In the school, Su Wu had already taken off his glasses, put on a wide school uniform, and his hair became oily again, although he washed his hair every day and used shampoo, but what could Su Wu do, he could only complain about the school's faucet.

Three days passed quickly, even if some people had been constantly provoking, Su Wu looked at each other and smiled, he didn't care, but it wasn't time to care. During this period, Su Wu was naturally not idle, and under the pressure of countless pressures, he consulted a large number of materials, literature, as well as the patent application process and some conditions required.

Su Wu was very glad that he had just turned eighteen years old, otherwise he would have been subject to so many restrictions that he didn't want to.

As soon as school was out of school on the afternoon of the third day, Su Wu came to the underground black market with his schoolbag on his back.

However, before he arrived at the door of Lei Jun's store, Su Wu saw that several students from the same school were dragged to a dark place by several social gangsters.

Su Wu inadvertently swept the knife in the thug's hand, and he was stunned.

At this time, Su Wu was struggling slightly, and it was dangerous for him to help, but if he didn't help, Su Wu was very entangled in his heart.

Coming to the door of Lei Jun's store, Lei Jun's sledgehammer was waving as always.

"Uncle Lei, do me a favor. Su Wu said.

"What, do you want me to help you save your classmates?" Lei Jun is a martial artist, and the sensitivity of the six gods is not much stronger than Su Wu, so he naturally saw it early in the morning, and he also knew some thoughts in Su Wu's heart.

However, this time Su Wu did not coquettish or smirk, but looked at Lei Jun very seriously. He knew that Lei Jun was also a gangster in the past, and he had done evil things, so he was not very sure in his heart whether Lei Jun would help a few students to teach people who were once like him.

Moreover, he didn't know who those people were, Lei Jun's shot, would it affect the business of the store?

Su Wu is naturally not a child, it is impossible not to think of this, but seeing that his classmates in the same school are about to be 'robbed', he always feels bad in his heart.

"Tell Xiaoping to go with you. Go and go back, your stuff is just ready. Come back and watch together. Also, there are thousands of trivial matters in the world, can you manage them alone?" Lei Jun is still constantly striking iron.

"I see that I naturally have to take care of it, today it is others who are bullying, no one cares, what if it is you tomorrow? Although I don't have the strength, I have friends!" After speaking, Su Wu walked towards the antique shop, leaving Lei Jun stunned on the side.

On the way, Su Wu's heart was heavy, Xiaoping? Can Xiaoping beat those gangsters? However, Su Wu still ran to the antique store and called Ye Ping.

Inside the Black Market Trail.

"Boy, don't say anything, don't care who your backer is, if you don't take out your things today, don't want to leave!" a thug threatened with a wall in one hand and a knife in the other, standing in front of one of the students' abdomen.

The other two students had horror and uneasiness in their eyes.

"You think about it, this thing belongs to my eldest brother, and my eldest brother belongs to the Black Dragon Gang......!

Syllable!

Before the student could finish speaking, he was slapped by the thug with the knife, hard and fast. The corners of the boy's mouth turned scarlet.

"Noise! I don't have time to talk nonsense with you! If you don't hand it over, you've thought about it······" The thug swept the knife in his hand and looked at the boy menacingly.

When the young man saw the knife in the gangster's hand, his eyes also showed fear, but he still stared at the gangster a little unwillingly. At this time, the two students next to him persuaded the teenager to hand over the things. It's a black market here, maybe it's all in vain if you die, and the police almost don't come much, and they don't necessarily care if they come, besides, can people let the police find evidence?

"Hey, scumbag over there, look at Dad!" At this moment, an extremely arrogant voice came.

As the thug turned around, he saw a black shadow flash, and immediately, the thug completed a 360-degree rotation directly in the air, and several teeth were knocked to the ground.

"You're not qualified to see Dad!"

Ye Ping moved his wrist and looked at Su Wu helplessly, these words were not what he said. However, the young man who was blackmailed by the gangsters heard this, and he felt very relieved!

"Damn!" After wiping the blood from his mouth, the beaten thug stared at Ye Ping and Su Wu with red eyes, and it looked like tears of pain were about to come out.

The corners of Su Wu's mouth curved slightly, and he glanced at the gangsters with disdain, and then his eyes stopped at the three classmates from the same school.

