Gu Yunqi charged forward, his figure like a swift wind, with the bright samurai sword across his side, instantly appearing in front of Lu Yu!

"Boy, die!"

As he arrived before Lu Yu, Gu Yunqi coldly said, his words emitting an incomparably sharp aura!

This aura was like a blade edge, not yet striking out but already giving a sense of danger!

After saying this, Gu Yunqi twisted his wrist, and a dazzling ray of cold light instantly burst forth from the samurai sword in his hand!

This cold light, upon bursting forth, carried a hint of chilling murderous intent!

Seeing the blade from Gu Yunqi, Lu Yu's eyes widened suddenly, feeling a trace of danger in his heart!

Not good!

Sensing the danger, Lu Yu's heart shook, then he bent his knees, exerted force abruptly, and with a firm push off the ground, his body shot backward rapidly like a monkey!

Although Gu Yunqi's strike was extremely fast and fierce, Lu Yu could still clearly see its trajectory!

Lu Yu dodged because of Gu Yunqi's Yin Blade Technique!

Although the Yin Blade Technique looked similar to ordinary swordsmanship, it could send out an invisible airflow upon striking, which was its troubling aspect!

This airflow, invisible to the naked eye, could only be felt personally, making it elusive, often turning deadly!

Sinister and treacherous, harming when least expected, hence the name Yin Blade Technique!

"Trying to escape?"

Seeing Lu Yu retreat swiftly, the corner of Gu Yunqi's mouth showed a cruel shade, and he fiercely slashed the samurai sword in his hand toward Lu Yu!

Slash!

With this slash, the air emitted a strange swishing sound, akin to wailing spirits, chilling the heart!

As this fierce slash cut out, an invisible airflow quickly surged toward Lu Yu's chest, now even Lu Yu could sense a sharp airflow rapidly approaching him!

Feeling the sharp airflow approaching, Lu Yu's eyes flickered with brilliance, and as he landed, his body swayed, agilely dodging the incoming airflow like a willow caught in the wind!

Whoosh!

As Lu Yu dodged this airflow, a sound came from the wall behind him.

A glance showed a slash mark on the upper wall, about ten centimeters long, clear to see!

Seeing the slash mark, Lu Yu's heart slightly jumped!

The distance between him and Gu Yunqi was merely seven or eight meters; although the mark seemed terrifying, to Lu Yu it was superficial!

Despite its length, the slash mark was shallow, unmatched to Gu Yunqi's earlier fierce strike!

Witnessing this, Lu Yu instantly understood!

The Gu family's so-called Yin Blade Technique's airflow diminished in power with distance, weaker the farther it went!

Realizing this, Lu Yu understood why Gu Yunqi was so fast!

Gu Yunqi's rapid body technique aimed to dramatically reduce distance to maximize the Yin Blade Technique's power!

"Hmph!"

With this in mind, a cold smile appeared on Lu Yu's face, slightly moving his body, looking at Gu Yunqi with contempt in his eyes!

"Why are you laughing?"

Seeing Lu Yu's cold smile, Gu Yunqi coldly said, his gaze emitting cold light, revealing an icy shade!

Lu Yu's contemptuous smile made him furious!

"Why am I laughing?"

Upon hearing this, Lu Yu shook his head, then fixed his gaze on Gu Yunqi, saying: "I'm laughing at the numerous flaws in your Gu family's Yin Blade Technique, it's mediocre!"

His words carried a cold smile, his eyes filled with disdain.

"Mediocre?"

Hearing Lu Yu's words, Gu Yunqi's eyes grew colder, slowly raising his samurai sword, saying: "Such arrogance, aren't you afraid of biting your tongue!"

His words showed presence of fury: "You claim my Gu family's Yin Blade Technique is mediocre, today I'll show you the power of the Yin Blade Technique!"

His words inadvertently revealed anger, his figure flickered and charged at Lu Yu!

But this charge differed from the previous ones.

Gu Yunqi's prior charges grew faster and fiercer, evidently aiming to kill Lu Yu with a single strike!

This time, his speed remained swift but slower than before, causing momentary bewilderment!

As he reached Lu Yu, he fiercely slashed his samurai sword, sending an invisible airflow at him!

After the slash, Gu Yunqi did not stop, tapping the ground again, his body blurred, moving to Lu Yu's other side.

Upon arriving on Lu Yu's other side, Gu Yunqi swung his sword again, sending another airflow at Lu Yu!

In that moment, Gu Yunqi moved four times, striking four airflows from different positions; very close, the airflows fiercely rushing at Lu Yu!

"Couldn't finish me in one strike, resorting to a continuous attack?"

Seeing this, Lu Yu's eyes flashed coldly, his muscles tensed, filled with strength: "Smart!"

"This time, let's see how you dodge!"

Gu Yunqi coldly smiled, slightly bending his knees again, holding the samurai sword sideways, eyes like a hawk staring at Lu Yu, waiting for him to dodge and reveal an opening!

Feeling the airflows slashing from four directions, seeing Gu Yunqi poised to strike, Lu Yu's eyes glinted with brilliance, quickly exerting force and moving instantly!
