No matter the situation, she remained calm and composed throughout, without a trace of impetuosity.

Aside from the first few days when she wasn't quite used to the atmosphere and rules of the Alchemy Pavilion in the Loose Cultivator City and was a little hesitant in her actions, she quickly became proficient after a short period of adjustment.

She could learn everything the Xuan Yan Dan Zu taught her immediately, and not only that, she could also apply what she learned to other situations and develop many different ideas. At first, Yue Yuan could teach her, but before long, he was completely unable to handle her questions and had to seek help from the Xuan Yan Dan Zu.

Not only in terms of pill formulas, her mastery of the Golden Crow Fire also improved dramatically under intense training.

Xuan Yan Danzu couldn't stop smiling.

Not everyone can remain immersed in the monotonous alchemy room and weapon crafting amidst the rich and prosperous backdrop of the Loose Cultivator City for ten years, almost never stepping outside!

There are ascetics, but most ascetics live in cold rooms or remote mountains. Given the equally harsh and austere conditions in the outside world, it is only natural that they are strict with themselves.

But Tongsu is different.

The city of rogue cultivators was bustling with activity, and the alchemy pavilion and weapon-refining workshop were noisy every day, yet she remained oblivious to it all.

Surrounded by splendor and extravagance, yet with eyes only fixed on the bright golden crow fire three feet in front of him, he would never glance outwards. It is easy to be influenced by one's surroundings, but to remain pure white even when surrounded by darkness requires immense self-control.

The disciples of the Alchemy Pavilion and the Weapon Forging Workshop were unaware of this, and they were even less capable of doing so.

Those who initially doubted her were completely convinced, impressed, and amazed after seeing her hard work and progress.

“She is really strong,” Yue Yuan said with genuine admiration when talking to others. “Even without the Golden Crow Fire, with her comprehension, perseverance and hard work, she would definitely go further than me.”

Tong Su was unaware of what others thought of her, and she didn't care.

Tian Xuanzi left after spending three months with her. At that time, a conflict arose between the righteous and demonic realms, and he had to rush back to the demonic realm. Not long after, the gate between the realms was completely closed once again.

Tong Su made a special promise to him through the communication mirror, forbidding him from neglecting his duties. Tian Xuanzi was reluctant, but he was genuinely busy. He bargained with Tong Su and agreed that he would definitely come to find him when the gate to the next realm opened. He stayed in the Demon Realm against his will.

Before he returned, Tong Su obtained all the Thunder Vine Fruits from Xuan Yan Dan Zu and helped Tian Xuan Zi recover from his injuries. After returning to the Demon Realm, he should be fully recovered.

Now, fifteen years have passed in the blink of an eye.

Fifteen years is truly a fleeting moment in the eyes of those in the cultivation world, not even as long as a single period of seclusion.

On this day, auspicious clouds gathered in the sky above the weapon-refining workshop early in the morning. Many passing weapon cultivators looked up and their faces lit up with joy: "Which fellow Daoist has advanced to the mid-stage of the Golden Core realm?"

"Judging from the auspicious and fiery aura, could it be Fellow Daoist Bai Tong?"

"Judging by the time, she did indeed go into seclusion a year ago. Could she have successfully advanced? Wow, how old is she!"

The onlookers were astonished. After a quick calculation, their eyes widened in amazement: "When Fairy Bai Tong came to the Loose Cultivator City, wasn't she not even twenty years old? At this rate, she definitely won't be two hundred years old when she advances to the Nascent Soul stage!"

They were discussing things by the roadside and didn't notice that an ordinary-looking male cultivator was walking by. Hearing their voices, he looked surprised and stopped in his tracks.

Bai Tong?

...How come this name is the same as that of Jingyang Immortal Lord's junior sister, who disappeared from the sect fifteen years ago?

—No, that demon is no longer Jingyang Immortal Lord, and Bai Tong is a mentally ill idiot. How could she possibly be the fairy that everyone is talking about!
