Hyperdimensional Harem Exploration Project

Chapter 6 Return to Terra

The environment of the sandbox world is currently considered safe and stable, and it is a good place to retire to the countryside. However, it is not without its shortcomings. Due to the lack of development time, it is still relatively backward, and many places are not modern, especially in the medical field.

And this is the problem. Currently, all the Sarkaz he recruited are patients with Originium disease. Originium disease is to some extent similar to AIDS, an incurable disease that turns people into medicine jars that require long-term treatment to maintain health.

As for things like Originium disease inhibitors, there is no comprehensive medical system, but he doesn't have any.

Xu Ya knew very well that he had to return to Terra, back to that terrible world.

If I could, I definitely wouldn't want to go to Terra. After all, it's a super dangerous place based on its setting.

The background information shows that more than 10,000 years ago, the continent of Terra was visited by a prehistoric human civilization. This interstellar force represented by the Doctor, which had at least a third-level civilization strength, was forced into the brink of civilization extinction by some unknown "ultimate darkness", so they had to stay in Terra and research various means to preserve the spark of civilization.

The Deep Blue Tree of the planetary transformation device, the Heavenly Fulcrum of the military command system, the Preservation Project that freezes the survivors of the former civilization, the Polar Star Gate for teleportation, and the most important Originium Project are all the last means left to revive civilization after surviving the "Ultimate Darkness".

However, the ultimate darkness has not yet arrived, and the fire project launched by this extinct interstellar civilization has either failed or become an imminent new threat.

In addition to the Heaven Fulcrum where God cosplays to build Lateran, and the survivors who are currently surviving in Columbia, the Terra continent is now facing the following world-destroying crises: the Deep Blue Tree that was turned into a sea heir by the Agors is wreaking havoc on the world, the Polar Star Gate connects to the subspace and causes the problem of evil spirits, and finally the Originium left over from the previous civilization. The early Originium combined with the local small animals of Terra, and through some influence, created the Terrans one by one, creating the current Terra civilization. However, the Originium has now become a major concern, and is constantly spreading and covering the earth, threatening the entire Terra civilization.

Each crisis alone is world-destroying, but all of them are gathered together on the magical Terra.

Xu Ya asked himself that he was just a little Karami, and it was unlikely that a human who did not even meet the standards of a Level 1 civilization would be able to solve these complex problems.

If he has the Star System, then there is nothing to say, just take it head on.

It’s a pity that what he has in his hand is a farming-related cheat code, and a system with an incomplete technology tree, so it’s better to seek benefits and avoid harm.

What's more, his roots are in the box world.

It's not that Terrans don't care about Terra's affairs. Xu Ya's goal was simple - he chose to save his friends and those who were willing to follow him.

"Mud Rock, I think we need to go back to Terra to collect some medical equipment and Originium disease inhibitors. I want to study Originium if possible."

Finally, the Sarkaz's condition was barely stabilized with the help of the warlocks' somewhat crude medical skills, but it was unclear when the next attack would occur. Time is precious, so Xu Ya made a bold proposal to Mudstone.

The Sarkaz are an excellent workforce in all aspects and are high-quality immigrants.

Xu Ya was unwilling to sit idly by and watch the death of his people, who to some extent belonged to him. At least in the box world that he controlled, tragedy should not happen!

"Do you really want to go back?"

At this time, the Sarkaz were the ones who were unwilling to leave. A harsh government is more ferocious than a tiger. When they thought about going back to Ursus, that torturous place, they would rather die in the box garden world.

"Don't be so shy, we're just going to be there for a while. You can see how backward the technology here is. We need to introduce some technology and equipment to improve our living standards. We can also help you suppress the Originium disease. Anyway, you can come back here anytime, so don't be so reluctant, okay?"

Looking at the Sarkaz who were unwilling to go back to the box garden even if they would rather die, Xu Ya couldn't help but shook his head and said to comfort them.

hum-

The power from higher dimensions tore through the space, and the space-time channel burst open.

Xu Ya and the fully armed Mudstone came out.

At the back, a dozen or so of the most elite Sarkaz from the Mudrock Squad treated themselves like oxen and horses, pulling carts of food, with barrels of wine following closely behind, and they also set foot on the icy and snowy land of Ursus again.

"Ah, I'm finally back. This white scenery and low temperature... I really can't like it."

The Sarkaz looked at the cave which had not changed much from when they left and sighed that Ursus was not a good place and they did not like Ursus either.

As for Mudstone, he was silent as a mute person and said nothing. He just stood firmly beside Xu Ya to protect the latter.

More than a month of getting along also made her realize how fragile this human who did not look like a Terran was.

"It's so cold...it's snowing again."

As expected, even though he was wearing the thickest clothes and wrapped himself up, Xu Ya was still instantly numbed by the biting cold wind of Ursus. As a southerner who has lived in the subtropical zone for many years, he has no resistance to freezing at all.

