Step 2: Integrated Translation and Polishing

Now I’ll proceed with the translation while applying all the required rules:

The text begins with a nighttime setting in Dinghai City, with Wu Liangchen having just broken through to the Second Realm of martial arts and testing his new abilities by running across the city. He encounters a suspicious person in dark clothes who appears to be heading toward the South City area. Wu Liangchen follows this person and discovers they are trying to drug someone in the Bai family’s home (likely the daughter). Wu Liangchen intervenes, scaring off the attacker and then chases after them.

Let me translate the full text while keeping all the rules in mind:

Tonight, there was no moon!

Ink-black darkness blanketed all of Dinghai City. This bustling city, noisy throughout the day, had finally fallen silent.

A flock of black crows perched on the long-abandoned clock tower, their glossy eyes staring down at the city below, as if waiting for new prey to appear.

In today’s Dinghai City, only these carrion-eating crows could still survive.

Nearly all other birds and beasts had been eaten by the starving refugees.

The crows waited patiently. As soon as a refugee collapsed, they would swarm down to peck at their eyes, tongues, and any other edible parts.

At first, people had tried to drive them away, but as the disaster grew more severe, they simply gave up and let them be.

Because of this, once night fell, these black crows could be seen everywhere on Dinghai City’s walls and trees.

As the night deepened, the distant sound of a watchman’s gong echoed.

"DONG! DONG DONG!"

"Fourth watch of the night! All is well!"

Just then, a dark figure cut through the thick darkness, moving at incredible speed across the top of the city tower.

The crows were startled by this intrusion, and as several took flight, the shadow lightly stepped on one of them.

BOOM!

The tremendous force instantly turned the crow into a mist of blood. The dark figure used the momentum to propel himself upward again, quickly disappearing above the tower.

Moments later, Wu Liangchen finally stopped, landing on a section of the city wall that had already half-collapsed. He let out a long breath, feeling an unprecedented sense of exhilaration throughout his body.

Just half an hour ago, he had successfully broken through to the Martial Arts Second Realm, mastering the technique of Tendon and Bone Stretching!

In his excitement, he had changed into his night-running clothes and started racing around Dinghai City.

Once he started, he couldn’t stop, because after mastering the Tendon and Bone Stretching, not only had his strength increased, but his speed, endurance, and every other aspect had seen tremendous improvements.

With the added benefit of the Eight-Step Wind-Chasing Fist, Wu Liangchen’s Qinggong and Body Technique had become truly remarkable.

A single leap could carry him over ten meters, and then with just a slight push, he could leap again.

This feeling was practically the same as flying.

This was exactly why Wu Liangchen was so captivated.

Even though he had been running for nearly half an hour, Wu Liangchen didn’t feel tired at all. Instead, he felt energetic, his entire body seemingly filled with power.

He knew this was actually an illusion caused by the surge of power after his breakthrough.

After forcefully suppressing his excitement, Wu Liangchen was about to return.

But just then, he suddenly heard a faint whooshing sound from far away.

Thanks to his improved realm, Wu Liangchen’s five senses had also been greatly enhanced.

So despite the sound being extremely faint, he captured it with remarkable sensitivity.

His heart skipped a beat, because this was clearly the sound made by someone using Qinggong to run at high speed, and it seemed to be heading in his direction.

Wu Liangchen quickly darted into the bushes to hide.

Sure enough.

Just moments later, a dark figure flashed past the spot where Wu Liangchen had just been standing, then rushed down toward South City.

Wu Liangchen emerged from the bushes, his eyes flickering slightly.

Judging by the person’s running speed, their strength shouldn’t be too high, at least not as good as his own.

The key point was that they were heading toward South City, which was worth noting.

So after only a brief hesitation, Wu Liangchen followed close behind.

With his current speed and perception abilities, he didn’t need to follow too closely—just keeping distant tabs was enough.

This way, he could also avoid alerting his target.

Following this nightrunner, Wu Liangchen arrived at the South City area, where he saw the person standing on a rooftop, looking around, apparently searching for something.

Wu Liangchen stood at a distance, quietly waiting.

He wanted to see what this person was up to.

Finally, the nightrunner seemed to find his target and rushed toward the eastern part of South City.

Wu Liangchen frowned slightly.

The eastern part of South City—wasn’t that where he lived?

And critically, Yang Lian’Er had just moved there today.

So what was this person up to?

With this question in mind, Wu Liangchen quietly followed.

After passing through several streets and alleys, the nightrunner stopped in front of a dilapidated courtyard. After glancing around to ensure no one was watching, he leaped inside with a single bound.

Wu Liangchen quickly caught up and felt the courtyard looked familiar.

Suddenly.

A thought flashed through his mind.

Wasn’t this where the Bai family lived?

He had been here once before, so he remembered it.

This nightrunner coming to a young woman’s home in the middle of the night—his intentions couldn’t be pure.

Wu Liangchen thought how fortunate it was that he’d encountered this. Otherwise, something terrible might have happened.

He then lightly jumped onto the wall and peered into the courtyard.

At that moment, the nightrunner was crouching by a window, peering inside.

Then he took out what looked like an Immortal Crane Pot from his bundle and extended the spout through the window.

Seeing this from a distance, murderous intent rose in Wu Liangchen’s heart.

Without a doubt, this nightrunner must be the legendary "flower-picking thief"—a sexual predator.

The Immortal Crane Pot must contain something like Enchanting Fragrance.

Thinking this, Wu Liangchen suddenly kicked a piece of the wall, sending a brick fragment flying toward the nightrunner.

The nightrunner was fully focused on pouring the drug into the room when he suddenly heard a sharp whistling sound behind him. Knowing something was wrong, he quickly dodged aside.

CRACK.

The brick fragment shattered the door and window, creating a loud noise.

"Who’s there?" Old Bai shouted from another room.

The nightrunner turned to look and saw a dark figure standing on the distant wall. He was both shocked and angry.

Shocked that this person had nearly injured him with the flying brick, and angry that his carefully laid plan had been ruined.

But at this point, it was clearly impossible to continue.

So he leaped onto the roof, glanced back once, and quickly disappeared into the night.

Seeing this, Wu Liangchen smiled coldly.

He knew that the nightrunner’s last gesture was clearly a taunt.

Perfect—he hadn’t planned to let him go anyway.

With this thought, Wu Liangchen gave chase.

Meanwhile, Old Bai rushed into the courtyard with a cleaver, only to see a dark shadow fly overhead and vanish in the blink of an eye, leaving him terrified.

’Oh no, Erya!’

He hurried to his daughter’s room, finding that she was already awake, dressed, and sitting on the bed trembling with a pair of scissors in her hand.

"Father, what just happened?"

"It’s nothing, daughter. Probably just a passing nightrunner."

Seeing his daughter unharmed, Old Bai finally let out a sigh of relief.

And while the father and daughter were still in shock, Wu Liangchen and the nightrunner had already raced out of South City, heading straight for the outskirts.
