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

Lin Yun stared intently at the Shadow Cult expert, shrouded in black mist, his eyes filled with solemnity and determination. At this moment, their ability to break through the encirclement depended on their ability to defeat this powerful enemy.

The Shadow Cult master wielded a long sword emitting a black glow. His figure moved like lightning, instantly closing in on Lin Yun and the others. The long sword brought up a sharp, cold wind, mixed with a hint of evil, as it fiercely slashed towards Lin Yun.

Lin Yun didn't dare to delay and hurriedly raised his sword to meet the blow. With a loud clang, the swords clashed, splashing a dazzling light. Lin Yun felt a powerful force running through his arm, causing it to numb slightly, but he gritted his teeth and withstood the blow with all his might.

At the same time, Li Feng seized the opportunity and lunged at the Shadow Cult expert from the side. Using the protection of his gauntlet, he launched a fierce punch towards the expert's waist. This punch contained Li Feng's full strength; if it landed, it would surely inflict pain.

However, the Shadow Cult master seemed to have noticed it long ago. He slightly turned his body and easily avoided Li Feng's attack. Then, he swung his long sword with his backhand, and a black blade shot towards Li Feng.

Li Feng was unable to dodge and the knife energy grazed his shoulder, leaving a blood mark. He groaned and took a few steps back.

"Li Feng, are you okay?" Lin Yun's heart tightened when he saw this and he shouted loudly.

"I'm fine, let's deal with this guy first!" Li Feng said gritting his teeth. Although he was injured, the fighting spirit in his eyes did not diminish at all.

Su Yao saw Li Feng injured and quickly cast an auxiliary spell. A soft spiritual light enveloped Li Feng, stopping his bleeding and healing his wounds, and quickly restoring his spiritual power.

Chen Yu wasn't idle either. He shook the flame gourd and chanted a spell. A blazing flame swept towards the Shadow Cult expert. Wherever the flame passed, the air was burned and twisted, and it rushed towards the expert.

The Shadow Cult expert remained calm in the face of the flames. The black mist surrounding him seemed to possess some kind of fire-resistant ability. When the flames approached, the mist automatically swirled, significantly weakening the flames' power. However, Chen Yu's attack also successfully attracted some of his attention.

Lin Wan'er was still hiding her figure. She took this opportunity to quietly go behind the Shadow Cult master, holding a special dagger in her hand, ready to find an opportunity to deliver a fatal blow.

During his brief encounter with the Shadow Cult expert, Lin Yun kept a close eye on the changes in the black mist surrounding him and the black light on his sword. He noticed that whenever the expert launched a powerful attack, the black light on his sword would momentarily weaken, and the black mist around him would briefly become turbulent.

"Everyone, pay attention. After he launches an attack next time, we will concentrate our forces to attack the places where the light of his long sword is weakened and the fog is disordered!" Lin Yun shouted loudly. He knew very well that this might be their only chance to defeat this master.

The team members nodded in understanding as they heard this. They were now working closely together, concentrating on waiting for the perfect opportunity.

Not long after, the Shadow Cult master swung his long sword again, launching an even more fierce attack. This time, he slashed towards the center of the defensive circle where Lin Yun and the others were. The black light brought by the long sword almost illuminated the entire passage.

Lin Yun and the others were on full alert. As the long sword was about to strike, they all employed their own methods to dodge. Lin Yun dodged, leaping back several steps. Li Feng, using his gauntlet to protect him, withstood the blow head-on. Although he was knocked back a few steps, he had managed to buy his teammates some time.

Su Yao continued to cast auxiliary spells to ensure that everyone could maintain sufficient spiritual power and defense in this fierce collision. Chen Yu shook the flame gourd again, spewing out an even more violent flame, burning towards the Shadow Cult master, trying to disrupt his attack rhythm.

Just after the Shadow Cult master's attack landed, as Lin Yun observed, the black light on the long sword instantly weakened, and the black mist on his body also became disordered.

"Now, attack!" Lin Yun shouted, charging towards the Shadow Cult expert. His sword shone brightly, emitting a sharp aura as he stabbed precisely at the spot where the expert's blade's light had faded.

Li Feng also endured the pain in his shoulder and rushed forward again. He waved his gauntlet and struck at the area on the master's body where the black mist was turbulent.

Chen Yu exerted the power of the flame gourd to the extreme. A scorching flame swept towards the Shadow Cult master, trying to completely envelop him in the sea of ​​fire.

Su Yao quickly formed seals with her hands, muttered something, and cast an auxiliary spell to enhance the power of the attack, bringing the power of her teammates' attack to a new level.

Lin Wan'er also appeared at this critical moment. She suddenly jumped out from behind the Shadow Cult master and stabbed the master's vital part on the back of his neck with the dagger in her hand.

Under the joint attack of everyone, the Shadow Cult master was immediately in trouble.

Lin Yun's sword accurately pierced the area where the long sword's light had weakened, and instantly a powerful spiritual energy flowed through the sword into the expert's body, causing him to tremble. Li Feng's fierce attack also hit the area where the black mist was turbulent. The expert felt a sharp pain in his waist and his body couldn't help but stagger.

Chen Yu's flames completely enveloped him, and the scorching heat quickly dissipated some of the black mist on his body, and he began to feel the burning pain. Su Yao's auxiliary spells greatly increased the power of his teammates' attacks, making each blow cause more serious damage to him.

