"Can you show us?" Harding looked at Luo Heng with a look of hope.

"It hasn't been made yet. Luo Heng said.

When Sodin and Harding heard this, they were also speechless, Luo Heng pondered in his heart, the manufacture of the steam engine is a little difficult, mainly because the pressure tank of the steam engine is not easy to get.

Relatively speaking, Luo Heng is still willing to make internal combustion engines, not that the scientific and technological level of internal combustion engines is low, but that the parts needed for internal combustion engines are not as strong as steam engines, and steam engines need to drive forging hammers, and the size of the steam engine is not small for a one-ton forging hammer.

"Hey, there's another way to do it. Luo Heng thought in his heart, and his eyes lit up.

Hydraulic forging hammer does not work on the surface, so what about the underground world, there is a dark river in the underground world, as long as you find a dark river with a large drop, not only can you solve the problem of forging, but also in terms of secrecy.

"How long will it take to see that?" asked Thordin.

"It's just an idea, I don't know if Wang Guoyun doesn't allow innovation, and you know that some people are very conservative. Luo Heng shrugged and said.

“......。 Sodin and Harding were speechless, and they asked so much for one thought, but it was impossible for the two of them to say it clearly, after all, Luo Heng had already made a lot of things.

After Harding and Sodin's left, Luo Heng decided to go to the Magicians' Guild to take a look, although Luo Heng knew the materials for the upgrade of the battle armor, but what these materials were.

Even if you look for an underground river, you need a warframe with a strong detection ability, so after the warframe is upgraded, it may be better.

Without bringing anyone, Luo Heng took a magic airship and flew towards the headquarters of the Magician Guild with some vegetables picked.

The first time he took a magic airship, Luo Heng felt bad, and Luo Heng came to the territory at that time.

But this time, Luo Heng felt much better, the magic airship flew not very high, only two or three hundred meters, the magic airship transported some materials, such as letters across the region, letters are small things, and a box can hold a lot of them.

What is left, Luo Heng doesn't know.

"The environment is comparable to a minibus in the fifties and sixties. Luo Heng listened to the whirring wind, and sat on the seat of the hard ~ Bang ~ Bang, and there was a seat belt on the seat, because sometimes when there was a strong wind, the magic airship would be very bumpy like a small boat.

Half of the magic airship is a cargo hold, half is a place to ride, this is a small magic airship, capable of carrying twenty people or a part of the cargo, as for the specific parameters, Luo Heng is not very clear.

Taking the airship, turning three times, flying for a week, crossing more than 20,000 kilometers, and consuming the cost of four hundred gold coins, Luo Heng finally arrived at the area where the headquarters of the Magician Guild was located.

Inside a basin, a hexagonal city, the most obvious symbol is the mage tower on the top of the hill around the basin.

There are hundreds of them, Luo Heng frowned slightly when he saw such terrain.

Luo Heng got down from the magic airship and was checked by the guards, the surrounding crew, Luo Heng didn't know any of them, these people had warriors, magicians, maybe it was a prejudice against the dwarves, these people didn't talk to Luo Heng.

Badge, the coat of arms of the Wizards' Guild.

"Let's go. ”

"Let's go. ”

"The level is too low, go back. ”

A magician constantly checked the badges, some of them were cleared, others were sent back.

"No, Your Excellency, Your Excellency, Listen to me, I'm an auxiliary class, and this is my engineer badge. The repatriated human immediately screamed and pulled out another badge.

"Let's go. After checking, the magician let him go.

Luo Heng muttered in his heart, this is not normal, it is Luo Heng's turn, after the magician checked the badge, he bowed down and said, "Welcome, Your Excellency Cheney." ”

"Uh-huh. Luo Heng nodded, and the people around him looked at Luo Heng differently.

"Laura, Lord Cheney, this is Laura, the apprentice of magic, and Laura will be your guide in the magical holy city. The magician opened his mouth and shouted, and a little girl ran over and looked up at Luo Heng.

"Thank you. Luo Heng was confused.

Laura looked at Luo Heng and said, "Your Excellency, please, I don't know if there is anything you can help Your Excellency?"

"I need to buy some materials, and I need to check my points, and why is the inspection so strict here?" Luo Heng asked, Luo Heng clearly found that he was taking a different path from others.

"Your Excellency, this side of the Magic Holy City is the largest of the five underground world exits in the entire world, and the entire city is a huge seal, and those who are not strict enough will be repatriated, and the other is to prevent the believers of the evil camp from infiltrating it. "Laura looks like she's only a teenager.

"Understood. Luo Heng nodded.

"So is there a detailed description of the Holy City here?" Luo Heng asked again.

"Yes, the Mage Guild has it, and according to the level of the badge, the information obtained is also different, and it can take on different tasks. Laura spoke.

"Then you are also a task to be a guide?" Luo Heng asked.

