When Chen Jingyuan first entered here, he was completely stunned by every item and furnishing here.

He knew very well that this was definitely not something that belonged to their civilization.

Moreover, this battleship has been spotted for a hundred or two hundred years.

None of humanity's technology has reached this level today, let alone more than a hundred years ago.

And this battleship should have existed underground for a very long time.

There are very few things that can be collected.

Most of them have rotted.

The only thing he was curious about now was what was in the area inside.

He knew that he would never be able to open that door with his own abilities.

That's why I agreed to Lan Xi's request and brought her over.

He had no children.

Instead of letting everything be sealed in history, it is better to let Lanxi uncover the truth.

"Master, after analysis, this battleship should belong to the G series, which is a relatively old model. Judging from the internal situation, it should be no less than 5,000 years since the crash was carried out here. Mobao said.

"Is the control center still intact?" Blue Creek asked.

"It's damaged, and it can be repaired, but there's no material here." Mobao said.

At this time, Chen Jingyuan suddenly stopped.

"Master, this is it." Chen Jingyuan stood in front of a metal door more than three meters wide.

The metal door was covered in rust and dust.

But you can still see some mysterious lines distributed on it.

"It's a kind of formation." Blue Creek swept away the dust from the metal door.

"Formation? Can that be broken? Chen Jingyuan didn't know anything about this, so he could only put his hope on Lanxi.

"This formation is very complicated, but because the energy has been basically exhausted, it can be forcibly broken with external force." Lan Xi took a step back, turned his hand and took out the Meteor Iron Dagger, injected spiritual power, and stabbed into the center of the formation.

I only heard a cracking sound of "click", and cracks directly appeared on the formation.

Immediately afterward, the metal door automatically opened to both sides, revealing a long passageway.

Lan Xi and Chen Jingyuan stepped in.

At the end of the passage, two paths appeared.

"Master, which way are you going?" Chen Jingyuan asked.

"Right side!" Blue Creek chose a random direction.

……

Outside the battleship, Tang Yuan and the others used their spiritual power to force out the toxins in their bodies, and they all regained some strength in their bodies.

"Luo Ran, you come and open the door." Tang Yuan twisted his neck and said.

"Yes, Captain." Luo Ran stepped forward and took a closer look at the metal door.

Because they smashed it badly just now, there are still many traces of violent destruction on the metal door.

So it took a few minutes for Luo Ran to determine the location that Chen Jingyuan had touched.

"This should be it." Luo Ran pointed to a triangular symbol on the relief of the metal door.

"Can't see any gaps or protruding spots?" Someone stepped forward.

"Just try it and you'll find out!" Luo Ran reached out and pressed the triangle symbol.

However, there was no reaction.

The triangle symbol doesn't look like it can be pressed either.

"Could it be that there is a problem with the duration? I saw the old man stand here for a few seconds before the door opened! Tang Yuan guessed.

Hearing this, Luo Ran's eyes lit up, and he put his finger on the triangle symbol again.

Five seconds later, the metal door suddenly shuddered and then slowly rose upward.

"It's open!" A smile appeared at the corner of Luo Ran's mouth.

But when they saw the layout inside the metal door, they couldn't help but have a look of shock on their faces.
