However, people outside cannot probe the situation inside the cultivation room, yet within the cultivation room, it is possible to observe the situation outside. If Wu Tianyu appears, Lin Feng can discover the opponent.

Dividing a strand of his mind to pay attention to the external situation, Lin Feng did not rush into cultivation, but pondered for a moment before calling out with his thoughts to Yama Demon Saint: "Predecessor Ghost Saint!"

"What is the matter?" asked Yama Demon Saint softly.

"Predecessor Ghost Saint, do you have a way to enhance my power within a year?" Lin Feng inquired in a serious tone.

"Enhance your power?"

Upon hearing this, Yama Demon Saint remained silent for a while, and then said: "You can just kill and devour, why do you need my assistance?"

"This... I’m not looking to enhance my cultivation, but to boost my combat strength." Lin Feng clarified.

He wanted to stand out in the Junior Officer selection, but simply enhancing cultivation wouldn’t help since no matter what level he reaches, there are countless people with higher cultivation.

He must achieve invincibility at the same level to have a chance to become a Junior Officer.

"Enhance combat strength? How much enhancement?" Yama Demon Saint inquired.

"At least improve by tenfold!" Lin Feng said.

Yama Demon Saint nearly choked upon hearing this, tenfold improvement? A Martial Artist in the Martial Emperor Realm wanting a tenfold enhancement in a short period?

This is daydreaming!

"I cannot achieve that!" Yama Demon Saint stated forthrightly.

"Then... a sevenfold enhancement, surely you can do that?" Lin Feng asked again.

"Barely." Yama Demon Saint replied.

Upon hearing this, Lin Feng was overjoyed and hurriedly asked: "Then quickly tell me!"

"One year is not a long time, but not too short either. I will impart to you the Holy Level Upper Grade cultivation technique ’Heavenly Chaos Demon Technique’. With your insight, you can roughly achieve a seven to eight fold enhancement in combat power within a year!" Yama Demon Saint stated.

"Heavenly Chaos Demon Technique?" Lin Feng’s eyes brightened upon hearing this, feeling slightly excited. A Holy Level Upper Grade cultivation technique, the opponent actually passed him such a high-level technique!

"Indeed! This is a secret of the Demon Clan, there aren’t many martial arts that surpass this technique in the Ancient Spirit Star River!" Yama Demon Saint nodded and said.

"Alright, please bestow it upon me, predecessor!" Lin Feng stated seriously.

Immediately, Yama Demon Saint sent a torrent of boundless information into Lin Feng’s mind through his thoughts.

This information was indeed the spell of the Heavenly Chaos Demon Technique, profound, intricate, and obscure.

Lin Feng was very excited, a Holy Level Upper Grade cultivation technique! Much stronger than any he has cultivated in his original form.

Although he lamented a bit inwardly, such a powerful technique being cultivated with this flesh body seems a waste.

Because no matter how powerful this body becomes, it’s ultimately not his own body, and he would have to abandon it in the future.

But under current circumstances, he can only cultivate this flesh body.

However, Yama Demon Saint actually passed such a powerful technique to him, does the opponent have such goodwill? Lin Feng was somewhat skeptical.

Nevertheless, he had no other solution at the moment and could only cultivate it first.

"Lin Feng, I will now explain the profoundness of this technique to you in detail!" Yama Demon Saint said.

"Thank you, predecessor!" Lin Feng replied solemnly.

"First, when cultivating the Heavenly Chaos Demon Technique, you must be mentally prepared. This is a forbidden cultivation technique of the Demon Clan, extremely powerful and awe-inspiring. Cultivating it requires enduring immense pain, and any mistake can cause you to go berserk, with magic backfire leading, at best, to the loss of personality, turning into a bloodthirsty killing demon, and at worst, death by body explosion." Yama Demon Saint first warned.

Lin Feng’s eyebrows jumped upon hearing this, if the opponent tampered with this technique, cultivating it would spell disaster for him.

However, Lin Feng soon discarded this concern, if the opponent intended to harm him, they wouldn’t have warned him about these things.

Besides, if any mishaps occurred during cultivation, he could eliminate the opponent immediately; the opponent should know this.

In short, Lin Feng was now riding a tiger, having no choice but to proceed step by step.

Next, Yama Demon Saint elaborated in detail the intricacies of the Heavenly Chaos Demon Technique to Lin Feng, including various cultivation points and precautions.

The explanation went on for several hours, allowing Lin Feng to gain a very thorough understanding of the Heavenly Chaos Demon Technique.

For a cultivation technique of this level, without Yama Demon Saint’s explanation, even if he possessed the entire spell of the technique, he wouldn’t be able to comprehend its profundities.

