After scolding Liu Shenwei, Sun Simiao asked Zhang Xuanqing about the "alcohol" thing: He really likes medical skills, unlike Zhang Xuanqing, who studied medicine completely to deceive people better in the future.

Seeing that Zhang Xuanqing finally fooled the other party, he felt relieved, but then he felt a little embarrassed.

This is so embarrassing today. You have to find some face for yourself no matter what you say!

Suddenly, his heart moved slightly, and he remembered that there was an alcohol lamp in the medicine box. His eyes rolled, and he smiled and said, "Brother Sun, in fact, alcohol is extracted from wine, and it is not strange. However, this alcohol has many uses. It can not only be used to clean wounds, but also to acupuncture..." As he said that, he took out the alcohol lamp from the medicine box and even found a fuel lighter.

This fuel lighter was prepared for him to prevent him from making a fire when he went to the wilderness. It was the famous Zippo that cost Zhang Xuanqing two or three hundred dollars, which made Zhang Xuanqing feel very distressed at that time.

In the inexplicable eyes of Sun Simiao and Liu Shenwei and his disciples, Zhang Xuanqing turned on the lighter and wiped the fire, but he didn't. He wiped it again, but he didn't.

Zhang Xuanqing suddenly felt a sense of fear. God, who was not in the time and space of the Tang Dynasty, also saw that he was unhappy and wanted to play with him, right? Why do you feel more and more unlucky?

Suddenly, with a bang, the fire was burning and the lighter was finally ignited.

Zhang Xuanqing then breathed a sigh of relief and said, "God, why did Grandpa dislike him? He must have bought a fake one."

"ah!"

"ah--"

Sun Simiao and Liu Shenwei exclaimed one after another, their eyes full of horror.

Liu Shenwei stuttered: "Master...Uncle...What kind of immortal method are you?"

Zhang Xuanqing laughed in his heart, asking you to tell me, but I won’t tell you, Humph! Use a lighter to ignite the alcohol lamp, and then turn the lighter off and put it in the medicine box: "Brother Dao, Shenwei, look. The fire of this alcohol lamp can be used to burn silver needles, and will not leave burn marks on the silver needles. It is much cleaner than the oil lamp we used to use..."

Sun Simiao and Liu Shenwei's mind were still here. His eyes were staring straight into the medicine box, wanting to see the treasure that could make fire out of thin air.

If Zhang Xuanqing had not realized it, he explained to Sun Simiao and Liu Shenwei, while taking out a silver needle and baking it on the alcohol lamp.

After a long time, Liu Shenwei blew and pounced on Zhang Xuanqing's thigh: "Uncle Master, I'm sorry for you, I shouldn't believe you. You don't remember the villain's mistakes, don't bother with your disciples..."

Sun Simiao covered his face and felt very embarrassing.

After teasing Liu Shenwei for a while, Zhang Xuanqing explained the principle of the lighter to them.

In fact, fuel lighters are not very great, they are just more exquisitely designed, and the oil used inside. If you can find oil in this era, although you may not be able to make a lighter, it is also possible to use flint to ignite oil. This is also the reason why Zhang Xuanqing chose a fuel lighter to bring it.

After hearing this, Sun Simiao said, "So that's it. The oil mentioned by Brother Dao is stone fat water? I have heard someone mention it before. There is stone fat water 180 miles southeast of Yuanhe County, and the spring has moss, like fat meat, which is extremely bright. There is ink fat on the water... I think the oil mentioned by Brother Dao should be a thing."

Oil was discovered in ancient China for a long time. For example, in the Book of Changes, "There is fire in the water" means that the phenomenon of oil steam ignites on the water surface of lakes, ponds and swamps. Of course, this cannot be counted. However, according to the "Former Han Book of Han·Volume 38 2·Geographical Records 8" written by the Eastern Han Dynasty writer and historian Ban Gu, it says: "Dingyang, Gao Nu, there is water confusing, and fertilizer can be dipped." It is oil, which has a history of more than two thousand years.

However, although Sun Simiao knew the origin of oil, he was still very curious about the lighter Zhang Xuanqing took out.

Seeing this, Zhang Xuanqing simply gave the lighter to the other party.

Sun Simiao wanted to refuse, but unfortunately he accepted a shameful apprentice. After Zhang Xuanqing said that, Liu Shenwei grabbed the lighter and laughed.

At this time, the three of them still didn't know that two Taoists had arrived outside the city.

...

"Master, do you say that there are immortals in this county? Is it true or false?"

Outside Huayuan County, two Taoists stood, one forty-five and six, and the other twenty-three and four. They looked at Huayuan County from afar, and the young Taoist priests who were talking were the twenty-three and four.

Both Taoist men wore Taoist crowns and Taoist robes. The difference is that the middle-aged Taoist man held a whisk in his hand, while the young Taoist man held a sword.

When he heard the young Taoist question, the middle-aged Taoist waved his whisk and smiled: "Chunfeng, since you and I have come, go in and take a look. For my teacher, I will see the beautiful mountains and rivers of Huayuan County, and the outstanding people are outstanding. Maybe some amazing figure has really appeared."

The Taoist priest named Chunfeng nodded when he heard this, and seemed a little unrighteous in speaking. He paused and said, "Then Master, let's go."

The middle-aged Taoist priest shook his head slightly, as if he was helpless at the reaction of his disciple, and muttered: "Chunfeng, Chunfeng, how many times have you told you that you are good at everything, but you are talking too little, you must know us..."

