Life is difficult without being stingy and empty. Lin Yuan sighed while preparing to start his first deal since he became an executive.

This material information transmission and trading system is right next to the energy source tower, in a semicircular shape. When Lin Yuan clicked on the management options in his brain, he saw a white light slowly rising, and a very soft voice echoed in his mind.

"Dear S-325 sub-base executive, welcome to use the ninth generation material information transmission and trading system of the City of Machinery. Which service do you choose? This system is divided into free service and paid service. Information transmission and material transactions are free services, citizen transmission, latest information collection, data inquiry, and paid services!"

"Damn, it's so humane!" Lin Yuan complained in his heart, and then put the mechanical formic acid he collected before on the platform. There were 22 kilograms of these mechanical formic acid left. According to the acquisition price of the City of Machinery, he should be able to obtain 2,640 mechanical coins. By the way, he also checks his credit status. He is now owing 10,000 points, and there are still 20,000 points before bankruptcy, so it is not bad enough to be terrible.

And this trading system is indeed magical and fast, and it has already reached a conclusion in less than a second.

"Dear S-325 sub-base executive, the materials you traded this time are E3 standard materials purchased by the City of Machinery. The purchase price per gram is 0.12 mechanical coins, and the total balance is 2,640 mechanical coins. After testing, your account credit limit has exceeded 10,000 points. May I ask, is the balanced mechanical coins used to repay debts? Or, you can also choose to temporarily suspend repayment and purchase other materials, including directly trading in mechanical coins."

After hearing this prompt, Lin Yuan breathed a sigh of relief. He was worried before that the City of Machinery would use all his mechanical coins to repay their debts, and that would be the tragedy!

Of course, these mechanical coins were used to purchase other materials. Lin Yuan had already begun to fantasize about the various powerful equipment he could buy. However, when he chose to buy materials, a ruthless fact instantly defeated him and allowed him to fully see the price level of the City of Machinery.

"Dear S-325 sub-base Executive, given your current identity level and the total mechanical coins you have, you can purchase the following three items in total, A and F energy blocks, each energy block contains 100 units of standard energy, and sells for 200 mechanical coins; B and F mechanical warrior standard activity parts can be used to replace mechanical body consumable parts of F1-F4 mechanical warrior, and sells for 500 mechanical coins per piece; C and F energy laser gun standard replacement parts can be used to increase the range, power, cooling time of the laser gun, and sells for 1,000 mechanical coins per piece."

"Damn... it's so dark!"

Lin Yuan cursed in his heart, that's more than two thousand dollars, but he could only buy these three small things. Even such fragments are ridiculously expensive. No wonder this trading system service is free, and it must have been deducted from here.

Although Lin Yuan thought about it and removed option B. His mechanical body is still healthy now, and the replacement parts he saw in the three-dimensional projection seem to be better than what he modified? On the contrary, the standard replacement parts of the laser gun in option C are a model he has never seen before. This thing looks good at first glance, no wonder it costs 1,000 mechanical coins.

After the decision, Lin Yuan bought two parts of the laser gun and directly deducted two thousand oceans. The remaining 600 mechanical coins were purchased for three energy blocks. By the way, this thing was also urgently needed. At least before his energy source tower was restored, he could only rely on this way to buy it.

Fortunately, this energy block is not too expensive and he can barely afford it.

After the entire transaction process ended, the white light on the platform slowly rotated. In just three seconds, the mechanical formic acid on the platform quickly disappeared. At the same time, the items purchased by Lin Yuan were the items purchased. The whole process was extremely simple, convenient and fast, which made him feel extremely moved. The technological development of this mechanical city is beyond imagination. No wonder it can colonize the entire Milky Way. Compared with the technology on Earth, it is simply a difference between heaven and earth!

With this emotion, Lin Yuan picked up the energy block he purchased and the laser gun part.

The three energy blocks are only the size of a matchbox, silver-brown, very elegant, and can be absorbed directly, which is very convenient. As for the two laser gun parts, they look very ordinary, but based on Lin Yuan's countless dismantling experiences before, it is very different.

It is directly reflected in the strength. Both parts have a strength of 8.9, which is nearly half higher than the laser gun in Lin Yuan's hand. Moreover, these two parts happen to be an important part of the laser gun responsible for the energy conversion generator. Therefore, the benefits brought by this are obvious.

After carefully completing the parameters and various elevation and cross-sectional views of these two parts, Lin Yuan also had a picture in his mind. Without saying a word, he immediately began to install it on a laser gun and a sniper rifle. The improvement of combat effectiveness was also what he was striving to improve.

This kind of small task is nothing at all, it can be completely done in just one minute.

Lin Yuan praised perfectly in his heart, and pulled up his gun. At this moment, the exiled S-325, who was in the intelligence brain, got out of nowhere and shouted in a very surprised tone: "Oh my God, do you actually know how to repair and assemble? And you look quite skillful, it's incredible!"

Lin Yuan was so angry that he saw this bastard, he didn't even look at it, and raised his hand and shot it out with a shot.

But that guy seemed to care nothing. After all, he is just a signal now, not a mechanical body, so he will not die at all.

"Hey, hey, dear executive, please don't be angry. I apologize for my previous mistakes. Can you tell me your repair and assembly level? If your level is high enough, I think we still have a chance to make a fortune!"

When Zhou Yue heard the exiled S-325's words at first and then respectful, he felt a move in his heart. Could it be that the boy could not see his attributes? But thinking about it, he is a fifth-class citizen and an exiled person. He is completely a prisoner here. How can he be qualified to check the attributes of his executive officer? He probably has no authority.

As for the so-called opportunity to make a fortune, Lin Yuan is now sneering, grandma, I was hit in this big pit because of greed for pies falling from the sky. Do you want to expect him to be deceived for the second time?
