"Quick, quick—block the door!" Lei Rui screamed, rushing forward first.
Everyone else quickly swarmed over, bracing themselves against the two doors to hold them shut.
Beyond the two pounding on the doors, the group saw two more monsters in the hallway; combined with the one that had already been injured, there were three monsters outside. They were all slamming against the windows, shattering the glass and trying to force their way in.
"One person to a window!" Qin Jiagui shouted, gripping a chair tightly with both hands; whenever a green-skinned monster tried to squeeze through, he would smash it hard.
Su Yu also stood guard at a window, chair in hand. He struck twice but felt a numbing sensation spreading through his arms. Glancing at Qin Jiagui and another male student, he saw cold sweat beading on their faces—they couldn't hold out much longer.
The two doors were also shaking violently under the assault, with fine cracks gradually appearing on their surfaces; the situation was becoming increasingly dire.
"It's no use; we can't hold on. There are five monsters out there... It's over, we're done for..." Su Yu thought to himself. Only a dozen or so of the green-skinned monsters had broken in, yet five of them had charged straight to their classroom—he didn't know whether to call it a stroke of "luck" or simply a death sentence.
He watched the green-skinned monster before him: every time half its head squeezed through, Su Yu would smash it back, forcing it to retreat. It was futile. Suddenly, a wild idea flashed through Su Yu's mind, and he took a step back to the left.
The green-skinned monster slammed its heavy club against the iron window bars, warping the metal slightly, and once again attempted to squeeze through one of the openings.
This time, Su Yu didn't strike it; instead, he leaned to the side as if exhausted, resting for a moment.
Moments later, the green-skinned monster’s head slipped completely through the opening. "Su Yu—" Qin Jiagui happened to glance over and screamed in sheer terror: "Smash it! It’s crawling in!"
"It's fine." Su Yu took a couple of breaths. Watching as nearly half of the monster's body squeezed through in the blink of an eye, Qin Jiagui felt his limbs go weak with fear; if this immensely strong monster managed to get inside, they would all be done for.
Taking a deep breath, Qin Jiagui turned to help Su Yu strike the monster that had just begun to enter. Suddenly, Su Yu grinned and said, "Now's the time."
Gripping the chair tightly with both hands and exerting every ounce of his strength, he brought it crashing down heavily upon the monster—which was halfway through—and the iron bars of the window.
With a thunderous crash, the impact left Su Yu’s hands numb; he vaguely felt the skin between his thumb and index finger split open, but he had no time to care. It was a matter of life and death; like a madman, Su Yu rained blows down upon the monster.
Qin Jiagui was stunned at first, then suddenly realized what Su Yu had done.
Earlier, they had panicked and struck the moment the monster poked its head in, wasting their energy to no effect. By waiting until nearly half its body was through, Su Yu ensured the creature—whose body was only slightly smaller than the gaps in the iron grating—got wedged tight. Unable to advance or retreat, it was trapped helplessly, left to be battered by their blows.
Su Yu continued to smash the monster like a madman. Green fluid splattered everywhere, and the creature let out a terrifying howl as the wooden club dropped from its grasp.
Although it possessed immense strength, its body was still made of flesh and blood. Under the relentless pounding of the chair, its breathing soon grew faint; it slumped limply against the iron bars, losing all strength to move or struggle. "Die, you monster—"
Su Yu felt utterly drained as he delivered the final blow with the chair; with a sharp *crack*, the chair shattered into pieces, and the monster's head split open.
Then, Su Yu witnessed something extraordinary: from the monster's shattered skull emerged a glistening, dark object that resembled a crystal.
The moment it appeared, it shot—*whoosh*—straight into Su Yu’s left palm, which was closest to it, and then miraculously merged into his hand, vanishing without a trace.
Startled by what he had just witnessed, Su Yu instinctively recoiled. He looked at his left hand, but there was nothing there; had his eyes played a trick on him?
He looked up and saw that Qin Jiagui, having taken his cue from him, was attempting the same tactic: waiting for the green-skinned monster to squeeze part of its body through the window before smashing down on it.
Unexpectedly, however, the monster dropped its wooden club, gripped the iron bars with both hands, and—ignoring Qin Jiagui’s blows—hauled itself through the window and into the classroom with a powerful pull of its arms and a kick of its legs.
Only then did Su Yu realize that his previous victory hadn't been due to his own cleverness; the monster had simply been unlucky. The iron window frame had already been warped and distorted by the creature's own earlier attacks; while its upper body had squeezed through, its lower body had become wedged tight, leaving it immobilized—allowing Su Yu to score an easy kill.
As the green-skinned monster suddenly burst into the room, the students screamed in terror; a few female students, huddled together, were so frightened that their legs shook uncontrollably, and they lost control of their bladders.
Overcome by fear, Qin Jiagui stumbled backward and fell to the floor. The green-skinned monster seemed to harbor an intense hatred for Qin Jiagui; ignoring the wooden club lying on the ground, it extended its claws and lunged at his face and chest.
Given the monster's terrifying strength, a single swipe could easily crush Qin Jiagui's skull or even rip his torso wide open.
Just then, having finished off another green-skinned monster, Su Yu turned to see Qin Jiagui in peril; without a second thought, he grabbed a nearby chair and hurled it through the air.
