Looking at Lu Tianyu who ran out wildly, Qiu Wei was in a hurry, jumped up from the stool and prepared to chase him out, if he let this guy talk nonsense everywhere, in case Lu Dong knew about it, then his hard work in the past few days would not be in vain.

"Forget it, let him go." Director Zhang stretched out his hand to stop Qiu Wei.

"Director, if he tells Lu Dong about this, then ......" Qiu Wei looked anxious.

"I believe in Lu Tianyu, if he doesn't even have this awareness, it can only mean that I really see the wrong person." Director Zhang said with a slight sigh.

…………

Rushing out of Manyun Cafe, Lu Tianyu only felt dizzy in his head, everything that happened just now had too much impact on him, he couldn't believe that Director Lu Donglu, who had always been respected, would be the mastermind behind the scenes? He didn't want to believe it either!

"It must be Qiu Wei's ghost, this girl is really hateful." Lu Tianyu hated the roots of his teeth.

"No, I have to find a way to come out as soon as possible, and I can't let this girl succeed."

"Do you want to go to Director Lu and ask him directly in person?" Lu Tianyu didn't think about this plan, but finally dispelled this idea.

In any case, this matter is too wide-ranging, especially involving the police to handle the case, if it is self-defeating because of their reckless actions, in case it becomes a big mistake, it will be a real disaster.

Now, there is only one feasible way, which is to find the mysterious person as soon as possible, and only by finding this person will everything be revealed.

But, where is that mysterious man?

Lu Tianyu sat on the stone bench on the side of the road, scratching his ears and cheeks, irritable, and the whole Sun Monkey who had not lost his hair.

"When! While! While! While! "In the distance, the big bell on the roof of a commercial building rang, and the melodious bell sounded far and wide over the city.

Lu Tianyu instinctively took out his mobile phone and looked at the time, dizzy, it was four o'clock in the afternoon, inadvertently, a short meeting lasted for more than an hour, and he was angry, it was really not worth it.

"Hey, no, it seems like four o'clock this afternoon, what else do I have to do?" Lu Tianyu suddenly frowned.

"What the hell is going on? Basketball training, probably not. A date with any girl.,It doesn't seem to be arranged.。 So what the hell is going on? Lu Tianyu's brows tightened, and he began to search in the sea of memory.

A minute later, he finally remembered.

"Mom, I'm going to be late." In a wild roar, someone turned into a red rabbit horse and galloped all the way towards the school's No. 9 teaching building, startling countless ants.

Six minutes and twenty-four seconds later, Lu Tianyu appeared breathlessly at the door of Room 303 of the school's No. 9 teaching building.

Looking at the sign engraved with the words "Third Pharmacology Laboratory" above the iron door, Lu Tianyu knocked on the door with trepidation.

"Come in." A man's voice came from inside the room.

Lu Tianyu hurriedly pushed the door in, and the first thing that caught his eye was a huge experimental table, which was full of various bottles and cans, which were all reagents of various colors, which made people dazzled.

In this pile of bottles and cans, a young man in a white coat was busy and happy, and when he saw Lu Tianyu coming, he turned his head and said with a smile: "You are finally here, I thought you were not coming!" ”

"Teacher Sun, I'm sorry, I have something to do temporarily, so I'm late." Lu Tianyu hurriedly explained.

This young man is Sun Xingguang, this morning he invited Lu Tianyu to help with the experiment, such an important matter, someone almost forgot about it.

"It's good to come, Lu Tianyu, let's start." With Mr. Sun's order, Lu Tianyu officially began his career as an experimental assistant.

"Lu Tianyu, cut this piece of Panax notoginseng into slices, will you cut it? Yes, that's good! Remember, the thickness should not exceed half a centimeter. ”

"Lu Tianyu, after five minutes, heat the red reagent, yes, that, to 100 degrees, and then put it in warm water to cool it naturally."

……

At first, Lu Tianyu was still a little scrambling, but gradually, he got used to it, "It turns out that doing pharmacological experiments is so purple, it's quite simple, but why do I always feel like I'm doing it in the kitchen?" Someone thought to himself as he stirred a lump of rice-like stuff quickly.

Unconsciously, the time had reached eight o'clock in the evening, during this period, except for taking time to eat a fast food, Lu Tianyu had almost no time to rest, the reason was very simple, there were only two people in a huge laboratory, and they couldn't be busy at all.

"Lu Tianyu, I'm tired, today's experiment is almost done, let's stop here. I'll go to the bathroom first, and we'll walk together later. Sun Xingguang was lying in front of a computer just now, crackling at a bunch of tables and numbers, and he had been calculating for more than an hour, and at this time he was already blind, and he couldn't hold on.

"Okay." Lu Tianyu nodded, picked up a rag, and cleaned up the messy experimental table.

Sun Xingguang saw this scene in his eyes and nodded secretly.

After ten minutes, Sun Xingguang slowly walked back, looked at the neat and clean laboratory, and couldn't help but say approvingly: "Lu Tianyu, you are really capable, it seems that my assistant is not wrong." ”

Hearing other people's praise, Lu Tianyu was a little embarrassed, and hurriedly said: "Teacher Sun, it's nothing, this is what I should do." ”

"Well, let's go, it's not too early." Sun Xingguang said as he turned off the fluorescent lights in the laboratory.

"Teacher Sun, don't lock the door yet, I'll take out the garbage." Lu Tianyu quickly picked up a black garbage bag, walked out of the laboratory quickly, and headed for the bathroom at the end of the corridor, where the trash cans on each floor were located.

The bathroom is not large, divided into two cabins, the outer room is a place to wash hands, the inner room is a convenient place, and the trash can is placed in the corner of the outer house.

After throwing away the garbage bag, Lu Tianyu breathed a sigh of relief, the first day of experimental assistant work was finally over, everything went well, and there was no mess, well, this is a good start.

Thinking of this, a smile appeared on Lu Tianyu's face, he walked to the side of the pool, turned on the faucet, and prepared to wash his hands, and then he could get off work.

Just then, something on the edge of the pool suddenly caught his attention.

A crumpled cigarette case was casually thrown on the ground, and the words "Yellow Crane Tower 1916" were clearly visible on the cigarette box.

In an instant, Lu Tianyu's nerves became highly tense.

Who would have dropped the cigarette case?

There were still a few cigarette butts next to the cigarette case, Lu Tianyu squatted down, picked up a cigarette butt, and observed it carefully.

The cigarette butt is printed with the words "Yellow Crane Tower", looking at the tail, it is still burnt yellow, and it should not be long after it should be extinguished, at this time, there are only two people left on the entire third floor, himself and Sun Xingguang.

"Could it be Mr. Sun?" Lu Tianyu suddenly felt his heart beat faster.
