Nangong Yu did not leave the secret room all night.

During this night, the Neapolitan nobles bid farewell to the Venetian royal family and led their men out of Venice on their way home. Other countries also withdrew from Venice at about the same time.

The three Marquis of Moore, the head of the Moore family, asked to see Nangong Yu several times, but they were all blocked by Anna. And the news from Rosa's subordinates and everywhere, including the movements of other countries, etc., Anna also suppressed almost all of them.

Everything, just waiting for Nangong Yu to come out of the secret room!

Anna and Rosa were not worried about Nangong Yu, so they didn't sleep all night; The cooked meal is hot and hot, then poured out, then cooked again, then heated again, and poured out again...... And so on and so on more than a dozen times...... Rosa's skills are pure, although she hasn't slept all night, she hasn't been tired yet, Nangong Yu has also had similar actions before, and she has practiced in retreat and medicine many times, although she cares, she is still at ease!

It was the first time for Anna to wait for Nangong Yu, and she was worried about herself, especially from Rosa's mouth, she knew that the main purpose of Nangong Yu's retreat medicine was to refine the key drugs for treating her body meridians, which made the girl very moved, so she almost cried out loud, and her heart became even more uneasy. The meridians of his own body, as the Toby family of the first family, are helpless and have no way, what good way can he do as Nangong Yu? You must know that refining medicine is an extremely painful and exhausting job; if Nangong consumes his body because of refining medicine for me, whether the medicine is useful or not, it is my sin?

Alas, my Mr. Nangong, don't you know that I would rather never cure my illness than have any damage on you?

In the feelings of the two women, they both felt like years, especially Anna. At first, the two of them could still talk to each other to pass the time, but later, both of them closed their mouths tightly, their eyes fixed on the door of the secret room, and their faces were full of anxiety and worry.

Nangong Yu in the secret room has really reached a critical moment. In order to refine this "best Great Returning Pill", Nangong Yu thought that he was quite well prepared, and all the medicinal materials were in excess of the reserves, adding two catties; even before that, Nangong Yu secretly tested two times with ordinary drugs according to the refining method of the Great Returning Pill, and each time it was quite successful, so Nangong Yu was full of confidence in this alchemy.

Nangong Yu never imagined that refining the best elixir and experimenting would be two completely different things. In particular, the thousand-year-old blood participation in the ice crystal fire lotus, although it is a complement of civil and military, it is also a different furnace of ice and charcoal, which is difficult to reconcile.

After extracting the essence of the other twenty aftertaste auxiliary medicinal materials in turn, it was similar to the previous two experiments, and there was no mistake, but it was a pity that Nangong Yu confidently put the ice crystal fire lotus and the thousand-year-old blood ginseng into the Dan furnace together, and the open flame was extremely heartfelt. This has been the case several times in a row. This made Nangong Yu a big headache, if the two main herbs blindly contradicted and could not be fused, how to refine the pill? Moreover, these two herbs could not be divided and treated like other medicinal materials, otherwise as long as the aura leaked slightly, the medicinal power of the pill would be greatly lost.

In desperation, Nangong Yu had no choice but to take the most stupid method, continuing to control the fire with his right hand, and holding a jade short sword in his left hand, against the Dan furnace, passing on the power through the objects, and locking the two elixirs with his most exquisite internal force to prevent them from separating. But in this way, Nangong Yu suffered a lot!

Refining medicines, the most taboo is the intervention of foreign objects belonging to the genus of hardware, probably only jade items other than hardware can be an exception, but jade items are the most fragile, and it is extremely difficult to channel internal forces, and the Dan furnace is more steel, almost half a foot thick, Nangong Yu only seeks its strength when casting, and it is naturally extremely bulky. Now the internal force must first control the Dan furnace through the jade short sword, and then control the medicine remotely through the wall of the Dan furnace; invisibly, it will consume several times more internal force! It is not that Nangong Yu does not want to directly stick his hand to the Dan furnace to exercise power, but if that happens, once the temperature rises, it will inevitably roast Nangong Yu's palm to pieces, and Nangong Yu's skill is high, but it cannot compete with the natural high temperature.

However, this kind of luck is the most exhausting power, with Nangong Yu's extremely pure ninefold power of the first yin and yang formula, it only lasted less than an hour before he felt powerless, and now the two flavors of the main medicine in the Dan furnace have just begun to melt!

However, the fire can not continue to increase, it must not be angry, unhurried, both civil and military, and maintain a constant temperature, which is the best way to alchemy. Once you are in a hurry, I am afraid that the elixir in the Dan furnace will inevitably turn into a furnace of waste slag!

It's hard to ride a tiger now!

No matter what, it must be successfully refined! Nangong Yu's eyes were clear and calm, and he kept his true power flowing out continuously, and simply closed his eyes and concentrated on his exercises. The right hand mechanically controls the fire, and everything is calm and quiet, but under the calm appearance, there is a danger like boiling magma!

Two hours passed...... Three Hours...... Nangong Yu had a thin bead of sweat on his forehead, and his face turned slightly pale.

