Everyone's playing Red Giant? I, Black Hole, devour everything!

Upon seeing this, Lin Tian was overjoyed.

He was still marveling at how advanced the Ayrs' use of gravity was when the design drawings appeared before him.

The drawings are very clear, but the amount of content is enormous; it would take at least a year and a half to finish reading them.

But after a quick scan, Lin Tian immediately realized how precious it was.

From material selection to geometry optimization, from frequency tuning to phase coupling between conductors... every detail is clearly marked.

If they can thoroughly understand these blueprints, the Great Xia Kingdom could even begin to attempt to build its own gravity array!

Moreover, introducing a small gravitational array into the observation chamber can significantly improve the accuracy of the observer's control over the gravitational field!

This is even more important to the Black Hole Legion.

After all, the most important thing about black holes is gravity. Improving the precision of gravitational field manipulation will make black hole merging and evolution much easier.

"If we bring this back to the research institute, Professor Zhou and the others will probably be so excited they won't be able to sleep."

Lin Tian couldn't help but chuckle to himself.

He immediately added the drawings to the observation module's local database.

"Let's look again, there's still a lot more!"

Lin Tian continued to examine other contents of the database.

After about half a day, his gaze suddenly stopped.

That's a set of coordinate data.

There aren't many, only twelve in total.

Each coordinate corresponds to a gravitational wave relay station built by the Ayers within the Milky Way galaxy.

"Coordinates of the twelve relay stations... Looks like we're in for a lot of running around now."

Lin Tian gave a wry smile.

Each relay station is like an ancient ruin; you have no idea what secrets it holds.

Therefore, Lin Tian cannot let any of these relay stations go!

However, most relay stations are located at extremely far distances, and are not even located in any of the known star regions of Earth.

After the arrival of Universe Online, although the world was divided into multiple star sectors, all star sectors are actually located in the Milky Way galaxy and only occupy a part of the Milky Way galaxy.

Beyond the known star sectors lie countless galaxies and an endless unknown universe.

It is a mysterious ocean, and also a mountain range full of treasures.

"However, there is one coordinate in a known star region..." Lin Tian immediately compared that unique coordinate with the star map.

Because the coordinates were from hundreds of millions of years ago, they needed to be recalculated, so it took Lin Tian a full three hours to complete the final calibration.

When the new coordinates appeared, Lin Tian's gaze froze.

The coordinates of this relay station happen to correspond exactly to the star sector where the mainland of Japan is located.

More precisely, it is the star sector where Tokyo, the first star sector of the Sakura Kingdom, is located.

"Tokyo……"

Lin Tian murmured the two words, a glint of something unfathomable flashing in his eyes.

He zoomed in on the coordinates and pulled up more detailed comparison data.

The data came out quickly—the landing point of this relay station was less than thirty light-years away from the mainland of Japan.

Thirty light-years is practically like being in your own backyard on a cosmic scale.

"No, it's not just about being close by."

Lin Tian suddenly realized something.

The location of this relay station is very special.

It was not placed in the core of the dark matter halo or deep within the barren region.

It is right next to a living, active star system.

This method of site selection is completely inconsistent with the usual practices of the Ayrs people.

Unless—this relay station holds something even more special.

Lin Tian continued scrolling through the database, trying to find more records about this relay station.

About half an hour later, a message marked "Top Secret" caught his attention.

[Mid-Third Era: Backup of Defense Technology Research]

Project Code Name: Gravity Shield

Gravity shield.

Upon seeing these four words, Lin Tian's pupils contracted slightly.

He immediately opened the details of the message.

Gravity Shield is a defensive technology developed by the Ayrs based on gravity array technology.

The principle behind it is actually not complicated.

Conventional defensive measures, whether armor, shields, or energy barriers, are essentially about using one substance or energy to counteract an attack from another substance or energy.

This method has an inherent flaw: you have to use just as much energy to counteract the energy the enemy attacks.

The contest between the offensive and defensive sides boils down to who has more energy reserves.

But the concept behind gravity shields is completely different.

It does not counteract the attack.

It's used to change the direction of the attack.

A space-curving layer is constructed around a star using highly compressed gravitational waves.

Any attack that approaches a celestial body will be "bent" by the curvature of spacetime itself as it passes through this curved layer, grazing the edge of the celestial body.

It's like using a gravitational lens to bend light.

This time, however, it wasn't just light that was bent, but all forms of attack.

"What a clever idea..."

Lin Tian couldn't help but sigh in admiration.

He continued reading.

The advantages of gravity shields are obvious.

It doesn't use brute force to withstand attacks, but rather uses skill to deflect them.

This is just like practicing Tai Chi.

When your opponent throws a punch, instead of meeting it head-on with your fist, you use your wrist to hook and deflect the force of the punch to the side.

The same applies to gravity shields.

It doesn't need to consume enormous amounts of energy to counteract the attack; it only needs to maintain the stability of that space curvature layer.

Therefore, its equipment cost is extremely low.

Once scaled up, the cost of equipping a star with a gravity shield could be cheaper than that of a typical observation module.

More importantly, the gravity shield is almost immune to most conventional attack methods.

The thermal radiation of stars, the gravitational field suppression of neutron stars, and the matter impact of quark stars—these common attack methods in cosmic warfare are basically ineffective against the gravitational shield.

Because their essence is to apply energy or gravity to the target in some way, and the gravity shield can deflect all of this energy and gravity.

Of course, gravity shields are not a panacea.

It has an inescapable nemesis.

Black hole.

The gravitational field of a black hole is the collapse of spacetime itself; it is not an "attack" but an "environment".

While a gravity shield can bend space, it cannot counteract the extreme spacetime drag caused by a black hole.

Once locked by the event horizon of a black hole, the gravitational shield becomes meaningless.

Because in front of the event viewpoint, even light cannot escape, let alone the curved space.

Therefore, gravitational shields are not very useful against black holes, because black holes don't need defense in the first place.

But for other celestial bodies, the value of this technology is immense.

Red giants, blue giants, pulsars, neutron stars, quark stars—these celestial bodies are almost invincible when facing opponents of the same magnitude!

"No wonder the Ayers placed this relay station next to the star system... its strategic value is too high."
