However, in the points list incident, everyone is united in gain and loss, Le Yu is certainly finding it difficult to move forward, but the other Sword Masters and sword scabbards are equally troubled.

In comparison, Le Yu actually benefits the most from this points list incident—after all, Qin Le Yin was already an open card sword scabbard, now that the other Sword Masters and sword scabbards are dragged down, it means they've been pulled to the same level as Le Yu, allowing him to defeat them with his extensive experience.

Ding—Dong—

With the end-of-class bell ringing, the first major class of the afternoon ends, and many students promptly leave the Tianhui teaching building. Some students head to the second major class, while others leave for classes in other buildings or head directly for extracurricular activities.

However, students usually attend classes on the first to third floors, while Le Yu is hiding on the fourth floor, unnoticed by anyone.

Because the fourth floor houses the teachers' offices and research labs.

Unlike Le Yu, who rolls away every six months as an elective teacher, the permanent lecturers have offices, and the largest office in the Imperial Academy belongs to Cha Huan's Platinum Tower.

Le Yu came to the fourth floor because he had asked Cha Huan offhandedly a few days ago, during a donation request to build a toilet, whether the Imperial Academy had lecturers researching Luminous Stone wireless radio.

It turned out Cha Huan told him the Imperial Academy has an entire group researching Luminous Stone wireless radio.

This was when Le Yu realized most of the wired telegraphs and audio systems circulating outside Huiyao were developed by the Imperial Academy. The Academy's wealth is largely due to holding numerous profitable patents, with many factories and guilds seeking collaboration, even scrambling for the leftovers that the Academy lets slip.

Like telegraphs, which are only a small side business, the Academy's significant earnings come from ancient industries: military, agriculture, livestock… In short, the Imperial Academy is akin to a large capitalist, reaping annual profits across Huiyao while lying in wait.

Yet the Academy often reinvests the earned money entirely into faculties and teaching, such as inviting celebrities for elective courses, with Qin Le Yin earning a not insignificant salary; or investing in social sciences research, like researching Combat Technique and emerging industries.

The wireless radio group is merely one entity wasting the Academy's vast teaching research funds, consisting of three educators.

Le Yu's interest in them stems from his suspicion that the Instant Annihilator 'Sound' is among these three wireless radio researchers.

Among the seven sword scabbards, the most dangerous is the Thousand Faces, and the most fearful is 'Sound.' Against an enemy with 'half-second instant annihilation' ability, even with the Ice Blood Physique, Le Yu cannot guarantee he can block 'Sound's' bullet completely.

The Thousand Faces is temporarily untraceable, but 'Sound' has one crucial clue: he uses Luminous Stone wireless radio for communication, and his equipment is likely quite advanced, not mass-produced. Therefore, how could Le Yu not suspect the scholars researching radio at the Academy?

Among them, Le Yu suspects the most the member of the wireless radio group leader, Tianhui department instructor, Yan Yi!

Yan Yi, acknowledged as the most beautiful teacher in the Academy, a white moonlight and red rose in the hearts of countless male students, and an admired figure among female students. Her beauty and status among students are illustrated by a popular post on the bulletin board: "I feel Teacher Qin doesn't match Teacher Yan."

Of course, Le Yu isn't familiar with Yan Yi, considering her just ordinary, since his heart has been captured by Qing Lan, perhaps never able to turn back from being a prude… After investigation, he concurs with the post: Qin Le Yin indeed doesn't match her.

According to records, Yan Yi was born into an official family, graduated from the Academy's Tianhui department, and stayed as a faculty because of her outstanding achievements, focusing on Luminous Stone academic research, donating all income to the Academy's scholarship fund, committed and dedicated to teaching, deeply loved by students, achieving the position as Tianhui department instructor at a young age—although Cha Huan also has motivations of using a beautiful teacher to encourage students' learning efforts.

Such a perfect woman with impeccable character, career, and morals, even makes Le Yu's heart flutter.

