Lin Mu stood outside the thunder domain for about half a pillar of incense before stepping into the thunder domain.

Lin Mu's body had just entered the thunder domain, and in the thunder domain, lightning and thunder suddenly roared, and endless heavenly thunder fell, instantly submerging Lin Mu's body, making Lin Mu completely disoriented.

Although he lost his direction, Lin Mu was not in a hurry, and with his flawless body Great Perfection cultivation, he could be unharmed in the Thunder Domain at this time.

Lin Mu walked through the minefield with difficulty, and soon approached the center of the minefield again, and saw the palace in the center of the minefield.

This is the control center of the entire Thunder Domain, and it is also the place where the best immortal stones gather.

However, after arriving here, Lin Mu did not dare to go rashly.

Although Lin Mu deduced that this was the core of controlling the entire formation, Lin Mu was not sure what dangers were here.

Not to mention other dangers, even the dense thunderstorm in the center is also very fearful of Lin Mu.

Lin Mu is here to crack everything, so Lin Mu has time.

An hour later, the trees moved, and the speed was still very fast.

An hour is exactly the time when the thunderstorm is at its weakest, so Lin Mu should take advantage of this time to quickly approach the palace in the center of the thunderstorm.

Although the speed of the forest is fast, this palace also uses the method of shrinking the ground into inches.

"Boom!"

Lin Mu finally rushed to the main hall at the last moment of the thunderstorm.

"Damn, I was almost burned into a roast suckling pig!" Lin Mu entered the main hall and scolded very tastelessly.

Raising his hand to cut off the charred clothes on his body, Lin Mu also began to observe the palace.

This is definitely a palace dug out by hand, and the distance between the forest trees before has not felt anything, but if you really go deep into it, the forest trees know the wonder of this palace.

Lin Mu had always thought that this palace might be built with some top-grade materials, and Lin Mu was even ready to dig some top-grade materials on this palace. But when he really walked in, Lin Mu found that this palace was built with ordinary bricks and tiles, and there was nothing magical about it.

But this is precisely the most amazing thing about it, ordinary palaces that can't be made of ordinary materials can withstand the ravages of thunderstorms, what a strong strength is needed to turn decay into magic.

Lin Mu walked in the palace, and he also sighed at the strength of this predecessor who built the palace.

Every plant and tree here, every building, although it is exquisite, is made of the most ordinary, even ubiquitous materials.

But such an ordinary material can finally turn decay into magic, and this cultivation alone is probably comparable to five people.

"Senior, what kind of cultivation will the people who built this place be?" Lin Mu was indeed curious in his heart, so he also opened his mouth to ask the people of the Light Dao for verification.

The Guangdao man pondered for a moment and said, "I don't know. This kind of decay is a magical means, which is not something I can deduce at all, no matter who it is, the person who built this place is a peerless and terrifying existence. ”

Lin Mu said: "Then you said that we ruined his arrangement, will he come to us?"

Guangdaodao: "I don't know about this, but I don't think it should be, since he arranged a time formation, it means that he didn't want to seal the cultivation realm forever." You're just sitting ahead of this time. ”

Lin Mu thought about it for a while, and also felt that it was such a truth.

Lin Mu walked quickly through the heavy palace, and finally appeared in the most central palace.

It was an immensely empty palace, with nothing but a map.

"It's ...... A map of the Xiuzhen Realm. Lin Mu looked at the map in front of him and was also stunned.

No one can say clearly how big the cultivation realm is, so let alone the map of the cultivation realm, but what is in front of him is indeed a map of the cultivation realm.

"This shouldn't be all, you look at the dark places next to him, I think he hasn't explored the entire cultivation realm. The Light Dao Man said, looking at some of the shaded parts of the map.

Lin Mu said: "Although I haven't been able to fully detect, it is not easy to be able to detect to such a point. I'm afraid that since the history of the cultivation realm, there has never been such a complete map. ”

The Guangdao people also nodded in agreement, and said, "That's true, even in ancient times, there was never such a complete map.

"That's the River Styx!"

Lin Mu pointed to a river that runs through four continents on the map.

There has been a legend since ancient times that the River Styx connects the four continents, and Liu Jun also came to the West Hebei from the River Styx.

But this is only a legend, no one has really seen it, and the River Styx runs through four continents.

But here, this map proves it all.

"Where is the source of the River Styx, and where is it going?" Lin Mu looked at the River Styx, also curious, wanting to know where the source of this river was.

However, this map is also incomplete, the source and end of the River Styx are all in the mysterious area, so Lin Mu can only be helpless.

"The four areas marked on it, Yingga is where the other four formation bases are located. The Guangdao people looked at the map, and the four locations that were marked also said.

Lin Mu looked at the four locations pointed out by the Guangdao people, which also corresponded to the four locations he knew, and found that they were indeed the locations of the other four formation bases.

"According to my deduction, if you want to end or accelerate the kuiba of this formation, you must have four formation bases acting at the same time, otherwise, it will only cause the explosion of the formation, which may destroy the cultivation realm. Lin Mu looked at the four formations on the four continents and muttered.

"Do I want to find four people to disturb the formation base of the four continents at the same time as me? ”

"But in the entire cultivation realm, I am the only one left with the known flawless body Great Perfection, besides me, where else are I going to find the other three people who can withstand the attack of the Thunder Domain?"

"Besides, even if you really find four people, you have to have the same mind among the four people, and you have to act together, even if you breathe slowly or quickly, it will detonate all the formations. ”

Lin Mu muttered to himself, his brows tightened more and more.

Although he found the formation and knew the solution, he could only watch and couldn't crack it, which also made Lin Mu extremely bored.

"Do I really have to find three people to cooperate with me?" After thinking for a long time to no avail, Lin Mu was also extremely depressed.

"It's so strange! this palace is so exquisite, but why doesn't there be a single formation?" the Blood Spirit Dragon suddenly spoke.
