Doomsday: with unlimited warehouse system

David glanced in surprise at the unexpected effect of Sally's lightning attack. He nodded silently and quickly shouted to her, "Keep using the lightning attack!" Sally nodded, tightly clasping her hands together. Sweat glistened on her fair face as she concentrated, her forehead covered in a thin layer of perspiration. However, just as she was about to unleash a new lightning strike, the towering zombie grabbed a nearby iron table and hurled it forcefully towards her.

Reacting swiftly, David opened a portal using his spatial manipulation ability and flashed to Sally's side, pulling her aside. This prevented Sally from releasing her lightning attack in time. Taking advantage of the opportunity, the towering zombie took menacing steps and charged towards Sally and David. Brian, seeing the situation, raised his seven blades to hinder its movement, giving David some time to react.

However, the towering zombie was a Level 3 zombie, and Brian was not capable of dealing with its strength. As soon as Brian reached the towering zombie, he was knocked down by a powerful punch. Fortunately, he was only hit by the force of the punch, or else he would likely have met his end there. It was at this moment that David regained his composure and recalled the significant impact of Sally's lightning attack. He improvised his plan.

He decided to let Sally take charge of the main attack while he searched for an opening around the towering zombie. It was crucial to avoid its mental control. Even though the towering zombie was only a Level 3, its strength was amplified by the dual crystals. That's why David had been eyeing the brown crystal in its eyes. If he could get hold of it, the towering zombie's power would weaken significantly.

David took out a primary crystal and had Sally consume it in advance to ensure she had ample energy later. Sally nodded and quickly moved to the side to start absorbing the crystal. By this time, Brian had also gotten up from the ground and stood next to David. "What's the plan now?" he asked, knowing he couldn't match the towering zombie's strength and putting his hopes on David.

"First, buy Sally some time," David said in a deep voice. The spatial blade materialized in his hand. Without wasting any words, David once again charged towards the towering zombie. But this time, he didn't intend to confront it head-on. With Brian's assistance, they continuously harassed the zombie. The real showdown would begin when Sally finished absorbing the crystal.

The spatial blade struck the towering zombie's shoulder, producing a crisp sound as the blade scraped against bone. The towering zombie raised its hand, preparing to unleash its mental control. David quickly performed a backflip, disappearing from its sight. Brian followed David's lead, constantly jumping around the zombie, waving his blades.

After a moment, Sally finally finished absorbing all the crystals. At this moment, both her physical and mental strength had reached their peak. Gazing at the towering zombie, which was engaged with David and Brian, Sally let out a soft shout. Suddenly, a lightning bolt thicker and more robust than before materialized in the void! The lightning snaked through the air, directly striking the towering zombie's shoulder!

Another thunderous roar echoed as the lightning forcefully tore a large gash in its shoulder, causing black blood to spray out like a fountain. David silently nodded, not expecting Sally's awakened lightning ability to be so formidable.

Brian also stared at Sally in astonishment, unable to conceal his amazement. The towering zombie reached out and touched the bloodied wound caused by the lightning. The blood seemed to agitate it, making it growl softly. It stared intensely at Sally, quickly raising its finger and pointing it towards her.

"Get out of the way!" David shouted and threw the spatial blade in his hand. The tall zombie had no choice but to dodge David's attack by turning his body. But at that moment, his finger suddenly pointed strangely at David.

"Oh no!" David cursed inwardly. He hadn't had a chance to prepare. If he was controlled by the tall zombie at this moment, given the distance between them, he believed he wouldn't have time to dodge.

Just then, Brian leaped over from the side and stood in front of David. Instantly, the tall zombie's finger pointed at Brian's forehead. Brian felt as if his body was immobilized, unable to move no matter how hard he tried.

At the same time, the tall zombie's fist appeared in front of Brian's eyes with no room for evasion.

"Boom!" Brian was struck hard in the chest by the punch! He flew up in the air like a kite with a broken string and landed heavily on the ground. He felt his body scattered, filled with pain. He struggled to stand up, but as soon as he got up, he fell heavily to the ground again. His lower leg had fractured from the previous fall.

David's brow furrowed. Clearly, Brian had just defended against the tall zombie's mental control for him.

"Meow!" Coke, who had been by Sally's side, suddenly let out a low growl and rapidly expanded its body! With a light leap, it arrived in front of the tall zombie and joined the fight. Sally no longer hesitated and lightning bolts kept exploding above the tall zombie's head one after another. In just a moment, it forced the tall zombie to kneel on the ground.

"A perfect opportunity!" A murderous intent flashed in David's eyes as he prepared to raise the spatial blade for a deadly blow!

But at that moment, the glass door of the building slowly opened. A pale corpse walked in mechanically. The three of them were startled by the sudden appearance of an inexplicable corpse. The corpse glanced at David and walked to the tall zombie's side.

"Roar!" The tall zombie roared at the corpse, and Coke in front of it also gradually shrank. The corpse's face gradually turned red, and its head slowly turned backward, while its body remained motionless in place. The tall zombie's head twisted 360 degrees!

The corpse stood beside the zombie, raised its hand, snapped its fingers, and thudded. The tall zombie's head rolled to its feet. It squatted down slightly, and its finger lightly brushed the forehead, revealing a crystalline object emitting a faint yellow light.

Wearing oversized shoes on its feet and holding the crystal in its hand, the corpse walked toward David. This corpse was incredibly powerful. David looked at the corpse, unable to move a muscle. The corpse approached him, brought its face close, sniffed David, and then its eyes brightened and its mouth slightly curved upwards. Subsequently, it handed the mental crystal it held to David!

Looking at the offered crystal, David was momentarily stunned. Why would this corpse give him the crystal? While contemplating, David's hand involuntarily reached out and accepted the crystal from the corpse's hand. As soon as David's hand touched the corpse's hand, he felt a chilling coldness. The mental type! The only ability that can control people is in the mental aspect!

David was deeply shocked. He maintained his outstretched hand until the corpse left, and then he regained control of his hand. Breathing a sigh of relief as he watched the disappearing corpse, David lowered his gaze to the mental crystal in his palm, full of doubt.

Is this corpse an enemy or a friend? If it's an enemy, a slight movement of its hand could instantly kill David, but if it's a friend, what is its intention? With a thought, David stored the two crystals in his hand into the spatial storage.

[You obtained one intermediate crystal, critical hit multiplier in effect! ]

[Congratulations, you obtained one hundred intermediate crystals! ]

[Attribute: Shadow type! ]

[You obtained one intermediate crystal, critical hit multiplier in effect! ]

[Congratulations, you obtained one hundred intermediate crystals! ]

[Attribute: Mental type! ]

Immediately after, David settled Sally and Brian on the side to rest. Then he began digging out the crystals from the fallen zombies one by one. Taking advantage of the fact that the surrounding zombies had been eliminated and no new ones would come for the time being, he quickly collected the crystals from the ground.

[You obtained one hundred and sixty primary crystals, critical hit multiplier in effect! ]

[Congratulations, you obtained sixteen thousand primary crystals! ]

[Attribute: None.]

Then, David hurriedly went to collect the crystals at the entrance of the building.

[You obtained sixty primary crystals, critical hit multiplier in effect! ]

[Congratulations, you obtained six thousand primary crystals! ]

[Attribute: None.]

David hadn't even seen how that corpse outside the door had acted, but a large number of zombies outside the door had already fallen.
