As the sun rose and set, the day passed.

It was already dusk, and the afterglow of the setting sun lit up the sunset on the horizon, and the brilliant sunset dyed the whole sky red and the earth a beautiful red. The birds returned to their nests, the squirrels returned to their holes, and the fish were still swimming in the river.

The doctor was still sitting by the river fishing, the clear water reflecting the red of the sky. He looked up at the beautiful sunset and the orange-red sunset, and the afterglow hit his face, red like a shy girl. A smile appeared at the corner of his mouth: "It looks like tomorrow is going to be a good day." He looked back at the cave where Lu Zhe was alchemizing, his eyes flickered a few times, and then he turned back and continued fishing.

The sunset gradually sinks, the bright red sky is gradually replaced by the night, the sunlight is lost, the white clouds also turn black, this night, the bright moon hangs high, the night is cold and the stars are sparse.

The wind is up, the breeze.

The old doctor put away the fishing rod in his hand, he caught a day's fish, although he didn't catch a single one, but he didn't feel bored at all, he thought that fishing and chess can best hone people's patience and willpower, he also likes to play chess, but playing chess alone inevitably seems too lonely, and the person who used to play chess with him is now no longer by his side.

There was a hint of sadness and longing in his expression.

The old doctor lowered his head and looked at the fishing rod in his hand, in order to make it easier for him to carry the fishing rod, so he spliced it with green bamboo of equal length, he ripped off the fishing line, and then unloaded the fishing rod back into the ring. Suddenly, he remembered that Lu Zhe had said that he had underestimated the IQ of the fish, and that he had never put bait in fishing, and that Lu Zhe had said that there was a problem with his fishing method. That person was his good friend Ye Lao.

He suddenly smiled, and people always laugh when they are immersed in good memories. He is no exception.

He stood up and moved his muscles for a moment, and then walked towards the cave where Lu Zhe was. Six hours have passed since Lu Zhe started alchemy, and he is now very worried about Lu Zhe.

"Am I being too strict with him, although he is a genius, the difficulty and risk of leapfrogging alchemy are not low" He walked faster and faster, and soon came to the entrance of the cave.

Just as he was about to enter the cave to take a look at Lu Zhe's situation, a terrifying high temperature of gravel and gold suddenly rushed towards him! He frowned, his right hand clenched into a fist, and the terrifying high temperature suddenly stopped three feet in front of him, as if he had hit an invisible wall.

"Not good. It's blown up!" Feeling the terrifying heat, this thought flashed to the doctor's heart.

He hurriedly walked into the cave, and as soon as he entered the hole, he bumped into a black object head-on, and the old doctor's body subconsciously slapped it and slapped the black object on the cave wall.

"Oh, who hit me?" Lu Zhe's voice came into the ears of the old doctor.

The old doctor was stunned for a moment, and then fixed his eyes to see that the black object he had just hit was Lu Zhe. He hurriedly walked over, and Lu Zhe was lying on the cave wall moaning. Helped up by the old doctor, he touched the left side of his face, and said angrily: Why did you sneak attack me, Master.

The doctor hurriedly apologized: I'm sorry, I didn't see it clearly. Then he helped Lu Zhe out of the cave.

As soon as I came to the outside of the cave. The terrifying high temperature immediately dropped a lot, and the cool breeze blowing in his face made Lu Zhe breathe a long sigh of relief, and he wiped the sweat on his head. A little weakly said, "I succeeded Master." He opened his right hand, and a pill the size of a dragon's eye lay in the palm of his hand.

"Well done. I knew you could," said the doctor, delighted.

Lu Zhe smiled faintly, and then put the little spirit pattern pill in front of the old doctor. Said tiredly: Master, look at it, I have no problem refining.

The old doctor took the little spirit pattern pill, then took out a box from his arms, and after putting the little spirit pattern pill in the box, he helped Lu Zhe to lie down, and said: You are very tired now, don't talk, hurry up and rest.

Lu Zhe nodded, then closed his eyes, and after a while, the snoring came up.

After placing Lu Zhe properly, the doctor came to a bright place, took out the box containing the little spirit pattern pill from his arms, opened the lid, and the little spirit pattern pill was a little shiny under the moonlight. He took out the Little Spirit Pattern Pill, took a closer look at it through the moonlight, and found that the gloss and lubrication of the pill were perfect, and the fragrance of the medicine was also refreshing.

