This was the first time Quan Yi had encountered such a situation.
“The Fire Dragon King's will seems to be rejecting the aura of the necklace. If I forcefully put it in, the energy of the soul bone might cause the entire storage space to collapse.
This is terrible!”
The seemingly extremely stable artifact, the Heart of Scorching Sun, was showing Quan Yi its fragile side for the first time when faced with the Fire Dragon King's torso bone of the same level.
Even artifacts have their limits?
Although this unexpected situation occurred, Quan Yi didn't panic too much.
Since it couldn't be stored in the Heart of Scorching Sun, it would be better to just leave the soul bone at the bottom of the spring. The high-temperature, high-pressure spring water doesn't have fire immunity, so even a Peerless Douluo wouldn't be able to reach this location.
Moreover, who else would think that the Fire Dragon King's soul bone would be buried here besides him?
Thinking of this, Quan Yi comforted the soul bone and turned to leave the bottom of the spring.
A moment later, Quan Yi's dragon head emerged from the spring, transforming into a human form in the air.
“How is it? Is there a soul bone?”
Huo Wu asked Quan Yi expectantly.
Quan Yi smiled and replied, “Yes, and it's a precious torso bone.”
“What a pity, it's just the missing position!”
Huo Wu showed a regretful expression.
Quan Yi quickly stepped forward and hugged Huo Wu tightly, saying with heartache, “I know your intentions, so you don't need to do this.”
Huo Wu's brain short-circuited when she was suddenly hugged, and the excuse she had prepared in advance was completely blocked.
“Mm.”
The usually boisterous Huo Wu revealed a shy whimper in Quan Yi's embrace.
Quan Yi released his embrace, lowered his head, and looked at Huo Wu, who was blushing and looking down, with a sly smile on his face.
This seemingly selfless act is, in a sense, the most selfish behavior.
Because, in the subconscious of both of them, the other has long become a part of themselves.
“Xiao Wu, I'll absorb this soul bone.”
Huo Wu nodded in response, “It should have been done a long time ago.”
After completing the exploration task, Quan Yi and Huo Wu returned to the wooden house to tidy up their room.
However, since they had only been away for a little over a month, there wasn't even much dust in the sealed house.
After a simple cleaning, they officially entered a state of closed-door cultivation.
Huo Wu's cultivation task was relatively simple, as she only needed to maintain her previous cultivation content.
In the past ten months, Huo Wu's body had been able to fully adapt to the scouring of the Scorching Sun Yuan Power.
In this state, even without using her sixth soul skill, Phoenix's Protection, she could stay around the spring for a long time.
This also meant that Huo Wu could maintain a state of automatic cultivation for a long time.
Relying on this, Huo Wu would definitely be able to cultivate to level seventy within the next year.
Having talked about Huo Wu, it's time to talk about Quan Yi.
After Quan Yi's breakthrough, his physical fitness had improved sharply. Only by adding all the equipment together could Quan Yi barely feel the burden.
However, in this way, the overly bloated load would instead hinder Quan Yi's movements.
Without being able to further compress the density of the metal, Quan Yi could only search for another body training method.
Fortunately, Quan Yi had already found another, more efficient and comprehensive body training method.
That was the water pressure body forging method.
The spring water, reaching a depth of 30,000 meters, would have an extremely terrifying water pressure at the bottom.
Previously, Quan Yi seemed to be very relaxed, but that was only possible because Quan Yi had a dragon body made of Extreme Gold.
If he only relied on his physical body, Quan Yi's current limit was only barely being able to dive to a depth of 10,000 meters.
At this depth, the power of the water pressure would break through the level of one million kilograms.
Being squeezed by a force of one million kilograms, even Quan Yi's body, which was comparable to indestructible, wouldn't be able to withstand it for long.
However, the water pressure could be adjusted according to the depth, and this pressure came from all directions. Conducting body training in a water pressure environment close to the limit would definitely be more effective than on land.
Not long ago, Quan Yi had just completed the soul-guided version of the oxygen mask, which could support him in high-intensity underwater training for a long time.
Moreover, in addition to water pressure, Quan Yi also thought of the body forging effect brought about by the strong vibrations when he reforged his martial soul.
If water pressure was external squeezing, then vibration was a force that could directly reach the inside.
Under the extremely penetrating vibration, all the fragile parts of the body would be exposed.
Therefore, Quan Yi planned to use the power of vibration in a water pressure environment to allow his body to receive both internal and external training.
As for how to cause vibration, don't forget that Quan Yi had just obtained the Flame Dragon King's left leg bone.
The left leg bone soul bone skill, Dragon Scale Turbulent Flow, could produce extremely powerful vibration.
Through precise soul power control, Quan Yi could control the intensity and direction of the vibration.
Soul bone skills don't necessarily have to be used for combat. As long as you change your way of thinking, it can also become a tool for training.
After determining the body training method, Quan Yi took out a ruby from the Heart of Scorching Sun while Huo Wu was not around.
This ruby was the one Quan Yi obtained from Quan Yue.
Back then, after the Quan family obtained this ruby, Yun Qiong specially gave it a unique name to distinguish it from other rubies.
“Phoenix Blood Ruby.”
This was the name of this ruby.
Generally speaking, the mineral ruby is extremely rare due to its extremely harsh conditions of birth, and it can only be mined in specific areas.
Moreover, most of the rubies that are mined are extremely fragmented or have obvious flaws.
Therefore, there are very few that can be used as gemstones.
Ordinary rubies are graded according to their color.
The highest grade ruby is called 'Pigeon Blood Red'.
This ruby will have a vivid color with a deep red tone, giving people a feeling of purity, brightness, and saturation.
However, the mineral ruby will inevitably have impurities invisible to the naked eye inside due to the special environment in which it was born.
Some are other metals, and some may be other gases or solids.
Even if the transparency and purity of the ruby reach the highest level, it can still be seen if carefully magnified.
This flaw in rubies can be said to be unavoidable.
In fact, sometimes this flaw can better prove the naturalness of the ruby. Therefore, as long as it is not a flaw visible to the naked eye, it will not affect the value of the ruby.
However, the Phoenix Blood Ruby in Quan Yi's hand is not only more vivid in color than the highest grade Pigeon Blood Red, but more importantly, it has no impurities inside.
