Tenglong Nebula, also known as the Double Star Graveyard.

According to technical support intelligence provided by the Empire's Intelligence Bureau from the Royal Academy of Sciences, there once existed a complete twin star system composed of two large main sequence stars.

The masses of these two main sequence stars were thirty-seven times and sixty-six times that of the Source Sun, with volumes six billion times and thirty million times that of the Source Sun respectively.

A billion years ago, these two stars in their prime suddenly exploded. The energy released during their explosion even surpassed that of a supernova explosion. Additionally, astrophysicists at the Royal Academy of Sciences believe that the explosion of this twin star system is unrelated to the black hole above, and there are no traces of any large celestial bodies passing through here. The reason for the explosion is quite mysterious, and can only be speculated to be influenced by some kind of cosmic ray burst.

The terrifying explosive impact not only released high temperatures outside but also instantly generated an entire periodic table of elements.

The two stars were torn apart into fragmented "corpse fragments," scattering throughout space.

Some of the dispersing matter flying upward entered the gravitational range of the black hole and was gradually absorbed into the black hole.

The rest of the dispersing matter, after undergoing ten billion years of cooling and condensation and other evolutions, was shaped under the gravitational effects of the black hole above, the central large black hole of the Ancient Disk Galaxy, and countless other celestial bodies, into the shape of a dragon from ancient myths of past Source Star civilizations.

This dragon is approximately 2.2 light years long, with a dragon body diameter of about 0.2 light year, and a rotation period of nearly fifty million years, currently almost perfectly positioned between the Source Star and South Nine Star. The fleet needs to traverse through the dragon's body.

Within the dragon's body, myriad scattered star dust and plasma fog clusters are distributed. There are also planets of various sizes.

No, these celestial bodies cannot be called planets. More accurately, they are solid, gaseous, and liquid spherical celestial bodies, as well as various space meteorites of different shapes.

The surface environments of these celestial bodies are complex and variable, with temperatures approaching absolute zero, and also thousand-degree high temperatures, alongside several hundred degrees of "normal temperatures."

"Normal temperatures" and high temperatures typically originate from thermonuclear fusion and other reactions inside these super-sized solid celestial bodies. Their surfaces are not completely dark, featuring background light composed of countless starlights within the Star System, and possibly faint light from flowing red magma on their surfaces.

Ren Zhong stood with his hands behind him in the combat command room, just awakened not long ago.

Zheng Tian, who had awakened even earlier two months ago, stood on his left side.

Ten years ago, Zheng Tian returned after leaving, taking over the responsibilities of overall coordinator of enhanced military training from Ren Zhong and Vincent, reorganizing the training plans from start to finish, and making targeted adjustments for each armed battleship, converting ten transport ships into training ships.

At that time, Zheng Tian was busy for half a year before returning to cryogenic sleep, maintaining a fixed wake-up period of one month each year.

Zheng Tian completed her work excellently.

A little farther on the other side, Qian Wangshen, who was in charge of military scientific research projects, was searching data with some difficulty seated in a wheelchair.

Unlike others who followed Ren Zhong throughout Starfire Town, Qian Wangshen joined midway. He rarely interacted with ordinary people, and most of his direct subordinates followed the fleet for the Great Migration. His feelings for those who remained on Source Star were not so deep. Perhaps, as a researcher, he naturally had a more rational mindset. He wasn't so concerned with details, only the final right or wrong. He never opposed Ren Zhong's decisions.

Over these ten years, Qian Wangshen undertook the heaviest research tasks without resting a single day, turning him elderly and frail.

But like Sun Miao before him, Old Qian's lifelong contributions yielded many achievements and cultivated a large number of successors.

Besides the aforementioned core personnel, there was another familiar face in the command room, Zhuo Yihang, Ren Zhong's assistant from the time he entered the Census Official College.

Ren Zhong saved his life from the flow of time and arranged for him to start as a grassroots management staff in Starfire Town.

His progress was not very fast but steady, advancing step by step.

For thirty years, Zhuo Yihang experienced only about fifteen years of cryogenic sleep, especially after joining the Great Migration Fleet.

After most other core associates chose sleep, Zhuo Yihang decided to unconditionally follow Ren Zhong, volunteering to take on more responsibilities, helping Ren Zhong alleviate difficulties.

This time, he started from the grassroots of the fleet's administrative department.
