These flames felt almost identical to Lin Moyu’s own Undying Flame, only more aggressive and seemingly more powerful.

His own Undying Flame was more of a Support ability, resurrecting the dead, and did not actively attack.

They were both Undying Flame, yet they were Undying Flame of different natures.

Chapter 1416: Slaves in Bone Hell

The gray-white world of Bone Hell was shrouded in flames.

The Undying Flame from the true hell contained astonishing power.

A God King Rank 3 Wonder Spirit lasted less than a minute inside before being burned to ash.

Then, waves of pressure appeared out of thin air upon Lin Moyu.

The way this crushing pressure appeared was extremely strange; there was no prior warning, and it appeared the instant the Wonder Spirit died.

To Lin Moyu, it felt as if the Wonder Spirit's vengeful soul was retaliating against him.

Of course, this was just a feeling, and Lin Moyu had no intention of seeking its root cause.

Immense crushing pressure surged from all directions, constantly battering him.

The crushing pressure on the soul level was the weakest; in front of his peak Rank 4 Soul Barrier, this level of pressure was nothing.

The crushing pressure on the physical body was much greater. Lin Moyu sensed it; it was slightly stronger than in the tenth-floor area.

But the increase was extremely limited and still could not reach the limits of his physical body.

If he only relied on killing God King Rank 3 Wonder Spirits, the speed of improvement might be even slower than in the tenth-floor area.

After this test, Lin Moyu knew that merely killing God King Rank 3 Wonder Spirits was far from enough.

If he wanted to improve his physical body as quickly as possible, he needed to kill higher-ranked Wonder Spirits.

Bone Hell continued to flicker in the starry sky; the gray-white world seemed somewhat out of place in the pitch-black darkness, appearing extremely conspicuous.

The Wonder Spirit had just died, only to be reborn in the eerie Bone Hell.

Its form was exactly the same as before, constantly changing, with no specific shape.

It was just that its color had turned gray-white, and it was covered by a thin layer of gray flames.

Having died in Bone Hell, it became a slave of Bone Hell.

As long as Lin Moyu did not die and the hell was not destroyed, it would never be able to escape.

Even if it died again in Bone Hell, it would be reborn shortly after.

"Bone Hell seems even more powerful than I anticipated."

"And as I kill more enemies, Bone Hell will become stronger and stronger."

"It's another technique that gets stronger the more it fights."

Lin Moyu experienced the power of Bone Hell. This power was not a one-time thing but continued to grow.

But at the same time, Bone Hell's strengthening required his own effort.

It required him to constantly kill enemies and accumulate power.

"If I coordinate Bone Hell, the Undead Legion, and the Buddha Kingdom in the Palm, how powerful could the combat strength become?"

Lin Moyu pondered the tactics, while at the same time, the Skeleton Divine General brought back more Wonder Spirits.

The number of Wonder Spirits brought back this time had increased; there were four in total.

Three were God King Rank 3, and one was God King Rank 4.

Lin Moyu wanted to see if killing multiple Wonder Spirits at once would have a better stimulating effect on his physical body.

Bone Hell appeared in the void once again, enveloping the four Wonder Spirits.

Bone Hell was not only an attack method but also possessed a certain ability to trap enemies.

The four Wonder Spirits had no intelligence; they bumped around chaotically in Bone Hell and could not escape for a time.

Lin Moyu did not pay attention to the God King Rank 4 Wonder Spirit for the moment, but instead controlled the Undying Flame in the hell to directly burn the three God King Rank 3 Wonder Spirits.

The Wonder Spirits were quickly burned to death, and three waves of crushing pressure acted on Lin Moyu almost simultaneously.

Lin Moyu felt it carefully. "The three waves of crushing pressure overlap, and it has indeed increased. It seems that killing multiple Wonder Spirits at the same time can further increase the crushing pressure."

"I wonder if three God King Rank 3 Wonder Spirits can compare to one God King Rank 4 Wonder Spirit."

With a thought, the Skeleton Divine General rushed into Bone Hell, and with a sweep of sword qi, the God King Rank 4 Wonder Spirit was killed on the spot.

If he used the Undying Flame, it would take a while to burn, but using the Skeleton Divine General, he could kill it cleanly and directly.

The Skeleton Divine General had the combat strength of a God King Rank 8; the gap in cultivation realms allowed the Skeleton Divine General to have the ability to crush the Wonder Spirits.

Previously, when facing the Ancient Buddha palm print, it wasn't that the Skeleton Divine General wasn't powerful enough, but that the Ancient Buddha palm print was simply perversely strong.

The Wonder Spirit was killed, but the crushing pressure did not act on Lin Moyu.

The Skeleton Divine General felt the crushing force immediately, and its Soul Fire flickered and jumped.

Lin Moyu was somewhat surprised. "So that's how it is; those killed by the skeletons don't count towards me."

"It seems the plan needs some changes."

The Wonder Spirit's retaliation finds whoever killed it.

If the Skeleton Divine General kills it, it counts on the Skeleton Divine General, not Lin Moyu.

This change caused Lin Moyu's plan to shift. He had originally wanted to use the Skeleton Divine General to quickly kill a large number of Wonder Spirits after testing the limits of what he could withstand.

He had the advantage in numbers; whether it was searching for Wonder Spirits or killing them, he could achieve excellent control and maximize efficiency.

But now that was clearly not feasible; the Wonder Spirits killed by the Skeleton Divine General were of no help to him.

Lin Moyu quickly formulated a new strategy.

"Use the Skeleton Divine General to lure the Wonder Spirits, and then I will personally trap and kill them."

