Now I’ll translate and polish the text according to the guidelines provided:

TRANSLATION:

Yang Lian’Er wore an expression that screamed "are you kidding me?" as she said, "How is that possible?"

Aunt Fan sighed, "I also thought it was impossible, but it happened anyway."

Yang Lian’Er’s eyes gradually widened. "So this guy really had a breakthrough?"

"Yes! Haven’t you noticed he’s grown much taller?"

"You’re right!" Yang Lian’Er carefully thought back and realized Wu Liangchen was indeed taller than before.

"That’s one of the signs when mastering tendon and bone transformation."

Yang Lian’Er was dumbfounded. "But this is too..."

"Too shocking and unprecedented, right? I felt the same way when I first noticed. I never imagined the little carriage driver you picked up on a whim would possess such extraordinary talent," Aunt Fan couldn’t help but marvel.

As the two were talking in the room, a sudden loud boom came from outside.

Aunt Fan immediately rushed to the courtyard and with a single leap, bounded onto the roof to gaze toward the source of the sound.

Yang Lian’Er soon joined her side and said softly, "It’s coming from North City!"

"Yes, they must have started their operation!" Aunt Fan said.

Although they couldn’t see clearly due to the distance, the faint battle cries revealed everything.

"I wonder how many people will survive this disaster," Yang Lian’Er sighed softly, her gorgeous face bearing a trace of compassion.

Hearing this, Aunt Fan remained silent for a moment before finally saying quietly, "Let’s go back inside, miss."

-----------------

With such a commotion, Wu Liangchen naturally heard it too.

His sister Wu Mengchan asked nervously, "Brother, what’s happening outside?"

"Don’t worry, it’s probably refugees entering the city. As long as we stay home and don’t go out, nothing bad will happen to us," Liangchen reassured her.

Mengchan nodded and went to the inner room to do her needlework.

No matter how chaotic the outside world became, she feared nothing as long as her brother was by her side.

Wu Liangchen had no intention of rashly venturing out into that mess.

Whether it was the Heartless Dao or the Great Yan authorities, neither had anything to do with him.

His only concern was his sister, followed by the people close to him.

As for others, he regretfully lacked the ability to help them.

While he was at home quietly consolidating his martial Cultivation and taking stock of his recent gains, Liu Dongchuan arrived.

As soon as he entered, Liu said in a nervous yet excited tone, "The Canal Gang at the docks has made their move. At least two Hall Masters showed up. Besides them, those Martial Artist masters in North City couldn’t sit still either and began taking action, but even so, they’re still losing ground."

"These refugees are terrifyingly strange—every one of them fights without fear of death. Even when seriously wounded, they keep charging forward. They’ve already captured several streets."

"How did you learn all this?" Wu Liangchen asked curiously.

"Hehe, I may be just a minor leader at the docks, but I still have a few reliable brothers under me. They’re the ones who told me all this," Dongchuan said rather proudly.

Wu Liangchen fell into deep thought.

It sounded like the Heartless Dao was winning decisively, perhaps even on the verge of completely taking over North City.

But Liangchen understood things couldn’t be that simple.

After all, North City was home to powerful family clans and various martial arts schools, and they likely hadn’t used their full strength yet. 𝑓𝘳𝘦𝑒𝑤𝑒𝘣𝘯ℴ𝘷𝘦𝓁.𝑐𝑜𝑚

Soon enough, however, Liangchen dismissed these thoughts.

It didn’t matter to him who won or lost, and he couldn’t be bothered to waste mental energy on it.

"Brother Liu, be careful these days and try to stay off the streets."

"I understand!"

After chatting a while longer, Liu Dongchuan left.

By then it was nearly dark. Mengchan had prepared dinner early, and the siblings sat around the table, eating and talking.

"Brother, do you still have to go out tonight?"

"Yes, I need to serve night duty for my employer. But don’t worry, I’ve already spoken with Brother Liu and his people. They’ll look after you. If you’re really afraid, I can ask Sister Liu to come keep you company," Liangchen said.

"I’m not afraid. I just... brother, please be careful," Mengchan said worriedly.

Wu Liangchen looked up and smiled at his sister. "Don’t worry, I know what I’m doing."

After dinner, having gathered his necessities, Wu Liangchen locked the doors and windows securely before leaving the compound and heading toward Yang Lian’Er’s residence.

Along the way, the streets were completely deserted—not a single person, not even a stray cat or dog.

A pale moon hung in the sky as the early winter wind whistled through the treetops, creating a mournful sound that felt extremely desolate.

Wu Liangchen sighed quietly and was about to turn into an alley when a flash of fire lit up the horizon.

He whipped his head around, a fierce glint flashing in his eyes.

The fire had started at the border between North and South City, not far from where he stood.

With no rain having fallen since Mid-Autumn Festival, everything was bone dry, and within moments, the flames were shooting skyward.

"Damn these bastards!" Wu Liangchen realized he had overestimated the moral baseline of this world.

Regardless of which faction had started the fire, their intentions were extremely sinister.

This was because most buildings in Dinghai City were wooden structures, and once the fire spread, it would be no ordinary disaster.

Wu Liangchen abandoned his plan to visit Yang Lian’Er. He quickly ducked into an alley, changed into his night clothes, put on a face mask, and with a single leap bounded onto the roof ridge, rushing toward the source of the fire.

Moments later, Wu Liangchen stood on a collapsed section of the city wall, his gaze dark as he watched the distant fire.

The blaze was ferocious, having already consumed several streets in the blink of an eye.

Most of these streets belonged to South City, with only a small portion in North City.

Moreover, with his sharp vision, Wu Liangchen could see that the streets engulfed in flames were littered with corpses.

Under the scorching fire, the air was filled with the stench of burning clothes and the sickening smell of roasting flesh.

In front of this hellish scene, a group of people were still fighting.

On one side were disciples from the wealthy families and martial arts schools, while on the other were people dressed in uniform white clothes with lotus-patterned scarves covering their faces.

The two sides were locked in brutal combat.

At the same time, refugees swarmed toward North City like locusts.

The street patrols who normally bullied the common folk were nowhere to be seen, but these refugees didn’t enter uncontested territory.

To protect their businesses, shop owners along the streets had united to block the refugees’ advance.

Among them were several Martial Artists.

But it was all useless.

These refugees seemed like demons crawling out of hell, each fighting without fear of death.

Wu Liangchen witnessed a Martial Artist slice off a refugee’s arm with his sword.

Such a severe injury would be unbearable for any normal person.

Yet this refugee showed no sign of pain, howling as he charged forward and bit into the Martial Artist’s chest.

The Martial Artist cried out in pain and severed the refugee’s head with his sword, but even then, the head didn’t release its bite, remaining attached to the Martial Artist’s chest.
