Nangong Xia Yan followed the old abbot to the guest room.

"The little benefactor is terrible and dark at night?" The old abbot asked.

Nangong Xia Yan shook her head, she was not afraid of the dark, and it was convenient to act at night.

Let her live in a place where there is no light...... It's easier for her to move!

"Then the little donor will live here." The old abbot smiled and pushed open a door.

Nangong Xia Yan walked in to take a look, and after thanking the old abbot, he closed the door.

Oh, it's really stupid, just ask her if she's afraid of the dark, get closer to the relationship and win trust, but don't even ask how many days she wants to live, people with IQ know that there is a problem.

Momo was speechless, not everyone is as smart as you, okay. Not necessarily, including adults, let alone children.

Nangong Xia Yan looked around the room and didn't find anything wrong. Not even a secret passage.

She frowned, is there really nothing strange here?

No, she probably didn't see it.

Because Momo didn't give a hint.

Nangong Xia Yan took out a handful of unknown medicinal powder.

Throw it into the air......

Momo: [......]

Why is its host so unique?

Soon, Nangong Xia Yan found the location of the secret passage.

Its opening is so small that a normal person really doesn't notice it.

It's just that it's made of soft material all around, and the person who comes to grab people gently pushes it, and the exit is so big that it's no problem for a group of people to come in.

Nangong Xia Yan didn't intend to destroy it so easily.

She's going to tease those who want her life.

Like what......

What kind of powder is scattered at the door of this secret passage......

Carbon!

Nangong Xia Yan threatened Momo to bring carbon powder and apply it to the exit of the dark passage, as soon as they came, they must have torches, if the oxygen is not enough, the incomplete combustion of carbon will produce carbon monoxide, they will be poisoned to death, if the oxygen is sufficient, the complete combustion of carbon will produce carbon dioxide, and they will suffocate to death.

If they didn't bring torches......

Then she'll sprinkle white phosphorus!

With a ignition point of 40+, the temperature in the dark tunnel can be reached. It's absolutely fine for them to have a good feel for the fire's love for them!

But how do you make sure that the white phosphorus doesn't catch fire before they come?

Water cools down, but it also moistens white phosphorus.

What to do......

Nangong Xia Yan looked at the sky, the sky was gradually darkening, it was time for some people to take action.

"Hey, why didn't you read a book properly......"

[Momo, take a few books out and take a look.] 】

Momo: [......]

Although Momo was very reluctant, he still gave Nangong Xia Yan.

There are also included points.

[30 points will be rewarded for reading books, and 11% of lv2 progress.]

Nangong Xia Yan firmly believes that the reason why Momo doesn't want her to read is that he doesn't want her to upgrade!!

Insidious and cunning villain!

In the end, Nangong Xia Yan thought of isolating the white phosphorus with oxygen first, wrapping it in a film, and when they came over and stepped on the film, a small explosion would occur.

When the time comes...... She took the opportunity to slip away!

Sure enough...... There is a golden house in the book!

——

Night had fallen, Nangong Xia Yan sat on the bed unhurriedly, holding the water glass, watching the water in the water cup sparkle in the candlelight.

She put down her glass of water and blew out the candle.

Tonight, she's going to get the proof! Prove that this Tai Chi Market is not a good place!

——

Well, we've learned about the chemical reaction of carbon, and it's feasible, but whether the dark tunnel will still maintain a temperature of 40+ in winter, I really don't know, don't disturb the party! And white phosphorus, which is the key to causing ghost fire!
