I was reborn as a young master in an invincible family of immortals

The powerful spiritual power fluctuations surging from the ground became stronger and stronger. The sand in the ancient battlefield seemed to be given life, rolling and surging wildly, forming huge sand waves that swept towards Lin Yun and others.

Amidst the sandy waves, eerie, ethereal spirits emerged. Their forms varied. Some resembled humanoid forms, distorted and deformed, their features revealing an endless venomous hatred. Others resembled beasts, shrouded in black mist and emitting eerie roars. The spiritual energy emanating from these evil spirits was so chaotic and sinister that the mere proximity sent a chill down one's spine.

"Everyone be careful, it's an evil spirit! The resentment in this ancient battlefield is too heavy, which has spawned these evil creatures. They are not easy to deal with!" Lin Yun warned loudly, holding the sword tightly in his hand, and took the lead in swinging several sharp spiritual sword auras at the evil spirits rushing towards him, trying to stop them from approaching.

However, the sword energy passed through the bodies of those evil spirits, but only caused their shapes to shake slightly, and did not cause any substantial damage. These evil spirits continued to pounce towards the crowd with their fangs and claws bared, at an extremely fast speed, and were close to them in the blink of an eye.

Facing the attack of the evil spirits, everyone hurriedly used various means to resist. Zhao Gang once again raised his shield to block the others, but the evil spirits penetrated the shield and pounced on the crowd, frightening everyone to quickly dodge to the side.

Su Yao played the Lingxi Jade Flute, and the spiritual power fluctuations turned into spiritual blades containing the power of purification, shooting towards the evil spirit. When the spiritual blades touched the evil spirit, the black smoke on the evil spirit dissipated a little, and the figure became a little illusory, but soon they re-condensed and continued to attack, as if tirelessly.

Chen Yu used the art of stealth to shuttle between the evil spirits, looking for their flaws. From time to time, he would unleash a powerful hidden spiritual blade to stab at the vital parts of the evil spirits, but the effect was minimal. These evil spirits did not seem to have any real vital parts, and even if they were hit, they could quickly recover as before.

Wang Lin continuously threw various talismans. Some of them transformed into blazing flames, attempting to burn away the evil spirits; others formed spiritual barriers, temporarily blocking the evil spirits' attacks and buying his teammates some breathing space. However, the evil spirits always easily broke through these barriers and continued to surge towards the group. For a time, everyone was caught in a difficult battle and the situation became extremely critical.

In the fierce battle, Lin Yun dodged the attacks of the evil spirits while racking his brains for a countermeasure. He suddenly remembered reading about evil spirits in an ancient book. They were composed of powerful resentment and spiritual energy. Ordinary physical attacks and conventional spiritual attacks had little effect on them. Only powerful righteous spiritual energy or purifying power with special properties could truly damage them and dispel their presence.

Lin Yun hurriedly shouted, "Everyone, try converting your spiritual energy into purification properties and attack them with the power of righteousness. Conventional methods don't seem to work on these evil spirits!"

Upon hearing this, everyone tried to adjust their spiritual energy flow, striving to transform it into a purifying force. Su Yao, relying on her profound understanding of the fusion of spiritual energy and natural forces, was the first to successfully transform the spiritual energy fluctuations released by playing the Lingxi Jade Flute into a pure purifying force. This force transformed into gentle yet powerful light waves that swept towards the evil spirit.

This time, when the light waves touched the evil spirits, they let out shrill screams, the black smoke on their bodies began to dissipate in large quantities, and their figures became more and more illusory, as if they had suffered great harm.

Seeing that Su Yao's method was effective, others followed suit, concentrating on transforming their spiritual power into purifying power, and then attacking the evil spirits.

Lin Yun used his sword skills, integrating the power of purification into every sword energy. The originally ordinary spiritual sword energy now became crystal clear, emitting a holy light. Every time the sword slashed at the evil spirit, it could cause large parts of the evil spirit's body to dissipate, and their offensive power was weakened a lot.

Chen Yu also added purification properties to the hidden spiritual blade. When he attacked the evil spirits, the effect was significant. The evil spirits that were hit would often directly dissipate part of their bodies and their movements became slow.

Wang Lin incorporated the power of purification into the flames, ropes and other attack methods transformed by the talismans, greatly increasing the power of these talismans. Not only could they effectively block the approach of evil spirits, but they could also cause continuous damage to them and accelerate their dissipation.

Although Zhao Gang could not initiate attacks like others, he held his ground firmly and used his shield magic weapon to resist the evil spirits that tried to break through the defense line, ensuring that his teammates could use their purification power to attack with peace of mind.

With everyone's concerted purification efforts, the number of evil spirits gradually decreased, and the originally surging offensive was gradually curbed. The fluctuations of spiritual power in the ancient battlefield began to stabilize, and the sand waves in the sky slowly subsided, and the surroundings returned to a certain calm.

After repelling the evil spirit, everyone was exhausted, but they had no time to rest because the source of the mysterious spiritual power fluctuations had not yet been found, and everyone knew that there must be more treasures and secrets waiting for them to discover in this ancient battlefield.

After some observation, Lin Yun discovered that where the evil spirit had just appeared, the sand had sunk to form a huge pit. From deep within the pit, a more intense spiritual power fluctuation could be faintly heard, as if that was the source of the fluctuation.

"There should be something down there. Let's go down and take a look. But everyone still needs to be careful. There might be other dangers." Lin Yun said, leading the way towards the pit.

