High Martial Arts: Slay enemies to become stronger, forge invincibility from billions of corpses.

An hour later, Song Chen arrived at the 374th spatial node defense line, which was 2.2 light-years away from the main defense line of Tian Shu.

He looked at the Tian Shu defense line from here. This huge defense line, spanning seven light-years, was suspended on the outer edge of the Black Dimension Nebula, locking the entire nebula, along with its ionized dust, newborn stars, and asteroid belt, within a visible energy grid.

Countless fortresses, fleets, and cruiser warships moved slowly within the band of light, like blood flowing in an infinitely long vein.

The light surged from the direction of the main defense line, and after traveling a distance of 2.2 light-years, it had weakened to only a faint silver-blue.

Song Chen stared in that direction for a long time.

2.2 light-years is a distance that is almost negligible on a cosmic scale.

If the space blockade had been activated before, Shadowbee would have only needed one jump, and in about twenty seconds, before he could even adjust his posture on the back of his chair, he would already be standing next to the main defensive line.

If he wanted, he could even skip the Shadow Bee and use Void Travel to jump across the weak points in space, one by one.

Although it takes time and effort, it's still a path.

But things are different now.

The spatial blockade of Tian Shu had already covered this area. He could feel it; it was a force that was always present, as if the entire starry sky was being immersed in an invisible, thick liquid.

The space is no longer light and airy; it has become heavy and stagnant.

In this environment, a regular warp drive can't even locate itself; all the spatial gaps are sealed off, and all the paths that could have been torn apart have disappeared.

The only exception is the military jump window that the Joint Defense Council specifically opened and encrypted.

If space hadn't been blocked, 2.2 light-years wouldn't have been much.

From one node to the main defense line, it only takes the blink of an eye.

However, in the context of this sealed-off starry sky, 2.2 light-years is an insurmountable chasm.

If the enemy comes from the outside and wants to bite through the main defensive line of Tian Shu, they must first cross this distance.

Even traveling at the speed of light would take more than two years, and even if the Blood Erosion Civilization's biological warships could maintain sub-light speed for a long time, they would only be crawling through space.

Two years is enough time for the main defense line of Tian Shu to mobilize support dozens of times.

This is the true significance of the Tian Shu defense line.

Song Chen has figured out a lot: Tian Shu is a sea.

The spatial blockade turned the universe, which could have been traversed in a single step, into a perilous wasteland that had to be filled little by little with physical bodies, ships, and time.

The defending side has the privilege of warp jumps, which allows them to instantly mobilize troops, deploy resources, and provide support.

The enemy, on the other hand, had no choice but to fly slowly and take it one step at a time.

The initiative was in Tian Shu's hands from the very beginning.

Song Chen shook his head, clearing his mind of the thoughts, and then turned to look at the location where he was about to serve, node 374.

It was a fortress city suspended in the void.

The city appears as an irregular hexagon from a distance, with a diameter of about 300 kilometers, and its base is surrounded by a thick armored skirt.

The upper layer was completely covered by a light blue energy shield, and small ripples appeared on the surface of the shield from time to time, which were traces of the interaction between the spatial blockade and the shield.

Dozens of towering psionic turrets are scattered on the city's outskirts, their barrels pointing diagonally in all directions.

And the golden light at the very center of the city is the living spatial node.

A massive pillar of light, over five kilometers in diameter, shot into the sky from the city's core, its upper end piercing the void and its lower end deeply embedded in the foundation of the fortress.

Countless fine runes flow within, each rune resembling a half-open eye, ceaselessly releasing spatial suppression fluctuations outward.

The fluctuations were extremely subtle, and on the surface they only slowed down the flow of psionic energy in the surrounding area. In reality, however, they, along with tens of thousands of similar nodes, formed an invisible giant network covering seven light-years.

Song Chen understood the weight of this thing at just one glance.

The port guidance system automatically took over the ship, leading him into a deep, dark metal docking tunnel.

The hatch opened, and Song Chen stepped out.

Several people were already waiting outside.

The leader was an officer, tall and thin, with gray hair and skin that had a very faint blue tint.

The officer nodded to Song Chen and said, "Song Chen?"

"it's me."

"I am Virian, adjutant of the 3rd Battalion of the Node Guard. The garrison commander sent me to pick you up."

Song Chen nodded, and Virian turned to lead the way.

Song Chen followed behind him, walking through the port corridor.

The passageway is flanked by thick metal walls covered with energy pipes and space stabilization devices, with a small teleportation array every few steps.

The lights shone down from above, casting long shadows of the two people.

People came and went in the passageway; some carried ammunition boxes, while others leaned against the wall and closed their eyes to rest.

Song Chen looked around and said, "There are quite a few troops stationed here."

Without turning his head, Virian replied, "It's not a lot, but it's definitely a mixed bag."

"Moonshadow, Frostmoon, Radiant Sun, Rock Iron... Dozens of civilizations have sent people here, totaling hundreds of thousands, crammed into this one place."

"They cause trouble all the time, and even their fights require three separate detention areas. Fortunately, the garrison in Guanzhen can hold them off."

"Who is the garrison officer?"

"Zefal Kron, an eighth-order Star Crown Realm cultivator, is also a member of the Alliance. He was originally the deputy commander of the Eighth Garrison of the Third Legion in the Milky Way."

"He's also the highest-ranking commander at this node. You'll find out when you meet him later."

There was a clear sense of awe in Virian's tone.

Song Chen didn't say anything more.

The two walked through the port area and entered the city's central axis.

As Song Chen walked around, he observed that the city appeared to be a purely military fortress from the outside, but once inside, it had developed into a small metropolis.

The streets were paved with alloy plates, and on both sides were metal buildings of varying heights, some used as barracks, some piled with supplies, and some marked with signs for medical stations.

There aren't many shops, but there's a currency exchange point every few blocks, with queues forming outside.

Soldiers from different civilizations lived together, each with their own circles.

The Moonshadow Clan members are mostly clad in silver armor and wield long swords, speaking while nestled in the shadows of buildings.

The people of the Huiyang civilization have golden patterns on their skin, and they exude warmth as soon as they appear, as if they have a small sun hidden inside them.

The heavily armored warriors of the Rock Iron Civilization are the most conspicuous, their bodies made of rock and metal, and the ground trembles with every step they take.

There were also some races that Song Chen couldn't recognize. Some had two pairs of eyes, some had psionic tentacles extending from their backs, and some were simply a cloud of gray mist bound inside armor.

This is what cosmic warfare looks like: people from different civilizations, races, and languages ​​are crammed into the same fortress to do the same thing for the same war.

The gunfire between nations on Earth, placed here, is like two groups of ants fighting over half a loaf of bread in an anthill.
