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

The phantom suddenly spoke up, "Master, I might have a way to help you."

"What method?" Lu Lingxi's eyes lit up, and she quickly asked.

“Master, my true form is the Demon Blood Vine!” the phantom said.

“It’s a spiritual plant from the Demon Realm.” Lu Lingxi nodded.

“Yes, although the Demon Blood Vine is a spiritual plant of the Demon Realm, it also has a special ability, which is to absorb and transform various energies, including demonic energy,” Phantom explained. “I can absorb the demonic energy in your body and then transform it into energy that I can use.”

"But didn't you say before that although this demonic energy was a bit troublesome for you, it didn't pose a threat? Why are you saying now that you can use it?" Lu Lingxi asked in confusion.

"That's because the demonic energy I absorbed before was extracted from the remnant soul of the Poisonous Dragon. That demonic energy had already been refined by the Poisonous Dragon, so it was like 'cooked food' to me. I could absorb it directly without it having a significant impact on me," Phantom patiently explained. "But the demonic energy in your body is directly invading from the outside, like 'raw food.' If I absorb it directly, it will put a certain burden on my body. But if I convert this demonic energy into energy that I can use, then it will be different."

"I see." Lu Lingxi Yao suddenly understood. "Then what are you going to do?"

"Master, relax your body and don't resist." As the phantom spoke, several dark green vines surged out of his body again and wrapped around Lu Lingxi Yao's body.

Lu Lingxi closed her eyes, relaxed her body, and let the illusory vines enter her meridians. She felt a cool aura flowing through her meridians. Wherever it passed, the remaining demonic energy was quickly absorbed and transformed into a pure energy that merged into the illusory vines.

As the demonic energy was continuously absorbed, Lu Lingxi felt her body gradually return to normal, and the flow of spiritual energy became smoother.

The phantom's aura grew stronger and stronger, and his vines began to shimmer with an eerie black light, as if they contained boundless power.

"Master, I need your help." The phantom's voice rang in Lu Lingxi Yao's mind.

"How can I help you?" Lu Lingxi asked.

“I need you to guide me with your spiritual power to transform this demonic energy into energy that I can use,” the phantom said. “This process may be a little painful, so please bear with it.”

"Okay, I see."

Lu Lingxi nodded. She began to circulate her spiritual power, guiding the illusory vines through her meridians, transforming the demonic energy into pure energy.

As the phantom had said, the process was indeed somewhat painful. Lu Lingxi felt as if her meridians were being pricked by countless needles, causing unbearable pain. However, she gritted her teeth, endured the pain, and continued to guide the phantom's vines.

Time passed slowly, and fine beads of sweat appeared on Lu Lingxi's forehead, her face turning somewhat pale.

Finally, after a long period of torment, Lu Lingxi felt that the demonic energy in her body had been completely cleared away, and the aura of the phantom had become stronger than ever before.

"Master, thank you." The phantom's voice was full of gratitude. "I have converted all the demonic energy within you into usable energy, and my strength has increased considerably as a result!"

"That's good." Lu Lingxi breathed a long sigh of relief. She felt a sense of ease in her body, as if a heavy burden had been lifted.

“Master, we can set off now,” Phantom said. “I can’t wait to see the ‘magnificence’ of this continent!”

"Mm." Lu Lingxi nodded. She stood up, stretched her body, and felt that she had recovered to her best condition.

"Huan Yue, Zhu Que, how are you?" Lu Lingxi asked.

"I've almost fully recovered," Huan Yue said. His wounds had completely healed, and his aura had become even stronger.

“I’m fine too,” Suzaku said.

“Okay, let’s go then,” Lu Lingxi said.

The four left the dense forest and headed towards a distant city. Along the way, they encountered many strange creatures and plants, all of which exuded an eerie aura, making Lu Lingxi feel uneasy.

"This continent is indeed full of strangeness," Lu Lingxi thought to herself. "We must be careful and not let our guard down."

After several days of travel, they finally arrived near the city, which was called "Youlan City". It was the largest city on this continent and a place where various forces converged.

“Let’s go into the city,” Lu Lingxi said. “Let’s find a place to stay first, and then we can gather information.”

The four entered Youlan City and found that the city was even more prosperous than they had imagined, with people coming and going on the streets.

"The people here don't seem to be affected by that black fog."

Huan Yue said that he discovered that although the people here also cultivated, their spiritual power had not changed, nor had any demonic patterns appeared.

“It seems that the influence of that black mist is limited, and only the area near the swamp will be affected,” Lu Lingxi said. “That’s good, at least we don’t have to worry about the people here turning into monsters.”

"Master, where should we stay?" Suzaku asked.

"Let's find an inn to stay at first," Lu Lingxi said. "Then we'll go and gather information."

The four of them found an inn called "Youlan Inn" to stay at. This inn was the largest in Youlan City and a place where all kinds of news gathered.

"Waiter, bring four superior rooms," Lu Lingxi said to the waiter.

"Alright, please wait a moment, sirs." The waiter greeted them warmly and led the four to four superior rooms on the second floor.

"Master, what do we do next?" Huan Yue asked.

"Let's rest for a bit, then we'll split up," Lu Lingxi said. "Huanyue, go and scout out the situation here and see if anything unusual has happened."
