The magic tide comes and goes in a hurry, like a conscientious courier, leaving the love and warmth here.

Fortunately, Yuanjing, as a common currency in the new century, is stronger than Tang Yu's expectations. In the endless destruction of artillery and arrow towers, these source crystals are still intact, even because of these demonization. The corpse of the beast is destroyed, broken, and the source crystal is quite convenient to clean up.

It's not bad to be like this again in the future... an egg!

He still loves those materials. Not only can this thing be used to make equipment, but more importantly, it will soon be going to Lindong. There is always a market for a shelter as big as Lindong, right? Tang Yu is also looking forward to making a fortune.

In addition, there are some powerful demonized beasts whose body materials are relatively well preserved. Tang Yu ordered people to collect these materials, and he counted the profit of this battle.

The demonized beast brought so many source crystals, this money must be earned, but this wave is not without losses.

Just to build these defensive buildings, regardless of the materials, the source crystal cost 2,000. Not only that, but it also consumes energy when defending against building attacks.

Where does this energy come from? Of course, it came from Yuanjing. Tang Yu stored some Yuanjing in the small warehouse that came with the castle. This was the consumption of defensive buildings. Otherwise, he wouldn't have waited until now to build defensive buildings.

Tang Yu remembered that there was a building in the third-level territory called an energy patio, which could absorb the free energy in the air to replenish energy for the defensive buildings. Probably before this building was built, these defensive buildings were all big players.

After all, he made money. Tang Yu was in a very happy mood. In addition to the previous plunder at the Yuanjing Mine, there were already a lot of source crystals. Before going to Lindong, these source crystals must be spent on the most appropriate ones. place.

The other survivors were also happy.

This is the afterlife.

The city gate has been reopened, and the brave survivors stepped forward to observe the corpses of the demonized beasts up close.

"God, it's so big! Such a big demonized beast is dead!"

Ordinary survivors have had close contact with demonized beasts. Immediately, survivors poked and found that they were really hard.

So many terrifying demonized beasts attacked, but they were successfully resolved by the shelter.

A shelter for less than a hundred people.

Such a record, who would dare to believe it? Although most of this is due to Director Tang, it does not hinder it, this can become the capital of their boasting!

In the past, many ordinary survivors could only eat and wait to die every day, but now it is different. As long as you work hard to eat well every day, and now you know the ability of the shelter, even the magic tide can't help it. , is there a safer place than a large shelter?

Before they knew it, the survivors felt a sense of belonging to the shelter and were genuinely lucky to be here.

…………

After the magic tide was over, Tang Yu was not idle, leaving things outside to Chen Haiping and Luo Zhe, and he came to the back of the castle alone, the area used to build system buildings.

In the core four-piece set, the tavern, workshop, and market have all been built, leaving the last research institute.

Tang Yu asked No. 1 and No. 2 to transport materials back and forth, and finally saw that the construction conditions on the panels were satisfied.

"Constructing the research institute will consume 1,000 units of source crystals, 100 units of wood, 300 units of stone, and 300 units of iron."

Just like the previous few times, a three-story building quickly appeared in front of Tang Yu's eyes.

walk into it.

There are all kinds of research equipment in the institute. Tang Yu looked at it and knew very few of them. It was just a beaker, the kind used in high school experiments. It's all a cup.

None of this matters, what matters is the function of the institute.

As an important functional building, the research has its indispensable status.

Researching and developing blueprints, strengthening blueprints, transforming blueprints, etc. are all functions of the research institute. In theory, only with sufficient knowledge and source crystals, the research institute can completely develop the blueprints it wants.

That's a long way off.

At present, the level of the research institute is low, and Tang Yu is not going to invest too much source crystals, mainly using its function of transforming blueprints.

Such as the basic long sword, this kind of blueprint comes with the workshop, which is very inhumane. What if someone else wants to use a knife, or other weapons? !

Transforming the blueprint is to change the blueprint of the long sword into the blueprint of the battle knife. Of course, the level remains unchanged, and it is still the basic equipment of a rune, but it has more applicability.

Not only that, for example, the basic material used in the long sword blueprint is iron. After the blueprint is transformed, you can add magical beast materials, such as magical beast claws, bones, etc. Although the level of the blueprint has not changed, the materials are better and the production The weapons that come out are naturally more useful.

Tang Yu first transformed the blueprint of the battle knife, and then designed a whiteboard shield blueprint and gun bullet blueprint without runes. With the blueprints, they can be manufactured in batches in the workshop.

