Doomsday: with unlimited warehouse system

While David was observing the intelligent zombie, the zombie was slowly approaching him. Compared to regular zombies, the intelligent zombie had a steady and powerful stride, with well-defined muscle lines visible on its body.

As the intelligent zombie walked, it opened its mouth and emitted a piercing sound. David forced himself to calm down and carefully observed every part of the zombie's body: the arms, chest, ribs, waist, ankles...

No matter where David looked, he could see a layer of skin that resembled hardened steel. It was evident that this wouldn't be his weak point, which made David increasingly impatient.

Seemingly sensing David's helplessness, the intelligent zombie continued to make sounds, and there was even a hint of excitement in its demeanor. In its eyes, this human before it was undoubtedly going to die today!

Meanwhile, Monica was on edge as well. Originally, she wanted to divert the attention of the intelligent zombie, giving David some time to adjust. However, her strength had not fully recovered yet. She could barely stand against the wall and could only anxiously watch David, hoping he would act quickly.

The piercing sound of the zombie grew closer to David, and he felt as if he could smell the putrid stench emanating from its decaying body with every blink of his eyes. He kept his eyes slightly closed, contemplating every part of the intelligent zombie.

As he listened to the increasingly near piercing sound, David seemed to have an idea. Suddenly, he opened his eyes and looked at the mouth of the intelligent zombie. At the moment when it opened its mouth to make a sound, he saw a completely different red flesh inside, devoid of any skin protection.

This spot was also connected to the intelligent zombie's brain. By launching an attack here, he could undoubtedly destroy its brain, thus depriving it of its intelligence and achieving a lethal blow!

"I found it! His weak point is inside the mouth!" David excitedly shouted.

At the same time, the intelligent zombie reached David and thrust its hand straight toward his chest!

Seeing this, David suppressed his excitement and quickly opened a portal using his spatial abilities. The void tore open, leaving a rift, and as a blurred figure passed through, David appeared next to Monica. The intelligent zombie's lethal strike missed its mark.

"I found it! His weak point is inside the mouth, where there is no skin protection! Only by attacking there can we reach his brain and kill him!" David excitedly exclaimed to Monica.

Upon hearing David's words, Monica instantly understood. Just now, she had also been observing the intelligent zombie, continuously searching for its weak point.

After hearing David's words, Monica looked at the zombie's mouth. Sure enough, it was a crimson color, and she could even see the tremors of the brain behind it.

At that moment, Monica felt a sense of admiration for David. To be able to analyze the zombie's weak point amidst such a crisis was not something an ordinary person could accomplish. However, a new problem arose. The intelligent zombie was too powerful. If they wanted to attack its weak point, they had to engage in close combat and even have someone to divert its attention.

However, besides Monica, the only one by David's side was Little Black. But at this moment, Little Black was still curled up on the ground, clearly affected by the previous attack. It wouldn't recover anytime soon. Monica herself was exhausted, unable to do much. When David appeared beside her, she couldn't hold on any longer and sat on the ground. In other words, only David remained.

"How about we retreat and call for backup?" Monica suggested, analyzing the situation at hand. However, David furrowed his brow and shook his head. He knew that if they didn't deal with the intelligent zombie right now, it would pose an even greater threat to the survivors in the future. After all, zombies were constantly evolving. If given time to strengthen itself once again, even a group of superhumans would be helpless against it. Therefore, they had to kill it today!

Without hesitation, David took a step forward, gripping his alloy dagger tightly. At the same time, he analyzed the environment in the alley. Due to the narrow space, when he used his spatial abilities to teleport, he could only move in three directions: forward, backward, and up. He couldn't move sideways. This made it easy for the intelligent zombie to see through his attack route and predict his position.

But at this moment, David didn't have time to consider all of that. He had to give it a try. David opened a portal, a bright light flashed, and when he looked again, he was already above the intelligent zombie's head.

David's sudden appearance immediately drew the attention of the intelligent zombie. It slowly raised its head and looked at David above, still emitting the piercing sound.

"Here's my chance!" David tightly gripped the alloy dagger and exerted all his strength to thrust it into the zombie's open mouth. However, the intelligent zombie reacted even faster. In the instant the dagger was about to touch its mouth, it quickly turned its body.

The alloy dagger collided with its skin, creating a series of sparks and the sound of metal clashing. David quickly retracted the dagger and used his spatial abilities to move once again, this time appearing directly in front of the zombie.

Feeling the pain in his hand, David was somewhat surprised. He hadn't expected this creature's defense to be so formidable. Even the alloy dagger couldn't do anything to it, and its reaction speed surpassed that of lower-level zombies, even surpassing some awakened superhumans.

"Darn it!" David said in a deep voice. It was clear that someone needed to divert the attention of the intelligent zombie while he seized the opportunity to attack. But now, he was the only one capable of fighting, and David found himself in a dilemma.

Monica frowned and nervously watched David. Just then, a furry figure suddenly flashed on the wall, accompanied by a familiar voice that David knew all too well. "Meow~"

David was taken aback. "Cola?" He quickly followed the sound and looked towards the wall. Indeed, he saw Cola sitting on the wall, seemingly yawning and looking at David.

"Cola, how did you get here? It's too dangerous. Leave quickly!" David quickly said to Cola, fearing that the intelligent zombie would notice it and attack. It would only make his situation worse. However, to David's surprise, after hearing his words, Cola glanced at him as if annoyed. This instantly confused David.
