A guilty conscience? Not really.

But that was indeed Ye Feng's first time killing someone, as an ordinary person who had transmigrated from modern times.

Killing so many people and then burning the bodies to cover it up—this is something no ordinary person could do.

I was able to endure the discomfort at the time entirely by sheer willpower.

Looking back now, I realize that I was definitely not in the right state of mind.

However, after experiencing so much, Ye Feng has grown a lot.

At least, I won't feel uncomfortable about killing someone anymore.

At the same time, the fact that he was undergoing foundational cultivation while suffering from qi deviation actually made his heart more resolute.

If he was somewhat worried about the demonic tribulation of the Golden Core stage before,

Now, he has nothing to fear!

"That's about enough! I'm going out to undergo a tribulation. Wait for me a moment, I'll be back to continue!"

Ye Feng, enveloped in a hazy white light, floated up into the air.

The magical robe automatically donned onto his body.

With his longsword in hand, the unruly Ye Feng reverted to his image as a refined young gentleman.

After giving Xiao Xuan a reassuring look, Ye Feng's figure suddenly flew out of the cave.

0-100 km/h acceleration in 0.01 seconds!

Located in the subtropics, the island experiences high temperatures and sunshine year-round.

But at this moment, the sky above the island was already shrouded in dark clouds, covering an area of ​​nearly ten kilometers in radius.

Flickering arcs of electricity darted through the dark clouds like white snakes.

Simply hovering in the sky gives one an extremely oppressive feeling.

Countless schools of fish and birds around the island fled the area.

Among them are many spirit beasts comparable to those at the Qi Refining and Foundation Establishment stages.

Ye Feng sensed the aura of lightning briefly and felt a little relieved.

This strength is acceptable; it would be even better if it could be broken up beforehand.

However, Ye Feng gave up after a short while.

The lightning seemed right in front of them, but in reality, they were incredibly far away, or perhaps they weren't even in this space at all.

He flew upwards for dozens of kilometers, but the thunderclouds remained firmly overhead, so he had no choice but to give up and return to the island.

In case anything goes wrong, Qinghe will help clean it up...

Now all the intelligent animals on the island have fled, except for Xiao Xuan, who is in the cave.

Although the lightning tribulation may occasionally affect others, its primary target is the person undergoing the tribulation.

Ye Feng had already set up an array in Xiao Xuan's cave, so as long as he didn't run inside, there would be no problem.

The magical power within his body was still flowing continuously into his dantian.

An ordinary person has only about a thousand acupoints per point, and even in advanced cultivation techniques, the maximum is only two thousand.

But in Ye Feng's case, each acupoint costs five thousand.

The golden core has already expanded to nearly three centimeters and is still growing.

I've heard that a human's Golden Core is at most ten centimeters long. Once it reaches ten centimeters, the next step is to break through the Core and become an Infant.

Am I... about to break through to the fifth level of the Golden Core stage directly?

Finally, a five-centimeter-sized golden core formed inside Ye Feng's body.

The golden core was white, emitting a hazy white light within Ye Feng's body, with two small lines on it.

Second-grade Golden Elixir!

The cultivation technique records obtained in the Azure Cloud Secret Realm

Golden Elixir is divided into nine grades, from one to nine. The fewer the patterns on the elixir, the higher its grade.

A higher Golden Core grade means more and stronger magical power, which naturally leads to more opportunities to advance to the Nascent Soul stage.

Ye Feng hadn't expected that he could directly form a second-grade Golden Core.

The grade of a Golden Core is generally related to combat power, but most importantly, it's related to the cultivation technique. The more powerful the cultivation technique, the stronger the Golden Core formed.

This is also the difference between the upper and middle sects, and between the middle sects and independent cultivators.

Ye Feng originally thought that he was at most around the fifth rank.

After all, his original cultivation technique was still the Azure Cloud Technique. Although it had been improved with the Rank 1 technique, it was at most half as strong as others' techniques, and he would be lucky to reach the fifth rank.

