The flames swirled in a circle in the stone hall and stopped above the two of them. Shen Cheng glanced at the firelight curiously, but he didn't panic and asked anything.

The little old man gently made a gesture with his hand, and the flame immediately fell into his hand, revealing the prototype, which was actually a talisman.

Tongshi Sanren lowered his eyes slightly for a moment, reopened his eyes and said, "It's just right! Apprentice, you have been cultivating very hard these days, and tomorrow as a teacher, I will take you out to travel and relax." ”

"Really?" Shen Cheng was really a little excited when he heard his master's words, since he went up the mountain for nearly half a year, Shen Cheng only cared about meditating and practicing exercises all day long, and he had never come down the mountain at all!

At this time, he heard that he was going to go out with his master to travel and relax, so naturally he suddenly came to his senses.

Early the next morning, the master and apprentice left the cave one after the other and walked down the mountain.

When I came to the foot of the mountain, I saw a small bag on the waist of the Tongshi Sanren, and a worn-out peachwood long sword appeared out of thin air, floating a few feet above the ground.

"What is this?" Shen Cheng pondered in his heart, "Could it be that this is the master's magic weapon? ”

Sure enough, Tongshi Sanren stepped on it steadily, turned around a little proudly and said to Shen Cheng with a little smirk: "Come up."

"Huh?me?" Shen Cheng looked at the master with a panicked face and said, "Master, I, I'm afraid I can't do it, right?!"

"What's not to do, what are you afraid of as a teacher?" said that the little old man actually put his old face on the board, and changed the appearance of the smiling teacher in the past!

"Oh......" Shen Cheng agreed helplessly, his eyes wide and unblinking, staring at the drifting peachwood sword, but the one under his feet was changed to half a step, slowly rubbing forward.

The little old man reached out and grabbed the back of Shen Cheng's neck, and carried him to the peachwood sword, which suddenly sank down.

Shen Cheng also exclaimed in surprise, and was about to fall off it, and hurriedly raised his two arms to control his balance with a panicked face. The little old man pressed him on the shoulder again, which allowed him to stabilize his figure.

The little old man put one hand on Shen Cheng's shoulder, said "Stand firm", pinched the fly that never left him with the other, and shouted: "Disease".

Shen Cheng felt the peachwood sword under his feet, like an old donkey that could not move heavy objects, trembling and slowly rising upward, he quickly measured his body and put his feet together, and buckled the narrow sword body of the peachwood sword with the soles of his feet, carefully maintaining his balance, but he still couldn't hold back a little.

At this moment, Shen Cheng's heart had already risen to his throat, and his whole body was trembling like chaff! Fortunately, Master's hand never left his shoulder.

Shen Cheng pondered and wanted to grab something, but apart from the master standing next to him, there was nothing to catch! He simply quietly grabbed the corner of the master's robe, and his heart was a little more stable!

At this time, Master's words came into his ears again: "Take a breath of true qi and stay in the divine court, close your eyes to stabilize your mind, take root under your feet and move with the sword, you don't have to stretch your body too tightly!"

Shen Cheng hurriedly closed his eyes and did as the master said, and it really worked! The wooden sword under his feet hummed slightly, the sound of the whistling wind came from time to time in his ears, and there was a damp and slightly cool feeling on his cheeks from time to time.

"It's the first time you've flown it, right? The little old man playfully and with a little smug laughter reached Shen Cheng's ears!

"The first time you fly? Isn't this nonsense? Don't you still play! You must know that when you come out to travel, you will step on this broken thing and fly all over the sky, and the ghosts will come! What is so fun about this, it is better to travel in the mountains and rivers and wander around!" Shen Cheng pursed the corners of his mouth and thought to himself, but he didn't say anything.

After a while, Shen Cheng tried to slowly open his eyes, and exclaimed "Ah", he almost didn't hold the Divine Court and fell from the flying sword, and after a shake, he quickly raised his breath and stood firm again!

At this time, he and his master were already hundreds of feet high in the sky, facing layers of white mist.

"Is it a cloud?" Shen Cheng looked back at the little old man excitedly. Master was looking into the distance, and he didn't know when he took his hand off his shoulder, could it be that he had always been ...... Shen Cheng was a little scared when he thought of this, and reluctantly settled down!

He slowly lowered his head again and glanced in the direction of Jinxia Mountain, which was now like a big green caterpillar lying on the ground, getting farther and farther away from him!

"Master, where are we going?" Shen Cheng couldn't help but ask.

"As a teacher, I want to go to the Fang Market of Nanliang Yunzhu Academy and sell a few spirit grasses for some spirit stones. The little old man glanced at Shen Cheng, and then continued to look ahead and replied casually.

"Spirit Stone, what is a Spirit Stone?" Shen Cheng said curiously.

The little old man raised his hand and twisted his beard for a while and replied, "This spirit stone is an ore that contains the spiritual power of the five elements, and it is absolutely indispensable for us monks. It can not only allow monks to meditate and practice to absorb spiritual power or replenish their missing mana, but also allow monks to use it as a currency for buying and selling, just like money in the world. And some things such as the arrangement of forbidden formations by immortal cultivators also need to consume this spirit stone. ”

Shen Cheng blinked: "Trade and trade with spirit stones, don't you use gold and silver treasures?"

The little old man smiled and said, "Hahaha, gold and silver treasures, those yellow and white things are useless to us monks!"

"This spirit stone is divided into four grades by the monks: lower, middle, upper and best, it can also be said to be low, medium, high and top grade spirit stones, the higher the grade spirit stone, the more pure and full of spiritual power it contains. Every hundred low-grade spirit stones are about the same as the spiritual power and value contained in a medium-grade spirit stone, and so on for each grade. Although this seems to be the case on the surface, in fact, no monk is willing to exchange high-grade spirit stones for an equivalent number of low-grade spirit stones! Because the higher the grade spirit stone vein, the more precious and rare it is. And when the monk is replenishing mana, a medium-grade spirit stone is much faster and more convenient than a hundred low-grade spirit stones. Therefore, when the monk trades, he prefers to accept the equivalent spirit stone of high grade. The little old man explained a few more words.

"Oh, what does that spirit stone look like?" Shen Cheng had heard of the fact that the immortal cultivator only used spirit stones, and this spirit stone was still so useful, he really wanted to see it!

The little old man patted the small cloth bag on his waist, and there was an extra milky white stone the size of a pebble, smooth as jade, and there was a slight halo on the surface, as if he was a little spiritual, and said: "This is a metallic low-grade spirit stone."

Shen Cheng took the stone, felt a cool and slippery feeling, and checked it with his hand, which didn't weigh much, and asked, "Then how do you use it to replenish mana?"

"Your current cultivation is still shallow, and you can't feel the spiritual power on this spirit stone, and you can use it when you refine the exercises for a few more layers!" The little old man took Shen Cheng and handed it back, and as soon as he turned it over, the spirit stone disappeared.

Shen Cheng knew that the master must have put the spirit stone back into the small cyan bag on his waist. He has also been curious about this bag for a long time, but he has never dared to ask Master.
