"Yes, sir! However, please swear with your heart first, and then I dare to tell you the cure for the elder with confidence." Wang Kai said slowly after returning the nine section jade to Dugu Bo and taking back the fragrant qiluo immortal product.

"That''s nature." Dugu Bo nodded and immediately said solemnly, "I, poison Douluo Dugu Bo, swear with my heart that if you can remove the toxin in my body, I won''t hurt you and let you go safely. If you can also remove the toxin in my granddaughter''s body, I will promise you three additional requests that don''t violate my principles."

Dugu Bo had already accepted that Wang Kai was the descendant of those ancient clans. Dugu Bo had no idea of killing Wang Kai. Seeing Wang Kai''s request, he swore with a clear heart.

"Thank you, master!" seeing Dugu Bo''s oath, Wang Kai also continued to say: "the treatment I said later may exceed your understanding, but I can also swear that this method can definitely relieve the toxin in your body, so please listen to me patiently.

"No problem!" Dugu Bo nodded slightly, "but I don''t think your treatment will exceed my understanding. I''m so old that I haven''t met anything more than I know. You can rest assured and speak boldly."

"Thank you for your understanding!" after that, Wang Kai took a few steps in the direction of the ice and fire Liangyi eyes, pointed to the octagonal black ice grass and fire apricot on both sides of the ice and fire Liangyi eyes with both hands, and said faintly: "the treatment I said is to take these two herbs at the same time."

"These two?" hearing Wang Kai''s words, Dugu Bo''s eyebrows suddenly twisted together: "one of these two herbs is extremely cold and the other is extremely hot. Boy, you don''t want to kill me secretly in the name of treatment value? I can tell you, although I''m not young, my mind is still very clear!"

Dugu Bo was very impressed by the octagonal black ice grass and the hot fire apricot pointed by Wang Kai. After all, he had personally tested these two herbs. Even with his cultivation, he could not stay with them for long. Therefore, Dugu Bo suddenly had a strong feeling when he heard Wang Kai''s words Doubt.

"No, please listen to my explanation!" Wang Kai shook his head and immediately continued.

"Indeed, these two kinds of herbs are absolutely poisonous. Even if ordinary people are within ten meters of them, they will freeze or turn into ashes in less than a few minutes, let alone eat them. However, as the so-called Yin and Yang overcome each other, ice and fire interact. When these two extreme herbs are put together, they will neutralize each other and greatly reduce their toxicity, and that is the only chance to take them."

"I see!" hearing Wang Kai''s words, Dugu Bo also nodded. He didn''t know that these two herbs could be taken in this way, but he continued to ask: "your boy is well-informed, but what does it have to do with treating the poison in my body?"

"Don''t worry, master! I think since you chose this place as a place for latent cultivation, you must have felt the benefits of this unique environment to your body. I think you also have personal experience. Once you enter this valley, especially when you are close to this spring, the toxins in your body will be suppressed and your body will not suffer pain. Am I right?" Listening to Dugu Bo''s question, Wang Kai smiled and talked about it.

"You''re right!" hearing Wang Kai''s question, Dugu Bo nodded.

"The reason why you won''t be tortured by toxins here is precisely because of the function of the spring. The cold extreme Yin spring and the hot yang spring in the spring have strong restraint against any poisons, and the poison in the spring is inviolable. For ordinary soul masters, they can''t tolerate the environment here, even powerful soul animals, but for you, the spring The breath of the eyes can suppress the toxins in your body and make them no longer attack! "Wang Kai continued at the beginning.

"Do you mean that if these two herbs are taken together, they can have a similar effect?" as a title Douluo, Dugu Bo is not a fool. Since Wang Kai has said this, Dugu Bo has guessed seven or eight times.

"That''s right!" Wang Kai nodded and said, "after taking, the two toxins of ice and fire in these two herbs will become complementary from mutual exclusion, forming a unique environment similar to this spring in the body of our predecessors."

"Although the effect of this Koizumi eye is certainly better than that of the big spring here, it is better because it is in the body of the elder. It can perfectly suppress the toxin in the elder''s body. Even if you don''t completely dissolve the toxin, you can also completely suppress the toxin in the elder''s body, so that the elder won''t be harmed in the future."

"Is that right?" Dugu Bo muttered a little incredulously, and immediately continued to ask, "but if these two herbs have cured me, what will my granddaughter do?"

"This is simple!" Wang Kai said calmly with a faint smile: "As long as you refine these two herbs, your body will naturally take the power of these two herbs. Your granddaughter is still young, and her body is certainly not as damaged by toxins as your granddaughter. Therefore, as long as you give your granddaughter your blood for about a year, her body will naturally be cured."

Dugu Bo frowned and thought for a while, and finally made up his mind to say, "OK, I believe you once! But now please eat this first. Although my old life is worthless, I want to live a few more years. If you kill me, please bury me!"

As he spoke, Dugu Bo opened his mouth and a green light came out of his mouth. It was a green bead.

Under the control of Dugu Bo''s soul power, Lvzhu slowly drifted to Wang Kai, who opened his right hand and let it fall into the palm of his hand.

This is Dugu Bo''s spirit, the blue phosphorus snake, which evolved into a pill condensed by the snake queen. Half of his strength is in this pill. Once it explodes in his body, I''m afraid even the peerless Douluo will be seriously injured!

In the face of such a strange treatment, this is Dugu Bo''s backhand.

"Naturally, there is no problem!" without any hesitation, Wang Kai threw the Danzhu into his mouth and swallowed it. However, his heart was laughing to himself - for himself with a small face, Dugu Bo''s operation that he thought was safe was just a laugh.
