I became a god by treasure hunting after arriving 500 years early Chapter 1251 - 706: Triumphant Return to the Hometown (Part

And the Floating Engraving began to flicker, the spaceship carving wave-like traces in the air, its speed continually increasing.

After twelve hours, the Green Grass Knight arrived at the location of the space tunnel.

Above thirty thousand ters in the sky is a massive sky fortress nad "Sky Shield," like a colossal floating steel city.

Big, really big!

Conservatively estimated at 3,000 square kiloters!

The outermost layer of the fortress is a rotating defensive ring, densely packed with an array of turrets, resembling an impregnable tal Great Wall.

Inside the ring is a "singular light cluster" similar to a wormhole, which is the entrance to the space tunnel.

The edge of this entrance is not a smooth circle, but twisted and undulating, like a vortex stirred by an invisible hand. The opening glows with a dim blue and purple light, occasionally bursting with golden energy arcs, like lightning briefly flickering in the void before quickly vanishing.

Establishing a stable entry and exit point at the space tunnel is not easy.

"Is this fortress considered the highest combat power of the Buzhou Alliance?" Lu Yuan asked.

"Yes, it is considered the most basic Level 5 civilization structure," an expert proudly introduced, "The construction cost is 1,200 Civilization Points of materials, and eight hundred thousand Spirit Essence..."

Lu Yuan couldn’t help but be amazed, only the Buzhou Alliance could afford such an expensive thing.

If only humans... it might take another one or two thousand years of developnt—well, that’s the normal developnt tiline.

On one side of the "Sky Shield," various ships are lining up.

On the other side, various ships erge from the space tunnel.

They are transmitted from afar, either carrying cargo or personnel, heading to different parts of the Ruins of Buzhou.

So ships are still entering.

The "Green Grass Knight" spent about an hour in line, finally approaching the "Sky Shield" sky fortress, following the indicator lights all the way forward.

Lu Yuan saw an entrance resembling water wave ripples.

"After entering the space tunnel, the intelligent life on the entire spaceship cannot feel the passage of ti, as if it reaches its destination in a blink of an eye," the professor introduced again.

"But for observers outside, even traversing through the space tunnel still takes so ti. Our current estimate is that such traversal can reach about 0.5 tis the speed of light, theoretically capable of surpassing the speed of light, just like a wormhole, but this tunnel’s quality is not up to standard, with a maximum of only 0.5 tis the speed of light."

"Unable to feel the passage of ti, isn’t it due to the Theory of Relativity effects?" Lu Yuan casually asked.

"Of course not, 0.5c is not enough to cause significant ti dilation effects. It is due to so inherent attribute of the space tunnel."

"We’re going in, see you in a mont."

The spaceship entered the "water wave ripple," and in that instant, heaven and earth seed to turn pure white.

Everyone fell into a motionless state, and in higher-dinsional space, ti beca vague.

Three-dinsional matter cannot even move in higher-dinsional space.

Only Lu Yuan strolled leisurely in this pure white space.

He possesses the eye of the "Monster’s Myth," which is a top-tier space ability. Even if his body’s material is frozen, his soul can still think.

"I see, it’s not that space-ti doesn’t exist anymore, but in higher-dinsional space, speed, distance, and other physical paraters are all different from three-dinsional space."

To give a simple example, the physical parater "distance" in two-dinsional space only requires (x, y) coordinates to determine, whereas in three-dinsional space, it requires (x, y, z) coordinates.

In today’s higher-dinsional space, more paraters are needed.

And the three-dinsional matter isn’t compatible with the physics here, so it seems to be frozen.

Lu Yuan studied it for a while, realizing he was just chasing shadows, so he stopped delving deeper.

"The technology of a Level 5 civilization requires a large group of people to accomplish. For alone to want to see it all is utterly unrealistic."

However, he realized that the space tunnel is actually quite fragile, like forcibly digging a thin, tiny tunnel in a heap of sand, which would collapse as soon as the sand flows slightly.

With the ability of "Monster’s Myth," he could easily overturn it... of course, he wouldn’t do that.

"It’s not like they wouldn’t think of finding a way to reinforce the tunnel. Alas, without understanding the principle, forcefully developing cross-era technology indeed leads to the current embarrassnt."

But space’s fluidity is naturally not too high, Lu Yuan estimates that as long as it is tily maintained, it can last for a long ti.

He suddenly had a flash of inspiration: "Wait, I see! No wonder Emperor wants to create an ’Immortal Palace,’ even though space tunnel can also transmit. The more important use of the ’Immortal Palace’ is to maintain the stability of the tunnel and reduce maintenance costs."

Don’t underestimate the worth of the words "reducing costs."

Whether it’s a Sixth-level Civilization or a Level 7 Civilization, any ruler has to worry about funding issues.

The collapse of a dynasty only has one reason—no money in the National Treasury.

"If I were to dig a space tunnel myself and transport Yunhai City to the Northern Territory, how should I do it?"

Lu Yuan observed for a while and quickly grasped the thod. The tentacles of "Monster’s Myth" actually have excavation capabilities, so when the ti cos, he could use a tentacle from the Greedy Demon God to start digging.

"A tunnel that could collapse at any mont is still quite cost-effective. Sothing like what the Buzhou Alliance has at the middle level is a bit expensive... there’s no need for to dig a high-grade one myself, let’s just keep it simple."
