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

Meanwhile, Lu Lingxi Yao was dealing with the guards of the Immortal Doctor's Dock. With her agile movements and powerful spiritual energy, she was outmaneuvering the guards.

"Damn it, this girl is too slippery, I can't catch her at all!"

"Don't let her get near the Tomb of the Dead!"

"..."

The guards were furious, but there was nothing they could do.

Just then, a figure suddenly appeared behind Lu Lingxi Yao and struck her back with a palm. She reacted quickly, dodging the blow by moving to the side. Then, upon closer inspection, she realized that the person who attacked her was the patrolman of Immortal Doctor's Dock.

"Little girl, who are you? How dare you trespass into the forbidden area of ​​my Immortal Healer's Dock!" the inspector shouted sternly.

"Who I am is not important. What is important is that I have seen through your Immortal Doctor's Den's conspiracy," Lu Lingxi said coldly.

"A conspiracy? What conspiracy?" the inspector asked, feigning composure.

"Stop pretending. I know all about how you used the Yellow Spring Root to control spiritual energy and cultivate forbidden demonic arts," Lu Lingxi said.

The inspector's expression changed slightly, but he quickly regained his composure: "Little girl, what nonsense are you spouting? My Immortal Healer's Village is a reputable and righteous sect, how could we possibly do such a thing?"

"Whether it's nonsense or not, you know it in your heart," Lu Lingxi said. "Hand over the key, and I might spare your life."

"A key? What key?" The inspector continued to play dumb.

"Stop pretending, this is the key to opening the secret passage to the Tomb of the Underworld," Lu Lingxi said.

A flicker of panic crossed the inspector's eyes, but he remained defiant: "I don't know what you're talking about."

"Since you refuse to hand it over, don't blame me for being impolite," Lu Lingxi said.

She flashed forward and charged towards the inspector, and the two instantly engaged in battle.

The inspector was quite strong, a cultivator at the Spirit Sea Realm, but still a step behind Lu Lingxi.

Lu Lingxi's attacks were fierce and swift, each move containing powerful spiritual energy, leaving the inspector overwhelmed.

"Damn it, how can this girl be so strong?" the inspector thought to himself in surprise.

He originally thought that Lu Lingxi Yao looked young and her cultivation level should be at the Gathering Spirit Realm, so he could easily defeat her with a flick of his finger. He never expected that her strength would far exceed his expectations.

"This can't go on any longer; we must finish this quickly," the inspector thought to himself.

He gritted his teeth and took out a magical artifact from his storage ring. It was a long, jet-black sword that exuded a chilling aura.

"Little girl, you forced me to do this!" the inspector roared, brandishing his long sword and slashing at Lu Lingxi.

Lu Lingxi felt the dangerous aura emanating from the long sword and dared not be careless. She dodged the blow with a swift movement.

"boom!"

The long sword struck the ground with a loud thud, leaving a deep crack in the ground.

"What a powerful knife!" Lu Lingxi was secretly amazed.

"This sword is called the 'Black Fiend Blade,' the most prized treasure of my Immortal Doctor's Village. Countless innocent souls have died by this blade, and today, you will be one of them!" The inspector sneered, brandishing the Black Fiend Blade and attacking Lu Lingxi Yao once again.

Lu Lingxi Yao dared not take the attack head-on, and could only dodge it constantly with her agile movements.

"This can't go on. We have to find a way to take his knife away," Lu Lingxi thought to herself.

As she dodged, she searched for an opportunity. Suddenly, she noticed an opening when the inspector swung his sword. "Now!"

A glint flashed in Lu Lingxi's eyes. She moved swiftly, becoming a blur, and instantly appeared behind the inspector. She reached out her right hand and grabbed the inspector's wrist, which was holding a knife.

"Let go!"

Lu Lingxi shouted and suddenly exerted force, "Crack!" With a crisp sound, the inspector's wrist was broken by Lu Lingxi.

"what!"

The inspector let out a scream as the Black Fiend Blade flew from his hand. Lu Lingxi caught the blade and swung it back at the inspector's neck.

"Pfft!"

A human head flew into the air, blood gushing out. The inspector was dead!

Lu Lingxi put the Black Fiend Blade into her Kunlun Ring and then quickly headed towards the cave.

At this moment, Zhuque, Huanyue, and Huanying had found the key. "Master, we found the key!" Huanyue said excitedly.

"Great, let's go!" Lu Lingxi said.

The four quickly left the cave and headed towards the secret passage to the Tomb of the Underworld. Following the route provided by Bai Xiaochen, they passed through a dense forest and arrived at a secluded cliff.

"This is it," Bai Xiaochen said.

He walked to the cliff face and inserted the key into a groove.

With a soft "click," a stone door appeared on the mountainside.

"Go inside quickly!" Lu Lingxi said.

The four quickly entered the stone gate, which slowly closed...
