When An Xiaoyu heard this, he ran over and hurriedly asked, "What's the situation?"

Mi'er pulled An Xiaoyu's hand and didn't explain much: "Come with me!"

didn't ask much, and walked side by side with Mi'er. Along the way, I found that there were many traces of being trampled on the grass, and I didn't have to guess to think that it was caused by Mi'er collecting the spirit grass just now.

"Is the spirit grass harvested big?" An Xiaoyu couldn't help but ask.

"Hehe, this time, most of the spirit grasses are mortal-level low-grade, but there are three mortal-level medium-grade ones, and there is one mortal-level high-grade spirit grass. I originally planned to be able to get some mortal-grade spirit grass, but I didn't expect there to be unexpected surprises. Mi'er said happily.

"Isn't the grass generally green, how can you tell the grade of the fairy grass?" An Xiaoyu asked.

Seeing An Xiaoyu's confused look, Mi'er took out a few spirit grasses, and explained with a smile while pointing: "Spirit grasses, spirit pills, and spirit pills are divided into mortal level, earth level, heavenly pole, god level, immortal level, and chaos level according to the heaven and earth energy and medicinal power they contain. Each level is divided into lower, medium, and upper grades. Of course, mortal-grade spiritual grass grows in the mortal realm, and generally low-grade spiritual grass is more common, and mortal-grade medium-grade elixirs are rare, and mortal-level high-grade elixirs are even more difficult to find. I didn't expect to be so lucky this time, I was able to collect a mortal-grade immortal grass, or a soul-nourishing soul grass, which would help me a lot. ”

Seeing An Xiaoyu's envious gaze, Mi'er comforted: "Don't be disappointed, there is a low-grade forging grass in it, which can temper your muscles and bones, which is very good for you to enhance your physique, and there is also a medium-grade refining grass in the mortal rank, which can temper your divine sense, and it will also be of great benefit to the growth of your divine consciousness." Your physique and soul are too weak now, first take the lower-grade spirit grass to improve your physique, and then slowly take the medium-grade spirit grass, the energy of the high-grade spirit grass is too great, you still have to improve your cultivation and then take it. I'll refine the Forging Grass and Refining Grass into elixir in a while, and if you take it again, the effect will multiply several times. ”

"That's great. An Xiaoyu said excitedly, and then asked, "Mi'er, what is the elixir?"

"The elixir is a medicine synthesized by the alchemist using the prescription to select the appropriate elixir and refine it together, and the effect is often several times that of a single elixir, for example, several spiritual herbs worth a hundred yuan stones, if they are refined into an elixir, they may be worth five hundred or higher, and the value often depends on the ability of the alchemist. For the same spirit grass, the more advanced the alchemist, the more he can refine the medicinal liquid ingredients in the spirit grass, the stronger the proportion and heat of the synthetic elixir, and the greater the effect of the refined elixir, so many high-level alchemists are more popular and have more status than cultivators of the same level. Mi'er spoke eloquently.

"Is there a spirit pill in the mortal realm?" An Xiaoyu asked again.

"Spirit grass and elixir are available in the mortal world and other cultivation worlds, what is in the mortal world is the mortal grass and ordinary medicine, and the immortal world is the real immortal grass and immortal medicine, there is no elixir in the mortal world, and the elixir can only be refined by the alchemists of the immortal world. Not everyone can take the elixir, taking the elixir must have a strong physique, how can the flesh and blood of a mere mortal withstand the huge energy of the elixir? Mi'er took the trouble to explain.

"Then we can collect a large number of spiritual herbs and elixirs in the future, so that eating grass and taking medicinal herbs will improve our cultivation. An Xiaoyu said longingly.

"It is a three-part poison, and the spirit grass and the elixir are only auxiliary means of cultivation, and no matter how good the spirit grass and elixir are, they will leave more or less dregs after being absorbed by the body, which will have an impact on the purity of the essence and blood veins. No creature can be healthy and live a long life by taking medicine, and cultivators, in the final analysis, still have to rely on their own cultivation to go further. Mi'er said.

"That's right. I will rely on my own ability to cultivate. An Xiaoyu secretly made up her mind.

As they spoke, the two came to a mountain wall.

"There's nothing bare here?" An Xiaoyu asked curiously, looking at the stone wall.

"Hehe, this is a hidden formation, there must be a treasure in it. Mi'er said proudly.

"How do you get in?, will you crack the formation?" An Xiaoyu asked.

"How can a mere yellow-rank formation stump me? Who am I? Ancient power! I can break a formation more advanced than this. Today I will teach you the formation, and you will break it. Mill said lightly.

"Can I also learn?" An Xiaoyu said excitedly.

"I can teach you, and whether you can learn it depends on your understanding. Mi'er stretched out her little hand and stroked it somewhere on the mountain wall, and a huge square grid of golden streamers appeared on the smooth mountain wall, and there were nine hundred and eighty small squares in the grid.

"I want to learn, I want to learn, I can learn. An Xiaoyu said.

