The Skeleton Sword is a high-grade Xuan-level treasure. After adding the power of Lin Yun's martial soul, it can cut iron like clay. It must be able to deal with these giant beetles without any problems.
Lin Yun immediately held a sword in one hand and rushed towards one of the giant beetles.
With a wave of the skull sword in his hand, it turned into a sharp sword light and landed on the giant beetle's metallic carapace.
Tsk!
Accompanied by the sound of a hard object tearing apart, the giant beetle's indestructible carapace was torn apart like a piece of paper by the skull sword in an instant.
As the blade moved through the flesh, the crack extended from the corner of the mouth to the chest and abdomen, and then to the tail, traversing the entire body of the giant beetle.
The giant beetle fell to the ground, and then the body was transformed into mysterious energy and merged into Lin Yun's body.
After absorbing this mysterious energy, although Lin Yun's body surface remained unchanged, his skin, muscles, and bones underwent earth-shaking changes at the microscopic level.
The human body is made up of countless tiny life units, and these tiny life units are made up of countless basic particles.
These basic particles are separated by a large distance from each other. This is like two mung beans separated by a street.
At this moment, all the basic particles that make up Lin Yun's body are reducing the distance between them.
Although the distance reduced is insignificant, it is only the effect of killing a giant beetle.
If hundreds or thousands of giant beetles are killed, the distance between these basic particles will shrink to a terrifying level.
The smaller the distance between elementary particles, the greater the density of the body and the greater the structural strength of the body.
When the distance between basic particles shrinks to a certain extent, the body will become extremely strong and the body's defense will become extremely abnormal.
Thinking of this, Lin Yun's fighting spirit instantly rose.
He held the skull sword in one hand, like a terrifying razor, and plunged unstoppably into the giant beetle pile, causing a bloody storm in the army of hundreds of beetles.
He was like a hurricane, and all the giant beetles fell down wherever he passed.
Every time a giant beetle falls, a mysterious energy will flow into Lin Yun's body, transforming his body from a microscopic level, making his body stronger.
The current ability of the Demonic Sword can greatly increase the sharpness of the weapon.
With the ability of the Demon Sword, the Skeleton Sword can easily break through the defenses of these giant beetles.
Without the ability of the Demon Sword to hold them, it would be impossible to break through the carapace of these giant beetles with just the Skeleton Sword.
It is precisely for this reason that Lin Yun must activate the Demon Sword throughout the battle.
The Demon God's Sword is a heaven-level martial spirit, and the consumption required to maintain it is too huge. Every second it is turned on, a large amount of vitality is consumed.
It is precisely because of this that Lin Yun must race against time to kill as many giant beetles as possible in the shortest possible time.
In just a few minutes, Lin Yun consumed all the energy in his body.
But fortunately, Lin Yun still has the trump card of accumulating Yuan inscription pattern.
He immediately activated the Yuan-Storing Inscription and drew out the reserve energy from the Yuan-Storing Inscription to continue fighting.
Every few minutes, Lin Yun would re-extract vitality from the energy-accumulating inscriptions to maintain the consumption required for his martial spirit.
…
Half an hour later, all the giant beetles were eliminated by Lin Yun and turned into energy to transform Lin Yun's body.
After being transformed by these energies, Lin Yun's skin became shiny and full of heavy metal texture. This was exactly the effect of the increased density of elementary particles.
At this time, Lin Yun's physical strength had reached a very abnormal level.
Even though he has not yet cultivated the adamantine body of the "Immortal Divine Body" to a small degree, his body's defense has already surpassed that level.
It is difficult for a warrior in the warrior realm to hurt Lin Yun with ordinary weapons.
While Lin Yun was secretly feeling the changes in his body, the Phantom Emperor's voice suddenly sounded out of thin air, and then two light gates appeared in front of Lin Yun.
Lin Yun had no intention of backing down, and without hesitation chose to enter the red light door, entering the fifth floor in one go.
The scene changed, and Lin Yun came to a world that could not be described in words, like a purgatory on earth.
"Fifth level, endurance test!"
Looking around, this is a red land paved with countless lava rocks.
Between the pieces of lava rocks, rolling magma flows, isolating the lava rocks and forming small isolated islands.
Standing on these "isolated islands", even the air becomes extremely hot, and even the shoes seem to be melted.
Underfoot is the extremely hot lava purgatory, while above the head is the extremely cold ice and snow storm, like a huge monster, covering the entire sky, as if it is going to devour the earth under its feet.
In the ice and snow storm, violent lightning flashed all the time, bombarding the ground one after another.
Hot and cold air currents alternate between lava purgatory and ice and snow storms, forming violent and raging high-pressure hurricanes with wind speeds so fast that they can tear the human body apart.
Being in this high-pressure storm is like being in a dense liquid, making it difficult to even move.
Lava purgatory, ice and snow storms, lightning and thunder, raging hurricanes, the environment is extremely harsh and harsh, just like going back to the beginning of the world.
If they were ordinary people, any extreme conditions here could kill them in an instant.
But at this time, Lin Yun was suffering from four extreme conditions at the same time!
He sat cross-legged on the lava stone, and the hot steam continued to rise, scorching his body, burning his skin until it turned red, and his whole body was constantly smoking.
But he sat there as if nothing had happened, as if he didn't feel the heat at all.
The violent and raging hurricane was like invisible sharp blades, cutting his body one after another, cutting all his clothes into pieces, but it could not leave a single scar on his body.
Brilliant lightning fell from the sky and struck his body with a roar, blasting the lava rocks beneath him into pieces.
However, he still sat on the cracked lava stone without any reaction, and his whole body was still unscathed, not even a scratch on his skin.
In this way, the three natural energies continued to destroy Lin Yun's physical body, and at the same time, they continued to temper Lin Yun's physical body, just like tempering steel.
Fortunately, the energy at this level has been converted into natural energy, which is used to maintain this extreme natural environment and has not converged into an enemy.
Since Lin Yun entered this level, he has never seen an ownerless soul.
Lin Yun quickly understood that the enemy on this level was actually the natural environment itself.
The natural environment is both his enemy and his reward.
As long as he adapts to the natural environment here, he will be able to develop resistance to the three natural attributes of wind, fire, and thunder.
In this way, he will not have to fear the attacks of these three natural energies in future battles.
