In the realm of emptiness, Chu Dui's state was unprecedentedly good, and all of them were clearly perceived by him.

The attack trajectory, movement trajectory, power transportation route, and other aspects of the bronze-level criminals were all mastered by Chu Duan.

The moment the bronze-level scolder was in danger, his heart contracted and expanded in an instant, as if there was a huge sound of a drum roaring, and an incomparably violent force came out of the bronze-level sinner's heart in an instant, with the moment of contraction and expansion.

That violent force, like the volcanic magma that had been silent for thousands of years, had accumulated to the limit, rushing out in an instant, destroying and destroying it, along the energy channel in the body of the bronze-level criminal, surging towards its arm, and then in a special way, spinning, impacting, contracting, exploding, and mixing with the power of the body to become one, thus bursting out with more powerful power.

Chu Duan persecuted the bronze-level criminals again and again, plunging them into a crisis, forcing them to unleash their violent power to deepen their observations.

After a few times, Chu Duan finally determined that he had clearly seen the strength and strength integration skills of this bronze-level criminal, and as for learning it, it was not a matter of a short period of time.

"Your value has been realized. Chu Duan said softly, and immediately took out his sword, this time, not to force the other party, but to really kill the other party.

Under the sword, the bronze-level sinner could not dodge, let alone burst into a counterattack, and was directly pierced through the chest by Chu Duan's sword, and under the clever sword skills, the edge of the blade oscillated at a high frequency, making the sword even sharper, cutting the chest of the bronze-level sinner. Instantly singled out the heart.

From piercing the opponent's chest to digging out the heart, it did not cause the slightest damage to the heart, and the whole process was completed in less than a breath.

Under the tip of the sword, the heart fell into Chu Duan's hands, and the bronze-level criminals who lost their hearts lost their source of strength and life, and their strong bodies became soft in an instant. Fell to the ground and died.

Bronze hearts are about the same size as black iron hearts. It's just that the color is bronze, hot, and beating, showing a strong vitality. However, Chu Duan felt the violent power contained in the bronze heart in his hand. It doesn't seem to be as much as you think.

"It looks like it was consumed before. Chu Duan said secretly.

Just now, in order to observe this bronze-level criminal's strength and strength skills more accurately and clearly. Chu Duan forced it again and again, allowing it to stimulate the power of the heart and display the skill of combining qi and power. Because of this, part of the power in the heart of this bronze-level sinner was consumed.

In this way, the value of this bronze heart is naturally not as high as in its heyday, but this is not important, the important thing is that Chu Duan has learned the skill of using the power of the bronze-level criminals, and he has also observed the skill of combining qi and strength.

Of course, it's one thing to observe, it's another thing to understand, and it's another thing to learn and master it, and the difficulty is increasing.

The difference in the structure of the body, the difference in the nature of the strength, etc., all determined that even if Chu Duan understood, he could not learn it immediately, and he had to devote time and energy to research, simulate, try, and finally modify it to fit his body in order to succeed.

"I wonder what about the other bronze sinners?" a thought came to mind.

After all, different black iron-level criminals will have some differences in their power skills and combat abilities, so is the same for different bronze-level criminals?

In the realm of emptiness, Chu Duan quickly locked on a bronze-level sinner who had broken through the defense line and had not yet been surrounded by patrolling Iron Wing soldiers.

The color of the skin of this bronze-level sinner appeared slightly cloudy, indicating that its strength was not as good as the one that was killed by Chu Duan just now.

Calmly, the sword, is constantly persecuting the other party.

For danger, the sinners have a high perception, especially the more powerful the sinners, the more obvious the perception, and they have extraordinary fighting instincts, will instinctively avoid danger, and when they can't dodge, they will try their best to fight back, which is completely a way of fighting with injuries for life.

Under this tremendous pressure, this bronze-level sinner naturally showed his strength to the extreme, and was lightly observed by Chu Dui to use his strength, and then, the skill of combining qi and strength was also forced to be displayed.

Just one time, Chu Duan saw clearly and understood, did not give the other party a second chance to cast, finished with a sword, picked out the heart, and killed the other party.

Keep searching, persecute again, then take it out, get the heart.

Repeat this process again and again.

More and more criminals rushed into the camp, and people continued to join the battle, so that Chu Duan's appearance did not attract much attention.

After killing five bronze-level criminals in a row, Chu Duan mastered his strength use skills and the skills of combining qi and strength, he felt that it should be enough, after all, it was much the same, and if he combined it, he could study and modify it himself.

Although the state of the Empty Silence Realm is very good, except for the first time when it is comprehended, it will obviously consume the power of the Yuan Shen when it is used later.

It felt as if it was burning with the power of the primordial god as fuel in exchange for the state of the Empty Silence Realm, and when it was almost the same, Chu Duan stopped using the Empty Silence Realm.

