Eventually, Sivi had to hear from the people who were transporting the stone and timber to see if they could bring the person in charge of business in their shop to negotiate the purchase of an additional batch of iron ingots near the floating island.

This time the delivery came from yesterday, and after chatting with Xiwei for a while, he said that he could try to help Xiwei ask, but whether it would succeed was not something he could guarantee.

"After all, the thoughts of those noble lords are not something that we civilians can speculate." The man said with a wry smile.

Even if he has been favored by the top of the Chamber of Commerce through hard work and his more sleek and sophisticated way of doing things, it does not mean that he has entered the upper class.

For those large chambers of commerce that monopolize the right to sell some resources in various ways, ninety percent of their upper echelons are big aristocrats with complex networks.

No matter how good a commoner is, he is just a commoner from beginning to end, even if he breaks into a huge family business, ordinary nobles can make it disappear as long as they hook their fingers, so it is basically impossible for a commoner to be in the upper echelons of the Chamber of Commerce, and it is already very good for a man to be able to speak......

And this kind of big nobleman may not have any interest in the sale of a little stone, timber and iron ingots, and it is estimated that the best result is to let some of his men come to negotiate with Xiwei.

"Well, then I'll trouble you." Xiwei didn't insist on it, but then he said to the man as if he remembered something: "By the way, if your Chamber of Commerce is not interested in this transaction, you can go to Luo Lan's Auction House." Ask them to buy a batch of iron ingots for me. Should you just report me Alphonse? Edric's name will do the trick. ”

After all, the other party showed favor to him yesterday, and it doesn't matter if he makes a little innocuous request at this time, especially if he sells personal favors to them. Anyway, Xiwei also has a lot of unused white ordinary-level equipment in his hands, and when the time comes, he will throw them away from the auction house and sell them, so it shouldn't matter if he has a long reputation for them.

The man agreed suspiciously, and left with the convoy.

This time, the convoy was only about one-third of the way, and it would take another batch to deliver all the stones and timber ordered by Xiwei. And that man probably planned to take advantage of this stall to go to the shop of the Chamber of Commerce in the city and discuss it with the people inside.

After waiting for them to get away, Sivi packed the pile of stone and wood into a storage box and took it to the Floating Island.

Although the sky corridor has been almost built, there are still many places where stone and wood are needed.

For example, many places need to be resurfaced with stone floors. Before the iron ingots arrived, some of the underground pits that were still being excavated had to be framed with wood like the pits on earth.

After stacking the materials in the old place, Sivi walked into one of the huge pits, and couldn't help but frown as he looked at the dust that fell from time to time overhead.

Mines on Earth need to be built in addition to a load-bearing framework. It is also necessary to pour concrete to improve the collapse resistance of the pothole, and even then there will be news of the collapse of the mine from time to time. And although there are also alchemy products similar to concrete in this world, the price of that thing is not cheap, and the output is not high.

After all, in the world dominated by magic, the effect of concrete is really a bit chicken, and even if it really makes concrete, I am afraid it will not be able to withstand the smashing of ordinary second-ring magic.

But the academy established by Xiwei is also an academy at any rate, and it would be ridiculous and generous if it couldn't even compare to the safety of the mines on the earth.

"I think cement seems to be made of limestone, clay, and gypsum......" Sivi muttered to himself.

Of course, as I said earlier, cement is not suitable for this worldly realm, and all he wants to do now is to build the mysterious birthplace. After making yourself alchemy, you can improve the cement of the original earth to make it stronger. …,

But now is not the time to dwell on cement. Sivi put the thought aside for a moment, and walked briskly into the depths of the pit.

Leprechauns seem to have night vision, and even the absence of a light source has little effect on their vision, which is probably why they are shy by nature and like to haunt in the dead of night.

But Xiwei can't do it, at least now he doesn't have his own night vision function.

Summoning a whirling flame bolt to float around him, he was able to keep going without crashing into the wall.

This is the underground of the main island, and the tunnels are twisting and turning, and the total length of Xiwei is nearly three kilometers. But unfortunately, Sivi still didn't see the end of the tunnel, but ran into a leprechaun halfway through.

