In this post-apocalyptic world, I unexpectedly became a star galaxy master.

"Crystal core? To upgrade your ability level?" the crowd exclaimed.

"Hmm, you guys don't even know this?" Hong Tang deliberately looked at the four of them as if they were idiots.

"Is this real? There really are crystal cores inside zombies' heads?" Xu Yang's expression was bewildered. No wonder Jiang Hua and the others improved their strength so quickly, as did the team members who left.

The base has been collecting crystal cores, which can be exchanged for points and food, but they haven't revealed that crystal cores can improve ability levels. Why is that? And how did Hongtang know that? She's not an ability user.

What's most infuriating is that despite killing so many zombies, he and his teammates didn't collect any crystal cores—it's a complete waste!

"Zombies, like superhumans, can evolve. The higher the level, the higher the energy of the crystal core. The crystal cores of zombies with different abilities are also different colors."

"The official information has not yet been released regarding the function of the crystal core, which is probably still in the research stage. After all, the crystal core is taken from the brain of a zombie, and there may be some residual zombie virus inside, which may pose some potential harm to the human body."

“That makes sense, but how do you know all this?” Li Xiang asked, voicing his question.

Hongtang gave him another approving look; this person seemed more suitable to be the captain of this squad.

"I have my own channels. Believe it or not, it's up to you."

"Believe, believe, believe! They may not believe you, but I do!" Liu Xinnan declared first. Her space was only a dozen square meters. If the crystal core could improve her ability level, wouldn't her space be incredibly large in the future?

"Sister Hongtang, how do we upgrade the crystal core?" Liu Xinnan asked humbly, gazing longingly at the crystal core in Hongtang's hand, as did the other three.

As for the potential dangers that Hongtang mentioned, they automatically ignored them.

Hongtang handed four transparent, attribute-less crystals to the four people, saying, "Hold the crystal cores in your hands, use your special abilities to sense the energy within and absorb it."

The four of them accepted the crystal core with some skepticism and then tried it out according to Hongtang's instructions.

Soon, Xu Yang was the first to finish absorbing the crystal core, and the originally transparent crystal in his hand turned into a clump of gray powder. He said incredulously, "The crystal core really can enhance superpowers. I feel a warm energy entering my body, and my metal-type superpower seems to have improved as well."

"Yes, yes, I felt that warm current too. My spatial ability can be improved, and I can store more things in the future," Liu Xinnan said happily.

Li Xiang and Lin Yao also finished absorbing the energy and looked at Hong Tang with gratitude.

"Crystal cores of the same attribute can increase your ability level faster, but the zombies with abilities are also more powerful," Hong Tang kindly reminded them.

"Someone's coming. Let's leave first." Sensing that a group of people were approaching, Hongtang took the lead and stepped into the darkness.

Xu Yang and the other three exchanged glances and followed.

"Hoho~"

"Boom!"

Lin Yao smashed a zombie's head with a single punch and happily pried out the crystal core with an iron rod.

"Hehehe, this crystal core is really beautiful, and it's even a golden superpower crystal core. It's perfect for the boss."

"Shhhhh!"

"Hoohoho!"

Li Xiang's wind blade tornado was also incredibly powerful. He stood half a meter in the air, engulfing all the zombies within three meters of him. Soon, the zombies' bodies were shredded and scattered, leaving only a small pile of crystal cores on the ground.

"Wind-based abilities are pretty good. Once he levels up, he can soar into the sky and become a true aerial acrobat," Hongtang said with some envy.

[Host, your spatial teleportation can actually also achieve flight.]

"Oh, little sister, is what you're saying true? Tell me more." Hongtang's eyes lit up immediately, and she didn't even feel the crystal core was so appealing anymore.

Sister: "..." She shouldn't have said anything.

Although she knew that higher-level spatial transfer could enable flight, the specific methods were not recorded in the subsystem, so her sister successfully muted herself.

Hongtang didn't mind. Ever since her younger sister was abandoned by the "main system," it would fall silent whenever it encountered unfamiliar content.

But knowing that space can also allow me to fly is enough. I just need to use it more and practice more in the future.

"Captain, watch out behind you!"

Despite being completely defenseless, Liu Xinnan held a gun in one hand and a knife in the other, constantly warning the group of danger from behind.

Seeing a zombie about to attack Xu Yang, she screamed in panic and pulled the trigger of her pistol, but the bullet missed and embedded itself in the wall.

"Waaah~ Captain!" Liu Xinnan cried out anxiously as the zombie's long black claws reached for Xu Yang's back.

"Clang! Sizzle!" A series of ear-piercing metallic clanging sounds rang out.

Following the sound, Hongtang looked up and saw sparks flying from the spot on Xu Yang's back where the zombie had scratched him, with the zombie's long fingernails shattered on the ground.

His body was as if it were coated with a layer of metal armor, making him indestructible.

Xu Yang turned around and extended his finger. A row of metal shuttles flew out quickly, instantly piercing the heads of several zombies behind him.

He then imbued the large sword in his hand with his metal-based supernatural power and slashed at the other zombies.

"So handsome, so handsome! Captain is so handsome!" Liu Xinnan wiped away her tears, laughing and crying at the same time, and walked up to the zombie whose head had been blown off to take the crystal core.

This was the first time Hongtang had ever seen other people with superpowers use their abilities up close. She was both amazed and impressed; each ability was powerful and had many uses.

Perhaps she could learn some techniques by "studying" how other superhumans fight?

Hmm, that's a great idea.

"Alright, the zombies around here have all been cleared out. The psychiatric surgery department is just ahead. Let's hurry over there, but we still need to be careful."

The four gathered around Hongtang. Xu Yang took a handful of crystal cores from Liu Xinnan. They were all colored supernatural energy crystal cores, numbering more than a dozen.

“Hongtang, although these crystal cores are not of high grade, they are all supernatural ability crystal cores. Consider this your reward for telling us about the uses of crystal cores and how to improve supernatural ability levels tonight. Please accept them.” Xu Yang’s tone was sincere and his facial expression was genuine. The other three also looked at her with starry eyes, as if they would force them on her if she didn’t agree.

"Alright, then I'll accept it. We're even now."

Seeing that Hongtang accepted it generously, Xu Yang breathed a sigh of relief. Otherwise, he would have owed her a huge favor and wouldn't know how to repay it in the future.

The big, clumsy Lin Yao led the way, with Li Xiang, Liu Xinnan, and Hong Tang in the middle, and Xu Yang bringing up the rear. Soon, the group arrived at a double fire door.

"The psychiatric ward is inside, but the door is blocked and can't be opened." Strongman Lin Yao tried several times but couldn't push the door open, leaving only a few dented fist marks on the surface of the door.

"I'll try."

Xu Yang placed his hand on the door, and soon a hole was melted in the door, revealing a thick layer of soil inside.

"It seems that an earth-type ability user has blocked the door," Li Xiang said, tapping his fingers on the surrounding walls again.
