"Keep your voice down, don't let them know that we are out, let's not go out yet, go find the secret passage of Ye He's house and see what secrets he hides!" Nan Haiyue whispered softly.

"Aren't you going to cramp his muscles?"

"Don't you think it would be more interesting to dig up his family's ancestral belongings?" Nan Haiyue asked.

Lili nodded: "Soul!"

The two girls walked cautiously toward a low-lying section of the cave. Nan Haiyue's previous adventures included going to the Dragon Vein Underground Palace with the Wushuang brothers in the depths of Changbai Mountain. In fact, they didn't know anything about it, and this one of the Nalan family

It is true that I have never heard of the secret passage, and I only know that the secrets of the Nalan family are hidden inside this cave. In addition, the conversation between them just now at least shows that this secret passage is blocked by several doors and divided into several caves.

There may be dangers in everything. Nalanhong has already arrived in front of the second door. The two of them know nothing about it and can only move forward tentatively.

There are no lights in the cave, and there is no sunlight, but it does not affect vision. Nan Haiyue discovered that in addition to moss, there are some crystal stones protruding from the four walls of the cave. These crystal stones have different brilliance and reflect colorful and dazzling light.

.

"Wow...crystal!" Lili lamented that her eyes were no longer enough.

"This is a natural ore rock formation. I didn't expect that you also have this kind of mineral formation in Inner Mongolia. These are not crystals, but oxidized ores."

A copper door stood there not far away. It had been corroded by the cold and humid air over time and had a layer of green rust. There were many Manchu patterns carved on the copper door. Lili asked about this Manchu pattern.

What does it mean? Haiyue said that this should be left behind by Nalan Pearl, which means that intruders other than the Nalan family will be cursed by Nurhachi.

"Oh, you're trying to scare people with Nurhachi! Let's go in and take a look!"

This heavy copper door has a keyhole as big as a soda bottle cap, and a circle of small holes appears in the keyhole. Each small hole should correspond to a different key. Fortunately, this door has been opened, and the copper door

It's a flip-up type, and it's now turned 180 degrees. It should have been opened by Nalanhong just now.

The two girls were just about to go in when they suddenly heard a huffing sound from inside the door. Nan Haiyue quickly pressed Lili's hand, and saw a bunch of bats flying out of the door in darkness. They were huge and they didn't know how long they had been alive.

, the size of an owl, these bats are not only huge in size, but it is not known whether they have mutated after being locked in this sealed cave for a long time, and even their eyes have turned blood red.

They just flew over the heads of the two girls in a bloody storm, but did not attack them. However, Lili vaguely smelled the strange smell of these bats. There were many mosquitoes on the grassland in summer, so she hunted them by herself when she was a child.

I have also caught this kind of thing. Ordinary bats have a somewhat unpleasant smell. But the smell when the wings of these big bats are lifted is a bit like something burnt and pungent, and it also has a bit of a stink that has been left out for a long time.

The smell of garlic.

"Why does this still smell like a mug?" Lili said after the pile of big bats flew by.

"It smells like realgar and asphalt, ah! Could it be those crystal stones just now?" Nan Haiyue hurriedly got into the copper door without waiting for Lili.

There is still a cave inside the Tongmen, but the difference is that there are obvious traces of artificial excavation in this cave, and more crystal stones shining with various colors are irregularly exposed on the four walls. Among these crystal stones, there are purple, white and red.
