In the Sutra Library, Qiu Changtian found the book "Mirror Flowers, Water Moon".

He returned to his seat, laid the book flat with Junior Sister Xu, and then opened it carefully.

I saw that the pages of the book were slightly yellowed and the ink was old and dim, as if it had been there for quite a long time.

Xu Yinglian flipped through the book from beginning to end, read it quickly, and then shook his head in confusion:

"No problem. Are you sure this is the book that Junior Brother Qiu borrowed?"

"In the Sutra Repository, there are no extra copies of any of the books, and there is only this one copy of Mirror Flowers, Water Moon." Qiu Changtian replied.

He pulled the book in front of him and called out:

"Ajing, scan!"

After waiting for a long time, Kunlun Jing said hesitantly:

"strangeness……"

"What's strange?"

"There is a thread of space in here." Kunlun Mirror replied.

"Space thread?" Qiu Changtian pondered for a moment and scolded it, "A Jing, speak human language, and don't speak mirror language."

"For example, if there are two independent spaces that are not connected to each other." Kunlun Jing did not get angry with him, but just explained, "Then the creatures in one space will definitely not be able to enter the other space."

"However, in most cases, two adjacent spaces often have a lot of adhesion. For example, secret realms often have entrances and exits. These passages that grow out from the edge of the space and adhere to other spaces are called 'thread ends', just like the thread ends that sew different fabrics together on clothes."

"So what you're saying is..."

"I guess your junior brother Qiu must have accidentally touched the thread of space through some means." Kunlun Jing said thoughtfully.

"And then you traveled through time?" Qiu Changtian asked in surprise.

"That's about it, that's what it means." Kunlun Mirror replied, "I was pulled by the thread and traveled to the opposite space."

"What's the space across from you?"

"I don't know, it's a very large cave."

Qiu Changtian thought for a moment, then turned to Xu Yinglian and said:

"There is a hole in this book."

"How did you know?" Xu Yinglian asked in disbelief, eyes wide open.

"Let's not talk about this for now." Qiu Changtian asked with a smile, "Junior sister, should we go in?"

“Don’t forget, Junior Brother Qiu is a disciple of the Huafu Stage. The cave that allowed him to explore alone without telling anyone is likely to contain the Purple Palace Secret Medicine.”

"Indeed." Xu Yinglian was immediately tempted, "But how do we get in?"

"Let me check it again." Qiu Changtian said calmly and confidently, then turned around and asked Kunlun Mirror:

"A Jing, how do we get to that cave?"

"Oh, it's very simple." Kunlun Jing said casually, "I'll do it."

As soon as the words fell, the two felt the world spinning around them, and then they appeared in a strange world.

I saw what seemed to be an island below, surrounded by endless ocean.

Above the two of them were layers of dark clouds. Although they looked like calamity clouds, they did not have the solemn and murderous atmosphere that permeated the sky and earth. They seemed to be just ordinary cumulonimbus clouds.

Qiu Changtian and Xu Yinglian looked at each other, then quickly landed towards the island below.

There is a fairly large town in the middle of the island, with houses lined up in rows. It is roughly estimated that there are about a thousand households.

At this time, the residents were gathering in an open space in the center of the town, shouting at the mayor in indignation.

Dozens of armed guards holding spears were seen murderously dispersing the residents and forcing them back to their respective homes.

Qiu Changtian and Xu Yinglian lowered their swords and landed in the center of the town. The guards around them immediately looked as if they were facing a formidable enemy and rushed over with spears in hand.

"Wait, stop it!" The mayor hurriedly called the guards to stop, then walked forward cautiously, bowed and said, "Greetings to the two immortals."

"No need to be polite." Qiu Changtian said gently, "Let me ask you, have you ever seen such a cultivator?"

He briefly described Junior Brother Qiu's appearance and clothing, and the mayor immediately nodded and said:

"I have seen it! I have seen it! The immortal said he would help us solve the problem of lightning strikes. After taking the lightning-proof pill, he rushed directly into the thundercloud."

"Struck by lightning?" Xu Yinglian asked in surprise.

"It's not safe here." The mayor stared at the cumulonimbus clouds above his head and said with a fearful look, "Please follow me, both of you. I will explain later."

