This kind of lens is only available from Yu Qian'an, and he can make green ones. When Yu Qian'an bought it, he thought he would not use it for a long time, but he did not expect to use it in just a few days.
In addition to the lens, making a headlight also requires Steel Ingot x2, Tin x1, Tungsten x1, Glass x1, Copper x1, Plastic x1, and Parts x1.
It feels like a lot of materials were wasted in making this thing, like the tungsten, which is only used for the filament, but why bother with that? Also, most of the tin, plastic, and copper were wasted.
Yu Qian'an calculated that there would be two at the front of the train, two at the rear, two on each side of the train, and one on the top of the armored train, so at least seven would be needed.
When choosing the manufacturing quantity, Yu Qian'an discovered that the demand for tin, tungsten, copper, and plastic parts did not increase with the increase in manufacturing quantity. One part was needed to make one headlight, and only one part was needed to make ten headlights. For tungsten, only one part was needed to make one hundred headlights.
Yu Qian'an felt that he had suffered a great loss. Why didn't he try mass production when he manufactured the fill light?
Among these materials, tungsten is the most scarce resource. Yu Qian'an naturally followed the principle of not wasting tungsten ore and made 100 headlights in one go. Anyway, if they were not used up, they could be sold.
After the hundred headlights were completed, Yu Qian'an posted a message on the public channel: "Still worried about driving in the dark at night? Still afraid of being attacked by monsters at night? Now I'm selling train headlights. They are green quality and can be installed on the front, back, left, and right sides of the train. One more headlight means one more point of safety. Quantities are limited, first come, first served!"
Regardless of the message being sent, Yu Qian'an sent a message to each of his three major customers: "Do you want headlights? A new assistant for night driving."
Yao Yong: "Yes, I need seven. How do I exchange them?"
Yu Qian'an: "One headlight requires one tungsten ore and four green materials."
Yao Yong: "I only have three pieces of tungsten ore. Can I use other materials instead?"
Yu Qi was happy, because he knew that these guys must have kept something back. They all had tungsten ore but they wouldn't share it with me!
Yu Qiyan acted helpless. "Alright, we're old friends after all. If you don't have tungsten, I'll trade you ten green materials for one. Three tungsten ore plus 52 green materials will give you seven headlights."
Although Yao Yong felt a little distressed, he had to take out the materials to replace them when he thought of the usefulness of the headlights.
Next came Liu Jun. After Yu Qian'an's headlight message was sent, Liu Jun sent a message: "Brother Yu Qian'an, I'm here for a while, wait for me for a few minutes."
A few minutes later, Liu Jun replied, "Brother Yu Qian'an, we only have ten tungsten ores, but we want to buy more headlights. Do you think we can use other materials instead?"
Yu Qian'an: "If there is tungsten ore, it's one part tungsten ore plus four parts green materials. If there is no tungsten ore, it's ten parts green materials."
Liu Jun: "Okay, I'll buy fifty headlights, ten tungsten ores, and four hundred and forty green materials, right? Let's trade."
Yu Qian'an was stunned. This guy never bargained? Soldiers were known for their straightforwardness. How could retail and wholesale be the same?
However, Yu Qian'an did not intend to offer a lower price. After learning how to save tungsten ore, Yu Qian'an made another fifty sets of fill lights in one go and gave one set to Liu Jun: "Since you bought so many, I'll give you a set of fill lights as a gift. This will speed up the growth of plants."
Liu Jun: "Thank you!"
Finally, Yang Jiarui asked, "Yang Fuxing, do you want a headlight? Just ask and I'll send it to you right away."
Yang Jiarui: "Yes, please send it over."
Yu Qian'an: "Okay, I'll give you a friendly price. One part tungsten ore plus four parts of other green ores will give you a headlamp."
Yang Jiarui: "If there is no tungsten ore, does that mean we need ten green materials?"
Yu Qian'an: "How did you know?"
Yang Jiarui: "What do you think? I'm trading cherry tomatoes with Boss Yao Yong! You're such a profiteer!"
Yu Qian'an: "That's right, I didn't raise the price randomly, right?"
Yang Jiarui: "I want to buy ten and give you ten cherry tomatoes. Do you want to trade?"
Yu Qian'an: "No, it's a bit too little. I can't eat cherry tomatoes. And how can one cherry tomato be worth ten portions of green materials?"
Yang Jiarui: "Add two more green melons!"
Yu Qian'an: "Add five, no, the ones I planted aren't ripe yet, how come another wave is ripe?"
Yang Jiarui: "You are too dark, I will accept it...at most three!"
Yu Qian'an thought for a moment and said, "Five! You're so lucky, you must have more than one seed at a time. It's impossible for a vine to only produce one melon!"
Yang Jiarui: "I'm lucky and guilty, so I deserve to be ripped off by you?"
Yu Qian'an: "Then I'll just order three less cherry tomatoes, okay?"
Yang Jiarui: "Five cherry tomatoes and five melons!"
Yu Qian'an: "Deal!"
After exchanging five cherry tomatoes and five melons, Yu Qian'an washed them and started eating them directly. The melons were not as delicious as the blue ones, but they still tasted very good. After eating, Yu Qian'an's strength reached 22, his constitution reached 23, and his agility also increased a little to 18.
I opened the trading channel and saw a bunch of private messages. The most conspicuous one was a friend's message. I clicked it and it was from Lexing: "I also need headlights. How can I change them?"
Yu Qian'an sent a message to Le Xing: "What's your current health value?"
Le Xing: "Strength 18, Constitution 16, Agility 19. What's wrong?"
Yu Qian'an: "Do you have anything good?"
Le Xing: “No more!”
Yu Qian'an: "That's a shame. I just got a green melon. I think your strength and agility will 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! Even ten won't be enough!"
Yu Qian'an raised his eyebrows and said, "Tell me, if you have something good, I also have blue fruit that can increase your stats by more than ten points at a time!"
Le Xing: "I practice a family Qigong. I used to think it could strengthen my body, but after entering the game, I transformed it into a new attribute, internal force. I asked other people, but they didn't have it!"
Yu Qian'an: "Take a picture and let me see it!"
Le Xing: “Okay!”
When Le Xing's photo came over, Yu Qian'an saw:
Joyful Journey
Strength: 18
Constitution: 16
Agility: 19
Internal Force: 8
Mental Strength: 11
Health: 100%
Lucky:?
He really did have more internal strength than himself. Yu Qian'an hurriedly went to check on the melons he had planted, then came back and sent a message to Le Xing: "My melons will be ripe tonight or tomorrow morning. Let's exchange then!"
Le Xing: "There's no paper or pen here, so should I just dictate it to you?"
Yu Qian'an: "I have paper and pen. Wait a moment, I'll make one for you. Please write in detail later, otherwise I won't be able to get a stitch in the side when I practice."
