Although Donne is very dark and insidious and likes to work in the dark, after all, he is only a serious citizen. He is a little less cunning than night song.

I'm afraid he can't think of it. It's a "separation" with him.

As the night song lifted the separation, the magic mark on the separation disappeared. Of course, Donne couldn't find where the "night song" was.

"This chick... Can actually find that the magic mark can be erased. Look down on her..."

Donne's mouth turned up and showed a very dangerous smile.

"Lord?"

Hilton looked at Donne's smile and felt a little hairy.

"Oh, it's okay."

Donne shrunk his smile and said, "there may be some movement in the business alliance. You should keep unchanged and respond to changes. If there is any emergency, use the transmission array to inform me."

"I see."

Hilton immediately understood that Donne had fallen out with the business alliance.

"In addition, help me keep an eye on the trace of the night song. If that chick appears... Let me know immediately."

Hilton nodded, and then she came back to her senses. The Nightsong that went to the dinner with Donne was gone.

Think of the Lord's very dangerous smile just now

Hilton had a surprise in his heart. Shouldn't the night song annoy the Lord?

Elsa and they had already had dinner. Donne ran to the kitchen to fry some dishes, and then ran to the yard to drink and drink. Only then did he vent his depression calculated by the night song.

The next day, Donne wanted to go around to see if he could find out the night song and teach it. As a result, Fiona suddenly came from Ellington and told Donne an important news. Therefore, Donne had to terminate the plan, take Elsa and Elia out of the city in a carriage, and then secretly use the transmission array to directly return to Ellington.

As soon as he came out of the transmission array, Donne was stunned: "when was a house built here?"

Fiona said angrily, "this is a transmission array. Although you are not afraid to be known by others, do you want to cover it up? Because you don't know what your plan is, you have temporarily covered it with a simple house, waiting for you to plan later."

"There's nothing to plan. Just get an open-air square. Even if it's beautiful, we'll talk about it later."

Don't bother to design so much. Although it would be very beautiful to design according to the scale of the airport and railway station, it's a waste of energy to build it like that. Now he doesn't have so much time to waste on it.

"Well... Oh, we'll talk about it later. Let's get down to business!"

Fiona seemed very excited, but Donne asked her, but she didn't say it. She just waited for him to see it in person, so Donne was also very curious and didn't know what happened.

"Elsa, you and Elia go home first."

"Yes, Lord."

"Bye, big brother ~"

Elia pouted her little pink mouth and kissed Donne on the face, then reluctantly took Elsa's hand and left.

"Well, let's go... Fiona?"

Donne looked at Fiona a little strangely. Why did she look so strange?

The Lord's hobby is really... Very special.

Fiona looked back and said silently, "let's go."

They hurried to Edgar's blacksmith's shop. When they arrived, Brian and Edgar were drinking and celebrating, while the dwarf named Nokia squatted next to them and stared at a pile of metal appliances.

"What's the matter? Did you solve the problem of combine harvester?"

Tang en is also very happy. If the production problem is solved and mass production can be carried out immediately, it can be produced before the autumn harvest. This year's autumn harvest in the territory can save a lot of time, and even let them form a team to harvest in other territories to make money, killing more with one stone.

"Ah? Big brother, you're back!"

Brian laughed and said, "the problem of combine harvester has been solved by master croto and us for a long time. We lack the power of key parts, so we're waiting for you to come back and make a decision."

"Power?"

"Yes, Nokia joined our research after laying the tap water pipe. Later, master kloto came and helped us solve several key problems. But as for the power problem, master kloto thinks it's better to use the dwarf steam engine. We think so, but Lord, you said you want to use the improved magic engine?"

Brian, Edgar and Nokia all know nothing about magic, so they can easily understand the principle and effect of dwarf steam engine, but Donne said before that he has solved the power problem and wants to use the improved magic engine. They can only wait for him to solve this problem.

"Yes, of course you have to use the magic engine."

Donne naturally said, "although the steam engine is good, it has high noise, insufficient power output and serious pollution. I will never use it."

