According to Liu Yuan's experience of staying here for many years, no one has applied for a patent for this thing, and this is the first one.

The patent system and regulations have been online for more than ten years, and most of them are not allowed to be preemptively registered due to historical reasons, and there are many innovations.

Rainstorm pear flower needles are not allowed to be preemptively registered, everyone can produce them, but the material formula is kept secret.

And such a large-scale improvement, which is a rainstorm pear flower needle, is simply a cannon.

Liu Yuan glanced at it a few times, and then went back to work with some reluctance.

Although he doesn't understand design. But after working here for a long time, you can see at a glance whether things are good or bad.

This item, which was transformed from the Rainstorm Pear Flower Needle, has long since fallen off its original form, and even its function has changed.

If this thing is patented, it will inevitably form a rush to buy in the future.

A wide range of attack capabilities, a salvo of 10,000 rainstorm pear flower needles, if you are pushed by a strong enough force, even a monster group can be cleaned up in an instant.

This is no less destructive than the scope of those powerful inheritances.

And after Xu Min looked at some places, he immediately saw some deficiencies.

He also saw that this was a novice design, otherwise many places could be improved and streamlined, so that hundreds of parts could be missing.

But he understands that the innovation of this design outweighs the shortcomings.

But no matter how many, even Xu Min didn't dare to draw conclusions too quickly.

After all, this weapon is too complicated, and he doesn't have the ability to see through it all now.

Xu Min asked: "Young people, are you interested in coming to my store, the treatment is easy to say." ”

Xu Min could see that this young man had a bright future. I can make such a design at a young age, but if I have experience in the future, I don't know what it will become.

Liu Yuan said on the side: "Master Xu, this is an old man, you are looking for the wrong person." ”

When Xu Min heard this, he said with pity: "It's Lao Yu, then forget it, I won't dig the corner." Okay, I'll go first. ”

Xu Min's design had been registered, and he shook his head with some regret and left.

Although things are good, they don't belong to him.

Liu Yuan finished registering Xu Min's design, immediately inquired about Huayun's, and after confirming that there was none, he also began to register and enter.

He looked at Hua Yun with some envy and smiled: "Mr. Hua, you are powerful enough." Two patents, how much does it cost a month just for licensing? ”

"I haven't decided to authorize it yet." After Liu Yuan finished registering, Hua Yun received the design drawings and prepared to leave.

Liu Yuan had already picked up the phone and told Jiang Zhun the general situation of this thing designed by Hua Yun.

At this time, Hua Yun had already left the outer heavens.

Because of the calculation of time, the parents are coming back soon.

Soon after Hua Yun returned home, his parents came back together.

The two of them bought a lot of vegetables in large bags, and when they saw Hua Yun, they were all surprised: "Xiaoyun, why did you come back so early today?" ”

"School is out for three days, so I'll be back early today." Hua Yun looked at his parents' big bags of things and said, "Mom, who is here today, I can't put it in the refrigerator when I buy such vegetables, right?" ”

Hua Jianfeng glared at Hua Yun and said, "Who else can come, of course it's Xiaoxiao." Brother Zhao and the two of them went out, and Xiaoxiao has been eating at our house for the past few days. Xiaoxiao came back at six o'clock in the evening, you go upstairs for me. ”

Hua Yun muttered in a low voice, "Just make a phone call." ”

"Smack!" Hua Jianfeng slapped Hua Yun on the back of the head and said, "Don't think that you kid will be proud of the girl who promised to be your girlfriend." You are lazy to be like this in the first few steps upstairs and downstairs, what will you do in the future? If you want to call, you can call it. ”

What the hell is this-

Hua Yun rubbed the shaved position. My father didn't touch him with a finger before.

Since Zhao Xiao came to his house, he has either been scolded or beaten, who is the biological one?

The two washed the vegetables and cooked, and when it was more than six o'clock, when the food was served on the table, they urged Hua Yun to call Zhao Xiao.

Hua Yun could only helplessly go upstairs and knock on the door of Zhao Xiao's house.

"Wait for me, wait for me." Zhao Xiao replied anxiously in the room.

