Empty layer.

"Hiccup~"

Yun Ze hiccuped, broke away from his cultivation state, and raised his eyes to look at Bubu on the side.

Ever since he had raised the Qi Sea to three hundred times, the effect of eating the Qi Casting Pill was very low.

After the Nine Realms of Qi Sea, eating a Nine Transformation Casting Qi Pill can only double the Qi Sea.

After reaching the three hundred times the Qi Sea, you have to eat two Nine Transformation Casting Qi Pills to increase the Qi Sea by one time.

His burps now smell like pills, and he really can't stand it.

"How many times?"

Bubu's voice sounded, and it was obvious that she had also been paying attention to the situation on Yun Ze's side.

"Three hundred."

Yun Ze replied, got up and moved his muscles: "I rested, how many days have passed now?" ”

"Three days."

"It's been three days...... Is there any news from outside? ”

Soon after Yun Ze entered the cultivation state, Bubu asked him for the jade slip.

If there is news outside, she can dock as soon as possible.

Yun Ze thought about it for a while, and finally chose to give the jade slip to Bubu, and she would connect with the situation outside.

Anyway, she still knows more about the emperor.

"They are already looking for people, and it is estimated that they will gather together in seven days to break through the foundation, and then they will start collecting a large number of Yuan Qi."

Yun Ze couldn't help frowning.

Seven days, fifty-six times.

From a purely computational point of view, this is just right, he can go out and fight with everyone.

Can...... This thing can't be calculated from a calculative point of view!

Now that he has expanded to three hundred times the sea of qi, he has already felt the limit, and every time he expands outward, it is as if he will be burst at any time.

And fifty-six times!

Even if it is theoretically possible, it may not be achieved in seven days.

Forget it, no rest!

Yun Ze gritted his teeth and sat back on his knees again, ready to stuff the Nine Turns Qi Casting Pill into his mouth.

But when he poured the aura into the Sumeru ring, the whole person was directly stunned.

Cast Qi Dan ...... The last twenty-four remained!

Before, he was taking pills while cultivating, and he didn't pay attention to the amount of pills left.

Looking at it now, there are only twenty-four Qi Casting Pills left, which is not enough to expand the Qi Sea at all!

"Let's eat first, how much can be improved."

Boo's voice rang out again.

Listening to what she meant, it seems that she has long known that the Qi Casting Pill is not enough?

Also.

Bu Bu knew the method of building the foundation of the Heavenly Dao, so he should naturally know the difficulty of expanding the three hundred and sixty-five times the Qi Sea.

She had previously given herself a part of the Qi Casting Pill, and she should be able to roughly estimate how many Qi Casting Pills she needed to achieve the consummation of the Qi Sea.

And these Nine Turns Qi Casting Pill were all 'borrowed' by her from Danzun, so she naturally knew best whether it was enough or not.

Now that she let herself eat it first, could she have any other way to help her expand her qi sea?

"Okay."

A doubt popped up in Yun Ze's heart, but he didn't think much about it, and first refined the remaining twenty-four Nine Transformation Qi Casting Pills

Twenty-four Nine Transformation Casting Qi Pills, Yun Ze took half a day to complete the refining.

Now his Qi Sea had expanded to three hundred and eleven times, and he was still fifty-four times away from the Perfection Realm!

These fifty-four times are like a moat to him!

The twenty Nine Transformation Casting Qi Pills in the front made him break through to three hundred and ten times the Qi Sea, but the four in the back only allowed him to break through to double the amount!

In other words, for every tenfold increase in the Qi Sea, the efficiency of the Nine Turns Casting Qi Pill will be doubled!

If this is the case for the rest of the day, then he needs to at least ...... Nine hundred and sixteen Nine Transformation Casting Qi Pills!

This was already equivalent to the number of all the Nine Rank Casting Qi Pills he had swallowed earlier!

Not to mention Danzun, even if it was ten Danzun, it would be difficult to refine such a number of Nine Rank Casting Qi Pills in these seven days!

What's more, I may not be able to eat so much......

God knows what method Bubu is going to use to cross this moat.

Yun Ze opened his eyes, and before he could speak, Bubu's voice sounded again.

"Finished refining?"

"Hmm."

Yun Ze responded: "It's three hundred and eleven times now, and it's really difficult to get to the back." ”

"That's nature."

Bubu got up and walked towards him as he spoke: "Since ancient times, the realm of the consummation of the sea of qi has been the dream of all ethnic groups, in addition to the need for a large number of heavenly and earthly treasures, perseverance, luck, inheritance, and talent are all indispensable!"

With your qualifications, if you put it in the clan back then, it would be the Eight Realms Qi Sea at most, and it would be a fool's dream to achieve the consummation of the Qi Sea.

It's just now...... Alas. ”

Bubu sighed, a hint of loneliness flashed in his eyes, and he didn't continue.

She walked behind Yun Ze and raised her hand to land on top of his head: "That's it, let's not talk about the past, you let go of your mind and stick to the heavenly spirit!"

Whatever happens next, don't run the aura. ”

"I want you to trust me completely, can you do it?"

"Yes!"

Yun Ze knew that Bubu would not harm himself, so he responded to what she said, let go of his mind and stick to the heavenly spirit.

Moment!

Yun Ze felt a stream of spiritual energy penetrate into his body, and spread to all his limbs and hundreds of bones at an extremely fast speed, and then it poured into the sea of qi like the confluence of hundreds of rivers!

Airplanes!

A buzzing explosion!

Yun Ze only felt that the Heavenly Destiny blood, the sword species, and the sword qi extracted from Xiao Shu's body instantly shocked!

