Genius in the whole system: The useless young lady dominates the world

Above Lu Ling's residence in Yanjing City.

Despite being covered in blood, Lu Lingguihong managed to withstand the combined attacks of Lu Lingqingyue and several black-clad spiritual saints by relying on the interplay of the five elements and his exquisite swordsmanship.

However, he was no match for the many hands that were at his disposal. He had already sustained several deep wounds that exposed bone, and his spiritual energy had been largely depleted, causing his movements to gradually slow down.

Although Lu Lingyuntian tried to interfere with his grandson using his mental power, it had little effect against so many powerful figures. He could only watch helplessly as his grandson fell into a desperate situation, and he was extremely anxious.

"Lu Lingguihong, your death is near!" A sinister smile flashed in Lu Lingqingyue's eyes as she drew a jet-black longsword that exuded a dense aura of death, and stabbed it fiercely toward Lu Lingguihong's heart!

This sword strike was as fast as lightning and at a tricky angle. Lu Lingguihong was already at his limit and had no way to dodge it!

"Guihong!" Lu Lingyun's eyes widened in fury!

At this critical moment!

"call out--!"

A sharp arrow formed from demonic energy pierced through the air, arriving faster than expected, and struck Lu Lingqingyue's longsword precisely!

A crisp clang rang out!

Lu Lingqingyue's longsword was actually deflected by the force, and a tremendous force came, making her hands go numb and causing her to retreat repeatedly!

"Who goes there?!" Lu Lingqingyue was both shocked and furious, and suddenly looked up at the sky!

Suddenly, a tall and imposing figure appeared in the night sky. He was dressed in a black royal robe, with an exceptionally handsome face and deep, cold eyes that looked down upon everything below.

The person who arrived was none other than Nalan Rongzhi!

"It's you?!" Lu Lingqingyue's pupils contracted sharply as she recognized Nalan Rongzhi. A storm raged within her; how could he be here? Could it be…

Nalan Rongzhi completely ignored her. His gaze fell on Lu Lingguihong, who was covered in blood, and Lu Lingyuntian, who was extremely anxious. A subtle fluctuation flashed in his eyes.

"Those who harm them shall die!" The cold voice came from his mouth, like the pronouncement of death.

Before he finished speaking, he flashed and instantly appeared in front of a black-clad Spirit Saint who was about to ambush Lu Lingguihong. Before the black-clad Spirit Saint could react, he felt an irresistible force gripping his throat. He looked at the handsome but cold face in front of him in horror, and tried to struggle, but found that all the spiritual power in his body was imprisoned!

"Click!" There was a soft sound.

With a casual pinch, Nalan Rongzhi snapped the neck of the Spirit Saint expert, causing his body to collapse limply to the ground!

Instant kill! A Spirit Saint level expert was so easily killed by him!

The remaining black-clad Spirit Saints and Lu Lingqingyue were stunned. A chill ran from the soles of their feet to the top of their heads. The strength of the man in front of them far exceeded their imagination!

"Retreat! Retreat now!" Lu Lingqingyue made a decisive decision and let out a sharp roar. She knew that with Nalan Rongzhi there, their plan for tonight had completely failed. If they didn't leave now, they would probably all die here!

However, how could Nalan Rongzhi let them leave so easily?

"Trying to leave? Too late." A cold glint flashed in his eyes, and he raised his hand, making a grasping motion in the air!

"what--!"

Several black-clad spirit saints who were about to flee suddenly let out a scream, as if their bodies were grabbed by an invisible hand and slammed hard to the ground!

"Bang bang bang!" Like dumplings being dropped into a pot, several Spirit Saint level experts were smashed into mincemeat!

Only Lu Lingqingyue reacted the fastest. The moment Nalan Rongzhi made his move, she crushed a life-saving teleportation jade talisman, turned into a black light, and disappeared from the spot in a sorry state.

Nalan Rongzhi looked in the direction where Lu Lingqingyue disappeared, a cold glint flashing in his eyes, but he did not give chase. His main purpose was to protect the people Lu Lingxi Yao cared about.

In the blink of an eye, the Black Abyss assassins who were besieging Lu Ling's mansion were wiped out by the elite demons brought by Nalan Rongzhi.

Lu Linggui Hong looked at the man before him, who seemed like a god or demon descended to earth, and the terrifying demon warriors behind him, and was deeply shocked.

He struggled to his feet, cupped his hands in thanks, and said, "Thank you for saving me! May I ask who you are...?"

