On the fifteenth floor of the Life Science Building, in the cell biology laboratory, in the sterile operation room, the man who had just probed his brain in the little old man's office was sweating profusely holding a cylindrical gas cylinder with a diameter of 30 centimeters and moving his steps with difficulty.

"I'm sorry for you, junior."

The one who spoke out was a woman in her thirties who could be called an aunt, the third senior sister who had a relationship with Yang Tian last time, and the only female student that Zhong officially accepted.

The fine beads of sweat on the man's forehead seemed to be a little more, and he hurriedly spoke, "It's okay, it's okay, senior sister, you don't have to be so polite, it should be." ”

In fact, generally speaking, the workers who supply the gas tank always send the bottles to their laboratory, and then the people in the official laboratory come to pick them up when they need them, or the little old man and his classmates in the laboratory send them over.

The reason why there is such a mechanism is because the mentors of the two families, the little old man and Zhong Cheng, are more familiar in private, and the other reason is because Zhong Chengcheng's research team is more strange.

Well, how weird is it?

Zhong Zheng has only accepted a total of 6 students in recent years, including Yang Tian, and five of them are not in the laboratory all year round, and only one of the fourth is resident, and he is often too busy to hold bottles......

"Senior sister, why are you suddenly free to come to the laboratory?"

The man holding the cylinder finally couldn't hold back, this was the first time he saw this legendary "senior sister" in the laboratory for so many months, saying that it was a senior sister, but in fact, people could have taken graduate students by themselves a long time ago......

"I had something to report to the teacher, so I came."

The woman made an understatement, and then showed a "send-off" smile at the man, who of course said hello and left.

When the man went out, another strong man of about 185 walked in, with a white long-sleeved lab coat, blue rubber gloves, a light blue mask and a hood, and his exposed eyes were full of honesty, this was the fourth senior brother of Yang Tian, who had been stationed in the laboratory all year round and followed Zhong Cheng to do experiments.

He was still carrying out the passage of cells on the sterile operating table just now, and before the alcohol lamp was extinguished, he was temporarily sent by his senior sister to find something, and only came back at this time.

The fourth senior brother glanced at Zhong Cheng, who was separated by three layers of glass and a laboratory ten meters away, carrying the gloves he had just taken off in his left hand, and holding his mobile phone in his right hand, not knowing who he was talking to.

Turning his head to look at the senior sister in front of him, the fourth senior brother had a simple face, "Senior sister, what's wrong?" ”

"The wrench you were looking for?"

"Here's it."

The fourth senior brother handed the wrench in his hand, and the third senior sister over there took it and wanted to put it on the gas tank, but after thinking for a while, she retracted her hand, "What, go get some soapy water." ”

Now the fourth senior brother knows what she is going to do.

Screw the cylinders!

The point is that most of the bottles of the gas companies that work with the laboratory are in disrepair and rusty, and the most important point is that it always leaks!

Therefore, every time a new gas cylinder is delivered, everyone should drop a little soapy water on the valve at the top of the cylinder to see if there are any bubbles bulging out on it, if there are bubbles, it means that there is a gas leak.

And it's very bad, this time the gas cylinder is still leaking.

The third senior sister and the fourth senior brother stared at the bubbles coming out of the top of the gas cylinder and picked up the wrench.

This is a special unique secret invented by the senior brother who is now in Germany - first loosen the valve, and then tighten it, many times this trick is on it, and the gas cylinder will not leak.

Originally, this should have been done by the fourth senior brother, but now that the third senior sister picked up the wrench and began to do it calmly, the fourth senior brother chose to watch with his big honest eyes.

Well, after all, the third senior sister is also an elder, isn't she?

But the valve of this cylinder seems to be a little too tight today, huh?

The third senior sister twisted it a few times, but the valve did not move at all, and the cylinder always rotated, so it couldn't be used at all.

However, the senior sister is also in a leadership position in the hospital all the year round, full of momentum, and waved her hand, "Come and hold the bottle for me!" ”

The fourth senior brother obediently hugged the bottle, and then the third senior sister calmly took the wrench and unscrewed it, this time it was not bad, the wrench slowly began to twist the screws, gradually, more and more loose, more and more loose.

The fourth senior brother was a little uneasy, but he had done this in the past, and it seemed that nothing had happened......

Always feeling that something was wrong, the fourth senior brother retracted his head slightly, but he still felt that something was wrong, so he turned his head to the side again, and staggered the valve facing him.

……

"Oh my God...... You said you, what are you doing badly, but you want to bump into the hands of the old bull, it's really ...... Alas, it's a bit of a trick! ”

Zhong Cheng's somewhat distorted voice came from the microphone, Yang Tian could hear the helplessness in his tone from so far away, and couldn't help but shake his head and smile bitterly, it seemed that he was really in trouble this time.

But if the matter were to be repeated, and there was no way to determine whether the child was really sick or not, Yang Tian still couldn't just walk away......

This is not only a matter of morality and principle, but also a matter of the bottom line of being a human being!

Yang Tian sighed here, Zhong Zheng sighed over there, and then Yang Tian heard that there was saying to himself:

"That old man's temperament is very stubborn, and he can't pull back the eight donkeys, let alone me, not to mention that with my understanding of him, this thing has happened for so long, he must have made trouble, and it is estimated that the principal and vice principal will know about it at this time."

Zhong's formal analysis made Yang Tian speechless, according to the previous short period of contact, Yang Tian had already discovered that the little old man had some explosive personality, and this situation was really very likely to occur!

"I said, Yang God, I know your ability, and I believe that you will definitely be able to break into the national competition, but you don't have to keep an eye on this year."

Zhong officially began to persuade Yang Tian bitterly, and Yang Tian was very determined when he told him that he was going to compete, so he admitted it, but now he began to think about it.

It is said that only he and the fourth child stay in the laboratory every day in their laboratory, and the huge laboratory is very empty!

It just so happens that there is a project in hand, Xia Bin has no time to do it, isn't it also excellent to catch Yang Tian to do the project?

"You're only a freshman now, and you still have four chances in the future, why don't you accumulate a little more and then accumulate a lot?"

Zhong's formal reason is also very sufficient, originally, if Yang Tian is so demonic and seems to know everything, he has studied medicine for many years, which freshman is qualified to participate in this kind of competition! I'm sure I've been brushed off in the preliminary round!

Although I heard that Wang Zhi's group is very good, but this year's juniors and seniors also have a few good seedlings, if Yang Tian still wants to participate in the competition, he will catch them and form a team?

How simple it is!

It's a pity that Yang Tian didn't appreciate it, and directly rejected Zhong's formal suggestion, he only had one chance, so he could only seize it firmly.

"Okay, I'll talk to him later, but ......"

"Bang!"

"Bang la la la!"

"Crackling!"

Zhong was only halfway through his words, but there was an earth-shattering explosion on the other side of the phone, followed by a chaotic sound, and Yang Tian faintly heard the sound of many glassware breaking.

"Teacher? Teacher?! ”

"Doodoo ......"

The phone was hung up in the midst of the noise, Yang Tian looked at the mobile phone in his hand with a confused expression, and his mouth opened to the boss.

What's going on......
