When Ye Lao heard this, he was also interested, and said, "What is it?" I wonder if I can take it out and let the old man take a look? ”

Ye Chen took out a wooden box the size of a child's palm from his cuff and handed it to the other party.

Ye Lao raised his hand to take it, and when he opened the wooden box, he saw that there was some gray-white powder in it, and then put it to his nose and sniffed it gently.

Looking up at Ye Chen, he asked, "What is this?" ”

Ye Chen replied: "This is inadvertently figured out, it is made of stone processing, it has a strong adhesive ability, and it is much stronger to use it to pile up bricks and stones than mud and other things." I named it Lime. ”

When designing the house, he naturally thought about the material, so he thought of lime.

In fact, the best material for building a house should be concrete, but at the level of this era, it is still difficult to refine real concrete, so you can only settle for the next best thing and replace it with lime.

After all, I don't want to build any big projects, and this thing should be enough.

Ye Lao looked at the lime for a moment, and then asked, "Can I try it?" ”

Ye Chen said: "Naturally, but this thing is a bit special, let me demonstrate it first." ”

Ye Lao nodded slightly, and then returned the wooden box to Ye Chen.

Ye Chen picked up the box and said, "Please take a container and some water." ”

The former nodded in response, and then brought a gourd scoop with some water.

Ye Chen held the scoop in one hand and poured the lime in the box into it with the other.

Immediately after that, several people saw that the water in the scoop began to bubble, gradually heating up, and even began to boil after a breath.

Seeing this scene, both the onlookers showed doubts and surprises.

Han Fei asked, "Senior brother, why is this?" ”

Ye Chen asked rhetorically: "Do you still remember the water and gold consumption when the ghost soldiers robbed the salary?" ”

Han Fei's face moved, and he said: "Water and gold burn when it meets fire, and it melts when it meets water, which is similar to this thing, and it is all the principle of reversing the five elements......"

As he said this, his eyes flashed, as if he had thought of something, and then said, "Could it be that this lime is made by calcining flames?" ”

Ye Chen raised his eyebrows slightly and said, "How did you know?" ”

Han Fei said: "As the so-called water comes to cover the soil, it stands to reason that the soil restrains water, but now the water is boiling after encountering the soil, as if it is boiled, which is the effect that can only be achieved by fire."

So there is only one explanation, and that is that the thing was formed by incineration, absorbing the energy of the flames, and although it resembles earth, it is essentially fire. ”

Hearing this, Ye Chen's heart was also moved, to be honest, he didn't think so much when he came up with this thing, but now listening to the other party's explanation, he also feels that there is some truth.

However, there is no need to care about what lime is, as long as it can play its due role.

After a while, the level of the boiling lime subsided, and the lime water was divided into two layers, the upper layer was an ordinary liquid that was useless, and the lower layer was precipitated by what could really be used for construction.

After the water is filtered out, the remaining lime slurry is left alone, and then some fine grit is found and mixed together for stirring.

At this point, the simple and practical lime sand is considered to be completed.

Ye Lao stepped forward to take a look at it and said, "Does this thing really work?" ”

"If it doesn't work, you'll find out if you try it."

As he spoke, he found a piece and turned his head, broke it in half, smeared a thick layer of lime sand on half of the bricks, and then glued it back together.

"Is there a stove here?"

Ye Chen asked.

Ye Lao nodded, and then led him to another room.

As soon as I entered the house, I felt that the temperature of the air was much higher, and two feet in front of me was a large stove that constantly released high temperatures, and there were all kinds of metal that had been made next to the stove.

Seeing this scene, Ye Chen asked, "Seniors are still good at forging?" Could it be a swordsmith? ”

Ye Lao shook his head: "I only forged to better understand the characteristics of these materials, and in the process of burning and continuous polishing, many characteristics will be naturally expressed. ”

"I see."

Ye Chen nodded slightly, the person in front of him has quite high attainments in architecture, mechanisms, and forging, and these can be summed up in one direction, that is, creation.

It seems that the other side has come a long way on this path, and the pattern is very large.

Walk up to the red-hot stove and place the bricks on it to heat it up. Under the high temperature baking, in less than two minutes, the lime sand has completely solidified, and the two halves of the bricks are tightly fixed together.

Ye Lao took out the bricks, and then broke them hard, only to see that the joints were still firm, and there was no sign of loosening.

Looking at the lime sand on it, he was also surprised, this powerful solidification ability was definitely not comparable to those muds.

If you use it on top of fortifications, you can definitely build a strong fortress.

looked up at Ye Chen and sighed: "I didn't expect that countless people who have been thinking about things that they have not been able to solve in their lives have been solved by you, and sure enough, there are talented people in the world." ”

"I don't dare to be, it's just through the wisdom left by the sages."

Ye Chen replied.

Ye Lao only thought that he was modest, and didn't say much, and then said: "With this thing, what you want to build will be no problem."

However, the old man can't help in vain. ”

"That's natural, I don't know how much money the seniors want as a reward?"

Ye Chen asked.

"I want this lime making method, are you willing to give it?"

Ye Lao looked at the former and asked.

Ye Chen raised his eyebrows slightly when he heard this, he naturally knew the attraction of lime, but he didn't expect the other party to bring it up so directly.

Just as he was about to speak, Ye Lao smiled and said, "Just kidding, how can a mere house be compared to the value of lime?"

I am satisfied to see this thing today, and as for the payment for its construction, there is no need for it, and the old man is not short of money. ”

Although he had a smile on his face, he still couldn't hide the look of loss in his eyes.

Ye Chen opened his mouth and said: "The predecessors already know that lime is made from rocks, even if you don't understand the specific process, you can always get a result if you spend more time experimenting, why do you want to ask me again?" ”

Ye Lao said: "It's easy to say, but I'm afraid it's not so easy to really want to make it."

Besides, the lime is burned by you, and if the old man takes it as his own without consent, how is it different from stealing? ”