Zhao Xiao knew who was coming, and there was even the sound of tripping things.

After a while, Zhao Xiao's breathing was a little urgent, and his little face was also red and pushed open the door.

Hua Yun's eyes lit up, and he felt that Zhao Xiao was particularly beautiful tonight. Dressed in a casual dress that fits well, the freshly washed hair still exudes a faint scent of shampoo, and the light evening makeup looks very simple and delicate.

Zhao Xiao also held two small bags in his hand and said, "This is what my parents left and asked me to give to my uncle and aunt." ”

"What to give, my parents don't like to accept other people's things the most." Hua Yun said.

Zhao Xiao was surprised: "Really? So, should I bring it with me? ”

"No, no. You treat it as your own home, and you give gifts when you eat, and you have a lot of foreign ways. ”

Hua Yun said, and had already begun to go downstairs.

Zhao Xiao listened from behind, his face turned even redder, he couldn't take the things in his hand, and he didn't know whether to put it down.

She followed Hua Yun downstairs.

Hua Jianfeng and the others were already waiting for the door.

When Zhao Xiao saw the two of them, he didn't know what to do, so he could only hand over the prepared gift and said, "Hello uncle and aunt, this is the gift that my parents asked me to bring to the two of you, a set of cosmetics, and two bottles of wine." ”

Hua Yun said: "Dad, Xiaoxiao doesn't know-"

Hua Yun also wanted to help Zhao Xiao explain, after all, when I saw others sending something to my parents before, the faces of the two of them were always long.

"Smack!" Hua Yun received another slap in the back of the head.

Hua Jianfeng pulled Hua Yun into the room, took the gift in Zhao Xiao's hand with a happy face, and said, "Xiaoxiao, your father still understands me, and knows that I have two sips of drink." ”

Xu Yulan also kindly pulled Zhao Xiao into the house and said, "Xiaoxiao, your cosmetics are good." Auntie is about to buy a set, and the previous ones have run out. ”

Hua Yun shut up and stopped talking.

Grandma, I have suffered in vain in the past few days.

Xu Yulan said: "Come, come, come into the house." Brother Zhao who specially asked today, what do you like to eat, it is all your favorite food. ”

Zhao Xiao was relieved by what Hua Jianfeng and the others said, and felt that he had not sent the wrong thing.

Hua Yun looked at Xin Dao from the side: You are naïve, and you are naïve. Not to mention that ginger is still old and spicy.

This meal was not fast, Xu Yulan kept giving Zhao Xiao vegetables and serving rice.

Zhao Xiao ate two bowls of rice, but he couldn't eat it, and when Xu Yulan wanted to serve another meal, he could only hold the rice bowl and say that he couldn't eat it.

"Hey, hey." Hua Yun looked at Zhao Xiao's expression from the side, and he could imagine what it was like to have a full stomach and still have to eat.

Because his grandfather did this when he was a child, he almost wanted to die.

As a result, as soon as Hua Yun's laughter came out, he was slapped in the back of the head again, and his face was almost in the bowl!

Hua Yun immediately lowered his head and went to pick up the rice, and didn't look up.

After eating, Hua Jianfeng and his wife cleaned up the table, and Zhao Xiao didn't let him help.

Xu Yulan just urged the two of them to go into the house to rest, and then study.

Huayun Evolution went directly to the store and began to process the parts of the rainstorm pear flower needle. Zhao Xiao went to An Ran to collect the things needed for the Nine Yin True Scripture. The two agreed to go home together at half-past eleven, so that the adults would not find out about the problems here.

As long as the maker masters the recipe, then with the modern technology modified furnace, the success rate is 100%.

All the Crafter has to do is assemble, design new weapons, and create recipes.

In terms of formulas, Huayun did not have time to create.

Design new weapons, and now transform the Rainstorm Pear Flower Needle in the main.

As for assembling weapons, he has now received hundreds of millions of large orders, which is enough for him to be busy for a while.

Earning 30 million a month, this figure was unimaginable before.

What's more, Hua Yun was assembling and dealing with the details of the rainstorm pear flower needles at the same time.
