During the war, there shouldn't have been such a long retreat time, but this war, which revealed a large number of strange residences, even those holy product eighth and ninth order powerhouses that should have appeared when the city defense was tight, there was no one who appeared, and the Earth Fire City could be said to have killed all the high-level powerhouses because of the sudden explosion, but after the Earth Fire City, there was never a single high-level powerhouse, which was wrong, and Han Fei also knew that although the explosion in the Earth Fire City was huge, the real damage caused was probably not much to say, as for the high-level powerhouses, there were probably not many people who really died。

But just like this, after the Earth Fire City, there was not even a single Rank 8 Rank enemy general who appeared, which definitely revealed weirdness.

And as time passed, Han Fei gradually discovered that after being attacked, those soldiers defending the city often did not care about the life and death of ordinary people, and even did not care about their own life or death, which caused an unwanted obstacle to the siege, and after careful study, Han Fei once again found that all the enemy troops defending the city were remnants and veterans, and it could be said that they had almost no combat effectiveness.

After knowing this, Han Fei's face was extremely solemn, the other party seemed to kill more in a way that was close to suicide, and he didn't seem to care about this city at all.

Uncanny!

Han Fei never knew what the other party's purpose was, and although he had discovered these suspicious points, he didn't know that there was any information about the soul, and the only person who knew this information had been immersed in various studies at the moment.

The front is slowly advancing.

Yan Danchen has been studying in retreat, because what he is most familiar with is the vitality of the pill, so its first pill is the pill for the treatment of injuries, but this pill is not the same as the pill made before, it used to condense the vitality in the pill by virtue of its own special features, this pill is valuable in the vitality in it, not the herbs in it, once there is no vitality in it, the so-called pill is just a dregs dumpling.

However, it is not easy to do this by not relying on oneself to solidify the vitality, but relying solely on the medicinal power, because the elixir that can have a healing effect has extremely high requirements in terms of vitality, and at the same time, in Yan Danchen's view, the value of such an elixir should be equivalent to the value of the medicinal effect, that is, to give full play to the medicinal power.

It is easy to refine an elixir with similar effects, but the difficult thing is to use extremely ordinary herbs to refine an elixir that can help cultivators recover from their injuries.

Under Yan Danchen's continuous efforts, combined with the content of this "Medicine Sutra", Yan Danchen made a rough classification of the pills, and divided them into four levels according to the current cultivation level, but until now, Yan Danchen still has not refined the pills that he is satisfied with.

Yan Danchen once again opened up a sealed space in the Hades Ring, and opened up a medicine field near the Nirvana Divine Tree in this space, where some low-level elixirs were planted.

Being able to think of this method is also due to Yan Danchen's inadvertent discovery that the elixir in the Hades ring has not withered, but still has the momentum to grow, plus there is already a Nirvana Divine Tree in this Hades ring that sounds very powerful but is still useless so far, Yan Danchen also has a little confidence in opening up in this Hades ring.

It's just that the space inside this Hades Ring is a dry world after all, even if this world has a glimmer of vitality because of the existence of the Nirvana Divine Tree, it can still only allow low-level elixirs to survive.

For the refining process of the elixir, Yan Danchen has faintly had a corresponding direction, but the suitable formula has not been found.

In fact, Yan Danchen already had a deep understanding of pharmacology, but there were still some discrepancies in the refining method of the elixir, and these slight differences also led to the fact that the effect of the ammunition could not be perfectly played.

The pharmacology in the "Book of Medicine" is to boil the medicinal soup by boiling, but after in-depth research, Yan Danchen found that this is too wasteful, and the medicinal soup is extremely inconvenient to carry, it must be condensed into a pill, and all the medicinal materials are completely utilized, removing impurities, refining medicinal power, and condensing into a pill.

To do this, there must be enough temperature, the little flame that boils the decoction is obviously not good, Yan Danchen's origin true fire temperature is enough, but there is nothing that can withstand the high temperature, which also makes Yan Danchen quite distressed, and finally found that small round tripod.

The temperature is enough, but there is still a huge problem with condensing into a pill, and the process is also very complicated, and the consumption is also very large, after researching the method that can become a pill, Yan Danchen decisively gave up the process of becoming a pill, as long as the pill liquid is refined, it will be passed.

But not all herbs can withstand the high temperature, so the temperature limit is also extremely high, requiring extremely high control ability and mental power, which has gradually mastered after Yan Danchen's many attempts, but there is another point, and the most important point, is Danfang.

Now Yan Danchen has tried thousands of pills, but these pills have never had Yan Danchen's attractive formula.

Maybe Yan Danchen was too demanding, or maybe the effect of the pill liquid was really not very good, and this first pill never condensed.

Moreover, the time spent refining the pill was also extremely long, and in half a year, Yan Danchen had tested it thousands of times.

For the goal, Yan Danchen never gave up, although there was no moment of pill that Yan Danchen wanted in the process, there were still several pills that entered Yan Danchen's eyes.

This first one is an elixir that Yan Danchen accidentally discovered during the development process and can replace diet.

This elixir is also strange to say, it was originally to stimulate the vitality in the elixir, but I don't know why, this stimulation made the vitality condense, and indirectly played the effect of continuously providing energy, after Yan Danchen discovered this and improved, the first Bigu Dan was born.

The effect of this elixir is exactly like its name, if you take one pill, you can go without eating for a month.

It's just that there are two elixirs in this Bigu Pill, and their value is far greater than that of the pill liquid made from ordinary herbs.

After discovering this direction, Yan Danchen didn't try to refine the elixir with all ordinary herbs, after all, this elixir sometimes has a decisive effect, if it is all ordinary herbs, this is really a little impossible.

After trying the elixir, Yan Danchen gradually discovered some mistakes in the "Book of Medicine".

After all, Hua Lao was not a cultivator, and his sensitivity to the medicinal effects of the elixir was not as good as that of a cultivator, let alone Yan Danchen.

After correcting some mistakes and supplementing these questions from the perspective of a cultivator, Yan Danchen's knowledge in pharmacology can be said to be gradually showing signs of surpassing Hua Lao to a certain extent.

But this is just a sign, if you want to really surpass Hua Lao, Yan Danchen can't do it without decades of hard work.

As time passed, another three months passed, and in these three months, Yan Danchen corrected the mistakes of those elixirs one by one, and at the same time discovered many new elixirs, and at the same time, the formula of the elixir was gradually perfected.

A month later, Yan Danchen had refined the first Soul Pill that satisfied him, completely without using his own life force.

Then, another month later, Yan Danchen refined the first pill that could improve his cultivation.

Yan Danchen named it Qingling Dan.

The pills that can be looked at by Yan Danchen are all extraordinary, the same as the previous Bigu Pill, it has an excellent effect, the Soul Pill, its healing effect is comparable to the original Soul Pill, and the Green Spirit Pill has an effect on all people below the Heavenly God Level, although the effect on the holy product is slightly insufficient, but the person of the Xuan product is the most suitable, and for the mortal product, the effect of Yan Danchen's pill is too domineering.

But Yan Danchen didn't think about using this Qingling Pill for the cultivation of mortal products, the appearance of this Qingling Pill was actually prepared for Xuanpin, to be precise, it was for those whose strength did not lie in cultivation, but in the aspect of mental power, such as Han Fei.
