After an incense stick of time, Nian Huan and Jia Baihe finally understood the reason.

A new method of advancing in the Great Dao appeared in the Fog Realm, which involves purifying one's own Taoist Rhythm.

Especially many Saints stuck at the fifth step of the Great Dao, at the level of Wuque Saint, or the sixth step, at the level of True Saint, all because their own Taoist Rhythm was too mottled.

Once potential is exhausted, they can only remain at a certain level without making any progress.

If they want to advance, they must remove the mottled Taoist Rhythm from their own Great Dao.

Peeling away their own mottled Taoist Rhythm is purifying the Taoist Rhythm.

Purifying mottled Taoist Rhythm is most commonly done by Slaying the Dao.

But Slaying the Dao is too dangerous; first, the Dao Slayer must have a firm will.

If the will is not firm, there's a very likely chance they'll cut off their own Primordial Spirit while Slaying the Dao.

A firm will is just the most basic condition for Slaying the Dao.

Besides this, one also needs top tier Tao Techniques and cultivation resources.

If the Tao Techniques can't support it, and cultivation resources are insufficient, it is easy to break down one's own Tao Foundation, leaving Reincarnation as the only option.

Retaining memory after Dao-Slaying Reincarnation is extremely unlikely.

A Reincarnation where memory cannot be retained, how is it different from death and the disappearance of the Dao?

So unless absolutely necessary, Daoist Practitioners should avoid Slaying the Dao.

This gave rise to a second industry, Dao Entrustment.

Dao Entrustment involves entrusting one's mottled Taoist Rhythm to another cultivator during cultivation, thereby purifying one's own Great Dao.

Dao Entrustment is safe and reliable, and can perfectly remove one's own mottled Taoist Rhythm, making it the best way to purify the Great Dao.

Shi Changxing was severely injured while fleeing and was taken away by a Dao Entrustment building, now becoming a Dao Entrustment vessel for this building.

That is to say, as long as other cultivators enter this Dao Entrustment building for cultivation, their mottled Taoist Rhythm will be absorbed by these Dao Entrustment vessels.

A Daoist Practitioner whose Taoist Rhythm has become mottled to a certain extent has only one path left — to explode or to fall into demonic path and die.

Dao Entrustment vessels generally do not have a good end.

This is why Shi Wanrong was anxious and worried; as soon as she learned that her father Shi Changxing had become a Dao Entrustment vessel, she immediately wanted to forcibly take him away.

As a result, this Dao Entrustment building was very powerful, and she herself nearly fell into it and became a new Dao Entrustment vessel.

"These beasts." Jia Baihe stood up angrily after hearing the whole story.

She empathized deeply; in her past life, she had experienced similar things.

Although it wasn't Dao Entrustment, the mental and physical torture and humiliation weren't different from Dao Entrustment.

As for Nian Huan, she had not experienced such things; although she was angry, she didn't feel it as deeply as Jia Baihe did.

However, her character was very similar to Ding Huan's when he was young; she almost immediately said, "Let's go together, I don't believe they're that powerful."

Having practiced the Great Universe Technique to the seventh step over the years, Nian Huan has encountered many strong practitioners.

She has never been defeated, and her confidence now is overflowing.

Shi Wanrong shook her head, "The three of us probably can't do it. That City Lord Wu is very strong, and I'm not his match."

"What cultivation technique are you practicing?" Jia Baihe, with two lifetimes' experience, thought about the issue more comprehensively and calmly than Nian Huan.

From Shi Wanrong's strength, she could roughly judge how strong City Lord Wu was.

They needed to rescue Shi Changxing, but they also had to understand their own strength, and not act impulsively.

"I'm practicing the Chaos Dao Technique, seventh step of the Great Dao. I dared to move to forcibly take my father away because I know my strength; ordinary seventh step practitioners are simply not my opponents."

Shi Wanrong spoke the truth; she knew that even a slight error could not only fail to rescue her father but would also drag Nian Huan and Jia Baihe into danger.

"Is that City Lord Wu at the eighth step of the Great Dao?" Jia Baihe asked in surprise.

Shi Wanrong practiced the Chaos Dao Technique, and still was at the seventh step of the Great Dao, indicating her strength probably wasn't much weaker than Jia Baihe's.

If Shi Wanrong is not City Lord Wu's match, then it's likely Jia Baihe would also find it difficult to beat City Lord Wu.

Shi Wanrong shook her head, "I couldn't tell."

"I'll go take a look first. If it's really too strong, we'll look for Senior Di He in the World of Gods for help," Nian Huan stood up and said.

"If we go, we'll go together; Wanrong is injured, so she should stay and heal here," Jia Baihe said immediately.

How could she let Nian Huan take the risk alone?

Shi Wanrong shook her head, "It's just my Taoist Rhythm that's been corroded. Nian Huan helped remove it, and by the time we reach the Fog Realm, my injuries will surely be healed."

Having a Chaos Dao Body allows for very quick recovery from injuries.

"Then let's go together." Jia Baihe didn't say much, but having traveled alone for so many years, once she decided on something, she was very decisive.

...

Yongbian Dao City.

In terms of prosperity, this place even surpasses Ducheng in terms of population.

After all, the Chief of Ducheng, Wen Shi now didn't dare to return to Ducheng.

Because Wen Shi's fame still lingered, no one dared to proclaim themselves City Lord in Ducheng.

Even Yi Ju didn't get involved in others' matters.

He had a good relationship with Ding Huan, who wouldn't always be in Ducheng.

Who knows when Wen Shi might return?

So Ducheng remained in a state of looseness, naturally worsening over time.

Yongbian Dao City was different.

