There are not many varieties of spiritual plants in the jade book. There are about fifty kinds of third-grade plants, and the number of fourth-grade plants is less than half, with only more than twenty kinds.
However, they are all relatively rare species in the cultivation world, so they can only be exchanged for sword seals.
Lu Xuan did a rough scan and found that the difficulty of planting third- and fourth-grade spiritual plants was much higher than that of first- and second-grade spiritual plants.
Various conditions need to be met. For spiritual energy alone, the concentration and purity requirements of the spiritual energy are not the same level. Many spiritual plants even require a special spiritual environment.
In addition, there are strange conditions in terms of spiritual soil, cultivation methods, etc.
"Junior brother Lu, do you plan to plant fourth-grade spiritual plants?"
The old farmer monk standing aside saw that Lu Xuan's eyes had been lingering on the jade book about fourth-grade spiritual plants, and asked incredulously.
"Just looking at it, with my current achievements in spiritual planting, I still can't cultivate a fourth-grade spiritual plant."
"So I just need to make preparations first and slowly accumulate the conditions to cultivate fourth-grade spiritual plants."
At first glance, the spiritual plant seems to be made up of the bodies of many weird insects. It is weird and harmonious, and has a strange beauty.
Lu Xuan said with a smile, his tone indifferent, as if he had no intention of planting the mysterious insect vine immediately.
Lu Xuan thought to himself, his eyes focused on the strange-shaped mysterious insect vine.
Lu Xuan nodded and read through it from beginning to end, gradually eliminating the bright patterns.
"Senior brother, how many sword seals are needed for this mysterious insect vine?"
Lu Xuan opened the wooden box and saw a dried spiritual seed the size of an egg inside.
Lu Xuan played with Erxiao for a while, then came to the spiritual field and couldn't wait to take out the wooden box.
"Thank you, senior brother, for reminding me."
The young falcon and the cloud-walking lynx still greeted us warmly.
The old farmer monk informed Lu Xuan about the Earth Fire Heart Lotus, which he controlled.
"It seems that those spirit cranes have reached a consensus, and they can have sex for nothing in the future."
"It is very difficult to cultivate the Fire Heart Lotus here. It is said that it needs to be planted in extremely hot magma. In addition, there are other planting conditions. Even the Foundation Architect Uncle cannot easily plant it successfully."
He took out the black insect vine and put it into the round hole.
He continued to read, and his eyes stopped on a strange-looking spiritual plant.
[During cultivation, it is in a symbiotic state with certain insects. The insects attach themselves to the Mysterious Insect Vine and provide growth nutrients for the Mysterious Insect Vine, while the Mysterious Insect Vine secretes special spiritual substances to promote the growth of the evil insects. 】
"It seems that we need to find some demonic insects that can shed their skins, place the eggs on the black insect vines to hatch them, and let them grow together."
"There are quite a lot of these kinds of monsters, such as cicadas, praying mantises, locusts, etc. There are also many records of related monsters in the "Insect Classic"."
His mind was focused on the mysterious insect vine spiritual seeds in the spiritual soil.
"Only the Mysterious Insect Vine seems to be easier to grow. I have the "Insect Classic" in my hand, and I have a deep understanding of demonic insects. I can cultivate corresponding insects according to the needs of the Mysterious Insect Vine."
"Fourth Grade Earth Fire Heart Lotus..."
Lu Xuan said casually.
After hearing that it needed to be planted in hot magma, Lu Xuan's interest suddenly dropped by half. With the current conditions in his cave, it was still unable to meet the growth requirements of the Earth Fire Heart Lotus.
【Teng Teng, I like little bugs the most.】
"Junior Brother Lu, have you thought clearly? The conditions for cultivating the Mysterious Insect Vine can be said to be very complicated."
"The cave environment is still not enough. The growth conditions of most fourth-grade spiritual plants cannot be met."