He ordered the soldiers to return to their respective guard posts, then took the two men home, closed the door, and called his wife to pour tea for them.

"Let the two immortals know." The mayor said with a bitter face, "Two immortals, you should have seen the thunderclouds above our heads, right?"

"Not bad." Qiu Changtian nodded slightly.

"Our town is called 'Thunder Town'. According to the records left in the town, the thunderclouds above are called 'evil spirit disaster clouds', which are the evil spirits gathered after a person dies." The mayor sighed and said, "About every hundred years or so, they will descend over the island."

"When the evil cloud descends, everyone must stay at home and not be outdoors, otherwise there is a certain chance that they will be struck to death by lightning."

"This is strange." Qiu Changtian pondered.

He was a practitioner of the Five Thunders Law, so he naturally knew that calamity clouds of thunder and lightning like these were usually created to target a certain target, and that specific target would be struck.

This was the first time he had heard of thunderclouds that indiscriminately and randomly killed people on a large scale, as the mayor had described... But considering that it was condensed evil spirits, perhaps it was essentially an intelligent demon.

"If that's the case, why did those residents gather outside just now?" Xu Yinglian asked puzzledly.

"Alas." The mayor said dejectedly, "Once the evil clouds arrive, they will stay over the island for a period of time, but the length of time is unknown. It could be as short as a few days or as long as more than ten days."

"At first, the calamity cloud is not active, but if the lightning strikes and kills someone, the calamity cloud will grow stronger and stay longer accordingly."

“If thirty or forty people die, the calamity cloud will cover the entire island, making the day as dark as night, and it will stay for at least half a year. By then, every household will be destroyed!”

“So I followed the instructions of my ancestors and ordered the residents to stay at home and not go out until the robbery cloud leaves. However…”

"Oh." Xu Yinglian was also a smart man and understood immediately, "There are also differences between the rich and the poor among the residents. If they are not allowed to go out to farm and fish, the rich may be able to survive for ten days, but the poor will run out of food in a few days."

"That's right." The mayor sighed, "I have already talked to the wealthy families, hoping to get some food to help the poor."

Qiu Changtian and Xu Yinglian looked at each other for a moment and sighed in their hearts.

It is difficult for people to understand each other's joys and sorrows. In times of natural disasters, it is good enough that the rich do not sell grain at high prices, but they also provide relief for free?

"Luckily, at this time, the immortal you two were looking for suddenly appeared and said he wanted to remove the evil calamity cloud in the sky for the town." The mayor said carefully, "I followed the instructions of my ancestors and gave him one of the lightning-proof pills left by them. The immortal then turned into a sword light and rushed into the calamity cloud to cast a spell."

"And then?" Xu Yinglian continued to ask.

"And then...there was no news of that immortal anymore." The mayor said with a sad face.

Although his demeanor was quite natural, Xu Yinglian was a very perceptive person after all, and he keenly sensed the slightest bit of unnaturalness in it. He immediately glared at him and angrily said:

"What are you hiding? Why don't you just tell the truth!!!"

The mayor was so frightened that he immediately knelt down and cried:

"It has nothing to do with me! Please look carefully, Immortal. I have warned you many times, but there are still six or seven unruly people in this town. After you rushed into the evil cloud, they still ignored the ban and secretly went out to sea!"

"Later, the calamity cloud killed one of them, and the remaining five or six fled back to the town in a panic. I immediately realized that something was wrong, and found that the calamity cloud in the sky had grown much larger, and the sword light in the cloud had gradually lost its strength, and finally dimmed... I think the immortal was harmed by the calamity cloud, but it was not me who secretly harmed him. I just couldn't do anything about it!"

The mayor was crying and sobbing as he spoke bitterly.

Qiu Changtian and Xu Yinglian exchanged glances again, and their expressions became a little complicated.

This Junior Brother Qiu...how should I put it, he is really unlucky.

At the critical moment of the battle with Jieyun, it happened that some residents of the town went out to sea without permission and were killed by lightning, which made Jieyun even stronger.

This was the straw that broke the camel's back, leading to his unfortunate downfall and death.