The hottest place in Yongbian Dao City was not some Trading Building or Resting Lodge, but rather Yongbian Dao Entrustment Building.

The Yongbian Dao Entrustment Building was always crowded, sometimes even requiring an appointment to enter for cultivation.

The person behind Jidao Building is the City Lord Wu Xiu of Eternity Edge City.

At this moment, there are three women standing outside Eternity Edge City.

They are the newly arrived Nian Huan, Jia Baihe, and Shi Wanrong.

Just as Shi Wanrong said, as a Chaos Dao Body, after the corrosive Dao Rhythm was stripped away, her injuries healed quickly, and now her wounds have long vanished.

"Should we sneak in with a shape-shift? Otherwise, I will be recognized very quickly," Shi Wanrong whispered.

"How would my father get in here?" Nian Huan suddenly asked.

The reason Nian Huan asked this was that she rarely went out with Ding Huan.

Shi Wanrong recalled that when Ding Huan entered the World of Gods, he directly destroyed the barrier at the entrance:

"If Senior Ding were here, he would have probably just cleaved Eternity Edge City in half with a single strike, but we..."

Before Shi Wanrong could finish speaking, she saw Nian Huan summon an enormous stone sphere...

The vast aura quickly filled the space around them.

Both Jia Baihe and Shi Wanrong were stunned. How was this a Magical Treasure?

This was simply a planet.

Not only were Jia Baihe and Shi Wanrong in a bit of shock, but the cultivators outside Eternity Edge City were also staring at Nian Huan in disbelief.

When has Eternity Edge City ever been attacked like this? Only it has hunted down others, never the other way around.

The violent Dao Rhythm exploded.

The vast stone sphere smashed down.

Boom!

The barrier of Eternity Edge City disintegrated into powder under the vast stone sphere.

The entire scene of Dao City was exposed.

Even several streets were blasted into a massive crater.

Seeing Nian Huan preparing to charge straight in, Jia Baihe didn't waste words and decisively summoned her own Magical Treasure.

She was never one to complain.

When something happens, just face it directly.

Jia Baihe's Magical Treasure is the Devouring God Halberd, which Ding Huan obtained on Blue Star Island.

Initially, it was just an Innate Treasure. After she received it, Jia Baihe upgraded it to a Heaven Creation Treasure over the years.

While Ding Huan frequently acquired Heaven Creation Treasures and Post-Chaos Supreme Treasures,

that was because Ding Huan could tear apart opponents' Tao Worlds.

Additionally, the places Ding Huan visited and the entities he slew were all of the Seventh Step of the Great Dao.

In reality, top-tier Magical Treasures are extremely rare.

The few existing top-tier Magical Treasures are mostly in the hands of those strong individuals.

So whether it's Nian Huan's vast stone sphere or Jia Baihe's Devouring God Halberd, they are both eye-catching existences.

This vast stone sphere used to belong to Jian Zhen, who later traded it to Ding Huan.

Jian Zhen, too, was an existence of the Seventh Step of the Great Dao.

How could his Magical Treasure be inferior?

"Vast stone sphere, Heaven Creation Treasure?" a slightly sharp voice rang out.

Standing in front of Nian Huan and the other two was a frail-looking man, his Taoist Rhythm surging, profound and long-lasting.

Just as Shi Wanrong said, Jia Baihe could guess this man was the City Lord of Eternity Edge City, but she couldn't discern his cultivation level.

"He is Wu Xiu, the City Lord of Eternity Edge City, and standing behind him is the Chief of Jidao Building, Yin Cang."

Shi Wanrong immediately informed Jia Baihe and Nian Huan.

Compared to Wu Xiu's frail and sinister look, Yin Cang was short and plump, resembling a ball.

Wu Xiu was not worried about Nian Huan smashing the barrier of Eternity Edge City; instead, he was pleasantly surprised looking at the vast stone sphere suspended above Nian Huan's head.

Never mind that the vast stone sphere is only a Heaven Creation Treasure, once augmented with Divine Skills, its power can rival that of a Post-Chaos Supreme Treasure.

"He is indeed at the Eighth Step of the Great Dao," Nian Huan said calmly.

Jia Baihe and Shi Wanrong couldn't see Wu Xiu's cultivation level, but she cultivated the Great Universe Technique and could see it at a glance.

Aiming for her vast stone sphere?

In her Tao World, she also has the Slaughter Dao Sword and the Nine Yuan Brush her dad gave her.

Those are all Post-Chaos Supreme Treasures, but she prefers impressive kill treasures like the vast stone sphere, so she rarely uses the Slaughter Dao Sword and the Nine Yuan Brush.

Hearing that Wu Xiu was at the Eighth Step of the Great Dao, Jia Baihe's gaze slightly tensed.

The Eighth Step of the Great Dao, she might not be able to win.

No matter what happens later, they must not let Nian Huan fall here.

"Brother Wen, which one do you fancy? Go ahead and choose," Wu Xiu didn't immediately act but instead turned to the man beside him.

This man had just arrived here as well.

Shi Wanrong recognized this person; she whispered, "The guy who just came and stood next to Wu Xiu is Wen Shi, the City Lord of Ducheng, who was once scared away by one of my seniors."

Wen Shi awkwardly smiled, regretting coming to Eternity Edge City.

You, Wu Xiu, if you want to court death, don't drag me into it, Wen Shi.

Shi Wanrong has a close relationship with Lan Xiaobu, and not only that, the woman standing next to Shi Wanrong seems to have a friend who is also Lan Xiaobu's Daoist partner.

Finally leaving Ducheng and with Lan Xiaobu not chasing him anymore.

But Wu Xiu wanted him to deal with these three women here; what, does Wen Shi have crap for brains?
