The thought disappeared, and a dark book appeared in Lu Xuan's hand.

The book is like a flowing water, and there is a strange softness in the hand, which is dark, and when you look at the cover, you have the illusion that the soul is going to be inhaled.

Lu Xuan froze his mind and condensed on the dark book in his hand, and suddenly, detailed information about it appeared in his mind.

["Netherworld True Water Forbidden Law", the six-grade exercise, is the fundamental cultivation method of the Ancient Evil Sect Netherworld Sect, cultivated to the depths of the essence can be used to display the Netherworld True Water, the true water has the effect of melting all things, can dissolve the soul, the body, and even the magic weapon. 】

"The six-grade exercise method is at the same level as "Blood Nerve", but you can try to practice."

Lu Xuan was happy in his heart and thought secretly.

"Blood Nerve" is too domineering and conspicuous, and it is easy to attract people's attention after cultivation, this "Netherworld True Water Forbidden Method" can be known by looking at its efficacy, it is a superior technique for destroying corpses and destroying traces, suitable for assassination, yin tricks and other occasions, just suitable for Lu Xuan of this character.

He opened the page of the book, swept it slightly, and a phantom shadow of a dark river that stretched for thousands of miles appeared in the sea of his knowledge, meandering and changing.

"Fortunately, the effect of the pure glazed tea leaves I took before is still some, otherwise, with my qualifications, looking at these six exercises is like browsing the book of heaven."

Lu Xuan sighed in his heart.

There are still two pieces of pure glazed tea leaves left, for Lu Xuan, who has a low understanding, the effect of these five-grade elixirs is extremely good, and he plans to see if he can find a way to get another spirit seed or spirit plant seedlings.

In addition, the light group reward issued also made him extremely satisfied, the six-grade marrow-clearing jade liquid is the high-grade spiritual object that helps promote the knot, and there is also the six-grade exercise "Xuantian Qing Subtle Method", and the lower part has to be obtained from it!

After harvesting the five-grade Youquan flower, Lu Xuan paid attention to the rest of the evil spirit plants in the underworld area.

Under the nourishment of the evil qi of the bronze halberd that he had exchanged from the hands of the Mu Dao people before, the evil qi had already entered the rapid growth period, and the evil qi around the gray and white plants was permeated, isolating other spiritual plants.

The transparent progress bar under the Yin Crying Wood was about to be full, and since it was not extremely urgent, Lu Xuan also saved some Naling Grass Beads, planning to use them at critical moments in the future.

He took out the Mourning Bell from the storage bag and controlled a large number of pure Yin Spirits to fly out and use it to raise the Yin Wailing Wood.

A little further, a sharp whistling sound came from Lu Xuan's ears.

Following the prestige, I saw that the Evil Tree Demon and the Demon Vine, which had grown to a certain scale, were fighting fiercely.

The face of the old woman on the trunk of the demon tree demon was hideous, and the black trunks were like spears, stabbing at the demon vine in a storm.

The combat power of these five-grade spirit plants is amazing, but the demon vine is also not to be underestimated.

The two are of the same grade, and the demon vine is even more out of the category of spirit plants, with faster action, wider range, stronger ferocity, and far more years of growth than the demon tree demon, so the result is obvious.

The Evil Dryad was tightly entangled by gray and white vines, revealing only the part with vague facial features, and under the background of the tentacle-like vines around it, it looked even more impotent and furious.

The demon vine master vine was held high and shook it from side to side slightly, as if expressing his inner disdain for the demon tree demon.

"You're still a little tender."

"If it weren't for the same cave, I would have eaten it hundreds of times."

After passing such a thought to the Demon Tree Demon, the Demon Vine retracted its tentacle-like vines and crawled directly in the direction of the Misty Immortal Peach like a long snake.

"This demon vine is quite enjoyable, come here to abuse the little brother of Lingzhi, do a warm-up, and go to the fairy peach to enter the world of lust, what kind of fairy life to live."

Lu Xuan shook his head, checked the Evil Tree Demon, and after seeing that there was no abnormality left, he comforted him a few words, and then walked to the rest of the evil spirit plants.

The Holy Child Fruit Mother Plant was extremely dedicated, and under the impetus of Lu Xuan, two more Holy Child Fruit Plants were born.

"You have more children, I have more trees, make a little more contribution to Lingtian, and then meet your requirements."

Lu Xuan drew a big pie for the mother plant, and asked it to willingly give birth to a few more spirit seeds for himself.

Although the number of spirit seeds produced is limited, if the subjective initiative is strong, the yield can still be slightly increased.

"There aren't many fresh monk demon beasts, so I have to find an opportunity to get some."

In front of the Five Organs Treasure Plant, he took out a fresh Five Organs from the gluttonous insect sac, processed it slightly, placed it in a specific position, and sacrificed it to this strange spirit plant.

In the Netherworld Spirit Fields area, there are only two kinds of six-grade spirit plants that are still a long time away from maturity.

After absorbing the bones of several four-grade demon beasts, the Skeleton Demon View has been built into a two-layer skeleton base, and the bones of different sizes and thicknesses are entangled together in various ways to form an extremely strange and very coordinated skeleton base.

"There's an abrupt and harmonious beauty."

Lu Xuan left a comment and came to the six-rank ghost eater Evil Vine Lingzhi.

He deliberately took out a few powerful Yin Souls from the Soul Attracting Lamp of the Fourth Rank and placed them around the Ghost Eater Vine.

Sensing the appearance of a powerful yin ghost, the ghost-eating vine immediately reacted, and the branches shot out like sharp arrows, enveloping the evil ghost and devouring it greedily.

After Lu Xuan cultivated all the evil spirit plants in the underworld area, he returned to the cave.

Since there was only a little bit of Zhuji Dan and Cleansing Pill in his hand, the output of the light cluster was no longer enough to support the demand of the grocery store, so Lu Xuan allocated a little time to refining the pill.

His level of refining Zhuji Dan has reached the level of Dacheng, and the level of the Four-Grade Dust Cleansing Pill is also close to the level of Xiaocheng, and the rate of Chengdan is far higher than that of some alchemy masters, which can be regarded as a major means of absorbing gold at present.

"Although you can get a large number of spirit stones as long as you make a little move, the light group is still more cost-effective."

Lu Xuan sighed secretly.

Time passed, and in less than a month, after the Youquan Flower in the Netherworld, there was a Yin Crying Wood that was also a five-grade fully mature.

Lu Xuan stood expectantly in front of a pale spirit plant surrounded by resentment and ghosts, and carefully picked it out.

The mind is condensed on it.

[Yin Crying Wood, Five-Rank Spiritual Plant, feeds on resentful souls, there is Yin Wind Invasion in the process of growth, and it will affect the monk's physique in the long run, and the mature Yin Crying Wood is the best material for refining special magic weapons such as Ten Thousand Soul Flags, and can also be used to refine Five-Grade Soul Pills. 】

"The high-level Spirit Cultivation Light Troupe has harvested quite a few recently."

Lu Xuan looked at the slightly flickering white light cluster, sighed with emotion, and reached out to gently touch the surface of the light cluster.

The light cluster shattered silently like the moon in the water in the mirror, turning into sparkling points of light, and the points of light reconverged and turned into a drawing phantom, which instantly poured into Lu Xuan's body at lightning speed.

Immediately after, a thought flashed through his mind.

[Harvest a five-grade yin crying tree, and obtain a six-grade treasure ghost mourning map.] 】
