Ye Xuan, this girl, started to do research, and she didn't care about other things, and her title has been changed for a while, but she looks completely unaware......

After all, what does it mean that he has changed his name? His original name was not called Chief, Leader was just a title, okay? But if you think about it carefully, within his civilization, the chance of the name 'Luo Ji' appearing from other people's mouths is really very small, so small that it is almost none, because no one dares to call him by his name at all.

For a while, Luo Ji was also depressed, and finally didn't bother to dwell on this question anymore, "You have to know that I am usually very busy at work, and I am really busy......"

"But I really need you to take a look at it for me right now, and then give me some advice." Ye Xuan blinked innocently at his big watery eyes.

"Ugh." Sighing, Luo Ji was completely with a 'I lost to you' expression, "Okay, okay, what problems are you encountering again?" ”

"Actually, it's like this......" Ye Xuan said as he quickly spread the design drawing in his hand on Luo Ji's desk, and at the same time didn't forget to compare it with the half-finished hand crossbow in his hand.

Unlike the two guards who seemed to be listening to a book from the sky, Luo Ji was obviously used to Ye Xuan's gushing way of speaking, coupled with his quick thinking, there was no pressure to digest.

Ye Xuan has been studying the hand crossbow for a long time, to be honest, it is only a few key small mechanisms in it that are far from completion, but these small mechanisms are the essence of the entire manufacturing process of the hand crossbow.

When Luo Ji returned to the real world before, although he had checked the structure of the crossbow, many things were another thing when they were actually operated.

If he could, Luo Ji really wanted to give Ye Xuan a silver-level crossbow design directly from the auction house, so that she could quickly make this crossbow.

But the problem is, he really can't do it, the reason is very simple, as one of the only few long-range troops in the entire cold weapon era, the crossbowman's hand crossbow design, the price soars to what extent you can imagine, Luo Ji's smile revealed a sense of poverty, for him who has more than 100,000 civilization points left in his hand, he really can't afford it......

Giving full play to his modern thinking, after seriously discussing this issue with Ye Xuan, Luo Ji appropriately changed the topic to another matter, "By the way, can you repair the siege tower when you asked someone to send it to you before?" ”

"Oh, that's already fixed." Ye Xuan replied nonchalantly, obviously not interested in the siege tower.

On the one hand, the siege tower itself has the original as a reference, in other words, according to her talent as an armor master, in the case of the original, as long as she dismantles the original, she can basically touch the entire structure, plus the structure and craftsmanship itself are not particularly complicated, and it is not too difficult to build another one later.

As for something that has been thoroughly studied by himself, Ye Xuan's interest will decline all the way, and finally become completely uninterested in that thing.

"Anyway, go back and get a copy of the design of the siege tower and give it to the Ordnance Manufacturing Department." Luo Ji reminded with a tired face, by the way, due to the reason of 'cartography', some design drawings with a high degree of completion have a chance to trigger the blessing of the effect.

Of course, it is difficult to draw high-level design drawings, Luo Ji thought that he had drawn very detailed designs when he was drawing armor and some bronze weapon designs before, but the system also gave a 'bronze level' judgment, and even more than a dozen of them did not even have a level, in other words, there was no effect blessing.

This can't help but make Luo Ji guess, will some professionals be allowed to paint, and the success rate will be higher? With this in mind, he asked Ye Xuan to try to draw the design drawings, and it turned out that each of the design drawings drawn by Ye Xuan was bronze-level.

Later, Luo Ji raised his requirements and asked Ye Xuan to draw more carefully, and then he got a black iron-level design drawing under Ye Xuan's resentful gaze......

However, that's all there is to it, no matter how hard Ye Xuan racked his brains, the design drawings he drew could not be upgraded to the level of 'silver', and sure enough, it was not so easy to get the silver-level design drawings.

But even so, this is enough to be called a huge discovery, and at the same time, Luo Ji also came up with a bold idea, that is, can these designs be thrown at auction and sold?

Facts have proved that the system did not give him a chance to exploit the loopholes, under the rules of the system, only the props that can be traded are the items opened in the treasure chest, and the design drawings drawn by himself are also design drawings, but there is no 'tradable' judgment.

This made Luo Ji a little depressed at that time, but then he thought about it, the way of the system doesn't work, so can't you just let Ye Qingxuan help resell it? !

At that moment, Luo Ji once again felt the horror of the 'business empire', but this self-produced and self-sold money-making plan was not successfully implemented in the end.

If you want to draw a high-level design drawing, you must have a professional with strong enough professional ability to draw it, so that you have a chance to draw a high-level design drawing with effect bonuses.

To put it bluntly, what Ye Xuan drew was a black iron-level design drawing, but Luo Ji took the black iron-level design drawing and asked an ordinary person to copy it, and the design drawing he got might not even be bronze-level.

In other words, he can't do mass production, after all, he can't let his professionals not work and go to the design drawings, right? Then he himself will be finished sooner or later!

"Got it." Ye Xuan obviously knows the importance of design drawings in her heart, although she has no interest in something that has been thoroughly studied, but in order to contribute to the development of civilization, she will still draw it in the end.

Facts have proved that if there is a mechanism for contributing points, Ye Xuan's contribution is estimated to be able to rank in the top three, which is also an important reason why the guards standing at the door dare not stop her at all.

"Don't forget about this, I'll ask the head of the Ordnance Manufacturing Department to come to you tomorrow to get the blueprints."

After discussing several issues with Ye Xuan about the structure of the organs, Luo Ji casually found a reason to ask her to go back and do the experiment by herself.

Looking up at the fiery red Mingjing Lake outside the window that was reflected by the setting sun, Luo Ji exhaled a long breath, and after briefly reviewing a few reports, and then after having dinner, he went to bed early, and at the end of the day, he was tired enough.

If you don't pay attention, it's time to add a change at the end of the month (someone with a confused sense of time), and the update is sent, thanks to the book friend 'Cyl903' for the monthly pass!
