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

Feng Yu could not believe his eyes.

The soul-summoning banner in his hand was his master's magic weapon, a magic weapon of a Nascent Soul expert.

Suppressing Lin Feng, a mere Core Formation cultivator, should be a piece of cake.

But the result?

The vengeful spirits within the summoning banner were completely emptied, while Lin Feng remained unharmed. This was outrageous; did Lin Feng also possess a method to counter Nascent Soul artifacts?

Even Qin Yuening was extremely shocked at this moment.

She thought Lin Feng was definitely dead.

After a brief moment of realization, she turned to look at Lin Feng and asked in an extremely incredulous tone.

"Lin Feng, what did you just do?"

Qin Yuening already knew Lin Feng's background, so Lin Feng had nothing to hide from her anymore. She chuckled lightly and said casually.

"You've forgotten, I have the remnant soul of the Underworld Emperor within me."

"The vengeful spirits created from these ordinary summoning banners are completely useless against me."

Qin Yuening nodded in sudden realization and said with great delight.

"Then, wouldn't all those ghostly or demonic arts be useless against you?"

Lin Feng nodded calmly, then turned to look at Feng Yu.

"Xu An, let's settle this score today."

Feng Yu, who was not far away, also heard Qin Yuening and Lin Feng's conversation.

I heard Lin Feng's name clearly, and I also heard about the remnant soul of the Underworld Emperor.

He stared at Lin Feng in shock and said in a trembling voice.

"You're not Song Xia, you're Lin Feng!"

"How is this possible? How did you end up in our sect?"

Lin Feng shrugged, ignoring Xu An's shock, and prepared to kill him directly.

After all, the City of Sighs is filled with treasures. Everyone else has already entered, and if Lin Feng doesn't hurry to find the treasures, someone else might beat him to it.

As for Xu An, this stumbling block, let's deal with him as soon as possible.

Lin Feng slowly walked towards Xu An, releasing the two remnant souls of the Underworld Emperor, instantly raising his cultivation level to the late stage of Core Formation.

Seeing Lin Feng's murderous gaze, Xu An finally realized something was wrong.

He dared not hesitate any longer and wanted to turn around and run away as soon as possible.

However, they were now in the City of Sighs, where the spiritual energy was extremely chaotic. Even if Xu An wanted to run, he couldn't run fast. He had only just turned around when Lin Feng, with the help of the jade pendant, quickly closed in on Xu An.

Lin Feng said with a cold smile.

"In my next life, I want to be a good person."

As soon as he finished speaking, Lin Feng unleashed the full power of the remnant soul of the Underworld Emperor.

Xu An wanted to resist, but the huge gap in cultivation level made all his efforts almost futile.

Before long, Xu An's consciousness was completely obliterated by the remnant soul of the Underworld Emperor. He was left with only flesh and blood, but he was like a walking corpse and had no power to fight back.

This withered body could not survive in the City of Sighs, so Lin Feng didn't need to deal with it anymore and could just let it fend for itself.

After finishing, Lin Feng turned around and walked towards Qin Yuening, saying calmly.

"The matter is resolved, let's go."

Qin Yuening glanced back at Xu An, a complex look flashing in her eyes.

Although she didn't like Xu An, they often cultivated together and shared some memories. Now that he had died in front of her, Qin Yuening couldn't help but feel a little emotional.

Lin Feng understood Qin Yuening's situation and didn't urge her, allowing her to take a moment to recover.

After taking a few heavy breaths, Qin Yuening came back to her senses and said calmly.

"Let's go."

Without further hesitation, the two continued walking forward.

The entry of others caused the spiritual energy in Sighing City to become extremely chaotic, and Lin Feng needed to rely on the power of the jade pendant to barely stabilize himself.

The two of them supported each other as they moved forward, searching for treasures hidden in the spiritual energy.

The two had been walking for less than a quarter of an hour when Lin Feng's jade pendant began to give off a warning, constantly emitting a crimson light.

Years of experience have taught Lin Feng that this is a sign of treasure.

He quickly stopped and pulled Qin Yuening back with him.

"Wait a minute!"

Although Qin Yuening didn't know how Lin Feng made his judgment, she was willing to trust him, so she stopped walking as well.

Amidst the chaotic spiritual energy, Lin Feng groped around for a moment and quickly found the place where the treasure was hidden. He reached out and touched it, only to discover that it was another immortal herb.

Because Lin Feng had only been practicing for a short time and did not have a clear master to guide him, he did not have much knowledge of many rare spiritual herbs.

Unable to determine the value of the spiritual herb, he could only take it out and hand it to Qin Yuening before asking her about it.

"Qin Yuening, what kind of treasure is this?"

Qin Yuening took the herb, examined it carefully, and then said with a look of shock.

"It's a restorative herb!"

"This is a top-tier immortal herb, possessing the purest immortal power!"

"Most pills can be made by adding it during the refining process to enhance their potency."

"But it is precisely because it is so pure that it is like the ephemeral beauty of the night-blooming cereus, fleeting and ephemeral."

"It's such a pity that we found such a treasure, but we can't take it out with us."

After hearing Qin Yuening's description, Lin Feng was stunned for a moment.

If that's the case, wouldn't this magical herb be wasted?

The ephemeral beauty of the herb was fleeting; its spiritual power quickly dissipated. By the time they left the City of Sighs, the immortal herb would likely have turned into withered grass.

Having finally found such a precious herb, Lin Feng didn't want to waste it. So, he gritted his teeth, took the herb, and stuffed it into his mouth to chew.

"I can't waste it anyway, so I'll eat it first."

Qin Yuening was startled when she saw this and quickly stepped forward to stop Lin Feng.

"Lin Feng, how could you swallow this magical herb raw?"

"Any kind of immortal herb, no matter how pure it is, will contain a large amount of spiritual energy that the human body cannot absorb if it is not refined."

"If you swallow it whole, this spiritual energy will accumulate in your body, and you will die."

Lin Feng naturally understood Qin Yuening's meaning.

Many medicinal herbs need to be refined into pills before they can be consumed; for an ordinary person to swallow them whole is tantamount to suicide.

But Lin Feng was never an ordinary person.

With the jade pendant protecting him, he wasn't worried about absorbing spiritual energy at all.

After swallowing the spiritual energy, Lin Feng immediately activated the jade pendant to quickly transform it into power that he could fully absorb.

"call!"

Lin Feng exhaled a long breath of stale air, and then began to quickly absorb this power.

As expected of a top-tier immortal herb, the spiritual energy it contains is indeed powerful. Lin Feng felt that his cultivation bottleneck was about to be broken through as soon as he began to absorb it.

With the help of the remnant soul of the Underworld Emperor, his cultivation could temporarily break through to the mid-stage of Core Formation. However, his own cultivation was still only at the Foundation Establishment stage, and the powerful force was allowing Lin Feng to break through rapidly.

"We're about to break through!"
