As soon as I put it on, I met a sickly man

Ding Chen took a deep breath and reached out to push the secret door that was emitting a faint light.

However, a powerful force suddenly rebounded and knocked him back several steps.

He stumbled to his feet, a paralyzing pain shooting through his arm.

Xiaoxuan screamed, hurried forward to support him, and carefully checked his injuries.

"Are you okay?" she asked worriedly, her eyes fixed on the strange secret door.

The surface of the secret door was as smooth as a mirror, with strange runes faintly flowing through it, emitting a heart-pounding aura.

Xiaoxuan reached out and touched it lightly, and felt a cold touch at her fingertips, as if she had touched a piece of thousand-year-old ice.

She immediately realized that there was some powerful restriction on this secret door.

"This should be an ancient sealing technique," the accompanying mystic pushed his glasses on the bridge of his nose and said in a serious tone, "It requires solving the corresponding puzzle to open it." He squinted his eyes and carefully observed the complex runes on the door, trying to decipher the mystery contained in it.

While observing, the scholar recorded on the parchment scroll he carried with him, muttering to himself.

After a moment, he raised his head, pointed at one of the special symbols and said, "I think this symbol is the key. We need to find the corresponding item to unlock the seal."

"Wait," Yingfeng, who had been silent all the time, suddenly spoke, his voice low and hoarse, "Are you sure? Could this be a trap?" His sharp eyes swept across the secret door, and he felt vaguely uneasy in his heart.

In his opinion, the appearance of this secret door was too abrupt, and it might hide a greater danger.

"A trap?" The scholar frowned in displeasure. "I've studied ancient culture for many years, but I've never seen such a sophisticated sealing technique. How could this be a trap?"

"Better safe than sorry," Yingfeng said firmly, "We can't take any risks lightly. If the solution is wrong, it could lead to more serious consequences."

The two of them each held their own opinion and the argument continued.

Ding Chen stood aside, frowning, unable to make a judgment for a moment.

Xiaoxuan gently pulled his sleeve and whispered in his ear, "I..." Xiaoxuan suddenly thought of the strange symbols she had seen on the cave murals before. They were surprisingly similar to the runes on the secret door!

Her heartbeat quickened, and she excitedly grabbed Ding Chen's arm, pointing to the rubbings of the mural and the parchment scroll in the scholar's hand and saying, "Perhaps...perhaps we can combine the symbols on the mural to decipher the seal of the secret door!"

At first, scholars were a little disdainful. What could a folk doctor know about ancient culture?

But when he carefully compared the symbols pointed out by Xiaoxuan with the runes on the secret door, his expression gradually became solemn.

Those seemingly chaotic symbols, after Xiaoxuan's explanation, actually formed a unique code!

He was shaking with excitement and exclaimed: "Brilliant! Brilliant! Why didn't I think of that?"

Following Xiaoxuan's idea, the scholar re-deduces the solution and instructs Ding Chen to embed a special crystal into the groove on the secret door in a specific order.

As the last crystal was inserted, the secret door made a low roar and slowly opened inward.

An ancient and mysterious aura blew over them, and everyone couldn't help but hold their breath.

General Lin and Ying Feng subconsciously tightened their weapons and watched the scene behind the secret door vigilantly.

"Miss Xiaoxuan is so smart!" General Lin praised sincerely. Even the usually stern Yingfeng nodded slightly, with a hint of admiration in his eyes.

Xiaoxuan felt a little embarrassed by the compliment and lowered her head shyly.

Ding Chen proudly put his arm around Xiaoxuan's shoulders and whispered in her ear, "I knew my Xiaoxuan is the best."

When the secret door was fully opened, a huge underground space appeared before everyone.

The space was filled with all kinds of strange-shaped objects and crystals emitting faint light, and the air was filled with a strange fragrance.

Just as everyone was about to go in to find out what was going on, an invisible ghost suddenly appeared in the center of the space.

It let out a sharp and piercing whistle, the sound piercing everyone's eardrums like a sharp blade, giving them a splitting headache.

Ding Chen covered his ears tightly...

Ding Chen covered his ears tightly. Xiaoxuan's painful expression made him feel heartbroken.

He endured the piercing headache, held Xiaoxuan tightly in his arms, and used his body to shield her from the invisible sonic attack.

Xiaoxuan trembled in his arms, her face pale, but she held his sleeves tightly, her eyes full of dependence.

Yingfeng's body was as fast as lightning, and the dagger cut through the air, but went straight through the ghost's body without causing any damage.

He frowned. This invisible enemy was more difficult to deal with than any opponent he had ever encountered.

General Lin roared and swung his sword. The sword wind was fierce, but he still couldn't touch the ghost at all.

He had been on the battlefield many times, but he had never seen such a strange enemy, and he couldn't help feeling a little nervous.

The mystic watched carefully from the side, his eyes behind the lenses sparkling with wisdom.

"This ghost isn't a physical entity, but rather composed of some kind of energy!" He pointed to a giant crystal in the center of the space and said with certainty, "The source of that energy is right there!"

Upon hearing this, Ding Chen fixed his eyes on the crystal that was emitting a faint light.

Without time to think, he picked up a stone and smashed it at the crystal with all his strength!

The stone hit the crystal, making a crisp cracking sound.

The crystal shattered instantly, turning into starlight and dissipating into the air.

At the same time, the ghost let out a shrill scream and disappeared.

Silence fell again, and everyone breathed a sigh of relief.

Xiaoxuan's face gradually regained its rosy complexion. She looked at Ding Chen gratefully, her eyes full of tenderness.

The crisis was resolved and everyone began to explore this mysterious space carefully.

The various strange-shaped objects and crystals emitting faint light dazzled them.

Suddenly, Ding Chen found an ancient book in a corner.

The cover of the book is badly damaged, but you can still vaguely see some strange symbols engraved on it.

He picked up the book carefully and opened it gently.

The words on the pages were something no one had ever seen before, like a heavenly book.

The mystic scholar came forward and carefully examined the words on the book, frowning and muttering to himself: "This... this is..." He suddenly stopped, raised his head abruptly, and stared at the book in Ding Chen's hand with burning eyes, "Could this be... the legendary..."
