This coaching is not right.

Ito Sawa stood at the top of the stairs, his mental energy extending outwards like tentacles, trying to perceive a wider area.

However, he soon discovered that his mental power was still insufficient to cover the entire floor. To expand his sensing range, he needed more power.

He turned around, faced the students in Class B, and quickly made a few hand gestures.

The students immediately understood; they knew that Ito Sawa needed their mental energy to enhance his sensory abilities.

Without saying a word, the students of Class B silently began to activate their supernatural abilities, concentrating their mental energy on Ito Sawa.

These spiritual energies, like beams of light, attacked Ito Sawa.

His chessboard ability responded quickly, transforming the external spiritual energy into his own power. The chess pieces on the board seemed to be lit up, emitting an even more dazzling light.

As his classmates' mental energy joined in, Ito Sawa's chessboard could sense an ever-expanding range. He could feel his mental energy gradually expanding, covering more areas, and he could even perceive subtle energy fluctuations and hidden traces of magic.

Ito Sawa closed his eyes, focusing intently on perceiving everything around him. In his mind, a three-dimensional map made of mental energy was gradually taking shape, with every corner and every energy fluctuation clearly marked.

As time passed, Ito Sawa's mental energy covered the entire floor. Every detail of the floor became exceptionally clear in his mind. He could sense the teachers' locations and the actions of Class A.

Ms. Majima stood calmly in her seat.

Using his spying technique, he was able to see Ito Sawa's actions and the reactions of the Class B members.

He observed Ito Sawa's focused mental energy and formed a preliminary judgment about Class B's actions.

"It seems they are attempting a large-scale probe into the trapped formation."

He assumed that Class B was trying to detect other possible formations by enhancing their mental strength.

Therefore, he did not take immediate action, since Class B's actions were within his expectations and would be futile anyway.

He had only set up an amplification array; their painstaking investigation was in vain.

However, Mr. Majima was unaware of Itosawa's true intentions.

He never imagined that Ito Sawa actually planned to intercept the students from Class A in another stairwell.

If Mr. Majima knew this, he might reassess the situation and even abandon his terrain advantage to stop Itōsawa in advance.

With the support of the Class B members, Ito Sawa's mental power continued to expand, and the range of his chessboard-based sensory abilities grew wider and wider. He was able to clearly perceive the movements of Class A and the distribution of the teachers.

His mental energy was like a vast net, covering the entire floor. Although he didn't possess any spying techniques, he could still judge the movements of Class A by sensing the strength of their mental energy.

He discovered that among the people in Class A, right in the center of the crowd, there was someone with unusually weak spiritual power, but this weakness was surrounded by a dangerous aura that alerted him.

"Strange, the spiritual energy there is so weak, yet it makes me uneasy." Ito Sawa thought to himself, becoming more alert and increasing his spiritual energy in that location, intending to investigate it thoroughly.

Meanwhile, in the crowd of Class A, Sakayanagi Arisu, who was surrounded in the center, suddenly sensed something was amiss.

She turned to look behind her, a sharp glint in her eyes. She seemed to sense some kind of change, but there were no obvious magical fluctuations around her, leaving her uncertain.

Sakayanagi frowned; her intuition told her that something unusual might be happening. But after careful sensing, she found no trace of any unusual magic.

Ultimately, she decided to give up her doubts and believe that it might just be her imagination.

Although she abandoned her doubts, she still decided to take some precautions.

She casually set up a small spell. The spell was not complicated, but it was discreet enough to be triggered when someone approached, giving the other party an unexpected "surprise".

Her movements were stealthy and swift; those around her didn't even notice her subtle actions.

On the other side, Ito Sawa's spreading spiritual energy continued to weave, covering the entire floor.

Although his mental energy fluctuations were subtle and undetectable to most people, even the teachers, Sakagami and Majima, whose mental energy wasn't their forte, failed to notice them. However, they still caught the attention of Hoshinomiya-sensei and Chabashira-sensei.

Hoshinomiya-sensei had previously encountered Ito Sawa's spiritual power, and she quickly recognized this familiar feeling.

A flicker of surprise crossed her eyes, but she didn't say anything. Seeing Mr. Majima's serious expression, she decided to do something to help the students in Class B.

At the same time, Teacher Chabashira also noticed this fluctuation of spiritual power.

Unlike Hoshinomiya-sensei, she did not recognize that this was Ito Sawa's spiritual power.

But she didn't care. She just leaned against the door, looking forward to seeing what a spectacle it would be like when Sakagami-sensei and the students from Class A started fighting.

As for this spiritual force, as long as it's not directed at her, what does it have to do with her?

Ito Sawa was unaware that his mental abilities had been detected by his two teachers.

He remained fully focused, sensing everything around him, trying to find the best moment to act. His mental energy was like a lurking hunter, quietly waiting for its prey to appear.

On the A-class side, they moved quickly through the corridor without considering an ambush, because in their view, even if it was a teacher, they could fight back with so many of them together.

So, they headed to the top floor as planned, intending to seize the energy stone.

However, what they didn't expect was that Ms. Sakagami had already set up an ambush in the hallway. As they turned a corner, a large group of shadows suddenly surged out from all directions, attacking them like living creatures.

Sakagami-sensei possesses extremely powerful shadow abilities; he can manipulate shadows for both attack and defense. Caught off guard by the shadow's sneak attack, the two students in Class A are immediately in trouble.

But just then, Mr. Sakagami spotted Arisu Sakayanagi in the crowd, and a look of surprise flashed in his eyes.

It was then that Ms. Sakagami realized that Class A and Class B had not followed the route they had originally agreed upon.

He and Sakagayagi Arisu exchanged a glance, their eyes conveying a tacit understanding. Sakagami-sensei quickly made a decision: he would make the act real, using the shadows to intercept a few people, but deliberately letting the main force and the majority of Class A escape.

A hint of appreciation flashed in Sakagami Arisu's eyes; she knew that Sakagami-sensei had understood her intentions. Instead of stopping Sakagami-sensei, she signaled to the main force of Class A to continue forward, not to let this little incident waste their time.

The others didn't suspect anything either; they felt that it was enough for them to keep Sakagami-sensei occupied.