The surface of the spiritual species is uneven, and the colors and shapes of each part are different, like a mixture of many insect eggs, and you can feel the rich vitality inside.
"It's okay. I can slowly explore and experiment. As for monsters and insects, I can also collect them bit by bit."
Back in the cave, the spirit crane that carried Lu Xuan still refused in every possible way and was determined not to pay Lu Xuan any reward. Lu Xuan couldn't stand it and had to give up.
Although the shape of the Mysterious Insect Vine is a bit weird, it is nothing compared to the underworld spiritual plants such as the Thorn Bones and the Hundred-Eyed Creepy Wood in Jianmen Town.
"Junior Brother Lu, take it carefully."
There are more than twenty kinds of fourth-grade spiritual plants on the jade book, and some of the patterns are in a dim state. This means that although Sinong Palace can condense the corresponding spiritual seeds, it will take a certain amount of time, and the corresponding fourth-grade spiritual seeds cannot be provided immediately.
Lu Xuan couldn't help but smile, opened the formation, and after the white mist dissipated, he pushed open the courtyard door.
In an instant, a thought flashed through his mind.
However, he also knew that the spiritual seeds in the sect had already reached the internal price. Although he was reluctant to part with them, he still honestly took out a sufficient number of sword seals and handed them to the old farmer monk.
Thinking of this, he no longer hesitated and pointed at the pattern floating above the jade album.
[When the demonic insect matures, it breaks free from the body of the mysterious insect vine, and its body remains on the mysterious insect vine, becoming part of the spiritual plant.]
The second-grade sword grass, dark marrow mushroom, Qing Miao Ling tea and other rewards are already quite good, and the fourth-grade mysterious insect vine naturally makes Lu Xuan look forward to it even more.
Seeing that Lu Xuan insisted on exchanging the Mysterious Insect Vine Spirit Seed, the old farmer monk did not try to dissuade him and quickly took out an exquisite wooden box from the inner hall.
"The demonic insects and the mysterious insect vines grow together. Doesn't that mean that I don't need to raise the demonic insects? When they mature, they can directly receive the light group reward?"
"Thank you, senior brother."
"This is the Mysterious Insect Vine, a fourth-grade spiritual plant. It seems to be closely related to various monsters and insects. I don't know the details."
"It's a little expensive..."
Lu Xuan put the mysterious insect vine spiritual seed into the storage bag and said goodbye to the old farmer monk.
"If you are a fourth-grade spiritual species, you will need a lot of sword seals."
[Mysterious Insect Vine is a fourth-grade spiritual plant. When mature, it can increase the probability of demon insects being promoted to fifth-grade, and can also refine certain high-grade elixirs. 】
The old farmer monk reminded me kindly.
He found a blank area and used the Earth Drawing Technique. In an instant, the spiritual soil quietly changed, and a round hole slightly larger than an egg appeared on the ground.
Lu Xuan secretly sighed in his heart. He remembered that when he redeemed the third-grade sword-raising gourd spiritual seed, he spent ninety sword seals. Now, the fourth-grade mysterious insect vine spiritual seed actually requires more than two hundred sword seals.
On the jade album, a fiery red lotus flower slowly rotates. The lotus rhizome is light red and seems to be composed of countless irregular red crystals. The leaves are fiery red, and red magma seems to be slowly flowing inside the leaf veins.
"The mysterious insect vine spiritual seed requires two hundred and forty sword seals."
The old peasant monk replied.
"We can only wait until it matures and get good light group rewards."
The old farmer monk continued.
Immediately, he controlled the spiritual soil and buried the mysterious insect vine spiritual seed in the spiritual soil just right.
Lu Xuan had a sudden thought, and he didn't expect that choosing this mysterious insect vine would have such a special effect.
Now he does not have corresponding insect eggs on his body, so he can only use the Spiritual Rain Technique to maintain the vitality of the Black Insect Vine spiritual seeds.
If you want to promote growth, you need to parasitize insect eggs on spiritual seeds so that they can grow together.
