister's gaze.

"In fact, even if I can do it, I won't do it, the charcoal production rate is too low, and I can't make a few dollars after working hard for a day!"

Xiangshan monk Bai Juyi's "Charcoal Seller" is a must-read in middle school textbooks, and Xia Ye doesn't want to be a miserable charcoal seller.

"Then sell salt!"

Xia Lingyue gritted her teeth, and her eyes fell on a piece of smoked ham hanging in the corner of the room.

Salt is a necessity of life, so it has always been very expensive, but my family has never bought a grain of salt, because my younger brother can bring back a bamboo tube of salt every time he goes to the wild.

Xia Lingyue couldn't help but be curious and followed to see it.

It was an abandoned salt farm, known to many people, but no one ever ate it, because the salt lumps that fell from the walls of the salt cave were so bitter that they would kill if they ate too much.

The younger brother made a bamboo tube, stuffed some charcoal, tied a few layers of linen, threw the salt lumps in the water, removed the debris, and then poured them into the bamboo tube.

He said that this is called filtration, and after seven or eight times of the same step, the resulting water is boiled in a stone pot, leaving behind a layer of particles.

Smooth, fine, with a twist of your fingers, the touch is simply an intoxicating pleasure, and after tasting it in the summer month, you can no longer eat the salt from the market.

"Don't you think we're dying fast enough?"

Xia Ye played with the bronze sword, in any era, salt and iron are strategic materials, the state monopoly, and the money bags of those in power, ordinary people touch it, and there is absolutely no place to bury them.

"Sell less, then?"

Xia Lingyue sighed, her eyes looked at the smoked ham hanging in the corner of the room, she also knew that the Xia tribe had fought with the Cao clan for hundreds of years for a salt farm, and many people died before they were occupied, and now they still send heavy troops to guard against salt stealers.

To make smoked ham, in order not to let the meat rot, a lot of salt is needed, even the nobles are reluctant to do it, but they can hang two thick wild boar hind legs every winter.

The salt consumed alone is worth thousands of dollars, and of course, the huge cost of buying salt can be regarded as a large savings.

"Don't worry, I'm ready!"

Xia Ye smiled mysteriously: "Eat first!"

In this world, before there was no power to protect himself, Xia Ye had been carefully hiding himself, as long as he could eat enough, he didn't want to enjoy it, and now, when the time came, he was going to start his revenge plan, the blood was sacrificed, and the death of his father, these two accounts must be calculated with the Xia family and King Zhao!
