This battle also allowed the Tang army to discover the weakness of these giant birds.

Don't look at their pair of sharp claws, they can shatter gold and stone, but because of their huge size, their bodies are heavy.

Once they hit the ground, it is difficult for them to take off immediately, and they can only staggering and running to accelerate, and they can only fly when they encounter an oncoming wind.

That's why they choose to place their nests on cliffs.

As long as you jump down and fall like a weighing stone for a while, you can fly.

Through observation, the Giant Gang bird feeds mainly on sea creatures that have been killed by the waves on the cliffs.

However, the mist from the waves on the reef is also extremely dangerous for them, because their bodies are too heavy to fly far, and once their feathers are touched by water, they cannot fly.

Fortunately, this ferocious giant bird was detained in Zhongyunzhou, otherwise Nanyunzhou, which is only more than a thousand kilometers away from Zhongyunzhou, would be unlucky.

The predicament encountered by the Tang fleet aroused the interest of the Tang army more and more.

Although the resources of Nanyunzhou are abundant, the terrain is too gentle, and there is almost no place around the island that can be used as a barrier, and once an enemy comes to attack, you can land on the island anywhere.

This is also the main reason why a group of dace people who can land, but can't stay out of the water for too long, can force the people of the Three Kingdoms of Nanyun to live away from the coast.

If the Tang Army of the Trek Atlas wants to survive in this world, it is impossible to expect all the native races to be as gentle and polite as the villains of the Three Kingdoms of Nanyun, so it is necessary to find a base camp that is safe enough.

And the easy-to-defend and difficult-to-attack terrain of Zhongyunzhou is really suitable for use as a permanent base, and those giant birds also make Tang Jun very thoughtful...... It's so big, it should be able to carry people, right?

If it can be domesticated into a mount, but even the "carrier-based aircraft" will be equipped, and then the Datang fleet will be able to advance, attack, retreat and defend, and it can also realize relay long-range strike tactics, so they have to find a way to land against these giant birds.

A large number of ships were dispatched to carefully explore around Zhongyun Continent.

The area of Zhongyunzhou is about three times larger than that of Nanyunzhou, roughly estimated to be about 25 million square kilometers, and the terrain is roughly oval.

To be honest, this area should not be called an "island", but compared to the scale of the Xiyan Sea and the Great Wilderness, it seems that it is not wrong to say that it is an island.

Topographically, Zhongyunzhou is steep in the north and gentle in the south, the cliffs in the north are high and uplifted, and the south is relatively low, which is similar to the topography of the north mountain and the southern plains of Nanyunzhou, which should be caused by the same geological activity.

There are a large number of rugged reefs around the base of the island, but they are generally submerged by the sea, which is why Zhongyunzhou looks like it is alone in the ocean.

People always come up with solutions.

After perceiving the dense reef groups around Zhongyun Island.

The Tang army immediately sent a ship back to Nanyunzhou and took all the craftsmen of [Tiangongmen].

Using the unscientific civil engineering spells they mastered, they pulled up the reef hidden below the sea surface and formed a breakwater to slow down the undulation of the waves, and artificially built a wave-proof waterway for ships to approach in the relatively low south coast of Zhongyunzhou.

At the same time, the cliffs on the south bank were excavated to create a gentle slope for landing.

The excavated rocks were thrown into the sea to build docks and berths for the Tang fleet to dock.

This is an incomparably huge project, and when the craftsmen of [Tiangongmen] are constructing, it is naturally impossible for the Datang fleet to be idle.

In addition to leaving a part of the soldiers behind to protect the craftsmen from the giant birds, they continued to sail north until they reached Beiyunzhou, where the Zhangren Kingdom was located.

Compared with the Three Kingdoms of Nanyun, the three clans of the Zhangren Kingdom in Beiyun Continent are obviously more primitive, and they are still in the primitive tribal stage of slash-and-burn farming.

At the same time, because the climate is even colder, the resource production here is far from being compared with Nanyun Zhou, and the elders of the three clans have to work hard for survival and food.

So after using the majestic steel giant ship to deter the Changren clan of Beiyun Continent.

and the Changgu people who wandered to Nanyunzhou to settle came forward, and easily hired a large number of elders of the three clans to work in Zhongyunzhou with grain.

The three patriarchs have long legs and long hands, and they don't need to build ladders for high-altitude work.

The strength is even greater than that of the villains of the Three Kingdoms of Nanyun, I don't know how many times, and it can be regarded as solving the problem of insufficient labor in the Tang Army.

The area of Beiyunzhou is more than ten times larger than that of Nanyunzhou, and the area is at least more than 70 or 80 million square kilometers.

It's just that the three patriarchs live in small tribes, and there is no complete political system to manage, so it is difficult to count how many people there are for a while, but the mineral reserves on Beiyun Island are very large, and they can be developed as a mining base for future development.

At a time when the Datang fleet was constantly transporting labor from Beiyunzhou to Zhongyunzhou.

After the initial excavation of the landing site, the Tang army team, which began to explore on Zhongyun Continent, also discovered a group of strange humanoid races in the interior of Zhongyun Continent.

This group looks very human, at least in appearance and size.

But it is obviously in the stage of uncivilized primitive people, both men and women, young and old, are red fruits, and they don't even know how to wrap a piece of animal skin around their bodies to cover their shame.

When the Tang Army scout team found them, these primitives were being attacked by a giant bird.

Obviously, the number of the tribe is very large, but under the hovering and fluttering of the giant birds, they will only scatter and flee like a panicked rabbit swarm.

Until the giant bird pecked them to death, one of their people began to eat on the spot.

These primitive people immediately regained their composure and continued to rummage through the grass for seeds and insects to fill their stomachs.

But they turned a blind eye to the bloody images that were close at hand, as if they knew that the giant birds would leave when they were full and would not attack them again.

The Tang Army's scout team couldn't stand it and rushed forward, slashing the giant bird that didn't have time to take off, but instead scared those primitive people so much that they screamed miserably and scattered.

When the scout team killed the giant bird, they turned around, and suddenly looked confused.

What about so many slick people all over the mountains just now? Why are they all gone?

You must know that the topography of Zhongyunzhou is a bit like an antenna pot with a convex exterior and a concave inside, and the vegetation is basically grassland except for the sparse low shrubs.

The surrounding environment is unobstructed as far as the eye can see, so no matter how fast these primitive people run, they cannot disappear without a trace in an instant.
