Everything that happened in the Black Mercury Cave naturally had little to do with Lu Xuan.
He and his incarnation Ling Gu left smoothly and returned to their respective caves.
"There are only gains at a time, no thrilling exploration."
Lu Xuan opened the Mysterious Crystal Array and entered the cave.
During this trip, he entered the hidden Dragon Cave alone due to the guidance of Dragon Ball.
The only ones he encountered were a few ferocious beasts from the deep sea, a lot of mutated Han Jade Chi, and the dragon spirit in the stone palace.
Among them, Han Yu Chi and Jing Po are very powerful, and ordinary monks in the middle stage of pill formation will definitely not be able to solve them as easily as he does.
The harvest is not small either.
The most valuable among them are the corpse of a seventh-grade dragon and three premature baby dragons.
One can be used to nourish and cultivate the Canglong Wood, and the other can bring Lu Xuan generous light group rewards.
In addition, many fresh corpses of Han Jade Chi and five dragon bones and grass spiritual seeds were also obtained.
"Those cold jade dragons can almost cultivate the blue dragon wood to maturity. Maybe they just need to use the dragon corpse to help them in the final stage of maturity."
Lu Xuan thought secretly in his heart.
"The corpses can be buried in the spiritual field area planted with Canglong wood and Hualong grass, gradually forming a treasure land of dragon energy, allowing them and the little dragons to grow better."
He went to the core spiritual field, planted five dragon bones grass inside, and buried the dragon corpse.
Finally, don't forget to put the three pale white spheres inside to be nourished by the dragon's air.
"We still need to widen the small lake, otherwise we won't be able to raise these three little dragon cubs."
He frowned slightly.
The small lake already contains the Lihuo Jiao, the Green-horned Dragon Carp and the Rock-shelled Turtle, and its size is already limited. If these three small dragons were added to the lake, they would probably not have enough room to stand up.
Lu Xuan flew to the small lake and used the master-level Earth Drawing Technique. With the confused expressions of several spiritual beasts, he expanded the area of the small lake several times.
After the trip to Black Mercury Cave, he returned to his identity as an ordinary psychic planter.
Cultivate spiritual plants and raise spiritual animals every day, and live a stable and fulfilling life.
A month later, I accidentally heard news about the Jiaolong Cave from an acquaintance of Master Jiedan.
According to legend, many monks poured into that cave, but they all found nothing. The treasures inside seemed to have been taken away by the few foundation-building monks who entered it first.
Unfortunately, after a few foundation-building monks escaped by chance, they never showed up again, leaving countless monks envious of their ability to monopolize rare treasures.
Lu Xuan could only keep smiling, and there was a hint of envy in his words.
Inside the spiritual field.
He walked slowly among the ridges and ditches of the spiritual fields, carefully nurturing countless spiritual plants.
During the cultivation period, I met the grass puppet who had been patrolling the spiritual field.
"You little guy, you work hard day after day, you're good."
Lu Xuan showed admiration on his face, sighed, and a wisp of green wood origin energy surged out from his fingertips, seeping into the gray and black tumors of the grass puppet.
The huge head of the Grass Puppet instantly turned green, spreading all the way down, dyeing the whole body a green color, revealing a rich vitality.
In his mental perception, this special puppet with extremely low intelligence conveyed a thought of gratitude to Lu Xuan.
"You have been with me the longest. I need to find an opportunity for you to improve again."
Lu Xuan sighed secretly in his heart, looking at the two arrow vines with various types of arrows hanging in front of him, a thought flashed across his mind.
"When the time is right, integrate the two-faced Holy Infant into your body."
An idea struck him and he remembered a treasure that had once grown from the Holy Infant fruit plant.
The double-faced holy infant is a special soul that can be integrated into a high-level puppet. Unfortunately, he did not master the method of refining the puppet, otherwise it would have been refined into the grass puppet's body.
After the grass puppet absorbed the Qingmu source energy, it continued to patrol the spiritual field with the arrow vine.
Lu Xuan continued to observe the growth status of many spiritual plants.
When I came to the sword grass area, I stood quietly next to the moving star sword grass, immersed in the meaning of the sword, feeling the movement of the sun, moon and stars, and gained enlightenment.
"It is indeed a sixth-grade sword grass. After studying it for so long, I finally gained some insights."
"Of course, the Transparent Sword Heart contributed a lot. Otherwise, with my talent in swordsmanship, it would be absolutely wishful thinking to understand the sword's intention."
Lu Xuan was satisfied and came to the Thousand Thunder Sword Grass Spirit Field area.
"Hey, three Thousand Thunder Sword Grasses are mature!"
He concentrated on the silver-white sword grass and was a little surprised to see the translucent progress bar below the sword grass.
The silver-white sword grass reaches up to the sky, and there are thousands of thunders surging on the sword, and the surrounding area is full of sharp sword intent.
He carefully pulled out three fourth-grade Thousand Thunder Sword Grasses.
[Thousand Thunder Sword Grass, a fourth-grade spiritual plant, is improved from ordinary second-grade sword grass stimulated by rich thunder energy and kendo treasures. It is a natural sword weapon that contains a large amount of thunder energy and has a miraculous effect on the enemy. 】
"It's equivalent to a fourth-grade flying sword, and it's of better quality. It should be able to sell for a good price in a grocery store."
Lu Xuan sighed and focused on the three white light groups that quietly emerged.
Reach out and touch the nearest one gently.
The light group shattered silently, turning into bright spots of light all over the sky.
Countless light spots were like subtle sword energy, quickly condensing into a slender river of light, and instantly poured into Lu Xuan's body.
Then, a thought flashed through his mind.
[Harvest a fourth-grade Thousand Thunder Sword Grass, and obtain the fifth-grade treasure Thunder Sword Gallbladder.]
Thoughts flashed across his mind, and a strange treasure appeared in front of him.
The treasure is like a small hedgehog, with countless slender silver-white thunder thorns extending out. The thunder thorns are hesitant and have a sharp sword intent.
There are countless silver-white lights as thin as hairs inside. Upon closer inspection, you find that the lights are actually a collection of sword intent.
Listening carefully, there was a slight thunder coming from the treasure, and the thunder swept across, as if injecting a righteous and domineering aura into Lu Xuan's body.
He concentrated on the treasure in front of him and instantly learned the detailed information about it.
[Thunder Sword Gallbladder, a fifth-grade treasure, can be used to temper the heart of swordsmanship with thunder energy after refining. Over time, it can slightly improve swordsmanship talent.]
"It is somewhat similar to the transparent sword heart that I obtained before."
"But the Transparent Sword Heart focuses more on techniques and can help me understand various sword techniques."
"This Thunder Sword Heart is slightly more focused on Dao, but the effect is not as significant as the Transparent Sword Heart."
Lu Xuan briefly compared the two kendo treasures and focused on the second white light group.
Even though I have touched countless light groups, I still have expectations in my heart.
I look forward to finding various magical high-level treasures inside.
The light ball shattered silently under his touch, turning into tiny points of light all over the sky.
Countless light points changed rapidly around him, condensing into thousands of slender little sword shadows, and instantly disappeared into his body.
At the same time, a thought flashed through Lu Xuan's mind.
[Harvest a fourth-grade Thousand Thunder Sword Grass and obtain a sixth-grade Thousand Thunder Sword Formation (1/18).]
"Um?"
As soon as the thought disappeared, Lu Xuan looked down at the silver flying sword in front of him, and countless question marks appeared in his mind.
