Yin Jiangzi looked at the medicine residue in the medicine bowl sent by Qingqing, and couldn't help but fall into deep thought, she looked at Qingqing and stopped talking.

"What's the matter, Master? Any questions? Qingqing looked at her and guessed that there might be something unpleasant to say.

Yin Jiangzi shook her head, dipped her fingers in some medicine residue and licked it lightly in her mouth, and then licked it again, her brows began to wrinkle, Qingqing saw that she was more sure that there was something wrong with her, but this time she didn't make a sound, she waited for Yin Jiangzi to speak.

"Qing'er, these medicinal materials are all very precious materials, there is no problem." Yin Jiangzi looked up and saw clearly.

Qingqing looked at Yin Jiangzi and didn't speak, her expression just now was clear and clear, obviously she frowned and her expression was dignified, why didn't she tell the truth and just say that the medicinal herbs were okay?

Could it be that Yin Jiangzi still has any scruples?

"Master, do you have any scruples that you can't say?" Qingqing felt that the master and apprentice had lived and died together for so long, and there was nothing to scruple about.

"Qing'er, do you know your stepfather well? And do you trust him? Yin Jiangzi thought for a while and did not answer the question directly, but asked Qingqing rhetorically.

"Huh? Why do you ask? Qingqing looked at Yin Jiangzi puzzled.

"I can't see the problem from this medicine alone, I found the problem from the water in which the medicine is boiled. I remember my grandfather used to say that the environment of water determines the quality and taste of water.

Mountain spring water, underground water, plateau snow water, plain river water, etc. are all different, and different water boiling herbs will affect the exertion of medicinal properties. Yin Jiangzi's words were very professional, and I felt like I was back in geography class.

"Master, does this have anything to do with my stepfather?" Qingqing added weakly.

"The point is that your medicinal use this night is plateau snow water, as far as I know, the gathering place of the Semu people we are going to is the grassland, and now we have appeared on the plateau, which means that your stepfather did not tell you the truth and deceived us to the plateau, what are you going to do?" Yin Jiangzi looked at Qingqing's eyes with questioning and sympathy.

Qingqing thought for a moment, when Thorn Duo didn't mention that he was going to attack the Semu people on the sand table, the terrain did show flat land, and she remembered that the plateau seemed to be a place where Tibetans gathered next to it.

Speaking of Tibetans, Qing Qing vaguely seems to remember what they have learned in geography and history classes, they live on the plateau, the men are all strong and good at riding and shooting, and the women are good at singing and dancing and brave.

Qingqing bit his finger and thought for a while, then looked at Yin Jiangzi: "Master, what do you say I should do?" Shall I go and ask my father-in-law? Or do you not know what to do and move on? ”

"Do you know what's up ahead? If you are lucky enough to win, it is good to have a few casualties at most, and if you are unlucky, it will not be good to rush over after a long journey and then encounter someone else's ambush. "Yin Jiangzi has followed Qingqing and Li Haoyang for so long, and he has also learned to analyze the battle situation.

"I understand Master, I'm going to ask my stepfather, hoping that he can stop the precipice." Qingqing said as he took the bowl with the dregs of medicine and hurriedly dared to go back to find the thorns, not to mention it.

Sitting in a simple tent, Thorn Duobuti was holding a cowhide map and carefully studying the route, and his concentration did not match the usual majestic and indifferent sweat at all.

"Father-in-law, I want to ask you, are we on the wrong track?" Qingqing hesitated outside for a while, plucked up the courage to go in, and asked if he wanted to mention it.