"If there are many, I can let the Starlight Lich trap them with illusions."

"I just don't know where the limit of Bone Hell is. If a slave of Bone Hell kills a Wonder Spirit, does it count towards the slave or towards me? I still need to test that."

Next, Lin Moyu conducted several more experiments.

He discovered that if he used a slave in Bone Hell to kill a Wonder Spirit, the retaliation would also fall upon him.

The combat strength of the slaves in Bone Hell was not much worse than when they were alive, and because they were wrapped in Undying Flame and did not fear death, their attacks would be even sharper and more powerful than when they were alive.

At the same time, in this process, Lin Moyu found the Wonder Spirits most suitable for himself.

God King Rank 6 Wonder Spirits were the limit of what he could currently withstand.

Without using Damage Transfer, if he were to suffer the retaliation of a God King Rank 7 Wonder Spirit, his physical body would quickly collapse.

If he used Damage Transfer, there would be no effect for body tempering.

In the end, Lin Moyu decided to find God King Rank 6 Wonder Spirits as much as possible, or kill five God King Rank 5 Wonder Spirits simultaneously.

The effect of both was the same.

During the tests, Lin Moyu also discovered the limit of Bone Hell.

If he relied purely on the attack power of Bone Hell itself, the limit was only killing God King Rank 4 Wonder Spirits.

For other cultivators who were only God King Rank 1, a single technique that could achieve cross-rank combat, and by three ranks at that, would definitely be considered a powerful, invincible technique.

But for Lin Moyu, a technique that could only kill enemies three ranks higher was merely mediocre.

He had too many techniques that could complete this level of combat.

But the true power of Bone Hell was not in its attack power, but in its slaves.

Any living being that died in Bone Hell would become a slave of Bone Hell.

Thus, Lin Moyu brought back high-ranked Wonder Spirits, killed them with the Skeleton Divine General, and turned them into slaves of Bone Hell.

After some testing, there was already a God King Rank 8 Wonder Spirit slave in Bone Hell.

Using this slave, Lin Moyu could easily kill any Wonder Spirit below God King Rank 8.

And the retaliation from these Wonder Spirits would all count towards him.

Chapter 1417: God King Rank 2, Mythical Lin Moyu

In Lin Moyu's view, Bone Hell was simply a mobile military camp.

The slaves inside were the soldiers, and he was the general.

When not in use, it could be retracted; when needed, it could be released at any time.

He tried it out; if unleashed with full force, the maximum range of Bone Hell could reach a diameter of 100,000 kilometers.

Once unfolded, it was like a continent floating in the void, capable of turning a patch of starry sky into a gray-white hell full of bones.

Bone Hell could not only be used to fight enemies, but also to protect himself.

He could cover himself with Bone Hell in a special form at any time and place.

Not only did it provide him with strong defense, but at the same time, any enemy that attacked him would be marked by Bone Hell.

Once marked, they could not escape the soul lock.

"It really is a powerful technique, even more powerful than I initially thought."

"Infinite Fusion has achieved merit again. I wonder if An Ran will fuse other techniques."

Infinite Fusion was currently in a weakened state and would not be used for the time being.

Lin Moyu began to take action, spreading out over ten million Skeleton Divine Generals to find Wonder Spirit after Wonder Spirit.

The Skeleton Divine Generals selected suitable Wonder Spirits and brought them back, and Lin Moyu used Bone Hell to kill them.

If there were unsuitable Wonder Spirits, Lin Moyu would recall the Skeleton Divine Generals.

The Skeleton Divine Generals vanished, and the Wonder Spirits, losing their targets, would wander aimlessly in the void.

Lin Moyu continuously enjoyed the crushing massage from the Wonder Spirits; under repeated stimulation, his physical strength was rising rapidly.

The number of slaves in Bone Hell was rapidly increasing; in less than a hundred days, the number of slaves had already exceeded ten thousand.

Two-thirds of them were God King Rank 5 Wonder Spirits, and one-third were God King Rank 6 Wonder Spirits.

During this process, Lin Moyu was simultaneously experimenting with other techniques.

The Buddha Kingdom in the Palm of the Buddha Kingdom Lich could indeed coordinate with Bone Hell, but it was a pity that the Wonder Spirits did not use any laws at all, so he could not weaken them.

Lin Moyu controlled the Buddha Kingdom Lich, randomly weakening one law while boosting the Undead Law.

The combat strength of the Undead Legion immediately rose to a new level.

The God King Rank 8 Skeleton Divine General's combat strength approached that of a God King Rank 9.

Although it did not achieve cross-rank battle, it could already be invincible within the same rank.

The whole process was smooth. In the hundred days, Lin Moyu had already fully mastered all the changes after his promotion to God King.

Time passed day by day, and his God King Rank 1 physical body was moving towards God King Rank 2.

One day, the effect of the God King Rank 6 Wonder Spirits significantly weakened.

At this time, Lin Moyu's physical body was still at God King Rank 1, but it was already much stronger than when he had just entered God King Rank 1.

From this day on, Lin Moyu began to hunt God King Rank 7 Wonder Spirits.

The number of Wonder Spirits was not small, but the higher the level of the Wonder Spirits, the more their quantity would decrease significantly.

Especially God King Rank 9 Wonder Spirits; he had only seen them a dozen times in over a hundred days.

Lin Moyu recorded all their locations.

One by one, the God King Rank 7 Wonder Spirits were killed and turned into slaves in Bone Hell, and Lin Moyu's physical body began to improve rapidly again.

Finally, after two hundred days of his entry, his physical body burst out with dazzling golden light.
