Chapter 473 Three Questions about Guarding the Treasury

He looked at his left arm and found that the light from the palm print had also dimmed, but the red lines were still there.

"We need to speed things up," Liu Wushuang said gravely. "The poison of the Netherworld Palm is not simple; we must find the antidote in the secret vault as soon as possible."

Lin Han nodded, looking into the depths of the cave: "I sense a passage over there."

"A passage?" Liu Wushuang looked at the smooth rock wall in confusion. "That's a dead end."

"Trust me." Lin Han took her hand and walked towards the rock wall.

To the average person, it is indeed a complete stone wall.

But in Lin Han's "Sky Eye" vision, there was a blurry outline on the rock wall, like a hidden door.

He reached out and touched the cold rock. Suddenly, the black light at the palm print resonated with some kind of energy on the rock wall, and the entire rock wall began to tremble slightly!

"Step back!" Lin Han pulled Liu Wushuang back a few steps.

The rocks on the cliff face moved and rearranged as if they were alive, eventually forming an arched doorway.

Behind the door is a staircase leading downwards, with walls on both sides inlaid with luminous crystals that illuminate the path ahead.

Liu Wushuang looked at Lin Han in surprise: "How did you know...?"

“Intuition.” Lin Han didn’t elaborate. “Let’s go, this path should lead directly to the secret treasure.”

The two smiled at each other and stepped into the mysterious passage hand in hand.

The steps meander downwards, seemingly leading deep into the mountainside.

No one knows what awaits them ahead, but one thing is certain—the Xuantian Sect's millennium-old secret is finally about to be unveiled to its master.

The staircase winds downwards, and the light from the crystals casts interlacing shadows in the passageway.

Lin Han could feel the stinging pain from the palm print on his left arm gradually intensifying as it went deeper, as if reminding him that the Netherworld Palm poison was spreading.

“This passage… doesn’t look like it was carved by man.” Liu Wushuang touched the smooth cave wall, which showed signs of water erosion, yet was too neat.

Lin Han's Heavenly Eye became even more acute in this confined space.

He could "see" energy flowing inside the cave walls, like the meridians in the human body, eventually converging into a powerful energy source underground.

"The entire mountain has been modified; it's a giant contraption."

At the end of the passage, a massive bronze gate suddenly appeared.

The door is carved with nine coiled dragons, their eyes inlaid with luminous crystals, and their bodies intertwined to form a complex mechanism lock.

Two stone statues stand on either side of the gate: a swordsman on the left and a scholar holding a book on the right, both lifelike.

"The Mysterious Heavenly Treasury..." Liu Wushuang's voice trembled, "We've found it!"

Lin Han stepped forward and carefully examined the mechanism lock.

All nine dragon scales are movable, so they obviously need to be pressed in a specific order.

He tried to recall the details of the map of the twin swords and the carvings in the cave, but could not find any relevant clues.

"Let me try." Liu Wushuang took a silver hairpin from her hair, inserted it into the keyhole, and gently turned it.

Her technique was extremely professional, clearly indicating she had received special training.

Lin Han was somewhat surprised: "You can do this too?"

“My master taught me. He said that the Xuantian Sect’s mechanical arts are unparalleled in the world, and we must…” Before Liu Wushuang could finish speaking, the sound of a mechanism turning suddenly came from inside the lock.

Her expression changed drastically: "Oh no, it's a countermeasure! Retreat!"

The two retreated rapidly, when suddenly the dragon's mouth on the door opened and shot out several poisoned arrows!

Lin Han wielded his twin swords to parry, while Liu Wushuang's slender sword moved like a snake, precisely striking down any arrows that slipped through the net.

After the rain of arrows, the ground in front of the gate suddenly sank, revealing a deep pit filled with sharp spikes.

If they hadn't retreated in time, they would have already been infected.

"What a formidable mechanism." Lin Han was still shaken.

Liu Wushuang shook her head: "This isn't the style of the Xuantian Sect. Their internal mechanisms are primarily for testing, not for killing. This seems like... a defensive measure added later."

Just then, an aged voice suddenly echoed in the cave: "Who goes there? How dare you trespass into the Xuan Tian Secret Treasury!"

The sound seemed to come from all directions, making it impossible to pinpoint its source.

Lin Han shielded Liu Wushuang behind him and announced loudly, "I am Lin Han, son of Ye Qingchen, here to inherit the Xuan Tian Sect's legacy!"

After a moment of silence, the voice rang out again, tinged with sarcasm: "Sect Leader Ye's son? Do you have proof?"

Lin Han raised the Azure Frost Sword: "This sword is my witness!"

Suddenly, the statue on the right moved!

The stone shell of the sword-wielding warrior shattered inch by inch, and an old man with white hair emerged from it.

His face was gaunt, but his eyes were as sharp as an eagle's. In his hand he held a short sword that was very similar to the Azure Frost Sword, except that the patterns on the blade were slightly different.

"The Azure Frost Sword..." The old man narrowed his eyes, "But a sword alone isn't enough. In the past twenty years, at least three people have come with this sword, all claiming to be descendants of Sect Master Ye."

Lin Han's heart skipped a beat: "They...are all dead?"

The old man didn't answer, but instead asked, "You say you are the son of Sect Leader Ye, do you know the name of the Sect Leader's wife?"

“Zhou Zhiyun.” Lin Han replied without hesitation.

This name was given to him by Lin Zhennan before his death, so that he would remember it forever.

The old man's eyes flickered slightly, but he quickly regained his composure: "Many people know this name. Second question: What is the key to the seventh revolution of the Nine Revolutions of the Mysterious Heaven?"

Lin Han pondered for a moment: "Qi circulates through the extraordinary meridians, and the spirit guards the dantian. The seventh transformation requires reversing the Yin Wei meridian, which is extremely risky, but success will open the bridge between heaven and earth."

This was his personal experience during cultivation. If it weren't for the special nature of his Xuan Tian bloodline, he would have already gone astray and become possessed by demons.

The old man nodded slightly and asked his third question: "One last question—what is the ultimate state of martial arts?"

This question left Lin Han speechless.

He recalled Lin Zhennan's teachings—those seemingly ordinary family precepts—which flashed through his mind like lightning.

“Father…” Lin Han slowly said, “Martial arts are not the way of killing, but the way of stopping war. The ultimate martial art is not about being invincible, but…” He paused, a flash of understanding in his eyes, “but about ‘protection.’”

Before he finished speaking, the flame pattern on his forehead suddenly appeared, resonating with the short sword in the old man's hand.

The two swords emitted clear, melodious sword sounds at the same time, and the patterns on their blades flowed and changed as if they were alive, eventually combining to form the same pattern!

Seeing this, the old man finally smiled.

He knelt on one knee, his voice trembling with emotion: "This old servant, Ye Shou, respectfully welcomes the young master back to his position!"

Lin Han quickly helped him up: "Senior, please rise! What happened to you..."

"This old servant is the seventh-generation guardian of the Xuantian Sect's archives, and has been waiting here for the young master for twenty years," Ye Shou said, tears welling in his eyes. "I knew the sect leader's bloodline would not be severed!"

Liu Wushuang stepped forward and bowed: "Junior Liu Wushuang, daughter of Liu Xuanfeng, greets Senior Guardian of the Archives."

Ye Shou looked her over and nodded slightly: "Protector Liu's daughter...your father is a good man."

He turned to Lin Han, "Young Master, were you struck by the Netherworld Palm?"

Lin Han rolled up his sleeves, revealing a glowing palm print: "Senior knows this poison?"
