"What's going on, is the Alien Demon King immune to energy attacks? Qi Lan looked at Jian Gang, who had cut into the black mist but did not follow, and frowned.

"No, the Alien Demon King is not immune to all attacks," the Yan Emperor affirmed.

"So what's going on. “

Emperor Yan stared intently at the circle of black mist that was already so thick that it was close to condensation, and said thoughtfully, "I think, I'm afraid it's the reason for that circle of black fog."

"Black Mist, how can there be a way to break it?" Qi Lan didn't care what it was for, the most important thing now was to defeat the Alien Demon King while he was still at the peak.

"Well, there is. Emperor Yan said with great certainty, "This circle of black mist is the essence of alien energy that the Alien Demon King has converged over the years, and the density of negative energy can't even pass through energy. “

"What a quick way to say. "Qi Lan can be regarded as having obeyed him, the enemy is now, everything is simple.

Emperor Yan was also well aware of the enemy's situation, and said, "Where did you put the energy core left by Emperor Dark?"

Qi Lan was stunned, "What do you want to do with that, I'm sealed in the space of the Yaoguang Sword." “

Emperor Yan said with a solemn expression: "It seems that only the power of the Dark Emperor can hit the Alien Demon King." “

"Let's just say how to do it" Qi Lan didn't bother to figure out what was going on.

"Break the seal of the Dark Emperor. Emperor Yan's words were astonishing.

Qi Lan's eyes widened and said, "What did you say, I heard it right, isn't the energy of the Dark Emperor the Alien Demon King?"

Emperor Yan said, "You heard it right, the power of the Dark Emperor is not equal to the power of the Alien Demon King, but closeness, close will not be hostile, and the same close can tend to assimilate." “

Qi Lan didn't refute, after listening to Emperor Yan's words, he seemed to understand something, and said in a deep voice, "I know, let's try it." “

After speaking, Qi Lan mobilized an internal force and slowly injected it into the Yao Light Sword. In an instant, the green rays of the Yao Light Sword scattered, illuminating a space in this dim world.

In the green mang, a trace of black qi emerged, and the central point gem of the concentric six-pointed star array at the handle of the Yao Light Sword began to turn black. The black color was still spreading, slowly filling the six-pointed star array like a wave of water.

The moment the concentric six-pointed stars turned black, four pitch-black marks emanated from both sides of the handle, extending upwards along the junction between the sword body and the blade, and converged again at the blade.

After the black connection was completed, Qi Lan felt that the Yao Light Sword seemed to have changed, and the original pure wood attribute spiritual power had become a little colder, but that fierce momentum made him obviously see that the sword had become stronger.

Qing Yao didn't speak, her eyes just stared at Qi Lan firmly. It wasn't until Emperor Yan reminded him to unlock the seal of the Dark Emperor's core, Qing Yao's face changed slightly, and she wanted to say something but didn't say anything.

There was no need for Emperor Gloom to remind him, Qi Lan had already lifted the changed shaking light. The two fingers of his left hand rubbed the sword upward, and the terrifying cyan sword burst into the sky again.

The only difference from before is that the emerald green sword gang is densely distributed with magnificent black lines, which looks like a sword qi, and it is clearly a handicraft carefully carved by skilled craftsmen.

"Yaoguang, slash!" Qi Lan burst out, Yaoguang in his hand smashed down, and the hundred-meter sword gang slashed across the dim night sky with supreme might, the energy trembled violently, the space was overwhelmed, and fine lines began to appear near the sword qi, as if the sky was on the verge of shattering.

The moment the sword qi and the black mist were intertwined, in Qi Lan's stunned gaze, Jian Gang slashed straight down like a hot knife cutting butter without being stopped at all.

"That's good!" Seeing the sword qi break through the defense of the Alien Demon King, Emperor Yan couldn't help but let out a low sigh. But before the words fell, the next scene made him not even close his mouth.

Just when the sword qi touched the top of the alien demon king's head, the originally condensed figure suddenly became illusory, and the sword qi passed through the alien demon king's body as if it was passing through the black mist. From top to bottom, there is no obstacle at all and the air is slashed on the ground.

