Sleep, as a biological behavior, mainly occurs because most life forms cannot sustain prolonged continuous movement. They consume energy during activities, and this energy can be recovered through standby waiting, which is essentially sleep.

But now, for Zhang Yanhang, who has already advanced to Fourth Tier, the spiritual energy he usually absorbs can completely replace the biological behavior of sleep to sustain his daily consumption, so naturally, he no longer needs sleep.

Moreover, after entering Fourth Tier, his body has gradually shown signs of energy quantification, effectively forming reproductive isolation with ordinary people.

Of course, this energy quantification does not refer to complete energy quantification. For life forms, the combination of matter and energy is the right path.

Thus, energy quantification here mainly refers to the disappearance of certain biological behaviors, such as breathing. Previously, Zhang Yanhang relied on his cultivation method to gradually replace food with spiritual energy and substitute water, and now he can use spiritual energy to replace oxygen.

In other words, as long as the spiritual energy in his chest remains unextinguished, Zhang Yanhang will no longer need to perform the mechanical and repetitive act of breathing, which also marks the signal of the internal spiritual energy cycle within his body.

"Thinking about not having to breathe anymore in the future suddenly feels so strange..."

Incidentally, although Zhang Yanhang currently does not need to breathe, the mechanical inertia formed by his body over twenty years still makes him involuntarily breathe automatically, which is difficult to change for now.

Luckily, this small habit doesn't need to be forcibly corrected as it's not too important. Moreover, breathing more actually has benefits, such as inhaling more spiritual energy along with air during respiration.

Additionally, after entering this internal spiritual energy circulation realm, he can actively isolate interactions with the outside world, forcibly preventing spiritual energy from escaping to the outside. In other words, he can intentionally enter a hibernation-like state to extend his survival time during the End of Dharma Era when there is no energy.

Although Zhang Yanhang has no experience in this aspect, he believes that if he truly entered complete hibernation without moving, living an extra few decades shouldn't be a problem, and cooperating with arrays and such might allow him to live even longer.

However, if spiritual qi recovery does not occur during this period, his hibernation will not be a rescue in desperation but merely drinking poison to quench thirst, ultimately leading to a dead end and wasting a great longevity.

The changes brought by this energy quantification are far more than just not needing to breathe or sleep; it also includes the modification of certain vital parts.

For instance, if his heart or spinal cord, or perhaps his neck, were destroyed, as long as the damage is not too severe, like his entire chest disappearing or the entire spinal cord being pulled out.

Generally, if his heart is merely blown up or his spinal cord is broken, such minor injuries no longer yield fatal damage like to mortals but are merely akin to cutting off a piece of ordinary muscle tissue.

Of course, the data avatar endowed upon awakeners when entering the Ashen World also has a similar function but not as powerful. Even for awakeners, the heart remains a vital part; if it's blown up, death is inevitable.

However, although post-Fourth Tier advancement leads to the disappearance of vital parts like the heart and spinal cord, if the head is blown up, he will still die. After all, at Fourth Tier, the degree of energy quantification isn't high enough, and surviving despite head explosions might require Fifth Tier or even Sixth Tier.

Regarding what state this energy quantification will eventually evolve into, Zhang Yanhang believes that the God of Scorching Sun, Crotena, whom he previously killed is a good example, since as long as divine power isn't depleted, she can instantly resurrect regardless of being torn in half or having her head blown up.

In conclusion, Zhang Yanhang truly feels the immense difference between Fourth Tier and the previous three tiers solely by relying on energy quantification. No wonder the group leader said there is a gap between Third Tier and Fourth Tier; such a huge change naturally constitutes a gap.

"After the body is energy quantified, one can directly rely on energy value to recover life value to some extent, and coincidentally, I've acquired nearly infinite energy value through Heaven and Earth Devourer, so what should I say? Does this make me an undying body?"

