Doomsday: with unlimited warehouse system

After Sally returned to the room with the ten crystals, she began to absorb them. The door was not closed, and David sat on the living room sofa, observing Sally's condition.

"Meow." Cola walked over and rubbed David's ankle with its head.

"Hey, Cola." David said and picked up Cola. Seeing Cola looking pitiful, David smiled helplessly, guessing that the little guy was probably hungry. With a thought, he took out ten shadow crystals from space and placed them in front of Cola. As soon as Cola saw the crystals, its eyes lit up.

David smiled faintly and put Cola down. Just as he settled Cola, Little Black hurriedly walked over. While David was giving crystals to Cola, Little Black had been watching eagerly. If Cola had something, how could it be left out? Little Black made a low humming sound in dissatisfaction and imitated Cola by rubbing its head and body against David.

"These two troublemakers." David complained and took out twenty primary crystals. So far, he hadn't come across any zombies with the same attribute as Little Black. If he could find zombies with crystals on their foreheads and collect them, Little Black's upgrade would probably be even faster.

When Little Black saw the crystals, it quickly ran and brought its own dog bowl. It carefully placed it on the ground and watched as David put the crystals into the bowl. After happily spinning a few times, Little Black finally started absorbing the crystals.

After about an hour, the cat and the dog in the living room had absorbed the crystals and fallen asleep. When David looked towards the room, Sally had finished absorbing all ten crystals in front of her. She was now exhausted and fell asleep on the bed.

David stood up and walked into the room. He carefully picked up Sally again, placed her back on the bed, and adjusted her sleeping position. After covering Sally with a blanket, he walked out.

Just as he stepped out of the room, he heard a knocking sound on the door, accompanied by Arnold's voice, "David, it's me."

David walked over. Unbeknownst to David, just a second before the knocking sound, Cola, who was sleeping on the sofa, slightly opened its eyes. As soon as David opened the door for Arnold, Cola closed its eyes again.

"David." Arnold's eyes lit up when he saw David. David nodded and let Arnold in. After entering, Arnold relayed the task David had given him, "That Lily, even after coming out, couldn't heal the injuries of that young man."

Listening to Arnold, David nodded. It was expected that the injuries couldn't be healed. It seemed that a few crystals weren't enough for an upgrade. If there had been an upgrade, Lily could have easily healed Brian's minor injuries with a flick of her finger. But for now, Lily couldn't upgrade yet. David's gaze turned indifferent, then he looked at Arnold.

The second batch of awakenings is also approaching, and it's time for Arnold's werewolf attribute to emerge. "If anything feels off lately, come find me promptly," David said. Arnold hesitated. What could possibly make him uncomfortable? Although he didn't understand what David meant, he nodded in agreement.

Ten days quickly passed. During this time, David had been hunting zombies outside. However, all the zombies he encountered were low-level ones, and he had only seen three second-level zombies. Even those three zombies had primarily low-level crystals.

"David, come and see Arnold's condition!" The knocking on the door continued. David woke up abruptly from his sleep, opened the door at a fast pace, and raised a finger to his lips to silence Sophie's voice.

After David had cleared out most of the nearby zombies recently, he couldn't guarantee that zombies wouldn't come from elsewhere. It was better to be cautious. Sophie looked at the red tint in David's eyes and lowered her voice.

"David, something's not right with my husband."

Arnold's transformation had started early in the morning? Did the second awakening time vary from person to person? David nodded and carefully closed the door, following Sophie back inside their home. As soon as he entered, David was startled by the mess on the floor.

And there was Arnold, kneeling on the ground. He looked extremely distressed, and even his hands had begun to transform into claws.

"David," Arnold spoke with a hint of a wolf's tone. Seeing this, David felt that something was off. In the previous timeline, he hadn't witnessed Arnold's awakening. On the day Arnold awakened, David had gone out for a while, and when he returned, Arnold told him about it.

Sophie stood beside them, furrowing her brow, seeking David's help. "David, look at Arnold's condition, please help him."

Seeing Arnold's painful expression, Sophie was deeply concerned. She had tried to approach him but was growled at and pushed away. Arnold struggled and insisted that she call for David's help, so she went to fetch him.

David frowned. He couldn't help with this task. He could only guard the door. If anything unexpected happened, he could intervene.

Arnold's awakening this time was completely normal. Becoming an Awakened was a necessary path for him.

"Sophie, don't worry. Arnold will be fine. I'll stay here and keep an eye on him," David reassured her. He sat down nearby, just a few steps away from Arnold.

Arnold started to transform into a full werewolf, lifting his head and letting out a howl. As Arnold completely transformed and became uncontrollable, he began attacking things around him.

After half an hour, Arnold gradually regained his senses. He looked around at the chaotic environment and froze. Then he turned his head and looked at David sitting calmly beside him. He spoke, "David, I..."

Before he could finish his sentence, David stood up with a gratified expression and said to him, "Congratulations, you have successfully awakened."

"I... I awakened successfully!" Arnold exclaimed excitedly. He had finally awakened! Seeing everyone around him with superhuman abilities, he often felt useless to David. It made him eager to join them. Now, he had finally awakened! It was fantastic!

Arnold lowered his gaze and looked at his werewolf state. He quickly went to find a mirror and returned shortly with a furrowed brow. "But, David, how can I revert this?"

David sighed and said, "Focus your consciousness and think about returning to your original form."

Arnold nodded, closed his eyes, and furrowed his brow. After a while, his werewolf form gradually receded.
