After a long absence, he went to the Ordnance Research Department, the Ordnance Forging Department, he had just been there before, but the problem was that the two departments of the Ordnance Department and the Research Department had already been placed separately.

The main reason is that research needs a relatively quiet environment, and the movement of forging weapons on the side of the forging department is too big, which has caused interference to the research department, and under Ye Xuan's protest, Luo Ji moved the research department to a relatively secluded location.

The level of chaos on the research department's side will surprise Luo Ji every time, all kinds of materials and suspected materials are piled up everywhere, and there are few places to stay.

After all, it is a department that requires high IQ and high talent, so the number of department members is not large, including Ye Xuan, the head of the research department, there are less than ten people, and after Luo Ji came in, no one paid attention to him at all, or no one noticed that he came in at all, and they were all immersed in studying the things in hand.

Luo Ji also deliberately lightened his steps, and walked towards Ye Xuan's office, as soon as he entered the door, Luo Ji, who originally thought that it was already chaotic enough, was instantly refreshed.

The degree of chaos in Ye Xuan's office is already out of a realm, Luo Ji asked himself not to touch those things that are piled up in the east and west, and he doesn't know what they are, because when he was working like crazy before, the work documents on the desk were also messed up like this, but in fact, this kind of chaos is a regular mess, and the owner of these things can easily find where something is, once it is messed up, it is really messy.

After getting closer, Luo Ji's face couldn't help but show a little curiosity, after the three-bow bed crossbow had been successfully studied, there was no new ordnance and equipment to study for the time being, and the members of the entire department had begun their own free research, under this premise, Luo Ji was very curious that Ye Xuan would study something.

As if sensing someone approaching, he mistook Luo Ji for a member of the research department, Ye Xuan said without raising his head, "Bring me the design drawing on the table on the left." ”

Hearing this, Luo Ji subconsciously fell his gaze to the design drawing on the table, and then, his whole expression was stunned, "This is ......"

"Why are you moving so slowly?" Ye Xuan, who had been waiting for a while, seemed to be a little impatient, she couldn't help but look up at the design drawings that had been immersed in the design drawings, and then, looking at Luo Ji who was standing there, she couldn't help but be stunned, obviously she didn't expect that the person who came in would be the leader, and then she seemed to remember something, and her face immediately showed a touch of joy, "Leader, you came just in time, hurry up and help me take a look at this ......"

As he spoke, together with the design drawings he was drawing, Ye Xuan hurriedly stuffed all the design drawings on the table into Luo Ji's hands.

Unlike most of the people in this tribe, Ye Xuan's attitude towards him as a leader is not the kind of respectful, it has always been quite casual, of course, there is no problem with loyalty, it has reached ninety-seven points.

Maybe in front of the identity of the 'leader', Ye Xuan regarded him more as a good friend who had a common topic with her, after all, in this tribe, except for Luo Ji, a modern person, there was no second person who could keep up with the thinking mode of this armor master.

In this regard, Luo Ji didn't mind much, looking at the design drawings in his hand, to be honest, the drawings were very rough and simple, but Luo Ji recognized the things on them......

"Is this a crossbow?"

"Hand crossbow?" With this word in his mouth, Ye Xuan's eyes suddenly lit up, "This name is good, write it down, write it down......"

Directly grabbed the charcoal pen in hand, and wrote the words 'hand crossbow' on the desktop of the wooden table, and then saw her look at Luo Ji standing there with an excited face, "It's worthy of being the leader, just by looking at the design drawing, I know what I'm going to do!" I've been thinking about the three-bow bed crossbow when I was researching it before, although the three-bow bed crossbow is amazingly destructive, but it is too cumbersome, it is cumbersome to transport, and it also requires a lot of people to operate, except for siege warfare and defense warfare, I am afraid that it will not be used at all in other occasions, so I was thinking if I could make a smaller version of it to make it more flexible, and it is best that each soldier can use it alone, so that it can be applied to any battlefield......"

Looking at Ye Xuan, who was gushing as soon as he opened his mouth, Luo Ji couldn't help but be a little shocked in his heart, he was a modern person, and it was not uncommon for him to know such a thing as a hand crossbow, but Ye Xuan, as a person from ancient times, could actually think of a hand crossbow that was almost at the other extreme from such a bulky and huge three-bow bed crossbow? This brain is a little too powerful.

"Chief, what do you think of my thoughts?"

"Ahem, ahem!" Luo Ji, who was in a state of shock, suddenly came back to his senses when he was suddenly asked, and then immediately nodded seriously, "I think it's okay." ”

After getting Luo Ji's affirmation, Ye Xuan couldn't help but feel more confident, and then hurriedly flipped through the design drawings, "But I encountered some trouble during the research, if you want to reduce the three-bow bed crossbow to the level of a hand crossbow, I'm afraid the overall structure will have to be greatly modified......"

The next Ye Xuan unexpectedly smashed a lot of questions that others couldn't answer, and Luo Ji, who couldn't escape in time, could only discuss with her for a while.

The hand crossbow was something he hadn't studied seriously before, because the smaller and more precise the thing, the more difficult it was to manufacture, Luo Ji felt that their tribe might not be able to make it in a short time, so the plan to set up a 'crossbowman' was placed quite later, but he didn't expect that Ye Xuan would actually propose the weapon of the 'hand crossbow' in advance.

But fortunately, the current Ye Xuan also thought of such a concept, many important details have not been solved yet, Luo Ji picked a few places he knew and mentioned them, Ye Xuan on the side suddenly had a feeling of sudden realization, "So that's the case!" It's worthy of the leader, what I didn't think about before, you can figure it out at once! ”

Luo Ji was a little embarrassed when he heard this, and said secretly in his heart, "It's you who is really powerful, if I wasn't a modern person, I'm afraid I wouldn't even be able to answer a word in the face of these questions, right?" ”

Thinking of this, Luo Ji suddenly realized that he couldn't stay here longer, the bit of ink in his stomach had been emptied, if Ye Xuan threw a few more questions, he would probably be dumbfounded, "Ahem!" Ye Xuan, I have other work to deal with, so you can study it yourself. ”

Slipped away......
