Han Xinghai didn't understand holographic drawing at all. He could only explore it bit by bit through brainwave reading and search tutorials. The hardships can be imagined.

In fact, with the breadth of Han Xinghai's current knowledge, he has no ability to design a composite bow at all. All he can do is to copy and draw a new picture according to existing technical parameters. This simple cloning is only a few seconds for the residents on the Eternal, but for Han Xinghai, it is extremely brain-burning.

One hour.

Two hours.

Three hours.

Four hours.

...

"Hahahahahaha, I succeeded! Success!"

When Han Xinghai finished the "pulley" holographic drawing and was so happy that he danced and shouted, it was already early in the morning, and Dr. Luo Yi had long disappeared.

Looking at the empty modification room, Han Xinghai, who could not share his joy with others, could only hold it in and copy the drawn pictures into the brainwave reader according to the prompts in the holographic drawing modification equipment.

It is worth mentioning here that in these ten hours of holographic drawings, Han Xinghai himself didn't know that successfully drawing the composite bow pulley was insignificant for him. His biggest gain was that he learned some basic operations of the optical brain, such as data replication, and so on. Before, he could not understand the meaning of replication at all.

Modern people cannot understand the barriers formed by high technology on barbarians. Even if it is just the simplest light-brain operation, it is an insurmountable barrier for barbarians...

...

When Han Xinghai returned to room 00307, ​​Su Ruo exercised in the living room, wearing a gray-white tight clothes, sweating profusely.

"Good night." Han Xinghai did not dare to look at Su Ruo's concave and undulating figure, and walked into the room with a side look.

"Kan Xinghai."

"Ah..." Han Xinghai's body stiffened at the door.

“You’ve dropped a lot of courses.”

"oh."

"By the way, Ran Mengguo has started to contact the mecha." Su Ruo's tone was plain, but his bright eyes were staring at Han Xinghai's eyes. She hoped to see what the barbarian boy thought in his heart.

"oh."

What made Su Ruo vomit blood was that Han Xinghai had no reaction.

"What are you doing with Dr. Luo Yi?" Su Ruo regretted it after asking, because there is a tradition on Eternal Number for more than a hundred years, and they are not allowed to inquire about information from each other. Although this tradition does not have explicit regulations, everyone abides by it carefully.

People from Su Ruo's generation did not know that there was a very dark period on the Eternal - the Falling Period.

As the name suggests, the fall period is a period after the Eternal fell. During this period, the Eternal implemented military control and countless tragedies occurred. This period did not end until Captain Burke took office.

In fact, the influence of the Dark Age has continued until now, and many people have followed the rules set by the Dark Age.

"I have nothing to do, so I read reference books. I am bored and want to make bows and arrows... Hey... Su Ruo, I used my light brain to draw a design drawing of the bow and arrow pulley." Finally, I found the human being who shared the joy, and Han Xinghai's emotions immediately became excited.

"Not bad." Su Ruo was not interested at all, but he still responded politely.

"Look, this is the hologram I drew."

Han Xinghai, who was a little excited, did not notice that Su Ruo was not interested. He quickly put the brain wave reader on his body and the light brain in the living room. A virtual holographic control desktop appeared on his chest. Soon, a hologram of the composite bow pulley he drew appeared on the holographic screen.

Looking at the hologram turning in the air, Su Ruo was lost.

Su Ruo was not lost because of the hologram of the pulley. What made her lose her was that Han Xinghai was able to connect the brain wave reader with the optical and brain devices in the living room. You know, just a few days ago, this barbarian boy knew nothing about holographic movies.

"Su Ruo, how about it?" Han Xinghai looked at Su Ruo with a gaze. At this moment, he was like a child, hoping to win the praise of adults.

"Is this what you designed?" Su Ruo finally carefully watched the drawing of the pulley on the holographic screen, looking surprised.

"Uh-huh."

"Let's take a look." Su Ruo walked to the virtual operating table of Guangwang, and soon, the expression on her face became gloomy.

"Su Ruo, is there any problem?" Han Xinghai felt something was wrong and asked nervously.

"Is this the composite bow pulley you designed?" Su Ruo looked at Han Xinghai coldly.

"Yes..." Under Su Ruo's aggressive gaze, Han Xinghai was a little lacking in confidence, but he still answered with a tough bullet.

Su Ruo's fingers were jumping rapidly on the virtual keyboard, and immediately, another pulley image appeared on the holographic screen.

"Since this is designed by you, who designed this pulley?" Su Ruo looked at Han Xinghai with a sarcastic look.

"I designed it according to the design." Han Xinghai looked confused.

"You are not designing, it's plagiarism! Do you understand what plagiarism means? It's just stealing things and taking other people's things for yourself!" Su Ruo angrily scolded.

"I...I..."

Han Xinghai looked through and stuttered and couldn't speak.

"Trump!" Su Ruo cursed with contempt, turned around and walked into his room.

Plagiarism!

Seeing Su Ruo's door closed heavily, Han Xinghai was muttering, and quickly searched for the meaning of the word "plagiarism" through a brain wave reader.

