Su Wu faintly smiled and said, "Our identities are not something you need to know. As long as you don't interfere with our affairs, we won't inquire into the schemes between you and the Ten Thousand Demon Country. Both sides take what they need, like well water not mixing with river water, wouldn't that make everyone happy?"

Though the Great Sun Glaze Flame had doubts in her heart, seeing Su Wu and the others' determined attitude and seeming unwillingness to be her enemy, she suppressed her suspicions and continued to absorb the Fire Attribute Spirit Qi in the Soluble Cave with her eyes closed.

As Su Wu said, he still stood at the edge of the Soluble Cave, waiting quietly without any improper action.

As the Great Sun Glaze Flame absorbed, the Fire Attribute Spiritual Power in the cave quickly diminished, and the previously boiling magma gradually calmed down.

The temperature in the cave dropped rapidly, and the water level of the Magma Lake noticeably lowered.

Once the Fire Attribute Spirit Qi in the cave was fully absorbed, the Great Sun Glaze Flame slowly opened her eyes, gave Su Wu and the other two a deep look, then her figure blurred and transformed into a Golden Shadow, quickly leaving the place.

After watching the Great Sun Glaze Flame leave, Su Wu waited a moment longer, then chuckled lightly and said, "She saved us some trouble after all."

Saying this, he suddenly raised his hand and cast several spells on the magma beneath his feet.

Suddenly, a silver spirit light surged from the magma, pushing the surrounding magma aside to form a passage.

Soon after, a rumbling sound echoed as a silver-lit door slowly emerged from the magma.

With a wave of Su Wu's hand, the door seemed pulled by some mysterious force, opening with a boom to reveal a hidden staircase.

This staircase seemed to lead into endless depths, each step emitting a faint silver light, as if formed from condensed stars.

Su Wu, Su Yingxue, and Hei Lian descended this staircase on foot, quickly arriving at a room flickering with silver light.

The room was empty, save for a Jade Box floating in mid-air, its body surrounded by complex runes emitting a mysterious aura.

Su Wu stepped forward and cast several spells on the Jade Box with a raised hand.

As the spells landed, those runes seemed drawn by a certain force, shattering and dissipating into starlight in the air.

The Jade Box then flew out with a "whoosh," landing steadily in Su Wu's hand.

Su Wu gently opened the Jade Box, revealing a key of ancient form lying quietly inside.

This key was a shade between blue and gray, though only half a foot long, it exuded an aura of age and weight, as if containing endless years and secrets.

If Yuan Ming were here, he would immediately recognize the extraordinary nature of this blue-gray key—its material, precisely from the legendary World Tree.

"Finally found it."

Su Wu's lips curled into a satisfied smile as he reversed his hand to put away the key.

He then left the Soluble Cave with Su Yingxue and Hei Lian, speeding toward the direction of the Silver Tower.

Their figures quickly disappeared at the cave's exit, leaving behind the slow-closing door and the room filled with silver light, quietly shimmering in the darkness, as if telling some unknown secrets.

...

Near the Silver Tower.

Another day passed, and the final tenth Boarding Order remained without news.

Everyone's emotions were like a lake surface swept by wind, waves rising and falling, hard to calm.

"Could it be that the final Boarding Order is really trapped in some hidden corner of the Three Realms Immortal Boat, untouched to this day?" Long Hou, with furrowed brows, said thoughtfully.

Jin Chen heard this and gently shook his head, "It's possible. Let's wait a bit longer. Wang Fulong and the Sunset Sect people have yet to appear, perhaps they are searching for this final Boarding Order with all their might."

After hearing this, Long Hou unconsciously glanced at Yuan Ming.

He appeared undisturbed, as if the external turmoil had nothing to do with him, causing an indescribable emotion to rise in Long Hou's heart, then he fell silent.

At this moment, Wulu was sitting cross-legged beside Yuan Ming, originally intending to explore outside, but Purple Extreme Tai Sui, after devouring several poisonous spiritual materials, showed signs of advancing to Level 4 Middle Stage.

Wulu simply gave up his thoughts of going out, closing his eyes and focusing, carefully sensing the changes in Purple Extreme Tai Sui, just in case.

Long Hou's gaze turned again to Wu Yu, solemnly asking, "Fellow Daoist Wu Yu, your Ten Thousand Demon Country was the first to enter this Three Realms Immortal Boat space, and you were the first to reveal the truth of this space to us. So, regarding the whereabouts of this final Boarding Order, do you truly know nothing, or are you secretly plotting something?"

"Though our Ten Thousand Demon Country was here first, the area explored was very limited. Regarding the whereabouts of the final Boarding Order, we indeed have no clue. If Fellow Daoist doesn't believe, I can swear by my Heart Demon." Wu Yu replied solemnly upon hearing this.

Seeing Wu Yu speak so decisively, though Long Hou had doubts, he didn't continue to press.

"Fellow Daoist Qin Mo, among the fellow Daoists gathered here, you are the most knowledgeable, can you think of any way to break through this situation?" Suddenly, Wu Yu looked at Sima Changqin.