The earth trembled in the violent resonance of "boom", and the cyan sword exploded violently, and a dazzling circular light cluster slowly rose on the horizon like the sun. The terrifying energy storm crushed everything that appeared on the ground in a hundred miles in diameter around it, and even the dirt in the ground was lifted several meters.

At the same time, the center point of the light cluster, that deep black flashed away. Then, in the blink of an eye, the ground baptized by the energy storm grew dense black lines. It seemed that this layer of lines was not as powerful as Jian Gang's explosion, but even Qi Lan could feel that the ground covered by black lines was sinking at a speed visible to the naked eye. That's a radius of hundreds of kilometers, which can really be called devastating.

Qi Lan didn't expect that the blow of the Taixu Realm and the power of the dark crystal would be so strong. Perhaps, now he doesn't think about it. Quickly retract the Yao Light Sword, Qi Lan's breathing has obviously become heavy, mobilizing more than thirty percent of the internal force, and it is not easy to be distracted to control the dark crystal.

"Why is that, the Alien Demon King has no entity?!" Qi Lan asked with a heavy breath.

Emperor Yan frowned, looked at the black fog around him, and then looked at the Alien Demon King. Said thoughtfully, "No, the Alien Demon King has been reborn with the help of Cheng Tie's body, even if there are some reasons that can't hit the Alien Demon King, but Cheng Tie's physical mortal body can't dodge your attack." ”

Qi Lan said, "Don't analyze, what to do now." ”

Emperor Yan's expression changed, not angry, but a little relaxed, and a little relieved.

"The Dark Emperor's energy can indeed assimilate your attacks and break through the black mist's blocks. But his energy will also be assimilated by the Alien Demon King of the same origin as the black mist, so the sword qi just now was not not hit, or immune, but was assimilated again. ”

"This ......" Qi Lan didn't know what to say, his own strength couldn't break through the blockade of the black mist, and with the help of the power of the Dark Emperor, he would be assimilated, which meant that there was no way to cause damage to the Alien Demon King. Wouldn't that just be able to watch him fuse his alien energy and finally break through the Heavenly Dao.

"If this fate comes to this, I can't escape it. Maybe I can exchange my life for a glimmer of hope, and I can also make up for some of the sins I have committed. Emperor Yan took a deep breath and looked at Qi Lan.

"What, what are you talking about?" Qi Lan's brain is a little insufficient, what this person said is so hard to guess, is it possible that he wants to go in and die with the Alien Demon King?

Emperor Yan didn't explain anything to Qi Lan, but said to himself, "I've been studying how to defeat the Alien Demon King all these years, but I haven't made the slightest progress. The origin of the Alien Demon King is condensed negative energy, and nothing in this world can have a destructive effect on such energy. ”

After a pause, Emperor Yan continued, "In the process of research, I have been using the energy of the Dark Emperor to find the breakthrough point of the Alien Demon King. ”

Thinking of the moment when he used the Dark Emperor's energy to break through the defense of the Alien Demon King just now, Qi Lan hurriedly interjected, "Could it be that you have found it?" ””

Emperor Yan glanced at him and said, "When did I say I found it." ”

Qi Lan was a little frustrated: "Then how did you know to use the Dark Emperor's energy core to break through the defense of the Alien Demon King just now." ”

Emperor Yan was a little embarrassed, "The power of Emperor Yan and I came from the Alien Demon King, it should have an effect." ”

Qi Lan didn't want to talk anymore, it turned out that this guy was just trying. And he was really caught by his blind cat and a dead mouse.

Emperor Yan's expression became serious again, and he said, "Listen to me." At that time, I really didn't find the flaw of the Alien Demon King, but by chance I discovered the secret of my energy and that of the Dark Emperor. ”

"This matter has been said, to the point!" Qi Lan was a little crazy, was the thread in Emperor Yan's mind out of order.

"Let you hear me. "Emperor Yan was a little unhappy.

