Although Tang En is very dark and insidious, and likes to play black hands in secret, he is still just a good citizen after all, and he is still a little less cunning than Night Song.

I'm afraid he couldn't have imagined that there was actually a "clone" next to him.

As Nightsong disarmed the clone, the magic mark on the clone disappeared, and of course Don couldn't find where the "Nightsong" was.

"This chick...... I can actually find that the magic mark can be erased, and I underestimate her......"

The corners of Donn's mouth curled, and a very dangerous smile appeared.

"Your Excellency?"

Hilton looked at Don's smile and felt a little hairy in his heart.

"Oh, it's fine."

Tang En restrained his smile, and then said: "There may be some movement on the business alliance's side next, you should respond to all changes with the same, if there is any emergency, use the teleportation array to notify me." ”

"I see."

Hilton immediately understood that Done had fallen out with the business alliance after all.

"Also, help me keep an eye out for the traces of the night song, if that chick shows up...... Notify me immediately. ”

Hilton nodded, and that's when she came to her senses, and the night song that had gone with Don to the dinner party was gone.

I remembered the very dangerous smile of the lord just now......

Hilton's heart struck, couldn't Night Song be angry with the lord?

Elsa and the others had already had dinner, and Don ran to the kitchen to fry a few dishes, and then ran to the yard to drink and drink himself, so as to vent the frustration of being calculated by Night Song.

The next day. Don wanted to wander around to see if he could get the night song out and train it, but Fiona suddenly arrived from Ellington. Told Don an important news, so Don had to terminate the plan, take Elsa and Ilia out of the city in a carriage, and then secretly use the teleportation array to go directly back to Ellington.

As soon as he came out of the teleportation array, Tang En was stunned for a moment: "When did you build a house here?" ”

Fiona said angrily, "This is a teleportation array!" You're not afraid of being known, but why don't you cover it up? I didn't know what you were going to do, so I used a simple house to cover it for the time being. I'll wait for you to plan later. ”

"There's nothing to plan, just make an open-air square, even if it wants to be beautiful, you have to talk about it later."

Don is too lazy to design so much. While it would have been nice to design for the scale of an airport and a train station, it would have been too much effort to build like that, and he didn't have that much time to waste on it now.

"Okay...... Oh, that's later. Let's get down to business! ”

Fiona looked excited. But when Don asked her, she didn't say anything, just waiting for him to see it in person, so Don was also curious and didn't know what was going on.

"Elsa, you and Elijah should go home first."

"Yes, my lord."

"Big brother goodbye~"

Illya pursed her pink little mouth and kissed Don on the cheek, before reluctantly taking Elsa's hand and leaving.

"Alright, let's go...... Fiona? ”

Don looked at Fiona a little strangely. Why is her look so strange?

The lord's hobby is indeed ...... It's special.

Fiona retracted her gaze and said silently, "Let's go." ”

The two hurried to Edgar's blacksmith's shop. When they arrived, Brian and Edgar were drinking and celebrating, while the dwarf named Nokia was crouched and staring at a pile of metal utensils.

"What's wrong? Is it to solve the problem of combine harvesters? ”

Tang En is also very happy, if the production problem is solved, if it can be mass-produced immediately, and it can be produced before the autumn harvest, the autumn harvest in this year's territory can save a lot of time, and even let them form a team to harvest and make money in other territories.

"Huh? Big brother, you're back! ”

Brian laughed and said, "The problem of the combine harvester has already been solved by Master Klotto and us, and we are missing the power problem of the key part, just waiting for you to come back and make a decision." ”

"Power?"

"Yes, Nokia joined our research after laying the water pipes, and later Master Klotto also came and helped us solve a few key problems, but regarding the issue of power, Master Kloto thinks that it is better to use a dwarf steam engine, and we think so too, but Lord Lord, you said that you want to use an improved magic engine?"

Brian, Edgar, and Nokia, they all don't know anything about magic, so it's easy to understand the principles and effects of the dwarf steam engine, but Don had said before that he had solved the power problem, and that he wanted to use a modified magic engine, and they would have to wait and see if he had to solve this kind of thing himself.

"That's right, of course you're going to use the Magic Engine."

