When Wren returned from Dow Jones-Perchamps, he got busy, barely rested, and after almost a month, everything was on track, and there were only a few days left before the recapture of Maria's Wall.

During this time, with the opening of the technological blockade, two inventions are worth mentioning, the first is the Thunder Gun.

A spear-like explosive that is so powerful that it can be used with a slightly modified three-dimensional motorized device, in large part because the invention was aimed at the Armored Giant.

Then there is the giant guillotine, which Han Ji created by using the hardening ability of the Attack on Giant, which makes people stand inside the hollow mesh crystal, and the hardened crystals are attached to the outside of the city wall, and when the giant probe wants to catch the people inside, he lowers the spine from the city wall and pierces the back of the giant's neck to kill it.

The guillotine works non-stop, and the Unsullied Giant cannot destroy the hard crystals, and the safety of those who act as bait inside is guaranteed.

Not only these two things, but after taking out the drawings that were previously locked in the warehouse of the Central Military Police, new inventions began to appear.

Although the technology tree in the entire wall has not changed much for a while, it will eventually affect the entire world inside the wall in the long run.

Not only a few inventions, but when the outside world was known, the inner world was officially renamed the Eldian Kingdom, and this name was Wren's suggestion, because with the area and comprehensive strength within the wall, it was too arrogant to call the empire, and by the way, it was also separated from the past Eldian Empire.

The republic, however, is too far ahead of its time, the walls have been closed for too long, the political system is still a bit backward, and the people's simple concept cannot accept the idea of a democratic republic for a while.

Of course, the information about the world outside the wall was not told to the people all at once, nor did it wait until after the recapture war to be fully announced, but according to Wren's proposal, it was released little by little, giving everyone some time to accept.

In addition, proposed by Rennes, a special award was set up, covering physics, chemistry, biology, mathematics, astronomy and geography, medicine, literature, economics and other fields.

The award, which was eventually named the "Hrista Prize", is awarded annually and not only receives a large prize money, but also receives an audience with the Queen and personally presents them with the Order of Distinguished Citizens.

This move has greatly stimulated the enthusiasm of scholars from all walks of life, such as several scientists who have realized the drawings of the thunder gun, nominated for this year's "Hrista Chemistry Prize", of course, it is uncertain whether they can win the award, after all, the first scientists who designed the thunder gun have been killed, and several of them are not inventors.

Not only that, but with the help of many people involved, Wren has also introduced several bills in Parliament.

For example, in the "Three-Year Compulsory Education in the Kingdom of Eldia", the government provides half of the tuition fees and encourages some people who have the conditions to send their children to school, not because they don't want to be free or for a longer time, but because the economic conditions or productivity do not allow it.

The aim is to eradicate illiteracy, and the illiteracy rate within the walls is frighteningly high, with more than 9 out of 10 ordinary people being illiterate.

There is also the "Commercial Regulations", the "Tax Bill", the first to encourage the development of commerce, put forward the concept of "company", which is respected and strongly supported by the Liebs Chamber of Commerce.

The second is to clarify the various taxes and set up a special tax department to put an end to the phenomenon of indiscriminate tax collection and tax evasion, and those local nobles and rural nobles also have to pay taxes.

This caused some waves, but in the end it was carried out, and another monitoring department, Mallo Sander, approached Rennes and said that he wanted to regulate the enforcement of the gendarmerie order.

Nair is naturally very dissatisfied, but with the support of the garrison corps and the survey corps, many people have long been tired of the master of the gendarmerie regiment.

Many of the above bills were put forward by Rennes as an idea, and the relevant professionals were asked to improve them, and then they were revised according to the objective conditions within the wall, and then discussed and adjusted in the parliament, and finally promulgated.

It can be said that the policies and measures not fully enumerated above have greatly aroused the enthusiasm of the people, and the spiritual outlook of the masses in the entire world has taken on a new look.

Wren's actions gave a great shock to the friends of the 104th issue, and similarly, President Daris, Commander Pixis, Nell Dirk, and Head of the Alvin Regiment also looked sideways.

