On the 26th floor, the silver-haired witch sat like an obedient schoolboy, unblinking at the female college student who was lecturing her doing experiments.

After the curtains were drawn, the light in the room was significantly darker, and the female college student lit a candle and placed a cardboard with a round hole in the middle in front of the candle to demonstrate the experiment of imaging small holes.

Eros had read this experiment in a book, but seeing it with his own eyes at the moment still felt very novel.

When the clear reflection of the candle appeared on the wall behind the cardboard, Ai couldn't help but wow. The female college student moves the cardboard back and forth, and the reflection of the candle becomes larger and smaller.

"The conclusion of this experiment is twofold, first, that light travels in a straight line in the same homogeneous substance. Second, the closer the object is, the larger and darker the image, and the farther the object distance, the smaller the image and the brighter it is. Let's do another experiment with a magnifying glass to gather light. ”

The female college student opened the curtains, and the sunlight immediately filled the whole room, she took out a magnifying glass, adjusted the angle, and shone it on a piece of white paper, and soon, the little bit after the light converged came out of the curling green smoke.

"The magnifying glass is a convex lens, which has a concentrating effect, and the light path will change after passing through the mirror, and it will gather to a point. ”

Eros's eyes lit up, and a flash of light flashed in her mind, as if she had understood something, and she thought desperately. The magnifying glass can burn the paper with only such a little sunlight, and if it can gather more sunlight, wouldn't it be more powerful?

Seeing that the goddess of love was stunned, the female college student packed up her things and said softly: "That's all for today's class, end of class." ”

The next day, in the evening, the dusty old monk rushed back to the hill next to Qifeng Temple with a yellow cloth burden on his back.

"Senior brother, I'm back, where's the goblin?"

Sitting on a big rock, Buxiu couldn't cry or laugh, his senior brother had been cultivating in the mountains all the year round, and he was about to repair his brain, "The goblin has already gone home for dinner, senior brother, you don't look at it, how long has it been? Look at the bottom of the mountain, even the construction workers have finished their work, and it's already the next day, right? Who will wait for you?"

I didn't hear it and immediately became anxious, "I brought all the magic weapons back, what should I do if the goblin runs away?"

"It doesn't matter, senior brother, as long as you set up the magic circle, I will have my own way to lure the goblins over when the time comes. After thinking about it for a day and a night, he thought that he had found a good way, and Chengzhu replied in his chest.

In the dark night, Buwen took the yellow cloth bag from his back, opened the layers of wrapping, and revealed the two magic weapons inside.

One is a brass candlestick with a rusty green stain, and it looks like an old thing. The candlestick is a lotus base at the bottom, the lotus flower above is divided into nine petals, each petal lotus leaf is inlaid with a black obsidian, a total of nine obsidian, it looks simple and solemn.

If there were witches present now, they would be shocked, and the black obsidian was the magic stone.

Buwen handed over the candlestick to Buxiu, reached out and took out the second magic weapon, which is a one-foot-long nine-ring tin rod (the appearance refers to the miniature version taken by Tang Seng in Journey to the West), the head of the rod is silver and white, divided into three semicircles, and there are three rings hanging on each semicircle, a total of nine rings, so it is called a nine-ring tin staff. A short tin rod with a length of one foot is usually used in Buddhist religious ceremonies, where monks chant while waving the tin staff, and the rings on the tin staff can make a sound when they hit each other.

The strange thing about this short tin staff in his hand is that the head of the rod is inlaid with a black obsidian, and when the tin staff is shaken, the obsidian glows and adds a solemn feeling.

These two magic weapons, together with the string of Tianbao Buddha beads that are not cultivated, are all magic weapons handed down from the master, so it is said that these three magic weapons can subdue demons and eliminate demons, but generation after generation has passed, and no one has ever seen what demons and monsters look like? Everyone also regarded this as a legend and laughed at it, otherwise they would not give the Tianbao Buddha beads to Litian if they did not cultivate.

Who would have thought that they would encounter witches, and these magic weapons would finally shine again. Buxiu vaguely knew that the obsidian on the magic weapon was the only magic weapon to restrain the goblins, but he didn't know anything about how it worked.

"Senior brother, with these two magic weapons, the goblins must be captured, I know where Chen lives most, let's kill them now." "If you don't cultivate, you can't be satisfied.

Ignoring it, he looked up at the sky and shook his head slowly, "It's night at this time, and the yin qi is in full swing, which is not conducive to you and me casting spells, so I want to say that it is better to wait until noon tomorrow, and it is the best choice to introduce the goblins into this forest when the sun is at its peak." ”

As soon as he stretched out his hand, he took out a stack of small mirrors from the yellow cloth baggage, "You and I have arranged the magic circle overnight, and tomorrow you will introduce the goblins into the forest, which will be a great achievement." ”

In the night, the master and apprentice climbed high and low, hung those small mirrors on different trees and fixed them, and worked hard for half the night.

At dawn, the old monk finished the latter preparation, put the two pieces of ritual instruments into the red cloth bag embroidered with "Hum Mani Mi Mi", and tied the bag tightly.

"Senior brother, this is foolproof, these two treasure bags can ensure that the magic weapon Buddha power is not leaked, otherwise the goblins will be scared away if they are far away, and the rest depends on the junior brother, before noon, you must attract the goblins." After saying this, the old monk sat cross-legged on the ground and closed his eyes and meditated.

What can be done if he doesn't cultivate, he thought about it for a long time yesterday and just came up with the idea of calling Chen Shi to call him and the goblins, if he didn't come, he would threaten him with the fact that there were goblins around him.

If you don't practice, it's still early, so you sit beside you and close your eyes.

In the early morning, the sun shines into the woods, a layer of white mist wells up in the forest, and the milky white blooms with dots of tender green, and in the early spring morning, the hill is filled with a layer of refreshing fragrance of plants and trees.

On the 26th floor of King's Landing, Eva had already prepared breakfast, and four chattering witches gathered around the table, no, three chattering witches looked up and down around the dumbfounded Eros.

"Eros can't be stupid to learn to learn, right? It's been like this from yesterday to now, it's so scary!" The moon stared at her red eyes and stretched out her five fingers to shake it in front of Eros's eyes.

Sophie also touched Eros's forehead with great concern, "It's not hot, it shouldn't be sick, Sister Eros, you have something to say!"

Chen glanced at Eros with great meaning, "It should be fine, when I was in high school, many nerds read to a certain extent like her, as the saying goes, if you don't go crazy, you can't live." ”

Eros finally came back to his senses and smiled apologetically at everyone, "I'm worried about you, I'm sorry, I'm fine, but I've been thinking about what the teacher taught me yesterday." ”

Chen took a bite of the fragrant bun and quipped: "Eros, why don't I help you connect with a university, and you can study?"

Eros blushed, "Lord Lord teased me, my foundation is too poor, and I still repair myself at home." ”

The five of them were talking and laughing, but they didn't know that there was a terrible trap waiting for them in Qifeng Temple.
