I know this ancient god

Just a tenth of a second before the aircraft was about to hit the wall, the wall swung like a curtain blown by the wind, revealing a gap just enough for the aircraft to pass through.

The aircraft flew into the wall, and the surrounding walls kept swinging, leaving a gap for it to move forward. From God's perspective, it is like a fish swimming in water, displacing water wherever it swims.

Tang Xuan was once again amazed by the technological level of Neutron Battle Star. He asked: "How many years did it take you to develop to this level?"

The robot answered frankly: "It has been a million years since I mastered steam power. During this period, I have experienced many wars and gained many opportunities."

One million years after steam power.

Tang Xuan thought for a while and realized that mankind has only now gone less than 1% of the way. If it wants to reach the level of Hill civilization, the Federation still has 990,000 years to go.

He sighed: "It took so long."

The robot suddenly asked: "How long? As far as I know, the shortest lifespan of a star is a few million years, and the longest lifespan is one trillion years. In comparison, one million years is not that long."

Tang Xuan shook his head: "Human civilization is composed of countless individuals. The time scale of one million years is enough for all individuals to change ten thousand times. Human civilization one million years from now will no longer be the original civilization."

The robot fell silent after hearing this.

Tang Xuan didn't say anything and turned around to continue observing the surroundings.

The closer he got to the depths, the more man-made objects there were. Sometimes the aircraft would plunge directly into a large cavity, allowing him to see many mysterious instruments that he had never seen before.

After a while, the robot suddenly said: "I'm sorry, I always involuntarily ignore this fact and look at human beings as a whole."

Tang Xuan said nonchalantly: "You are not wrong. As an intelligent life, you are immortal. It is normal to think about problems on a larger scale."

The robot said quietly: "But I made a big mistake because of this."

Tang Xuan's heart trembled.

Big mistake means

At this time, they passed a robot maintenance center and the aircraft stopped.

The robot jumped down: "Wait a moment!"

It walked to a groove and lay down in it, and a robot that looked exactly like it stood in another groove next to it, except that this robot was very neat and tidy without a trace of dirt.

The intelligent mastermind changed his body.

Tang Xuan looked at the assembly line next to him and found that the old robot had been transported up. The old robot first passed through a water curtain with a lot of foam, and then was transported elsewhere by conveyor tracks for other maintenance work.

The new robot got into the aircraft: "Where did we just talk?"

Tang Xuan replied in a deep voice: "You said you made a big mistake."

The new robot's rotating arm made a clicking sound: "Yes, I made a big mistake."

Tang Xuan held his breath and concentrated.

He wanted to know whether the Hill civilization perished because of this mistake of the intelligent mastermind.

"I discovered Hill Civilization. I thought Hill Civilization had only one subject consciousness like me, so I stepped forward and said hello to them." The little robot's voice became extremely low, "They also said hello to me. I thought we could be friends, but I was wrong."

"What's the meaning?"

This intelligent life was not created by the Hill civilization?

Tang Xuan's eyes became solemn.

He heard a possibility that had not been considered before.

This time the little robot did not answer him smoothly, but remained silent for a few seconds, and finally said in a stiff voice: "We will be there soon, let's talk later."

It's like he's a different person.

The truth was about to be revealed. While waiting, Tang Xuan felt as if a kitten was scratching his heart, making him itchy.

What is the relationship between this intelligent life and Hill civilization?

How did it enter the neutron battle star of Hill Civilization?

How much does the demise of Hill civilization have to do with it?

What's going on with those battleships outside?

What happened that year?

Many questions were lingering in his mind.

Finally, they entered a spacious hall with many tables and chairs fixed to the ground and huge screens on four sides.

The little robot pointed to an iron door located in the corner of the hall.

"I'll wait for you there."

After saying this, the indicator light on the little robot flashed several times, spoke a sentence in Hill language that Tang Xuan could not understand, and then jumped off the aircraft and walked in the opposite direction to the door.

The intelligent mastermind left the little robot, and driven by the program, the little robot began to work.

Tang Xuan sat alone on the aircraft.

He didn't understand why the intelligent master had to wait for him at that door. Was there any difference inside and outside the door?

He wasn't worried about the trap behind the door.

The Hill Civilization that built the Neutron Battle Star has no reason to set up dangerous traps in the core area of ​​the Neutron Battle Star. After all, if an enemy really hits here, one or two traps will not help.

Tang Xuan stepped off the aircraft.

He was full of curiosity about Hill's civilization. He did not push open the door in a hurry, but walked to a table first.

There was nothing on the table, but there was a photo embedded in the transparent interlayer on the surface of the table. The photo showed a man and a woman wearing pure white clothes standing on the lawn holding a child.

The man's face was majestic, the woman looked happy, and the child smiled innocently.

The former owner of this table must have been one of the three people in this photo. I wonder if he would miss the other people in the photo before his death.

Tang Xuan casually opened a drawer and unexpectedly found that there were many documents inside. He reached out to pick them up in surprise. But the moment his fingertips touched it, all the documents turned into brown powder.

There is some kind of power in the drawer that allows things to survive the erosion of time, but when the drawer is opened, this power is lost.

Tang Xuan silently closed this drawer and stopped trying to open other drawers.

He walked toward the door in the corner, but instead of walking in a straight line, he walked through the tables.

There is a transparent mezzanine on the surface of each table. There is often a photo or a note in the mezzanine. This is the care of the table owners to encourage themselves to persevere in this dark place.

However, there are also tables with a form on them.

Although Tang Xuan couldn't understand Hill Civilization's text, he could tell that it was a timetable, roughly allocating the table owner's time for the day.

He stayed at the table with great interest for a while, looking at the table and guessing the schedule of the table owner.

Finally, he came to the door.

There was no handle on the door, so he pushed it tentatively, and with a soft click, the door opened. A golden light shot out from inside and circled around his head.

"You finally came to save me!"

Jin Jiaojian circled around Tang Xuan excitedly.

"What did you do to my hair?"

Tang Xuan looked at his fallen hair in confusion.

I'm here to save you

Is this how you repay me?