Lin Wan'er's dagger successfully pierced the master's vital part on the back of the neck. Although it failed to kill him, it did cause him serious injuries.

The Shadow Cult master let out a painful roar. He never expected that Lin Yun and others could find his weakness so accurately and launch such a fierce attack.

At this moment, his strength was greatly affected, and his originally fierce attacks became slow.

"Don't stop, keep attacking and take the opportunity to break out!" Lin Yun shouted loudly. He knew that this was a great opportunity and he must not let it go.

Upon hearing this, the team members responded one after another. They took advantage of the moment when the Shadow Cult master was injured and launched another more fierce attack. Lin Yun swung the sword in his hand continuously, bringing up sharp sword energy and continued to slash at the master. Li Feng, on the side, used the protection of the gauntlet to engage in close combat with the master, constantly attacking his weak parts. Chen Yu shook the flame gourd and chanted a spell. Fiery flames shot out from the gourd mouth and burned towards the master, causing him to struggle painfully in the flames. Su Yao cast auxiliary spells on the side to enhance the defense of the teammates and restore their spiritual power to ensure that everyone could continue to fight in this fierce battle. Lin Wan'er was still hiding her figure. She shuttled among the enemy group, looking for the weak points of other Shadow Cult members so that she could deliver a fatal blow.

Under the continuous attack of the crowd, the Shadow Cult master finally couldn't hold on anymore. His body began to shake, and the long sword in his hand fell to the ground with a "clang".

"Hurry up!" Lin Yun shouted, seeing the opportunity had arrived. He was the first to rush towards the passage behind the Shadow Cult master. The team members followed suit, breaking through the circle of Shadow Cult members and running deeper into the passage.

The Shadow Cult members panicked when they saw the expert defeated. Although they were numerous, they had just witnessed the strength of Lin Yun and the others, so they didn't dare to pursue them rashly.

In this way, Lin Yun and others successfully broke through the siege and continued to run towards the depths of the Shadow Cult stronghold. They knew that there might be more secrets waiting for them to discover, and they must complete the exploration mission as soon as possible and then return to the Immortal Sect safely.

Lin Yun and the others ran furiously along the passage. Temporarily free of the Shadow Cult's pursuit, they dared not let their guard down. The passage remained dim, and the evil runes on the walls flickered with an eerie light, as if telling of the evil deeds that had occurred there.

After running for a while, the passage began to open up, and a large hall appeared in front. The door of the hall was closed, and it was engraved with complex runes. The runes exuded a strong evil aura, which made people feel very depressed.

"There must be something important in here. Everyone be careful and prepare to open this door." Lin Yun said. He stopped and looked at the door carefully, thinking about how to open it.

The other team members also came closer. They also felt that there might be a big secret hidden behind this door, and their eyes revealed curiosity and nervousness.

Su Yao cast the detection spell again. She quickly formed seals with her hands and muttered something, trying to sense the situation behind the door. After a while, she opened her eyes and said solemnly, "Lin Yun, I detected a very powerful evil force behind the door, and there seems to be something similar to a formation. It's not easy to deal with."

Lin Yun frowned upon hearing this. He knew that opening this door and exploring its contents would inevitably be a huge challenge, but they had already come this far and could not give up halfway.

"Let's think of a solution together. Let's try to attack this door with spiritual power first to see if we can find a breakthrough." Lin Yun suggested.

The team members nodded, each channeling their spiritual energy, and then launched an attack towards the door. The sword in Lin Yun's hand shone brightly, bringing with it a sharp sword energy, shooting towards the door. Li Feng brandished his gauntlet and punched the door with all his might. Chen Yu shook the flame gourd, chanting a spell, and a blazing flame shot out from the gourd mouth, burning towards the door. Su Yao cast auxiliary spells on the side, enhancing the spiritual power and defense of the teammates so that they could maintain sufficient combat effectiveness during the attack on the door. Lin Wan'er remained hidden, observing the surrounding situation to prevent other accidents.

Under the combined attack of everyone, the door began to tremble violently, and the runes on the door flickered, as if it would collapse at any time.

After some effort, the door finally opened slowly, and a stronger evil aura rushed towards them, making Lin Yun and others frown.

The light in the hall was dim, and one could vaguely see some objects placed in a disorderly manner, as well as some huge stone pillars. The stone pillars were engraved with evil runes, and the runes flashed with strange light, as if telling of the evil nature of this place.

In the corner of the hall, there is a platform, on which is placed a treasure box emitting a faint light. There are some small formations running around the treasure box, as if protecting it.

"That treasure box looks very important. Everyone, be careful and see what's inside." Lin Yun said. He walked towards the platform and the other team members followed. They approached the treasure box cautiously, ready to find out what was inside.

When they approached the treasure box, they could feel a powerful restrictive force emanating from the formation surrounding the treasure box, trying to prevent them from getting closer.

"This formation is a bit tricky. Let's work together to think of a way to break it." Lin Yun said. He stopped and carefully observed the operation of the formation, thinking about how to break it.

The other team members also stopped. They also felt the power of this formation, and their eyes revealed solemnity and tension.

In this way, Lin Yun and others faced new challenges deep in the Shadow Cult stronghold. Whether they could unlock the restrictions of the formation around the treasure box and obtain the important information that might be hidden inside was still unknown.