"Doctor, I've already told you that you're weak and shouldn't have come here. Just let us do our work."

As for the Sarkaz around... they gave their warmest clothes to Xu Ya, their benefactor, and smiled kindly. These tough guys were only wearing the thinnest clothes, and the cold only made them feel a little uncomfortable... The Terran people's body system was indeed a little abnormal.

It is no wonder that the Sarkaz unanimously opposed Xu Ya's idea of ​​emulating a doctor from a previous civilization and following him to tour the Terra continent and monitor the customs and habits of different civilizations.

He is too fragile.

"Okay, enough of the nonsense. Let's go to the village first. I need to repay the favor first."

Xu Ya suddenly remembered that he had deceived the Ursus villagers and that he still owed them a promise. If he had not returned to Terra, he would have almost forgotten it. Now that he remembered it, he had to fulfill his promise.

It didn't take them long to reach the village gate.

The village chief greeted them, and seeing the bags of food and grain wine that Sarkaz had thrown on the ground, the villagers' disgust for the infected people became much better. If they ate these foods sparingly, they would be able to live a good life for a few years.

Now we are even.

Afterwards, in order to rush to treat patients whose Originium disease had entered an unstable stage, everyone began to march southward despite the strong wind and snow.

As for the destination, they had already chosen it. Ursus could not stay there for a moment, and the nearest countries were only Leitania and Da Yan. As a Chinese, Xu Ya wanted to choose Da Yan, but when he learned that the familiar Chernobog and Longmen did not exist, he was immediately numb.

Obviously it was too early, and the continent of Terra was not yet what he was familiar with.

In the end, he had no choice but to go to Leitania, a place that the Sarkaz were more familiar with.

Today, Lethania is under the rule of the Witch King, whose reputation as a wise king is even known to the Sarkaz of Ursus. From this, we can infer that the Witch King may have just ascended to the throne for a few years, and he is not yet completely crazy, and the social environment can be said to be quite good.

In addition, Fremont, the lord of the Lich King's Court of the Sarkaz, became the teacher and advisor of the Witch King at this time, and naturally he also took some care of his fellow countryman.

With someone to protect them, the treatment of Sarkaz in Leithania can be said to be one of the best in Terra. No wonder it attracted many Sarkaz to settle here.

Once the goal is determined, start moving forward.

The well-fed Sarkaz said that traveling 800 miles a day was not a problem at all. If there was no natural disaster and the journey was smooth, it would only take one or two days to reach Leithania.

However, Xu Ya is not Terra Superman, and he once again tragically discovered that he is a complete weakling who cannot even keep up with the team.

But some kind of stubborn self-esteem made him unwilling to show his weakness, and he insisted on walking on his own. In the end, it was the Sarkaz beside him who supported him, and Mudstone personally held his hand and pulled and pushed him forward, accommodating him to walk. After walking for more than half an hour in the wind and snow, his limbs felt heavy and uncomfortable as if they were filled with lead, and fatigue had already surged into his heart.

"Don't push yourself anymore, just take a good rest."

Finally, he had no choice but to accept Mudstone's "persuasion" and was easily picked up by the Sarkaz girl and placed on the truck. She then considerately set up a small tent to shelter him from the wind and rain.

Next time, I must practice well to avoid making a fool of myself again.

Due to fatigue and cold, Xu Ya, whose consciousness was a little fuzzy, gradually fell asleep.

When he woke up again, he opened the tent and looked out, only to find that the wind and snow had stopped and it was bustling outside.

"You're awake, are you feeling better?"

Sarkaz, who was in charge of looking after Xu Ya, immediately notified Mudstone to come over when he saw the former get off the truck. Wearing heavy armor, she ignored the merchants who were still negotiating and walked back to show concern.

"I'm much better. How long have I slept? Where am I now?"

"It's been almost a day. We just entered the wilderness at the border of Ursus and we happened to run into a caravan. Let's trade some more goods according to your wishes. Xuya, do you have anything you want to buy?"

Mudstone briefly reported their itinerary. The Sarkaz, who were not at the bottom of the list, walked very fast. Their strong physique allowed them to travel all day without sleeping, and they were eager to leave Ursus.

After entering the wilderness buffer zone between the two countries, the Mudstone Team encountered caravan merchants that are quite common in the wilderness.

The two sides had a friendly contact, so they took out their surplus materials for trade during the break. Mudstone also followed Xu Ya's plan and traded with other Terrans using the abundant grain grass, grain wine and cooking oil produced in the box garden world as their main products in exchange for materials they could not produce, especially medical supplies related to Originium disease.

At present, the caravans were not very interested in grain grass, which took up a lot of space, was large in weight but had low value, and only bought a small portion for the sake of novelty. However, they were very interested in grain wine and cooking oil. The wine and cooking oil produced by the standardization of the box garden world were of high purity and had no extra impurities.

The quality alone was enough to make the savvy merchants buy all the wine and oil products after tasting them, and the Sarkaz also received a considerable amount of compensation for the first time.