"You guys, come with me. Xiaoping, get them and teach these scum of society how to behave. Su Wu said calmly, and what he said was simply arrogant to a certain point.

The gangster was so angry that he was holding back a ball of blood in his heart, but he also condensed in his heart, and looked at Su Wu incredulously, although Ye Ping just now was a sneak attack, but his strength was not weak, but it seemed that this guy in front of him seemed to be a little more powerful. It's just ······ This is fucking too thin, isn't it?

Su Wu saw that the classmates were still stunned, and snorted angrily.

"Let's go!" the leading young man let out a low shout, and the three of them hurriedly followed behind Su Wu. The other two gangsters wanted to stop them, but they were blocked back by Ye Ping.

Su Wu led the three of them to the staircase and went to the used bookstore.

"Why don't you come home here?" Su Wu said to the young man who had been slapped, his eyes indifferent.

The young man looked at Su Wu, and looked at Su Wu's body, which was simply a weak scum with a combat strength of only five, but people helped him, so he naturally had to be polite, so he said slowly: "Buy something." Thank you, which school are you from?"

Su Wu chuckled and said, "You're welcome, I'm from the same school as you." Are you a freshman or sophomore in high school?"

Hearing that it was from a school, the teenager relaxed a little more, and said with a smile: "Class 26, Wang Chao." What about you?"

"High thirty-one class, Su Wu. Su Wu introduced himself. "Okay, you should have bought everything, right? This is not the place for you to come, so let's go back. ”

Wang Chao nodded knowingly, looked at the two classmates beside him, and then said to Su Wu: "Don't thank you for your kindness, if the senior needs it, just come to me." ”

Su Wu smiled softly, nodded, and said goodbye again, Su Wu remembered Ye Ping, was a little worried, and quickly returned to the underground black market.

Although Ye Ping said that he could handle it, and he also knew that Xiao Wu was a practitioner and had stronger combat effectiveness than the average middle-aged man, Su Wu was still not at ease.

"Brother Xiaowu, you came, and they were all beaten away by me. Ye Ping grinned at Su Wu.

Su Wu touched Ye Ping's body, and it seemed that he was indeed fine, so he simply breathed a sigh of relief.

"I'm sorry for the trouble. Su Wu said very unpleasantly, he knew that maybe those guys wouldn't give up.

Ye Ping smiled slightly: "It's okay, Brother Xiaowu." Let's go, Uncle Lei said that the environmental protection bucket is ready, let's go and have a look!" Su Wu listened, and immediately put aside a series of troubles.

For Su Wu now, this invention is simply his lifeline! If the patent application is successful, he can buy more than 100,000 yuan casually, and he will be a big family at that time!

"Uncle Lei, I'm back. Su Wu and Ye Ping came to Lei Jun's shop with joy.

Lei Jun snorted lightly, then squatted down and took out an iron bucket from behind the counter that was much larger than an ordinary trash can.

Boom!

Even though Lei Jun had put down the iron bucket very lightly, the sound of the iron bucket colliding with the ground was still very loud.

At this time, Qin Han and his wife and Ye Ting also arrived.

"Let's try it?" Lei Jun said to Su Wu, handing over a bucket of ordinary garbage.

Su Wu took the trash can, poured all the garbage in the trash can into the iron bucket, closed the lid, activated the automatic button, and after a while, the iron bucket rang slightly.

The people around the bucket held their breath and stared intently at the bucket.

After about ten minutes, the iron bucket was silent, and Su Wu opened the iron bucket.

Everyone looked into the iron bucket in unison, and the garbage that should have been inside was nowhere to be found at this time. Among the thirty-two small tubes next to it, there were some liquids and solids in several small tubes, which seemed to be separated impurities.

"Okay! It's done! Let's see how the distributor is!" Ye Ting was the first to cheer, because the most in this was his and Su Wu's hard work, and as for Lei Jun, at most he only took the title of production.

Su Wu immediately checked the dispenser, and the liquid and solid in it were evenly and distinctly divided, and there were at least seven or eight different substances.

When all the items were checked, everyone smiled happily.

