"If you have an idea, then good luck. "Long Xu couldn't help Zhao Longtian, so he could only say a polite word.

On the other side, the heart demon has already attacked, no matter what Zhao Longtian decides, the heart demon will definitely not sit still. As a product of Zhao Longtian's mind, Zhao Longtian has any thoughts, and the demons in his heart are clear. It also knew Zhao Longtian's greed.

I don't know if Zhao Longtian returned the power of the dragon soul, and he thought that his strength had decreased. The strength of the heart demon's attack on Zhao Longtian also became much smaller. However, compared to Zhao Longtian under normal circumstances, it is still a little stronger, and it is Zhao Longtian's greed that gives him the power of the demons.

Zhao Longtian's reaction was not slow, almost when the heart demon attacked, he took out his sword and collided with the heart demon. With the same action and different attack power, Zhao Longtian was shocked and took a few steps back.

Feeling that the strength of the heart demon was weaker than before, Zhao Longtian couldn't help but say, "Its strength really changes with my state of mind, but how can I get rid of my negative emotions such as killing?"

"Think of something nice. "The dragon soul reminded?

"Thinking of something nice? That seems like a good idea. Zhao Longtian groaned to himself, and met the heart demon to attack again. Immediately after teleporting away, a sword slashed out, colliding with the heart demon for the second time.

"What should I think? Zhao Longtian asked the dragon soul in his heart.

"Family, love, friendship... As long as it's beautiful, you can think about it, you don't need me to teach you, right?" The dragon soul is helpless, it has all said this, if Zhao Longtian still can't understand it, he will simply be killed by the heart demon, and the rotten wood can't be carved.

Of course, Zhao Longtian is not a rotten wood, he can comprehend the meaning of the dragon soul. When attacking the demon again, Zhao Longtian thought of his mother's meticulous care for him, thought of He Yue's help to him when he lost money on the train, thought of the team he had set up, which would get better and better in the future, thought of the simplicity and kindness of Luo Shasha and Ye Tiantian, and thought of...

Zhao Longtian has too much beauty in his heart, and he can fill a room. At this moment, Zhao Longtian remembered that those beautiful things were like a flood that burst the embankment, rushing to Zhao Longtian's heart. It's full of beauty.

Speaking of which, when Zhao Longtian wanted to be good, the inner demon was hurt a little, and it inevitably stagnated. Zhao Longtian seized the opportunity and continued to move. Fighting with the demons is to advance and attack, retreat and defend, advance and retreat, and defend and attack. Zhao Longtian is a victory, and the demon is a retreat.

The heart demon began to evade Zhao Longtian's attack, its body quietly melted, although it was very slow, but Zhao Longtian could see it really.

"Sure enough, it worked, but I didn't expect it to work so quickly. Zhao Longtian only felt incredible, and he was also full of energy when he chased the demons in his heart. In fact, this is not strange, if it weren't for Zhao Longtian's heart with too much beauty, too many beautiful people around him, too many good things, it would be more difficult to make the demon like this than to ascend to the sky. At least Zhao Longtian has a few ways to ascend to the sky, such as using a flying sword, such as taking an airplane.

"Wasn't it very powerful just now, why did you only know that you ran away now?" Zhao Longtian muttered in his mouth, chasing after the demons in his heart.

Halfway through the chase, Zhao Longtian suddenly stopped. He noticed that the black bones in the grotto were crawling up at the same time, and they all looked at Zhao Longtian, grinding their teeth constantly, as if they were singing "Rub rub, rub on smooth teeth, rub... Friction. Rub and rub, on the smooth teeth", in fact, Zhao Longtian knew that these corpses were chanting incantations. It was those spells that made Zhao Longtian have demons in his heart.

Listening to the sound of grinding teeth everywhere, Zhao Longtian was inexplicably irritable, and what he was thinking about in his brain was no longer beautiful, but some negative emotions, including the scene of the thief stealing in front of his eyes, the scene of the chengguan smashing the hawker stall, the scene of the terrorist killing people, and the scene of Li Hu's blank eyes when facing Mo Yanli...

Zhao Longtian thought about it, the black qi on the heart demon's body became stronger, and its momentum also increased exponentially.

"Not good!" Zhao Longtian wanted to control his thoughts, but found that he was so powerless, and hurriedly used the power of the dragon's whiskers to launch a heaven-level attack, chopping the surrounding corpses and bones.

Clouds of purple-black gas swirled around Zhao Longtian's body, and the sound of grinding teeth turned into whimpering. Although his voice changed, Zhao Longtian still had negative emotions in his heart, thinking about it, Zhao Longtian's eyes were actually red.

