"Yes."

Si Cheng subconsciously replied, but vaguely felt that something was wrong, "What does Senior Sister want to do?" ”

Xia Lingge held a flashlight and kicked the zombies at will, she kicked open the shelves to block the zombies' group attack, and then dragged Si Cheng to retreat so that the group of zombies pounced, "Go find Xu Jiajia." She said succinctly, "Look at how she digs for treasure." ”

Si Cheng understood that she wanted to see the origin and usefulness of the purple crystal, and he couldn't hinder her, so he said, "Senior sister, go ahead, I'm fine." ”

Xia Lingge said: "If you can't support it, you must call me, Xu Jiajia can't go far, I can hear it." ”

Si Cheng softened his expression: "Okay." ”

Xia Lingge held a flashlight and started a large-scale sweep with a light source, except for a large number of zombie attacks here, that is, the vegetable and fruit area was very 'lively', she slapped the zombies with open teeth and claws, and a few jumps across the shelves to Xu Jiajia, Xu Jiajia bit the flashlight with her mouth, and held a sharp weapon in both hands that she found out of nowhere to dig at the eyebrows of the zombies.

The scattered purple crystals fell to the ground, emitting a glowing light, Xia Lingge took the flashlight and shone it for a while, but she did not help Xu Jiajia according to the original plan, but turned back to Si Cheng's side.

Originally, the two of them could only guarantee that they would not be injured when dealing with the zombie group, but now that Xia Lingge is gone, Si Cheng is alone, and it has become more and more difficult to deal with, and the flashlight in his hand has fallen somewhere, and he can only hear the howl of the zombies in the dark environment.

"Ahh

A zombie had imprisoned him.

He clearly felt that the zombie was about to bite down on his neck with its bloody mouth open.

'Whew-'!

There was a sound of a sharp blade piercing into something, and the zombie that had imprisoned him suddenly slackened its strength.

"Give."

Xia Lingge picked up the flashlight and handed it to Si Cheng: "Take it." ”

Si Cheng was a little surprised: "Didn't you go to help Xu Jiajia?" ”

"I've seen it." Xia Lingge accurately pierced the dagger in his hand into the center of the zombie's eyebrows, twisted and dug it, and its eyebrows fell out of gray crystals, but this crystal was not as crystal clear and intact as the amethyst in Xu Jiajia's hand, but it was broken instantly after being dug out.

Si Cheng looked at the zombies who had completely lost their ability to move, and suddenly understood: "These zombies have some kind of crystal in their heads that can drive them to move, but once the crystals are destroyed, they will also lose their ability to move, and thus die." ”

Xia Lingge nodded: "That's right." ”

Si Cheng frowned: "But why is the crystal Xu Jiajia holding purple and the one we found is gray?" ”

Xia Lingge thought for a while: "Perhaps, this is the difference between zombies." ”

However, it is indeed much easier for them to find the weakness of the zombies and deal with Qilai, as the zombies continue to die, the crystals that fall out are scattered, and there are always one or two that are purple.

Xia Lingge took those purple crystals in his hand and studied them.

"How are you doing?"

Xu Jiajia's voice came from not far away.

Xia Lingge replied, "It's okay." ”

The strong light of the flashlight shone on them, Xu Jiajia walked up to them and looked up and down, and said with some satisfaction in her voice: "It's not bad, it's not the kind of master who will drag his feet." ”

The purple crystal that Xia Lingge was holding flipped into Si Cheng's hand without a trace, and the flashlight inadvertently swiped down into the pocket of Xu Jiajia's somewhat bulging windbreaker.

The purple crystal could originally emit a subtle light in the dark, but it was still too weak compared to the light of the flashlight, so that it was not conspicuous when they chatted, but now Xia Lingge shone the flashlight on the crystal 'unintentionally', and the purple light was stimulated, even through the cloth, it was very dazzling.

"Sister Jiajia, what is this?"

Xia Lingge blinked and asked her like a curious baby.

Xu Jiajia looked stunned, she was hesitating whether to fool the past, Xia Lingge continued: "I watched Sister Jiajia kill zombies very skillfully before, she should have played the apocalyptic game more than once, right?" ”

The fluttering rhetorical question made Xu Jiajia dispel the idea of being confused, and she took out the crystals in her pocket and showed them in front of them: "This is the crystal, the material that may fall in the last days, and it can be regarded as a kind of benefit prepared by the game for players." ”

"Benefits?" Xia Lingge asked rhetorically.

Xu Jiajia nodded: "Yes." She shone her flashlight on the crystal, and the palm holding the crystal contracted slightly, only to see the purple crystal emit more and more light, and finally condensed into a trace of mist and disappeared into her palm.

"If you can absorb this material, you can achieve a tempering effect on your own skills, and it can be regarded as another upgrade method that does not require experience points."

"I see."

Xia Lingge and Si Cheng both nodded knowingly.

"But don't think about it if you don't have a natal skill." Xu Jiajia glanced at Xia Lingge, and then fell on Si Cheng, "As for you...... It's up to you. ”

Xu Jiajia picked up the plastic bag and continued to collect supplies, and when she walked a little farther, Si Cheng stuffed the hidden purple crystals into Xia Ling's singer: "Senior sister, try it." ”

Xia Lingge held the crystal, but the strange thing was that she didn't feel any special strange feeling that the crystal brought to her, she held the crystal tighter and tighter according to Xu Jiajia's appearance.

'Click-'

The crystals shattered.

"How can this be ......" Si Cheng was stunned.

Xia Lingge slowly let go of the hand holding the crystal, and the fine purple chip fell to the ground, but the color dissipated after a while.

"Is she lying to us?" Si Cheng couldn't help but let out a sound as he looked at the fragments that had turned into ordinary crystals, his slender brows furrowed, and his dark eyes revealed anger and murderous intent that even he didn't notice.

"Not really."

Xia Lingge looked at Xu Jiajia in the candy area: "It's not enough to lie, but she also specified that she didn't say everything, but the time limit of the apocalyptic game is seven days, and you can always know what went wrong." ”

Si Cheng also looked at Xu Jiajia, his eyes were cold.

Without the obstruction of zombies, the supplies were quickly collected.

As for the highest level, the fourth floor. They don't plan to explore anymore, the most important thing in the last days is materials, with materials and the rest of the things are negligible, it doesn't matter if you don't go up to the fourth floor.

Xia Lingge and Xu Jiajia walked down the stairs, and they wanted to appear in a conspicuous place for Chen Liang and them to see.

Si Cheng walked at the back and suddenly stopped: "Senior sister......"

Xia Lingge turned his head: "What's wrong?" ”

"Can I—Can I go to the bathroom?" Si Cheng said, "Don't worry, I'll be back in a while." ”

Xia Lingge hesitated to 'um'. Looking at the back of Si Cheng turning upstairs, he blinked a little puzzled, did he have any prejudice against the toilet downstairs?
