Tracing back to the source, Boundary Sea Worlds are collectively referred to as the Primordial World, originating from an Origin Ancestral Land, and the Great World is one of them.

Lin Moyu had seen many Boundary Sea Worlds and had even destroyed and refined them himself, so he knew there were immense differences between every world.

This wasn't just about differences in rank, but rather that even within the same rank, there could be huge discrepancies.

The Great World was extremely dominant among Boundary Sea Worlds of the same rank.

This showed that even when the Great World was still in its Primordial World state, it was already extremely powerful and possessed a profound foundation.

Lin Moyu didn't know where the Primordial World came from, but he believed it must have an origin and couldn't have just appeared out of thin air.

Perhaps he would only understand this question once he entered that Origin Ancestral Land.

Lin Moyu had now become a Dao Venerable, and he was also the Son of Taiyin.

According to the Third Ancestor, when the Origin Ancestral Land opened, he would definitely have a spot.

As for when the Origin Ancestral Land would open, no one could say for sure; they could only wait.

Since that was the case, Lin Moyu was not in a hurry and waited patiently.

Little Three was still struggling to search its bloodline memories. Unlike the Human Emperor, who had mastered all information once it was organized and could access it whenever needed, Little Three's bloodline memories could only be found when it made the effort to search for the corresponding parts.

Under normal circumstances, these memories would not reveal themselves at all.

There was a huge difference between the two.

Lin Moyu didn't know what it was searching for, but seeing it flushed bright red all over, it seemed to be struggling quite a bit.

Lin Moyu sipped his tea slowly, watching Little Three, who was flushed red all over. Little Three's appearance looked a bit like it was constipated, which was quite amusing.

A moment later, accompanied by a soft sound, a ball of blood Mist exploded.

Little Three was covered in blood, turning into a blood mouse.

Little Three's state was strange at this moment; its aura was much weaker than before, and it had actually suffered significant injuries.

To suffer heavy injuries just from searching one's own bloodline memories was truly unique.

Lin Moyu waved his hand, enveloping Little Three in a wave of Power of Life, and asked, "What are you doing?"

Little Three said, "I was searching my bloodline memories. Master, you have six Great Daos, right? In my bloodline memories, there seem to be some related memories."

Lin Moyu raised an eyebrow slightly. "Did you find them?"

Little Three said, "I found them."

Under the healing of the Power of Life, Little Three's injuries recovered rapidly.

Little Three hopped over to Lin Moyu's side, poured itself a cup of tea, and finished it in one gulp.

After drinking three cups in a row, it let out a long sigh of relief. "Master, you must not comprehend the Dao of Karma anymore."

Lin Moyu looked at Little Three, signaling it to continue.

Little Three continued, "The more Great Daos you comprehend, the more difficult cultivation becomes, and the slower your progress will be."

"In ancient cultivation methods, it seems you need to condense Dao Patterns. The more Great Daos you have, the more Dao Patterns you can condense, and the more time-consuming it becomes."

"In my memories, there is a limit to the number of Great Daos one can comprehend, and that limit is six."

"Once you exceed six Great Daos, you will be suppressed by the power of the Great Dao, and your cultivation speed will drop by at least a hundredfold."

"It seems that because the Great Dao does not allow individuals who are too heaven-defying to appear, it suppresses them."

Little Three recounted all the memories it had found.

It sounded very mysterious, but it also made some sense.

After listening, Lin Moyu pondered for a moment. "Is there no way to break this?"

Little Three shook its head. "Not in the bloodline memories. In those memories, there was once a guy who was a top-tier genius."

"Back then, my ancestor once acknowledged him as master, believing that he could not only step into the Great Dao but also become a Dao Lord."

"When one person attains the Dao, their chickens and dogs ascend to heaven; our ancestor could also benefit from this, enter the Great Dao, and attain eternal life."

"In this way, our entire clan would benefit."

"However, when that person reached the Dao Venerable 6th Realm, he comprehended the seventh Great Dao."

"From then on, he was stuck at the Dao Venerable 6th Realm and never advanced another step."

"He finally told our ancestor not to comprehend the seventh Great Dao, as the Great Dao would impose a punishment."

"Master, you must not take this lightly; you truly cannot comprehend the seventh Great Dao."

Little Three spoke with great solemnity, and Lin Moyu naturally would not take it lightly.

