During his year in the Land of Light, Chen Yu dedicated his time to learning various universal knowledge.
Before leaving the instance world, Chen Yu planned to ask Hikari to create some useful gadgets for him.
Of course, he wouldn't request items like the Geed Riser or the Z Riser at this time.
Not to mention Hikari hadn't created them yet, even if they were made, such items were precious in their initial phase and not widely replicable until later.
Besides, Chen Yu already had the Geed Riser!
So, Chen Yu's wishlist was simple, consisting of items Hikari could easily create.
For instance, a language translator, similar to the one Juggler made in Tiga's world, that could translate any language into human language through special waves.
Compared to Earth-made devices, the Land of Light's language translators were far superior.
Given the Space Garrison's frequent visits to other planets, interacting with various species was inevitable, making a translator necessary.
Thus, the Land of Light's translators were special energy capsules that, once merged into the body, allowed understanding and communication in any language.
Naturally, communicating with some brainless monsters could be problematic, as some were purely non-communicative.
The language capsule integration went smoothly, and Chen Yu no longer faced language barriers.
Storage was another concern for Chen Yu.
Ultras from the Land of Light generally had innate item storage abilities, like Hikari, who could summon a virtual screen to retrieve stored items.
Chen Yu learned from Hikari that this was called an extradimensional storage space, a technological product developed by the Research Bureau's Ultra Scientists.
A small space rune tattooed on the finger was all it took to activate this ability.
Chen Yu, unwilling to miss out on extradimensional storage, had Hikari inscribe a mini storage rune on his finger, which remained hidden under normal circumstances and was not easily detectable.
Chen Yu tested the rune; it worked in human form, activated by mere intention, with item storage and selection managed through a virtual screen swipe.
Though a scientific product, it felt almost magical to Chen Yu.
Having resolved communication and storage issues, Chen Yu had no further requests.
Whether it was the Ultra Bracelet, translation capsule, or storage rune, these were commonplace for Ultras from the Land of Light.
Of course, the Ultra Bracelet was a combat tool typically carried by younger Space Garrison members, not a common item for all residents of the Land of Light.
Chen Yu actually wanted a spaceship too.
However, such a vessel held considerable value in the Land of Light, and given the size difference between Ultras and humans, Chen Yu needed a ship suitable for human use for other instance worlds.
Frequent visits to the Research Bureau allowed Chen Yu to often see Zero, Hikari's assistant.
As expected, Zero, driven by a quest for power, did not intend to remain just a scientist.
In his words, even as a scientist, one should aspire to be as strong as Hikari, capable of tearing apart monsters like Bemstar with bare hands.
But Hikari, engrossed in research, had little time to teach Zero combat skills.
When the Land of Light was invaded by Belial, Zero was still in the Research Bureau and got frozen halfway there by the freeze storm caused by the removal of the Plasma Spark.
Chen Yu also learned why Seven didn't use the Ultra Barrier to block the storm as in the original storyline.
It was because Seven saw Zero flying over and attempted to help him with a barrier.
Unfortunately, they were too late and got frozen together.
As for why the Original didn't use a barrier... it simply hadn't occurred to him.
After all, in the original storyline, there was Seven to create a barrier together, and the Original Ultraman, capable of blocking lightning with his pectorals, really didn't bother with an Ultra Barrier.
...
Another year passed.
Since Chen Yu had already self-taught boxing and Wudang Long Fist, along with the awarded Space Martial Arts, he only practiced occasionally and didn't learn more combat techniques.
Instead, he spent his time attending knowledge classes with the new Space Garrison recruits in the Land of Light.
The curriculum in the Land of Light was rich, covering the weaknesses of various monsters and aliens and teaching about other planets.
For instance, Earth's bicycles, motorcycles, cars, and other transport vehicles.
Seven's proficiency in driving on Earth had a reason.
Besides conventional vehicles, knowledge on piloting fighter jets, boats, submarines, tanks, etc., was also part of the curriculum.
Since the Ultra Brothers' experiences on Earth showed that Ultras typically joined Earth's defense teams, it was better to practice in the Land of Light than waste precious time learning on Earth.
With various knowledge skills learned, Chen Yu felt satisfied. After collecting several substantial gold nuggets from the universe, he decided to leave the instance world.
After consulting with Seven, Chen Yu learned to purify radiation and harmful substances from the gold, cleaning them thoroughly.
Finally, he bid farewell to Father of Ultra.
With many friends from the Land of Light seeing him off with reluctance, Chen Yu chose to leave the instance, disappearing from this world.
In a quiet room, Chen Yu's figure suddenly appeared.
Surrounded by a familiar yet unfamiliar environment, Chen Yu felt a sense of temporal displacement, having spent two years in the Land of Light before returning to the reality of Earth.
With a wave of his hand, a virtual screen appeared before Chen Yu, displaying photos of the gold stones.
