If Ye Feng can refine the Emperor Spirit Pill, I am afraid that Ye Feng's refining alchemy level is definitely the top in this world, after all, alchemy and refining are together, on the one hand, it is strong, then on the other hand, it is impossible to be weak.

"Let's learn the formation thoroughly first, refining the Imperial Spirit Pill is not something that can be learned in a moment and a half, and there is no hurry!" After a short period of thought, Ye Feng finally made up his mind, took out the formation knowledge that Gu Wuyan had given him, and Ge Tianlie's formation scroll and began to study it.

Soon, Ye Feng was smiling, looking very enjoyable, obviously completely entering the state of learning the formation.

Learning should be carried out in part of the class, little by little, and it is necessary to know that the speed is not reached. And at this moment, what Ye Feng was studying was the simplest first-level formation.

The formation is also divided into levels, the higher the level, the more powerful it is, and of course, the more difficult it is to deploy such a formation. In fact, whether it is a high-level formation or a low-level formation, it is to use the difference in the position of each energy body to coordinate and match it to make it play the greatest effect. And these energy bodies are called formation bases, and all formation bases are arranged according to different directions, which are called formations.

If the energy bodies under the base of each array are the same, even if the energy inside is large, the power is not as good as before, and it will also cause a waste of energy. As for where each energy body should be placed in order to exert its greatest power, it requires the purpose of the formation and the experience and ability of the person who arranged the formation, that is, the formation cultivation.

Sometimes, according to the formation book, the power of placing a piece of energy body here is one, if you accidentally shift the position of the energy body a little, the power of the entire formation may be increased to ten, but more often the entire formation will be destroyed, so the formation is endless.

At this moment, Ye Feng was like a child, holding the scroll in his hand for a while, thinking with frowns, and then temporarily injecting his strength into the stones, and then laying out the formation he had just learned, looking at these stones with only a little energy, and exerting great power according to his own will, Ye Feng suddenly rejoiced.

"Hahahaha, interesting, interesting!"

At this time, Ye Feng was completely addicted to it, and his face was full of smiles. Just now, a complex formation that had been deduced for three whole years, Ye Feng finally succeeded in deducing it.

This feeling of continuous research and continuous efforts, and finally achieving success, gave Ye Feng a sense of conquest.

Later, Ye Feng had to study the principles of each formation and what could be improved, and even study the formations that were similar to him, mutually beneficial, opposite, and mutually restrained, etc., when Ye Feng closed his eyes, thousands of formations could instantly appear in his heart, and at the same time, there was a feeling that he could easily deduce countless more complex formations, and he could also create new formations at will, learn from the past, and even lay out more advanced formations.

"The so-called weapon is extremely powerful, it is the original weapon that has the increase of the formation, but it is too difficult to put the formation into the weapon, and then refine it, I am afraid that at least the treasures above the immortal holy weapon can have the formation. And the so-called pseudo-celestial artifacts and celestial artifacts can be attacked by the power of the law, and it is even more because the formation inside is strong enough to exert the power of the law. And the three formation spells that Tai Shuai took out to deal with Yan Lu are actually a kind of weapons, but the power of the formation in his place can explode in an instant, producing huge destructive power. I see, I see!"

As Ye Feng continued to study deeply, many things that he didn't understand also understood.

"It's just that the formation is extremely time-consuming, and it is almost useless in actual combat, but it is very important for refining weapons and alchemy!" Ye Feng had a smile on the corner of his mouth, after all, this was enough for him.

It took 100,000 years to study the Four Elemental Attribute Exercises, but it took millions of years to study the Formation! Now Ye Feng's Formation Strength is probably far surpassing Gu Wuyan's.

"I've been studying for so long, it's time to give it a try. Ye Feng smiled, but Ye Feng was still very cautious, he was not so arrogant that he could refine the Emperor Spirit Pill for the first time in alchemy, but started with a low-grade pill. After all, the space ring left by Ge Tianlie in the eighth formation contained his life's treasures and refining materials, and these things Ye Feng and Yan Lu were half and a half, so now Ye Feng did not lack the heavenly and earthly treasures for refining pills.

I saw that Ye Feng was now using the materials left by Ge Tianlie, constantly blending, and matching various materials according to the best ratio recorded in the scroll. The matching of this proportion must be exactly the same, and I don't know the slightest difference, and the error is thousands of miles. And in order to achieve the perfect blend of various materials, it takes experience, to put it bluntly, it is a very high degree of feeling.

"Damn!" Shaking his head in disappointment, Ye Feng directly threw away the lower-level immortal elixir that he had just refined. The treasures are divided into holy weapons, immortal holy weapons, and venerable weapons, and this elixir is also divided into holy pills, fairy spirit pills, and imperial spirit pills. The immortal spirit pill that Ye Feng had refined was already considered successful by the standards of ordinary people, or even better, but Ye Feng knew that with the level of refining this immortal spirit pill, he couldn't practice the emperor spirit pill at all. The requirements for refining the Immortal Spirit Pill are low, and a small mistake and a small deviation will not fail, but the Emperor Spirit Pill will inevitably fail if it is slightly deviated!

Refining extremely high-grade pills also requires the protection and assistance of advanced formations, which is the most important. And the second most important thing is the heat, the natural materials and earth treasures for refining the pill are extremely fragile, and the medicinal properties in it are more likely to be lost, this heat cannot be too small, too small the medicinal effect will not achieve the effect. It can't be too big, it's too big to turn into ashes directly, it's not the end. Moreover, the requirements of each time period of the fire are also different, and the temperature changes in them must also be grasped extremely accurately.

And Ye Feng's current formation fully met the requirements, and there was no problem with the fire of his refining pills, because Ye Feng had the physical sense to control the flames. After all, what level of flame Ye Feng's muscles and bones can emanate from his body. Now that the strength of his muscles and bones has reached the peak of the inferior holy weapon, he can naturally emit such a strong flame, refining the pill is not refining the weapon, the temperature should not be too high, but it must definitely be accurate. Ye Feng sensed the temperature with his body, and controlled the change of temperature with his body, which was naturally a hundred times more accurate than ordinary alchemists who reduced or increased the amount of fire according to experience.
