After Lu Ping practiced the Dan furnace simply, 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 in front of a futon next to the Dan furnace that was different from the surrounding ground.

Lu Ping stretched out his hand and pressed it, and the stone slab on the ground in the middle retracted to all sides, revealing an array disk, and in the center of the array disk was a blue fireball the size of an egg.

Lu Ping was overjoyed, this is the spark of the blue spirit fire of the Xuan Rank, this spark can be said to be the most precious collection of Sheng Tao monks, and it is naturally the biggest harvest of Lu Ping's trip.

This kind of spiritual fire is naturally generated between heaven and earth, and it is divided into the third order of heaven and earth according to the level of energy use, but the amount is not directly proportional to the level of energy use.

However, no matter what level of spiritual fire it is, it is extremely rare and hard to find. It can be said that half of Monk Sheng Tao's reputation as an alchemist comes from this Xuan-level spiritual fire.

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

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

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

At this time, Lu Ping had been a little numb by the successive harvest "blows", and he no longer had the ecstasy of each harvest before.

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

There is actually a small teleportation array disk embedded in the stone wall of the cave entrance.

In a large closed cave, suddenly a light 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 happy in his heart, it seemed that what Sheng Tao's predecessor said was not wrong.

Alchemist Sheng Tao accidentally found a miniature spiritual vein here, and Sheng Tao, who was overjoyed, decided to use this place as his cultivation base, he completely closed the cave, and used the spirit sealing array to imprison the spiritual energy emitted by the spiritual veins in the cave, and then built a cave on it, leaving a secret teleportation array connected to the cave. After that, Sheng Tao opened up a half-acre spiritual grass garden in the cave for his own alchemy and cultivation.

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

The stone walls of the cave are inlaid with glittering stones for lighting, and the water oozing from the stone walls drips onto the ground.

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

The Spirit Grass Garden is divided into three parts, the outermost part is the spirit grass that refines 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 spirit veins can only supply the spirit grass after being imprisoned, so the mature seeds fall on the ground and continue to grow, and these spirit grasses are already densely grown.

One layer inside is a variety of spirit grasses for refining hemolysis stage pills, and the pills in the hemolysis stage often require five hundred years of spirit grass refining, because Sheng Tao discovered this place more than a hundred years ago before he sat down, plus Sheng Tao's special spirit inducing technique was born, and most of the spirit grass inside was also mature.

Among the twenty-four kinds of spirit grasses that refine the Hemolysis Pill, there are actually eighteen kinds planted here, but the spirit grass that refines the Hemolysis Pill is obviously much more difficult to grow than other spirit grasses in the hemolysis period, and only five of the nearly fifty spirit grasses have reached the age of five hundred years, and the others are not yet mature.

Further inside are three Golden Pulp Grasses, which were cultivated by Sheng Tao, the master of the Golden Pulp Grass, and they were the main medicines of the Golden Pulp Pill in the refining and forging period recorded by Sheng Tao

The refining of elixirs in the forging pill period often requires more than a thousand years of spirit grass, and these three spirit grasses have only given birth to nearly five hundred years of medicinal age, which is far from meeting the requirements.

Below the Spirit Grass Garden is the miniature spiritual vein, the spiritual vein is a rarer thing than the spiritual stone mine, although it cannot provide spiritual stones like the spiritual stone mine, but it can continuously provide spiritual energy for the monks to cultivate, and there is no need to worry about the depletion of the spiritual vein, unless it is maliciously destroyed.

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

In order to prevent the Spirit Grass Garden from being discovered, Lu Ping collected all the mature spirit grasses in the Spirit Grass Garden, and an hour later, 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, and after thinking 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 mansion, erased all traces of himself, and calculated 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 it.

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

Just a while after Lu Ping returned to Huangli Island, several rays of light in the sky came out of the sky and landed on the islands and reefs, among which were Hu Lili and the other three were the three Hemolysis Stage Immortals on Xuanqi Island. If Lu Ping were to do it again, he would find that two of them were Liu Xianchang and Shang Xianchang, who had been sorry for him before.

Hu Lili and the three of them saw that the island was in a mess, and although they had lost hope for a long time, their faces still changed. The three immortal elders looked solemn, carefully inspected the surroundings of the island and reef, and carefully searched the nearby sea area with their divine sense, but finally found nothing.

Among the three, Liu Xian's long cultivation was the highest when he reached the seventh layer of the hemolysis stage, so he was the leader. Shang Xianchang looked at the two of them and asked first, "What does Senior Brother Liu think?"

Liu Xianchang pondered and said, "This sea snake should be cultivating the water system exercises, condensing the spirit Jiao bloodline, and cultivating should be in the middle stage of hemolysis." ”

The other immortal elder continued: "Yes, it's just that according to what Master Hu said, in the end, the Xuanling Sect disciple should use a rune treasure, and the strange thing is that even the worst forging pill real person condensed rune treasure should be severely damaged by this snake demon." ”

Shang Xianchang smiled and said: "That's right, I think it was this snake demon who was hit hard and went berserk, and destroyed this island and reef in a mess, so that we couldn't find any clues." ”

Liu Xianchang said solemnly: "It should be like this, after all, five Xuanling Sect disciples have died here, and we need to report the matter to Qu Zhenren to prepare early, in case the Xuanling Sect takes advantage of this matter to make trouble to this faction, not to mention that there is also the demon clan involved, I don't know if the Beihai Demon Clan did it intentionally." ”

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 elders leaving, they could only follow helplessly.
