Three days later, deep in the old forest of the western mountain.

There is a waterfall in front of the cliff, which is three thousand feet away from the cliff.

Lu Fan stood under the waterfall, only a smooth stone under his feet.

**On the upper body, Lu Fan stood on the stone, close to the full strength not to let himself fall. The water below has become boiling hot. There is a small purple fire at the bottom of the water. It is such a purple flame that makes all the flowing water passing by extremely hot.

The current of the waterfall hit him mercilessly. Lu Fan tries to adjust his body and mobilize the air flow in his body.

Focus, hold your breath.

Slowly cover the air flow in his body near the soles of his feet to form a wind and lift his body.

This is the way of fighting for the alchemists. One wisp of vital energy can be turned into five elements of heaven and earth. As long as we make good use of it, we can do all kinds of strange things.

But now, Lu fan can't even do the most basic condensation wind. At the foot of the air suddenly scattered, Lu Fan a standing instability, fell into the water.

The scalding water made Lu Fan cry out. The skin turned red all at once.

Hurriedly, Lu Fan climbed up the stone again, if the water below is just ordinary boiled water. But the water that the purple heart flame burns, however, carries the blazing heat far beyond the ordinary boiled water.

It seems that it's not only his skin and muscles, but also his bones and viscera.

Lu Fan sticks to it with his teeth clenched. His cultivation has just begun.

Not far away, Wu Chen is strengthening his house. Trees in his hands quickly turn into tables, chairs and benches.

Wu Chen doesn't look at Lu Fan's side at all, as if Lu fan is not his business even if he is burned to death.

What's more, this practice is nothing but appetizer.

Lu fan has been fighting against the waterfall for a day. In the evening, there is not much time for rest. Because he still needs to take advantage of the night to refine a pair of Qingyuan powder for scald treatment.

The method of making Qingyuan powder was taught to Wu Chen on the first day of his arrival.

At that time, Lu Fan only thought that it was a common practice of medicine cultivation. Who could have thought that this was a special healing for himself.

One day's high-intensity cultivation will cause some damage to the body, especially at the beginning of the day, Lu fan is almost red.

Bear the pain and refine the medicine. If you don't do well, you will suffer even more tomorrow. Lu Fan hurried to practice medicine. This damned Qingyuan powder doesn't have a fixed formula. It just needs to understand and refine various medicines. There is no medicine, but there is more than one medicine. After all, all things are born with five elements.

What Lu fan has to do is to break up the five elements of the medicinal materials, find the part he wants, combine and refine it.

As long as the understanding is thorough enough and the herbs are refined well enough, the common herbs at hand can produce a good Qingyuan powder. But for the beginner, it's really a difficult task. Wu Chen asked him to buy such a complex medicinal material at will. It's not easy to recognize all of them, let alone which specific properties and how to extract them.

All by himself, Wu Chen occasionally comes to have a look, give some advice.

The first night, busy for most of the night, Lu fancai made a little bit of Qingyuan powder with poor color.

After eating it, he just eased his pain a little. The next morning, Lu fan would continue to fight with the waterfall.

Wu Chen does not know what he is refining. After several days, Wu Chen is very tired.

Five days later, Lu Fan was covered with bruises and almost no part of his skin was intact, which was the result of his practice of the fiery golden body. At least the fiery golden body can help him resist some heat. I'm afraid I'm seriously injured in bed now if I change to another warrior.

At night, after getting down from the stone, Lu Fan almost wobbled back to the room. I can't lift my hands quickly, but I still insist on making Qingyuan powder.

In these days, Lu fan has tested the effect of making Qingyuan powder after refining various kinds of herbs. Now he has finally found a way.

Grinding, purification, fusion and molding.

Although the movement was slow, Lu fan made a small bottle of Qingyuan powder in another hour. During this period, several times, Lu Fan almost fainted. But he did it.

A bottle of Qingyuan powder goes into his stomach. Lu fan can see that his body begins to recover quickly and the pain is relieved. A sense of coolness pervaded the whole body.

Take a long breath. Tonight's qingyuansan seems to be the best one. The effect is obvious. Continue to do this next time.

Feeling that the body is almost recovered, Lu Fan takes a pill out of the ring.

Xu Huodan, he has endured for many days without thinking about it.

This period of high-intensity cultivation has consumed the remaining medicinal power in his body. The body deficit is serious. It's just the best time to eat the false fire pill.

Lu Fan takes a deep breath and eats the empty fire pill.

At the next moment, Lu fan saw that his whole body was smoking like a fire.

The strong medicine, like a torrent, scours his meridians and bones. Lu Fan adjusts his breathing rhythm and guides the medicine into his limbs.

Gradually, Lu Fan fell silent in such a state, and the wound on his body scabbed and healed little by little. At last, he showed healthy and ruddy skin like peeling.

