"Oh, show me!"

Lin Fei smiled, although there is only one internal martial arts method, there are seven different martial arts cheats, which is also good.

In Lin Fei's opinion, it is impossible for these big leaders to have too advanced internal skills, and if there are many martial arts cheats, it will be greater for his strength to improve.

Now for him, martial arts are more important, of course, if there are more advanced and can break through the secret books of the Great Perfection of the Day After Tomorrow, then it is another matter.

"Rainbow Heart?"

Lin Fei took the cheats and quickly looked at it, the acquired martial artist is to improve himself and improve his physical fitness, this is the so-called acquired refining body, but the physique is good, people's energy is naturally vigorous, and this memory is also greatly increased, after reading it casually, Lin Fei has already had a preliminary impression of this rainbow heart method, and it is also the basic internal strength cheats, which can be slightly stronger than the primary internal strength heart method, which is better than nothing, and it should still have some effect.

At that moment, he first put this rainbow heart method aside, and then looked at it again, seven martial arts cheats, five are sword techniques, two are boxing techniques, and they are all basic kinds, but the power is different.

If you are a different person, you will naturally choose an exercise after careful comparison, but Lin Fei is different, he has the plug-in of the colored progress bar, and a day's cultivation is several years for others, for him, the least fearful thing is that there are too many exercises.

"The Rainbow Heart Method and other martial arts can be practiced, but they are still one by one, so after reaching the extreme, I will go to practice something else!"

Soon Lin Fei made up his mind to pay attention, and in the future, he practiced the Rainbow Heart Method and a martial art every day, and he had no choice, so he directly took out a copy and began to cultivate.

"Iron sand palm, it's a good punch technique, but it costs a lot to get it quickly!"

Lin Fei smiled slightly, consumption is nothing to him, now that there is enough silver in his hand, cultivating this fist technique will not be difficult for him at all.

At that moment, he asked his henchmen to buy a large number of materials needed to cultivate the iron sand palm, the iron sand is a must, and the corresponding potion is necessary, otherwise it is easy to waste the person's palm.

For initial cultivation, Lin Fei prepared tens of thousands of taels of silver, and it was important to ensure the best cultivation conditions.

The first step in the cultivation of iron sand palm is to muster enough strength to keep your hands rubbing in the iron sand, and slowly adapt to the grinding of iron sand, and then put the iron sand into a large iron pot, slowly heat, initially not too hot, the temperature should be controlled in a certain range, and then slowly heated, until a pair of hands can be in a completely heated large iron pot, skillfully stir-fry the iron sand, this is considered to have reached the great completion.

It can be said that the cultivation conditions are quite harsh, but after training, a pair of iron palms are like iron and stone, which can resist swords, and hit people with one palm, which has the power of breaking gold and stones!

"Let's get started!"

Facing a big iron pot, Lin Fei took a deep breath, he is the day after tomorrow Great Perfection cultivation, his body is already strong, but he doesn't need to practice step by step, he can directly start to heat the cauldron to practice, but at the beginning, he can only slowly heat the iron pot on low heat to control the temperature of the iron sand.

"Drink!"

After puffing up, Lin Fei's hands were inserted into the cauldron of slow iron sand, and he began to stir up the iron sand according to the knack of iron sand palm cultivation, and his entire hands were sharpened by rough iron sand, in this process, Lin Fei felt that his hands began to ache gradually, but now his body's internal force is constantly surging, and his qi and blood are full, and this slight damage can be recovered in a moment.

This is also a benefit of cultivating iron sand palms for people with internal strength, as long as it is not too much damage, it can be recovered on the spot, and it also saves countless medicinal materials and a lot of repair time.

And Lin Fei's cultivation not only has internal strength, but also a powerful colored progress bar, an inexplicable force acts on Lin Fei's hands, every stir-fry practice, it is as if others have stir-fried 10,000 times, hundreds of thousands of times, every time he stir-fry, Lin Fei can feel that his hands have become more and more hard, but after ten stir-frying, now this iron sand, which is not much higher than the normal temperature, can no longer have any effect on his hands!

"Sure enough, the acceleration effect of the colored progress bar is still there, so you can try to heat up the heat and stir-fry, it seems that within a day, I have the possibility of practicing the iron sand palm into a masterpiece!"

Lin Fei's eyes flashed, this was the terrifying effect of the colored progress bar, and the acceleration effect on cultivation had simply reached an incredible level!

An ordinary person who has been cultivating for ten years, doesn't know how much pain he has to endure, how much tempering he has to go through, and how much he has to spend a lot of medicinal materials to become a great iron sand palm, Lin Fei can actually practice it in one day now!

This gap is really too big!

Of course, Dacheng's iron sand palm is still not Lin Fei's goal, his goal is to reach the point where he is superb, and there is no increase, this is his goal, Lin Fei's belief is a practice, and he must practice to the extreme, since he has a strong Ten Thousand Worlds shuttle door, he doesn't need to care about the world of this world at all, and there is also the acceleration of the colored progress bar, he doesn't take the extreme as the goal, isn't it a waste of his plug-in means?

After practicing over and over again, as the fire continued to heat, the temperature of the iron sand gradually rose again, Lin Fei also felt the slight pain in his hands again, the fire continued to heat up violently, and the temperature of the iron sand soon exceeded 100 degrees, but Lin Fei didn't feel too much pain at all, it was only a slight pain.

After a while, the iron pot turned red, and the iron sand gradually turned red, but Lin Fei's hands were only faintly red, a little painful, and as he practiced over and over again, this pain continued to weaken, although it was only a little, but this is the ironclad proof that Lin Fei is making rapid progress!

"Cool!"

Of course, Lin Fei was not blindly practicing hard, he would take out his hands at about the same time, and then put them into a potion containing a large number of precious medicinal materials, with the internal force and his body's self-healing ability, to quickly restore the damaged hand cells.

And when his hands are almost recovered, he will continue to practice!

With the passage of time, by the time it was night, Lin Fei's iron sand palm had almost been cultivated to the fullest, at least he mustered up enough strength, enough to bear the reddish iron sand with both hands in a short period of time!

"Bang!"

After soaking the potion with both hands, with a casual blow, the wooden stake used for martial arts training actually clicked and broke in half!

"The power is really good, this iron sand palm is now not inferior to the general people who specialize in iron sand palms, five or six years of skill, it seems that it is not difficult to cultivate to Dacheng in one day!"

Lin Fei laughed, and then strode towards the cultivation room, night is a good time to practice internal strength, and now that he has obtained the Rainbow Heart Method, he can also practice well!
