Fast did things quite quickly, and an hour later, a kilogram of spirit vein fragments was handed over to Ou Xiaolu.

However, as Fast said, this thing is used as currency in the underground world, so there are many people who infiltrate it and some people extract the energy inside.

So there was no way to ensure enough energy for this thing, Ou Xiaolu purified and combined it through the system, and in the end only got 771 grams.

According to this situation, one kilogram of such material can only be purified by about 70%.

However, this is enough for Ou Xiaolu, he has never been able to find a way to get gold coins before, so there are many things that cannot be bought, but now it is different.

Ou Xiaolu is about to awaken one of the most common superpowers in American comics, being rich.

Ou Xiaolu has even begun to calculate, when he has money, what to buy, brush two waves of 888 is certain, the world will come in a wave, sundries will come in a wave, if it doesn't work again, then buy other things, preferably more advanced things in the store.

Ou Xiaolu was thinking like this, and Tie Zhongxiao over there also rushed over.

After listening to Ou Xiaolu's spending plan, Tie Zhongxiao shook his head, "It's not enough for you to rely on this little money in your hands, you have to have a mine." ”

As soon as he said this, Ou Xiaolu was directly speechless, yes, just relying on the money in his hand, plus an apartment and a small valley, how many spiritual vein fragments could he buy, even if he sold all the things, he would exchange them for ten or twenty kilograms at most.

And with this transformation, how many gold coins can there be, so as Tong Tie Zhongxiao said, they need to have their own spirit vein mine.

"If there are really so many spiritual vein fragments in the underground of Xinxiang, then there will definitely be ore veins, with our strength, it is not difficult to grab a mineral vein, and the most important thing is that we have someone to mine and protect it." Tie Zhongxiao put forward his opinion, although he was a martial idiot, but after following that for so long, he knew what the army needed.

"It's relatively simple." Ou Xiaolu replied without thinking about it, "I only use one rainbow door in my hand, just open one door there when the time comes." ”

Tie Zhongxiao nodded, "I feel that the person named Fast doesn't seem to want me to go with me, I think so, you are in front, I will follow behind, if you are safe, then I will not make a move, just I can look for it to see if there is a suitable vein, if something goes wrong with you, then I will kill the person named Fast directly." ”

Ou Xiaolu hesitated for a moment, and finally nodded.

At this time, Ah Luo also walked over, "What about this valley?" ”

"There's nothing left in the valley, anyway, these workers are working every day, and it's not going to be completed so quickly, and besides, Booth is still staring at the guild, I believe it will be fine."

Ah Luo is true love for this valley and mountain forest, and at this time he already has a bit of a mountain god, so he is still a little hesitant in the end.

However, for the sake of seeing so many spiritual vein fragments, Ah Luo still agreed to accept this task.

After that, Ou Xiaolu went to find Charles again and asked him to take care of the apartment himself, after all, Elizabeth was there on the other side of the apartment, and Charles agreed very seriously.

As for Amilia, she was very interested in playing at first, but after knowing that the target was the Xinxiang Underworld, she had no plans for the past.

"I know there, my mother took me there, and if you go in the other direction from a subway line, you will soon be able to reach an underground space, where there is an underground black market, and my mother has forged her weapons there.

But I don't like it there, and my mother doesn't like it either, saying that it's like a dwarf's cave, and it's a head lower than a man.

So we've been there a few times and haven't gotten there, why are you going there?

I heard my mother say that the underground world is also divided into several layers, and there is a sewer in the middle of each layer, if you encounter any danger and are not afraid of getting dirty, you can escape from the sewer. ”

Ou Xiaolu nodded, "What time do I probably have to go, in the few days that I am away, you should be careful yourself, if there is anything, you contact Booth directly, and Booth will find me." ”

"Don't worry, my strength is a little bit higher than that of my predecessor, if I am in danger, it is useless for you to come."

"Okay, by the way, this box is for you, I've opened the permission, your dragon eggs are about to hatch, and I have time to go in and have a look."

Ou Xiaolu and Emilia laughed and set a time to prepare for the trip.

At this time, Fast was in a room, contacting his master remotely.

The remote contact used by Fast is not a magic mirror or anything, but a dedicated video.

Since they have money, one wall of the entire room is a monitor, and inside the monitor, it is the treasure trove under the Dragon Castle - Silver Wings, and the countless gold looks like the entire display is golden.

The silver-haired Silver Dragon King was lying on top of the gold, looking at Faster from top to bottom.

"How's it going?"

Fast said very carefully: "It has been arranged, I am going to take those two people to the territory of the Demon Dragon King, if they really kill the young master, there will be a dragon soul phantom in the Dragon Tomb of the Demon Dragon King, and then I will kill them directly, if it weren't for them, then the Demon Dragon King would not be embarrassed by a human being." ”

"Don't arrange it like that, just tell the Demon Dragon King directly, just say that I said it, kill those two people, it is considered that I owe him a favor, in addition, after taking those two people away, you arrange for someone to set up an altar in that valley, I will arrange for the doppelganger to go over, I feel it, my son died there, I want to go over to collect the soul."

"Master, you come here as a doppelganger, it's quite dangerous, do you want the housekeeper to ......?"

"No, I'll handle my son's affairs myself, and besides, those two people are gone, who will be my opponent in that valley."

"I found a man today, and his strength is bottomless."

"That should be that person's bodyguard, he will definitely follow him to the underground world, leave him alone."

"All right, but master, you really don't need to call a butler or any other deacon?"

"I'm the master or you're the master, do it right away."

At the roar of the silver-haired man, Fast quickly retreated.

However, the Silver Dragon King didn't notice that Fast's eyes were full of disdain, and after walking out of this door, he also said, "Silver Dragon King, soon you will become the Bone Dragon King." ”
