After the twelve elves were taken down by Carlo to arrange accommodation and work, Caesar looked at the empty hall, and finally relieved himself, slumped in a high-backed chair in a position that he had not used for a long time.

A pair of white and tender hands appeared at the right time to help Caesar massage his temples.

Caesar looked down his little hand and saw Adele looking at him with a smile on her face, "Adele, didn't you go out with Anna?"

Adele shook her head slightly, and did not answer Caesar's question, but said, "You have just recovered for a few days, actually...... You can take your time with these things. You raided Ryans's house, and even if you go to play for a few days, it's nothing. ”

It has been almost ten days since Caesar returned to normal, but what has Caesar done in these ten days?

Free the more than 1,000 prisoners in the original mountain dungeon, now renamed the Little Black Room, and use these prisoners to strengthen the defense and construction of Atlanta.

The implementation of two major systems moved everyone in Atlanta, raiding the house of Giggs and taking in three magicians and twelve elven archers.

Even the grassland malignant fish-people repelled it!

Even if Caesar scattered, it would have taken a month or even a year to deal with so many things, but this guy actually took ten days to arrange and implement all of them.

Caesar is back to normal, but Adele is worried that if he continues to work like this, he may become the same Caesar again.

Caesar smiled lightly, gently held Adele's small hand, and said, "Adele, I've wasted too much time, so I can only speed up the completion of these things, and ...... Do you know how much money I have on hand right now?"

"Huh?"

Caesar's question stunned Adele for a moment, but still subconsciously replied: "If I'm not mistaken, there should be almost a million gold coins, and that guy Giggs has collected all of Atlanta's property into his own hands." ”

Caesar nodded: "You're right, Giggs has collected all of Atlanta's property, so all the gold coins in my hand are actually the gold coins of the people of Atlanta!"

"The money is theirs, not mine, and may be in my hands now, but I can't use it for my own reasons, and I've given it all to Philip to deal with, and it's all used in Atlanta's finances. Caesar smiled helplessly: "The most important thing is that we have no foreign trade relations in Atlanta now, so no matter how the money is transferred, it is actually in our own hands, if we want to make this money valuable, we need to restore the trade relationship with the three kings!"

"And what are you going to do?" asked Adele subconsciously.

Caesar stretched out two fingers, "In two months, it will be a gathering of the three kings, so when Rhodes returns to the captain, I will leave for the territory of the Prairie King immediately!"

Since these three kings have been gathered together, Caesar does not have to run three places separately, if calculated according to the distance, Caesar runs these three places, conservatively estimated that it will take nearly a year, and the development of Atlanta will be greatly slowed down in a year, so Caesar can't wait!

It is nearly 30,000 miles from Atlanta to the royal city of the Prairie King, there are not many buildings on the prairie, and you can basically go in a straight line, and Caesar can basically reach it in a month and a half if he is fast.

But it depends on when Rod comes back, Atlanta is obviously targeted, if you don't arrange a big master to guard in Atlanta, then I'm afraid that Caesar will be gone this time, and Atlanta will have been captured by others.

According to the plan, Rhodes should be back in the next few days, so Caesar is also arranging candidates with Philip and Carlo in the past few days to see who to bring with him.

Adele thought for a moment, "Take Anna with you, she's been in Atlanta for a long time, and it's time to go home." ”

"Well, okay!" Caesar nodded, if he was not there, something might happen to Anna and Adele, and he would not have time to come back to rescue him when he was far away, not only to send Anna home, but also to bring Adele over to Anna's territory by the way, although I don't know what the situation is in Anna's territory, but Anna, as the future owner of the territory, is on her territory, there is no problem in protecting Adele!

But that doesn't mean Adele won't be safe in the middle of Atlanta, because Caesar has her sights set on the walls before she leaves!

The walls of Atlanta are loess walls, and the walls are filled with a lot of stones, and then dried with flames, this kind of wall is used everywhere in the prairie, although the defense is there, but the effect is average.

Caesar asked the Great Lord to systematically analyze the structure of the city wall, this kind of city wall is not to mention the stones of catapults, even if Caesar's current physical strength, with just a light punch, the entire wall can be completely shattered.

If the enemy attacked the wall with a hammer, there would be no way for the loess wall to hold up.

So...... Caesar intends to use a material that can be seen everywhere on the earth, and although this material is not available in this world, all the raw materials it needs can be found on Liangshan!

Hmph~ What kind of building is inseparable from the 'cement' thing?

Without cement, how could a building on earth be hundreds of meters high!

The production process of cement is very simple: the limestone is crushed into powder, mixed with clay, calcined by dry or wet method, and then ground with gypsum.

At the back of the castle, next to Allen's laboratory, there is a small tiled house, which at first glance is clearly new.

Alan Magician, the chief laboratory in Atlanta, was sweating profusely in the tiled room controlling the temperature of the flames.

Caesar didn't know the exact temperature he needed to make cement, and even if he did, he couldn't measure and control the temperature – both infrared thermometers and thermocouple thermometers were countless times more complicated to make than cement.

He only knew that the melting point at this temperature was about the same as that of iron, and the calcination process was also a difficulty in the production of cement.

In this era of underdeveloped smelting technology, maintaining blast furnace temperature has always been a problem that bothers everyone.

The heat loss of ordinary open furnaces is large, and it is difficult to keep the furnace temperature above 1200 degrees. And the reverberatory furnace needs a high-temperature resistant liner, and he can't make it.

The traditional iron-making blast furnace is even worse, and the temperature may be up to standard, but if it takes a long time to smelt, it is estimated that it will take ten years to complete the cement of the once-time city wall.

So the firing room designed by Caesar did not have any heating measures at all, and the only heating source was Allen.

Although Allen's strength is not high, he is indeed a genuine third-order magician, and this ability to control fire is a proper problem for him.

At first, Alan didn't believe Caesar's words at all, limestone powder and clay were basically the tricks of those alchemists.

But despite Caesar's insistence, Alan decided to experiment with Caesar and let him know what 'professional' is!

However, there is no such thing as a flag, and basically the flags that are planted randomly are pulled up in the end!

According to Caesar's process, Alan mixed limestone and clay and mixed it with water to form a gray slurry, and then spread it evenly in the firing room, and then baked the slurry on the ground with a flame until the iron rods put into the room were completely melted!

When the flames were completely gone, Alan was shocked that these two things were really as Caesar said, and they actually fused together perfectly!

On the surface, the powder is indeed a mixture of clay, but how can it be used? Can it really be built as Caesar said?

Alan said he would be skeptical!

However, it turns out that the law of true fragrance exists no matter what world you go to.
