This time, Yang Fan was also divided into seven stages in the Dan furnace.

The first seven days were mainly to absorb the vitality of those medicines, and Yang Fan had to suffer from the erosion of ten thousand ants in these seven days.

After seven days, the second stage is reached.

At the beginning of this second stage, the fire gradually slowed down, and the small fire was combined with various calming medicinal materials to ensure that Yang Fan was always in a state of wakefulness, and this state was continued.

The third seven days were to add other drugs to start treating Yang Fan's body.

This is different from the first stage, this time the medicine is mainly to treat some rare drugs in Yang Fan's body, and its role is not only to provide vitality, but also to maintain the body and increase strength.

The first three stages are basically foreshadowing, and although the process may be accompanied by pain, these are nothing compared to the later ones.

The fourth stage is body refining.

This is mainly for Yang Fan, his martial arts are still very different from the martial arts of this world, Yang Fan's cultivation is a common method in the universe, the body is the foundation, and every cell in the body is where the qi is stored.

This world is the cultivation of the Dantian Qi Sea, although the master is also extraordinary, but there are often some flaws.

This is not to say that the wisdom of this world is low, it's just that the Heaven and Earth Yuan Qi here itself is not as rich as the universe, and the cultivation of the entire body is many times more than the Dantian Qi Sea, so this compromise method will appear.

The purpose of refining the body is to improve Yang Fan's physical fitness, and it was originally possible to absorb the external vitality to achieve a qualitative change in the body when he broke through, but because the vitality here was thin, he had to take precautions.

Of course, this has another effect, that is, it can help Yang Fan persevere in the outburst of qi in the back, so as not to be injured and difficult to recover.

The pain of refining the body is far better than the previous three stages, not only is the numbness in the body unbearable, but also all kinds of severe pain constantly appears, and there will even be magazines in his body to constantly eliminate it.

The fifth stage begins to really prepare for the breakthrough.

This time, all the herbs that were put in were herbs that increased power.

Yang Fan was already at the peak of the second order before, but this seemed to be only one step away from the third order, but it was the difference between heaven and earth, and those remaining skills would be lost in the future, so the strength must be increased.

Among the medicinal materials put in this time are many rare and rare medicines such as thousand-year-old vermilion fruit and 10,000-year-old snow ginseng, which contain unimaginable medicinal power.

Yang Fan is not stupid, these medicines are precious and abnormal, and it seems that only that King Qin has the energy to find so many heavenly and earthly treasures, and this time he owes a lot of favors.

Zhu Guo's medicinal power was blazing, and as its medicinal power entered his body, Yang Fan suddenly felt that his internal organs were burning, and his whole person seemed to be in the volcanic lava, and after a while, sweat was like rain.

The medicinal power of the 10,000-year-old snow ginseng was extremely cold, and Yang Fan shivered as soon as he touched it, and his whole body felt as if he was in liquid nitrogen, and in just a moment, a layer of frost condensed on his body.

Among these medicines, Zhu Guo and Snow Ginseng are the most powerful, so Yang Fan was most impressed by these two.

The temperature of the furnace outside continued to rise, and the medicinal power was steamed into Yang Fan's body.

At this time, Yang Fan's body was generally red, blazing like fire, and the other half was extremely cold, cold like ice.

In this process, Yang Fan was really immortal and painful, and the qi in his body was difficult to mobilize because of the injury, and he had to support it with his will, and even the qi in his body began to grow faintly under the effect of this heavenly treasure, making Yang Fan's body more and more uncomfortable.

The two heavens of ice and fire undoubtedly tortured Yang Fan very badly, but this was not unfounded, Xu Fu's alchemy was based on Taoist doctrine, and its fundamental idea was that yin and yang were born together, and dragons and tigers converged.

Zhu Guo and Xue Ginseng are one yin and one yang, which is in line with the principles of heaven and earth, although it has brought Yang Fan endless pain, but it has also brought him endless possibilities, in the constantly intertwined ice and fire, the qi in Yang Fan's body is increasing rapidly.

The most difficult thing to survive this time was the sixth stage, and within the sixth seven days, what was put into the alchemy furnace was no longer those great tonic medicines, but many poisonous medicines, and began to heat the alchemy furnace with maximum firepower.

At this time, Yang Fan was already exhausted, he had just passed the test of ice and fire, and at this time, suddenly the outside world began to increase the temperature.

"It's hot, it's hot! It hurts, it hurts! Yang Fan kept wailing in the Dan furnace at this time.

This time, the furnace temperature was much higher than before, and even the fire boy outside the furnace needed to change a group of people every once in a while, let alone Yang Fan who was in the furnace.

Moreover, this time there were also many poisonous medicinal materials in the furnace, and the medicinal power of these medicinal materials began to destroy after penetrating into Yang Fan's body, making Yang Fan miserable.

"Ahh The screams that came from inside the furnace made the fire boys outside the furnace tremble one by one, and they knew that the people inside must be suffering from ordinary people just by listening to the sound.

