Mu Jianfeng and Binglu spent a warm afternoon, and after eating, Mu Jianfeng didn't go anywhere, but talked to Binglu, telling her the jokes he knew, all kinds of astronomy and geography, and cultural wonders, which made Binglu laugh again and again.

This feeling is something Mu Jianfeng has never had, in the afternoon spent with Binglu, Mu Jianfeng put aside all the pressure, did not think about how to worry about the future, but enjoyed the world of the two of them wholeheartedly.

Binglu also told Mu Jianfeng a lot of what she had seen and heard, such as how she escaped from those masters of the Longxiang Empire, how many beautiful women and how many handsome guys there were in the Royal Academy of Magic in the Tiancang Empire, etc., and Mu Jianfeng was also curious when he heard it.

In the chat with Binglu, Binglu once again mentioned the kind of ore that caused the war in Youyun City, because Mu Jianfeng asked people to stop the mining of this ore when he was the patriarch at that time, and after Binglu mentioned it again today, he was also quite interested in this ore, so he planned to take a look at it tomorrow, maybe this ore would be useful to him.

The next day, Binglu's body couldn't feel the pain anymore, after eating yesterday, Mu Jianfeng gave her two holy fruits, plus Binglu is also a martial arts practitioner, so at night, she didn't have much pain there, and Mu Jianfeng, the animal, naturally would not let her go, this battle lasted for 4 hours, until the two fell asleep deeply.

The night of the magic star was 18 hours, and Mu Jianfeng finally didn't wake up in the middle of the night this time, and slept until dawn, of course, this was related to the exercise that Binglu had done for so long.

It rained on the first day of Youyun City, the weather was particularly good the next day, when you got up in the morning, everywhere seemed to be a piece of clarity, the sun hung in the sky early, surrounded by a few white clouds, the blue sky was not stained, and the nine secluded peaks in the distance also appeared in everyone's field of vision, majestic and magnificent.

Mu Jianfeng's spirit today is very good, after Binglu personally sorted out the clothes for this big man, he also went out with Mu Jianfeng, Binglu, who had experienced that kind of thing, looked like he had a different feeling today, well, it's flattering, Mu Jianfeng can confirm it, haha, it seems that there will be more development in the future, he thought badly in his heart.

He was going to take a look at the unknown ore today, so he called the person in charge of the previous mining to take him to see it.

Some of the ore mined before has not been taken out for sale, and now it is piled up in a small and simple warehouse, this warehouse is built in the back of Youyun City, which is relatively close to the mining place, and this place is easy to defend and difficult to attack, so the patriarch chose the address of the warehouse in this place at that time.

The person in charge opened the door of the warehouse, and suddenly a musty smell wafted out of it, Binglu hurriedly covered his mouth, and Mu Jianfeng also fanned it with his hand.

"Patriarch, this is that kind of ore, and there are so many left." After a few people entered, the person in charge respectfully pointed to the pile of things and said.

Mu Jianfeng walked over, reached out and picked up a fist-sized piece of ore to take a closer look, this kind of ore showed a light purple color, even if it was an irregular shape in his hand, he felt very slippery in his hand, and he would get out of his hand if he was not careful.

"This ore is really weird, I've never seen it before." Putting down the ore in his hand, Mu Jianfeng patted the ash on his hand and said.

"Wow, young master, you're here." Xiao Yi's words sounded in Mu Jianfeng's mind at this time.

"Sent it? Xiaoyi, you can make it clear, are these ores in front of you? Mu Jianfeng was a little surprised, and Xiao Yi suddenly spoke at this time.

"Yes, I tell you, this kind of ore is very rare in the universe, it is a key material for the manufacture of intelligent machines and intelligent systems, if you get him, then your future path will be much easier." Xiao Yi explained to Mu Jianfeng.

"What? It's very rare in the universe, isn't that priceless, and it's also a key material for the manufacture of intelligent machines and intelligent systems, it seems that my character has really exploded. Mu Jianfeng was ecstatic in his heart, now he didn't have to buy a machine from Tianlong, so as not to make himself suffer a dumb loss every time.

"Well, young master, you can store these materials well, my database now has the technical information of the smart machine, and you can make it yourself when the time comes." Xiao Yi said again.

"Haha, okay, I want as much of this material as I want, Xiaoyi, you are really my good housekeeper, haha." Mu Jianfeng said, "By the way, Xiaoyi, what is the name of this ore?" ”

"This is not necessarily, it has a different name on each intelligent planet, why don't you choose a name for it, young master." Xiao Yi tilted her head and said.

"Well, that's it, wait for me to think about it." Mu Jianfeng pondered, "It's better to call it the Demon Mine, this is found on this planet, and it is more appropriate to choose this name." ”

"Well, okay, whatever the young master."