Tang En said as a matter of course: "Although the steam engine is good, it is noisy, the power output is insufficient, and the pollution is serious, so I will never use it." ”

"Donne-sama! You are insulting our scientific and technological achievements! ”

Nokia came back to his senses and shouted at a sharp voice, "The dwarf steam engine is one of our greatest inventions!" It has brought us a great leap forward! ”

"But the age of steam is outdated."

Tang En smiled slightly: "Even Master Kloto must admit this fact, if you can't solve the power problem of the power source, the dwarf technology will stop there." ”

Nokia was speechless.

"Actually, I've already told Master Klotto where to go next, and you're experimenting, aren't you?"

Nokia is a very valuable foreign aid engineer, of course Don can't hit him too hard, so he said with a smile: "Whether it is the internal combustion engine, or to further tap the value of the magic crystal, it is a good direction, this is more effective than the steam engine, before that, I think it is better to use my method." ”

"Well, this is your place anyway."

Nokia's face looked much better.

"Then let me see what you do."

"That, big brother......"

Brian scratched his head, "We didn't call you back for this." ”

Tang En was stunned for a moment: "It's not because of this? What's that for? ”

"That's it."

Fiona pointed to the pile of metal tools of various colors in front of Nokia, and Nokia immediately handed over one of the bright silver metal daggers.

"What is this?"

Tang En was stunned, this metal short sword didn't look like iron or steel, nor was it magic metal like magic iron and fine gold, and its weight was surprisingly light, as light as a piece of wood in his hand.

Brian stretched out his hands: "We don't know. ”

"Don't know?"

Edgar scratched his head, "Yes, my lord, this was made by accident...... According to you, this should be an alloy, right? ”

"Alloy? New alloys? ”

Done's eyes widened: "How did you get it?" ”

Edgar pointed to a knife stone made of scrap metal next to him and said, "I'll talk about this later, Lord Lord, try this short sword first." ”

Tang En stepped forward and swiped slightly, and the short sword easily left a deep mark on the knife test stone, but the blade of the short sword itself was not damaged at all.

"Amazing, right? Right!? ”

Brian laughed wildly, "We were stunned when we found out! ”

Tang En's eyes lit up: "It's not just amazing!" It's going against the sky! Tell me how this alloy was made!? Can it still be restored!? ”

"Of course you can!"

Brian smiled proudly: "In order to restore this alloy, a few of us worked without sleep for a full week - no, half a month!" ”

......

Don En smiled secretly in his heart, half a month? He had only left Ellington half a month ago, and he hadn't heard of it the last time he came back, so it was clear that Brian was asking for credit.

"Okay, don't talk nonsense, the good wine is full, and the bounty is big!"

Don gags Brian with a word, and Edgar smiles brightly.

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

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

At first, Brian and Edgar were just tinkering with the steel that Donn had made in their spare time, trying to test the various extreme properties of the steel, and the steel that had been broken in those experiments was remelted into a furnace of molten by them.

Then one of Edgar's apprentices came back from picking herbs in the forest, and before he could get home, he brought them to the blacksmith shop to work, but accidentally his herb bag fell into the molten steel.

The apprentice immediately used the Adamantite Stirring Spoon to fish, but unfortunately it was too late, and the moment the herb bag was entered, it was already gone.

Later, when the furnace melt was recooled and formed, Brian and Edgar were surprised to find that the original silvery-white steel had a blue sheen - much like the color of adamantite, but not adamantite.

Later, after testing, the properties of this metal were even better than steel!

High strength and toughness!

Brian thought it was because of the herbs, so he found the apprentice and asked what herbs were in the bag.

Gray thistle and silver thread.

So they started experimenting.

And then fail, fail, fail all the time......

At first, they thought it was a problem with the proportions, but they confirmed the amount of herbs and started to re-try, but the results still failed.

It wasn't until later that they inadvertently used the Adamantite Stirring Spoon to stir once, and then they were pleasantly surprised to find that they succeeded!

Brian then weighed it, and after the Adamantite Stirring Spoon was stirred, it weighed a little less, and seemed to have been assimilated by the molten liquid - but with the nature of Adamantite, it was impossible for it to melt at this temperature!

Then, after many trials, Brian and Edgar finally figured out how to make the new alloy.

Steel melt plus gray thistle plus silver thread, then add a small amount of magic metal, and you're done! (To be continued.) )
