Not long after, the Sword Sect set out to conquer the unknown cave heaven.

Lu Xuan stood at the highest point of the cave and looked up at the sky of the Sword Sect.

Under the cover of the Ten Directions of Destruction Sword Formation, countless huge sword energy either whistled by or flexibly wandered. Suddenly, a flying boat shaped like a giant sword flew past the sky.

Immediately afterwards, the second and third...

"There are twelve giant sword boats alone!"

Lu Xuan exclaimed in a low voice.

"There are no less than twenty Yuanying True Lords dispatched, more than two hundred Jiedan Zhenren, and more than a thousand foundation-building disciples from the outer sect."

"Such a huge momentum, I guess I can sweep the unknown cave sky back and forth several times."

"I wonder how many fellow disciples can get opportunities from the cave."

"Unlike me, I can only cheer for them, stay in the sect and collect all kinds of spiritual plants, and collect the light balls."

Lu Xuan thought in his heart.

After the expeditionary cultivators of the Sword Sect left, the sect fell into a rare quiet atmosphere.

There were many fewer fellow disciples of Huanzhen Jianfeng who often visited Lu Xuan Cave Palace.

Lu Xuan wished that this was the case, so he stayed in the cave to cultivate spiritual plants.

"There are two more fifth-grade sword grasses that are fully mature."

Among the only seven fifth-grade sword grasses left, one of the White Bone Killing Sword Grass and the Dividing Shadow Sword Grass is fully mature.

Lu Xuan picked it out of the spiritual soil respectively.

The two sword grasses are of good quality, with strong and pure sword intent, and are both high-quality natural sword weapons.

After packing up the two fifth-grade sword grasses, Lu Xuan's eyes fell on two white balls of light in each of the spiritual fields.

The sword energy in Lingtian is filled with the light energy, like a slender fish, passing through the light ball, forming a different kind of beauty.

Lu Xuan reached out and touched one of them gently.

The slight light spots in the sky soared into the sky, and instantly condensed into a slender river of light, rapidly sinking into his body.

[Harve a fifth-grade Spectral Escape Shadow Sword Grass, and obtain the sixth-grade treasure Yuanjing Sword Title.]

A thought flashed through my mind.

Immediately afterwards, a strange treasure appeared in front of Lu Xuan.

The treasure can be vaguely seen in the prototype of the flying sword, its whole body is crystal clear, with a faint spiritual light flowing on the surface, and the pure sword intent gushed out, and it seems that it can feel its slight breathing.

Lu Xuan flipped up and down, and his mind fell on the treasure.

Suddenly, detailed information about the treasure appeared in his consciousness.

[The Yuanjing Sword Body, a sixth-grade treasure, is condensed from a large number of sixth-grade rare spiritual ore, and is the prototype of the mid-level flying sword magic treasure. It has full spirituality and can be nourished in a short time and sacrificed to refine magic weapons. At the same time, its power is far better than that of the same-level flying sword.]

"Sixth-grade treasure, Yuanjing sword fetus."

Lu Xuan looked at the flying sword crystal in his hand that seemed to have not yet been opened, and was satisfied.

"It is extremely difficult to refine an ordinary sixth-grade flying sword into a middle-level magic weapon. It takes a lot of energy to cultivate and temper it. This Yuanjing sword body has its own spirituality and consumes much less time and energy than an ordinary flying sword. Its power is much stronger, and it can be regarded as the prototype of a natural magic weapon."

He thought to himself.

"For sword cultivators, the value of this Yuanjing sword body is far greater than that of ordinary sixth-grade flying swords. If they are placed in the grocery store, it will probably attract many fellow sword cultivators to rob them."

With a thought, the Yuanjing sword fetus was immersed in the Taochuang sac.

Come to the other side of the spiritual field, reach out and gently touch the second white light ball.

[Harve a fifth-grade white bone killing sword grass and obtain the sixth-grade treasure cave mysterious sword monument.]

Thought flashed by, and a strange stone tablet appeared in front of him.

The stone tablet is about three feet long, with mottled surface, revealing the feeling of ancient and long years. The front has the word "Dongxuan" and one stroke and one stroke enters the monument three points, like a sword mark.

