In the room, a scorching flame burned on the lower floor of the medicine pod, and there was dark red blood stretching and wriggling in the middle, and black impurities slowly protruding between the swallows.

There were two more white jade bottles on the table, which contained the freshly baked snow ginseng and the extracts of Tiannan Bai, don't look at the only two small bottles, but they contained the main essence of expensive medicinal materials, and with Chu Yu's alchemy technique, it took a lot of effort to successfully complete it.

After the first round of refining, Chu Yu was already sweating on his forehead, but he was in excellent condition, so he didn't rest, and continued to refine the main ingredient mountainback tiger blood.

The Mountainback Tiger is a rare breed among the second-order demon beasts, and there is a slight possibility of evolution. Its essence blood is said to have been transmitted from high-level demon beasts, and it has the strange effect of refining the body and strengthening the muscles and bones.

Of course, unless you are gifted, no one directly uses it to quench your body, because that is self-harm. However, if the nourishing snow ginseng and the healing Tiannan Bai are added to it to neutralize, it will be a treasure that countless body cultivators covet.

Due to the special essence and blood of the mountain-backed tiger, the impurities in it are very difficult to refine, about this, the person concerned, Chu Yu has a deep understanding, and the purification has not yet been carried out halfway, and his forehead is already covered with beads of sweat the size of beans.

Originally, the two ingredients added up to only two tea times, and the refining of tiger blood was carried out for nearly half an hour, and it was still extremely resistant, spitting out impurities tepidly.

Seeing this, Chu Tian sighed in his heart, Snow Beard Ginseng and Tiannan Bai alone would cost at least more than 200 gold coins to buy, how expensive should it be if the essence blood of the mountain-backed tiger was so difficult to refine? Is it four hundred, or five hundred? If the main material is not provided by his father, with his net worth, he will definitely not be able to afford this thing.

And Chu Chu cared more than himself, his eyes were like lakes, and there were two fiery red balls burning in the depths, which were the reflection of Ding Huo.

It took more than an hour for the essence blood to be refined, Chu Yu extinguished the flames, took out the essence blood, put it into the empty bottle, breathed a sigh of relief, and relaxed his demeanor.

Continuing to suppress the temperature of the flame for so long, if it is low, it will not be able to force out impurities, and if it is high, it will destroy the essence and blood, which will not only test the technique, but also test the endurance, even he is very tired at this time.

"Damn, this ointment is the most difficult to refine in the second grade pill, and it really contributed today. ”

After complaining in his heart, Chu Yu secretly groaned, the next step is fusion, this step is very critical, once successful, the subsequent knotting and baking will come naturally, if something goes wrong, the previous hard work will be wasted.

Catching a glimpse of his daughter's concerned and hopeful gaze, Chu Yu gritted his teeth, he had to practice this medicine for his daughter, and he couldn't be careless in the key step.

Thinking of this, Chu Yu rummaged in the medicine cabinet in the corner, and pulled out a flat vial from the drawer below, which contained the turquoise medicinal liquid.

Finding a chair to sit down, Chu Yu raised his head, hung the bottle on his temples, opened the cap, and dropped a drop of liquid medicine on each side, the liquid medicine was bright in color and smelled like pine resin.

Chu Tian, who was watching from the sidelines, felt that this medicine was extraordinary, and this conjecture was quickly confirmed, and after a while, Chu Yu finished resting, and his state even exceeded that when he had not refined the medicine, his eyes were full of light, and his eyes did not seem to contain the slightest impurity.

Chu Yu lit the fire again, with a flick of his sleeves, the three bottles of extracts were all opened, and different materials entered the top in turn.

These materials have very different medicinal properties, as soon as they enter the Ding, they are restless and noisy, mutually exclusive, and will never be fused together, the Ding Zhong crackles and the violent sound does not stop, and the whole Ding body is buzzing, this Ding is full of adult strong mangao, and it is quite scary to move.

Although Chu Chu often refined, it was the first time he had seen such a fierce resistance, and his pretty face turned pale for a while, and his eyes were full of worry. Chu Tian pulled her back two steps, and the two waited for the fusion to be completed.

Seeing this, Chu Yu was not in a hurry, grabbed the void, and forcibly suppressed it with his spiritual power. Although the Chinese medicinal materials in the Ding are mutually exclusive, the impurities have been purified just now, and most of the rage factors in the materials have been removed, and the rest are like trapped beasts that have fallen into a trap, which can only be regarded as the end of a strong crossbow.

