super exchange system

Haishi University is regarded as the face and representative of Shenhai City in the academic world, so its laboratory has gathered many equipment that ordinary school laboratories do not have. Because of this, it is conceivable that Su Linjiang has used up a lot of equipment in this laboratory. kung fu.

The two schools clearly share the same street, but the atmosphere inside the school is completely different. It was still light at seven o'clock in the evening, and Bai Han saw some students sitting on the benches reading, which is totally invisible in Lingnan School. Bai Han belongs to Lingnan, but at this moment he sincerely admires these prestigious students. They have put in a hundred times the effort of ordinary people. If the bright future does not belong to them, who should it belong to?

Bai Han once again silently warned himself that only by working hard can he live up to himself!

"Hey, Xiao Su, why are you coming to the lab so late?" When the two of them were walking towards the lab, they accidentally ran into an old man with white hair. My friend is going to the lab."

That Professor Li was wearing presbyopic glasses, and after listening to Su Linjiang's words, he noticed the white man beside him, and raised his head slightly: "Oh, this is the person who asked you to borrow the laboratory?"

It turns out that this old man is the professor of the school, and most of the old men who appear in this school bear the title of 'professor'. Now that he was mentioned, Bai Han immediately leaned over to the old professor respectfully. : "Professor, hello, my name is Bai Han."

Professor Li nodded slowly, but looked at Bai Han with scrutiny. Today, as he was going to enter the laboratory, Bai Han didn't bother himself too much, and he was still wearing a round-neck T-shirt. Look too young.

"Boy, are you from our school?" Professor Li asked tentatively, Bai Han shook his head, and said a little shyly: "I'm not from Haishi University, this school is so good, how can I have that ability, I'm on the opposite side Listening to the south."

Professor Li's eyes immediately became sharper, and his voice rose a few tunes: "What, students from Lingnan, how can you come to our school to do experiments?"

Su Linjiang frowned: "Professor, our school has cooperated with Lingnan School in the past few years. Several machines in the laboratory were jointly purchased by the two schools. There are messages on the campus website saying that students from Lingnan are welcome to come to our school. Exchange and study, not to mention that I have already submitted an application report to the school." Needless to say, Professor Li understands the rest.

He raised his eyes resentfully: "Hehe, you're right, you're right, I'm just worried that the students in Lingnan haven't learned how to do experiments systematically, and I'm afraid they will damage the equipment in the laboratory."

"Professor, don't worry, I will watch him while he is doing the experiment."

"Hehehe, that's good, that's good..." Professor Li seemed to know that he was too ugly just now, so he left after saying a few words.

As soon as Professor Li left, Bai Han grabbed Su Linjiang, and said with a smile on his face, "Look at that little hedgehog you just now, why, you don't want others to look down on you...husband?"

"No, I'm telling the truth." Su Linjiang said indifferently.

"Ha ha……"

Bai Han looked at the face of the other party who was pretending to be calm with a smile all over his face, "Why is this temper so annoying, his neck is red, and he said no..."

How good is the laboratory of Haishi University? From Bai Han’s point of view, it is almost the same as the laboratory in the Marvel movie. In addition to the ordinary trinocular microscope, there are also several electronic scanning microscopes here. Han's preliminary observations were studied.

"Put on your clothes." Su Linjiang handed over a white coat to Bai Han, and Bai Han said while changing the clothes: "When I do the experiment later, you write down all the experimental data."

"Ah."

“BCFS系统中高等微生物活性约占12~15%，A2/O系统中高等微生物活性约占14~17%，SBR硝化系统中高等微生物性约占9~11%……”

The three test tubes of seawater stock solution turned out to be more than enough after a whole night of experiments. Su Linjiang rubbed the center of his brows after writing down the last data, and checked his watch by the way, it was already 02:23.

Bai Han was exhausted after doing the experiment all night, but his physical fitness is not comparable to that of ordinary people. Looking at Su Linjiang's bloodshot eyes, he said distressedly: "You must be exhausted after staying with me all night. Alright, I'll take you back to rest."

"No, I'll just go back by myself, and you should go back quickly."

It's just that Bai Han insisted on sending him back this time. He knew that Su Linjiang didn't live on campus, so he couldn't let him go back by himself at this moment.

