The latest free chapters of the book can be found here.

You must know that those super sects, overlord dynasties, peerless powerhouses of the hidden family, and one giant powerhouse, are all extremely powerful figures in mental power cultivation and physical body, only a strong physical body can withstand a strong mental power cultivation, otherwise, the strength of the physical body is not enough, and first of all, they will be oppressed into a pool of blood and mud by their own mental power cultivation and heaven and earth aura.

The pure Thunder Source Aura can be condensed into the Thunder Source Pill, which is a unique cultivation item in the Thunder Source Battlefield, just like the Yun Ling Stone, but the Lei Yuan Dan is much stronger than the ordinary second- and third-level Yun Spirit Stones, and only the rarer fourth-level and fifth-level Yun Spirit Stones can be comparable to the effect of the Lei Yuan Pill.

Therefore, Lei Yuan Dan is a unique circulating currency and cultivation item in this Thunder Source Battle Domain, which can be used for cultivation to improve strength, and can also be used to exchange and trade with others, which is widely used and has a great effect.

Ye Yun and Yang Dong continued to march rapidly among the mountain peaks, crossing patches of jungles.

In this thunder source battle domain, the day is not the most dangerous, the most dangerous is the night, when the night covers the boundless earth, countless hidden crises will be ready to move, including monsters, dark necromancers and demons, as well as the mindfulness itself, where there are people, there is fighting, there is danger.

The map in Ye Yun's hand showed that there was a dent of the Nian in this area, which was a deserted ancient city, which could barely be used to survive dangerous nights, so before dark, Ye Yun and Yang Dong had to rush to that ancient city, and I believe that many young Nians who participated in the Hundred Dynasties War did the same

Hurrying all the way, Ye Yun and Yang Dong finally arrived at the ancient city before it was dark.

In the distance, you can see that there is a mottled ancient city located on the endless wilderness plain, and the black stone on the city wall has traces of the vicissitudes of time, recording the wind and rain it has experienced, exuding a trace of ancient and vast heavy atmosphere.

Above the tall dark gray gate, there is a plaque that reads "Black Rock City".

Ye Yun and the others couldn't help but be overjoyed, and quickened their pace.

"Hmmm, mph. ”

At a distance of more than twenty meters from the Black Rock Ancient City, the two of them slowed down their march, because there seemed to be a few guarding minds standing on both sides of the gate of the Black Rock City, and Ye Yun and the two of them acted in such a hurry, it was easy for people to misunderstand.

Seeing Ye Yun and the two coming, the Nian who guarded the city gate of the Black Stone Ancient City also stepped forward and looked at the two of them cautiously, these Nian Nian guarding the city gate looked like they were only seventeen or eighteen years old, and they seemed to be young Nian Nian of other dynasties.

"Which dynasty are you from? A young man at the head asked, the mental aura on his body was in the early stage of a round of recitation.

"Ladies and gentlemen, we are the minds of the Hanyan Dynasty, and we want to spend a night in this ancient city of Black Stone, hoping to make it convenient. Ye Yun said with a smile.

"Really, bring your telekinesis out and take a look. The boy said, his face cautious, but he didn't seem to have any malice.

Seeing this, Ye Yun didn't think much about it, his slender and white palm stretched out, and a trace of cold mental power surged in his palm, and Yang Dong next to him also urged his mental power out.

Seeing the mental power of the two of them, the cautious look on the young man's face finally dissipated a little, and said, "Don't get me wrong, I also did this to prevent some spirit beasts that turned into human forms from sneaking into the ancient city of Black Stone, and now you can go in." ”

Hearing this young man's explanation, Ye Yun and Yang Dong immediately understood, although this Thunder Source Battle Domain is a cultivation treasure with a strong spiritual aura of heaven and earth, but there are also hidden dangers everywhere, here, there will definitely be some spirit beasts that are strong enough to turn into human form, if they sneak into the stronghold of this Black Stone Ancient City, I am afraid that everyone in the city will suffer.

Then, the two of them walked towards the ancient city of Black Stone.

Entering the ancient city, everywhere you look, there is a scene of ruined vicissitudes, collapsed black stone houses, broken stone pillars, etc., many of them looked at Ye Yun and the others, but after seeing the same, they retracted their gaze and continued their cultivation.

In this ancient city of black stone, each mindful found a place for themselves, cultivating quietly, absorbing the thunder source aura between heaven and earth.

The cultivation atmosphere here is not bad, Ye Yun and Yang Dong saw this, they also found an open place, sat down cross-legged, and began to cultivate.

Between heaven and earth, Lei Yuan's aura is everywhere, although it is very thin, but it can strengthen and refine the body of the mind, the meridians of Ye Yun's limbs and hundreds of bones are all running, and in the lower abdomen, the golden life chart constantly exudes a faint light, and a stream of mental power surges out, running in Ye Yun's meridians for one week after another.

The thunder source aura between the surrounding heaven and earth converged towards his body in a trace, and was absorbed into the meridians, refining little by little, and then, a thin trace of light blue energy emerged.