"Uncle Ye, you now sort out the drawings, the regulations are clear, and then go to the printing shop to print a manual. Uncle Qin, you can help write a patent application, and you can find it by searching on the Internet. I'm coloring with Xiaoping now. Su Wu made sufficient preparations for the patent application and quickly arranged everyone's work.

In just an hour, everyone completed the task, Lei Jun closed the storefront, and prepared to go to the patent office with Su Wu and the environmental protection bucket.

"Be careful on the road. Qin Han and his wife and the Ye family said with a smile.

Soon, the two arrived at the door of the patent office.

Su Wu and Lei Jun glanced at each other, then they both looked at each other and smiled, Lei Jun picked up the environmental protection bucket and walked into the patent office with Su Wu.

At this time, it was almost eight o'clock, and the patent office closed at nine o'clock. Therefore, Su Wu did not dare to delay in the slightest.

"Hello, do you need any help?" asked the front desk lady very sweetly.

"Hello, young lady, I want to apply for a patent. Expedited. Su Wu smiled at the young lady at the front desk.

"The little mouth is so sweet. Let's fill in the information first. There is also 3,000 yuan to prepare. The young lady at the front desk handed Su Wu a data card, and Su Wu quickly filled in all the information.

"Well, a practical invention. Urgent... Belch... It just so happens that Professor Yan is here today, little brother, you are so lucky. The young lady at the front desk said.

Su Wu listened to the Shinto Dao, and he didn't know what the young lady was talking about, but soon, the young lady called another young lady and asked her to lead Su Wu and the others to an office.

"Professor Yan. The young lady said respectfully to an old man.

The old man replied lightly, then looked at Su Wu and Lei Jun quickly, and then shifted his gaze to the environmental protection bucket.

"What is this?" asked Professor Yan, pointing to the bucket.

Su Wu was shocked in his heart, because he had consulted a lot of information, so he knew that many patents were examined by professors, especially the application for utility patents, which was even stricter. However, Su Wu still used the most introductory language to introduce the use of environmentally friendly barrels.

"You invented it?" Professor Yan looked at Su Wu, and there was a subtle light in his eyes.

"It was my idea, and I worked on it with my family. Su Wu said, in fact, there was nothing wrong with saying that he invented it himself, because Ye Lao and the others only helped him speed up the progress of completion.

Professor Yan nodded, and Su Wu cleverly handed over the instructions and patent application to Professor Yan.

Professor Yan looked at the manual carefully and nodded several times. Su Wu and Lei Jun secretly looked at each other, and they both saw joy in each other's eyes.

"Mind if I try it?" Professor Yan asked at Su Wu.

"Of course there is no problem!" Su Wu hurriedly replied respectfully.

Then, Professor Yan hesitated for a while, but still put a stone emitting blue light in his hand into the environmental protection bucket.

"Spirit Stone?" Lei Jun said softly, slightly surprised.

Naturally, it is not because of the spirit stone, although the spirit stone is slightly more expensive, the market price is 1,000 yuan a catty, but Lei Jun also has some. However, he was a little puzzled, why did Professor Yan put the spirit stone in the environmental protection bucket?

Soon, the eco-friendly bucket began to work.

When Professor Yan saw a tube with blue liquid, his eyes widened.

"Miracle! I didn't expect that what no one else could do, you did it by a little guy! ha······"

But Su Wu on the side was blindfolded, what is going on? It seems that something big is going to happen.

"Little one, you go to the reception room and rest for a while. I'll take care of a little bit and I'll let you know. Fluttershy, say hello to the little brother and this ······"

"Under the Thunder Army. ”

"And this Mr. Ray. Professor Yan nodded slightly at Lei Jun.

Then, Su Wu and Lei Jun were taken to the reception room, where there was almost everything, and at first glance it was a high-level reception room.

"Uncle Lei, we?" Su Wu was terrified in his heart, what was this going on, he felt as if he had won a million-dollar jackpot.

Lei Jun also looked at Su Wu in confusion, you ask me, how do I know?

"Let's wait and see what happens. Lei Jun said helplessly, looking at Su Wu, he shook his head in his heart, could it be that this kid really made some very powerful invention?

Lei Jun pondered why Professor Yan put the spirit stone in the environmental protection bucket.

Syllable!

Lei Jun patted the table next to him, obviously thinking of something, and suddenly glanced at Su Wu with a strange look in his eyes!
