The two most important things in alchemy Ye Feng have no problem, and with these two points, he has no problem refining the general immortal spirit pill. But to refine the Imperial Spirit Pill, these two things alone are not enough, there must be the deployment of materials.

Looking at the mountain-like precious materials that were wasted by himself behind him, Ye Feng shook his head bitterly, his allocation was not very accurate, which material was a little more, which material was a little less, although it was only a little subtle, but it would cause failure, he had been working hard for so long, seeing that his progress was not fast, Ye Feng couldn't help but be a little anxious.

"Mixing materials is the simplest and least important part, but if this link is not perfect, it will not be able to practice the Emperor Spirit Pill at all. Something had to be done. Ye Feng thought with his brows furrowed.

Some of the materials used in alchemy need to be mixed before refining, and some need to be added during the refining process. No matter which one you want, it's too difficult, and it takes a lot of experience to be able to get it all at once.

If you don't really get in touch with refining alchemy, you can't really understand the profundity of this science. Ye Feng now felt that this refining weapon alchemy was even more difficult than his creation of the four elemental attribute exercises.

Of course, in addition to relying on experience, there is also a way to mix materials, and that is to rely on spiritual sense, using one's own feelings. It's like there's a raging fire in front of you, you might think it's hot, but you can only guess how hot it is, but if you go up and experiment with it and put your hand in it and sense it, you'll know exactly how hot the fire is. The accuracy of psychic sensation is far a hundred times higher than that of experience. However, spiritual consciousness involves the soul, and if the soul is slightly injured, that kind of pain will be unbearable for ordinary people, so the alchemy refining masters of the entire continent have hardly taken this path.

But the current situation is that if Ye Feng doesn't take this path, then his alchemy refining weapon water quality can only reach the highest level of Yan Lu and Gu Wuyan, and he can't refine the Emperor Spirit Pill. But to take this path will undoubtedly be extremely painful.

Suddenly, Ye Feng's eyes seemed to remember that in the Life Heavenly Artifact Realm, he saw the scene of the disciples of the Holy Heaven Sect being killed one by one. And Ye Feng knew that the scene was all an illusion, but it was hard to guarantee that it was not like this in reality. The Holy Heavenly Sect needs to be strong, and it needs the shortest time to become strong!

"Damn, fight!" Ye Feng gritted his teeth and finally made up his mind.

Directly integrate his spiritual sense into the materials required for alchemy, treat all the materials needed for refining pills as a part of his body, and use his soul to sense the combination of various materials.

"Ahh

At the beginning, Ye Feng woke up in pain, which of those pills is not a heavenly treasure, the spiritual energy contained in these heavenly treasures is extremely huge, maybe these energy and spiritual energy are very good for cultivation, but the soul is not good, the soul is too fragile, no matter what energy or fluctuations, as long as it touches the soul, the soul will inevitably be unbearable, and the pain will enter the bone marrow!

"No, I can't hold it!" In just a moment, Ye Feng was sweating in pain, his eyes were watery, and his face was extremely pale. Moreover, this feeling made Ye Feng pass out as long as he held on for a second.

"Damn, it hurts me to death!" Ye Feng suddenly sat on the ground, breathing heavily. The Holy Spirit Necklace emitted a soft glow, which made Ye Feng's soul feel a lot more comfortable, but once he tried again, the effect of the Holy Spirit Necklace was very small.

"Can't give up!" After feeling much better, Ye Feng gritted his teeth and suddenly thought, "Since I can't hold on to such pain, then I will first exercise my muscles and bones, exercise my soul, and exercise until I can bear this pain!"

After making up his mind, Ye Feng directly began to temper his muscles and bones, suddenly, Ye Feng, who was sitting cross-legged, had an orange-yellow flame all over his body, and this kind of flame was enough to refine a medium-grade holy weapon, and the ordinary heavenly spirit would be stained with death, but Ye Feng frowned tightly, and endured the burning of this flame, the flame burned on the surface of Ye Feng, which was actually the extra fire that came out of the flame in Ye Feng's body. I don't know how long it took, Ye Feng seemed to be completely adapted, and then cold water vapor appeared on his body, cold water at the same level as the orange-yellow flame, and the two extreme forces of cold and hot met instantly, and there was a sizzling sound, and suddenly the sky was filled with white gas.

Temper your bones!

It was not the first time for Ye Feng to refine his muscles and bones, after all, Ye Feng's muscles and bones had reached the realm of high-grade holy weapons, thanks to the previous Ice Spirit Bead and Fire Spirit Bead. Now that the Water Holy Spirit Bead has appeared again, with the help of the Water Holy Spirit Bead, Ye Feng's muscles and bones will inevitably be stronger to a higher level.

Melting, quenching, every cycle, Ye Feng's muscles and bones become stronger, so I don't know how many years have passed! At the same time, when Ye Feng is also refining his muscles and bones, he begins to adjust step by step to exercise the soul, and the soul is sensitive, then it will only increase a little bit of weight in a hundred years, and such a slow cultivation to the extreme, as long as he perseveres, he can also accumulate water into lakes and mountains of soil, and achieve a strong soul.

I don't know how long it took, Ye Feng felt that the help of the Water Spirit Bead for refining the muscles and bones had been completely exhausted, just like the Ice Spirit Bead and the Fire Spirit Bead before, so he gave up cultivation and slowly opened his eyes, and at the same time, Ye Feng felt that his soul was not comparable to before.

And this more powerful bone and soul gave Ye Feng a sense of omnipotent self-confidence.

"Halberd, how long have I been refining my bones and soul?" Ye Feng asked abruptly.

"One million two million years, it's okay, it's just enough time for me to get some sleep!" said the Heaven-Shattering Halberd coldly.

Ye Feng smiled bitterly, more than a million years, what a long time for human beings, but it was only enough for the Heavenly Artifact to sleep, and the time for the Heavenly Artifact to exist was too long. This world says that it is only seven million years, but in fact, it is only seven million years from the time there was life to the present, but for an unknown number of billions of years before there was life, the celestial artifact already existed.

"Relying on the Water Holy Spirit Bead, my strength of my muscles and bones has broken through to the level of a lower-grade Immortal Hallow, but without the help of the Holy Spirit Bead, I have been refining my muscles and bones for millions of years, but I have only improved from the muscles and bones of the first-grade Immortal Sacred Weapon to the peak of the Lower-grade Immortal Hallows. And the last time I cultivated my muscles and bones in your reincarnation of death, it was also more than 300,000 years, and there was almost no progress. It can be seen that the speed of refining muscles and bones is really unacceptable. Ye Feng sighed.

"!The average three-line, three-turn Heavenly Spirit Emperor, the defense of muscles and bones is not as high as that of a holy weapon, and your muscles and bones have already reached the realm of an immortal holy weapon. Be content. The muscles and bones are so strong that they are invincible, and they don't have to die if they stand still. If you cultivate so well, everyone in the whole continent will cultivate, which round will get you. Let me tell you, without the help of the Holy Spirit Bead, even if you have been cultivating for 10 million years, you will not want to upgrade from a low-grade Immortal Sacred Weapon to a medium-grade Immortal Sacred Weapon. ”
