Rudolph sat on the chair with a confused look on his face, and looked at the picture Diccao in front of him on paper with Nydya.

Dikao explained while drawing: "The most important thing about a motorcycle is the engine, and if it wants to make it have the motivation to run forward."

"I can probably see it clearly here." Niteya pointed at Dikao's drawings, and then slowly moved down with her white and slender fingers. "But I don't understand very well here, why are there many?"

"Oh, this is a cylinder." Dikao explained, "Don't worry about it for now. The main function of this is to suck air from here to help the flame burn. The power generated by the combustion pushes this thing called the 'piston' downwards, so that the shaft below can rotate, and then..."

Dikao explained while drawing pictures, so this can be explained in a little more detail.

After all, I liked motorcycles and cars in my previous life, so I learned more in detail.

Netiya and Rudolph listened to Dikao's explanation and asked questions from time to time that they didn't understand...

After chatting for a whole afternoon, the two of them probably understood how this thing works.

Seeing that the time is almost over, Dikao is planning to go back, "Rudolph, it will be of great use to ask the people below to build more telegraph machines and signal towers recently! As for this thing, you two will think about it first when it's okay."

"As for your order!" Rudolph nodded and responded.

…………

Night falls, and a bright moon hangs in the dark blue sky. Tonight's moon is very round and bright, making the visibility in the forest more than usual.

Mischelia and the elders of her clan were sitting on a tree and chatting.

"I like this city very much." Mischelia leaned against the tree trunk. "How do you think you will live here in the future? You don't have to migrate often."

"It's good not to migrate, life can be more stable." The second elder Salint replied.

The third elder sitting on the branch nodded: "I agree."

The fourth elder Sha Bolina raised her head: "The Demon King must have a requirement, right?"

"Yes!" Mischelia nodded, "He asked us to obey him."

"Impossible!" The Great Elder Torea refused without thinking, "Once the soul contract of the demon clan is signed, we cannot regret it. Once he is pretending to be like this, then we..."

"I agree!" The third elder nodded.

"I also talked about this issue. He said that this can be added to the contract." Mischelia explained, "If he changes in the future, the contract can be automatically terminated."

"If that's the case..." Shaberina thought for a while, "It's not impossible..."

"I reserve my opinion, I always feel that it's not safe." Salint shook his head.

"Actually, what I'm worried about is another problem." Mischelia changed her posture. "For thousands of years, we elves have survived like this. It doesn't matter if we suddenly change our lifestyle, but if something happens in the future, it may not be so easy to change back."

"I agree!" The third elder nodded.

"Then why don't you refuse him?" Shablinsha turned her head, "Summer is coming anyway, so we can continue to live in the forest."

"But we have to migrate again in winter, right?" Mischelia turned her head, "In the past, we didn't have that condition and couldn't coexist with other races, but now it's different. There's a chance now."

"The patriarch wants to agree to him?" Salint asked.

"I think you can try it." Mischelia nodded, "Anyway, one is added to the contract, and as long as he changes the status quo, it will be automatically terminated. You can also add an insurance policy to us."

"I agree." The third elder nodded.

"I keep it." Salint said.

Torrea didn't say anything, and Shaberina smiled indifferently, "Just as long as the patriarch decides."

…………

Dikao issued an order to produce multiple telegraph machines and signal towers to the factory for the subsequent development.

No one can guarantee how long Bilar, who was pretended by the Shadow Demon, could not be discovered, so at the suggestion of Nydya, Dikao must speed up the progress as much as possible while ensuring safety.

And now, the time is almost done.

Although there is no way to obtain specific information within the church, based on numerous analysis of the situation, Augustine is obviously disappointed with the new priest of the church.

But if I think about it from the perspective of others, Dikao felt that if he had been himself, he would have been disappointed.

The factory started the production according to Dikao's orders, while Rudolph and Nitia were hanging in the laboratory together with the engine drawn by Dikao to discuss with each other.

"Are we going to try it now?" Rudolf asked.

"Yeah!" Niteya nodded with a lollipop in her mouth, "Only by trying more can you see better results."

"Then I'll build a shelf like this first," Rudolph stood up, "By the way, how thick is it?"

"What does it mean?" Nitia looked up.

"Didn't my king say there can be more than one cylinder?" Rudolf asked, "Then how many cylinders should we make?"

"Well..." Nitia thought for a while, "It's not interesting to have too few, just twelve!"

"Okay, then you can confirm the size and I'll make the rack first." As he said that, Rudolph turned around and was about to leave.

