For Professor Zhou, teaching at the university is certainly a relatively stable job, but this income is only that}

To be precise, he is only an associate professor, if he is in another university or fine, but in an unpopular university like the University of Geosciences, there is not much sweetness for an associate professor.

Fortunately, he himself is quite extroverted and travels widely, so he can make some extra money outside from time to time, but it doesn't have much money, and he is busy all year round, only about 100,000 yuan, counting the normal income in school, less than 500,000 yuan a year.

This income is not small if it is placed in second- and third-tier cities, but it is not enough in the imperial capital.

The wearing degree of an old snack can be removed more than half of this year, plus the four elderly people in the family have to support, and the money for medical treatment alone is not old or young a year, so there is not much surplus in the calculation.

At present, the two children in the family are going to college, and the tuition fee alone is more than 20,000 yuan a year, so he will take the initiative to bring students out to practice, because that is subsidized, although it is not much.

Now seeing the peculiarities shown by Zhao Sidong, he can't help but have a thought, or follow Dong Shao to make a fool of himself.

In his opinion, Zhao Sidong obviously needs a large number of jade mines discovered this time, and he just happens to be good at this area, why not use it? If he can get Dong Shao's reuse, the money is not the second, Dong Shao will definitely not treat himself badly, the point is, Dong Shao is the third generation of the old Zhao family, and it is obviously the kind that is very favored, climbed this big tree, hugged this thigh, and worried that there will be no good errand in the future?

Just as he was thinking about his future, Zhao Sidong suddenly asked, "Is it time to turn the corner in front of you?"

Professor Zhou looked up and couldn't help but be dumbfounded, he was supposed to walk for about half an hour, but he had already completed it in a few minutes, what kind of speed is this?

How did he know that this was still a situation where Zhao Sidong didn't know the way, otherwise it would have been estimated that he would have arrived at this time.

After calming down, he pointed to the side of the hill and said: "Dongshao, go around from that side, after walking about four or five hundred meters, you can see a big crooked neck tree, there is a mountain thorn bush under the tree, along its end and then to the northwest, along the valley all the way in, about seven or eight miles, you can see a small stream, go against the direction of the stream......"

Hearing him talk a lot, Zhao Sidong couldn't help but have a black line on his face.

"How did you find such a hidden place?"

To this question, Professor Zhou blushed and replied with a little embarrassment: "Actually...... We just wandered around without any goal, and then we stumbled upon it, only to get lost, and we almost couldn't get back. At that time, because of the strong magnetic field in the place where the vein was found, we thought that there was iron ore or something, but later it turned out that it was not. Fortunately, the people who participated in the field practice at that time were all students with good grades and flexible minds, otherwise, something might have happened. ”

After listening, Zhao Sidong was quite speechless.

Thinking of leaving a mark for the people behind him, he groaned a little, and saw a rock more than half a man high nearby, so he moved it over, and then used his fingers to carve a large word on it: from that side, after walking about four or five hundred meters, you can see a big crooked neck tree, under the tree there is a mountain thorn bush, along its end and then to the northwest, along the valley all the way in, about seven or eight miles, you can see a small stream, go against the direction of the stream......

In other words, he engraved the passage that Professor Zhou said just now, and gave a reminder at the end: take a picture with your mobile phone.

He has a super memory and can easily remember it, but others may not be able to remember it, so it is best to take a picture with his mobile phone so that he can check it at any time.

After doing all this, he took Professor Zhou, who was already stunned, and swept towards the direction of the vein with Zhang Ziyi.

This time, since they already knew the specific route, the two of them also raised the speed a little, which made Professor Zhou can't help but feel like he is driving through the clouds.

Moments later, the three of them landed in front of the door of a cave.

"Is this the place?" Zhao Sidong asked as he let go of Professor Zhou.

Professor Zhou forcibly stabilized his beating heart, and replied tremblingly, "No...... That's right, it's ...... It's this...... Here!"

Zhao Sidong glanced at him speechlessly, raised his hand and crossed a trace of Zhenyuan to help him straighten out his breath, "Okay, you wait for them here, if it's okay, it's best not to run around, just you, be careful not to have an accident." ”

Professor Zhou nodded, suddenly remembered something, and couldn't help but exclaim: "It's broken, I didn't bring the lighting tools!" Dong Shao, let's wait for them to come, bring all the tools and go in, it's very dark inside, if there is no light source, it is difficult to ensure safety!"

Zhao Sidong didn't accept his kindness, just smiled and said 'thank you', and then pulled Zhang Ziyi into the cave.