As they spoke, the two approached the county town.

After walking straight through the city gate, the master and apprentice were about to find an inn to rest, but unexpectedly someone came to them first.

"Two Taoist priests, are you here to listen to Taoist priest Xuanqing's Dharma? You are late. At noon today, Master Xuanqing said that from today on, he will not speak again." The person who spoke was an old man, and the words "分" in his words made people feel quite awkward.

Logically speaking, this situation is usually caused by the disciple, but the middle-aged Taoist priest knew that his disciple was not good at speaking, and laughed: "I don't know what to call this brother?"

The old man waved his hand and said, "You must be polite, just call me Old Man Chen."

The middle-aged Taoist priest nodded and said, "Then call you Brother Chen. I, Yuan Tiangang, traveling around the world with my disciples. I happened to hear that an immortal appeared in Guixian the day before yesterday. I was quite curious, so I came to see it. Why, from my brother's opinion, that immortal has left?"

Yuan Tiangang? A trace of suspicion flashed across the old man's face. He always felt that he had heard of this name, but he couldn't remember it for a moment and bowed: "It turned out to be Master Yuan, the little old man's greeting." Then he shook his head and said, "But Master Yuan guessed it wrong this time. Master Zhang has not left this county yet, but he was at Zuixiang Tower at noon... No, now he should be called Zuixian Tower. At noon today, Master Zhang said in Zuixian Tower that he would be in seclusion for a period of time and would not come out to see guests during this period. Now, many Taoist priests left this afternoon, and I'm afraid that more people will leave tomorrow morning. Master Yuan, you may not know that there are not many people practicing Taoism in our Huayuan County, but since Master Zhang came, let alone Taoism priests who have been famous from other counties, even the middle-aged people in our county have added many Taoism practitioners."

"Oh?" Yuan Tiangang looked slightly curious: "Zhang Zhenren? Zuixianlou? Brother, can you tell me about the matter here? I first came, but I heard that there are immortals in this city, but I don't know why everyone is so sure?"

"It's easy to say, it's easy to say..." The old man seemed extremely talkative: "If you want to talk about Zhenren Zhang, you can't finish it even if you spend ten days and ten nights. Taoist Master Yuan, since you, the master and disciple, came for Zhenren Zhang, you must have to go to the Zuixian Tower. Why don't we talk while walking?"

"Okay, just follow Brother." Yuan Tiangang nodded with a smile.

The old man immediately led the way forward, walking back and talking about Zhang Xuanqing's affairs, such as Zuixianglou, and Zuixianglou... Well, it seems that there are only a few things that are worth talking about on Zhang Xuanqing.

However, the old man has a good memory. He not only remembers the plot of the story of the immortals who were told by Zhang Xuanqing, but also remembers the final poem that Zhang Xuanqing said. Although he only remembers it roughly, he also tells it in a very good manner and has a good reputation.

It was not until he almost arrived at the Zuixian Tower that Yuan Tiangang interrupted: "Brother Chen, after hearing that you have talked so much, it seems that that 'Zhang Zhenren' does have some real skills, but how can you determine that he is an immortal who descended to earth?"

Old Man Chen was stunned and then said happily: "This Taoist Master is unknown. If you want to talk about Zhenren Zhang, the first time he appeared in our Huayuan County, he had a childish face, and he suddenly appeared. Even the city guards had never seen him. Master, think about it, since he was not the city gate, how could he enter the city? Of course, it was from the sky! Not only that, Zhenren Zhang lived in our Huayuan County for a day, and those who saw people as he looked like him were all black hair. He immediately cut off his white hair and gave him a head of black hair. And I also heard that when Zhenren Zhang first came, because his voice was the same as the ancient sound, he could only communicate with words, but in just two days, he learned our current accent..."

These things are naturally circulated from Jishitang, and Zhang Xuanqing naturally would not be idle and talk about these things to others; Sun Simiao was mature and persistent, and would not talk about the right and wrong of others behind their backs, even if they were good words; Liu Shenwei was different, and the young man's nature was inevitably a bit of showing off, which made everyone in Huayuan County known.

After Old Man Chen was almost finished speaking, a hint of surprise flashed in Yuan Tiangang's eyes and asked again: "I wonder what happened to Zuixianlou? I heard from my brother before that this Zuixianlou was called Zuixianglou at the beginning?"

Old Man Chen laughed and said, "Master Yuan, you are asking. If you want to say that Zuixiang Tower is renamed Zuixian Tower, it is just now. Although the little old man is not the first to know, now in Huayuan County, if the little old man dares to make a promise, no one will know better than me..."

It turned out that Zuixianglou wanted to change his fate in Zuixianlou early in the morning, and even asked Zhang Xuanqing for instructions. Zhang Xuanqing had no objection, but Zuixianglou specially invited someone to write inscriptions and make plaques. It took a lot of time until today's plaques were ready. They originally planned to ask Zhang Xuanqing to cut a color, but unfortunately, Zhang Xuanqing came quickly today and left quickly. The boss of Zuixianglou didn't have time to say it, so it was hard to find him again. After all, he said he was going to retreat. In the end, he had to change the plaques by himself. However, since Zhang Xuanqing came to Huayuan County, he has only been telling about his story at their Zuixianglou. This "Zuixianlou" is worthy of his name.

If Zhang Xuanqing is really an immortal...