"Don't worry! This thing is very troublesome. Let's use wood to make a solid model first." Nitia moved the lollipop in her mouth, "It will be convenient to debug wherever there is more and less."

He did it right away, Rudolph directly found a lot of wood and started beating Nitia in the laboratory.

Dwarves are not particularly powerful carpenters because they can't tell the difference between different woods.

But if you just make a model, it is not too difficult for Netiya or Rudolph.

When the sky began to turn white, an engine model with twelve cylinders had been made.

Niteya yawned, took out two bottles of blue potion from the shelf next to him and handed it to Rudolph, opened it and drank it all.

The next moment, the sleepy face immediately became energetic.

Then the two began to look at the model on the table.

"Look, this thing called the piston should be moving like this." Rudolf grabbed one of the wooden pistons with one hand, "According to my king's words, it will push the axis below to rotate."

"Then he has a problem with his picture." Niteya narrowed her eyes, "I feel like this will waste a lot of cylinders."

"How to say it? Isn't this how the picture is drawn?" Rudolph asked leaning over his head.

"Maybe it's the problem with the drawing..." Nitia shook her head and picked up a wire next to her and twisted it. "After all, this drawing is flat, and it's hard to show a three-dimensional thing. You can remake this model of the axis and make it like this."

When Rudolph saw that the original wire had changed its appearance in Nitia's hands. It was not only curved in the upper and lower directions as it was drawn on the drawings, but also added the other two directions to become three-dimensional. If you look vertically, it will be a cross shape.

"Okay, I'll do it right away."

…………

Augustine sat on the sofa, looking at the blue sky outside the window, her eyes were silent and motionless.

A maid walked in and whispered to him twice, "Your Majesty, Your Majesty..."

"Hmm?" Augustine turned her head, "What's wrong?"

"Your Majesty, the priest asks for his visit."

"Call him in." Augustine waved his hand, thought for a while, and then reminded him, "Come here for two cups of tea."

The maid bowed and said she was leaving. After a while, Masville, dressed in a white robe, walked in: "Say to you, Your Majesty!"

"Masville, your plan failed!" Augustine looked expressionless.

"At present, yes!" Masville nodded generously and then sat down on his own.

Augustine didn't care about his rude behavior and still looked out the window: "I seem to overestimate you. At that time, Bernice told me that she could beat Dicao and promised me Dicao's territory; you promised me that you could do it, but I lost another thousand people... Do you have anything to say to me?"

The tone of these words was very calm, but the anger contained in it was as real.

"Don't worry, your majesty." Masville took a deep breath and showed a confident smile. "There is still another way."

"What I fear most now is this sentence." Augustine shook her head, "My expectations have been worn out by you!"

"Your Majesty, this is not our problem," Masville's smile remained unchanged. "This proves Dikao's difficulty."

"It's indeed not a problem for 'our', it should be a problem for 'you'!" Augustine turned her head, "Whether Dikao is difficult or not, this is what you should have investigated clearly at the beginning!"

"He is an alien, your majesty!" said Maswell. "At the beginning, he was just a first-level little demon entrenched outside the five empires, but no one would have thought that he would do so many actions that were not in line with the common sense of the demons."

"Don't conform to the common sense of the demons?" Augustine asked back, "Then is this my fault?"

"Your Majesty, don't be angry," Masville's tone was still slow. "This is something that neither of us would have thought of, after all, no one wants to see this result."

"Okay, don't talk about these!" Augustine nodded, "Then you can come up with a solution! I believe you know what happened in Sunshine City in the past three months, and then? Have you taken any action?"

"Your Majesty, the Paladin is used to deal with the demons." Maswell explained, "But these troublemakers are obviously humans..."

"How do you know?" Augustine asked.

“Because their behavior patterns are…”

"Ah..." Augustine sighed and shook her head, "Prince, I will ask you now. Do you think our cooperation can continue at this point?"

"Of course!" Masville nodded, "It would be better to say that now is the time for us to fight against foreign enemies together!"

"Confrontation together?" Augustine suddenly grinned, "Now that Sunac City is in such chaos, how can it be fought? There is no extra army to attack the Holy City, how can it be fought?"

"Your Majesty, the church still has me!" Maswell shrugged, "I am also a third-level life."

"And what?" Augustine asked, "what can you fight against Dikao, what should he do with his army? Now there are no more troops in Dilanta fighting him."

"Then are you going to give up?" asked Masville. "Now that Sunshine City is in chaos, you can imagine that it will take not long for Dikao to attack Dilanta. Do you have to watch the country fall into his hands? You can watch yourself become the king of the devastated country?"
