Seeing this, Yu Bai stopped disturbing the warmth that was quietly growing in the ward.

She turned around and walked out the door with the book in her arms, walked briskly across the corridor, and headed straight into the bathroom at the end of the hospital.

The door locked with a "click", blocking out the noise from the outside world.

Yu Bai took a deep breath and disappeared from the spot in an instant.

The space still has the familiar tranquility and freshness.

She wanted to find a corner to rest for a while and get rid of the fatigue that had accumulated over the past few days.

But before he could sit down, he heard a muffled "bang" coming from the west gate.

Immediately afterwards, a tall figure pushed the door open and walked in - Han Yi was here.

He saw Yu Bai at a glance, and immediately smiled heartily:

"Wow, my luck is so good! I run into you every time I enter this space!"

As he spoke, he strode to the counter and placed the two metal boxes in his hands heavily on the table.

"Let me show you something good!" Han Yi was beaming with joy and opened the lid of the box skillfully.

I saw two boxes filled to the brim with crystal cores, each of which had a light pink sheen and was as tempting as a peeled lychee.

Compared with the previous crystal cores, the color of this batch of crystal cores has clearly been upgraded by more than one level!

"Wow!" Yu Bai couldn't help but exclaim, "Have these crystal cores been upgraded?"

"you do not say."

Han Yi patted the edge of the box and looked in a very good mood.

"The temperature has suddenly risen in the last two days in the apocalypse, it's over ten degrees Celsius. We have to move to a new location and build a new base."

"Well, to ensure a smooth journey, I led the team to clear out all the zombies lingering around."

He said this with a slightly lowered tone:

"But once the temperature rose, the zombies evolved at an insane rate. A few of them nearly killed us. Luckily, after everyone absorbed the evolved crystal cores, their strength increased rapidly, so we managed to hold on."

"The pink one is level two, right?"

Yu Bai stretched out his hand and picked up one of them. He felt the palm of his hand was slightly cool and soft. Before he could take a closer look, a dense, gentle, yet surging and powerful energy flowed into his body from his fingertips!

The next second, she felt as if a spring breeze had washed over her, cleansing her from bone marrow to her blood. All fatigue, anxiety, and distracting thoughts melted away in that moment, leaving only every cell in her body leaping for joy, enveloped and lifted by an invisible force.

Pure!

powerful!

Even with a touch of intoxicating sweetness!

She suddenly opened her eyes, her eyes full of disbelief. She could absorb energy!

You know, when Han Yi gave her the crystal core for the first time, she also tried it. When her fingertips touched it, it was like a stone falling into water, without any reaction at all.

Even my mother, Zhou Fengxia, who had a special physique, could only feel an extremely weak breath. It was more like passive nourishment rather than active absorption.

"What's going on?" Yu Bai looked at Han Yi, his voice trembling unnoticed. "I've touched the crystal core before... and there was no reaction."

Han Yi was also stunned, then scratched his head and guessed uncertainly: "Maybe it's... because of the evolution of the crystal core?"

He explained, "In the apocalypse, whoever develops superpowers doesn't first experience a high fever or severe pain, and walk through the gates of hell?"

"You're suddenly able to absorb the second-level crystal core without any pain or illness... This can only be attributed to the fact that the energy of the second-level crystal core is more pure and larger, or... you have a special physique?"

Han Yi couldn't explain it either. After all, this kind of direct absorption and upgrade was unheard of.

Who cares what the reason is!

Yu Bai was too lazy to delve into it, as long as the result was good!

She closed her eyes and carefully felt the warm yet explosive energy flowing slowly through her body, cleansing her limbs and bones.

Unprecedented lightness! Unprecedented comfort!

It was as if the whole person was reborn, and the fatigue and mental stress accumulated from days of running around disappeared without a trace.

All that's left is a pure feeling of comfort that makes you want to roar to the sky!

"Very good……"

Yu Bai murmured softly, the corners of his mouth unable to help but rise.

She opened her eyes and looked at the two boxes full of pink crystal cores in front of her, and a warm feeling surged in her heart.

"Han Yi, this crystal core is too valuable. I can't take it for free." Yu Bai said seriously, "What do you need? Food? Water? Or something else?"

These two boxes of second-level crystal cores are definitely strategic materials that can greatly enhance the strength of a small base in the apocalypse!

Han Yi waved his hand and smiled brightly:

"Hey, why are you being so polite to me?"

"The supplies you gave us earlier are enough to sustain our base for a long time. Besides, we're going to migrate soon, and it's inconvenient to carry too many things."

He paused, his eyes filled with anticipation:

"Once we find a new place and settle down, I'll come back to see you. I'll need your help then!"

"Okay." Yu Bai nodded decisively, "It's a deal."

"Then I'll be leaving first. There's still a lot of things to do at the base."

After Han Yi finished speaking, he waved to Yu Bai and disappeared from the spot.

At the same time, at the doomsday base outside the west gate.

The makeshift shantytown was bustling with activity.

The men were shouting as they packed up the last of the useful supplies they had collected and loaded them onto modified trucks.

On the other side, Zheng Sisi was busy with a group of women around several makeshift stoves.

The rich aroma of meat mixed with the mellow smell of the sauce filled the air, making the men working nearby unable to help but twitch their noses and swallow their saliva.

They are making meat sauce.

"Sister Sisi, you are still smart!"
