Just wanted to say something, suddenly felt a gust of yin wind drifting by his side, Mu Chen's expression was awe-inspiring, and his phoenix eyes quickly swept over the stone room, and he didn't find anything unusual, but the feeling just now would never be wrong, there must be something hidden in this stone room.

And this thing is hiding in the shadows, staring at them embarrassed!

"Sneaky!"

Mu Chen took a step forward to protect Cheng Xi behind him, and swept the long sword in his hand, and where the sword qi passed, the accumulated white bones all turned into powder.

Yin Feng was forced to retreat by the sword qi, and he was about to retreat after hitting Xuan'er in mid-air.

Mu Chen sneered, "Want to run? How can it be so easy! ”

Seeing the retreat of the yin wind, Mu Chen raised his hand, this time it was no longer the sword qi, but the real sword edge, not only cut off the retreat of the yin wind with a sword, but also had the meaning of killing this sneaky sword with a sword.

The wind turned into fog, and it trembled visibly in mid-air.

"Pretending to be a ghost!" Mu Chen was about to strike again, but was stopped by Cheng Xi.

"How?" Mu Chen was surprised, looked back, and looked at Cheng Xi.

Cheng Xi just shook his head.

Although Mu Chen was puzzled in his heart, he didn't make another move to kill the yin wind after all.

I saw that the fog had a chance to breathe, and soon turned into a yin wind and escaped from the passage on the other side of the stone chamber.

"It's useless if you kill it, we need to find the people behind it." Cheng Xi explained his behavior just now.

Mu Chen frowned, "Do you know what that thing is?" ”

"Sort of." Cheng Xi didn't say much, but followed the direction of Yin Feng's escape.

Mu Chen had to keep up.

The two entered the stone path on the other side of the chamber.

This time, the passage was no longer as simple as before, and it was clearly built by serious craftsmen.

The walls of the stone path are smooth and neat, and oil lamps are embedded in the walls every few meters for lighting, but they are not lit.

Mu Chen observed the occasional murals on both sides of the stone road by the light of the night pearl, "This seems to be an underground palace, and the age of the murals is hundreds of years, to say the least." "Izumo swamp, a palace built hundreds of years ago...?" ”

Suddenly, as if thinking of some possibility, Mu Chen said again: "I always thought it was just a legend!" ”

"What is it?" Cheng Xi's footsteps did not stop.

"City of Light. Legend has it that 300 years ago, when the Izumo Marsh was just an ordinary mountain forest, the castle was built on the site where the Izumo Marsh is located today. It's just that later, I don't know why, Chaser Light City disappeared overnight, and the originally good mountains and forests were also full of swamps and quagmires, and even a lot of poisonous insect miasma appeared out of thin air in the swamp and did not disperse. ”

"It turns out that the city of chasing light has sunk to the ground." Mu Chen said: "So, the statement given by Yaoguang City at the beginning turned out to be true? Was it true that the City of Light was controlled by a ghost cultivator using the plague and the magic of ghostly magic back then? ”

Before the words fell, the two had already reached the end of the passage.

In front of me is a stone door.

Cheng Xi pushed the stone door open, and it was visible that it was really a large hall of considerable scale, but it was a pity that it had long been dilapidated.

In the middle of the main hall, there are many stone pillars that should have been used to bear loads, and the four walls are covered with cobwebs, but there is only dust, and there are no real living reptiles.

"Gaga, I don't think that after so many years, there are still people in the Kyushu Continent who remember the deeds of the old man back then."

The old hoarse voice echoed over the main hall, and there was no figure in sight, and there was no way to make out the direction.

Cheng Xi's eyebrows were cold.

Mu Chen also knew that they were really in big trouble this time.

Ghost repair!!

If that rumor was true three hundred years ago...
