Jiang Yunfeng nodded and said, "Yes. She said that this thing needs oil."

    Xiao Jingrui stroked the metal detector again and asked in confusion, "If you need oil, how is the oil used? Where is it used?"

    Jiang Yunfeng shook his head and said, "I don't know. That woman didn't tell me clearly."

    When he said this, his eyes flashed with a guilty conscience.

    Xiao Jingrui said sharply with obvious sarcasm, "It's because she didn't say it clearly, or you didn't hear it clearly! As far as I know, you and Wen Yujing were deeply in love with me at that time. already."

    Jiang Yunfeng couldn't refute, he could only smile shyly.

     

    By oil, of course, he refers to all kinds of oil, lamp oil, animal oil and other things that are related to oil.

    "Yes, Your Highness!" The subordinate immediately fled after obeying the order.

    …

    On the other side, Lin Yuelan took out the blueprints, pointed to a mark and said, "If Jiang Yunfeng can copy these blueprints, Xiao Jingrui and his party must be walking here. Moreover, if I am not wrong in my estimation If he does, he may have someone detect every time he goes to a sign to see if there is gold or iron."

    Jiang Zhennan looked at Lin Yuelan pointing to Yishan in the map, and said slightly puzzled, "So, there must be people in this area around them."

    It is difficult for ordinary people to know whether there is gold or iron in this place.

    But for professionals, they have their own expertise to verify.

    Lin Yuelan nodded and said, "It's very possible. So, every time they go, they may stay for a while to test these places!"

    Jiang Zhennan immediately thought about it and said, "If this is the case, then we will definitely arrive first according to the markings on the drawing. However," he asked suspiciously, "Yue'er, in their hands Isn't that the metal detector of your mother? Will they use this metal detector to quickly detect whether there is gold and iron ore in there?"

    Lin Yuelan shook her head and said, "If my guess is not wrong. Mother's metal detector is probably out of oil! A metal detector without oil is equivalent to a piece of waste. Let's talk about it. , even if there is oil, they won't use it!"

    Jiang Zhennan is curious now.

    He asked, "Is that thing oiled? What oil to use?"

    Lin Yuelan explained, "In our time, metal detectors can be divided into large detectors and small detectors. Large metal detectors are generally purchased by metal development companies. Such machines are particularly complex and It is bulky and requires several people to use it. The oil that needs to be added to this detector is a kind of gasoline and oil.

   

    Oil is lubricating.

    The biggest advantage of this large metal detector is that it is accurate and there are few mistakes.

    As for small metal detectors, they are generally used by geological surveyors of the Institute of Geology because they are easy to carry. According to the relics from the mother, it can be guessed that the mother may be a geological surveyor. Naturally, the metal detector she brought out was a small one.

    However, the accuracy of this small detector is not as high as that of a large metal detector. "

    Jiang Zhennan nodded in understanding, and then he asked, "What kind of oil is needed for such a small metal detector?"

    Lin Yuelan smiled and shook her head, "It can be oil or gasoline. You can also use batteries."

    Jiang Zhennan didn't understand what Lin Yuelan said at all.

    He said very curiously and yearningly, "The world two thousand years later is really amazing! It is possible to invent so many unheard and unseen things!"

    Lin Yuelan said with a wry smile, "Yeah. The world two thousand years later will be wonderful, all the unimaginable things, the world after two thousand years, can create anything. For example, running on the ground. Cars, submarines swimming in the water, planes flying in the sky, there are really only things you can't think of, nothing you can't see! It's just,"

    Lin Yuelan's eyes flashed a look of sadness, and then continued, "It's just that the world was over-exploited and polluted because of nature, and then it was revenge by nature, and the result became the end of the world for mankind. "

    Jiang Zhennan pondered for a moment and asked, "What are the cars running on the ground, the submarines swimming in the water, the planes flying in the sky? And what does the end of the world mean? ?"

    Lin Yuelan replied, "The cars running on the ground are like the carriages of today. However, at that time, the carriages were not driven by horses, but walked on wheels, and submarines swimming in water were Humans can move freely on the bottom of the river dozens of meters deep like fish, and as for flying in the sky, it means that humans can fly in the sky. They can even fly to the moon.”

    Jiang Zhennan heard Lin Yuelan say that this human can actually fly to the moon, and glanced at the bright moon hanging in the sky, his eyes were full of shock.

    "It's just a pity that while human beings enjoy excessively, they also suffer strong revenge from nature.

    Earthquakes, tsunamis, floods, acid rain, etc. are eroding the environment in which human beings live, one after another, and revenge all disasters on human beings.

    In the end, it evolved to the point where people become zombies and people eat people. If you are not strong, then you are only to the point of being eaten or played with. "

    Although Lin Yuelan still has some nostalgia for the past, what she misses is the happy times when she was a child and at work.

    As for the last few years, let her be an ordinary white-collar worker and become a small leader of a base.

    But the end times are cruel and ruthless.

    There is no blood, let alone humanity, the only thing is to live.

    Humans kill each other for a piece of bread.

    In order to preserve their strength, the old and the weak may be killed in an instant.

    This is the end time.

    It's just that even though Lin Yuelan is a power user and a strong person, she still retains the kindness in her heart.

    But her kindness was killed by her best friend and her boyfriend.

    Traveling here, although she always warned herself not to trust others, but she couldn't bear it in her heart, which prompted her to learn to trust again.

    But she still adheres to the principle that people do not offend me, and I do not offend others.

