Cement is so magical that the anti-lion Anderson family lions are intrigued.

The construction of a city in two months is no longer a myth, as long as there are enough slaves and a whole circle of orcs start work at the same time, it is enough to build an invincible city wall that is unattainable.

Saltpeter Town is not the base camp of the anti-lion faction, but it is one of the important towns of the anti-lion faction, and its mayor is a person from the Lionheart country on the surface, but secretly he is an anti-lion person.

Saltpeter Town also has a city wall, which is built to resist the tide of medium-sized beasts, and the wall is not very high, only about six meters.

This height could not stop the Templars at their prime, and they could climb the wall and cut down the anti-lion faction by climbing a ladder and jumping vigorously.

The wall is too low, can you build a high point?

Tax evasion and the like can be deceived in various ways, but it is visible to the naked eye to carry out large works on the city wall.

As long as someone comes to the royal city to discuss a few words, it will always reach the ears of the royal orcs, and then the matter can be big or small, and it is not good for the long-hidden anti-lion faction.

"If this thing is true, we only need to gather tens of thousands of slaves to build a Great Wall front separating the north and south, and the south is our territory, with a vast territory that is enough to produce and sell ourselves.

Soldiers patrolled the edge of the Great Wall, lit beacons when there was an enemy, and the nearby military camps quickly provided support, and the Lionheart's offensive could only be interrupted by us.

I call this great project the Great Wall of a Thousand Miles, a thousand miles is enough to separate the north and the south, and we will all be the heroes of the new king. ”

Goss stared at the wall, his eyes full of greed.

"However, a bag of cement costs a gold coin, and as far as I know, the price of building a wall around the town is still within the reach of our family. But the golden dragon needed to build a Great Wall separating the north and south is terrifying, far from what we can afford. ”

Fox coughed, reminding everyone that the price of cement was not copper coins, nor was it in silver dragon units, but the starting price of gold dragon units.

The patriarch and clan elder were stunned, "Yes, cement was not invented by us, this thing is something from Tomorrow Town." ”

What a thousand miles of the Great Wall, separating the north and the south, without money is a pipe dream, impossible to achieve.

"Since it's expensive, then try to find a way to set out the cement formula and production method of Tomorrow Town, or forcibly rob people, use beauty tricks, tie up with flowers, torture and wait, there is always a way to get a way." The sixty-seven-year-old clan elder patted his stiff old waist, and his face was as usual, as if he was saying something insignificant.

Goss and his father and uncle glanced at each other, and their eyes were calm, and they seemed to acquiesce.

"But they have a lot of Awakened."

Fawkes is not against forced robbery, but Tomorrowtown is not a soft persimmon, it is hard rock to gnaw.

"How many?"

"At least four hundred." Fox's computing power was not that strong, and he could only roughly estimate from the dense crowd he saw at the school practice that day.

"So much!" The patriarch was surprised, beyond his expectations.

"Why are there so many, isn't the predecessor of Tomorrow Town the Great Iron Village of mining, his foreign population is almost all slaves, a small part is free people, those people are definitely ordinary orcs, it can't be the awakened." Goss's father couldn't help but raise his slightly round question mark tail, feeling very incomprehensible.

Goss was also shocked when he first went to Tomorrowtown, but now he was not so excited, and thought, "Don't forget, this is a town with a big wall built in two months, and I think they have additional resources, such as support from other countries. ”

"Is it the Bull Head Country?" Fawkes speculated.

"The opportunity for the rise of Tomorrow Town is too coincidental, just in time to make a big move when the Bullhead Country is coming, it is possible that they are spies sent by the Bullhead Country."

"But when I walked around their town, I didn't see any minotaurs."

"Some of the houses are walled and you can't go in, maybe the minotaurs are hiding inside?"

The more the lions thought about it, the more they felt that it was possible, after all, the only country bordering the eastern part of the kingdom was the Minotaur Country, and the country that started the war was also the Minotaur Country, and as long as the orcs with a slightly normal IQ would associate the abnormality of Tomorrow Town with the Minotaur Country.

……

While the anti-lion forces in Saltpeter have a plan for Tomorrowtown, Alan returns to the glassworks to inspect the round glass bottle they blew yesterday.

In the open space of the glass factory, there are more than 100 glass bottles, which are pure and transparent, and they sparkle in the sun.

I dare not say that it is 100% transparent, but the quality of this transparency is close to that of later generations of chemical test tube supplies.

The orcs looked proudly at their glasswork, expecting Alan's compliment.

"Everyone has worked hard and done a good job."

Alan commented lightly, not extremely exaggerated, but the slaves and orcs who had worked hard all day were very moved, and they were for this sentence.

"We don't work hard!"

The orc blushed, fearing that his voice would be quieter, and he shouted very loudly.

"Don't work hard, do it seriously, today we want to make optical glass, listen carefully!"

The orcs don't know what optical glass is, but what Eren teaches is certainly not ordinary, and it should be a glass-making technology that is ahead of its time.

"To make optical glass, there are also three steps of smelting, forming and annealing, and there are single crucible intermittent smelting during smelting, continuous smelting method in pool kiln, and forming method ...... breaking pot, rolling method, pouring method, etc."

As Alan spoke, he began to practice, turning on both the full-level teaching ability and hypnotism at the same time, and the stupid orcs listened to this optical glass making class, even if their memory was not good, they would be deeply impressed in their minds.

At that time, as long as the master in charge of making glass commands the scene, the slaves can still complete the glass making according to the steps in their impressions.

Buck was hungry for these advanced glass-making experiences, and there were many things he didn't understand, such as the stress in the glass, the optical uniformity of the glass, and other strange words.

When it comes to these places, Allen doesn't explain them in a big way, because it's one thing to understand thoroughly, and it's another thing to memorize them on the spot.

Before Lionman Buck did not have the corresponding knowledge of chemistry and physics, full-level teaching and hypnosis did not cure the symptoms, and there was no need to delve into the principles of each step.

The fire burns, and the lever becomes an exquisite performance prop in Allen's hands, turning the molten glass into a large blank step by step.

After careful manipulation, Allen made several optical glass mirrors, which were thick in the center and smooth and transparent in the surface, and their optical refractive index was determined by identification, and the two can be superimposed to magnify objects at very high magnifications.

The slaves who followed Eren were taught to be rigorous in their production at the full level, and most of them succeeded.

Looking at the uneven glass lens in front of him, Buck was confused, but when he picked up the glass lens and looked into the distance, he suddenly made something unusual.

Everything seen through this lens is distorted and magnified.

"It's ......" Buck's eyes widened, remembering that when he used to make glass, he had the experience of enlarging the inside of the glass, and mistook it for a scrap product.
