"Lord Allen, what's so happy?"

"It's nothing, Ivan found two more of his kind." Alan waved his hand, returned to the blackboard, and picked up chalk to explain the structural diagram of the steam turbine.

"Kindred, could it be a pure human race?"

The blacksmiths below showed curious expressions, Alan is so good, what about his people, will they be just as good?

"Be quiet, listen to the class."

Alan taps on the blackboard, and the sound of chalk clicks and clicks, with an invisible magic that instantly turns a restless classroom into a class of full attention.

The orcs looked at the steam turbine pattern drawn by Allen, which was a structural diagram of a reactionary steam turbine, with dozens of wheel blades, each blade closely arranged, neat and standardized, full of the beauty of industrial design.

Steam turbine, one of the core equipment of thermal power plants.

Abel the blacksmith took a pen and muttered:

"The expansion of the steam in the nozzle and blade channels accelerates, and the direction of the steam flow changes as it passes through the moving blades, the relative velocity increases, and the blades are therefore affected by reaction forces......

This is just the beginning, each structure of the steam turbine has a lot of scientific knowledge, Allen's invention of the steam turbine adopts axial flow, and the energy changes generated by the moving blade grid of each stage are very complex.

If you don't look at those mathematical formulas, Abel feels that he doesn't fully understand the internal changes of the steam turbine, so he sank into his heart, and his mind completely followed Allen's voice, step by step into the inside of the steam turbine, watching the blades turn, watching the hot steam expand and accelerate in the steam turbine, level after level.

"As you can see, when the steam enters the turbine blade grid, the blades will be affected by impulse force, but when the steam leaves the vane grid, the blades will be subjected to reaction forces......

Alan spoke step by step, and the two skills of full-level teaching ability and hypnotism were full.

The craftsman who listened to the lecture seemed to be in a thermal power plant, watching the big steam turbine in front of him spin wildly, and vaguely understood many principles, "It's incredible, the working principle of the steam turbine uses both the principle of impulse and the principle of reaction to do work......"

The craftsmen's eyes were empty, unfocused, no one knew where he was looking, or rather, their minds sank into their minds, listening to Alan's image and digesting their newfound knowledge.

……

In the evening, Ivan received a reply from Alan.

When the orc soldiers saw the letter, they all came over to wonder if Allen's decision was in line with the hearts of the soldiers.

Ivan didn't dare to show them, in case Allen's decision didn't go to everyone's will, and it was possible to chill the enthusiasm of the soldiers, he decided to look secretly.

"Wait a minute, let me see first." Ivan pinched the letter and let the crowd disperse.

The orc soldiers looked at Chief Ivan with resentful eyes, but they couldn't resist.

Ivan walked up the tree in two steps, opened the curled letter on the tree, and slowly opened the corner of the letter.

"I will send someone to investigate this matter thoroughly, not to let go of a bad person, not to wronged a good person......"

Seeing these lines, Ivan knew that the matter was done, and Alan would punish the orcs with unhealthy personalities as slaves and send them to the reform camp to reinvent their lives.

At the end of the letter, Alan emphasized one more thing.

"If you encounter pure Terrans, no matter what means you use, find a way to escort them to Tomorrow City, they are all excellent teachers in the future, and they will be of great significance to the education industry of Tomorrow City."

Ivan had no other thoughts, of course, and directly believed Allen's words.

Looking at the entire letter, without any ill words, Ivan stood up and faced all the soldiers, his gaze sweeping over their expectant faces one by one.

Seeing the smile on Ivan's face, the soldiers felt a sense of anticipation even more, and guessed that what was going to be announced next was good news.

Ivan took a deep breath and read out the words that Eren had written, line by line.

The former slave musketeers stood under the trees, taking a deep breath, their eyes warming up.

Listening to those sonorous and powerful words, the orcs all felt the righteousness in the heart of the Allen City Lord, and their chests unconsciously had a kind of qi, filling their whole bodies and being warm.

When listening to Ivan's letter, some of the lion orcs directly awakened and had the function of a lion's roar.

In addition to the cat clan, there are also some werewolf clans, pig people and other orcs who have also awakened.

Ivan, as an awakened cat clan, had a very keen perception, and found that there were hundreds of powerful breaths in the venue, and even he himself was stunned for a moment.

Why did they suddenly wake up, you must know that they didn't do heavy physical work tonight, but they just listened to him read Alan's letter.

There is a magical charm to Allen's letter that makes one feel confident and proud.

Ivan touched his chin, wondering if it could be the cause of the change in mood.

After reading the letter, Ivan passed it down to more orcs.

Many orcs rushed to snatch the letters, muttering over and over again, and those who did not weep also silently left tears, which were tears of emotion.

Even a resolute person may melt away.

Ivan silently recorded the changes in the crowd at the margins and wrote down his own analysis.

"Their changes may be related to emotions, and it has been analyzed in the previous arousal analysis, and the training method is related to emotions......

By about ten o'clock in the evening, Ivan had obtained a large number of samples for analysis.

Perhaps when a person's emotions reach a critical point and break through the critical point, it is possible to awaken their own talents.

Of course, awakening doesn't have to rely on emotions, for example, the way the rabbit-eared people eat herbs to awaken potions is different from the way most orcs awaken.

The dove set out in the middle of the night, arrived in the city of tomorrow early in the morning, and delivered the letter to Ivan in the morning.

Ivan had now arrived on the outskirts of Southbank Town, counted the number of villages he had passed through this time, and memorized the route back.

In his route, most of the people in the village took the empty village.

Most of the villagers have taken refuge in Southbank Town, and some of the village chiefs are orcs, but most of them are human chiefs.

These human village chiefs often return to the village with other village chiefs to jointly develop the village.

Ivan greeted those human village chiefs, and if the Tomorrow City army returned from the liberation of South Bank Town, they would also return to Tomorrow City with the army to report on their work, which was called a reorganization of their positions.

"In all the territory of Tomorrow City, the position of the village chief should be re-established by Tomorrow City, so the village chiefs must return with the army." Ivan said so at the time, and said it every time he passed through a village.

"Lord Ivan, how many meters can our cannons shoot at them?"

The artillerymen ran over and interrupted Ivan's thoughts.

Ivan hummed softly, the first battle of the Liberation War is coming, and he wants to fire the first shot, and he can't shoot empty.

"You can shoot as many meters as you are most sure!" Ivan affirmed.
