Back at the villa, Wang Chen didn't mention the café to Jack and Ellie, let alone the proprietress herself, he just said that he suddenly thought of it.

"Hearing Mr. Wang say this, it's really very possible!" Ellie poured Wang Chen a glass of water and said her opinion casually.

"We were really too hasty and only saw the surface of the problem! Because even if there is a research and development point for potions in this city, they will definitely not be on the bright side! Think differently, what would we do if we were those people? Jack whispered.

"Mr. Jack, what do you think is the least suspicious?" Wang Chen asked Jack.

"Hospitals, schools, and local government departments." Jack said casually.

"Government departments can be excluded, and state-owned hospitals and schools can also be excluded, because they are all the property of the state, and the person in charge does not have so much power and courage!" Wang Chen said.

"So that's the only thing left with private schools and hospitals?" The viper uttered the last word.

"Where's the building datamap?" Wang Chen asked Jack, who immediately took out the data map and placed it on the table, and everyone checked the location of private schools and private hospitals together.

"In the entire city of S, there are a total of eleven private hospitals and fifteen private schools, and there are three private hospitals and two private schools in this most suspicious area!" Wang Chen pointed to the data map and continued: "Do you think it is more likely to be the periphery, or is it more likely to be this suspicious area?" ”

"Mr. Wang just said that the more impossible the place, the more likely it is, I think we should start from the periphery!" Ellie said.

"Nope." Ellie's words fell, Wang Chen shook his head, and said, "Let's start with this suspicious area!" If not...... It's never too late to check the periphery! ”

"We're going to waste days! You know, it's not just about finding their R&D sites, we have to destroy them, arrest those involved in R&D, and bring them back to the UN for review! It's definitely harder and more time-consuming than finding them! Ellie said.

"Ellie, you're too anxious, you should listen to Mr. Wang first." Jack Craze glanced at Ellie, looked at Wang Chen and said, "Mr. Wang, you continue." ”

Wang Chen nodded and said, "Actually, Ms. Ellie's words are not all unreasonable, the more impossible it is, the more likely it is!" But Ms. Ellie, if you think about it, the group of mercenaries we met by chance at the seafood shop didn't happen to us, and we didn't know they were mercenaries at the time! ”

"Then the mercenaries clashed with the local police, and they already had guns, what does that mean? This shows that when they were in the seafood shop, they had already got potions and firearms! ”

"As for the clash they had with the local police and the fight that happened to us, these were things they didn't expect, so ...... I advocate starting with the suspect area! ”

The words fell, Ellie nodded, didn't say anything more, Jack said, "Now that the speculation has been made, the rest is practice!" Everybody...... It's time to go! ”

"Divided into four groups, first check the three private hospitals, and Chen Fei and I go to the private colleges and universities in the north to check them! Again, after discovering the accident, come back and report it immediately, don't act rashly! Wang Chen quickly assigned the task, and everyone nodded and began to work separately.

The operation took three days, because hospitals, schools, and factories were different from factories and villas, and each place had to be carefully inspected.

Three days later, in the early morning, the crowd gathered in the living room.

"Nothing suspicious was found in those three hospitals." War Leopard and others said.

"There is nothing suspicious about that university." Wang Chen frowned, now there is only one last private school left, if there is no more...... It's really time to check the periphery! Did you make a mistake in your inference? Wang Chen was silent.

"The remaining private school is an elementary school, at 365 Xisan Road." Jack looked at the data map and said softly.

"Chen Fei, Night Fox, the two of you are the most cautious, the last place, the three of us go!" Others stay here and wait for news. Wang Chen said.

"Good!" Everyone responded, and the atmosphere in the living room was a little depressing, ten days had passed, and there was still no progress in this matter.

At nine o'clock, Wang Chen, Li Chenfei and Night Fox came to this elementary school, today is Thursday, there are many students, but this does not prevent the three of them from sneaking in.

Due to the dense flow of people during the day, the three of them did not make much progress, but only checked the playground and other places that were not easy to be noticed. In the evening, the school gates were closed, and the trio infiltrated again.

Wang Chen made a gesture to Li Chenfei and the night fox, which meant that Li Chenfei went to check the teaching building in the south, the night fox went to check the teaching building in the north, and he went to the library and equipment room in the middle by himself.

The door lock is like nothing to them, and it can be easily broken with a single wire, leaving no trace.

In the early hours of the morning, the three of them gathered at the entrance of the passage, and each shook his head, indicating that he had found nothing.

"Let's go, maybe it's really on the periphery." Li Chenfei said softly, and the night fox also nodded in agreement, Wang Chen didn't say anything, and the three of them prepared to leave.

But at this moment, Wang Chen's eyes were locked on a plaque at the bottom of the corridor, which said three words laboratory, but this was not the strangest place, the strange thing was ...... There's a warning sign prohibiting entry!

Everyone knows that elementary school students like to run around the most, but they are afraid of the teacher, which is probably something specially set up by the teacher to prevent elementary school students from running here after class.

It stands to reason that this is also a very normal thing, but at this juncture, Wang Chen feels very abnormal!

"What's wrong?" Nightfox asked softly.

"Which lab you checked?" Wang Chen asked at the night fox.

"Yes, it's less than fifty square meters, and it's full of some inconsequential experimental props, and I came out after a glance." Night Fox said casually.

"Don't you think that warning sign is suspicious? A laboratory is locked, what are you doing with warning signs? Is it possible for elementary school students to open the door lock? Wang Chen asked softly.

When the words fell, Night Fox and Li Chenfei's faces changed, they glanced at each other, and the three of them walked towards the laboratory in unison.
