After Lu Ping simply refined the pill furnace, he immediately received the newly obtained storage bag.

Lu Ping walked around the alchemy room a few more times, as if looking for something, and finally found a stone that was different from the surrounding ground in front of a futon next to the alchemy furnace.

Lu Ping stretched out his hand and pressed it, and the stone slab on the ground in the middle retracted to the surroundings, revealing an array with an egg-sized blue fireball in the center of the array.

Lu Ping was overjoyed, this was the spark of the blue spirit fire of the Xuanjie, this spark could be said to be the most precious collection of Monk Sheng Tao, and it was naturally Lu Ping's biggest gain from this trip.

This kind of spiritual fire is naturally generated between heaven and earth, and is divided into the three levels of heaven and earth according to the level of energy use, but the amount of the number is not directly proportional to the level of energy use, maybe there are a few more spiritual fires in this cultivation realm level than the mysterious level.

However, no matter which level of spiritual fire it is, it is extremely rare and hard to find. It can be said that half of the reputation of Sheng Tao Monk Alchemist's fame comes from this mysterious level spiritual fire.

This kind of heaven and earth spiritual fire spiritual fire can be used for alchemy, naturally it can be used to refine weapons, but due to the scarcity of spiritual fire, the vast majority of alchemists and refiners are refined with the true fire condensed by their own mana, although the effect is not much different, but a lot of cultivation time is wasted, which is a contradiction that all alchemists and refiners face.

The array plate under the blue spirit fire is called the Burning Spirit Formation, and by embedding the spirit stone in it, the blue spirit fire can be triggered to refine it. At this time, the spirit stone above had exhausted its spiritual power after hundreds of years and turned into powder.

Lu Ping sealed the spiritual fire and placed it in the jade bottle, and then received it in the storage bag along with the array plate.

At this time, Lu Ping was already a little numb from the "blows" of the continuous harvest, and he no longer had the ecstasy of each harvest before.

Lu Ping returned to the cave entrance where he had just entered the cave before, and placed a few spirit stones in a few inconspicuous depressions on the stone wall in front of the cave entrance, and then played a set of discoveries, and suddenly the spirit stone on the stone wall flashed, and Lu Ping disappeared.

There was actually a small teleportation array plate embedded in the stone wall at the entrance of the cave.

In a large closed cave, a light suddenly flashed, and Lu Ping appeared in this cave.

As soon as Lu Ping appeared in the cave, he felt a faint aura surrounding him, Lu Ping was overjoyed, it seemed that Senior Sheng Tao was right.

He completely closed the cave and used the spirit sealing array to imprison the spiritual energy emitted by the spiritual vein in the cave, and then built a cave on it, leaving a secret teleportation array connected to the cave. After that, Sheng Tao opened a half-acre spiritual grass garden in the cave for his alchemy and cultivation.

Sheng Tao has been sitting in it for more than a hundred years, and he doesn't know how the spiritual grass he planted in it has grown.

The stone walls of the cave are inlaid with glitter stones for illumination, and the water that seeps out of the stone walls drips on the ground.

Lu Ping took a few steps forward, and a lush spiritual grass garden finally appeared in front of Lu Ping's eyes.

The spiritual grass garden is divided into three parts, the outermost is the spiritual grass that refined the elixir of the blood refining period, most of them have already matured, because no one takes care of them, and the spiritual energy in the spiritual vein can only supply the spiritual grass for the growth of the spiritual grass after being imprisoned, so the mature seeds fall to the ground and continue to grow, and these spiritual grasses are already densely grown.

The inner layer is various spiritual herbs for refining hemolytic period elixirs, and the hemolytic period elixirs often require five hundred years of spiritual herb refining, because Sheng Tao discovered this place more than a hundred years ago before he sat down, and with Sheng Tao's special spiritual aphrodisiac to spawn it, most of the spiritual herbs inside were also mature.

Among them, the twenty-four kinds of spiritual herbs for refining the Hemolysis Pill, there are actually eighteen kinds planted here, but the spiritual grasses for refining the Hemolysis Pill are obviously much more difficult to grow than other hemolytic period spiritual grasses, only five of the nearly fifty spiritual herbs have reached the age of five hundred years, and the others are not yet mature.

Further inside were three golden marrow grasses, which were cultivated with great effort by the Shi Shi Sheng Tao, and were the main medicines of the golden marrow pill that Sheng Tao recorded in the refining and forging period of the elixir

The refining of elixirs in the forging period often requires spiritual herbs that are more than a thousand years old, these three spiritual herbs have only given birth to nearly five hundred years of medicinal age, and they are far from meeting the requirements.

Although it cannot provide spirit stones to the spirit stone mine like the spirit stone mine, it can continuously provide spiritual energy for monks to cultivate, and there is no need to worry about the depletion of the spiritual vein, unless it is maliciously destroyed.

Moreover, spiritual veins can be cultivated and grown, for example, the spiritual veins on True Spirit Island were only medium-sized spiritual veins before, and after tens of thousands of years of careful cultivation by the True Spirit Sect, they are now a large spiritual vein.

In order to prevent the spiritual grass garden from being discovered, Lu Ping collected all the mature spiritual grasses in the spiritual grass garden, and after an hour, the teleportation array on the stone wall flashed, and Lu Ping appeared at the door of the cave again.

Lu Ping put his hand on his chin and groped for a while, he began to use spells to bombard the islands and reefs indiscriminately, and the ravaged islands and reefs were in a mess again, and then Lu Ping collapsed the entire cave house, erasing all traces about himself, and calculating the time, if Hu Lili and others reported the things on the islands and reefs, there would almost be monks from Xuanqi Island to check.

Lu Ping released his airship and flew towards Huangli Island in the north.

Just after Lu Ping returned to Huangli Island for a while, several rays of light from the sky cut through the sky and landed on the islands and reefs, including Hu Lili and the others, and the other three were the three hemolytic immortal leaders on Xuanqi Island. If Lu Ping were again, he would find that two of them were Liu Xianchang and Shang Xianchang who had been sad for him before.

Hu Lili and the three of them saw that the island was in a mess, and although they had no hope for a long time, their expressions changed. The three immortal chiefs looked solemn, carefully examined the surroundings of the island and reef, and carefully searched the nearby sea area with their divine senses, and finally found nothing.

Among the three, Liu Xianchang had the highest cultivation level to reach the seventh layer of the hemolysis period, so he was the leader. Shang Xianchang looked at the two of them and first asked: "What does Senior Brother Liu think?"

Liu Xianchang pondered for a moment and said: "This sea snake should be cultivating water-based techniques, condensing the spirit dragon's bloodline, and the cultivation should be in the middle stage of hemolysis."

Another Immortal Master continued: "Yes, but according to Master Hu's nephew, in the end, the Xuanling Sect disciples should undoubtedly use talismans, and the strange thing is that even the worst talisman-forging real person condensed Fu treasures should also inflict heavy damage on this snake demon."

Shang Xianchang smiled and said: "That's right, I think it was this snake demon who was hit hard that went crazy and destroyed this island and reef in a mess, making it impossible for us to find any clues."

Liu Xianchang said solemnly: "It should be like this, after all, there are five disciples of the Xuanling Sect dead here, and I need to report the matter to Qu Zhenren as soon as possible, in case the Xuanling Sect uses this matter to attack this faction, not to mention that there are demon clans involved, and I don't know if it was intentional from the Beihai Demon Clan."

The other two also agreed with Liu Xianchang's opinion, so they got up and flew towards Xuanqi Island. Hu Lili and the three of them didn't say a word from beginning to end, and when they saw the three immortal leaders leaving, they could only follow helplessly.
