While the orcs in the outer towns were turning their attention to the hot air balloon, Alan was instructing the orcs in the blacksmith shop to study the locomotive.

When the military factory was set up, the steam engine in Tomorrow City had developed to the level of a multi-expansion steam engine, and its power could meet the power needs of the locomotive to haul goods.

At that time, locomotives began to be manufactured slowly, and steel tools were cut with lathes to make motion parts related to trains.

Manufacturing a train requires a lot of manpower and time, complex transmissions, steam locomotives, wheels, rails, shelves, etc.

The day before the start of the war, the locomotive responsible for power output had been manufactured, but the shelves and other items had not yet been built, and Alan did not have time to come to the blacksmith shop, which led to the speed of train manufacturing slowing down.

Now that Alan has time to guide, the manufacturing speed of the shelves has also increased, the efficiency of orcs has increased several times, and the scrap rate of forty percent has become zero, making one successful one.

"Lord Allen, has the train tracks to the port been laid?" Abel asked.

"I've already arranged it with the orcs of the Ministry of Construction, and there are thousands of people laying the train tracks today."

Blacksmith Abel was startled when he heard the thousands of people, and hesitated: "Lord Allen, transferring so many people won't affect the construction progress in the city, I know that the second phase of the private housing project is almost finished." ”

"First build the passage from the port to the city, which will eventually lead to the saltpeter town, and hold the saltpeter mine firmly in your hands, the sooner the better." Alan patted the blacksmith on the shoulder, telling him not to stress too much.

Sooner or later, the train tracks had to be built, and Alan just moved the time forward a little earlier.

"By the way, Lord Allen, the large generator is too complicated, can you ...... I mean, set aside an hour a day to teach? Abel said with a sweat on his head.

With the discovery of wolframite in Tomorrow City, Alan had a reason to invent electric light, so the design and structure of the large generator was also sent to Abel's desk.

However, Abel looked at the complicated design drawings, a set of large generators involving stator core, stator winding, rotor, rotor coil, cooling and other devices, each component involved a lot of physical knowledge, dizzying.

It's not enough to have a generator, it needs a terrifying guy to provide power output for a long time.

The power machine that is used with the large generator is the steam turbine, so the design of the steam turbine is also on his desk.

The steam turbine is related to the steam engine, and the two are quite related, but Abel is still a little difficult to understand, which shows that the scientific and technological content is very high this time.

The above two things are the core of thermal power plants, without which generators cannot supply a large amount of electricity with current technology.

Abel also had this feeling of dizziness when he looked at the design of the locomotive before, and later Alan took time to give a lecture to the train manufacturing team to slowly relieve the dizziness.

Last night, he looked at the two sets of blueprints, one of which contained hundreds of drawings, which was very complicated, and he and his team needed Allen's teaching, so he asked this question.

Alan thought for three seconds, "Well, I'll explain it to you tomorrow when I have time, but have you found the manufacturing team for large generators and steam turbines, once you start manufacturing, your team members can't go out of the blacksmith shop to prevent secrets from leaking." ”

Abel hurriedly patted his chest to ensure that no one leaked the secret.

"I'm sure you won't leak the secret, but I'll give you notice in advance, so that they can talk to their families so that they don't get into trouble when they get it."

"Okay, I understand." The blacksmith said respectfully.

After Alan left, Abel smiled bitterly, the mystery of the generator is so complicated, even if someone wants to leak the secret, others must be able to understand it.

Anyway, he felt dizzy when he looked at the blueprints, and there could be no other orc who knew more about machine building than he did.

After Allen came out of the blacksmith shop, he went straight to the school to teach biology, physics, and chemistry, and after he was done, he rushed to the southern mines to teach the bull-headed people a moral lesson.

This back and forth consumes a lot of time, and Alan can't help but think of a bicycle, "I should invent a bicycle to shorten the walking time." ”

With the idea of efficiency, Alan returned to the house after work in the evening, had dinner, and began to draw the design of the bicycle.

But there aren't many workers left in the blacksmith shop, and they all have tasks at hand, and even if they have bicycle blueprints, they don't have the manpower.

"No, the people in the blacksmith shop have a task, I need to free the slaves and increase the population." Alan rubbed his wrist, feeling that there were fewer and fewer people who could use it.

In the final analysis, the population is still small, there is no population, and everything is subject to manpower constraints.

At this moment, Eren longs to conquer all the surrounding villages and towns with cannons and muskets.

……

The next morning.

The sun was hidden in the clouds, and the slight cold of winter did not affect the army, their bodies were still straight, and a hot air of young blood faintly emerged, washing away the slightly cool weather.

The musketeers and artillerymen were concentrated at the gates, and the ranks were like a flat rectangle cut out by a knife, and no one stood out of the ranks.

Allen came to the city gates early and gave an impassioned speech to boost morale, explain the nature of the national slave liberation movement, and let the soldiers not have a psychological burden.

"The existence of slaves is unreasonable, the nobles of the Lionheart Country have been in power for a long time, they have long been unbearable, the people have no room to rise, they are oppressed by the nobles, their spirit has become numb, they don't know how to resist, but we are different, we represent the people, declare war on the cities and towns of the country, and liberate the slaves......"

Alan gave them strong hints, and the soldiers raised their fists and shouted three times in succession, venting their resentment against the tyranny of the nobility.

Among the orcs, Ivan's eyes were red, remembering the fear of her sister being sold to a slave trader.

He knew that there were many slave traders in the world, and they were buying all kinds of slaves in the villages.

Tomorrow City is also accepting slaves, but the nature of Tomorrow City is different, they are transforming slaves, so that slaves can live again, and give them room to rise, rather than a life of eternal peace.

"All the army, go on the march!"

With Allen's order, Ivan led his men out on the expedition and ran into the distance.

This time, the whole army went south by boat, using a total of 2,000 troops and three breech-loading rifled guns.

The first big goal is to go straight to the town of South Bank, take one of the port towns in the south in your hands, master its fishery, provide a large number of live fish for Tomorrow City, and reduce the burden of food.

The second major goal is Shuizhu Port, take it, get rid of all the nobles, and take over all the commerce of Shuizhu Port.

On the way south, they will encounter various small villages that are not indicated on the map, and the army will find a way to relocate them to Tomorrow City.

If you can't persuade it, forget it, Tomorrow City doesn't have to force others to leave their hometowns, they don't look down on the population of two or three hundred people in small villages.
