Of the seven thousand spirit crystals, three thousand remain, which is far more than the few hundred spirit crystals Lin Yun originally planned to have left.

Don't rush to buy anything else. First, try out the equipment that professionally absorbs and refines spiritual energy, and see how effective it is.

There are many types of equipment that are professionally designed to absorb and refine spiritual energy. The equipment that Xinglan sold him was a regional type, which was also the type of equipment he originally intended to buy.

The principle is similar to that of the Cosmic Trading System. Wherever the Cosmic Trading System is located, it can absorb and refine the surrounding spiritual energy.

This device is similar, but its range is within a radius of thirty kilometers.

"Luckily, the radius is thirty kilometers. Otherwise, even if it could absorb and refine the spiritual energy of twenty million people, it might not be able to cover twenty million people..." Lin Yun sighed.

A radius of 30 kilometers can cover the entire city of Shenzhen, including all remote areas, and much more. A long time ago, the Shenzhen municipal government claimed that the city had 20 million people. Now, it's time to verify that claim.

It's called equipment, but it's actually just an item the size of a jade pendant, and its design is similar to that of a jade pendant.

There's a small bump on it; just press it and the device will start.

Normally, it doesn't need to be given energy; it will replenish its energy by absorbing spiritual energy.

"drop!"

First, pair the device with his cosmic trading system. Then, the spiritual energy absorbed and refined by the device will automatically be transferred to the balance in his cosmic trading system.

As long as the device is not damaged or turned off.

No matter where he is, this device will continuously transmit spiritual energy to him.

Just like Xinglan, as he sails through the sea of ​​stars, he will still receive the spiritual energy generated by the civilization he belongs to.

If someone shuts down the device and then restarts it, it will need to reconnect to the Cosmic Trading System.

To prevent spatial transmission anomalies during transactions, this device must be turned off.

This also prevents some owners of cosmic trading systems from selling second-hand equipment and then having it absorbed and refined by other owners of cosmic trading systems.

Lin Yun first shut down the ability of the cosmic trading system to absorb and refine the surrounding spiritual energy.

"Buzz—"

He then pressed the protrusion and immediately felt a special fluctuation emanating from the "jade pendant" and spreading rapidly in all directions.

"Splash splash splash—"

At the same time, Lin Yun "saw" that the balance of spiritual energy on the cosmic trading system, which had just stopped moving, was rapidly increasing again.

"Before it integrates with the second level of spirituality, this device can only absorb and refine the spiritual energy of ten million people. Covering ten million people within a radius of thirty kilometers is more than enough. It all depends on the current speed at which it acquires spiritual energy..."

Lin Yun closed his eyes and said silently.

Previously, he had no concrete idea of ​​how many people the Cosmic Trading System could absorb and refine spiritual energy from, so he was also unclear about how much spiritual energy one person could provide to the Cosmic Trading System each day.

Now, he can do the calculations.

"At the current rate, we can obtain 230 spirit crystals a day!"

Soon, Lin Yun opened his eyes, looking surprised.

Is this really the spiritual energy that ten million people can generate every day?

It should be noted that the efficiency of this device in absorbing and refining spiritual energy is far less than that of the cosmic trading system.

The efficiency of the Cosmic Trading System in absorbing and refining spiritual energy is not 100%.

According to official data from the Cosmic Trading System, the system itself is about 90% efficient, while the device he purchased is about 60% efficient.

Half the difference!

In other words, if the spiritual energy of these ten million people were absorbed and refined by the Cosmic Trading System, nearly three hundred and fifty spiritual crystals could be obtained every day!

His cosmic trading system can only generate 350 spirit crystals per day at present!

In other words, his cosmic trading system's ability to absorb and refine spiritual energy currently only covers about ten million people.

He thought that his cosmic trading system's absorption and refining of spiritual energy had covered most of the bustling urban areas of Shenzhen. If Shenzhen's population exceeded 20 million, he should have covered more than half of the population, or at least 13 or 14 million.

Thirteen or fourteen million people... ten million people... that's a difference of thirty or forty percent, a difference of three or four million people, that's a huge difference.

Because a radius of 30 kilometers already covers the entire Shenzhen city area, which must include 10 million people, this device has not yet been integrated with the second level of spirituality, and can at most absorb and refine the spiritual energy of 10 million people.