It was simply too profound, beyond his current realm and impossible for him to understand.

"Cultivating this technique primarily requires guarding your heart, and a firm will, only then can you reach the advanced realm." Yama Demon Saint reminded him.

"Rest assured, predecessor! I won’t let you down!" Lin Feng nodded and said.

"Hmm! With your level of understanding, completing the First Layer Realm within a year shouldn’t be too difficult!"

The Yama Demon Saint seemed quite confident in Lin Feng, and added, "Go ahead and cultivate! If there’s anything you don’t understand, come and ask me!"

Then, he fell silent.

Shortly after, Lin Feng discarded all distracting thoughts and carefully reviewed the various key points of the Heavenly Chaos Demon Technique in his mind before beginning his cultivation.

This cultivation technique comprises seven realms, and with every rise in a realm, its power increases tenfold, truly defying the heavens.

If he could fully master the First Layer Realm, his combat power would immediately surge seven or eight times.

With a thought, Lin Feng’s Divine Pill trembled within him, as a vast amount of Dark Power surged from the Divine Pill, circulating through his meridians.

He started formally cultivating the First Layer Realm of the Heavenly Chaos Demon Technique.

This operating route was vastly different from the cultivation technique Wu Chen practiced, encompassing all twelve primary meridians and the eight extraordinary meridians.

As the Dark Power completed a Grand Circulation within his meridians, the flowing Dark Power gradually changed its attribute, its color transforming to pitch black.

The once calm Dark Power gradually filled with a violent aura; it was transforming into Magic Power, gradually enhancing its potency.

Consequently, the Magic Power stimulated Lin Feng’s body, causing him to tremble slightly all over.

Lin Feng concentrated his mind at the Dantian, maintaining his inner focus, never ceasing his cultivation.

This conversion process of the cultivation technique was to last a long time.

At this moment, Lin Feng turned his hand, and appeared in his hand were over a dozen Low Grade Spirit Crystals, which he pressed firmly into the array groove beneath him.

Since his original cultivation technique level was only Upper Grade Emperor Level, the Dark Power in the Divine Pill was extremely limited, insufficient to successfully convert the technique, requiring a lot of Spiritual Energy.

Buzz buzz~~~

With the Spirit Crystals entering the array groove, the array in the cultivation room immediately activated, connecting to the Earth Dragon Vein beneath the Tianming Star.

Boom!

Instantly, a vast amount of Spiritual Energy mixed with Earth Essence Qi surged up from below, rising like mist, permeating the entire cultivation room.

The so-called great Earth Essence Qi is actually Spiritual Energy, just rich in Earth Attribute.

"So powerful!" Lin Feng was amazed within; the concentration of Spiritual Energy in this cultivation room was at least a hundred times that of the outside world.

No wonder so many helpless young people come here to cultivate; it truly is a superb cultivation paradise!

"Devour for me!" Without hesitation, Lin Feng slightly urged the Devouring Battle Soul, beginning to absorb the Spiritual Energy.

The rich Spiritual Energy, under the absorption of the Devouring Battle Soul, instantly crazily drilled into his body, and the Spiritual Energy in the entire cultivation room was instantly sucked dry.

However, the array in the cultivation room connected with the Dragon Vein beneath the earth, providing a continuous flow of Spiritual Energy.

Lin Feng concentrated with serenity, while simultaneously devouring Spiritual Energy and cultivating the Heavenly Chaos Demon Technique.

The conversion of the cultivation technique is not a matter of a day or night; it is necessary to completely transform all the Dark Power contained in the Divine Pill into Magic Power.

Buzz buzz~~

As time slowly passed, the Spiritual Energy flowing from the array couldn’t keep up with Lin Feng’s devouring speed; all the Spiritual Energy seemed to be directly siphoned out from the array by the Devouring Battle Soul.

Within the entire cultivation room, Spiritual Energy reached its peak density, becoming a thick Spirit Fog.

Lin Feng was wholly immersed in cultivation, unaware that his devouring affected everyone.

Outside.

There were still many waiting because there were too few cultivation rooms available.

Bang! Bang! Bang!

At this moment, many doors of the cultivation rooms opened one after another, and the young Witch Clan members walked out.

"What’s going on? Why has the Spiritual Energy inside the cultivation rooms become so weak?"

"No idea! I was just breaking through a cultivation bottleneck when the Spiritual Energy suddenly stopped!"

"Damn, what’s going on?"

"Could it be a problem with the Earth Spirit Tower?"

People started speaking out, all with puzzled expressions, and some even cursed angrily.

Some were at a critical point of breakthrough in their realm when the Spiritual Energy abruptly vanished, causing great frustration.