Slowly descending the pit, the group discovered a vast underground ruin. Within the ruins lay the remains of numerous ancient buildings, their walls engraved with mysterious runes that emitted a faint glow, illuminating the dim subterranean space. In the center of the ruins stood a massive stone platform, upon which rested a crystal ball emitting a faint blue light. The crystal ball was the source of the spiritual energy fluctuations. The spiritual energy surrounding it seemed to form a vortex, swirling constantly, exuding a mysterious and powerful aura.

Everyone approached the stone platform cautiously, curiously examining the pale blue crystal ball. Lin Yun attempted to sense it with his spiritual power. The moment he touched it, a chaotic flood of images flooded his mind: fierce battles, painful roars, and powerful spiritual energies clashing. It was as if the crystal ball had witnessed the tragic battle between immortal cultivators and recorded some unknown secrets.

"This crystal ball is not simple. It seems to contain some important secrets. Maybe it is related to the formation of this ancient battlefield and the appearance of those evil spirits." Lin Yun said with a frown.

Su Yao also reached out and gently touched the crystal ball. She closed her eyes, trying to get more information from it. After a while, she opened her eyes and said solemnly: "I feel that there is an extremely powerful force in this crystal ball. It seems to be sealed, but the seal has loosened a little. The appearance of those evil spirits just now may be because there is a crack in its seal, causing the resentment and spiritual power inside to leak out."

After hearing this, everyone became more alert. They knew that they had to be cautious when facing such a mysterious object containing unknown and powerful power, otherwise if it triggered a greater crisis, the consequences would be unimaginable.

Now that they knew the evil spirits' appearance was related to the loose seal of the crystal ball, Lin Yun suggested, "We need to find a way to strengthen the seal of the crystal ball. Otherwise, it will continue to leak power and breed more evil spirits. That would be troublesome."

Everyone nodded in agreement. Wang Lin stepped forward and said, "I've researched some sealing techniques before and have prepared the corresponding talismans. However, the seal on this crystal ball is too ancient and complex. I can only try to stabilize its current state. If I want to fully strengthen the seal, I need to find more clues about it."

After that, Wang Lin took out several specially crafted spiritual energy sealing talismans, injected spiritual energy into them, and then carefully placed the talismans on key points around the crystal ball. The other team members also injected their spiritual energy into the talismans to help Wang Lin strengthen the sealing power.

With the infusion of everyone's spiritual power, the spiritual power fluctuations around the crystal ball gradually stabilized, the originally flickering blue light became much softer, and the light of those runes no longer flickered. It seemed that the seal was temporarily stabilized, preventing the situation from further deteriorating.

After securing the seal of the crystal ball, the group began to explore the underground ruins. They discovered numerous other items scattered throughout the ruins. There were broken fragments of magical weapons, which, though seemingly incomplete, could be restored to function by the sect's magical weapon pavilion experts if brought back. There were also jade stones inscribed with runes. These runes seemed to contain information about certain techniques or restrictions, potentially providing valuable assistance in the sect's research on techniques and the breaking of restrictions.

Chen Yu found a storage ring in a corner that was mostly covered in dust. He quickly picked it up, wiped off the dust with his spiritual power, and tried to use his spiritual power to sense the space inside the ring.

"Senior Brother Lin Yun, I found a storage ring, and there seems to be something inside!" Chen Yu shouted excitedly.

Upon hearing this, everyone gathered around. Lin Yun took the storage ring, injected spiritual energy into it, and examined the items inside. He saw several bottles of medicinal pills, some rare spiritual plants, and a rather ancient-looking scroll. The text on the scroll emitted a faint spiritual glow, making it clear at a glance that it must be something extraordinary.

Lin Yun gently opened the scroll and found that the content recorded on it seemed to be about the past history of this ancient battlefield and the origin of the mysterious crystal ball.

According to the book, this crystal ball was a container created by an unparalleled powerful person in order to seal the resentment and evil forces generated by a great war. It contains the souls of many cultivators and their powerful spiritual power. Once the seal is completely broken, not only will this area be plunged into endless evil spirits, it may also trigger an even more terrible disaster, and the scope of the impact may even extend beyond this desert.

In order to completely strengthen the seal of the crystal ball or eliminate the hidden dangers in it, it is necessary to find five mysterious spirit beads scattered throughout the ancient battlefield. These spirit beads served as the key points of the seal. Only by gathering them can you truly control the power of the crystal ball and resolve this potential crisis.

"It seems that our next task is to find these five mysterious spirit beads. This is not only related to our own safety, but also to the peace of the surrounding areas." Lin Yun looked at the records in the book and said to everyone with a serious expression.

Everyone understood the seriousness of the situation and immediately decided to split up and search for the five mysterious spirit beads. Lin Yun and Su Yao would form one group, Chen Yu and Wang Lin would form another, and Zhao Gang would act alone. After all, the underground ruins were vast, and while splitting up the search would improve efficiency, it would also mean facing greater danger for each individual.

"Everyone be careful. If you make any discovery or encounter any danger, use the sound transmission talisman to notify others immediately. We must gather the spirit beads as soon as possible to resolve this hidden danger." Lin Yun warned. Everyone nodded and set off in different directions, stepping into this underground ruins full of mystery and danger, and began a tense search journey. The unknown crisis hidden in the dark seemed to be quietly watching their every move.
