As long as the size of a spaceship reaches the size of a capital battleship, it will basically have its own ecoregion. Generally speaking, warships of more than 300 kilometers are called capital warships, and the maximum diameter of such warships can reach 120 kilometers. Such a large space would definitely allow for a central ecoregion at the core.

This is a small artificial world, the sunlight in the sky is charged by the space folding engine, and the speed of 24-hour day and night rotation is realistically simulated. Although many people do not know what is the most suitable for human life, the speed of day and night is 24 hours, and perhaps only impermanence and some people who strictly guard the secrets of antiquity can answer.

Sunlight and air also need water, and the huge freshwater tank inside the spaceship stores recycled fresh water, part of which will go into the underground of the ecological zone, and under the control of the man-made dark river, it will become a spring and seep out of the earth, merge into a small stream and flow into the river, and then form a huge artificial lake in a low-lying place.

With surface water, there will be water vapour, and with sufficient altitude and temperature differences, water vapour will naturally condense into clouds at the top of the ecoregion. Well, now that there are clouds, as long as humans exert a little wind energy and adjust the temperature, there will naturally be a natural landscape of wind, frost, rain and snow.

Building a successful eco-district is never easy. There are too many disciplines involved, and some people have calculated that the amount of funds required for the construction of the ecological zone of the main battleship is fully increased by two percent than the amount of funds required for the main guns of the battleship.

It stands to reason that every inch of space in battle-oriented warships is extremely precious, and the production of battleships is also gold-swallowing monsters, so why do humans always spend space and money to add this bionic space to the spaceship?

In fact, this is a tradition in human history. In the eyes of many scholars, human beings have traveled into the universe for ultra-long-distance voyages, of course, thanks to the invention of the space folding engine, but the development of the other two technologies is also indispensable.

One is artificial gravity, and the other is the maturity of eco-regional technology. During the long space voyage, if human beings are in weightless conditions for a long time, not only will various physical diseases occur, but also emotional breakdowns are very easy. In the earliest days of spaceflight, there was a tragedy where a madman destroyed an entire spaceship.

With the maturity of artificial gravity technology, and then the ecological zone technology also came into being, human beings in navigation finally do not have to face steel walls and endless instrument parts every day, when blue sky and clear water, grassland hills, stream towns appear in front of people, when barbecue and beer are passed at banquets, human beings finally begin to regard the icy spaceship as their home.

Until now, warships with eco-zones have been the great love of those soldiers, and they can get a vacation without anchoring on any planet, which makes them feel not mentally tired even if they cross the entire universe.

Moreover, there is another layer of truth in the construction of ecological zones that is difficult to explain. Human society is a hierarchical society, and even a country that flaunts freedom like the Ninth Republic actually has classes inside. The big man takes a spaceship, and who wouldn't want to live under the blue sky and white clouds and spend a long journey in a quaint villa?

Therefore, when Styx discovered the location of the ecozone, he did not hesitate at all and directly commanded Impermanence to rush towards the ecozone, as long as he captured a few high-level captives, this gamble was completed.

"Rushing to the ......" impermanence like an ancient siege tank crashed out of the crowd, and behind him, the River Styx sang a war song that no one could hear clearly, so that impermanence's speed, strength, and flexibility were greatly improved, and he also picked up a few fish that slipped through the net.

The brawlers present were all dumbfounded, in just a quarter of an hour, more than 150 brawlers had been overturned by impermanence, although there were no deaths, but there were many comatose and broken bones.

It is only now that these usually arrogant warriors believe in all the legends of impermanence, this guy is really a difficult black dragon, and he really deserves the name of impermanence.

"Support, emergency support...... We can't stand it, the gate of the ecological zone is about to be breached......" Before he finished speaking, the impermanence of the figure suddenly disappeared, and the steel ram that he had transformed into a construction vehicle slammed directly into the alloy airtight door at the fastest speed.

Hearing a bang, the entire airtight door flew inward for more than 200 meters, and the dazzling sunlight shone directly into the impermanence of the eyes. "Damn, it's a luxurious ecological area......" When Impermanence adapted to the light, he found that there was actually a waterfall more than 300 meters high.

The ecological area inside this strange warship is actually a continuous mountain, the altitude of the mountain peak is more than 3,000 meters, and fortunately, the maximum diameter of this battleship reaches 120 kilometers, which can create such an extraordinary mountain.

Dense forests, canyons, cliffs, waterfalls, rushing rivers that cross the mountains, and villages and towns nestled among the mountains, on the highest main peak, Impermanence saw with his own eyes a huge castle built of huge stones, like the Potala Palace.

