Wang Luzhi has been running around for the factory sewage case these days.

He went to Mr. Saku's hometown to inspect the situation and took many photos with the camera he borrowed from Miss Fei Yingri.

The factory wastewater is discharged into the river, but it needs to be properly treated before it can be discharged, but the factory in Mr. Saku's hometown is secretly discharging untreated wastewater.

It was a paper mill, and the wastewater produced by this type of plant contained many substances, including harmful chemical inorganics, as well as precipitated solids, volatile phenols and other organic compounds.

After these substances enter the river, they will dissolve oxygen in the decomposition process, reducing the oxygen content of the water body, thus affecting the survival of organisms in the river.

The local rivers already have a stench and there is a mass death of life in the water, which means that organic compounds such as methane have been generated.

Wang Luzhi took the photo in his hand and was about to go back and think about the next step, but he saw a person downstairs in his apartment.

He was a little strange, how could the little detective appear here, it couldn't be that he came to him.

Wang Luzhi walked over, "Conan-kun, are you playing here?" ”

Finally caught this guy, since he got a test antidote from Gray Plains, Conan has been planning to find a reasonable time to appear in front of Mao Lilan and Wang Luzhi.

As a result, Wang Lu often went out early and returned late in the past few days, which did not match his schedule as a primary school student, and he was not even in Tokyo for the past two days, which made him empty every time he came.

Conan found out from Mao Lilan that he would be back today, so he went to the downstairs of Wang Luzhi's apartment after school to block people.

He slandered you in his heart for playing, a foodie who eats every day, but he raised a smile on his face, "Brother Lu, are you free now?" ”

"Not really." Wang Luzhi had to go back and sort out his thoughts, "I still have some things, Conan-kun, see you next time." ”

Conan didn't expect this guy to leave directly, so he hurriedly stopped, "I have a very important thing to tell you, wait first!" ”

Wang Luzhi saw that his face was serious, so he stopped, he raised his wrist, and looked at the time on his watch, it was already early six o'clock.

"It's time to eat, then I'll take you to have a meal, and we can talk while eating."

He can also solve the problem of an empty stomach, which he has been thinking about just now and has not yet felt, and as soon as he stops, his stomach begins to protest.

Sure enough, he was a foodie, but Conan himself was a little hungry, so he didn't refuse and followed Wang Luzhi to a ramen shop.

…… Thinking that this guy would take him to something delicious, Conan thought silently, those cops sometimes took him to dinner, at least a pizzeria or something.

Even the slightly picky Mori Kogoro would order him a decent bento box downstairs, not to mention other rich adults.

"Conan-kun, I'm a poor international student."

Wang Luzhi saw the disappointment on Conan's face, and he said, "Ramen is also a delicious thing!" Cheer up, I'll allow you to order a set meal with two servings of meat. ”

When others invite them to eat, there shouldn't be too many requirements, Conan casually ordered a tonkotsu ramen, and the price is not high among the crowds.

Wang Luzhi brought himself a set meal with a lot of barbecued pork.

"What's the matter?"

While waiting for the ramen to be cooked, Wang Luzhi asked.

"This weekend, we will go camping, and we want to invite Brother Lu to go with us." Conan said, "Sister Lan also promised to come. ”

Invite him?

Wang Luzhi felt that something was wrong, "You mean with those children?" ”

Conan nodded, "There's Ayumi, Mitsuhiko, Motota, and Gray Hara and Dr. Agasa. ”

Remembering that Wang Luzhi didn't seem to know Dr. Asasa, he added, "Dr. Asa is a relative of Gray Plains. ”

It's really weird, "I don't know them very well, why are you looking for me to go camping?" ”

"Because you need one more person to drive." Conan had already thought of his rhetoric before, "Doesn't Brother Lu know how to drive?" ”

While the two were chatting, the ramen was delivered.

Wang Luzhi picked up a piece of barbecued pork and drowned it in the soup, "But I don't have a car." ”

"It's okay, we've got the car ready."

…… Why did this little detective have to go camping with him?

Wang Luzhi felt that there should be nothing good, and he refused: "I'm sorry, I have something to do on the weekend." ”

This is not a lie, he does need to be busy with the case of factory wastewater.

"But Sister Lan will also come along." Conan reminded.

"Okay." Wang Luzhi took a bite of barbecued pork, although he had some firewood, he could bear it, "You guys have fun." ”

Seeing him eat ramen, Conan was a little confused, how could this be different from the plot he had in mind.

But Wang Luzhi didn't appear, how could he carry out his own plan, Conan suppressed the slight impatience in his heart, and he persuaded: "It's fun to go camping on the weekend." ”

"I'm sorry, but I'm not interested in that."

Wang Luzhi has a mosquito-sucking physique, and he is basically insensitive to such activities.

Others go camping to enjoy the tranquility of the wilderness and the scenery of nature, and he goes camping to burn himself and feed the mosquitoes.

Seeing that Wang Luzhi was serious about cooking and didn't want to take care of himself, Conan thought about it and released a big move, "Brother Shinichi will also come." ”

This sentence really attracted Wang Luzhi.

Is this about to change the living?

He's really a little interested, high school students have become elementary school students, and hard explanations can explain a little bit of truth, after all, from a material point of view, it is a decrease, but it is too bizarre for elementary school students to become high school students again.

Wang Luzhi had picked up Conan before, and felt his current weight, which was no different from a normal child.

How did you suddenly grow so much flesh when you only had so much weight?

As an unswerving materialist, at least in the past, Wang Luzhi wanted to ask: Can you let him watch the change.

It's a pity that he can't really ask, Wang Luzhi doesn't want Conan to know that he has guessed that he is Kudo Shinichi, and it feels like it will be a very troublesome thing.

Although the system is prompting him to continue learning about the organization, the current task has nothing to do with the organization.

Therefore, Wang Luzhi can know about the organization, but he is not eager to know, and he will talk about it when he has time.

Conan had already seen that Wang Luzhi was interested, and he knew that the other party would definitely care, after all, he had told Wang Luzhi that Kudo Shinichi and Mao Liran liked each other.

He asked, "Brother Lu, are you coming?" ”

Wang Luzhi thought about it for a while, and it was worth wasting a day to see the big changes that I didn't know if I could see.

Seeing that he was still hesitating, Conan said: "I really need Brother Lu, otherwise only Dr. Asa will drive, then there will only be one car, and there will not be enough people to sit." ”

Wang Luzhi agreed.
