Since Fu Lou went to the Five Elements World, he no longer felt mysterious about the Immortal Realm, although the environment of the Immortal Realm was of great help to improve the cultivation and knowledge of the monks, but his situation was special, because there were his powerful enemies there, so he was not as excited as the Dragon King.

Besides, for him, going to the fairy world is not something that cannot be done. Moreover, he thinks that as long as his cultivation is high, his longevity is long, and his body and mind can be happy, it is also good to stay in the mortal world for a while.

Thirteenth Sister Long asked Fu Lou excitedly: "Husband knows these words, are you from the earth?"

Fu Lou shook his head: "I know an earthling. ”

Long Thirteen Mei asked again: "Where is this earthling? If you can invite here, you may be able to reveal the secret of the mushroom stone forest!"

"You have a point. Fu Lou agreed.

Because it was inconvenient to say that Brother Tiancai was in the Five Elements World, so as not to reveal his secret after the thirteenth sister of Long asked, Fu Lou explained: "The whereabouts of this earthling are uncertain, and I can't find him for a while. Well, if I meet him in the future, I'll tell him, and he'll come. ”

Yuwen Jiayan smiled softly: "Why bother to seek the near and far, you can do it with your husband's skills." ”

Long Thirteen Sister was unconvinced: "Hmph! Of course I know my husband's skills! I don't need to be reminded by an outsider like you! I ...... It's always good to ask for an extra help!"

Yuwen Jiayan still smiled softly: "I'm not an outsider. ”

The thirteenth sister of Long saw that it was hard to work, so she came to a soft strategy: "Then there should always be a first come, then come, I am the boss, you are obedient to me first, maybe I will agree with my husband to accept you as a concubine when I am happy." ”

Yuwen Jiayan smiled: "Why do you need to agree? I was originally Qingfeng's wife, and who is older and who is younger must be certain." ”

Long Thirteen Mei scolded: "Dead skin!"

Fu Lou didn't participate in the boring bickering between the two, but asked the Dragon King: "Is there a way to open the Green Dragon Tomb?"

"Nope. The Dragon King shook his head without hesitation: "After years of research by our Sea Clan, there is a senior who has made a formation opening card, and it can only make this formation open once every hundred years when its power is at its weakest, and it can only last for three hours. ”

As he spoke, he took out a jade plaque and handed it to Fu Lou.

Fu Lou took the jade plaque and looked at it, this open-door jade plaque was well-made, and at first glance, it was from the hands of the formation master. He scrutinized it for a moment. It was discovered that the opening formation inside the jade plaque was extremely complicated, and it was by no means a day's work.

When he came here just now, he hurriedly used the Qiankun Method to inspect the Qinglong Tomb Formation, and with his knowledge, he felt that this formation was extremely profound.

After looking at the opening formation in the jade plaque for a while, Fu Lou couldn't help but admire this unknown dragon clan senior.

This dragon clan senior was able to find the weakness of this formation and make a jade plaque, although he did not have all the merits, but to do this, it not only required extremely high understanding and formation attainments, but also required incomparable patience and determination.

This senior also left a bold statement:

“...... If it is not my attainments that are not enough to break this array, how can I rely on the power of heaven and earth. First, it is necessary to induce a powerful lightning bolt into the deep layers of the formation, and then precisely control the lightning to open its center. Of course, this is just my assumption, because there is no such magical treasure in this world, and it is impossible for there to be a genius who controls lightning, unless it is a god in the sky. ”

“...... Since this place is located in the deep sea, ordinary lightning in the sky cannot fall. Later, I thought that if I could trigger the lightning of the Tribulation, it would be possible to break it. So, I stepped up my cultivation, and finally broke through my cultivation and triggered the Heavenly Tribulation. I was worried that no one would know about the failure of the crossing, so I left this text. ”

“...... If the descendants get this jade plaque and see this text, it means that I have failed to cross the catastrophe.........,

Seeing this, Fu Lou's expression was a little gloomy.

When the Dragon King saw this scene, he understood Fu Lou's mood, and he also sighed with emotion: "This senior's perseverance is unprecedented! He stayed here for five hundred years and never left! Just to study this Qinglong Mound, but unfortunately, later, this senior was struck by lightning during the catastrophe, and his soul was scattered. What a jealous talent!"

Fu Lou muttered to the jade plate: "I will definitely break this formation for my predecessors, so that the world can understand the talent and perseverance of my predecessors." ”

"Are you sure?". The Dragon King asked in surprise.

"Yes!" Fu Lou nodded heavily, clenched the jade plaque, his eyes were firm, and said seriously: "This senior has done his best, and he has done a very good job, just a powerful lightning bolt, and I happen to have it." ”

Long Thirteen Mei interjected excitedly: "Okay! Then hurry up and open it!"

Fu Lou smiled slightly: "I need a little time to study this formation." ”

"How long?"

"Seven days. However, if the Dragon King could provide detailed research information on the Blue Dragon Tomb by the predecessors of the Sea Clan, the time would be greatly shortened, maybe two or three days. ”

"Good!"

............

For the next three days.

Because the Dragon King has provided the research results of the Sea Clan for many years, with Fu Lou's formation attainments, the research progress is extremely fast, and he has used the Qiankun Law Eye Magic to verify while researching, so he rarely takes detours.

Such a speed made the Dragon King extremely shocked in his heart: this is the real formation genius!

