The combat power of level 100 has exceeded 100 million. Am I qualified?

Arnold nodded quickly:

"Ah, yes, yes, what I want to study is exactly what you are talking about."

"Sir, you really hit the nail on the head."

"My lifelong pursuit is to study the kind of magic device you mentioned, even if it is only level 1, it can kill enemies across levels."

Ye Chuyun narrowed his eyes.

Arnold didn't say the words to kill the gods.

Is it because he doesn't dare?

"Arnold, can your flying boots be mass-produced?"

Ye Chuyun asked the question he wanted to ask the most.

After all, flying equipment was very rare even in the past. As soon as it appeared, it would be snatched up.

If these flying boots could be mass-produced, it would definitely be a very remarkable thing.

Who knows, it might become one of his trump cards in the future competition with other forces.

Unfortunately, Arnold shook his head:

"These flying boots cannot be mass-produced for the time being."

Ye Chuyun's eyes flashed with disappointment when he heard this.

"Why can't it be mass-produced?"

"There are two. One is the material for making flight boots. One of them is a ore called fire copper. It is very rare and precious, so it cannot be mass-produced."

"Fire copper?"Ye Chuyun's eyes flashed with surprise.

Isn't this a coincidence?

There is a fire copper mine in the poisonous fog swamp.

The thing that is most in short supply is fire copper.

Ye Chuyun immediately said:

"There is no need to worry about the fire copper problem, what is the other reason?"

"Another reason is fuel."

"The fuel that keeps the flying boots flying is made of magic essence. Although magic essence is not as rare as fire copper, its value is also quite precious."

""Magic essence."

Ye Chuyun nodded in understanding.

Magic essence is the essence extracted from magic crystals.

Ten magic crystals can only extract about 100ml of magic essence.

"But since you said there is no need to worry about the fire copper, I will continue to research and see if there are other fuels that can replace the magic essence."

"Arnold, besides flying boots, what other magical devices have you invented?"

Hearing this, Arnold looked at Ye Chuyun embarrassedly.

"Apart from the flying boots and the combat robot, the rest are just trivial gadgets."

"Ah, this."Ye Chuyun looked at it in surprise.

Logically speaking, if one could become a master of engineering, it would be unreasonable if he didn't invent some amazing magic devices.

For example, in his previous life, there was an engineering master named Feimu who built a teleportation tower for instant teleportation across regions. For a time, he was in the limelight and was robbed by all major forces.

Several other well-known engineering masters have more or less invented some amazing magic devices.

In his opinion, flying boots and the combat robot are not enough to make Arnold a master of engineering.

But this seems a bit contradictory.

"Then where did you get the title of the Grandmaster of Engineering?"

Arnoel shook his head.

"After being controlled by Tiandao, most of my memories of engineering inventions were taken away."

"What is preserved is only some experience in engineering."

"These flying boots, robots and other inventions were all developed after I was controlled by Tiandao."

"So that's it."

After listening to this, Ye Chuyun suddenly realized.

For example, if he was a forging master.

Then Tiandao took away all the equipment drawings he had learned in order to be promoted to the forging master, or the memory of his own original equipment. What was left was only the success rate of forging equipment owned by the forging master.

The same is true for the engineering master.

Except for the success rate, nothing else was saved.

Tiandao, you really know how to play.

But even so, Arnold still made a lot of money for him.

Even without the memory of all inventions, only retaining the success rate of production as an engineering master is also very good.

In the world of gods and demons, there are many life professions that can be taken.

For example, alchemy, forging, alchemy, chefs, merchants, etc.

At the beginning, most people would choose alchemy, forging and other life professions that make money quickly.

Few people choose engineering, almost no.

However, as the internal circulation of popular life professions such as alchemy and forging became more and more serious in the later period, some people chose other unpopular life professions.

At this time, engineering gradually grew stronger.

Then someone discovered the importance of engineering.

Some people can rely on engineering to make special bombs, grenades and other offensive weapons.

Some people even make strategic weapons such as cannons and crossbow carts.

The most important thing is that engineers can also make mounts.

It's similar to the flying boots developed by Arnoel.

The world of gods and demons is so big that there can be 10,000 regions alone.

Obviously, running on your legs will be very tiring.

But it is very difficult to get a mount.

Unless you have the talent to control beasts, you can tame fierce beasts as your mount.

Or equipment like wind feather wings exploded.

Otherwise, there is no other way to get a mount.

Therefore, engineering is particularly precious.

As long as you can get the design drawings, or do your own research like Arnoel, you can produce mounts in large quantities.

So even if Arnoel was extracted by Tiandao from all his previous memories of engineering inventions.

Now that he has developed flying boots, it is very precious to Ye Chuyun.

Thinking of this, Ye Chuyun seemed to suddenly remember something and said to Arnoel:

"Arnold, do you know the Holy City of Ten Thousand Daos?"

"Wandao Holy City?!"

Hearing these four words, Arnold immediately became excited.

"Of course I know, that's the place I dream of."

"What if I could let you into the Holy City?"

"Let me enter the Holy City?"

Arnold looked at Ye Chuyun in disbelief.

"Is this... is this possible?"

"That is the Holy City of Ten Thousand Daos. For us engineers, alchemists, forgers and other professions, it is like a holy place."

"Could it be that, sir, you know how to enter the Holy City?"

Ye Chuyun nodded:

"Of course I know. Just tell me whether you want to go or not."

"Yes, of course I did."

"Okay, then you can just focus on studying these flying boots. When we can enter the Holy City in the future, I will take you with me."

""Okay, okay, sir, don't worry, I will do my best to ensure that these flying boots can be mass-produced!"

Arnold was now in an extremely excited state, and finally kept repeating the word"holy city".

Ye Chuyun was not surprised at all.

Wandao Holy City is a big secret in the world of gods and demons.

Even in the previous life, not many people knew about it.

Generally, only the core figures of the first-rate forces are qualified to know.

However, even if they know the existence of Wandao Holy City, only a very small number of top forces have the ability to try to enter.

The reason why Ye Chuyun knew Wandao Holy City was because the second-rate force [Shadow] he belonged to in his previous life had entered it.
