If Lu Feng didn't guess wrong, the few demon emperors in the depths of the Heavenly Thunder Mountain Range who had reached the True Martial Realm had not been killed by the True Martial Artists of the Killer Dynasty, so they must have received the Heavenly Killing Order.

The heavenly killing order is coated with highly poisonous, and after receiving the heavenly killing order, the toxin must enter the body, and there is no second possibility.

In the martial arts world, the poison of the Heavenly Killing Order is incurable, even if Lu Feng knows the formula of the antidote, but the martial arts world does not have the natural treasure to refine the antidote, only by relying on the pills given by the Killer Dynasty can the toxicity be curbed and survive in the world, the means of the Killer Dynasty, Lu Feng couldn't be clearer.

For something like this, as the master of the Lei Yuan Palace, as the controller of one party's forces, it was absolutely impossible to tell his subordinates, even Huo Jue, the ancestor of the Huo family, did not tell the elders of the Huo family about the poisoning, and even Huo Xiaolin, the head of the Huo family, and the law enforcement elders of the Huo family.

In the Tianlei Mountain Range, the Demon Emperor who received the Heavenly Killing Order was afraid that he would have to go to the Holy Martial Platform to gather, otherwise he would definitely die once he was poisoned.

And this demon emperor of Lei Yuan Hall didn't even mention half a word, which shows that this is an old fox.

In any case, as Lu Feng continued to penetrate deeper into the Heavenly Thunder Mountain Range, the sword spirit's sense of the Immortal Sword became stronger and stronger, indicating that the Immortal Sword had not been discovered by the people of the Killer Dynasty, which was the best news for Lu Feng.

"Young Master, why don't we go to Lei Yuan Hall first and think about it in the long run. ”

Xu Man asked tentatively, he also sensed the seriousness of the matter, but other than that, Xu Man couldn't think of any better way.

"No, go directly to the deepest part of the Heavenly Thunder Mountain Range and look for the Immortal Sword!" Lu Feng said.

At this time, I went to the Lei Yuan Palace, and I saw the hall master of the Lei Yuan Palace, and when I entered the depths of the Tianlei Mountain Range, I was afraid that it would attract the special attention of the hall master.

Lu Feng could conclude that the hall master of Lei Yuan Hall was a scheming and cunning old fox, and it would only be more troublesome when the time came.

"The Demon Emperor who was destroyed, where is the territory under his control?" Lu Feng asked.

Xu Man stared at him for a while, and guessed Lu Feng's thoughts, in the Tianlei Mountain Range, several demon emperors each occupied one side, if they wanted to pass by the territory of these demon emperors and break into the deepest part of the Tianlei Mountain Range, they would inevitably be intercepted, and one of the demon emperors was killed by the true martial artists of the Killer Dynasty, and the forces under them were also burned, which just provided a convenience for the three of them.

Immediately, Xu Man squatted down and drew a simple sketch on the ground with his fingers, marking the various forces in the Tianlei Mountain Range, which was clear at a glance.

"The place controlled by the slain Demon Emperor is here, adjacent to the territory of the Lei Yuan Palace. However, the other demon emperors are very interested in this area, but they are afraid of each other, and they have not yet started to fight. Xu Man said.

"Very good, let's go now!"

Lu Feng's eyes were shocked, flashing a gleam, now is the best time to break into the deepest part of the Tianlei Mountain Range, looking for the Immortal Sword, if the demon emperors of the Tianlei Mountain Range have carved up that area, Lu Feng wants to break through again, but he is afraid that there will be a lot of trouble.

The two of them swept at extreme speed, following the planned route, towards the deepest part of the Tianlei Mountain Range. Xu Man entered the Lei Yuan Hall and achieved the position of one of the four demon kings, all by his own ability, and there was no kindness in it, leaving the Lei Yuan Palace, Xu Man had nothing to be nostalgic for.

Galloping all the way, the two of them did not encounter any trouble, and soon they left the realm controlled by the Lei Yuan Hall and entered the territory controlled by the force that was destroyed by the True Martial Realm of the Killer Dynasty.

There are almost no fierce beasts that dare to stay in this area, thousands of miles away, and they can't even find a living creature, but they see a lot of blood stains and severed limbs, especially the base camp of the demon emperor, which is even more miserable, and I can't bear to look at it directly.

"Young Master, I have only been to the deepest part of the Heavenly Thunder Mountain Range once, and I am not very familiar with it, even the several demon emperors of the Heavenly Thunder Mountain Range are not willing to stay in that place for too long. Xu Man reminded that he was well aware of the danger in the deepest part of the Tianlei Mountain Range.

"It's fine. ”

Lu Feng said with a faint smile, the dangerous place that the creatures of the True Martial Realm cannot break into, Lu Feng may not be able to enter, this time, the Immortal Sword is bound to win.

After a few days of wild sweeping, the two finally saw the deepest part of the Tianlei Mountain Range, this place is full of strange rocks and dangerous peaks, thunderclouds in the sky dome cover the sky, extremely dim, only the flickering thunder can bring a ray of light to the heaven and earth, and the power of thunder in the air has increased several times compared with other places.

Rao broke into this place with the strength of Lu Feng, and he also felt his scalp tingle, not because of horror, but because the power of thunder came into contact with his body, bringing a strong sense of discomfort, and then Lu Feng had to use his true qi to resist the violent thunder power around him.

Rumble!

Suddenly, a deafening thunder exploded in the sky, as if it was bursting out above Lu Feng's head, and even when he saw it, a thick thunder six or seven zhang wide was slashed in the air, and the momentum was immense.

Lu Feng was able to avoid it, but he was still hit by the power of the violent thunder, and his body was numb for a while.

"It's scary!"

Lu Feng's heart was slightly shocked, and he sighed secretly, in the end, it is worthy of being an extremely dangerous place in the martial arts world that is second only to the Tongtian Divine Pillar, even if he is a strong man at the peak of the Heavenly Martial Realm, he will not be able to withstand the heavy blows of a few thunderbolts, and it will not be long before he is afraid that he will be bombarded into a blood mist.

When he was at the peak of the Earth Martial Realm, he was able to defeat a strong man like Huo Yuntian, who had already comprehended a trace of innate qi and subtlety, and now Lu Feng had the true power that could not be summed up simply in the five words of the peak of the Heavenly Martial Realm.

Lu Feng and Xu Man walked between the strange rocks and peaks, and their ears were always filled with rolling thunder, whether there would be a thick and amazing thunder, without warning, when the head was covered, that kind of moment, it can be described as a thousand shots, even Lu Feng had to raise the spirit of twelve points, in the nine meridians, the true qi was running wildly, and he could deal with emergencies at any time.

And for Xu Man, it is not a tempering, the demonic energy he cultivates is originally the thunder attribute, the thunder power of this place is powerful and pure, and it can quickly improve his cultivation, but it is not an easy thing to inhale such a violent thunder power into his body, the process is quite painful, there is no great perseverance, there is no courage to try.

Xu Man did not disappoint Lu Feng, knowing that this trip was a rare opportunity to cultivate, he gritted his teeth, and while following Lu Feng, he absorbed the power of thunder to cultivate, and his distorted hideous face was enough to show how much pain he had endured.

Any pain paid is rewarded, and the skyrocketing of true qi in Xu Man's body also made Xu Man extremely excited.

A moment later, in the space of the Burning Immortal Sword, there was a somewhat heavy figure of the sword spirit!

"That cliff! The Sword of Immortal Robbery is there!"
