Doomsday: with unlimited warehouse system

"Run!" With a loud shout from Monica, she swiftly opened the door and rushed out, agile and quick.

David's heart skipped a beat as he also felt a strong presence at that moment. Without any hesitation, he immediately took care of everyone and urged them to run. The people inside the room finally realized something was wrong and rushed towards the door. Just as the last person, Arnold, dashed out, there was a loud noise from inside the room. It seemed like something had broken the window and rushed in!

David picked up an alloy short knife and approached the door. The closer he got, the heavier and clearer the breathing sound became in his ears. Something had entered. He turned his head and looked at Monica.

Monica furrowed her brows tightly, already gripping a seven-headed weapon, in a state of alertness all over her body. Although she had only faced this woman in front of her three times, given the current situation, she knew it was no joke.

Sally had also walked up to David's side by now. She glanced at Monica beside her and raised her hand, causing several purple lightning bolts to leap from her fingertips. The lightning flickered, appearing powerful. Monica was slightly surprised but continued to cautiously watch ahead.

David also tightened his grip on the alloy short knife and stood guard next to Sally. Just when everyone was tense, there was a crackling sound from inside the room, indicating movement. David turned his head and waved his hand at Arnold. Arnold nodded and went ahead, patting Duke's shoulder before walking with Sophie towards the back.

This time, Arnold understood David's silence very well. Immediately after, David lowered his gaze, patted Sally's shoulder, and gestured towards the room. His unspoken meaning was for Sally to leave this place first. After all, they didn't know what kind of monster was in front of them, and he had to protect Sally's safety.

Sally glanced at David, then looked at Monica beside her. She resolutely shook her head. David gave a helpless smile, knowing that Sally was getting stubborn with Monica. He decided not to say anything further, just lowered his head and quietly told her to be careful.

Sally nodded, and the purple lightning on her fingertips began to snake around. David had great confidence in Sally's abilities. As a third-level electrokinetic, she was capable of confronting most of the zombies. Monica watched this scene, raising an eyebrow.

Just then, a hand suddenly reached out from the room and grabbed the doorframe! Monica's heart trembled, unable to react in time.

Just as the hand was about to reach her, David raised the alloy short knife and fiercely swung it at the hand. Instantly, a severely decayed hand was severed and fell to the ground. Then Sally conjured a bolt of lightning in the air, directly reducing it to ashes.

Monica finally breathed a sigh of relief, and her gaze at Sally became serious. She hadn't expected Sally's reflexes to keep up with David's pace and that her strength seemed to be on par with her own.

At this moment, Arnold had led everyone to close the room, leaving only David, Sally, and Monica in the corridor. The low growls of the zombies occasionally echoed. David had already realized that the zombie was nearing the door!

"Follow up with my attack later and unleash your lightning!" David whispered to Sally.

Sally nodded with a smile. Then David turned to Monica and said, "Let's fight side by side this time. Let me see your strength."

Monica rubbed her arm and raised an eyebrow at David, implying that he should just watch. So the three of them continued to wait at the door for the appearance of the zombie. But the zombie seemed to be playing hide-and-seek with them. After more than ten minutes, there was still no sign of it, which instantly furrowed David's brow. If this continued, they wouldn't know the zombie's location and couldn't launch an effective attack.

Monica made a bold decision. She quickly reached into the room, attempting to draw the attention of the hidden zombie. David watched her actions, tightly gripping the alloy short knife in his hand.

Before Monica could fully retract her hand, the zombie inside the room suddenly protruded its head. When it saw Sally and David, its mouth split open. "Found you."

David's whole body stiffened! At the moment the zombie raised its hand, he swiftly embraced Sally's waist and quickly pushed her away!

When David stood steadily in the corridor, holding Sally, the zombie had already stepped out, and its hand had created a large pit where they had just been.

"This zombie just spoke?" Sally stared at it in disbelief, not expecting that a zombie could speak and that it sounded so fluent, almost like a normal human.

David observed the zombie closely. It appeared no different from an ordinary zombie, but after experiencing the red light, its size had increased several times. It was even taller than the room's doorway.

"This zombie is not low-ranking, be careful," David whispered. It was more than just not low-ranking. This zombie's stage seemed to have mutated a second time on top of being a mutated zombie itself. Otherwise, how could it speak? How could it suddenly attack?

An intelligent zombie was quite troublesome to deal with! The zombie looked at the chattering pair in front of it, imitating the appearance of humans, and licked its lips. "Food, food..." it muttered, then in the next second, it charged towards David and Sally's position!

"Attack!" David shouted at Hong and Sally. Immediately, he summoned his armor and wielded the alloy war blade, firmly blocking the zombie's attack with his hand!

"Crack!" Sally raised her hand, and a dazzling lightning bolt appeared above the zombie's head. Her gaze was determined as she focused her consciousness, rapidly striking the zombie with several bolts of lightning!

"Ah!" The lightning struck the zombie, causing it to cry out in pain, taking a few steps back. The areas where the lightning hit its body emitted wisps of burnt smoke.

"Lightning!" The zombie touched the painful areas and roared in anger. turned and looked at Sally, In the next moment, the zombie rushed forward.

Oh no! David quickly tore open a spatial rift beside Sally and used telekinesis to push her inside. Sally only felt a force pushing her, and when she appeared again, she found herself inside the room!

"Sally?" Arnold looked at the sudden appearance of Sally in front of him, surprised. Then, as if realizing something, he quickly asked, "What's happening outside?"

Meanwhile, Sally stood still, looking around the room. How did she end up being sent here directly? Did David's abilities level up again?

Outside the room, David watched Sally disappear and let out a sigh of relief. He was just testing his luck, but unexpectedly, his abilities had also advanced with the arrival of the fourth level.

"Where is she?" The zombie became even angrier when it saw the person vanish. In the next moment, it disappeared and reappeared behind David at an incredible speed.

"Hey!" Monica, who had been waiting for an opportunity, raised her gun and quickly aimed at the zombie behind David, pulling the trigger.

Bang! The bullet accurately hit the zombie's eye. "Ah!" The painful cry of the zombie came from behind David. David quickly turned around, glaring fiercely at the zombie in agony. He could sense that the aura and reactions of this zombie were different from ordinary ones, and it was even faster.

Is this the zombie's second awakening? Taking advantage of the zombie's pain, David quickly distanced himself from it. The corridor was not suitable for a fierce battle. If things escalated, the entire building might collapse.

But outside... David looked up at the sky. His pupils dilated. When did the red light recede? As the zombie recovered, and before it disappeared again, David rushed out while shouting, "Go downstairs and fight!"

With that, Monica saw David jump directly from the corridor! Fortunately, it wasn't a high floor. Plus, considering David's current physical condition, jumping down from the corridor was no problem for him at all.

David landed and rolled with the momentum before swiftly getting up. He turned his head, and Monica followed suit, carefully jumping down from the balcony.
