Liu Bu carefully inspected the metal blocks and thin plates that Wei Guizang took out, took out iron scissors, cut a small thin plate, looked at Yuan Tiangang, and said, "Yuan Gong, borrow a fire." ”

Yuan Tiangang rubbed his fingers very cooperatively, and a small pinch of flames ignited, and the small sheet soon burned violently, and emitted a dazzling white flame, which melted and dripped onto the floor, and the iron shears did not change at all.

"It's tough, it's lighter than iron, I can try to make some utensils." Liu Bu looked at Li Yuanying and asked. "What does King Teng think?"

Li Yuanying: "......"

The use of something you know, which you can't do, can be drawn into a wire to conduct electricity, and you don't know what electricity represents except for lightning. You can make car engines and shells, and you can also make airplane wings, so you can make steam engines...... "Lighter than iron, can it be used to make steam engines?" ”

"Wait, Yu Gong asked me to ask if I could make a withering board, if it would be more durable than a wooden board." Wei Guizang heard the steam engine and hurriedly spoke. Once it is found that it can be molded like bronze and iron, with Liu Erlang's character, he will not consider the problem of carving handwriting at all.

Liu Bu took the scissors and slashed across the thin board, leaving only a mark, and looked at Wei Guizang without speaking.

Wei Guizang: "......"

The people of the Shushan Sword Sect are very annoying!

Yuan Tiangang looked out the window and saw the lark that had flown back, the corners of his mouth rose slightly, and he continued to look at the small piece of metal, picking it up and kneading it curiously...... Much softer than iron, soft means it can cushion impacts, and it can cushion impacts means ......" Liu Erlang, test it in water, including seawater. Zhang Guo will go to find mineral deposits with Wei Jue tomorrow and bring more ore...... It is best to see if there are such deposits near Chang'an. ”

If there is no near Chang'an, you need to consider the transportation problem.

Li Yuanying picked up the jade in the wooden box and looked at it, the tentacles were slightly cool, translucent to transparent, clear as ice, giving people a feeling of ice and jade. The green ribbon is like a touch of fresh green in the treetops in spring, cut into slices more than a finger thick. It can only be said that the ore found by Wei Sanyang is of really good quality.

What is the best thing to do? The small bun is too small to wear a jade bracelet, but you can make a safety buckle or only take the part with a green belt to make a bead chain. Later, when the literary game was more popular, there were many reports on various wood aspects in the news, and they were all similar to UC shock headlines, such as "A villager in a certain place inadvertently dug up ebony worth tens of millions", "A villager in a certain place actually lived in a mansion worth tens of millions", etc., and after the early reports, it was written that their fate was: car beads.

As a result, in those years, everything could be cared for beads, and then everything could be plated. Fortunately, it finally cooled down. The development after cooling down is unexpected, and soaking wolfberries in a thermos cup with a string in the left hand and the right hand has become the standard for middle-aged uncles.

Goji berries are a good thing, you can grow wolfberries on the edge of the desert and gradually push them in, as well as along the Yellow River, Ningxia Red ...... Find time to look at the map, a certain fishing old man who knows a little bit of everything, and is not a person with a certain degree of system plug-in, how can he know everything?

"Yuan Gong, it can be made into gear teeth and used in the mechanism." Ban Qian saw the metal block in Yuan Tiangang's hand that had been pinched into a cup, and said softly. "It can also be made into axles or wheels to reduce the burden on the horse."

PS: In 1953, a pair of bronze herringbone gears were unearthed in Hongqing Village, Gaoguan'an County, Shaanxi. According to the analysis of the tomb structure and tomb items, it can be determined that this pair of gears came from the early years of the Eastern Han Dynasty. Both wheels are 24-toothed and about 15 mm in diameter. The same herringbone gears have also been found in Hengyang and other places.

As for other information, you can go to a certain degree to find it yourself, and a certain sweet potato will not have the number of words, as for writing the above content...... (,,?w?,,) Eat melons.

Yuan Tiangang looked at Zhang Guo and sighed softly: "You better set off now, the mine doesn't know where it is, and there are several places for use." ”

"You'd better give me a token, Wei Saburo doesn't believe me." Zhang Guo shook his head and said. The thinning hair swayed as he shook his head, with the grace of detachment from the grass.

Yuan Tiangang took out a talisman from his sleeve and said, "Go, go early and come back early." ”

As for the transportation of the stone grease, it is not too late to wait for him to return. His white donkey is very unusual.

Sun Simiao saw that Zhang Guo had left, so he picked up Wei Guizang and said, "We should also go back and continue to study other ores, and let them discuss the remaining two for themselves." ”

You don't need to say anything to King Teng, just do things well, he naturally understands so.

Wei Guizang: "......"

Come over with you to watch Zhang Guo leave!

Yuan Tiangang ignored the two people who left, looked at the other piece of silver-white metal in the wooden box, and picked it up...... Heavier than gold? Finger kneading...... Harder than gold? Use iron scissors to cut and not move. With a gentle rub of fingers, the flames burned to the metal and iron scissors...... The tip of the scissor melts, and the piece of metal falls off.

…… Li Yuanying stared blankly at the falling metal block, this can't be platinum, right? Shouldn't it, isn't platinum hard to get out of ore? And the content is very low, I have seen the video of mining in Continent F, the content is only 1.5 grams per tonne, and it is at a depth of 250 meters. Such a big piece...... I don't think I have shipped much ore, huh?

Then there is only one truth: he sent not platinum mines, but meteorites, meteorites rich in platinum.

Because the moon and meteorites contain the most platinum, there will be higher platinum abundance in areas of the Earth that erupt after a meteor impact. So, when a man says to you that the moon represents my heart, it may not be that the moon is cloudy and sunny, but more likely that his heart is like platinum that never fades.

Of course, you have to help him get rid of all that messy impurities. After all, how much platinum is there...... Just relatively.

The reason why I understand is because a certain friend, a senior sea king, has deceived many beautiful girls with this sentence.

What a friend, not a friend out of nothing! So-and-so is just an old fisherman. As for the single Wang...... Uh-uh, people who aren't married, they're all single, right?

Well, that's it, that's right, fishing old words, don't accept refutations, who wants to refute, see you in our school playground...... A certain body did not have a playground in the Tang Dynasty? That's fine.

"Liu Erlang, test its corrosion resistance and ductility." Yuan Tiangang put away the small flames, and said softly. The strange test is handed over to Liu Buzhun is right.

Yuan Tiangang's words dragged back Li Yuanying's thoughts that were drifting farther and farther away, and said a little tiredly: "Yuan Gong, you are busy, go back and rest for a while." ”

Yuan Tiangang looked at Xiao Ruoyuan and said, "You follow King Teng, don't let others disturb him, except for Princess Jinyang." Also, that lark is Wei Gong's apprentice, good at illusion, don't hurt him by mistake. ”

Xiao Ruoyuan put away the new number operation rules he was compiling, bowed his hand, and followed Li Yuanying out of the Hidden Sword Hall......