I don't know when, Wu Chen also stood at Lu Fan's door. Seeing Lu Fan's state, Wu Chen nodded with satisfaction. Slowly help Lu fan to close the door.

One night, I spent in Lu Fan's absorption of medicine.

The next day, the early morning sun shone on Lu Fan's face through the window.

Slowly open your eyes, Lu fan moves a little, then hear a sound of stabbing.

Looking carefully, I peeled like a snake. After getting rid of these disgusting things, Lu Fan moved his body and felt full of strength.

If you punch a little, there will be a heat wave. Lu Fan punched the doorplate.

The wooden door panel was punched through, and immediately, the whole board actually emitted burning smoke, and the broken sawdust was even blacker.

Lu Fanxiao looks at his fist, which undoubtedly makes the fiery golden body practice to a small success.

Run out quickly. Lu fan comes to the bottom of the waterfall again. His feet are windy. Lu Fan feels his Qi, which has increased a lot. As light as a swallow, standing on a stone, you will never slip.

This time, Lu Fan did not move like a mountain.

With a loud laugh, Lu Fan's whole body flashed red light, and the fire and gold came out, and the water flowed and boiled.

Laughter goes straight up to the sky, shaking up countless birds.

In the next few days, Lu Fan had a lot of fun. Although occasionally he will be washed down by the water, the hot water can't do anything to him. The pain is still there, but it's harmless.

Unfortunately, such days didn't last for several days. Seeing that this kind of cultivation had no challenge to Lu fan, Wu Chen immediately changed his cultivation method again.

At the top of the waterfall, Wu Chen puts a ray of purple fire into it. This time, all the water left on the cliff has become boiling water. Not only that, Wu Chen also took out what he had prepared these days. An irregular stone was hung around Lu Fan's neck.

Suddenly Lu Fan felt that his body was as heavy as a kilogram, and it was very difficult to lift his arm.

Wu Chen explained with a smile: "this is fenglishi, a special thing passed down from Shanggu. Ordinary Qi practitioners can't make it. The process is very complicated. The only effect is to suppress the wearer. In ancient times, the alchemists used to imprison criminals by means of fenglishi. Of course, that kind of sealing stone is more terrifying. It can make a successful warrior unable to move and die in pain. What I bring to you is only a small version. "

Lu Fan listens to the corner of his eyes and jumps. Such a strong pressing force can only be regarded as a tiny version. Lu Fan stood in the same place and only moved a small step for a long time.

Wu Chen looked at him and said, "your next task is to climb to the top of the waterfall with this thing. No matter what method you use, climb to the top, this stage of cultivation is over. "

Lu Fan opened his mouth wide. As expected, this kind of cultivation will kill people.

Wu Chen patted Lu Fan on the shoulder and said, "of course, I will leave you a Book of medicine making. There is a way to remove the seal stone. If you can find it and succeed, you have passed this stage. I said, any way, as long as you can climb to the top of the waterfall. "

Lu Fan looks at Wu Chen and can't even nod.

Wu Chen doesn't say much anymore. He leaves with his hand in his hand. Lu Fan stood in the same place for a whole day.

Five days later, Lu Fan was barely able to walk, but the speed of walking was slow and he couldn't look straight at him. He was not as good as the child who just learned to walk.

Ten days later, Lu Fan was finally able to eat on his own. He was reading the thick medicine book in red light.

Fifteen days later, Lu Fan fell into the water under the waterfall and almost drowned.

Twenty days later, Lu Fan began to climb up against the terrible hot water waterfall, but after only three Zhangs, Lu Fan fell down again.

Twenty five days later, Lu Fan was finally able to skillfully transform the Qi in his body into the force of wind, which not only attached to the soles of his feet, but also covered his whole body. Only in this way can his body not look so heavy. At the same time, the muscles of his whole body became extremely firm. With his fingers alone, Lu Fan could grasp the rock out of the deep hole.

A month later, Lu Fan sat at the bottom of the waterfall, with a slight red light on his whole body. When the water fell one inch above his head, it separated itself. This was the manifestation of the air diffusion in his body.

Breathing is steady. Every time Lu Fan exhales, he will bring a heat wave.

Slowly, Lu Fan's body began to show subtle changes, blue tendons beat, like exultation, muscle contraction, rapid strengthening.

Suddenly, Lu Fan opened his eyes, eyes full of pure light.

Turn hands, Lu Fan a boxing to the bottom of the water, the whole body airflow into flame, a piece of water was evaporated clean in an instant.

Wu Chen stood on the bank and looked at it. He said with a light smile, "Lu fan, you have entered the eightfold training."

Lu Fan shook his fist and said, "this time let me see how high I can climb."

At the end of the speech, Lu Fan leaped up against the waterfall, climbing steadily and firmly.

Just like his martial arts!
