Under normal circumstances, there was only one timeline at the beginning of a basic dimension's birth. This timeline that had existed since the beginning was also known as the main timeline.

In addition to the main timeline, other timelines would also be produced in the dimension due to certain special reasons.

For example, a powerhouse could travel through time and return to the past and change the outcome of what should have happened in the past. Such changes to what had happened would have a huge impact on the continuity of time and would usually result in two outcomes.

One was that the relevant imprint on the main timeline was erased. For example, a person's parents were killed by someone who traveled to the past. In that case, the person would be completely erased from the main timeline. No one would even remember the person's existence. This was because the person's existence violated the rules of time and could only be erased by the rules of time.

The other situation was that what had already happened in the main timeline could not be changed. For example, a person's parents were killed by someone who traveled to the past. However, in the main timeline, the rules of time could not erase the person's existence due to certain special reasons. In that case, the rules of time would automatically repair the timeline and allow the person's parents to fake their deaths. The so-called fake death was when the person's parents were not actually dead in the main timeline. However, the rules of time had derived a new timeline. In this new timeline, the person's parents were dead and the person did not exist.

Therefore, the subsidiary timelines were not parallel to the main timeline. Instead, they branched off from the main timeline, like branches derived from a tree trunk. They were the product of the rules of time's self-correction and were incomplete. Most of them were unstable and could be automatically annihilated at any time.

The timeline occupied by the Dace family was a very large branch of the timeline. It was also abnormally stable and had existed for hundreds of eras. This timeline was almost as long as the existence of humans in this dimension. It was long before the time when the Dace family discovered it. Therefore, it had accumulated a lot of resources.

No one knew how this subsidiary timeline came about. However, the Federal Government had analyzed some information obtained through various channels. The sudden disappearance of the Dace family dozens of eras ago was because the entire family had moved into this timeline.

Gu Ding followed Hermean Alliance's spaceship to the location designated by the Federal Government. Liliath and the others had long been taken into his Miniature World.

The federal government did not give Hermean Alliance many slots, only a thousand. Therefore, Hermean Alliance only sent ten spaceships.

Through the window of the spaceship, Gu Ding saw the spaceships of other forces around him. There was the Freedom Alliance, Divine Weapon Pavilion, and some other forces that he was not familiar with.

"Looks like the Federal Government has really gone all out this time. Just their organization alone has mobilized thirty thousand people, all of whom are high-rank True Gods. Some of the other organizations had also dispatched hundreds to thousands of people, and all of them were middle-rank and high-rank True Gods. Your battle prowess can only be considered below average among this group of people. " The results of Neptune's scan surprised Gu Ding because he had no idea that there were so many true god-level powerhouses in the human Cosmic Sea.

Several hundred super warships gathered in the void, each bearing the insignia of the various major powers. The occasional merchant ships and cruise ships that passed by were baffled by this sight. Many people immediately took photos of the spectacular scene and posted them on the Skynet.

At first, many people angrily rebuked the people who took the photos, saying that they were fake photos, because it was unlikely that these forces would work together. However, as the number of photos increased, and even videos appeared, people finally believed that the scene was real. There was a lot of discussion on the Skynet, and all kinds of guesses about what was going on.

Some of the small and medium-sized forces that were not invited soon noticed this. Many of them guessed the reason why the Federal Government had joined forces with these huge forces to go on an expedition, and they began to pay attention to the movement of the incident. If they brought back enough resources from the expedition to another Time Dimension, it was very likely that the development of the entire human race would be greatly improved. This was what almost everyone wanted to see.

"There are also a few particularly dark auras. They should be Heavenly God-Level powerhouses who have returned from a higher dimension. It seems that their combat effectiveness is suppressed to a certain extent by the Base Dimension, and they can't fully display it. "Neptune also found out some information about Heavenly God-Level powerhouses.

"It seems that the Federal Government is serious this time." Gu Ding was also thinking about how to save Hark.

"There are quite a lot of people participating in the expedition this time …" A voice suddenly came from behind Gu Ding. Gu Ding did not need to turn around to know that the person who spoke was Belanger, who had lost to him in medicine refinement.

"Unfortunately, it doesn't matter how many people there are." This sentence came from Belanger through voice transmission. No one but Gu Ding heard it.

Hearing this, Gu Ding frowned slightly and asked through voice transmission, "In other words, there are Heavenly God-Level powerhouses in your family?"

Seeing the calm expression on Belanger's face, Gu Ding added, "And there are more than one Heavenly God-Level powerhouse?!"

As soon as this sentence came out, a look of discomfort flashed across Belanger's face. Although he quickly covered it up, Gu Ding and Neptune still caught it.

"In any case, your expedition won't be able to get anything out of this. Your Time Dimension guys are too weak," Belanger said confidently to Gu Ding through voice transmission.

"Their victory or defeat has little to do with me. My goal is to save Hark. Don't forget the bet between us." Gu Ding really did not care about the outcome of this expedition. As long as the Federal Government and the other forces could attract the Days family's attention, it would be enough for him to save Hark.

"Of course I won't go back on my word. I'll help you save Hark, but no one knows if you can leave that Time Dimension alive. It'll be a mess when the time comes," Belanger said as he looked Gu Ding up and down. "With your strength, you'll only be cannon fodder if you participate in an expedition of this level. To be honest, if you're smart enough, you'll never get involved in this mess. "

"Don't forget, you lost to me in medicine refinement. If I'm not smart enough, you won't be any better. Besides, you only need to help us save Hark. As for the rest, you don't have to worry about it. "Gu Ding's words made Belanger speechless.

After some preparation, the Federal Government finally opened the time wormhole. First, they led the fleet through the wormhole, and the other forces' teams immediately followed.