Plagiarism refers to the act of stealing or modifying other people's works as one's own, and completely copying other forms or contents completely under the same use method, and to a certain extent, a fire is used to change other forms or content. It is an act of serious infringement of other people's copyrights.

After Su Ruo returned to the room, he suddenly felt regretful.

Was the words just now too heavy?

Are you too harsh on the barbarian boy?

Han Xinghai drew a hologram of the pulley of the composite bow completely according to the technical parameters on the Eternal. Although the word "design" is somewhat inappropriate, it is not enough to be plagiarized. After all, the technical parameters of the Eternal bow on the Eternal do not necessarily have intellectual property rights. What's more, the history of the composite bow dates back thousands of years, and even if there is intellectual property rights, it has expired long ago.

Strictly speaking, there is no problem with Han Xinghai's technical parameters of the composite bow on the Eternal. The biggest problem is that the word "design" cannot be used, but it is obvious that a savage boy cannot distinguish the difference between "plagiarism" and "design"...

...

Day 100.

Today is the 100th day that Han Xinghai has landed on the Eternal.

Except for the first few days of free activity, the rest of these 100 days are basically spent on the Eternal.

For Su Ruo, these 100 days are boring, but for Han Xinghai, this is a hundred days that affect their lives.

Unlike a group of barbarian teenagers who have regular daily lives, Han Xinghai's schedule is a bit chaotic because he is Dr. Luo Yi's assistant.

Dr. Luo Yi himself is a person with time chaotic or even reversed. His life is extremely irregular. He often works for several days in a row and then disappears for a few days, which also leads to Han Xinghai often doing nothing.

During these 100 days, Han Xinghai's main job was to make compound bows in addition to doing odd jobs for Dr. Luo Yi.

It is much more difficult to make a composite bow than Han Xinghai imagined. There are dozens of parts for a bow, and it took him more than a month to draw it alone.

In the drawing for more than a month, Han Xinghai’s biggest gain was not that he understood the design principles of the composite bow, but that he learned to use the optical brain.

Now Han Xinghai is very skilled in using light brains. Not only can he search for the encyclopedia through brain wave reading to obtain the data needed as soon as possible, he can also accurately find the data he needs in tens of thousands of volumes of "Chronicles of the Empire".

In the past month, the knowledge system established by Han Xinghai with the help of the queen has gradually become richer, and he has also gained a relatively comprehensive understanding of the development of human civilization.

In the remaining month, Han Xinghai began to use the modification equipment in the exile cabin modification room to produce composite bows.

When it really reached the manufacturing stage, Han Xinghai discovered painfully that the complexity of things once again exceeded his imagination.

The manufacturing process of composite bows is very simple for a modern person, but it is simply a nightmare for a barbarian teenager.

The biggest obstacle Han Xinghai faced at the beginning was the use of modification tools.

If it is just a tool like a file wrench, Han Xinghai is naturally no problem, but the problem is that most of the tools needed by Han Xinghai are high-tech modification equipment, such as CNC machine tools, micro forging machinery and the chemical composition of nano bowstrings, etc., which are technology that he cannot understand.

Moreover, many modified equipment have complex connections with each other, such as micro furnaces and metal analyzers. If the data is not clear between the two, the refined metal products will become as fragile as tofu.

The temperature and time control of forging equipment are also very accurate, and the extended materials knowledge is as vast as smoke.

In this crazy manufacturing, in order to overcome the problem of the composite bow easily breakage, Han Xinghai did not leave the modification room for three days and three nights, and the reason was that there was a problem with a subtle procedure of metal quenching.

rigorous!

During the 100-day process of making bows and arrows, Han Xinghai understood the rigor of science and the importance of material application.

Han Xinghai became more and more serious. When he returned to room 00307, ​​he never took the initiative to say a word.

However, Su Ruo was very happy about Han Xinghai's living habits. She didn't care what Han Xinghai was doing at all. She just hopes Han Xinghai won't disturb her life.

Of course, Su Ruo could not ignore the existence of Han Xinghai, after all, they lived under the same roof.

In fact, Su Ruo also knew that Han Xinghai had been studying the manufacturing of bows and arrows, but she thought it was meaningless. What would it do if it was made? After all, it is the cosmic era, and even airplanes and cannons have been eliminated, and bent bows and arrows have long become a physical activity to exercise.

Early in the morning, Su Ruo got up and used to running in the living room and went back to the room to take a shower. After taking a shower, she remembered that she was running and felt it was too restricted. She took off her underwear and put it in the living room. So she opened the door. When the door just opened a crack, she saw Han Xinghai sitting upright on the sofa watching a holographic movie.

Su Ruo was startled and hurriedly closed the door because she was just wearing underwear.

During this period, because she could never see Han Xinghai, she almost forgot that there was a barbarian boy living next to her.

"Damn savage!"

Thinking of Han Xinghai sitting next to him, Su Ruo had the desire to kill someone at this moment.
Chapter completed!
