And the woman who questioned Zhang Tianjiu was very young, she looked to be in her twenties and less than thirty, and judging by her chestnut hair and slightly sunken eye sockets, she was probably a second-class caste Sher. People of different castes have a clear mark on their identity card, and most of the upper class people will directly enlarge this sign and mark it on their clothes to show their status. Thus it is also a reminder to people from the lower castes not to rush into themselves, otherwise they will face sanctions.

The maroon-haired young girl, even if she was a Sher, would not have marked her clothes. It's a ghost market, full of inferior people, and if she, a girl from a second caste, reveals her identity, she may be targeted at any time. She is not evil.

Moreover, judging from her dress, she is Dr. Luo Cheng's assistant, and Dr. Luo Cheng is a member of the Changnan tribe of the fourth caste. Showing his aristocratic status in front of the teacher is purely uncomfortable.

But just because she was polite to her teacher didn't mean she would be kind to other lower castes.

No matter how educated she is, the habits she has cultivated in such a respectful environment for a long time will still make her naturally despise inferior people.

Zhang Tianjiu smiled innocently.

The girl from Sher wanted to scold him, but when she saw this kind of smile, she swallowed back the words that came to her lips. Although this bald head is not handsome, at least it is not annoying.

"Doctor, shall we make a deal?"

Zhang Tianjiu said with a grin.

Dr. Luo Cheng has gray hair and looks like he should be in his seventies. In this era, the seventies are in the prime of life.

"He's not a security guard, he doesn't have the sign of our hospital. ”

The male assistant, who had been silent, said suddenly.

This person is in his thirties, and he knows by his appearance that he is from the Changnan tribe.

The Sher girl's eyes suddenly raised, and she said very vigilantly: "Who are you? What are you doing here? Get out immediately! I warn you, if you don't go out again, I'll call the security guard!"

"Girl, I have no ill intentions, I really came to make a deal with Dr. Luo. ”

Zhang Tianjiu hurriedly said, trying to make his smile more sincere and charming.

Seeing that the Sher girl was still angry, Dr. Luo Cheng stopped her with a wave of his hand, looked at Zhang Tianjiu expressionlessly, and said, "What deal do you want to make with me?"

Truth be told, the doctor is also weird.

The guy in front of him looks like a big-headed soldier, he is young, and his education level is definitely not high. What can he do with himself?

"I've got some CRT in my hand, and I'd like you to help me refine it. ”

Zhang Tianjiu said bluntly.

Dr. Luo Cheng changed color and shouted, "You are a drug dealer?"

Zhang Tianjiu scratched his head and said in surprise: "Doctor, with your attainments in the field of biochemistry, is it true that in your mind, CRT is just a drug?"

Suffocate Dr. Luo Cheng!

Of course, he knows that CRT is not just a drug, and it can even be said that drugs are just an "incidental function" of CRT, and the main function of CRT is to promote cell regeneration.

But Zhang Tianjiu's virtue, won't people associate him with drug dealers for the first time?

Who is to blame for growing like this?

"So what are you going to do with the CRT?"

Dr. Luo, who was choked by Zhang Tianjiu, snorted.

Zhang Tianjiu didn't say a word, so he took a pack of solid CRT from the small cart next to him and threw it to Luo Cheng.

Thirty kilograms of CRT is a lot, and Zhang Tianjiu brought it in a storage ring. Blatantly pushing thirty kilograms of high-purity solid-state CRT on the streets of the ghost market is definitely a brain water.

No matter how awesome Zhang Tianjiu is, he can't stop wave after wave of drug dealers who rush up regardless of life or death.

Thirty kilograms of CRT, how much does that have to be?

Worth the life of the second young master of the governor!

Dr. Luo Cheng took the CRT, opened it and looked at it, his face sank completely, and he snorted: "Young man, are you here to tease me? This is already 99% pure CRT, how can you purify it?"

At the current state of the art, this is already the highest purity.

Zhang Tianjiu shook his head again and again, and said, "Doctor, so, what is the most terrifying thing about scientists? Once the brain is rigid and sets limits for itself, it is impossible to make any progress in scientific research. Thirty years ago, there was no such thing as CRT, so how can you be 100% sure that this is the ultimate form of CRT?"

Dr. Luo Cheng is worthy of being a biochemical expert, and when he heard this, he was stunned for a moment, and immediately said, "You mean, upgrading?"

The tone was uncertain.

It is normal for the biochemical field to be updated, but it should not be said by someone like Zhang Tianjiu.

This is out of bounds!

Zhang Tianjiu still had that harmless smile on his face, and said: "Doctor, I have a way to continue to purify CRT, and I will teach you this method, on the condition that you help me purify all the thirty kilograms of CRT." I'll give you seven days at most. In seven days, we'll have to get out of this place. ”

"You brag!"