"Yes, it's the real 'Little Spirit Pattern Pill', the most rare thing is that there are very few impurities" The doctor carefully put the Little Spirit Pattern Pill back into the box, and then closed the lid and retracted it into his arms.

He looked at the bright moon, and under the moonlight, the old doctor's white clothes were even whiter, and he took out a horizontal flute from his sleeve, sat cross-legged on the stone, and began to play.

The melodious sound of the flute spreads, intertwined with the sound of the water and the wind blowing in the small river to form a natural tune.

The sound of the flute gradually changed from high-pitched to low-pitched, twists and turns, and it was contemplative.

"It's so rare that you can play the flute here, I haven't heard your flute for thirty years," suddenly a voice interrupted the doctor's playing.

The old doctor stopped playing, and a smile appeared on his face, but he did not turn around, but turned his back to the person behind him and said, "I have something on my mind, can't I solve it by playing the flute?" He turned around, the smile on his face was gone, his eyes were like sharp knives, and he said word by word: Dugu old ghost!

A man in a black robe stood in the shadows of the woods, and after hearing the words of the old doctor, the man laughed as he stepped out of the shadows under the trees, the moonlight shining on his body, and his long purple hair was very beautiful. He smiled and said, "Can't I come to meet my old friend?"

The old doctor suddenly laughed and said, "Old friend, hahaha, you and I have been fighting for hundreds of years, and if you think about it, it can indeed be regarded as a deep friendship." What are you doing here?

"Don't be so nervous, relax and relax" The man in black sat on a stone with a smile, opened the paper fan in his hand, and said: Sit, don't worry, I won't do anything. Besides, even if I do something, you will easily find out and solve it with your ability.

The old doctor smiled, sat down on the stone, and said, "Old ghost Dugu, how did you find here?" Based on what I know about you, you will never come to such a remote place, is there something wrong?

"Hahaha" The man in black looked up to the sky and smiled, and then said in an admiring tone: It's worthy of you, and your observation has not decreased at all.

The doctor also smiled, and said in a strange tone: For people of our level, eyesight can't decline at all.

The man in black closed the paper fan in his hand, and then said while playing: I just happened to pass by here, and I heard the familiar sound of the flute, so I came over to take a look, and it was really you.

"You're looking for me this time to catch up with me?" asked the doctor.

"Not really," the man in black said with a smile.

The two looked at each other, and the dark clouds slowly covered the moon under the blowing of the west wind, and the night quietly fell like a large net, covering the whole land.

The dark and dreary night seems to be smeared heavily on the sky. In the night sky, the stars were sparse, and the whole earth seemed to fall asleep, and the occasional leap broke through the silence, and then fell into infinite silence.

"Whoa".

The west wind blew and removed the dark clouds that had obscured the moon, and the earth was lit up again.

The old doctor and the man in black were still sitting motionless, the two of them had not changed much from just now, but there was still a slight change.

The man in black inserted a silver needle in his left arm, and the silver needle reflected the light of the moon and shone brightly. The old doctor sat there in perfect condition, looking the same as before.

The man in black looked at the silver needle on his left arm, stretched out his hand and pulled out the silver needle, and said with a smile: I haven't seen you for many years, but you still wear Yang in a hundred steps.

The old doctor smiled and said, "Pass the award."

The man in black threw the silver needle in his hand, then stood up and opened the paper fan, fanned it a few times, and said, "Don't you ask me where I got Old Man Yan?"

The doctor shook his head and said, "I know you won't say it, so I'm too lazy to ask."

The man in black laughed and said, "Yi Si Miao, we will have a meeting later." With that, he vanished.

After the man in black disappeared, the old doctor blinked, and then spat out a mouthful of blood with a 'flutter', he pulled the clothes on his chest, and a clear black palm print appeared on his chest.

The old doctor looked at the black palm print on his chest, and around the black palm print, there were many black lines as thin as hair like spider webs that were spreading at a very slow speed.

"I didn't expect his eagle venom claws to reach such a realm" The old doctor stretched out his right hand, and a green flame rose in the palm of his hand, he pressed his right palm to his chest, and after a while, he took away his right hand, and the black palm prints and fine lines were no longer there.

The old doctor wiped the blood from the corner of his mouth, then tidied up his clothes, looked at the cave where Lu Zhe was resting, and said to himself: Boy, your future enemies are very terrifying. (To be continued......)
