In the spiritual field, Lu Xuan looked at a hideous vine like a huge python in front of him, and carefully picked it out of the spiritual soil.

The vine was the three-grade Jiao vine brought over from the Heavenly Sword Sect when it moved away, and a long time ago, it also opened a one-step five-grade body refining technique from its light cluster, the upper part of the "Taixu Transformation Dragon Chapter", Lu Xuan has been thinking about the remaining part.

"It's a pity, it's just an ordinary three-grade treasure."

After harvesting the light group, Lu Xuan looked at the reward in his hand and said with a slightly disappointed expression.

However, he can also understand, after all, Jiao Teng is only a three-grade spirit plant, when he planted it, he was already in the realm of foundation building, and when he harvested the light group, he was even more cultivated, and downgrading cultivation and harvesting would naturally affect the quality of the treasure.

"It seems that if you want to get the follow-up exercises of the 'Tai Void Dragon Chapter', you have to improve the Jiao Teng into a better grade spirit plant, or obtain it from a similar spirit plant light group."

He thought to himself.

He was quick to accept that he didn't get the reward he expected.

"Anyway, there is a five-grade Vajra Bodhi, looking at its efficacy, there is a high probability that it can open at least a five-grade or even six-grade refining treasure."

In addition to the three-grade Jiao vine, the spiritual plants that were brought over at the beginning also included the fourth-grade Earth Fire Heart Lotus, the Five Elements Fruit, etc., and the condensation method of the Earth Fire Heart Lotus and the Five Elements Fruit.

Therefore, after the spirit plant matured, he did not rush to pick and harvest the light cluster, but used it all to condense the seeds.

"After the number of spirit seeds such as the Five Elements Fruit is sufficient, you can plant it on a large scale, and at the same time as mass production, you can also try to improve it."

After the spirit plant grade reached the fifth grade, it was extremely difficult to obtain, so Lu Xuan saw if he could get one or two pieces through improved induction.

The Earth Fire Heart Lotus and the Five Elements Fruit, whether it was the spirit fruit they bore or the light group reward, were quite good in his impression, so he specially got the condensation method of these two spirit plants.

According to the method, he guided the grass and tree aura and essence in these two mature spirit plants through different means, condensed together, and slowly waited for the spirit seed to be condensed.

"Lu Daoyou can be in the cave mansion?"

When he was inspecting the Lingtian to inspect the Lingzhi, a cold female voice came from outside the house.

A silver silk nun appeared in Lu Xuan's mind, the female cultivator's name was Ye Xuanyin, and she had come to the cave mansion to congratulate her when she was promoted to Jiedan, and she had a relationship with him.

"Ye Daoyou, Lu is here."

His figure flashed and he came to the outside of the cave.

"I don't know what Ye Daoyou is about?"

Lu Xuan looked at the female cultivator with a warm smile on his face.

"I came here today to send you an invitation to Lu Daoyou."

"Invitation?"

Lu Xuan asked suspiciously.

"Lu Daoyou has been cultivating spiritual plants in the cave, and he may not know much about the big and small things that happened in the Tianxing Cave."

"A while ago, the Xing Xing envoy in the Black Mercury Cave successfully broke through to the late stage of the Jiedan, and wanted to invite the Zhenren who stayed in the Tianxing Cave to participate in the celebration banquet, so he specially asked me to come over and inform Lu Daoyou."

Ye Xuanyin said, and a strange talisman appeared in his hand.

The talisman was dark black and had no fixed form, like water droplets flowing slowly, and a slight rattling sound could be faintly heard.

"Black Mercury Cave Xing Xing Xing ......"

Lu Xuan said in a low voice, he occasionally met with nearby monks to communicate, and heard the name of the Xing Xing envoy from them, but he didn't have the opportunity to see it.

"Okay, Lu will definitely go to the appointment on time."

The late stage monk of Yudan, and at the same time the high-level invitation of the Tianxing Cave, it was naturally difficult for him to refuse, plus he was just going to a banquet, there was no risk, so Lu Xuan agreed casually.

Moreover, there must have been a lot of Jiedan monks gathered at the banquet, and he just took this opportunity to get acquainted with more, maybe one day he would be able to get one or two high-level spirit seeds from a certain Jiedan real person.

"The banquet is in three days, and then I will come over and invite Lu Daoyou to go with you."

Ye Xuanyin said with a smile.

"I'm sorry to trouble Ye Daoyou."

Lu Xuan gladly accepted.

……

The boundless waves were surging, and the deep black water was as far as the eye could see, as if the soul of the monk could be swallowed into it.

"Lu Daoyou, this is the first time I've come to Black Mercury Cave?"

Above the black water, Ye Xuanyin and Lu Xuan each controlled the flying sword and swept by at great speed.

"That's right, I have been in the Thunder Mars Cave for a few years, and most of the time I have stayed in the cave to cultivate spiritual plants, and only occasionally go to the Star Picking Tower."

Lu Xuan replied truthfully.

"Eighteen Star Caves, each Star Cave has its own peculiarities, the most famous thing in the Thunder Mars Cave is naturally the boundless Thunder Sea, which is rich in all kinds of spiritual thunder and even divine thunder."

Ye Xuanyin's head full of silver threads danced wildly in the air, and from time to time there were subtle thunderbolts appearing at the tips of his hair.

"As for the Black Mercury Cave, it is famous in the Liyang Realm because of all kinds of spiritual liquids, if Lu Daoyou is interested, you can bring some back to the cave, many spiritual liquids are conducive to the growth of spiritual plants."

Lu Xuan nodded hurriedly, feeling a little interested in the Black Mercury Cave in his heart.

"There are many islands scattered in the Black Mercury Cave, and the Qi cultivators live on the islands, and most of the foundation building or knotting monks are in the black water."

"There are many remnants of ancient times in the depths of this ocean, but most of those places are extremely dangerous, and even if you are a real person, you can't guarantee that you will be able to escape with your whole body."

"Prohibitions, sea beasts, evil cults lurking in the black water, evil cultivators, etc., are all mysterious and powerful."

Ye Xuanyin gave Lu Xuan a detailed introduction to the information of the Black Mercury Cave, and when he passed by a certain secret realm, he would simply say a few words, so that Lu Xuan knew a lot.

"Huh?"

When passing through a sea area, Lu Xuan's figure was stunned, his brows furrowed slightly, and then he returned to normal.

"What, Lu Daoyou has found something?"

Ye Xuanyin asked curiously.

"No, it's just that I've practiced a strange art, and I occasionally feel it in my heart."

"Ye Daoyou, do you know what is strange about this sea area?"

Lu Xuan said calmly.

"It's not very clear where this sea area is, but it is rumored that a seventh-grade strength xenomorph dragon appeared hundreds of years ago, but no monk has seen it since then."

"There are several secret realms nearby, but they have been explored by the monks in the Black Mercury Cave."

Ye Xuanyin did not doubt him, and said to Lu Xuan.

"I see, maybe it's just that there is something familiar in a secret realm, which makes Lu accidentally aware of it."

Lu Xuan nodded and said casually.

Just now, when passing through this sea area, his spiritual sense noticed a slight movement in the gluttonous insect sac hidden in his waist, and when he looked closely, it was the six-grade treasure obtained from the dragon skeleton grass light group, the dragon ball.

The beads trembled slightly in the sac, as if something was attracting it in the sea below.

"Could it be that there is a cave of alien beasts and dragons in the sea below, or is it a related treasure?"

Lu Xuan thought secretly in his heart.

He firmly remembered the scene around the sea area, followed Ye Xuanyin as usual, and rushed towards the cave mansion of the Xing Xing envoy.
