Shen Jingqi and Xu An exchanged a glance, then nodded. "Alright, let's follow the senior's advice," Shen Jingqi said. So, the three of them headed towards the professors' office.

Along the way, students were coming and going on campus, their laughter and chatter echoing in the air. But Shen Jingqi and the others were in no mood to appreciate this usual scene, as their hearts were filled with worry and tension. The evil force was like a dark cloud hovering over their hearts, making it impossible for them to feel at ease.

When they arrived at the professors' office, they found several old, white-haired professors inside. They were gathered around discussing something, and when they saw Shen Jingqi and the others enter, they all looked up.

"Professors, we've encountered some trouble and would like your help," Shen Jingqi said, with a hint of urgency in his voice. Then he proceeded to recount their experiences on the mysterious mountain in detail to the old professors.

The old professors listened with faces full of surprise and seriousness. One of the professors, surnamed Zhang, stood up, pushed up his glasses, and said, "The legends of the Pure Power and the evil force, I have seen in some Ancient Books, but I didn't expect them to really exist. This evil force is extremely dangerous, and if it truly seizes the Pure Power, it could trigger a huge disaster."

"Then what should we do?" Xu An asked anxiously, rubbing his hands unconsciously, his eyes full of expectation. Professor Zhang pondered for a moment, then said, "The Pure Power you brought back requires a special training method to control. We can study it together to see if we can find a suitable training method. At the same time, you must also be careful of that evil force, as it might find you through various means."

Shen Jingqi nodded and said, "Alright, Professor, we'll be careful. Let's start researching now." So, they sat together and began discussing how to train the Pure Power.

Time passed by second by second, and the sky outside gradually darkened. But Shen Jingqi and the others didn't notice at all; their entire focus was on studying the Pure Power. Suddenly, Professor Zhang stood up excitedly, his eyes shining with light.

"I've got it! There's a method for training Pure Power recorded in an ancient secret manual, perhaps we could try it." Professor Zhang said, excitement in his voice. Then, he explained the training method in detail to Shen Jingqi.

Shen Jingqi listened intently, memorizing every detail. His focused expression seemed to engrave every word Professor Zhang said deep into his soul. Then, following Professor Zhang's instructions, he began attempting to train.

As Shen Jingqi closed his eyes, took a deep breath, and tried to concentrate on sensing the Pure Power within him, time seemed to slow and become heavy. Shen Jingqi could clearly feel his heartbeat, beating like a war drum. Suddenly, a wave of intense pain hit him, like surging tides overwhelming him in an instant.

"Ah!" Shen Jingqi couldn't help but let out a scream, his body trembling uncontrollably, beads of sweat forming on his forehead, rolling down his cheeks and dripping to the floor with a faint sound. He bit his lip so hard it bled, yet still couldn't suppress the piercing pain.

Meanwhile, Xu An encountered the same situation. Xu An's face turned ashen, like a sheet of white paper, his hands clenched into fists, knuckles white from force. He winced in pain, eyes wide as if they might pop out of their sockets. "What... what's happening!" he forced the words out through gritted teeth.

His gaze urgently turned to Professor Zhang, hoping for an answer that could free him from this painful abyss.

Professor Zhang furrowed his brow, his eyes reflecting worry and contemplation. He slowly said, "The Pure Power is extremely strong; your bodies may not yet be able to withstand its force. Stop for now, and let's think of another way."

Reluctantly, Shen Jingqi and the others stopped, their bodies still slightly shaking, as disappointment and frustration loomed over them like a dark cloud. Shen Jingqi lowered his head, his hands hanging limply by his sides, heart filled with defeat. "Can we really not control this Pure Power? Are we just going to watch the evil force seize it and cause disaster?" he repeatedly asked himself, each question stabbing his heart like a sharp knife.

Xu An collapsed to the ground with his hands on his head, his gaze empty. "It's over, everything's over; we're no match for that evil force." His voice was low and hoarse, laden with despair.

Just as they were immersed in despair, suddenly, the office door was slammed open with a loud "bang." The sound echoed in the quiet office like a thunderclap, tightening Shen Jingqi and the others' hearts.

A shadowy figure flashed in, moving incredibly fast, like a ghost. An aura of evil emanated from him, palpable, sending chills down their spines. Shen Jingqi and the others watched the shadow in terror, instinctively stepping back.

"Did you think you could hide here to train the Pure Power?" The shadow sneered, his voice low and hoarse, as if from Hell itself, carrying a chilling intent.

Shen Jingqi's heartbeat quickened suddenly, his eyes fixed on the shadow, filled with fear and alertness. "Could this shadow be sent by the evil force? What is his purpose?" he continuously speculated, each thought deepening his fear.

Xu An trembled more violently, his teeth chattering. "C-C-Could you... who are you? What do you want?" he mustered the courage to ask, but his voice trembled uncontrollably due to fear.

The shadow let out a sinister laugh, "It doesn't matter who I am; what matters is that none of you will leave here today." His eyes revealed a trace of ruthlessness and bloodthirstiness, as if Shen Jingqi and the others were already within his grasp.

Shen Jingqi took a deep breath, trying to calm himself. "Everyone, don't panic, let's figure something out." Although he said this, he had no confidence. He knew, facing this powerful shadow, defeating him was nearly impossible.

Just when they were tensely facing off, suddenly, a crisp voice rang out: "Don't be afraid, I'm here to help you."

Everyone turned towards the voice and saw Li Baiyu standing at the door. Her eyes were firm, a confident smile on her face. Shen Jingqi and the others felt they had found their savior, and a glimmer of hope reignited in their eyes.