The power of the Yuan Shen consumed more than forty percent and nearly fifty percent at once.

Without entering the realm of emptiness, Chu Duan still had amazing strength, lower than the strength of the peak of the seven-star saint level, and he was not his opponent at all.

After that, Chu Duan did not deliberately look for any level of sinners, as long as the sinners broke through the defense line and entered the camp, and they were relatively close to him, Chu Duan would use his sword to kill them, if it was a black iron level sinner, he only used the power of the Holy Body, and applied the power use skills learned from the bronze level sinners.

......

"Up, surround it. Zheng Qi led a team of soldiers to patrol the camp, looking for criminals who broke through the defense line and killed them.

Zheng Qi's level is the middle level of the seven-star saint level, but his strength has reached the ordinary seven-star saint level high level, which is very strong, and there are nine elite soldiers under his command, all of whom have the strength of the six-star saint level.

One seven-star saint-level, nine six-star saint-level, and ten people are good at joining forces, even powerful bronze-level criminals will die under their cooperation.

Led by Zheng Qi, one after another broke through the defense line, the criminals died under their swords, and their hearts were gouged out.

"Get out!" Zheng Qi slashed out with a sword, directly forcing a sword saint to retreat, that sword saint did not belong to the Iron Wing Army, but a person who came from outside to enter the camp.

Facing the fierce and murderous Zheng Qi, the sword saint's face suddenly changed, and he hurriedly avoided it and quickly retreated.

As we all know, in the Iron Wing Battalion, it is best not to have any conflict with the Iron Wing Army, once there is a conflict, no matter who is right and who is wrong, the Iron Wing Army is not clear, but he will definitely be unlucky, because this is the base camp of the Iron Wing Army, looking for trouble here, isn't it looking for death.

Even if it is an eight-star and nine-star Sword Master, here, he will retreat a little.

After repelling the other party, a smug look flashed on Zheng Qi's face, but he did not pursue, because his purpose was to kill the criminals.

It just so happened that Zheng Qi's direction was coming from Chu Duan's side.

It didn't take long for Zheng Qi to see Chu Dui, and Chu Dui was fighting against a powerful black iron-level sinner, this sinner's skin was gray and black, and he didn't seem to have any impurities, and his strength was comparable to that of an ordinary four-star saint-level peak cultivator.

Chu Duan fought with it, and he didn't use all his strength, but he was just trying new power use techniques, striving to be familiar with them, mastering them thoroughly, and he was also honing the concussion skills of sword power.

This scene, in Zheng Qi's opinion, is Chu Duan's strength.

"It's good, it's a genius, but so what. Zheng Qi said secretly, a sneer flashed on his face, and immediately, he gave a look at a warrior under his opponent, and then looked at Chu Duan.

"Understood. "As a soldier under Zheng Qi, following Zheng Qi for many years, I understand Zheng Qi's character, and this warrior immediately understands what Zheng Qi means.

He looked at Chu Duan and found that it was only a four-star saint-level beginner, although the strength of the table was not bad, but it was countless different from the six-star saint-level.

"Poor fellow, you can only be considered unlucky. The warrior sneered secretly.

If it was in peacetime, Zheng Qi would not dare to do this, after all, when other people entered the Iron Wing Army, a large part of it was with the help of the Iron Wing Battalion to rest, which was equivalent to paying them the hearts of the criminals and getting safety here, and the Iron Wing Army must ensure their safety, so they must not be touched.

But at this time, it was the time when the criminals attacked the camp, it was very chaotic, everyone cared about fighting, caring about saving their lives, and there was no time to care about anything else, and it was the best time to kill.

Even if it is seen, after the fact, the responsibility can be put on the criminals, there is no way to pursue it, and even if it is pursued, it will be closed in the end, because after the criminals attack, the camp needs to be reorganized.

Chu Duan, who was in the middle of the battle, naturally felt the approach of the other party and the malice carried by the other party, which was a kind of murderous intent.

Naturally, Chu Duan also caught a glimpse of Zheng Qi in the distance.

Suddenly, Chu Duan understood Zheng Qi's plan, but he didn't say anything, and he didn't immediately fight back.

The six-star saint-level warrior under Zheng Qi quickly approached Chu Duan, the sword was raised, and the murderous aura was permeated, and the magma-like sword qi flowed on the sword body, exuding an astonishing high temperature.

Then, the sword raised by this warrior slashed out, and it seemed that it was a sword that slashed at the black iron-level criminal, but Chu Duan felt that he was locked, locked by a scorching killing machine.

The real purpose of this sword is not the black iron level criminal, it is just a cover-up, and the target is himself.

A touch of coldness flashed in Chu Duan's eyes, since he was a killer to himself, he had to bear the corresponding price...... (To be continued......)
