Bale is a busy man, and so is Cavendish.

Both of them are workaholics with strong paranoia. They never take a vacation and spend 24 hours a day, or even 25 hours a day in the laboratory.

This was naturally a great thing for Rosen, but when necessary, it was quite difficult to get the two of them together for afternoon tea.

Either this person is busy, or that person is doing an experiment, or I am not free either.

In addition, the confidentiality level is also high, so it is quite troublesome to set up a bureau.

So, even though we were all at the Swan Lake in Mondania, we had never gotten together to have a good chat in nearly four years.

But this time, Rosen forcibly pulled the two out and had an afternoon tea party in the garden of Swan Castle.

"Your Majesty, I have a regular meeting later."

"Your Majesty, my experiment cannot be delayed."

Both of them looked anxious.

Rosen was calm and composed: "Okay, okay, I'll push it for you."

"Take a good rest this afternoon. By the way, I have a new idea that I want to discuss with you guys."

As he spoke, Rosen personally handed each of them 200 ml of the improved taste of Golden Blessing: "Come on, drink as much as you can. There's more left after you finish it."

Since this was the case, the two of them had nothing to say and could only relax and let their bodies collapse on the soft thick leather chairs.

Golden Blessing also needs to be drunk.

Because this thing is very refreshing and won’t make you sleepy after drinking it.

Rosen was in no hurry to talk about business, but also lay in the garden, basking in the golden sunlight of the warm winter sun.

After a while, when he was almost sleepy from the sun, Rosen suddenly asked, "Tell me, why is the sun always shining?"

Both Cavendish and Bale are people whose brains cannot stay idle.

After lying like this for a while, although it was comfortable, we all felt extremely bored.

When they suddenly heard Rosen's question, their minds started working rapidly.

A few minutes later, Cavendish looked embarrassed: "I never thought about this question. Now that I think about it, I don't know."

This is normal. After all, he has been focusing on the energy conversion array for these years. Although he has made great progress in a single point, he is almost a novice in other areas.

Bell has been studying various basic elements and how to use elements to combine new materials that meet the requirements, which is somewhat related to Rosen's problem.

He said: "I think the sun should be the source of everything."

"The Rings, the Elements, and everything we see, all come from the Sun. So does light."

To some extent, this may be true.

But Rosen laughed and said, "But my question is, why does it stay on? Won't the power run out?"

Bell was suddenly stuck.

After a long while, until he unconsciously drank 400 ml of Golden Blessing Oral Liquid, he finally spoke: "From the observation results, the sun is very big. Could it be filled with endless black stones?"

As soon as he finished speaking, Cavendish shook his head and said, "I just made a rough estimate. The black stone won't burn for that long."

He explained: "My estimate is that the sun will burn for a maximum of 5,000 years, but the history of the plane is much longer than that, and the sun in ancient times does not seem to have changed much from now."

So the two top geniuses in magic were speechless and subconsciously turned to look at Rosen.

Rosen spread his hands: "I don't know either."

Before disappointment could creep onto their faces, he added, "But I do have a vague idea."

The two of them immediately pricked up their ears.

Rosen squinted his eyes and looked at the sun in the sky.

"First, the sun is very, very large. According to the data from the Star Observatory, it is estimated to be several million times larger than our world."

"Then, the elements in the sun must be very, very numerous, almost infinite, right?"

Both of them nodded.

Rosen said, "Furthermore, the temperature of the sun must be very, very high. At such a high temperature, most elements must be in liquid or even gaseous form."

"That's right." Cavendish's eyes sparkled.

Bell looked thoughtful.

Rosen continued: "So, the sun should be composed of a gas with extremely high temperature and pressure."

"Why is the pressure so high? Oh, I see, because he is big."

The thoughtful look on Bell's face became more intense.

Cavendish was also enlightened. He whispered, "The larger the mass of an object, the more it will naturally attract each other."

"For an object as large as the sun, this attraction must be incredibly strong."

Bell made a silent estimate and was shocked: "If the sun is millions of times larger than our world, then even if it is composed entirely of the lightest elements, the pressure at its center is unparalleled."

Rosen nodded. "I did some calculations and found that we can already recreate a sun-like environment on Earth."

"Then we can see what happens."

After these words were spoken, Cavendish could no longer lie down and sat up straight.

"How is it possible to reproduce the conditions at the center of the sun on earth?"

He had just been silently estimating the approximate value of the pressure in his mind, and then he found that this pressure could easily destroy any object in the world.

Now that Rosen said that he could reappear on Earth, he immediately thought it was outrageous.

Rosen said nothing but looked at Bell.

Bell said softly: "From the perspective of pressure alone, it is very difficult. But I think the sun must have a force that explodes in all directions to resist the attraction between matter."

