Ling Li first took the jade slip of the "Qing Jade Dan Sutra" obtained by the Poison Hand Doctor Saint from the Burning Heaven Secret Realm, and reached out with his divine sense to read the contents. In terms of content, this "Qingyu Dan Sutra" is similar to the "Qingying Dan Sutra" of Aoki Old Monster, and they all belong to the elixir skills of the Nirvana Realm, which are several grades worse than the "Zilang Treasure Urn", but there are several pill techniques and a few pill recipes that are slightly inspiring to Ling Li, and they are not very useful.

Ling Li quickly copied the content of the "Qing Yu Dan Sutra" in the sea of knowledge, and then handed the jade slip to Tuoba Ye, and then said: "This jade slip of the "Qing Yu Dan Sutra" can still be used twice, Brother Tuoba can use it to envelop two good Dan masters, which is of some use to the Tianying Gate." ”

Tuoba Ye was stunned, but he was not polite anymore, and carefully put away the jade jian: "Then thank you Brother Lishan." ”

Ling Li was not polite anymore, took the Immortal Crane Pill Furnace in his pocket, took the Immortal Beast Skin Book and Map, and then selected a few relatively rare ground-level spiritual materials on the shelf, and then signaled that he had finished choosing.

"This time as a brother, even if you take advantage of your brother." Tuoba Ye said a word, and then swept away the things in the secret room like a wind, and put them all into the storage ring. In general, in this secret room, the total value of the pill with source crystals is about five million lower grade source crystals, and the harvest this time is not small.

"Now, we should have left." Back in the hall, Ling Li groaned slightly. said to Tuoba Ye and Mao Zhang, "However, Ji Boyu of the Xuanji Sect will definitely not give up easily, there must be someone from them outside who is secretly watching, and now I am afraid that Ji Boyu has already gotten the news, and he is a little impatient to wait." ”

"What's that, Ji Boyu is a bird, we're not afraid of that kid!" Tuoba Ye said.

"More is better than less, it's daytime, it's too much movement, and then the entire Black Plains City will know that we have entered the cave of this poisonous hand doctor, and if we provoke the attention of the big guys, it will always be a little troublesome." Ling Li smiled.

Tuoba Ye thought for a while: "It's okay, let's wait here until the evening before going out." ”

The three of them couldn't cultivate in the stone room hall, so Tuoba Ye and Mao Zhang simply sorted out the harvest in the secret room, mainly the martial arts and jade slips. There are not a lot of martial arts and martial arts collected by the poisonous hand doctor Saint Sun Gaoli before his death, but this thing is not very useful to the three of them, but for the Heavenly Eagle Sect, maybe some exercises or martial arts are very suitable for the cultivation of disciples and others.

Ling Li returned to the secret room by himself, sat on a stone chair, and then took out the Immortal Crane Pill Furnace and put it on the table, studying it carefully.

The structure of the Dan furnace is like the veins in the human body, and the more advanced it is, the more complex its structure becomes. Ling Li's current use is the Qingying Dan Furnace used by the Aoki Monster back then, which is a top-level Earth-level Dan Furnace, with 286 source power channels and fire outlets. You must know that each fire outlet in the Dan furnace is engraved with a spirit array, and in order to control 286 spirit arrays at the same time, you need to have at least the soul power of the primary level of the Nirvana Realm.

Fortunately, Ling Li was already a twin soul body, and his spiritual power in the sea of consciousness was already strong, coupled with his cultivation in the Soul Forging Tower, he was now completely able to control the Qingying Pill Furnace, and he also seemed to be at ease.

After taking out the Immortal Crane Pill Furnace, Ling Li couldn't help but take a deep breath, and his mood fluctuated slightly.

The height of this Immortal Crane Pill Furnace is only less than three feet, the style is simple, the surface is glowing with bronze luster, and there are strange and mysterious cyan runes like hair, and the whole exudes an ancient and vast atmosphere. He is a person who knows the goods, and he knows that this Immortal Crane Dan furnace is mixed with a little Aoki Divine Copper to have such a color. In the Five Elements, Jin Ke Wood, and this Aoki Divine Copper comes from meteorites outside the sky, and is said to be produced in ancient Aoki, so it is a rare heaven-level material.

With this Aoki Divine Bronze alone, the grade of this Immortal Crane Pill Furnace will never be lower than the ground level.

On the surface of the Immortal Crane Dan Furnace, there was a dense text engraved with about three hundred words, similar to the words in the black animal skin book, but Ling Li didn't know these words at all, so naturally he couldn't know the meaning.

After Ling Li waited for his mood to calm down completely, he slowly infiltrated his divine sense into the inside of the Dan Furnace.

"Huh, 1024 fire vents? Heavenly Rank Dan Furnace! After probing his divine sense into the inside of the Immortal Crane Pill Furnace, Ling Li's face was suddenly shocked, and he almost didn't blurt out.

The Heavenly Rank Dan Furnace can be called an immortal weapon, and the immortal weapon is extremely rare in the entire Chiyan Continent, maybe only those super sects or hidden families can have so many things.

Ling Li is not very keen on immortal weapons, listening to what Gui Bo said, there should be a lot of immortal weapons in the Xuanchen Immortal Mansion, but unfortunately, with his current realm, he can't open the nine-story pagoda in the Xuanchen Immortal Mansion at all, even the first layer is just able to enter, and it is just a mecha maintenance and production workshop. The apprentice should be able to refine the immortal weapons below the middle grade, but it is a pity that Ling Li can't find enough Heaven Rank materials.

Ling Li calmed his breath and pressed his palms on the Dan Furnace, and a steady stream of fire attribute source qi entered into the Dan Furnace. In an instant, the real fire in the Dan furnace rose and burned brightly.

However, the formation pattern of the fire mouth inside the Dan furnace was very distinctive, and it was somewhat different from the formation system on the Chiyan Continent, and it was also different from the formation system that Li Shanqing said, which made Ling Li very interested in it.

1024 fire vents, 1024 formations, each formation has some differences due to different positions, Ling Li covered his divine sense on these formations, and slowly immersed himself in them. After he had sorted out all the principles of the 1,024 small formations, several hours had passed, and the sky outside the cave had gradually darkened.

In Heiyuan City, there are still a lot of strong people, if the news spreads, it is still a little dangerous for them to stay in this cave, so they have to leave quickly and return to Heiyuan City to wait for the Burning Sky Secret Realm to open soon.

Back in the hall of the stone chamber, Tuoba Ye and Mao Zhang also finished sorting out the martial arts collected in the Poison Hand Doctor Saint, and the two were examining those pills on a stone table, when they saw Ling Li coming out, Tuoba Ye told him that most of these pills were well preserved, most of them were sixth-order pills, and there were even a few bottles of seventh-order treasure pills, which were worth more than they had estimated before.

Tuoba Ye has gained a lot this time, and Ling Li's harvest of the Immortal Crane Pill Furnace is also worth the trip, and everyone is very satisfied. After briefly discussing some unexpected situations that could be encountered when leaving the cave, the three of them no longer hesitated, Ling Li led the way in front, and while collecting the array flags that had been arranged when they came, they quickly left the cave.

The three of them left the cliff and wanted to sneak out of the valley, but as soon as they entered the woods in the valley, they heard a loud rumbling sound behind them, and the earth shook violently. When they turned around, the cave in the middle of the cliff was cracked, presumably by the formation left by the original Poison Hand Holy Doctor, which destroyed the entire cave.

This is not a small movement.