That aura wraps these three and coordinates the oscillating frequency of the three.

It's uncomfortable!

It's like there are countless ants climbing on the soles of your feet and palms!

He instinctively wanted to mobilize his aura to remove this itch, but he could only force it with his consciousness!

Now he knew why Bubu was mentioning 'perseverance'.

Not everyone can stick to this thing!

Soon, the oscillation frequencies of the three were finally coordinated by Bubu, and the sea of qi suddenly shook endlessly!

"Poof!"

Yun Ze spurted out a mouthful of blood, and the itching was instantly dispelled, replaced by bursts of sharp pain!

It was different from the qi sea shock he had caused when he touched the sword qi before.

This time, it was a sea of qi shock caused by the simultaneous tremor of three objects, including the Heavenly Destiny Blood and the Sword Species!

It's not even an instantaneous shock, it's a continuous shock!

But the effect is also remarkable!

Even if it was three hundred and eleven times the current sea of qi, Yun Ze could feel that his sea of qi was constantly expanding at a speed visible to the naked eye!

"Hold on."

Bubu's voice sounded from the top of his head, and he trembled faintly: "For the first time, you hold on at least ten breaths!" At least 10 breaths! ”

Yun Ze could feel that Bubu was also in extreme pain.

The shock was caused by her, and at the same time controlled by her, and it was clear that she was not feeling well.

Ten breaths!

It's just ten breaths, and it's gone in the blink of an eye!

Yun Ze gritted his teeth, and kept counting down in his heart!

When the tenth breath was up, Bubu lifted his hand from his head.

Both collapsed to the ground almost simultaneously, gasping for air.

"Are you alright?"

The two spit out four words in unison and smiled at each other.

"I'm fine, but I seem to have some internal injuries, and I'm afraid I won't dare to shake the sea of qi in a short period of time." Yun Ze replied with a wry smile.

He said that it was relaxed, but in fact, the sea of qi was already full of cracks.

Fortunately, with the Heavenly Mandate Blood, he could slowly repair the Qi Sea, otherwise he would not be able to cultivate.

"Hmm."

Bubu nodded, his face was pale, and there was no trace of blood: "Don't worry, you have enough time to cultivate."

But next time, at least twenty breaths, you should be mentally prepared. ”

“…… Good. ”

Yun Ze hesitated for a few breaths, and finally reluctantly spit out a word.

Twenty breaths, God knows if he can hold it.

They are outside, and there are still six days to build the foundation collectively, and when the time comes, they are afraid that there will be another big war, and they don't know if they can catch up.

Let's see how our qi is first.

He stood up, sat down cross-legged, and sank his mind into a sea of air.

I don't know if I don't see it, and I'm shocked when I see it!

Now his sea of qi has reached three hundred and twenty times!

Ten breaths of time, a full expansion of the sea of qi by nine times!

This is equivalent to eating thirty-six Nine Transformation Qi Pills!

Yun Ze immediately opened his eyes and looked at Bubu and found that she had fallen asleep at the moment.

It seemed to be the first time he had seen Boo Cloth asleep.

Even when he first came out of Hanshan Village, when he was completely asleep, Bubu was still awake.

Looks like she's really tired.

Twenty breaths next time.

It seems that these twenty breaths are a challenge for both herself and her.

Yun Ze took a deep breath, didn't dare to delay time, closed his eyes again, and began to absorb the pure spiritual fluid in the Sumeru ring.

If you want to build a foundation for the Heavenly Dao, in addition to the consummation of the Qi Sea, you also need to reach the ninth level of Qi refining!

Now he is only in the sevenfold primordial realm of qi refining, and his cultivation has to hurry up to keep up!

When the sea of qi was repaired, Yun Ze opened his eyes again and found that Bubu had woken up.

She was sitting in place at the moment to cultivate, and when she saw Yun Ze wake up, she also opened her eyes.

"Awake?"

"Well, how long has it been outside?"

"In two days, they have already found forty-five people, and they don't plan to continue looking, they are going to let these forty-five people reach the ninth level of qi refining first.

Dustfeather said that thanks to those pure spiritual liquids, otherwise the plan might have been delayed in five days. ”

"Hmm."

Yun Ze answered, looked at Bubu and stopped talking......

"What do you want to ask, you can ask me directly, there should be no secrets between you and me."

Yun Ze couldn't help but smile bitterly: "Have you still found out?" ”

In fact, when he decided to give the jade slip to Bubu, he also glanced at the news from Yuchen Yu.

There is only one sentence on it, but it is enough to make Yun Ze's heart beat wildly!

Boobu, probably from the primeval world!

Yun Ze is not a novice who has just stepped into the cultivation realm now, so he naturally understands what Taigu means.

The history of the entire Xiuzhen Realm consists of three sections: ancient, primeval, and ancient.

The period of the ancient people in which the emperor is located is the ancient times, and the ancient times are even older than the ancient people, and the ancient times are even more untraceable, and it is said that it is related to the origin of Xiuzhen.

If Bubu was from the primeval period, then she lived at least hundreds of thousands of years from now, if not millions of years!

This terrifying existence is enough to make people's hearts tremble just by hearing about it!

It's no wonder that although she is reincarnated and re-cultivated, she doesn't know much about the current cultivation realm.

"Just ask."

Bubu smiled indifferently: "Whatever you want to know, I can tell you." ”

"You ......"

Yun Ze took a deep breath, and finally asked, "Who is it?" ”

"Actually, it's time to tell you."

Bubu seemed to know everything, and lightly opened his thin lips: "I'm from ancient times." ”