Keep in mind that the Golden Core hasn't been tempered by the lightning tribulation yet!

To be precise, it's still a fake pill!

After being tempered by lightning, the golden core will naturally become stronger, and the patterns on the golden core will also disappear under the tempering, thus improving the grade of the golden core.

With just two lines, isn't a Grade One Golden Elixir a piece of cake?

But... is it possible to have absolutely no lines?

In theory, progressing from the first to the ninth level of the Golden Core realm involves more than just an increase in the size of the Golden Core itself.

Another point, which is also part of the process of repairing the golden core patterns,

Once the Golden Core is completely free of cracks, it's basically time to prepare for Nascent Soul formation.

If one's golden core truly has no cracks at all, wouldn't that be equivalent to being guaranteed admission to Peking University?

Ye Feng gave a self-deprecating smile.

This is basically impossible, because the energy within the Spirit Liquid Pill converges like a chemical reaction.

A first-class life is easy to pass, but a life without flaws is difficult to cross!

Of course, for ordinary people, achieving the highest rank is impossible.

It's like a pile of gunpowder with only one vent; the pressure the golden core has to withstand is no less than that of a bullet being fired.

The flawless golden elixir is essentially like confining the explosively reacting gunpowder within the elixir itself...

There's no use thinking about it too much. The tribulation has already begun. We'll find out what rank it will be after we see!

Ye Feng sat cross-legged atop the small island, surrounded by tens of thousands of high-grade spirit stones scattered about.

There's still the mana hurdle to overcome. If you don't have enough Golden Fruits, you can always use these tens of thousands of spirit stones as a safety net.

He arranged these spirit stones using array techniques. Once activated, they would instantly converge on him, providing the most crucial magical power!

"Click..."

The sky suddenly flashed, and a bolt of lightning, like a white dragon, snaked downwards, instantly reaching Ye Feng's head.

"Buzz!"

Suddenly, Ye Feng, who was sitting upright, took off from the ground and rose to a height of three meters.

Lightning surged into Ye Feng's head, reaching straight to his dantian.

The body bears only a very small portion of it, while the golden core in the dantian bears the majority!

But even this tiny portion that the body endures is a painful experience for many people.

With the magical power withdrawn from the dantian, one can only rely on the physical body to withstand it!

However, these lightning bolts are also magical tools for tempering the body. After undergoing tribulation, the body will generally be upgraded by one or two levels.

Moreover, if you feel you can't handle it, you can channel all the lightning into your golden core.

But for Ye Feng, these lightning bolts felt like a massage, incredibly soothing.

With a Foundation Establishment level 10 body refinement cultivation, enduring all the preceding lightning strikes would be a piece of cake.

However, it still cannot be fully absorbed, otherwise the golden core cannot be refined...

Ye Feng let nature take its course; whatever amount of lightning remained, his body absorbed.

Inhale neither too much nor too little.

The instant the lightning struck the golden core, a brilliant light emanated from its surface, and the five-centimeter-long core shrank slightly.

At the same time, the golden core rose more than ten centimeters upwards, facing the direction of the lightning tribulation.

The Golden Core Tribulation consists of thirty-nine stages.

Three times nine equals twenty-seven!

The first nine stages will extract the golden core from the body, while the middle nine stages will refine the golden core.

The next nine challenges are the real test!

Xiao Xuan dared not go out and could only wait quietly in the cave.

Hearing the thunder and lightning outside, I felt incredibly anxious.

But now, she could only wait quietly, lest Ye Feng be distracted...

Meanwhile, a hundred miles away, two figures stood in mid-air, watching this scene from afar.

"To actually undergo the Golden Core Tribulation on our turf without even a warning, it seems this person doesn't take us, the Black and White Duo, seriously."

"Hehehe, since we don't know his origins, we'll just kill him and take his core while he's weakened from his tribulation. He'll learn the rules in his next life!"

"Ah? Yeah, hahaha..."

The two looked at the thunderclouds in the distance and burst into unrestrained laughter...
