**Chapter 1821: He Won't Die in There, Will He?**
Lin Moyu had no idea how long he had been cultivating in the Mysterious Iron Secret Realm.
Time had lost all meaning.
He continued tirelessly, repeating the monotonous process over and over again.
The progress of his physical body was very slow, but fortunately it never stopped, constantly improving bit by bit.
This was the nature of cultivation - it wasn't about who could go the fastest, but who could persevere to the end and go the farthest.
The God King Golden Body, which could initially only last for 3 seconds, could now endure for 30 seconds - a tenfold increase.
After the God King Golden Body collapsed, it now took several minutes for the vibrations of the iron powder to grind his physical body to pieces.
His physical body had advanced from the second stage of the God King realm to the fourth stage.
The cycles were getting longer and longer, but the effects were diminishing.
Lin Moyu knew it was time to go deeper.
He could sense that deeper within the iron powder red clouds, there was an even more magnificent power, with more intense vibrations.
These vibrations were like knives and swords, rubbing and cutting at his physical body.
As long as he could withstand it, he could continue cultivating.
Until these vibrations could no longer harm his body, that would be the limit.
Lin Moyu began to go deeper, flying towards the depths of the red clouds.
Countless iron powder particles flew over, surrounding Lin Moyu and vibrating violently.
As they vibrated, they made a sound like metal scraping against metal.
Lin Moyu didn't know how deep the iron powder red clouds went. He only knew that after advancing several thousand meters, the vibrations of the iron powder intensified.
Numerous wounds reappeared on his skin, and his bones ached with pain.
Lin Moyu stopped, slowly took a breath, and inhaled some iron powder, giving himself a taste of both ice and fire.
His face was quickly covered in blood, as was his body, turning him back into a bloody figure.
But beneath the blood, his eyes were exceptionally clear and spirited.
Lin Moyu looked into the depths of the red clouds, where a red flame was burning.
The red flame vibrated extremely violently, over a million times per second.
As it flickered, it continuously released a special energy, like rules, constraining countless iron powder particles within a certain area.
It also caused these iron powder particles to vibrate continuously like itself.
There were quite a few such red flames in the iron powder red clouds.
"This red flame is probably not the core."
"There should be something else at the core."
Through the Eye of the Soul, Lin Moyu saw ancient runes contained within the red flame.
At the same time, inside it there was also mysterious iron essence, which served as fuel for the red flame.
Lin Moyu's mind was clear as a mirror, knowing his next goal.
When the iron powder here lost its effect, he would seek out the red flames, let them burn him, and continue cultivating his physical body using the red flames.
Having found a way to continue improving, Lin Moyu was in high spirits.
Just as his physical body was about to collapse, white light flickered, and abundant life force appeared, healing his body.
Then another cycle began anew.
Here, the cutting force of the iron powder's vibrations had increased, the cycles were shorter, and efficiency had improved.
But compared to the initial cycles of ten-odd seconds, it was still several times slower.
Lin Moyu wasn't in a hurry. Throughout his journey, he had deeply understood one principle:
Steady and sure, each step must be taken firmly.
Outside the secret realm, a group of God Kings were full of doubts.
"Lin Moyu has been in the secret realm for almost 30 days now, why hasn't he come out yet?"
"Yeah, if it was just to complete the task, two or three days would be enough. If it's for body refining, it would be slower, but normally it would only take ten to fifteen days."
"Could he be continuously refining his body in there?"
"Is there another possibility - that he died in there?"
"Impossible, with his strength, he couldn't possibly die in there."
"You can't say for sure. What if he encountered the red flames inside?"
"Exactly, even God Sovereigns have to retreat when facing the red flames. With bad luck, they could die too."
Everyone felt confused. After Lin Moyu entered the secret realm, there had been no movement from him.
Thus, all kinds of speculations were born.
Some thought Lin Moyu was continuously refining his body in the secret realm, while others believed Lin Moyu had already died inside.
However, regardless of the speculation, there was no actual evidence.
Days passed one by one, and in the blink of an eye, 50 days had passed since Lin Moyu entered the secret realm.
According to the records of the Mysterious Iron Secret Realm, the longest anyone had spent body refining inside was 48 days. Lin Moyu had already broken that record.
However, everything would have to wait until Lin Moyu came out to be confirmed. If Lin Moyu had really died inside, this record wouldn't count.
In the secret realm, sharp friction sounds constantly emanated from within the iron powder red clouds.
It sounded as if countless knives were cutting something.
The sound of metal friction was unpleasant, but Lin Moyu, as the source of the sound, paid no attention to it.
"Finally reached the limit."
The iron powder could no longer cause him any harm.
Whether it was his skin, flesh, bones, or internal organs, the iron powder had lost its effect.
His physical body had officially reached the sixth stage of the God King realm. At this level, his physical body was comparable to many peak God Sovereigns.
Only those at the Other Shore realm would have physical bodies surpassing Lin Moyu's.
Body refining with iron powder had reached its limit; the next step was body refining with red flames.
Lin Moyu calculated the time - he had been in the secret realm for exactly fifty days.
Advancing four stages in fifty days - if people knew this speed, it would definitely scare a large number of them to death.
Others here might need half a day for each cycle, spending most of the time recovering their physical bodies.
Unlike him, who initially completed a cycle in just over ten seconds.
The difference between ten-odd seconds and half a day was over a thousand times.
His fifty days were equivalent to several hundred years for others.
Moreover, as the efficiency of the iron powder decreased later on and each cycle took longer, for others, the time would increase exponentially, making the gap even larger.
And the level of danger was not even in the same league.
For others, one moment of lost control could mean death and destruction of their Dao.
If calculated carefully, his gains in fifty days were more than what others would gain in a thousand years.
In a thousand years, as long as one's talent wasn't poor, they could cultivate from the first stage of the God King realm to the ninth stage.
And the danger was so high.
Body refining was far more difficult than soul cultivation.
Lin Moyu took a deep breath, inhaling a large amount of iron powder. Immediately, intense friction sounds resonated inside his body.
He then exhaled all the iron powder and looked towards the red flames thousands of meters away.
"I hope you won't disappoint me!"
Arriving in front of the red flames, he reached out to touch them.
The God King Golden Body only lasted one second before completely collapsing. The strength of the red flames far exceeded Lin Moyu's imagination.
The red flames jumped violently, like knives, instantly drilling into his fingers.
Carrying intense vibrations, they penetrated his skin and flesh, entered his bones, and then his internal organs.
They integrated into every inch of his body in an instant.
An intense burning sensation swept through his entire body, and Lin Moyu instantly became a man of fire.
Lin Moyu's entire body was vibrating violently; at this moment, he had become a second red flame.
Under the intense high temperature and terrifying vibrations, countless cracks appeared on Lin Moyu's body, but no blood flowed out - all the blood had been dried up.
In just three seconds, his physical body had already reached its limit and was about to collapse.
White light shone, and abundant life force flowed throughout his body.
"It's different from before."
"It can't be dispersed!"
Lin Moyu was shocked in his heart. The law hadn't been able to disperse the red flames immediately.
The red flames were still burning fiercely, continuing to destroy his physical body.
The Law of Undeath continuously healed his physical body, while the red flames continuously destroyed it. The two seemed to be competing in speed, seeing which was stronger and faster.
Lin Moyu wasn't panicked; there was a hint of joy in his heart. "This is better, more efficient."
He continuously drove the law, contending with the red flames.
One moment his body was cracked by the red flames, the next moment the life force healed the wounds.
The two forces used Lin Moyu's physical body as a battlefield, with the battle spreading to every corner of his physical body.
His physical body was also rapidly improving under this state.
