Mortals cultivate immortality, I have a Chaos Tower

Lin Fan, Jin Buke, Zhong Ling'er and Jiang Shuiling were all curious about the origin and function of this leather armor, so they decided to conduct more in-depth research and testing.

"This leather armor is extraordinary, it must be hiding some secrets." Lin Fan said solemnly, "We must find out its true purpose, maybe it can help us increase our strength."

After a short rest, the four of them found a relatively safe place and decided to test the mysterious leather armor again. In order to verify its sturdiness, Lin Fan took out the Qiankun Axe, which he got from ancient ruins. It was extremely sharp and could be called a weapon that could cut through mountains. Lin Fan took a deep breath, held the Qiankun Axe tightly with both hands, gathered his true energy throughout his body, and suddenly chopped the leather armor with an axe.

"Bang!" The huge axe blade fell on the leather armor, making a sound like metal clashing, shaking the air around it. However, when the smoke and dust cleared, the leather armor was still intact, without even a scratch left.

"This... is incredible!" Jin Buke's eyes widened, looking at the intact leather armor in disbelief. He knew the power of the Qiankun Axe, if it was an ordinary object, it would have been split in half long ago, but the leather armor in front of him didn't even leave a trace.

Zhong Ling'er also frowned, feeling that this leather armor was unusual. "Let's try it with fire."

Jiang Shuiling nodded in agreement, then pinched the magic formula and cast a blazing flame. This flame was not an ordinary fire, but the true flame of earth fire that she had cultivated for many years, which was enough to burn gold and stone. The flame quickly wrapped around the leather armor and burned fiercely. The temperature around it rose instantly, and the air was filled with a scorching breath.

"Hiss——" The flame continued to burn for a moment, however, when the flame gradually went out, the leather armor remained as good as before, without even the slightest burn mark left.

"Even the flames can't hurt it at all!" Jiang Shuiling was shocked and hurried forward to check. She found that the surface of the leather armor was still as smooth as new, as if the flames had never existed.

Next, they tried other methods, using various magical tools, talismans and even poisons to test the leather armor. The results were without exception: the leather armor remained intact, as if it was not affected by any external factors at all.

"It seems that this leather armor is definitely some kind of extremely powerful magic weapon." Lin Fan pondered for a moment and said, "It may be a body protection artifact with extremely strong defensive power. However, we still cannot fully understand its function."

"But where did it come from? We have seen many magical weapons, but never such an indestructible object." Zhong Ling'er's tone was full of doubt.

Jin Buk frowned, a trace of thought flashed in his eyes, "Perhaps this leather armor is a relic of some ancient powerful being, or it may be some special protective device."

"Yes." Jiang Shuiling said softly, "Such a powerful defense. If we can unlock its secret, it may be of great help to our future battles."

The four people stood in front of the leather armor, their faces full of solemnity and confusion. Although they had confirmed the extraordinary nature of the leather armor, its origin and true purpose were still a mystery. They understood that this magic weapon was by no means an ordinary thing, and it was likely related to an extremely powerful existence.

Lin Fan took a deep breath and stared at the leather armor lying quietly on the ground. A trace of determination flashed in his eyes. "Since we can't unlock its secret for the time being, let's keep it with us. Maybe one day in the future, we can find out its true origin and how to use it."

Lin Fan carried his sword on his back and looked ahead with a serious look. His journey was not over yet. In fact, this was just a small checkpoint on the road to the Holy Ruins. The real danger was brewing deep in the swamp he was about to step into.

It is said that this swamp was the burial place of a great man in ancient times. His magical powers shocked the world. However, after his death, his resentment and power remained here, making this swamp strange and abnormal. No one knows who this great man is, and no one dares to explore the secrets in depth. Every monk who entered the swamp never came back alive. It is like an invisible giant mouth, quietly swallowing those adventurers who are eager for power and opportunity.

As Lin Fan stepped into the forbidden area, the surrounding scene became more and more unfamiliar. He found that the ground under his feet was no longer solid, but slippery and soft. Every step he took made a sticky sound. With a "gulp", it seemed that something was surging under the muddy water, as if something would break out of the ground at any time and drag him into the abyss.

The air was filled with a disgusting smell of decay, like a pile of corpses that had not decayed for many years. Lin Fan looked up at the sky and saw dark clouds hanging low, as if they would fall at any time. The dull and depressing atmosphere made people shudder. Although the sun was hard to see here, Lin Fan could still feel the burning gazes, as if countless pairs of eyes were spying on his every move in the dark.

"This place is really not simple..." he whispered to himself.

This was not the first time that Lin Fan had felt danger, but this time the feeling was different from any previous time. Every inch of land and every breath of air in the swamp seemed to be filled with an indescribable malice. This malice was invisible and intangible, but it followed him like a shadow, making him nervous all the time.

Lin Fan walked in the swamp for several hours, and the surrounding scenery had hardly changed, as if every piece of mud and every dead tree was the same. Suddenly, he heard a low mumbling voice in his ears. The voice was intermittent, and seemed far and near, as if an ancient soul in the depths of the swamp was calling him. The voice carried a bewitching power, as if it wanted to lead his mind into an irresistible abyss.

Lin Fan paused, and quickly mobilized his spiritual power, spreading his consciousness like a tide to resist this sudden attack. However, the voice seemed to be omnipresent, bypassing his spiritual power protection and directly drilling into his mind, provoking his inner defenses.

"Come out! I know you are trying to control my consciousness." Lin Fan snorted coldly, with a cold light flashing in his eyes.

However, the only response he got was the intermittent whispers, as if the swamp itself was mocking his powerlessness. Lin Fan realized that this swamp was not only a physical danger, but also a mental torture field. It would try to disintegrate the will of those who entered, leading them to madness or death.

"Although this method is strange, it can't shake me." Lin Fan took a deep breath, adjusted his mind, and continued to move forward.

As Lin Fan's footsteps went deeper, the stench in the air became stronger, and the mud under his feet became more and more difficult to walk. Suddenly, Lin Fan felt a strange vibration coming from the ground. He quickly stopped and looked down at the ground. He saw that the mud under his feet began to wriggle restlessly, as if some creature was lurking in the muddy water.

"It seems that the real enemy is coming." Lin Fan clenched his sword and looked around vigilantly.

The next moment, the ground suddenly cracked, and a huge mud vortex suddenly emerged, like a huge mud mouth that opened, trying to swallow Lin Fan. Lin Fan's eyes focused, and his body instantly jumped up, avoiding the direct attack of the vortex. However, the vortex did not stop, but instead quickly chased him as if it had life.

Lin Fan frowned and moved his body quickly, but he found that every time he stood still, the soil under his feet would immediately collapse, and a whirlpool would follow closely behind him, leaving him almost no chance to breathe.

"We can't delay any longer." Lin Fan's mind moved, and the long sword was instantly unsheathed, with the sword energy surging, directly slashing at the mud vortex. The sword energy was like a rainbow, instantly slashing into the mud, causing a splash of mud and water. However, after the vortex was hit by the sword energy, it did not break like normal objects, but healed quickly, as if it was not affected by any physical attack at all.

"It is indeed a strange power." Lin Fan thought to himself. Facing such an enemy, conventional means were obviously ineffective, and he had to find its weakness.
