A Brand New Concept

"Firewood? That's a valid interpretation too."

Xu Xinyao followed Xu Yuan's gaze to the ground and said softly, "Use the formation to conserve the Yin energy and life energy refined from those Strange Ghost and Yingui, store them in the Meson Lock for neutralization, and then activate the formation to guide them out when you need them."

"."

Upon hearing this affirmative answer, Xu Yuan unconsciously frowned, his gaze fixed on the ground as if piercing through the stone layers, watching over the countless Yingui and Strange Ghost imprisoned in the secret chamber below.

Looking at her Third Brother's solemn expression, Xu Xinyao hesitated slightly before asking:

"Brother, what's wrong?"

Xu Yuan took a deep breath, looked at Xu Xinyao, and asked in a low voice:

"I roughly understand the principle, but won't this cause a rejection reaction?"

Actually, compared to the word "firewood," the imprisoned Strange Ghost and Yingui below are more accurately described as "cauldrons."

Throughout the world, there are countless evil Cultivation Method, including some that use others as alchemical vessels. However, the upper limit of these Cultivation Method is extremely limited, and the reason for this is that they are considered unorthodox.

A cultivator's body is an extremely sophisticated instrument that rejects everything from others.

"Pfft."

Xu Xinyao's gentle laughter interrupted Xu Yuan's thoughts. She smiled and said softly, "Brother, you don't need to worry about that."

Xu Yuan raised an eyebrow slightly:

"What's the meaning?"

"Neither the Yingui nor the Strange Ghost have the concept of 'repulsion'."

"."

Xu Yuan's eyes widened for a moment, but then he seemed to realize something and felt relieved, rubbing his temples.

"That's true. Whether it's the Yingui or the Strange Ghost, they both seem to be able to evolve by devouring their own kind."

Xu Xinyao smiled slightly and took out a file from her Sumeru Ring, handing it to Xu Yuan:

"If you're really worried, Third Brother, then take a look at this file."

Xu Yuan glanced at it and saw a thin red string tied to the outer casing of the file.

As the highest "scientific research institution" of the Prime Minister's Prime Minister's Mansion, the Institute of Investigation stored a vast amount of files in many categories. To facilitate hierarchical access, the color of the binding rope was used as a marker.

The red string indicates that the file is classified as the third level, after black and gold.

Xu Yuan casually took the paper tube, opened the lid, took out the paper document inside, glanced through it briefly, and a hint of surprise flashed in his eyes.

Just then, Xu Xinyao's gentle explanation rang out at the perfect moment:

"This file records the state of the Yin Source refined by the hundred Yingui under the instrument. Without exception, the Source Essence refined by the hundred demon ghosts was all the same."

Xu Yuan gently put down the dossier in his hand and asked with some doubt:

"Source matter?"

Xu Xinyao slowly and gracefully sat back down in the wooden chair behind the desk, and instead of answering, asked:

"Third Brother, have you ever heard of the Primordial Qi?"

"I've heard of that before. Cultivators use their breathing techniques to refine the essence of heaven and earth into their own primordial energy. Once they reach a certain limit, they can break through to a higher realm." Xu Yuan replied without hesitation.

Cultivators practice two types of breathing exercises.

The first is to absorb Qi, and the second is to cultivate the source.

In the context of the game, the former is about restoring mana through meditation, while the latter is about increasing the maximum mana bar.

Xu Xinyao smiled slightly:

"Since you know that, Third Brother, you can understand this term as an appositive of the cultivator's original Qi in relation to Yingui."

Xu Yuan suddenly realized, pulled out a chair and sat down again, asking casually:

"The Institute of Investigation actually has instruments that can observe source matter? Could it be the new instrument you recently developed, Little Four?"

Xu Xinyao pouted and muttered under her breath:

"Brother, you really trust me. This was Father's plan back then. A long time ago, Father ordered the Institute of Investigation to investigate the anomalies among cultivators."

Upon hearing this, Xu Yuan pondered for a moment and instantly understood his father's intention:

"If we can overcome the repulsion reaction between cultivators, we can borrow the power of others when breaking through to a higher realm. Over time, the cultivation level of the cultivators in my Prime Minister's Mansion's Mansion will improve significantly."

