The so-called fusion is to completely integrate the liquids after refining different medicinal materials.

Although this process may sound simple, it is the most difficult and the most important step in the entire refining process.

The Qi Replenishing Pill that Ye Dong has refined now is the most basic pill, and the medicinal materials are also the most common, so their fusion is relatively simple.

However, when it comes to refining high-grade pills, the medicinal materials will have their own five element attributes, and some special materials will be added, such as demon pills, and even more powerful alchemists can condense the formation in the medicinal materials, so as to improve the medicinal effect of the medicinal materials, and the fusion process will be very complicated.

At the same time, fusion also requires a lot of support from Reiki, after all, the most common method to integrate different medicinal materials is to forcibly fuse with Reiki.

And sometimes, refining an elixir may take months or even years, and for such a long time, it is necessary to keep the input of the aura and cannot be stopped, so some alchemists will find some assistants, and several people take turns to maintain the input of the aura.

For Ye Dong, even if everything else is a problem, the aura is definitely not a problem, the penetration of the seven acupuncture points plus the dantian, the amount of aura in the body is almost comparable to that of a master who has just entered the realm of the earth.

Ye Dong took out the Xuan-level five-grade snake tripod, and Yao Shan also issued a series of instructions.

"Because your flame can't get out of your body yet, you can only put your palm under the snake and start heating the furnace. ”

In the past, when the Purple Flame Dragon Fire was a small flame, Ye Dong was able to shoot it out from between his fingers, but if he refined the medicine, he had to let the flame leave his body and continue to burn, which was what Ye Dong couldn't do at present.

"If you look closely at the inside of the snake ding, you will find that there is actually a dark grid inside, which is specially set for different medicinal materials, each medicinal material has a different melting point, and it is naturally convenient to burn it when put into a different dark grid. ”

"The temperature is enough, put in the medicinal juice, close the mouth of the ding, and let the spiritual sense observe the situation inside the ding through the contact between the purple flame dragon fire and the snake ding. ”

Although Ye Dong has the conditions, his head is also smart, and his aura is sufficient, after all, this is his first time refining medicine, so he can't help but be a little in a hurry, but fortunately, there are no mistakes, and he finally completed all the actions under Yao Shan's guidance.

Next, Ye Dong tried to let the spiritual sense observe the inside of the Ding through the snake ding.

If the spiritual sense can be released, then naturally there will be no need for such trouble, just like Yao Shan that day, even if it is separated by a certain distance, he can easily perceive the situation in the Ding.

Under the cover of Ye Dong's spiritual sense, he gradually entered the snake ding.

The liquid of the three medicinal herbs, driven by the heat and heat of the flames, slowly suspended in the air, kept tumbling, and made a sizzling sound.

Because of the first refining, Ye Dong didn't dare to put the flame temperature too high, but constantly adjusted the temperature according to the melting point of the four-leaf flower, so as to ensure that the three medicinal juices could be fused together, and they would not be directly evaporated into gas by the high temperature.

Gradually, the three medicinal juices had been fused together, and the volume had been reduced by at least half compared to the original, and they were hugged into a circle, Ye Dong knew that the pill was about to be successfully refined, because the basic shape had come out.

Yao Shan had also been using his spiritual sense to check the situation in the Ding Furnace, and at this time he spoke: "Yes, the Dan Fetus has appeared, and it is about to be finally formed, if you want to improve the attributes of your Pill this time, then add a drop of blood water in the sea of blood." ”

The last time Yao Shan was refining the Qi Replenishing Pill, he asked Ye Dong for a drop of blood water from the sea of blood at the last moment, so that the final Qi Replenishing Pill was all of the highest grade, and now when he heard that Yao Shan wanted to add blood water by himself, Ye Dong couldn't help but ask: "Old Yao, what can the blood water in the sea of blood improve the attributes of the pill?"

Yao Shan's face became heavy and said: "This is called blood sacrifice, blood, it is the essence of the life of any living being! When refining medicine or refining weapons, adding blood can increase the spirituality of the elixir or magic weapon, and the sea of blood in the blood prison is completely formed by the blood of countless people, and among these dead people, there are countless masters, and their blood has completely fused together to form a sea of blood after I don't know how many years of the Dao. ”

"Therefore, the strength of the aura contained in each drop of blood in the sea of blood is unimaginable, whether it is refining medicine or refining weapons, if you can add a drop of blood of the sea of blood, then you can greatly improve the grade of the pill or dust weapon!"

"Young Master, you are above refining medicine, any condition is extraordinary, but what is really enough to make all alchemists envious is because you have the entire blood prison, the sea of blood is boundless, and those precious blood are inexhaustible for you, so this is also doomed, no matter whether you become an alchemist or a refiner, the things refined by your hands will definitely be of extremely high grade!"

Ye Dong didn't know what to say for a while, although he could always see the sea of blood, but he always thought that it was only because a huge amount of blood was mixed in the ocean that the sea of blood would be formed, but now he knew about it.

It turned out that it was a real sea of blood at all!

How many lives do you have to die, how much blood does it take to gather into an endless sea of blood?

Ye Dong didn't dare to think about it further.

Silently took out a drop of blood from the sea of blood, opened the mouth, and threw the blood into it.

Suddenly, the entire Ding Furnace was immediately filled with a powerful spiritual aura, and the liquid that had condensed into a circle, after being integrated into this drop of blood, immediately accelerated and tumbled, absorbing all the spiritual energy into it.

"Next, don't worry, slowly cool down the temperature, let the liquid finally condense into a solid elixir, and the refining will be completed!"

The last process may be difficult for others, but for Ye Dong, who has been able to accurately control his aura, it is not too difficult.

Finally, Ye Dong opened the Dingkou, first a strange fragrance wafted out, and then a white round elixir rushed out directly, fortunately, Ye Dong reacted quickly enough, with a little finger, a stream of aura shot out, forming a net in the air, blocking the pill, and wrapping it and sending it to Ye Dong's hands.

Ye Dong extinguished the flames, looking at this white Qi Replenishing Pill, no matter the color or size, it was no different from the last time Yao Shan refined, but I didn't know if Lu Dao was also an extremely high-grade pill.

And Yao Shan just glanced at it and nodded and said: "Yes, it is extremely grade, in fact, the grade of the pill is also very easy to distinguish, it is also with spiritual sense, there is both aura and medicinal properties in the pill, the more the quantity, the higher the grade will naturally be, okay, young master, congratulations, the first alchemy was actually refined into a first-grade pill, if you don't feel tired, just refine all these remaining medicinal materials." ”

Looking at this first-grade first-grade qi replenishing pill that he had refined with his own hands, Ye Dong's heart also felt a sense of satisfaction, but Yao Shan glanced at Ye Dong deeply with a hint of envy, then turned around and left the room.

There is no way, even if a calm person sees a sixteen-year-old boy who has not even condensed his dust body, after trying to refine medicine for the first time in his life, he actually refines the extremely first-class elixir, he has to be a little jealous!