Seeing Bai Han's persistent expression, Su Linjiang no longer refused, and nodded: "Okay then!"

It was nearly three o'clock in the morning when we got home, Su Linjiang went to the balcony, saw Bai Han who was taking a taxi back from afar, his brows faintly frowned, and he turned around and closed the glass door after a while.

'Baihan, what kind of person are you? Why are there so many differences between your information and the real person? ’ Thinking of this, he took out the information about Bai Han’s investigation again. It described Bai Han’s simple life in the past [-] years. Similarly, it would definitely not say that Bai Han had at least the ability to save people and Contempt for the technical knowledge of the world.

In Su Linjiang's mind, he kept thinking about the person in the laboratory who was very handy with the experimental equipment and operated it smoothly.

"Bai Han!!!" Su Linjiang gritted his teeth and spit out his name, slowly closed his tired eyes, and the paper printed with Bai Han's information was slowly pinched and wrinkled...

There are not many materials that have been sorted out, plus some opinions written by Bai Han himself, there are only a dozen or so sheets of paper in total, but these are important materials for Bai Han to study the first machine.

The sewage processors currently on the market include sludge dewatering machines, centrifuges, microfiltration machines, aerators, and air flotation machines, but none of these machines can completely solve the problem of sewage, and even the cost of some machines is enough to make some small Businesses can't afford it.

Relying on 'Black Stone Skin Care', Bai Han also had some money on hand, so he immediately rented a factory building. As for the materials needed to make the machinery, he also prepared them. chant!

There is a lot of work to be done in this preparatory stage, and Bai Han still has things to do in the gang, so he often asks Su Linjiang for help. Who else can I turn to for help?"

Although Su Linjiang said coldly on the surface, "Who is in the same family as you, and don't call me 'daughter-in-law'!", but in fact, as long as Bai Han asked him, he never refused. I don't know if this is the so-called Duplicity? !

Many days have passed since the two people who met Hang Bang that day, Bai Han was hesitant to return the call, of course it was not because he thought he was decent, but because of the constant 'harassing text messages' on his mobile phone these days, Each of them came from the person named Taozi. After receiving so many text messages, Bai Han almost understood most of what this person was thinking.

The Hang Gang is just a small gang in Suzhou City. It was so unlucky that it got into trouble for some reason. The leader of the gang sent someone out to find rescuers. The person who was sent out was Tao Zi, and the one who was found was Bai Han. up.

How could this gangster not have a brother gang to take care of them on the road, and the Hangzhou gang is no exception. They also courted two or three local gangs in Sioux City on weekdays, but this time they got into trouble, and none of them were willing to help Yes, it's no wonder that the head of the Hangzhou Gang took such a bad idea to find a foreign gang to put out the fire. Of course, there was a reward for putting out the fire. The minimum reward was 5000 million. Taozi had already confessed to Bai Han in the text message.

In fact, such a small amount of money is really nothing to the Qinglong Gang. This Taozi seems to know this too, and keeps saying that as long as the Qinglong Gang takes action to protect the Hang Gang, even if it is to give half of the Hang Gang's territory to Qinglong after the incident Help is also good.

It seems that this Taozi's status in the Hangzhou Gang is not simple, and he made such a condition for such a big investment without the authorization of the leader of the gang.

This is indeed a tempting condition, after all, Bai Han also has the idea of ​​expanding the power of the Qinglong Gang, but this Hang Gang is only a small gang, so how much territory can there be, so Bai Han really has no idea about this.

What really made him agree was that the matter of Hang Bang was related to one person——Jing Jiao!

The old opponent of the Qinglong Gang, you have tried to destroy the Qinglong Gang several times, it's time to understand, then let's start with the Hangzhou Gang in Suzhou City!

"Brother Tao, he agreed, the leader of the Qinglong Gang agreed to see us!" Hou Liu said excitedly holding the phone, "What did you say!" Tao Zi snatched the phone, with tears in her eyes: "... ...Since he agreed to see us, he is probably willing to help us, Hang Bang, we are saved!"