"I can't stand it anymore, let me out, let me out!" Yang Fan's voice in the furnace reached outside the furnace, and several boys who were really fanning the fire turned their heads and looked at Xu Fu in front of them, waiting for him to make an idea.

"Brother Yang, bear with me for the time being, you must know that the heavens will descend on the Si people, and you must ...... first"

"But it's too painful, not only the temperature, but also those poisons, why do you put so much poison!"

"This is also a matter of no choice, Brother Yang, only strong external pressure can really stimulate the potential in your body, I have prepared for this time in the past few weeks, the residual medicinal properties of those drugs in your body are enough to help you break through, but Brother Yang, you have to hold on to it!"

"Ah......" The scorching temperature and toxicity made Yang Fan extremely uncomfortable, and his whole person couldn't help but start dancing in the furnace.

Of course, without him noticing, those chaotic qi began to flow through his body, and this only intensified his pain even more.

"Ahhh......h

After the mobilization of qi in his body, Yang Fan was eroded by the heat and toxins, and his skin began to burn and even deteriorate, but this triggered the vitality in his body.

Destruction and regeneration go back and forth, this is really a survival can not be a death, and later, Yang Fan has no power to vent, so he can only sit down and concentrate on resisting these violations of the body.

"Palace Master, no...... There is no sound, Mr. Yang will not die! A little boy looked at the inside without the slightest movement, and couldn't help but ask Xu Fu with some worry.

"It's okay, just keep burning the fire!"

Xu Fu had already calculated the heat, and this heat was able to give full play to the effect, and if it was reduced, the effect would be greatly reduced.

I have to say that Xu Fu's calculation is exquisite, and although Yang Fan in the furnace is not in a good situation at this time, he has not yet reached the point of running out of oil and drying up.

Yang Fan was scorched black at this time, the skin on his body had been carbonized, and a lot of poisonous power began to swim in his body, and the whole person couldn't feel a trace of vitality at all from the outside.

But this is not Yang Fan's limit, in the imperceptible body, the originally scattered qi began to defend itself against foreign enemies in the face of these external oppressions.

The originally distinct qi began to fuse, not only the qi in Yang Fan's body, but even the medicinal power that was originally absorbed also began to play a role at this time, and the qi in Yang Fan's body was lost but increased more per point of fusion.

In the process of continuous fusion of this qi, Yang Fan's momentum gradually began to become stronger, and his body began to become stronger in the continuous destruction and rebirth.

Waiting until the last day of this seven-day period, Xu Fu frowned when he saw that there was nothing abnormal in the furnace, if nothing else, if Yang Fan's breakthrough went well, he should be able to cause some visions, but now it is still mediocre, even if he can recover from his injuries, it is difficult to go further.

As the saying goes, if Yang Fan's method of oppressing his own potential this time cannot break through, it will be more difficult to hope for a breakthrough in the future.

Thinking of this, Xu Fu also gritted his teeth, "Fight, the victory or defeat is in one fell swoop!" ”

"Put that cold star grass in the furnace!"

Xu Fu's words frightened those boys, "Palace Master, the cold star grass is very poisonous in the world, that is, the giants of the Mo family died under it, think twice!" ”

"It's useless to say more, as the so-called wealth and danger are sought, if this time is successful, not only will it become a master, but it can also create a body that is invulnerable to all poisons for him, I have made up my mind!"

Those boys had no choice but to follow Xu Fu's meaning, but when they took the Cold Star Grass, they were also wearing gloves, and they didn't dare to touch it in person, just because the Cold Star Grass was a special poison in this world, and it was extremely poisonous, even if it was skin contact, it would die in less than a moment, and everyone in the world was afraid of it!

Yang Fan didn't know that this kind of highly poisonous thing would be added to the alchemy furnace.

Now Yang Fan has fallen into the realm of fetal breathing, and the whole person is running the qi in his body with all his strength, but there have always been two powerful qi in his body that are difficult to fuse, it is the scorching qi produced by Zhu Guo and the cold qi produced by snow ginseng.

These two qi were difficult to fuse until another powerful external force struck.

The poison of the cold star grass is rare in the world, and according to legend, it is the resentment of the golden immortal master who fell in the battle of the immortals in ancient times, even if it is one of Zhu Guo and Snow Ginseng, it is difficult to compete with it.

Under such circumstances, the two finally gradually fused and produced a new qi, which was constantly repelled and fused in the process of entanglement with the poison of the cold star grass, and finally the three merged into one, regardless of each other.

The Tao Sutra has a saying, the Tao gives birth to one, one life to two, two to three, three to all things, Yang Fan before the intersection of yin and yang, and at this time it is three to all things, as the so-called things must be reversed, the new life that integrates the poison of the cold star grass is full of vitality and contains infinite possibilities.

At the moment of Yang Fan's success, the temperature of the furnace dropped sharply, and the entire square became cooler, Xu Fu smiled when he saw this, "It's done!" ”
