Guiding Dugu Yan

"The second method is the simplest: use a Soul Bone as a poison gland to store the toxins. When the time comes, all you need to do is force the potent poison within your Martial Soul into the Soul Bone, and you can avoid being affected by Martial Soul Possession."

As he spoke, Xu Yang suddenly changed the subject, leaving Dugu Yan conflicted.

"However, to resolve the problem of toxins at the Titled Douluo level, the Soul Bone must be at least fifty thousand years old. Moreover, it must be a Limb Bone, or it won't be able to withstand the endless potent poison within a Titled Douluo's body.

And once this Soul Bone is used, it won't be able to continue being passed down through the generations like the bones of other sects.

Of course, you could also absorb four ten-thousand-year-old Limb Bones and store the toxins separately within each one. But the cost would be far too great. Very few forces could afford it."

The value of Soul Bones went without saying. At present, aside from Spirit Hall and the Clear Sky Sect, which possessed large numbers of Soul Bones, the other forces did not have many. Even the Seven Treasure Glazed Tile Sect had no more than twenty Soul Bones, most of them thousand- and ten-thousand-year-old bones. There were only three that had surpassed twenty thousand years, and they were the Seven Treasure Glazed Tile Sect's inherited Soul Bones, currently on Ning Fengzhi.

Otherwise, given the identities of the two Super Douluo known as the Sword and Bone Douluos, the Seven Treasure Glazed Tile Sect would have equipped them with a full set each. The problem was that there simply weren't any suitable ones.

Even an Upper Three Sects power like the Seven Treasure Glazed Tile Sect was in this situation, let alone a Titled Douluo without any force behind him, such as Dugu Bo. Finding a suitable Soul Bone would be even more difficult for him.

"Xu Yang, why does it have to be a Limb Bone? Can't it be a Torso Bone or a Head Soul Bone?!" Dugu Yan asked anxiously. She remembered that her grandfather had a sixty-thousand-year-old Medusa Head Bone, which perfectly met the age requirement Xu Yang had just mentioned.

"Because they can be replaced. Once the quantity of toxins exceeds the Soul Bone's limit, the Soul Bone will be damaged. If the toxins accumulated over such a long time suddenly erupted, even a Super Douluo would die on the spot. But as long as you find the right method, Limb Bones can be replaced. Head Soul Bones and Torso Bones cannot.

"Moreover, the head is where the spirit is housed. If you use a Head Soul Bone to absorb the toxins in your body, then once the Soul Bone reaches its storage limit, that Spirit Master will have no hope of making further breakthroughs. The same goes for a Torso Bone. So the best choice is still a Limb Bone."

Xu Yang explained patiently.

Dugu Yan nodded seriously. It was indeed as Xu Yang had said. A person could still live without their limbs, but without a head or torso, death was the only outcome. Limb Bones were indeed the best choice.

She planned to ask for leave and return home later to tell her grandfather about this method. Before that, however, she wanted to hear about the third method.

"What about the third method?!"

"The third method... Well, I feel it's somewhat far-fetched. It would be to use legendary Immortal Herbs to achieve Martial Soul Evolution, improving one's innate aptitude and resistance to poison. For example, the most suitable Immortal Herb for a Spirit Master with the Poison Attribute would be an earth-element Immortal Herb. After absorbing it, they would basically be free from the trouble of toxins before reaching the Titled Douluo realm. But whether such legendary existences actually exist in reality is itself a question. I searched through the records of the Seven Treasure Glazed Tile Sect and the Heaven Dou Royal Academy, and only found records of a few of them."

Xu Yang deliberately revealed a wry smile, guiding Dugu Yan toward Immortal Herbs. Dugu Yan had definitely been to the Ice and Fire Yin Yang Well and had seen what Immortal Herbs looked like. She simply didn't know their names or how to use them.

"Immortal Herbs..."

Sure enough, after hearing about the existence of Immortal Herbs, Dugu Yan unconsciously recalled the strange medicinal plants in her grandfather's herb garden. Every one of them looked extraordinary—unique and beautiful. The outside world had never seen anything like them. They should be the "Immortal Herbs" Xu Yang was talking about.

"Xu Yang, do you think Immortal Herbs really exist?!" Dugu Yan asked, pretending to be calm. She failed to notice that her voice was trembling slightly.

"They should exist. For example, I once saw a record of the Singular Velvet Sky Chrysanthemum in the Heaven Dou Library. Although I've never seen this herb in reality, I saw in the Seven Treasure Glazed Tile Sect's intelligence reports that Chrysanthemum Elder of Spirit Hall possesses a Singular Velvet Sky Chrysanthemum Martial Soul. Since it exists as a Martial Soul, it isn't impossible that the Immortal Herb itself exists as well!"

As he spoke, Xu Yang took the note recording the Singular Velvet Sky Chrysanthemum from his Storage Ring and handed it to Dugu Yan.

Dugu Yan took it and looked at it. Her Pupils immediately contracted. She had seen this herb before—in her grandfather's herb garden. Could that mean that the other plants in her grandfather's herb garden really were Immortal Herbs too?

She had still been uncertain before, but now she was utterly convinced. Those were all Immortal Herbs. If she could find records of those herbs and learn how to use them, perhaps she could solve the problems plaguing both her and her grandfather.

After searching for so many years, the solution had actually been right beside her.

"Xu Yang, thank you!"

Tears welled in the corners of Dugu Yan's eyes. Overcome with excitement, she hugged Xu Yang and planted a hard kiss on his cheek. Then she turned and ran out of the room toward Qin Ming's residence. She was going to ask for leave, find her grandfather, and confirm whether these three methods were truly effective?!

"Did I guide her a little too much?!"

Xu Yang felt slightly embarrassed. He reached up to touch the spot where she had kissed him and murmured as he watched Dugu Yan's retreating figure.

Dugu Manor was located on the outskirts of Heaven Dou City. There were very few people within a thousand-meter radius, and there were no servants inside the estate. Only Dugu Bo and Dugu Yan lived there. Normally, no one dared to provoke this Titled Douluo.

At that moment, in the main hall of Dugu Manor, Dugu Bo was leisurely drinking medicinal tea while listening to Dugu Yan recount the methods Xu Yang had mentioned.

The more he listened, the more unsettled he became. The hand holding his teacup began to tremble, and his eyes filled with shock and delight, along with a trace of regret. Why hadn't he thought of such a simple method sooner? If he had realized it earlier, perhaps his son and daughter-in-law would not have died, and Yan Yan would not have been born carrying potent poison in her body.

At first, he had thought that the Soul Bone method was already the optimal solution. But after hearing Dugu Yan mention the Immortal Herbs, he could no longer keep his expression composed. As he looked at the description of the Singular Velvet Sky Chrysanthemum in his hand, he knew it was real.

He and Yue Guan had quite a few grudges between them, so he understood the Singular Velvet Sky Chrysanthemum Martial Soul fairly well. He had even considered researching the Immortal Herb in his own garden to find a way to deal with Yue Guan. Unfortunately, he had never known how to use it, so the matter had been shelved.

Now, looking at the notes in his hand, he never would have expected the Singular Velvet Sky Chrysanthemum to possess such an effect. It truly lived up to its reputation as an Immortal Herb.

Moreover, since Yue Guan possessed the Singular Velvet Sky Chrysanthemum Martial Soul, and given his fondness for flowers, he most likely had records concerning Immortal Herbs in his possession.

No, the defenses around that strange place were still far too simple. They had to be strengthened. Once Spirit Hall discovered it, it would truly become an undeserved disaster.