"Lord Donne! You are insulting our scientific and technological achievements!"

Nokia recovered and shouted at a high voice, "dwarf steam engine is one of our greatest inventions! It has brought us great development by leaps and bounds!"

"But the steam age is out of date."

Donne smiled: "even master croto must admit this fact. If you can't solve the power problem of the power source, dwarf technology will stop here."

Nokia was speechless.

"As a matter of fact, I have already told master cloto where to go next. You are also experimenting, aren't you?"

Nokia is a very valuable foreign aid engineer. Of course, don can't beat him too hard, so he said with a smile: "whether it's the internal combustion engine or further excavating the value of magic crystal, it's a good direction, which is more effective than the steam engine. Before that, I think it's better to use my method."

"Well, this is your territory anyway."

Nokia looks much better.

"Then let me see your results."

"Well, big brother..."

Brian scratched his head: "we didn't call you back for that."

Donne was stunned. "It's not because of this? What's that for?"

"It's that."

Fiona pointed to the pile of colorful metal appliances in front of Nokia. Nokia immediately handed over one of the bright silver metal daggers.

"What is this?"

Donne was stunned. The metal dagger didn't look like iron, steel or magic metal like magic iron and refined gold. Its weight was surprisingly light. It was as light as a piece of wood in his hand.

Brian threw out his hand: "we don't know."

"Don't know?"

Edgar scratched his head: "yes, Lord, it was inadvertently made... According to you, it should be an alloy?"

"Alloy? New alloy?"

Donne's eyes widened. "How did you get it?"

Edgar pointed to a test stone made of scrap metal and said, "later, Lord, try this short sword first."

With a gentle stroke from Donne, the dagger easily left a deep mark on the test stone, but the blade of the dagger itself was not damaged.

"Isn't it great? Isn't it?"

Brian laughed wildly, "we were shocked when we found out!"

Donne's eyes lit up: "it's more than powerful! It's going against the sky! Tell me how the alloy was made! Can it be restored!?"

"Of course!"

Brian smiled proudly: "in order to restore the alloy, we worked continuously for a week - no, for half a month!"

Bullshit

Donne laughed in his heart for half a month? He just left Ellington half a month ago, and he didn't hear of it when he came back last time. Obviously, Brian is asking for credit.

"Come on, don't talk nonsense. Good wine is full. There's a big reward!"

Donne stopped Brian's mouth with a word, and Edgar showed a bright smile.

"Sure enough, it's the right choice to follow the big brother!"

Brian grinned and began to explain to Donne how the alloy was discovered.

At first, Brian and Edgar were just playing with the steel made by Donne in their spare time, trying to test the ultimate properties of the steel. The steel that was broken in the experiment was remelted into a furnace of molten liquid by them.

Then an apprentice recruited by Edgar came back from the forest to collect herbs. Before he could go home, he came to the blacksmith's shop with herbs. As a result, his herb bag fell into the molten steel.

The apprentice immediately fished it with a fine gold stirring spoon, but it was too late. The moment the herbal bag went in, it had disappeared.

Later, when the furnace molten liquid was cooled again, Brian and Edgar were surprised to find that the original silver white steel had a blue luster - much like the color of refined gold, but not refined gold.

Later, after tests, the performance of this metal was even better than that of steel!

High strength and toughness!

Brian, they thought it was the herbs. They found the apprentice and asked what herbs were in the bag.

Ash thistle and silver thread.

So they began the experiment.

Then fail, fail, fail all the time

At first, they thought there was a problem with the proportion, confirmed the quantity of herbs and began to retest, but the result was still failure.

Until later, they inadvertently used the refined gold stirring spoon to stir once, and then they were pleasantly surprised to find that they succeeded!

Then Brian weighed it. After stirring with the refined gold stirring spoon, the weight was less and seemed to be assimilated by the molten liquid - but because of the nature of the refined gold, it is impossible to melt it at this temperature!

Then, after many experiments, Brian and Edgar finally determined how to make this new alloy.

Molten steel, ash thistle and silver thread, and then add a small amount of magic metal!
