The next day, under Dugu Bo's personal guidance, Yu Tianheng and Dugu Yan left the villa located near the Ice and Fire Yin Yang Well and headed to the core of Sunset Forest to hunt suitable Soul Beast and obtain the required Soul Ring.
Yu Tianheng possesses the Blue Lightning Tyrant Dragon Martial Soul. This Martial Soul requires obtaining Soul Ring through a sub-dragon Soul Beast in order to unleash Martial Soul maximum power.
Dugu Yan possesses the Jade Phosphorous Serpent Martial Soul, and the Soul Ring suitable for her can come from a variety of Soul Beast, giving her a wider range of choices than Yu Tianheng.
By asking Dugu Bo, Yu Tianheng learned which Soul Beast were suitable for Dugu Yan to choose.
The most suitable snake-type Soul Beast to choose from are the Mandala Snake and Medusa. They share the same origin as the Jade Phosphorous Serpent Martial Soul, allowing Dugu Yan to better absorb Soul Ring, enhance the Martial Soul's abilities, and increase the power of the Jade Phosphorous Serpent Poison's venom.
Secondly, there are poison-attribute Soul Beast: such as the Man Faced Demon Spider, whose spider webs are infused with neurotoxic toxins. After Jade Phosphorous Serpent Soul Master absorbs the Man Faced Demon Spider's Soul Ring, the two toxins can fuse, evolving into new toxins or enhancing the lethality of the Jade Phosphorous Serpent Poison's venom. It can also grant the Jade Phosphorous Serpent Martial Soul the powerful control provided by the spider web.
Finally, there are dragon-type Soul Beast or snake-type Soul Beast with dragon bloodlines: Dugu Bo believes that the Soul Ring of dragon-type Soul Beast or snake-type Soul Beast with dragon bloodlines can enable the Jade Ling Snake's Martial Soul to evolve, greatly increasing the probability of Martial Soul Evolution and the strength of Soul Skill.
Back then, Dugu Bo was lucky enough to kill a Soul Beast with dragon blood. After absorbing the Soul Ring of that Soul Beast, his Martial Soul evolved from the original Jade Phosphorus Snake to the Jade Phosphor Serpent Emperor.
It is worth mentioning that although Dugu Yan inherited Dugu Bo's Martial Soul, it was only the Jade Phosphorus Snake Martial Soul, not the Jade Phosphor Serpent Emperor Martial Soul.
The Jade Phosphorus Snake Martial Soul is just an ordinary snake-type Martial Soul, relatively ordinary in terms of Martial Soul and strength, and its owners are mostly mid-to-low-level Soul Master.
The Martial Soul only possesses some basic poison-attribute skills, such as spraying venom and paralyzing enemies; the power and range of these skills are relatively limited.
The Jade Phosphor Serpent Emperor is the evolved form of the Jade Phosphorus Snake Martial Soul. It is one of the top-tier Martial Soul, comparable to the Blue Lightning Tyrant Dragon Martial Soul. It possesses powerful toxicity and attack power, representing the pinnacle of poison-attribute Martial Soul. Only a very few exceptionally talented Soul Master can cultivate the Jade Phosphorus Snake Martial Soul to the level of the Jade Phosphor Serpent Emperor.
Not only does it possess more powerful poison-attribute skills, such as group poisoning and dual cultivation of poison and control, but it can also condense the Jade Phosphor Serpent Emperor Elixir Pearl to release even more terrifying poison attacks. It can even change the environment within a certain range, causing enemies to fall into a poisoned state.
Furthermore, the two Martial Soul also differ in appearance. The Jade Phosphorus Snake Martial Soul usually takes the form of an ordinary snake, with its body covered in emerald green scales, and its size is generally not large.
The Jade Phosphor Serpent Emperor Martial Soul resembles a giant dragon, with a huge and slender body, scales that shimmer with golden light, and horns that grow from its head, making it appear even more majestic and powerful.
It has already transformed into a dragon-like state.
If Dugu Yan wants to cultivate into Titled Douluo in the future, her Martial Soul of just the Jade Phosphorus Snake is far from enough. She must find a way to evolve her Martial Soul.
But it's too early to say anything about that now.