"Hey......" Professor Zhou opened his mouth to scream, but he couldn't see the shadow of the two of them, so he had to smack his lips helplessly, and said to himself: "Alas, okay, I hope you two are strong in kung fu and can have your own night vision function......

With that, he sat down on the stone by the side of the cave.

Zhao Sidong and Zhang Ziyi naturally do not have any night vision function, although with their current cultivation, they can indeed have the effect of night vision if they use their eyes, but ...... If you have illumination, why not use it?

After sweeping into the cave for a long time, Zhao Sidong took out an immortal crystal from the storage space, and after injecting a trace of true yuan into it, the immortal crystal lit up, emitting a white light, like an energy-saving light bulb, illuminating the cave transparently.

Throwing it into the air, the fairy crystal floated forward by itself.

The cave looks less like it was excavated by hand, but more like it was formed naturally after the earth's crust has changed, and the passage is tortuous and the walls are so intertwined that you can hit your head if you are not careful.

However, for Zhao Sidong and them, this kind of terrain is just pediatrics, and they regard it as a smooth road.

After going about three miles deeper, I saw the mineral deposits mentioned by Professor Zhou earlier.

The so-called ore deposit refers to the part of the earth's crust that is enriched with useful minerals or components, has met the industrial requirements in terms of quality and quantity, and has the conditions for mining.

Ore deposits contain ores, which refer to mineral aggregates from which useful elements, useful components or useful minerals cannot be extracted under current technical and economic conditions.

Ores often include two types of minerals: useful minerals and gangue minerals.

Useful minerals are minerals that provide useful elements or can be used directly in their own right, while gangue minerals are those minerals that are not useful in the ore.

With the development of technology and economy, whether a mineral aggregate can be used as an ore can be changed, and correspondingly, the concept of an ore deposit is also variable.

The amount of useful elements, useful components, or useful minerals in an ore is called grade.

The grade of metallic ores refers to the content of useful metallic elements or components in it, and the grade of non-metallic ores often refers to the content of useful minerals or useful components in it.

The rocks surrounding the deposit are called the surrounding rocks, while the rocks that provide a source of minerals in the deposit are called the parent rocks.

This knowledge was all brought out by Professor Zhou on the road before, and Zhao Sidong didn't care about the surrounding rock and mother rock, and after his divine sense swept in, he made sure that it was the kind of jade he needed, and then let out a long breath.

The results of the divine scan showed that this vein contained even more jade than the one obtained in Maine, and it was not a star and a half more, but a full number of times!

Zhao Sidong smiled happily, even the back molars were exposed, if someone looked into his mouth, he could even see the small tongue in his throat.

"It's mine!"

In addition to being excited, he suddenly stretched out his hand and hugged Zhang Ziyi into his arms, and shouted: "Ziyi, our luck this time is really good! With these jades, I am not afraid of having more people to take care of! Not to mention these families now, even if there are a few more, I can cover it!"

Zhang Ziyi's eyes fluttered in his arms, and he smiled charmingly: "What, do you want to come a few more?"

"Uh......" Zhao Sidong's laughter was sluggish, and he said embarrassedly: "I didn't mean that, I didn't think there was anything wrong before, but now that the Sanqingguan incident has happened, I realized that before my strength reaches the level where I can ignore any enemy, I am really asking for trouble for myself." So I've decided that I can't show mercy everywhere like I used to in the future......"

Zhang Ziyi suddenly interrupted him and asked, "What if people don't have families and are orphans?"

"Of course...... Ahem, of course, it can't have anything to do with it!" Zhao Sidong, who was almost out of his mouth, said with a straight face: "You must know that people's energy is always limited, and there are so many women now, and it is impossible for me to give up any of them before ascending in the future, so I will definitely spend a lot of time and energy to help them improve their cultivation in the future." With you, I can save some energy, but if there are a few more, I'm afraid I won't be able to take care of it. ”

Zhang Ziyi punched him funny, "Okay, okay, don't be duplicitous, don't think I don't know, with your ability, as long as you reach the Merge Dao period, you can refine the Taixu Dynasty Immortal Pill." At that time, as long as they take this pill, they will be able to raise their cultivation to the stage of merger in a very short period of time, and then with the double cultivation method, they can easily take them to the final level together...... Am I right?"

Seeing that his hole cards were pierced, Zhao Sidong didn't show an embarrassed expression anymore, but smiled calmly: "That being said, but the problem is that with such a thin aura on the earth now, even if I have the help of the Spirit Gathering Array, I don't know how long it will take to break through to the Merge Period!"

"Not necessarily, as long as the matter of the Great Array is resolved, you can completely use those immortal crystals to cultivate!" Zhang Ziyi said unexpectedly.

For her idea, Zhao Sidong replied lightly.
