"Boom!"

With a loud bang, the breath on Chu Feng's body and Cheng Yu's body both exploded at the same time, Chu Feng's body was on the ground, but it was extremely close to the breath of the Heavenly Martial Realm, while the breath on Cheng Yu's body was the peak of the Heavenly Martial Realm!

The reason why the Heavenly Martial Realm is stronger than the Earth Martial Realm is because the martial artists who have advanced to the Heavenly Martial Realm can take off in the air, and their physical fitness has been greatly improved.

Of course, more importantly, all the powerhouses who advance to the Heavenly Martial Realm have the opportunity to comprehend their own martial strength, so that their combat effectiveness can be greatly improved.

Martial power is an extremely mysterious and obscure existence, at least Chu Feng has seen most of the Heavenly Martial Realms that he has not comprehended. Even the tutors of the Xuanling Academy are rarely able to comprehend such a thing as martial arts.

For example, a martial artist who has comprehended a certain kind of bloody killing intent, then when he is fighting, he can directly release this kind of martial power and wrap it around him, thus affecting the enemy. Those who are not strong may even be directly frightened by this killing intent, and thus lose the courage to fight.

For another example, a Heavenly Martial Realm powerhouse who has comprehended a special icy cold martial force can release this martial power. Although the martial power will not be like the Yuan Force and the martial arts, it will have a more obvious impact on the existence of the surrounding area. For example, the Ice Martial Force, which will make the enemy feel some kind of weird chill, will be affected by discomfort between shots, but it is difficult to freeze the things around it, and the same is true for the Flame Martial Force, which will not burn the surrounding existence, but it can make the opponent feel stuffy and irritable.

Moreover, the more powerful and well-understood the martial artist, the stronger the martial power of comprehension. More importantly, the attributes of Yuan Li also determine the martial power of comprehension. For example, it is basically impossible for a martial artist with fire attribute yuan power to comprehend the ice and cold martial power.

Having said so much, it was because of this Cheng Yu that he had actually comprehended the martial arts! Moreover, it was an extremely strange martial force, which Chu Feng had read in a certain martial arts book.

This kind of martial power is called [Night Shadow]

When Cheng Yu unleashed this kind of force, a darkness would appear at random at any time, as if night was falling, blocking Chu Feng's sight, and even all his perception abilities!

Moreover, the martial potential can increase with the improvement of strength! In other words, the current Cheng Yu can use this martial power to influence Chu Feng, plus Chu Feng's realm itself is lower than him, so it can be completely crushed!

This may be why Cheng Yu was able to defeat Xia Guming and them, and even kill the young master of the Heavenly Night Sect who had the strength of the Seven Heavens of the Heavenly Martial Realm!

Martial power, but it is extremely difficult to comprehend!

Basically, most of the martial artists who have just stepped into the Heavenly Martial Realm can't comprehend it!And now, this Cheng Yu is only the peak of the Heavenly Martial Realm's Triple Heaven, but he has already comprehended the [Night Shadow] martial power, how can he fight this?

"Whoosh!"

At this time, the battle had already begun, and Cheng Yu's figure rushed towards Chu Feng at extreme speed. Obviously, his speed was not very fast, but strange black patches appeared in front of Chu Feng's eyes from time to time, covering his vision, and sometimes even his spiritual perception.

As a result, it was difficult for Chu Feng to attack Cheng Yu at all!

Obviously, Cheng Yu was inferior to him in speed and strength, but his realm was high, but with his martial strength, Chu Feng still fell into disadvantage in the battle.

Fortunately, Cheng Yu's strength is not very strong now, and this [Night Shadow] force can only be used every few breaths, otherwise Chu Feng won't even have a chance to fight back!

"Slash!"

Chu Feng let out a low snort, raised the Phantom Giant Blade and slashed towards Cheng Yu's figure in front of him.

However, at this moment, a black shadow suddenly flashed in front of Chu Feng's eyes, and Chu Feng lost Cheng Yu's goal.

"Boom!"

With a loud bang, the Earth Phantom Giant Blade in Chu Feng's hand smashed directly to the ground with extremely terrifying power, smashing the ground into a deep pit. However, in the deep pit, there was no figure of Cheng Yu.

At this moment, Chu Feng felt a chill behind him approaching at a rapid pace, so he turned around and saw Cheng Yu behind him looking at him with a sneer.

In this regard, Chu Feng naturally counterattacked quickly. However, before he could make a move, he felt a pain in his abdomen, and then the whole person flew upside down.

"Damn, it's martial arts again!"

Chu Feng scolded angrily.

It is extremely difficult to comprehend martial power, but once comprehended, it is a great help in battle! Of course, martial power is not invincible. As the realm improves, the role of martial power will become smaller and smaller.

For example, when it comes to the Spirit Emperor, the battle between two Spirit Emperor Realm powerhouses, the role of martial power will become smaller, and it can be ignored when it reaches the Yuanzun Realm.

But now, Chu Feng faced Cheng Yu on the ground, but it made him feel extremely tricky. Obviously, the other party was just an ordinary Heavenly Martial Realm, but with the martial power, Chu Feng would not be able to attack him so easily!

"Boom!"

After Chu Feng's figure flew out upside down, he twisted extremely quickly, using his strength to stabilize his figure, and the ground was kicked out of a deep pit by him.

At this time, Cheng Yu had already stepped forward and directly punched Chu Feng. Seeing this, Chu Feng's pupils shrank and he raised his hand to resist.

"Bang, bang, boom!"

The muffled sound continued, and Cheng Yu blasted countless punches towards Chu Feng at a storm-like speed, and Chu Feng also resisted them all. But because of the black shadows that appeared in front of him from time to time, Chu Feng couldn't deal with Cheng Yu's attacks at all.

In the course of the battle, Chu Feng received several punches from him, and he was not lightly injured.

"Boom"

With a muffled sound, Chu Feng's figure was knocked out again.

But this time, Chu Feng was really angry.

"Boom!Boom~"

Suddenly, the aura on Chu Feng's body became extremely powerful, the vast star yuan power continued to spread, and white smoke rose from the surface of his body.

Immediately after, a strange flame appeared in his eyes, and a rich flame power and the Xingchen Yuan Force enveloped him all over his body.

At this moment, Chu Feng could already control the power of the Earth and Heavenly Fire in his body freely, even if the Red Lotus Burning Sky Fire did not appear, Chu Feng could also use the power of the Heavenly Fire.

When Chu Feng had a terrifying power rising to the ground, Cheng Yu's complexion finally changed, and a look of jealousy rose.

"Bang!"

When the battle resumed, Chu Feng's figure rushed out at great speed, fighting with Cheng Yu's figure. This time, it was Cheng Yu who fell into the disadvantage, because in the battle with Chu Feng, terrifying flames would appear on Chu Feng's body from time to time, making him unable to start.

Even if he endured the pain of attacking Chu Feng, the power of earth, heaven and fire on Chu Feng's body would make him pay a terrible price!

Cheng Yu was finally extremely angry and a little flustered.
