Ruan Tian's electric tricycle has an invincible defensive time; within two hours, no zombie can break through this defensive line.

But two hours later, it will be the end of humanity.

"We must take precautions against all possible accidents within these two hours and devise solutions, otherwise things will be dangerous in two hours!"

When Ruan Tian said this, her expression was very serious, completely unlike her usual lively and cheerful demeanor.

After spending time with her, the others had come to understand Ruan Tian's personality to some extent, and seeing her like this, they also became nervous.

"Ruan Tian, ​​isn't your defense duration invincible?"

Some survivors still clung to the hope that Ruan Tian's defense duration was invincible.

If she were truly invincible, Ruan Tian would have already crossed her legs, enjoying her delicious food while watching these zombie mermaids writhe in powerless rage before her.

"It can only last for two hours, not a minute more. Stop clinging to useless fantasies. Instead of praying to God, you should think more about the next steps."

Ruan Tian's words of cold water dampened everyone's spirits.

Pence couldn't help but complain in the crowd, "I thought your superpowers were invincible, but it turns out they're just so-so."

Upon hearing this, Ruan Ruan abandoned her usual amiable demeanor, turned around and stared directly at Pence, who was still about to speak, and bluntly retorted:

"You say my superpowers are average? Then what are your superpowers? If it weren't for my electric tricycle, the zombies would have eaten you first!"

If you're so capable, why don't you take on all these zombies for me? And it was your mistake not to keep an eye on Lu Xuexue; she's carrying your child.

"I could have avoided saving any of you, and I could have even kicked you out. You really think you're so great?"

Ruan Tian's sudden aggression made Peng Si forget to refute for a moment, and he looked at Ruan Tian with a livid face.

She instinctively wanted to say something in rebuttal, but the words were already on the tip of her tongue when Ye Mofeng suddenly shot her a sharp glare.

Gu Yi smiled faintly at Peng Si. Although his smile was gentle, it turned into murderous intent in Peng Si's eyes.

"..."

With no other option, Pence had to swallow the profanity that was about to escape his lips.

Ruan Tian couldn't leave the protection zone of the electric tricycle, so she took Xiaobai out and let Xiaobai eat the crystal cores in big gulps.

"Come on, Little White, breathe will-o'-the-wisp!"

Xiao Bai swallowed the crystal core in his throat with difficulty and used Ghost Fire on the zombie in front of him.

Logically speaking, Xiaobai's abilities are very strong, and this kind of will-o'-the-wisp is an absolutely lethal weapon against zombies.

To Ruan Tian's utter surprise, these zombies didn't drop any crystal cores!

"How is this possible! The crystal core isn't falling off?"

Ruan Tian rubbed her eyes, thinking she was hallucinating, but looking at the empty ground, she immediately realized...

That's just how it is; the zombies killed by the will-o'-the-wisp didn't drop any crystal cores!

Ye Mofeng observed more closely and quickly noticed something amiss. He said to Ruan Tian:

"It's not that the crystal cores aren't falling off, but rather that after Little White levels up, the power of the ghost fire becomes stronger. The first-tier crystal cores can't withstand the power of the ghost fire and are burned away directly."

Upon hearing this, Ruan Tian's heart shattered completely!

The reason she was able to live so comfortably before was because of Xiaobai's ghost fire, which allowed her to kill zombies while simultaneously using their crystal cores, creating a perpetual motion machine that could loop indefinitely.

Now look what's happened! We thought that after Xiaobai leveled up, they would become stronger.

Unexpectedly, instead of being improved, the bug could no longer be exploited.

Ye Mofeng noticed the change in Ruan Tian's mood. He reached out and patted Ruan Tian's shoulder, saying softly:

"It's alright. There are gains and losses. It's good that Xiaobai is like this now. At least the power of the flames has increased."

Ruan Tian quickly regained her spirits. At least the electric tricycle could be upgraded with first-order crystal cores. As long as she could upgrade continuously, why would she have to worry about not finding enough second-order crystal cores?

"You're right! It's impossible to have it all!"

Ruan Tian rubbed her hands together, eager to get started. She reached out and gently patted Xiao Bai's head twice, soothingly saying:

"Go for it, Xiaobai! Don't be disappointed, you're the best in Mommy's heart!"

With Ruan Tian's comfort, Xiao Bai cheered up again, and his speed in consuming crystal cores increased.

Ruan Tian felt relieved. While fighting off the zombies, she watched as the mermaids mixed in with the zombie horde drew closer and closer to her...

I got goosebumps.

These mermaids look absolutely disgusting!

From a distance, it didn't seem like much, but when the mermaids got closer, Ruan Tian observed their scales up close!

Especially the pustules under the fish scales that looked like they were about to burst made Ruan Tian feel physically uncomfortable, and she almost threw up her dinner from the night before!

Although the electric tricycle does have an invisible protective shield, that doesn't mean Ruan Tian can accept that the fluid from these mermaids' pustules would spray directly onto the protective shield after they burst.

Ruan Tian took a deep breath and urged Xiao Bai to increase the speed at which it spits fireballs!

"This can't go on. I don't have many crystal cores left, and I definitely won't last two hours."

Upon hearing this, Ye Mofeng took out all the crystal cores he had and placed them on Ruan Tian. Then, he turned to look at the others and said:

"If anyone has any crystal cores left, please give them to Ruan Tian."

This is a matter of their survival.

Even the most selfish person, faced with so many mermaids and zombies, would be compelled by a strong will to survive to hand over most of their crystal cores.

With the support of these crystal cores, Xiaobai's subsequent development issues have been largely resolved.

Ruan Tian felt much relieved, but as the first mermaid finally got closer, her heart, which had finally calmed down, started racing again!

"What should we do? I don't know if it's just my imagination, but this mermaid looks really weird."

Pence rolled his eyes at the sky. He was extremely annoyed with Ruan Tian right now, and after hearing Ruan Tian's complaints, he spoke up directly:

"Can you stop talking nonsense? Do these mermaids really have such terrifying strength? I think they're just ordinary fish, at most with a unique appearance."

I don't know why you are so afraid of them, especially Ruan Tian. You have such powerful abilities, both offensively and defensively, and you even took so many of our crystal cores.

"If you don't take care of these pathetic mermaids, how will you repay us?"

Pence never expected that, as soon as he finished speaking, the seemingly "weak" mermaid would jump up from the ground!

Its legs are all muscles, and it can easily jump over a two-meter fence after jumping off the ground!

It landed right in front of Pence!