"How easy is it to achieve something that no one in ten thousand years of cultivation has been able to do?"

"." Xu Yuan.

Xu Xinyao held the teacup in front of her with both hands, gently stroking the smooth rim of the cup.

"Over the years, although the ' Heaven-Peering Instrument ' developed by my master has enabled us to observe the cultivator's original Qi, that's all. My master has tried no less than a thousand methods to interfere with and change the cultivator's original Qi, but all of them have ended in failure."

At this point, Xu Xinyao sighed softly:

"This field has now been abandoned by Father. If it weren't for the need to address your physical changes, Third Brother, the Heaven-Peering Instrument, which was developed with countless resources, would have already deteriorated and broken due to lack of maintenance."

Xu Yuan listened carefully, and seeing the complex expression on his Fourth Sister's face, he asked with a light laugh:

"Are you interested in this type of research?"

"What, Third Brother, are you going to give me money?" Xu Xinyao looked up.

"It's not that it's impossible," Xu Yuan shrugged.

"But I remember Lou Ji took all your silver."

"." Xu Yuan.

After a moment of silence, Xu Xinyao shook her head:

"Brother, I'm not interested in the primordial energy. I know very well that with the current facilities and technology of the Institute of Investigation, we simply cannot solve the problem of the repulsion of primordial energy."

"I just feel that the Heaven-Peering Instrument developed by my master is such a masterpiece that it shouldn't be discarded like this."

Xu Yuan listened and Wan'er slightly:

"Xin Yao, with your status, it shouldn't be difficult to summon it, right?"

"The Heaven-Peering Instrument costs millions of taels of silver annually just for maintenance, and activating Heaven-Peering Instrument for an hour requires an astronomical amount of Source Crystal. Third Brother, do you think Father will agree to my willful request?"

"." Xu Yuan.

Well, no wonder that old man wanted to stop this project.

The study of primordial energy is a bottomless pit of money.

If there is any hope, then it is worth investing in, but this research clearly has no possibility of "monetizing" in the short term. It would be much more cost-effective to use these resources to research some war equipment and functional formations.

Xu Xinyao glanced at her reflection in the tea and said softly:

"Moreover, in order to observe the source essence of demons, the long-neglected Heaven-Peering Instrument was forcibly activated, and many of its components have already been damaged. Repairing it would be an exorbitant expense."

Frustration, disappointment, helplessness, and resentment.

Looking at the pitiful Dora A-Yao in front of him, Xu Yuan's eyes flashed with a thoughtful expression, and he gently tapped the table:

"Xin Yao, what is your purpose in wanting to borrow the Heaven-Peering Instrument?"

Upon hearing this, Xu Xinyao looked up, her bright, watery eyes blinking twice. She pursed her lips and said softly:

"In today's world, whether it's formations or equipment, they all rely on Source Crystal for power."

"But... but as you just saw, Third Brother, the yin energy of demons and ghosts can be controlled through array formations. If we make use of it, we might be able to create a completely new energy source, one that can be used indefinitely!"

Xu Yuan subconsciously raised his hand to touch his chin, then glanced at the ground again.

Through his Spirit Sight, he could sense the huge, newly opened chamber below, used to imprison Strange Ghost and Yingui.

To be honest, he was somewhat surprised by his Fourth Sister's statement.

This Fourth Sister's saintly heart seems to only apply to humans; she can't exploit these demon capitalists as much as she can.

After a moment's hesitation, Xu Yuan gently shook his head and pointed to the array in the secret chamber below, saying:

"The reason why Source Crystal are irreplaceable is not because they contain a large amount of Source Qi, but because they contain a large amount of Source Qi despite their small size."

At this point, Xu Yuan pointed to the array in the secret chamber below:

"This formation is too large; even if it could be accomplished, it would be redundant."

Xu Xinyao's voice carried a hint of urgency:

"Xin Yao has a way to solve this problem."

"Hmm?" Xu Yuan frowned.

Xu Xinyao stared at Xu Yuan, her beautiful eyes shining with excitement:

"Brother, do you still remember Senior Luo's Soul Ring?"
