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

Lin Yun and the others gathered around the glowing treasure box, their eyes fixed on the small formation surrounding it, trying to find a way to break it. The formation seemed small, but it exuded a powerful restraining force. Every flicker of rune light seemed to warn everyone not to approach easily.

Lin Yun squatted down and carefully observed the operation of the formation. He found that these runes were not arranged in a disorderly manner, but flowed according to a specific cycle. And each time they flowed to a specific position, the power of the formation seemed to weaken slightly.

"Look everyone, the runes of this formation flow in a certain pattern. We will wait and see when its power weakens, launch an attack together, and see if we can break it." Lin Yun said softly to his teammates, his eyes revealing concentration and determination.

Upon hearing this, the team members nodded and adjusted their states, preparing to cooperate with Lin Yun's actions. Su Yao quickly formed seals with her hands, muttered something, and cast auxiliary spells to enhance the spiritual power of her teammates, ensuring that everyone had enough strength to deal with possible counterattacks in the next action. Li Feng clenched his fists wrapped in gauntlets, ready to deliver a powerful blow at the critical moment. Chen Yu shook the flame gourd and silently chanted an incantation, ready to unleash the power of the flame spell to the extreme. Lin Wan'er still concealed her figure. With her keen perception, she secretly paid attention to the movements around her to prevent other unexpected situations.

Soon, Lin Yun noticed that the runes of the formation had flowed to the expected weak point. He stood up suddenly and shouted, "Now, attack!"

With that, the sword in his hand shone brightly, emitting a sharp sword energy that shot towards the formation. Simultaneously, Li Feng threw a powerful punch, the wind from his fist enveloping the spiritual energy and fiercely smashing into the formation. At the same moment, Chen Yu shook the flame gourd, and a blazing flame shot out from the gourd mouth, sweeping towards the formation. Su Yao continued to cast supporting spells, enveloping everyone in a gentle spiritual light, enhancing their offensive power and defensive capabilities.

Under the combined force of their attacks, the formation trembled violently, its runes flickering, as if struggling. However, the formation's resilience far exceeded everyone's imagination. Despite such a fierce attack, it did not collapse immediately.

"Don't stop, keep attacking!" Lin Yun shouted. He gritted his teeth, concentrated his spiritual power again, and waved the sword in his hand continuously. Sword Qi shot towards the formation one after another.

The other team members responded, increasing their attack power. Li Feng's fists rained down like raindrops, each one carrying immense force. Chen Yu's flames surged, engulfing the entire formation in flames. Su Yao also continuously cast auxiliary spells, providing continuous support for her teammates.

Finally, under the unremitting attacks of the crowd, the formation made a crisp cracking sound, and then the light went out, completely losing its restrictive effect.

"Great, the formation is broken!" Lin Yun breathed a sigh of relief, a relieved smile on his face. But he knew that this was not the time to relax, because the treasure box emitting a faint light might hide even more shocking secrets.

Lin Yun slowly walked towards the treasure box that had lost the protection of the formation, and the other team members followed closely behind him. Everyone's eyes were fixed on the treasure box, their hearts full of anticipation and a hint of nervousness.

When Lin Yun reached out and touched the treasure box, a cold breath spread along his fingertips, but he did not retreat. Instead, he gently opened the lid of the treasure box.

As the lid opened, a dazzling light shot up from the treasure box. The light seemed to contain countless images and information, dazzling the eyes. Lin Yun and the others subconsciously closed their eyes, and only slowly opened them after the light faded slightly.

There are several items placed in the treasure box. The first thing that catches the eye is an ancient scroll. The paper of the scroll looks very old, but it is well preserved. It is densely covered with obscure words and mysterious runes, exuding an ancient and mysterious atmosphere.

In addition, there is a crystal ball emitting a faint blue light. There seems to be clouds and mist inside the crystal ball, and some blurry images can be vaguely seen flowing in it, as if it is hiding some important information.

Finally, there is a black stone. The surface of the stone is as smooth as a mirror, but it exudes a strong evil aura, which seems out of tune with the surrounding objects.

"These things don't look simple, especially this ancient book and crystal ball. Maybe they contain important secrets of the Shadow Cult." Lin Yun said. He carefully picked up the ancient scroll, opened it, and found that the text inside was even more profound and difficult to understand. It was impossible to decipher it in a short time.

Su Yao picked up the crystal ball and gently turned it, trying to see something from the blurry image. "Lin Yun, the image in this crystal ball seems to be a scene from some place, but it's not very clear. I need to study it carefully." Su Yao said with a frown.

Li Feng stared at the black stone, feeling a faint sense of unease. "This stone exudes a strong evil aura. It doesn't seem like it's a good thing. We need to be careful," Li Feng warned.

Just as everyone was carefully studying the items in the treasure box, suddenly, a low buzzing sound was heard throughout the stronghold. The sound seemed to come from all directions, making people feel creepy.

"Oh no, we have triggered some mechanism or alarm, everyone be careful!" Lin Yun's face changed and he shouted loudly.

As soon as he finished speaking, a large number of Shadow Cult members poured out from all corners of the hall. Their number was even greater than what they had encountered before, and the evil aura on each of them was even stronger, with fierceness and determination revealed in their eyes.

"Hmph, you little bastards from the Immortal Sect, how dare you touch our treasures? Today is the day you die!" said a member of the Shadow Cult viciously.

Lin Yun and others quickly formed a defensive circle with their backs to each other, gripping their weapons tightly, ready to face the upcoming life-and-death struggle.

