"Is this the legendary cement?"

Weilu came forward, picked up a small amount of gray powder with his fingers, then rubbed it, feeling the remaining warmth.

"Lord Marquis, is this thing really as magical as you say?"

"certainly."

Showing a confident smile, Owen believed in the technological power of Winster's world.

In order to convince Viru, he first asked the porter to move three large pieces of rough stone from the quarry, and then instructed the handyman to mix a certain amount of cement with river sand in proportion to make cement mortar.

The cement mortar is gray overall and flows like a melted candle.

The rough stones arrived quickly, and Owen took Viru and Mapel to the outside of the cement workshop. Pointing to the three rough stones, he asked Viru to try to use the prepared cement mortar to bond the rough stones together.

.

This was an order from the Marquis, and Weiru couldn't refuse it, so he could only carry the cement mortar over.

He poured a layer of cement on the largest piece of rubble, placed a piece of rubble on it, then applied the remaining cement and fastened the last piece of rubble.

After finishing, Viru still looked at Owen with suspicion.

"My Lord Marquis, I feel like this thing is like wet mud. Even if it dries, it will break into pieces with just one tap."

"When it dries, you'll definitely change your mind."

According to Winster, cement takes about eight hours to set.

Therefore, Owen asked Viru to go back to the northern city wall to continue supervising the repair work of the gap. He would wait until dusk to confirm the effect of the cement.

In the next time, Owen plans to continue firing cement, since he still has plenty of magic power anyway.

But before that, we have to find ways to improve the working environment. It was really too hot during the firing!

After thinking for a while, Owen decided to return to the castle and change his clothes first. The magician's robe was soaked through and felt sticky and uncomfortable.

Returning to the castle, he changed into comfortable clothes and put on a sky blue frost cloak.

This is a high-end cloak with frost magic stone sewn inside. Although the quality of the magic stone is not very good, it can effectively isolate the heat from the outside. It is the favorite clothing of nobles and wealthy businessmen in summer.

Of course, when Winster saw the new magic stone, he immediately booked it as the magic stone for the next transfer. At the same time, he also hoped to send more different magic stones in the future for him to study.

Owen agreed. If the other party can research new uses for magic stones, it will also be beneficial to the world here.

The first batch of cement had been ground by the gravel workers and stored in sacks. Without letting Owen wait too long, the second batch of raw slurry was sent to the firing room.

With the experience of the first firing, Owen's subsequent firings became smoother and smoother each time, and he gradually mastered the key to magic power output, so that each time he consumed less magic power than the last time.

After firing four batches of cement in succession, Owen stopped when he felt that the remaining magic power was not enough to support the next firing.

If the mana consumption in the early firing is the same as the last time, then the remaining mana should be enough to bake another batch of cement.

In other words, Owen's current limit is to fire six batches of cement.

Winster was deeply shocked that so much cement could be produced under such backward technical conditions. In this regard, he couldn't help but exclaim: In this world, magic is the primary productive force!

Unconsciously, it was sunset, and Owen walked out of the firing room and dusted himself off.

He was not sweating profusely due to the heat, but instead felt slightly cool and very comfortable. It seemed that he was doing the right thing by putting on the frost cloak.

After taking off the cloth covering his mouth and nose, Owen said to the handyman on the side: "Let's do this for today. When the temperature of the stove drops down, you go shovel out the last batch of clinker and store it."

"Yes, Lord Marquis."

Mapel came forward from behind, touched her chest and saluted, saying in admiration: "Sir Owen, you have worked hard today."

"As long as it's for Border Guard Town, it's not hard to do anything." Owen responded.

On the other side, Weiru also finished his work on the northern city wall and hurried to the cement workshop.

It was time to confirm the effect of the cement. Owen walked outside the workshop and saw that the cement was already in a solidified state. The surface was uneven, with white frost appearing in some places. The three rough stones looked like they were tightly glued together.

"My Lord Marquis, let me test it for you."

With a look of contempt on his face, Weilu stepped forward and squatted down, trying to break off the two rough stones on the top, but found that no matter how hard he tried, he couldn't break them off. He was so angry that he stood up and kicked a few times hard, but the two stones on top couldn't be broken off.

The rough stones are still glued together and not moved at all.

It was completely different from what he expected, so Weiru put away his contemptuous expression.

Squatting down again, he pressed the cement part with his fingers, then pressed hard with his nails, and finally borrowed an iron shovel from the handyman to pound the cement hard.

Looking at the small pieces of debris on the ground that he had knocked off with great effort, Weiru gave up.

After the test, he ran to Irving with a face full of shock, and praised with great emotion: "Your Majesty the Marquis! You are so great!!"

Huh? Owen was stunned for a moment. Why was the other party so ecstatic?

However, Owen quickly understood. When he first heard about the properties of cement, he was also surprised. Since he had already been surprised, he was naturally very calm now that he saw the effects of cement.

Moreover, as a mason, Viru must know the power of cement better than Owen.

"Cement is the ultimate material that we masons dream of. With it, buildings that used to take years to build can now be built in just a few months, or even shorter."

Viru was dancing and excitedly explaining to Owen.

"Viru, please pay attention to your behavior." Mapel reminded.

Realizing his rudeness, Weiru quickly apologized: "I'm so sorry, Lord Marquis, I was too excited and ended up being a little carried away."

"It doesn't matter." Owen didn't care.

"My Lord Marquis, the cement you invented is really amazing. In the future, you will definitely be praised by our masons."

This is not due to Owen. He is really embarrassed to fully accept Viru's praise.

"It's too exaggerated to sing praises. Moreover, this is not all my credit. I saw the cement formula from an ancient book."

Owen couldn't expose Winster's existence, so he had to use the mysterious ancient book to block it.

"Ancient book?" Weiru touched his chin and felt a little strange, "If it is the content in the ancient book, it means that people in the past invented cement, then why is no one able to make cement now?"

Irving secretly thought that it was not good and he found a loose reason, which was inconsistent with reality.

His mind was running rapidly, and he explained: "That's because the formula in the ancient book has big flaws. Only after my improvement can we create the cement you just saw."

"So that's it." Weiru suddenly realized, "Your Majesty the Marquis, then your achievements are still worthy of our praise as masons."

[You shameless person, you still take credit for the cement in the end.] Winster teased.

【Why not? I am indeed the first person to make cement in this world.】

Finally, Owen asked Viru: "How about it? Now that we have cement, can the two gaps in the northern city wall be repaired before winter comes?"

This time, Weilu patted his chest confidently, his face full of confidence.