"By the way, Xiaoyi, I don't understand it, that's why in addition to what you said is the key material for making intelligent machines and intelligent systems, people on this planet also use it to make flying swords, what is the principle, I can't figure it out." Mu Jianfeng heard that this material was remembered by those masters, and they were used to make zuò flying swords.

"That's right, this material is also a kind of superconductor, after they refine it, and then inject their fighting qi or internal force, you can make the flying sword made of this material produce magnets, and the air here contains an element that other planets don't have, so the flying sword can interact with this element, I think you also know that the main energy in the crystal nucleus of those demonic beasts also comes from this element, so it's not difficult to understand." Xiao Yi explained again.

"Now I understand, can I say that if the flying sword here is taken to the earth, and the internal force and fighting energy are also injected, it will not be able to fly." Mu Jianfeng asked again.

"That's right, so the flying sword can fly, the key is to have that kind of gas that is not found on the earth."

"Well, I understand, it seems that the universe is so big, there are no surprises." Mu Jianfeng couldn't help but sigh.

"That is, there are many kinds of planets that you haven't seen before, and when your strength is improved and upgraded in the future, you will know how colorful this universe is, and you can see it for yourself when the time comes." Xiao Yi said.

"Okay, I will definitely work hard to improve my strength and work hard to upgrade." Mu Jianfeng suddenly had a confidence in his heart that he had never felt before.

Binglu and the person in charge next to him looked at Mu Jianfeng and looked at the demon mine in front of him and pondered, but they didn't bother him silently, how did they know that he was chatting with Xiao Yi just now.

"Well, do you have a name for this ore?" Mu Jianfeng suddenly came out of his contemplation and asked the person in charge.

"Yes, we all call him Flying Mine."

"The name of the flying mine is not good, so let's change it to a magic mine in the future." Mu Jianfeng said.

"Well, okay, listen to the patriarch's orders, and I'll go down to tell everyone."

"Also, this kind of ore doesn't need to be sold to other countries in the future, all of it will be sold to me, I will be of great use, and I will pay you the necessary remuneration." Mu Jianfeng said that since he knew the rarity and preciousness of this ore, he would definitely have to firmly grasp it in his own hands.

"Yes, good patriarch."

"You go tell the officials first, so they know too." Mu Jianfeng said.

"Brother Feng, this ore is very important to you." After the person in charge went out, Binglu spoke.

"Well, that's right, this ore is really important to me, I just don't know how many of these things are on this planet." Mu Jianfeng said as he went to pull his little hand, while Binglu dodged it.

"Oh, I hate it, in broad daylight, if someone sees it, then I don't have the face to see people." Binglu struggled with the little hand that was held by Mu Jianfeng.

"Hehe, old husband and wife, why are you shy, besides, I'm the patriarch, who dares to say anything." Mu Jianfeng laughed cheekily.

"Well, I'm ignoring you," Binglu said shyly, turning her head and saying, "By the way, Brother Feng, then what are you going to do with these ores?" ”

"Put it away first." As soon as Mu Jianfeng's words fell, he received all the remaining demon ores in the warehouse into the dimensional storage space.

Next, Mu Jianfeng plans to let the satellites in the sky probe the distribution of magic mines on this planet, this satellite is a multi-functional detection satellite, just wait for the satellite to pass over, Xiao Yi will send a command.

Next, Mu Jianfeng and Binglu together, checked the construction of the new city of Youyun City, due to the heavy rain yesterday, so even the machine qì people did not go out to build, and today they continued to do it, during this time, the people of Youyun City also joined the construction of the new city, the so-called number of people is powerful, and brand new houses have sprung up on the site of the new city on the opposite side of the moat, and the hydropower station is also in the final stage of installing the unit, and then it is the wiring stage.

After staying on the Magic Star for another day**, Mu Jianfeng returned to Earth, and on this day of the Magic Star**, he explained a lot of things to the first and second of the Magic Star, and at the same time revealed his relationship with Binglu to everyone, which made the respect of those officials and the people for Binglu increase by another point, the patriarch's wife, this is the most affordable thing to talk about when the patriarch is not there.

The satellites in the sky sent back the information of detecting the demon mine, and the result made Mu Jianfeng very satisfied, the demon ore is mainly distributed in the Jiuyou Mountain Range, and there are also some other places, mainly in another continent, and in the Jiuyou Mountain Range, the most extensive step is 2100 kilometers away from Youyun City, where the demon ore reserves are very rich, according to Xiao Yi's speculation, nearly 100 million tons can be mined, this is a scary number, although this kind of ore is very rare in the universe, but his character is too good, according to Xiao Yi's words, he is now a cosmic billionaire.

Next, he has to think about how to mine these magic mines, because the Nine Shadows Mountain Range is inaccessible, and the middle age is low and snowy, so those magic mines have not yet been discovered, and now they all belong to him.
