Su Yunfei gave Master Zhang some elixirs to prolong his life, and left his house under the reluctant gaze of Master Zhang.

At this moment, Su Yunfei frowned, falling into deep thought, his first thought was the conspiracy of the demon clan, and soon denied this speculation, the human race is extremely strict against the demon clan's world,

As long as the demon clan has any small moves, the human race will notice it as soon as possible.

"Could it be a demon? It's impossible, Alan Temple was built in the western frontier of the human race to prevent the demon race, who the hell is it!" Su Yunfei thought in his heart, he couldn't think of a very good hand behind the scenes, and it was very uncomfortable.

Xiao Yue'er has also been frowning with Su Yunfei these days, she has no concept of these conspiracies, and when she saw Su Yunfei frowning, she also learned.

Su Yunfei is closer to her heart than her own brother, and many times she deliberately imitates Su Yunfei, for example, Su Yunfei kidnapped many geniuses of the sect before, and she also wanted to kidnap one or two.

Xiao Yue'er's frowning appearance made Su Yunfei laugh, he rubbed Xiao Yue'er's brows, hugged her affectionately, and said softly:

"Don't frown every day, be happy, you know? Originally, Brother Yunfei wanted to take you out to play, but I didn't expect to encounter such a thing, next time my brother will definitely take you out to play!"

Xiao Yue'er nodded her little head heavily, mumbled, hugged Su Yunfei's neck, smiled, and said:

"Brother Yunfei, as long as Xiao Yue'er can be with her brother, she will be happy no matter what she does!"

Toot toot!

Su Yunfei's sound transmission stone rang, he hurriedly put down Xiao Yue'er, took out the sound transmission stone, and heard Liu Rusheng's voice,

"Brother, how are you doing over there?"

Su Yunfei told him what he learned from Master Zhang.

The situation on Liu Rusheng's side is about the same as on his side, and there are still no valuable clues.

The two sides were silent for a moment, and Su Yunfei said:

"Let's go to the capital now and ask Master Li Kangda!"

Immediately, Su Yunfei flew to the capital with Xiao Yue'er's sword, and joined Liu Rusheng and Cai'er on the way, and it was already late at night when he arrived in the capital.

Li Kangda received Su Yunfei's message in advance and was already waiting in the Li Mansion.

"Immortal Master Su, we haven't seen each other for more than two years, although we haven't seen you in the past two years, I can hear your legend every day!"

After seeing Su Yunfei and the four of them, Li Kangda was excited, he and Su Yunfei were old friends, and they admired each other very much, a young sword cultivator who moved the world, and a prime minister who leaned towards the government and the opposition.

When he arrived at the lobby of the Li Mansion, Li Kangda retreated left and right, Su Yunfei explained his intention, Li Kangda was instantly emotional, and said:

"Back then, I felt that the plague was wrong, and I suspected that someone was playing a ghost, if you think about it, there is a plague that is specifically aimed at young people, and it is also a young person with special abilities, with a 100% fatality rate, and those officials who participated in the management of the plague, all died within three years, it is too strange, but my ability was limited back then, and I was also soft-spoken, and I didn't find out anything, and no officials supported me to investigate."

After speaking, Li Kangda sat on the Taishi's chair and was heartbroken, as a good official who loves the country and the people, how could he not be sad to see such a young man die.

Su Yunfei and the others were also silent for a while, the atmosphere was a little sad, and after a while, Su Yunfei asked:

"Master Li, did you find any clues back then?"

Li Kangda pondered for a moment, suddenly his eyes lit up, and said:

"I remember, every place where there is a plague, there have been monks passing by, those monks will stay for a month, and within a few days after the monks leave, there will definitely be a plague in this city, because many monks will go down the mountain to practice, and it is normal to pass by some cities, so this suspicion cannot be regarded as a suspicion, but I think it is too boring, too coincidental."

After listening, Su Yunfei was not too excited, he also found out this suspicion, it is true that there are often monks passing by or living in every city, which is normal.

Suddenly, he slapped his chair and said eagerly:

"Just now I thought back to the plague in Great Xia over the years, the one thirteen years ago

Is the plague the biggest and worst ever?"

Li Kangda, Liu Rusheng recalled for a moment and nodded.

"Does it feel like some kind of finish, the real culprit behind the scenes is either to complete the task and finish, or to encounter something that threatens his life and death, and has to be closed, I tend to the second one."

"How so?" Li Kangda, Liu Rusheng and Cai'er hurriedly asked.

"To be able to carry out such a big conspiracy, there is definitely the support of a big sect behind it, although I don't know what use they have for these innocent people, but it must be of great benefit to the sect, and the benefits must continue, and what they have done is so airtight that it is almost impossible to find, and they have ended, they must have encountered an unstoppable crisis, so as long as you find out which major sect was destroyed or disappeared thirteen years ago, there will be clues!"

Su Yunfei turned into a detective and told the story, Li Kangda, Cai'er, and Liu Rusheng were excited, and Xiao Yue'er clapped her little hands to cheer for her Yunfei brother.

Immediately, Su Yunfei took out the sound transmission stone, and two quarters of an hour later, the voice of the disciple on duty in the Shushan Sword Shrine Classics Room sounded in the sound transmission stone, and there were only three words:

Demon Martial Sect!

