From the Morgan post at the south of the Burning Plain, it takes half an hour to get to Black Rock Mountain by the Black Iron Dwarf.

During this half hour, Mi Shan, who was hugged and protected by Greenhill, enjoyed the pain and happiness.

It’s not like a firearm, but Mi Shan still has this kind of self-control ability.

Besides, it’s not **. I’d better give up if I look forward to something that is super expanding. You are not afraid of 404, some people are afraid...

Along the way, in addition to feeling Greenhill's soft and warm embrace, Mishan also complained about the drilling machine of the Black Iron Dwarf, which was not as good as the drilling machine made by the Titan ruins Auduli, the steel Vicu people and the iron dwarfs.

If it were the kind of drilling machine that could plug the steel guardians, it would definitely not be the embarrassment of the current due to the small space.

After half an hour of underground journey, the Black Iron Dwarf Rig sent Mishan and Greenhill to the side of a spacious and flat road at the foot of Black Rock Mountain.

As soon as he walked out of the drilling rig, before he could take care of the messy clothes, Mi Shan found that the road under his feet was a bit strange.

After a closer look, Mi Shan discovered that the road under her feet was completely made of metal.

It's not a rail, it's completely metal.

This road, which is about fifty meters wide, is welded together with ferrous metal plates that are about ten meters square.

"This is Black Iron Avenue, Lord." Greenhill, who came out with him, did not care about his more messy clothes, but first tidied up his clothes for Lord Mishan.

"So Black Iron Avenue extends all the way outside the dungeon?" Mi Shan stepped on the ground and confirmed that all the metal plates that made up the ground were solid.

"Yes, sir." Greenhill carefully helped Lord Mishan smooth the folds of his clothes: "Whether it was the Burning Plains or the Burning Canyon, including Black Rock Mountain, it used to be the territory of the Black Iron Dwarves."

"It's a pity that my own death and the orcs invasion made these black iron dwarves reach such a level." Mi Shan, who also knew these, raised her head and looked at the towering Black Rock Mountain, which was beyond the top, and said to Greenhill: "You put on your armor first."

"Yes, sir." Green Hill's "underwear" that suited Master Mishan's aesthetics was put on another set of white chain mail.

General Angfer, who had just made the black iron soldiers line up, saw this scene, walked over and snorted coldly, "Are you just wearing this piece of garbage? Dragon Slayer?"

"Or is your master unwilling to get you a better equipment?" After saying that, the black iron dwarf general Angfer looked at Mi Shan with sarcastic and contemptuous eyes.

In Angfer's eyes, letting Greenhill, who has the power to kill dragons, wear this outfit is simply an insult to her.

"Clang..." The sword tip, less than a millimeter away from General Angfer's forehead, demonstrated Greenhill's exquisite fighting skills.

Immediately, Greenhill's cold voice sounded: "Attention to your attitude, Black Iron Dwarf."

Greenhill's actions made the black iron dwarf soldiers who had already formed a formation immediately raised their weapons and aimed them at Mishan and Greenhill.

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

The black iron dwarf general felt the murderous aura like substance from Greenhill's words.

General Angfer knew very well that if he did anything that would make the other party disgusted, he might really have to move.

"Don't scare these black iron dwarves, after all, what he said is right." Mi Shanfeng, who was aimed at the weapon by a group of black iron dwarves, said lightly.

Hearing Lord Mishan's words, Greenhill immediately put away his weapons and returned to Mishan's side, as if nothing had happened just now.

Ignoring the eyes of the black iron dwarves, Mishan said to Greenhill: "If possible, it is good to get some equipment from the black iron dwarves. There is no need to make the atmosphere so stiff."

"What sir said is very much..." No matter what Lord Mishan said, Greenhill first admitted that he was talking about, but said, "But I'm blunt, sir, I don't like the equipment made by these black iron dwarves."

Greenhill said this without any concealment.

This time even General Angfer could not suppress the anger of his soldiers.

You can laugh at our Black Iron Dwarf's past failures, and as a dragon slayer, you can also laugh at our Black Iron Dwarf's combat effectiveness, but what makes you a mere human dare to question the casting skills of our Black Iron Dwarf.

Judging from the reactions of these Black Iron Dwarf soldiers, if Greenhill does not apologize, he will use his life to defend the final dignity of the Black Iron Dwarf.

"Hmph..." If Lord Mishan hadn't been by his side, this group of dwarves would have paid their lives immediately.

Greenhill, who did not choose to solve the root cause of the problem violently, took out a small piece of metal from a backpack like a space bag and threw it in front of the group of black iron dwarves.

Seeing Greenhill's action, Mi Shan raised her eyebrows.

When I was complaining about Azeroth World Materials learning garbage, Mishan and Greenhill mentioned several synthetic materials that are more famous on the earth.

Unfortunately, Mishan has never learned any chemistry, and the molecular formulas on Earth are probably not common in Azeroth.

Mishan is not sure whether he can produce the synthetic materials on the earth.

Greenhill, who regarded Lord Mishan's words as imperial edict, has been trying to copy these materials. The small piece that was taken out looked like metal was one of the results.

Even a great craftsman like Greenhill can only create such a little bit, which shows that the process of copying those materials has a long way to go.

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

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

Immediately afterwards, the black iron dwarf soldiers who saw this material also fell into a situation similar to their generals.

An incomprehensible way of making, an incomprehensible intensity, this...what the hell is this?

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

The metal blocks thrown out by Greenhill are made of things made from the scientific and technological ideas of the earth's civilization.

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

Although Mishan knew nothing about the process, it did not prevent Greenhill from trying to make these things... it did not prevent Greenhill from rubbing his hands to make a little polyethylene and even polyethylene fiber.

The little bit of polyethylene fibers produced were produced according to what Mishan said, combined with a bunch of "I'm thinking" processes, and created a high-strength polyethylene material that has never appeared on the earth.

Or change to a more popular name, real plastic steel... God knows how Greenhill made these plastics that are not very rigid or tough on the earth so strong.

The result of taking out this real plastic steel that I don’t know where to use it for the time being was the black iron dwarfs who looked at Greenhill and Mishan, and their inexplicable hostility was gone.

To be serious, there is a hint of undetectable respect and curiosity, just like those dwarf engineers who looked at Greenhill before.

World of Warcraft has plastic, and can be bought in Dalaran, so it can be regarded as something that mages make when they are idle.
