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

Lin Yun looked at the dreamlike valley scene before him, his heart filled with curiosity, yet he couldn't help but feel a strong sense of vigilance.

The journey had been filled with countless hardships and dangers. Behind every seemingly beautiful place lay a deadly danger. While the beautiful valley, the ancient castle, and the gorgeous gardens before him exuded a captivating charm, Lin Yun knew that in this mysterious world of cultivation, the more alluring the appearance, the more likely it was to conceal unpredictable dangers, just like the traps and monsters they had encountered before, always poised to strike the moment they let their guard down.

He wondered silently, what secrets lay hidden in this valley? Would that ancient castle hold clues to the Shadow Cult? Or perhaps some powerful guardian power awaited them? Regardless, now that he had come this far, he had to find out. Even if the path ahead was a dangerous one, he had no choice but to brave the storm.

At that moment, sunlight streamed across the valley, casting a golden glow over the ancient castle and the exotic flowers and plants in the garden, making everything appear even more dreamlike. The moss on the castle walls glowed a vibrant emerald green in the sunlight, contrasting with the gray stonework, adding to its ancient charm. In the garden, the giant, umbrella-like flowers swayed gently in the breeze, their multicolored petals shimmering with enchanting light, their fragrance filling the air with a sweet and alluring aroma. However, Lin Yun remained unfazed by the beauty; his eyes perpetually scanned his surroundings for any signs of danger.

"Su Yao, let's be careful. This valley looks beautiful, but it is definitely not that simple. Be prepared to deal with danger at any time." Lin Yun whispered to Su Yao beside him. Although his voice was soft, his tone revealed unquestionable seriousness.

Su Yao nodded slightly and responded solemnly: "Well, I understand. The experience along the way has made me dare not be careless at all."

As they spoke, the two of them walked cautiously into the valley, taking every step with extreme caution, as if the ground beneath their feet might suddenly trap them at any time.

As they approached the ancient castle, Lin Yun could increasingly sense a mysterious and ancient aura. This aura was different from what he had felt elsewhere before; it was deeper and heavier, as if carrying thousands of years of history and countless secrets.

The castle's gates were tightly shut. They were two massive wooden doors inlaid with faded metal ornamentation. Despite the wear and tear of time, their former beauty still shone through. Rows of arrow slits dotted the walls above the gates, silently recounting the battles of the past. Lin Yun looked up at the towering towers, wondering what the castle's interior held. What secret mechanisms or powerful entities might be hidden within?

"This castle looks quite old. I wonder what it looks like inside." Lin Yun said softly. As he spoke, he stretched out his hand, wanting to touch the tightly closed door and feel the spiritual power fluctuations on it.

But when his hand was about to touch the door, a weak repulsive force gently bounced his hand back.

"Huh? This gate is restricted." Lin Yun frowned, secretly surprised. He had originally thought that although this castle was mysterious, it might be easy to enter, but he didn't expect to encounter an obstacle as soon as he reached the door.

Seeing this, Su Yao also stepped forward and cast a detection spell, quickly forming seals with her hands and muttering something. After a while, she opened her eyes and said solemnly, "Lin Yun, I have detected that the restriction on this gate is very powerful, and it seems to be closely connected to the spiritual power structure of the entire castle. To break it, you need to find the corresponding spiritual power key, or trigger the surrounding runes in a certain order."

Lin Yun heard this and groaned inwardly. Breaking through restrictions had seemed like a daily routine, but each attempt wasn't easy, always accompanied by various difficulties and challenges. He once again carefully observed the area around the gate, hoping to find some clues to breaking the restrictions.

Lin Yun circled the castle gate, carefully examining every corner. The walls on either side of the gate were covered in intricate runes and patterns. Some were already blurred, while others could still be barely discerned. They emitted a faint glow, echoing with the fluctuations of the gate's restrictions, as if hinting at something.

At the bottom of the wall on the right side of the gate, Lin Yun found a small depression with some tiny runes engraved on it. These runes were different from the runes in other places. They emitted a faint blue light and were particularly eye-catching against the backdrop of the rune light.

"Su Yao, there is a depression here. The runes inside seem a bit special. Come and take a look." Lin Yun shouted.

Su Yao heard this and hurried over. The two of them squatted down and carefully observed the runes. Lin Yun found that the shape and arrangement of these runes seemed to imply a certain order, and the blue light they emitted seemed to have some kind of echo with the light of the runes around the gate.

"These runes are not simple. I think they may be the key to breaking the restriction of this gate." Lin Yun stood up and continued to look at the runes, trying to find some clues from their shape, arrangement and the light they emitted.

Su Yao also came closer to observe carefully. She gently placed her hands on the runes, trying to sense the flow of spiritual energy. After a while, she said, "Lin Yun, I feel that these runes seem to be releasing spiritual energy according to a specific rhythm, and this rhythm seems to be related to the spiritual energy structure of the gate restriction. However, I am not sure what the specific connection is."

Lin Yun's heart skipped a beat when he heard this. He squatted down again, carefully comparing the differences between the runes and the changes in the strength of the spiritual energy they emitted. Suddenly, he noticed that the flashing frequencies of several of the runes would briefly synchronize after a period of time, as if transmitting some kind of signal.

"Everyone, pay attention to the flashing frequency of these runes. I think there may be something interesting here. Maybe if we operate or trigger something according to this frequency, we can break the restriction of this gate." Lin Yun said.

