Ling Li first took the jade slip of the "Qingyu Dan Sutra" obtained by the Poison-Handed Medical Saint from the Secret Realm of Burning Heaven, and poked out his spiritual sense to read the content. In terms of content, the "Qingyu Dan Sutra" is similar to the "Qingming Dan Sutra" by the old monster Qingmu, and they are both elixir skills in the Nirvana realm, which are several levels worse than the "Zilang Baolu". However, there are several elixir techniques and several elixir recipes that have slightly inspire Ling Li, and they are not very useful.

Ling Li quickly copied the content of the "Qingyu Dan Sutra" in the sea of ​​consciousness, and then handed the jade slip to Tuoba Ye, and then said: "This jade slip in the "Qingyu Dan Sutra" can be used twice. Brother Tuoba can use it to win over two good alchemists, which is of some use to the Tianying Sect."

Tuoba Ye was stunned for a moment, and did not hesitate anymore. He carefully put the jade slip away: "Then thank you brother Lishan."

Ling Li didn't hesitate anymore, so he took the immortal crane elixir furnace, took the immortal beast skin book and map, and then chose a few rare earth-level spiritual materials on the shelves, and then signaled that he had already chosen it.

"This time I took advantage of my brother." Tuoba Ye said, and then swept away the things in the secret room like a wind and clouds, and put them all into the storage ring. Calculation, the total value of the elixir with source crystal in this secret room is about five million low-grade source crystals, and the gains this time are quite large.

"Now, we should leave." Back at the hall, Ling Li pondered for a moment and said to Tuoba Ye and Mao Zhang, "However, Ji Boyu from Xuanji Sect will definitely not give up easily. There must be their people outside staring at him in secret, and now I'm afraid that Ji Boyu has already received the news and is a little impatient to wait."

"What's that? Ji Boyu is a bird. We are not afraid of that boy!" Tuoba Ye said.

"It's better to have less trouble than more. It's daytime now, and it's too much noise. By then, the entire Heiyuan City will know that we have entered the cave of the Vicious Medical Saint. If we attract the attention of the big shots, it will be a little trouble." Ling Li smiled.

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

The three of them were unable to practice in the stone room hall. Tuoba Ye and Mao Zhang simply sorted out their gains in the secret room, mainly martial arts and jade slips. The saint of the poisonous doctor Gao Li collected a lot of martial arts and martial arts during his lifetime, but this thing was not very useful to the three of them. However, for the Tianying Sect, some martial arts or martial arts may be very suitable for the practice of disciples and disciples.

Ling Li returned to the secret room by himself, sat on a stone chair, then took out the crane elixir stove and placed it on the table, and began to study it carefully.

The structure of the alchemy furnace is like the veins in the human body. The higher the level, the more complex the structure is. Ling Li is currently using the Qingming alchemy furnace used by the old monster Qingmu, which was a top-level earth-level alchemy furnace with 286 source power channels and fire outlets. You should know that each fire outlet in the alchemy furnace is carved with a spiritual array. To control 286 spiritual arrays at the same time, you need to have at least the soul power at the primary level of Nirvana Realm.

Fortunately, Ling Li is a twin soul body, and the spiritual power in the sea of ​​consciousness is already strong. In addition, his cultivation in the soul-forging tower is now fully able to control the Qingming Pill Furnace, and he seems to be at ease.

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

This crane elixir furnace is less than three feet high, with a simple style, with a bronze luster on the surface, and is covered with strange and mysterious green runes like hair, exuding an ancient and vast atmosphere. He is a person who knows the crane elixir furnace, which is so colored. In the five elements, gold overcomes wood, and this green wood divine copper comes from meteorites outside the sky. It is said that it is produced in ancient green wood, so it is a rare heavenly material.

With this Green Wood Divine Copper alone, the grade of this Crane Pill Furnace will never be lower than that of the Earth level.

On the surface of the crane elixir furnace, there is a dense text engraved with about 300 words, which is similar to the text in the black animal skin book. However, Ling Li did not recognize these words at all, so he naturally could not know the meaning.

After Ling Li waited for his mood to completely calm down, he slowly penetrated his spiritual consciousness into the pill furnace.

"Hey, 1024 fire mouth? Heavenly level elixir furnace!" After exploring his spiritual sense into the interior of the Crane Pill furnace, Ling Li suddenly looked shocked and almost blurted out.

The Heavenly Level Pill Furnace is a fairy weapon, and the fairy weapon is extremely rare even in the entire Red Flame Continent. Perhaps only in those super sects or hidden families can there be a few.

Ling Li was not very enthusiastic about immortal weapons. According to Gui Bo, there should be many immortal weapons in Xuanchen Immortal Palace. Unfortunately, with his current realm, he could not open the ninth-level pagoda in Xuanchen Immortal Palace. Even the first floor was just allowed to enter, and it was just a mecha maintenance and production workshop. The craftsmen should be able to refine medium-grade and below immortal weapons, but unfortunately Ling Li couldn't find enough heavenly materials.

Ling Li calmed down his energy and concentrated his mind. He pressed his palms on the alchemy furnace, and the continuous source of fire attributes was input into the alchemy furnace. In an instant, the real fire in the alchemy furnace rose and burned wildly.

However, the array pattern at the fire mouth inside the Dan Furnace is very distinctive, which is somewhat different from the formation system on the Chiyan Continent, and is also different from the formation system mentioned by Li Shanqing, which made Ling Li very interested.

There are 1024 fire outlets, 1024 array patterns, and each array pattern has some differences due to the different positions. Ling Li covered the spiritual consciousness on these array patterns and slowly immersed in it. After he made all the principles of these 1024 small array patterns clear, several hours had passed, and the sky outside the cave gradually became darker.

There are still many strong people in Heiyuan City. If the news spreads, it is still a bit dangerous for them to stay in this cave, so they have to leave quickly and return to Heiyuan City to wait for the Burning Heaven Secret Realm to be opened.

Back in the stone room, Tuoba Ye and Mao Zhang also sorted out the martial arts and martial arts collected by the Doctor Saint. They were inspecting the pills on a stone table. When Ling Li came out, Tuoba Ye told him that most of the pills were well preserved, mostly sixth-level elixirs, and even several bottles of seventh-level treasured pills, which were more valuable than they had previously estimated.

Tuoba Ye gained a lot this time, and Ling Li harvested the Crane Pill Furnace, which was worthwhile. Everyone was very satisfied. After briefly discussing some unexpected situations that could be encountered when leaving the cave, the three of them stopped hesitating. Ling Li led the way in front, while gathering the formation flags arranged when they came and quickly left the cave.

The three of them left the cliff and wanted to sneak out of the valley quietly, but as soon as they walked into the woods in the valley, they heard a rumbling sound coming from behind, and the earth trembled violently. They turned around and saw that the cave in the middle of the cliff collapsed and the ground was broken. It must have been the formation left by the Holy Doctor of the Poison Hand who had activated it himself, destroying the entire cave.
