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

Upon returning to Zhongzhou once again, all three were somewhat heavy-hearted.

For Lin Feng and Yun Shu, this was the place where they had lived for nearly a hundred years. Their former sect had been destroyed by a major sect in Zhongzhou. They carried a deep-seated hatred and resentment that lingered for a long time.

Although Liu Qingqing's emotions were not so intense, it was still her hometown, and she couldn't help but feel a little sentimental.

"Ugh."

"Life is unpredictable, and fate is fickle."

Lin Feng looked towards the direction of Chongyang Valley in the distance, a murderous intent flashing in his eyes.

Chongyang Valley's kindness to him was the most important help he had received since embarking on the path of cultivation.

Now that Chongyang Valley has undoubtedly been slaughtered, only he and Yun Shu are left alive. If he cannot take revenge, how can Lin Feng's Dao heart remain stable?

He said coldly.

"Venerable Xuanming's lifespan is running out, we must hurry. If we cannot kill him with our own hands, how can we avenge this hatred!"

Yun Shu nodded repeatedly, her face full of resentment.

"I will tear him to pieces!"

After saying that, the group quickened their pace and hurried towards the City of Sighs.

After the previous catastrophe, Sighing City was now nearly destroyed. The array used to gather spiritual energy had long since collapsed, and the vast spiritual energy spread wildly, leaving the surrounding area barren for miles around.

However, for those disciples of the Demonic Sect, such an environment has become a breeding ground for their growth.

After all, the pursuit of those prestigious sects is endless. If they go to a good place, they may be killed by the prestigious sects at any time. On the contrary, in such a harsh place, they can at least survive.

Looking at the rampant spiritual energy before him, Lin Feng stopped Liu Qingqing and said calmly.

"Qingqing, you and the children can wait outside."

"The environment here is too dangerous. If a battle breaks out, I won't be able to take care of these children."

Liu Qingqing had already reached the Nascent Soul realm, and unless the leaders of the major sects intervened, she would be invincible.

Therefore, she preferred to go into Sighing City with Lin Feng, so that she could protect him and prevent any accidents from happening.

Now that she heard that Lin Feng wanted her to stay outside, Liu Qingqing naturally disagreed.

"Lin Feng, aren't you in danger going in alone by yourself?"

For Liu Qingqing, her parents had long since passed away, and her master had also died tragically. Now, the only person she cared about in this world was Lin Feng. She didn't want Lin Feng to take any risks.

Lin Feng could understand Liu Qingqing's good intentions, but the current situation was complicated. Although Liu Qingqing's cultivation was high, once she entered, it would be difficult for her to provide any help to Lin Feng, and she might even be a hindrance.

Because the formation of the City of Sighs was designed from the beginning, the higher one's cultivation level, the more severe the damage one would suffer.

Therefore, if Liu Qingqing, as a Nascent Soul expert, were to follow Lin Feng into the cave, it would likely increase the difficulty for Lin Feng.

Lin Feng pointed to the ruins of Sighing City and said with a smile.

"You can go in and try it now."

"As a Nascent Soul expert, once you enter, the power of the formation will definitely double after it is activated."

Liu Qingqing didn't quite believe what Lin Feng said, but she still decided to give it a try.

He walked into the ruins of the City of Sighs, and the next second, the originally calm spiritual energy suddenly became violent, as if it had been sensed by something.

This violent spiritual energy has far exceeded Lin Feng's ability to withstand it.

Seeing this, Liu Qingqing had no choice but to retreat.

"You're right, the strength of the formation here does vary from person to person. If I go in with you, it will definitely increase the difficulty for you. I'd better wait outside."

Although Liu Qingqing was worried about Lin Feng, she thought about it again. At the same level, Lin Feng was invincible, and with the help of the little Pixiu and various divine artifacts, he didn't really need to worry too much.

Yun Shu's cultivation level was too low, so she could only stay outside, leaving Lin Feng to enter alone.

Lin Feng nodded, offered a few words of reassurance to the group, and then turned and entered the depths of Sighing City without looking back.

Although the entire Sighing City has been destroyed, its spiritual energy is still extremely rich. Lin Feng can use the jade pendant to convert this spiritual energy into his own use.

As a born sword embryo, Lin Feng's cultivation level will improve extremely rapidly as long as he is nourished by spiritual energy.

His only concern now is not being disturbed while he is improving his cultivation level.

Since Liu Qingqing and Yun Shu are outside, and there is no one to protect Lin Feng, he now has to choose a safe place.

Lin Feng surveyed his surroundings, still faintly sensing the presence of many disciples of the Demonic Sect.

And the only place in the entire City of Sighs where no one is active is probably the city center.

That's where the Sighing City's formation is located, and also where the spiritual energy is most turbulent.

Ordinary disciples of the demonic sects dare not approach.

As the saying goes, the most dangerous place is the safest place. Lin Feng only wants to be undisturbed, and the center of Sighing City perfectly meets his requirements.

Looking towards the center of Sighing City, Lin Feng said calmly.

"Looks like this is the only place we can go."

"However, the spiritual energy here is extremely violent, and I'm afraid I can't withstand it on my own. I'll need the little Pixiu's help."

Lin Feng was always extremely cautious. He knew that his cultivation level had not yet reached the Nascent Soul stage and he could not withstand the violent spiritual energy within the Sighing City. Therefore, he summoned the little Pixiu and used its divine power to stabilize himself.

"Little one, you've had a tough time."

The little Pixiu followed Lin Feng with almost no danger and was always able to devour large amounts of pure spiritual energy. It never felt tired and instead happily perched on Lin Feng's shoulder, squinting its eyes to enjoy the experience.

"Eeya!"

With the help of the little Pixiu, Lin Feng quickly stabilized himself.

Although the violent spiritual energy in the center of Sighing City was exaggerated, with the help of the little Pixiu, it did not have a significant impact on Lin Feng, and he still entered the center of Sighing City very steadily.

A dense spiritual energy surrounded Lin Feng, continuously eroding every inch of his skin.

Without further hesitation, Lin Feng immediately took out the jade pendant and used its power to frantically convert spiritual energy, then channeled it into his dantian.

At this moment, Lin Feng's golden core began to absorb spiritual energy frantically, like a giant vortex.

As the spiritual energy accumulated to a certain limit, Lin Feng felt that his golden core was full. He immediately circulated his cultivation technique to gradually compact the spiritual energy within the golden core.

"boom!"

With a booming sound coming from within Lin Feng's golden core, Lin Feng's cultivation broke through once again, clearly reaching the seventh level of the golden core.