Lin Moyu pondered, "I believe that nothing is absolute. Any heaven-defying matter has a heaven-defying method to break it."

"Even if the Great Dao imposes a punishment, it is impossible that there is no way to break it; the Great Dao must leave a glimmer of hope."

"However, rest assured, before I find a way to break it, I will not comprehend the seventh Great Dao. Six Great Daos are enough for now."

"Perhaps one day when I become a Dao Lord, I can also let you ascend to heaven."

Little Three immediately knelt before Lin Moyu, buttering him up. "Then Little Three will definitely cling tightly to Master's thigh. Wherever Master points, Little Three will go; I will absolutely not have any disloyal thoughts."

Lin Moyu looked at Little Three with a smile. "You are quite realistic."

Little Three said brazenly, "Those who know the times are outstanding; a mouse as smart as Little Three naturally knows what to do."

Lin Moyu said, "With this lecture on the Dao, you should be close to advancing, right?"

Little Three nodded its mouse head. "Soon. I estimate that in a year or two, I will be able to advance to the Dao Venerable 4th Realm. Master's lecture is too useful; otherwise, it would have taken at least another thousand years to advance."

Lin Moyu said, "After reaching the Dao Venerable 4th Realm, go out and search for origin spirit veins to help improve the spirit veins of Yudao City. When you reach the Dao Venerable 4th Realm, I will give you a gift."

Little Three nodded its head. "Please rest assured, Master, Little Three will definitely do its best."

While drinking tea, Lin Moyu communicated with the Human Emperor through his consciousness. "Human Emperor, what do you think about what Little Three said?"

The Human Emperor said, "There are no related records in the current data."

Lin Moyu knew that what Little Three spoke of must be extremely ancient.

The Heaven-Swallowing Mouse race had existed since prehistoric times, and their bloodline memories had been passed down to the present.

Therefore, what Little Three said likely happened in prehistoric times, and it was impossible for the Human Emperor to have this information.

Lin Moyu thought to himself, "Perhaps I can ask the Third Ancestor, but I can't ask directly; I must ask indirectly."

"The Third Ancestor, that old guy, is deep in thought and difficult to deal with."

"I must take what Little Three said seriously. Before finding a solution, I cannot comprehend any new Great Daos."

Mist took Little Five around Yudao City for most of the day and ran back with a pile of snacks.

When she ran through the door, her mouth was stuffed with snacks, and Little Five's mouth was too. Although Little Yue didn't have any, she had obviously just finished eating and hadn't wiped her mouth clean yet.

Seeing the smile on Little Five's face, Lin Moyu knew they must have had a good time.

In the following days, Little Five became familiar with everyone and was no longer reserved.

Five days later, Lin Moyu looked at Little Five and said, "Little Five, can you reveal your Dao of Karma?"

Little Five thought for a moment. "In our bloodline, it's not called the Dao of Karma; it's called Planting Fruits to Obtain Cause."

Lin Moyu asked, "You cannot plant fruits now, so you have no way to demonstrate its abilities, right?"

Little Five said, "It's not entirely impossible. Little Five will try."

Lin Moyu said, "Don't force it!"

Little Five shook her head. "It's not a strain."

She raised her hand, palm facing up, and a glimmer of light appeared on her palm.

The light continued to flicker like a flame, and at the same time, a peculiar aura of the Great Dao permeated from the flame.

Little Five explained, "This is the predecessor of the fruit. We call it Fruit Fire. Little Five can only do this much for now and cannot truly plant the fruit."

Lin Moyu felt the aura of the Fruit Fire and said after a moment, "Little Five, that's enough!"

Little Five immediately withdrew the Fruit Fire. Her little face was somewhat pale; clearly, that short moment had already consumed a lot of energy.

However, she still said, "Father, do you want to do it again?"

Lin Moyu waved his hand. "No need. This is enough. Go play."

In the blink of an eye, ten days had passed since Little Five arrived in Yudao City.

Little Five had grown fond of Yudao City and played happily with Mist and Little Yue every day.

Little Five's personality was more steady than Mist's, and she would cultivate with Little Yue every day.

She was very serious when cultivating; even if Mist called her to play, she would not go.

Little Yue was digesting the Dao that Lin Moyu had lectured on every day. Her progress was rapid, and she was getting closer and closer to the Other Shore Realm, with the possibility of breaking through at any time.

