After March, Xu Xian left the customs.

In addition to paying enough Qi Gathering Pills and Heqi Pills normally, Xu Xian has also gained a lot in the past three months of seclusion.

His cultivation has improved a lot due to the Sun and Moon Transformation Pill. In the past three months, he has refined three furnaces of Sun and Moon Transformation Pills, including the first one, and has produced a total of four pills.

Three inferior products, one inferior product.

Xu Xian took three of four pills, which was equivalent to three months of seclusion, which was equivalent to having achieved hard practice for half a year. However, even so, it was still much worse than reaching the peak of the third level of Qi refining and revealing the fourth level of advanced level.

As for the Spirit-Slaying Pill, Xu Xian also used it, which has much more effect than the Spirit-Gathering Pill, but it is still much worse than the Sun and Moon Transforming Pill.

Now that Xu Xian is far from the peak of the third level of Qi Refining, he is conservatively still missing to have more than one year of cultivation.

But you should know that Xu Xian has only entered the Five Elements Sect for only a year and has actually reached the third level of Qi Refining. This speed is no different from the elites of the five sects.

Now it is no longer possible to continue to refine the Sun and Moon Transformation Pill at the Small Realm Pill level. The main reason is that there is no material. Xu Xian is embarrassed to find Ye Feigong again.

Compared with the Sun and Moon Transformation Pill at the Small Realm Pill level, Xu Xian is more curious about the magical effect of the Great Realm Pill, that is, the upgraded version of Sun and Moon Transformation Pill.

So he paid an extra share of elixir for one month and planned to go to the secret realm of the back mountain to see if he could pick some rare spiritual herbs for alchemy.

After changing into a clean disciple's uniform, Xu Xian hid the treasure bag in the lining of his clothes, then carried a medicine basket, and walked out with the long sword of the average disciple.

The entrance to the secret realm of the back mountain is not in the outer courtyard, but in the back mountain.

There is a mountain called the Back Mountain at the Five Elements Gate, which is the name of the mountain. Xu Xian has a waist card of the Grand Master of Medicine, so he went out of the outer courtyard and arrived at the entrance of the back mountain.

Here is a cliff, as if the sky sword was left behind by the mountain, and it was not far behind. The cliff was covered with clouds and mist, and I saw an iron cable bridge hanging on it, and I could only see half of it, and half of the opposite part was hidden in the clouds and mist, which felt mysterious.

At this end of the iron chain bridge, there was a pavilion standing, an old man sitting cross-legged, wearing dark brown monk uniforms in five sects. He was probably at least an elder-level master in the five sects.

Xu Xian naturally did not dare to be rude, so he saluted respectfully, and then took out his waist card with both hands.

"Xu Xian, a disciple from the outer courtyard, requested to enter the secret realm of the back mountain."

The old man raised his eyelids slightly and reached out to grab them. The waist card in Xu Xian's hand reached the other party's hand.

After the test, the old man raised his hand and swung his waist card back to Xu Xian's hand.

"Go, remember that disciples from the outer courtyard should not step into the Fourth Realm Monument." The old man reminded him and stopped paying attention to Xu Xian.

On weekdays, there are disciples from the outer courtyard who are ordered to enter the secret realm of the back mountain, and most of them collect medicine and do things.

Xu Xian bowed again, then walked up to the iron chain bridge, then stepped forward, and after a moment, his figure disappeared into the clouds and mist.

Since he was coming to the secret realm of the back mountain, Xu Xian naturally did his homework in advance.

It is said that the secret realm of the back mountain is very large, separated by the five boundary markers as a circular shape. The area in the center is the first boundary marker area and the most dangerous place. Generally, only core disciples of the five sects dare to step in.

Outside, the Second Realm Monument was also divided into the Fifth Realm Monument area. Generally, disciples from the outer courtyard can only move in the outermost area, the Fifth Realm Monument area.

Here, there are some beasts appearing and spiritual herbs, which are relatively not dangerous. If you go deeper, starting from the Fourth Realm Monument, there will be ferocious beasts or even monsters appearing, and the danger level will rise sharply.

Xu Xian knew very well what he was going to come this time, so he had no intention of crossing the line.

Following the iron chain bridge, I could only see a few meters away from my feet, and I couldn't see it any further. Xu Xian was careful and walked for a while before he saw the opposite side.

After walking a few steps, Xu Xian passed through the fog, and his eyes suddenly became clear.

"What a rich spiritual energy!" Xu Xian took a deep breath, feeling his heart and lungs refreshed, like Mu Chunde, and it seemed like he had a sip of iced soda, and there was a sense of comfort all over his body.

The plants here are obviously different from the outside world, with colorful colors, and the trees in the distance are of varying heights. The tallest trees are more than 30 feet tall. You can listen with your ears and birds playing.

In front is a forest, an open space, and a boundary monument stands with the word "five" written on it.

This is the fifth world monument.

In other words, if you cross the boundary marker, you will truly enter the secret realm of the back mountain.

Xu Xian was very excited and lifted the medicine basket behind him and walked in.

To refine the Sun and Moon Transformation Pill at the Great Realm Pill level, in addition to the basic spiritual herb materials, Xu Xian also lacks three rare spiritual herbs, namely Yanyang Grass, Night Fluorescent Flowers and Blood Jade Flowers.

These three things are not planted in the medicinal fields of the outer courtyard. If you want to obtain them, you can only enter the secret realm of the back mountain.

