In front of the sand dune, he stayed for a long time, and the team did not dare to stop or stride, and all the people were moving in small steps, and no one dared to come forward to disturb him.

Qingqing knew that Thorn Duo was just immersed in her memories of the past and couldn't extricate herself, she just silently accompanied him without making a sound.

Thorn Duobu's face was solemn, his brows were furrowed, his eyes looked into the distance and his gaze was not focused, and after a long time, he let out a long breath and said softly: "Keep walking." ”

The team continued to set off, Qingqing did not return to Yin Jiangzi's side, but accompanied Thorn Duo Buti to ride a horse and followed the front of the team, along the way, Thorn Duo Bu Ti and Qing Qing introduced the places and plants they saw, and there were many stories that were circulated, and Qing Qing listened to it with relish.

What Qingqing admires most about Thorn Duo is that he was still sad and sad because of the sad past that he couldn't change just now, but after leaving that place, he quickly adjusted his emotions. This is a will that must be honed by people who do great things, and only those who can control their emotions can control their lives well.

After three days, Qingqing found that her breathing was becoming more and more difficult, she suddenly remembered if it was the reason for the higher and higher altitude, she was afraid that the original people among them would not be able to adapt, so she rode a horse to see them, and found that it seemed that she was the only one who reacted, and everyone else quickly adapted to such an environment.

Qing Qing embarrassed and returned to the side of Thorn Duobu, although the place where he was walking now seemed to be flat, but the altitude had reached more than three thousand meters.

Thorn Duo didn't mention looking at Qingqing and noticed that her face was a little abnormally red, knowing that she might be suffering from altitude sickness, so he ordered someone to send a bowl of soup medicine to Qingqing.

Qingqing looked at the bowl of black and sedimentary potion, and looked at the thorn Duo Bumen's eyes full of rejection.

"Child, this medicine can help you adapt to the climate and environment here faster, otherwise it will get higher and higher in the future, you will be dizzy because you can't breathe, and the most serious thing is that you will bleed to death." Thorn Duo didn't mention that he was just calmly narrating, of course Qingqing knew this, because she had learned about altitude sickness in geography class before, but the book said that she should take oxygen instead of drinking this terrifying potion.

However, Qingqing still took the medicine bowl and drank it dry, the bitter potion slowly slid down his throat, and a trace of coolness slowly spread from his throat to his whole body, and Qingqing felt that his chest was not so stuffy.

After waiting for a while, Qingqing felt that her whole body was much more relaxed, and she looked at Thorn Duo in surprise: "Father-in-law, I feel much better, this medicine is really magical, what kind of herbs are used to make it?" I'm going to ask my master to study it and see if I can get more finished products. ”

Thorn Duo didn't mention a faint smile, and pointed to the ground outside with his finger: "Many of the medicinal herbs in the potion you drink are treasures grown in that land, but ordinary people can't find them, so your bowl of medicine is no less precious than a thousand horses." ”

Hearing that Thorn Duo didn't mention this, Qingqing looked down at the black scum left in the bowl, is it so valuable? She didn't even feel like she was bluffing her, so she made an excuse to take the bowl and go to Yin Jiangzi again.

She just wants to figure out what these things are, how can they be better than direct oxygen inhalation, of course, in this era, it is almost impossible to want pure itching, and there is no technology to refine. Therefore, she was even more curious about the ingredients of this potion.
