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

Rumble!

Rumble, rumble!

Outside, the sound of thunder rumbled.

"Oh ho?"

Xu Chengxian, who was boredly digging pits and refining spirit stones at the bottom of the cave, immediately widened his eyes when he heard the sound.

He perked up instantly.

Who is undergoing tribulation?

Could it be those two from his family?

The Second Sister, the Empress?

Or the Third Brother, the Dao Lord?

He had refined more than forty low-grade spirit stones!

There was nothing else to do after eating his fill.

"Without a phone to pass the time, sleeping doesn't even increase my blood energy anymore. I'm so bored that I'm about to start cultivating!"

Fortunately, he didn't learn the cultivation technique.

However, he learned a few minor spells.

He could perform them by pinching his fingers and chanting incantations, and he looked quite the part.

It's just that spells require mana, which is the mobilization of heaven and earth spiritual energy with demon power or spiritual power. He doesn't have demon power, so using blood energy is not smooth enough.

Of course, Xu Chengxian didn't care, as he was just using it to pass the time anyway.

More than two months ago, his blood energy value exceeded ten million.

Originally, he wanted to be cautious and stop temporarily when it reached ninety million.

He wanted to wait for Lingxiao and Ling Yunzi to reach the Great Demon Realm first.

It wasn't that Xu Chengxian developed a sense of filial piety, feeling that he had been suppressing his younger sister and brother, and worrying that the Empress and Dao Lord's Dao hearts would be damaged.

Not to mention that the two of them had strong minds and showed no signs of discouragement, he didn't have the delicate thoughts of a good older brother.

The main thing was that he hadn't undergone the thunder tribulation and didn't know its power.

He was worried about being struck to death by lightning.

He wanted to observe it to be mentally prepared.

Although Lingxiao had undergone a thunder tribulation before, who knew if the Transformation Thunder Tribulation and the Great Demon Thunder Tribulation were the same?

This was a matter of life and death, so it was right to be cautious and prepared.

It was that thunder tribulation that made Xu Chengxian deeply realize that he still had to have some reverence for the power of heaven and earth.

But he didn't expect that he would sleep right through it!

His blood energy exceeded ten million and went over by several thousand.

Fortunately, it didn't immediately trigger the thunder tribulation.

It was at this time that he had a flash of inspiration and remembered that Ling Yunzi and the others had mentioned several times that they wanted to use demon power to trigger heavenly thunder.

In other words, there might be a grace period.

Two days later, Xu Chengxian noticed that the demon power fluctuations on Lingxiao's body had changed.

It became more profound, with a faint sense of vastness.

The power had undergone a change in level.

If he had to describe it, it was probably like transforming from clouds to water?

Then, Lingxiao began to constantly condense her divine sense, suppressing the fluctuations of demon power on her body, and no longer released her demon core when refining moonlight at night.

At this time, Xu Chengxian realized that she had also broken through to the Great Demon Realm.

As expected of the Empress of the previous life.

She was only a few days later than him.

Then, a few days later, mana fluctuations also came from Ling Yunzi's cave.

This guy had also entered the Great Demon Realm.

In human form, that is, with an innate Dao body, coupled with the cultivation of top-notch techniques and the experience of the previous life, their cultivation speed was simply like leaping into the sky.

It only took them more than two years to go from the eighth level to the Great Demon Realm.

"What do you mean, crossing from the ninth level to the Great Demon Realm within ten years is considered a top-notch talent among the demon race?" Xu Chengxian thought. Isn't that just praising themselves in disguise?

Of course, he was still faster.

But at the same time, he also felt a sense of crisis.

These two guys are catching up too quickly.

But when he thought about how he had also used blood energy to improve his innate supernatural powers twice in the middle, and now he could directly refine flesh and blood and demon energy, he felt a little relieved.

Big brother is still big brother.

Big brother was born first, big brother hatched first, so big brother is destined to be one step ahead.

Empress and Dao Lord?

Those are all things of the previous life.

However, this time is an exception.

The big brother who hasn't undergone the thunder tribulation decided to let the experienced younger sister and brother go first.

Rumble!

Rumble!

Several lightning bolts split the dark clouds.

"You guys can really endure!" Xu Chengxian couldn't help but sigh as he looked at the thunderclouds in the sky.

Because he didn't know how long the grace period for the tribulation was, or whether it was related to the increase in blood energy.

But seeing Ling Yunzi and Lingxiao suppressing the fluctuations of demon power, he guessed something.

So, he didn't dare to sleep next.

He was afraid that he would be struck by lightning while sleeping, and be fried to a crisp.

A snake life that had been sleeping and eating all the time suddenly lost the option of sleeping, which made him so bored that he felt uncomfortable all over.

He even ran to Lingxiao's training ground and wandered around several times.

He was almost biting his own snake tail and playing the Snake game.

But he couldn't urge Lingxiao and Ling Yunzi.

From their reactions, it could be seen that they were obviously accumulating strength.

One is an Empress and the other is a Dao Lord, they know when to undergo the thunder tribulation.

Besides, the thunder tribulation is not a joke. He wanted to sponge off their experience and still urge them, which was a bit too shameless.

No matter what, in this life, he is their biological older brother. - Whenever he had thoughts that were too animalistic, Xu Chengxian would persuade himself like this.

Bored?

Then refine spirit stones and count the scales on his body again.

However, the latter requires concentration and tranquility, otherwise, it's easy to get sleepy!

...

Finally!

Finally!

Lingxiao is finally going to undergo the tribulation!

He finally waited for this day!

At this time, the dark thunderclouds were surging like a thousand troops and horses.

The rumble was continuous.

The thunderclouds were layered upon layered, black and deep, as if a god or demon awakened from the depths of the nine heavens, roaring angrily.

At this time, it was noon.

The sky-covering dark clouds swallowed the daylight.

Each dark cloud was like overlapping mountains, carrying an irresistible force, slowly and firmly pressing down on the earth.

The air was filled with an extremely oppressive atmosphere, as if even breathing became heavy.

The thunder was quietly brewing in this oppression.

At first, it was a low rumble, like an ancient beast turning over in its sleep. Gradually, the rumble became louder and louder.

It was as if it was about to tear a hole in the sky and release something even more terrifying.

Crack!

In a flash of lightning, a bolt of lightning streaked across the sky.

Silvery white and fiery, it illuminated this world shrouded in darkness.

"Holy crap!"

When Xu Chengxian rushed out of the cave and flew towards the place Lingxiao had chosen for the tribulation—a valley far away from their spirit vein.

Looking up and seeing this scene, his scalp tingled.

He couldn't help but stop moving forward.

Lightning, of course, was not enough to scare him, but the residual power of the lightning exuded an aura that made his heart palpitate.

"Concentrate, calm down."

Ling Yunzi appeared beside him, "Don't let the thunder tribulation haven't even arrived, and your divine soul is already frightened and unstable."

He felt very strange about Xu Chengxian's reaction, "You've been through it before, why are you so nervous?"

"..." Xu Chengxian thought, you might not believe it if I told you, but I really haven't been through it.

But no, he can't say that.

It's easy to get exposed.

So, he laughed and said, "It's been too long, I don't even remember."

Then he quickly added, "Yunzi, can your Second Sister handle this thunder tribulation?"