........

Xu Ya took the source stone ingot given by Mudstone and walked in front of the vendors' stalls to see if there were any good things worth noting.

Longmen does not exist at present, so there is naturally no talk of Longmen coin as an international currency.

Therefore, there are many kinds of currencies, from crudely cast bars of red gold, exquisite gold coins privately minted by nobles from all over the country, to Originium, Originium ingots, and Originium processed products. As long as their value is recognized, they can be used as hard currency.

However, people living in the wilderness prefer Originium currency that can be used as energy.

"Sir, is there anything you're interested in? We have a lot of good stuff here!"

A female businessman with antlers who could be identified as an Elafian race came forward to ask Xu Ya enthusiastically with shining eyes when she saw him not hiding his wealth.

If it weren't for the Sarkaz mercenaries guarding Xu Ya like guardians, the dusty Elafia would have come over and used the unique advantages of females to seduce this man of unknown race to make impulse purchases. She could see that the man in front of her was the leader of this Sarkaz mercenary team, and he must be a big money sponsor.

"Can you tell me what you have?" Xu Ya looked at the girl with deer horns with shining eyes. Having seen many girls with white hair and red eyes, he was not tempted by her beauty but asked calmly.

When the Elafia merchant heard that there was something interesting going on, she began to describe the goods in her hands as if she were reading a menu.

Wine and Originium products from Gaul, sabers and armor from Ursus, musical instruments and delicacies from Leithania, gems and folk art from Victoria. It seems that this caravan has visited many places and accumulated a lot of good things.

However, Xu Ya didn't seem to be interested, so he asked, "Do you have any books on Originium skills? Or Leitania's staff or spellcasting units? I'm more interested in these."

"Oh, I didn't expect the guest to be a sorcerer. Of course I have these. But... you know."

The Elafian business woman made an internationally accepted gesture, indicating that more money was needed. These things were obviously too precious to be displayed casually at a roadside stall.

"can."

Xu Ya casually threw the Originium ingot in his hand to the business woman as a deposit. The latter also diligently took out the books she had carefully collected and the worn-out spell unit she had "picked up" from Leitania.

Just when Xu Ya encountered these things, the system suddenly issued a prompt.

[If an unknown item (technology) is discovered, should it be digitized? ]

Chapter 7: Originium Technology Tree

Confirm the digitization.

[The spellcasting unit has been analyzed, the Originium skill 'Black Mist' has been recorded, and the 'Originium' technology tree has unlocked the 'Spellcasting Unit' construction list. ]

[The elementary Originium skills summary book has been parsed, unlocking the Originium skills learning interface. ]

The goods that the Elafia merchant gave him were genuine, but he didn't understand the English-like words on the books. Fortunately, he got an unexpected reward.

Xu Ya opened his eyes and happily discovered good news.

Do you remember the 'Originium' technology tree that was unlocked after he signed various agreements with the ignorant little girl Meli when he first explored the Terra continent through the dimensional star map?

Currently, there is a blank in this technology tree. There are two ways to fill this blank.

The first is to absorb Terra's existing technology, digitize it, and store it in the system database as part of his technology tree.

Another way is to recruit Originium scientists to specialize in researching new Originium-derived technologies and unlock the technology tree.

The equipment created by these digital technologies can ignore the original restrictions! For example, if the magic unit originally used by warlocks is created through the system, then even Xu Ya, a pure human who should not be adaptable to Originium skills, can use "magic".

In addition, the newly emerged Originium skill learning interface allows him to directly learn Originium skills and accumulate experience points through reading, training, and performance, thereby increasing the so-called Originium skill adaptability.

In that case, the plan will have to be changed.

While saving people, I also collected books and Originium devices to feed the system to see if I could strengthen my own strength.

Xu Yatai longed for power, especially after a group of Sarkaz appeared around him. Each Sarkaz had his own strengths, each had his own unique skills, and their fighting spirit and endurance were amazing, making them unattainable for the humans on Blue Star.

Now that there is a new dawn, how can we not seize the future!

Thinking of the future, when he would become the invincible God of Magnetic Field, Xu Ya couldn't help laughing. He only stopped laughing when the people around him looked at him strangely. Then he took out more Originium ingots. "Your stuff is good. I am very satisfied. I wonder if there are more spellcasting units and skill books with well-preserved cores."

"These are the best I can offer. If you really want them, you may have to go to the mobile city to see them. Is there anything else you need?"

The merchant Elafia was very happy to receive the payment, but she regretted having to give up the next transaction and explained her difficulties.

Because she didn't prepare much of these goods, people in the wilderness rarely read books, and spellcasting units are extremely precious.

It was said that this staff-shaped spell-casting unit was left behind by a fallen noble, so she collected it.

"Okay then." It's a good opportunity to find a bargain once in a while, so Xu Ya didn't force it. He continued to pick and choose from the goods displayed by Elafia, and actually found some good things.
