Swallow the starry sky, grind to become the strongest in the universe

Chapter 61 The Advance Payment of the Book of Cause and Effect, the Explosive Speed ​​of Progress
"boom!"

The power of blazing light and the fundamental laws of time converged and spread out from the Time Sword in Duan's palm.

In an instant, a long, narrow, and sharp platinum-gold sword, about ten meters long, materialized.

On the longsword, countless intricate silver threads intertwine and spread, connecting with each other to form a complete and complex pattern on both sides of the blade.

The secret patterns on one side of the sword are complex blazing sun totems, while the secret patterns on the other side are deep crescent moon totems. The sun and moon totems intertwine and rotate, radiating extremely sharp law fluctuations.

"Hey!"

As Yu Duan wielded the Sword of Time, ripples spread through the surrounding space and time, creating a sense of oppression, as if the blade had carved a ripple across the river of time.

The fourth level of the Time Sword Technique – The Revolving Sun and Moon!
This level of understanding requires an extremely high level of comprehension of the laws of light and time.

In recent years, Yu Duan has focused his energy on comprehending the fundamental law of time. Although his understanding of the fundamental law of light has improved, it is not significant.

The reason Yu Duan was able to unleash this level of sword technique was because his mastery of the laws of time far exceeded the requirements of the fourth level of sword technique, and he was able to execute it due to the balance between the two.

However, Yu Duan's attention was not on the fourth level of the incredibly powerful Time Sword Technique at this moment.

Within the sea of ​​consciousness, the life core, covered with colorful patterns, floats silently.

Within the core of life, the originally gentle and radiant rosy clouds on the Book of Cause and Effect suddenly blazed brightly at this moment.

The progress bar text on the book page disappeared as Yu Duan unleashed the fourth level of sword technique, and all of Yu Duan's insight options reappeared.

[The Fundamental Law of Time] Progress of Comprehension: Master the essence of the first 5 laws of time. You can advance your comprehension of the 6th essence of time, but the cost is 1.53 years to comprehend the fundamental law of time.

[Time and Space Sword Technique] Top-tier basic secret technique, level: fourth level, entry-level. Can pre-grant insights into the fifth level, entry-level. Cost: 8216.42 full-power executions of this sword technique.

【Time Flows】Top-tier movement technique, level: Second stage of Time Flows. Can be used to advance the understanding and attainment of the 'Third stage of Time Flows' to repay the price, and can move a distance of 1.214 light-years when fully unleashed.

[Chaos Stele of the Myriad Universe] Comprehension Progress: First Diagram, Minor Success. You can advance your comprehension to the 'Greater Success, Perfection' level of the first diagram to repay the price and continue studying the Chaos Stele for 67 days.

……

"The progress bar has been completely cleared!"

Yu Duan originally wanted to try using the fourth level of swordsmanship to advance the progress bar of the third level, to see if it would greatly improve efficiency.

However, unexpectedly, the progress bar was reset to zero. The progress bar for practicing the third level of the Time Sword more than 14 million times was completely removed, and it was no longer possible to continue practicing.

"So there's a hidden mechanism for paying the price, but it's not easy to trigger."

To trigger this mechanism, you must master a higher level of arcane arts before completing the progress bar.

This time, it was because of the enlightenment gained from comprehending the Chaos Stele that this hidden mechanism was triggered after more than ten years of accumulated knowledge.

"Is it about pre-drawing the fifth level of the Time Sword Technique, or pre-drawing the essential understanding of the sixth time law?"

As for the option to study the Chaos Stele for 67 days, Yu Duan completely ignored it.

Are you kidding me? Where would you get 67 days to meditate? That would require 10 opportunities for enlightenment.

“Normally, to unleash the fifth level of the Sword of Time, if one’s mastery of the Law of Light is insufficient and one relies solely on the mastery of the Law of Time Origin, one needs to comprehend the profound essence of the first 12 laws of time.”

"Among them are 9 of the most basic law essences and 3 of the medium-difficulty law essences."

