The rag picking sister turned out to be a weapon refiner

As Tan Yuruo put down her hand, the air wall in front of them condensed into a staircase leading directly upwards. The staircase looked a little broken, vaguely visible and incomplete. After looking at each other, the few of them decided to go up and see what was going on.

Going up all the way, at the end of the stairs, an ancient door stands quietly, with intricate totems carved on it, emitting a faint spiritual light.

Hu Xingtong gently pushed open the door, and a stronger burst of ancient atmosphere came to his face, accompanied by a faint smell of mold. It was obvious that no one had been here for a long time.

The four of them entered the second floor, only to find it completely different from the first. It was more spacious, with a massive stone table in the center, scattered with several yellowed ancient scrolls. Surrounding it were circles of bookshelves, but the bookshelves were noticeably fewer than on the first floor, and each one exuded a richer aura.

"This place... seems more like a library than the place just now!" Sinan whispered, his eyes scanning the surroundings, trying to find useful skills.

Hu Xingtong activated her Scanning Eye once again, her gaze piercing through the bookshelf, searching for clues while also searching for a technique that suited her. However, this time, the Scanning Eye seemed to be restricted in some way, unable to penetrate the pages as freely as before.

"It seems something is unusual here." Hu Xingtong thought to herself. She turned to look at the three people and said, "Let's act separately, but stay vigilant. If we find anything unusual, notify the others immediately."

The three nodded in agreement, and the four of them split into two groups again and began their respective explorations.

Hu Xingtong walked alone towards the seemingly ordinary bookshelves. Her eyes swept across the bookshelves. These books recorded the methods of cultivating the soul. She was quite interested in them. After all, she had no method to cultivate the soul before, so she had no choice but to attack her own body and almost died.

Suddenly, a book with no words on its cover caught her attention. She reached out and took it down, only to see that the cover exuded a faint ancient aura, as if it contained some kind of sealing formation.

Hu Xingtong carefully opened the book and saw that the pages were densely packed with various mysterious runes and patterns. The power formed by these runes and patterns connected together was something Hu Xingtong had never heard of before.

At this moment, Chen Wu's voice rang out again in Hu Xingtong's mind: "Xingxing, be careful. The book in your hand is set up with a formation. It requires special means to read."

Hu Xingtong was startled and quickly closed the book, looking around cautiously. He patted his chest to comfort himself, thinking that he hadn't finished reading yet. Why were there any formations in the books here? Could there be some hidden secrets?

Just then, a burst of hurried footsteps came from the stairs. Hu Xingtong's heart tightened. He quickly hid the book in his arms and turned to look at the stairs.

Tan Yuruo, Gu Sihe and Sinan hurriedly ran up, their faces full of tension and anxiety.

"What's wrong? What happened?" Hu Xingtong asked hurriedly.

"We...we found a secret room." Tan Yuruo said breathlessly, "but the entrance to the secret room is blocked by a powerful ban, and we can't open it."

Hu Xingtong's heart skipped a beat when he heard this. A secret room? This could very well be the key to unlocking the secrets of the Heavenly Soul Sect.

"Come on, take me to see it." Hu Xingtong said, and walked towards the stairs first.

When the four of them arrived at the entrance of the secret room, they saw a ban flashing with lightning that tightly blocked the secret room. The aura emanating from the ban made the four of them terrified.

"This... this restriction is too powerful, we can't open it at all." Gu Sihe said somewhat desperately.

Hu Xingtong stared at the restriction with a serious look, constantly pondering a countermeasure in her mind. At this moment, she suddenly remembered the book in her arms.

"Perhaps, this book can help us open the ban." Hu Xingtong said, then took the book out of his arms and opened it carefully.

As the pages turned, a mysterious force surged from the book, charging towards the restriction. The four people only saw the lightning flash on the restriction a few times, then gradually dissipated, and finally turned invisible.

"Success!" Hu Xingtong exclaimed excitedly. She quickly closed the book, put it in her arms, and then took the lead to walk towards the entrance of the secret room.

At the same time, Hu Xingtong was thinking in his heart that using books to hide the secret key of the formation is a good method. If he made one himself, he could set up a trap for others at any time in the future, and only he could remove it. Isn't this the same as the combination lock in the real world?

As they walked through the corridor of the secret room, Tan Yuruo and Sinan simultaneously noticed the glow emanating from Hu Xingtong's chest. Tan Yuruo asked, "Senior Sister, the book on your chest is glowing."

Hu Xingtong looked intently at the book and saw that the patterns on it were indeed emitting light. Thinking that Tan Yuruo was also a talisman master and might be able to discern some clues, he handed the book over and asked, "There are some patterns on it. I felt it was a little dangerous, so I put it in my pocket. Take a look at these patterns. Do you recognize them?"

Tan Yuruo took the book and was shocked by the patterns in it at first sight. It was not that she discovered the running trajectory, but she was shocked by the technique of drawing the patterns. She looked at Hu Xingtong, wanting to speak but hesitant, but she didn't know how to start while considering.

"What do you want to say?" Hu Xingtong was annoyed by the question of whether to say it or not, so he asked directly.

"Well... Senior Sister, do you want to change your clothes? The pictures and texts on them are drawn with dragon yellow..." Tan Yuruo rubbed her nose in embarrassment, not daring to look at Hu Xingtong.

"Dragon yellow? Is it dragon's... feces?" Hu Xingtong was also a little confused, but after he came to his senses, he decided to confirm it.

Not daring to respond, Tan Yuruo could only nod slightly. Now, Hu Xingtong felt very bad. He took out a barrier array plate from the storage ring and threw it out. In an instant, he disappeared in front of the three people. When he reappeared, he had changed into a green robe with a gloomy face.

"Which good person would use this to draw talismans? Don't you mind the smell?" Hu Xingtong burned the clothes he had taken off in disgust, and then walked straight forward without even looking at the book.

This reaction was very funny to the three of them. They couldn't help laughing and followed him. With the help of the book, they had a smooth journey and walked into the center of the secret room.

"I always feel that we are so lucky. We have found many places that our predecessors have not been able to find." Hu Xingtong sighed, and the three people beside him also echoed him.

But there was inevitably some worry in the echoing voices. Gu Sihe looked at the few people and asked worriedly: "Do you think there will be danger? After all, my sister told me that there is no free lunch in the world. We can find places that so many seniors have not found. Will something bad happen?"

Hu Xingtong listened and thought to himself, you are absolutely right. This system of mine let me in for a purpose, otherwise how could I complete the hidden mission.
