Of course, "Huaifeng" still has a lot of problems.

Compared with the classic design of the earth copied by the "Mauser" because of its familiarity with the structure, this "Huaifeng" sniper rifle is almost entirely a new type of weapon designed and created by Xia Yu according to his own ideas and the knowledge of the source array structure and mechanism technique that he has learned in the past few months.

Because he didn't feel too sorry for Yuan Jing, he tried more than twenty shots in one go, and soon found some problems.

For example, the jaw bone fragment of a triangular hairy calf used as a "gun tongue" to play an energy conversion effect is weaker, and it needs to be replaced with a better one when you turn around;

After rotation, the pull bolt is somewhat frustrated, and the relevant parts must be polished to improve the accuracy;

In addition, there is still a bit of a problem with the stability of the shot, you can consider increasing the barrel rifling to 7, and a new step to increase the rotation speed of the warhead to ensure flight stability.

There is also the control, although my perception is fine enough, but I still need to adapt to the control rhythm of this new source box, and I need to practice.

With Xia Yu's current perception, I am afraid that if he fires four shots in a row and exhausts this 2-star source crystal, his perception will be quite tired, and he needs to take a break and adjust.

However, after the amethyst crystal is in hand, it should be able to solve this problem, and with the addition of prismatic dust stone, I believe that this new source box can go further.

At this point, "Huaifeng" has been considered a success.

"Brother Liang Feng, I will take care of your family, you go well!" Looking at the turbulent river, Xia Yu's mind was extremely calm, and his eyes gradually became firm.

............

The second floor of Tianxin Club is overcrowded again.

This is the third time they have held an "intermediate apprenticeship exchange meeting", and the number of people is even larger than the first.

Because of its effectiveness in enhancing reputation, even other large shops are already imitating it.

But the most lively is still Tianxin here.

Early in the morning, Xia Yu came to the third-floor club, and after listening to the lecture of a three-star mechanic, he quickly entered the free reward question session.

Suddenly, the hall was crowded, and the questions on the big screen above their heads were swiped down like a waterfall, and new questions were raised almost every second.

It didn't take long for the sound of "Didi", which had been verified to be correct, kept coming back to mind at the venue, and the atmosphere quickly became extremely hot.

Apparently everyone is familiar with the rules, and the efficiency has become faster.

"Xia Yu, I knew you would come!" Lan Xi seemed to trot all the way to find Xia Yu who was on the sidelines, and gasped: "Manager Chen has something to look for you, just over there!"

"Looking for me again?" Xia Yu was a little puzzled, but still nodded and followed her.

Chen Mingde is still the host today, but he just finished his busy time and had nothing to do, when he saw Xia Yu coming over, he directly pulled him to the rest area and sat down, and said straight to the point: "I heard Lanxi say, do you need amethyst and prismatic dust stone? 500 grams each?"

Xia Yu nodded: "Yes, but your shop doesn't sell it directly!"

"No way, these two special materials are treasures, and a little more can be directly auctioned, just exchange points, there are too many Tianxin doesn't have them." Chen Mingde glanced at him, leaned closer and whispered, "My brother is developing a new source box?"

"That's right. ”

"How does it compare to Wedge 2?"

"It can be regarded as a transformation on its basis," Xia Yu said that he stopped there, "The specific inconvenience has been revealed, and I invite my brother Haihan." ”

"Where is it, my brother is really extraordinary!" Chen Mingde sighed, and suddenly changed his words: "I don't know if this new source box, or the new organ, can be handed over to Tianxin as an agent?

Xia Yu shook his head and said seriously: "Thank you, brother, but this mechanism is a little special, I won't take it out for sale in a short time, Brother Chen, forgive me!"

"If we work together, those two materials are not a problem at all, even the rarer ones you can try. "Chen Mingde is not too dead.

Changing to other middle-level apprentices, he was afraid that he would not even be able to say hello, but Xia Yu's previous performance was too amazing, and he did business, of course, he did not hesitate to put down his body.

"It's really not good," Xia Yu shook his head again, knowing that Chen Mingde really thought about him, and decided to make up a reason: "This mechanism was customized by me for a friend, and it will definitely not appear in the market and will not affect Tianxin's business." ”

Chen Mingde understood: "That's it, that's really a pity!"

The exchange meeting was in full swing, Xia Yu didn't say much to him, turned around and left.

The conversation between the two made Lan Xi dumbfounded.

Steward Chen actually took the initiative to ask Xia Yu for cooperation!

This completely subverted her perception of the middle-level apprentice, and she stood in place in a daze, when suddenly Chen Mingde called her: "Lanxi?"

"Ah, Steward Chen!"

Chen Mingde looked at Xia Yu's back when he walked into the crowd, and whispered, "You go and check the inventory of those two materials...... If Xia Yu is in a hurry, I want to find a way to see if I can give it to him in advance! But don't tell him yet, I can't guarantee it now. ”

"Ahh

Lan Xi's brain was completely disconnected, and the doubts and shocks in his heart became heavier.

Xia Yu returned to the hall, and the hall was still noisy at this time, like a tavern, but everyone's faces showed excitement.

He found a fairly spacious place to stand, looked at the bounty questions that kept brushing on the light curtain in front of him, breathed a sigh of relief, opened his connector and began to browse.

These questions ...... It doesn't seem to be difficult!

Article 1......

Article 2......

Xia Yu quickly got into the groove.

I saw that he sometimes frowned and pondered, sometimes lowered his head and entered quickly on the connector, and soon entered a state of complete forgetfulness.

Lan Xi was fine, curiosity rose, and he quietly stood behind Xia Yu.

Soon, her expression became incomparably more exciting.

Xia Yu's speed of answering questions ......

It's so fast!

............

Soon, an hour and a half passed, and Xia Yu's speed was fast, and he had already answered more than 30 questions.

There are 18 that have been confirmed to be correct, and the number of points has risen to 120 points.

But it seems, he didn't seem to stop for a moment.

Staring intently at the light curtain, his brain was running rapidly, and at the same time, the sensing cyclone was also mobilized, and from time to time he was building a source array structure.

To be able to be raised with a bounty, every question here is not simple.

However, Xia Yu's theoretical knowledge of the mechanism has gradually been completed a lot, and he has a lot of experience in making source boxes.

Especially in the past two months, Xia Yu has been eagerly studying various different 2-star source boxes, as well as some guidance from Master Qu and Luan Zijin.

Complementing the basics, combined with the ability to perceive "modeling" and deduction, he didn't know how much effort he spent and how many problems he overcame in the process of his own research.

And these hard work has ushered in a small outbreak today.

In addition, in addition to the theory of the structure of the source array and the production of the source box, Xia Yu has gradually figured out the world's popular mechanical structure system in the past few months, and various mechanical theories inherited from earth science education have gradually begun to play a role.

Even if it can't be applied directly, the logical thinking ability cultivated during the Earth period has a lot of utility.

Soon, another hour passed.

Xia Yu's mind gradually showed a feeling of exhaustion.

Looking down, his score has risen to 310 points, obviously the previous answer has been confirmed to be correct again.
