The entrance to the cave is connected to an underground river, whose water flows out of the surface through guò, where it converges into a pool of water overflowing to form a mountain stream.

Qin Tian's divine sense extended along the entrance of the cave, but unfortunately, he didn't find anything until the limit of his divine sense's exploration.

"It seems that you can't go into the water anymore!

With a bang, Qin Tian jumped into the pool, and soon dived to the bottom of the pool, without the slightest hesitation, he drilled into the hole of the underground river, and moved forward quickly.

Qin Tian could clearly feel that there was more and more spiritual energy contained in the river water.

I don't know how far I swam, Qin Tian estimated that it was three or four thousand meters, and he still hadn't reached the end, but fortunately, he was a cultivator, and he could hold on for a long time in one breath.

Finally, just as Qin Tian continued to swim hundreds of meters, he finally felt the source of the aura.

Crash!!!

The calm water suddenly splashed, and a figure came out of the water, it was Qin Tian.

The concentration of aura here is dozens or hundreds of times thicker than that in the basement, if you can cultivate here for a month, you will definitely be able to break through to the sixth layer of qi cultivation realm!"

As soon as Qin Tian came out of the water, he immediately felt an extremely rich aura rushing towards him, and he couldn't help but take a big breath, and immediately there was a rolling aura being sucked into his body, and as soon as the "Mixed Yuan Decision" turned, the aura was refined, and the true qi in his body increased a lot!

Raising my eyes, I saw that this was a space of dozens of square meters, I don't know where the light came from to illuminate the cave, there was nothing in this cave, only the rich and refreshing aura.

"Is this, Spiritual Liquid!? and Spiritual Spring!?"

Qin Tian stared blankly at a depression in the ground in the center of the cave, about the size of a bowl, like a jade bowl buried in the soil, and there was a small shallow pool of jade liquid in the jade bowl, crystal flowing, and countless rich spiritual energy emanated.

When the general monk absorbs the aura of heaven and earth to cultivate, there are often some impurities mixed in the aura, and it is often necessary to refine the impurities in the aura, otherwise the impurities accumulate too much, which will affect the monk's cultivation speed, and even the cultivation will regress.

And because the spiritual liquid is highly condensed by spiritual energy, it is pure and flawless, and does not contain a trace of impurities, and the monk can directly absorb the spiritual liquid to cultivate without refining impurities, and the speed is doubled, and the effect is better.

As for the spiritual spring, it is even more precious, after all, the spiritual liquid is a disposable product, and when it is used up, there will be no more, but the spiritual spring can continuously produce spiritual liquid, and the value is countless times that of the elixir!

"I didn't expect there to be a spiritual spring here, no wonder it can breed such a huge and lush forest! Hmm? It's a pity, this spiritual spring is about to dry up, no wonder there is so little spiritual liquid in the spiritual spring!" Qin Tian's face suddenly changed a lot of joy, but it turned out that he found that this spiritual spring was about to dry up.

However, Qin Tian's heart was still very happy, after all, he was definitely very lucky to be able to find a spiritual spring on the earth where the spiritual energy was so thin, and with the spiritual liquid in this spiritual spring, it was enough for his cultivation realm to break through to the sixth level of qi cultivation, or even higher!

Qin Tian opened the storage bag, and was just about to take out a jade bottle from the storage bag to collect the spiritual liquid, when suddenly a golden light flew out of the storage bag, suspended in mid-air, dripping and turning.

"Golden Eggs!?"

Qin Tian looked at the object suspended in mid-air in surprise, it was an egg, an egg with a golden body, as if it was made of pure gold, the golden light was brilliant and eye-catching.

Qin Tian once saved the child of a giant ape in Shennongjia, and this golden egg was given to Qin Tian.

At that time, when Qin Tian got this golden egg, he felt a very weak life fluctuation from this golden egg, although this life fluctuation faintly seemed to disappear at any time, but he had a tenacious will, as if even if countless years passed, this life fluctuation would still not die and disappear!

Qin Tian wanted to know what the life in this egg was, and what kind of life could survive after countless years, but unfortunately he didn't know how to make the life in this egg fluctuate and grow.

Therefore, after getting this golden egg, Qin Tian always took it with him, and later refined the storage bag, so he put the golden egg in the storage bag.

Unexpectedly, this time when the storage bag was opened, the golden egg would automatically run out!

The golden egg is suspended in the air above the spiritual spring, as if turning into a typhoon eye, the aura in the cave is pulled by the golden egg, and they are surging towards the golden egg, and the whirring wind blows, forming a whirlpool of spiritual energy.

Countless spiritual energy surged, the golden egg seemed to have become a gluttonous beast, opened its huge mouth, and swallowed the rolling aura, a faint golden light circulated on the surface of the golden egg, and a pattern containing infinite mysteries appeared, and the runes were dark and bright, as if it was the breath of life in the egg, and between one breath and one breath, a large amount of spiritual energy was swallowed.

Moreover, as time passed, the golden light gradually became stronger, reflecting the entire cave in gold, and the surrounding walls seemed to be made of gold.