Of course, Zhang Yanhang currently cannot be called a true undying body; further increase in the trend of body energy quantification is necessary to seamlessly restore life value with energy value, which truly defines an undying body. As long as the enemy's damage speed cannot exceed his recovery speed, the enemy's output towards him is more or less nil.

Moreover, the benefits of body energy quantification don't end there; after energy quantification of the body, it seems to have forcefully cracked the chromosomal telomere characteristics previously limited by biological cells, leading to a surge in his lifespan.

Zhang Yanhang recollects that during the First Tier Period, his lifespan increased by only ten years; during the Second Tier Period, it normally increased by twenty years; after advancing to Third Tier, it increased by forty years. According to this developing pattern, Fourth Tier might only increase his lifespan by eighty years.

But now, relying on body energy quantification, his lifespan has directly surged by eight hundred years, twenty times the previous amount, ten times the initially anticipated lifespan.

"With the lifespan automatically increased by rank and SS-level Talent Longevity Mountain and Fortune Sea added on, I already have an extra three hundred sixty years of lifespan. Now, including the eight hundred years gained from advancing to Fourth Tier, I have a total of 1160 years of extra lifespan."

"Moreover, I am just twenty years old this year, theoretically speaking, even if I can't live to retirement, living until sixty shouldn't be a big issue, meaning I now have about a thousand two hundred years of lifespan."

Finally, Zhang Yanhang understands why others say advancing to Fourth Tier is the Immortal Land Realm, with at least a thousand eight hundred years of lifespan, as merely advancing brings eight hundred years of longevity.

Moreover, the previous three tiers granted an additional seventy years of lifespan, coupled with over a hundred years of his own lifespan, living for a thousand years really isn't an issue; even naturally short-lived individuals can live for nine hundred years.

Certainly, those capable of cultivating to this realm generally aren't short-lived; if there were no Ashen World and only normal cultivation, short-lived individuals wouldn't reach this realm before prematurely dying of old age.

As for why my own lifespan exceeds a hundred years, naturally, it's because ordinary people can live to be a hundred twenty years old, let alone awakeners with strong bodies; merely the advantage in physical quality ensures living over a century shouldn't be a problem.

"As per my current lifespan of one thousand two hundred years, I could have lived from the Tang Dynasty in AD 800 to the twenty-first century."

Speaking of which, Zhang Yanhang suddenly remembered a question. Since even he could live from the Tang Dynasty to the present, with the modern Spiritual Qi Recovery, could it be possible that some ancient freaks from the Tang Dynasty also resurrected together?

Well, such things have little to do with him. After all, no matter how much of an old monster they might be, it's unlikely they'll suddenly come and kill him for no reason, right? After all, there's no enmity and no benefit.

"Speaking of which, no wonder high-level powerhouses have long lifespans but find it hard to produce offspring. With their bodies energy-quantified, they're directly reproductively isolated from ordinary people. Even if they have twelve hundred years, what's the use? If you can't have children, then you just can't have them."

Of course, in Zhang Yanhang's current situation, if he truly wants to reproduce, it's not entirely impossible. He can still have children with other Awakeners whose bodies are also energy-quantified, like the group leader who's also Fourth Tier, for example.

"But I've barely met the group leader a few times, and I've only known them for a month or so. How would it suddenly develop to the point of having children so quickly?"

Moreover, most importantly, Zhang Yanhang doesn't want to have children. He has always been a solitary Awakened who firmly walks the path of Self-Immortality. He has always believed that as long as his life span is long enough, he doesn't need to have children.

After all, it's just like a certain super long-lived old lady and a certain 'Prince of Seventy Years' old man. He worries that his descendants might not live as long as he does. This is indeed very likely, as he doesn't believe his descendants' Talent would be stronger than his. That's unrealistic.

He feels that in his current situation, if he truly passed down his bloodline, then in terms of specifications, it would certainly belong to those extremely powerful ancestral bloodlines of ancient times. Descendants wanting to be stronger than him could only be dreamt of.

Of course, most importantly, even all the above aren't all the benefits brought to him after the promotion to Fourth Tier body energy-quantification.

