In the face of everyone's heated discussion, Lu Haoyu didn't care at all, and took Hou Xiaoxian alone to inspect the metal materials that Ye Guchen prepared for them.

Although Ye Guchen didn't know what sand and gravel were used for, he knew that the main material of the Divine Mind Instrument was metal, so he didn't dare to be careless, plus the third row itself was a scientific and technological platoon for building weapons, and originally stored a lot of conventional metal materials, and there were eight piles of metal in the material storage warehouse.

These eight piles of metal are made of different materials, and even the forms are strange. The largest pile is a mountain of primary iron, which is the raw material for smelting, as if it had just been mined, and seems to have been preliminarily processed, forming pieces of square iron ingots, which are stacked together in a regular manner.

Lu Haoyu was curious, where did Ye Guchen mine such a large-scale pig iron, could it be that he went to the mine to dig it himself in his spare time?

What he didn't know was that these pig iron were also a valuable resource among the ordinary civilians of the Xuanwu Empire, after all, most of the minerals were occupied by the imperial army under the empire, and civilians were not allowed to mine them privately. Not to mention that Lu Haoyu is an orphan and has not yet become an adult, even if he is an ordinary college undergraduate, if he wants to own pig iron ore to refine equipment, he also needs to exchange resources such as divine thoughts.

The remaining seven piles of metal include slender silver bars, copper ingots, and entire sheets of thick aluminum, as well as some rare metals, but most of them are components of scrap metal, and their purity is not high. The last pile is a variety of alloy components, which may be difficult to smelt directly, and it may be even more difficult to form the mechanism parts he wants.

Lu Haoyu squatted in the last pile of messy piles of various metals and searched for a long time, and found seven or eight special metal blocks that could be used, but unfortunately these metals were of lower purity, and if he wanted to purify the alloy, Lu Haoyu was very skeptical that the primary smelting he was now mastering could be done.

In the end, he raised his head, put his eyes on Hou Xiaoxian's body, and said with a smile: "Is this all that Ye Guchen prepared for me?" How do I feel like something is missing? Tell me honestly, whether you have been embezzled. ”

"No, no, how dare I embezzle what the master used, you framed me."

"Framed? Your heart is beating three times faster than usual, and there is a hint of confusion in your eyes. In addition, although your cultivation is higher than mine, I can sense the fluctuation of your divine thoughts, although it is only for a moment, the power of the divine thoughts that permeate is very huge, at least surpassing the tenth level of the forging body Deputy Head Lu. If I'm not mistaken, there must have been a slight struggle in your consciousness that you wanted to keep some particular substance for yourself? ”

Lu Haoyu revealed a series of secrets that made Hou Xiaoxian smack, how did he see my flaws?

He is just a forging body level 2, and Hou Xiaoxian is more than a dozen realms higher than him in terms of cultivation, why can he perceive so many changes in his body, Hou Xiaoxian subconsciously wrapped his clothes, and he suddenly had a feeling that he was being looked at.

"Don't worry, I'm not interested in men." Lu Haoyu pretended to be very mysterious, he could have such a profound eyesight, and he had some connection with the previous life, but the most important thing was that he was related to the level 1 of physiognomy downloaded from the essence of science and technology a few days ago.

The first level of physiognomy is mainly about the observation of people, not to mention that Ye Guchen is more than a dozen small realms higher than him, even if there is a larger gap, the slight changes in the other party's body will make Lu Haoyu notice.

Ye Guchen was stunned, he didn't dare to underestimate Lu Haoyu anymore, he hesitated for a moment, and finally gritted his teeth and held a black metal ball in his palm.

When Lu Haoyu saw this, he suddenly came to his senses, and his intuition told him that this black metal ball was extraordinary.

"Tell me, what is this?" Lu Haoyu added his lips, although he downloaded the smelting, he didn't know the origin of this black metal, there was only one possibility, this thing was beyond the scope of his contact with the Heavenly Dream Troupe, and it was something that the universe did not have, and it was even very likely to be above the three major artifacts "Soul Heavenly Instrument", "Flesh and Blood Machine", and "Divine Mind Instrument". After all, the three major artifacts he had come into contact with, as long as the metal contained in them, the essence of science and technology could be directly recognized.

"You don't know what it is?" Hou Xiaoxian showed a look of surprise.

"Should I know?" Lu Haoyu was a little surprised.

"It shouldn't be, it's obvious that he is a person with a great background, with the inheritance and memories of his previous life, and it stands to reason that he shouldn't not know this piece of extraterrestrial meteorite in his hand." Hou Xiaoxian was puzzled and began to tell him about the origin and efficacy of this meteorite.

Extraterrestrial meteorite, not owned by the continent, comes from extraterrestrial meteorite, its hardness is comparable to the pinnacle metal on the road frame, at least in the territory of the Xuanwu Empire, there is absolutely no metal that can compare to extraterrestrial meteorite.

Lu Haoyu didn't show any surprise after hearing this, but nodded slightly, "It's a pity that this piece of meteorite is too small, only Hou Xiaoxian's palm is the size of a palm, and in the eyes of humans, it is just a small bead with a diameter of one millimeter." ”

"What, you are still disgusted, although this piece of extraterrestrial meteorite is not big, but in the outside world, it is priceless, if it is sold in the church, it can at least be exchanged for tens of billions of divine thoughts, enough for our army to eat a large cake for several lifetimes. And even if it is put in the auction in the church, this kind of rare thing is not always available, and even has no price. ”

Hou Xiaoxian was very unwilling to hand over the meteorite from the sky to Lu Haoyu, it was obvious that he was still a little reluctant, if this meteorite was made into a weapon with a sharp blade, his cultivation could even be improved by a few grades, and it would become his hole card at the bottom of the box.

But he guessed that this thing in the hands of 9527 might be of greater help to the Heavenly Dream Group, and this was left to him by Ye Guchen, not for himself, he even had some jealousy, he had taken refuge in Ye Guchen for three years, and he was not as important as a student who had just been born for a few days.

Lu Haoyu took the meteorite from the sky, feeling its specialness, the palm-sized ball weighed nearly a hundred catties, if it weren't for the infinite strength of his left hand, it would be difficult to hold this meteorite alone. But Hou Xiaoxian actually held one hand in the palm of his hand, and he hid it in a certain part of his body before, which shows that his strength is no longer under himself.

"What are you going to do with him?" Hou Xiaoxian asked puzzled.

Lu Haoyu struggled to shake the meteorite twice, and then lightly scratched the edge of a copper ingot next to him, and the contact surface of the copper ingot was suddenly scratched a deep trace.

"Very good, I decided to use him to make a machining tool for metal cutting." When Lu Haoyu said this, he felt a little proud in his heart, and he finally broke through one of the major problems that had been surrounding him.

When Hou Xiaoxian heard his words, he almost didn't fall on his back, he regretted it in his heart, he shouldn't have handed over the meteorite to him, such a precious metal, where can it be used as a cutting knife, this is absolutely a tyrannical thing.