    Jiang Zhennan looked at Lin Yuelan's expression. Although she didn't know what she was thinking now, she could still guess that it must be something bad happened to her in the last days.

    Jiang Zhennan gently hugged Lin Yuelan and comforted, "Yue'er, everything is over. Let's stop thinking about it, okay? I don't want you to be unhappy!"

    Lin Yuelan leaned against Jiang Zhennan's arms, listening to his "thump-thump" beating heart, at this moment, she felt very peaceful.

    Although the pair of scumbags failed her and made her heart full of holes, but she can't really blame anyone, she can only blame herself for not knowing people , eyes blind.

    That's why they are used and betrayed by them.

    However, after coming to this world, she also understands that there are many ruthless and unrighteous people, but there are also sentient and righteous people.

    She has to look at it with her own heart, instead of blindly looking at the surface.

    So, from every step she passed through, she was looking at people with her heart, and then she saw these people who treated her with sincerity, and those who she would also treat with sincerity.

    "Hmmmmmmmmm"

    Just as the two of them were quiet, a coughing sound came from outside the window.

    The two looked at each other and saw Liu Yichen standing by the window.

    At this moment, he was looking at them with a half-smile but not a smile, and then deliberately said to Jiang Zhennan, "General Jiang, although you are a fiancée couple, but after all, you are not married yet. I hold my posture, you still have to pay attention to the occasion."

    Here, he deliberately looked at Lin Yuelan again, and scolded in the tone of the elder brother, "Sister, you are not married yet, so let him take advantage, what if you suffer in the future? So, For the sake of the future, you should not let him take advantage of it, you know?"

    Lin Yuelan's face turned slightly red, while Jiang Zhennan's face was covered with black lines.

    He said to Liu Yichen angrily, "Liu Da Gongzi, haven't you heard that disturbing people's love is going to be struck by lightning?"

    Liu Yichen retorted sharply, "Oh, is that so? That young man will just wait for the thunder to strike!"

    Jiang Zhennan, "…"

    This Liu Yichen's face is really getting thicker and thicker.

    However he refutes.

    Lin Yuelan was speechless.

    However, she didn't want to see the two continue to fight each other so naively.

    Immediately, she asked, "Brother, are you okay?"

    Liu Yichen immediately covered his chest, making a sad expression, he said with anger and grievance, "Sister, does eldest brother have to have something to find you?"

    Jiang Zhennan and Lin Yuelan had black lines on their faces and were instantly speechless.

    For a moment, Jiang Zhennan waved to Liu Yichen and said, "Okay, you're disgusting, aren't you. It's enough for a big man to act like a Xi Shi and hold his heart."

    Listening to Jiang Zhennan's dislike, Liu Yichen immediately returned to normal, he said angrily to Jiang Zhennan, "I didn't do it to you, you are disgusting."

    Then, he turned to Lin Yuelan and asked, "Sister, are you looking for something this time? And I just overheard what you said about metal detectors. It really is like this. utensils?"

    Jiang Zhennan's face suddenly became cold and stern, and he said coldly to Liu Yichen, "Master Liu, didn't you say that you came out to visit the mountains and waters? Why are you asking so much?"

    Liu Yichen ignored Jiang Zhennan's cold face, but looked at Lin Yuelan with a very serious expression, and then asked with a sad look, "Or sister, you have always been Are you guarding my brother?"

    When Liu Yichen asked this, Lin Yuelan was stunned for a moment.

    But then she looked at Liu Yichen and smiled and said, "Brother, it's not my sister, I'm guarding you. But this time, Brother Nan and I are on a secret mission with Your Majesty. Everyone must keep it a secret. So, little sister Shu can't tell big brother!"

    Liu Yichen was really surprised this time.

    He had guessed that Lin Yuelan and Jiang Zhennan suddenly said that they were going to go out for a sightseeing tour. There must be some purpose, and it was even possible that it was a mission given by the emperor.

    After all, after they came out of the palace, their expressions were a little different, with a deep and serious look, and then they told everyone to go out.

    So, this is very reminiscent of the task given by the emperor.

    He was sidelined, and neither of them told him the truth.

    There is no other way, he can only follow the two of them shamelessly to see if he can find any news.

    On the way, although he released his inner strength and wanted to eavesdrop on their conversation, both Jiang Zhennan and Lin Yuelan were both strong in martial arts.

    Since the two were prepared to guard against him, they naturally wouldn't let him hear the key news.

    Thinking of this, Liu Yichen sighed.

    For some reason, he always felt that Lin Yuelan didn't seem to trust him.

    Even if they were siblings, even if they were business partners, even if they were happy.

    But Lin Yuelan is still wary of him.

    To be honest, Liu Yichen is really sad at this moment.

    He admitted that he approached Lin Yuelan with a certain purpose at first, in order to explore Lin Yuelan's secrets.

    However, the deeper the contact with Lin Yuelan, the more interested he became.

    But at the same time, he felt distressed and angry about Lin Yuelan's previous experience, and then, slowly, he really regarded Lin Yuelan as his own sister.

    The charming heart at the beginning turned into the ties of family affection. This kind of change surprised even him.

    But at the same time, he was very sure in his heart that he would not hurt Lin Yuelan whether it was the ambiguity of my friendship or the ties of my family.

    He wants to protect Lin Yuelan, this sister who is not a sister!

    But at this moment, he suddenly realized that the sister he wanted to protect was guarding him from the beginning.

    This time, he didn't know what to do?

    Overwhelmed!
