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

Finally, they arrived at a shop called "Nine Nether Pavilion". This shop was different from other places. There were no vendors hawking their wares at the entrance, nor were there a dazzling array of goods. There was only a black sign with gold lettering that read "Nine Nether Pavilion", which exuded a mysterious and eerie atmosphere.

"This is the Nine Nether Pavilion," Huan Yue said softly. "Let's go in and take a look."

Lu Lingxi and Yao nodded, and the four of them entered the Nine Nether Pavilion. As soon as they entered, they felt a chilling aura rushing towards them, as if they had entered another world.

The shop was dimly lit, with only a few eerie green lanterns emitting a faint glow. The shelves around the shop were filled with all sorts of strange things: dried herbs, odd bones, and some unknown liquids, all emitting eerie smells.

Deep inside the shop, an old man in a black robe sat behind the counter, his face hidden under his hood, making it impossible to see his features. On the counter were three root-like plants, exuding an eerie aura.

"Could this be the Root of the Underworld?" Lu Lingxi asked as she walked to the counter.

“Indeed.” The old man in black robes spoke in a hoarse and deep voice, as if squeezed from the depths of his throat. “Three top-grade Yellow Spring Roots, each one is a rare find in the world.”

Lu Lingxi carefully observed the three Yellow Spring Roots. The first root was oozing a liquid like tears of blood, the second root became transparent under the candlelight, and the third root had images of vengeful spirits appearing on its surface.

"Are there any differences between these three Yellow Spring Roots?" Lu Lingxi asked.

"The first one is called 'Blood Tears,' formed from the blood and tears of countless wronged souls, and possesses powerful curse power," the black-robed elder said, pointing to the first Yellow Spring Root.

“The second one is called ‘Phantom,’ which can cause hallucinations, making people see their greatest fears,” he said, pointing to the second Yellow Spring Root.

"The third plant is called 'Soul Binding,' which can imprison a person's soul, preventing them from ever being reborn," he said, pointing to the third Yellow Spring Root.

Lu Lingxi frowned slightly. She sensed that something was wrong with the three Yellow Spring Roots. She stretched out her finger, and a ball of bright spiritual energy gathered at her fingertip, shining it on the third Yellow Spring Root.

Instantly, the vengeful image disappeared, replaced by some small engravings, the traces of the soul-binding array.

"This is a Soul-Binding Formation?" Lu Lingxi said coldly. "You actually used a Soul-Binding Formation to forge the Root of the Underworld?"

The old man in black robes was silent for a moment, then said, "Young lady, you have good eyesight, but these three Yellow Spring Roots are indeed real."

"Is that so?" Lu Lingxi smiled. "The blood and tears on the first root are actually the venom of the Ghost-Faced Spider, right? The second one turns transparent in the moonlight, so it's actually grafted with the Western Region Illusion Grass, right? As for the third one, you used the Soul-Binding Array to imprison some wronged souls, letting them attach to the root and disguise it as the Yellow Spring Root. Am I right?"

The old man in black robes trembled slightly. He hadn't expected that Lu Lingxi could see through these disguises. What surprised him even more was that these forgeries actually contained the secret techniques recorded in the Flying Snow Palace's Pill Scripture.

"Are you from the Flying Snow Palace?" the old man in black robes asked.

“No.” Lu Lingxi shook her head. “But I have some knowledge of the alchemy scriptures of the Flying Snow Palace.”

"I see." The old man in black robes nodded. "It seems I've met an expert today."

Suddenly, nine fine, hair-like poison needles flew out from the old man's sleeve and shot towards Lu Lingxi. Zhuque reacted quickly, flicking her tail feathers and spewing out a flame that melted the nine poison needles into molten iron.

"Nine Yin Poison Needles?" Lu Lingxi looked at the molten iron on the ground and sneered, "You really are willing to spend a lot."

"Hmph, I'm just unlucky today," the old man in black robes said. "But you won't have it easy either."

"Really?" Huan Yue suddenly said, "I smell the fishy odor of a swamp venomous dragon on you. You're in cahoots with those guys, aren't you?"

The old man in black robes changed his expression. He hadn't expected Huan Yue's sense of smell to be so sharp. He knew he was doomed today.

"Let's go," Lu Lingxi said, not wanting to waste any more time here.

The four turned and left Jiuyou Pavilion. Just as they walked out of the shop, Lu Lingxi Yao suddenly felt a familiar aura. She looked back and saw a white-clad figure flash by the window on the second floor of Jiuyou Pavilion. The figure was seven parts similar to Nalan Rongzhi.

"That is..." Lu Lingxi was startled. She wanted to chase after him, but found that the figure had already disappeared.

"Master, what's wrong?" Huan Yue asked.

"It's nothing." Lu Lingxi shook her head. "Let's keep going." Although the figure only flashed by, Lu Lingxi was filled with doubt.
