Ghost fire?

Zhong Ling looked at Zhong Shulan's curious gaze, her eyes flickered, she thought, if Zhong Shulan also grew up in modern times, she would not ask such a question.

Modern people know that the so-called ghost fire is phosphorus fire.

It is a natural phenomenon in which human and animal carcasses decompose in the ground, various chemical reactions occur, and then converted into phosphine, a gas, and spontaneous combustion in the air.

Of course, the ghost fire she created was certainly not formed using phosphine.

After all, phosphine is too toxic, not to mention in today's era, even in modern times, it is not easy to collect.

So, she used the calcium phosphate left in the ashes to burn, plus the reaction of silica and charcoal, to make some white phosphorus by home, and then used this guy as a scary ghost fire.

Of course, this Zhong Ling is not easy to explain to Zhong Shulan in detail, because Zhong Shulan can't understand it even after explaining.

She just said simply: "It is also a little trick formed by using a substance, which I saw from a book on the side door a few days ago, so it is natural to see these 'ghost' fires in the wild summer in the future." ”

"I see......"

"I really didn't expect that ghost fire could be artificially created."

Zhong Shulan sighed with emotion, quite a feeling of enlightenment, it turned out that there was so much to know in the book.

Suddenly, she missed her studies so much.

However, thinking of her identity as a woman, Zhong Shulan's gaze dimmed again.

But she quickly hid this emotion, looked at her brother, and continued to ask curiously: "Then tonight's little trick, is how did the ghost appear on the wall?" ”

"I took a small paper figure cut out in my hand, and refracted it with the light, and the shadow didn't just go to the wall."

After all, everyone's eyes and attention were attracted by Mo Honghua at that time.

What she was doing here, no one noticed.

"What about the black smoke?"

With this one question after another.

This night, Zhong Shulan can be said to have opened her eyes.

When she returned to the bed and lay down, she still couldn't calm the excitement in her heart, although she couldn't participate, but after listening to her brother's explanation, she seemed to have participated in such a perfect design.

It's really shocking.

Compared with Zhong Shulan's various exclamations and worships, Zhong Ling, who made this plan, was very normal.

When the old lady wanted to leave Zhang Yinghua behind, and Zhong Zhengyong and Zhong Shulan asked her to think of a way, she quickly pondered about it.

First of all, she denied the possibility of persuading Zhong Zhengzhi and Mrs. Zhong, these two people were obviously impossible to convince, so she could only let Mrs. Zhong give up by herself.

And when it comes to auto-abandonment.

At first, she thought that she was pretending to have an infectious disease with allergies, so that the old lady did not dare to let Zhang Yinghua stay, but she quickly rejected the idea.

Because if it is really so serious, then Zhong Zhengzhi will definitely not let Zhang Yinghua go back, and secondly, it is very likely that the old woman will directly lock Zhang Yinghua in a small courtyard and prevent her from coming out until she recovers or dies.

Therefore, after vetoing this idea, she was thinking about what weakness the old lady could take advantage of, and this thought, she quickly thought of the old lady Zhong's superstition.

Moreover, the old lady is not a general superstition, but rather a superstition.

Once you've confirmed this, it's better to focus on that point only.

Although there were a few hiccups in the middle, such as the teenager who almost broke down, in the end, she achieved her goal perfectly, and it was a perfect ending.

The next step is to return to the academy.

Confirming the next trip, Zhong Ling closed his eyes.
