"I said, this is my workshop. Can you not come in without permission?" Zheng Yichen looked at the woman next to him who was watching the party. The latter seemed to have not heard Zheng Yichen's words, but just summoned a projection of a summoning book of the magic weapon in front of him.

"..." Looking at this thing, Zheng Yichen's eyes hopped slightly. The witch was also interested in the summoning book of demon soldiers? Even though Zheng Yichen can now create a high-level demon soldiers, that thing is still nothing in the eyes of the witch, right?

"I just want to know when can I add some magic weapons suitable for witches?"

"It's suitable for the witch...ha." Zheng Yichen pulled a face and smiled inexplicably, "What a joke, the witch's abilities are so strange. How could I have the ability...Damn!"

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

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

"Even if you are curious, you should be satisfied after so long, right?" Zheng Yichen asked back. Because of this girl, there was no substantial progress in Zheng Yichen's desire to strengthen his strength during this period.

"Don't you know that some things are covered up and the more you want people to know?"

Zheng Yichen smiled untidy. Although he was still a little tenderer than the old monsters, it was much better now than himself who had traveled to another world at the beginning. He dared not fully guarantee other aspects, but his identity would not be directly exposed. Seeing that Dan Marina was determined not to leave her workshop voluntarily, Zheng Yichen gave up the idea of ​​expelling her.

He took out the plan that had been backlogged for a week. After so long, he was about to start working. There is no shortage of materials for the time being. After all, he cooperated with Qin and a witch with an unexposed identity is still extremely large. Although Zheng Yichen has a high demand for materials, he is still alone after all, and he is still incomparable to the resources required by those forces.

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

Research is not divided into race, even goblins... If you really do important research, the resources consumed are not much different than the resources consumed by the dragon. However, because Zheng Yichen has the knowledge of the earth, he works on the shoulders of giants. Although he uses resources very much during research, he avoids most of your wasteful steps and uses resources at a higher level!

Ignoring Dan Marina beside him, Zheng Yichen spread a piece of white paper on the workbench, picked up a pen and thought for a while, and began to draw a new structural diagram. When on earth, because the Internet was developing too explosively, many things can be found on the Internet.

In addition, before traveling through time, Zheng Yichen was very idle on the earth... When he was fine, he would search for something on the Internet. Over time, he accumulated a lot of "miscellaneous learning" knowledge. In the past, he was not strong enough, so he basically forgot most of these things after reading them. Now that his power has increased, his memory has increased rapidly. All the knowledge that has been seen but hidden in the depths of memory can be searched...

There are many structural diagrams of firearms, which may not be absolutely accurate, but as long as the part is ensured to be accurate, this part involves engineering knowledge and is enough for Zheng Yichen to complete it... Of course, Zheng Yichen, who can not be biased towards the style of the other world, will definitely not make it into a shape with a style of the other world!

"Hey~ Is this a musket?" Dan Marina, who was watching with Petty, asked after watching Zheng Yichen completely draw the structural diagram, "Strange appearance."

There are also muskets in other worlds. After all, there are even mechanical dragons in engineering, so it is impossible to have no guns. However, the structure still inherits the style of the other world, which is very different from the style of the earth.

"Strange? This is beauty!" Zheng Yichen curled his lips. Zheng Yichen had learned about the muskets from another world. They never talked about the internal structure. They were precise and simple, but they were very general in appearance. They looked like a thick steel pipe. Moreover, muskets from another world were not mainstream weapons. The level of force in this world is too high. Using cold weapons and magic, you can exert the power of grenade shells. Muskets were naturally suppressed.

What? Bows and arrows!? A powerful man can shoot the missile with one arrow, and it must be of use to muskets!? Muskets, this weapon is suitable for low-end combat in other worlds.

He snapped his fingers to the side, and an alchemy puppet in charge of assistant work in the workshop sent the materials needed by Zheng Yichen. Zheng Yichen was familiar with these simple processing materials and began to refine them later. Even if it was the first time, it was still quite easy for Zheng Yichen. After all, he had tried this production process many times in his dream... Zheng Yichen had some doubts about this.

Since there is magic that can enter dreams, why not try things in reality? However, after checking some relevant information, he learned something. The main reason is spiritual strength!

When relying on magic to do the "Qingming Dream" based on the interference of magic, doing many things in the dream will bring extra mental consumption. The more precise the matter, the greater the consumption. After all, it is not that easy to make a Qingming Dream with external forces. As for the real Qingming Dream, the possibility of appearing in this world is lower than that on earth!

Zheng Yichen guessed that it was probably because this world had a special power such as magic, using magic will cause magic interference. If not, this interference still exists, but it is just a slight impact, but it is this slight impact that has already low probability of occurrence to be close to zero.

But it is still the same. The so-called magic interference did not appear on Zheng Yichen... Of course, even so, the consumption of mental power is still very large. This is why Zheng Yichen woke up and felt tired after learning general texts in his dream. The consumption is so large without interference, let alone those who have interference. I guess a precise experiment can drain your spiritual power!

"Excellent~" Looking at a gun produced by Zheng Yichen in a short time, Dan Marina couldn't help but praise that Zheng Yichen's production process was extremely accurate, and there was no mistake before. It was as if it had been tried thousands of times, so it was sophisticated and orderly that she was even more interested in the appearance of this "musket". Even though it was a weapon and had no connection with architectural furniture, she could still see that the style of this "musket" was still the same as the style of the room she lives in now!
