Killing monsters with a 100% explosion rate, are you luckier than me?

Arnold nodded quickly:

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

"Sir, you really spoke to my heart."

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

Ye Chuyun narrowed his eyes.

Arnall did not say the words "kill the god" after all.

Is it because you don't dare?

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

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

After all, flying equipment was very rare even in the previous life. As soon as it appeared, it would be robbed.

If these flying boots can be mass-produced, it will definitely be a great thing.

Maybe it will become one of his trump cards in future competition with other forces.

It's a pity that Arnold shook his head:

"This flight boot is not yet available for mass production."

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

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

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

"Fire copper?" A hint of surprise flashed in Ye Chuyun's eyes.

Isn't this a coincidence?

There is a fire copper mine in the Toxic Mist Swamp.

The most indispensable thing is fire copper.

Ye Chuyun immediately said:

"Don't worry about the fire copper issue. What's 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 quite precious."

"Magic spirit."

Ye Chuyun nodded clearly.

Magic essence is the essence extracted from magic crystal.

Ten pieces of magic crystal can only extract about 100ML of magic essence.

"But since you said you don't have to worry about the fire copper issue, sir, I will continue to research and see if there are other fuels that can replace the magic spirit."

"Arnall, apart from flying boots, what other magical devices have you invented?"

Hearing this, Anol glanced at Ye Chuyun sheepishly.

"Except for the flying boots and the combat robot, the rest are just some insignificant inventions."

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

Logically speaking, it would be unreasonable for someone to become a master of engineering without even a few earth-shattering inventions of magic weapons.

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

Several other well-known engineering masters have more or less invented several magical devices that defy the heavens.

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

But this seems a bit contradictory.

"Then where did your title of master of engineering come from?"

Arnold shook his head:

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

"What has been preserved is just some engineering experience."

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

"I see."

After hearing this, Ye Chuyun suddenly realized.

For example, if he is a blacksmith master.

Then Tiandao took away all the equipment blueprints he had learned in order to be promoted to blacksmith master, or the memory of his own original equipment.

All that remains is the success rate of the forging equipment owned by the forging master.

The same is true for engineering masters.

Nothing is saved except the success rate.

Tiandao, you really know how to play.

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

Even if there is no memory of all inventions and only the production success rate of being an engineering master is retained, the success rate is still very good.

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

For example, alchemy, forging, alchemy, chef, businessman, etc.

At the beginning, most people will choose alchemy, blacksmithing and other life occupations that can make money quickly.

There are very few people who choose engineering, barely a few.

However, as popular life occupations such as alchemy and blacksmithing became increasingly involved in the later period, some people chose other less popular life occupations.

At this time, engineering gradually grew in strength.

Then someone discovered the importance of engineering.

Someone can rely on engineering to create special bombs, grenades and other attack weapons.

Some people even made cannons, crossbows and other strategic weapons.

On top of that, Engineers can also create mounts.

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

The world of gods and demons is so big that it can be divided into [-] regions.

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 ferocious beasts as your own mount.

Or equipment like Wind Feather Wings was released.

Otherwise there is no other way to get the mount.

Therefore, engineering is particularly valuable.

As long as you can get the design drawings, or do your own research like Arnall.

You can mass-produce mounts.

So even if Arnall was extracted by Tiandao from all his past memories of engineering inventions.

Now he has developed flying boots, which are very precious to Ye Chuyun.

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

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

"The Holy City of Ten Thousand Daos?!"

Hearing these four words, Arnold suddenly became excited.

"Of course I do, that's my dream place."

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

"Let me enter the Holy City?"

Anol looked at Ye Chuyun in disbelief.

"Is this...is this possible?"

"That is the Holy City of Ten Thousand Daos. For our engineering, alchemy, blacksmithing and other life professions, it is simply a holy place."

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

Ye Chuyun nodded:

"Of course I know, just tell me if you want to go."

"I want to, of course I want to."

"Okay, then you can study these flying boots with peace of mind. When you 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!"

Arnall was now in a state of extreme excitement, and finally kept chanting the word "Holy City".

Ye Chuyun didn't have any surprises.

The Holy City of Ten Thousand Daos is a big secret in the world of gods and demons.

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

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

However, even if the existence of the Ten Thousand Dao Holy City is known, only a very small number of top-level players are capable of trying to enter.

The reason why Ye Chuyun knew about the Holy City of Ten Thousand Daos.

It's because the second-rate force [Shadow] he belonged to had entered in his previous life.
