The three of them saw that the sun had risen, so they continued walking. Although the sun is hot, Penglai Island is surrounded by the sea on all sides. Under the blowing of the sea breeze, Xu Fu did not feel a trace of heat, on the contrary, he felt a chill coming.

As he walked, the disciple at the front shouted, "Master, look, there is a big stone gate here!" Xu Fu stopped and looked at it, and sure enough, there was a huge stone door in front of him, and the stone gate was already covered with green vines, and he couldn't see it if he didn't look carefully.

Xu Fu was about to turn his head and ask Lao Bai behind him, but he saw Lao Bai squatting on the ground in pain with his head in his hands. Xu Fu was shocked, and hurriedly ran over and asked, "Lao Bai, what's wrong with you?" ”

Lao Bai hugged his head and replied painfully: "Here... There is a powerful ... Strength. It is ... Drill into my head ... My head hurts! Yes... Yes...! After saying that, he rolled on the ground with his head in his hands.

Xu Fu hurriedly pressed Lao Bai: "Lao Bai! Are you okay? Why don't I send you back a bit? After speaking, he asked the disciple to help Lao Bai up and step back a little. It wasn't until he was far away from the stone gate that Lao Bai stopped struggling, and lay on the ground with a pale and weak face.

Xu Fu picked up the kettle and poured some water on Lao Bai's body, and asked with concern: "Lao Bai! Are you feeling better? Still have a headache? Lao Bai nodded weakly: "My head doesn't hurt as much as I just now." ”

Xu Fu asked, "What the hell is going on with you!" Why are we both okay with our master and apprentice? Lao Bai shook his head: "I don't know what's going on, I just started walking behind you, and suddenly I felt a powerful force drilling into my head, and then it seemed like my head was about to burst open." It seems that inside this stone gate is the demon king who was sealed thousands of years ago. I didn't expect it to be so powerful... Alas! ”

Xu Fu looked at the huge stone door from afar and said to Lao Bai: "Because you are a divine fish that has been cultivating for thousands of years, the demon king inside should have felt your spiritual power and thought that you would pose a threat to it, so he will drive that powerful force to attack you." And our master and apprentice are just ordinary people, without any spiritual power, and they can't pose any threat to it, so the two of us are safe. ”

Lao Bai nodded: "It should be like this, otherwise with the power of that force just now, the two of you would have already turned into pieces." Alas! ”

Xu Fu suddenly thought about something, and hurriedly said to Lao Bai: "Lao Bai, you are a divine fish, and the Tao on your body is profound. So be it! I'll teach you a mantra! It should be able to withstand the force just now. Lao Bai nodded: "Okay!" Whether it works or not, be sure to give it a try. Otherwise, if you two go inside the stone door, you will only go and never return. ”

Xu Fu took out a talisman and handed it to Lao Bai: "Lao Bai, this is the Pure Heart Mantra." You put the charm on the Mud Pill Palace, and then recite it to me" Lao Bai pasted the charm on the Mud Pill Palace and nodded: "Okay, you start!" I'll read it to you."

Xu Fu nodded and began to chant the words: "A pure heart is like water, and clear water is the heart." The breeze is silent, and the waves are not alarmed. Sitting alone, the harp whistled and sounded. Zen silence is settled, and the poisonous dragon hides. I don't know what to do, and God rewards hard work. I am righteous and awe-inspiring, and the ghosts are terrified. I am full of love, and heaven and earth return to my heart. I am ambitious, and the water is prosperous. The sky is high and the earth is wide, and the water is flowing through the clouds. Fresh and cure, straight to make a living. To the goodness of nature, the road is natural. ”

Lao Bai asked Xu Fu curiously: "What kind of mantra is this?" Xu Fu nodded: "This is the Taoist heart mantra, your spiritual power is relatively strong, this spell is simply like a tiger with wings for you!" Lao Bai nodded, and recited it a few more times before remembering the incantation.

Xu Fu said to Lao Bai: "We are going to enter the stone gate now, you can also go over and try it, if the Pure Heart Mantra is useful, go with us!" If the Pure Heart Mantra can't restrain the power just now, Lao Bai, you might as well wait for us outside! Lao Bai shook his head: "Whether it's useful or not, I must accompany you in, I don't want to watch you go in and die!" ”

Xu Fu nodded, and then walked towards the huge stone door again. Lao Bai cautiously followed behind, and sure enough, that power began to burrow into Lao Bai's head again, and Lao Bai forcibly recited the heart-purifying mantra that Xu Fu had just taught.

Sure enough, I finished reciting the heart mantra. That powerful force suddenly disappeared without a trace. Xu Fu looked at Lao Bai with a smile: "How is it?" Does this spell work? Lao Bai nodded excitedly: "This heart purification mantra is really powerful, as soon as I finish reciting the spell, I feel that the power has disappeared." ”

Xu Fu nodded, then turned around and continued to walk towards the stone gate, and after a while, all three of them came to the stone gate.

Xu Fu raised his head and looked at the huge stone door, the stone gate seemed to be born, but the stone door was carved with all kinds of charms. It can be seen that it took a lot of effort for humans and water tribes to defeat and seal the demon king thousands of years ago.

Lao Bai pushed the stone door hard, but he didn't expect the stone door to be heavy and abnormal, and it didn't move at all. Xu Fu looked around: "This stone door must be controlled by the mechanism, no matter how strong you are, it is impossible to push it." Let's take a look! Let's see where there are traps nearby! Lao Bai nodded, and then dispersed with Xu Fu's master and apprentice to find the mechanism to control the stone gate.

Sure enough, Xu Fu was right. I saw a stone dragon on the ground next to the stone gate, and the stone bead in the stone dragon's mouth was making a "woo" and "woo" sound with the wind.

Xu Fu hurriedly stretched out his hand and pulled the stone bead outside, and suddenly the sky swirled. With a rumbling sound, the stone door slowly opened.

Lao Bai was the first to step into the stone gate, and Xu Fu and his disciples also lit torches and walked in. Seeing that the ground inside the stone gate was full of white bones, Xu Fu took a closer look, and those white bones were not only human, but also some very huge skeletons.

Xu Fu looked at the white bones all over the ground, and then turned his head and continued to walk forward, in front of which was a huge cave that was particularly empty. Looking at it through the faint light of the fire, Xu Fu was suddenly stunned.

I saw that there was a very huge sarcophagus on the empty ground, and there were several human skeletons scattered next to the sarcophagus. The sarcophagus had several cracks on it, and black gas was bubbling out of each crack.

Xu Fu asked in horror: "Lao Bai, in this sarcophagus... Isn't it the sealed demon king? But this sarcophagus has cracked so many cracks, I'm afraid that the demon king will break through the seal soon! If it is not destroyed, I don't know how many more creatures in the world will die at its hands... ”

Lao Bai took a closer look at the sarcophagus, and suddenly saw a huge bronze sword inserted on the sarcophagus, and the sword body was engraved with various charms. Thanks to the millennia of sealing, the bronze greatsword is very well preserved.

Lao Bai pointed to the bronze giant sword and said to Xu Fu: "It turns out that the Demon King was suppressed here by this bronze giant sword a thousand years ago, but now that this situation is like this, this giant sword can no longer suppress the Demon King, I am afraid that it will break out of the coffin at any time, and it will be troublesome at that time." ”

Xu Fu nodded: "We must destroy it before it breaks through the seal, otherwise when it breaks out of the coffin, we may not be able to cure it, how can we destroy it?" ”
