"The second is an advanced version of this foundation."

The Taishan Knight paused for a moment.

"Using the Time Mover, one can go back to the past."

Even though Zhou Yi had vaguely suspected this, hearing it from D's speaker still shook him.

"However, the current capability is only up to 60 seconds."

D continued: "Using the Time Mover can return you to 60 seconds earlier, which is the current limit. It's not the limit of the technology itself, but rather due to objective constraints."

"Wait a moment."

"I have an important question to ask first."

Zhou Yi interrupted: "Returning to 60 seconds earlier, does that mean you go back to the previous space, or the previous timeline?"

"Back to the space 60 seconds earlier."

D said: "It's a partial change of your temporal position, moving yourself to 60 seconds earlier. To completely return to the previous timeline, one would need to descend from four-dimensional space to three-dimensional, which is impossible in our current space."

Even so, it was still amazing.

According to its description, as long as you're equipped with the Time Mover, you can perform this 60-second return on yourself.

Similar to the temporal rupture of the Time Assassin Ike in LOL.

D stated frankly: "This technology also carries risks."

"Using it even once will cause the body to be heavily compressed and damaged by space, with a high damage rate. Without reaching the Light Core Body, perhaps only Mechanical Life can endure it, because we have spare parts, and do not fear pain or death."

"The greatest challenge is the time limitation, as time will gradually decay. The first use is the most effective, reaching 60 seconds, but subsequent uses will reduce the moving time to about 40 seconds."

"Does it wear itself out?" Zhou Yi immediately realized.

"Yes, and the depletion is significant. After approximately three uses, it becomes ineffective, and the Time Mover will be on the verge of collapse."

D said: "I conducted several tests and found the results to be consistent, confirming this hypothesis."

"You found a few Time Movers?"

Zhou Yi was extremely surprised: "Are such things so easy to find?"

"They're located in the mantle, hard to find by normal means, and incredibly strong. I only found this set, and it's highly likely that they were dropped or carried away by the Giant Bone Fish when leaving the mantle."

D explained: "To make a Time Mover reusable, you must bring it back to the Four-dimensional Space Hole, where it can be repaired over time and used again, like a fish swimming back to its usual water environment to regain its vitality."

"Through this method, I repeatedly used and explored, which is how I accumulated this experience."

Zhou Yi thought to himself, 'Damn.'

It's like exploiting a bug in space and time.

How had he not thought of this?

"However, the 60-second limit always exists, and this cycle cannot be broken."

D sighed: "The only way is to increase the number of time units, that is, to connect more Time Movers together to extend the period; this is the solution I can think of. So I want to ask you to help excavate underground and develop more Time Movers."

"Underground excavation and development require significant funding, calculated in tens of millions of Light Seeds. In this world, only you, Mr. Zhou, are willing to do this and have such financial strength."

Zhou Yi realized the point.

"If you're willing to invest in this, I am willing to share the Time Mover for your use."

Zhou Yi extended his hand: "Deal."

The other party rejoiced and shook his hand.

"Excellent, excellent! With your support, the Time Mover has even greater potential for advancement."

Immediately.

D spoke in a tone different from his previous solemnity: "Since you are willing to invest, I will share the greatest secret I've discovered with you."

"To interact with time creatures and use them to move time, the normal method won't work."

"The key is music."

Zhou Yi doubted his ears: "Music?"

"Yes. They enjoy music!"

D said mysteriously: "This is my exclusive discovery, and it's through music that I can drive the Time Mover; otherwise, it would be impossible to propel and integrate them..."