In fact, just now, Zhang Yanhang has already discovered a quite useful ability brought by the body energy-quantification. He discovered that he seems to have gradually shaken off the limitation of gravity.

Zhang Yanhang controlled his body to levitate slowly, but during this process, he didn't expend any energy; everything was so natural.

It was as if he suddenly gained an innate instinct, allowing him to a certain extent to break free from gravity to achieve energy-free flight and levitation.

Of course, this basic state has a relatively slow flying speed. To achieve a Movement Speed like his own, energy is needed for acceleration.

However, no matter how you look at it, getting a flying ability for free, and a constant flying ability at that, Zhang Yanhang is still very happy.

This flying ability won't be forcibly removed like the Flying Technique through spell capabilities, nor will it have a time limit. It even can resist most Fly-Prohibition Abilities, since the flying principle is completely different from normal flying techniques.

To give an example, your Fly-Prohibition Barrier can force a bird from the sky to the ground, but can you force the clouds floating in the sky down?

For this reason, Zhang Yanhang is genuinely quite happy to have gained such a constant flying ability for free upon the Fourth Tier promotion, as his original Flying Technique was indeed low in Magic Strength, merely a weak Third Tier Magic with limited potential and high energy consumption.

But now this constant flying ability acquired at Fourth Tier not only has low energy consumption but also allows for faster flying speed, indeed serving as a perfect superior substitute.

As for why these transformations must be obtained through Cultivation Method rather than just with rank promotion, that's naturally due to different Power Systems.

Rank merely represents an energy level; various Power Systems can be integrated into it. For instance, a Fourth Tier demon flying with wings, a Fourth Tier Wind Element Lord naturally capable of flying, and a Fourth Tier Mechanical Life using booster engines for flight.

Rank here is just a measure of strength, unrelated to one's Power System. Although they all gained flying abilities, the related flying principles are entirely different, with not a single similarity.

To provide an example, if Zhang Yanhang were to cultivate a Body system's Cross Training Technique now, like the Eight-Nine Mysterious Skill of the famous Erlang God, such body energy-quantification characteristics wouldn't appear.

This body energy-quantification is a trait of the Limitless Universe Skill itself, a characteristic of the Awakener's Power System, or you could say a trait of the Imperial System's Awakener.

Other nations will also have their unique traits. After all, what's cultivated differs. Foreign countries generally don't have Cultivation Techniques but use Breathing Methods or Meditation Methods. Naturally, different techniques cultivated yield different results.

It is precisely because of this that Zhang Yanhang had to wait until advancing the Limitless Universe Skill to Fourth Tier to acquire these abilities, as they aren't genuinely rank abilities, but rather Cultivation Method abilities unlocked at that rank.

In other words, his promotion to Fourth Tier, although it led to a leap in Life Rank, didn't cause significant changes due to being merely a straight rank promotion. The real changes are responsibilities of the relevant Power System.

After considering all the abilities acquired due to body energy-quantification after advancing the Limitless Universe Skill to Fourth Tier, Zhang Yanhang is truly filled with emotion.

"The Immortal Land Realm truly lives up to its name. Just in promotion, one gains a life span of a thousand years, coupled with constant flying abilities and, after body energy-quantification, no need for sleep, breathing, drinking, or eating, along with disappearing vital points; even if the heart is removed, it's as if nothing happened.

In this way, it's no wonder that ancient people regarded Fourth Tier cultivators as deities. This realm indeed bears no difference from being gods."

Of course, after promotion to Fourth Tier, Zhang Yanhang also gained enhancements in energy control abilities. This is a fundamental reinforcement, albeit not as crucial for Zhang Yanhang, who doesn't often utilize energy attacks in daily combat.

But this does mean that post-Fourth Tier promotion, relevant attack abilities for Awakener are improved too. As long as one masters the techniques, the various celestial means can be easily handled, relying on powerful destructive and survival abilities to achieve a literal 'Immortal Land.'
