An emperor in his later years is summoned by his sister to save the nation's fate.

Meanwhile, in the Xuan Tian Realm, amidst the endless starry sky, an imperial chariot pulled by nine black dragons crashed through numerous spatial barriers, hurtling towards the Eternal Night Imperial Court of the Ziwei Imperial Star.

Inside the imperial carriage was a world unto itself. In the spacious and luxurious main hall, Lu Li sat with his eyes closed on a couch carved from millennia-old warm jade, his mind immersed in the strange world of Blue Star.

Just as Lu Li crushed the S-class eerie and monstrous entity with a single finger through a projection of one ten-millionth of its size.

A crisp system notification suddenly rang in Lu Li's mind.

[Ding, successful protection of the host detected, reward calculation in progress...]

[Reward: One peerless spiritual plant – Enlightenment Tea Tree!]

[System notification: This reward has been automatically sent to your system space. Please check it.]

Lu Li closed his eyes slightly, without opening them, and instead directly probed his divine sense into the system space.

In the very center of that vast, white, isolated space, stood an ancient tree, about ten feet tall, its entire body brimming with profound Daoist essence.

The trunk of this tea tree resembles a coiled dragon, and its bark is naturally engraved with dense, intricate patterns.

On the branches, dozens of tea leaves of various shapes hang sparsely. Some tea leaves are shaped like phoenixes spreading their wings, some like dragons coiling, and others like an ancient bell of chaos or a peerless immortal sword.

Around each tea leaf are tangible fragments of laws and the pronouncements of the Great Dao.

This is none other than the Enlightenment Tea Tree, a legendary treasure of enlightenment that has long since disappeared from the Xuan Tian Realm!

Even just picking a single tea leaf from the Enlightenment Tea Plantation and steeping it in water can forcefully help a cultivator enter a state of ethereal enlightenment, having an extraordinary effect on comprehending cultivation techniques and breaking through cultivation bottlenecks.

For Lu Li, who was at the Great Emperor level, this was a rare celestial treasure.

Lu Li's lips curled up slightly, and a look of satisfaction flashed in his eyes.

This cross-industry collaboration, crushing an ant in exchange for a Daoist tea tree, is truly a profitable deal.

……

The eerie origin world of Blue Star, a wasteland of eternal night.

Within the unclaimed territory, as Lu Li remotely obliterated the S-rank demon's true form, the dense, dark red mist that shrouded the core area also dissipated and receded as if it had lost its source.

The devastation was completely exposed to the air. Lu Xueyao, accompanied by a five-meter-tall starving ghost, a ghost bride in red, and a white bone demon general wielding a giant axe, began a thorough search of this core area.

Soon, Lu Xueyao's gaze was drawn to a peculiar building not far ahead.

This is a square building constructed from dark red boulders. The interior exudes a strong stench of blood, but it doesn't feel nauseous; instead, it emanates a strange energy fluctuation.

When Lu Xueyao approached within ten meters of the building, the notification sound of the National Fortune System immediately rang in her mind.

[System notification!]

[Unclaimed special building discovered; analyzing building information...]

[Building Name: Blood Pool and Flesh Forest]

[Building Grade: B]

[Building Function: When flesh and blood corpses (including the remains of slain physical entities) are placed inside, this building can automatically refine and purify them, ultimately producing pure blood crystals.]

[Blood Crystal Effects: An energy crystal with no side effects. Long-term consumption can permanently enhance the user's physical strength. When consumed during combat, it can quickly restore satiety and stamina.]

[Add it to your system inventory?]

"Great stuff!" Lu Xueyao's eyes lit up. For her, a demonic cultivator who mainly cultivates the Blood Nerve and relies on the power of blood and qi, this building that can purify strange flesh and blood to produce blood crystals is simply a tailor-made logistics station.

These blood crystals can not only replenish physical strength, but may also play a significant supporting role in the cultivation of the blood nerve.

"Put it in my backpack!" Lu Xueyao immediately chanted in her mind. As soon as she finished speaking, the huge blood pool and flesh forest in front of her turned into a stream of light and disappeared from the spot in an instant.

After putting away the Blood Pool and Flesh Forest, Lu Xueyao continued to explore. Not far ahead, she discovered a second unusual building behind a collapsed ruin.

This is an ancient well carved from pure white jade, with intricate moon totems engraved around the wellhead.

Despite the dilapidated surroundings, the well still emitted a faint, soft glow.

Lu Xueyao stepped forward.

[Building Name: Moon Well]

[Building Grade: Grade A]

Current status: Incomplete (not functional)

[Building Function (In Fully Functional): Automatically absorbs Yin energy daily, condensing to produce 5 drops of Yin Jade Liquid.]

[Effects of Taiyin Jade Liquid: A supreme healing liquid that instantly restores a high percentage of health upon consumption and can forcibly dispel and eliminate eerie curses and supernatural contamination below Grade A.]

[Warning: The current building is missing 1 Moonstone, a core component, and is therefore unusable. Would you like to add it to your inventory?]

"It's actually a Class A building!" Lu Xueyao's breathing quickened slightly. The Taiyin Jade Liquid, which can dispel strange curses, is definitely a strategic resource that can save lives in critical moments.

Although it is currently in a damaged state, it should be able to be completely repaired once the so-called "moonstone" is found.

"Take it!" Lu Xueyao took it for herself without hesitation. Just as Lu Xueyao was overjoyed to have acquired two high-level buildings in succession.

Lu Li, seated deep within her sea of ​​consciousness, had his double pupils pierce through the layers of ruins in the core area of ​​the territory, locking onto a shadowy spot in the far distance.

In Lu Li's vision, there was a strange magnetic field that could devour even the surrounding light. The regular fluctuations it emitted were far greater than the previous A-level Moon Well, and even more profound than the S-level Trickster he had just crushed!

"Xueyao, head due north. There is a special building there that seems to be far superior to an A-level building."

Lu Li's divine sense transmitted to Lu Xueyao's mind. Upon hearing this, Lu Xueyao immediately composed herself and led the three strange creatures to speed towards the due north.

Passing through the completely collapsed backyard of the lord's mansion, a special altar filled with an indescribable sense of mystery suddenly came into view.

The altar was made entirely of an unknown dark purple rock, and was octagonal in shape, as tall as a three-story building.

The altar surface was not carved with any runes, but was covered with dark red veins that pulsated like the blood vessels of a living creature.

The moment Lu Xueyao's gaze met that of the altar, she felt a "buzz" in her mind, as if an invisible hammer had slammed into her mental barrier, creating a strong mental shock that made her involuntarily take a half step back.

[A warning about the nation's fate!]

[Dangerous abandoned building discovered! Analyzing...]

[Building Name: Evil God Altar]

[Building Grade: S]

[Building Function: Sacrifices of special items related to the supernatural, such as supernatural crystals and even fresh flesh and blood, can be exchanged across dimensions for equivalent value with unknown evil gods, in exchange for generous rewards bestowed by the evil gods.]