"In recent days, I've devoted myself to studying the Boarding Order I possess and have indeed gleaned some insights. The Forbidden within this Boarding Order is quite unique, seemingly having a subtle resonance with other Boarding Orders," Sima Changqin said, slowly taking out a Boarding Order from his sleeve, its surface gleaming with radiant colors, as if concealing endless secrets.

"What can this resonance do?" Long Hou asked, a bit curious.

Sima Changqin smiled faintly and said, "I once learned a Secret Technique that can actually drive the Forbidden within the Boarding Order and perhaps sense the location of other Boarding Orders. However, this Secret Technique requires multiple Boarding Orders to work in concert for it to be performed. Therefore, I have a proposal: lend me your Boarding Orders temporarily, and perhaps we can sense the whereabouts of the final Boarding Order."

Upon hearing this, Long Hou's face immediately changed, and he said sternly, "What? Hand over the Boarding Order to you? This Boarding Order concerns our major affairs; how can it be handed over lightly?"

"Fellow Daoist Qin Mo, this matter is of great importance and warrants careful consideration," Wu Yu said noncommittally.

Master Tantai and Jin Chen also remained silent, clearly holding a reserved attitude towards this matter.

Seeing this, Sima Changqin nonchalantly put away the Boarding Order in his hand and said indifferently, "Since you are all unwilling to help, then let us continue to wait here. Perhaps in a month or two, the final Boarding Order will fly to us on its own."

Upon hearing this, the faces of Long Hou, Wu Yu, and the others all changed slightly. They all knew that coming to this Fire Rock Desert to seek treasure had already consumed quite some time, and there was indeed not much more time to waste here.

Master Tantai was the first to break the silence. He flipped his palm and took out two Boarding Orders, saying, "Lord Qin Mo's words are very reasonable. I am willing to hand over the Boarding Orders. However, I request Lord Qin Mo to cast the spell here to avoid unexpected incidents."

Jin Chen hesitated for a moment but also took out a Boarding Order, holding it in his hand while glancing at the others around.

Seeing this, Long Hou reluctantly took out a Boarding Order as well.

Yuan Ming pondered for a while, and then, without changing his expression, took out a Boarding Order.

Everyone's eyes then turned to the people from the Ten Thousand Demon Country, and Wu Yu smiled faintly, saying, "Since everyone is so united, our Ten Thousand Demon Country will not lag behind."

As she spoke, she turned over her palm, and a Boarding Order appeared in her hand.

However, when Sima Changqin saw the Boarding Orders in his hand, he couldn't help but frown. He found that with the Boarding Orders handed over by everyone and his own, there were only seven.

"It seems that someone here is hiding two Boarding Orders and hasn't handed them over. Is it necessary to resort to such cleverness at this time?" Sima Changqin's voice carried a hint of coldness.

The people present looked at each other, yet no one spoke.

"Lord Qin Mo, I suspect those two Boarding Orders might not be in our hands," Jin Chen said.

"What does that mean?" Sima Changqin's eyes shifted.

"Among everyone here, I was probably the first to arrive, and before I came, the number on the Round Mirror was already two," Jin Chen said.

With these words, the tense atmosphere in the room began to ease.

"Could it be that someone got ahead and entered the Silver Tower early? Or perhaps that person came and left, and is not here at this moment?" Long Hou's brow furrowed tightly, filled with doubt.

Master Tantai turned his gaze to Sima Changqin, and with a hint of urgency asked, "Fellow Daoist Qin Mo, with the number of Boarding Orders we currently have, is it sufficient to perform your Secret Technique?"

Sima Changqin nodded slightly, saying in a deep voice, "Seven Boarding Orders should be worth a try."

Upon hearing this, Master Tantai's face lit up with joy, and he laughed, "That's good. With the Secret Technique performed, surely we can find out the whereabouts of the remaining three Boarding Orders."

Everyone nodded in agreement, even Yuan Ming nodded slightly, expressing his approval.

Seeing this, Sima Changqin reminded everyone, "Then please take out your Boarding Orders, and later, as I cast the spell, everyone must inject Mana into your Tokens."

With that said, he was the first to raise his Boarding Order, and Mana surged out.

His hands quickly formed Seals, and he muttered words, obscure syllables continuously spilling out.

As the spell was cast, the Boarding Order in Sima Changqin's hand instantly burst forth with dazzling silver light, rapidly expanding into a silver ball of light several feet in size, completely enveloping his left hand.

Seeing this, the others also poured Mana into their Boarding Orders. In no time, seven silver balls of light floated in their hands, and the brilliant light reflected on them made their robes glimmer, as if clad in silver War Armor.

"Rise!"

With a gentle shout from Sima Changqin, beams of light simultaneously rose from the silver balls in everyone's hands, intersecting in the air to form a larger ball of light.

Under their watchful eyes, the ball of light slowly ascended and began to drift southeast.

"Great, the Secret Technique is indeed effective!" Seeing this, everyone couldn't help but feel joyful.

However, just as the silver ball was about to fly into the distance, it suddenly trembled and then exploded in mid-air. The silvery light spilled down like water, enveloping everyone outside the tower, forming a silver ball of light.

With a cry of shock, they instinctively wanted to resist, but the surrounding silver light suddenly became dense, as if an invisible force was pulling them into the air, directly crashing into the Round Mirror on the Silver Tower.
