I let you have children and you lead seven sinful girls to rebel?

The first hurdle is to train endurance.

The second challenge is fire.

The third challenge is water.

The fourth challenge is lightning!

Before them stretched an endless expanse of blue ocean.

Of course, this vast ocean is not seawater, but a sea of ​​lightning formed by countless bolts of lightning.

"There's a monument there!"

The Buddha pointed ahead and there was a stone tablet.

The instructions for passing the fourth level are engraved on it.

Passing the fourth level is actually quite simple; just stay in the sea of ​​lightning for ninety-nine days.

The deeper one goes into the sea of ​​lightning, the stronger the power of the lightning becomes, and it is divided into ten levels.

The outermost blue lightning is naturally the weakest; a strong Great God Emperor can withstand it, but a weaker one cannot.

If any emperor wants to be a slacker, he can find a corner to hide in the outermost blue lightning and stay there for ninety-nine days before heading to the fifth level.

Additionally, after passing the fourth level, you will receive a lightning crystal.

The outermost blue lightning naturally forms the weakest blue lightning crystal.

The deeper you go, the stronger it gets.

Anyway, the Thunder Sea is divided into ten levels. The higher the level you can withstand, the stronger the lightning crystal you will get.

This lightning crystal will be of great use when I undergo the Quasi-Supreme Tribulation in the future.

After absorption, it can resist the effects of heavenly lightning and become stronger.

"Let's go, let's see how many levels of lightning you can withstand."

Chen Xuan chuckled and stepped inside, followed closely by the others.

Crackling!

As soon as he entered the sea of ​​lightning, blue lightning struck him fiercely, making a crackling sound.

However, this level of lightning was nothing to Chen Xuan; it was even less painful than a slap from Dugu Rou.

Chen Xuan didn't react at all.

However, the others did not fare so well. Apart from Dugu Rou and the Yellow Spring Emperor, who possessed a quasi-supreme physical body, the others clearly had to use their divine power to resist.

As for those ten Great God Emperors, they have only just begun, so they must be treated with utmost seriousness.

This blue lightning was like a tribulation for them, something they had to take seriously!

“We’re going in. If any of you ten can’t hold on, then back out. It’s not shameful to fail.”

Chen Xuan addressed the ten Great God Emperors.

Once you leave this dangerous place, it's as if you've failed your attempt to become an emperor.

Then they will be sent directly back to the Yin-Yang realm.

In fact, if Chen Xuan wanted to, he could directly use the Lightning Law to separate the blue lightning from them, easily allowing them to sneak into the fifth level.

However, Chen Xuan felt it was unnecessary.

I can't always be their protector; they have to walk their own path.

If you have the ability, then stay.

If you don't have the ability, going back to cultivate yourself as soon as possible might not be a bad thing.

"Senior Chen, please rest assured, we will definitely not let you down!"

The ten Great God Emperors clasped their fists in unison, their expressions solemn and their attitude resolute.

"Very good, I hope to see each of you in the fifth level."

Chen Xuan patted each of them on the shoulder to encourage them.

After that, about fifty of them remained and went inside.

Lei Hai's lightning power is divided into ten levels.

The outermost ring is the first layer, and its color is light blue.

Further in, the second-stage lightning had turned dark blue.

The power of the lightning was significantly stronger than that of the light blue lightning.

Several emperors have already shown signs of strain.

Of course, this level of lightning power was still like a mosquito tickling an itch for Chen Xuan—it was neither painful nor itchy.

In the end, of their fifty people, five remained at the location of the deep blue lightning on the second level.

The remaining people proceeded to the third level.

The color of the lightning had turned cyan.

More and more people are finding it difficult.

Finally, in the third phase, the blue lightning left behind twelve people.

Their team has thirty-three members remaining.

The fourth-order lightning turned golden, its power increasing even further.

There were a total of twenty-three people left on this floor!

Chen Xuan's team has only ten members left, including himself!

The fifth-tier lightning turned dark gold.

As they went deeper, the lightning struck him, and Chen Xuan no longer felt like he was being tickled; instead, it began to feel like he was being bitten by ants, which was quite uncomfortable.

Five more emperors remained here, as their strength prevented them from going any further.

In fact, these five people felt that they might not be able to hold out on the fifth level for ninety-nine days and would be forced to retreat to the fourth level.

Chen Xuan certainly wouldn't stay here just to wait for them.

They went up to the sixth floor.

At this point, their team from the Yin-Yang realm was down to only five people.

They are Chen Xuan, Dugu Rou, Qing Susu, the Buddha, and the Yellow Spring Emperor!

The lightning on this level has turned red.

"Amitabha Buddha, it seems this is my limit!"

The Buddha sighed, realizing he could not go any deeper.

"It seems this is my limit."

Qing Susu couldn't help but sigh.

One of them is the successor of the Western Venerable, and the other is the successor of the White Venerable. The fact that they were able to survive this ordeal already shows that they are much stronger than others.

In fact, other emperors could also have endured to this level if they had just toughed it out.

The problem is, they can't hold out for long before they're forced to return to the fifth floor.

Therefore, there is no need for that, since everyone is going to have to endure the lightning power within their own tolerance range for ninety-nine days.

"You can actually still hold on?"

Dugu Rou looked at the Yellow Spring Emperor with some surprise, realizing that she had indeed misjudged him before; she hadn't expected this guy to be so strong.

"I was originally a corpse that had become spiritualized and developed new intelligence. My previous life was a quasi-supreme being, so my physical body is much stronger than others. Moreover, I have been stained with the blood of the White Venerable, so I should be able to withstand another one or two more layers."

The Yellow Springs Emperor explains.

Next, they entered the seventh floor.

We're now approaching the core area of ​​Thunder Sea.

The color of the lightning also changed from red to dark red!

As soon as Chen Xuan entered, he felt a shiver run through his body, a slightly tingling sensation.

Beside her, Dugu Rou's expression turned somewhat pained.

Clearly, this level of lightning was causing her pain.

However, Chen Xuan soon heard two rapid heartbeats.

After the heartbeat stopped, Chen Xuan saw that the pained expression on Dugu Rou's face had disappeared, and she had become calm and composed again.

This is Angel Heart putting its power to work.

Chen Xuan was speechless for a moment. What was the difference between Dugu Rou's situation and cheating in a game?

Whenever you feel unwell, a couple of heartbeats and all your ailments will be cured.
