After obtaining the five-rank cloud bamboo arrow formation formation, Lu Xuan couldn't hold back the curiosity in his heart and came to the outside of the cave.

The surging spiritual power poured into the array, and a handle array flag flew to different positions on the edge of the cave, and the spirit pattern on the surface of the flag swam and disappeared in an instant.

A thick sea of clouds soon appeared outside the cave, and between the churning of the sea of clouds, strange bamboos that towered into the clouds loomed, and there was a faint commotion sound.

"The double protection of the five-grade formation ensures that no evil demon insects invade the cave mansion and damage the spirit plant."

A satisfied smile appeared on Lu Xuan's face.

The last arrow vine, he saw that it was not long before it matured, so he simply used Aoki source qi to ripen it.

Now he has accumulated a lot of Naling Grass Beads in his hands, which can replenish Aoki's source qi in time, and he is full of confidence in using it.

After picking out the arrow vine, Lu Xuan gently touched the white light cluster that quietly emerged.

Countless points of light turned into a small white arrow phantom, which instantly poured into his body.

[Harvest a four-grade mutant arrow vine and obtain a five-grade treasure nail head arrow. 】

The thought flashed, and a small black arrow appeared in his hand.

There is a faint black gas lingering on the surface of the small arrow, like a slender black snake swimming slowly, and the arrow seems to be nailed to a translucent face, and the facial features of the face are blurred, and it is not real.

His mind was condensed on this small black arrow, and a message appeared in his mind.

[Nailhead Arrow, a five-grade treasure, contains a powerful curse power, and when used, you can imagine the target's appearance, breath, etc., and directly act on its soul. 】

[Monks below the realm of Yudan die on the spot, and monks in the realm of Jiedan regard factors such as cultivation, soul strength, and treasures, and have a certain probability of death. 】

"It's another five-grade nail-headed arrow!"

The treasure unleashed by the last arrow vine satisfied Lu Xuan's heart.

"Cursed treasures, you don't have to fight people head-on, for him who has been shrinking in the cave, it is the treasure of the Yin people."

At this point, all four arrow vines that had been scavenged from the newly opened blessed land had matured.

Lu Xuan harvested two five-grade nail-headed arrows from the light cluster, a four-grade magic weapon split electric pantograph, and a five-grade formation cloud bamboo arrow array, each of which was quite good.

With a thought in his mind, the grass puppet that was patrolling the Lingtian walked on two slender grass legs and rushed towards Lu Xuan's side.

On its slender arm woven from gray grass, a blue and black vine was entwined, and arrows of different sizes and shapes extended from the vine, adding a bit of ferocity to the originally silly-looking grass puppet.

"Here, these three arrow vines will also be handed over to you, if you encounter any demon beast monks who try to sneak into the cave in the future, you will use these four arrow vines to shoot them to death."

Lu Xuan instructed the grass puppet.

Although the grass puppet was not very intelligent, this simple order was still clearly understood, and the gray grass head, which was a little deformed, nodded emphatically.

The body shot out three gray grasses, pulling three vines, wrapping around the body, large and small arrows bulging, looking somewhat similar to hedgehogs.

"Haha, the strongest straw man."

Lu Xuan couldn't help but laugh, and threw a Naling Grass Bead to the grass puppet, letting it continue to patrol the Spirit Field.

The arrow vines wrapped around the upper body of the grass puppet make the two slender legs look even more weird, and they look weak.

But if it was seen by the foundation monks, envy and jealousy would definitely arise in their hearts.

A grass spirit puppet has four special vines equivalent to a four-grade magic weapon, what else does this cultivation mean?!

After harvesting the arrow vines, many spiritual plants in the cave entered the stage of steady growth.

After a period of time, Lu Xuan planted more than fifty Tibetan Yuan Grass Spirits and began to cultivate.

Half a year has passed in the blink of an eye.

In the spiritual field, it is lush and full of life.

Lu Xuan stood in the ditch of the spiritual field, inspecting the detailed state of the spiritual plants one by one, ensuring that each spiritual plant could be fully nourished.

In the past six months, he didn't explore the secret realm or anything, and spent most of his time in the cave.

Occasionally go out, either to pick up the star tower to supplement some cultivation needs, or to get together with a few familiar monks in the Thunder Mars Cave, during which I also went to the Thunder Sea twice, but basically in the peripheral area activities, after collecting some spiritual thunder, I was content to quit.

The few thunder spiritual plants in the spiritual field currently have a large demand for spiritual thunder, and some common spiritual thunder can meet their current growth needs, so they don't need to spend too much thought for the time being.

He came to the Sword Grass Spirit Field area, standing in front of the White Bone Killing Sword Grass shaped like a slender bone sword, and his mind sank into the sword intent around the Sword Grass.

"Boom".

An awe-inspiring sword aura shot out from his fingertips, stirring the surrounding sword intent, and suddenly, the killing intent was monstrous, making Lu Xuan feel like he was on the battlefield.

His surroundings were densely packed with enemies, with stumps and severed arms everywhere, and dark red blood flowing, staining the whole world red.

Lu Xuanyu used the killing sword qi in the sky, like mowing grass, and easily killed the surrounding enemies one by one.

Thousands of times of experience in the sword, let him slowly have a kind of understanding in his heart, Tongming sword heart helped him summarize, and the sword qi flew faintly revealing a special meaning.

"I finally have a preliminary understanding of the corresponding sword technique."

Lu Xuan opened his eyes, and the corners of his mouth rose.

The five-grade white bone killing sword grass was conceived by the sword pool of the Heavenly Sword Sect at the beginning, and there was no corresponding cultivation sword technique.

After planting the spirit seed, Lu Xuan could only use the killing sword intent contained in the spirit seed to cultivate the sword grass from scratch.

Fortunately, he had obtained the treasure of Tongming Sword Heart before, so that he had no less understanding than those swordsmanship geniuses in the way of the sword, so he was able to find a relatively complete set of sword skills.

"White Bone Killing Sword Grass, that sword technique is called "Killing Sword Sutra"."

Lu Xuan whispered in his heart.

The current mastery of this sword scripture is probably in the fourth-grade stage, if you want to successfully cultivate this five-grade sword grass, you still need to continue to comprehend and study, and when it is perfected into a five-grade sword scripture, then the white bone killing sword grass can mature smoothly.

As for the other Light Splitting Shadow Sword Grass, due to its relatively late cultivation, the difficulty of Light Splitting Sword Intent comprehension was slightly higher than that of Killing Sword Intent, so there was only one approximate prototype.

However, with the assistance of Tongming Sword Heart and his exquisite control of Sword Grass, Lu Xuan was confident that he could comprehend the corresponding sword technique.

"When these ordinary sword grasses are ripe, you can condense some sword grass spirit seeds, and then try to improve them and find a way to get a higher grade sword grass."

Lu Xuan looked at no less than twenty second-grade sword grasses next to him, and thought secretly.

When he first moved out of the Heavenly Sword Sect, he deliberately went to the Sword Hall to apply for some ordinary sword grass spirit seeds.

This kind of sword grass has no difficulty in applying, and it is easy to get a lot of spirit seeds, plus the grade is low, only the simple sharp nature, and there is a lot of room for improvement.

In addition, he has mastered the method of condensing the seeds of the second-grade sword grass, and he can obtain the spirit seeds in batches, so he can try to induce improvements.