Just as Impermanence and Styx stood at the top of the stone wall in a daze, a tsunami-like roar came from behind them, and enemy reinforcements finally arrived. Impermanence looked at the black oppressive enemy, not flustered at all, he bent down and picked up a boulder that was hugging thick, "Go you ......", and threw the stone like a cannonball with both hands.

The boulder that one person hugged together must not weigh four or five tons, and it rolled and crashed into the crowd, and just when the brawlers wanted to dodge, suddenly Styx said "No...... Move...... As...... The four words "mountain ......" are four sonic magic, which actually suppressed the vitality of the enemy's reinforcements in an instant.

Those brawlers were obviously wearing the Inquisitor armor, but at that moment, they found that their bodies were filled with lead, and the armor became a burden. They watched as the boulder crashed into the crowd, and the formation that had just been lined up was in chaos.

"Hahaha, brothers are united......" Impermanence yelled, followed by Styx shouting "Qili Broken Gold...... Haha...... "The two laughed domineeringly.

"Stinky boy, don't be arrogant......" Just as Impermanence and Styx relaxed their vigilance, suddenly a black shadow rushed from the side of the stone wall, and the instantaneous speed actually caught up with Impermanence. The cannonball-like attacker stretched out his hands and slammed into the two men, and the three of them tumbled and fell off the cliff.

The attacker was a man in pitch-black armor, and the tempered glass on his helmet had been coated with radiation, making it impossible for Impermanence to see his face at all. But one thing is for sure, this guy is not only a peak martial artist, but also wants to be high in the realm, and he can knock two peak martial artists away with one blow, this kid is absolutely difficult.

Impermanence and the others entered the area, behind the door was a platform on a cliff, and in front of the platform was a cliff, a distance of one hundred and fifty meters from the opposite hillside. The moat is connected by a chain bridge, and just to the left of the rope bridge is a roaring waterfall in the distance.

Now it's good, Impermanence and Styx don't have to cross the bridge, so the sneak attacker flies directly into the mountain stream. The three of them were actually interested and screamed loudly, "Ah...... Yes...... Ah......" Listening to the echo of the voice, impermanence actually poured out three points of childlike joy in his heart.

However, the good times did not last long, the distance of 300 meters was over in a while, and when Impermanence and Styx were about to ignite the angel wings near the water, the black attacker made another move, he actually violated the laws of nature and shot left and back on the water, and kicked Impermanence and Styx into the water with a combination of fists and kicks.

In the turbulent river, the visibility is almost zero, and the huge drop gives the water endless kinetic energy, and even the huge rocks are loosened by the impact. Fighting here is pure gambling, and the three of them are fighting completely on instinct, rushing down the current as they fight.

In the middle of the tumbling white Lang, a head was exposed from time to time, and then it was dragged down by the people underwater, and then there was a fierce battle underwater. Don't look at Impermanence and Styx, but the black raiders actually fought a tie with them because of their familiarity with the terrain.

Impermanence was shocked in his heart, he didn't expect that his peak strength would join forces with the River Styx, and actually fight a draw? This is really too embarrassing, thinking of this, Impermanence can't take care of his physical and mental fatigue, and a spiritual whip rushes over. At that time, impermanence was felt, and the body of the enemy under the water trembled suddenly, and he was definitely hit.

"Ah......h But this kid is ruthless enough to give impermanence a big counterattack on the spot.

"Impermanence...... You stinky boy is too ruthless to do it......" After saying that, two violent arcs of electricity rushed into the water, almost electrifying Impermanence and Styx into roast chicken on the spot.

Impermanence and Styx also emerged from the water, and they all heard the screams ......of the attackers. This section of the river was much smoother, and Impermanence could see the attacker at a glance. When the radiation-resistant coating dissipated from the tempered glass visor, Impermanence cried out.

"Damn, it's your ......"

"Hahaha, how's it going? I didn't expect that...... I'll show you how powerful I am today......" The guy in the black armor who was good at discharging electricity underwater suddenly blew a sharp whistle from his mouth.

"My brothers, come out and let the ghosts see our military might......" A loud roar was exchanged for a response from all over the mountains, one after another angel wings rose from the ground, and thousands of armored brawlers flew in the sky, one by one like a military parade through the mountains, lined up in a variety of neat queues.

"Inquisitors? are all Inquisitors...... Oh my God, I saw an army of Inquisitor armor...... "The well-informed Styx was shocked.

"One, two, three...... Eight nine ten...... There were actually ten thousand people flying by, and there were actually 10,000 fighters dressed in judges here...... "Impermanence is drooling, yes, you are not mistaken, impermanence is drooling" Damn, when would Lao Tzu also have such an army of fighters......"
