Doomsday: with unlimited warehouse system

"You guys find a room and remember not to leave this building," David said, handing over a healing crystal. Brian glanced at the crystal and swallowed the words he wanted to say.

Lily looked at the crystal in Brian's hand and gently tugged at his sleeve, whispering, "Let's go. It's already good enough to have obtained the crystal. They wouldn't dare to think too much about food and shelter. We've learned enough from the previous organization; they're reluctant to trust anyone too much."

David watched the two leave the room, then turned to Arnold. "Let's bring them some food tonight, enough for two people." Arnold nodded. After giving a few more instructions, Arnold returned to the room with Black and Sophie.

As soon as they opened the door, the system's prompt sounded.

[Mission: Doomsday Reserves! ]

["The doomsday is approaching. Please collect as many usable resources as possible and store them in the emergency storage space. During this mission, all the resources you store will receive a hundred thousand times critical hit. Time remaining: 0 days, 0 hours, 0 minutes. "]

[Mission Complete!]

"Congratulations on completing the mission. Please choose whether to open the completion reward package."

As the voice fell, a transparent panel appeared in front of David. It had two options, "Yes" and "No." David continued walking forward and chose "Yes" in his mind.

"Congratulations on receiving: 1 dose of gene-enhancing potion, 1 pair of night vision goggles!"

He was familiar with the gene-enhancing potion, but did the night vision goggles work just as their name suggested? He didn't have to worry about the darkness at the moment, as regular zombies had poor eyesight. However, with the appearance of mutated zombies, the night vision goggles came in handy.

Opening the inventory, he found the pair of night vision goggles right there. With a thought, the goggles automatically fitted onto his eyes. With the goggles on, David looked out the window. What seemed pitch black before now appeared as bright as day in his eyes, perfectly clear.

David took a few steps forward and leaned against the window, sticking his head out to look at the nearby tall building. He could clearly see a zombie standing on the building not far away.

Sally was curious about David suddenly putting on the goggles. It seemed that David's spatial abilities were quite convenient. Even the goggles could be worn directly on the eyes without needing to put them on manually.

Just as Sally was about to walk up to the window and say something, the night vision goggles happened to catch the sight of the zombie looking in their direction.

"Don't move," David said in a calm voice, quickly hiding himself below the window as well.

"Ah?" Sally was startled for a moment but quickly followed David's actions.

She watched David's nervous demeanor and was about to move towards him when a sound came from above her head. Something was at the window!

At that moment, right above Sally's head, outside the window, the zombie that should have been on the tall building suddenly appeared. It looked into the pitch-black room and tried to reach out and open the curtains, but the curtains were on the inside. The zombie let out a dissatisfied growl and wandered outside the window for a while before finally quieting down.

Sally listened to the noise above her head, not daring to even breathe. She remained on high alert, fearing that the zombie would break in directly.

After what seemed like an eternity, David stood up. He carefully looked towards the tall building again, and the zombie had returned to its original position. David breathed a sigh of relief and closed the curtains.

Seeing things at night was something he hadn't experienced in his previous life. This zombie seemed to be on guard duty, and if it noticed anything suspicious, it would likely notify its companions. Countless zombies would then flock towards their location. The night was indeed too dangerous. The growth rate of the zombies had been increasing rapidly.

David looked at Sally and reached out to pull her up. Sally's legs were weak, and she struggled to stand with David's help. But just a few seconds after standing up, she slumped softly towards David.

"David," she murmured his name.

David made a sound of acknowledgment and directly cradled her in his arms.

With the night vision goggles on, David had unimpeded vision in the dark room. After gently laying Sally on the bed, David took out a candle and lit it, placing it by the bedside.

"You went out for a while and actually found candles?" Sally exclaimed in delight.

David gently stroked her head and whispered, "Not only did I find candles, but I also got something good." As he spoke, David took out a crystal imbued with lightning powers. A crystal emitting a faint blue glow came into view.

Sally exclaimed, "This crystal is so beautiful!" Without realizing it, she reached out her hand towards the crystal imbued with lightning. For some reason, this blue crystal had been enticing her to absorb its power.

David observed Sally's actions but didn't stop her. Instead, he handed her the crystal. As soon as Sally's hand touched the crystal, it began emitting a blue light that gradually enveloped her body. She slowly closed her eyes and absorbed the energy from the crystal in her hand. Soon, Sally's forehead and body began sweating profusely. David took out a towel and carefully wiped away the sweat. After a while, Sally's complexion started turning pale, and she let out a painful groan.

"Ah!" Sally screamed, and David's heart skipped a beat. He quickly covered her mouth with the towel. If her scream attracted nearby zombies and David wasn't there, Sally would become their snack. Sally tightly bit down on the towel, curling up on the bed. She held her stomach and sweat had soaked the entire bedsheet.

David looked on nervously but was powerless to help. This was something Sally had to experience during the absorption process, and he couldn't do anything for her. About half an hour passed, and the voice of the system resounded.

[Congratulations, you have obtained a Level 2 Lightning Ability User. Now, the second task is being released!]

[Task: Crystal Storage!]

[There is one month remaining until the first major zombie outbreak. Please collect as many mutated crystals as possible and form your own team during this time. All the resources you store during this period will receive a hundred-fold critical boost. Task remaining time: 29 days, 21 hours, 5 minutes.]
