As if to make it more appropriate, the system's voice sounded in Xie Xuan's mind.

The current spore concentration detected is 65%.

[Health decreased by 5.]

But this passage has finally come to an end at this moment.

A white dot appeared out of nowhere in front of them and suddenly enlarged, swallowing up all three of them.

Xie Xuan subconsciously closed her eyes, and when she opened them again, she saw a vast expanse of white in front of her.

It was snowing, and the falling snowflakes landed on Xie Xuan, but Xie Xuan didn't feel cold at all.

She reached out and picked up a snowflake stuck to her clothes and crushed it, but found that it was not a snowflake at all, but small pieces of white powder similar to the volcanic ash that floated everywhere after a volcanic eruption.

"These are ashes." Xiao Yu suddenly said, "Do you smell it? The smell of decay."

Of course Xie Xuan smelled it. In this place covered with white ashes, the air was also filled with the pungent smell of decay, a characteristic of mushrooms.

"Where should we find the fungus strains now?" Xie Xuan asked.

Xiao Yu turned around and "looked" at Xie Xuan. He suddenly stretched out his hand and gently placed it on Xie Xuan's shoulder.

His movements were clean and neat, without the unnecessary fumbling movements of other blind people, as if he could still see the person standing in front of him.

"What...?" Before Xie Xuan could finish her words, she suddenly felt a sharp pain in her heart, and then her consciousness and vision went blank.

Xiao Yu supported Xie Xuan who had fallen down and carefully laid her flat on the ground.

"You don't have to do this." Xiao Yao frowned slightly, "I brought a shot of anesthetic."

Xiao Yu smiled gently, stood up and said, "Are you feeling sorry for her?"

He shook his head after he finished speaking. "That's true. After all, she was the only two girls among the ten people. After the other one died, who among us wouldn't love her the most?"

Xiao Yao didn't respond to this and asked in a stiff tone, "Why are you following Doctor Song?"

"You shouldn't use the word 'want'. We never have a choice, do we?"

Xiao Yu walked forward while speaking, "Doctor Song is now a big name in the organization. My ability is a perfect match for his current research topic. He specifically asked for me, so I couldn't refuse."

Xiao Yao's face darkened slightly, and he closed his eyes. "Sorry."

"No need to apologize." Xiao Yu didn't look back, "Come and give me a hand."

Xiao Yao walked forward to Xiao Yu's side, half-knelt down with him, and brushed away the thick ashes on the ground with his hands, revealing the blue mycelium underneath.

When the blue mycelium surged upwards and was about to attack, Xiao Yao put his palm on it, and flames immediately ignited on the blue mycelium.

The fire spread rapidly, but the place where they and Xie Xuan were lying was completely intact.

The mycelium twitched violently, as if trying to put out the flames on itself, but all this was destined to be in vain.

At this moment, Xiao Yu's hand reached into the burning mycelium. The flames perfectly avoided Xiao Yu's hand, jumping and burning more and more vigorously.

In the flames rising into the sky, Xiao Yu slowly pulled his hand out. In his palm, a ball of fluorescent blue mycelium was lying quietly on it.

This ball of mycelium neither withered nor showed any signs of infecting Xiao Yu. It nestled neatly in the palm of Xiao Yu's hand like a quail without any obstruction.

Xiao Yao didn't look at it any further. When he stood up, the flames that filled the entire space suddenly went out.

The bacteria were under control, the territory was beginning to collapse, and they had a little time to speak.

"Is this also one of Dr. Song's experimental subjects?"

Xiao Yu nodded and turned to walk towards Xie Xuan. "Yes, but there was a little accident along the way. The experimental subject controlled the infection process and became a mutant. However, this strain of bacteria is quite special, and Doctor Song specifically requested that it be recovered, so I had to do a little more."

Perhaps due to time constraints, Xiao Yu didn't wait for Xiao Yao to ask any more questions before continuing, "There were three test subjects in the performance hall at the same time. They were infected with the same bacterial strain. After I put Zhang Zheping into a near-death state, the bacteria in his body devoured him and the other two test subjects as well. I need to dispose of these two bodies as well."

Xiao Yao didn't need Xiao Yu to explain the reason in detail this time.

People from the Ecological Bureau's Accommodation Department showed up here. If the Ecological Bureau were to get the two bodies, it might cause trouble for Xiao Yu.

Xiao Yao has now been forced to become particularly good at post-processing work. "I know. I will help with it."

Xiao Yu had already stopped beside Xie Xuan. He half-knelt down and said, "One of the experimental subjects stabbed Xie Xuan before being eaten, so..."

Xiao Yu directly plucked off a piece of mycelium the size of a quail egg from the goose egg-sized ball of fungus and placed it on Xie Xuan's chest.

The domain had begun to collapse, but Xiao Yu and Xiao Yao were not in a hurry at all. They watched as a few strands of mycelium emitting flickering blue light trembled and spread out from Xie Xuan's chest.

The mycelium was obviously frightened by Xiao Yu, but the fragrance of its own kind was too tempting. After testing and confirming that neither Xiao Yu nor the quail egg-sized mycelium had any intention of attacking it, the blue mycelium suddenly stretched out a few strands of mycelium and pulled the quail egg over. It swallowed it whole in a few seconds and returned to its position on Xie Xuan's chest.

Xiao Yao's brows were slightly knitted from beginning to end. "What the hell is this?"

Xiao Yu stood up and casually put the remaining bacteria, which had re-formed into a ball, into the pocket of his white coat. "It's just a bacteria strain. It just coexists with humans differently. Even if it fails to parasitize, it won't become an infection and can still live to the end of its life."

He paused, his unfocused eyes fixed on Xie Xuan lying on the ground. "Xie Xuan's situation is a bit more special. The original bacteria in her body are still dormant, but once her own bacteria awaken, it's hard to say what will happen."

Xiao Yu chuckled softly, "After all, her situation is different from yours. Instead of worrying about her, you might as well worry more about yourself."

Xiao Yao also laughed, "I'll return this to you as well."

The domain finally collapsed completely at this moment, and the surrounding scene completely dissolved. The three of them were standing in the circular pool in the center of the stage that was used for the performance at the beginning, and Xie Xuan was lying right in the middle.

"I'm leaving first." Xiao Yu waved in Xiao Yao's direction like a person with normal vision and walked towards the stairs.

Xiao Yao stood on the withered mycelium and watched Xiao Yu's back disappear into the backstage. In the end, he didn't say a word.