Lin Moyu had been pondering the Dao of Karma for the past few days. Although he would not comprehend the seventh Great Dao anymore, it did not hinder his contemplation.

Unfortunately, after several days of thinking, there was no gain at all.

Although Little Five had displayed the Fruit Fire, it did indeed contain the aura of the Dao of Karma, but this aura was similar to that in the causality gourd.

Just as it was impossible for Lin Moyu to comprehend the Dao of Karma through the causality gourd, it was also impossible to comprehend the Dao of Karma through the Fruit Fire displayed by Little Five.

If the Dao of Karma were so easy to comprehend, Little Three wouldn't have said that no one had ever comprehended it before.

Being a similarly illusory Great Dao, the Dao of Karma was even more mysterious than the Great Dao of Luck.

While pondering, Lin Moyu also did not stop condensing the twenty-sixth Dao Pattern.

The twenty-fifth Dao Pattern was currently still vacant; Lin Moyu had not fused it with any spell.

On the twelfth day of Little Five's arrival in Yudao City, the Human Emperor suddenly sent a message of consciousness, "World Lord, an old friend of yours has arrived."

Lin Moyu's gaze looked out through Yudao City, and he saw the visitor. "Indeed, an old friend."

This "old" Lin Moyu drew out a long sound; it was indeed an "old friend."

The person who came was Dao Venerable Lu Fengqing, the white-haired Dao Venerable Lu Fengqing, who indeed looked quite old.

In fact, his age was not great, only about one hundred thousand years old, which was not considered too old among Dao Venerables.

It was just that he was always unkempt and did not care about his appearance.

He was a formation master of the Lufeng Chamber of Commerce, and his formation level had reached the seventh rank, making him a true formation grandmaster.

The formations of many branches of the Lufeng Chamber of Commerce were set up by him, but because his personality carried a bit of madness, he was also known as Lu the Madman.

There was another person who came with Dao Venerable Lu Fengqing, also an acquaintance of Lin Moyu, President Lu Xue.

President Lu Xue was previously a small manager in the Jade Sword City Chamber of Commerce; it was unknown why she had followed Dao Venerable Lu Fengqing here now.

Based on Lin Moyu's understanding of the Lufeng Chamber of Commerce, being able to return from the Southern Continent to the Eastern Continent meant President Lu Xue had been promoted.

Lin Moyu said, "Welcome them in; I will wait for them at the City Lord's Mansion."

In Yudao City, there was a City Lord's Mansion. Usually, the City Lord's Mansion had no owner, and there were only some cultivators working on cleaning duties inside.

For these cultivators in Yudao City, being able to take on cleaning work at the City Lord's Mansion was an honor.

Not only was it easy, but it could also earn a significant amount of points.

In Yudao City, points were money; one could use points to purchase or exchange for any item, and one could also use points to exchange for various items from the Human Emperor.

The entire system was similar to that in the Great World.

Lin Moyu instantly teleported to the main hall of the City Lord's Mansion through the origin spirit vein.

There were originally two people cleaning in the main hall. Suddenly, Lin Moyu appeared, and the two were startled.

Lin Moyu waved his hand. "You two should leave first; guests are coming here."

The two looked at each other, feeling at a loss for a moment.

They didn't know Lin Moyu at all, but they could feel the thick majesty emanating from him. This aura of a superior made them almost unable to catch their breath.

Lin Moyu hadn't released his aura at all; otherwise, these two little ones, who were only in the True God Realm, would have been scared to death directly.

They were at a loss for a moment. A few seconds later, one of them gathered the courage to ask, "Excuse me, which senior are you?"

Lin Moyu smiled. "Lin Moyu."

The two were stunned for a moment, then were so scared that they fell to the ground. They were somewhat incoherent. "You are the legendary City Lord Lin?"

Lin Moyu looked at their appearance, feeling somewhat helpless. With a wave of his hand, he sent the two outside.

"Human Emperor, you take command."

He had been an absentee manager for too long; there were only legends of him in the city, and very few people knew him.

The Human Emperor issued orders, letting everyone in the City Lord's Mansion withdraw, leaving no one behind.

Then he himself brought Dao Venerable Lu Fengqing and President Lu Xue into the formation.
