Swish, swish, swish...

In the hall at the top of the Chengta Mountain, colorful and strange sword lights kept flashing, just like the polar lights constantly appearing, which was dazzling!

Since you cannot see through the attack effectiveness of the flame dragon slaying and the five elements true fire fusion by relying on your eyes, Du Long can only use the swords to understand the mystery!

However, after slashing the swords for a long time, he didn't understand the reason. He didn't even feel how amazing the power of the two burst out after they merged!

call!

Du Long, who had to stop, exhaled a long breath of turbid air and muttered to himself in confusion: "I thought the power of the Five Elements True Fire and the Flame Dragon Slaying Slash would be after the fusion of the Five Elements True Fire and the Flame Dragon Slaying Slash. After practicing for a long time, I couldn't tell how powerful it was?! In this way... I could even cut through the dark light domain energy cover with one knife?!"

"Isn't it because of the power...but because after the combination of the two...the flame dragon slaying slash becomes sharper?!"

Suddenly, Du Long thought of this possibility and couldn't help but lit his eyes: "In this way, you can test the sharpness of the Five Elements True Fire and the Flame Dragon Slaying Slash, so that you can figure out why you can break the dark light domain energy cover so easily!"

"Haha!" Du Long laughed excitedly as if he found the direction again, "Senior Chiyou! Can you help me simulate an energy shield similar to the dark light domain? I can test the attack effectiveness of the Five Elements Flame Dragon Slaying Slash?!"

"Of course it's no problem!"

Chi You didn't show up, and responded directly, and immediately a black energy ball appeared in front of Du Long: "Don't worry and slash boldly! I just watched your battle, so I naturally knew the protection of the Dark Light Domain Energy Cover. At this moment, the energy structure inside the black energy cover in front of you is almost the same as the Dark Light Domain!"

"Senior Xie Chiyou!" Du Long thanked him with gratitude, and then waved his sword without hesitation and slashed at the dark black energy ball with all his might. Then he heard a muffled sound from the ground. The energy ball shrank inward under the slash of the Dragon Slaying Slash, and then there was no sign of being slashed and rebounded directly to its original state!

The Flame Dragon Slaying Slash was bounced back suddenly. Du Long took several steps back in a slight embarrassment before stopping his body. He immediately murmured with depression: "What's going on?! I didn't even slash it out with this knife?"

"Haha!" Chi You's chuckle immediately sounded in the hall: "How can you easily break this dark energy ball without using the magic of heaven and earth, and without using the Fire Cloud Cauldron to bless the arm strength?!"

Well!

Du Long's face turned slightly red, and then he hurriedly used his magical powers one after another. His whole person immediately entered the state of Dharma heaven and earth, but he did not use the three-headed and six-arm and the ultimate transformation magical power!

Under the second level of Dharma Heaven and Earth, Du Long held a knife in his right hand and held the Fire Cloud Cauldron with his left hand. A terrifying fire energy was blessed into his right arm, and the five elements true fire was blessed to the flame dragon slaying!

After making these preparations, Du Long finally let out a low voice and slashed a terrifying knife at the dark energy ball with all his strength!

Scream!

Finally, the Flame Dragon Slaying Slash successfully cut open the dark energy ball light cover, like an extremely sharp blade passing through a ball, instantly slashing it into a sky full of dark energy and splashing everywhere!

Looking at the power displayed by his sword with satisfaction, Du Long nodded and said, "As expected, it was like the one that cut it through. It seems that only the full-strength attack of the late-stage combat power of the Heavenly Emperor Realm, plus the super artifact of the Fiery Dragon Slaying Slash blessed by the Five Elements True Fire, can we break through the wall protection of this dark energy light ball!"

"Haha! Very good! But..." Chi You's chuckle sounded again in the air: "I'll give you a suggestion. The one I tested before was to attack the dark energy light ball. Now you can test your energy ball in the light system with all your strength to see if you can cut it through with one knife!"

Du Long's eyes lit up suddenly, and he instantly understood the meaning of Chi You's words, and immediately said excitedly: "Okay! Please let me get a light energy ball to me and test it!"

Um!

After Chi You let out a light whistle, a ball of energy flashing with blazing light appeared in front of Du Long out of thin air. Judging from the energy fluctuations it emitted, it seemed to be almost the same as the previous ball of dark energy!

His eyes locked on the crystal clear energy ball in front of him. Du Long did not hesitate too much and slashed out with all his strength. The sword light instantly slashed the light energy ball in front of him!

Pang!

The light energy ball suddenly sank inward, and then rebounded back instantly. This scene was exactly the same as the previous failure of the attack. Du Long was shocked several steps by the terrifying force before he stopped!