"Don't brag just yet. "Mi'er looks dignified" This formation is also a high-level formation in the mortal realm, and it has a famous hall, called the 'Eighteen Netherworld Great Array', which was set up by the peerless power to protect his tomb during his lifetime. The entire large array is filled with countless resentful ghosts and netherworld qi, ninety-nine eighty-one small square is void and real, among which there are eighteen organs, and the others are array eyes, the cracker must inject vitality into the square of the array eye, if there is a formation eye selection error, the mechanism will be activated immediately, and the netherworld qi will erupt out, the light one will be trapped in the array, and the heavy one will be killed immediately. ”

"Is this big array so powerful?" An Xiaoyu scratched his ears and cheeks anxiously.

"The master here is guarding this place with such a dangerous array, which means that there must be treasures here, do you dare to try it?" Mi'er analyzed.

"Try it, it's a big deal, it's a big deal, wealth and danger are sought, I don't want to live in a nest for the rest of my life. An Xiaoyu said without hesitation.

For example, the number one represents that there is only one mechanism in the nine grids around, and the number two represents two mechanisms in the nine grids around, and so on, and there is a time limit, and this 'Eighteen Netherworld Array' needs to be completed within sixty-three breaths. Mi'er said.

"If we stab the mechanism in the first blow, we will both die. An Xiaoyu said.

"No, the treasure is reserved for those who are destined, if the owner of the tomb does not want to pass on the treasure to future generations, is it good to destroy it before death? Why keep it? It's just that a master like the owner of the tomb doesn't want to leave the treasure to the mediocre. So the first time, no matter which square you input Aura, it won't activate the trap. Every time this formation is activated, the position of the mechanism changes randomly. Otherwise, those tomb robbers can let their subordinates try to find the mechanism one by one, they must have tried, and a few died, and found that the position of the mechanism changed randomly every time they activated it, so they didn't want to crack it. Mi'er was confident.

"It's okay the first time, but will it be lucky in the future?" An Xiaoyu still said uneasily.

"What are you afraid of with my guidance? Not to mention the small eighteen mechanisms, I have cracked all ninety-nine mechanisms. Come here with your ears and I'll tell you the mantra. Mi'er said mysteriously.

"Two numbers are sandwiched between one and one (-1-2-1-), two numbers must have a mechanism in one place, and the number two must have no mechanism;

Two numbers are sandwiched between one (-2-2-1-2-2-2-), the number one in the center must have a mechanism, and the number two must have no mechanism;

Two numbers two sandwich n three (-2-3-3-2-), two and three sides are full of organs;

Two consecutive numbers are on the side (|2-2-), and both sides are traps;

The three numbers in a row are on the side (|1-1-1-), and the one away from the side has no mechanism;

The three numbers in a row are on the side (|1-1-1-), and the one away from the side has no mechanism;

Three numbers in a row are sandwiched in the middle (|1-1-1|), the one in the middle has a mechanism, and the one on both sides has no mechanism;

Four consecutive numbers are sandwiched between (|1-1-1-1|), with one on either side having a mechanism and one in the middle without a mechanism. ”

"Isn't this a minesweeper game guide?" An Xiaoyu said casually.

"What Minesweeper?" Mi'er asked.

"Oh, it's the same game I used to play on computers in my past life. An Xiaoyu said.

"That's great, it's safer if you play. Mi'er said happily.

"Okay, fight. An Xiaoyu silently recited the mantra twice in his heart, and stretched out his hand to the square to pat.

A pure vitality was injected into the square of horizontal and vertical two in the upper left corner, and this square lit up silently with a number "two", An Xiaoyu did not hesitate to slap his palm towards the other selected squares, and the numbers continued to light up.

Seeing Mi'er's heart trembling, she said secretly: "This little madman, don't think about it, but don't shoot it on the machine! Otherwise, we both have to finish playing." ”

In less than thirty breaths, sixty-three small squares lit up with numbers, and the smooth stone wall creaked open, revealing a deep hole the size of two zhang.

Mi'er patted An Xiaoyu's shoulder excitedly, "Little stone, you are awesome, I used more than forty breaths when I first cracked this formation, you are faster than me, it seems that your little head is smarter than me." ”

An Xiaoyu said proudly: "It's average, my heart is also scared, and I fought hard." Let's go in and see. ”

"Okay, let's go in. Mi'er entered the cave and said, "Follow me carefully, I'll see if there are any mechanisms in front." ”

The two of them moved forward cautiously, the cave was tortuous, the ground was uneven, but it was quite safe, and after entering more than ten zhang away, the eyes suddenly opened up.

There was a scene in front of them that made the two of them stunned, this is in the tomb, it is clearly a fairyland. In the pale red mist, flowers are in full bloom, green trees are in full bloom, streams are babbling, and colorful butterflies are flying.

Seeing the beautiful scenery, Mi'er and An Xiaoyu suddenly felt relaxed and happy, jumping to pick fresh fruits and chase bees and butterflies.

Frolicking, came to the middle ground. A huge pond appeared in front of the two of them, the water was distinctive, bright red as blood, bubbling and bubbling, and the thick mist evaporated from the surface of the pool water and drifted around.