When Ye Yun and Yang Dong first arrived, the first task was to refine and condense the Lei Yuan Dan, the Lei Yuan Pill was a product condensed by the Nian after refining, with the Lei Yuan Dan, Ye Yun and Yang Dong's actions in this Lei Yuan War Domain were also more convenient.

Immediately, Ye Yun silently urged the power of devouring, speeding up the speed of absorbing the thunder source aura between heaven and earth.

After staying for more than thirty minutes, a light blue round pill appeared in Ye Yun's palm, exuding a trace of thunder source power aura, this is the thunder source pill.

Ye Yun has the power to devour, so it takes thirty minutes to be able to condense a Thunder Source Pill, and if it rests on those ordinary thoughts, I am afraid it will take more than forty minutes.

In this way, Ye Yun tirelessly absorbed and refined the thunder source aura between the surrounding heaven and earth, condensing the thunder source pill.

Time passed little by little, and the sky was completely darkened, and a trace of black night shrouded the entire Blackstone Ancient City.

During this period, Yang Dong beside Ye Yun was called out to replace the previous Nian who guarded the ancient city of Black Stone, in this ancient city of black stone, everyone was only temporarily resting, so everyone needed to guard the city gate for a period of time, and it was estimated that it would be Ye Yun's turn soon.

"Rumble~"

Ye Yun was cultivating, and suddenly felt that the ground began to shake, and even if he opened his eyes, many cultivators around him also opened their eyes and looked around vigilantly.

Faintly, there seemed to be a chaotic sound of stomping on the ground in the distance, and it seemed that something was coming towards the ancient city of Black Stone, and the speed was very fast.

"Oh no, there's a tide of beasts. ”

Suddenly, a young girl guarding the city gate ran back and shouted anxiously to the crowd.

"What. ”

"Beast tide. ”

Suddenly, many reciters lost their voices, obviously, a little flustered about this kind of thing.

"Don't be afraid, as long as we work together to guard the city gate, the monsters shouldn't attack in. ”

At this time, a deep voice sounded, Ye Yun looked, and saw a slender young man in a green shirt shouting towards everyone, quite a leader.

So, the panicked crowd immediately found the backbone.

"We listen to you, what do you say. ”

"Yes, you say. ”

"Okay, now some people go to the city gate to resist the beast tide with the guarding minds, and some people climb the city wall and attack the beast tide. ”

Ye Yun couldn't help but nod when he heard the words of the young man in green shirts, his method was still more feasible.

Immediately, Ye Yun walked quickly towards the city gate, because Yang Dong was still guarding the city gate.

Some of the reciters in the ancient city of Black Rock rushed to the city gate like him, and some of them climbed the city wall.

Arriving at the city gate, Ye Yun saw Yang Dong.

"Ye Yun, you're here.

Ye Yun nodded, and immediately looked into the distance, only to see that on the horizon in the distance, a group of black-pressed demon beasts rushed towards the Black Stone Ancient City, with a demonic aura that soared into the sky.

At this time, there were about thirty or forty ninters at the city gate, and most of them were in the realm of the early stage of the first round of ninths, either with their bare hands, or with their own ninths, their minds were surging, and they were ready for battle.

When the group of black-pressed demon beasts approached the range of more than a hundred meters of the Blackstone Ancient City, Ye Yun also saw their scale clearly, there were about two hundred, all of them were at the level that had just touched the threshold of the handsome level.

Most people still had a hint of surprise on their faces, after all, it was the first time they had seen a beast tide of this scale.

"Roar. ”

A high-pitched beast roar sounded, and those demon beasts became even more excited, rushing madly towards the ancient city of Black Stone, with a strong demonic aura, I saw that it was a group of demon beasts more than two meters long, red all over the body, with hideous faces, and a pair of red demon eyes on the head were extremely conspicuous, Ye Yun recognized that this was a unique demon beast in the Thunder Source Battle Domain, a red-eyed beast, fierce by nature, usually living in groups, and it was also a group when hunting.

In a few breaths, those red-eyed beasts rushed across a distance of more than a hundred meters and arrived in front of everyone, devouring them with great ferocity.

"Hmmm. ”

I saw a red-eyed beast with a red claw, with a demonic aura, tearing towards Ye Yun fiercely.

Ye Yun's face turned cold, the thundering spear appeared in his hand, and the icy cold mental power gushed out, swallowing out dozens of centimeters of spear qi and swept out.

Sweep through thousands of armies.

"Bang. ”

The thundering spear landed heavily on the red-eyed beast's body, sending it flying several meters, but soon, the red-eyed beast got up and tore at Ye Yun again.

A trace of surprise flashed in Ye Yun's eyes, he didn't expect that the body defense of these red-eyed beasts was so strong, and under his blow, he couldn't do much damage to this red-eyed beast.

Immediately, Ye Yun figured it out, the Thunder Source Battle Domain contained a rich Thunder Source aura, and after the demon beasts absorbed it, they could also cultivate, and the power of the Thunder Source also had a strengthening and refining effect on the body of the demon beasts, so these red-eyed beasts were also much stronger than ordinary demon beasts.

Without knowing about these red-eyed beasts, some of the minders suffered a lot of losses, and scars appeared on their bodies. Cat flutter Chinese