"Yes. Laura nodded.

Luo Heng looked at the ground, and the stones on the ground seemed to be poured with metal, but it didn't seem to be.

"The entire holy city is a huge seal, the underground entrance is controlled by the Wizards' Guild, there are also the Warrior Guild, the Hunter Guild, the Apothecary Guild, the Forge Guild, and the three major academies, the Mage Academy, the Apothecary Academy, and the Warrior and Knight Academy, and the students here are the best in the entire world. Laura spoke.

Soon Luo Heng saw the Magicians' Guild, all the buildings here had pointed roofs, and there was a section of sharp things on the roof.

"This is the mission hall, this is the employment hall, this is the exchange hall, your Excellency may try this, this is the ...... of high-level magic badges. Laura opened her mouth and said, seeing that Luo Heng was holding the badge and actually penetrated the magic barrier.

Laura hurriedly followed, but in less than three seconds, Laura was inside.

"Stop!" one of the guards shouted coldly.

Laura looked at the guard, nervous, Luo Heng had already spoken: "This is my guide." ”

The guards immediately withdrew their weapons and hid in the shadows, this is also a hall, but the hall here is luxurious.

"Your Excellency. Luo Heng took the badge and came here, and it felt like a café on earth to Luo Heng.

"Check how many points you have. Luo Heng handed over the badge.

"Your Excellency, your points are fourteen thousand five hundred points. The inquiring magician looked at the numbers and was stunned.

"Ah....... Laura exclaimed, then covered her mouth, stunned.

Luo Heng nodded and said, "Give me a copy of the latest information about the underground world." ”

"Your Excellency, your badge is of a high level, please go up to the second floor. The magician said respectfully, stepping out from the other side.

On the second floor, Laura's eyes widened, and seeing that Luo Heng had no objection, she hurriedly stepped forward to follow.

"Oh, dear Cheney, it's great news to see you here. "No sooner had he gone up to the second floor, inside the staircase, than a magician exclaimed.

"Your Excellency, Abel. Luo Heng saw that it was Elder Abel and bowed.

"Great, thanks to your invention, we have achieved a phased victory against the monsters of the underground world this year, and the food production of the entire continent has increased by three times, which allows us to go deeper into the underground world. Abel was excited.

Laura pricked up her ears on the side, and Abel didn't wait for Luo Heng to speak, and said, "Let's go, go up to the fifth floor." ”

"Your Excellency, this is ....... Luo Heng pointed at Laura and spoke.

"Oh, two ladies, your mission is done. Able spoke.

"Yes. The magician who brought Luo Heng up bowed down and replied.

"Yes. Laura also had to take a serious look at Luo Heng, and then left.

Abel Hohan had seen the third, fourth, and fifth floors in the Wizards' Guild branch.

After going up to the fifth floor, Luo Heng found that he could overlook the entire city through the artificial crystal.

"Ryan, see who I'm bringing here?" Abel shouted as he entered a room.

"Cheney, welcome to the Holy City. "Ryan, the great elder of the Magician Guild, is also very affectionate when he sees Luo Heng.

Luo Heng was a little confused, and Ryan personally poured Luo Heng a glass of wine.

"Oh my God, Ryan, you're finally giving up. Abel on the other side exclaimed.

Luo Heng looked at the blue wine, a little puzzled, Ryan said: "Cheney, the dust explosion is too powerful, those monsters hidden in the cave~ hole, just like mice, make us helpless, but now, those monsters no longer dare to hide in those narrow, crooked holes~ holes." ”

"I'm sorry, Lord Ryan, but I don't know much about the underworld. Luo Heng shrugged, and then said.

Ryan was stunned, and even Bernie was taken aback, and asked, "Didn't we tell you?"

"Nope. Luo Heng shook his head and said.

"I'm sorry, I should have let you know earlier, Cheney, this year you submitted a lot of inventions that have had an impact on the whole world, you are fantastic, you have invented farming tools to plough, sow seeds, harvest, and triple this year's grain production, this is the highest harvest ever, and you, Cheney Rowe, will be recorded in history. Ryan spoke.

Abel took a sip of the blue wine, and then said, "Your royal jelly preparation, let's decide to increase the number of places in the Mage Academy and the Pharmacy Academy next year. ”

"Both, what's the matter, please be blunt, we dwarves don't like to be slapped on the back. Luo Heng felt that something was wrong, so he spoke directly.

"Cheney, we want the smelting technology of white iron. Ryan spoke.

When Luo Heng heard this, he was a little incredulous, and Abel said, "Cheney, it's not what you think, white iron smelting and products will only be used in the underground world. ”

"White iron smelting technology is not my own, and I can't make the decisions. Luo Heng shook his head and said.

"Cheney, please take a look at this and then make a decision. Ryan took out a scroll and handed it to Luo Heng.
