Liu Erlong was absorbing the soul ring, while Dugu Bo was inspecting the body of the Fiery Unicorn Dragon, but unfortunately, no soul bones were produced.
There is a high probability that a high-level ten-thousand-year soul beast will drop soul bones. The higher the bloodline level of the soul beast, the higher the probability of dropping soul bones. Another way is to increase the drop rate of soul bones by slaughtering soul beasts. However, even so, the probability remains very low. Dugu Bo hunted more than 20 thousand-year-old soul beasts in the Sunset Forest and only obtained three soul bones. He was already very fortunate.
The next plan was for everyone to wait for Liu Erlong to finish absorbing the soul ring, then help Flanders hunt the 70,000-year-old Sky Eagle, and finally assist Li Luochen in hunting the mutant Tyrannosaurus Rex. With Liu Erlong, now a Soul Saint, protecting Li Luochen and Dugu Yan, and with Dugu Bo, a Titled Douluo, and Flanders, a Soul Douluo, joining forces, they should be able to take down this Tyrannosaurus Rex.
The king of sub-dragon species is not to be underestimated. Just like the Dark Gold Terrorclaw Bear, a ten-thousand-year-old soul beast can rival a hundred-thousand-year-old soul beast. Caution is essential.
To be safe, Li Luochen asked Dugu Bo to help refine some medicine. Herbs with spiritual properties, such as the Yangshen Flower, could be refined into pills that enhance spiritual power. This was part of the recipe of the Po Yi clan, and Dugu Bo had already prepared it for Li Luochen in advance. As for why he didn't use Wangchuan Qiushui Dew? Dugu Bo knew the effect of Wangchuan Qiushui Dew and planned to reserve it for his granddaughter.
He wanted his granddaughter to have a ten-thousand-year fourth soul ring, though not as extreme as Li Luochen's. A little over ten thousand years would suffice.
Dugu Bo knew that ten-thousand-year soul beasts had the ability of soul vibration. To refine the spiritual attribute elixir, he used all the spiritual attribute herbs that had matured in the Yin-Yang Eyes of Ice and Fire. These included Yangshen Flower, Ningshen Grass, Qihuan Qingling, Ghost Face Ginseng, and others.
Two types of pills were refined. One had a similar effect to the Longing Dew, directly enhancing mental strength. The other could be swallowed when absorbing soul rings to stabilize the mind.
Li Luochen put considerable effort into preparing for the mutant Tyrannosaurus Rex. If it worked, it would be a great success. If it didn't, well, nothing ventured, nothing gained. Cultivators shouldn't fear difficulties—they should just go for it.
About a day later, Liu Erlong completed the absorption of the soul ring, and her soul power reached the peak of level 71. The true form of her martial soul was critical. Since the attributes of the Fiery Unicorn Dragon were very compatible with Liu Erlong, the unicorn dragon's bloodline directly advanced Liu Erlong's dragon transformation. Her dragon head, limbs, and body had all transformed, leaving only the dragon horns and wings to change.
When Liu Erlong uses her martial soul avatar in the dragon state, she is invincible at the same level. She even dares to challenge a Soul Douluo. Although she may not win, dragon transformation is a unique secret technique of the Blue Lightning Tyrannosaurus Rex family, similar to the Great Sumeru Hammer of the Haotian Sect.
"Okay, let's go find the Sky Eagle. This time, Flanders will protect the two children, and Long Yatou and I will engage in the fight."
Dugu Bo gave the order. With his experience, he knew how to battle a 70,000-year-old soul beast. The original plan was for Flanders and Dugu Bo to work together. The Sky Eagle can fly very fast, and a flying quasi-Soul Douluo like Flanders could stop it. But now, with Dugu Bo's left arm bone plus his eighth soul skill, time solidification, they had enough to stop the Sky Eagle, allowing Liu Erlong to deal heavy damage.
The five of them headed towards the Sky Eagle's territory in the Sunset Forest.
After walking for about half a day, they finally arrived. The trees here were much taller and thicker than in other parts of the Sunset Forest. Many bird soul beasts lived in the area—subjects of the Sky Eagle. As one of the overlords of the Sunset Forest, the Sky Eagle had subordinates, but most of them were thousand-year-old soul beasts, who were quickly scared away by Dugu Bo's Titled Douluo aura.
Cry——
A loud eagle cry was heard as the aura released by Dugu Bo startled the Sky Eagle. In its eyes, some humans had violated its territory.
The Sky Eagle was bluish-white, thirty meters long, with a wingspan of seventy meters. Its feathers were sharp like knives, and it looked extremely majestic, like the overlord of the sky, soaring through the heavens.
"Haha, here we go, Long girl! Let's do this! Seventh soul skill, Golden Phosphorus Snake King's true form!"
"Seventh Soul Skill, Red Dragon True Form!"
Dugu Bo and Liu Erlong directly activated their martial souls to fight the enemy.
A forty-meter-long Golden Phosphorus Snake King with a golden dragon head and snake body rushed towards the Sky Eagle, while a twenty-meter-long fire dragon also lunged at the Sky Eagle.
The Sky Eagle fought fiercely against Dugu Bo and Liu Erlong. The impact of their clash directly repelled the surrounding bird soul beasts, while Li Luochen and Dugu Yan remained safe behind Flanders.
In the sky, the bluish-white body of the Sky Eagle was already two-thirds green from poison, and a small part was charred by flames. The Sky Eagle sensed that it had encountered a formidable opponent. It tried to flee but was entangled and couldn't escape. The poison wasn't severe, but it was enough to quickly sap its combat strength. The fire dragon next to it would deliver heavy blows from time to time, making it difficult to handle.
"Okay, Long girl, go switch with Flanders; this is almost over."
Dugu Bo transmitted a message to Liu Erlong, who flew directly to where Flanders was. After speaking with Flanders, she released her martial soul avatar, while Flanders activated his and quickly joined the battle.
During this brief substitution, the Sky Eagle seemed to seize an opportunity. Its entire body glowed with light as it took Dugu Bo's attack head-on and attempted to escape into the distance.
"Hehe, you think you can run? Eighth Soul Skill: Time Freeze!"
Dugu Bo released his eighth soul skill, freezing the Sky Eagle in its tracks.
"Flanders, quickly gather your strength and aim for the wound on its belly. Try to kill it with one strike. I'll use the Snake King's Restraint to trap it after I release the time freeze, but it will only be restrained for a few seconds. You must try to kill it with one blow."
Dugu Bo instructed Flanders and immediately began gathering soul power in his left arm.
"Got it, Your Majesty!" Flanders concentrated soul power in his right arm. This was a 50,000-year-old right arm bone that Flanders had obtained from the same soul beast as his seventh soul ring.
With powerful single-target attack capability, the Golden Eagle Sky-Splitting Claw was Flanders' strongest attack.
"Get ready! I'm about to start."
Dugu Bo signaled to Flanders, and the soul power in his left arm surged.
The time freeze was lifted, and before the Sky Eagle could react, it was entangled by several green snake shadows.
"Golden Eagle Sky-Splitting Claw!" When Flanders uses the soul skill of his right arm bone in the state of his martial soul's true body, the effect is doubled! The soul rings and soul bones from the same soul beast have complementary effects.
Flanders' martial soul incarnation has the greatest effect on the skills of his right arm soul bone.
A golden slash struck the Sky Eagle's abdominal wound. Since the abdomen was corroded by snake venom and lacked feathers for protection, Flanders' blow shattered the Sky Eagle's internal organs.
The Sky Eagle let out its final cry, lowering its proud head, and a black soul ring emerged.
