We agreed to be a tour guide, how did it become the law of nature?

"It's okay, he just fainted for a short time. As long as he stays away from the smoke produced by the spirit phenol incense, he should be able to wake up after a while."

Shen Fei carried Ying on his back and continued, "Let's continue on our journey. There should be a place to rest when we reach Huachengguo."

Huachengguo was originally a temporary resting place built by Xumi scholars, and is now a place where forest rangers are stationed.

After walking for a while, Shen Fei and his friends saw another person.

After talking, he found out that the other party was a forest ranger, so he followed him to Huacheng Castle.

"Kole, where is your master?" the forest ranger leading Shen Fei and his group shouted towards a tree house.

Soon, a petite girl with light green hair who looked young came out.

"What happened?" She looked at the girl on Shen Fei's back, "My master hasn't come back yet."

"This is a problem. The girl inhaled the smoke of phenol and passed out for some reason," said the ranger.

"Ah?! Well, then you wait a moment, I will go find my master right away." Hearing this, Ke Lai also became a little anxious.

Shen Fei stopped the other party and said, "Don't worry, my companion is fine. We just need to find a place for her to rest."

Then he looked at the other ranger and said, "Thank you for leading the way for us."

"The incense of phenol is something that scholars use to calm themselves down. Some people may have special physiques and will have adverse reactions after inhaling it, but it shouldn't be a big problem."

The man nodded, then looked at Ke Lai: "Then I'll leave first. Remember to tell your master when he comes back."

"Please follow me." Cole quickly invited Shen Fei and others into the tree house.

The tree house is not big. In addition to a simple wooden bed, there is also a medicine table and a wooden table. There are a lot of sundries piled on the wooden table, and plants are being ground on the medicine table.

Ke Lai pointed to the wooden bed and said, "Put her here first."

The space in the tree house was a bit small, so Shen Fei put Ying on the bed and then walked out.

"I hope Ying is okay?" Paimon was a little nervous.

Shen Fei said: "Don't worry, he is just temporarily unconscious."

"Ying's strength is not weak, why did she pass out after just inhaling a little smoke?" Wendy was a little puzzled.

Raiden Zhenye was puzzled and said, "Yeah, logically speaking, if there is any problem with the smoke, I should be the first one to collapse."

"There is nothing wrong with the fragrance of phenol. The special thing is that Ying's elemental perception is particularly strong. She may have sensed something." Shen Fei said.

As they were chatting, a dog-eared man with a bow and arrow and a medicine bag on his shoulder walked over from a distance.

"Who are you?" Tinari asked.

"Hello, I am Shen Fei, the leader of the Teyvat tour group, and these are my members." Shen Fei stood up and introduced several people around him to the other party.

Hearing the noise, Kelai ran out of the tree house, "Master Tinari, you are back. There is a patient here."

After learning what happened, Tinari said as he walked inside: "I see, but you don't have to worry, the spirit phenol fragrance usually doesn't do any harm."

"Oh, by the way, my name is Tinari, and I'm the ranger of Huachengguo."

Ke Lai also reacted and said quickly: "Hello, um... my name is Ke Lai, and I'm a trainee forest ranger."

So Shen Fei introduced himself and the people around him again.

After some examination, Tinari confirmed that Ying was fine and just needed to rest for a while and wait for her to wake up naturally.

The tree house was too crowded, so Shen Fei took the tables and chairs outside, took out a lot of tea and snacks, and invited Tinari and Cole to enjoy them together.

During this period, Tinari talked about many interesting things he encountered during the forest patrol, and Shen Fei and his friends also introduced what they saw and heard during the journey. The atmosphere was very harmonious.

"Captain Shen Fei, is Amber okay?" Cole, who was eating Inazuma's specialty: Hinasakura Mochi, suddenly asked.

"Scout Knight Amber, how do you know her?" Paimon was a little confused at first, then he suddenly realized: "Ah, it turns out to be you. I didn't react at first to the good friend Cole that Amber mentioned."

"Don't worry, Cole, Amber is fine now." Shen Fei said.

A trace of reminiscence appeared on Ke Lai's face. "Come to think of it, I haven't seen her for a long time. We have only been communicating through letters."

"I can see that you really want to see her. Why don't you go to Mondstadt for fun? Is the ranger's vacation very short?" Lei Dianzhen asked.

Cole shook his head and denied: "No, it's not like that..."

"Kole..." Tinari put down his teacup and sighed, "She suffers from a rare disease and can't travel far."

Shen Fei said: "It's the Demonic Scale Disease, right?"

Tinari nodded, and Cole fell silent, his expression slightly gloomy.

"Shen Fei, what is the Demonic Scale Disease?" Lei Dianzhen asked.

"This is a disease unique to Xumi. Black scales will grow on the patient's body."

Shen Fei said slowly, "At first, you will just feel some numbness on the affected skin, then you may experience loss of strength and numbness in your limbs, until you can no longer control your body."

Tinari sighed, "It's not just Kelai. There are many people in Xumi who suffer from the Demonic Scale Disease. I have studied it for many years, but I have only found a way to temporarily suppress the disease, but I can't completely cure it."

"Because the root of the problem is not in humans." Shen Fei looked at the other party, "You can think about why there is no such disease in other places."

"Could it be because of the dead zone?" Tinari quickly found the key point and frowned slightly, "But there is no way to completely solve the dead zone at present. We can only deal with it in time when it is discovered."

"Moreover, the frequency of the dead zone appearing has increased over the years, and Cole's condition has also worsened. The two seem to be related."

"What is the Death Zone?" Paimon asked puzzledly.

Shen Fei explained: "The dead zone is an area formed after being eroded by an ominous force. It will not only cause plants to wither, but also take the lives of animals and humans. Only those who can control the elemental force can resist the erosion of the dead zone for a certain period of time."

"Why would such a thing appear on Xumi?" Lei Dian was really puzzled.

Zhongli pondered and said, "When something happens, there must be a root cause. If the Demonic Scale Disease is related to the existence of the Dead Zone, perhaps resolving the problem of the Dead Zone can completely cure the Demonic Scale Disease."

"The root cause?" Tinari recalled carefully and said, "After my research, the dead zone did appear suddenly without any signs. The reason for its formation is not clear yet."

"But you are foreign travelers. You may have a different opinion next time you see me."
