Fortunately, at this time, the night was dark, and coupled with the accommodation area, few people would spend the night here, and Sun Yan's first forging yuan cultivation did not alarm anyone.

After a long time, a feeling of suffocation hit, and Sun Yan found that the Yuan Force around him was exhausted, and he suddenly opened his eyes.

All around, not only in the room, but also in a radius of 100 meters, the vitality has been absorbed, causing a vacuum of vitality, and the guide zhì [forging yuan jue] cannot continue.

Looking at the time, it was already three o'clock in the morning, and this time the cultivation lasted for more than four hours.

"It seems that we still have to go to the central Yuan Qi Cave, where there is abundant Yuan Qi and can support the cultivation of [Forging Yuan Jue]. ”

Sun Yan opened his inner look, examined the changes in the Yuan Force Pool in his chest, and found that in more than four hours, he had only forged less than one thousandth of the inner Yuan Force Pool of this Yuan Force Pool.

This situation made Sun Yan feel a headache, if he cultivated here, even if he didn't sleep, it would take nearly half a year to forge the Yuan Force Pool alone.

The Seven Yuan Power Pools took two and a half years to complete the first weight of the [Forging Yuan Jue].

"The concentration of the Genki Cave on the hill is 5 times higher in the first layer, 10 times in the second layer, 15 times in the third layer, 20 times in the fourth layer, and 25 times in the fifth layer......"

Sun Yan secretly calculated, and found that if he wanted to re-cultivate the first level of the [Forging Yuan Jue] within a month, he would at least have to cultivate in the Yuan Qi Cave above the sixth layer.

"Let's not talk about it, can it withstand the concentration of the sixth layer's Yuan Qi, 60 lower-level [Yuan Energy Crystals] per day, 1,800 pills a month!"

The corners of Sun Yan's mouth twitched, this is only the Yuan Energy Crystallization required for the first weight of the [Forging Yuan Jue], what about the second and third levels? When it comes to impacting the tenth-level martial realm and rebuilding the martial foundation, the process of forging the Yuan again will definitely cost more. No matter how you calculate it, you need a massive amount of [Yuan Energy Crystals], which is a bottomless pit.

Thinking of this, Sun Yan picked up the little puppy Lele and rubbed the little guy's furry skin, "Lele, I'm so poor! ”

"Make money, make money! Eat meat, eat meat. The little guy was immersed in his sleep and muttered Sun Yan's words.

In the end, Sun Yan decided to go to the Yuan Qi Cave to cultivate first, anyway, there were still a lot of Yuan Energy crystals on his body, which could support him for a while.

......

In the early morning, the sky was bright, and in front of the hill in the center of the base, Sun Yan hurried over.

At the entrance to the Genki Cavern, there is a base member guarding it, number 666.

After a few conversations with No. 666, this person was very easy-going and knew everything about Sun Yan's problems. After talking, Sun Yan realized that guarding the entrance of the Yuan Qi Cave can also earn Yuan Energy Crystals, 3 lower-level [Yuan Energy Crystals] every day, and the Yuan Qi on the periphery of the hill is also very strong, which is very suitable for cultivation, which can not only earn Yuan Energy Crystals, but also not delay cultivation, killing two birds with one stone.

"Brother No. 666, he is really calculating, he is really a model for my generation!" Sun Yan sincerely admired, he did not have such a calculating mind.

"Alas, No. 998, you are a newcomer, I don't know the situation! A martial arts talent like me is relatively average, going out to sea to hunt, nine deaths, or guarding the entrance of the cave here, it is the safest!" No. 666 imparted his experience for many years.

The two teased for a while, Sun Yan entered the small mountain area, and he didn't look at the Yuan Qi Cave on the three floors below, and walked straight towards the fifth layer.

On the fifth layer of the hill, there were more than 100 Yuan Qi caves, half of which were empty, Sun Yan chose one and entered it immediately.

In the distance, No. 666's eyes were sharp, he could see clearly, and he shook his head and sighed lightly: "This No. 998 is too confident, he chose the fifth-layer Yuanqi Cave for the first time, he is a ninth-level martial artist, even if he is excellent, it is estimated that he will not last for three days." Alas, I was too young in the end, and I thought I was the same at the beginning. ”

The martial artists who can enter the starry sky battlefield are all famous martial arts geniuses on a certain planet, confident and proud, and when they first come to this base, many people will choose to start cultivating directly from the third layer.

However, at the beginning, there were very few who could cultivate for a long time above the third layer.

Sou!

A cold air surged, and Shi Yiqin's figure appeared in front of No. 666, and the ground around him was immediately covered with a layer of frost.

"Oh, Miss Yiqin, you just came out of the Yuan Qi Cave yesterday, and now you have come to cultivate again? It seems that soon, you will complete the three forgings and go to Fengyun City. No. 666 said with a smile.

She had a cold face and said, "No. 666, which newcomer did you say entered the fifth layer?"

"Hehe, it's the number 998 who made an appointment with you. He also knew that his strength was insufficient, and it was estimated that he wanted to do his best to cultivate the first level of [Forging Yuan Jue], so he directly chose the fifth layer of the Yuan Qi Cave. "No. 666 knows everything, it's not a secret, he has nothing to hide.

"The fifth floor?"