"Don't panic, everyone. If we can break through once, we can break through a second time!" Lin Yun tried to boost morale, although he knew in his heart that the situation this time was more severe than before.

The Shadow Cult members didn't give them much time to think, and rushed towards Lin Yun and the others, brandishing their weapons. For a moment, the hall was filled with the flashing of swords and the shouting of killing.

Lin Yun, swift as lightning, charged into the enemy horde. His sword swung, unleashing wisps of sharp energy as he slashed at the enemy with pinpoint precision. Each strike wounded or even felled a member of the Shadow Cult. Li Feng, using his gauntlet for protection, engaged in close combat within the enemy horde. His agility was unwavering, and every punch and kick dealt a devastating blow. Su Yao, on the side, cast supporting spells, boosting the defenses and restoring spiritual power for her teammates, ensuring they remained effective throughout the fierce battle. Chen Yu swung his flame gourd, chanting an incantation. Streams of blazing flame shot forth from the gourd's mouth, consuming the Shadow Cult members. Enemies roared in pain and dodged in their wake. Lin Wan'er, still concealed, weaved through the enemy horde, searching for their weak points to strike a fatal blow.

However, this time, the Shadow Cult members were not only numerous, but they also seemed to have mastered some new attack techniques and coordination methods. They were divided into several small teams, coordinating with each other tacitly. Some were responsible for attacking Lin Yun and his team's defense circle head-on, while others launched sneak attacks from the side and rear, making Lin Yun and his team defenseless.

In this fierce battle, Lin Yun and others gradually felt a little tired, and the defense line began to loosen.

Although the situation was extremely unfavorable to Lin Yun and others, they did not give up. They still gritted their teeth and struggled desperately in this desperate situation.

During the battle, Lin Yun kept observing the enemy's attack methods and weaknesses. He found that some members of the Shadow Cult would briefly reveal a red mark on their chest when launching an attack. This mark seemed to be a source of their power or a key part related to some evil spell.

"Everyone, look carefully. Those Shadow Cult members have a red mark on their chests. It might be their weakness. Concentrate your attacks there!" Lin Yun shouted loudly. He hoped that by finding the enemy's weakness, he could bring them a glimmer of hope.

Upon hearing this, the team members focused their attention on the red marks on the chests of the Shadow Cult members. Seizing an opportunity, Li Feng charged forward, fiercely smashing his gauntlet against the red mark on the chest of a Shadow Cult member. Chen Yu also adjusted the angle of his flame gourd, precisely spraying the flame onto the red mark on the chest of another Shadow Cult member.

Su Yao increased the power of her auxiliary spells to provide stronger support for her teammates. Lin Wan'er also appeared from behind the enemy at the right time, holding a special dagger in her hand, and stabbed the red mark on the chest of the Shadow Cult member fiercely.

After everyone worked together, the red marks on the chests of several Shadow Cult members were finally broken by the concentrated attacks of everyone. Those members let out a shrill scream, then fell to the ground with a bang, and turned into a cloud of black smoke and dissipated in the air.

Seeing that there was a turning point, everyone was cheered up and continued to attack other members of the Shadow Cult using the same method.

With everyone's joint efforts, the attack rhythm of the Shadow Cult members was disrupted, they began to show signs of panic, and their defense line gradually loosened.

Lin Yun and the others seized this opportunity, gritted their teeth, and launched another, even more fierce attack. They broke through the encirclement of the Shadow Cult members and rushed towards an exit of the hall.

Although they suffered a lot of injuries in this life-and-death struggle, they relied on their tenacious will and trust in each other to successfully find a glimmer of hope in the desperate situation and continued to move towards the goal of completing the exploration mission.

After Lin Yun and the others struggled to break through the encirclement of the Shadow Cult members, they ran towards an exit of the hall. Their figures quickly shuttled through the dim hall, followed by chaotic shouts and chasing Shadow Cult members.

"Everyone, hurry up and keep up, don't fall behind!" Lin Yun shouted loudly while running. He looked back from time to time to check on his teammates to make sure everyone could keep up with the team.

The team members also gritted their teeth, endured the pain in their bodies, and desperately chased Lin Yun's footsteps. While running, Su Yao did not forget to cast auxiliary spells to restore the spiritual power and relieve the pain for her teammates.

Finally, they successfully ran out of the hall and came to a new passage. The light in the passage was still dim, but slightly brighter than the hall.

"Let's find a place to hide first and recover our physical and spiritual strength, then we'll continue exploring." Lin Yun said. He looked around and found several small rooms on one side of the passage, so he led his team members to run towards one of the rooms.

After entering the room, Lin Yun quickly closed the door and cast a simple spell to conceal the breath, hiding the breath in the room to prevent the Shadow Cult members from finding them easily.

The team members collapsed on the ground, gasping for breath. Their injuries and consumed spiritual energy would take time to recover.

Su Yao took out some healing pills from the storage ring and distributed them to her teammates. "Everyone, eat these pills quickly and recover from your injuries." Su Yao said. She also swallowed a pill and began to circulate her spiritual power to speed up the recovery of her injuries.

Lin Yun sat aside, pondering the items he had just seen in the treasure box and the direction of his next exploration. He knew that although they had temporarily escaped the pursuit of the Shadow Cult members, there were definitely more secrets waiting for them to discover within the Shadow Cult stronghold. They also had to complete their exploration mission as quickly as possible and return safely to the Immortal Sect.

During this short rest period, Lin Yun and others in this dangerous Shadow Cult stronghold recovered their physical and spiritual strength while thinking about their next move. They knew that there were more challenges waiting for them ahead.
