Chapter 21 Mystery

The blue-gray jade heart shines faintly under the suppression of Fan Youtianyan, and the hot and powerful outlines are surrounded by clouds. Nangong Shang looked at the jade heart with an uneasy look, and then looked at Lu Yu and said in a low voice, "I know what you are thinking. This thing is too dangerous. Even if you bring it around it, it is not something you can control. Get rid of it as soon as possible!"

"Can you refine this thing and make use of it?" Lu Yu still didn't give up and asked.

Nangong Shang's face changed again and again, and finally said helplessly, "You are so crazy. Who dares to touch this kind of thing? In case something goes wrong in the refining process, the resulting power will be devastating. No one will be willing to take this risk.

"Real?" Lu Yu was a little disappointed when he heard the words: "That's a pity!"

When Nangong Shang saw his appearance, he was afraid that he would cause trouble and finally said, "If you really don't want to give up, take this thing to Yanshan. Maybe someone there can help you!"

"Yanshan?" Lu Yu was slightly stunned. Yanshan was the place of Shennong's proof, and it was also the Red Emperor's Taoist field in those years. However, since the destruction of the era of the emperor, it has become a mortal place without spiritual manifestation.

"Well, you will know when you go. Of course, as long as you have enough opportunities, but before that, don't touch this thing. I'm not kidding you. This thing is dangerous!" Nangong Shang repeatedly stressed that he had a lingering palpit when he looked at this jade heart. Lu Yu nodded when he heard the words and repeatedly promised that Nangong Shang gave up.

"I'll guard the barrier for you, and you can refine the crystal marrow at ease!" Nangong Shang said in his heart for a moment.

Lu Yu nodded, and Nangong Shang jumped into a streamer, flew to the periphery of the array, and urged the magic weapon with all his strength. Seeing this, Lu Yu sat down. He pointed a little. Fan You Tianyan gathered and re-entered Yuxin into the mud pill world and suppressed it. Since Lu Yu knew the danger of this thing, he would not deal with it hastily. The green light flashed, and a trace of pure wood gasified into a giant wood and strengthened the seal. Then the boundless earth waves rose again, and the golden glow turned into a Taoist halo on the seal. Lu Yu was so safe that Lu Yu was relieved.

"Bow..."

After dealing with Yuxin, Lu Yu began to prepare to break through the barrier. A stream of light overflowed, as blue, and the strong water vapor overflowed, reflecting moving fluctuations. Xuanhai Yujing has been under the North Sea for many years, and the power of Xuanshui accumulated is pure and strong, and it has evolved fragments of the law. Lu Yu's heart is moved greatly. At this time, if he has become a mysterious prison, this crystal marrow is simply The effect of the great tonic is hundreds of times stronger than that of others, but at present, it is only the largest spiritual devourment.

"Hum..." Lu Yu pointed out, and the formula in his hand was constantly changing. The aura around him gathered but inhaled his body. A whirlpool formed around the crystal marrow. The endless aura of heaven and earth boiled violently like fuel and began to riot. Before long, a little fire finally lit up, and the blue fire rose. Although the temperature was not high, it had a fatal damage to the crystal marrow. Finally, under the continuous invasion of the fire, the crystal marrow gradually melted and rolled in the air, like jasper pulp, full of strong water vapor silk, and the fragments of the law of water began to disperse and peel away. Without the corresponding magic power, there was no way to absorb and refine it at all. At this time, Lu Yu needed was only the most essence. It's just a spiritual element.

"The monsmetic is too expensive. I really don't know how much material resources will be spent on this!" Lu Yu couldn't help sighing that the cost of a crystal marrow had just increased to a higher level. The later it is, the more energy it will need. This is a bottomless hole.

"You are a disciple of Huang Ting. Elites like you should be vigorously cultivated. If you don't have money, reach out to the top and ask for it. Otherwise, why do you want the sect!" Nangong Shang said with a smile. Lu Yu took a look at him when he heard the words. He didn't get started for a long time. Even if he was trained according to the treatment of elite disciples, he was afraid that little resource was a drop in the bucket compared with his peers.

"Did anyone from Qingqiu come during my retreat?" Lu Yu changed the topic and asked.

Nangong Shang shook his head and said, "If something so big has happened, how can they deal with us? I'm afraid they have already gone back!"

"You mean..." Lu Yu's heart moved and looked at Nangong Shang.

"The heart emperor's me, involving real dragons, such major events are naturally better than everything." Nangong Shang's face was solemn, and obviously this matter was somewhat beyond his expectations.

"The turtle refers to the tomb of the real dragon!" Lu Yu muttered to himself and then said, "What does it mean that the heart emperor left this verse? In those years, the dragon's whereabouts became a mystery. Is it found by him, just like Shennong?"

"I don't know that the tomb of the real dragon refers to the mysterious turtle. According to the literal meaning, this mysterious turtle should refer to the Haowu dome turtle, that is to say, the tomb of the dragon is there..."

"Eye of the North Sea?" Lu Yu shouted in amazsion, a little hard to believe that the eye of the North Sea is a fierce cave of the ages. Not to mention that ordinary people are difficult to access, even if there is a divine power that can penetrate into it, who will put the tomb there.

"This matter is indeed a little strange and worth considering, and that passage may not be left by the heart emperor!" Nangong Shang frowned and said in a low voice.

"It's not left by the Heart Emperor..." Lu Yu chewed repeatedly and suddenly said in an astringent voice, "You mean that the pig moved his hands and left this passage?"

"Yes, the underground palace was obviously passive and let the pig seize the opportunity. The passage may be left by him, and the matter here is not as simple as it seems!"

"What's your plan below? Do you want to leave or continue to stay in the spirit turtle world!" Nangong Shang turned the topic and seemed unwilling to discuss this matter more, so he asked. After Nangong Shang's question, Lu Yu raised his eyebrows. This time he came here and was entrusted with cloud and empty sorrow. However, after so many days, the former did not seem to have looked for him. When he needed bone jade before, he felt a little raised, and now he was even more suspicious.

"What's wrong?" In fact, I came to the turtle world for a purpose this time!" Lu Yu hesitated for a moment and recounted the causes and consequences of this trip to the North Sea. Nangong Shang lowered his head and meditated, and the gloomy color on his face became thicker and thicker. After a long time, he raised his head and said in an astringent voice, "The Holy Emperor left home... I'm afraid this matter is a little strange, not as simple as it seems.

"What do you mean?" Lu Yu hurriedly asked.

"According to what you said, Li Huang did come to the spirit turtle world in his later years and left something behind, but as far as I know, it seems to be a little unusual or even unknown..." Nangong Shang's words were deep and chilling.
