Discovery of a Mineral Vein
This location is very close to the Upper Mantle.
The Upper Mantle is a transitional layer composed of molten material that is nearly a thousand kilometers thick.
Calling it a Sea of Lava is not an exaggeration at all.
The energy contained within is something Quan Yi could never have imagined.
Unbeknownst to him, Quan Yi had already descended into the Mantle Layer, a depth beyond the reach of any living being.
After admiring the scene for a moment, Quan Yi regained his composure and began to investigate the potential dangers.
Here, the high temperature brought about by the high-pressure environment can amplify the effect without Quan Yi needing to actively absorb it.
When Quan Yi activated the Scarlet Dragon Horns, the immense Fire Element energy was rapidly converted into Quan Yi's Soul Power to replenish what he had consumed.
"Flame Senior, if we're mistaken, could it be a potential threat to Blue Silver Island?"
Without needing the Flame Dragon King's reminder, Quan Yi used his Dragon Pupil to observe the anomaly.
A long line of molten lava was seen extending from the high-temperature molten material of the mantle along the weakest part of the Earth's crust.
Unlike a river, this is a tributary that branches off from the Sea of Lava, and then flows upwards.
"Indeed, this tributary is rising steadily under pressure."
Most of them will cool down and solidify along the way, but some will burst out of the ground and cause volcanic eruptions.
However, this molten lava did not appear to solidify.
Based on its experience, the Flame Dragon King analyzed the possibility of a volcanic eruption.
Seeing this, Quan Yi was not alarmed. He quietly watched the lava slowly spreading upwards, and an idea popped into his mind.
"Flame Senior, if the hidden danger on the Sea Island is this, I think we should be able to solve this problem."
The Flame Dragon King smiled and said, "Yes, fortunately it involves molten lava, otherwise it would have taken a lot of effort to solve it."
However, this matter requires further consideration; let's first probe the specifics of the situation.
The conversation between the two was much more relaxed than before.
Taking advantage of its environment, Quan Yi can explore the underground conditions for extended periods of time.
In order to further conserve Soul Power, Quan Yi embedded himself from the rock strata into the Upper Mantle, which was full of molten material.
When the Dark Gold Yang Dragon dives into the Upper Mantle, it is like a dragon returning to the sea, and it can roam the depths of the earth without even activating the Volcano Domain.
The intense heat cannot damage it, and the low pressure makes this environment paradise for it.
Using the Upper Mantle layer, Quan Yi quickly surveyed the geological conditions within a radius of hundreds of miles.
Quan Yi conserves and restores his Soul Power by repeatedly moving between the solid layer and the molten layer, thus enabling him to maintain his Martial Soul Avatar for a long time.
Just as he was gathering intelligence, Xiao Jin, hidden within his Martial Soul, let out an excited dragon roar.
It roared anxiously in one direction.
This was the first time Quan Yi had ever seen the usually quiet and composed Xiao Jin act so excitedly.
The Flame Dragon King also sensed something and said, "Quan Yi, you are very lucky."
Just as Quan Yi was feeling puzzled, Xiao Jin conveyed its meaning through Spiritual Communication.
It said it smelled a scent it liked.
It was at this moment that Quan Yi suddenly realized what was going on. Without saying anything, he swam directly towards the upper level.
As they drew closer, without needing to use Xiao Jin's physical form, Quan Yi felt a magnetic-like sensation through the body of the Dark Gold Yang Dragon.
At the same time, Quan Yi could feel the Metal-attribute Soul Power within his body beginning to throb with excitement.
Just then, Quan Yi finally arrived at his destination.
A massive vein of minerals radiating Metal-attribute energy.
"I'm going to get rich!"
Quan Yi stood frozen in place, only that sentence echoing in his mind.
An hour later, on the western coast of Blue Silver Island, Huo Wu noticed a familiar aura appearing in the Sea Area several miles away.
She immediately called to Quan Li and Yun Qiong, saying, "Look, Xiao Yi is out."
The next moment, a majestic, heterochromatic-eyed Divine Dragon leaped out of the water and flew towards them.
The Dark Gold Yang Dragon was extremely fast, reaching the shore in a single tail swing, and then transforming back into fluorescent light in mid-air, reverting to its human form.
As soon as Quan Yi landed on the ground, Huo Wu began to question Quan Yi.
"Are you hurt?"
Quan Yi gently ruffled Huo Wu's hair and smiled, "No, everything went smoothly."
Yun Qiong asked, "How is it? Is the situation serious?"
"It's much better than I expected. I think we don't need to move away from the island."
Then Quan Yi briefly described the situation underground and finally offered a solution.
"This is caused by the collision of rock layers, resulting in Underground Magma. It is still very deep and will not affect the Sea Island in the short term."
However, to better eliminate the hidden dangers, it is necessary to guide the magma to flow in other directions and prevent it from continuing to accumulate.
Fortunately, the problem isn't too serious at this stage, and we have plenty of time to deal with it gradually.
Now, everyone could finally breathe a sigh of relief.
At this moment, Quan Yi smiled slightly and continued, "Moreover, during this dive, we also discovered that there are many mineral veins beneath Blue Silver Island."
Once these ores are mined, we won't need to go through the trouble of transporting various metals from the land; we can forge all the necessary equipment right here.
"Really!"
The series of surprises filled Quan Li and Yun Qiong with immense excitement.
The scarcity of metallic minerals was the biggest challenge facing the Quan Family.
Iron ships, Steam Engine, agricultural machinery, and other things related to development all required the consumption of enormous amounts of metal.
To be honest, the minerals that the Quan Family has purchased in recent years are basically equivalent to the metal consumption of a kingdom for twenty years.
It's actually quite unbelievable that a family with a total population of only around 100,000 would consume such a huge amount of metal.
However, the amount of metal mining in the entire Douluo Continent is limited, and in order to avoid being detected by the authorities, the number of mines controlled by the Quan Family cannot be too exaggerated.
This led to an even greater craving for metals.
Now that they heard Quan Yi say there were minerals underground on Blue Silver Island, they were naturally happy.
"Yes, I have noted down the locations of the shallow veins. Once we have enough manpower, we can start mining and refining."
Detecting minerals is another application of Vibration Perception.
By observing that vibrations travel at different speeds in different materials, different foreign objects buried underground can be detected.
Ores are the most obvious example of this.
It was at this moment that Quan Yi truly understood the terrifying nature of Vibration Perception.
Exploring geology and searching for minerals—tasks that typically require complex technical methods and knowledge—are things that Quan Yi can easily do on his own.
What's the difference between searching for minerals and picking up money directly from the ground?
Quan Yi increasingly felt that choosing the Sea Iguana Flame Dragon King first among the four Hundred-Thousand-Year Soul Beast was the best decision he had ever made.
The other three Hundred-Thousand-Year Soul Beast combined might not be as effective as the Flame Dragon King alone.
