Tang Xi didn't actually leave, and after going out, he hid in a place where the two couldn't see.

As soon as she took out the seeds of the Ning Shen Grass, she heard the conversation between the two in the house.

King Anyang wants the secret recipe of the spiritual spring?

Tang Xi smiled indifferently, if this could be made with a secret recipe, she could sell it to them and make a lot of money, but unfortunately, she couldn't.

Tang Xi regained his mood, put his steps heavier and walked in, Imperial Physician Zhang and Imperial Physician Wang hurriedly stopped communicating after hearing the footsteps, and the two looked at each other at the same time.

Imperial Doctor Zhang smiled and said, "The little divine doctor is back." ”

Tang Xi smiled and said: "Na, this is a seed, I have so much generality, you have to be careful when you look at it, after all, a seed is also very precious." ”

"Definitely, definitely!"

Imperial Physician Zhang smiled and took the palm-sized small cloth bag, opened it carefully, and then held it with his hand to see the seeds inside.

The seeds are all small grains, similar in shape to cabbage seeds, but like super-small soybeans, and they also have a faint aroma.

The two stared at it for a long time and couldn't remember where they had seen such herbal seeds.

"That, little miracle doctor, can you sell us this seed?" Doctor Zhang asked.

"I'm afraid it won't work." Tang Xi's face was puzzled: "After the master passed away, he only left this little bit for you, what should I do?" ”

"Then what do you think of this," Dr. Zhang said, "Let's buy a little and keep a little for you?" ”

"This ......"

Tang Xi groaned: "I'm afraid you won't be able to grow it." ”

"What do you mean?" Imperial Physician Wang frowned, "Although our medical skills are not as good as yours, we have been doctors for decades, and we have also maintained a lot of precious herbs, so why can't we grow them?" ”

It's a bit of a shame, but it's also true.

Tang Xi said in a serious tone: "It's not a secret, this herb, ordinary soil, it can't grow. ”

She has tried this Ning Shen Grass, and like the Ten Thousand Spirit Flowers, it needs to be irrigated by the spiritual spring in the space to grow, and the conditions are very tricky.

Doctor Wang disagreed, "Isn't it okay to choose fertile soil for planting?" ”

"I'm afraid Imperial Physician Wang doesn't understand what I mean." Tang Xi said with a smile: "After this Ningshen grass is planted, it needs to be watered with special potion leaves to grow, otherwise, it will not grow." ”

"A special potion?" Imperial Physician Zhang was curious, "What kind of liquid medicine do you need, is there a secret recipe?" ”

Tang Xi kindly reminded: "Naturally, I gave the county lord Hanrong the kind of medicinal liquid. ”

"What?"

The two imperial doctors Zhang Wang were shocked.

"You take the liquid that cures your heart and sprinkle the herbs? You, you, you're a terrible thing! Doctor Wang was so angry that his old face turned red.

"I can't help it." Tang Xi said helplessly: "I don't want to, but you can't just treat heart disease and insomnia, you must know that many diseases are caused by lack of sleep." ”

Imperial Physician Wang: ......

He couldn't refute it, because the little girl had some truth in what she said.

"In this way, we don't want any secret recipe," said the imperial doctor, "You can sell a small bottle of the liquid medicine to the old man, and the price is as you like." ”

"Do you think that my liquid medicine is cabbage?" Tang Xi sighed lightly, shook his head and said helplessly: "Do you know, how long did it take me to refine the bottle in the county lord's hand?" ”

"For how long?" Doctor Wang frowned and asked.

Tang Ximian said nonsense without changing his face: "That is what I spent nearly half a year to refine, and I also used a lot of precious medicinal materials, if it weren't for the face of City Lord Xie, I wouldn't be willing to give it, you can buy it now, and you don't ask me if I have it." ”