Nalan Rongzhi turned around, his gaze falling on Lu Lingguihong, then looking at Lu Lingyuntian who was being protected behind him. His tone was still cold, but it seemed to have lost a trace of killing intent. "I am here on orders."

Ordered? By whose orders? Lu Lingguihong and Lu Lingyuntian exchanged a glance, both seeing the confusion in each other's eyes.

Meanwhile, at the Holy Spirit Academy.

Despite being confined by space, Zi Sang Gu Cheng, with his powerful strength at the Spirit God realm and rich combat experience, was still able to hold his own against the men in black. Other elders and instructors from the Holy Spirit Academy had also arrived to provide support and surrounded the men in black.

Just as the leader of the men in black was about to forcibly take Zisang Gucheng away regardless of the consequences, a deafening sound of air being torn apart came from the sky!

Countless demon warriors descended from the heavens like divine soldiers, instantly joining the battle!

"Demons?!" Zi Sang Gu Cheng and the others from the Holy Spirit Academy were all shocked. How could demons be here? And judging from their appearance, they seemed to be helping them?

Nalan Rongzhi appeared silently beside Zisang Gucheng, raised his hand and waved, and a pure demonic energy shattered the spatial confinement magic weapon!

Zisang Gucheng felt a sense of relief wash over him, regaining his freedom. He looked at the demon man who had suddenly appeared before him with unfathomable aura, feeling a sense of familiarity, but he couldn't quite place where he had seen him before.

"Thank you for your help," Zisang Gucheng said, bowing. "May I ask who you are...?"

Nalan Rongzhi looked at the old man before him, whose hair was gray and whose face was serious, yet who still vaguely resembled his former master, who was somewhat rigid and protective of his own. A subtle feeling arose in his heart.

He was silent for a moment, then slowly spoke, his voice deep and strangely magnetic, "Master, how have you been?"

“Master?” Zisang Gucheng was shocked. He widened his eyes and carefully examined Nalan Rongzhi. Long-forgotten memories flooded back into his mind like a tide!

This face... though it has become more mature and aloof, the contours of its brows and eyes, that deep gaze...

"You...you are...Xinglan? Lu Xinglan?" Zisang Gucheng exclaimed in disbelief!

The boy who was forced upon him by Yao Yao, whom he initially looked down upon, but who later displayed astonishing talent and then mysteriously disappeared—he was actually…the Demon Lord of the Demon Clan?!

The amount of information was simply overwhelming. Even with his vast experience and knowledge, Zisang Gucheng felt a bit overwhelmed at this moment.

Nalan Rongzhi nodded slightly, tacitly acknowledging his identity. "The situation is urgent, we'll talk later."

He turned around, his cold gaze sweeping over the black-clad men surrounded by demon warriors. "Leave none alive."

"Yes!"

A sudden crisis was swiftly quelled by Nalan Rongzhi's thunderous intervention.

After the battle, Nalan Rongzhi ordered a portion of the elite demons to remain in Yanjing City to protect the safety of Lu Ling Mansion and Holy Spirit Academy, while he himself returned to Lu Ling Mansion.

Lu Lingyuntian and Lu Lingguihong had already treated their injuries and were waiting in the hall. When they saw Nalan Rongzhi walk in, they both stood up.

"Your Excellency..." Lu Lingyun was about to ask.

Nalan Rongzhi, however, preemptively bowed slightly to Lu Lingyuntian, offering a junior's greeting, "Grandpa."

This cry of "Grandpa" stunned both Lu Lingyuntian and Lu Lingguihong!

Nalan Rongzhi raised his head and looked at Lu Lingguihong. His tone was still calm, but no longer so cold. "Big brother."

Lu Lingguihong: "..."

Lu Lingyuntian was, after all, an old fox who had lived for many years. Looking at Nalan Rongzhi's peerless face, which bore a striking resemblance to Lu Lingxi Yao, and recalling Yao Yao's previous trip to the Demon Realm, as well as how this person addressed them... a bold guess formed in his mind.

"You...you are Yao Yao's...?" Lu Lingyun asked tentatively.

Nalan Rongzhi nodded: "I am Nalan Rongzhi, Yao Yao's fiancé."

boom!

This answer exploded in Lu Lingyuntian and Lu Lingguihong's minds like a thunderclap!

Yao Yao's fiancé... is actually the Demon Lord of the Demon Realm?!

The two looked at each other, unsure how to react.
