Before Jiang Wan could finish speaking, a sticky thing jumped out of the water pipe. It was probably struggling and jumping around on the ground because it had lost water.

It looked like a fish, but it was clearly not a normal fish. When its head was facing them, it must have smelled the fresh flesh and blood of humans. It instantly opened its blood-red mouth, revealing a mouthful of sharp teeth.

Jiang Wan and Mi Mang were both composed people, but even they were startled and took a few steps back, screaming, "Zombie!"

This zombie fish completely lost the aquatic characteristics of normal fish, and suddenly leaped on the ground, heading straight for Jiang Wan and the others.

Jiang Wan raised her whip and lashed it down, instantly striking the zombie fish and splitting it in two.

But it didn't die; even though it was broken in two, it still bravely continued to fight towards her.

This time, Jiang Wan was prepared. When she swung the vine whip, she aimed directly at the zombie fish's head, smashing it to pieces.

The zombie fish finally stopped jumping around, and the water pipe returned to normal operation.

There weren't many people around, and the patrolling guards weren't there. Jiang Wan and Mi Mang were still shaken and terrified.

Mi Mang couldn't help but pat his chest and say, "I never expected there would be zombies in the underground river."

Jiang Wan was still shaken. She put away the rattan and stared intently at the water pipe to prevent another zombie fish from emerging from it.

"I need to remind Cheng Zhen later that the zombie fish in the underground river come in all sizes. If a small zombie fish pops out and they don't notice it for a while, then the humans will be in danger."

Mi Mang nodded in agreement and helped her keep an eye on the water pipe outlet.

If you see any small fish or other creatures emerge, kill them immediately.

Although the sun had already set, the weather was still very hot, and the surrounding heat was making people feel very uncomfortable. She looked at the gushing water flowing from the tap and couldn't help but swallow.

The sound was somewhat abrupt, but Jiang Wan, standing next to her, could hear it clearly.

She suddenly turned to look at Mi Mang, her eyes sharp and her expression stern.

Startled by those eyes, Mi Mang took a step back. "Jiang... Jiang Wan, what's wrong?"

Jiang Wan suddenly asked, "If the creatures in the underground river are all zombies, is the water drinkable?"

"Of course not!" Mi Mang answered instinctively, her face turning deathly pale as she finished speaking.

The well for groundwater has been dug for more than ten days, and the wellhead has not been sealed. Many people have been going to the well to fetch water for drinking these days.

Some people will bring it back and boil it, but others can't stand the heat and drink it directly, and use it to wash their hair, face and body.

"Hurry, let's go see!"

Jiang Wan shut off the valve and pulled Mi Mang along as they ran toward the well. On the way, they saw the patrolling city guards and quickly instructed them, "Go and call your city lord. Tell him I have something urgent to discuss and that he should go to the well!"

Seeing their urgent situation, the patrolling city guards didn't dare to delay and ran to find Cheng Zhen.

Upon hearing that Jiang Wan urgently needed to see him, Cheng Zhen immediately activated his teleportation ability, so he arrived at the wellhead earlier than Jiang Wan and Mi Mang.

People were drawing water from the well. Some were filling buckets to boil the water before using it, while others were washing their faces and hair directly with the water because it was so hot.

Upon seeing this, Jiang Wan immediately shouted, "Put it down! Put all the water down! Don't move! You can't wash!"

"What's wrong? What happened?"

Cheng Zhen thought something had happened to her and rushed over to check on her out of concern.

Jiang Wan shoved him aside and pushed him toward the well, saying urgently, "Quickly seal the well opening and don't let them touch the water! There's something wrong with this water!"

Although Cheng Zhen didn't understand what had happened, he subconsciously chose to listen to her and immediately ordered people to seal the well.

The water that had already been drawn up was poured back down, but they were too late.

A bucket full of water was placed on the ground, and no one was around. Suddenly, it tipped over, spilling water all over the ground. A lively fish suddenly jumped up and bit the leg of the nearest person.

His jumping ability is truly amazing!

Jiang Wan was prepared; the moment it jumped, she lashed it away with her vine whip. "There are zombies in the water! Everyone, get out of here!"

Everyone around dispersed, leaving only Cheng Zhenjiang and the patrolling city guards.

The zombie fish was also killed by Cheng Zhen using his light-based ability, but looking at the corpse of the zombie fish, everyone felt very heavy-hearted.

Yu Fen and the others rushed over upon hearing the news: "Holy crap! How come there are zombies in the underground river?"

Cheng Zhen countered, "Why aren't there any zombies in the underground river?"

This is actually a misconception on their part. They take it for granted that underground rivers are safe places, but in reality, the whole world has become an oxygen-deprived apocalypse, so how could underground rivers be an exception?

Fish in the river die from lack of oxygen, and they will naturally become infected and turn into zombies.

"But we've been using water for over ten days, why is it only appearing now?"

Jiang Wan: "This isn't hard to explain. The underground river's basin is vast, and the well we dug is just one part of it. It's normal that there weren't any concentrated zombie fish here before. Once a zombie fish appears, it means that there will be a continuous stream of zombie fish appearing later. But that's not the most important thing..."

Cheng Zhen and the others were listening to her, and subconsciously asked, "What's the important thing?"

"The underground river water is unclean; there are zombie fish in it. We've been digging a well for over ten days, and many people have drunk the water from it," Jiang Wan warned.

"Damn it! Didn't we tell them not to drink the water in there?" Cheng Zhen's eyes flashed sharply as he glared around. "How many people drank it? Are you all out of your minds?"

"It's too hot. If there's water in front of you, everyone will want to drink or wash with it. It's no use blaming them. Instead of doing that, we should find out who drank the water as soon as possible and put them in centralized isolation for treatment."

She does have a "tree hole" night, but the last time she treated everyone to detoxification, she had already used up too much of her energy, and what she had left was not enough to support everyone's detoxification.

Therefore, it is necessary to gather those who drank the water together and detoxify them in a targeted manner.

Cheng Zhen was furious and ordered, "Go and call out everyone who has drunk or used the water."

Yu Fen took the order to call for help, while Cheng Zhen asked Jiang Wan, "How did you discover that there was something wrong with the water?"

"The potatoes in the forest have already sprouted. When we watered them, the mutated zombie fish blocked the water pipes."

Upon hearing this, Cheng Zhen instinctively looked her over and asked, "Are you alright?"

"It's alright, but this well isn't safe anymore. What are you planning to do?"

The well has a strong smell of living people, which will only attract more and more zombie fish. Once the zombie fish gather at the bottom of the well, they will probably have difficulty getting water in the future.

Cheng Zhen let out a heavy sigh: "There's no other way but to open up a mountain path."
