In just a few breaths, the Flying Wheel Spiritual Treasure flew out of the Silver Mountain Range, continuing to race forward. In no time, it reached another volcanic peak surrounded by scarlet flames.

As Wu Yu and the other demons stepped off the Flying Wheel, they heard several crisp "crack" sounds. This top-level spiritual treasure suddenly exploded mid-air, shattering into countless fragments that fluttered down into the volcano's lava.

Wu Yu didn't seem distressed at all by this. With a flip of his right palm, he took out a talisman and crushed it.

A few breaths later, a mass of scorching flames instantly flew out from the volcano below, landing in front of Wu Yu.

From within the flames came the voice of the Great Sun Glaze Flame: "You got here quickly, it seems the plan is going smoothly."

"So far, so good. How's your preparation coming along?" Wu Yu asked, with a hint of concern in his tone.

"Almost done. I just need to absorb a little more Fire Spiritual Power, give me an hour," the Great Sun Glaze Flame replied.

Wu Yu frowned slightly and said, "The plan is urgent now. I can only wait for you for a quarter of an hour."

"Alright, I'll hurry," replied the Great Sun Glaze Flame, with a tone of slight resignation.

Wu Yu nodded, waved away the flames in front of him, and then sat in a meditative position in the void.

Except for Xuan Ye, all the other Demon Kings, including the Black Bear King, were visibly surprised, evidently full of curiosity about the impending plan.

"Your Majesty, at this stage, can you tell us the plan?" The Electric Roc King couldn't help but ask.

Wu Yu looked up towards the distance, in the direction of White Emperor City.

Her eyes flashed with determination and resolve, and she spoke slowly: "Of course. I didn't tell you before because I feared you might be captured and Soul Searched, which would lead to a leak of the plan. Now, everything will finally end..."

...

Beneath the Silver Tower, within the deep and dark cave.

As Sima Changqin and the others stepped into this underground world, beams of Forbidden light slashed towards them like swords, catching them off guard.

None present were ordinary people. They immediately cast spells to block the incoming Forbidden lights one by one.

After a brief panic, the group quickly regained their footing, and their eyes gradually adjusted to the dimness inside the cave.

"The World Tree? This tree is so enormous, it's beyond imagination!" someone exclaimed.

"And these Magic Arrays, their complexity has reached the pinnacle of a seven-level Magic Array!" someone else added, full of astonishment in their voice.

Even someone as composed as Sima Changqin couldn't help but show a look of surprise.

All those present were well-informed, yet the sight before them still left them astonished.

Among the crowd, Nan Shangfeng quietly observed the World Giant Tree, a flicker of light in his eyes that soon returned to calmness. It seemed he was contemplating something.

Meanwhile, in mid-air in the cave, Jie Cha's eyes were wide open with anger, with countless blue lights flashing around him.

He activated over a dozen seven-level Magic Arrays in the cave, all aimed at Su Wu.

The lights from those Arrays flickered with formidable power, as if they wanted to tear the entire cave apart.

However, any attacks that fell upon Su Wu were devoured by the Heavenly Cicada Black Qi surrounding him.

The black qi seemed to have an endless devouring power, and no attack could cause it any harm.

Even though those Forbidden attacks couldn't harm Su Wu, the constant consumption restricted the Heavenly Cicada Black Qi within a certain range, unable to overflow.

Both sides were locked in a mutual stalemate, seemingly engaged in a silent contest.

"Let's bypass them, we don't need to involve ourselves in their conflict," Sima Changqin quickly assessed the situation and said calmly.

His words immediately gained the agreement of the others, and they all concealed themselves, intending to slip past along the cave wall while the two engaged combatants remained unaware.

Just as they started moving, Su Wu in mid-air suddenly turned his head to look at them.

A cold smile flashed across his eyes, as if he'd spotted something interesting.

"Heh, you arrived just in time, I was just in need of puppet reinforcements!" Su Wu's lips curled into a cold smile as he raised his hand and waved.

Instantly, a black qi Long Dragon shot out like an arrow, rushing straight towards Sima Changqin and the others.

Seeing this situation, Jie Cha immediately activated a Wood Attribute seven-level Magic Array to intercept.

Dozens of emerald giant trees appeared out of nowhere, seemingly alive, swaying elegantly in the void.

Each giant tree was entwined with clusters of azure Lei Guang, rumbling with thunderous sounds. It was the purest Yimu Divine Thunder, containing the ripple of the Power of Dao.

Dozens of giant trees seemed like dozens of arms, smashing toward the black qi Long Dragon from all directions, causing even the void to stir, as if an invisible force was pressing down on everything.

Yet the black qi Long Dragon seemed to ignore all attacks, continuing its charge towards Sima Changqin and the others.

At the critical moment when everyone was holding their breath, the black qi Long Dragon suddenly accelerated, splitting into over a dozen streams like a crafty Spiritual Snake, deftly weaving through the gaps between the green giant trees.

In an instant, thunderous roars echoed throughout the cave; the majority of the black qi was pushed back by the Yimu Divine Thunder released by the giant trees. However, five streams of black qi ghostly slipped through, unstoppable, lunging at Sima Changqin and the others.