He continued to exert his strength, and the medicine pod gradually stabilized, and the fierce crackling sound turned into a dull popping sound, from large to small, and finally disappeared completely. The dark red of the tiger blood in Dingzhong, the pure white of snow ginseng, and the turquoise of Tiannan white are entangled and fused, and the three colors rotate like a whirlpool, constantly converging and merging.

Eventually, the liquid took on a pure blue-red color and tumbled and rotated in the furnace.

Chu Yu lowered the temperature of the flame controllably, and the liquid medicine gradually turned into a paste. The quenching effect is best when this medicine is in the form of a paste, and it is a grade worse than either a liquid or a pill. The temperature must be controlled at a very delicate point to ensure that the ointment is made, not the liquid or the pill.

Refining medicinal ointment is far more difficult than ordinary medicines, and it is difficult for new practitioners to complete it independently, and only experienced veterans can succeed.

As the chief alchemist of the family, Chu Yu was among them. With all his strength, the liquid medicine turned into a paste, uniform and delicate, with no sign of solidification.

Seeing that the fire had arrived, Chu Yu waved his hand several times in the air, and the ointment was divided into five parts, and then evenly spread the ointment on the medicine stickers that had been prepared long ago, put it into a brocade box and handed it to Chu Tian. Chu Tian opened the box and checked, there was still a little warmth left on the medicine sticker, and he carefully closed the lid to avoid the loss of medicinal properties.

With the ointment in hand, Chu Tian couldn't wait to quench his body, and he didn't want to stay longer. Chu Tian took out his father's dark purple card and brushed the contribution to Chu Yu, which was worth twenty-two contribution points, equivalent to two hundred and twenty gold coins, which was more expensive than two fine snow ginseng plants, this was still the price in the clan, and if he went outside to ask someone to refine the medicine, the cost would be even more amazing.

During this period, Chu Chu also asked his father to waive the fee, which made Chu Yu cry and laugh, Chu Tian hurriedly opened his mouth and refused, after all, the family rules cannot be abolished at will, and the fee for refining medicine is even more justified, although he is young, he has his own bottom line in this kind of thing.

Chu Tian blindly insisted, even if Chu Chu was unwilling, he had to give up.

When leaving Chu Yu's father and daughter, the sunset was falling into the distant mountain col, Chu Tian got up and rushed home, and after arriving home, Chu Tian closed the door of the house, intending to quench his body immediately.

"Momentary strength" pays attention to the maximum strength in the short term, which requires the compression of muscles, and has extremely high requirements for the body, and ordinary martial artists cannot meet the standard at all. Tiger Blood Quenching Body Cream can effectively strengthen the body in a short period of time and quickly reach the bottom line of cultivating this skill.

Yu Jian's message said that the quenching pain is unbearable, very difficult, and only by persevering can the quenching be successful.

For Yu Jian's description, Chu Tian didn't dare to underestimate it at all, after all, it was a third-grade martial arts, and it was even comparable to a fourth-grade martial arts when practiced to a great extent, presumably this so-called pain and itch should not be a good match.

Recalling Chu Yun's meaningful smile when he proposed to practice this skill, Chu Tian trembled all over, and it seemed that most of the problem was in this quenching body.

After some hesitation, Chu Tian was ruthless, took out a medicine patch from the brocade box, uncovered it and pasted it on his chest as required, and the unbearable severe pain suddenly struck, making him almost faint.

In the human body, the most vigorous place of qi and blood is the dantian and chest, therefore, as soon as the quenching cream is attached to the chest, the skin seems to have been burned by a soldering iron, and the medicinal power quickly penetrates below, radiating out along the qi and blood in the meridians, evenly distributed to the limbs, the blood boils, and every fast muscle is active, excited and trembling to devour the medicinal power, becoming stronger and more powerful.

Although he had been fully prepared in advance, when he stepped into the formal link, Chu Tian was still unbearable, because it was too painful.

Regarding the pain, Chu Tian's deepest impression was when he went to the back mountain with Xiaoyue when he was a child, and he didn't fall into the trap dug by the hunter, the trap was one foot deep, he was only six years old at the time, you can imagine how much pain it was. When he was rescued, he was bleeding all over his body, with multiple bruises and a broken arm.

