It's a pity that there is no Blue Blood Qinglan in it, otherwise refining a furnace of Blue Blood Washing Alchemy Pill will be enough for Nian Bifeng to break through to the Heavenly Level, and the Blue Blood Washing Alchemy Pill should also be of great benefit to Gu Youqing, and it may be able to stimulate the possibility of Gu Youqing's improvement again.

"I didn't get the Blue Blood Blue Orchid, but the auxiliary medicinal materials are quite complete, do you try to use other medicinal materials to synthesize it, can it replace the medicinal effect of the Blue Blood Blue Orchid?"

Lin Yu sat cross-legged in the Juyuan Array in the cultivation room, pinching his chin and thinking about it, the main medicine of the three-grade spirit pill was not that it could not be synthesized, but it was basically hopeless if his ability was synthesized before, but now it is very different.

With the help of a wisp of divine sense, coupled with the top-level fire yuan power after the refining and transformation of the Fire Spirit Fruit, Lin Yu could really give it a try.

In the future, when his Yuan Power is completely transformed into spiritual power, and his Divine Soul is getting stronger and stronger, and he can hold more Divine Consciousness, maybe the main medicine of the four and five grades of the elixir can also be tried to synthesize, even if the efficacy of the medicine will decrease, at least the medicinal materials used for synthesis are easy to find.

"Let's give it a try, anyway, the number of auxiliary spirit grass is quite sufficient, don't worry about it will be insufficient, even if you fail a few times, it doesn't matter. ”

After Lin Yu made up his mind, he waved his hand and took out a large amount of spirit grass and levitated it around his body.

The synthesis of the main medicine also requires the use of Dao God Tianding, but this process is much easier than alchemy, and it can also be regarded as an opportunity to warm up God Tianding, so Lin Yu naturally has nothing to hesitate about.

The first attempt was not successful, and before even a third of the time was reached, the spirit grass used for synthesis turned into useless dregs.

Lin Yu cleaned up these medicinal residues from the Divine Heaven Ding, shook his head and said to himself: "Sure enough, it is not so easy to synthesize a main medicine like the Blue Blood Qinglan, but fortunately, I already have some eyebrows, and it should be much better next time." ”

While speaking, Lin Yu had already started the second synthesis, and this time it was much smoother, and the progress of the synthesis was advanced to about two-thirds before it was declared a failure due to a small mistake.

After these two experiences, Lin Yu's confidence became more and more sufficient, and the third time was almost successful, but he regrettably failed at the last moment.

It has reached the level of completion of ninety percent, Lin Yu thinks that it will definitely be completed next time, who knows that failure will still appear in this position.

"Hmm, what's going on?Why did there be such a mistake twice in a row?" Lin Yu didn't continue for the fifth time, but frowned to find the reason.

"All the steps are correct, the technique is perfect, and the timing and heat are very accurate, so what went wrong?"

It's a pity that Lin Lao is concentrating on refining and absorbing the ancient giant crocodile's divine soul at this moment, and Lin Yu doesn't want to disturb him, so he can only continue to explore by himself.

"Blue Blood Blue Orchid, Blue Blood Blue Orchid, although the final synthetic medicinal materials will not appear like Blue Blood Blue Orchid, but the inner quality is quite close, do you want to do this?"

Lin Yu raised his eyebrows slightly, and remembered a technique he had heard of a long time ago, but he had never used it before, so he could try it this time.

The fifth synthesis began step by step, everything went in an orderly manner as before, and when it came to the critical point of two consecutive failures in the end, Lin Yu's eyes widened, he gently bit the tip of his tongue, and squirted out a mouthful of essence blood on the cloud of medicinal liquid.

The flames in the Shentian Ding swelled suddenly, wrapping the synthetic medicinal liquid, and a faint fragrance wafted out, this time the synthetic main medicine actually had some visions from the time of alchemy.

Lin Yu's face turned slightly pale, and then returned to normal, seeing the medicinal liquid that exuded a faint halo in the Divine Heaven Ding, Lin Yu shook his head with a smile and said: "It's really dangerous, it turns out that the synthetic medicinal liquid of the Blue Blood Qinglan really wants to use human essence blood as the final fusion agent." ”

The use of essence blood as a fusion agent for the synthesis of medicinal liquids is a method that Lin Yu heard about when he was on Earth, but this method is basically not used, because the synthetic medicinal liquid is always impossible to compare with the natural main medicine, and the level of the synthetic medicinal liquid generally does not exceed the level of the alchemist.

For low-level alchemists, the main medicine that can be synthesized is naturally low-level spirit grass, and high-level alchemists have a small chance of synthesizing high-level spirit grass.

In addition, a person's use of essence blood will consume their own life force, a high-level alchemist, in order to synthesize a high-grade spirit grass, is likely to put his life on the line and not succeed, such investment and harvest, naturally make this method regarded as chicken ribs by many alchemists.

In the past, Lin Yu would never use this method to synthesize elixir, because the elixir he could synthesize was basically available for purchase, and a fool would not do it if he exchanged his life for this elixir.

However, it is different now, because of the life sharing contract with the ancient giant crocodile, the last thing Lin Yu is afraid of is squandering his vitality, it is not a small consumption for Lin Yu, and if he puts it on the ancient giant crocodile, he can't even reach the level of being bitten by a mosquito, and he can recover in the blink of an eye.

"It seems like I'm a little sorry for the ancient crocodile man. Lin Yu touched his chin and chuckled: "I'm sorry, I'm sorry, brother doesn't care." ”

There is such a golden mountain-like existence, it is stupid not to know how to use it, in order to live up to the life sharing contract specially given to him by the ancient giant crocodile brother, Lin Yu feels that he must carry it forward.

Of course, the synthetic medicinal liquid is never the right way, and it is impossible for Lin Yu to use such a method to refine the pill all the time, and this method is only used for emergency relief in situations like the current one.

After having the main medicine, it would be much more convenient to refine the Blue Blood Wash Alchemy, and Lin Yu had already had the experience of refining the Blue Blood Wash Alchemy Pill once, and this time he was even more proficient.

Three furnaces of pills in a row, under the precise control of the divine consciousness and the refining of the top-level fire element power, twelve full pills were refined.

Thirty-six blue blood washing alchemy, put in the ancient small rivers and lakes, is definitely an amazing wealth, if people know its efficacy, the major forces will definitely fight for it.

The only regret is that none of the thirty-six Blue Blood Washing Alchemy Pills are of top-grade quality, because the main medicine is synthetic, and there are inherent defects, which is also a matter of no choice.

However, the twelve mid-grade pills with two Dan halos and the twenty-four lower-grade pills with one Dan halo had already made Lin Yu quite satisfied.