Six hours passed, Nangong Yu's face was covered with sweat like rain, his hair was tightly attached to his face, his clothes were as if he had just been fished out of the water, his face showed an abnormal paleness, only his cheeks revealed a little unhealthy redness, the blue tendons on his forehead were beating suddenly, his upper and lower teeth were clenched tightly, and his cheeks clearly bulged out with a fleshy edge...

Nangong Yu himself never imagined that in the two hours of the experiment, when it came to the real refining of the Great Returning Pill, it would turn into six hours before the complete work was completed! The Dan Furnace was like a bottomless abyss, absorbing all of Nangong Yu's incomparably thick Ancestral True Qi and draining it to be exhausted.

Nangong Yu's internal strength has now reached the point where the mountains and rivers are exhausted! The two eyes are also blurry, and a strong desire to not admit defeat rises from the bottom of his heart. Nangong Yu's eyes widened angrily, he roared wildly, and the last trace of true qi flowed into Danding along the jade short sword, and as soon as his eyes were dark, he lost his consciousness. Before losing consciousness, faintly, there seemed to be a strange fragrance in his nose, and Nangong Yu fainted as soon as he was relieved.

I don't know how long it took, Nangong Yu woke up slowly. Looking at the Dan furnace in front of him, Nangong Yu unexpectedly had an indescribable subtle feeling from the bottom of his heart, and when he was suffering from gains and losses, he didn't have the courage to open the Dan furnace to see what was going on.

Taking a deep breath, Nangong Yu settled down and sat up slowly, only to find that his whole body was soft and lacklush, without half of his strength; At that moment, he no longer hesitated, stretched out his right hand, and removed the top cover of the Dan furnace. As the lid of the furnace was slowly opened, a strong smell suddenly came to the nostrils, instantly filling the entire secret room. Nangong Yu suddenly felt extremely comfortable with his whole body, and his limbs seemed to be infused with strength, and he relaxed.

At the bottom of the Dan furnace, there were more than 100 blood-red crystal clear pills the size of broad beans, all round and transparent, like crystal agate. Bursts of strange fragrance emanated from these pills, and just smelling their aroma made me feel very relaxed.

Nangong Yu closed his eyes, and after a period of relief in his heart, a feeling of complete ecstasy rose. At this moment, Nangong Yu almost wanted to sing loudly!

This is a large number of Great Returning Pills, which means that Nangong Yu's invincible force is about to come out! With Massimo and other Rao skills, if he takes this Great Returning Pill and then increases his strength by ten years, his personal strength will be enough to go down vertically and horizontally! Except for a few people, there is no invincible opponent!

At such a critical moment when the war is about to break out, the strength has suddenly increased and Ruci has taken a big step, and now, Nangong Yu already feels that he no longer has any scruples!

Hurriedly took a few jade bottles that had been prepared on the side a long time ago, put a large pill of Huan Dan into it, tightly plugged the mouth of the bottle, and confirmed that all the Da Huan Dan had been collected, this time he breathed a long sigh of relief, and in an instant, an indescribable feeling of fatigue rose up, and he was almost drowsy. Nangong Yu pinched his thigh fiercely, and under the severe pain, suddenly the Lingtai was clear, now is definitely not the time to sleep, but it is the best time to recover his strength.

took out a big pill and put it in his hand, Nangong Yu sat cross-legged, and submerged the Yin and Yang Jue internal force exercises. At the beginning, I only felt that the dantian was empty, and gradually there was a trace of fine internal force swimming in the body, the speed became faster and faster, and the residual internal force in the meridians of the whole body was swept away, and a torrent of internal force was gradually formed, which stirred up in the dantian. Nangong Yu clearly felt that after his internal force had been consumed by the essence of today, it seemed that he had made another stage of progress in recovering again!

Taking advantage of the internal force to run to the extreme, Nangong Yu took the big pill in the palm of his hand into his mouth, and suddenly felt a cold silk thread flowing down his throat, and then a powerful and gentle warm current exploded in the dantian! A powerful and gentle medicinal power rose from the dantian, and instantly traveled all over the body, and suddenly the whole body was as hot as a fire.

Nangong Yu worked hard to control his own internal force, guiding this powerful external force, and running step by step in the meridians of the whole body according to the running line of yin and yang!

The true qi of the whole body seemed to be ignited at the same time! The golden crown of hair on Nangong Yu's head suddenly exploded, and his long black hair rushed straight up, and a strong air flow rushed out from the inside of his body, and the fine white brocade robe on Nangong Yu's body was torn into pieces by the violent energy with a pop, and he was suddenly naked!

Nangong Yu guided the powerful force that sprouted from this Great Huandan, and tried to merge with his own skills, but after a long time, it was unsuccessful, and the two internal forces separated as soon as they came into contact, and it turned out to be the appearance of the well water not violating the river water.

Thinking of this, Nangong Yu's eyes suddenly widened angrily, and he turned his heart horizontally, directly using all his own skills, mixed with external huge forces, and frantically impacted towards the key meridians of the Yin and Yang Jue!
