Youyou was sent home, and her heart was a lot more steady, and she was about to wash when she heard a knock on the door.

"Tang Youyou, are you going to find Li Junshuo again?" Qilin looked dissatisfied and stood at the door angrily.

Yu Yu didn't answer him, leaned against the door tiredly, she was tired, she had been very tired lately, she always wanted to sleep, but she never had a chance to sleep well.

"Tang Youyou, I'll talk to you!" Qilin shouted.

Yu Yu came back to his senses, "What's the matter?"

Qilin is really helpless, "Uncle Han said let us go over now and help record the data." ”

"Ahh Yu Yu said resistantly.

"It's only half past eight now, Tang Youyou, what time did you get off work before? Kirin said indignantly.

The two went downstairs together, and since they met Huang Mao, Huang Mao lent a motorcycle to Kirin.

Kirin and Yuyou put on their helmets and rush to the bar together. (It's the original bar, and now the exhibition hall is under construction, so it will be called the exhibition hall in the future.) ）

The two received Han Xiao's notice and went directly to the second floor underground.

After two days of hard work, Han Xiao had already asked Huang Mao and them to tear down the walls, and now it was the same as the first floor on the ground, it was also an empty hall, and in the center of the hall, there was a tripod with a camera-like thing, and a person was standing and fiddling.

Another person crouched on the ground, opening a large suitcase.

They walked over, and the trunk was a pushing instrument and a small computer screen.

Han Xiao and Zheng Ruan Hao approached from a distance and greeted Qilin and Youyou.

"Uncle, what are we doing?" Qilin asked.

Han Xiao smiled mysteriously, "You don't have to do anything, just stand there honestly, I'm superstitious now, I'm afraid that my aura is not enough, find two more people who are sincere to me, maybe I can measure good things." ”

Qilin's eyes widened curiously, he looked at the instrument again, then at Han Xiao, and said excitedly, "What is the gold mine down there?"

Hahaha...... Zheng Nguyen Hao burst out laughing.

Han Xiao patted Qilin's head and said with a smile: "Silly boy, you know how to make money, we are here in the plains, and we have to go to the mountains to find the gold mine." ”

"What if there's gold buried underneath, didn't you say it was an ancient tomb!" added Kirin, scratching his head.

Han Xiao never thought about what would appear below, just inferred that it might be empty below, which already made him very excited, in fact, he didn't expect anything to really be below, he just didn't want to stop exploring and searching.

"Kirin, when you graduate in the future, I will hire you to work in our company with a high salary. Zheng Ruanhao on the side said with a smile.

"I'm going to be a police officer, not going to you. Kirin replied.

Han Xiao glanced at Zheng Ruanhao with disdain, and came to him to dig a corner of the wall, not to measure himself.

Zheng Ruanhao looked at the surveyors boringly, he really couldn't get any good here, and the geological surveyors he invited didn't give some benefits, even if he didn't give some benefits, he always gave his face.

Surveyors have already started to measure.

After a while, some paper was punched out of the big box on the ground, and the person squatting on the ground tore it off and handed it to Zheng Ruanhao.

Zheng Ruanhao took it, well, he couldn't understand it either, he scratched his chin with his finger and asked, "Is there something down there?"

"It's similar to a normal surface layer, it's low in rare metals, but it'......," the man frowned.

"Is there anything else?" Han Xiao asked, his tone a little hurried.

The man nodded, "Our main metal measuring instrument, if the metal content is too low, the measurement results will not be ideal, you can find the original archaeological excavators, after all, they are more professional." ”

As soon as he finished speaking, he and his accomplices packed up their equipment.

"Don't you need to test again?" Han Xiao asked.

The man shook his head and smiled: "It's been measured twice, and the results we get after calibration can't be wrong." ”

Zheng Ruanhao hurriedly called the assistant and drove the car to send the staff back.

Youyou took the note from Han Xiao's hand and read it with Qilin.

"Kirin, do you remember this symbol?" said Youyou, pointing to the letters on the paper.

"Jin!" Qilin said confidently, it was too easy to test him, "Is there anything else?" ”

"So, what about this?"

"That's platinum, both of which are on the periodic table, and you asked me to memorize it. Haha, I see that my level is still very high. Kirin smiled smugly.

Yu Yu frowned.

Han Xiao on the side noticed the conversation between the two and looked at Youyou.

"In fact, in our lives, gold, silver and other trace elements, there is no loess, but there is sand and gravel, the early buildings are mainly loess and hay, so the metal content is minimal, but later the introduction of sand and gravel, some metal elements such as gold and silver are also brought in. ”

"That is, the house we live in has gold?" Qilin's eyes lit up when he heard this.

"Not all, because the amount is too small, it's not worth refining. But there is one metal that is rarer than gold. Yu Yu continued.

"I know, it's platinum. It is one-thirtieth of the gold reserves. Kirin replied.

Youyou smiled, "But the data just now shows that the platinum content here is much higher than that of gold and silver, and under normal circumstances, platinum is the associated mineral." ”

"We are mainly plains here, which means that there is a building layer underneath, and it is very likely that it is a specially built building layer. Youyou racked her brains and tried to be as clear and professional as possible.

When Han Xiao heard this, his heart was overjoyed, and he knew that these two children were his lucky stars.

He smiled happily: "It seems that I didn't measure in vain today, and I didn't invite the two of you to come over in vain, and tomorrow one person will have a big red envelope, which is considered today's overtime pay." ”

The unicorn jumped high with joy.

Yuyu smiled happily too.

Zheng Ruan Hao was surprised by the amount of knowledge in Youyu, he always thought she was a beautiful little girl, but he didn't expect that he knew so much and could still use it in key places, so he had to look at her again.

Suddenly, his head was hit hard, he retracted his gaze and glared at Han Xiao: "Don't hit me on the head, how many times have I told you." ”

"I'm just reminding you that you have a wife, and people don't like you. Han Xiao said without giving face.

"Heck, I just think Youyu is more talented, nothing else. Zheng Ruan Hao really convinced him.

"Well, I'm going to tell you in advance that the two of them will be my people in the future, and you won't beat their ideas. Han Xiao warned.

Zheng Ruanhao touched his head and looked aggrieved, "When did I beat their idea!"

Han Xiao smiled without saying a word, looked at them who ran into the distance to find their original location, and suddenly found that they were old, and the world was really theirs.
