Gray air is relatively light and is usually associated with bad luck and misfortune.

If someone goes into the river and comes into contact with the water, or drinks the water from the river, they may become unlucky, but the condition may not be serious.

But these are not the only points.

The point is that the river was fine yesterday, but it has changed today, and there is a problem with the water in the entire river.

Lin Xi's gaze involuntarily followed the upper reaches of the river.

Unfortunately, the river was quite winding, and she could only see that the farthest part of the river was flowing from the side of the mountain.

As for where the source of the river was, it was blocked by the mountain, so she had no idea.

"Xi, what are you looking at?"

Xu Jing took two steps forward and found that Lin Xi seemed to have stopped, so she immediately asked her what was going on.

Lin Xi withdrew his gaze and looked towards the lower reaches of the river.

The place where I met Professor Huang and his friends yesterday was right next to the river.

According to yesterday's observations, the villagers should not have gone into the river, but she was not sure whether outsiders like Professor Huang had come into contact with the river water.

If I had touched the river before today, it wouldn't be a problem.

If you come into contact with the river water after gray gas comes out, you may be in trouble.

Thinking of this, Lin Xi couldn't help but quicken his pace forward, intending to tell Professor Huang and the others to let everyone pay attention.

While talking, she did not forget to explain to Xu Jing what she had just discovered.

When Xu Jing heard this, she immediately widened her eyes and looked into the river.

Unfortunately, in her eyes, the river water was still clear and transparent, and there was no trace of the "gray air" that Lin Xi mentioned.

Although she couldn't see, she didn't doubt what Lin Xi said at all.

"Yes, yes, we have to go and tell the teacher right away. If anyone gets wet in the river, it will be troublesome."

Although from Lin Xi's tone, the danger of the river water is not that great at the moment, since they are all classmates and teachers, she still hopes that everyone can get along smoothly if they can avoid any trouble.

The two of them arrived at the meeting point quickly, and when they arrived, some classmates who lived nearby were already there.

As for the teaching team, only Mr. Xu, the team leader from yesterday, was left. Professor Huang and other teachers who were responsible for guiding them had not arrived yet.

Fortunately, Lin Xi was a third-year student at Jiangnan University. Almost all the faculty members on campus had heard of Lin Xi and knew her background, so Lin Xi did not hesitate too much and immediately went to Teacher Xu to tell her about the situation of the river water.

When Teacher Xu heard this, his expression immediately became serious.

Not only did she know Lin Xi, she also introduced Lin Xi to her relatives. In the end, the problem that her relatives had tried to solve with many people was easily solved by Lin Xi.

Since then, Teacher Xu has become even more convinced of Lin Xi's abilities.

"Okay, once everyone is done, I'll tell everyone not to go into the river and play in the water."

I told everyone that there was an unclean smell in the river water. Teacher Xu didn't know how to start, after all, she was still a teacher.

Moreover, not all students believe in metaphysics. There might even be atheists. She might object to what she said, or secretly file a complaint or something.

Teacher Xu didn't want to take such a risk.

Of course, she couldn't really ignore the safety of her students, so she could only try her best to remind them.

If students still insist on touching the river water after she has reminded them, then she really has no choice.

After all the students arrived, Teacher Xu gave everyone some instructions about the excuse he had just found.

She first warned everyone not to go into the river without permission, citing safety as a reason. She also said that the river water was a very important water source for the village, and that no one was allowed to touch it, so as not to pollute the water source.

Repeating it twice in a row can be regarded as highlighting the importance of this matter.

Teacher Xu looked at the expressions of the other students in the classroom and found that they must have taken his words to heart, so he nodded.

After a while, the team of instructors arrived. Professor Huang and others said a few brief words and then took the students to the archaeological base.

Although the archaeological base is located in the same village, it is still some distance away from the village's housing cluster, and it takes about fifteen minutes to walk there.

Because the archaeological base here was newly developed, the facilities and equipment are not as good as those of previous archaeological internship bases, and the roads under your feet are still the most primitive dirt roads.

Such an environment is undoubtedly a novel and unique experience for students who are experiencing real archaeology for the first time. No one complained about the rugged and difficult road along the way. Instead, they felt that this was the archaeology they imagined!
