Caught in the hands of the Nine Emperor Princes, Ye Xingchen did not resist, but looked at the map to see where this Nine Emperor Princes were going to take him.

However, after looking at the map for a while, Ye Xingchen found that the direction in which the Nine Emperor Princes were taking him still belonged to the Yellow region.

"Could it be that the Nine Emperor Princes know about the other Demon Venerable Palaces?"

Ye Xingchen guessed in his heart.

This is very likely, after all, the Central Divine Kingdom does not know how many times it has explored the Chaos Secret Realm, and it must know a lot of Demon Venerable Palaces.

With the passage of time, Ye Xingchen's guess was confirmed.

Because in Ye Xingchen's psychic power induction, a black war fortress had been discovered, which was similar to the Demon Venerable Palace they had attacked before.

"Did you find out?"

The Nine Emperor Princes sensed the change in Ye Xingchen's face, and snorted coldly: "Later, give me all my strength to attack that Demon Venerable, I know that the mind attack can ignore the formation of the Demon Venerable Palace, as long as you severely damage the Demon Venerable once, I can take the opportunity to destroy the formation, and the rest will be left to me." ”

"I'm afraid I need to burn my psychic power to inflict heavy damage on the Demon Venerable. Ye Xingchen said in a deep voice.

The Nine Emperor Princes said lightly: "100,000 years, after the matter is completed, I will let you cultivate in the Time Tower for 100,000 years, which is enough for you to recover your spiritual power." ”

"No, it's too short, it will take at least 200,000 years. Ye Xingchen naturally wanted to increase his time and seek benefits for himself, after all, he needed time to improve his Chaos Overlord now.

"150,000 years, 150,000 years at most, don't play tricks on me, you kid. The Nine Emperors' eyes were sharp, staring at Ye Xingchen like a pinprick, and he said in a cold tone without question.

Ye Xingchen gritted his teeth and said, "Okay!"

In his heart, he was overjoyed, with these 150,000 years, he could at least raise the Chaos Overlord to %45, and then he would be comparable to a demi-saint.

With the strength of a demi-saint, not to mention being able to defeat the Nine Emperor Princes, but at least self-protection is enough.

Of course, Ye Xingchen wanted to hide his strength for the time being, and he couldn't let the Nine Emperor Princes find out, and he also wanted to spend more time cultivating in the Time Tower, after all, once he had a bad relationship with the Nine Emperor Princes, then he didn't want to enter the Time Tower to cultivate again.

"Huh!"

After negotiating the conditions with the Nine Emperor Princes, the two of them had already come to the sky above the Black War Fortress, and when they looked down from above, they saw that the Black War Fortress was full of demons, and they also found Ye Xingchen and the Nine Emperor Princes, two strange invaders, who were surging towards them.

"Remember your mission, I'll take care of the rest!"

The Nine Emperor Princes snorted coldly, and then sacrificed a powerful royal soldier, which was also made of holy soldier materials, like a long flaming red whip, and swept away, and the demons surging in front of him all screamed and died.

Ye Xingchen's pupils shrank, his face was extremely solemn, and he found that among these slain demons, there were many Great Heavenly Kings, and there was even a strong man comparable to the level of a marshal.

However, under the sweep of the whip of the Nine Emperor Princes, even the Great Heavenly King at the level of the marshal had to die tragically, and it was not conceivable.

"The strength of the Nine Emperor Princes is very strong, infinitely close to the saints, much stronger than the average half-saint. Moreover, this king soldier of his is already the top king soldier, as long as he becomes holy, this king soldier will also evolve into a holy soldier. ”

Ye Xingchen watched carefully, probing the strength of the Nine Emperor Princes.

Because if he wants to get rid of the Nine Emperor Princes, sooner or later he will confront the Nine Emperor Princes, of course, he must understand his strength in advance in order to deal with it.

"Hurry up!"

Suddenly, a loud shout sounded in Ye Xingchen's ears.

Ye Xingchen stared at it and found that the Nine Emperor Princes had swept away the attacking demon army, and the remaining demons were so frightened that they hid in the black war fortress and did not dare to come out when they saw the terrifying power of the Nine Emperor Princes.

