The doctor pulled Lu Zhe and quickly walked up to the house on the back of the flying beast, this house is not very big, but it is two-storey, the whole house is made of the strongest cedar wood, probably to resist the wind pressure caused by high-speed flight, the whole house is wrapped in iron sheets, leaving only a door and a few windows.

Walking into the house, Lu Zhe looked around at the structure of the house, it was indeed two floors, and below it was probably a place like a living room, with a table and a few chairs, and a staircase that was not wide connected to the second floor, Lu Zhe walked up, and there were two beds on it, which seemed to be a place to rest.

Suddenly, Lu Zhe heard the voice of someone talking below, and hurriedly walked down, it turned out that a woman was talking to the old doctor, only to hear the woman say: I am two maids on this trip, if you have anything, please ask casually.

The doctor nodded and said, "How long does it take to get to the gravel country?"

The woman thought for a moment and said, "It will take about three days."

The doctor nodded and said, "You can go."

The woman bowed slightly, and walked to the front of the house, which seemed to have a place in front of the house, probably a cab or something.

Later, he only heard a flying beast roaring towards the sky, and then Lu Zhe felt that the house was shaking, but after a while, it stopped, Lu Zhe looked outside, and found that this long-distance flying beast had flown into the blue sky and flew quickly towards the south.

The old doctor sat on the chair, waved his hand at Lu Zhe, and motioned for Lu Zhe to come over.

The doctor coughed a few times and said, "Do you know where we are going this time?"

Lu Zhe nodded and said, "I know, the sand and gravel country located on the edge of the "Endless Desert".

"That's right, we're going there," the doctor nodded, then paused, and continued: Do you know what we're going to do this time?

This time, Lu Zhe shook his head, and then seemed to think of something, and whispered uncertainly: I won't go to find the twenty-four miraculous medicines.

"Hmm," the old doctor looked at him with a smile in his eyes.

Lu Zhe sighed softly, obviously knowing that there would be such a thing.

The doctor looked at him, groaned slightly, and said, "Do you remember those medicinal materials I asked you to find in the Alchemist Guild a few days ago?"

Hearing this, Lu Zhe looked up at the old doctor, thought for a while, and said: "I remember, but I haven't found it for a long time, and besides, those two herbs are ranked among the top five medicinal herbs, how can they be found so easily." After a pause, Lu Zhe's eyebrows furrowed slightly, and he asked puzzledly: What are you asking me to do with those two herbs?

The old doctor clasped his hands together to support his chin, making a thinking motion, and after a while, he only listened to him: These two things are the medicinal materials that you must need to get the twenty-four strange medicines, and you also know that the twenty-four strange medicines have always been known for their domineering and domineering medicinal power. So, I thought about it and decided to help you neutralize it with some herbs, which would reduce your chances of dying, understand?

Lu Zhe thought for a moment and asked: How much can it be reduced?

The old doctor looked at him, stretched out three fingers, and said, "Sancheng."

"It's only three percent," Lu Zhe looked at the old doctor's finger and said with a dissatisfied expression.

"It's not that it's a three-percent reduction, but a success rate of only three-percent," the doctor said calmly.

"What!!" Lu Zhe exclaimed when he heard this.

"Did you make the boiling water scald?" said the old doctor with a helpless look on his face.

"No" Lu Zhe immediately lowered his voice, sat down and leaned close to the doctor, stretched out three fingers and gestured: Sancheng, are you asking me to find death?

"It's not certain death, what are you afraid of?" said the old doctor lightly.

"Why don't you go and eat?" Lu Zhe asked rhetorically.

"I've eaten it," said the old doctor with a nonchalant expression.

"Eat, have you eaten?" As soon as these words came out, Lu Zhe was directly suffocated, and Lu Zhe asked puzzled.

"Do you remember what I told you, I once ate a herb called "Sanmiao Green Spirit Flower", and this herb is the twelfth miracle medicine on the list of miracle medicines," the doctor said lightly.

As soon as these words came out, Lu Zhe was stunned, Lu Zhe looked at the old doctor with strange eyes, and then hurriedly lay on the table, and couldn't wait to ask: How did you get it? How did you feel after eating?......

The doctor looked at him, smiled, and said: This miraculous medicine was accidentally obtained by me in the "vast forest" in the east of the continent when I traveled the world, and I didn't know it at the time, so I swallowed it directly, and as a result, I almost didn't die, if it weren't for some hard skills, I would have died a long time ago, but after I refined it, the increase in my body was unprecedentedly huge, which is probably a great calamity and a blessing after not dying.

Lu Zhe gasped after hearing this, stabilized his mind, and then asked: What is the miracle medicine that appeared in the "Endless Desert" this time?

The old doctor thought for a while, shook his head, and said, "Old man Ye didn't tell me, but he said that this is a fire-attribute miraculous medicine, and let me refine a neutralization pill for you to help you refine the miraculous medicine."

"Master, how did he get this information? It stands to reason that these natural treasures should be very sought-after, how did he get them?" Lu Zhe tilted his head and muttered to himself in confusion.

The doctor poured a glass of water, looked at him, and said: Your master has traveled all over the continent and met many people, although this thing is extremely rare, it is not nothing. Suddenly, the old doctor suddenly lowered his voice, and whispered into Lu Zhe's ear and said: If it was just what your master said, I wouldn't have gone in person, but there is an inexplicable inductive connection between the miraculous medicines, and the miraculous medicines in my body also vaguely sensed that there were traces of miraculous medicines in the south.

Lu Zhe's pupils gradually dilated with the old doctor's words, and when the old doctor finished speaking, he looked at the old doctor in disbelief, the old doctor nodded, winked at him, and then picked up the teacup and drank the tea.

Lu Zhe sat on the chair and was silent.

The flying beast was still flying at high speed in the air, and in the room behind the flying beast, there were two silent people

The flying beast's flying speed was indeed not low, three days after flying away from the Oga Empire, Lu Zhe vaguely saw the shadow of a city in front of him, and then, the temperature in the air rose sharply, and a wave of dry heat came to his face, making people feel dry mouth.

The old doctor slowly came down from the second floor, looked forward from the window, and said lightly: It's almost there, Sand and Gravel Country.

Hearing this, Lu Zhe looked at the gravel country that was about to arrive with solemn eyes, and his hands clenched unconsciously, making a "boom" sound.

Lu Zhe took a deep breath of hot air, and said to himself heavily: Miracle medicine, I'm here.
