The four of them went all the way back to the house, and Li Chunfeng also asked for the basic information of this Hu woman.

The Hu woman's surname is Mi Mingxue, the old father Miller Shen, the ancestor of the family was originally a Yueshi person, the Han Dynasty was forced by the Xiongnu, the west exceeded the green mountains, and later lived in the foothills of the Qilian Mountains, but since the Qilian Mountains were controlled by the Turks, the people living there are becoming more and more difficult day by day.

Walking on the road, Michelle was a little depressed, and recalled: "The Turkic Jieli Khan ascended the throne, in order to develop the army, the Sogdians, the Yue people and other ethnic groups were expropriated, our family because they could not pay, was convicted by the Turks and sent into servitude, one day, my father and I saw that the Turks were unguarded, and fled at night, but my mother fell ill on the way out, and died not long after." ”

"Mi Niangzi's Day mourns and changes." Li Chunfeng frowned, why is this title so weird to shout?

Mi Xue was also aware of this problem and said, "If Li Lang doesn't dislike it, you can call me Xiaoxue." ”

Li Chunfeng nodded, the name "Xiaoxue" was much more pleasant.

"By the way, let me take the liberty of asking, what is the name of the instrument that Ling Zun and you used just now? It looks quite strange, but it's the first time I've seen it. ”

Mi Xue smiled slightly and said, "The one in my father's hand is called Xi Qin." ”

"Xi Qin?" Li Chunfeng nodded and pointed to Mi Xue's hand, "This is Xiao?" ”

Michelle shook her head slightly and said, "This is called shakuhachi in our place." ”

"Shakuhachi?"

"The pipe is one foot eight inches long, hence the name."

"Oh, I see."

After listening to Mi Xue's introduction, Li Chunfeng said secretly: "Maybe it's just that there are some differences between the names of today and ancient times." ”

As they spoke, the three of them had already come to the front of the mansion under the guidance of Li Chunfeng.

"Wow, Li Lang, your family is really magnificent." Li Daniu looked at the high-walled compound in front of him and sighed.

Li Chunfeng smiled slightly: "We are just temporarily living here, the house is not mine, the three of you come with me." ”

From going out early in the morning to returning home in the afternoon, Li Chunfeng didn't see anyone for most of the day, and he played "missing" without saying a word, which made the rest of the people anxious all morning.

Li Chunfeng walked into the courtyard, and as soon as he stood still, a woman's voice came: "Do you still know how to come back?!" ”

A woman who can speak so "strongly", who else can there be in this house besides Huo Xiaoyu?

Twisting his face, Li Chunfeng found that Huo Xiaoyu was standing not far away with his waist pinched, looking at Li Chunfeng, his eyes seemed to be on fire.

Li Chunfeng also knew that he was at a loss, so he smiled and said, "Yu Niang, have you had lunch?" ”

"Lunch?" Huo Xiaoyu said angrily, "There is one less big living person in the family, how can you still have the heart to eat?" ”

"Uh......" Li Chunfeng scratched his head and said, "I was really anxious to go out in the morning, I didn't have anything to say, but this world is peaceful, so you don't have to worry so much, right?" ”

"Worried? Who's worried about you anymore! Huo Xiaoyu muttered, turned his head to look at Li Daniu and the others, "Who are these?" ”

Li Chunfeng said: "These are all my friends." ”

"Friends?"

While speaking, Yuan Tiangang and Sun Simiao also heard the movement and walked out of the house.

"Li Lang is back?" Sun Simiao smiled and said, "I said there will be no problem, Yu Niang, I believe in old decay now, right?" ”

"Where he goes, what does it have to do with me." Yu Niang's face was slightly red, and her gaze was a little evasive.

Sun Simiao smiled: "Yo? I don't know who has been idle all morning. ”

"Humph! ~" Huo Xiaoyu glanced at Sun Simiao fiercely, turned around and left with a red face.

Yuan Tiangang looked at the Mi father and daughter and said, "Who are the three of you?" ”

Mi Xue bowed her body to give a salute: "Concubine Mi Xue, this is the father of the family, Miller Shen, who was fortunate to be rescued by Li Lang on the street today, so that my father and daughter escaped prison." ”

"Chunfeng, what's going on?" After not seeing him for a morning, Li Chunfeng led the two Hu people back home, and Yuan Tiangang couldn't help frowning slightly.

Li Chunfeng said: "Master, that's the case, today, I wanted to walk around Chang'an City, but I didn't expect to meet this little Taoist, the two of us hit it off at first sight, and then we went out of the city to the Taoist temple of the small Taoist." ”

"That's right." Da Niu nodded.

"Then, when I returned to the city, I met the two of them being interrogated by Jin Wuwei," Li Chunfeng said, "I saw that they were penniless and homeless, so I temporarily invited them to stay at home." ”

"Stay?" Yuan Tiangang was stunned.

Michelle bowed again: "I'm sorry for the interruption." ”

Li Chunfeng said: "Master, don't worry, they will leave when they settle down." ”

"Well, since it's your friend, there's no reason to object to it," Li Chunfeng said, "But a reminder for the teacher, in this Chang'an City, it's best not to wear Hu people's clothes, it's too eye-catching." ”

The early Tang Dynasty was not as open as later generations, so the Hu people were still very noticeable in Chang'an City.

Li Chunfeng nodded: "Master, don't worry, they will change their clothes." ”

"yes, okay." Yuan Tiangang's gaze moved to Li Daniu and said, "This little Taoist leader, where do you practice?" ”

"White Deer View in the east of the city." Da Niu laughed.

"Poor Yuan Tiangang."

"Wow, I didn't expect that your master and apprentice are also cultivators," Li Daniu suddenly realized, looked at Li Chunfeng and said, "No wonder you know the art of alchemy, it turns out to be a Taoist friend." ”

"A little bit of understanding, a little understanding." Li Chunfeng replied matter-of-factly.

"Daochang Li is humble."

"I'm telling the truth."

“……”

Sun Simiao on the side opened his mouth and said, "Alchemy? Li Lang, did you go to Bailuguan Alchemy? ”

Li Chunfeng touched his head: "It's not alchemy, it's just to verify the conjecture in my heart." ”

"Daochang Li is amazing, he turned water into ice with saltpeter!" Li Daniu was afraid that the world would not be chaotic, so he brought out Li Chun's old bottom and discernment.

Li Chunfeng originally intended to hide it from Yuan Tiangang and Sun Simiao, but now that he has been stirred up by Li Daniu like this, it seems that he can't hide it.

"Saltpeter? Ice refining? ”

Li Chunfeng couldn't hide it, so he could only say: "Last night I accidentally beat saltpeter into the water and found some Xiaoice crystals on the wooden basin, so I wondered if these ice crystals were related to saltpeter, and this morning, I verified it at Bailuguan." ”

Sun Simiao was stunned for a moment, a little surprised: "What is the result?" ”

Li Chunfeng said: "The first time it only condensed a thin layer of ice, and the second time it was a complete success. ”

"Can saltpeter really make ice?" Sun Simiao stroked his beard, "Amazing, wonderful!" ”

Li Chunfeng didn't explain the principle to Sun Simiao, but said: "Sun Weng, you say, if we use saltpeter to make ice and then sell it, what about it?" ”

"Selling ice?" Sun Simiao was stunned for a moment and looked at Yuan Tiangang, "Daochang Yuan, what do you think?" ”

"This ......" Yuan Tiangang also had no experience in being a trader, and said vaguely, "It's hard to say......"
