It's almost midnight on the 14th. He doesn't forget to lock the door in preparation. Last month, he still hadn't finished reading all the instructions on the system. Today, he needs to do it.

He prepared some things to sell today. Many of which he stole from his father's collection. Such as a sub-machine gun, a precious painting, a ship sculpture made of gold, and a Rolex watch.

He still never met his father of this world, Tim. "Just consider this a price for the late meeting", he tries to justify his actions. He doesn't know what the hell is it his father is doing as it's almost 2 months, but he still isn't home.

There are also gold bars that he bought by himself. 3 years of automatic allowance provided by his father has fattened up his bank account. When the delivery comes, Hiddle is greatly confused by his act of buying the stuff.

He looked out the window, it was now midnight. "The full moon is very beautiful today. " His point of view suddenly changes to a floating panel.

[Welcome to Interdimensional Trading Board]

"It's finally started." Ryan looks forward to this month's trade. The previous harvest, especially the gene optimization fluid, makes Ryan optimistic.

Now, his strength has reached 40 kg, weightlifting up to 100 kg and 16 seconds in the 100-meter dash. It's an improvement compared to the previous data and it's only been a month. It seems like the serum is more useful than he thought. Additionally, his height has now reached 1.8 m.

Quickly, he listed his stolen item on the market. The gold bar is sold to the system as he is afraid that the time is not enough. For the price of the item, he followed what was recommended by the system.

Finishing that, a messy marketplace is listed in front of him. "The interface sucks!", he cursed in his heart. It'll take forever if he wants to buy specific items. After selling his gold, he now has 500 tc in currency. It seems the rate of conversion is 5 grams for 1 tc.

"There's also some blueprints and books sold here. Hmmm, most items here are suspicious. There is no description, so how should I know what a 'Whisker of a nekomata' is?"

He goes through the confusion and takes his time to read the name slowly. He bought his first item today, a smartphone for 1 tc. It wasn't a phone he knew before, but it has a logo of a bitten pear on it." Is it a copyright problem? "

The phone seems advanced enough for him to not get uncomfortable. He tries to search for a blueprint of it. He figures he wants to create a smartphone, it'll be easier if there's a blueprint, right?

There's a blueprint for a smartphone, but the price is 150 tc. He checks the other listed blueprint; supercomputer 2500 tc, recording bug 110 tc, mini drone 160 tc... Etc. It seems like a blueprint is listed at a very high price.

When he checked the item price for a ready-made item, it was very cheap. A supercomputer only needed 100 tc." Why does this happen?"

If you stumble upon this tale on Amazon, it's taken without the author's consent. Report it.

When he thinks clearly, it's because the blueprint section provided the buyer with item creation abilities, rendering the item for sale obsolete. Ryan concluded it at the thought. It's not like there's anyone to confirm it for him, but it makes the most sense.

This is his understanding. "It's like an investment, buy the blueprint and I can sell the item in my world. I can make a lot more from this." He bought the smartphone blueprint after these considerations.

He started to focus on knowledge after he got the phone. He then bought material processing, R&D basic, basic programming, business management, statistics and analysis, component efficiency, and others that he could find.

It's not that he could buy the specific knowledge for it as he had no idea where to start. He spent almost 250 tc for knowledge only. It's all an investment for him. It'll cut down a lot of time for him to learn from scratch.

He got a notification that his watch and golden ship sculpture has been sold. It increases his fund by 300 tc. It took half of the session time for it to be sold.

"Basic exercise, Basic shooting, Basic swordsmanship, basic boxing, basic jiu-jitsu, basic karate, too many basic skills. I wanted more special ones". He's a little annoyed, but he bought all of it. A 100 tc basic exercise caught his eyes. All the others are only at 5 to 10 tc.

It was bought immediately and the skill he got is worth the price, but he didn't know it yet. This 'basic' exercise is from a cultivation world so the limit for a physical improvement of an exercise is greatly increased and the time taken for improving fitness is decreased.

A miniature drone with stealth function, a recording bug the size of a button, several rare books, fiction and nonfiction, and high-quality beer as the hiddle doesn't let him drink beer.

He also got an interesting item called the malice talisman. At first, he bought it because he wanted to know what it is, but the function is very neat.

The function of the talisman is to detect when someone is malicious to you. It can be used for a month. The price is 75 ts. When he gets to a higher level, he can buy the same item with a longer timespan. All together Ryan has almost finished all his trade currency today. There's less than 20 tc left.

There's still time, he clicked on to the bulletin board, and read the post from another trader. It shows a discussion about the perspective of a primitive civilization when contacted by a higher civilization. He paid 1 tc to read it.

The conclusion is that unless the people can accept or have the ability to comprehend that they are not the only species in the universe, the civilization should not be contacted as their development will askew.

There's nothing much to do except reading some articles to pass the time as his authority is still too low to have other functions.

Before the time ends, he checks back to the marketplace one last time. "OH MY GOD!!", he screams. The patrol outside is shocked and hurriedly knocked on his door. "Are you okay Mr. Knight?" The hire tries to open the door but it is locked. "Please stand far away from the door, I'm going to break it."

"WAIT!" Ryan yelled while going to the door and unlocking it. "I was just reading something on my computer. Please don't be so dramatic." He shows the patrol that he is fine. The old guy, who is an ex-navy, wished him goodnight before he left.

If the guy looks closely, in Ryan's bed, there are a lot of books scattered everywhere. He actually screams because he finds that someone is selling manga there on the marketplace.

He bought a lot of them until all his money was gone. He didn't regret his behavior one bit. "What's more important is that I HAVE ONE PIECE!".

He's very excited about it. He has a chance now. He can know the ending! He almost cried tears of joy when the manga was in his hand, but he held it in to make sure it didn't drip onto the book and destroyed it.

Today's trade ended in delight. For now, he has the related knowledge and blueprints to research how a smartphone is made. All his skills and knowledge have to be digested. Even if he already reaches a certain level in the skill from buying it, he feels like it's not his until he understands or practices with it.

He got a smartphone now. Even if it's a weird pear brand phone. It looks a lot like the iPhone 7. Many apps are useless as there's no wide network connectivity in this world, or any other people have the apps,....or a smartphone.

Such as social media apps. He can only use basic functions like the camera, surfing the Internet using a browser, and gaming. Luckily the phone comes with multiple games, if not there's no platform to download some games.

The seller is considerate on this part. If he didn't do it, the buyer had to make their own game and it'd take a lot of time. The seller is also too considerate as when he checks the gallery, it is filled with… stuff.

Some filthy stuff. Ryan disdains the seller on the surface, but secretly praises and admires the guy in his heart. He's a healthy man in his prime, he won't reject some enjoyable entertainment.

The manga is summoned back into the inventory. He will disguise it as he bought some items through the internet later. He took out one of them and started to read.

There's some isekai genre in the manga he bought. It makes him emotional. "Why can't that be me?", he says while sobbing at the happy scene of a man fluffing some wolf fur.

The next day when he wakes up, his eyes are red. Yawning, he greeted Hiddle when going to have some breakfast. Hiddle notifies him of something while he is eating." Your father is going to be home soon."