They were also participants in many of the above bills, and even in their opinion, these were genius ideas, and they were not utopian, and Wren came up with these things, especially in combination with the specific situation within the walls, and consulted many people.

"Vigorously developing productive forces" and "rejuvenating the country through science and education" have all been written into the latest edition of the textbook.

Wren is completely famous, the kind that will leave a name in history, this time it is not just a hot lace news, his name is in the textbook.

The Belk newspaper selected the top ten people of the year, Wren ranked third, the first was the queen, and the second was the head of the Alvin who presided over the coup.

At one meeting, President Darris made a joke that Wren was politically wise and fit to be president.

To the north of the Sheena Wall, on a farm in the former territory of Lacey, children are chasing and fighting.

The children were from the Underground Mall, and Heatheria took them to the farm, and there was also the advice of the Commander, after all, Levi was also from the Underground Street of the Royal Capital.

Of course, the queen is not as idle as she used to be, and Sistria usually handles two days of government affairs and comes here to take care of the children for one day.

"Yo, isn't this President Rennes? Why do you have time to come here to play, aren't you revising the charter with someone? Holding a box, Bao said in surprise.

Pouting, Wren said lightly: "I'm done, in the end, I'm just putting forward ideas, and the rest has to be handled by professionals." ”

Wren didn't swell enough to think he was a politician, and besides, during this time, he had basically emptied up all the knowledge he could use.

Picking up a box, Wren walked towards the warehouse, everything was done, there were still a few days, it was the day of the expedition, and then everything would have a result.

Heatheria also saw Wren and waved at everyone, and Wren and Jean walked over.

"Be careful, everyone, it's a pity that I can't go with you." Although she became the queen, in front of her friends, Sistria was still the same.

"Don't worry, we'll be back in triumph." Alan said firmly.

Everyone nodded, everything was ready now, the route had been discovered by the vanguard, and they would set off in a few days.

Wren and Heatheria chatted for a few words, and they didn't have any children's affections, and they weren't like each other, they were just more familiar, and now at this time, it was a bit extravagant to talk about feelings.

Time passed like an arrow, and on the last night before departure, the military prepared a celebration banquet in advance to celebrate the triumph of the survey corps.

The big cafeteria was brightly lit, and 374 members of the Survey Corps were eating, and the atmosphere was quite lively, of course, everyone was not much optimistic.

Now all the people present are veterans, Reiner didn't snatch Allen away, and the regiment commander naturally didn't take anyone to chase him out, so he didn't lose many elites.

Without losing an arm and losing too much blood and being in a coma for several days, Alwin's preparation time was much longer, and when he was wanted, Oluoban assisted the commander, and Han Jiban's men took people into hiding, and kept a lot of manpower.

The soldiers of the 104th phase have also grown, a total of 374 people, the number is sufficient, as for the new soldiers who joined Mallow and Flock, who have little experience, naturally they do not have to participate in this battle.

Oluo put a piece of meat in his mouth: "Eat more now, it's not good, this is our last meal." ”

Petra smiled: "We are still alive, and we are lucky, when I took people to hide, I was almost discovered by the patrolling gendarmes." ”

Without saying a word, Oluo buried his head in dinner, and when he fought with the Central Military Police, all the members of his squad hung up, and he did not form a combat squad at present.

The other table next to it was much more lively, and Wren hugged Sasha and hurriedly shouted: "Sasha, don't be impulsive, if you eat all the meat, everyone will kill you." ”

Connie stopped in front of Sasha with a vigilant face, swallowed his saliva, and glanced behind the table: "Let, cut it quickly, don't think about eating it if you don't divide it again." ”

"I'm busy, just a while!"

Let Bao Zheng take a knife and fork and cut the fragrant piece of beef with Ah Ming, and the two of them acted quickly.

Alan shook his head, what is this called, it may have been hunting with Wren, more than three months ago, Sasha went to the chief's food bank to steal meat.

There was a burst of chickens and dogs, and the recruits of the 104th issue divided the meat, and the veterans watched this scene, and no one said anything cold.

The next day, when Ymir arrived in the uniform of the previous Survey Corps, everything was ready.
