Shen Wang maintained a certain distance, avoiding arrays and dark sentries along the way, following neither quickly nor slowly.

"Is the mountain's defense always this rigorous?"

As he discovered the circumstances along the way, he grew more and more surprised.

Connecting the demonic energy on Han Wan'Er and this Cao Mingheng, Shen Wang confirmed there's quite a bit of intrigue here.

Cao Mingheng passed through several checkpoints in succession before arriving at a larger palace. The palace was entirely fiery red, with fire light emanating from it, and a flame burning inside. The plaque on the palace bore the words "Li Huo Hall" in silver base and red characters, neat and crisp.

Seeing this plaque, Shen Wang knew this was the place of the Master of Li Vein, who was also the first alchemist of the Celestial Travel Sect, known as the Medicine Emperor Red Sun Zhenren.

This person's cultivation was at the Golden Core Perfection, but due to his alchemy skills, his status was no less than a Nascent Soul True Monarch.

Shen Wang couldn't help but think of the Realm-Breaking Pill, a spiritual light flashed in his mind, could it be that this pill was fused with a certain amount of demonic energy?

He immediately frowned, "Is the Celestial Travel Sect crazy to even dare use demonic energy?"

Moreover, these people not only used demonic energy, they've used it to such an extent, even making it into a special medicinal ingredient?

Shen Wang hid himself, preparing to go in, suddenly sensed something midway, and quickly halted.

A strong wave of telekinesis spread outward, scanning the exterior. Fortunately, Shen Wang stopped in time, blending into the Five Elements, avoiding detection.

"The level of this telekinesis... Red Sun Zhenren actually broke through to the Nascent Soul Realm!"

He was rather surprised.

"Master, it's me, I've brought the Cold Ice Spirit Spring for you."

Cao Mingheng spoke.

"Hmm, I was worried about a Demon Beast infiltration."

An old voice sounded.

Shen Wang merged into a gust of wind entering the palace, hiding in the shadows.

Inside the grand hall, there was a massive alchemy furnace, red flames flickering beneath, with an open top. The palace had a specially designed opening, connecting inside and out, but the array barrier was currently isolating it.

Before the furnace, sat a withered elder, his face sallow, full of irritation, grey-black streams swirling in his eyes. He pointed to the side, telling Cao Mingheng: "Sit down."

Cao Mingheng sat beside him and said: "Master, this is the Cold Ice Spirit Spring, hoping to suppress your evil fire."

"It can't suppress it, only weaken it, preventing the demonic thoughts from invading the soul, completely driving one mad."

Red Sun Zhenren shook his head: "People from the Kan Vein still refuse to use the Realm-Breaking Pill? If more of their people broke through, more Cold Ice Spirit Spring or even Heart of Black Ice could be condensed to suppress the demonic thoughts."

"They still refuse, they don't want to touch demonic energy."

Cao Mingheng shook his head: "Hmph, I suppose they haven't really faced a catastrophe, afraid of everything at this time."

"Hehe, no need to force them, our refinement of the Realm-Breaking Pill is also limited, it's just that their strength being a step behind weakens our aid in suppressing demonic thoughts."

Red Sun Zhenren waved his hand.

Cao Mingheng handed over a bottle.

Red Sun Zhenren took it, opened it, and a chill emanated, frost instantly layering the surroundings. After drinking a sip, he showed comfort, his eyes cleared significantly.

He exhaled: "Though it treats the symptoms, not the root cause, it's much more comfortable anyway. A stable mind is needed to refine elixirs."

"Master, if we keep doing this, even if we fend off the Demon Race, I'm afraid we'll still go insane."

Cao Mingheng said helplessly: "The demonic energy within me is much lesser than yours, yet I've been feeling increasingly agitated lately, not knowing when I might lose control and become a Fallen Demon."

"No way around it, I've tried my best to refine the demonic energy, hoping to stimulate potential breakthrough through infusion into Elixirs, but there's no avoiding the issue of demonic energy entering the body, this force is too overpowering."

Red Sun Zhenren waved his hand: "It's your own choice, if you can't control yourself, go kill those Demon Beasts, don't turn here."

Cao Mingheng forced a smile, increasingly agitated within, resentfully saying: "Truly, we can still blame those Sun and Moon Dynasty people. If they hadn't pushed us, we wouldn't have chosen this path."

"Stop talking, adjust, and assist me in refining a batch of Demon Madness Pill, the Sect Leader has been urging, we've recruited many outsiders recently, must put them to use to eliminate some beasts."

Red Sun Zhenren waved his hand.

"Yes."

Cao Mingheng also took out a bottle, drank a small sip of the Cold Ice Spirit Spring to physically calm, and then helped at the side.

The hall quieted down, while Shen Wang, hidden and integrated into the Five Elements, pondered.

This Red Sun Zhenren and Cao Mingheng indeed absorb demonic energy to cultivate, but with quite clever methods, using the combination of demonic energy and Elixir to stimulate and break through potential.

Moreover, the Realm-Breaking Pill is indeed a special Elixir refined with demonic energy, utilizing the ferocity of demonic energy to stimulate potential for breakthrough.

In addition to the Realm-Breaking Pill, it seems there's also a Demon Madness Pill, mainly for cannon fodder to consume.

Wait a minute.

He just got recruited here today, will they want him to consume this stuff?

Shen Wang's expression became peculiar, but he had to admit, these people had quite the unique approach to utilizing demonic energy.

Whenever he encountered demonic energy, he would avoid it, yet these folks think of utilizing it?

Shen Wang pondered and came to a possible conclusion.

He might have had too brief an encounter with demonic energy, instinctively avoiding it.

The Celestial Travel Sect most likely had long-term exposure to demonic energy and conducted some research, resulting in the so-called Realm-Breaking Pill and Demon Madness Pill.

"Inside the Celestial Travel Sect, there's likely a source of demonic energy!"

Shen Wang's mind raced, quietly waiting for the two to prepare the alchemy.

The flames flickered, gradually growing larger, and various medicinal ingredients were taken out, all very ordinary types, in large quantities, indicating the Elixir about to be refined was quite low-level.

Cao Mingheng began processing various medicinal ingredients, while Red Sun Zhenren took out a jade token, forming a seal to activate the array.

Buzz!

During the vibration, the powerful array isolated inside and outside, and then within the change of array, a dense stream of demonic energy gushed out from the path behind the pill furnace, guided by the array into the alchemy furnace.

Shen Wang's gaze focused on the source of demonic energy, it was an underground passage. He very much wanted to investigate it. But at this moment, he dared not move.

Merging into the Five Elements allowed for very discreet camouflage, making even Red Sun Zhenren unaware of him, but if he got closer to the mouth of this demonic passage, he would inevitably be exposed.

He could only wait for another opportunity when Red Sun Zhenren left to explore.

"Seems there's a Demon Cave inside Celestial Travel Sect similar to the ancestral residence's, possibly always having demonic energy, thus having some level of research on it. Liu Shan was likely captured due to his unique condition for research and probably isn't dead."

Shen Wang looked at the two who relied on external substances to suppress their own demonic thoughts and understood the reason.

Judging by the few words left by Liu Shan, after being eroded by demonic energy, he hadn't lost his rationality, which is exactly what Red Sun Zhenren and others desperately wished for.

After all, these guys use demonic energy to break through, but are obviously troubled by the so-called demonic thoughts, easily turning mad. If they could stay clear-headed like Liu Shan, that would be ideal.

Sure enough, he wouldn't want to miss such a chance either.
