Sleeping for a second increases my blood energy. I become the strongest sky-swallowing snake

"Huh? Why did they leave?" Xu Chengxian blinked.

They were just talking so nicely, why did they suddenly leave?

Why the rush? What's the emergency?

"Did I say something they didn't like?"

But he didn't say anything much, and everything he said was the truth.

"Forget it, I'll go too."

Time to go back to sleep.

He needed to quickly advance to the ninth rank.

Only by advancing to a ninth-rank demon beast could he learn the conditions required to cultivate to the next stage.

As Xu Chengxian swam, he pondered that he could now obtain ten million units of blood essence in about four months.

The amount of blood essence required for a demon beast to advance in rank, from low to high, is much higher with each rank than the previous one.

Almost doubling the increase.

"After advancing to the ninth rank, the blood essence needed for the next realm shouldn't exceed fifty million, right?"

That would require sleeping for… almost twenty months.

Including the time he inevitably had to wake up in between.

It would probably take close to two years.

"Tsk." Xu Chengxian didn't really care.

He was just a little worried about Ling Yunzi.

"Can Yunzi transform within three years?" Thinking of this, he glanced at the mid-grade spirit stone.

After thinking about it, he decided not to use it yet, and wait until the ninth rank.

After the advancement of his innate divine ability, the speed at which his breath refined spiritual energy and improved his divine soul realm was even faster than before.

But he didn't cultivate any techniques.

If he couldn't swallow the spirit stones, he couldn't use his innate divine ability to refine them, so he could only shatter them and let the spiritual energy dissipate.

Then he would inhale it into his body with his breath and slowly refine it with his blood essence.

"Or, should I swallow it in big gulps?" Xu Chengxian's mouth twitched.

A thick, big patterned snake, with bulging eyes, opened its mouth wide, constantly sucking in air, and then swallowing it down.

…The scene was too beautiful, and very stupid.

And very wasteful.

Wasting spirit stones, and also wasting sleeping time.

It would be better to give them to Ling Xiao or Ling Yunzi and have them exchange them for other things.

So he was inclined to give the spirit stones to his Daoist brother.

No matter what.

Sending a Daoist to be a live-in son-in-law, this spectacle, I still really want to see!

"Hehe ~"

A snake's life shouldn't just be about eating and sleeping, and sleeping and eating.

Occasionally, one has to find some fun.

Besides, what's the point of always staying in a small mountain ditch?

Going to the royal city of the demon race would broaden his horizons.

As Xu Chengxian thought, he passed by the cave hall where Bai Xiaocui was, and released his divine sense to take a look.

The big white snake had just advanced to the sixth rank and was stabilizing its blood essence, cultivating its demon power to condense its own demon core.

Observing the fluctuations of demon power around it, and the flow of blood-fiend energy, it seemed to be going smoothly.

Inside the adjacent cave, Dai Dai was fast asleep.

It had grown another circle.

The spirit-gathering array, arranged with spirit-gathering grass and spirit-locking grass, concentrated the spiritual energy in the cave and prevented it from dissipating.

The spiritual energy rolled, forming a spiritual mist, enveloping it and the spiritual plants on its back.

Da Sheng curled up into a fur ball, sitting in the middle, five hearts facing the sky, obviously cultivating.

There were also two more pieces of land, stained with beast blood.

Planted inside were two Ning Shen flowers and two Netherworld Spirit Mushrooms.

They hadn't sprouted yet.

The former were the mission rewards obtained for urging Ling Xiao to transform and helping Ling Yunzi refine pills.

The latter was from killing Wu Shan.

Although Wu Shan was ultimately killed by General Yu, the rewards given by the system were issued without any discount.

Including the refinement points.

"System, all the refinement points, as before, directly use them all to improve my realm."

Returning to his own cave hall, Xu Chengxian moved his mind.

【Yes, Host.】

Then, he closed his eyes and fell asleep.

At the same time, he activated the newly advanced innate divine ability—Devour and Refine.

The familiar white noise sounded in his ears.

【Blood Essence +1+1 + 1…】

【Physical Realm +1+1 + 1…】

【Blood Essence +1+1 + 1+1…】

【Divine Soul Realm +1+1 + 1…】

…

The flesh and demon power swallowed from Wu Shan hadn't been completely refined yet.

So the content of the white noise accompanying sleep had a little more layering.

However, this didn't affect Xu Chengxian's sleep quality.

…

"Ooh!"

"Damn?"

More than ten days later.

Xu Chengxian completely refined the flesh and demon power he had swallowed during the great battle with Wu Shan.

He stretched his long body and found that the injuries on his body had almost healed.

It was just that when he stretched his body, he found that the cave hall seemed to have become cramped again.

"First of all, a spacious cave hall won't shrink on its own." He stretched out his snake tail and tapped the back wall of the cave.

Confirming this point.

But this action was completely unnecessary.

Because he had just used the word 'again,' which meant that this wasn't the first time he had made this discovery.

"Aiyo! This old man has grown again!"

It was just that this time, the interval was a bit short.

Great demon, great nourishment!

Xu Chengxian very naturally estimated in his heart how long this cave hall could accommodate him if he continued to grow like this.

Then he came to a conclusion.

"At most, I can last until the ninth rank, then I'll have to find another residence."

So, he had to consider urging his younger empress sister to build a cave mansion as soon as possible.

At this time, he heard movement outside, it seemed they were discussing the construction of the cave mansion.

Xu Chengxian immediately swam out, ready to participate in the construction of the new home.

And seeing him appear, Ling Xiao was suddenly startled:

"Old ghost, why did you come out?"

Ling Yunzi heard this and suddenly turned around, looking at him with bright eyes.

"Ah? Can't I come out?" Xu Chengxian was stunned, what's wrong?

What happened?

Can't he come out?

"You, have you advanced to the ninth rank?" Ling Xiao asked.

"Huh? Of course not yet." Xu Chengxian replied.

As soon as he finished speaking, he immediately heard several breaths of air.

Vividly showing what it meant to breathe a sigh of relief.

"…Good fellows." Xu Chengxian immediately laughed, "In your eyes, I won't come out of my den unless I advance?"

How come I didn't know that I had established such a strong character setting?

"Look how scared you are." He waved his snake tail, "Advancing to the ninth rank, how can it be so easy? It's still very early."

"Then why did you come out?" Ling Xiao raised an eyebrow.

It wasn't that they were making a fuss, it was just that this flower snake had never liked to pay attention to other trivial matters.

He only cared about sleeping and eating.

Eating and sleeping, sleeping and eating.

Then he would notify them of the news of his successful advancement.

At other times, you couldn't see his踪影.

"I just woke up and heard you say that a new cave mansion was going to be dug, I wanted to make a small suggestion," Xu Chengxian said.

"Oh? You want your cave mansion to be particularly large, right?" Ling Xiao smiled, "I know what's on your mind, don't worry."

She knew why the fat flower snake had run out.

From urging her to transform, to collecting spirit stones, to looking for spirit veins, he had shown unprecedented enthusiasm.

It was all for the sake of having a large enough cave mansion in the future.

"Yes, yes, yes! That's the thing!" Xu Chengxian smiled, "Also, how long will it take to build our cave mansion?"

It had to be quick, otherwise, this place wouldn't be able to hold him!
