Luo Ji, who was determined to clean up the group of hyenas, also did what he said, and in the next few days, he basically stayed in the ordnance department most of the time.

Although he doesn't have the talent of 'armor master', but that mind as a modern person is his biggest advantage, many little foxes are a little incomprehensible for a while The structure and problems of the parts, Luo Ji often only needs one sentence to make her suddenly enlightened, so that in the past few days, the little fox's loyalty to him has risen in a straight line, and at the same time, the research and development speed of bows and arrows and leather armor has also increased significantly.

A few days later, holding the longbow of the prototype work that he had just completed in his hand, Luo Ji was in a delicate mood, in the past few days, the failed products had been piled up into a hill in the corner of the camp tent of the Ordnance Department, when the first prototype longbow was completed, he was very excited, and when the second one was completed, he was also very excited, however, this has been nearly a hundred times, and all that is left in his heart now is subtlety and complexity, and there may be a trace of apprehension.

"Let's go, let's try it outside the camp!" Sighing heavily, Luo Ji got up with the longbow and walked outside, even the tribesmen in the camp were used to their comings and goings in the past few days, and then continued to do their own work.

Test the effect of the weapon, this is probably the only time that the little fox will leave the camp of the ordnance department in addition to eating and sleeping, although she has experienced nearly a hundred failures, but she is not discouraged, holding the bow and arrow design that has been revised and modified many times, and the little face followed behind Luo Ji with a little nervousness.

It's an experiment, but there's actually no high-level process, to put it bluntly, it's just to find a place to shoot an arrow and try it.

Walking to a vacant space outside the camp, Luo Ji held a longbow, took two deep breaths, calmed his emotions, and then took an arrow from the members of the Ordnance Department on the side, ready to start the test.

To tell the truth, this arrow is very rough and even a little inferior, but there is no way, the conditions are limited, they can't get a large number of feathers at the end of the arrow for the time being, and the metal arrow is even more helpless, so it is simply sharpened a straight wooden stick to be used as an arrow.

But the lethality is still no problem, after all, there is no armor and armor in this era, if it is just inferior leather armor, according to the sharpness of the arrow, it can still penetrate, of course, the focus is on the longbow part.

During this period of time, Luo Ji, who had tried to shoot too many times, was already very skilled in the whole bow and arrow, and he didn't dare to pull too hard at once, Luo Ji controlled his strength, and pulled the bowstring woven from two beast tendons little by little.

Looking at the bowstring that was tightening little by little and constantly stretching, Luo Ji's originally calm mood became a little nervous uncontrollably, his heart was beating so fast, he didn't expect that he would fail so many times in researching a bow and arrow.

The toughness of the bow made this time is no problem, looking at the longbow that has been completely opened, Luo Ji took a deep breath, as if he wanted to test the limit of the bow, the hand holding the bowstring actually increased the strength a little more, and forcibly pulled the bowstring that had been pulled to the full moon by another point.

Then, I saw him loosen his fingers, accompanied by the sharp arrows that flew out, and the prompt sound of the system sounded in Luo Ji's mind......

System Prompt: Congratulations to the player 'Luo Ji' for successfully crafting the 'Bow and Arrow'.

System Prompt: Congratulations to the player 'Luo Ji' for successfully unlocking the military item 'Archery'.

Two system prompts in succession, so that Luo Ji, who was originally nervous, completely fell into a burst of ecstasy, no need to say anything at all, looking at the parabola drawn by the arrow in the air, the ecstasy that swept like a tsunami at that moment almost made everyone in the Ordnance Department feel dizzy, every face turned red because of the excitement, and then one by one they danced and carnivaled! Many of them yelled like fools, venting their emotions in this way, "It's a success!" We made it!! Hahaha!! ”

After a burst of almost crazy cheers and celebrations, Luo Ji took two deep breaths, trying to calm his emotions again, but the corners of his obviously grinning mouth couldn't be restrained.

However, he still pretended to be serious, "Okay, okay, everyone calm down, this is just a trial work, there are still many things that need to be improved, give me a good job, tonight, add two more fish to the pot of the Ordnance Department!" ”

Not surprisingly, Luo Ji's generous reward attracted a burst of cheers again, and even many people had already shouted 'Long live the leader', and Luo Ji himself was a little embarrassed when he heard it, and hurriedly laughed and scolded and urged these people to do their business.

A qualified longbow, in addition to being able to shoot lethal arrows, durability is obviously very important, of course, in addition, range, accuracy and stability are also very important, so in order to confirm these data, it is obviously not enough to shoot an arrow.

After everyone was ready to take their positions, Luo Ji bent the bow and arrows again, and launched their follow-up experiments, which proved that after learning the lessons of so many failures, the longbow they made this time was of quite good quality, the bow body was full of toughness, and the bowstring part was strong enough, and ten arrows were fired in a row without any problems.

Just when Luo Ji was about to shoot a few more arrows and finish collecting the data, there was a sudden obvious pain in the hand that was responsible for drawing the bow, which made his brows furrow uncontrollably.

"Hiss-" Hiss-" sighed lightly, Luo Ji looked down, only to see that his finger was actually strangled by the bowstring with a deep blood mark, counting the nearly 100 failed tests in the past, Luo Ji shot at least 500 arrows in the past few days, and he didn't pay much attention to it before, and when he came back to his senses, his finger was like this......

Feeling the pain in his fingers, Luo Ji patted his head, "I'm careless." ”

Then his mind turned, and he hurriedly asked someone to find a relatively thick soft animal skin, and then made a few things similar to 'finger guards' and put them on his fingers.

He patronized the study of bows and arrows before, but he forgot about other small equipment that archers need, which was really a miscalculation, but the things he wrote down some time ago were too many and too miscellaneous, and he had too many things in his head, and occasionally he couldn't remember one or two things, so it was helpless.

After putting on the finger guard, Luo Ji moved his fingers, which was quite flexible, and then tried to shoot a few arrows, which was really a lot more comfortable, and then he shot more than a dozen arrows, and finally collected all the data that needed to be collected.
