My Post-Apocalyptic Territory

The demonic tide came and went in a hurry, like a responsible deliveryman, leaving behind love and warmth here.

Fortunately, as a universal currency of the new century, the Source Crystal's strength exceeded Tang Yu's expectations. Despite the endless destruction caused by cannons and arrow towers, the Source Crystals were still intact. In fact, because the corpses of these demonized beasts were either destroyed or broken, the Source Crystals were quite easy to collect.

It wouldn't be bad if it were like this again... what a load of rubbish!

He still felt bad about the materials. These things could not only be used to make equipment, but more importantly, he was going to Lin Dong soon. Lin Dong was such a big shelter, there must be a market there, right? Tang Yu was still looking forward to making a fortune.

In addition, there were some powerful demonized beasts whose materials were relatively well preserved. Tang Yu ordered his men to collect these materials while he tallied up the profits from this battle.

The mutated beast brought so many source crystals, so this was definitely a profitable venture. However, this wave of losses was not without its challenges.

Just constructing these defensive structures, not even considering the materials, cost two thousand Source Crystals. Furthermore, these defensive structures also consume energy when they attack.

Where does this energy come from? It comes from Source Crystals, of course. Tang Yu stored some Source Crystals in the castle's small warehouse, which were used for the defensive buildings. Otherwise, he wouldn't have waited until now to build the defensive buildings.

Tang Yu remembered that there was a building in the level 3 territory called the Energy Well, which could absorb free source energy in the air to replenish the energy of defensive buildings. Before this building was built, these defensive buildings were probably huge consumers of crystals.

Tang Yu was in a good mood because he had made money. In addition to the previous plunder at the source crystal mine, he already had a lot of source crystals. Before going to Lin Dong, he would definitely spend these source crystals in the most appropriate way.

The other survivors were also very happy.

This is a case of surviving a disaster.

The city gates have reopened, and some of the braver survivors have stepped forward to examine the mutated beast corpses up close.

"My God, it's huge! Even such a massive demonic beast is dead!"

Ordinary survivors had never been in close contact with mutated beasts before, so one survivor poked it and found that it was indeed quite hard.

So many terrifying demonic beasts attacked, but the sanctuary successfully dealt with them.

A shelter for fewer than 100 people.

Such a record, who would believe it if it were told? Although most of it was due to Director Tang's efforts, that doesn't stop them from having something to brag about!

In the past, many ordinary survivors could only eat and wait to die every day, but now it's different. As long as they work hard, they can eat well every day. Now they also know the power of the shelter. Even the demonic tide can't do anything about it. In the apocalypse, is there a safer place than a large shelter?

Unbeknownst to them, the survivors developed a sense of belonging to the shelter and felt genuinely fortunate to have come here.

…………

After the demonic tide ended, Tang Yu didn't rest. He left the outside affairs to Chen Haiping and Luo Zhe, while he went alone to the back of the castle, the area used to build system buildings.

Of the four core components, the tavern, workshop, and market have all been built, leaving only the research institute.

Tang Yu had No. 1 and No. 2 transport materials back and forth, and finally saw on the panel that the construction conditions were met.

"Building a research institute consumes 1,000 units of source crystals, 100 units of wood, 300 units of stone, and 300 units of iron."

As before, a three-story building soon appeared before Tang Yu's eyes.

Step inside.

The research institute was filled with all sorts of research equipment. Tang Yu looked around and recognized very few of them, except for a beaker, the kind he had used in high school experiments. He vaguely remembered it... or maybe it just looked similar, but anyway, it was a beaker.

None of these are important; what is important is the function of the research institute.

As an important functional building, the research institute holds an indispensable position.

Research and development blueprints, reinforcement blueprints, modification blueprints, etc. are all functions of the research institute. In theory, as long as there is enough knowledge and source crystals, the research institute can develop the desired blueprints on its own.

That's a long way off.

Currently, the research institute is at a low level, and Tang Yu is not prepared to invest too many source crystals; he mainly uses its function of modifying blueprints.

For example, the workshop only provides one type of blueprint for basic longswords, which is very inconvenient. What if someone wants to use a knife or some other weapon?

Modification blueprints can transform longsword blueprints into battle blade blueprints. Of course, the level remains the same, and it is still a basic rune-equipped item, but it has more versatility.

Moreover, the basic material used for longsword blueprints is iron. After the blueprints are modified, materials from mutated beasts can be added, such as mutated beast claws and bones. Although the blueprint level remains the same, the materials used are better, and the resulting weapon is naturally more effective.

