The new enterprise's inaugural official voyage concluded successfully several weeks later.
This journey not only verified the stability of the Level Eight Warp Engine but also subjected the Void Shield system and the directional reconstruction system to initial tests in a real space environment.
Osiris' database was filled with detailed operational parameters and performance reports, and this firsthand data far exceeded his expectations.
After the voyage, in a conference room at Starfleet Headquarters, Osiris formally bid farewell to Kirk, Spock, Scott, and several high-ranking Starfleet officials.
"The necessary test data has been collected," his synthesized voice stated calmly, "I plan to return to my dimension.
This exchange has been fruitful, and I thank you all for your cooperation."
A brief silence fell over the conference room.
Kirk stepped forward, looking at him sincerely: "Mr. Osiris, Starfleet sincerely hopes you will stay.
You have brought not only technological breakthroughs but, more importantly, unconventional ways of thinking.
Your departure would be a significant loss to us."
The captain couldn't help but recall the moments of crisis they had shared—from the groundbreaking advancements in Warp Drive theory to the stasis grenade that turned the tide at critical moments, and the philosophical discussions that sparked deep contemplation.
Spock, with his characteristic rational demeanor, added: "From a logical perspective, your continued involvement would significantly enhance Starfleet's research and development efficiency in fields such as materials science and energy physics.
The knowledge systems of the two civilizations are clearly complementary, and maintaining communication holds long-term value for both parties."
Scott couldn't help but scratch his head, his tone carrying the straightforwardness peculiar to engineers: "Honestly, who are we going to consult for those unique solutions when we encounter tricky engineering problems in the future?"
He was referring to Osiris' unique ideas that integrated engineering from another world.
An official from the Science Council, dressed in a formal uniform, stepped forward and made an official statement on behalf of Starfleet: "Mr. Osiris, in recognition of your outstanding contributions to Starfleet's technological development, we have granted you the status of Honorary Scientist.
We have prepared excellent research conditions and ample resource support for you, and we hope you will reconsider your decision."
Osiris' gaze swept over everyone present; he could discern sincerity and respect in their pleas.
During this time, he had indeed established an effective mode of cooperation with these Starfleet elites.
"My itinerary is set," Osiris' synthesized voice calmly replied, then changed the subject, "However, this departure is not a permanent farewell.
I have recorded the coordinates of this dimension, and when conditions are suitable, I will visit again."
He deliberately paused for a moment, letting the information sink in among them.
Just as everyone was still processing this news, he continued: "The exchange of knowledge should not cease here.
Perhaps next time we meet, I will bring some... more challenging topics, and at that time, I will need to rely on your professional capabilities to solve them together."
His crimson optical lens slowly swept over Spock and several chief scientists, implying that unrevealed technical problems involving more profound principles were awaiting the right moment for discussion.
This farewell, delivered with a clear promise, effectively eased the solemn atmosphere of parting.
Kirk and Spock exchanged a knowing glance; they both understood that for an entity capable of freely traversing dimensions, conventional pleas to stay were indeed meaningless.
To receive a promise of return and to continue this mutually beneficial knowledge sharing was already the most ideal outcome under the current circumstances.
—
At the main banquet hall of Starfleet Headquarters, a solemn farewell ceremony was underway.
This arched dome hall, a historic site where the Starfleet Charter was signed, now gathered members of the Starfleet Science Council, high-ranking admirals from Starfleet Command, and core scientists who had participated in the cooperation project.
Kirk, in his formal dress uniform, was adorned with medals symbolizing distinguished service.
He stood at the podium in the center of the hall, his voice steady and powerful: "On behalf of Starfleet, I extend our highest gratitude to Mr. Osiris.
During this period of cooperation, you not only helped us break through technological bottlenecks but, more importantly, taught us to view the relationship between science and civilization from an entirely new perspective."
The Chairman of the Starfleet Science Council also delivered an official address, announcing Osiris' designation as "Starfleet Honorary Science Advisor" and awarding him the highest Starfleet Science Contribution Medal.
Twelve authoritative scholars from various scientific fields successively stepped forward to engage in academic farewell exchanges with the visitor from another world.
Osiris' mechanical body gleamed with a dark red luster under the brilliant crystal chandeliers, and he maintained a dignified and courteous demeanor throughout.
He inclined his body slightly when receiving the medal; patiently answered technical details when conversing with scholars; and provided appropriate responses to official addresses.
These gestures all reflected his appreciation for this cross-dimensional cooperative relationship.
After the grand farewell ceremony, in accordance with Osiris' wishes and safety protocols, the new enterprise undertook the final escort mission.
This starship, having just completed its maiden voyage, now carried the mission of seeing off its friend from another world, adjusting its course and steadily heading towards the planet where the Genesis Cavern, where Osiris first arrived in this universe, was located.
In a relatively open area deep within the cavern, Osiris stopped.
Maine's team had already assembled, standing silently behind Osiris.
Osiris' massive mechanical body turned towards the direction of the cave entrance, as if he could see the waiting starship through the rock wall.
He did not send any further communication; his crimson optical lens flickered slightly as he began to execute a complex and precise operation.
As energy converged, the space in the center of the cavern began to emit a low hum, and a highly unstable dimensional rift, similar to the one he arrived through, was torn open again, its interior shimmering with flowing light and emitting unsettling unknown energy fluctuations.
The moment the rift stabilized, Osiris turned back towards the Enterprise and sent his final, concise communication: "Depart."
Without further words, he took the first step, his massive body plunging unhesitatingly into the kaleidoscopic rift.
Maine's team followed closely, their steps firm, entering one by one, their figures swiftly swallowed by the distorted light and shadows.
On the bridge of the Enterprise, Kirk, Spock, Scott, and others watched it all in silence through their sensors.
They watched as Osiris and Maine's team disappeared into the depths of the rift, and as the passage that had briefly connected two worlds began to violently fluctuate and contract, finally closing completely like a healing wound within the normal spatial structure, leaving no trace.
The cavern returned to darkness and silence, as if nothing had ever happened.
Only the new enterprise, still hovering in place, proved that the cross-dimensional farewell they had just witnessed was not an illusion.
Kirk gazed at the empty space on the main viewscreen for a long time, then softly gave the command: "We are returning to base."
The new enterprise gracefully turned its bow, its engines emitting a soft glow.
