According to the records, this burning spirit has existed for millions of years!

Legend has it that the Burning Spirit Han Yan was an ancient powerful Dan Immortal, and the Dan Furnace used was transformed by fire!

After this power ascended to the immortal realm, he left the Dan furnace and some treasures. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 After tens of thousands of years, this powerful treasure appeared, attracting many strong people to fight for it, and as a result, the treasure was divided up, and the Dan furnace was also destroyed in the struggle of several powerful people.

And some of the furnace fire that leaked out of the Dan furnace became the "Burning Spirit Cold Flame" that has been passed down to this day!"

As for the Chang Ling, it is the Chang Ling Spirit Grass and some tiny spirit insects, which have evolved over hundreds of thousands of years after being contaminated with a trace of cold and flame aura!

"Dan Immortal, Immortal Realm?" Seeing this, Lu Yu couldn't help but close the book and looked up at the sky.

At this moment, several streams of light flew out of the center of the lake and quickly came to him.

"This fellow Daoist, to fish for Chang Ling here, you need to pay one hundred Zhongpin Spirit Stones every day!" led by an old man in the late stage of the patriarch, he said to Lu Yu.

Lu Yu nodded, this point was also mentioned at the beginning of this Changling Treasure Book.

After the formation of the Burning Spirit Cold Flame, it has also gone through countless battles, and the current power of the Flame is much weaker than it was at the beginning, but it is still controlled by the Holy Realm specially sent by the Changtan Kingdom.

As for Chang Ling, it is open to outsiders, but for fishing here, you have to pay a hundred spirit stones to Ava City every day.

took out three hundred medium-grade spirit stones, threw them to the old man, and bought three days of fishing.

The old man put away the spirit stone, and then smiled at Lu Yu and said, "You can catch Chang Ling at most an inch here." If you feel that the location here is not good, you can go to the sky above the center of the lake. In addition, if the Taoist friend feels that he is strong, he can also enter the bottom of the lake through the secret passage. At the bottom of the lake, there is a foot of Chang Ling!"

"How does the center of the lake collect spirit stones, and how much does it cost to enter the bottom of the lake?" Lu Yu asked lightly.

The old man smiled and said, "Five hundred medium-grade spirit stones in the center of the lake are one day." To enter the bottom of the lake, you need five thousand medium-grade spirit stones, but there is no time limit!"

Lu Yu nodded and did not speak.

The old man turned around and led the people away, and flew to the other one, who had just come to the real human realm by the lake.

Lu Yu shook his head, this old man is also a treacherous man, he didn't mention the difference between various places before collecting the spirit stones, and he didn't say until he took the spirit stones!

After checking the Chang Ling Treasure Book for a while, Lu Yu took out the jade box containing the five Chang Ling.

In this jade box, there is a little lake water, and it is the five Chang Ling, but they are all still alive.

According to the Chang Ling Treasure Book, once this Chang Ling leaves the waters of the Cold Flame Lake, it will die quickly. After death, this spirit will become another poison that cannot be absorbed and refined.

And if Chang Ling dies in the lake, it will merge into the cold lake and become the nourishment for the growth of other Chang Ling!

Carefully wrapped a piece of Chang Ling with soul power, and Lu Yu sensed it carefully.

The spirit also seemed to know that death was near, and twisted and struggled desperately in the soul power.

With the quality of Lu Yu's soul power, it took more than a dozen breaths to sense the extremely faint and faint flame aura in this Chang Ling's body.

According to the method contained in the treasure book, grab the Chang Ling with soul power, then put it in the palm of your hand, and slowly inject Dan power to refine.

A rather rich spiritual power poured into the palm of the hand and slowly poured into the dantian space.

After trying it, this spiritual power is still the most fully absorbed by the Fire Yuan Dan.

After more than a dozen breaths, this Chang spirit was completely refined, and in addition to the spiritual power, there was still a trace of fiery aura in the dantian space, which was almost impossible to sense.

Lu Yu sent it into the place where the water system was void and the fire was fireless, but the water system fire did not react at all, and this fiery breath was burned into nothingness!

Lu Yu sighed in his heart, such a spirit insect, let alone fuse the water system Danhuo, and even sense the cold and flame attributes in it, it can't be done!

Looking at the remaining four Chang Spirits, Lu Yu simply refined them together.

It is worth mentioning that although the Chang Ling, which is more than an inch, still can't make the water system Danhuo sense the cold and flame attributes, the fire aura produced is more than three times stronger than that under the inch!

After refining the five Chang Ling, he took out the fishing note and looked at it carefully.

After a moment of reading, he lifted the pole, and then condensed a few drops of soul blood and injected them into the hollow pole.

The soul blood condensed into a thin line of blood, quickly reaching the top of the rod, and then entering the fishing line, extending towards the lake.

This fishing line extends extremely long, reaching dozens of feet below the surface of the lake.

Closing his eyes and concentrating, Lu Yu sensed the changes in the silver needle below, and at the same time, his divine sense covered the surroundings of the lakeside, listening to the conversations of the many cultivators who were fishing for the Chang Spirit.

After more than three hours, hundreds of drops of soul blood were used in a row, and finally a Chang spirit less than half an inch long was attracted by the soul blood and swam over from a distance!

As soon as Lu Yu's soul power moved, the silver needle flew upside down with a "snort" and came to the side of the Chang spirit.

The Chang Ling was slightly frightened, but sensing the soul blood breath on the silver needle, he still opened his small mouthparts and bit the tip of the silver needle in one bite!

Lu Yu injected soul blood into the rod again, and then with a light lift, the fishing line quickly shrank into the rod, and immediately lifted the spirit out of the water!

After a casual glance, he put away the spirit and refined it.

After refining, Lu Yu directly got up and put away the pole and flew along the lakeside to the southeast.

With his powerful soul power, it took so long to catch one, and if he continued like this, if he stayed here for a thousand years, he was afraid that he would not be able to make up the number of cold flames that would make the water system Void Pill Fire fuse and mutate!

After personal experiments, Lu Yu felt that if he dived to the bottom of the lake and used the Demon Breaking Spear to release soul power to capture, it would definitely be hundreds of times faster than staying here!

In addition, he also wanted to see what the fiery aura contained in the Qi Xu Chang Spirit was.

Flying around the shore of the lake for nearly a hundred miles, you came to a huge cave.

According to the information he gathered, this cave was an entrance to the bottom of the cold lake.

It is said that there are three more similar caves.

At this moment, outside this cave, there are more than a dozen Ancestor Realms waiting to enter.

Lu Yu looked at it, and when he entered this cave, he didn't check his identity, but only needed to pay five thousand medium-grade spirit stones.

In addition, most of the dozen or so people waiting in line are in the middle and late stages of the patriarch, and from the perspective of superficial cultivation, the cultivation of the first order of his patriarch is the weakest one.

It wasn't long before it was Lu Yu's turn, and after also paying five thousand medium-grade spirit stones, he followed behind the dozen or so Ancestor Realm and flew towards the depths of the cave.