They are not idiots either, obviously seeing that the strength of the Nine Emperor Princes is too strong, they naturally will not come out to send them to death, and defend with the help of the formation of the Black War Fortress.

"Boom ......"

Ye Xingchen flew in front of him, and the huge spiritual power diffused out, and he immediately understood everything in the Demon Venerable Palace.

At the same time, the Demon Venerable who was sitting in the center of the formation was also seen by Ye Xingchen.

"It's going to burn the psychic power again!"

Ye Xingchen smiled bitterly, and then without hesitation, he burned his spiritual power, condensed a huge and incomparably huge heart sword, and fiercely killed the Demon Venerable hiding in the center of the formation.

The Demon Venerable who presided over the formation suddenly stood on end, and his eyes swept around sharply, he obviously sensed the danger coming, but unfortunately he didn't know what it was.

By the time he guessed that it was a psychic attack, it was too late.

"Poof!"

Demon Venerable's soul was torn apart by the Heart Sword, and he let out a miserable howl, spurting blood in a big mouth, and flew out upside down.

After burning his spiritual power, Ye Xingchen's state of mind almost reached the peak of the sixth level, under the impact of this huge spiritual power, even if he used the strange things of heaven and earth, he couldn't resist it, let alone the Demon Venerable who didn't have the strange things of heaven and earth.

Of course, as a half-saint, the Demon Venerable's state of mind has also reached the peak of the fifth level, so it is impossible for Ye Xingchen to kill the Demon Venerable with his heart sword in seconds.

"Whew!"

After Ye Xingchen severely injured the Demon Venerable, he continued to condense his heart sword to kill the Demon Venerable.

Burning psychic power would wear off quickly, and he had to save time in order to give the demon the most of his creation.

"Puff puff!"

Demon Venerable was attacked by the Heart Sword three times in a row, only to feel that his soul had been torn to pieces, and he was no longer capable of presiding over the formation.

"Good!"

The Nine Emperor Princes had always firmly locked on the Demon Venerable, and when he sensed the laxity of the Demon Venerable, he immediately burst out with all his strength and bombarded the formation in front of him fiercely.

"Click!"

The void shattered, and the formation cracked with it.

After all, without the formation presided over by the Demon Venerable, it would not be able to block the attack of a demi-saint at all, let alone a top demi-saint like the Nine Emperor Princes.

"Roar!"

As soon as the formation broke, the Demon Venerable also stabilized the injury of his soul, and he roared and rushed towards the Nine Emperor Princes, fighting fiercely with them, and the powerful aftermath of the battle shattered the surrounding voids.

Ye Xingchen had already been hiding far away, so he would not participate in a battle at this level, and with his current strength, he was not qualified to participate.

"Just observe the specific combat power of the Nine Emperor Princes!"

Ye Xingchen watched the battle carefully from a distance.

As the saying goes, knowing oneself and knowing the other side can not be defeated in a hundred battles, as long as you understand the Nine Emperor Princes, you can deal with him.

However, the more he watched the battle, the more Ye Xingchen found that the Nine Emperor Princes were terrifying, from beginning to end, the Nine Emperor Princes were suppressing the Demon Venerable, and the Demon Venerable didn't even have a chance to escape from the Nine Emperor Princes.

This is overwhelming strength.

"If it weren't for the Demon Venerable hiding in the formation, even if the Demon Venerable's soul was not injured, I'm afraid it would not be the opponent of the Nine Emperor Princes. ”

Ye Xingchen was secretly surprised.

The strength of the Nine Emperor Princes has definitely reached the peak among the Half-Saints, and with such a background, as soon as the Nine Emperors break through to the Holy Saints, they will be able to immediately reach the peak of the Little Saints.

But this is obviously not the goal of the Nine Emperor Princes, he wants to go one step further, and when the time comes, he will become a great sage.

A powerhouse of the Great Sage level, looking at the entire Chaos Continent, no matter where he is, he is a giant.

This is the capital that is truly based on the Chaos Continent.
