"If you learn the contents of these books, or copy them down and take them to Qingya Mountain, won't the disciples be able to learn the above refining methods at that time? I can also carry forward the talents of my disciples of Qingya Mountain." Lu Xueyuan thought in his heart, took the book in his hand, looked at the old man who claimed to be a confused old man, and said, "Don't you want me to go to see the city lord of Twilight City? How about we make a deal? As long as you lend me this book, I promise to leave this place obediently, and I will never set foot here even a step without a summons in the future!" Lu Xueyuan said, raised the book in his hand and said loudly.

"Humph!" The confused old man glanced at Lu Xueyuan, pouted nonchalantly and said, "Actually, that's what I said, whether you look for my apprentice or not, it has nothing to do with me!" I just want to see what's so peculiar about you girl. Now I can see it, you! It's a female robber!" After he said this, he turned his back to Lu Xueyuan, his body half-bent.

"Hahahaha!" Lu Xueyuan couldn't help laughing out loud, looking at the appearance of this confused second child, he instantly aroused some interest, and his disgust for him suddenly decreased, put the book in his hand into his sleeve, walked forward quickly, and said with a smile: "You are really discerning, and you describe it appropriately!" I'm here to be a robber, but I can't take your stuff for nothing, I don't keep my promise, I said I'd leave here, I really left." She said as she stepped back, turning around and preparing to walk out of this Purple Cloud Palace. But at this moment, there was a call from behind Lu Xueyuan.

"Miss Lu! I haven't seen you for a long time, why are you leaving when you just came?" That person was none other than the city lord of Twilight Sky City that Lu Xueyuan was looking for this time.

When Lu Xueyuan heard this voice, he immediately stopped and looked back at Twilight Tianxing. I saw that Twilight Tianxing was walking out of the Purple Cloud Palace, with his hands behind his back, and he looked at Lu Xueyuan with a smile on his face. Twilight Tianxing was followed by a man in a white brocade robe, the man was handsome and tall. The man had a smile on his face and his eyes were bright, giving people a very shrewd feeling, and it seemed that he should be a henchman by his side.

"Lord of the Twilight City, what a coincidence." Lu Xueyuan said with a smile.

"Hmm! It's really a coincidence, I haven't seen Miss Lu for a long time last time! I wonder what advice Miss Lu has for coming to my Twilight City this time?" Twilight asked.

"I can't talk about advice, it's just that I've heard about the Twilight City Lord these days, and by the way, let's see if one of my people outside the city can help the Twilight City Lord." Lu Xueyuan said with a smile.

Hearing this, Twilight Tianxing nodded and said, "It turns out that Miss Lu is here to help me this time, but I underestimate you." As he spoke, he beckoned to the man behind him and said, "Gui You, let me introduce you, this is the girl Lu I told you before!" After hearing this, the man stepped forward and respectfully bowed his hand, "Miss Lu Xueyuan, the junior is named Guiyou, and she is the most powerful subordinate of the city lord in Twilight City, and he is also the most trusted person!"

"Oh!" Lu Xueyuan nodded, looked at the right in front of him, and did not speak again.

Twilight Tianxing looked at Lu Xueyuan and then at the confused old man behind him, and said, "Master hasn't appeared in this city like this for a long time, is this time planning to stay for a long time?" After listening to his words, the confused old man snorted disdainfully, did not answer, and then walked out on his own.

"Hahaha, my master has always been such a character, Miss Lu, don't be surprised!" Twilight Tianxing said and looked at the figure of the confused old man walking away, but then moved his gaze back to Lu Xueyuan's body. Before Lu Xueyuan could speak, he spoke, "Miss Lu, I have something here, you will definitely be interested!" As he spoke, he stretched out his hand, and at this time, a vivid picture appeared in the sky above the main hall. Among them was the situation where Lu Xueyuan's master, Bai Duchen, and her senior brothers were treating the plague together.

"How do you know?!" Lu Xueyuan asked in surprise.

Twilight Tianxing smiled and stood beside her and said, "I am the city lord of this city, so naturally there are many magic weapons that can be connected to the outside world, and the thing that Miss Lu is most concerned about is the current situation of her master and brothers? I also did this to reassure Miss Lu and settle down in my city."

"But how can I be safe, my master is still treating the plague, and I don't know what happened?!"

「

I heard that you have been suffering from the plague at the foot of the Green Cliff Mountain for a long time?" There was a trace of doubt and surprise in Twilight Tianxing's words, he had also been plagued by the plague, in order to treat the plague, he ran around looking for medicine, but no matter how he looked for medicine, he never got any useful news, he could only pin his hopes on these big forces, hoping that these major sects could solve the plague, but he didn't expect to see someone today actually take the initiative to clean up the plague, and he was also the master of Qingya Mountain, how could he not surprise him!