Su Yunfei was a little familiar with this sect, and suddenly he thought that Shangguan Yun, the beloved disciple of Situ Yan, the president of Bailu Academy, was in love with the holy daughter of the Demon Martial Sect, and was stopped by Situ Yan, Shangguan Yun was carried away by love, left Bailu Academy, and was surrounded and killed by the people of the Dragon Hunting Mercenary Group, and finally the corpse was taken away by the head of the corpse chasing faction and refined into a divine corpse.

The Demon Martial Sect was originally called the Martial Sect, and its status was the same as that of the Sword Sect, and it was the first martial arts sect of the Terran race, and it was suddenly changed to the Demon Martial Sect by the Sect Master of the Martial Sect 10,000 years ago, and it also became a famous demon sect of the Terran race.

The so-called Demon Sect is not the kind of sect that kills people without blinking an eye and does all the bad things, but acts more casually and does not follow the inherent values and morals, so it is resisted by all the famous and decent families of the human race.

However, although the Demon Martial Sect is a demon sect, it has never done anything that angers the heavens and people, so there is no crusade against the sect, at most the two sides have a little more verbal fighting.

"Could it be that the Demon Martial Sect did it? Judging from the strength of the sect, it does have this ability!" Su Yunfei pondered.

Soon, the disciple on duty in the Shushan Sword Shrine Classics Room sent another transmission,

The Demon Martial Sect suddenly disappeared thirteen years ago, and even the sect disappeared with it, and the human race has not found any disciples of the Demon Martial Sect so far.

"The plague must be inseparable from the Demon Martial Sect, after the Martial Sect changed to the Demon Martial Sect ten thousand years ago, the plagues of the human race were more frequent than before, and the one thirteen years ago was obviously the end." Liu Ru said angrily.

Su Yunfei waved his hand, signaling Liu Rusheng to calm down, he thought that the sudden disappearance of the Demon Martial Sect was probably done by Situ Yan, if it wasn't for the Demon Sect Holy Maiden, how could Shangguan Yun die unexpectedly.

With the strength of the White Deer Academy, there is no problem at all in quietly destroying a large sect and erasing all traces.

Su Yunfei decided to go to the White Deer Academy to ask Situ Yan, if it was really the Demon Martial Sect destroyed by the White Deer Academy, then those people who got the plague would be hidden in the end, or where their use value was, there would be an answer.

With the clues, everyone relaxed a lot, and had a big drink in the Li Mansion, and the next day as soon as it was dawn, Su Yunfei and the four of them set off for Bailu Academy.

Because I came in a hurry this time, I really didn't have much mood, so I didn't go to see Emperor Daxia, Princess Anping and Qin Chuan.

At noon, the four of them came to the White Deer Academy, Xiao Yue'er, Cai'er, and Liu Rusheng came to the legendary White Deer Academy for the first time, and they were all very curious.

Especially Liu Rusheng, before he became a monk, he was a scholar, and he longed for Bailu Academy, at this moment, he couldn't help but tie up his long hair and tidy up his clothes.

The temperament of the whole person has changed from wild and uninhibited to gentle and elegant, and those who don't know will really regard him as a scholar of Bailu Academy.

The four of them walked very slowly, Su Yunfei was to take care of the curiosity of the three of them, and the three of them wanted to take a more look at Bailu Academy.

After a leisurely tour, the four of them finally arrived at Situ Yan's courtyard.

For the arrival of the four people, Situ Yan had already sensed it, and he had already prepared spiritual tea at this moment.

At the stone table in the courtyard, waiting for Su Yunfei and the four of them.

Shangguan Yun didn't listen to anything outside the window, and only read the sage books, his memory recovered a little, and he wanted to make up for the cultivation that had fallen over the years.

"Meet Dean Szeto!"

Su Yunfei bowed and said respectfully.

Situ Yan waved his hand and said with a smile:

"No need to be polite, just sit down!"

The four of them sat straight, like students listening to Mr. 's teachings, not intentionally, but in the face of Situ Yan, they would subconsciously be very restrained.

"You must have something to ask for, don't be restrained, just say it." Situ Yan said with a smile.

Su Yunfei explained the intention, when he heard the three words of the Demon Martial Sect, Situ Yan's face turned cold, and an uncontrollable momentum suddenly erupted, if he hadn't put away this momentum in time, Su Yunfei and the four of them would have either died or been injured, which shows how much he hated the Demon Martial Sect.

Shangguan Yun, who was reading in the grass hut, instantly stopped reading when he heard the Demon Martial Sect, feeling familiar but unable to remember, Situ Yan saw this, and waved his hand, isolating the sound in the courtyard.

Situ Yan said in a deep voice:

"When my apprentice disappeared, I did suspect the Demon Martial Sect for the first time, I checked it, it was not the Demon Martial Sect that did it, and I did think about destroying the Demon Martial Sect, but after all, it was a matter of love between men and women, and this reason was not enough for me to say that the Academy destroyed the Demon Martial Sect, and finally the Demon Martial Sect suddenly disappeared, and I also checked for a while, but I didn't find a trace of it."

After Su Yunfei heard this, his heart was cold, and the clue was broken again.

Just when the four of them were depressed, Situ Yan seemed to remember something and said:

"By the way, when I went to Fahua Temple to debate with the abbot before, I happened to learn that at the beginning of the plague in the thirteenth year, a monk from Fahua Temple passed by a village that was plagued, and the monk recited a sutra of suppression, and as a result, those who had the plague miraculously recovered, and the monk should still be in Fahua Temple, you can go and ask."

Su Yunfei and the four of them were excited, and after bowing deeply to Situ Yan, they eagerly walked out of Bailu Academy and flew to Fahua Temple.