Therefore, this data is very accurate.

So, his previous calculations were wrong, and quite wrong at that; perhaps... he was wrong from the very beginning.

He originally thought that the spiritual energy generated by each person on Earth was about 150 times that of the people on Star Blue. Later, based on new data, he continuously revised the figure, and the multiple increased again... However, most of this data was based on previous small data.

Just like his previous calculations, how much spiritual energy could a building with 20,000 to 30,000 people obtain each day, and then compare it with the people on Xinglan's side.

However, this figure of 20,000 to 30,000 is too general. The difference between 20,000 and 30,000 is 50%. If the actual number is higher or lower, the difference will be even greater.

The data discrepancy wasn't too noticeable in the early stages, but it became increasingly larger in the later stages.

This is what is meant by "a small difference can lead to a huge error".

Lin Yun's feelings were complicated.

He was somewhat speechless at the fact that the cosmic trading system currently covered so few people.

Soon, he was happy again.

The fewer people the cosmic trading system covers, the better, indicating that Earthlings have greater potential, and the more spiritual energy they can obtain daily from the device they purchase.

"Spiritual integration into the device..."

Then, Lin Yun took out the level-two spiritual energy and looked at the device.

Integrating spiritual energy into the device is very simple; Lin Yun just needs to place the spiritual energy on it, and the device itself has the ability to absorb spiritual energy.

"Buzz—"

As his spiritual energy merged with the device, Lin Yun immediately sensed a dramatic change. It seemed to have become a living entity, emanating a wave even stronger than the previous one, which rapidly spread in all directions.

"Whoosh—whoosh—whoosh—"

Lin Yun immediately "saw" that the balance of spiritual energy on the cosmic trading system began to surge.

This speed is not just twice as fast as before, it's almost three times faster!

"So much spiritual energy..." Lin Yun's expression changed again.

Only then did he remember another major function of the Level 2 spiritual integration equipment... it could increase the equipment's efficiency in absorbing and refining spiritual energy by 30% to 50%!

"At the current rate, I can obtain nearly seven hundred spirit crystals every day!"

"In other words, this device can absorb and refine spiritual energy in a range that covers 20 million people, and its efficiency in absorbing and refining spiritual energy has been increased by 50%!"

Lin Yun quickly obtained two data points.

This 50% increase doesn't directly increase the efficiency of the equipment by 50%. The equipment's original efficiency was 60%, so a 50% increase would bring it to 110%. There's only so much spiritual energy; no matter how you absorb and refine it, you can't increase it any further. Lin Yun already knew this.

This efficiency is 50% higher than the original 60%, which is 90%!

This improvement is arguably the greatest among spiritual effects, indicating that Lin Yun's level two spiritual effect is extremely good!

Now, the efficiency of this device in absorbing and refining spiritual energy is comparable to that of the Cosmic Trading System!

"The effect of this spiritual energy is truly powerful! Fortunately, I sold it to Xinglan earlier; if I had sold it to someone else, the loss would have been too great!" Lin Yun took a deep breath and thought to himself.

Without integrating this spirituality, even if the device can absorb and refine the spiritual energy of 20 million people, he can only obtain less than 450 spiritual crystals per day!

You'll be getting about 250 fewer Spirit Crystals every day!

Even if we don't talk about a long time, just a few days of his spiritual essence would result in a huge amount of loss!

As for the long term, the losses will be even greater!

If he had sold this level-two spiritual essence to someone else for just over a thousand spiritual crystals and then never bought it back, he would have regretted it terribly!

Once you miss out on this kind of spirituality, who knows when you'll get it again!

As far as he knew, Xinglan had ruled their civilization for thousands of years, and after searching their entire civilization, he had not found a single second-level spiritual being, only a few first-level spiritual beings!

Thinking about this, he felt even more grateful for Xinglan's help back then!

"It seems I need to find some of these spiritual beings when I have time, otherwise, the efficiency of absorbing and refining spiritual energy with just equipment is too poor..." Lin Yun murmured.

Now that he has experienced the efficiency of equipment infused with spirituality, it is unbearable for him to accept the efficiency of equipment without spirituality.
