The line of sight in the pipeline was very bad, and Song Yan could only see the direction of more than ten meters in front of him. And by chance, this place is not very spacious, so Song Yan can't use his psychic bone wings at all.

He could only move forward step by step with his legs, but it was early in the morning, there was no time limit here, and Song Yan had enough time to slowly find the brain of Shenhong. These pipes are as complex as spider webs. It's hard to tell where you're headed, and you don't know if you've gone too far or missed a fork in the road.

In this regard, Song Yan could only rely on his intuition to find it slowly. I don't know how long it has been, when Song Yan gradually felt a little tired, his front suddenly brightened. It's like coming to an oversized one. Here, Song Yan even heard the sound of breathing.

"Strange! Could this breath be from Shen Hong, but is he a fish?" After looking around, Song Yan used his divine sense to search. However, no other creatures were found in this radius. At this point, Song Yan had such a suspicion, but it seemed that the reason for writing didn't make sense in Song Yan's heart. He didn't understand why a fish breathed.

However, the events here for a period of time have made Song Yan see the wonder of the world. So even if something more outrageous happens, he won't be surprised. Without paying much attention to this voice, Song Yan kept exploring the way with his divine sense, thinking about the direction he had identified. Although there was a gentleman to help, Song Yan was not much faster, after all, the volume of this Shenhong was too large. And the internal structure of his body is also very complex. I don't know what kind of pipes are already dense and intricate, like spider webs, if they don't know whether they are blood vessels or what tissues.

The help of the divine consciousness is too small. It's almost the same as Song Yan's reliance on double eyes. The only difference is that you know where you're going to be in advance of a mile. In this way, Song Yan walked in these pipelines for seven or eight days, which was already Song Yan's limit. Seven or eight days without rest, even if he is a martial sect, it will not be good. But fortunately, as time passed, Song Yan gradually found that he seemed to be getting closer and closer to the brain of this dark Hong. On this day, Song Yan really felt the sound of a pounding heartbeat.

Song Yan was a little overjoyed when he heard this voice, because he had heard Zhang Rui say it before he came out. This Shenhong's body is very special, the location of his heart and brain is not very far, as long as he finds the heart, he will definitely be able to find the location of the brain. For this reason, Song Yan remembered these words firmly. At this time, after hearing this rhythmic sound, Song Yan had the feeling of hearing the sound of heaven. Without any hesitation, Song Yan immediately walked towards the place where the voice sounded.

In the pipe, this sound should be not far away, but after really walking, Song Yan was still surprised to find that the distance between him and the heart was definitely not close. Slowly, the sound grew stronger and stronger, until another ten days had passed. Song Yan saw such a heart the size of a house in front of him. The size of the Stygian Hung is incomparably huge, but his heart is surprisingly small, not to mention the size of a house, but compared to the huge size of the Stygian, his proportions are still too small. "Maybe it has something to do with age, right?" Song Yan muttered to himself. It was as if he already knew something about the creature.

After looking at it for a long time, Song Yan still bypassed his heart and walked towards a few places around him. Although it would be easy for Song Yan to kill this Shenhong now, he thought that he would still count on the benefits of Shenhong in the future. Song Yan still quietly held back his hand. Alone towards another tunnel. One of the benefits of this kind of Ming Hong is that she can use the space inside it after killing, but it is different from when she was alive. Once he dies, the Vientiane that has formed within him will no longer grow. And if he is allowed to live. Then this kind of Wanxian will eventually grow endlessly.

In other words, the space world inside will grow endlessly. This is an irresistible temptation for anyone. Naturally, Song Yan is also one of them. Although this heart was very far from his brain, Song Yan still walked for more than ten days before he found his true destination. Seeing something the size of a nuclear head in front of him, Song Yan really had a feeling of being ridiculous. This Ming Hung looks so big, but her brain is almost negligible. If this proportion is compared to her body, it is not an exaggeration to say that Futu is more than a big tree.

Although this thing is not the same as what I thought, there will still be a magic core inside, but Song Yan looked at the core in front of him. There is a flood of difficulty in my heart. What should I do to use the demon core to refine without harming Ming Hong? At this time, Song Yan was stumped. However, after meditating. Song Yan still doesn't have a practical method. It can only be refined together, and even if Ming Hong dies, it can only be like this, after all, Ming Hong will always have a Vientiane space after death, although he can't continue to grow, but even if it is so, it is not too small, and it is enough to just place the teachers and students of the Hongwu Academy.

Thinking of this, Song Yan was heartbroken. Then the power of the five elements in his hand gathered five, and hurriedly stepped forward to help him up. "Zhang Rui, what's wrong with you?" Song Yan didn't wait any longer, and directly asked what he was most concerned about. Seeing Song Yan mention this matter again, Zhang Rui obviously wanted to avoid it. But after seeing Song Yan's eyes full of concern. His heart softened all at once. "Woo woo woo woo ......" Before she could speak, Zhang Rui cried first.

"I ...... I didn't want to say it, even if I died, I didn't want to say it!" Zhang Rui's cry made Song Yan's heart shake a little, and he almost comforted her, and he didn't need her to continue. But Song Yan still held back his plan, after all, if he really didn't let Zhang Rui tell the truth, it was very likely that Zhang Rui would never wake up after the next fainting. Thinking of this possibility, Song Yan's heart became much firmer, even if Zhang Rui was sad, he wanted to know what was hidden in it.

Because once I knew, I would help her solve it. Otherwise, when he has to explode, it will be difficult to recover even if the gods come. "Zhang Rui! I know you have a hard time! But please say it all, after all, I can help you share some of it, so that you don't suffer alone!"

Seeing that Song Yan insisted on asking for it, Zhang Rui could only nod lightly, and then opened his mouth and revealed a shocking secret. As soon as this matter was said, Song Yan immediately felt like five thunderbolts.
