, the most beautiful gift given by nature.

"elder brother..."

"what?"

"It's so beautiful here...I really want to go to the hot springs..."

"Have you brought any clothes? Besides, this hot spring water can also glow, so maybe it is something. I heard in July that there is a kind of hot spring called radioactive hot spring."

"Well, brother, don't you want to go down and take a hot bath now?"

"...Who doesn't want to? It's so cold that I can hardly feel my hands and feet."

The fluorescent hot springs are indeed beautiful...and extremely exciting.

But the two of them were unsure of the situation, so they immediately turned back the same way.

The two people hurriedly went down the mountain. Suzu Sakakihara came to the vicinity of the camp very excitedly. She ran all the way and quickly opened the zipper of the tent, wanting to announce the news to the three people who were still chatting in the tent.

"I...I!...I-"

Inside the tent, Amami Qimingyue pulled up the quilt and looked at Sakakibara Suzu at the door with half-closed eyes. She said dissatisfiedly: "I suggest you, sister-chan, take a breath before speaking. Also, zip up the tent quickly. I don't know that it's minus ten degrees outside."

Spend?"

"I...I...I..." Suzu Sakakibara was wearing a heavy cycling suit, breathing heavily, and white mist kept spitting out violently with her breathing.

"Something happened to Lejun?" Tianhai Jiuliuli became confused and worried.

When Jiuliuli asked, Tianhai Zhixue also looked over with great concern.

"No...no such thing. I...my brother...he...he is fine."

Tianhai Qimingyue was even more speechless: "Then sister-chan, why are you in such a hurry? And quickly pull up the chain, otherwise the three people here will freeze to death tonight."

"Warm...warm...hot spring!"

"Hot springs? Sister-chan, are you hallucinating in your head? We haven't reached Lake Kussharo yet, and there are no hot spring hotels here."

"No, it's not...it's true! There is really a hot spring! Hurry! Put on your clothes and come out! Hurry over!"

...

Overjoyed to see Sakakibara Suzu, the two sisters Jiu Liuli and Qi Mingyue looked at each other, realized something was wrong, and quickly got dressed.

"Yuki! Yuki is getting up soon."

By the way, I also woke up Tianhai Zhixue.

Several people spent a few minutes putting on their thickest motorcycle riding clothes and quickly walked out of the tent.

It was still dark in the early hours of the morning, and the visibility was extremely low, but Nanami Nanami could see Sakakibara Raku standing in the woods on the right, holding a flashlight and shining his light on the people on this side of the tent.

"Sister-chan, it's best to tell the truth."

"What did I lie to you for?"

"This place doesn't look like a place with hot springs at all. First of all, we still have nearly two hundred kilometers to go. Secondly, we haven't reached Lake Kussharo yet. This area is not on the volcanic belt."

"Oh! It's true! It also glows!"

"Glowing?! Did you hit a radioactive hot spring?"

"Is there really such a hot spring?"

"Yes, why not? It is generally considered to be a very healthy hot spring." Tianhai Qimingyue pinched her chin, and after thinking about it carefully, she felt that something was wrong. "But the elements that generally contribute to the formation of radioactive hot springs are radon and thorium. These two

This element does not emit visible light."

Several people were talking while walking towards Sakakihara Raku's position.

"Sister-chan, tell me what color you met?"

"Light green, bright and shiny, very beautiful."

"Yinglu... There are some other radioactive elements that will emit light, but there are no natural hot springs with special ores nearby. Logically speaking, there shouldn't be such high radioactive elements."

Jiu Liuli and Yuki had already rushed to Sakakibara Raku. Sakakibara Suzu hurriedly dragged Amami Qimingyue forward, "Oh, oh, oh! Sister Qiyue, don't think so much, go over and take a look first, and then we'll talk!"

"...That's all it can do."

...

The five people followed the route they had just explored and braved the cold wind and snow to climb up the mountain again.

This distance is not that close, and the previous July's physical fitness would definitely not be good.

Raku Sakakihara was a little lucky that she had gone for some exercise by running and playing basketball before.

Once again we came to this small flat land of gravel with rugged boulders.

When the three of them came behind the boulder and saw the hot spring for the first time, they were as shocked as Sakakihara Raku and Sakakihara Suzu had been when they saw it...

Karst caves, luminous natural hot springs, and huge amounts of hot air rising upwards. Such a dreamlike scene actually appeared in the cold and snowy weather... Who could not love it?

There are still concerns about the hot springs emitting green light.

...

"How about July?"

Raku Sakakibara came to the squatting side of Nanami Nanami, who was carefully examining the composition of this natural hot spring.

"Smells of sulfur..."

"Should it be a sulfur hot spring or a hydrogen sulfide hot spring?"

"Yes." Tianhai Qimingyue nodded.

"Then why is it glowing green? It can't really be a radioactive hot spring."

"General radioactive hot springs are not harmful... Moreover, radon is colorless, tasteless and odorless. The smell of this hot spring is not strong, which means that the hot springs that make up this hot spring can only be hydrogen sulfide hot springs with mostly hydrogen sulfide..."

Tianhai Qimingyue raised her head and looked at the translucent hot spring water in front of her.

At the same time, she noticed that this hot spring was not only green, but also yellow, orange and other colors...

Tianhai Qimingyue stood up.

"July?"

"I see."

"What did Sister Qiu think of?"

"The stuff that makes up this color..."

Tianhai Qimingyue recalled seriously, "The substance that causes this hot spring to shine is probably a thing called oxalic acid bacteria. This kind of thing in hot springs usually emits orange, yellow, green, or some

Mixed colors. And will fluoresce at night and in low-light environments under certain specific conditions."

"Is it harmful?"

"Although oxalic acid itself is toxic to the human body, the dose must be diluted in such a large hot spring. In Hokkaido, many hotels use 'fluorescent hot springs' as a publicity stunt. This is normal."

Tianhai Jiuliuli approached, "That is to say..."

Tianhai Qimingyue gave a direct answer, "You can soak it."

"Okay...yes!"

As soon as Sakakihara Suzu heard the news, she jumped up and down with excitement and wanted to take off all her clothes right away.

"Yuki! Did you hear that, yuki? You can take a bath in the hot spring!!"

"Hmm... um..." Tianhai Zhixue was stunned by her shaking.

Liuli was also very happy after hearing this.

"Hurry up, hurry up! Without further ado, let's take a bath in the hot springs together!!"