Deep in the Sunset Forest, Dugu Bo walked at the front, stroking his beard. The emerald green poisonous mist condensed into thin chains at his fingertips. As he swept away the thorns blocking his path, even the leaves were tinged with eerie black spots.
Behind him followed Dugu Yan, and then Yu Tianheng.
Dugu Bo was responsible for clearing the way ahead and blocking any dangers that might arise. Yu Tianheng was responsible for defending against dangers from behind. With his strength, he could easily deal with even Ten-Thousand-Year Soul Beast, but Dugu Yan, whose cultivation had just broken through to level 40, would be in trouble. Therefore, he was placed in the middle and only needed to move forward.
Having lived in Sunset Forest for many years, Dugu Bo was very familiar with the general distribution areas of various Soul Beast. When he learned that Yu Tianheng needed a sub-dragon Soul Beast for his Fifth Soul Ring, Dugu Bo immediately thought of a Crocodile Dragon clan not far from Biefu.
The Crocodile Dragon possesses dragon blood and can be considered a sub-dragon Soul Beast, perfectly matching the type of Soul Ring Yu Tianheng needs.
Therefore, Dugu Bo immediately informed Yu Tianheng of the situation.
Upon hearing this, Yu Tianheng said he could go and take a look.
So Dugu Bo and his group went first to the underground river where the Crocodile Dragon lived.
After walking for most of the day, the three arrived at the entrance to the underground river area.
After carefully instructing the two to be careful, Dugu Bo took the lead and stepped into the underground river.
Head towards the central area.
After walking for half an hour, the three arrived at the central area of the underground river.
"We're here, this is it." Dugu Bo pointed to a spot not far ahead.
Following the direction Dugu Bo pointed, Yu Tianheng saw that beneath the dome deep in the dark river, fluorescent moss had dyed the rock walls a dark blue curtain, while the shadowy figures swirling beneath the water's surface resembled spilled ink—hundreds of Crocodile Dragon, head to tail, their amber pupils forming a flowing, menacing light in the shimmering water.
Most of the Crocodile Dragon Crocodile Dragon in this clan have a cultivation level of over a thousand years, making them Thousand-Year Soul Beast, and many even possess a cultivation level of several thousand years.
They should not be underestimated.
These Crocodile Dragon have serrated bony spines on their backs, and dark golden mucus seeps from the gaps in their scales. When they whip their tails, the water surface bursts with silvery-white foam, and the stalactites on the rock walls are cracked like spider webs when the tail tip sweeps across them.
On the deeper stone platform, three Crocodile Dragon, each the size of a barge, were coiled up like a small mountain. Their scales were iron-black, each inlaid with fluorescent stones, and the ripples in the water with their breath carried the pressure of Ten-Thousand-Year Soul Beast —the forepaws of the left dragon were hissing with blue smoke, while the right Crocodile Dragon was exhaling icy blue mist from its nostrils, which condensed into thorny ice spikes on the water surface upon contact with that mist.
The leader of the Crocodile Dragon Crocodile Dragon, a creature twenty meters long, had a diamond-shaped crest on its forehead that gleamed like blood jade, and was surrounded by a faint purple-gold halo. When its eyelids opened and closed, its pupils reflected the ferocity accumulated over the years. Its tail swept across the black iron vein at the bottom of the water, crushing a boulder the size of a small mountain into dust.
As the deep roar of the Crocodile Dragon leader echoed through the cave, all the Crocodile Dragon simultaneously turned their heads in the same direction. The sound of their scales rubbing together was like ten thousand blades being drawn from their sheaths. The surface of the underground river suddenly surged and boiled. The Crocodile Dragon that had been lurking in the crevices of rocks and under the driftwood burst out of the water. The roars of the Thousand-Year Soul Beast and the roars of the Ten-Thousand-Year Soul Beast intertwined, turning the entire underground river into a purgatory shimmering with scales.
Dugu Bo looked at Yu Tianheng and pointed to the two Crocodile Dragon next to the Crocodile Dragon: "These two reptiles are both ten-thousand-year-old Soul Beast. The one on the left is about twelve thousand years old, while the one on the right is about twenty thousand years old."
" Tian Heng, which one are you planning to choose as your Fifth Soul Ring?"
