"Thank you, Dad. Luna walked over and hugged her father's broad waist, "I love you." Then he turned to look at his mother, Kayce, and Tim, and a smile spread across his face, "I love you too, including you, Tim." ”

The mild-mannered mother, Messel, carefully prepared a few sets of clothes for Luna and handed them to her arms: "Luna, don't be too naughty there, do you hear?"

"Well, I'll be very obedient. ”

"Goodbye, Kais, goodbye, Tim. ”

"Goodbye, Luna. ”

The meeting point is by the river where the Efal Outpost is located. Linda, Elena, and Carrick, among others, as well as Weimar and Kayce, see off Leah and Luna.

"Come on, Luna. Leah, who was on a horse, leaned over and pulled Luna to her horse, sitting on her chest, followed by a pack of pack horses full of goods.

"Wow, I can finally ride your magic horse. Luna was on horseback, her little face full of excitement, even though the flames had not yet appeared. After their experiments, the flames of the gods do not burn people.

Sir Weimar rode his horse and waved his whip: "Luna, please leave it to you, Lord Leah." ”

"Leave it to me. Leah took Luna's petite body in her arms and looked back at those eyes, "I'll leave it to you here, I'll be back soon." ”

"Drive!"

The horse neighed, and under the gaze of everyone, the pack horse drifted away.

"Luna, want to see my new abilities?"

The wind whistled in her ears, and Leah's red hair fluttered, and since she found the inspiration to harness her divine powers, she had become more and more proficient in her control of divine powers, and thus discovered a second ability.

"New abilities?" said Luna, surprised, "Are you new so soon?"

"I'm just like you, and I'm constantly practicing. Leah's face glowed with pleasure as she clenched the reins in her hand, "Sit down, Luna." ”

With the surging divine power in her body, facing the whistling autumn wind, Liya, who was extremely happy, burst out of her throat with a high-pitched voice: "For Krem!"

As the voice fell, a halo erupted from her body, quickly spreading out. With the ripples of light on the crotch of the red horse and the pack horse's body, a faint white halo flashed on the horse's hooves, and the speed of running instantly increased......

Scenery Ring!

"Whew!" Luna exclaimed excitedly, feeling the autumn breeze blowing in her face, "Lia, this is amazing." Even pack horses have been influenced by you, you are a natural knight!"

Then, Luna clenched her fists in high spirits and shouted, "For Krem, rush!"

The Storm Aura is a continuous ability, and the mana cost is much lower than summoning Koenigsegg, so it lasts longer. It took almost half the time to come to the first line of heaven again than the last time I brought the car.

......

"Alice, bring the connecting rod. We're one last step away. ”

In the open space in front of the stone house, Qin Song smoothly assembled the last part of the steam engine, the connecting rod. Clapping his hands and standing up, he looked at this machine with industrial beauty with satisfaction.

"Qin, is this a tool that can transcend mortals?" Alice was full of curiosity, stroking the parts of the steam engine, from a pile of swords to a patchwork machine, she participated in every process, and was familiar with every process.

Different from the humble juicer and peeler, every part of this steam engine is full of the beauty of lines, which is a special industrial beauty, coordination and perfection.

Qin Song's expression moved, and he suddenly laughed: "Liya and Luna are here!"

Mons was the first to hover and fall from the sky, standing on Qin Song's shoulder. Not far away, Leah and Luna walked over with two horses.

"Hey, Alice, Wise Man!" Luna greeted cheerfully, "We're coming to see you." ”

"Welcome. ”

Qin Song greeted him reservedly, Liya returned the salute elegantly, and her eyes soon fell on the strange metal machine behind Alice: "Alice, this is the big thing you said?"

"Yes. Alice looked at Qin Song with a smile: "This is my joint work with Qin who fought for a day and a night." ”

"Wow, what is this big iron bump?" Curious baby Luna, around the steam engine, curiously touched around, knocking on the iron sheet clanging.

"This is a being that transcends human beings. Alice raised her little face proudly: "The knowledge of boiling water." ”

"What?," Luna glared at her big watery eyes, "Can you have knowledge by boiling water?"