After finishing the research institute, he didn't need to build any more, and instead came to the market.

He didn't choose to build a system building anymore, it wasn't that he didn't need it, but it was... virtual.

In order to go to Lindong Sanctuary, you must first brush out the City Return Scroll. This thing obviously has a high chance of being refreshed in the early stage, but he has never been able to brush it out. For this reason, the market was upgraded to level 2 yesterday, and the counters increased from ten to ten. The refresh vacancy has risen to twenty, however, after several times of brushing, the City Return Scroll still does not appear.

A refresh is 500 units of source crystals. Even if he is a big man who has held ten thousand source crystals, he does not dare to continue after a few times. This is no longer a krypton crystal, but a life of krypton...

Tang Yu felt that yesterday's fate was wrong, and it happened that today he solved the moth in the shelter and attacked another wave of demonized beasts. He should be lucky. As long as he draws the return scroll and makes some preparations, he can set off. To the east.

First of all, I took a look at the goods sold today. The value is quite high, but it is too high. Look at those things, otherwise your heart will hurt and your eyes will hurt.

Can't afford to hurt.

brush!

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

Intermediate Wood Resource Pack (500 Units) Price: Forty-nine Origin Crystals.

Quantity remaining: five.

Feilian (weapon) making blueprint price: 3,000 source crystals.

Quantity remaining: one.

...

...

The price of fruit from another world: 100 Origin Crystals.

Notes: Very tasty fruit.

Quantity remaining: fifty.

Skill Runestone (Burning the Sky and Cooking the Sea) Price: One million high-purity source crystals.

Quantity remaining: one.

...

The first refresh, unsurprisingly, I didn't even see the shadow of the City Return Scroll, but there are some good things, such as Feilian's weapon manufacturing blueprint... This blueprint, if the source crystal is abundant, how many Tang Yu must have If you buy too much, you won’t suffer any loss if you buy it. If you buy it, you can still keep the value. No matter how bad the research institute is, it can be used to research and synthesize new blueprints.

It is a pity that his source crystal is very insufficient.

For other things, like fruits from another world, Tang Yu can only say that more and more exotic products have appeared after the market has risen, but the probability of spawning high-level items is also much higher, such as skill runes... This is still For the first time in the market, skill runestones were generated, but Tang Yu was very calm and ignored it.

one million? Also high-purity source crystal?

He can't come up with a million, let alone a high-purity source crystal, I haven't even heard of it!

The first time I lost everything, Tang Yu took a deep breath, "Don't panic, don't panic, even brushing out a million worth of things, it means that I'm still the Emperor of Europe in essence, just a few scrolls back to the city, that's not a problem. !"

…………

A few minutes later, Tang Yu's face was pale, he was gasping for breath, and sweat dripped from his face.

He doesn't remember how many times he refreshed himself, but so few return scrolls did not appear. Could it be that the value of the return scrolls is too low, so it belongs to the category of non-Emirates, and the European Emperor can't get them out?

What's even more irritating is that after brushing so many times, I was lucky enough to get some good things. The price of these things is moderate, and they are very helpful to him at this stage. In short, the temptation is huge, and he can't hold back for a while...

I don't know how many times I swiped, and I bought a lot of things in the middle. In just a few minutes, the source crystal in his hand has shrunk by more than half.

This is simply more pit than a treasure!

Anyway, some treasure is still the most wanted thing, but what about this broken market? Always get some coquettish cheap goods to tempt him, and if this goes on, he will not buy the City Return Scroll, and he is afraid that he will have to go back to the poor days before.

That does not work!

Tang Yu returned to the castle, took a bath, changed clothes, and burned the paper. The incense was not found, so he had to roll the paper into an incense shape instead.

back to the market.

"Sanqing, Lord Buddha, Goddess of Luck, Lord of European Emperor, Senior White... Whoever it is, please give me the power to draw the City Return Scroll!"

Tang Yu closed his eyes and opened them.

Put your fingers together to form a sword.

brush!

Starting from the first commodity column, the white brilliance swept across, and the commodity has changed to a new look.

The bones of high-level demonized beasts.

Spring water with powerful vitality.

Describe the basics of the use of source capabilities.

Energy level beam gun making blueprint.

A scroll that increases the probability of summoning...

All are superb!

Tang Yu found sadly that it seemed that it was time for hemorrhage again.
