Lu Yangxin said, "Your Yaoyang Sect really dares to dream, installing a complete Array Method around the sun."

"Solar energy includes both light and heat, and your Yaoyang Sect has monopolized it. What are the Demon Territory, East Sea, and Buddha Country supposed to use? Aren't you afraid they'll wipe you out?"

"There's also the far north; just because there are fewer people doesn't mean there are no Cultivators."

"It's already cold up there, and you're taking away the sunlight."

"This is like making enemies of the whole world."

"And with such a massive project, can your Yaoyang Sect actually pull it off?"

Hearing Lu Yang's soft sigh led the Sect Master to become anxious.

"Young Sect Master Lu, is there a problem with our plan?"

"There is an Immortal-level grand array on the sun that blocks it, forbidding anyone from approaching. Do you know who is responsible for this Immortal-level grand array?"

The Sect Master shook his head; they had investigated for a long time, many colleagues had died without uncovering the origin of the Immortal-level grand array.

With a grave voice, Lu Yang revealed a secret, "According to investigations by the Master of our sect, that array was laid out by both Emperor Qian, the first Celestial Emperor, and Emperor Yu, the first Wu Yao, respectively. It's a struggle between two Immortals separated by a hundred thousand years, involving even deeper matters not meant for you to understand."

"By setting up another Array Method around the sun, are you trying to get involved in the struggle of Immortals?"

In the past, the Yaoyang Sect might send people to the sun without Emperor Qian's concern, but if the Yaoyang Sect were to install another layer of Array Method around the sun, it would undoubtedly be a direct provocation.

If the Yaoyang Sect were to be destroyed by Emperor Qian, Lu Yang wouldn't care; one less demonic sect is actually preferable.

Lu Yang's concern was that Emperor Qian might act without restraint, using too powerful moves and harming the innocent.

Considering the actions of the mountain and river lords, it wasn't beyond possibility that their superior could do such a thing.

The Sect Master was shocked, breaking into a cold sweat. To think there were two sorts of Immortal-level grand arrays on the sun, involving the Yaoyang Sect in the struggle of Immortals could mean obliteration, a fate even worse than death!

"Have you researched anything else?"

"Yes, yes." The Sect Master hurriedly responded, continuing to search within his Storage Ring.

As he searched, he said, "While researching how to set up an Array Method around the sun, we incidentally discovered some by-products, such as..."

Lu Yang nodded, this time it sounded more reasonable.

Before he could see what the Sect Master had taken out, he found himself plunged into darkness, making Lu Yang worry that the Sect Master intended to take advantage of the chaos to harm him.

The meeting of The Three Great Demon Sects took place after the barbecue restaurant closed, at night, with the lights on in the hall.

As soon as the Sect Master took out the research achievement, it was as if a sinister wind blew through, extinguishing all the lights.

Fortunately, none present at The Three Great Demon Sects' emergency meeting were weak; they could all use Spiritual Sense, allowing them to see clearly without the need for light.

"What's the deal with your candle?"

Lu Yang observed with his Spiritual Sense that what the Sect Master had taken out was a large red candle. As soon as this candle appeared, all the other candles in the room went out.

"This is called a solar-powered charging candle. It can absorb solar energy during the day, and then can be lit at night."

"And the sudden darkness in this room is because...?"

"This thing can absorb all the light and heat around it, so naturally, there's no light left when it absorbs them," the Sect Master explained as if it was obvious.

"...Isn't the absorption efficiency of your candle a bit too high?"

If this is just a by-product of researching the sun's Array Method, the Cultivation World might plunge into an ice age and a dark era at the same time.

"Isn't it good to have higher efficiency?" Everyone says the higher the efficiency the better. In pursuit of ultimate efficiency, the Sect Master had spared no efforts.

"Keep it down, will you?"

"Alright."

"Old Chi, get us a box of these high-efficiency solar energy-absorbing candles for our Jiuyou Sect," Mu Baiyi said, showing great interest in the candles.

What a great invention, with these candles, why worry about lacking atmosphere at our meetings in the future?

Lu Yang didn't fully understand the aesthetic tastes of the Jiuyou Sect.

"Any other research results?"

"Yes, we've also discovered that we can use solar energy to boil water."

Lu Yang nodded, solar water heaters, I've seen these things before, they're handy.

Master Chi lit the candle, and the room once again became bright with light.

Master Chi brought out a large wooden barrel, which was another result of their research; it had absorbed solar energy during the day.

He filled it with water, and in just a few breaths, the water in the barrel began boiling, bubbling energetically with high efficiency, as usual.

Excited by the sight, Master Chi said, "We've also discovered that the steam produced from boiling water contains immense power, which could possibly be harnessed to do something with steam!"

"Although in this area, we've only conducted preliminary research and haven't achieved any significant results yet."

Lu Yang: "..."

This is the first time I've seen someone research steam machines in reverse from solar energy.

"Stop researching steam and focus on solar energy."

"Got any other research results?"

Master Chi scratched his head awkwardly; their main focus over the past year was on trying to establish an Array Method around the sun, which unfortunately, Lu Yang rejected. The solar candles and water heaters were merely byproducts.

"Although there are no other research results, our two sects' collaboration has uncovered that we can establish a new line of business."

"What new business?"

This time it was Mu Baiyi's turn to explain: "You see, in some places they have the custom of burial at sea, where bodies are given to rivers, lakes, and seas, to be consumed by fish, symbolizing a return to nature."

"We could expand our thinking and perform cremations by sending the bodies to the sun. According to the death statistics provided by Old Chi, even those at the Body Integration Realm would disintegrate into ash on the sun."

"Don't you see, the principle is similar to that of burial at sea, even more so thorough in death?"

"Considering that a person's soul only disperses seven days after death, we can schedule the cremation for after those seven days to prevent the soul from directly melting upon contact with the sun."

Clearly, Mu Baiyi had given this a lot of thought, even taking the folk custom of mourning in the first seven days into account.

"Young Sect Master Lu, do you think this business is feasible?"

Lu Yang was silent for a long time, then slowly asked, "Putting other aspects aside, running a barbecue joint while operating a cremation service, even that of cremation by fire, what do you think customers will think?"

The two sect leaders thought about it, and it did seem a bit inappropriate.

"Well, it's apparent you two have put a lot of effort into cooperative win-win strategies, but the thought process has gone astray. Keep up the good work!" like an elder brother, Lu Yang vigorously patted the shoulders of the two sect leaders, with an encouraging tone in his voice.

"If the candles and barrels can be mass-produced, they are bound to be widely popular."

On his way back to the Seek Dao Sect, Lu Yang suddenly asked,

"Elders, what do you think of Yaoyang Sect's research results?"

The Fifth Elder said earnestly, "They are suitable to join our Refining Peak."
