Reborn in that autumn

"I know," Ye Qiu replied.

"There really is a river!" Ye Qiu was surprised.

He asked Ao Shijie in the space: "Uncle Aoxue, why is there a river underground!"

Ao Shijie took one look and knew what it was, and said to Ye Qiu: "This is not just a river, this is an underground river."

"Underground river! What is an underground river?" Ye Qiu asked Ao Shijie in the space.

Ao Shijie replied: "Underground rivers, in your current terms, underground rivers, also called "undercurrents", are water flows with the main characteristics of rivers in caves and underground channels formed in large areas of limestone due to karstification. Underground rivers often flow beneath the surface of the earth or in mountain caves, making them difficult to detect."

"The power of nature is really amazing. It has created many miraculous wonders that are breathtaking. Underwater River is one of them."

"Underground rivers are mainly developed in limestone areas, and local people call them "yin rivers." As the name suggests, they are "invisible rivers" to ordinary people under normal conditions."

"But the "underground river" is not only "dark", it is buried tens of meters or even hundreds of meters deep underground, and it is also very dangerous. It is very different from the daily "river""

"The underground river itself has a certain length, and there are supporting underground river tributaries." The ground is developed into linear, water depressions-sinkholes-shafts and so on."

“Through their connection with the underground, long-term rainfall and surface water infiltration form long-term underground runoff in underground rivers.”

"Special types of cave insects and aquatic creatures can even be found in some mountainous underground river systems. It is worth mentioning that there are unique fish," Ao Shijie said in particular.

Ye Qiu happened to have a question in his mind, and obviously noticed it, and asked: "What is a unique fish?"

Ao Shijie replied: "It can eat people and bite people, and it may even be poisonous. Maybe there is something in this underground river."

Ye Qiu asked curiously: "How do you know so much? It doesn't look like you learned it in ancient times."

Ao Shijie replied: "Didn't I just go to the library in your space? I was looking for a mechanism on how to cross the quicksand. I saw it by the way. I didn't expect to explain it to you now."

"You can learn it now and sell it now, but it saves trouble and saves me from watching. What else do you know?" Ye Qiu asked Ao Shijie again.

"A fish jumped out of the water," Li Zichen shouted from behind.

Ye Qiu heard this and took Ao Shijie in the space to look at the fish jumping out of the underground river.

"It's it, and it's so big. How can it be impossible? It's too big!" Ao Shijie exclaimed.

"What is it! Are you screaming like this? Is it something scary? Isn't it just a big fish?" Ye Qiu saw Ao Shijie's surprised expression and asked.

Li Zichen outside the space also exclaimed: "What a big fish."

Reacting quickly, he pulled Ye Qiu back and asked Ye Ran and others to walk back.

Li Zichen didn't stop until he retreated to a place where Li Zichen felt safe.

He turned Ye Qiu's body around and asked in a worried tone: "Ye Qiu, how are you? Are you scared? I thought there was no danger. If I had known, I wouldn't have let you go up to see. What's wrong? Talk. , are you scared?"

Ye Qiu raised his head and met Li Zichen's concerned eyes, and replied with a reassuring smile: "I'm not scared, don't worry, I'm just surprised, not scared at all."