The young man appeared in front of Zhao Longtian's eyes, he recited "What is the righteous way, what is the evil way, what is the demon way", jumped off the cliff without hesitation, and practiced hard in a cave for several years. With a sword, slaughter a sect and release endless killing thoughts. Under the sunset, he dragged his tired body away, and the shadow was pulled by the elder.

Zhao Longtian's dantian was not calm now, and that black tooth exuded a rich black light in the dantian, constantly releasing black qi. After a while, two-thirds of the entire dantian space was wrapped in black qi, and the yuan energy and Hongmeng qi were constantly squeezed, approaching the dantian side.

Long Xuzu and Long Qian'er raised their heads, and they both felt a sense of oppression. Although the dark energy was still comfortable for them just now, now they had to hide on the side of the meta-energy.

"What's wrong with him, why did I cut off contact with him," Long Xuzu couldn't help but say.

"I couldn't sense him. Long Qian'er said quietly, "I hope he can survive it." "

In the grotto, Zhao Longtian stood in place with the dragon sword in his hand, his eyes became more and more red, and the demons in his heart had already attacked him. When the heart demon slashed at Zhao Longtian with a sword, Zhao Longtian didn't dodge at all, he seemed to be numb, like a puppet.

Suddenly, Zhao Longtian raised his hand and instinctively collided with the sword in the heart demon's hand. I saw a circle of violent explosions spread out in all directions at the junction of the two weapons, and a circle of red light enveloped the entire grotto.

With the appearance of the red light, a terrible scream was heard from all around the grotto, and the inner demon also quickly retreated at the same time. Immediately after, the heart demon melted at a speed visible to the naked eye, the skull shattered, and the heart demon's entire body turned into a cloud of black and purple mist.

After the heart demon died, a palm-sized black box fell out of the broken skull.

The heart demon perished, the red light in Zhao Longtian's eyes slowly dissipated, and a black vortex appeared on his forehead, it frantically absorbed the black mist in the grotto, and after a while, the thick black mist everywhere disappeared, and the entire grotto was only a closed stone door except for the corpses and bones everywhere, a stone platform, and a passage to enter.

The red light in Zhao Longtian's eyes completely dissipated, and the black teeth in the dantian frantically absorbed the black qi, and in an instant, Zhao Longtian's dantian recovered the situation of three parts of the world. Yuan energy, dark energy, and Hongmeng Qi are each divided.

"Why has the environment changed so much, what happened just now?" Zhao Longtian came back to his senses, glanced at the surroundings where the environment had changed drastically, and glanced at the dragon slaying sword he was holding, and couldn't help but say. He really couldn't figure it out, so he lost his mind for a while, and the whole environment around him changed drastically. Zhao Longtian was a little curious, where did all those fogs, heart demons, and corpses go.

"Could it be that I used some kind of special kill when I lost my mind just now and destroyed them all?" Zhao Longtian muttered.

"Boy, are you okay?" Long Xuzu's voice sounded in Zhao Longtian's heart at this time.

"It's fine. Zhao Longtian shook his head and said, "Long Xuzu, what happened just now, do you know?"

"I don't know, just now I and Long Qian'er lost contact with your body, and I couldn't see the outside at all. Dragonbeard replied.

"Oh. Zhao Longtian nodded.

At this moment, Zhao Longtian noticed the black box lying on the ground.

"What's that?" Zhao Longtian said in confusion, squatting down and picking up the black box. Although there was energy in his hand, Zhao Longtian still felt a coolness in his heart, it was a rich dark energy. Zhao Longtian had cultivated the magic refining technique, but the dark energy could not harm him.

Zhao Longtian's eyes were on the black box, and he saw a snake coiled together carved on it, the snake was lifelike, with a long head stretched out, and a snake hyacinth was spitting. The two eyes looked ahead in a strange way, making Zhao Longtian feel like he was looking at himself.

"This stuff shouldn't be simple. As Zhao Longtian spoke, he opened the black box, and lying inside was a black key and a black drawing. The drawing couldn't see any material, and Zhao Longtian could only feel that it contained dark energy. There wasn't much on the drawing, just a strange rune and nothing else.

"This thing should be of great use, go back and study it well. Zhao Longtian thought about it for a while, put everything into the storage ring, and then, Zhao Longtian looked at the stone door and walked over.

After looking at the stone door for a while, Zhao Longtian was surprised to find that there was a lock hole in the stone door, which seemed to be just enough to insert the key he had obtained earlier...
