I, a centenarian, sweep through the gates of immortality.

The demonic cultivators present looked at each other in bewilderment and quickly came to a conclusion.

Lin Feng has gone mad!

A cultivator has many cultivation methods to choose from at different levels.

However, at the same level, one can only choose one cultivation method.

Now that Lin Feng has taken away so many cultivation techniques and claims he wants to cultivate them all, isn't he courting death?

He's probably not far off from going mad from his cultivation.

These demonic cultivators initially wanted to offer some advice, but then they thought that Lin Feng's death would actually benefit them.

If Lin Feng dies, wouldn't they be able to take a piece of the remnant soul of the Underworld Emperor from Lin Feng's body?

They wished Lin Feng were dead.

The most anxious person here was Yun Shu.

Although she acknowledged Lin Feng's descent into demonic possession, her true desire was to find a different path to survival.

Now that Lin Feng has to cultivate so many techniques, what if he suffers a qi deviation and becomes possessed by demons? Wouldn't all his previous efforts be wasted?

During the time she spent with Lin Feng, her feelings for him had undergone some subtle changes. She couldn't accept Lin Feng's death, nor could she take any risks.

She pulled Lin Feng aside and whispered urgently, trying to dissuade him.

"Lin Feng, different cultivation methods each have their strengths and weaknesses. If you cultivate them all, there will inevitably be conflicts."

Lin Feng naturally understood Yun Shu's good intentions. He smiled and said calmly.

"Although I haven't been in this path for long, I already know some of its intricacies. Why would I take the risk if I wasn't confident?"

After saying that, Lin Feng turned his head and glanced at the demonic cultivators. Although his expression did not change, a hint of disdain flashed in his eyes.

"I don't trust these demonic cultivators. I'll ask you to protect me from now on."

Yun Shu had no choice but to agree.

Without a moment's delay, Lin Feng found a deserted village and ordered the demonic cultivators to guard the perimeter. He left Yun Shu by his side and then began to study the cultivation techniques.

Although Lin Feng had not seen many martial arts techniques, he had gained some knowledge after the conflicts of this period. He could tell the difference in quality of these techniques after just a quick glance.

"These demonic cultivators' techniques vary in strength; we still need to see which one is more suitable."

"Let's try using those two remnant souls of the Underworld Emperor."

Lin Feng's confidence in practicing these techniques stemmed from his three souls.

Especially those two remnant souls of the Underworld Emperor, whose cultivation was originally extremely strong, but whose consciousness was erased by the jade pendant.

What Lin Feng needs to do now is to manipulate these two remnant souls of the Underworld Emperor to cultivate techniques and see which one is more suitable for him.

Since these two remnant souls have no consciousness, no matter how much they cultivate, it will be difficult for them to harm Lin Feng's divine sense. So Lin Feng naturally decided to give it his all and try.

Manipulating one of the remnant souls of the Underworld Emperor, Lin Feng began to try to cultivate the Blood Demon Sect's techniques.

"I don't know if it's suitable; I can only try it slowly."

Lin Feng, engrossed in cultivating his skills, was unaware that he had become the target of everyone's criticism.

The news that Lin Feng had entered the second Yin Pass and taken away the remnant soul of the Underworld Emperor quickly spread throughout both the righteous and demonic paths.

Xuanqing Temple, in particular, was filled with hatred at the mere mention of Lin Feng.

Several elders of Xuanqing Temple gathered together, gritting their teeth and cursing with resentment on their faces.

"That Lin Feng! He actually stole the remnant soul of the Underworld Emperor from the Bone-Illuminating Mirror again! If we can't get it back, all our previous plans will have been in vain."

"Lin Feng must die, otherwise, he'll definitely cause trouble!"

The people of Xuanqing Temple knew very well that they had been plotting for so long, even disregarding their reputation, all for the purpose of seizing the Underworld Emperor's Yin Pill.

With great difficulty, the arrays in Chongyang Valley and Qingfeng Valley were used to draw out a large amount of Yin energy, indirectly affecting the operation of the arrays in the Tomb of the Underworld Emperor.

Next, once the Tomb of the Underworld Emperor is opened, they will be able to take the lead.

Now things have gotten really bad. Lin Feng has actually taken away two remnant souls of the Underworld Emperor, and they have already become sworn enemies with Lin Feng, practically irreconcilable enemies.

If Lin Feng causes trouble and affects the competition for the Underworld Emperor's Yin Pill, the consequences would be unimaginable.

Upon realizing this, the elders all stood up and surrounded Venerable Xuanming, jointly petitioning.

"Sect Leader, this Lin Feng has become a major threat. We must eliminate him as soon as possible while his cultivation is still relatively strong!"

Clearly, Lin Feng's development has far exceeded Venerable Xuanming's expectations.

He originally thought that Lin Feng's cultivation level was low, and that even if he didn't take action himself, he could kill Lin Feng with the help of demonic cultivators and other forces.

Unexpectedly, Lin Feng joined forces with those demonic cultivators and even managed to seize the second remnant soul of the Underworld Emperor, which indeed became a major threat and had to be eliminated.

However, instead of choosing to exterminate them all, he thought of a better way to utilize Lin Feng.

Venerable Xuanming said expressionlessly.

"This Lin Feng can collect the remnant soul of the Underworld Emperor with ease. It seems that he is indeed special. Looking at his series of actions, he is also interested in the things in the Underworld Emperor's tomb."

"The Tomb of the Underworld Emperor is riddled with arrays, and various sects harbor their own ulterior motives. We happen to be short of someone to scout ahead, so let's lead Lin Feng there."

"Next, you will continue to hunt down Lin Feng, but do not kill him. You must force him into the Tomb of the Underworld Emperor."

The elders understood Venerable Xuanming's intention and readily agreed.

"We understand!"

After a day and a night of secluded cultivation, Lin Feng had finally gained a basic understanding of these demonic techniques.

Although they weren't yet proficient, these demonic techniques were more than enough to control the remnant soul of the Underworld Emperor.

Seeing that Lin Feng had finished his seclusion, Yun Shu quickly came over and asked with concern.

"Lin Feng, how is your cultivation going? Have you made any progress?"

Lin Feng did not answer, but silently summoned one of the remnant souls of the Underworld Emperor and used it to control his body.

A black light flashed in Lin Feng's eyes, and his entire demeanor changed drastically. The originally aged and composed Lin Feng disappeared, replaced by an old man with a sinister face.

Upon seeing this, Yun Shu was startled.

Thinking Lin Feng had been possessed, they quickly retreated.

However, what surprised him even more was that Lin Feng's strength at this moment had far exceeded that of the Foundation Establishment stage.

Even compared to experts at the Core Formation stage, they are not inferior.

"Lin Feng, you..."

At this moment, Lin Feng put away the remnant soul of the Underworld Emperor, returned to his original form, and then said with a smile.

"The remnant soul of the Underworld Emperor is already close to the peak of the Nascent Soul stage, but unfortunately my main body is only at the Foundation Establishment stage, so I cannot fully unleash its power."

"With the divine sense of a Nascent Soul cultivator combined with the cultivation of a Foundation Establishment cultivator, one can only exert the strength of a Core Formation cultivator."

"I suppose that should be enough to protect myself."

Lin Feng knew very well that cultivation was something that couldn't be rushed; it was best to take it one step at a time. The reason he was trying to force things to grow faster was simply to survive; he had no other choice.

"Alright, it's time for us to head to the next Yin Pass."
