Once the Spiritual Qi Spring is swallowed by him, the Spiritual Qi Spring is likely to be devastated, and at that time, this valley will become a useless place, and it will be meaningless for the Ke family to come here, as if they just stay in Kejia Village.

Every time the Heaven Devouring Battle Method is promoted to a small realm, the aura required is at least three times the total spiritual power required by all the previous realms, which is the approximate need that Chu Chen summed up, but in this way, it is also an extremely terrifying number.

Almost half an hour later, Chu Chen stopped, and his face couldn't help but show a hint of self-deprecation, because he found that his original estimate was wrong, the aura needed in the middle stage of foundation building had exceeded his estimate, and if he wanted to push his cultivation to the peak of the middle stage of foundation building, the aura in this valley was not enough, even if he devoured the spiritual vein, it was estimated that he could only rush his cultivation to the peak of the middle stage of foundation building, and he could not be promoted to the late stage of foundation building at all.

"It seems that I still underestimate the aura required by the Sky Devouring Method. Chu Chen stood up and looked into the spirit pool, only to see that there were only a few inches of spiritual water left in the spirit pool. "It will take at least a few months for the aura here to return to the way it was just now, and it seems that it will take some time for me to be promoted to the late stage of foundation building. ”

After leaving the spirit pool, Chu Chen began to turn around in the valley, in addition to the strong spiritual energy in this valley, but there is also a medicine garden and a lot of elixirs growing everywhere, this valley does not know how many years no one has come, the elixir here is a real elixir, each plant is difficult to find in the outside world, Chu Chen carefully dug it out one by one, and put it in the storage ring.

After cleaning up the elixirs scattered in various places in the valley, Chu Chen came to the medicine garden not far from the thatched house, this medicine garden is not very large, only about ten zhang in size, but there are a lot of elixirs that are difficult to find in the outside world, but most of these elixirs Chu Chen can't use on himself, because there are many elixirs that are only suitable for Yuan Infant Monks to use, if he uses them now, it will be a tyrannical thing, not to mention, the elixir in this is almost impossible to find in the outside world, even if there is, it is in the hands of the major forces, and ordinary monks can not find it at all。

Looking at the elixir in the medicine garden in front of him, Chu Chen thought about how to use it, he was still far from the Yuan Infant Stage, if he let these elixirs be placed here, it would be a waste, but if he devoured it directly, it would be even more tyrannical, and he would be struck by thunder and thunder.

"Use them to exchange what I need now?" Chu Chen muttered, this also works, it's just that this is an elixir suitable for old monsters in the Yuan Infant Stage, and it is too conspicuous to take it out, and it will be robbed if it is not good.

"Forget it, just let them continue to grow here, and use them when I reach the Yuan Infant Stage. After thinking about it for the last time, Chu Chen still decided to keep these elixirs, he walked into the medicine garden, took out the elixirs suitable for his use, and then added a ban in front of the medicine garden to hide the medicine garden, so as not to dig it up for unknown reasons when the Ke family came in the future.

Hiding the medicine garden, Chu Chen's divine sense was released, checking Ke Yongchang's situation, and after finding that he was all right, Chu Chen came to the thatched hut and found a place to sit down, now, he is already in the middle stage of foundation building, and it is much more convenient to refine the pill.

In his previous life, Chu Chen was in the realm of Immortal Venerable, and although his attainments in the Dan Dao could not be said to be at the peak, ordinary alchemists were far inferior to him.

"In the previous life, the deity went through a lot of hardships to obtain the inheritance of the God of Medicine, and made great progress in the Dan Dao, although it cannot be said to be the pinnacle of the Dan Dao, but no matter what pill is refined, there is no need to use the medicine furnace, which saves me a lot of things. Chu Chen recalled the experience of obtaining the inheritance of the God of Medicine in his previous life, and couldn't help but sigh a little, at that time, he was just a minor monk in the middle of the second step realm, secretly following a group of third-step powers to break into the forbidden land of the God of Medicine, and he didn't think about obtaining the inheritance of the God of Medicine, as long as he picked up some garbage behind these third-step powers, but he didn't expect that his spirit beast had found a shortcut, and he was the first to come to the Medicine God Temple...... Later, he was hunted down by the third step power all over the world......

Chu Chen sighed for a while, took out all the elixirs from the storage ring, and placed them in different categories, after taking a deep breath, his right hand was raised, a flame appeared in the palm of his hand, and his left hand grabbed forward, and an elixir was grabbed by him and thrown into the flame of his right palm, and then, with his left hand, he twisted the formula, and one after another the elixir was flicked into the flame, and after a few seals, he took a lot of elixir and threw it into the flame, and then several seals were played out and bounced into the flames, so after three times, Chu Chen felt that he was already familiar, so he threw several elixirs into the flames, and as his seals flicked in, these elixirs began to melt, turned into liquids, and fused with other elixir liquidsThe residue of the elixir turned into ashes in the flames, and when all the elixirs were turned into liquid and fused together, the pills began to take shape, and after almost two incense sticks, in the flames, nine snow-white pills the size of a baby's thumb appeared.

"It's still a little rusty, and with only the cultivation in the middle stage of foundation building, it's still a bit reluctant to refine the pill in this way. Chu Chen took out a jade bottle and filled the elixir with a dissatisfied expression.

If there were alchemists watching when Chu Chen was refining the pill just now, it would definitely make these alchemists go crazy, because they had never heard of it, let alone seen a person refining pills, don't use the Dan furnace, this is simply beyond their cognition! Especially when the alchemists saw that he was still dissatisfied after refining successfully, they probably couldn't help but beat him up, right?

After resting for a while, Chu Chen continued to refine the pill, it took him almost five hours to refine all the elixirs into pills, but with these pills, he couldn't push his cultivation to the peak of the late stage of foundation building, everything, and the spirit pool had to be refilled with spiritual liquid, so that he could push his cultivation up.

After receiving the elixir, Chu Chen released his divine sense again, and after seeing that Ke Yongchang was normal, he began to recover his spiritual power, and the continuous alchemy of these few hours made his spiritual power consume a lot, although the method of alchemy is easier than refining it with a Dan furnace, and the order rate is higher, but its consumption is also not small, and the alchemy of these few hours has consumed more than fifty percent of the spiritual power in his body.

After a few more hours, Chu Chen recovered his spiritual power, and his divine sense was released, only to see that Ke Yongchang had successfully broken through and was walking towards him, seeing this, Chu Chen got up, and not long after, Ke Yongchang came to him.

"Xiao Chen, thank you so much!" Ke Yongchang came up and bowed to Chu Chen.
