"I said, this is my workshop, can I not come in without permission?" Zheng Yichen looked at the woman next to him who was watching the party, as if he didn't hear Zheng Yichen's words, he just summoned a projection of a demon soldier summoning book and put it in front of him.

"......" Looking at this thing, the corners of Zheng Yichen's eyes jumped slightly, the witch is also interested in the magic soldier summoning book? Even though Zheng Yichen can get a high-level demon soldier now, that thing is still nothing in the witch's eyes, right?

"I just want to know, when will I be able to add some magic soldiers suitable for witches?"

"A ...... fit for a witch Scold. Zheng Yichen pulled a face and smiled inexplicably, "What are you kidding, the witch's abilities are so strange, how can I be capable...... Gan!"

Seeing Dan Marina's smile, Zheng Yichen's face darkened completely, "I finally know why Qin said that so many people hate you." ”

"I'm just a little more curious. Dan Marina smiled.

"Even if you are curious, after so long, you should be satisfied, right?" Zheng Yichen asked rhetorically, because of this girl, Zheng Yichen has not made any substantial progress in strengthening his strength during this time.

"Don't you know that there are some things that the more you cover up, the more you want people to know?"

Zheng Yichen smiled without itching, although he is still a little tender compared to the old monsters, but now compared to himself who originally crossed into the other world, it is much better, other aspects dare not guarantee it completely, but in terms of identity, it will not be directly exposed, seeing that Dan Marina is determined not to take the initiative to leave her workshop, Zheng Yichen also gave up the idea of expelling her.

Took out the backlog of a week's schedule, the time has been delayed for so long, he is about to start rushing to work, there is no shortage of materials for the time being, after all, he cooperates with Qin, and the relationship network of a witch whose identity has not been revealed is still extremely large, although Zheng Yichen has a large demand for materials, but he is now a person after all, compared to the resources required by those forces, there is still no comparison.

No matter how much he eats resources alone, he can't eat resources for a group of people.

Research is of no race, even goblins...... It's really important to do research, and the resources consumed are not much worse than those consumed by dragons, but Zheng Yichen is standing on the shoulders of giants because of his knowledge of the earth, and although the use of resources is very large when researching, it eliminates most of your wasteful steps and makes a higher level of use of resources!

Ignoring Dan Marina on the side, Zheng Yichen spread a blank piece of paper on the workbench, picked up a pen and thought for a while, and began to draw a new structural map.

Before the crossing, Zheng Yichen was very idle on Earth...... When it's okay, I'll search for something on the Internet.,Over time, I've accumulated a lot of 'miscellaneous' knowledge.,In the past, the power was not enough.,These things are basically forgotten after seeing them.,Now the power has increased.,The memory has skyrocketed.,Those who have seen but are hidden in the deep memory of the knowledge can all be searched......

There are many structural drawings of firearms, which may not be absolutely accurate, but as long as they are partially accurate, there is enough engineering knowledge involving the external world in this part, which is enough for Zheng Yichen to complete it...... Of course, Zheng Yichen, who is not biased towards the otherworldly style, will definitely not make it into an otherworldly style!

"Huh~ Is this a musket?" Dan Marina, who was watching with Petty, watched Zheng Yichen finish drawing the structural diagram thoroughly before asking, "Strange appearance." ”

There is also such a thing as a musket in the Otherworld, after all, there is even a mechanical dragon in engineering, and it is impossible to live without a gun, but the structure still inherits the style of the Otherworld, which is very different from the style of the earth.

"Strange, this is beauty!" Zheng Yichen pouted, the musket of the other world Zheng Yichen has understood, never to mention the internal structure, there are precision and simplicity, but the appearance is very versatile, it looks like a thick steel pipe, and the musket of the other world is not a mainstream weapon, the level of force in this world is too high, and the power of grenades and cannonballs can be exerted with cold weapons and magic, and things like muskets are naturally suppressed.

What is the bow and arrow!?The powerful strong man can shoot the effect of missiles with one arrow, and the musket is useful!?musket, this weapon is suitable for low-end battles in the other world.

snapping his fingers to the side, an alchemy puppet in charge of the assistant's work in the workshop sent the materials that Zheng Yichen needed, for these materials that have been simply processed, Zheng Yichen is familiar with the beginning of the follow-up refining process, even if it is the first production, it is still quite easy for Zheng Yichen, after all, he has tried this kind of production process many times in his dreams...... Zheng Yichen had doubts about this.

Since there is magic that can be used in dreams, why don't you try things in reality in dreams? But after checking some relevant information, he understood, and the main reason is mental power!

When relying on magic to do 'lucid dreaming', based on the interference of magic power, doing many things in the dream will bring additional mental power consumption, the more sophisticated the thing, the greater the consumption, after all, it is not so easy to do lucid dreaming with external forces, as for the real lucid dream, the possibility of appearing in this world is lower than that appearing on the earth!

Zheng Yichen guessed that it was probably because of the special power of magic in this world, and the use of magic would produce magic interference, if not, this interference still exists, but it is only very slight, but it is this slight influence that makes the already low probability of appearance close to zero.

But it's still the same, and the so-called magic interference didn't appear on Zheng Yichen's body...... Of course, even so, the consumption of mental power is still very large, which is also the reason why Zheng Yichen woke up and felt tired after learning the general text in his dream, and the consumption is so big without interference, not to mention those who have interference, it is estimated that doing a sophisticated little experiment can drain his spiritual power!

"Wonderful~" Watching Zheng Yichen produce a firearm in a short period of time, Dan Marina couldn't help but praise, Zheng Yichen's production process is extremely accurate, and there has been no mistake, as if it has been tried thousands of times, capable and orderly, what interests her more is the shape of this 'musket', even if this is a weapon, and there is no connection with building furniture, she can still see that the style of this 'musket' is still the same style in the room where she lives now!

It's just that the branches are different.
