"Xiao Yu, do you still have any of those grenades?"
The Ice and Fire Yin Yang Eye.
As they prepared to take Dugu Yan to hunt the third spirit ring, Dugu Bo felt a surge of excitement and asked Ye Yu.
However, it wasn't that simple.
Creating gunpowder grenades in the Douluo Continent was far from easy.
Black gunpowder and sugar were materials Ye Yu had to create himself.
The grenade shrapnel was made from rare and expensive metals, and the shell was painstakingly crafted by one of the most skilled blacksmiths in Heaven Dou City, who had spent a great deal of time forging it.
It had taken over half a year, and Ye Yu had only created three grenades, all of which Dugu Yan had already used up.
"Grandfather, there's none left. These are really difficult to make."
"In all this time, I've only made three, and Yan Yan has already used them all."
Ye Yu smiled helplessly and shook his head.
Without the grenades, this time, it would have to be Dugu Bo himself who would help Dugu Yan hunt for a spirit ring.
After a bit of searching in the Sunset Forest, Dugu Bo helped Dugu Yan hunt down a Stone Poison King Snake with a cultivation age of over 1,500 years.
After absorbing the Stone Poison King Snake's spirit ring, Dugu Yan gained her third soul skill: Phosphorus Gray Poison!
This soul skill released a gray toxic mist capable of eroding both soul power and life force. Once the soul power and life force were completely corroded, the body would gradually petrify, turning into a stone statue!
In addition to this, Dugu Yan also possessed her first soul skill: Phosphorus Red Poison, and her second soul skill: Phosphorus Black Poison.
Phosphorus Red Poison stimulated the nervous system, temporarily enhancing the user's attack power and speed by 20%. However, as the saying goes, "Medicine is three parts poison," and the Phosphorus Red Poison was no exception. Once its effect wore off, the poisoned person would fall into a state of nervous exhaustion, with both physical constitution and energy decreasing by 40%. If not treated in time, irreversible nerve damage could occur.
However, if the person was poisoned and received treatment using Ye Lianling's Nine-Heart Begonia martial soul's life force, it could counteract the negative effects.
As for the second soul skill, Phosphorus Black Poison, it released highly corrosive black poison liquid or slightly less powerful black poisonous mist. Its corrosive ability was so strong that it could even erode stone, making it a formidable weapon.
After helping Dugu Yan obtain her third spirit ring, Dugu Bo once again took Ye Yu and Dugu Yan back to the Ice and Fire Yin Yang Eye.
"Xiao Yu, are you sure you're going to consume these two Immortal Herbs?" Dugu Bo asked, seeing Ye Yu preparing to take the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot to further strengthen his Blue Silver Spirit Jade Vine martial soul.
Though Dugu Bo had already known Ye Yu planned to take these two herbs to enhance his martial soul, seeing him take out his jade knife and jade box and carefully picking the herbs, he couldn't help but ask again.
"I'm sure!" Ye Yu replied with a smile, nodding seriously.
"Don't worry, Grandpa, it will be fine." Ye Yu reassured Dugu Bo. "As long as I follow the method in the ancient book and take both Immortal Herbs together, nothing will go wrong."
"On the contrary, they'll refine my body and strengthen my martial soul!"
"To become stronger, I need to take risks, but I'm confident!"
In the past, Ye Yu had touched both the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot out of curiosity and had suffered some setbacks. He knew firsthand that they were dangerous.
Honestly, Dugu Bo still had concerns, but seeing Ye Yu's determination, he sighed helplessly and agreed.
With Dugu Bo and Dugu Yan watching anxiously, Ye Yu approached the Ice and Fire Yin Yang Eye.
After preparing, Ye Yu stood at the edge of the Ice and Fire Yin Yang Eye. Using his soul power, he took one piece of Octagonal Mysterious Ice Grass and Infernal Delicate Apricot and put them into his mouth, swallowing them together.
In an instant, Ye Yu felt waves of icy cold and intense heat alternately surge from his abdomen, quickly circulating throughout his body, causing immense pain.
For a while, he felt as though he were in a freezing world, almost like his body was about to shatter from the cold.
Then, he felt as though he were immersed in magma, his body feeling as though it might burn up and melt.
Under the watchful eyes of Dugu Bo and Dugu Yan, Ye Yu's face contorted in agony, his body constantly changing color, alternating between ice-blue and fire-red, with ice crystals forming on his body and scorching hot steam rising.
Despite the pain, Ye Yu gritted his teeth and endured. Once he felt the medicinal effects kicking in, he jumped into the center of the Ice and Fire Yin Yang Eye.
"Plop!"
A splash echoed, and as Ye Yu sank into the water, the intense cold and heat caused him to lose consciousness. But his body continued to be tempered in the alternating ice and fire.
Meanwhile, the potent medicinal powers of the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot reacted with the distinct ice and fire energy of the Ice and Fire Yin Yang Eye, transforming into pure spiritual energy that nourished Ye Yu's body.
"Is he alright?"
"It seems that consuming the two Immortal Herbs together and using the Ice and Fire Yin Yang Eye to refine the medicinal power is indeed effective!" Dugu Bo let out a sigh of relief after seeing that Ye Yu did not experience any problems.
After sending Dugu Yan back, Dugu Bo once again returned to the Ice and Fire Yin Yang Eye, watching over Ye Yu, who was continuing his body tempering process.
Though he had initially opposed Ye Yu and Dugu Yan being together, it had been out of concern for his granddaughter's future. He didn't regret that decision, and now that he had accepted Ye Yu, he truly saw him as a potential son-in-law.
Time passed quickly, and after nearly a year, Ye Yu had successfully consumed all of the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot, completing his Ice and Fire Body Tempering process.
Ye Yu climbed out of the Ice and Fire Yin Yang Eye, put on his clothes, and heard the sound of footsteps. Dugu Bo, who had been cultivating in a cave not far away, emerged and took out some prepared food from his storage soul guide.
"How are you? Would you like something to eat?"
"Thank you, Grandpa!" Ye Yu said, feeling a warmth in his heart. He gratefully ate the food, then took another dose of Octagonal Mysterious Ice Grass and Infernal Delicate Apricot before jumping back into the Ice and Fire Yin Yang Eye to continue his body tempering.
A year passed, and after completing his body tempering, Ye Yu once again stood at the edge of the Ice and Fire Yin Yang Eye, took a deep breath, and summoned his Blue Silver Spirit Jade Vine martial soul.
In a flash of silver-blue light, a vine that resembled blue crystal, with golden veins running through it, appeared before him. The main stem split into multiple branches, which spread out and draped down.
After completing the Ice and Fire Body Tempering, the Blue Silver Spirit Jade Vine had undergone significant changes. Not only had its diameter grown thicker, but red and ice-blue markings had appeared on the vine.