Xu Xian was lucky. After wandering around the mountains and forests around the surrounding area, he found Yanyang grass.

The habit of this kind of spiritual herb is to like Yin and dislike Yang, and it will only be found in cold, humid and sunless places. Xu Xian has memorized the Chinese herbs in his heart and is extremely familiar with the habits and appearances of various spiritual herbs.

A few yang-sweet grasses grow on a shady rock in the forest, and depending on the shape, they are at least five years or more.

Xu Xian was naturally happy, but he did not pick it immediately, but took out a thick black cloth.

The thing of Yang Yancao is magical. If it is shined by the sun, it will wither and die immediately. Therefore, it must be wrapped with something that blocks the sun, otherwise it will lose all the medicinal properties.

Spread the black cloth on the ground, pick it off, and wrap it directly.

However, these few Yang Yan grasses are only enough to refine one furnace, and Xu Xian needs more. Xu Xian, who has tasted the sweetness of the Sun and Moon Turning Spirit Pill, is no longer a bit disliked the ordinary Spirit Gathering Pill.

It’s like eating delicacies from mountains and seas, where can I swallow simple rice?

In half a day, Xu Xian had found more than a dozen Yang Yan grasses and had good harvests, but he had not found the other two medicinal herbs.

But Xu Xian is not in a hurry.

The night fluorescent flowers cannot be seen during the day, or they cannot be recognized even when they see them. Only after night can this magical spiritual flower reveal its true appearance and emit a faint fluorescence.

So if you want to find this medicinal material, you have to do it at night.

When it was night, Xu Xian re-entered the forest and found it.

Under a huge rock, there are several small flowers mixed among the many flowers and plants that are extremely conspicuous, and the fluorescent emitted on the petals are very dazzling under the night.

Found it!

Xu Xian hurried forward, but at this moment, something suddenly jumped out of the flowers and opened his bloody mouth and bit Xu Xian.

Thanks to Xu Xian's quick reaction, he hurriedly retreated and avoided this sneak attack.

It turned out to be a black snake again.

The black snake was curled up among the plants and hiding its body through the night. Xu Xian really didn't notice it, and he was careless. He saw that the black snake was as thick as an arm, about a stubborn length, with a thick head, sharp teeth, and when it opened its mouth, it had a fishy smell. It was obviously a poisonous snake.

Xu Xian was scared for a while.

The black snake failed to attack and rushed forward again. This time, Xu Xian reacted very quickly. He pulled out the disciple's sword at his waist and swung it gently. A sword light flashed by, and the black snake's head was chopped to the ground.

Xu Xian had experienced fighting with evil cultivators before, so he naturally had experience. Besides, a mere poisonous snake was the opponent of Xu Xian, a cultivator of the third level of Qi Refining.

He raised his hand and flew out of his hand, and nailed the snake head that fell to the ground to death.

This is also because Xu Xian is afraid that the snake will not be stiff. If he gets closer and suddenly bites the snake's head, it will capsize in the gutter.

Xu Xian, who has always been seeking stability in his work, naturally would not make such low-level mistakes.

He took away the night fluorescent flowers first, and then Xu Xian looked at the snake corpse on the ground.

"It is said that snake gall is a great nourishing object, so I want to see what is special." Xu Xian walked over and burned the snake's head with the fire-induced technique, then digged the snake's corpse and took out the snake gall.

The snake gallbladder is not small in size, the size of a goose egg. It tear the mucous membrane outside, and there is no smell of fishy smell. On the contrary, it has a strange fragrance.

Xu Xian analyzed that this black snake lives in the mountains and forests of the secret realm all year round, feeding on small animals and various spiritual herbs. Over time, it will have its own spiritual charm.

And the place where it condenses is on this snake gallbladder.

"If it were decades later, this black snake might be able to cultivate to level one monster." Xu Xian murmured to himself. Thinking of this, he opened his mouth and swallowed the snake gall directly.

The texture is smooth and flows directly into the stomach.

Most people dare not eat snake galls, and even ordinary monks may not do this. But Xu Xian is different, his practice is special.

Internal alchemy qi refining method.

The emphasis is on obtaining spiritual energy from all things, and even spiritual herbs can be eaten raw, so eating a snake gall is no problem.

Moreover, the practice emphasizes the use of heart fire to refine the food, so even if there are parasites, they cannot survive the refinement of heart fire.

Xu Xian sat cross-legged and pinched a sword trick first. The disciple's long sword hung on the air, circling around Xu Xian.

This is to prevent external objects from being interfered with during practice, such as other mountain beasts. Although Xu Xian’s sword is not a spiritual sword, it can be compared with a lower-level spiritual sword with the blessing of his sword intent.

If an external object approaches, this long sword will kill itself and protect the master loyally.

One hour later.

Xu Xian opened his eyes.

I only felt that my eyes were clearer. This black snake gall can improve my eyes and increase my resistance to poisons. The improvement of my cultivation is not as powerful as Xu Xian thought.

If you have to die, it means that it is similar to a spirit-snatching pill, which can directly improve your cultivation for ten days.

This is already good.

"No wonder the ancestors before the Five Sects wanted to create this secret realm of the back mountain to train the disciples of the Five Sects. Practicing here is much better than staying in a house."

Xu Xian got up and put away his sword, but saw several corpses of hares and poisonous insects around him. He knew that he was approaching him accidentally while practicing and was killed by his long sword.

In other words, in such places, unexpected dangers may be at all times.