On the back is an invisible small sword standing deep in the stone tablet, floating and sinking, appearing and disappearing, and seemingly able to burst out the shocking sword energy at any time.

"The second cave sword monument is a pretty good sixth-grade sword treasure."

A smile appeared on Lu Xuan's face.

This Cave Xuan Sword Monument is a token of the Sword Sect. It is closely related to the Supreme Cave Xuan Sword Domain in the Sect and is the key to entering the Sword Domain.

At the same time, the Dongxuan Sword Monument is of great benefit to sword cultivators. Practicing near the stone monument can achieve twice the result with half the effort. The countless sword intents inside will also affect the surrounding areas, causing it to slowly form a sword intent treasure land.

Lu Xuan harvested a piece from the light ball many years ago and placed it in the sword grass spirit field area of ​​the Thunder Mars Cave. It played a lot of role in improving the Thousand Thunder Sword Grass and the Small Cave Xuan Sword Gourd.

"However, the origin of this cave mysterious sword monument is unknown. If it is discovered, it is difficult to explain. It is best not to take it out in the Sword Sect."

"If you have the right opportunity, see if you can enter the Dongxuan Sword Domain with this."

Lu Xuan put away the Dongxuan Sword Monument.

"The rewards of the light balls produced by the mature fifth-grade sword grass are pretty good, and they are rare among the same-level treasures and are of great value."

Lu Xuan patrols the field and carefully observe the remaining five fifth-grade sword grasses.

As for other high-level sword grass, except for the sixth-grade star-changing sword grass, it is far from maturity.

"It's almost time to condense the seven primordial spirits."

He carefully cultivated it and entered the courtyard given by the real sword master in Xinjian Lake.

In the yard, Yangxuan sword sheath was inserted obliquely into the spiritual soil, and countless pure sword intents around it wrapped it firmly.

Lu Xuan picked up the ancient sword sheath and shook it gently. The silver-white sword grass spirit seeds slid out easily.

Compared with the last time, the vitality revealed by the spiritual seed is obviously stronger.

"It seems that the sword energy treasure land in Xinjian Lake is quite effective."

Lu Xuan murmured in a low voice, and he couldn't help but feel more anticipated.

"More than 20 spiritual seeds should be successful in stimulation and induction, right?"

Because he mastered the method of condensed seeds of Thousand Thunder Sword Grass, he was extremely willing to invest more than twenty spiritual seeds at a time.

His mind moved, and a long crack in the spiritual soil of Thunder Sword Grass lingering with thunder.

The mind is condensed on it.

【Thousand Thunder Sword Grass, Fourth-grade Spiritual Plant…】

"It's still the same as before."

Lu Xuancha looked at the spiritual seeds, and there was no difference in the information that appeared in the sea of ​​consciousness, which meant that there was no abnormality in the spiritual seeds.

His expression was as normal, and there was no fluctuation in his heart.

The fourth-grade sword grass is more than ten times more difficult to improve it into the fifth grade than the third-grade sword grass.

But he still has full confidence.

"Ordinary planters want to improve the new variety of plantings, after inducing and stimulating the plantings, they need to be cultivated and matured."

"During the cultivation process, we need to slowly find out the most suitable cultivation method. At the same time, it will take ten or even decades to know whether the mutagenesis is successful."

"And I just need to use all kinds of spirits to get its detailed information. Just a round of induction can save you a lot of time and energy, not to mention that multiple experiments are required during the improvement process, and the savings are immeasurable."

"So, I alone can match countless sect forces in improving the spirit seeds."

Lu Xuan sighed at the special ability he had and continued to observe the remaining silver-white spirit seeds.

"Um?"

He exclaimed lightly.

The thoughts in my mind finally had a subtle difference.

[Thousand Thunder Sword Grass, a fourth-grade mutated spiritual plant, is induced under the dual stimulation of the sword energy treasure land and the sword Tao treasure. During the cultivation process, it must be nourished by the thunder sword energy.]

[After the spiritual plant matures, it is a natural sword weapon, which contains the mysterious thunder spirit breath, which can easily stimulate powerful thunder sword energy, and its power is close to the fifth-grade flying sword.]

"I finally got the mutational spirit seed!"

Lu Xuan felt a strong joy in his heart and couldn't help but sigh.
Chapter completed!
