Ye Yun didn't know that he didn't want to pay attention to Han Feng, but Han Feng had already included him in his must-kill list, and after he went back, he began to tell his subordinates to target Ye Yun.

As the foundation of the Canaan Academy's Fire Tower, the Falling Heart Flame can be said to be the foundation of the Canaan Academy, and it stands to reason that it is impossible for the Canaan Academy to agree to exchange for it, but Ye Yun knows that this Falling Heart Flame is actually not only one, but two, although one has only been born for a long time, but what Ye Yun needs to fuse the different fire is its characteristics, and there is not much difference between the one that has just been born and the one that has been born for a long time.

Since there are two Falling Heart Flames, as long as Ye Yun can come up with enough things to make them excited, there will definitely be no problem in exchanging one of them, and in the Douqi Continent, the most important thing is naturally the Douqi cheats, fighting skills, and high-grade elixirs.

Ye Yun doesn't have a powerful fighting spirit cheats, he doesn't have a powerful fighting skills, what he exchanged with Xiao Yan before was actually not a fighting skill, but a sword skill, although it can be urged with the same fighting energy, but it is indispensable, and the same thing is not so precious to take it out again, therefore, Ye Yun's choice now is only the elixir.

In fact, Ye Yun's alchemy is not very high, and the alchemy level of this world is probably in the range of seven or eight grades, but it is enough, and he is not short of pills, but now there is a very serious problem, although he is not short of pills, but he is very short of elixirs for alchemy, plus most of his pills are obtained from the Zhuxian world, and a small part is obtained from the magic mobile phone world, and the medicinal materials of the two worlds are not necessarily available in this world, so Ye Yun is a little difficult.

After rummaging through the boxes and cabinets for a long time, Ye Yun really found something that was very suitable for exchanging for the Fallen Heart Flame, the elixir of immortality obtained from the magic mobile phone world.

He had used this thing in the Celestial Traveling World, but after that he had thrown it into some unknown corner of the human seed bag, because his Ten Thousand Worlds Treasure Book was only a cultivation book that went straight to the Holy Realm, so immortality was only a matter of time before he was born; It's still early for his parents and family, and he doesn't need it, so he didn't think about it for a while, and it wasn't until this rummaging through the cabinets that he remembered that he still had this thing.

Life is a precious thing, and some people are even willing to give all their possessions in order to live a few more years; He is not precious if he says that he is not precious, in some worlds, after the strength reaches a certain level, a nap in the afternoon may be thousands of years away.

In this world, even if you have cultivated to the highest level of Dou Di, you can only live a few years longer than others, and your life span still has an end, and one immortal pill can increase your lifespan by 10,000 years, which is undoubtedly full of irresistible temptations for this world where no one lives forever.

Of course, 10,000 years was a bit too long, so Ye Yun found some ordinary pills to strengthen the body, and then took out an elixir, first divided it into two halves with sword qi, took back half of them, and used the remaining half as a medicine guide, mixed evenly with the ordinary pills for fifty people, and refined them into pills again.

Half a day later, Ye Yun took out the pills in the Dan furnace three times, the first time he took out was to extend his life for a hundred years, and it was also the most, there were twenty grains, the second time he took out only six pills for three hundred years of life, and the third time he took out only two pills for five hundred years.

It stands to reason that a pill of immortality can prolong life for 10,000 years, and half of it should be able to prolong life for 5,000 years without losing the medicinal effect, but the total amount of all life extensions after this half refining is only 4,008, which is 200 less than the total of 5,000, but after all, this has been refined, although it has not destroyed the medicinal properties in it, but the medicinal effect will be more or less lost.

Although it is two hundred years less than taking it directly, Ye Yun doesn't need this thing in the first place, and he also has the pill for refining the Immortal Pill, if he really wants to refine it, he can find a doomsday world to extract the energy of the earth's core, so Ye Yun is not distressed at all, but although the pill has been concocted, it is useless to find someone to experiment.

Anyway, there are a lot of pills, and Ye Yun is not afraid of wasting them, so he went directly to the "flea market" of Canaan Academy and bought a low-level demonic beast and an ordinary pheasant to come back to test the medicine, and the flea market of Canaan Academy is actually not as unbearable as in the play, although there are almost nothing that can make Ye Yun look at it, but there are still no things such as "chicken wings" and "low-level demonic beasts of cats".

The low-level magical beast that Ye Yun bought back was a lark, this kind of lark was only a little larger than an ordinary sparrow, and its appearance was similar to that of a sparrow, but there were some white cloud patterns on the edge of the wings, and it was precisely because of this that it was called a lark.

This lark doesn't look at it as small, but its flight speed is not slow, and ordinary fighting spirits may not be able to catch up with it, so the lark is widely used for communication, but although the lark is a magical beast, its lifespan is only ten years, the lark in front of Ye Yun is a lark that has been eliminated, full of twilight, and there are no more months to live, it should be the old man of Canaan Academy who wants to use it to pit newcomers, but it just meets Ye Yun's conditions.

As for the other pheasant, that pheasant was used by Ye Yun to see if ordinary animals could withstand the medicinal power of the elixir, if even the pheasant could withstand it, then the person would naturally be able to bear it, and only if the pheasant could withstand the medicinal power, the experiment could continue.

The pheasant that Ye Yun bought back without how smart he didn't know that it had become a guinea pig, no, it was an experimental chicken, and it was already happily pecking at the grain in the cage, and then, Ye Yun threw the pill the size of a mung bean into the cage.

The pheasant thought it was just an ordinary grain, and as soon as he lowered his head, he pecked at the lightly fragrant elixir, swallowed it directly, and then continued to peck at other grains.

Ye Yun saw that the pheasant and pheasant had eaten the pill, and immediately put his spiritual power on the pheasant's body, carefully observing the changes in its body, and in Ye Yun's observation of spiritual power, it took less than half a minute for the pheasant to swallow the pill, and a stream of medicinal power poured out of its body, penetrating into every cell in its body, so that its cells remained in a peak state at all times, of course, in this process, those medicinal powers were also constantly consumed, according to Ye Yun's estimates, it would take about a hundred years for this power to be completely consumed.

Ye Yun knew that his elixir was successful, but this pheasant was just an ordinary pheasant, and he didn't know how effective this thing would be on the Demon Beast or the person who had cultivated the Dou Qi, but this pheasant was no problem, and there should be no problem with the Demon Beast and the person who had cultivated the Dou Qi.

To be on the safe side, Ye Yun still gave the lark a pill, and the result made Ye Yun very satisfied, the lark regained its youth and was let go by Ye Yun and the pheasant.