Looking at the mountainside of the hill in the distance, Shi Yiqin sneered, "It's so ambitious! Don't cultivate to the fifth layer until you are seriously injured, your strength is not as good as yesterday, it will be too boring." ”

As soon as her delicate body moved, Shi Yiqin flew away and flew into a vitality cave on the fifth floor. With her current strength of the second level of [Forging Yuan Jue], she can only cultivate in the Yuan Qi Cave of the fifth layer, and her thoughts are the same as No. 666, this No. 998 will not be able to withstand it for three days at most, and it will roll out from the fifth layer.

......

As soon as he entered the fifth-layer Yuan Qi Cave, Sun Yan placed 50 lower-level [Yuan Energy Crystals] on the grooves in the wall.

Bang, the cave was automatically sealed, and the strong vitality quickly gathered, reaching 25 times that of the accommodation area. Huhu, the Yuan Qi actually formed a cyclone, hovering in the center of the cave, and its intensity was not at all something that ordinary ninth-level martial artists could bear.

Walking to the center of the cave, which is also the center of the cyclone, this position is the place where the vitality in the cave is the strongest, Sun Yan closed his eyes and felt the huge pressure around him.

Such a strong Yuan force, like the water pressure in the deep sea, squeezed Sun Yan's bones crackling. Fortunately, with his current physical strength, he can barely withstand it.

"Good place! Fortunately, I didn't choose the sixth layer, with my current body, it is estimated that I can't withstand the pressure of the sixth layer. At least two forging elements of the Yuan Force Pool must be completed before you can try. ”

At the center of the cyclone, Sun Yan stood firm, sat down slowly, his body completely relaxed, and began to run the first key of [Forging Yuan Jue].

Boom, like the sound of ten thousand horses galloping, Sun Yan's body seemed to have become a blower, and the strong vitality frantically poured into his body, quickly making up for the loss caused by the forging yuan.

In this process, Sun Yan felt that with the crazy influx of vitality, his body seemed to have undergone another forging, and the crazy vitality was like a knife, constantly twitching in the skin, flesh, muscles and bones.

This kind of suffering, I am afraid of falling into hell, is nothing more than that.

It hurts, it hurts!

Sun Yan's body trembled slightly, and a layer of fine sweat oozed from the skin of his whole body, scarlet, it was blood sweat!

This kind of pain is almost catching up with the process of taking [fading body fluid] when I was a child.

It's just that this time the pain is to become stronger!

Time passed minute by minute, Sun Yan sat quietly in the cave, and he didn't know how long it took, the vortex formed by the vitality gradually weakened, and it was only half the size of the beginning.

At this time, the puppy Lele woke up from sleep, it raised its little head, looked left and right, and saw that the master was cultivating, and it was running to the door of the cave as usual, and did a good job of guarding.

However, the strong vitality that filled this cave made Lele feel very comfortable, and the Heavenly Wolf had no resistance to pure energy matter.

"Suck!" the little guy couldn't help but take a sip.

Suddenly, the vitality vortex that was originally hovering in the center of the cave was sucked half by the little guy, wrapped around Lele's small body, making it feel warm and closed its eyes comfortably.

After a long time, the concentration of vitality in the entire cave fell back to the beginning, Sun Yan seemed to feel it again, opened his eyes, and when he entered his eyes, he happened to see Lele absorbing the vitality around him, and the little guy was still half-asleep, and let out a moan pleasantly.

Seeing this scene, Sun Yan's face darkened, he hurriedly looked at the time, and then examined the situation in his body, and suddenly found that it was more than four hours, and the inner yuan forging of the Yuan Force Pool in his chest was pressed by one-thirtieth.

However, the 50 lower-level [Yuan Energy Crystals] on the cave wall had been depleted, and the concentration of Yuan Qi around them had returned to normal.

After thinking about it for a while, Sun Yan wailed, the progress of his cultivation at the fifth layer was far beyond his expectations. At this rate, if you practice without sleep, you can complete the forging of a Yuan Force Pool in about 5 days.

However, after being divided by Lele and losing part of the vitality, 50 lower-level [Yuan Energy Crystals] could only last for more than 4 hours?

Doesn't that mean that if you want to cultivate here for one day, you have to spend 300 lower-level [Yuan Energy Crystals]?

At this time, Lele woke up from a deep sleep, shook his head, and saw that the master was looking directly at him, it was very clever, and immediately drooped his head, "Master, I was wrong! I won't absorb the vitality indiscriminately next time." ”

"You little thing, don't pretend to be innocent to my brother...... Sun Yan scolded with a smile, how could he blame Lele for this matter.

Walking over and picking up Lele, rubbing its little head, Sun Yan frowned: "Even if you don't divide the vitality, the low-level yuan energy crystals consumed every day will probably exceed 150." If you want to cultivate to forge the Yuan One Heavy, it will take at least 35 days, close to 5,000 lower-level [Yuan Energy Crystals]. ”

In this way, the Yuan Energy Crystallization borrowed from Chief Le could only last for a month. If Lele divides the Yuan Qi again, then in a month, the required lower-level [Yuan Energy Crystals] will exceed 10,000.

For the current Sun Yan, this is a huge amount of money!

After thinking for a while, Sun Yan made a decision, first finished forging the seventh yuan power pool in his chest, and then went to the warehouse area to see how to earn yuan energy crystals, and by the way, he exchanged all those yuan energy crystals on his body.

At this moment, Sun Yan realized what Chief Le said, in the starry sky battlefield, the three most important things are to earn Yuan Energy Crystals, fight and cultivate.

In the groove of the mountain wall, 50 lower-level [Yuan Energy Crystals] were placed, and the Yuan Qi Vortex converged again, this time, Sun Yan left Lele by his side, and one person and one dog entered the cultivation state at the same time.