Sivi's recruitment ticket recruited a total of five leprechauns, but the only one he was most familiar with was Woda, and the others hadn't spoken to him much, so Sivi was stunned when he saw each other before asking, "How is the progress of the project now?" ”

"It didn't go well. Mr. host. The leprechaun with what resembled a miniature bowler hat took off his hat and hugged it to his chest, and the expression on his face profoundly interpreted the word sad face: "There have been collapses in three places." In many places, the walls and ceilings were unstable, and at one point when Woda was buried by the sand that had fallen from above, and the rabbi had warned him that he couldn't dig there! ”

"That's right."

Sivi sighed and couldn't help but scratch his forehead in annoyance.

If this continues, it seems that even if you keep digging, it will be useless, just a waste of time.

After thinking about it for a while, Sivi instructed the little leprechaun who was still chattering about something, "Forget it, let's wait until the iron ingot arrives, and you go and let everyone else gather on it." ”

"I see, Mr. Master." The leprechaun with a face bowed to Sivi and disappeared with a pop.

Sivi turned around and set himself a wind elemental ring magic that could be accelerated, and then began to walk back.

By the time he got back to the ground, the leprechauns were already waiting for him in a line.

Sivi handed them the two achievement building blueprints he had bought in the achievement shop when he was on his way, and asked, "How long will it take for you to help build these two?" ”

The two achievement buildings are the Fountain of Sacred Chant and the Sacred Stone of Destiny.

The former is a large fountain that automatically generates a water source, and the water inside also has blessing, purifying, and healing effects, but the effect disappears after five minutes from the fountain. Even so, the building is a good building in terms of both aesthetics and practicality.

The latter is a large piece of jade, which has only one effect, and that is the ability to purchase and bind the Homecoming Crystal in reality instead of in a dungeon. Although judging from the explanation, the price of the return crystal is very expensive, and the cooldown time after using it once is as long as three days, Xiwei, who has saved his life countless times in the dungeon because of the timely activation of the return crystal, knows very well that it is absolutely worth exchanging a chance to live at such a price!

To put it simply, these two are the fountain and the stone that can make people return to the city, both of which have a good effect, and their prices are also very good-the original achievement points of Xiwena, which was relatively rich, have once again become a pitiful single digit after purchasing these two blueprints......

However, the achievement building does not require additional building resources, and both of them have irreplaceable effects, which makes Sivi feel that his achievement is not a loss.

The leprechauns looked at the architectural drawings, then looked at each other for a while before Woda said to Sivi, "Master, these two buildings are not too difficult, if we do them together, it will only take three hours at most to complete." ”…,

"So fast?" Sivi was taken aback, he thought that it had taken more than ten hours to renovate the room before, and now it would definitely take a lot of time to build these two buildings, but he didn't expect it to be unexpectedly fast......

"Because they are small buildings and you don't have to waste time processing materials, they are relatively quick to build." Voda explained to Sivi.

Sivi calculated, in three hours, the convoy must still be halfway there. And even if there is no iron ingot, it is useless.

In addition to the fountain and the Huicheng Stone, the achievement building in his hand now has a mysterious birthplace, a star vein furnace, and a magic engine, the latter two of which are the core parts of the Sky Academy, and it is more reassuring to be built underground than to be exposed. Therefore, it is not possible to start building now.

After thinking about it for a while, Sivi immediately made a decision.

"Woda, you and your buddies divide the work, some of them will build these two buildings, others will dig rivers on the island, and the last part will help me build other things."

"Digging a river?" The leprechaun tilted his head in confusion.

"There is no river on the floating island, so when the Sacred Chanting Spring is built, we don't have to worry about the water source, we can divert the water from the inside to the outside and form a small river. I just saw a small pond with fish at the back of the castle, and I can connect it in series, and anyway, there are a lot more stones, and I can connect the waterway under the air corridor, so that a huge water system can be formed between the islands, and if you can't make a water cycle, you can drain all the water out of the island at the very least. ”

Sivi explained to the leprechaun.

He didn't just build the fountain for the beauty of it and the effect of the fountain water, as long as the river could be built, the construction conditions for some special buildings such as the forbidden forest and the lair of water beasts could also be satisfied.

"And what else is going to be built?" The leprechaun asked again.

Sivi didn't answer, but handed it the construction blueprints of the [Mysterious Birthplace].

"Got it, leave it to us!" After watching it carefully a few times, the little leprechaun immediately patted his chest and assured Sivi, "In five hours at most, we can get everything done!" (Your support is my biggest motivation.) )
