At the instant the two lines of work commenced simultaneously, in reality, Quan Yi also had a very important third line of engineering that was quietly operating.
At the very bottom of the Naruto space, Huo Wu arrived at her favorite window borderline.
In the dim space, as she approached, a rippling golden water surface appeared in front of her.
Through the water surface, in Huo Wu's vision, a vast expanse of the universe appeared.
In the endless scenes, the stars of the solar system were in motion, presenting in real-time in her mind.
However, what Huo Wu observed first was not the dazzling array of images; what she wanted to focus on was an extremely small object located near the sun, flying at high speed and continuously approaching it.
When Huo Wu quickly zoomed in on the image, a small dragon-shaped object appeared in the perspective she shared with the sun as a light source.
Although Huo Wu could only judge its shape through the reflected shadow, its shape was exactly the same as that of Xiao Jin coiled on her shoulder.
From this highly symbolic feature, it was easy to judge that it was the dragon soul separated from Quan Yi.
More precisely, this was Xiao Hong, who had advanced to the God-level.
At this moment, in the distant universe, Xiao Hong was in the silent and boundless space, using the fire from its tail to propel itself at a speed exceeding its limit on Earth, heading straight for the giant fireball in front of it.
That giant fireball was the eternal torch suspended above humanity's head, the sun.
According to the distribution of the solar system, the distance between Xiao Hong and the sun was closer than the distance to any planet.
Although the temperature of the surrounding universe was extremely low, Xiao Hong's surface temperature rose to over six thousand degrees Celsius due to continuous exposure to the radiant energy released by the sun, especially under the intense direct sunlight.
As for why Xiao Hong appeared in a place so far away from Earth, the origin of this matter can be traced back to a week ago.
Quan Yi, who officially started the soul ring research, thought about all the necessary elements for the experiment before starting the research.
Since he was going to study soul rings, then a large number of different soul rings were definitely the most necessary existence; at the same time, the soul rings would eventually be combined with the human body to determine their effect.
Fortunately, this part was well resolved.
However, another important factor lacking in the experiment was energy, power!
It should be known that the energy required for the God-level soul ring that Quan Yi ultimately planned was definitely insufficient with Quan Yi's accumulated divine power alone.
How much food and energy does a normal soul beast consume to advance from a hundred years to a thousand years?
How much energy is required for the qualitative change from a thousand years to ten thousand years?
Ten thousand years to one hundred thousand years, one hundred thousand years to one million years...
The energy required for the latter two qualitative changes is simply a bottomless pit.
According to Quan Yi's speed of absorbing energy, at that time, the space within hundreds of miles around him would fall into a forbidden zone of elements.
After all, to achieve the accumulation of a soul beast for hundreds or thousands of years, some price must be paid.
Of course, Quan Yi could also supply energy to the soul ring by intercepting the energy from the Ice and Fire Springs.
However, he also discovered that the energy of the spring water was not truly infinite; as long as Quan Yi absorbed it quickly and in large quantities, the energy density of the spring water would also decrease.
This point became more obvious after the two completed the full set of upgrades to the soul bones.
Upgrading the twelve soul bones to the demigod level or above was already an incredible thing.
Although the spring water could dynamically balance the energy density to a certain level, if this balance was completely broken, it would suffer permanent damage.
In order not to destroy this treasure land and to preserve the environment of the medicinal garden, Quan Yi could only seek other sources of energy.
At first, Quan Yi also wanted to find another treasure land that might exist on the continent, but when he was considering the ultimate light, he suddenly looked up and saw the huge sun.
When it comes to energy, what in the entire universe could be hotter and more dazzling than a star?
In the past, even if he saw the sun, he could only fantasize about it, but now, Quan Yi had the ability to turn fantasy into reality.
Quan Yi, who 'saw' the sun again, had bright eyes and immediately decided to use the sun as an energy source to supply his experiments.
After setting the goal, it was difficult to achieve this goal with Quan Yi's power alone.
Because the planet he was on was too far away from the sun, and outer space was not suitable for living beings to live in for a long time, let alone cross-planetary leaps.
However, what must be remembered was that Quan Yi was not alone.
To achieve this goal, another person was needed, namely Huo Wu's full assistance.
The Light and Shadow Domain possessed the ability to transfer space across light sources.
Moreover, Huo Wu could also resonate with the sun, which meant that she could connect to the shadows reflected by the sun and transfer objects to any location.
Combining Huo Wu's terrifying long-distance projection ability, the two worked together to transfer Xiao Hong to the planet closest to the sun, which, according to Earth's situation, was Mercury.
Huo Wu's teleportation had to rely on shadows, so the dark side of this 'Mercury' became an excellent projection location.
After selecting the location, the next step was to select the candidate.
Regarding this candidate, Quan Yi almost did not hesitate and directly selected Xiao Hong, who had advanced to the God-level.
Possessing a strong body made of Ultimate Gold, a high-performance aircraft that could continue to operate relying solely on pure fire elemental energy.
If asked who was most suitable for this difficult inter-planetary flight mission, it had to be Xiao Hong.
At first, Xiao Hong, who was projected to Mercury, was too far away from the sun to capture enough energy to maintain high-speed propulsion, so Huo Wu would regularly transmit her own energy through the shadow it projected in her spare time from cultivation.
However, today, Xiao Hong had completely gotten rid of the energy transport from the planet.
Noticing this, Huo Wu's face showed a happy expression.
She took off Xiao Jin from her shoulder and used it as a megaphone-type soul guidance device to contact: "Xiao Hong, can you hear me?"
Xiao Jin's dark golden pupil on the right quickly dimmed, and obvious vermilion fluorescent light began to cover its right eye.
Its expression also changed from cold to lively, with a warm expression, and the whole atmosphere was completely like Xiao Hong.
After completing the change, Xiao Jin began to speak with completely different personality characteristics, saying: "Mother, I am here."
At this moment, it was Xiao Hong, who was far away near the sun, who was speaking through Xiao Jin's body.
"Report the situation!"
"Mother, I have successfully approached the vicinity of the sun's atmosphere, wait, the temperature here seems a little wrong."
