From Morgan Guard, east of the Burning Plains, it takes half an hour to ride the Black Iron Dwarf Drill to Blackstone Mountain.

In this half hour, Mishan, who was hugged and protected by Greenhill, enjoyed the pain and happiness very much.

It's not enough to go wrong, this self-control ability Mishan still has.

Besides, it's not **, what are you looking forward to super-expanding, or give up, you're not afraid of 404, someone is afraid......

Along the way, in addition to feeling the soft and warm embrace of Greenhill, Mishan also complained about a black iron dwarf drill by the way, which is not as good as the Titan Ruins Ulduar, those drills made by the Iron Viku and the Iron Dwarves.

If it was the kind of drilling machine that could stuff the steel Viku people, it would definitely not cause the current embarrassment because of the small space.

After a half-hour underground journey, the Black Iron Dwarf Rig took Misr and Greenhill to the side of a wide, paved road at the foot of Blackstone Mountain.

As soon as he came out of the rig, before he could take care of his messy clothes, Mi Shan noticed that the road under his feet was a little strange.

After a closer look, Mishan realized that the road under his feet was made entirely of metal.

It's not rails, it's all metal.

The road, which is about 50 meters wide, is all welded together with black metal sheets that are 10 meters square on average.

"This is the Black Iron Avenue, my lord." Greenhill, who came out together, didn't care about his messier clothes, but tidied up his clothes for Lord Rice Shan first.

"It turns out that the Black Iron Avenue extends all the way to the outside of the dungeon?" Mishan stepped on the ground, making sure that the metal plates that made up the ground were all solid.

"Yes, sir." Greenhill carefully smoothed the wrinkles of Lord Mishan's clothes: "Whether it is the Burning Plains or the Scorching Canyon, including the Black Rock Mountain, it was once the territory of the Black Iron Dwarves. ”

"It's a pity that my own death and the invasion of the orcs have made these black iron dwarves fall to such a point." Mishan, who also knew this, raised his head, looked at the towering Black Rock Mountain, and said to Greenhill, "You put on your armor first." ”

"Yes, sir." Three times five divided by two, Greenhill's "underwear" that conformed to Lord Mishan's aesthetics, and put on the white chain mail.

General Angfu, who had just finished lining up those black iron soldiers, saw this scene, walked over and snorted coldly: "Are you wearing this garbage?" Dragon Slayer? ”

"Or is your master unwilling to get you a better outfit?" After saying that, the Black Iron Dwarven General Anguff also looked at Mishan with sarcasm and contempt.

In Angover's eyes, letting Greenhill, who has the power to slay dragons, wear this equipment is simply an insult to her.

......The tip of the sword, which is less than a millimeter away from General Angover's forehead, shows Greenhill's exquisite combat skills.

Immediately, Greenhill's bone-chilling voice rang out: "Watch your attitude, Black Iron Dwarf. ”

Greenhill's action caused the Black Iron Dwarf soldiers who were already in formation to immediately raise their weapons and aim at Mishan and Greenhill.

General Angover, who was pointed at the forehead by the tip of his sword, hurriedly raised his hand and signaled his soldiers not to act rashly.

The Black Iron Dwarven General felt a murderous aura in Greenhill's words.

General Angover knew very well that if he did anything that disgusted the other party, he might really have to move his head.

"Don't scare these Black Iron Dwarves, after all, what he said is right." Mi Shanfeng, who was being pointed at by a group of black iron dwarf soldiers with weapons, said lightly.

Hearing Mishan-sama's words, Greenhill immediately put away his weapon and returned to Mishan's side, as if nothing had happened before.

Ignoring the fierce eyes of the Black Iron Dwarves, Misr said to Greenhill, "If you can, it's good to get some equipment from the Black Iron Dwarves, there's no need to make the atmosphere so stiff." ”

"What your lord said is extremely ......" No matter what Mishan-sama said, Greenhill first recognized what he was talking about, and then continued: "But with all due respect, my lord, I don't like the equipment made by these black iron dwarves." ”

Greenhill said this without the slightest concealment.

This time, even General Angover couldn't suppress the anger of his soldiers.

You can laugh at our Black Iron Dwarves' past failures, and as a dragon slayer, you can laugh at our Black Iron Dwarves' combat prowess, but what makes you dare to question the casting skills of our Black Iron Dwarves as a human being?

Judging from the reactions of these Black Iron Dwarf soldiers, if Greenhill does not apologize, he will defend the last dignity of the Black Iron Dwarves with his life.

"Hmph...... "If it weren't for Lord Mishan's side, it is estimated that this group of dwarves would immediately pay the price with their lives."

Greenhill, who did not choose violence to solve the root cause of the problem, took out a small piece of what looked like metal from his spacebag-like backpack and threw it in front of the group of black iron dwarves.

Seeing Greenhill's action, Misr raised his eyebrows.

When complaining about the materials science garbage of the world of Azeroth before, Misr and Greenhill mentioned several synthetic materials that are more famous on Earth.

Unfortunately, Misr Shan didn't study much chemistry, and the molecular formula on Earth is not estimated to be universal in Azeroth.

Whether or not we can get those synthetic materials on the earth, Yoneshan is not sure.

Greenhill, who had taken Misuke-sama's words as a holy decree, had been trying to replicate the materials, and the small piece that looked like metal was one of the results.

Even a master craftsman like Greenhill can only make such a small amount, which shows that the process of copying those materials is a long way to go.

But it's enough to take it out and scare these black iron dwarves.

Sure enough, after picking up this piece of iron-like material from the ground and looking at it for a while, the doubts on General Angover's face turned into shock and finally into even greater doubts.

Immediately afterward, those Black Iron Dwarven soldiers who saw this material also fell into a similar situation as their general.

Incomprehensible way of making, incomprehensible intensity, this ...... What the hell is this?

Seeing the reaction of these black iron dwarves, the corners of Mi Shan's mouth curled up slightly.

The metal block thrown by Greenhill is something made of the scientific and technological ideas of the earth's civilization.

When he saw the dwarf engineer hand-rubbing diesel out of oil, Mishan thought of the ethylene industry, the core of the petrochemical industry on earth.

Although Mishan was completely ignorant of the process, it didn't stop Greenhill from trying to figure it out...... It does not prevent Greenhill from rubbing the polyethylene and even the polyethylene fiber by hand.

The little bit of polyethylene fiber is made according to Mishan, and with a bunch of "I think" process, a high-strength polyethylene material that has never appeared on the earth is produced.

Or to put it another way in a more colloquial way, real plastic steel...... God knows how Greenhill made these plastics, which are not very rigid or tough on Earth, so strong.

The result of taking out this piece of real plastic steel that I don't know where it was used for the time being and drying it was that the inexplicable hostility in the eyes of those black iron dwarves disappeared when they looked at Greenhill and Mishan.

If you say it seriously, there is also a hint of imperceptible reverence and curiosity, just like those dwarf engineers before looking at Greenhill.

-----------------------------

World of Warcraft is plastic, which can be purchased in Dalaran, so it can be seen as something that mages make out of their spare time.

By the way, don't take it seriously...... Although the author's life has something to do with the oil industry, it has nothing to do with polyethylene...... It's the kind that doesn't know anything.
