Therefore, there is a layer of calcium sulfate in this ground, and the ground is eroded, and the reason is very clear, it should have been eroded by sulfuric acid.

"I analyzed it, and it is not like this sulfuric acid is sprayed manually with a watering can, because the distribution is relatively uniform, and there are many low-lying places, so some sulfuric acid should flow out." Professor Xu explained.

"Under what circumstances would you need to put so much sulfuric acid in it?" Liu Pengcheng asked.

"I don't know about this, I just met Professor Luo today, I called her over, she studied it, but gave me some ideas," Professor Xu said, "Then we verified it, and basically decided that what Professor Luo said was right." In this room, there should have been a large number of lead-acid batteries, and these sulfuric acid should be the aging dew of lead-acid batteries. From here, some powders of lead sulphate were indeed found. ”

"I once talked to Dr. Zhao, and he said that this should be the Tianxian liquid that I had released before, and I also checked this Tianxian liquid, and it does not need to be refrigerated, that is to say, it does not need a power supply. It seems that there is something else in this, but we don't know. Liu Pengcheng said, "And this thing should be the key to the people behind the scenes who want to stop our construction." ”

"It's not necessarily about stopping the construction," Professor Lowe said, "I feel like it's just trying to confuse the public and make the workers focus on the haunting." In this, this situation has occurred in more than one room, and there are lead-acid battery leaks in many houses, which means that there are a lot of batteries in it, and it is very long, I am afraid that it will be more than a few years. ”

"I feel that something is wrong here," Liu Pengcheng said, "Mr. Feng, when he opened the room of the air-raid shelter, he found that there was something inside, and he informed the hospital after a brief glance. Later, the hospital sent someone to deal with it, and it was obvious that Mr. Feng did not carefully investigate what these things were, but the hospital was a little panicked, thinking that the workers had discovered their secrets, so they tried their best to confuse the public. ”

"So, that's right." Professor Luo said, "It seems that there is more than just Heavenly Immortal Liquid in this. You must know that the immortal liquid doesn't take up space, and it can be put in the office, so it won't be piled up in it. ”

"Equipment that used to require long-term electricity consumption" Liu Pengcheng thought for a while, "and it is not a fair and honest thing, in a place like a hospital, it is difficult not to have anything to do with refrigeration equipment and corpse storage equipment."

"Yes!" When Professor Luo heard this, "What you said makes sense! ”

"Looks like I'm going to have to go back." Liu Pengcheng said.

"Don't worry, it's rare for you to go back," Professor Xu said, "It's not necessarily useful for you to come back now, the top priority is to find us a reliable old staff in the hospital to ask." What about that Dr. Zhao you are talking about? Is it credible? ”

"Absolutely, I'll get him to contact you right away."

After hanging up the phone, Liu Pengcheng immediately called Dr. Zhao, and the two exchanged pleasantries for a long time. When it comes to this topic, Dr. Zhao really has some clues.

"You asked me to check recently, and I really found something," Dr. Zhao said, "As far as I know, this air-raid shelter has been used by Dean Wang, who is in charge of logistics, before, and in addition, Director Li of the laboratory department has also often passed." ”

"Laboratory?" Liu Pengcheng thought of something all of a sudden, "All the workers before obviously fainted and fell, but every test was normal, is there something wrong with the laboratory department?" ”

"Director Li?" Doctor Zhao was taken aback, "It's impossible, Director Li has been in the Fourth Academy for 12 years, and he has always been diligent."

"What rank is he?" Liu Pengcheng asked.

"Chief physician, but seniority is older than me."

"Seniority is older than you, but you haven't been promoted to a higher level." Liu Pengcheng probably had some thoughts, "Doctor Zhao, you're not good at handling cases or anything, don't get involved in this matter, but I have friends over there, if you have time, help them more." ”

"That's no problem," Dr. Zhao agreed, but he unconsciously thought about something more.

After opening up these relationships, Liu Pengcheng didn't continue to worry about it, and Xiao Gu really impressed him!

is not only the agility of the military, but the key is that the popularity is also good, and the two professors of the family came to help, which is still very face-saving for Xiaogu.

It's just that Liu Pengcheng didn't expect that Xiao Gu would be able to surprise him so soon.

After Liu Pengcheng told Xiao Gu the relevant information, Xiao Gu adopted a very simple plan - tracking. His sense of investigation and anti-investigation is naturally no problem, and it is impossible for Director Li to discover Xiao Gu.

Kotani only followed it for three days and found several problems.

Director Li's home, located at 3-302 Yufeng Beili, Shangfeng District, Yuhang City, is a 90-square-meter two-bedroom apartment, which is basically public in the old hospital system, but Director Li does not like to go home after work, and usually goes to the tea room by the West Lake.

The fourth courtyard is very close to the West Lake, but this tea room is located on the west side of the West Lake, and there are relatively few tourists, so few people will come if they don't know about this place.

Xiao Gu probably inquired, this tea room is still relatively famous, all the tea is the local West Lake Longjing, and the quality is very good, any cup of tea is three digits, which is higher than the daily salary of most people.

Xiao Gu didn't go in, so he waited patiently near the tea room, and each time he waited for three or four hours, and he followed him like this for three days.

Two days ago, Director Li came out of the tea room and went home directly, but not on the third day.

This day is the weekend, Director Li came to the teahouse in the morning, at eleven o'clock in the morning, after leaving the teahouse, Director Li got into a crown car, Xiaogu did not follow directly, but found Liu Pengcheng, Liu Pengcheng helped contact the traffic police department, let the traffic police help, and followed the car with monitoring all the way.

The crown car did not go home directly, but drove to Tongxian in one breath and stopped at the door of a private hospital.

By the time Xiao Gu caught up, Director Li was gone.

Kotani's appearance didn't have much presence, he wore a mask and entered the hospital alone. There are quite a lot of people in the hospital, it is more lively than expected, Xiaogu probably took a look, and many of them are tourists.

Bringing tourists to the hospital? It's also a novelty. After inquiring, I learned that this place sells a famous medicine, called "Beverly Medicinal Wine", which can strengthen the body, and basically the bus of the tour group will bring people over.

In addition to Beverly Medicinal Liquor, it also sells a variety of high-end health supplements. Ginseng, deer antler velvet, saffron, Ganoderma lucidum, fish gelatin, and fur seal pills can be described as dazzling. Kotani blended in with the crowd, no one paid attention to him, and the place was not even monitored.

After walking around here for two or three times, Xiao Gu didn't find where Director Li went, this hospital has a total of three floors, except for the president's room and the vice president's room, you can't see the structure inside, and the others have windows. (End of chapter)