The Sher girl immediately expressed her opinion.

Dr. Luo immediately said, "Young man, there is a full set of equipment here, you can show me." ”

The brains of real scientists are different, and they are never in a hurry to deny it.

Good scientists must firmly believe in one thing: anything is possible!

Moreover, Zhang Tianjiu just looks like a little ruffian, what if he is really a scientist? No one has engraved the word scientist on his brain.

"Teacher ......"

The Sher girl was a little anxious.

This guy obviously has an unknown origin, why didn't the teacher call the security guard, but asked him to demonstrate something?

What if it's a bad guy?

Dr. Law was unmoved.

Zhang Tianjiu was not polite, walked over very confidently, and began to fiddle with various test tube instruments. In less than a minute, the face of the Sher girl changed.

This skilled is obviously an old man.

It's nothing to say, in another time and space, in order to please Amy, Zhang Tianjiu accompanied her to tinker in the laboratory. Amy is the kind of workaholic, and she has no objection to having fun with men, but it's best not to take up too much of her time.

Zhang Tianjiu thought about it, everything was done in the laboratory, and it seemed to be the best of both worlds.

Wouldn't it be beautiful to do experiments together, discuss unknown scientific fields together, eat together, chat together, and do some exercises together that are beneficial to mental and physical health when they are resting?

Amy's evaluation of Zhang Tianjiu is like this: he is ugly, has a flexible brain, has a lot of ghost ideas, and his hands are particularly skillful.

If it weren't for the fact that Zhang Tianjiu was the trump card among the genetically modified warriors, Amy would have transferred him to his side as an assistant a long time ago, saving this guy from hooking up with girls everywhere. Although Amy never considered herself to be Zhang Tianjiu's real girlfriend, she positioned her relationship with Zhang Tianjiu as "a partner who does some pleasant sports together". But if you can dominate this partner, of course, it will be the best.

The super GM warrior's strong physique and almost endless energy are really not covered!

You can be cool as many times as you want, and you can be as cool as you want!

Now Zhang Tianjiu didn't show his best state at all, just a casual demonstration was enough to calm these three people. Especially Dr. Luo Cheng, his eyes are shining.

Such an experimental assistant is simply hard to find.

However, Dr. Luo's attention was soon attracted by the purification method demonstrated by Zhang Tianjiu.

I saw that after Zhang Tianjiu added a few ordinary catalysts, the aqueous solution of CRT, which had reached 99% purity, had a chemical reaction again.

"How can this be?"

Soon, the first batch of purified CRT appeared in front of Dr. Luo's eyes.

Dr. Luo immediately took a little bit and put it under the microscope to observe, sure enough, the molecular formula of CRT has changed a new way, whether the purity is different from before, it is not certain for the time being, but it must have changed.

But it's still CRT.

Dr. Luo is sure of this.

"Doctor, in fact, CRT can be improved, now it is the first generation of CRT, and after the improvement, it will be the second generation, then the third generation, the fourth generation, the fifth generation, the sixth generation, and it will continue to be improved, as long as you can find the right way. ”

Zhang Tianjiu stood up with a smile and said.

Dr. Luo couldn't help but nod his head again and again, his expression quite excited. Further improvement of CRT has always been one of his research directions, but unfortunately no breakthroughs have been made, who knows that this young man who appeared out of nowhere easily solved the problem that has plagued him for many years. It's really hard to find a place to step on the iron shoes, and it takes no effort to get it.

"Well, Doctor. Here are 30 kilograms of CRT, please purify them all. Remember, there are only seven days, and I'll pick it up after seven days. Then you have to get out of here. The army of monks will soon be coming, and the Wehrmacht will not be able to stop it. ”

The Sher girl asked suspiciously, "Sir, what is your surname?"

Zhang Tianjiu repeatedly mentioned leaving, and it seemed that he was in his chest. But she is well aware that the city of Noray has long been in place to ban air traffic, and no spacecraft is allowed to leave without the permission of the government and the military.

The great nobles naturally have nothing to worry about, they have privileges. The government and military will also prioritize their safe departure. Many minor nobles are in a hurry, and are looking for a way to get around, hoping to catch the last spaceship and escape from this mortal city.

This man is just an inferior soldier, why can he be so confident?

Unless he is someone from the military headquarters.

This is a good explanation for why he has so many CRTs.

Zhang Tianjiu smiled: "My surname is Zhang." Please, doctor. ”

Another question to the Sher girl, pretending not to hear.

Dr. Luo Cheng said suspiciously, "Why don't you do it yourself?"

Judging from the proficiency of Zhang Tianjiu's demonstration, he has done this more than once, and he is familiar with the road.

"Hehe, I have other things to do, I'm very busy!"