Well!

Looking at the light energy ball in front of him speechlessly, Du Long shook his head helplessly after a moment of surprise and sighed: "Oh! Senior Chiyou! Are you sure that this light energy ball is of the same grade as the dark energy ball?!"

"There is definitely not much difference!" Chi You did not blame Du Long for not trusting him, and replied to him in a straightforward and neat way.

"Okay!" Du Long also knew that he was questioning the wrong way, so he immediately changed the topic and said, "I wonder why my senior suddenly suggested that I attack the light energy ball with the same protection?!"

Although he had some guesses in his heart, Du Long still asked about this question. After all, his guess may not be correct. This still requires the experienced Demon Lord Chiyou to prove it before he can rest assured!

"Haha!" Chi You chuckled and replied: "The reason is very simple, that is, the principle of attribute mutual generation and mutual restraint. The main reason why your Flame Dragon Slaying Slash can cut through the energy protection wall of the dark light domain is not that the attack power exceeds the protection limit of the energy wall, but because the Flame Dragon Slaying Slash under the blessing of the Five Elements True Fire has a certain restraining function for the dark energy, which can help you successfully cut through the powerful dark wall of the energy!"

"So that's it!" Du Long said with a sudden expression on his face: "In this way, since the Five Elements Flame Dragon Slaying Slash does not have the effect of restraining the energy of light, it is impossible to cut it out with one knife when the energy cannot exceed the limit!"

"That's exactly!"

Du Long finally figured out the data behind his sword. What made him happy and worried was that this sword was only effective for the dark light domain. If the opponent had a similar trapping array of light, he might not be able to get out of trouble so easily!

call!

He exhaled a long breath of turbid air and fused the Five Elements True Fire and the Flame Dragon Slaying Slash for a while. Du Long turned his attention to another aspect, that is, the consumption rate of the internal fire energy blessing of the Fire Cloud Cauldron and the Flame Dragon Slaying Slash!

He must figure out his situation in this area as soon as possible, and understand how long these energy can be used in every high-intensity battle, so as not to waste his energy excessively, resulting in the final failure!

Swish, swish, swish...

In the hall, colorful and strange sword lights flashed again. Wherever the sword light passed, the space was trembling. Du Long had entered the state of using all his strength to shoot, and began to test the energy consumption speed inside the Fire Cloud Ding space when only using the Flame Dragon Slaying Slash to attack with all his strength!

Because the battle was too thrilling, he didn't have much energy to accurately calculate this energy consumption rate. Now that he is free, he can naturally focus all his attention on this aspect, and the accuracy is naturally not to doubt!

Soon, he roughly calculated the energy consumption rate when using the Flame Dragon Slaying Slash alone to attack with all his strength. The energy of the Fire Cloud Cauldron and Flame Dragon Slashing Slashing Internal Space can last about three hours!

Then he immediately entered the ultimate transformation, with the strongest attack state of three heads and twenty-four arms, blessed the internal space energy of the Fire Cloud Cauldron and the Flame Dragon Slaying Slash to the twenty-four arms, and then carried out the full-strength attack mode again!

Swish swish swish swish...

A whirlwind of sword light suddenly burst out with dazzling light in the hall. The sword lights kept flashing like a storm. Under the extremely dazzling sword light, it revealed a shocking chill, and a shocking murderous intent that strangled all the ugly world appeared and disappeared!

As many years have grown up, countless strong people have died under Du Long's sword. Now there are many more powerful people with the strength of the Heavenly Emperor Realm. In the future, more powerful people with the strength of the Heavenly Emperor Realm will fall under his sword light!

The shocking murderous intent formed by these continuous killings will definitely make countless enemies feel terrified. After reaching a certain level, they can definitely reach the point of defeating others without fighting, just as powerful as the battle holy Buddha Sun Wukong in the past!

Chi You's memory clone, who was hiding in the dark, was looking at the figure that used the sword light whirlwind in a little surprised, and was obviously shocked by his powerful aura!

Although he was just a memory clone, he had also seen countless peerless powerful people in the world. Naturally, he could see at a glance that the boundless and infinite terrifying fighting spirit in the sword light that Du Long used!

call!

After a long time, Du Long finally stopped, and the whirlwind of sword light dissipated out of thin air. He heard him murmur in a low voice: "Oh! With all his strength, the energy in the Fire Cloud Cauldron and the Flame Dragon Slaying Space can only be supported for less than an hour?!"

As he said, under the strongest attack state of three heads and twenty-four arms, the two super artifacts can only be supported for less than an hour.
Chapter completed!
