'It only takes 4,000 spirit crystals, and you can get nearly 700 spirit crystals every day. If I had known about this, I would have done it a long time ago...' Lin Yun sighed.
However, he only casually said this. This professional equipment for absorbing and refining spiritual energy, and that spiritual essence, only cost 4,000 spiritual crystals to buy back, and it was also because Xinglan sold it to him so cheaply.
Without Xinglan's help, he would not have spent so much.
Moreover, the 1,500 spirit crystals that Starry Blue gave him in advance when he bought the spiritual energy were just the difference, and he got 700 spirit crystals. All in all, he spent 6,000 spirit crystals, which was not even enough.
Before that, it was not easy for him to save up 6,000 spirit crystals.
And if he did, there would not have been as much spiritual energy absorbed and refined by the Cosmic Trading System.
In short, no matter what choice he made, the result would be more or less the same.
Right now, just this device can obtain nearly 700 spirit crystals every day. If he goes to a city with a large population and stays there, the Universal Trading System will obtain more than 300 spirit crystals every day, which adds up to more than 1,000 spirit crystals.
This amount is very large.
It can allow him to do many things.
A flash of brilliance appeared in the depths of Lin Yun's eyes.
At this moment, he truly had a strong foundation, and he could do whatever he wanted.
Because, next, even if he goes to the mountains and forests to stay, he can still maintain rapid development.
'The population of the Demon Capital is said to exceed that of the Deep City, so the next target is set in the Demon Capital. But, should I go to the Demon Capital myself, or should I leave the device there...' Lin Yun then pondered.
Soon, he made a decision. He was not familiar with the Demon Capital, so he would leave the device there and stay in the Deep City.
He did as he thought, because the time he wasted next would be a lot of mental effort.
Lin Yun went downstairs and quickly found an unoccupied place.
With a wave of his hand, he released an invisible flying car from the trading space.
The appearance of this flying car was not only almost transparent, but it could also quickly simulate the scenery outside.
From a close distance, the vision of a Blue Star human could possibly observe the existence of this flying car. Once it picked up speed, it was almost invisible, silent, and without a trace.
Anti-surveillance technology was naturally also available.
Therefore, although this flying car is not truly invisible, it is better than invisible in some ways.
Moreover, the defenses of this flying car cannot be penetrated by even the ordinary missiles of the Blue Star.
Naturally, the price of this flying car is also very expensive.
Lin Yun spent 800 spirit crystals to buy it.
If he was not currently financially comfortable, and if he discovered that the newly purchased equipment could generate 700 spirit crystals per day, he would not have been willing to purchase it.
Previously, the multi-purpose flying car he bought for those high-level robots only cost 30 spirit crystals.
In other words, no matter what it is, there are cheap ones and expensive ones.
For example, the vehicles on the Blue Star, the cheap ones can be bought for tens of thousands of dollars, and even if you buy second-hand ones, you can buy them for a few thousand dollars.
Expensive vehicles can cost millions, tens of millions, or even hundreds of millions.
The items on the universal trading system span many civilization levels, and the price difference is astonishing.
A cheap flying car can be purchased for a few spirit crystals.
Expensive flying cars are really expensive, costing tens of millions or even hundreds of millions of spirit crystals. Lin Yun dares not imagine how good an expensive flying car is.
Comparatively speaking, his flying car is really nothing.
However, compared to Blue Star Technology, his flying car is already very powerful.
Lin Yun felt that with this flying car alone, he could do many amazing things, and it was not something that ordinary forces could provoke.
However, Lin Yun also knew that once this flying car was exposed, it would also be amazing.
His current strength was not yet able to fight against such a storm.
He would not do so unless he had no other choice.
Xinglan was right, everything was about safety first, and not to be too hasty.
Many owners of the universe trading system, when they developed to a certain level, became arrogant and overconfident, and ended up dying before dawn.
This is a lesson learned the hard way.
His development has progressed at a speed that surpasses the majority of other owners of universal trading systems in the early stages. The time he needs to endure will be much shorter.
The speed of the flying car with eight hundred spirit crystals is not to be underestimated.
The distance from Shen City to Mo City is 1,500 kilometres.
It only took Lin Yun half an hour to arrive.
'Three thousand kilometres per hour, this speed is two to three times faster than an airplane. It really is worth the price. That flying car with thirty spirit crystals can only reach a maximum speed of 1,300 kilometres per hour...'
Lin Yun said in amazement.
Now, just going to the outskirts of the Demon City, even if that device can absorb and refine spiritual energy over a wide range, it cannot cover 20 million people. The population density of the Demon City is even lower than that of the Deep City, and it is not known whether a place that can cover 20 million people can be found.
The appearance of this flying car can simulate the scenery outside, so it is naturally a small matter to turn into the appearance of an ordinary car.
In the urban area of the Demon City, he could not fly as fast as before, so it was better to drive normally.
The Demon City was the top city in the Great Xia, and the various facilities and people were not comparable to those in ordinary places. Lin Yun was not sure if he would be discovered if he drove at such a high speed in the Demon City, so he was taking precautions.
An hour later, Lin Yun stopped in front of a piece of land in an upscale residential area.
This place was almost right. He felt that the speed of absorbing and refining spiritual energy was about the same as when he turned on the device in the Deep City.
Lin Yun casually threw a fist-sized black object, wrapped in the jade pendant, into a patch of grass, where it rolled to a spot without grass, before releasing some small tentacles that quickly burrowed into the ground.
This black object was purchased by him using ten spirit crystals, and was called the Diamond Blue Star.
Lin Yun closed his eyes, and he could sense that this Diamond Blue Star was burrowing into the ground very quickly, ten metres per second, and in just a minute, it had burrowed to a depth of five or six hundred metres.
In the grass, because this Diamond Blue Star is not large and does not drill a large area, the soil on top quickly covered it, and it looked like a small piece of land had loosened. There were plenty of these types of land, so it was nothing unusual.
It should be absolutely safe, Lin Yun thought to himself.
To ensure absolute safety, he had the Diamond Blue Star drill another two thousand meters down. At this depth, if it could still be discovered, he would be convinced.
Lin Yun then gave a faint smile and told the flying car to leave.
When Lin Yun returned to Deep City, he could feel his balance on the Universal Trade System start to soar.
He could obtain more than a thousand spirit crystals every day, and the rate at which this balance was rising was not to be trifled with.
