"Huff, huff, huff!"

Yukino Yukinoshita leaned tightly against the iron door, breathing rapidly. In her hand, she held a table leg wrapped in tape.

"What is all this?"

At this moment, her mind was in a state of collapse. First, she encountered a classmate killing monsters, then entered the Doomsday Game, being chased not only by zombies... but also by people.

Just now, she chose 'Yes' in the Doomsday Game option. Then she arrived here. Initially, there was also a person with dyed yellow hair, dressed like a thug, beside her. Later, they encountered zombies and were chased. The two fled and hid in a warehouse.

In the warehouse, the yellow-haired thug broke down. He muttered incoherent words. Finally, he even grabbed a knife and, like a madman, lunged at her, wanting to assault her, wanting her to fulfill his dying wish. Fortunately, she resisted in time, blocked the knife in his hand with the table leg, and escaped from the warehouse.

She had been desperately running for dozens of minutes. Along the way, there were also various zombies. She was almost surrounded and eaten alive by zombies. She was already exhausted from running. Everywhere were zombies, nowhere to go. Suddenly arriving in such a world and encountering such things, she was already physically and mentally exhausted. Her legs were weak from running. Her hands, which had been frantically swinging the table leg to attack zombies, were sore and trembling. She leaned weakly against the iron door.

Not losing her sanity in such a desperate situation was enough to show her mental fortitude, unlike that yellow-haired thug, who went crazy in less than an hour.

"That person was truly insane."

Thinking of such a crazy guy, and the terrifying zombies that were chasing her, Yukino Yukinoshita also felt fear in her heart.

"Hey! You're in here, aren't you?"

A frivolous and crazy voice came from next door. With a clang, the iron door next door was kicked open.

"Tsk, not here."

"!!!"

Yukino Yukinoshita's heart pounded rapidly. It was that lunatic! He had already found this side! Her trembling hands, raw from friction, tightly gripped the table leg. She dared not make a sound. She listened carefully. Footsteps walked past the door, without stopping. The sound gradually diminished until it disappeared.

"Did he leave...?"

She let out a long breath, immensely relieved that the other party hadn't discovered her. She had no strength left to resist now. If she were discovered, she would surely die!

Crack! Boom!

The classroom glass suddenly shattered! Yukino Yukinoshita spun around abruptly. That madman stood on the broken glass, his eyes fixed on her with a lecherous gaze.

"I found you."

"!!!"

She reacted, wanting to open the door and escape immediately.

"Smack!"

The blond hooligan's right hand pressed against the door, and she couldn't pull it open. He held a knife, pointing it at her.

"Don't come any closer!"

Yukino frantically swung the table leg in her hand. Unfortunately, her arm was already sore and weak. After swinging it, she nearly lost her balance. The table leg she swung was also soft and powerless. The blond hooligan easily caught it with his hand. With a pull, the table leg was snatched away and thrown to the side. His gaze turned to Yukino, pointing the knife at her, openly appraising her.

"What a beautiful girl. I didn't expect to get to play with such a top-notch high schooler before I die, hahahahaha!"

"You bastard criminal!" Yukino angrily rebuked.

This only further aroused his desire, and his expression became even more lecherous. "Hahahahaha, good scolding. Too bad there's no law here, only zombies. Don't worry, I'll make you feel really good, and then we can die here together after we're done."

Saying that, he reached out, trying to grab Yukino's tightly clasped hands over her chest. Tears welled up in Yukino's eyes, and she bit her silver teeth tightly. She didn't want to die, and she certainly didn't want to be defiled to death by someone else.

"Who can... save me..."

In her mind, the figure that released lightning in the darkness, killing monsters, and those striking golden eyes, involuntarily appeared.

"I won't allow you to bully my club members."

A cold voice sounded.

"Hmm? Who are you? Let go of me!"

The blond hooligan's hand, attempting to act improperly, was grabbed by a strong palm. Yukino turned her head and saw those familiar golden eyes and the expressionless Ren Kazama.

"You bastard, I told you to let go!"

The blond hooligan angrily swung his left fist at Ren Kazama's face.

"Be careful!"

Yukino, in a rush, kicked upwards with her right leg!

"Hiss oh!!!!"

Right on target! The blond hooligan immediately knelt on the ground in pain.

"..."

Ren Kazama silently watched this scene. The feeling of shattered eggs must be very painful. He reached out and pulled the stunned Yukino to his side.

"You... two... bastards!"

The blond hooligan shakily stood up, picked up a nearby table leg, and swung it at Ren Kazama.

"It's good for scum like you to die here."

Ren Kazama shook his head. Holding Yukino's hand, he moved past the blond hooligan, opened the door, and left.

"What!!!"

The blond hooligan was dumbfounded; his body couldn't move! Black, swamp-like, damp, cold, and sticky substances clung to his body. Gradually, he felt his body lose strength. His life force was being devoured by Five Thunder Rectification - Yin Five Thunder.

For those whose physical defenses are breached, their life force begins to leak away, and their heart and lungs fail to regenerate yang energy.

Fortunately, it taps into the kidney's water to draw the liver's qi, allowing the yin energy to take the lead in restoration. Once the yang energy is replenished, the refinement process begins. Its qi forms a black, viscous liquid suspended in mid-air. It's sticky and greasy, impossible to grasp, damp and cold to the touch. Unrestrained and free-flowing, it moves like mercury, seeping into every crevice. Dense and turbid, yet bizarrely fluid, it's capable of extracting bone marrow, sapping energy, and clouding the mind. Thus, in addition to unleashing black lightning, yin lightning also possesses the power of corrosion and the ability to devour life force.