Sima Changqin and the others did not expect Su Wu to suddenly launch an attack on them. Seeing five streams of black energy rushing towards them, they hurriedly summoned their respective spiritual treasures to prepare for the enemy.

In an instant, the air was filled with roaring sounds as various spirit lights flashed wildly, clashing fiercely with the five streams of black energy.

These five streams of black energy dragons were exceptionally tenacious. Even though they were shattered by the combined efforts of the group, the scattered black energy seemed to possess intelligence, deftly slipping through the gaps between the spiritual treasures and rushing directly at their bodies.

The group was shocked, hurriedly forming spell seals, either raising spiritual treasures or employing other protective divine powers.

The black energy, however, was unusually bizarre; whether it was the protective light rings formed by spiritual treasures or other protective divine powers, they were instantly corroded and penetrated upon contact with the black energy.

Sima Changqin and the others' expressions changed drastically, finally witnessing the terrifying power of the Heavenly Cicada Black Qi.

They wanted to dodge, but it was already too late as the black energy struck them and rapidly invaded their bodies.

The group felt their bodies paralyzed instantly, unable to move even a finger.

Immediately, their bodies began to swell rapidly, as if inflated, resembling the scene when Yuan Ming was invaded by the Heavenly Cicada Mother Qi.

The spiritual energy between heaven and earth seemed to be summoned by something, frantically pouring into their bodies, causing their cultivation to soar rapidly in a short time.

Despite this anomaly, no one felt any joy.

Their faces were filled with pain, and their swollen bodies seemed on the verge of exploding.

The frantic pain tormented their minds, causing them to quickly lose consciousness, their eyes gleaming with bestial blood light, as if about to transform into wild beasts.

Among them was Nan Shangfeng.

His cultivation rapidly reached the peak of Returning Void with the help of the Heavenly Cicada Black Qi, and his body swelled to several meters in height, with blood vessels bulging alarmingly.

At this moment, the void not far in front of Nan Shangfeng suddenly rippled, and a thick green-gray tree root emerged from thin air, quickly wrapping around him and dragging him into the void.

Mere moments later, the root brought Nan Shangfeng into a silver space.

As soon as the green-gray root set Nan Shangfeng down, more roots emerged from thin air, piercing into his body and exerting a force of suction.

The black energy within Nan Shangfeng's body was swiftly absorbed by the suction of the roots, and his body gradually returned to its original form.

"Indeed, the World Tree is the nemesis of the Heavenly Cicada Black Qi."

A vague face appeared on the green-gray tree root, belonging to Yuan Ming.

He had already begun to control the World Giant Tree, and upon seeing Nan Shangfeng's dire state, he immediately used the roots of the World Tree to rescue him from afar.

Yuan Ming carefully observed Nan Shangfeng, and suddenly his expression shifted as if he had sensed something.

Soon after, a slender tree root shot out from the void, silently entering Nan Shangfeng's Dantian.

A moment later, a look of surprise appeared on Yuan Ming's face.

Despite being eroded by the Heavenly Cicada Black Qi, Nan Shangfeng had unexpectedly gained some benefits.

His cultivation did not regress; he remained steadily at the peak of Returning Void.

More importantly, his previously damaged Spirit Root had considerably recovered.

Recalling his earlier promise to Nan Shangfeng, Yuan Ming couldn't help but feel a bit emotional.

He had promised to help restore his Spirit Root, but due to various reasons, this had been delayed until now.

Seeing Nan Shangfeng's Spirit Root recovering on its own, Yuan Ming felt much relieved, knowing it would now be much easier to repair.

He took a deep breath, carefully separating a strand of Ten Thousand Wood Origin from his body, and gently infused it into Nan Shangfeng's Dantian.

Yuan Ming cautiously guided his Mana, trying to perfectly integrate this strand of Ten Thousand Wood Origin into Nan Shangfeng's Spirit Root.

After all, it was his first attempt, and Yuan Ming's technique was somewhat clumsy.

The majority of the Ten Thousand Wood Origin dispersed during the integration process, merging into Nan Shangfeng's body, washing through his Mana, with only a small part successfully merging into his Spirit Root.

Nevertheless, this bit of Ten Thousand Wood Origin was already enough for Nan Shangfeng to use.

His Spirit Root was completely restored and even showed significant advancement compared to before.

This unexpected discovery greatly pleased Yuan Ming as he hadn't anticipated the nurturing effect of the Power of Ten Thousand Wood Origin on Wood Attribute Spirit Roots to be so profound.

He resolved internally to try it on himself in the future, wondering if it could elevate his own Spirit Root to the next level.

At this moment, Nan Shangfeng's consciousness gradually awakened.

A trace of confusion first flashed across his face, but upon seeing the roots around him, he immediately recalled everything that just happened.

He quickly checked his body and displayed an uncontrollable expression of joy.

"Fellow Daoist Wan, is that you?" He pondered briefly and then stood up to salute.

"It is I." Yuan Ming's voice echoed, seeming to emanate from all directions, making it impossible to pinpoint its exact location.
