Train Survival: I Know My Luck

This kind of lens is only available in Yu Qian'an. Yu Qian'an can make green ones. When Yu Qian'an bought it, he thought he would not use it for a long time, but he used it in a few days.

In addition to the lens, the headlight also needs steel ingot x2, tin x1, tungsten x1, glass x1, copper x1, plastic x1, and parts x1.

It feels like a lot of materials are wasted when making this thing. For example, tungsten is used for a filament, but why do you need one? And tin, plastic, and copper are all wasted for the most part.

Yu Qian'an calculated that there are two on the front of the car, two on the rear, two on each side of the car, and one on the top of the armored train, so at least seven are needed.

When choosing the manufacturing quantity, Yu Qian'an found that the demand for tin, tungsten, copper, and plastic parts did not increase with the increase in manufacturing quantity. One headlight is needed to make one, and ten headlights are also only needed to make one. For tungsten, it only takes one hundred headlights.

Yu Qian'an felt that he had lost a lot. Why didn't he try mass production when making fill lights!

Among these materials, tungsten is the most scarce resource. Yu Qian'an naturally made a hundred headlights in one go based on the principle of not wasting tungsten ore. Anyway, it would be easy to sell if they were not used up.

After the hundred headlights were made, Yu Qian'an first sent a message on the public channel: "Are you still worried about driving in the dark at night? Are you still worried about being attacked by monsters at night? Now I sell train headlights, green quality, which can be installed in the front, back, left and right of the car. One more headlight means more safety. The quantity is limited, first come first served!"

Regardless of the message, Yu Qian'an sent a message to each of the three major customers: "Do you want headlights? New assistant for night driving."

Yao Yong: "Yes, I want seven. How to exchange?"

Yu Qian'an: "One headlight requires one tungsten ore plus four green materials."

Yao Yong: "I only have three pieces of tungsten ore. Can I use other materials instead?"

Yu Qian'an was happy, and knew that these guys must have kept a trick up their sleeves. They all had tungsten ore but didn't exchange it with me!

Yu Qi'an acted helpless: "Okay, we are old friends. If there is no tungsten, I will exchange it for ten green materials. Three tungsten ores plus 52 green materials will give you seven headlights."

Although Yao Yong felt a little distressed, he had to take out the materials to exchange when he thought of the usefulness of the headlights.

Then it was Liu Jun. After Yu Qi'an sent the information about the headlights, Liu Jun sent a message: "Brother Yu Qi'an, I will gather some here, wait for me for a few minutes."

A few minutes later, Liu Jun replied: "Brother Yu Qi'an, we only have ten tungsten ores, but we want to buy more headlights. Do you think we can use other materials instead?"

Yu Qi'an: "If there is tungsten ore, it is one tungsten ore plus four green materials. If there is no tungsten ore, it is ten green materials."

Liu Jun: "Okay, I will buy fifty headlights first, ten tungsten ores plus four hundred and forty green materials, right? Let's trade."

Yu Qi'an was stunned for a moment. Doesn't this person bargain? Soldiers are indeed straightforward. Can retail and wholesale be the same?

However, Yu Qian'an did not intend to offer a discount. Knowing how to save tungsten ore, Yu Qian'an made another fifty sets of fill lights in one breath and gave one set to Liu Jun: "You bought so many, so I'll give you a set of fill lights. This can speed up the growth of plants."

Liu Jun: "Thank you!"

Finally, it was Yang Jiarui: "Yang Fuxing, do you want a headlight? As long as you ask, I will send it to you immediately?"

Yang Jiarui: "Yes, you can send it."

Yu Qian'an: "Okay, I'll give you a friendly price. One tungsten ore plus four green ores will give you one headlight."

Yang Jiarui: "Does it mean that if there is no tungsten ore, you need ten green materials?"

Yu Qian'an: "How did you know?"

Yang Jiarui: "What do you think? I'm trading cherry tomatoes with Yao Yong! You are such a profiteer!"

Yu Qian'an: "What you said, I didn't raise the price randomly, is it the same?"

Yang Jiarui: "I want to buy ten and give you ten cherry tomatoes. Do you want to exchange?"

Yu Qian'an: "No OK, it's a little too little, I can't eat cherry tomatoes. And how can one cherry tomato be worth ten green materials? "

Yang Jiarui: "Add two more green melons!"

Yu Qian'an: "Add five, no, the ones I planted are not ripe yet, how come another wave is ripe?"

Yang Jiarui: "You are too mean, I will take it... at most three!"

Yu Qian'an thought for a while: "Five! You are so lucky, you must have more than one seed at a time, and a vine can't just take one melon!"

Yang Jiarui: "I am guilty of being lucky, should I be ripped off by you?"

Yu Qian'an: "Then I will take three less cherry tomatoes, okay!"

Yang Jiarui: "Five cherry tomatoes and five melons!"

Yu Qian'an: "Deal!"

After exchanging for five cherry tomatoes and five melons, Yu Qian'an washed them and ate them directly. The melons were not as refreshing as the blue ones, but they tasted very good. After eating, Yu Qian'an's strength reached 22, his physique reached 23, and his agility also increased a little to 18.

Open the trading channel, there are a lot of private messages, the most conspicuous is the friend message, click on it and it is from Le Xing: "I also need headlights, how to change?"

Yu Qian'an sent a message to Le Xing: "What is your current physical value?"

Le Xing: "Strength 18, Constitution 16, Agility 19. What's wrong?"

Yu Qian'an: "Do you have any good stuff?"

Le Xing: "No more!"

Yu Qian'an: "That's a shame. I just got a green melon. I guess your strength and agility can soar to 20 after eating it."

Le Xing: "..."

After waiting for a while, Le Xing sent a message: "I have another good thing, but one green fruit is definitely not enough for you! Even ten are not enough!"

Yu Qian'an raised his eyebrows: "Tell me, if you have a good thing, I still have blue fruit, which can increase your stats by more than ten points at a time!"

Le Xing: "I practice a family Qigong. I used to think it can strengthen my body, but after entering the game, I transformed a new attribute of internal force. I asked other people, and they didn't have it!"

Yu Qian'an: "Take a photo for me to see!"

Le Xing: "Okay!"

Le Xing's photo came over, and Yu Qian'an saw:

Le Xing

Strength: 18

Constitution: 16

Agility: 19

Internal force: 8

Spirit: 11

Health: 100%

Luck:?

He really has more internal strength than himself. Yu Qian'an hurriedly went to check on the melons he planted, and came back to send a message to Le Xing: "My melons will be ripe tonight or tomorrow morning. Let's exchange them then!"

Le Xing: "There is no paper or pen here, so I just dictate it to you?"

Yu Qian'an: "I have paper and pen, wait a minute, I will make one for you, and you write it in detail later, so that I don't get a stitch in the side when I practice."
