"Yes, senior! However, please swear with the heart of Taoism before I can tell you the treatment method for me with confidence." Wang Kai slowly spoke up after returning the nine-section jade to Dugu Bo, and then retracting the Youxiang Qiluo Immortal Product to the small plane.

"That's natural." Dugu Bo nodded, and then began solemnly and said, "I, Du Douluo Dugu Bo, swear with the heart of Taoism. If you can remove the toxins in my body, I will not hurt you and let you go safely. And if you can also remove the toxins in my granddaughter's body, then I will agree to your three additional requests that do not violate my principles."

He already agreed in his heart that Wang Kai was the descendant of those ancient hidden tribes. Dugu Bo had no idea of ​​killing Wang Kai. When Wang Kai made a request, he swore with the heart of Tao very neatly.

"Thank you senior!" Seeing Dugu Bo swearing, Wang Kai continued to speak: "The treatment I mentioned later may exceed your understanding of senior, but I can also swear that this method can definitely relieve the toxins in the senior's body, so please listen to my explanation patiently.

"No problem!" Dugu Bo nodded slightly: "However, I don't think the treatment you mentioned will exceed my knowledge. I have lived so old and have never encountered anything that I know. You can speak boldly."

"Thank you for your understanding!" After saying that, Wang Kai walked forward a few steps in the direction of the Binghuo Liangyi Eye, pointed his hands at the octagonal black ice grass and Liehuo Xingjiao on both sides of the Binghuo Liangyi Eye and said lightly: "The treatment I mentioned is to take these two herbs at the same time."

"These two plants?" Dugu Bo's brows furrowed together as he listened to Wang Kai's words: "These two herbs are extremely cold and the other is extremely hot. Boy, you don't want to secretly kill me by using the name of the name, right? I tell you, although I am not young, my mind is still very clear!"

Dugu Bo was quite impressed by the star anise black ice grass and the fiery apricots pointed to by Wang Kai. After all, he had personally tested these two herbs. Even with his cultivation, he could not stay by their side for too long when he heard Wang Kai's words. Dugu Bo suddenly became suspicious.

"It's not the case. Please listen to my explanation for me!" Wang Kai shook his head and then continued.

"Indeed, these two herbs are poisonous. Even if ordinary people get close to them within ten meters, they will freeze or turn into ashes in less than a few minutes, let alone eat them. However, as the saying goes, yin and yang are incompatible, and ice and fire are mutually controlled. When these two extreme herbs are put together, they will neutralize each other and their toxicity will be greatly reduced, and that is the only chance to take them."

"So that's it!" Dugu Bo nodded as he heard Wang Kai's words. He didn't know that these two herbs could be taken like this, but he continued to ask in confusion: "You kid are very knowledgeable, but what does this have to do with treating the toxins in my body?"

"Senior, don't worry! I think, since you have chosen this place as a place for cultivation, you must have felt the benefits of this unique environment to your body. I believe that you also have a personal experience. Once you enter this valley, especially when you get close to this spring, the toxins in your body will be suppressed and your body will not be tortured by pain. I'm right?" Listening to Dugu Bo's question, Wang Kai smiled and told the story.

"You are right!" Dugu Bo nodded as he listened to Wang Kai's question.

"The reason why seniors are not tortured by toxins here is precisely because of the effect of this spring. The cold Yin Spring and the hot Yang Spring in this spring have extremely strong restraint on any poison, and the spring water is even more invasive. For ordinary soul masters, they cannot tolerate the environment here at all, even powerful soul beasts, but for seniors, the breath of this spring can suppress the toxins in your body and prevent them from attacking again!" Wang Kai continued to start and said.

"Are you saying that if these two herbs are taken together, they can have similar effects?" As a titled Douluo, Dugu Bo is naturally not a stupid person. Since Wang Kai has said this, Dugu Bo has naturally guessed it.

"That's right!" Wang Kai nodded and said, "After taking it, the two toxins in the two herbs will change from mutual repulsion to complement each other, forming a unique environment similar to this spring in the body of the predecessor."

"Although the effect of this small spring is definitely not as good as the big spring here, it is better because it is in the body of the senior, and it can perfectly suppress the toxins in the senior's body. Even if the toxin is completely resolved, it can completely suppress the toxins in the senior's body so that the senior will not be harmed in the future."

"Is this true?" Dugu Bo muttered in disbelief, and then continued to ask: "But, there is only one of these two herbs. If I cure me, what should I do with my granddaughter?"

"This is simple!" Wang Kai smiled faintly and said calmly: "As long as the senior refined these two herbs, your body will naturally bring the medicinal power of these two herbs. The senior's granddaughter is still young, and the body is definitely not as good as the senior. Therefore, as long as the senior gives his blood to your granddaughter for about a year, her body can be naturally healed."

Dugu Bo frowned and thought for a while, and finally made up his mind to speak, "Okay, I believe you once! But now, please eat this first. Although my life is not worth much, I still want to live a few more years. If you cure me to death, then please let me bury you with me!"

While talking, Dugu Bo opened his mouth and a green light spit out from his mouth, it was a green bead.

Under the control of Dugu Bo Soul Power, the Luzhu slowly drifted towards Wang Kai. Wang Kai opened his right hand and let it fall into his palm.

This is the elixir bead that Dugu Bo's martial soul, the Biphosphon Snake, evolved into a elixir condensed by the Snake Queen. Half of his strength is in this elixir bead. Once it explodes in his body, even the Peerless Douluo will be seriously injured!

Faced with such a strange treatment method, this is a backup plan left by Dugu Bo.
