Commandant's Office, Office.

Commander Pixis sat on the desk, on the leather sofa next to the wall, there were three people, Ian and Heatheria were sitting together, and Erwin, with a blue nose and swollen face, was looking at Pixis.

Hanji put an AK-47 on his desk and stood aside.

"Thank you." Pixis's bald head reflected the candle flame, and his beautiful lieutenant, stood behind him.

"Is this a new musket?" Pixis picked up the AK-47 and observed: "It's really a structure I've never seen before." ”

"The name is AK-47, and it's a musket that fires 30 rounds at a time." Hanji pointed to AK's magazine and said, "The bullet is in this shank-type structure, and if the bullet is fired, there is a spare magazine nearby, so you can change it immediately." ”

"It's... It's a little scary..."Pixis's 10,000-year-old squint and smile finally fluctuated: "Although it came from Erwin's mouth, but before I saw it, to be honest, I don't believe it, but you have also proved your strength, anyway, you have relied on this weapon to cross the wall of Sheena and rescue Erwin and the prisoners of the Survey Corps." ”

"No... This is also thanks to the commander who transferred the garrison corps, otherwise we would not have been able to enter the royal capital so easily. Hanji said.

"That's the end of the pleasantries." Pixis took a sip of the black tea on the table: "I took into account all mankind to reach this condition with Erwin. ”

"In any case, the government's decision to send all the unemployed people in the wall of Maria into the mouths of giants is a bit too much."

"This stage of cooperation has come to an end, and the plan you said can solve the food problem should be explained to me in detail."

"Let me tell you." Ian jumped off the couch.

"Erwin, is this kid your relative? I haven't heard of it, you have a child, it's so late, shouldn't you send the child to bed? Pixis squinted at Ian.

"Commander Pixis, although I am only eleven years old this year, the AK-47 on your desk, its first design in the world, was drawn by me." Ian said without changing his face.

"Kid, are you kidding?" Pixis touched his chin.

"No... Commander, this is indeed true. Hanji added, "Actually, the watermill that is quite popular in the Pioneer Land was also designed and built by Ian, so please don't treat him like a child." ”

"Are you serious, Hanji?"

"On such a serious occasion, would we fool the commander with false information?"

The smile on Pixis's face suddenly disappeared, and he clasped his hands together and looked at Ian coldly.

Ian stared at him expressionlessly, his eyes showing no sadness or joy.

"Let's start with where I came from, Commander, so you might trust me a little more."

"I'm from the Lacey Territory of the Wall of Rossay, working on a private farm of Lord Lacey..."

Ian begins to introduce himself, repeating the story of the Lord of the Wall, the Giant, and explaining who Heatriath is and how he investigated the Legion.

"That's about it." Ian said: "But I think the commander should be more concerned about the problem of food, it is about to be the autumn harvest season, if the autumn harvest is not enough, there will definitely be civil strife, the government has made a decision, to send part of the population to the wall of Mary to be consumed." ”

"The commander took such a big risk to assist us for the sake of mankind, and we didn't want to see such a tragedy, so we decided to overthrow the royal government and implement a new policy."

Ian looked at Hanji, who took the suitcase on the couch with understanding, and when he opened it, there were stacks of drawings inside.

"This is the blueprint of the steelmaking plant and the new ironmaking method, which is full of new steel formulas, reducing the cost and manpower consumption of ironmaking to two percent of the original, and the steel smelted can be comparable to 100 steelmaking." Ian introduced them one by one.

These drawings have old drawings as well as new ones.

In addition to the drawings of the steel mill and the iron plow, there are also recipes for fertilizers and flowcharts for making them.

Not only that, but it also includes the technology of glass greenhouses.

"With a steel mill, we can make large quantities of steel ploughs, which will allow more fields to be cultivated, fertilisers to provide nutrients for crops, and crops that can thrive on slightly more barren land."

"The most important thing is the technology of this greenhouse." Ian pointed to the blueprint of the glass greenhouse.

In fact, the best is the plastic greenhouse, but with the industrial level of Pa Island, there is still a long way to go to make plastic, although modern plastic is very cheap, but the molecular technology involved in the back is not a moment and a half to develop.

After Ian consulted Asuka, he obtained the blueprints for the glass greenhouse and the glass factory.

Recently, the time in the dream has been slightly longer, about 20 minutes, and the interval between dreams has become shorter and shorter, from 28 days to 26 days.

In this way, in another seven or eight years, it may be possible to synchronize the time with Asuka in the future, and I will be able to learn from my dreams every day.

But that's all for later, Ian continued to introduce the glass greenhouse, so loud that Erwin could hear it clearly.

"This glass greenhouse can retain the heat of the sun's rays in it, and it can achieve the same effect as a greenhouse without burning a fire, so that crops can be grown in winter." "There are still three months to go before winter, and as long as we can take power and pool the power of the people, we can quickly create a batch of glass greenhouses to grow sweet potatoes, potatoes and other high-yield grains to relieve the pressure on food," Ian said. ”

"By surviving this winter, we can spread waterwheels, fertilizer, and metal rakes to all towns next year, so that even if we lose the Wall of Mary, we can feed all the human race, and even have a surplus."

As Ian spoke, both Pixis and Erwin stood up, and everyone gathered around Ian, including Pixis' female lieutenant.

Ian told them how the glass greenhouse kept the temperature, the principle was very easy to understand, and the three of them were amazed by this technology, although it was a very simple technology, but the mystery contained in it made people applaud.

Just then, Petra appeared at the door.

She lowered her head and reported loudly: "Report to the commander, report to the regiment commander!" Commander Levi has led the Survey Corps and the Commander's direct corps to break through the Wang's government, and the road to the government hall has been opened! ”

Ian looked out the window, the capital was still silent, but something was coming.

It was the tide of the times, and everyone in the room could feel it, and the invisible but turbulent wave was about to sweep over everyone.