"Exactly!" Lu Xueyuan said affirmatively, "This plague is a plague, I think the Lord of Dusk City should know it! We, the disciples of Qingya Mountain, have our brothers and sisters take turns to come down the mountain every month, but we can't cure this plague. Now more than 30,000 people at the foot of the mountain have fallen ill, and some of these people's symptoms are exactly the same as those of the deceased. After Lu Xueyuan finished speaking, he looked at Twilight Tianxing's reflection, and looked at his face without showing the slightest surprise, and couldn't help but nod secretly. It seems that this Twilight Sky Walking is a smart man, not a dull person, and since he knows the existence of the plague, he should know how powerful the plague is.

"It turns out that Miss Lu is talking about this matter." Twilight nodded and said.

Lu Xueyuan looked at Twilight Tianxing and nodded, and continued, "Twilight City Lord, I don't know if you have a way to cure the plague at the foot of our Qingya Mountain?"

Twilight Tianxing looked at Lu Xueyuan's expectant appearance, his heart softened, and he said with a smile, "Since Miss Lu trusts me so much, and we are neighbors, this plague incident was also caused by me today. I can't shirk it, but ......."

"But what?" Lu Xueyuan asked.

Twilight Tianxing smiled and said, "But Miss Lu must not know the danger of this plague!" As he spoke, he looked at the man beside him and said to Lu Xueyuan, "This plague is a rare disease, it attacks at night, and its toxins are extremely violent, even immortals can hardly resist it. Our disciples of Twilight Sky City, although they eat a few Pure Heart Pills every year, they cannot eradicate the spread of the plague, they can only be barely suppressed, and the Pure Heart Pill can only temporarily suppress the plague, but it cannot completely solve the harm of the plague, and finally the plague will spread more and more seriously, and it will eventually swallow the entire Twilight Sky City." Z.br>

Lu Xueyuan frowned when he heard this, he really didn't know such a thing, and he couldn't help but feel a little anxious. Twilight continued, "Moreover, the plague is still a chronic disease, only for a week to a month, and ordinary people will not notice it at all, and when the plague breaks out in a week to two months, even the leaders of the great forces like us have nothing to do." He sighed and shook his head as he spoke.

When Lu Xueyuan heard his words, his heart became even more worried, his disciples might really not be able to support it!

Seeing this, Twilight Tianxing continued, "Miss Lu, don't worry too much, we have already researched a medicine to eliminate the plague, this medicine is called the Antidote Pill. However, the herbs we need are more precious, so we only have three herbs now, and I came with you this time to find these three herbs, I wonder if you can agree?"

When Lu Xueyuan heard this, he immediately nodded and said, "Although the Lord of Twilight City has orders, if he can help everyone solve the threat of this plague, he will not hesitate." Lu Xueyuan looked at him and said seriously.

Twilight Tianxing was very happy to see Lu Xueyuan say this, after all, such a character had great value to them in Twilight City. He nodded and said, "Good! Since Miss Lu is so refreshing, then I will say it directly. There are three ways to eliminate the plague, one is to completely eradicate the source of the plague in the process of elimination, and the second is to water the plague with medicinal water, but I am afraid that it will hurt the disciples and people in the town, so I can only let them eat three antidote pills to temporarily relieve the condition. Another is to use acupuncture, but acupuncture has no effect on the plague, it can only temporarily stop the bleeding, but it cannot eradicate the plague."

After hearing this, Lu Xueyuan nodded, and began to think about the three ways to eliminate the plague in his heart.

"There's one last way." Twilight Tianxing suddenly looked at Lu Xueyuan and said seriously. Lu Xueyuan looked at him, his heart sank, and he knew that he must be the most tricky one.

"This last one

One way to do this is to find the source of the plague!" Twilight said.

Lu Xueyuan was stunned when he heard this, and he couldn't help but feel a sense of loss in his heart, it seems that there is only this last method, but this matter is the result of the evil done by the people of the demon clan from beginning to end, where can I find clues about the demon clan? Lu Xueyuan pondered and meditated, but to no avail.

Seeing Lu Xueyuan's distressed appearance, Twilight Tianxing couldn't help but laugh and said, "Miss Lu, have you thought of it?" Lu Xueyuan nodded, "Well, I did think of it, but I'm not very sure, because I haven't seen the source of these infections, let alone found them."

"Hahahaha!" When Twilight Tianxing heard Lu Xueyuan's words, he immediately laughed out loud, it seemed that he had guessed what Lu Xueyuan was thinking, and then looked at Lu Xueyuan and said, "Miss Lu, it's not that you haven't seen the source of infection, but you don't dare to see it! Am I right?" Twilight Tianxing looked at Lu Xueyuan with a confident expression and said.

"Could it be that he already knows about the demons?" Lu Xueyuan frowned, thinking in his heart.
