He was a little dumbfounded when he heard this. Then he immediately realized that it was the intelligence agency of Winter City who had inquired about it. He did not hide it and admitted openly:

"Sir Lord, cement can indeed have such a powerful effect, but I have encountered a lot of difficulties now. The key to making cement is the three stages of grinding-burning-grinding. Although I have found a good main ingredient, there is still a lack of

Important ingredients.”

In fact, from the perspective of not doing personnel matters, the main issue is materials.

There is one ingredient that I just can't find, only a little bit of that.

On the contrary, grinding is very simple, just let the player use fighting spirit to crush it and that's it.

"I see. Let me introduce you. This is Nina, the maid of Winter Castle. She has the ability to transform minerals. I wonder if she can help you."

"Transform minerals?"

Idiot stared wide-eyed, looking at Nina who was still a child, thinking what kind of perverted skill is this?

Directly change the chemical composition and physical properties of a substance?

This is equivalent to changing the nature of the world.

Even if the continent of Kane is a Western fantasy world with high martial arts, such skills are still outrageous.

Although he still felt a little unbelievable, looking at the affirmative look in Eagle Lord's eyes, he immediately ran back to his room and took out two kinds of ores.

One type is called gray stone by the slave workers. Its properties are similar to limestone and is the main material for the production of cement, but it also requires many ingredients.

The other type doesn't even have a name. It is mixed in stone by slave workers and has properties similar to marl. It is a brown ore that can be directly fired into cement without any ingredients.

The disadvantage is that the quantity is limited, and the slave workers only found a little bit in the area where the stone was collected, which is not enough to even build a house.

He placed two pieces of ore on the ground in front of Nina, pointed at the two rocks, and introduced them seriously:

"The one on the left is gray-faced stone. There are many in the Sorrento Mountains. The one on the right is named marl. It is very rare. If you can convert the gray-faced stone into marl, then the problem of cement will be solved.

It can be solved."

Nina didn't say anything immediately after hearing this. Instead, she first raised her head and looked at Xi Wei searchingly.

After receiving an encouraging look from the latter, he nodded in front of Wu Shi and said somewhat unconfidently:

"let me try."

As she spoke, Nina knelt down and placed her two white and tender hands on the two pieces of ore respectively. A hazy earth-yellow light lit up in her hands.

Both Wu Shirenshi and Xiwei watched this scene intently and held their breaths.

A magical scene happened. The limestone on Nina's left hand side began to gradually shrink and change color, and finally transformed into the marl stone on her right hand side, which was about half in size.

I guess this kind of loss is the limitation that Nina mentioned before.

"It's really possible!" Bu Shirenshi looked shocked and looked at Nina feverishly, as if looking at a rare treasure.

The person he admired most in his heart was his university professor, the grey-bearded chemical engineering academician, but at this moment, he had already buried the old man in his heart and re-erected the statue of the little girl in front of him on the grave.

.

Nina was a little frightened by the indifferent eyes and hid behind Xi Wei timidly.

Although she knew that these strangers were all subordinates of the lord, she still felt that these people were not normal. Sister Luo Li also often said that you should avoid interacting with strangers, otherwise you might become a fool.

Nina still wants to do things for the lord, and doesn't want to become a fool so early.

The demi-human girl's actions made me realize that I was losing my temper.

He coughed awkwardly and said to Xiwei solemnly:

"Lord, if Nina can convert this marl in batches, then cement can be successfully produced."

Hearing this, Xiwei cast his eyes on Nina beside him and asked:

"Nina, if you transform marl just once, how many times can you do it with your energy?"

Nina pondered for a moment, made a careful calculation in her mind, and said uncertainly: "An ore as big as just now can probably be transformed more than ten thousand times."

Xiwei picked up the mud on the ground and made a rough calculation. The marl in his hand was about 2kg. In other words, Nina could convert 20 tons of mudstone at one time. Taking into account the loss ratio, it would take about 40 tons of ash.

Facing stone.

This output is already terrifying.

Both Xiwei and Bu Shirenshi saw a hint of shock in each other's eyes.

If used to convert into gold...

Xiwei subconsciously wiped a handful of non-existent saliva, then took out a gold coin from his pocket and gave it to Nina, and couldn't wait to order:

"Nina, try converting marl into gold?"

Nina obeyed her instructions and covered the gold and marl with her little hands. After a while, the marl gradually shrank and turned into gold the size of rice grains.

Only the size of a grain of rice...

Xiwei was silent. Why is the loss ratio so high?

But even so, it is still very strong. There is no shortage of rocks in the Kane continent, and so many rocks can be converted into a lot of gold.

Seeing Xiwei's excited expression, Nina seemed to be aware of his thoughts and said with some embarrassment:

"Lord, it seems that the difference between these two minerals is too great, and the conversion consumes a lot of energy. The one just now consumed one-fifth of my energy."

Xiwei: "..."

Five grains of rice-sized gold every day are of no use. It would be better to let Nina convert it into marl for the idlers to make cement.

But not today, Xiwei still had some tests to complete, so he could only leave with Nina with a look of reluctance.

The next thing to test is the metal's ability to fuse.

About this, Xiwei found the blacksmith shop in the outer city.

There is no point in looking for Enzo. Enzo is just a tool man who relies on the system to work. In fact, he doesn't understand blacksmithing at all. He can only knock randomly.

A moment later, the blacksmith shop in the outer city...

"Lord, are you saying that this little demi-human girl can fuse two metals together without smelting?" The gray-bearded old blacksmith's tone was full of doubts.

He has been working in iron all his life, and he has never heard of such a strange thing. However, since it is the Lord's intention, the old blacksmith can only choose to believe it for the time being:

"This is really an incredible thing. If she can really do it, the dwarves who are famous for their forging will go crazy for her!"

As he spoke, the old blacksmith took out a piece of black magic steel from under the pillow of the bed not far behind him. This was his treasure, a gift given to him by his master, a dwarf master blacksmith.

It's a pity that his talent is limited. After a lifetime of hard work, he can only make master-level equipment at best.

This is an advanced forging material made from magic obsidian and meteorite that are smelted at high temperatures and forged tens of thousands of times. The great sword Xiwei is currently using is also forged from this material.

The old blacksmith caressed the black magic steel in his hand as if he were caressing his wife, but he quickly came to his senses, took out a piece of magic obsidian and a piece of meteorite from the forge, and said to Xiwei:

"Lord, you can let her try to see if she can fuse magic obsidian and meteorite into black magic steel."

"Try it, Nina, don't feel pressured."

Despite Xiwei's encouragement, Nina was still a little worried.

Transforming gold previously consumed one-fifth of her strength, which was a big blow to her.

She took a deep breath, stood on her toes, placed the meteorite and magic obsidian on the forging table together, and then stretched out her little hand to cover them.

Compared to the earthy yellow light when the ore was transformed before, the light in Nina's hands now has a metallic luster, and under the influence of her ability, the two ores are making a rapid "buzzing" sound.

The time did not last long, and the meteorite and magic obsidian miraculously disappeared.
Chapter completed!
