Lu Changsheng left World Heart City and once again urged the Water Mansion to continue on his journey.

Eight months later, Lu Changsheng arrived at the headquarters of the Secret Alliance, the Secret City!

Along the way, Lu Changsheng didn't encounter any trouble.

Lu Changsheng saw the Secret City in the distance and a trace of astonishment appeared on his face.

He had just scanned it with his consciousness.

Surprisingly, there was nothing there.

But Lu Changsheng could clearly see a huge city ahead with his naked eye.

Evidently, this Secret City was very peculiar.

It could only be seen with the naked eye.

As for other senses, nothing could be sensed at all.

Lu Changsheng changed his height and appearance.

He even altered his aura.

He transformed into a powerful physical entity at the Ancestor Realm level.

However, this aura was only at the pinnacle Ancestor Realm level and did not reach the Strongest Ancestor Realm.

The Secret Alliance does not restrict ordinary Ancestor Realm individuals from joining.

Lu Changsheng naturally didn't need to be too ostentatious.

Everyone who enters the Secret Alliance hides their identity and is extremely low-key.

Lu Changsheng flew towards the Secret City.

At the entrance of this Secret City, there was only one gate.

And there were also guards at the gate.

Lu Changsheng slightly sensed, and unexpectedly, the guards were also at the pinnacle Ancestor Realm level.

When entering through the gate, Lu Changsheng emitted only a trace of Ancestor Realm aura, which was equivalent to being recognized.

Then, the guards gave Lu Changsheng a mask.

The mask was called the Thousand Illusion Mask.

Once worn, it could conceal all auras, and no one could see through it.

The appearance could also transform into myriad forms, at one's will.

Even changing one's fate posed no issues.

It truly was quite magical.

However, this Thousand Illusion Mask must be returned to the Secret City upon departure.

Lu Changsheng put on the mask and continually changed his appearance.

Although Lu Changsheng's physical body could also change appearance, the Thousand Illusion Mask undoubtedly made it more convenient.

Lu Changsheng smoothly entered the Secret City.

Upon entering the Secret City, Lu Changsheng was shocked by the bustling scene before his eyes.

In Lu Changsheng's imagination, an alliance where everyone hides their identities should be a place full of filth, with everyone being extremely cautious and insidious.

But the situation within the Secret City was completely different.

It was extremely prosperous. 𝒇𝙧𝙚𝓮𝙬𝙚𝓫𝒏𝓸𝓿𝓮𝒍.𝓬𝙤𝓶

More prosperous than any place Lu Changsheng had ever seen.

Moreover, the things being sold were done so unrestrainedly.

No one ever inquired about the origins of items.

They simply focused on the transaction.

Not only were treasures sold, but there were also some employment tasks.

Very straightforward, hiring experts to kill certain powerful figures, etc.

Even hiring experts to annihilate certain factions, etc.

Many tasks were even targeted at the Strongest Ancestor Realm.

"This really... opens one's eyes."

Lu Changsheng murmured softly.

So bold, so prosperous, so unrestrained.

But upon careful thought, it was actually reasonable.

Precisely because in the Secret City everyone hides their identity, no one knows who the other person is.

So, does anyone have any apprehensions about trading?

There simply is not a shred of apprehension.

The level of prosperity in this Secret City probably surpasses the combined forces of the Ascension Alliance, the Strongest Holy Temple, and the Heavenly Realm Association.

This is the advantage of the Secret City.

However, in the Secret City, the hard currency remains the Dao fragments.

Lu Changsheng even saw celestial items.

But the selling price was as high as hundreds of Dao fragments.

This was simply akin to robbery...

No, even robbery wouldn't yield this much.

But rarity determines value.

Perhaps, there truly are people in urgent need of celestial items?

In World Heart City, the Ancestor Realm individuals Lu Changsheng saw were merely offering ten Dao fragments to acquire celestial items.

Just that no one was willing to trade.

As long as you desire it, there is nothing that cannot be obtained in the Secret City.

At this moment, Lu Changsheng truly felt a yearning.

But he was too poor.

He didn't have a single Dao fragment.

Though Lu Changsheng was honored as the master of the Sky City, in the Secret City he still felt exceedingly poor.

"How long has it been since I've experienced the feeling of 'poor'?"

Unexpectedly, now, having become the Strongest Ancestor Realm, he once again tasted the feeling of being 'poor'.

"No, I must find a way to earn Dao fragments."

"And once I've earned Dao fragments, I can't easily refine them anymore; I have to accumulate them."

"Otherwise, if I encounter some treasures I desperately need, without Dao fragments, I simply cannot obtain them..."

In his eyes, a flicker of determination appeared in Lu Changsheng's gaze.

He now had three forms of the immortal path.

Which form had the highest progress?

Naturally, it was the Physical Immortal Path.

Lu Changsheng's Physical Immortal Path had already reached a terrifying 83%.

Only an 18% increase in progress was needed to reach the pinnacle.

By then, Lu Changsheng could even attempt to challenge the Immortal Realm.

However, the progress at 83% seemed to have stagnated.

Even refining some bloodlines or powerful beings didn't seem useful.

Lu Changsheng had almost realized that only by refining true Immortal Realm-level flesh and blood could the progress be raised.

However, apart from the Kui Ox Corpse, where could Immortal Realm level flesh be found?

Previously, Lu Changsheng thought there was no chance.

But now, after coming into contact with the Secret City, Lu Changsheng felt there was a chance.

As long as there were Dao fragments, enough Dao fragments.

Within the Secret Alliance, one might find Immortal Realm level flesh.

But how does one earn Dao fragments?

This is a challenge.

The Heavenly Ancestor in the past likely relied on Sky City to gradually earn Dao fragments bit by bit.

Such a method indeed can earn a certain amount of Dao fragments.

However, perhaps it requires a long time, needing to accumulate slowly.

And even the Heavenly Ancestor did not accumulate many Dao fragments in the end.
