Chapter 720： Oil (three shifts)

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. The 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 at that time were deeply in love with me."

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

After thinking for a moment, Xiao Jingrui shouted, "Someone, go and get oil for this palace."

By oil, of course, he refers to all kinds of oil, such as lamp oil, animal oil, etc., which are all 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 drawings, Xiao Jingrui and his party will definitely be walking here. And, if I'm not wrong in my estimation, he may be there every time he arrives. At the sign, people will definitely detect whether 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."

For ordinary people, it is difficult 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 thought for a moment and said, "If this is the case, then we will definitely arrive first according to the markings on the drawings. However," he asked suspiciously, "Yue'er, they don't have that metal detector with a mother in their hands. 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 I'm not wrong. Mother's metal detector is probably out of oil! A metal detector without oil is a piece of waste. Besides, even if there is oil, they will not Will be used!"

Jiang Zhennan was curious now.

He asked, "Is that stuff going to be oiled? What oil are you going 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 bulky. Personal force, this kind of detector, the oil that needs to be added is a kind of gasoline and oil.

The heat generated by burning this gasoline can drive the gears of the machine to run, which is convenient for exercise.

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 knowingly, 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 in two thousand years is really amazing! It is possible to invent so many unheard and unseen things!"

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

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

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

Lin Yuelan replied, "A car that runs on the ground is like a horse-drawn carriage today. However, at that time, the horse-drawn carriage was not driven by horses, but walked on wheels. Submarines that swim in the water were human beings that could swim in deep water like fish. The river bottom of dozens of meters is free to move, and as for flying in the sky, that 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 are also severely revengeful from nature.

Earthquakes, tsunamis, floods, acid rain, etc. have eroded 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 turn into 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 times.

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 completely killed by her best friend and her boyfriend.

After traveling here, although she always warned herself not to trust others, but she couldn't bear it in her heart, prompting 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 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 and listened 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 couldn't actually blame anyone, she could only blame herself for not knowing people well and being blind.

Therefore, it will be used by people 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.

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

Therefore, from every step she crossed over, she was looking at people with her heart, and then she saw these people who treated her with sincerity, and those who she also wanted to treat with sincerity.

"Uh-huh……"

Just when the two were quiet, a cough came from outside the window.

The two looked around and saw that it was Liu Yichen standing by the window.

At this moment, he was looking at them with half-smiley eyes, and then deliberately said to Jiang Zhennan, "General Jiang, although you are a fiancée couple, but after all, you are not married yet. You still have to pay attention to how you hug me. It's a good occasion."

Having said that, he deliberately looked at Lin Yuelan again, and scolded in the tone of an elder brother, "Sister, you are not married yet, so let him take advantage of it. What if you suffer in the future? So, for the sake of the future, you should give less. He took advantage, you know?"

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

He said angrily to Liu Yichen, "Eldest son Liu, haven't you heard that disturbing someone's relationship is going to be a thunderbolt?"

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

Jiang Zhennan, "..."

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

Whatever he said, he would respond.

Lin Yuelan was suddenly 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 and looked sad. He said with a sullen and aggrieved voice, "Sister, does the eldest brother have to have something to find you?"

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

After a moment, Jiang Zhennan waved to Liu Yichen and said, "Okay, you are disgusting or not. It's enough for a big man to act like Xi Shi holding his heart."

Listening to Jiang Zhennan's disgust, Liu Yichen immediately returned to normal. He said angrily to Jiang Zhennan, "I didn't do anything to you, you are disgusting."

Then, he turned to Lin Yuelan and asked, "Sister, are you looking for something when you came out this time? And I just overheard what you said about a metal detector. Is there really such a tool?"

Jiang Zhennan's face suddenly became cold and severe, and he said coldly to Liu Yichen, "Master Liu, didn't you say that you came out for a tour? Why are you asking so much?"

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

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

But then she looked at Liu Yichen and smiled and said, "Big brother, it's not my sister, I'm guarding you. But this time, Big Brother Nan and I are on a secret mission with Your Majesty. This mission must be kept secret from everyone. So, Shu Xiaomei can't tell eldest brother!"

This time Liu Yichen was really surprised.

He had guessed that Lin Yuelan and Jiang Zhennan suddenly said that they were going to go out for a sightseeing tour. They must have 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 deepness and seriousness, and then they told everyone to go out.

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

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

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

Along the way, although he released his inner strength and wanted to eavesdrop on their conversations, both Jiang Zhennan and Lin Yuelan were both highly skilled 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 in his heart.

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 was still wary of him.

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

He admitted that he had a certain purpose in approaching Lin Yuelan at the beginning, in order to explore Lin Yuelan's secrets.

However, the deeper he got in touch with Lin Yuelan, the more interested he became.

But at the same time, he felt distressed and angry about what happened to Lin Yuelan before, and then, slowly, he really regarded Lin Yuelan as his own sister.

The charming heart at the beginning has turned into the ties of family affection. Such a change is surprising even to him.

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

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

But at this moment, he suddenly realized that the sister he wanted to protect had been guarding against him from the very beginning.

All of a sudden, let him not know what to do?

Overwhelmed!
