The steam city is also known as the "heart of the holy city" and is an embedded city.

As we all know, the holy city belongs to a super giant city in the form of a spire. Through the steps of the gods, the holy city (surface part) is divided into four layers from bottom to top:

"my friend" Frankie Kande "hopes that I can help him deal with the problem of efficient and intelligent mechanical Dolls At the same time, my adoptive father, Lindbergh, asked me to bring a message to Mr. Rudolf, vice president of the steam association.

These two are my helpers and will be with me all the way. "

"Verification in progress, please wait..."

About a minute passed.

The robot visa officer in front of him grinned and handed back the knight's medal with a collective temporary pass to ensure that the three were together at any time.

The guards in steam city will check the identity of outsiders at any time, and will be expelled immediately if they can't show their pass.

Next, a series of systemic tests will be carried out to ensure that the entrants are not carrying any pollutants.

Boom ~ riding a horizontal moving machine, it moved about 200 meters between the mountains full of metal frames and steam pipes.

A pure copper gate inlaid with gears appeared.

The large and small gears are indistinctly on the door body to outline the fat portrait of the golden master.

Authentication passed.

The huge copper door broke itself apart.

A trans era steam City unfolds in front of Han Dong.

This embedded city represents the highest technology tree of human race in the current world Without the aid of electric energy, artificial intelligence and efficient energy utilization are realized by steam technology.

All trainee knights and Knights will bring out the pure copper after passing through the fate space, and will be transported here after hand in.

The heavy metal smell has been inhaled into Han Dong's nose for the first time.

However, Han Dong's attention was completely attracted by the beautiful steam City, which, to some extent, completely subverted his views on the holy city technology.

At first, Han Dong thought that with the advent of the end of the world, human beings would survive on the fate space, and science and technology would stagnate.

Facts have proved that, no matter what kind of world, researchers always exist, and will certainly be an important pillar to promote human development.

"My God! Is this the dynamic heart of the holy city? "

Han Dong stood on the outermost metal aisle, overlooking this unparalleled metal city for five minutes.

In addition to using railways and steam locomotives as transportation vehicles, there is also a super efficient aerial vehicle - [rust whale]

an all metal powered airship that imitates the shape of whales.

According to the size and use, there are differences between carrying people and carrying objects.

The most remarkable is the "main heart area" of steam City, which is occupied by only one super huge building.

Heart of eternity.

The power source of the holy city - "the column of steam"

the super huge cylindrical tower building has thousands of pipeline branches at the bottom, which are closely connected with the various buildings in the steam City, just like "tree roots", drawing continuous energy from other buildings.

Its top reaches to the highest point of the inner cave, and further up it will cross the surface and reach the Council area.

Rumor has it that at the top of the column of steam, it corresponds to the treasure house of the gold Lord.

Inside, there are Gold Mountains and silver mountains, in which all valuable treasures are stored. They are used as the big bed for the golden master to sleep.

"This is the steam city. The engineers of holy city have spent nearly a hundred years building and constantly improving their masterpieces The mechanical manufacturing and research being carried out here will become an indispensable part of the great expedition
