However, even with an expanded selection range, head spirit bones remain the rarest of all.
Even if they exist, they might not meet Quan Yi's requirements.
For now, Quan Yi can only reduce the intensity of the vibrations.
The weakness of the torso can be addressed by relying on the Dragon Turtle Shedding to restore its condition and catch up with the growth of other parts, but the dizziness affecting the brain cannot be alleviated even with Quan Yi's Dragon Turtle Shedding.
However, reducing the intensity significantly lowers Quan Yi's refining efficiency.
Unfortunately, the unbalanced development of various body parts forces Quan Yi to adhere to the limits of the weakest link.
Helplessly, Quan Yi focused the dispersed vibration force on the purification of spirit bone bloodlines.
Bloodline purification of spirit bones can be achieved through vibration sensing, locating the purest bloodline.
Then, by using vibrations that match its frequency, impurities are expelled.
Purifying the bloodline of a spirit bone, although it may slow down the increase in age, the amplification it brings with each added year will be much greater than in an impure state.
In the long run, this will undoubtedly raise the upper limit of the spirit bone.
Moreover, the improvement of the spirit bone will more quickly drive the increase in Quan Yi's overall attributes.
In fact, the surge in body attributes caused Quan Yi's control over his body to decrease significantly. He originally wanted to improve the spirit bone while re-tempering the entire body, but the reality is that he cannot do both at the same time.
After a moment of thought, Quan Yi decisively chose to continue to wildly improve his physical fitness.
The issue of control can be addressed with training after the physical fitness is improved.
But if he were to deliberately pursue control and slow down the improvement of body attributes, it would be putting the cart before the horse.
Dragon Scale Vibration Technique gradually improved.
The improvement of the left leg bone greatly enhanced Quan Yi's control over vibrations, making it increasingly easy to release vibration force against multiple targets simultaneously.
An afternoon passed.
"Roar!"
The left leg bone, which continuously burst out with Dragon Scale Vibration, let out a dragon's roar.
The Sea Iguanodon Flame Dragon left leg bone successfully evolved to three hundred thousand years.
A powerful dragon's might erupted from the left leg, and although the deep dragon's roar was not loud, its deterrent force was extremely strong.
The dual improvement of bloodline purity and age made it stained with a trace of the Dragon King's aura.
Here, the Dragon King refers to the true Dragon King.
Although this aura is still very weak, as long as it continues to absorb sufficient dragon power and continuously purify its own bloodline, it will only get closer and closer to the true Dragon King.
The body amplification brought about by crossing levels greatly increased Quan Yi's body's endurance limit.
Quan Yi stopped vibrating and immediately dived hundreds of meters downward.
According to this trend, Quan Yi felt that he would definitely be able to break through the depth of 18,000 meters today.
Dragon Scale Vibration Technique, activated again.
Before long, it was dusk outside.
Quan Yi's body once again ushered in a time of transformation.
After an afternoon of absorption, Quan Yi's Flame Dragon right arm bone was on the verge of crossing the level limit.
Another dragon's roar.
The hundred thousand year Flame Dragon right arm bone successfully evolved into a two hundred thousand year Flame Dragon right arm bone.
A heat current erupted from the right arm position, flowing to the whole body.
This heat current had the greatest effect on Quan Yi's strength attribute improvement.
Without the dragon scale covering, it is easier to see the changes in appearance.
The evolution of the right arm bone also drove the amplification of all attributes.
Quan Yi's shriveled torso also barely propped up a bit.
Feeling the body's endurance limit, once again raised, Quan Yi did not hesitate to dive downward.
Another few hundred meters distance, although it was less than when the right leg bone evolved, Quan Yi was not anxious.
He still has a spirit bone that is about to transform.
Dusk had faded, and night fell.
After several hours of silence, the Flame Spirit Dragon Leopard right leg bone, whose evolution was slightly slower than that of a pure dragon, was also on the verge of breaking through under the infusion of increasingly rich dragon power.
A roar resembling both a dragon and a leopard erupted.
Successfully evolved into a two hundred thousand year Flame Spirit Dragon Leopard right leg bone.
Another small burst of body attributes prompted Quan Yi's body to step onto another level.
This time, Quan Yi's descent depth was less than that of the Flame Dragon right arm bone, after all, the increase in strength attribute had greater resistance to water pressure.
However, even so, the successive transformations of the three spirit bones allowed Quan Yi's diving depth to officially break through 18,000 meters.
Nearing twelve o'clock in the morning, from the afternoon to now, Quan Yi improved the maximum depth record by a full thousand meters in less than ten hours.
Converted into kilograms, it is an increase of one million kilograms of bearing capacity.
"It's a pity that the weakness of the short board is becoming more and more prominent with the transformation of the spirit bone."
The distance just exceeding 18,000 meters is the limit of the body's short board. Quan Yi's strongest left leg bone has a limit depth of one thousand meters more than the weakest part.
Moreover, this gap is constantly widening with the increase in the spirit bone's age and bloodline purity.
Quan Yi temporarily stopped vibrating and instead fell into thought.
"Absorbing spirit bones is the fastest method, but we can't slow down the progress of cultivation for this reason.
We must think of a way to alleviate this problem."
Quan Yi sank his consciousness into his body and began to observe the internal situation.
Of course, inspecting the internal condition, his eyes became brighter.
"The growth of the spirit bone brings not only an increase in body attributes, but also equally important changes besides these."
Because of the rapid changes in the body, Quan Yi inevitably ignored some more fundamental things.
That is blood and energy!
The complete fusion of the spirit bone, especially the complete fusion of the main spirit bone, will drive Quan Yi's bone function to evolve with the evolution of the spirit bone.
Speaking of bones, it has a very important function, which is hematopoiesis.
The evolution of the spirit bone, in addition to increasing body attributes, has also unknowingly greatly improved various functions of the bone itself.
Hematopoiesis is one of them.
Just now, when checking the internal condition, Quan Yi found that the blood and energy in his body had quietly increased countless times.
"Blood and energy have an amplifying effect on the body. Since the blood and energy in the body have accumulated to this level, then transferring a portion of the blood and energy scattered in the limbs to the weak parts will definitely offset some of the gap."
Since the body is unbalanced, mobilize the blood and energy in the body to balance the body's strength.
Quan Yi immediately began to try to mobilize blood and energy from his limbs under the extreme compression state.
At the beginning, it didn't have much effect, but as Quan Yi concentrated more and more blood and energy into the torso, a magical scene occurred.
The relatively bulging limbs began to slowly shrivel, while the shriveled torso became ruddy and bulging instead.
The situation of strong branches and weak trunk gradually moved towards a balanced direction.
At this moment, Quan Yi's torso condensed most of the blood and energy in his body. Without Quan Yi's deliberate control, in the extremely compressed space, the blood and energy naturally entered every inch of flesh and blood.
