"Lu Xiao, Lu Yi, you two come here!"

Lu Lao raised his hand and beckoned the two apprentices, pointed to the two stoves on the side and said:

"You two go and get a bucket of water and a bucket of oil, fill both buckets as much as you can, and then burn the stove up, preferably looking similar."

When Lu Xiao and Lu Yi heard Lu Lao's arrangement, their faces immediately showed a confused look.

They didn't know what Elder Lu planned to do, but since it was Master's order, they naturally had to obey it unconditionally.

So, the two of them were so confused, and according to Lu Lao's requirements, they prepared everything.

He also lit the stone furnace used to strike iron, and prepared to heat both.

After waiting for the tea, the oil and water in the two cauldrons were boiling.

Lu Lao already knew that mixing the two would have an effect similar to an explosion, so he let his two apprentices stand on a high platform, and put a wooden board under him to resist, leaving only a one-foot-square hole for pouring hot oil and boiling water.

Underneath the hollow is a huge wooden basin.

"You kid, let's say who's going to pour it in first?"

Yang Dong pondered for a moment, although he knew that theoretically, after the two were boiled, they could not be mixed together. But the problem is that he didn't try to pour oil into the boiling water. Instead, he poured water into the hot oil pot, and he didn't know how many times he practiced......

After all, this thing is also one of the basic operations of stir-frying.

"Let's put the oil first."

Yang Dong planned to stabilize his hand first to avoid accidentally overturning.

For his proposal, Lu Lao had no opinion. His two apprentices also knew Yang Dong's ability.

So the two of them stood on the high platform, and the one who carried the oil pot took the lead in pouring the hot oil from the pot into the iron bucket prepared in advance.

The hot oil smoked and was poured into it.

Seeing that he finished pouring it, Lu Yi also picked up the boiling water in his pot and poured it down.

The next moment, there was a "crackling" sound in the iron bucket!

When the hot oil and hot water are mixed, the iron bucket located under the high platform is like a firecracker, and it continues to explode!

This scene instantly stunned the people present!

Even Lu Lao's eyes widened, staring at the situation inside the iron bucket without blinking.

For a long time, he let out a long sigh of relief, but there was a glint in his eyes.

"I see, I really didn't expect such a magical thing to happen!"

At this moment, Lu Lao's admiration for Yang Dong in his heart deepened a little.

Yes, yes, I really accepted a trouble-free apprentice!

Thinking of this, Lu Lao looked at Yang Dong's gaze and became more and more satisfied.

"So the alloy idea you kid just mentioned also originated here?"

"Sort of."

Yang Dong nodded, he didn't explain too much where his knowledge came from.

Seeing this, Lu Lao began to carefully consider the plan for the alloy.

"Is there anything you'd like to recommend about the alloy material?"

Yang Dong pondered for a moment, with a hint of uncertainty in his tone.

"Some metals are hard in nature but not very malleable, and some are the opposite. If we can combine the two, maybe we will have a solution to the matter of boiling water. ”

Lu Lao nodded, this time, his thoughts were the same as this kid. But that's fine, at least prove your ideas and not deviate.

And after Yang Dong hollowed himself out again, he knew that this time Lu Lao was only a matter of time to break through the steam technology.

And the coalition forces are now eyeing each other.

Yang Dong didn't like the feeling of being held a knife to his neck, so he simply continued:

"The steam engine is a very powerful thing, and if it is built, it will completely change the world. But before we do that, I think we should plan ahead for something that is very important to go along with it. ”

Yang Dong said as he took a pen and paper from the shelf on the side.

After he wrote and painted, he handed the sketch in his hand to Lu Lao.

After Lu Lao took the sketch, there was a trace of confusion on his cheeks.

After looking at it for a long time, he asked in disbelief:

"You want to build a carriage? But with so many wagons behind to store goods, how many horses do you have to pull them? ”

"Besides, if there is a turn, most of these goods will definitely be destroyed!"

"Boy, this time your idea doesn't seem to be feasible."

Yang Dong shook his head slightly, pointed to his sketch and said:

"Lu Lao, think about it from a different angle. If we succeed in building a steam engine, will it be possible for it to replace horses? ”

"And although these carriages pull a lot of goods, as you just said, if you make a turn, it can easily cause a huge accident."

"But Lu Lao, have you ever thought that if you give these carriages and put them all on a special track?"

In this way, when encountering a river and a rugged mountain road, you can also build a bridge or make a hole, and no matter how bad it is, you can bypass it. In this case, is it possible for this car to be realized? ”

Lu Lao fell silent, he stared at the sketch for a long time, and the flame in his eyes became brighter and brighter.

Yes, if this behemoth is placed on the track, it will be like the straight road of Daqin and the high-speed official road of Dazhou now.

In this way, the potential of this thing is endless!

When the time comes, only one car is needed, which is enough to replace a baggage team of hundreds or even thousands of people! And it's very expensive and doesn't need to be supervised by as many people.

While improving transportation capacity, it can also greatly reduce labor loss.

If it is put in the midst of war......

Lu Lao didn't dare to continue thinking about it, because he was surprised to find that this thing was completely a weapon specially created for war!

As long as the other party can't destroy the track, then Da Zhou will have terrible logistical capabilities!

As the so-called soldiers and horses do not move the grain and grass first, since ancient times, when the army marches, grain and grass are the top priority.

And many times, the reason for the retreat of the army is not because it cannot take the enemy, but because there is a shortage of food and grass.

Just like the situation in Xiongguan this time, if there is a very complete logistics system behind those coalition forces, then it is impossible for a brave army alone, even with the help of artillery battles, to hold ten times as many enemy troops!

Thinking of this, Lu Lao looked at Yang Dong beside him in disbelief, and couldn't help asking:

"Boy, are you all planned?"

"These techniques taken out now, if everything goes well, after the spring flowers bloom next year, those rebels will not be able to pose any threat to Da Zhou at all!"
