The moon hangs in the night sky in a light veil, the stars are dotted, the wind on the summer night is quite cool, I have to say, the air quality here is very good!

On the evening of the fourth day at the castle, the uniforms made for the recruits were delivered, and Wren put on the uniform of the Survey Corps with the Wings of Liberty pattern, and put on a green cloak, and the whole person was in good spirits.

He was about to go to the castle with Amin and Connie to admire the moon, but was called away by Moblit, the deputy leader of the fourth detachment.

"Senior, is there anything Captain Han Ji looking for me?" Wren was a little confused, he shouldn't have dealt with Han Ji at the moment.

Mobritt was also very strange, not understanding what his squad leader was thinking: "I don't know, the squad leader is busy making flares in the laboratory now, and it will be clear then." ”

Wren nodded and didn't think much about it, and rushed to Han Ji's laboratory with Moblit, and Han Ji took a lot of effort to transport all kinds of equipment in the past two days.

The door didn't close, and Mo and Wren entered the lab.

As soon as Wren entered, the first thing that caught his eye was rows of test tubes, containing various chemical reagent bottles and cans, followed by distillation bottles, rulers, tweezers, rubber tip droppers, gas tubes, etc.

On the experimental table, there were several disassembled flares, and various pigments were slightly sprinkled on the table.

What caught his attention the most was an optical microscope, the style was a bit old, like the Hook microscope in the biology textbook when the earth was on, Wren squinted his eyes slightly, he had been here for three years, and it was the first time he had seen so much experimental equipment.

Inside the walls is not the Middle Ages, there are also various disciplines here, physics, biology, chemistry, medicine, literature, etc., the development of physics and biology, chemistry, medicine, literature, etc., is roughly at the level of the 19th century on the earth, of course, a lot of knowledge has been castrated, especially astronomy and geography, literature is also limited, and those knowledge and books about the world outside the walls have been processed!

According to Wren's understanding in recent years, there are also various schools within the wall, and there are several universities within the wall of Sheena, of course, compared to nine years of compulsory education, ordinary people here cannot afford to go to school.

And the captain of the Han Ji team, who was rummaging through the cabinets at this time, took out a glass jar containing a silver-white metal block from a shady corner, and Wren stared carefully at the thing in her hand, making sure that it was most likely magnesium.

He used to be a good student, and although he didn't divide the arts and sciences in junior high school, he still had a good score in physics and chemistry.

"Hey! Wren, good evening, find a stool to sit on, you're welcome. "Han Ji doesn't have any arrogance, it's very casual.

Wren sat on a stool and looked at Han Ji, who was busy disassembling a signal flare, a little strange: "Captain Han Ji, is there anything to do with me?" ”

Mobritt on the side was also a little curious, Han Ji's hand kept moving, and said with a smile: "It's nothing, I heard that you said it on the night of the graduation ceremony."

Our knives are not sharp enough, our cannons are too powerful, and the accuracy is not enough. But as long as the weapons are upgraded from generation to generation, one day, we will be able to blast the giant's head and the back of the neck into slag with a single shot! ”

Wren was a little stunned on his face, this is that he has already been investigated? It's scary, she shouldn't have checked her background.

His expression became a little serious: "Yes, I said that, and I thought so at the time. Now I'm even more convinced that I was right! We can't put all our hopes on Allen, and the power of giants is unreliable after all! ”

Wren really feels that he can't rely on Alan to be the savior, it's unreliable, and now Alan is too impulsive, and hatred burns his reason, just like him back then.

When Karen was at his craziest, he didn't blink an eyelid when he tortured orcs, and after seeing his friend who had died tragically in "Hell", he was full of thoughts about how to kill the entire orc race!

He really knows Alan now, and in his opinion, Alan is actually very twisted in his bones, he is really going to be pushed to the extreme, he really does anything crazy!

"Oh, how do you think we should defeat the giants, weapon upgrades take time, don't you think Alan's power of giants can help us reclaim the Wall of Mary?" Han Ji turned his head and stared at Ren curiously, she thought his idea was very interesting, so she specially talked to him today.

"I also think that Allen's strength is very critical at this time, but after all, it is not a long-term plan, encouraging invention and creation, and making every effort to develop science and technology is the real hope of mankind!" Wren said categorically.

His mind is not bound by this world, in Wren's opinion, the power of giants is not so invincible, the world nuclear level understands?

There is no Newton in this world, but there is nothing wrong with the development of science, and after several years of thinking and observation, Wren determined that except for the power of giants, everything else is very scientific.

Now the howitzer inside the wall can blow up the giant! It's just that the accuracy is not enough, and the filling speed is a bit slow. So, going all out to climb the tech tree is the way to go!

Han Ji stopped what he was doing, walked up to Wren, lifted the frame of his glasses, and stared at him: "But you know what? Except for a few technologies, such as three-dimensional mobile devices, Wang Zheng has been suppressing technological innovations, and even the upgrading of artillery is slow. ”

His eyes were a little cold, and Wren's expression was indifferent: "Of course I know, so we must let Wang Zheng change his policy and make every effort to develop science and technology." Otherwise, there is no hope for this world......"