Leah's face was also full of curiosity.

"The knowledge of nature is everywhere. Qin Song smiled slightly: "Alice's divine power allows knowledge to be sublimated and displayed in front of you." ”

Qin Song skillfully opened the water injection port on the boiler and began to add water. Alice, on the other hand, tacitly packed up the firewood and stuffed it into the hearth below.

"It's really boiling water, and I'm here to help. Luna crouches down in high spirits and helps Alice light the firewood in the hearth.

As the fire grew stronger, the steam began to gurgle. Because the joint is perfectly sealed, there is not the slightest steam escape, and the pressurized water vapor is introduced into the cylinder along the air transfer steel pipe.

Estimating that the steam was almost filling the cylinder, Qin Song grabbed the runner with his hand, turned it slightly, and applied the power boost. Then, a surprising scene appeared, the connecting rod began to move spontaneously, pushing the runner to rotate, after reaching the maximum point, the piston reached the bottom, and a burst of hot white steam erupted from the exhaust hole, and the steam on the other side began to fill, pushing the piston back, driving the other connecting rod to make the iron wheel rotate.

Whoop Woohoo ......

The rhythmic sound of steam continued to sound, and as the fire continued to increase, the iron wheel began to spin rapidly, and the sound of metal rubbing creaked because there were no bearings.

Luna was dumbfounded, "This ...... What's the point?"

Leah's face was full of shock, she had seen the whole process of the water burning with her own eyes, and then spinning, and she could be sure that there was no additional power. And just a bucket of water can drive the huge and heavy iron wheel to spin rapidly.

The most exciting thing is Alice, this is a machine she has made with her own hands, and every part is extremely familiar. When they are combined, the power of water and qi that Qin Song said is truly revealed.

"Qin, we succeeded!" Alice cheered, "We can use it to drive the drill bit and drill bigger and better steel pipes!"

"Alice. Qin Song's heart was surging, the steam engine, this epoch-making product, would eventually subvert the pattern of this world. But his face was unwavering: "It can not only be used to drive the drill bit, I can say unceremoniously that it can be used for more than you think." ”

Feeling the breeze set off by the flywheel and listening to the hum of metal, Lia's heart turned upside down, and the power of this pile of iron lumps was incredible.

"Your Excellency, this ...... Things, can you drive a carriage?" said Leah, full of anticipation, and the spinning flywheel made her think directly of this purpose.

"Yes, Leah. Qin Song nodded lightly: "It can not only be used to drive a carriage, but even a chariot." That is, it can replace animal power and manpower, and do it better. All you need is water or fuel. ”

Chariot!

Liya's heart jumped, she knew too well the combat methods of the Knights, and the group charged, invincible. But what if the Knights' opponent is a steel chariot covered with steel spikes? not afraid of death, not knowing tiredness, not retreating, the heavy chariot can completely crush the Knights into meat sauce!

"I remember!" said Luna excitedly, "Your Excellency, your civilization is full of steel creatures that can run on the ground, soar in the skies, and sail in the oceans. This must be the kind of thing you use, right?"

To Luna's surprise, Qin Song shook his head, "Luna, this is just introductory knowledge. The steel we have created is far more powerful than you can imagine. However, don't be frustrated, this is a beautiful start, and in the guidance of knowledge, the near future will become more brilliant!"

"Hah, introductory knowledge??" Not only Luna was surprised, but Alice and Leah were also shocked, this steam engine was enough to subvert their worldview, what would something more powerful look like?

Qin Song slowly closed the familiar valve, started the exhaust valve on the boiler, and the fast-spinning flywheel continued to rotate for a long time by inertia before slowly stopping.

"Leah, the threat of the orcs is near. I feel it. Qin Song's face became solemn: "This machine will make a brand new weapon for us." And, Alice and I, we've already made a prototype, would you like to see it?"

Leah took a deep breath and nodded emphatically, "Your Excellency, I admire your wisdom. Be willing to be baptized by your guidance and witness the greatness of knowledge. ”
