Du Tianyi looked at Gu Yang, who was so weak, and was very worried.

For some reason, he actually had a sense of déjà vu for Gu Yang.

After all, the sentence "Xiao Gu!" suddenly popped out of his mouth, which was really suspicious.

He thought to himself, could it be that he had something to do with Gu Yang in his previous life?

However, the current situation did not allow Du Tian to think of something else, because Gu Yang's state was too bad.

Even though he was very anxious, he couldn't help anything.

At this point, he told himself to calm down, to calm down.

He let out a long breath, and then brought up all the knowledge about the underworld in his head.

But the knowledge of the underworld was too cluttered for him to know what was useful.

Finally, after a long time of reminiscing, he remembered about the fact that Yang Qi had entered the ghost body and Yin Qi had increased in evil paths.

If you think about it carefully, there are two ways for yang energy to enter the body, the first is that the ghost forcibly inhales the person's yang energy, and the second is that the person actively transports the yang energy into the ghost's body. The second way can be achieved by two methods, one is the intersection of the opposite sex, and the other is blood alchemy.

Now, for Du Tianyi, he only has one method, and that is blood alchemy.

It's a pity that he has never been exposed to these aspects, and even in the entire Guangyun Empire, there are very few people who can really do alchemy.

When he was at a loss, Du Tianyi looked at the darkness around him and became even more confused.

He let out another breath and told himself, "I won't, but let's try it first! In that case, I need a vessel that can be burned, and then firewood, and so on...... I don't have a fire, how do I light a fire? So, that's it...... Let's drill wood for fire!"

Du Tianyi didn't know what kind of place this was, he only knew that it was dark or dark here.

In this way, it was really not easy for him to find those few things.

After thinking about it, he could set his clothes on fire, but he had to find an open flame. In addition, he needs to find the container.

But where can I find this dark place?

Suddenly, Du Tianyi sat cross-legged, thinking about what Du Tianheng had taught him, concentrating his thoughts.

Wait for him to close his eyes and gather his strength in the palm of his hand.

Gradually, a faint blue flame appeared in the palm of his right hand, the color of the ocean. However, the flame can be extinguished at any time.

So, he continued to concentrate his mind and meditate.

After a while, he could feel the heat in his palm, as if that heat could drive away the cold of the underworld, but it was still very different from the open flame.

Since he could condense fire in the palm of his hand, he wanted more.

He continued to sit cross-legged, eyes closed, feeling everything in the darkness.

For some reason, after Du Tianyi sat down, he seemed to have entered an ethereal state, he could feel everything in his surroundings, but he couldn't feel his own existence.

He wanted to hear his own heartbeat, but found that there was no sound in the darkness, very quiet, eerily quiet.

At the same time, the blue flame in his palm burned bigger and bigger, and the scorching heat seemed to be scorching his skin.

In the pain, Du Tianyi slowly opened his eyes.

With that, he retracted his power, and the flames grew smaller.

Then, he bit his finger and dripped a lot of blood on the flames, and his blood was really bright red, but the color was strange against the blue flames.

In this way, his blood tumbled on the blue flames, as if it were flying freely.

Before he knew it, his eyes began to blur, and everything in his eyes, including the darkness, began to blur.

The flames were still burning, and the blood seemed to slowly solidify on them.

This darkness unconsciously seemed to invade Du Tianyi's body, causing his eyes to sink into endless darkness.

Until the next time he opened his eyes, he held a crimson pill tightly in his left hand, and if he didn't look closely, he couldn't see that there was still a faint blue light around him.

He looked at the pill in his hand in surprise, and his heart was filled with pride.

His pale lips could be revealed in the dark, but the corners of his mouth rose slightly, and then he walked to Gu Yang's side.

"The pill has finally worked!" he said excitedly.

At the same time, he saw that Gu Yang's state was much better, and he was no longer as vague as before.

Without thinking too much, he stuffed the pill into Gu Yang's mouth.

When the pill entered Gu Yang's body, he saw a burst of blue light blooming.

Gu Yang's body began to disappear again, and what was even more terrifying was that Du Tianyi actually saw blue lightning in his body.

In an instant, Du Tianyi felt that he had made a big mistake.

After all, he himself had never had experience in alchemy, which led to Gu Yang's current situation being very dangerous. Due to the impact of this anxious mood, coupled with Du Tianyi's already weak body, he collapsed without warning.

Du Tianyi, who was lying on the ground, regretted it very much, but he didn't have any strength to stand up now, so he could only watch Gu Yang's body be full of lightning.

In pain, Du Tianyi's eyes began to blur again......

It was also in the darkness, and the man in the cloak didn't know whether it was a ghost or a demon, and said coldly: "The task assigned to you has not made any progress? Not only did you not solve him in the human world, but you also let him come to the underworld? Do you want my eighteen years of hard work to be in vain?"

Behind him, a woman knelt, but she couldn't tell whether it was a human or a ghost.

"Master, your subordinates know their mistakes!, please punish your master!" The voice was very good, but it was full of fear.

"I'm not in the mood to punish you! Give you another chance! Let his soul dissipate into the underworld before he awakens! I don't want to see him the next time I wake up! Get out!"

After saying that, an unknown gas emanated from the cloak, shaking the woman a few feet away.

The woman didn't dare to say much, so she lowered her head and hurried away.

After leaving, she returned to her place in a rage.

In the dark, cold cavern, she glared at her subordinates.

"How could you be so incompetent, and let a human brat survive?" she vented all her anger.

"Ghost master, it's really inconvenient for the little one to shoot during the day, and there is a black-and-white impermanent patrol at night, really, really ......," the hanged ghost said very aggrievedly.

"You're really reasonable, aren't you? You didn't finish this thing, and you still gave me an excuse? I think you want to be scattered in this cave today?" The woman's eyes showed a vicious killing intent, which made the hanged ghost feel a chill in his heart.

"No, no, no, no, it's the little useless, it's the little incompetent!
