Chapter 146 Quiz

Since practicing mental strength, Gu Lie's memory is amazing, and he can see almost everything once. Roger in the image introduced hundreds of known ores in an hour, including names, characteristics, uses, etc., and he remembered them all.

When Roger finished explaining the last kind of ore, the light curtain disappeared in the air, and Gu Lie couldn't help stretching out.

"Have you finished reading it?"

Gu Lie nodded his head and said, "After reading it, I didn't expect that there were so many kinds of ores. It's really difficult to remember after thinking about it."

Roger snorted coldly, "You have to be down-to-earth step by step. It took me more than ten years to summarize this knowledge. You actually want to remember it in an hour. It's really whimsic!" He is quite confident in his level.

Gu Lie nodded with a smile and did not refute.

Roger has a proud capital. Whether it is the accumulation of mechanical knowledge or age experience, he is much better than Gu Lie. Such a person is most suitable to be a mentor and guide. There is no need for Gu Lie to anger him at all. He is used to being high-key in Nile Town, and it is difficult to keep a low profile. Only in front of Roger can he enjoy the comfort brought by low-key, which will relax his tense nerves a little.

"Ok, now you can choose ten kinds of ores with your memory. The difference is not a success. If you fail, you have to read the book again!" Roger is completely in a working state, like a rigorous teacher.

Gu Lie came to the ore pile, took a pair of gloves from the side, and then grabbed a piece of ore and looked at it.

This ore is only the size of a football, but it is very heavy in the hand, weighing more than ten catties. The surface is full of honeycomb eyes, which is a black-green color.

This is meteorite copper ore, which is a very rare ore formed after the collision between an external meteorite and an underground copper ore. The price is extremely high, and it is not easy to refine metals. Only a senior mechanic like Roger will do this kind of thing.

meteorite copper ore is very rare and very easy to identify. After all, its characteristics are too obvious.

Gu Lie weighed the weight in his hand, grinned and said, "This is meteorite copper ore."

Roger looked at him coldly and shouted, "If you can't recognize such an easily identified ore, you can just jump off the building. What's so complacent? The next piece!"

Gu Lie shouted in his heart, "It's so fucking panicked!" I didn't expect that once Roger entered the state, he would be so strict. He was simply an old-fashioned old man who didn't recognize him. Compared with just now, he was completely two people, and even gave Gu Lie the illusion that he was divided.

While thinking about this, Gu Lie put the meteorite copper ore aside and picked up a piece of polygonal ore of the same football size but irregular shape.

The black surface is very rough, which feels a little like "coarse sandpaper". The weight is moderate, and it can weigh about five or six catties. The junction of the polygon is relatively sharp. If you don't wear gloves, it is easy to scratch the skin.

"This is a grain ore!" Gu Lie said without looking back.

This kind of ore is used to make glass. Due to the different molecular composition, there is no need to strengthen it too much. The glass is very hard. At the same time, there are some toughness of tempered glass, which will not be broken easily.

"Next!" Roger's face was expressionless, and it seemed that he was not surprised that Gu Lie guessed two in a row.

Gu Lie shook his head helplessly, looking for the next ore.

"Sink iron ore..."

"Lingshi Mine..."

"cobalt ore..."

Gu Lie guessed nine ores in a row, and Roger showed a little gratified look on his face. However, at this time, he was staring nervously at Gu Lie, holding the tenth ore in his hand. If he can guess correctly this time, it can be completely described as a genius.

Roger has been in the industry for so many years. Since he summarized the ore classification, the people he has taught have not been able to guess at once. Even if he picks the simplest and easiest ore to identify, he can't do it.

If Gu Lie does it this time, he will really pick up the treasure. As long as he knows enough about ore, it will become very easy to refine alloys. Even the metal cutting and production that need to be learned later will become easy to learn.

In a word, in all scientific systems, basic knowledge is the most important.

Gu Lie looked sadly at the ore in his hand, which was so ordinary that it could not be ordinary. Even if he called the ore countless times in his heart, he just didn't say it.

He glanced at Roger's nervous look with his spare light, which made him find more or less face. In this way, Roger still appreciated and valued himself very much, otherwise he would not be so nervous when he got stuck in the last ore. Before that, he was expressionless and shouted loudly.

"This is..." Gu Lie hesitated and didn't say anything. Seeing Roger's anxious appearance, he didn't know how happy he was.

Seeing that he didn't say it, Roger was also relieved and whispered, "If you are not sure, it's better not to speak rashly. Carefully observe the appearance and feel the weight. Every ore has something special. It depends on whether you can find it." He is surprisingly patient.

Gu Lie nodded, tilted his head for a long time, and finally decided to say the answer.

In fact, this ore is not difficult to guess. Although it is not as rare as the meteorite copper mine, it is because it is too ordinary, but it is easy to be ignored. In addition, he has just finished reading the introduction of hundreds of ores. If he can call out the name of the ore with his mouth, it is really too ostentatious.

"Zirconium silver ore!" After Gu Lie finished speaking, he turned his head and looked at Roger, as if he was asking if he had answered correctly.

Roger took a deep breath, smiled at him, and put his hand on his forehead. It turned out to be a layer of sweat. Just now, he was worried enough. Fortunately, Gu Lie answered correctly.

"You are a genius, a real mechanical genius!" Roger did not hide his appreciation for Gu Lie and sighed, "Over the years, you have been the only one who has passed the test once, and you can only be described by genius!"

Gu Lie said modestly, "It can only be said that you are lucky. What you find is relatively easy to identify ore."

Roger shook his head and said unwillfully, "I said you are a genius!" Luck, is luck useless? You have to remember the names and characteristics of hundreds of ores in an hour. Not to mention the characteristics of the ores, it's good to remember all the names, and you can recognize them smoothly. There are very few such people.

At this point, Roger smiled again and said to Gu Lie patiently, "A long time ago, there was a saying that 'humble makes people progress, pride makes people retreat'. At first glance, it is right, but now it doesn't work. You should understand that excessive modesty is pride, which will give people a sense of arrogance and even anger all powerful people. At any time, not being modest and arrogant is the best choice!"
