"I want to walk around the lake, where are you?" Yan Chong thought for a moment and said to Maxim.

"So too." Maxim nodded and took back the detection instruments and various potion bottles into the space equipment.

The two of them walked on the grass by the lake.

While walking, Yan Chong carefully observed the moon grass on the ground, and at the same time activated the [elemental vision] ability and paid attention to the distribution of elements inside.

[Elemental Vision] Strictly speaking, it is not a skill. Skills require mental power, physical strength, qi and other things to be activated.

Elemental vision is like a car's rearview mirror, which is there. When you pay attention, you will find that you have both front-view and rear-view vision. If you don't pay attention, you will still have a normal front-view vision.

It does not require the consumption of mental power, or the consumed mental power is indefinitely evident.

The withered yellow moon grass near the lake water almost has very light black elements inside, and even the moon grass, which is five or six meters away, has a little bit of it.

If Yan Chong hadn't observed it very carefully and meticulously, it would have been easy to ignore it.

"The black element should be a dark element." Yan Chong was a little suspicious, but he was not sure.

Because the color of an element depends on the cognition of the profession, not the color of the reflected light, it is directly perceived by mental power.

The general perception of earth, water, wind and fire is yellow, green, blue and red. Although black is likely to be a dark element, black also represents many situations such as depth, unknown, and unknown.

It can be said that if a professional has not been exposed to certain elements, it is possible that these elements are all black in his eyes.

"Devil card can absorb dark elements. Is it related to demons?" Yan Chong couldn't help but associate the two together.

However, the devil card is just called the devil, and it may not have anything to do with the real devil for half a cent.

Because it is just a card in the deck of the source, and there are cards called Angels in the deck.

The demon has not appeared on the continent for a long time, although related legends have been circulating, and the orcs have also obtained the blood of the demon through some strange means.

As professionals above the bronze level, their physical fitness was naturally much stronger than normal, and they quickly turned the entire Jingyue Lake around.

Along the way, they also met Linglingluoluodi Academy students, who were obviously here to do the task.

However, it is not necessarily the case that we investigate water pollution. There are some rare herbs by the lake, and many tasks are collected by collecting these herbs.

"Huh?" Yan Chong walked a few quick steps, squatted down, and carefully pulled out a green grass about fifteen centimeters long.

At first glance, it is no different from ordinary Moon grass, but if you look closely, there is a light blue line in the center of the leaf veins, which is a Moon grass.

It is mixed in a dense forest of moonlight, very ordinary. However, in Yan Chong's eyes, which opened up elemental vision, the yellow and green are obviously purple, which is more abrupt.

Two meters away, Yan Chong found another plant and quickly picked it again.

The moonlight grass dies quickly after being pulled down, so it can be stored in ancient elves leaves. However, according to the knowledge of potions, its picking requirements are still required, and the root system must be complete, otherwise the value will be greatly reduced.

If you want to pick all of this moon grass and then carefully select the moon grass among them, it is obviously not advisable. Because the moon grass itself has the opportunity to evolve into a moon grass, and without a huge base, the moon grass will also disappear.

"What's wrong? Is there any problem?" Maxim also picked some moon grass along the way, probably for samples. Seeing Yan Chong's targeted actions, he couldn't help but walk over curiously.

"Nothing." Yan Chong shook his head. He didn't want to reveal his ability to distinguish Moonlight Grass for the time being.

After carefully observing the moonlight grass, Yan Chong felt slightly relieved.

"I just saw several students from the Pharmaceutical Department also studied here," said Maxim. "I have no clue as to how they look."

"I have encountered difficulties in doing tasks. Can I ask the teacher?" Yan Chong asked.

"How to say, some tasks are actually published to students by the college that feels that the cost-effectiveness is low, and there is no need to dispatch advanced professionals."

"Of course, this time it's a bit strange. Jingyue Lake is a very important place in the forest. It's the first time I heard that there is a problem with the water quality. It's impossible for the school to ignore it."

"In other words," Yan Chong guessed, "maybe the college is helpless and can only issue tasks and try its luck?"

"Maybe, who knows." Maxim shrugged, and suddenly, he looked to the front left and shouted: "Teacher Francis!"

Yan Chong looked over and saw a middle-aged man wearing old-fashioned black-framed glasses wearing a college dress - a white shirt, brown vest and black trousers. His hair was combed meticulously and his face was rigorous.

"It's Maxim, are you here to do the mission?" Hearing Maxim's voice, his expression remained unchanged and nodded.

"Yes, teacher, I have taken the task of investigating water pollution." Maxim took a few steps forward, with a look of embarrassment on his face.

"Have you found any problem?" Francis asked.

"No."

"Don't expect me to help you. The college asked me and other teachers in the department to investigate immediately, but nothing was discovered." Francis shook his head and said.

"The release of this task is actually to prepare a research team within the college to convene interested students and teachers to study."

"Because everyone has a premonition that this unknown substance that pollutes the lake water is likely to be a rare new element."

Francis said, taking out some equipment and preparing to start the experiment by the lake.

Yan Chong hesitated for a moment, walked up and asked, "Teacher Francis, is it possible that it is the devil?"

Francis was lowering his head and fiddling with bottles and jars. Hearing this, he raised his head and looked at Yan, and a smile appeared on his serious face: "This classmate is very imaginative, but this situation has been ruled out by us."

"You may not have been exposed to advanced potions? Universal reagents can detect elemental deviations in water quality. If the color does not change, this is also possible - such as light and dark elements."

"However, the light and dark elements are quite special. If the lake water contains dark elements, as long as light magic is injected, the universal reagent will change color, so that it can be detected."

Yan Chong nodded and said nothing.

"It seems that the thin black line is not a dark element."