Wren told Hanji and Mobritt the opinion of the female garrison with short silver hair, including that there might not be a suitable boulder to block the gate of the Higanshina district and that the supergiant might kick open the gates of the Torloster district or other urn cities again!

Han Ji was a little silent after hearing this, Mobritt was not in a good mood, and the current situation was that humanity was struggling to survive.

Han Ji sighed: "We are indeed too passive, even if we want Wang Zheng to let go of technical suppression, it is difficult, for a hundred years, Wang Zheng has never changed his policy in this regard!" ”

His eyes were slightly cold, this incident had actually made Wren feel like a fish in his throat, as uncomfortable as eating a fly, and his voice was a little erratic: "Yes, what's the use of us wanting such a king!" ”

His face was shocked, and Mobricht's body shook, these words were no longer as simple as a big rebellion, and Han Ji couldn't hide his surprise: "Wren, do you know what you're talking about?" Your thoughts are dangerous! ”

It's been three years since he came, and Wren also knows how deeply rooted the rule of the royal family within the wall is, but this can't restrain him as an outlier, Wren didn't change his face, and said coldly: "It's not me who is in danger, but the thoughts of the kings and the policies of the kings!" Captain Han Ji, we can't defeat the giants today, and we even have to fill it with human lives, all because of the fault of technical suppression!

If we had made every effort to develop various technologies in the past hundred years, this would not be the situation today, not to mention anything else, the howitzer alone could make the giants eat a pot, and the technology for the giants such as three-dimensional mobile devices may not be able to have a few more!

So it's not me who is in danger, it's Wang Zheng! I don't know if they did it on purpose, but what they're doing is pulling millions of people inside the walls to bury them! ”

Mobritt looked at Wren in shock, unable to believe what a recruit had said.

Han Ji's eyes lit up, and he was excited: "Haha, haha!" What a funny idea you have! So what do you think we should do? Technology? ”

Wren bowed his head slightly and pondered for a while, he had a habit of reading, he had carefully read the junior high school history textbook back then, and he knew very well how an incomparably glorious country could be trampled on by anyone!

Now that the human beings inside the wall are trapped in a small wall, and then suppress the development of science and technology, isn't it another kind of "closed country"?

The Qing Dynasty is dead, is there any future for this set?

Thinking of this, Wren suddenly stood up from the stool, opened his arms, and said very firmly: "That's right, our only way forward is science and technology!" ”

Xiao Mo didn't know why, and suddenly felt that Ren and the Divine Stick of the Wall Sect were a bit similar at this moment, but their beliefs were not the same.

Mr. Lei: I crossed, I cultivated fighting spirit, I came back from the dead, but I still believe in science!

Han Ji looked at Wren as if he was looking at some precious animal, and asked curiously, "Wren, do you have any good ideas about dealing with giants?" ”

She has invented a lot of tools in order to capture the giant alive, and this plan to capture the giant of wisdom alive includes her invention, and she is one of the few people who now knows Alwin's full plan.

Wren sighed, hating himself for being uneducated, but he still gave a brief introduction to inventions such as hot air balloons, grenades, and machine guns, whether useful or not.

The more Mobrit listened, the more surprised she became, and the more Han Ji listened, the more excited she became, she suddenly slapped her hands on Wren's shoulders and shouted excitedly: "Wren, you are such a genius!" From today onwards, you are a member of Han Jiban. ”

Wren: (๑ ̇ー ̇๑)

Mixed three worlds, the first time someone praised him as a genius, looking at Han Ji with a fanatical face, the trace of pride that Ren had just risen was gone, and the person in front of him was not a normal person, just listen to this compliment, don't take it seriously.

Wren inexplicably joined the "promising" Han Jiban.

At present, there are six people in Han Ji's class, Han Ji himself, Mobritt, Nifa, a girl with short red hair, Cage with black hair and a flat head and thin cheeks, and Goris with short blond hair and glasses. Finally, there is the "genius" Wren who was appreciated by Han Ji.

In fact, Wren now has a lot of meritorious deeds, and the military merits accumulated during the war are recognized no matter which corps he goes to, according to Han Ji, after this extramural investigation, let him officially join Han Jiban.

Xiao Mo felt that there was no problem, today he opened his eyes, Wren left a deep impression on him, although he is a new soldier, he must have strength and strength, he must have brains, and he is bold, and his military achievements are not small.

That's it, Han Jiban, Mick class, and Levi class are all 6 people now, and they are all full!

Mikban includes: Mick, Nanabha, Gruga, Haininga, Linai, and Toma.

The Levi class includes: Levi, Oluo, Petra, Held, Gunda, Allen.

And the squad directly under the detachment leader is actually quite special, such as Nanabas, in addition to being a member of Mick's class, she is also the squad leader.

Today's incident had a big impact, and after a certain wolf exterminator and dangerous element learned about it, he decided to find a time to talk about a plan with Rennes, a "comrade".