After sending the text message, Bai Han's ears moved. He was in the hotel at the moment. As for the menacing footsteps outside, "Heh, has the Qinglong Gang finally arrived after waiting for so long?" '

When Big Ya and Leopard were dealt with back then, Bai Han waited for their leader to come to him. He wanted to see what the so-called 'Blue Dragon Gang' was like.

With plaster still on his neck, Da Ya limped to the door of the room, pointed at him fiercely, and said, "Brother Hei, that's right here. I watched that kid come in."

Brother Hei is called Da Lao Hei because of his dark skin, and his subordinates call him 'Brother Hei'. Big Tooth and Leopard are his subordinates. In the past few years, relying on the power of the Qinglong Gang in the deep sea, he has been in full swing. After a while, I heard that my brother was cheated, how could I not come to recover the debt.

"Bang bang..." The door of the hotel was kicked open by Da Lao Hei, and the brothers following him rushed into the room at once. Da Ya saw Bai Han leaning on the window sill smoking a cigarette at a glance, trembling. Looking at the flesh on his face: "Stinky boy, I caught you today!"

Bai Han babbled, this cigarette was exchanged in the system just now, and he said it was a "health cigarette". Anyway, he tried to smoke it without much exchange value. Those cigarettes are much better.

"Oh, that's really congratulations, but why didn't your good brother come with you?" Bai Han sneered.

"Damn brat, how dare you say that!!!" Big Tooth was very angry, Bai Han said his brother was Leopard, but Leopard was injured more severely than him, and he couldn't get out of bed until now.

"Brother, this brat is still arrogant up to now, you have to punish him, he doesn't care about our Qinglong gang at all!"

Da Lao Hei's face is also very ugly at the moment, his small eyeballs hidden under the slightly sunken eyelids are staring at Bai Han, and his voice is not angry and pretentious: "Boy, there are so many of us, aren't you afraid?"

"Afraid? Why should I be afraid?" Bai Han sneered, and then blatantly exhaled.

Bai Han's words were simply arrogant, but the big old black had no reason to believe that the young people in front of him were really not afraid of them, but he still said unwillingly: "You have to know that you are just one person, so many of us besieged You, you are not dead, you are disabled, so you are not afraid?"

"Hahaha, it turns out that the so-called Azure Dragon Gang is nothing more than that. They only have a lot of fat but no brains. Do you think the key to victory lies in the number of people?"

The corners of Da Lao Hei's eyes twitched, and the gangsters surrounding him also became agitated, and the way they looked at Bai Han was like eating people.

"Brother..." Da Ya gritted his teeth with resentment, the words have come to an end, there is no need to say more, let's start the fight, and prove everything with strength.

"Give it to me!" Da Laohei was usually flattered after all, how could he swallow his breath when he was ridiculed by such a brat.

For a moment, the whole guest room seemed to be shaking. All the furniture and electrical appliances were destroyed under the sticks. What Bai Han was waiting for was now.

"ah--"

"ah--"

Da Laohei brought a total of 20 brothers this time, and all of them had hidden weapons, either knives or sticks, and some had guns. I don’t know if it’s because of the narrow space. Bai Han was scratched in this fight. It was also this moment that made the alarm ring in his heart - his strength is not strong enough!

But dealing with these gangsters is not a problem. Apart from the knife, Bai Han didn't suffer any injuries, and he took the gun with one hand, "Since you guys like electric shocks so much, I'll let you enjoy them too."

"Ah...uh, uh, uh..."

"what……"

"Puff! Puff!!"

With one hand, Bai Han electrified people, and his figure constantly changed among the crowd. His sharp hand was fast, accurate, and ruthless. The whole room fell down, and when there were only three or two gangsters left, they were already dead. He didn't dare to do anything to Bai Han.

"Ah..." With a loud cry, these cowardly people slipped away.

In just a few minutes, only the big old man with a gloomy face was left in the aggressive group. Bai Han glanced at Da Ya who rolled his eyes from the electric shock, and sneered: "I said, I'm not afraid!"

After looking at Da Lao Hei lightly, Bai Han raised his foot and walked towards the door.

"Wait, little brother, what's your name... How about joining my gang?"

Bai Han raised his eyebrows unexpectedly, turned around and said, "What did you say?"