"Because if there is no such explosive force, I can't think of anything else in the world that can withstand such huge pressure. The sun must not be so big. It will keep compressing and compressing, and may even disappear into a small dot."

This is an extremely counterintuitive inference, and most people would never think of it.

Cavendish was a little slower, but he understood immediately: "This must be a force that is countless times more powerful than the most violent explosion of gunpowder in the world."

"If this explosive force and attraction cancel each other out, then the environment inside the sun may not be as harsh as simply speculated."

"How can we achieve this on earth, Your Majesty? Are you going to use the Ring of Strength to achieve this?"

He has already reacted.

Rosen nodded: "That's right, create a stronger power ring, construct a unique shape of pure force, restrain the elements, and then use the light of destruction to heat the elements to an astonishing degree, thereby simulating the environment of the sun."

"Then, maybe we can understand why the sun stays so bright."

The two mages became excited after hearing this.

After doing some calculations in his mind, Cavendish said immediately: "If we really find the reason, we can light up the sun on earth and obtain an inexhaustible source of power."

"This source of power must be countless times stronger than the black stone!"

Bell immediately thought in terms of elements.

After a long time, he said: "I think there may be a conversion phenomenon between basic elements."

Rosen was delighted to hear this and secretly sighed: "Hey, how did I find these two great treasures?"

He immediately said, "Shall we try it?"

Cavendish immediately said, "Your Majesty, if you want to light up the sun on earth, the current power ring is far from enough. I estimate that the scale must be increased by at least ten times."

Bell followed up, "Yes, the normal light of destruction is not strong enough, and to achieve a strong enough light of destruction, or other methods of heating the gas, it must consume a huge amount of power."

Rosen laughed and crossed his hands behind his head: "I only heard two words, money."

Cavendish and Bell looked at each other and chuckled.

"Your Majesty, you must be curious too, right?" Cavendish asked.

"Your Majesty, you must have a solution, right?" Bell asked.

Of course Rosen has a way, otherwise he wouldn't have brought this up.

He smiled and said, "This is a three-step process, from easy to difficult."

"The first step is to briefly simulate the solar environment in a very small area."

"This step is the simplest and can be achieved using focused light of destruction."

"I estimate that with the equipment and conditions of the Cavendish Laboratory, it can be done with a few modifications, and the cost will not exceed 100 million kle, right?"

Cavendish thought about it carefully and nodded, "Yes, it can be done."

"I feel like the first step of verification could be completed in three months."

Because most of them are ready-made.

Bell immediately said: "Then what can I do?"

Of course, Rosen had thought it through: "Provide various basic elements, try them one by one, and see if there will be any transformation of the basic elements."

Bell's eyes lit up and he jumped up from the recliner.

"What are you waiting for? Hurry up."

Cavendish also jumped up from his chair: "I'll do it right away!"

The two even forgot about etiquette and just ran away.

After running a few steps, Cavendish stumbled and was about to fall. Rosen quickly supported him with the mage's hand and said, "Alia, are you just standing there? Why don't you escort the two mages back to the laboratory?"

"Oh~Okay."

Ailia was a little sleepy while listening, but she immediately woke up as if from a dream.

In the following time, Rosen verified the life magic knowledge provided by Dora while waiting for news from the laboratory.

About two and a half months later, Rosen incidentally created a legendary +4 legendary wig, raising his basic soul strength to legendary 7.

It’s not that I don’t want to go higher, it’s just that my ability has reached its limit.

Then, the paper from Cavendish Lab arrived, titled “The Artificial Sun.”

The paper has two results.

The first one was exactly the same as Rosen expected, which was the discovery of the phenomenon of hydrogen isotope fusion under high temperature and high pressure, and the release of incredibly amazing power in the fusion.

The second one was completely unexpected for Rosen.

A strange substance was accidentally synthesized.

The substance possesses a durable property that is indestructible by conventional means.

If you want to destroy it, you can only simulate the solar environment again.

This thing was placed in an exquisite wooden box, with a magnifying glass installed on the top of the box.

The reason is that there is too little matter, just a small sphere with a diameter of less than one millimeter.

Rosen checked it out and at first glance it looked like a small stone.

Immediately try to touch it lightly with the legendary 7 mana.

It hit him once, and it was almost like hitting a stone. He himself didn't feel anything, but as time went by, Lai Fu reported something unusual.

'The phenomenon of mana solidification was discovered, the freezing rate is 0.01%, and the freezing attribute is unknown.'

The freezing rate was extremely low, far beyond the limits of mortal perception, but it was discovered by Lai Fu.

Rosen was startled, then his heart skipped a beat and many thoughts flashed through his mind in an instant.

Then, there was a burst of ecstasy.

"Hiss~ I think I touched the big treasure."
