It paused for a moment, then continued, "But I can't leave here yet. Everyone here needs to be liberated, not just me. I have an idea. Do you want to hear it?"

Li Wenjia came forward and pulled Lin Ke up. It was really heavy, probably several hundred kilograms. He replied, "Let's talk while we walk!"

"We lack energy here, just like you. But we have lost our enterprising spirit, which is very different from you. I have seen the day when you solve the problem, so I really want to go to your place." Lin Ke opened a door and they walked into an elevator.

"But if I leave, what will happen to them? What will happen to the others here? Who will they rely on, and who will I rely on? The book clearly states that if he could rely on them to accomplish that great cause, then I think I should be able to do the same."

"I respect your decision," Li Wenjia replied, pushing open another door. "But I hope you understand that no one can accomplish something big alone. We need unity, even if it's just a deal where we each get what we need."

"Transaction?" Lin Ke blinked. "Do you mean 'my history'?"

"No, it's a gift." Li Wenjia explained immediately.

"Really? Since it's a gift, what's your return gift?"

"What kind of return gift do you want? I don't have much to offer." Li Wenjia curled his lips.

"Nothing much, I just want 'follow-up' and 'reference'. The records in your data disk are already quite damaged."

It took Li Wenjia a while to figure out what it said and what it meant.

He pushed open the last door and they came to a hall.

This was a train service center, and standing by the bar were many robots that looked like Lin Ke. Their postures varied, but within their expressions, they all possessed a mysterious soul.

They are different, and at the same time, they are exactly the same.

"Are they all your friends?" Li Wenjia asked.

"No, they are all me." Lin Ke and the others said in unison, "They are all part of me."

The mechanical hound appeared again, this time holding a cloth bag. It quickly shuttled between Lin Ke, then circled Li Wenjia twice and squatted down facing him.

Inside the cloth bag was a paper box, and inside the box was a data block that was several times larger. The interface of the data block was still similar to the original one.

"What is this?"

"My history, or perhaps you could say, is my clone, my seed."

"How am I supposed to bring you the return gift? The strike zone is full of hunters now!"

"It's called Lorenz. I raised it as a pet using a subroutine. You can take it with you. There are many hunters here. They are products of the automatic factories I control. I know them very well. It's not too much to ask, right?"

"In that case, farewell, my comrade!"

Li Wenjia looked back every few steps and left with Lin Ke's best wishes.