The impatient Dragon Thirteenth Sister felt that three days was a long time, and she impatiently wiped it around with a silver gun, and she had several thoughts of finding a few krakens to gamble or fight, but in the end she forcibly suppressed the idea, just so as not to disturb the breeze.

Finally, Fu Lou sighed lightly, his expression flying with confidence.

The Dragon King asked expectantly, "Can you try it?"

Fu Lou nodded: "Yes, I am sure." ”

The Dragon King was overjoyed: "Good!

Fu Lou returned the jade card to the Dragon King, this jade card of the opening formation had actually begun to take effect a long time ago, but it was still a little bit of help. Then, he came to the middle of the black iron disc, and at the same time, he turned his right wrist, and a purple lightning rod was added to his hand, shining a mysterious light on the surroundings.

"It's beautiful! If only I had one. Yuwen Jiayan was a little envious.

Long Thirteenth Sister gave her a blank look: "I gave it to you, and you can't catch it!"

Zi! ......

The purple lightning rod quickly elongated, reaching the very center of the dark iron disc, without deflection or obliqueness. At the same time, the stones around the Xuantie disc lit up, and the bright light seeped out from the strokes of those runes, and became brighter and brighter, and under the background of purple lightning, the runes also became purple.

Purple runes continued to fly out of the stones, staggering in the air within three zhang, forming a magnificent text scene.

Yuwen Jiaya looked at the purple runes with a childlike smile, and couldn't help but stretch out her slender hand to grab it, but found that it was empty, it was just the light and shadow of the rune, not the real thing. However, purple runes swirled across the back of her white hand and palm, leaving behind mottled purple circles of light that she was reluctant to retract.

The purple lightning grew brighter and brighter, brighter and whiter.

Suddenly!

There was a "boom" sound from the ground, like an earthquake.

Yuwen Jiaya hurriedly retracted her hand, and then looked at Fu Lou, the dark iron disc under his feet was spinning, and he had to fly up three feet, but he still held the purple lightning tightly,

"It's going to open!" the dragon king was overjoyed when he saw this.

All the Krakens gathered around, watching this scene with excitement and incredulity.

............

Soon.

The purple lightning bolt left the Xuantie disc and retracted back into Fu Lou's hand, still returning to a lightning rod. The black iron disc beneath his feet had become smaller and smaller, and finally disappeared into the deep cavern. ...,

"It's on!haha!"

Everyone was eager to try, just waiting for the dragon king to give the order.

The Dragon King asked Fu Lou excitedly, "How long will this time last?"

Fu Lou: "As long as I don't close its center, it will always be open." ”

"Great! The virtuous son-in-law is really amazing! This time we have plenty of time to explore the treasure! We will definitely reap a lot of rewards!"

The Dragon King excitedly arranged for the first batch of people to go down and prepare to go in to explore the treasure.

At this time, Fu Lou's face suddenly changed, and he shouted, "Stand back! The yin poison is overflowing!" At the same time, the purple lightning rod in his hand changed rapidly, turning into a purple dome and quickly covering the entrance of the cave as everyone retreated.

After the krakens were frightened, they couldn't help but be disappointed: "I can't enter again, it's a pity." ”

Long Thirteen Mei looked at the entrance of the cave, this is a deep vertical cave, under the light of purple lightning, she saw twenty or thirty zhang, but did not see the fog or anything like that, and thought: Where is the poison? So, she looked into the depths again, and still saw nothing, just a black patch.

So, she asked Qingfeng: "How do you know that the yin poison is coming?"

Fu Lou was inconvenient to say that he saw the yin poison because of the Qiankun Method's eye penetration, but explained: "Well, because the cave entrance is first opened, the filthy and yin poisonous qi will come out along the cave entrance, and it is not appropriate to go down at this time." ”

"Oh, wait?"

"Hmm. Wait for the lightning to clear the poison gas before you can go down. ”

"How long will it take?"

"I don't know. ”

So, the crowd continued to wait.

............

Waiting is a frustrating thing, especially when waiting for a long-awaited result.

Long Thirteenth Sister is a very anxious person, and she is the most unwilling to wait, walking around the neighborhood as if she is on fire. Just when she was upset, she caught a glimpse of the smile on the corner of Fu Lou's mouth, and she wondered in her heart: "Such a boring formation...... It's a headache when he sees it! Why does he watch it with such relish?!"

It is true that studying complex formations requires great computing power, and calculations can be a chore for some people.

However, because Fu Lou has five spiritual roots, his soul is extremely powerful, and his calculation ability is far beyond others, and this talent makes him comfortable when calculating complex formations, and he will not feel bored at all.

At the moment, he was in a good mood.

Although the formation of the Qinglong Mound had been broken, the mystery in it made him can't help but continue to study, and combined with the situation of breaking the formation just now, he verified it, and gained further experience, in addition, he found that some subtleties would break the formation faster if they were improved.

Just as he was enjoying himself, something disturbed him.

A roaring dragon roar came from the mouth of the cave, startling everyone.

The thirteenth sister of the dragon immediately came to her senses, jumped over, and said, "That monster, the evil demon dragon, it actually woke up, it seems that even if the yin poison is cleared, we will not be able to enter." ”

As she spoke, she went to the entrance of the cave and looked inside. At this look, she was startled and exclaimed, "It's it! Those two flames! No! it's two eyes!"

"I'll go down and fight it!" Fu Lou said as he put away the purple lightning dome.

The thirteenth sister of the dragon exclaimed: "Don't go! you are looking for death......

Before he finished speaking, he saw Fu Lou leaning down......