According to the Book of Cause and Effect, it would take Yu Duan a little over a year and a half to grasp the most basic essence of the laws of time.

To truly grasp the essence of a moderately difficult time law requires at least 10 times the time of a moderately difficult one.

"I grasped the essence of the first law three months after the Genius Battle ended. It took me more than a year to master the essence of the second law of time."

"As for the essence of the third law of time, although I have gained some understanding, the mysteries I have come to understand have many problems and are not pure enough."

Of the first nine most basic laws of time, the first one is the most difficult to grasp. Once you truly understand the basics, the subsequent eight basic laws become easier to comprehend with increasing speed. (Note: Refer to Chapter 34 of Part 8 of the original work.)
"Judging from this rate of progress, the cost of repaying the essence of the time law in advance is calculated based on the comprehension efficiency of the original universe." "With the bonus from the initial universe, it should be ten times faster."

Yu Duan's mind raced, and he instantly determined which was more efficient.

To master the fifth level of swordsmanship, one needs to practice more than 8000 million times with full effort. Even if a method to improve efficiency is found, it would probably take decades or even centuries.

This takes too long, and practicing the Time Sword Technique in Chaos City all the time would be a waste of those 30 years of study.

"Pre-emptively drawing upon the essence of the sixth fundamental law of time!"

As Yu Duan's thoughts stirred, the Book of Cause and Effect trembled, and a dazzling light enveloped the origin of his soul.

Instantly, Yu Duan's consciousness was immersed in a distant and profound dream.

In this dream world, Yu Duan enters a perfect state to comprehend the fundamental laws of time.

The so-called perfect state is to bring one's comprehension and will to their absolute peak and optimal state, and then use this perfect state to comprehend the profound mystery of the sixth nature of time for more than a year and a half.

This state is practically impossible to achieve. As long as you are human, your state will fluctuate, and it is impossible to maintain a perfect state all the time.

After a moment, the radiant glow emanating from the Book of Cause and Effect gradually dimmed, no longer intense, and transformed into a soft halo surrounding the Book of Cause and Effect.

At this point, all the options on the Book of Cause and Effect disappeared, leaving only a progress bar for repaying the advance payment.

"Repaying the advance cost, comprehending the fundamental law of time for 1.53 years. Current progress: 1 minute and 12 seconds..."

At this moment, Yu Duan was still immersed in his comprehension of the laws of time, and the progress bar of the Book of Cause and Effect was also jumping.

Every 10 seconds, the pre-allocated progress increases by 102 seconds, making the efficiency more than ten times higher.

At this rate, it would only take less than two months for Yu Duan to be able to start making advance payments again.

To grasp the most basic essence of a law in two months is a much faster rate of progress than Luo Feng, who had just entered the Domain Lord level.

"I don't know how much slower I am than Koti in terms of my current rate of progress."

A silvery-white glint flashed in Yu Duan's eyes.

This is just a simple improvement from the Book of Cause and Effect; I am also comprehending the mysteries of the laws of time.

Although my own rate of progress cannot compare with the speed of the absolutely perfect state when the Book of Cause and Effect provided a preview.

However, the combined progress from both will be much faster.

"Naturally, has Koti completed the Sky Bridge?"

As soon as Yu Duan finished speaking, the AI ​​assistant's natural form was projected onto his shoulder.

“Master, just four minutes ago, Koti passed through the fifth level of the Sky Bridge.”

Upon hearing this, Yu Duan shook his head helplessly: "It seems that it will be difficult to surpass it in the short term."

"The fifth level of the Bridge to Heaven. Kodi's progress over the past three years, coupled with his comprehension of the Chaos Stele, is truly astonishing."

Yu Duan was mentally prepared for the rapid progress of Kodi.

After all, it only took him three years to catch up with his nearly 20 years of arduous practice and enlightenment.

Now, nearly three years have passed since the end of the Genius Battle, and it has been a three-year period of intensive training at a cosmic level, so it is normal for the speed of progress to be even more astonishing.

"Come on, let me see how many levels I can pass through on the Bridge to Heaven."