Upon hearing this, everyone focused their attention on the runes, carefully observing their flashing light.

Lin Yun decided to try triggering the runes according to their flashing frequencies to see what effect it would have. He took a deep breath, then gently touched the runes one by one in the order he had observed, the interval between each touch strictly following the synchronized frequency of the flashing lights.

When he touched the last rune, the light around the gate suddenly flickered, then gradually dimmed, and the powerful restrictive force disappeared.

"Success!" Lin Yun shouted excitedly. He couldn't wait to push open the huge wooden door to see what was inside.

As the gate slowly opened, a stale atmosphere, mixed with a faint fluctuation of spiritual energy, washed over him. The castle was dimly lit, with only a few rays of sunlight filtering through the cracks in the high windows, casting patches of light and shadow on the ground.

Lin Yun walked in cautiously, and Su Yao followed closely behind him. They found themselves in a spacious hall. The floor of the hall was paved with huge stone slabs, which were engraved with various patterns and runes. These patterns and runes also emitted a faint light, as if telling the history of the castle.

Ancient statues were placed around the hall. These statues were of various shapes, some humanoid, some mythical beasts. They were lifelike, as if guarding the castle. However, Lin Yun always felt that there was something wrong with these statues. Their eyes seemed to be silently watching them, which made him feel uneasy.

"It feels weird inside this castle. It's like these statues are staring at us." Lin Yun whispered to Su Yao.

Su Yao also frowned slightly and said, "Well, I feel the same way. We'd better be careful."

With that, the two continued walking deeper into the hall, always on guard, ready to deal with any danger that might arise.

Lin Yun and Su Yao walked slowly in the hall. With every step they took, they could feel the runes on the stone slabs under their feet trembling slightly, as if responding to their arrival.

When they reached the center of the hall, they suddenly heard a slight creaking sound, as if an ancient mechanism was slowly starting up. Startled, Lin Yun immediately stopped and looked around warily.

"Su Yao, be careful, it seems like a mechanism has been triggered!" Lin Yun shouted in a low voice.

Su Yao also became nervous. She quickly formed seals with her hands, ready to cast a defensive spell at any time.

At this moment, they discovered that the statues around the hall seemed to be moving. Those statues that had originally seemed to be static actually began to move slowly. Although their movements were a little stiff, they carried an unquestionable majesty as they slowly walked towards Lin Yun and Su Yao.

"How come these statues come to life?!" Lin Yun shouted in surprise. He clenched the sword in his hand, ready to face the upcoming battle.

He secretly groaned inwardly. He had thought he would find some clues after entering the castle, but he hadn't expected to encounter such a strange thing right after entering. These statues looked difficult to deal with, and they seemed to be emitting a powerful spiritual energy fluctuation. They must have extraordinary strength.

Su Yao was also on high alert. She cast auxiliary spells to enhance Lin Yun's defense and attack power, and at the same time she was also prepared to deal with the attack.

The statues that came to life launched their attack without any pause.

The humanoid statues brandished their weapons, some holding swords, others shields, slashing fiercely at Lin Yun and Su Yao. Each blow sent a whistling sound, demonstrating their immense power. The mythical beast-like statues opened their maws, emitting streams of multicolored light that shot towards the two like sharp arrows, so fast that the two barely had time to react.

Lin Yun unleashed a series of sharp sword energies, attempting to block the incoming blows. However, when his sword energy collided with the statues' weapons, only a dull thud was heard, and the statues' attacks were not significantly weakened. He was secretly shocked. These statues had such strong defenses that ordinary attacks seemed to have little effect on them.

Su Yao, in the back, was doing her utmost to maintain the spiritual shield while continuously casting auxiliary spells to restore Lin Yun's spiritual energy. Her forehead was already covered with beads of sweat, and her hands were forming seals at an increasingly faster rate, but the rate of spiritual energy depletion was still making her anxious. She thought to herself, this can't go on. She had to find the weakness of these statues.

In this fierce battle, Lin Yun struggled to resist the statues' attacks while carefully observing their every move. He knew that if he wanted to survive in this desperate situation, he had to find the flaws in these statues.

Suddenly, he discovered that whenever the statues launched an attack, certain parts of their bodies would experience brief, erratic fluctuations of spiritual energy. For example, after a humanoid statue swung its weapon to attack, a faint, unstable flicker of spiritual energy would appear around its arm joints; after a mythical beast-like statue emitted light, a similar erratic fluctuation of spiritual energy would appear around its eyes.

"Could this be their weakness?" Lin Yun's heart stirred, and a glimmer of hope flashed in his eyes. He decided to observe for a while longer to confirm his guess.

So, he deliberately made some provocative movements to provoke the statues to attack even more frantically. Sure enough, after each attack, the spiritual energy fluctuation disorder in those parts would reappear.

"Su Yao, I seem to have found the weakness of these statues! After they attack, some parts of their bodies will experience chaotic fluctuations in spiritual power. Let's try concentrating our strength on attacking that part!" Lin Yun shouted loudly, with a hint of excitement in his voice, as if he had seen a ray of light in the darkness.

Su Yao was cheered up when she heard this, and immediately responded: "Okay, Lin Yun, I will cooperate with you to the best of my ability!"

At this time, although the battle was still intense and fierce, a glimmer of hope ignited in the hearts of both of them, thinking that perhaps they could use this to turn the unfavorable situation around.