Tang Yu first modified the blueprints for the battle sword, and then designed a blank shield blueprint without runes and a blueprint for firearm bullets. With the blueprints, they could be mass-produced in the workshop.

After finishing the research institute, he didn't continue building anything and instead went to the market.

He didn't choose to build any more system buildings, not because he didn't need them, but because... they were unnecessary.

To get to the Eastern Shelter, you need to get a Town Portal Scroll first. The initial spawn rate for this item is quite high, but I just haven't been able to get one. Yesterday, I even upgraded the market to level 2 and increased the number of spawn slots from ten to twenty, but after several attempts, I still haven't gotten a Town Portal Scroll.

Each refresh costs 500 units of Source Crystals. Even though he was a big shot who had possessed tens of thousands of Source Crystals, he dared not continue after spending money a few times. This was no longer spending crystals, but spending his life...

Tang Yu felt that he had bad luck yesterday, but today he managed to get rid of the parasites in the shelter and also fought off a wave of demonic beasts. His luck should be pretty good. As long as he draws a return scroll and makes some preparations, he can set off for Lin Dong.

He first glanced at the goods that had been displayed today. Some of them were quite valuable, but they were too expensive for him to afford. He figured he had to wait until he was a true big shot with over 100 million source crystals before he could even look at those things. Otherwise, it would be too painful for him to bear.

I can't afford to get hurt, I can't afford to get hurt.

brush!

Starting from the first grid, the items are refreshed one by one.

Intermediate Timber Resource Package (500 units) Price: 49 Yuan Crystals

Remaining quantity: five.

Price of Feilian (weapon) crafting blueprint: 3,000 Source Crystals.

Remaining quantity: 1.

……

……

The price of the fruit from another world: 100 Source Crystals.

Note: A very delicious fruit.

Remaining quantity: fifty.

Skill Runestone (Burning Heaven and Boiling Sea) Price: One million high-purity source crystals.

Remaining quantity: 1.

……

The first refresh, unsurprisingly, didn't even bring up a return scroll. However, there were some decent items, such as the Feilian weapon crafting blueprint... If Tang Yu had plenty of source crystals, he would definitely buy as many blueprints as he could. Buying them wouldn't be a loss, they would retain their value, and at the very least, the research institute could use them to research and synthesize new blueprints.

Unfortunately, he has very few Source Crystals.

Other things, like the fruits from another world, Tang Yu could only say that there were more and more bizarre items appearing after the market rose up, but the probability of getting high-level items was also much higher, such as skill runes... This was the first time skill runes had appeared in the market, but Tang Yu calmly ignored them.

One million? And high-purity source crystals at that?

He can't even come up with a million, let alone something like high-purity source crystals; he's never even heard of them!

After losing everything for the first time, Tang Yu took a deep breath. "Don't panic, don't panic. I even got something worth a million, which means I'm still incredibly lucky. A few return scrolls are nothing!"

…………

A few minutes later, Tang Yu was pale, panting heavily, and sweat was pouring down his face.

He couldn't remember how many times he had refreshed, but those few Town Portal Scrolls just wouldn't appear. Was it because Town Portal Scrolls were too cheap, so they were considered unlucky and only lucky players could get them?

What's even more infuriating is that after refreshing so many times, he still managed to get some good items. These items were reasonably priced and quite helpful to him at this stage; in short, they were incredibly tempting, and he couldn't resist... and bought them.

He swiped the bot countless times and bought a lot of things along the way. In just a few minutes, the amount of Source Crystals in his hand had shrunk by more than half.

This is even worse than Taobao!

At least he bought what he really wanted on Taobao, but what about this lousy market? It's always tempting him with flashy, cheap stuff. If this keeps up, he might not even be able to buy a return scroll and will probably have to go back to his old days of poverty.

This won't do!

Tang Yu returned to the castle, took a bath, changed his clothes, and burned... paper. He couldn't find incense, so he could only use rolled-up paper in the shape of incense sticks as a substitute.

They returned to the market.

"The Three Pure Ones, Buddha, Lady Luck, the Lord of Fortune, Senior White... whoever it is, please grant me the power to draw a recall scroll!"

Tang Yu closed his eyes, then opened them.

Bring your two fingers together to form a sword shape.

brush!

Starting from the first item in the product list, a white light swept across, and the items had already transformed into a completely new look.

The bones of a high-level demonized beast.

Spring water brimming with powerful vitality.

It explains the basic knowledge of using source capabilities.

Energy level beam gun manufacturing blueprints.

A scroll that increases summoning probability...

They are all top-notch!

Tang Yu sadly discovered that it seemed the time for another major hemorrhage had arrived.
