Near Base No. 10, there are a total of five bases, which together form a small Level 4 base cluster.
Strictly speaking, however, they are still in the heartland under human control, an area where the number and level of alien beasts are weakened, and powerful alien beasts can hardly survive for long.
These level-four bases don't even have names; most of them only have a number.
They are like villages and towns in a normal society, not truly providing the basic strength and resources such as population in the front line.
Truly advanced bases are located in areas close to where alien beasts are active or powerful; these are dangerous areas, but also areas extremely rich in resources.
Jiang Ziliu's next destination is a river-lake junction nearly 600 kilometers away from Base No. 12.
There exists a large base here with a population of over three million.
However, this base is only a third-level base under the Chang'an Base, except that a third-level base has a name.
This base is called Lingyan Base.
This base has existed for nearly six hundred years!
It was established under the leadership of a Gold Rank Beast Tamer named Yu Lingyan. During the construction of this Level 3 base, a terrifying beast tide erupted and attacked it. It was Yu Lingyan, the Beast Tamer, who fought a bloody battle against the enemy's high-level Gold Rank beasts and repelled the enemy, allowing the Lingyan Base to be successfully established.
This was an era where individual power was incredibly terrifying. To Yu Lingyan's military achievements, the entire base was later named Lingyan Base.
Base No. 12 has a rock-paved road leading to it, which is nearly 1,300 kilometers long and 100 meters wide, making it a true super highway.
The massive stones used to build the avenue were also five meters long, three meters wide, and three meters thick.
A large number of extraordinary beast tamers cleaved mountains to create roads and paved them with stones, successfully establishing this major road connecting all level-four bases to the Lingyan Base.
The immense power and extraordinary skills of beast tamers and their masters allowed this path to be established at a speed no less than that of the ordinary industrial era.
After humans acquired great strength, their work efficiency became remarkably high.
The construction of such a wide road was also to facilitate the travel of giant beasts.
If it were like the path Jiang Ziliu in his previous life, some large beasts simply wouldn't be able to pass quickly.
The design requirement was to allow the giant beasts to pass through, so each of its boulders must have a load-bearing capacity of hundreds of tons.
After the world underwent tremendous changes, rivers and lakes also expanded significantly.
Humans then used their extraordinary powers and skills to build giant stone bridges across these transformed super rivers.
These stone bridges were also built using massive, tough stones weighing hundreds of tons as bricks, in an extremely rough and simple manner.
Despite its simple structure, its sturdiness and load-bearing capacity are no less than those of steel and concrete bridges.
This is because these boulders are made of a stone that is even tougher than granite.
To build this Eagle Bridge, humans used a large number of Earth Giant Ape reaching hundreds of meters in height.
This beast-taming power ranges from hundreds to tens of thousands of tons, allowing them to easily manipulate rocks and accomplish this task.
The roads throughout the heartland of humanity were all built in this way.
The emergence of beast taming did not reduce human productivity; on the contrary, the existence of extraordinary power and skills greatly expanded human productivity, enabling them to do many things that ordinary technology could not.
Jiang Ziliu didn't delay. Instead, he had the Green-Skinned Shapeshifting Spirit transform into the Wind-Piercing Blue-Feathered Eagle, which flew along the main road all the way to the Level 3 Lingyan Base.
Along the way, he saw caravans of all sizes traveling back and forth, with the main transportation work being carried out by beasts like the Earth Savage Bull.
Some caravans used giant elephants weighing seventy or eighty tons and standing over thirty meters tall for transport.
This behemoth can also carry a load of over fifty tons at a time!
The transport capacity of the beast taming is in no way inferior to the torrent of trucks in his previous life.
It wasn't surprising that the merchants below saw Jiang Ziliu flying overhead with a different face.
As Jiang Ziliu rode on his flying eagle, he also saw many other people riding on eagle-like beasts traveling along this road from the air.
Along this avenue, there is a military fortress approximately every thirty kilometers.
It is the force that maintains the roads.
Near the military fortress, there were also service areas that provided accommodation, food for wild animals, drinking water, and other supplies and services.
The Green-Skinned Shapeshifting Spirit has a B Grade skill called Transform into an Animal, which allows it to transform into a flying eagle and carry Jiang Ziliu through the air.
His journey was very smooth, as human forces were constantly clearing away the threats on both sides of the road.
Jiang Ziliu arrived at the Lingyan Base in less than three days.
This place is far beyond the reach of the Blood Eye Adventure Group, the Elf Race, and the Werewolf Race.
Jiang Ziliu planned to visit the Lingyan Base first before making any further plans.
The walls of the Lingyan Base are 200 meters high and nearly 500 meters wide, and are made of ten layers of interlocking stone bricks!
The entire city wall is 90 kilometers long and 60 kilometers wide.
It was originally only fifty meters wide. It was reinforced layer by layer until it reached its current size.
The construction and reinforcement of the entire Lingyan Base's city walls took nearly fifty years.
This time, Jiang Ziliu used Zhou Xiaoke as an alias. The black market's forgery of documents was very thorough; as long as you could afford it, they could make it flawless and withstand scrutiny.
He successfully infiltrated the Lingyan Base and witnessed its true condition.
The Lingyan Base is very large, but only one-tenth of the area is urban, while the other nine-tenths is agricultural.
The city wall, nearly ninety li long and sixty li wide, was mainly built to protect the plains and farmland within the city.
Unlike other bases, Lingyan Base primarily produces food for humans.
The excrement of these advanced life forms, such as mythical beasts, can be used as fertilizer, even better than chemical fertilizers in my previous life, after processing.
After all, this is a world beyond the ordinary, and many things here are incredibly magical.
This farmland at the Lingyan Base not only meets the basic food needs of the Lingyan Base, but also satisfies the food requirements of more than a dozen nearby level-four bases.
The reason for such high productivity is that everyone has specially contracted with beasts that have life attributes.
This kind of life-related skill for controlling beasts, combined with good fertilizer, can make it possible for the entire base to have four or even five harvests a year!
As long as there is enough feces from the mythical beasts, humans will not have to worry about food shortages.
The Lingyan Base was established at the confluence of rivers and lakes, taking advantage of the grain production potential of this plain.
What humanity truly lacks are the various high-level resources that allow beast tamers to grow and develop.
For example, Elemental Crystal, Soul Crystal, etc.!
Level 3 bases are humanity's true foundational bases.
Level 4 bases are small expansions of the existing human base, mainly to provide basic living space for the gradually expanding population, and also to enhance the Human Race's war potential in order to deal with the threats of various alien races and beasts.
Lingyan Base is also a special fortress, and it has enemies to deal with.
Less than 100 kilometers from Lingyan Base lies a vast rocky forest, where an S Grade alien beast Dungeon Space exists.
It was a Dungeon Space completely controlled by alien beasts, making it very difficult for humans to enter.
The main purpose of the Lingyan Base is to reduce and control the number of alien beasts rushing out from within, especially the number of high-level alien beasts.
However, compared to other Tier 3 bases, the pressure here is relatively low.
Its primary function is still to provide food.
After arriving at Lingyan Base, Jiang Ziliu lingered in the various bookstores and public libraries, constantly collecting and reading books about beast taming that he had never encountered before, as well as some other miscellaneous books.
He planned to stay here for a month to get a feel for the surrounding area and the higher-level bases before deciding on his next move.