Da Laohei's originally gloomy face now had a signature smile, he touched his big belly and said: "You are very skilled, you have a great future in front of you if you join the Qinglong Gang, as long as you become famous, money, beauty, power It’s not all within reach.”

His words really moved Bai Han, not because of money or beauties, but because of this opportunity. Once he joins the big boss, he will be regarded as a member of the Qinglong Gang on the surface, and he is still at the basic level. It's in his favor, so that he won't find other ways to sneak into the grassroots of the Qinglong Gang, God help me!

"It's okay for me to join your gang, but I have a request."

"You said."

"I do everything according to my mood. It's okay to fight, but other than that, you can't interfere with anything I do."

"Deal!" Da Laohei smiled: "Then you are also a member of our Qinglong Gang now."

Bai Han hooked the corner of his mouth.

'Yeah, I can fucking write a paper on how to get into the Dragon Gang! '

After simply bandaging his arms, Bai Han put on a coat and went home first. It was still daytime and no one was at home, so he heaved a sigh of relief and went straight into his room, drew the curtains and locked the door, and finally opened the door. system.

The light blue screen was still shining as usual, but a lot of data on it had changed. Bai Han looked at the exchange value, and the bright 10000 made him feel hot. He didn't know how many things he could exchange for so much exchange value.

他立即搜索了有关武术的技能，系统界面上刷刷刷的显示出好几种技能兑换项目，华山剑法50；分筋错骨术20；泰拳20；形意拳50；跆拳道15；柔道15；空手道15；少林功夫50……

"Damn, there are so many." Bai Han couldn't help but screamed, mainly because these martial arts skills included not only the common ones on the market, but also Huashan swordsmanship and Shaolin Kungfu. All kinds of awesome moves in Jin Yong's martial arts movies flashed. If the system didn't deceive him, he might be able to possess superb kung fu like those heroes.

This is what every man is demanding, and Bai Han is no exception. He immediately selected all these skills to exchange, and suddenly several small icons appeared in the system warehouse.

'With so many skills, do I have to learn them one by one? Bai Han thought for a while: "The system, can we all choose to use it immediately?"

The system immediately gave a response: Of course, does the host need to use it with one click?

Bai Han immediately chose 'Yes'.

The screen switched in the blink of an eye, and Bai Han was already in the subspace. What was displayed in front of him was an antique painting style. There was no one in the entire subspace except wooden machines. He took a tentative step forward. The figures in ancient costumes slowly revealed their human form...

The kung fu on the body cannot be trained overnight, even though it was very hard in the subspace, Bai Han didn't say a word of "hardship". After going through so many things, Bai Han has transformed in essence. He is no longer the mediocre boy he used to be. Now he knows how to take the initiative and is willing to take responsibility for himself.

It was already night when Bai Han came out of the space, he looked at the time, his parents were about to get off work, and just thinking that tonight's meal would be ready by himself, the system suddenly issued a burst of electronic sound: "Beep— —The host’s martial arts achievement has reached Dzogchen, and the system will automatically enter the upgrade state.”

"..."

No matter how much Bai Han yelled 'open the system', the light blue system interface never appeared again. Although the system said it was being upgraded, this was the first time he experienced losing the system after owning it. Bai Han couldn't tell. How does he feel in his heart, but his mind is extremely clear, even if one day the system really disappears, he will still be him, a white man without a system can still live a wonderful life!

However, Bai Han frowned and thought about the last words of the system, "What is the martial arts achievement of great perfection?" '

Looking up, he saw himself in the mirror, and Bai Han felt his abdominal muscles smugly, "It's a pity that I don't want to be a model with this figure."

Even though he said so, he really didn't have the intention. When he touched some scars on his body, Bai Han immediately recalled the situation when he was practicing martial arts in the subspace. At this moment, he had mastered the Huashan sword technique, the division of tendons and bones, Muay Thai, Xingyi, Taekwondo, Judo, Karate, Shaolin Kungfu, it can be said that in this era, Bai Han's skills are already unrivaled.

"Could it be because I'm already invincible in martial arts, so the system will display the Great Perfection in martial arts?!" Thinking of this, Bai Han grinned. You're a scumbag, just make sure you are invincible all over the world.

He is indeed too kind!
