Sunset Forest.

Cries of pain were heard at the foot of a mountain.

"Bang Bang!"

"Hiss~ It hurts. ”

"Stop, Master, stop fighting, I'm hungry, I really can't run. Lin An desperately dodged while begging loudly for mercy.

The old man didn't know if he had taken the wrong medicine today, so he took him to the forest early in the morning, and casually threw away a set of fifty pounds of iron armor for him to put on, and then took out the familiar whip from the storage ring without hesitation......

"Hmph, if you can still open your mouth to beg for mercy, it means that you still have the strength to spare. The silver-haired old man waved his pink whip and said disdainfully, "Keep running, don't stop!"

"Goo~"

Lin An had no choice but to continue running, and his stomach kept ringing since just now.

"Smack!"

"Hiss~"

It didn't take long for another whip to hit his body, and Lin An, who was in pain, gasped. This ghost whip doesn't know what attributes, not only is it pink, but the pain will accumulate every time it is hit, making it even more painful next time.

The point is that despite the abnormal pain, there is only a cutaneous trauma.

"Puff~"

Lin An flashed a spur from the silver-haired old man, but his left foot accidentally stepped on the air and fell.

"Boy, are you alright?" the silver-haired old man put away his long pink whip and floated down worriedly.

"Master, I'm fine. ”

Lin An pushed away the fallen leaves on his body, stood up and patted the dust, and looked up.

This hole is so deep, roughly estimated that it is more than ten zhang deep.

Seeing that Lin An was fine, the silver-haired old man took out a huge night pearl from the storage ring and floated forward with his aura.

As the light of the Night Pearl illuminates, the depths of the gloomy cavern reveal its true side.

In front of one person and one soul is a passage made of spirit wood boards, and there seems to be some words written on the walls on both sides of the passage, but Lin An can't understand it, this text is a bit like the oracle bone inscription of the Azure Star in the previous life.

However, it is clear that this is not a natural cave, but rather an ancient relic from a certain era.

"Tut-tut, boy, you're in luck. The silver-haired old man looked at the words on the cave and said to Lin An with a smile, "This is a retreat place for ancient miscellaneous cultivators. ”

"Miscellaneous cultivators, what is that?" Lin An muttered in confusion.

"The so-called miscellaneous cultivation refers to those monks who know everything in all aspects of their cultivation, but are proficient in none of them, and who pursue and aspire to an all-round profession. The silver-haired old man spoke.

Lin Anxin said, isn't this how he was in his previous life, he could order everything but was not proficient in anything.

Pierced in the heart, old iron.

Walking down the passage to the end, you will be greeted by a dilapidated wooden door.

Lin An carefully pushed open the wooden door and quietly walked inside, and found that it was a room six zhang long and two zhang wide, with several rows of wooden bookshelves on the left and right, and books of different thicknesses on them.

It is strange that such a damp and dark underground space does not have the slightest smell of decay.

Behind the desk in the center of the room, a white skeleton sat on a chair with its hands folded. The desk and the surrounding floor were cluttered with books, some of which were mixed with handwritten materials.

Lin An casually picked up dozens of pieces of paper on the ground and found that it was an unsent letter written in modern common language.

Qing'er girl, it has been decades since the last time the imperial city was parted, and I miss Qing'er girl very much, I don't know if Qing'er girl misses it, and I still remember the first encounter in Qinglou in Cangzhou City......

There are a lot of memories in the back, Lin An skipped and looked directly at the last paragraph.

In the past ten years, I have been painstakingly studying the convenient way of alchemy and refining, and recently I finally have some results, and I specially sent a letter to share it with the Qing'er girl.

Turning over this page, the next dozens of pages are relatively complex graphic introductions, and Lin An was directly confused.

What is this all about?

Seeing the end, Lin An found that he only understood part of the text introduction.

To put it simply, it is to learn the formation, arrange the formation to assist the refining tool to engrave the inscription, and then use the refined special Dan furnace utensils, plus the special auxiliary formation to achieve continuous and uninterrupted batch refining of the perfect pill.

"Yes, I like the idea. The silver-haired old man didn't know when, and floated behind Lin An.

Lin An put all kinds of materials and books into the storage ring, bowed in the direction of the skeleton to show respect, and was about to dig a pit to bury him, when a middle-aged phantom suddenly appeared directly above the skeleton.

"Later people, I, Zhang Nuo, thank you for your respect, please accept the treasure I left behind. ”

With that, as the middle-aged man's phantom waved his hand, the skeleton and chair fell backwards along with the floor, revealing the staircase passage directly below.

Treat people with courtesy, there will be a good reward, and the ancients did not deceive me.

After Lin An stepped into the passage, the two rows of oil lamps on the wall not far away did not know what structure was used, and they were lit one after another, illuminating the originally gloomy passage.

By the light, you can see that there is a stone door at the end of the passage about ten feet away.

Lin An walked to the stone gate and tried to push it with his hand, but he didn't move, it seemed that he couldn't open it with brute force alone, so he could only look for the mechanism.

I searched the stone door, but I didn't find any mechanism that could be turned or pressed.

"Boom!"

"Stupid apprentice, look at the square hole in the middle of the door, isn't there a text introduction on it? The silver-haired old man was a little impatient on the side, and stepped forward and struck a violent shudder.

Lin An touched his head and looked at the words, but he couldn't understand the ancient characters similar to oracle bone inscriptions, so he had no choice but to look back at the old man embarrassedly for help.

"Alas, the world says that it's terrible to be uneducated, but the old man has seen it. The silver-haired old man shook his head with a smile, glanced at Lin An with the rest of his eyes, and said, "What is written on it is that the square key inserted on the table can be opened by turning it three times to the right." ”

Square keys?

Lin An remembered that there was indeed a long strip of metal in the shape of a square on the desk before, but because the appearance was very old, he didn't care too much about it at the time, but he didn't expect it to be the key.

Took out the square key from the storage ring, inserted it and turned it three times to the right, the stone door shook slightly, the internal mechanism operated, and the entire stone door slowly rose upward.

A moment later.

The stone door rose to the top, and with a thud it froze.

Lin An held the old man's night pearl, stepped into it carefully, looked around, when he looked in the direction of his left hand, his eyes suddenly lit up, his little heart beat violently, and his handsome little face was even more rosy with excitement.

In front of me was a much smaller darkroom, two feet long and six feet wide, and the left side of the darkroom was full of gold, silver and jewels, shining in the light of the night pearl.

Getting rich overnight is beautiful.

"It's really useless, just these mundane garbage, and it deserves such joy?" the silver-haired old man shook his head, turned to look at some strange utensils on the right side of the dark room, and muttered to himself from time to time, "Oh, it can be combined like this, it's really strange." ”
