With most of the zombies in the area already killed by Pei Yijun and his group, their journey back to the lecture hall was smooth.
Tailing them at a slow pace, Jiao Lizhi stops to examine the heads of the dead zombies. Using her wooden stick, she poked and stirred the charred brains, searching for crystal cores.
Some of the zombies' brains were burned by Pei Yijun's thunder-type ability and turned into a crisp, black charcoal. With just a light thrust of her wooden stick, the brains crumbled into blackened dust.
If there was a crystal core hidden within, it would remain intact and would glisten under the sunlight. Unfortunately, she found none so far.
At this moment, Jiao Lizhi was like a hardworking honey bee.
She continued her tedious task of poking and stirring the zombie's brain until her arm ached. Yet, out of countless zombies, she found only a level-one blue crystal core with a size no larger than her pinky nail.
Letting out a sigh, she examined the small crystal core. Its faint glow shimmering under the sunlight like a luminous pearl. Despite her frustration, she carefully stored the crystal core in her space.
Unbeknownst to her, the moment she stored the crystal core in her space, something unexpected happened.
Inside her space, the blue crystal core suddenly crumbled into dust, and the energy it stored floated in the air momentarily before being absorbed by the pond.
As the energy disappeared, the hole at the bottom of the pond released a surge of water.
Although the pond was already filled to the brim, the water continued gushing out without a hint of stopping. Strangely, it never overflowed, and the water level remained constant.
Outside the space, Jiao Lizhi finally finished checking the zombies' brains and found three more transparent crystal cores.
She wiped the sweat from her forehead with a smile. She looked at the lecture hall building for a moment before turning around. If nothing unexpected happens, this group of people should leave the university in one or two days.
Rather than waiting with a group of selfish people, she better find a safe place near the university entrance. She still had a fever and needed to rest to recover. If her fever kept dragging on, she didn't know what would happen to her already weak body.
If she recalled correctly, there was a small post for the security guard to stay in. Although the area was small, the post had iron doors and window bars, which made it safer than other places.
After making up her mind, she quickly ran toward the main gate.
Thirty minutes later, she arrived at the guard post and saw a zombie inside. The zombie had been walking aimlessly, but as she approached, it suddenly turned around and rushed toward the window.
"Roar!" it let out a roar while reaching out its rotten hands toward her through the window bars.
Looking at the zombie's sharp teeth and rotten face, Jiao Lizhi took out a boning knife from her space. She looked at the door and noticed it opened outward. Since that was the case, she couldn't use it to push the zombie back like before.
She thought for a while and an idea flashed in her mind.
Since she was able to produce more water in this life, maybe she could create a water blade to deal with the zombie. After all, the limitation for an auxiliary-type ability user wasn't a weaker ability but the limited energy to control it.
After making up her mind, she focused her energy on her palm and waved her hand.
In less than a second, a crescent-shaped water blade with a diameter of around 15 centimeters flew toward the zombie. The water blade was as thin as paper and flew between the window bars at a fast speed.
When she saw how small and thin the water blade was, Jiao Lizhi felt disappointed in her heart.
In her previous life, her water blade had reached more than 2 meters in diameter and 2 centimeters in thickness during her peak. She could kill a group of zombies in one move. Compared to her current water blade, the level was too far behind.
But before she could let out a sigh, she saw the thin water blade fly past the zombie's head and hit the wall with a loud sound.
CRACK!
Jiao Lizhi's eyes widened in shock as she saw the zombie's face split in half. Even the wall was left with a deep crack due to her attack. What's more surprising was that her water blade stayed in shape and did not turn into water as it stuck inside the wall.
The next second, the zombie fell to the ground with a thud.
Feeling the energy connection between her and the water blade, her heart was beating fast. With a flick of her hand, the water blade flew back to her and floated above her palm.
As she absorbed the energy back into her body, the water blade turned into water with a splash. She could feel that the energy she absorbed was around 30% of what she had used to create the water blade and control it.
She looked at her hands in a daze and muttered, "When did I get this ability?"