Qin Tian could feel that as more and more aura was absorbed, more and more patterns appeared on the surface of the golden egg, and the life fluctuations that were originally extremely weak were gradually increasing, and the suction power coming out of the golden egg was also becoming more powerful, countless aura was being pulled, and the whirring wind in the cave was getting louder and louder.

A few breaths less, and the aura in the cave was swept away by the golden egg.

Bang!bang......

The spiritual liquid in the spiritual spring flew up, drop by drop, and turned into a rolling aura, and the aura was swallowed by the golden egg whale like a column of water, no matter how much aura, all of them were swallowed up by the golden egg!

"My spiritual liquid!" Qin Tian's heart ached, the speed at which the golden egg was devoured was too fast, and before he could react, the spiritual liquid in the spiritual spring had already been swallowed by it.

"Fortunately, there is still Lingquan, otherwise I really didn't have anything to catch this time!"

Before Qin Tian could rejoice, he saw the golden light of the golden egg blooming, and suddenly the swallowing power coming out of the golden egg was even stronger, and a huge aura gushed out from the spiritual spring, like a fountain, and the spiritual energy contained in the spiritual spring was continuously extracted and devoured by the golden egg, strengthening itself!

"Damn, this spiritual spring has been basically depleted, and now it is swallowed by the golden egg like this, I am afraid that it will not be long before the spiritual spring will be completely depleted, and the spiritual energy contained in it will be devoured, and I will really have no benefit!"

Qin Tian hurriedly sat down cross-legged, his luck cultivation technique to absorb aura, but it was a pity that the swallowing power of the golden egg was too strong, even if he operated the "Mixed Yuan Jue" to the limit, he would only be able to absorb a small amount of aura.

It's not that the "Mixed Yuan Jue" is too bad, but Qin Tian's strength is too weak, and he doesn't have that strength.

"Not enough, not enough! More than that!"

There was a fluctuation in the golden egg, but for some reason, Qin Tian understood the meaning of this fluctuation, it also needed more spiritual spring spiritual liquid to restore the vitality lost in the endless years, so that it could continue to grow and grow into a complete life, and break out of the egg.

The spiritual spring that Qin Tian discovered was already at the point of exhaustion, and not long after the golden egg was devoured, the spiritual energy contained in the spiritual spring was swallowed up, and there was not a single drop left!

At this time, the life fluctuations coming out of the golden egg were several times stronger than at the beginning.

However, Qin Tian could feel that the terrifying vitality of the life conceived in the golden egg had not yet been completely restored, and he still needed to devour more spiritual liquid spiritual springs before he could recover the lost vitality and continue to grow and finally break the shell and be born!

The golden egg devoured and absorbed the spiritual liquid of the spiritual spring, suspended in mid-air and dripping and turning, like a golden eggshell flowing with golden light, illuminating the cave into gold, exuding a faint breath of life, although this breath of life is weak, but it gives people a feeling of fierceness, as if a giant beast of the wilderness is growing in it!

Whew――

The golden egg brilliance converged, and then a golden trajectory fell into Qin Tian's hand.

Qin Tian looked at the golden egg in his hand and wanted to cry without tears, it was rare to find a spiritual spring, and before he could get any benefits, the spiritual spring spiritual liquid was swallowed up by the golden egg.

Putting the golden egg into the storage bag, Qin Tian left the cave.

............

Time flies, and more than a week has passed in the blink of an eye.

The battle with the thin old man made Qin Tian know that his strength was still very weak, and there were still many people on the earth who were stronger than him, so during this period of time, Qin Tian cultivated harder, his true qi became more and more vigorous, and his cultivation was naturally rising.

"Is there any way to speed up your cultivation?"

Qin Tian pondered for a long time, and suddenly remembered that the elixir was also an important resource needed for the cultivator's cultivation, with the aid of the elixir, the cultivator's cultivation speed could be increased a lot, and he happened to get an alchemy furnace in the ancient tomb.

However, if there is an alchemy furnace, you also need alchemy materials, otherwise it will only be difficult for a good woman to cook without rice!

Qin Tian thought about it, so he called Ye Jun and asked him to help collect some medicinal materials for alchemy, and Ye Jun readily agreed.

What Qin Tian wanted to refine was an elixir called Qi Nourishing Pill, which was a kind of elixir needed by Qi Cultivation Realm cultivators, and it was a low-level elixir, so the requirements for medicinal materials were not very high, even on the earth where the spiritual energy was thin, the materials for refining the Qi Nourishing Pill could be collected.

However, although they could be collected, some of these medicinal materials were still very precious, even if Ye Jun had great energy, it still took more than a week to gather all the medicinal materials that Qin Tian needed, and it was only enough to refine two furnaces of Qi Nourishing Pill.

Opening the storage bag, Qin Tian took out the alchemy furnace he had obtained in the ancient tomb, more than twenty centimeters high, bronze color throughout, and patterns appeared on the surface, faintly forming six rounds of suns, shining on the heavens and the earth.