"The energy of me and the Dark Emperor is unusual, and it is possible that even the Alien Demon King does not know. Although there was no way to give it a try, it did match my suspicions. The power of our origin has a unique effect, and it will resonate with the power of the alien king. “

"It's like just using the Dark Emperor's dark attribute to make your attacks easily break the Alien Demon King's defenses against the outside world. Because this power originally belonged to him, how could his own defense defend against his own power. “

"The Dark Emperor is dark, which is equivalent to the alien energy of the Alien Demon King, so he can assimilate my attacks. Then your power is destruction, you can ......" Qi Lan seemed to have grasped something.

"Yes," Emperor Yan nodded, "Eight or nine are not far from ten, my strength should be able to allow you to attack the Alien Demon King." ”

"So what are you waiting for, come on. Qi Lan stretched out his hand and urged Emperor Yan.

Emperor Yan didn't hold Qi Lan's hand, but said, "The instinct of living beings is to survive, and in order to survive, they can destroy anything that exists. And in the time of destruction, they are no longer simply destroying, but plundering, plundering the source of life. ”

Qi Lan said impatiently, "You're here again, I know, I know." Hurry up and let's join forces and see if we can inflict heavy damage on the Demon King. ”

Emperor Yan still didn't stretch out his hand, and said, "When you make a plunder, what radiates outward is the power of endless destruction. ”

Qi Lan's expression changed slightly, and he slowly retracted his hand and said, "What do you say, is there anything wrong with the power of destruction?"

Emperor Yan's expression relaxed, and he breathed a sigh of relief, "As long as the power flowing from my body is enough to destroy everything. No one can control that kind of violent destruction. ”

Qi Lan always felt that Emperor Yan had something to say, and it was not a good word, "What is the meaning of destruction, the power of your origin is not positive energy, how can the power of destruction attached to life not be controlled." Wait, you mean, the power of the Origin?!"

Emperor Yan spread his hand, "Yes, the power of the origin, only like the Emperor of the Dark, you can use my power, and you are still alive." ”

Qi Lan seemed to slowly accept what Emperor Yan said, returned to his usual expression, and said solemnly, "Emperor Yan, I think I know, thank you." ”

"Why thank me, it's me who caused all this. Emperor Yan calmly said that there was not a trace of unusual energy fluctuations in Zhou's body. , but Qi Lan could feel that Emperor Yan was giving up his power and releasing his origin.

Without the maintenance of the power of destruction, his breath of life passed wildly, "If there is no desire for royal power, it will not be like this." What's the use of saying that now, I'm just glad that I have a chance to make up for my mistakes at the end. As he spoke, the speed at which Emperor Yan's energy was released increased instead of decreasing. Like a dam bursting, the energy poured out only to get more and more violent. Gradually, Emperor Yan's figure began to become illusory, and his voice began to become ethereal.

Without continuing to speak, Emperor Yan's gaze gradually changed. That touch of abruptness converged, endless reluctance and nostalgia came from his eyes, "Qi Lan", and his voice was a little whimpering.

"Huh?" Qi Lan agreed softly.

"If we can succeed, please don't talk about it. I'm just a dead monarch, so that my descendants can still live a normal life, thank you. ”

Qi Lan clasped his hands tightly, he knew very well why Emperor Yan was here. The world doesn't care who saved them, it only cares who harms them. Compared with those high-ranking officials and ignorant emperors of the Cheng Dynasty, Ji Yan is definitely a famous monarch through the ages. Although he took a wrong step, he used his amazing strategy and life to find a glimmer of light for mankind in the endless darkness, he, Ji Yan, and Emperor Yan are the real children of destiny and unsung heroes.

"Good all the way. Qing Yao waved her hand in the direction of Emperor Yan, her perception was keen, and she could clearly know that in order to stabilize her destructive power, Emperor Yan did not hesitate to burn her soul in the process of energy flow, refining the power of destructiveness, and making it more suitable for Qi Lan's Heavenly Dao power.

Emperor Yan's soul was dissipating, and in his phantom, a flame-type transparent gem loomed.

Qi Lan stood far away and could feel the destructive power exuding from that gem that was enough to tear everything apart.

Just as he was about to hold the Flame Essence Stone, a clear blue flame suddenly rose and enveloped the Flame Crystal. And the next moment, the flames suddenly went out. Qi Lan was surprised to find that the spar that originally revealed the fiery red color of destruction actually exuded a pink breath of life.