But the pain was still not as good as this time. The pain of quenching the body acts on the inside, and the specific taste cannot be known to outsiders, only the person concerned knows.

In penance, time is difficult to survive.

The quenching paste is divided into five patches, and generally speaking, each patch takes one day to absorb, that is to say, it takes five days to complete the quenching, which is a very long time for Chutian at this time.

This kind of pain is not known to outsiders, with the tenacity of Chu Tian's perseverance, he also instinctively wanted to remove the medicine patch and interrupt the quenching body several times, but in view of the continuous strengthening of the body, he forcibly dispelled this thought, and gritted his teeth and persevered.

At noon on the third day, through the window screen, the scorching sun was still hot, and Chu Tian's forehead oozed a little sweat. However, after a period of torture, perhaps because of gradually adapting to the medicinal properties, the pain of quenching his body was significantly reduced, and his frowning brows were stretched a lot.

Just when he thought that everything was stable and his mind was a little relaxed, an unimaginable itch suddenly came from the bone marrow, which spread rapidly from the inside out, and in an instant, his whole body itched, without the slightest warning in advance, which made Chu Tian very uncomfortable, and he couldn't hold back for a while, and moaned quietly.

Outside the house, Xiao Yue was standing pretty, her pretty face was full of worry, and with the temperament of the young master, she actually moaned, and the pain was far from what she could imagine.

"Why don't you persuade the young master not to practice this evil kung fu? I'm just a maid, whether this kind of persuasion is presumptuous, the young master won't be angry. ”

Xiao Yue couldn't help but think wildly, and tears welled up on her delicate face.

While she was thinking a lot, Chu Tian continued to endure the inhuman itch, his whole body seemed to be scratched by the naughty child's hairy hands and feet, and there seemed to be a centipede in his bone marrow.

Although he was out of control for a while, Chu Tian quickly stabilized his mind, thinking of the shameful laughter he suffered when he was a child, the beating Chu He had had, the oath he secretly made before the enlightenment, and the biography of the strong man he read when he was a child.

It records the life deeds of the world's powerful people, who either flew to the sky, or opened mountains and seas, or roamed freely, and their legends have been passed down from mouth to mouth on this continent and will never be exhausted. He Chutian also wants to be such a person, and he is willing to give everything for this.

As soon as he thought of this, Chu Tian's eyes were filled with silver light, and his willpower suddenly became several times stronger, and the originally unbearable itch did not seem to be unbearable.

Finally, on the fifth day, the mild morning sun sprinkled all over the land, and of course he didn't miss the silver-haired boy who was confined to the door and practiced hard.

At this time, the sky was just bright, and the darkness in the room had not yet receded, but the anxious morning light rushed in, and under the contrast of light and darkness, the young man looked gorgeous and quiet, like a painting hanging in front of the bed.

Suddenly, the painting moved, and the silence was ruthlessly broken. A little doubt flashed in Chu Tian's eyes, it had been a tea time since he put on the fifth medicine patch, why didn't his body feel at all?

After waiting for a long time, it still had no effect.

Chu Tian withdrew from the cultivation state, and after a little induction, all parts of his body were strengthened, his qi and blood were vigorous and comparable to the demon beasts of the back mountain, his muscles were as strong as those of a strong man with physical cultivation, and his muscles and bones were also strengthened.

The first three stages of the body training are mainly to exercise muscles and strengthen physical fitness, and it is only in the fourth stage of the body training that he turns to temper the bones, but because of the relationship between the quenching body, he carried out it in advance, which undoubtedly paved the way for the later practice.

The fact that Chu He was easily defeated before was not because the fourth-stage martial artist was weak, but because the gap between the two in martial arts was too big. Chu He has been practicing hard for several years, and the "Thunderbolt Legs" are only at the entry level, so he will naturally be abused by Xiao Cheng's "Whirlwind Palm".

After repeated investigations, Chu Tian felt that his physical body seemed to have reached the threshold of cultivating "Temporary Strength", but the jade slip said that the ointment was used up before it was successfully quenched, what was going on.

After thinking about it, he didn't understand, Chu Tian simply opened the medicine patch and put it back in the brocade box, changed clothes and washed and walked outside the house. I have to ask Chu Yun about this matter.
