Chapter 73: Dimensional Space Upgrade! (1)

The moment the glass shattered, Liu Yun, Lan Zuancheng, and Gu Zhenwei froze on the spot. They held their breath and hurriedly scanned their surroundings.

When they saw no zombies nearby, the three of them let out a sigh of relief.

Patting her chest, Liu Yun whispered with a small grin on her face, "I didn’t expect the sound of shattering glass to be so loud."

Lan Zuancheng grimaced at her words. "Me too."

After the brief tense moment, Lan Zuancheng carefully broke the remaining glass in the window. He then took out a thick cotton towel from his backpack, laid it on the windowsill, then turned to Liu Yun.

"Come on. I will help you in."

Grabbing Lan Zuancheng’s hand with her right hand, Liu Yun stepped onto the windowsill, then grabbed the wall with her left hand.

Behind her, Gu Zhenwei held her waist and said, "I’ll count to three."

Liu Yun nodded, then Gu Zhenwei began to count, "3... 2... 1!"

At the same time that Liu Yun pulled herself up, Gu Zhenwei lifted her. With Lan Zuancheng supporting her hand, Liu Yun smoothly climbed into the small security post.

Landing on the floor covered with shattered glass, Liu Yun quickly walked up to the wall and grabbed the keys.

Without wasting any time, she quickly handed the key to Lan Zuancheng, then pulled a folding metal chair toward the window.

Stepping onto the chair, she grabbed Gu Zhenwei’s hand, then climbed out of the window.

"Let’s go."

With that, the three of them quickly went to the metal gate.

Standing on either side of Lan Zuancheng, Gu Zhenwei and Liu Yun vigilantly scanned their surroundings while Lan Zuancheng tried the keys one by one.

A few minutes passed in a tense atmosphere before Lan Zuancheng found the right key.

Click!

"Come on." Lan Zuancheng said as he took out the metal lock and pushed the gate open.

Leading the way, Gu Zhenwei kept his guard up. Holding the baseball bat, he vigilantly checked every intersection and corner.

Before long, the three of them reached the first warehouse in Area B.

Liu Yun stepped forward and checked the door. She saw that it used an automatic locking system.

Frowning slightly, she turned to the others. "What should we do now?"

Lan Zuancheng pressed his ear against the metal door, then focused on his hearing.

After a brief moment of silence, he said, "There is no sound of movement. There should be no zombies or survivors inside."

Looking at him, Gu Zhenwei hesitantly asked, "Should we break the door?"

Since they had no key, breaking the door was their best option right now.

"Mhm. Let’s break the door."

Receiving his agreement, Gu Zhenwei grinned lightly. "It’s my turn now. You two, step back."

Knowing that Gu Zhenwei was the strongest among the three of them, Lan Zuancheng and Liu Yun obediently took a few steps back.

Raising his baseball bat, Gu Zhenwei clenched the handle, then swung it toward the metal door’s handle.

Bam!

Liu Yun’s heart skipped a beat when the banging sound echoed through the silent surroundings.

Clenching her hands, she nervously looked around. While she was checking the surroundings, Gu Zhenwei raised his baseball bat again and swung it at the metal door once more.

Bam!

Crack!

This time, the metal door’s handle cracked from the impact.

Seeing this, Gu Zhenwei’s eyes lit up. He examined the door for a moment, then raised his leg and kicked the damaged area.

Bam! Bam!

Gu Zhenwei kicked it a few times before he finally managed to break the door open.

Watching him kick the door open, Liu Yun swallowed hard. ’This man... his smiling face doesn’t match his strength at all!’

Not knowing that Liu Yun was shocked by his strength, Gu Zhenwei carefully pushed the metal door open, then stepped inside.

Dim sunlight shone through the small windows and the exhaust fan opening in the ceiling, illuminating the dark warehouse.

The moment the three of them went inside, they stepped onto the floor covered with a thick layer of dust.

Choked by the dust, Liu Yun coughed violently. "Cough, cough, cough!"

Covering his nose, Lan Zuancheng said, "Cover your nose. It’s too dusty here."

Following his suggestion, Liu Yun covered her nose with her hand.

Splitting up, the three of them carefully checked the warehouse. A few minutes later, they gathered again.

Walking up to Lan Zuancheng, Gu Zhenwei said, "This place is clear. No zombies or humans."

"Good. Let’s collect the supplies." Turning to Liu Yun, Lan Zuancheng added, "Younger Sister Liu, you can collect as much as you can fit in your space."

"Got it."

With that, the three of them split up again. While Lan Zuancheng and Gu Zhenwei filled their backpacks with canned food, Liu Yun directly put the boxes of canned food into her Dimensional Space.

In less than ten minutes, she had filled up her space and looked at the remaining supplies with regret in her eyes.

Unwilling to pass up this good opportunity, Liu Yun asked inwardly, ’System, can you tell me how to upgrade the Dimensional Space?’

At her question, the System’s mechanical voice rang in her mind.

[There are three ways to upgrade the Dimensional Space.]

[First, the Player can buy an upgrade card from the System Store when it is available. Second, the Player can feed the Dimensional Space with energy. Third, the Player can spend Celestial Stones for an instant upgrade.]

Listening to the System’s answer, Liu Yun rolled her eyes. ’I knew it! This System is always eyeing my Celestial Stones!’

Liu Yun thought for a second, then asked, ’What kind of energy can be used to upgrade the Dimensional Space?’

[Player, the crystal cores in this world contain mental energy. However, they contain a lot of impurities.]

Liu Yun frowned slightly, then asked further, ’Then, are there other kinds of energy that I can use to feed the Dimensional Space?’

The System fell silent for a few seconds before saying, [The player can use all kinds of energy you can find.]

When Liu Yun heard this, she scratched her cheek and thought, ’I seem to have read about different kinds of energy before... But where?’
