"What do you need? Just so you know, I don't have any firearms left to trade with you."
Ye Qiyan tapped on the light screen and sent the message.
After a while without a reply, Ye Qiyan thought the other party wasn't interested in trading anymore. Just as he was about to close the private chat, a message came through.
"Sorry, I was just taking a bath."
A bath?
Ye Qiyan silently glanced towards his reservoir.
How much water does this woman have to waste like that? He wasn't even that extravagant.
"No problem, so what do you want to trade? You should have seen what I just said."
Inside Shangguan Yingxue's train.
A girl with waist-length black hair stood up from a wooden tub that occupied most of the train. She twisted her long hair up, her light blue eyes revealing no emotion.
"32 kilograms of wood, 50 kilograms of metal, and 40 mechanical parts. You should have these."
Ye Qiyan raised an eyebrow, not answering the question but instead asking:
"These materials are for upgrading your train, right? How are you so sure I have them? Besides, even if I do, why wouldn't I use them to upgrade my own train?"
"Because I hate trouble. Before contacting you, I had already collected some materials, but it took too much time and involved talking to too many people, which I dislike. As for why I chose you, I figured you're the only one who could provide different materials at once. I calculated that you've sold over twenty rifles, and apart from food and water, what you traded for were various materials."
What she said was quite accurate, but not entirely.
Because Ye Qiyan had sold not just over twenty rifles, but double that—over forty.
As for the resources she wanted, Ye Qiyan indeed had them.
But he wasn't interested in trading them just for water. After all, his current reservoir was sufficient, and he even had a way to make it drinkable.
He'd found this method in the chat room.
Rubbing sticks to make fire, then boiling the water. No matter the taste, boiled water wouldn't cause death by diarrhea.
Of course, unless he was completely out of water, he wouldn't try this method.
Shangguan Yingxue was silent for a moment. She dried herself off and sent a screenshot.
"This should be enough."
[Water Purification Device] (Level 1)
[Can filter and purify wastewater, purifying one kilogram per hour]
Seeing the content of the screenshot, Ye Qiyan rubbed his eyes.
A water purification device?
So that's what it was?
No wonder this woman was extravagant enough to start taking baths. She must have obtained this device at the first station, and even bathwater could be filtered and recycled. Read this novel at novelping(.)com for the best experience.
Moreover, she probably had more than one.
No, she must have the blueprint for this device; otherwise, why would she be willing to trade it?
"Do you have the blueprint?"
"This device should be enough to trade for the resources I need."
She neither confirmed nor denied it.
Ye Qiyan put away his surprise.
The blueprint for a water purification device was certainly valuable, but it was someone else's possession.
He was already fortunate enough and had no need to envy others.
"Yes, we can trade."
The two completed the transaction.
After obtaining the water purification device, Ye Qiyan found it could be placed right between the reservoir's wastewater tank and the clean water tank.
Once activated, the purified water would automatically accumulate in the clean water tank.
This saved him quite a bit of trouble.
"Sublimation."
Having used sublimation so many times, Ye Qiyan roughly understood its rules. Such small Level 1 items didn't consume much stamina.
[Enhanced Water Purification Device] (Level 2)
[Can purify 3 kilograms of water per hour, can purify non-freshwater]
Upgrading it by one level tripled its effectiveness, and it gained the ability to purify non-freshwater, meaning even seawater could be purified.
Ye Qiyan was overjoyed.
On a whim, Ye Qiyan sent another message to Shangguan Yingxue.
"Have you upgraded your train yet? Can you tell me what happens after upgrading?"
He was curious about what upgrade options others would have after upgrading their trains, and whether they would be the same as his.
Shangguan Yingxue hesitated for a moment.
"...Alright."
Soon, a screenshot appeared before Ye Qiyan.
[Level 2 Train Upgrade Options]
[1: Basic Carriage Blueprint (zero Train Coins)]
[2: Welding Tool Set (two Train Coins)]
[4: Train stop time increased by one hour (two Train Coins)]
Options 1 and 4 were the same as when he upgraded, but the other two were different.
"I see, the carriage blueprint and stop time are fixed, while the other two are random, and their quality varies."
Shangguan Yingxue's two random options were much inferior to the ones he had received.
Ye Qiyan nodded in understanding, then saw Shangguan Yingxue send another message.
"Do you have Train Coins?"
"No."
"Then do you still want to buy water?"
Ye Qiyan's mouth twitched. If it were before, he might have bought some as a backup. But now, considering she had started taking baths, and the bathwater would surely be recycled using the purification device, buying water would mean buying her bathwater.
"No."
"Alright..."
The chat ended.
Ye Qiyan knew she wanted to buy Train Coins from him to purchase options, but he didn't have enough for himself, let alone to trade.
Besides, he still had an option he hadn't chosen.
[Train Burst Acceleration Device Blueprint (five Train Coins)]
One of the options available after upgrading the train to Level 2.
Five Train Coins might take several platforms for an average person to accumulate.
But Ye Qiyan, having just passed the second platform, had already amassed enough to buy all the options.
[Purchase: Train Burst Acceleration Device Blueprint]
[Consume 5 Train Coins]
[Current remaining Train Coins: 4]
[Train Burst Acceleration Device]
[Construction requires: 50 kilograms of metal, 200 mechanical parts]
[After constructing the device, materials can be used to create Acceleration Bullets. Using Acceleration Bullets can increase the train's speed to three times its original speed for ten minutes.]
So expensive, no wonder it cost five Train Coins to buy the blueprint.
However, he was only short a few parts.
And he could afford them.
Having passed the second station, the trading platform had become much richer.
And now, what most people needed was food and water, which he happened to have.
Ye Qiyan might be picky about those barrels of compressed biscuits, but that didn't mean they were worthless.