No, no, Le Yu doesn't want to marry her just for her body… Ah, not quite that meaning either, Le Yu wants to enter her body… Ah, exactly that meaning!

She's a supercar female that makes Le Yu want to "die and substitute" to experience thoroughly!

If she truly is the Instant Annihilator, Le Yu sorely wishes Qin Le Yin dies under a peony flower—he's not that eager to become a woman, but he finds it utterly irresistable for a beautiful sniper!

Le Yu is staking out now because he acquired the schedule of the Radiant Celestial Maiden. All the Sword Masters are off class in the afternoon after the first session, coinciding with the noontime list commotion, he's thinking the Sword Masters surely want to discuss with their sword scabbards—for example, at noon, Ming Shuiyun wanted to talk with Le Yu, but seeing him surrounded by many students, she simply slipped away.

What master, hmph, woman.

Hence, Le Yu can deduce, if Yan Yi indeed is 'Sound', then her Sword Master is likely to meet her now, and can do so openly—Yan Yi is a Tianhui department instructor, teaching "Situations and Policies", even if meeting the Radiant Celestial Maiden for a chat is entirely reasonable!

Reality didn't disappoint Le Yu: the long-skirted Yan Yi emerges from the instructor's office, unlocks and enters the adjacent electric research lab, yet soon hurriedly closes the door and leaves the lab, heading downstairs.

Did she meet her Sword Master below, this boldly?

Le Yu was about to follow, but his gaze is fixed on the ajar door of the research lab. He attempted entering this lab at night previously, but the doors were shut, the windows completely covered, and he didn't want to alert anyone—even more importantly, he didn't want to offend 'Sound'—he merely wants to uncover 'Sound's' identity to have a card up his sleeve when 'Sound' turns against him, but he absolutely cannot trigger confrontation actively.

Unless desperately necessary, he avoids conflict with the Instant Annihilator.

Le Yu's behavior generally can be termed as wanting power, yet wearing a helmet.

'Whom Yan Yi met downstairs, perhaps I can ask other students to know, but the chance to enter the research lab is rare…' As such thoughts swirl, Le Yu decisively approaches the lab, listened briefly feeling no presence inside, and ventured inside to explore.

The research lab matches Le Yu's impression perfectly: wires, keys, machines, the smell of oil… reminiscent of physics experiments while studying. Centered on the large table are two rectangular machines connected via cables to the Luminous Stone electrical box, beside it lies a notebook with an experiment report, Le Yu glimpses at it: "The Influence of Negative Feedback Technology on Signal Distortion."

What what what, what's written?

Without dwelling on minor specifics, Le Yu begins searching for evidence proving Yan Yi's identity, like the metal badge for remote communication Le Yu received, if he finds production traces or other versions in the lab, he could confirm Yan Yi's identity.

Drawers, crevices, cabinets… Le Yu searches swiftly and silently like a seasoned thief, sweeping through the lab like a gust of wind—the scavenging experience of Yin Yin Yin and Jing Zhengwei letting him swiftly adopt a thief's state, indeed, while doing inappropriate deeds, he gains much technical expertise.

"Hmm?"

While checking the drawer notebook, he finds a letter between its pages, the paper yellowing, evidently ancient. With a non-peeping privacy principle, Le Yu plans to glance briefly and determine its interest before returning it.

Upon seeing the signature, he freezes slightly.

"Brother Yan, stop, stop! You describe the brilliance of the Holy Sword extensively, but fail to mention where you saw the Holy Sword; you stress the destructive power of the Holy Sword, yet forget your pursuit of knowledge; you said you were exploring a part of the Academy, but don't mention it at all in the letter. You're poisoned by the Holy Sword, stop quickly, you've been discovered by the Sword Holder!

—Qin Xiao"

You've been discovered by the Sword Holder…

Perhaps it's the Ice Blood Physique activating, or perhaps the weather grows colder, as Le Yu silently memorizes this statement, a chill overtakes his spine, penetrating the bone.

Tap.

The footsteps outside the research lab sound like a thunderbolt stepping in Le Yu's heart.
